FIG. 1 is a diagram for explaining a beverage can 100 to which the present embodiment is applied. 2A is a top view and a front view of the beverage can 100 before the closing member 300 is peeled off, and FIG. 2B is a top view and a front view of the beverage can 100 after the closing member 300 is peeled off. FIG. FIG. 2 is a top view and a front view of the beverage can 100 immediately before the closing member 300 is bonded to the container body 200. In addition, in the front view of the drink can 100 in FIG. 2, the upper part of the drink can 100 is displayed by the cross section.

  As shown in FIG. 1A, a beverage can 100 according to this embodiment is provided with a container body (can body) 200 that is formed in a cylindrical shape and contains a beverage such as a soft drink inside. Here, the container body 200 has a circular opening 210 in the upper part (at one end in the axial direction) and a bottom part in the lower part. In addition, the beverage can 100 is provided with a closing member (seal member) 300 that is bonded to an annular edge located at the top of the container body 200 and closes the entire opening 210 located inside the annular edge. ing. In the present embodiment, the adhesive strength between the closing member 300 and the container main body 200 is equal to or higher than a certain strength, so that the closing member 300 is not peeled off from the container main body 200 unless the user intends to remove it. It has become.

  Here, the annular edge of the container main body 200 is bent, and a curled portion 220 curved toward the outer side of the container main body 200 is formed on the edge as shown in FIG. Is formed. Here, when the curled portion 220 is formed in this way, the rigidity of the container body 200 is increased. In addition, when the curled portion 220 is formed, the adhesion area between the closing member 300 and the container main body 200 is increased as compared with the case where the curled portion 220 is not formed.

  Here, in this embodiment, the closing member 300 is bonded to the curled portion 220 of the container body 200. In the present embodiment, a heat sealant is applied in advance to the back surface of the closing member 300, and the closing member 300 is attached to the container body 200 by so-called thermal bonding. Here, the container main body 200 can be a two-piece can in which the body and the bottom are integrally formed, or can be formed by assembling the body and the bottom formed separately. Further, the material of the container body 200 is not particularly limited, and for example, a metal such as aluminum, paper subjected to water resistance treatment, or the like can be used.

  As shown in FIG. 2, the closing member 300 according to the present embodiment includes a base portion 310 that closes an opening 210 formed in the container body 200 and is bonded to the curled portion 220 of the container body 200. In addition, the closing member 300 includes a grip portion 320 that is provided so as to protrude outward from the edge 311 of the base portion 310 and is gripped by the user when the closing member 300 is peeled off from the container main body 200. Further, the closing member 300 according to the present embodiment has a first slit 351 provided inside the edge portion 311 and along the edge portion 311, and also located inside the edge portion 311 and along the edge portion 311. A second slit 352 is provided.

  Here, the first slit 351 has one end 351A and the other end 351B. Here, one end 351A of the first slit 351 is located on the side where the grip portion 320 is provided, and the other end 351B of the first slit 351 is on the side opposite to the side where the grip portion 320 is provided. positioned. Furthermore, one end 351 </ b> A side of the first slit 351 is formed so as to be continuous with the first side 321 of the grip portion 320. In addition, the grip part 320 of the present embodiment has a first side 321 and a second side 322 at both ends in the width direction of the grip part 320, and the one end 351 </ b> A side of the first slit 351 is the grip part. 320 is provided so as to be connected to the first side 321 of 320.

  The first slit 351 is a straight line passing through the center of the base portion 310 and out of two regions facing each other with a straight line passing through the center of the gripping portion 320 (the center in the width direction) (a straight line indicated by symbol L). It is arranged in one area. Furthermore, as shown in the top view of FIG. 2, the first slit 351 is disposed between the opening 210 formed in the container body 200 and the edge 311 of the closing member 300 (base portion 310). Note that a circular punching process is applied to a portion of the closing member 300 where the other end 351B of the first slit 351 is located. Thereby, the breakage of the closing member 300 at a place other than the first slit 351 is suppressed.

  Similarly to the first slit 351, the second slit 352 has one end 352A and the other end 352B. Here, one end 352A of the second slit 352 is located on the side where the grip portion 320 is provided, and the other end 352B of the second slit 352 is provided on the side opposite to the side where the grip portion 320 is provided. ing. Furthermore, one end 352 </ b> A side of the second slit 352 is formed so as to be continuous with the second side 322 of the grip portion 320. The second slit 352 is disposed in the other of the two regions facing each other across the straight line passing through the center of the base 310. Further, the second slit 352 is also disposed between the opening 210 and the edge 311 as shown in the top view of FIG. In the same manner as described above, a circular punching process is performed on the portion of the closing member 300 where the other end 352B of the second slit 352 is located.

  Here, in the present embodiment, an annular and band-shaped region that is located on the inner side of the edge portion 311 and is provided along the edge portion 311 of the base portion 310 is bonded to the curled portion 220 of the container body 200. . In other words, the band-like region is bonded to the curled portion 220 so as to be wound around the curled portion 220 of the container body 200. Here, in this embodiment, the band-shaped region is bonded so as to wrap around the curled portion 220 as described above, and the base of the grip portion 320 is also bonded to the curled portion 220. The grip part 320 provided outside and located outside the band-shaped region hangs downward (see FIG. 1A).

  Here, when the gripping portion 320 does not hang down, the gripping portion 320 may be in contact with the adjacent beverage can 100 or the like when the beverage can 100 is transported or displayed at a storefront, and the gripping portion 320 bends at a portion other than the base. there is a possibility. In addition, when the gripping part 320 does not hang down, when the beverage can 100 is transported or displayed at a storefront, a load is applied to the gripping part 320 by touching or catching the gripping part 320 with hands or cans. Therefore, a force for peeling off the closing member 300 is likely to act on the closing member 300. When the grip part 320 hangs down like this embodiment, it is suppressed that the grip part 320 bends other than a root and the force which tries to peel off the block member 300 acts on the block member 300. FIG.

  Here, when the beverage stored in the beverage can 100 is drunk, the grip portion 320 provided on the closing member 300 is gripped by the user, and then the grip portion 320 is pulled upward. In the present embodiment, a gap is formed between the outer peripheral surface of the container main body 200 and the grip portion 320, and in other words, the tip end side of the grip portion 320 is not bonded to the outer peripheral surface of the container main body 200. The gripper 320 can be easily gripped.

  When the grip portion 320 is pulled upward, the closing member 300 is broken at the first slit 351 and the second slit 352, and the portion (inside the first slit 351 and the second slit 352) of the closing member 300 ( Hereinafter, it may be referred to as “inner part”) is pulled upward. When this pulling is performed, the opening 210 of the container body 200 appears as shown in FIG.

  In other words, when the closing member 300 is peeled off in the present embodiment, one end (the left end in FIG. 2) of the inner portion as an example of the covering piece approaches the other end (the right end in FIG. 2) of the inner portion. Is operated by the user. More specifically, the inner portion has one end on the side where the grip portion 320 is provided, is provided so as to extend from the one end toward the right in the figure, and the other end on the downstream side in the right direction. Have. When the closing member 300 is peeled off, an operation by the user is performed so that the one end of the inner portion is lifted and the one end approaches the other end. As a result, the opening 210 appears in a region surrounded by the first slit 351 and the second slit 352.

  Here, in this embodiment, even after the opening 210 of the container body 200 appears, the adhesion between a part of the above-described band-like region (an example of an adhesive piece) and the container body 200 is maintained, and the closing member 300 is used as the container body. It remains fixed at 200. In addition, even after the opening 210 of the container main body 200 appears, the adhesion between the container main body 200 and a part of the belt-like region provided so as to extend in the left direction in the figure from the connection portion with the inner portion is maintained. Then, the closing member 300 remains fixed to the container body 200.

  More specifically, in the present embodiment, after the opening 210 of the container main body 200 appears, a part of the closing member 300 that is located outside the first slit 351 (hereinafter, referred to as “first outer part”). And a portion of the closing member 300 that is located outside the second slit 352 (hereinafter sometimes referred to as “second outer portion”) is attached to the curled portion 220 of the container body 200. It will remain as it is. For this reason, in this embodiment, the blocking member 300 is prevented from being scattered as dust.

  In the present embodiment, when the opening 210 of the container body 200 appears, the user's operating force (tensile force) acts on the first outer portion and the second outer portion via the inner portion. Specifically, in FIG. 1B, the force pulling the first outer portion and the second outer portion toward the right direction in the drawing (see arrow 1C in the drawing) is applied to the first outer portion and the second outer portion. Works. By the way, this force is a force that moves one end portion of the first outer portion and the second outer portion (see the right end portion in the figure, reference numeral 1E) toward the other end portion (see the left end portion in the figure, reference numeral 1F). 1) the outer portion and the second outer portion, the force acting in the direction indicated by the arrow 1D), and the force that tends to move one end away from the other end. More specifically, in the present embodiment, the first outer portion and the second outer portion are provided so as to extend in a direction (see arrow 1K) opposite to the direction in which the inner portion is pulled (operation direction by the user). . For this reason, the first outer portion and the second outer portion are difficult to peel off from the container body 200.

  Moreover, in this embodiment, since the said inner side part comes to peel from the container main body 200, the operation load of the closing member 300 at the time of exposing the opening 210 becomes small. In addition, in this embodiment, since it is not necessary to peel off all the portions of the closing member 300 that are bonded to the container body 200, the operating load on the closing member 300 is reduced. More specifically, since a part of the band-like region bonded to the curled portion 220 is peeled off, an operation load when the closing member 300 is peeled is reduced.

  Although depending on the user, in the configuration in the present embodiment, when the internal beverage is drunk by the user, the grip portion 320 is pulled downward, and the closing member 300 is bent as shown in FIG. . This makes it difficult for the opening 210 of the container body 200 to be covered again by the closing member 300.

  Although not described above, the closing member 300 has a laminated structure in which a resin layer and a metal layer are laminated. In the present embodiment, the metal layer included in the closing member 300 is formed of aluminum. Furthermore, in this embodiment, the container main body 200 is also formed of aluminum. Here, as in the present embodiment, when the material forming the container body 200 and the material forming the metal layer included in the closing member 300 are the same, the container body 200 and the closing member 300 are not separated. The beverage can 100 can be discarded. In other words, the beverage can 100 can be discarded without sorting for reuse.

  In addition, there is an aspect in which the opening 210 formed in the container body 200 is closed using a metal can lid having a tab, but in this case, compared to the closing member 300 as in the present embodiment, the material used is Become more. On the other hand, in the configuration of this embodiment, the thickness is smaller than that of the can lid, and less material is used. In this case, the load on the environment is reduced. Further, the closing member 300 of the present embodiment has a substantially circular shape although the portion where the grip portion 320 is provided protrudes (see the top view of FIG. 2). In other words, the outer shape of the closing member 300 of the present embodiment is unlikely to be irregular. For this reason, when the closing member 300 is cut out from the raw fabric (base material), it is difficult to produce the end material, and the load on the environment is reduced.

  In the above description, the case where the first slit 351 and the second slit 352 are provided in a state of penetrating the closing member 300 in the thickness direction of the closing member 300 has been described as an example. If the sealing member 300 is attached to the container main body 200, the closing member 300 may lose its shape. For this reason, the 1st slit 351 and the 2nd slit 352 can also be formed in the perforation shape by which the connection part and the non-connection part are arranged alternately. Further, the first slit 351 and the second slit 352 can be formed in a groove shape without being provided in a state of penetrating the closing member 300.

FIG. 3 is a view showing a modification of the closing member 300.
In the closing member 300 described above, a portion of the closing member 300 that is located outside the first slit 351 (first outer portion) is connected to the one end portion from the one end portion side where the grip portion 320 is provided. It was provided over the other end side opposite to the side. In addition, a portion (second outer portion) located outside the second slit 352 is also provided from one end side to the other end side of the closing member 300. If it adds, it was provided from the one end part to the other end part in the radial direction among the annular edge parts of the container main body 200 surrounding the opening 210.

  By the way, it is not restricted to such an aspect, For example, as shown to FIG. 3 (A), the length of a 1st outer side part and a 2nd outer side part can be made small. More specifically, the first outer portion and the second outer portion are not provided from one end side to the other end side of the closing member 300, but as shown in FIG. A first outer portion and a second outer portion can be provided from an intermediate position located between the second end portion and the other end portion to the other end portion of the closing member 300. If it adds, it can provide from the center part in a radial direction to the other end part among the cyclic | annular edges of the container main body 200 surrounding the opening 210 (refer FIG. 2).

  1 and 2, the bonding strength between the container body 200 and the closing member 300 is increased as compared with the embodiment shown in FIG. 3, but it is not necessary to increase the bonding strength more than necessary. . In the case where the adhesive strength can be secured at a certain level or higher, the adhesive area between the container body 200 and the closing member 300 can be reduced as in the present embodiment.

  In the case of the configuration of the present embodiment, when the user drinks the internal beverage, the first outer portion and the second outer portion are provided so as to be removed from the location where the user's mouth contacts, and the user drinks the internal beverage. At this time, it becomes difficult for the user's mouth to touch the first outer portion and the second outer portion. For this reason, in this embodiment, a user becomes easy to drink an internal drink. In other words, the user can drink the internal beverage without feeling a sense of incongruity. In the present embodiment, the lengths of the first outer portion and the second outer portion are half of the lengths shown in FIGS. 1 and 2, but the length is not limited to half, and the first outer portion and the second outer portion are not limited to half. The length of the part can be changed according to the adhesive strength and the like.

  Further, as shown in FIG. 3B, a wedge shape is formed between the end portion (left end portion in the drawing) of the first outer portion and the base portion 310 and between the end portion of the second outer portion and the base portion 310. This area can also be provided. More specifically, in FIG. 5B, the side 315 located at the end of the first outer portion is arranged along the radial direction of the base 310 formed in a circle as shown in FIG. Without being arranged, it is arranged so as to be inclined with respect to the radial direction. More specifically, in FIG. 5B, the side 315 is inclined so that the side 315 faces (opposites) the edge 311 of the base 310.

  More specifically, in the present embodiment, the first outer portion is provided so as to pass by the side of the base portion 310 and is provided so as to contact the edge portion 311 of the base portion 310. In addition, the first outer portion is provided along the edge 311 of the base 310 and is in contact with the edge 311, on the side farther from the edge 311 than the first side 371. A second side 372 is provided so as to be positioned and along the first side 371. In the present embodiment, the first side 371 and the second side 372 are connected by a side 315 as an example of the third side. In this embodiment, the side 315 is arranged so that the angle formed between the side 315 and the edge 311 is an acute angle. The side 316 in the second outer portion is the same, and the side 316 is formed so that the angle formed between the side 316 and the edge 311 of the base 310 is an acute angle.

  Here, when the inner part surrounded by the first slit 351 and the second slit 352 is pulled upward, if the first outer part and the second outer part move accompanying the inner part, the closing member The entire 300 is peeled off. As described above, when the angle formed between the side 315 located at the distal end of the first outer portion and the side 316 located at the distal end of the second outer portion and the edge 311 of the base 310 is an acute angle, The division of the closing member 300 at the boundary between the outer portion and the inner portion and the division of the closing member 300 at the boundary between the second outer portion and the inner portion occur more reliably. In this case, it is difficult for the first outer portion and the second outer portion to peel off from the container main body 200 together with the inner portion.

  FIG. 4 is a view showing another configuration example of the beverage can 100. 2A is a top view and a front view of the beverage can 100 before the closing member 300 is peeled off, and FIG. 2B is a top view of the beverage can 100 after the closing member 300 is peeled off. FIG. 4C is a view when the beverage can 100 is viewed from above just before the closing member 300 is bonded to the container body 200.

  In the embodiment described above, the first slit 351 and the second slit 352 are formed along the edge 311 of the base 310 in the closing member 300. In addition, in the above embodiment, the first slit 351 and the second slit 352 are formed by curves. On the other hand, in the present embodiment, the first slit 351 and the second slit 352 are linearly formed. In addition, in the present embodiment, the two first slits 351 and the second slit 352 are arranged substantially in parallel.

  Further, in the present embodiment, similarly to the above, from the one end portion side of the closing member 300 where the grip portion 320 is provided to the other end portion side opposite to the side where the grip portion 320 is provided, A first slit 351 and a second slit 352 are formed. Similarly to the above, the first slit 351 is provided so that the one end 351A side is connected to the first side 321 of the gripper 320, and the second slit 352 is the second side of the gripper 320 on the one end 352A side. 322 is provided to be connected. In addition, in order to prevent the internal beverage from leaking through the first slit 351 and the second slit 352, the first slit 351 and the second slit 352 in the present embodiment are not provided in a state of penetrating the closing member 300, and are groove-shaped. Is formed.

  Here, in this embodiment, as described above, the grip portion 320 is lifted so that the grip portion 320 is gripped by the user and the inner portion moves upward, so that the inner portion is peeled off from the container body 200. Become. Thereby, as shown to the same figure (B), the substantially rectangular-shaped opening 110 comes to be formed in the upper part of the drink can 100. FIG.

  In addition, in this embodiment, not all of the opening 210 formed in the upper part of the container body 200 appears, but a part of the closing member 300 is peeled off, so that a part of the opening 210 appears. Become. More specifically, in this embodiment, the first outer portion located outside the first slit 351 and the second outer portion located outside the second slit 352 are bonded to the annular edge of the container body 200. In addition, the first outer portion and the second outer portion extend toward the inside of the annular edge. In this embodiment, when the closing member 300 is operated by the user and a part of the opening 210 appears, the other part of the opening 210 is covered with the first outer part and the second outer part. ing.

  Here, depending on the size of the opening 210 formed in the container body 200, when all of the opening 210 appears, a large gap is generated between the user's mouth and the edge of the opening 210. . And when such a big gap arises, it becomes easy to spill an internal drink compared with the case where a gap is small. When a part of the opening 210 appears and the other part of the opening 210 is covered with the closing member 300 as in the present embodiment, the beverage inside is not easily spilled.

  Moreover, when all the insides of the said annular edge part of the container main body 200 become the opening 210 like this embodiment, an internal drink becomes easy to spill by the shaking of the drink can 100 when peeling off the closing member 300. . Here, in the case of the configuration of the present embodiment, the opening 210 is partially covered by the first outer portion and the second outer portion, so that the beverage inside is not easily spilled. In the present embodiment as well, as described above, it is not necessary to peel off all the portions of the closing member 300 that are bonded to the container body 200, so that the operation load on the closing member 300 is reduced.

FIG. 5 is a view showing another configuration example of the beverage can 100.
In the closing member 300 of the beverage can 100 shown in FIG. 5A, the separation distance between the first slit 351 and the second slit 352 on the other end side of the closing member 300 is set from the one end side of the closing member 300. It expands toward the other end. In addition, in the present embodiment, portions of the first slit 351 and the second slit 352 located on one end side of the closing member 300 are arranged so as to be linear and parallel to each other as described above. ing. On the other hand, among the first slit 351 and the second slit 352, the first slit 351 and the second slit 352 advance toward the other end of the portion located on the other end of the closing member 300. Accordingly, the distance between the first slit 351 and the second slit 352 gradually increases.

  In FIG. 5B, the separation distance between the first slit 351 and the second slit 352 is increased on one end portion side of the closing member 300. Further, on the one end side, the separation distance between the first slit 351 and the second slit 352 is gradually narrowed from the one end side to the other end side of the closing member 300. In addition, in the present embodiment, portions of the first slit 351 and the second slit 352 located on the other end side of the closing member 300 are formed so as to be linear and parallel to each other as described above. doing. On the other hand, among the first slit 351 and the second slit 352, the portion located on the one end portion side of the closing member 300 becomes gradually smaller as the separation distance advances toward the other end portion side. .

  Here, in the aspect shown in FIG. 5A, the distance between the first slit 351 and the second slit 352 is small at the portion where the user's mouth contacts (on the side where the grip portion 320 is located). The internal beverage is less likely to spill. On the other hand, in the form shown in FIG. 5A, the separation distance between the first slit 351 and the second slit 352 is large in the portion where the user's mouth does not contact, and the portion is formed in this portion. The area of the opening is increased.

  Here, in this embodiment, air is introduced into the inside of the beverage can 100 through a location where the area of the opening is large (an opening formed on the other end side of the closing member 300). If it adds, the air for the volume of the drink which decreased when the drink was drunk by the user will be introduced into the inside of the drink can 100 through the location where the area of this opening becomes large. Here, in the present embodiment, the area of the opening through which the air is introduced into the inside of the beverage can 100 is thus increased, and the introduction of air into the beverage can 100 is smoothly performed. In this case, the beverage can be discharged smoothly from the beverage can 100, and the user can easily drink the beverage inside the beverage can 100.

  Moreover, in the aspect shown to FIG. 5 (B), it is made hard to produce the spill of a drink, ensuring the ease of drinking when a user drinks an internal drink. Specifically, in the embodiment shown in FIG. 5 (B), the area of the opening at the portion where the user's mouth contacts is large, so that a sufficient amount of beverage can be secured, and the user can drink the internal beverage without feeling stressed. You will be able to drink. Moreover, in this embodiment, it is the shape covered with the closing member 300 about parts other than the part which a user's mouth touches in which internal beverage leakage may occur, and internal beverage leakage occurs. It is hard to occur.

  FIG. 6 shows an attachment device used when attaching the closing member 300 to the container body 200. In addition, the figure (A) is a figure for demonstrating the structure of a mounting apparatus, and the figure (B)-(E) is the figure which showed operation | movement of the mounting apparatus.

  As shown in FIG. 5A, the mounting device 600 of this embodiment includes a cylinder 610 provided with a rod 611 that can advance and retreat in the vertical direction in the figure, and a holder 620 attached to the tip of the rod 611. Is provided. Here, a sealer 630 that overheats and presses the closing member 300 to adhere the closing member 300 to the container body 200 is provided inside the holder 620. A spring 640 is provided between the sealer 630 and the holder 620.

  Here, the sealer 630 is provided with a heater 631 constituted by a heating wire and a temperature sensor (not shown). In this embodiment, the heater 631 is turned on / off based on the detection result of the temperature sensor. Off is controlled and sealer 630 is maintained at a predetermined temperature. The sealer 630 is made of foamed rubber and can be deformed.

  The sealer 630 is formed in a cylindrical shape and a truncated cone shape, and has a concave portion 632 into which the container main body 200 enters on the side where the container main body 200 is located. Here, the inner surface of the recess 632 is formed in a tapered shape, and its diameter gradually decreases toward the top in the figure. Further, a groove 633 along the axial direction of the sealer 630 is formed on the inner surface of the recess 632. The outer peripheral surface of the sealer 630 is also formed in a taper shape, and the diameter gradually decreases as it goes upward in the figure.

Here, when the closing device 300 is mounted by the mounting device 600, the sheet-shaped closing member 300 is placed on the container body 200 as shown in FIG. In this state, the rod 611 of the cylinder 610 is retracted, and the sealer 630 and the holder 620 are retracted upward.
Thereafter, in this embodiment, the rod 611 of the cylinder 610 advances toward the container body 200. As a result, the holder 620 and the sealer 630 advance toward the container main body 200, and the upper portion of the container main body 200 enters the recess 632 formed in the sealer 630, as shown in FIG. Further, the bottom surface 634 of the recess 632 of the sealer 630 (see FIG. 5A) contacts the container body 200 via the closing member 300, and the closing member 300 is pressed toward the container body 200 by the sealer 630. The closing member 300 is heated by the sealer 630.

  In this embodiment, the diameter (inner diameter) on the inlet side into which the container body 200 enters the recess 632 formed in the sealer 630 is larger than the diameter (outer diameter) of the base 310 (see FIG. 2) of the closing member 300. It has become. For this reason, in this embodiment, when the closing member 300 enters the recess 632 of the sealer 630 (see FIGS. 3A and 3B), the closing member 300 smoothly enters the sealer 630.

  Here, when the diameter of the inlet side of the recess 632 formed in the sealer 630 is smaller than the diameter (outer diameter) of the base 310 of the blocking member 300, the blocking member 300 is blocked when entering the recess 632. Misalignment of the member 300 is likely to occur. In the configuration of the present embodiment, as described above, since the diameter of the recess 632 on the inlet side is larger than the diameter of the base 310 of the blocking member 300, it can occur when the blocking member 300 enters the recess 632. Positional displacement of the closing member 300 is less likely to occur.

  Here, in the present embodiment, when the sealer 630 is moving toward the container body 200, the inner peripheral surface of the sealer 630 is formed in a taper shape. An edge 311 (see FIG. 2) of the base 310 is pressed downward by the inner peripheral surface of the sealer 630. More specifically, in this embodiment, the edge 311 of the base 310 of the closing member 300 is pressed downward in FIG. 6 by the inner peripheral surface of the sealer 630, and the edge 311 is pulled downward.

  Further, in this embodiment, when the bottom surface 634 of the recess 632 contacts the container body 200 via the closing member 300 and the closing member 300 is pressed by the bottom surface 634, as shown in FIG. The above-described belt-like region located inside the edge portion 311 (see FIG. 2) and disposed along the circumferential direction of the base portion 310 is bent downward. In addition, the grip portion 320 also hangs downward by bending the belt-shaped region downward. In the present embodiment, as described above, when the sealer 630 descends, the edge 311 of the base 310 is pulled downward. For this reason, in this embodiment, in the state shown to the same figure (B), it will be in the state in which the wrinkle has not generate | occur | produced much in the closing member 300. FIG.

  Thereafter, in this embodiment, the rod 611 is further advanced, and the holder 620 is advanced with respect to the sealer 630 as shown in FIG. 3C, and the spring located between the sealer 630 and the holder 620. The sealer 630 is pressed by the holder 620 through 640. Thereby, the closing member 300 is further pressed by the sealer 630, and the closing member 300 is further pressed against the container body 200.

  Further, when the rod 611 is further advanced, the sealer 630 enters the holder 620 as shown in FIG. 5C. At this time, the sealer 630 formed in a tapered shape is inserted. The outer peripheral surface is pressed by the inner peripheral surface of the holder 620. As a result, the sealer 630 formed in the shape of a truncated cone is deformed inward, and the portion of the closing member 300 located outside the curled portion 220 (see FIG. 2) (the outer peripheral surface of the curled portion 220 is opposed). The part) is pressed and heated by the sealer 630.

  In the present embodiment, when the container body 200 enters the sealer 630 (see FIGS. 6A and 6B), the grip portion 320 of the closing member 300 is placed on the inner peripheral surface of the recess 632 of the sealer 630. It enters into the formed groove 633. For this reason, as described above, even when the sealer 630 formed in the shape of the truncated cone is deformed inward and the closing member 300 is pressed toward the container main body 200, the gripping portion 320 is applied to the container main body 200. There is no pressing. In this case, adhesion of the grip portion 320 to the container body 200 is avoided.

  Here, although the description is omitted above, the closing member 300 in the present embodiment is formed by performing a punching process after applying a heat sealant to a sheet-like base material using a roller. For this reason, in this embodiment, the heat sealing agent (adhesive) is applied to the entire back surface of the closing member 300. For this reason, if the grip part 320 is pressed against the container body 200 by the sealer 630 without providing the groove 633 as described above, the grip part 320 is bonded to the container body 200. And if such adhesion | attachment is made, it will become difficult to peel off the closure member 300 from the container main body 200. FIG. For this reason, in this embodiment, the groove | channel 633 is provided in the sealer 630, and the adhesion to the container main body 200 of the holding part 320 is made.

  In this embodiment, the spring 640 is disposed between the sealer 630 and the holder 620. However, the spring 640 can be omitted and the sealer 630 can be directly pressed by the cylinder 610. In this case, it is necessary to reduce the pressure of the compressed air supplied to the cylinder 610 in order to prevent damage to the apparatus. In this case, the operating speed of the cylinder 610 is reduced.

  For this reason, in this embodiment, a spring 640 is provided between the cylinder 610 and the sealer 630, and the sealer 630 is pressed via the spring 640. In this case, the pressure of the compressed air can be set to a high value, and the operating speed of the cylinder 610 can be increased. Note that the pressing force when the sealer 630 presses the closing member 300 can be changed by changing the spring 640.

  After the operation shown in FIG. 6C is completed, in this embodiment, as shown in FIG. 6D, the cylinder 610 is driven and the rod 611 is retracted upward. Thereby, first, as shown in the figure, the pressing of the outer peripheral surface of the container main body 200 by the sealer 630 is released. At this time, the sealer 630 is pressed against the upper part of the container body 200 from above, and the container body 200 is unlikely to fall down. Thereafter, as shown in FIG. 5E, the rod 611 is further retracted upward. As a result, the sealer 630 is separated from the closing member 300. Thereby, the heating of the closing member 300 is finished, and the curing of the melted adhesive is started.

  FIG. 7 is a view showing another configuration example of the beverage can 100. 2A is a top view and a front view of the beverage can 100 before the closing member 300 is peeled off, and FIG. 2B is a top view and a front view of the beverage can 100 after the closing member 300 is peeled off. FIG. In addition, in the front view of the drink can 100 in the same figure (A), the upper part of the drink can 100 is displayed by the cross section.

  As shown in FIG. 4A, the beverage can 100 according to the present embodiment has a circular opening 210 at the top and a bottom at the bottom and is formed in a cylindrical shape, as described above, and can be used for soft drinks and the like. A container body (can body) 200 in which a beverage is accommodated is provided. Further, the beverage can 100 is provided with a closing member 300 that is bonded to an annular edge located at the upper part of the container body 200 and closes the entire opening 210 of the container body 200, as described above.

FIG. 8 is a view showing the container body 200 and the closing member 300 immediately before the closing member 300 is attached to the container body 200.
Similarly to the above, the closing member 300 in the present embodiment covers an opening 210 formed in a circular shape at the top of the container body 200, and a cover piece whose outer peripheral edge is bonded to the curled portion 220 of the container body 200. Another example base 310 is provided. Further, a grip portion 320 is provided so as to protrude outward from the edge (outer peripheral edge) 311 of the base portion 310 and gripped (operated) by the user when the closing member 300 is peeled off from the container main body 200. . Moreover, in the closing member 300 in this embodiment, as shown also in FIG. 7, it is provided so that it may protrude toward the outer side from the edge 311 of the base 310, and it is opposingly arranged to the outer peripheral surface of the container main body 200, and this outer periphery. An adhesive portion 330 is provided as another example of an adhesive piece that is adhered to the surface. The adhesive portion 330 is provided on the side opposite to the side on which the grip portion 320 is provided with the base portion 310 interposed therebetween.

  Also in the present embodiment, a band-like region located inside the edge portion 311 of the base portion 310 is bonded to the curled portion 220 of the container main body 200. Further, in the present embodiment, the grip part 320 and the adhesive part 330 hang down due to the adhesion of the band-shaped region to the curled part 220. Furthermore, the adhesion part 330 and the outer peripheral surface of the container main body 200 in a state of hanging downward are adhered. Thereby, the beverage can 100 shown in FIG. 7A is completed. In addition, the closing member 300 in this embodiment is also adhere | attached on the container main body 200 with the mounting apparatus 600 demonstrated above.

  Here, when the beverage stored in the beverage can 100 is drunk, the grip portion 320 as an example of the operation piece is gripped by the user, and then the grip portion 320 is pulled upward. In the present embodiment, a gap is formed between the outer peripheral surface of the container main body 200 and the grip portion 320. In addition, the tip end side of the grip portion 320 is not bonded to the outer peripheral surface of the container main body 200. The gripping part 320 is easily gripped. When the grip portion 320 is pulled upward, a portion of the closing member 300 that is bonded to the container main body 200 and is located on the side close to the grip portion 320 is peeled off from the container main body 200.

  Thereafter, peeling of the closing member 300 from the container main body 200 proceeds from the side where the grip portion 320 is provided to the side where the adhesive portion 330 is provided. Then, when the peeling of the closing member 300 from the container body 200 is completed, the circular opening 210 formed in the upper part of the container body 200 is exposed as shown in FIG. 7B. In addition, in the present embodiment, all of the circular openings 210 appear.

  In this embodiment as well, after the closing member 300 is peeled off from the container main body 200, the closing member 300 remains attached to the container main body 200 by the adhesive portion 330 fixed to the can body surface of the container main body 200. Become. For this reason, also in this embodiment, the blocking member 300 is prevented from being scattered as dust. Here, when the diameter of the container main body 200 is small, it is difficult to secure a bonding area between the closing member 300 and the container main body 200. However, as in the configuration of the present embodiment, the closing member is against the outer peripheral surface of the container main body 200. When bonding 300, it becomes easy to ensure a bonding area.

  Although depending on the user, when the beverage inside is drunk by the user, the grip portion 320 is pulled downward. In this case, as shown in FIG. 7B, the closing member 300 is bent around the connection portion between the base portion 310 and the bonding portion 330. This makes it difficult for the opening 210 of the container body 200 to be covered again by the closing member 300. In the present embodiment, the first slit 351 and the second slit 352 described above are not provided, and the operation load required to peel off the closing member 300 is larger than that in the embodiment described above. Become.

FIG. 9 is a view showing a modification of the closing member 300. In FIG. 9, the container main body 200 is also displayed.
In the closing member 300 shown in FIG. 7A, the width W of the bonding portion 330 is larger than the width of the bonding portion 330 shown in FIGS. In other words, the width W in the circumferential direction of the bonding portion 330 bonded to the outer peripheral surface of the container main body 200 along the circumferential direction of the container main body 200 is larger than the width of the bonding portion 330 shown in FIGS. doing. Here, when the width of the bonding portion 330 is increased as described above, the separation between the container body 200 and the closing member 300 is further less likely to occur.

  In the aspect of FIG. 5A, a connection portion 340 that connects the base portion 310 and the adhesive portion 330 is provided, and the width of the connection portion 340 is made smaller than the width of the adhesive portion 330. In addition, in the present embodiment, the width of the base of the bonding portion 330 is smaller than the width of the tip in the protruding direction of the bonding portion 330. Here, when the connecting portion 340 having a small width is not provided (when the wide adhesive portion 330 is directly connected to the base portion 310), it is difficult to bend the base portion 310 after being peeled from the container body 200. In other words, the base 310 is easily disposed on the extension line of the bonding portion 330, and the nose of the person who drinks the beverage can easily touch the base 310. For this reason, in the present embodiment, by reducing the width of the connecting portion 340 as described above, the rigidity of the closing member 300 is partially weakened and the base portion 310 is easily tilted.

  In addition to the method of enlarging the adhesion part 330, the adhesive body is changed and the adhesion strength between the closing member 300 and the container body 200 is increased to make it difficult for the container body 200 and the closing member 300 to be separated. . By the way, in this case, the adhesion strength between the base 310 and the container main body 200 also increases, and it becomes difficult to peel the base 310 from the container main body 200. For this reason, in this embodiment, separation of the container main body 200 and the closing member 300 is made difficult to occur by increasing the bonding area between the bonding portion 330 and the container main body 200.

With reference to FIG. 9B, another modification of the closing member 300 will be described.
In the closing member 300 in this figure, the adhesive portion 330 and the grip portion 320 are formed so that the shape of the adhesive portion 330 and the shape of the grip portion 320 are the same. More specifically, the adhesive portion 330 is disposed on one side of the base portion 310, and the grip portion 320 is disposed on the other side of the base portion 310. More specifically, the grip portion 320 is disposed on one region side of two regions facing each other across the virtual straight line 9B passing through the center of the base portion 310 formed in a circle, and at one end portion of the base portion 310. It is connected to one end in the direction orthogonal to the virtual straight line 9B. The adhesive portion 330 is disposed on the other region side of the two regions, and is connected to the other end portion of the base portion 310 in the direction orthogonal to the virtual line 9B. . In the present embodiment, the closing member 300 is formed so as to be line symmetric with respect to the virtual straight line 9B as an axis of symmetry.

  The closing member 300 shown in FIG. 9B is also fixed to the container main body 200 by the mounting device 600 shown in FIG. 6. At this time, the position (phase) of the closing member 300 is shifted by 180 °. However, the closing member 300 can be bonded to the container body 200. For this reason, in the configuration of the present embodiment, it is possible to reduce management items and reduce work errors. In this case, cost reduction can be realized.
