Description

  The present invention relates to a packaging box for packaging food, daily necessities, and other articles. More specifically, the present invention relates to a box body having a side wall portion formed in an annular shape and a bottom portion closing a lower end opening of the side wall portion, and a side wall portion. It is related with the packaging box provided with the cover body comprised so that obstruction | occlusion of the upper-end part opening of this was possible.

  Conventionally, various types of packaging boxes for packaging articles such as foods and daily necessities have been provided. As one of them, the annularly formed side wall and the lower end opening of the side wall are closed. A box body having a bottom portion and a lid body configured to be able to close an upper end opening of the side wall portion, and the side wall is formed by externally fitting the lid body to the box body (side wall portion) in a state where an article is accommodated in the side wall portion. A so-called stamping type packaging box which closes the upper end opening of the part is well known.

  And since this kind of packaging box is adapted to externally fit the lid body to the side wall portion of the box body, there is a step between the side wall portion and the outer periphery of the lid body. There is also provided an apparatus in which the outer peripheral surface of the body and the outer peripheral surface of the side wall portion are flush with each other (see, for example, Patent Document 1).

In the box body of such a packaging box, an inner frame or an inner box is housed in an outer box whose upper part is open, and an upper end portion of the inner frame or the inner box extends upward from the upper end of the outer box. Thus, the packaging box has a step formed at the upper end of the side wall, and the outer peripheral surface of the lid and the outer peripheral surface of the side wall are flush with each other with the cover fitted on the upper end of the side wall. It is supposed to become. Therefore, such a packaging box is often used for packaging gifts and the like because it has a clean appearance and looks good.
Japanese Utility Model Publication No. 5-94118

  By the way, although the packaging box of the said structure is comprised with the external appearance, it has the problem that a cover body removes carelessly from a box main body only because a cover body is only externally fitted to a box main body. In particular, when the height of the box body (side wall portion) in the vertical direction is set low, it is not possible to sufficiently secure a region in which the lid body can be externally fitted to the side wall portion (overlap of the lid body with respect to the side wall portion). For this reason, the possibility that the lid body falls off from the box body is increased.

  Therefore, the present invention can improve the appearance of the appearance and can reliably prevent the lid from being inadvertently removed regardless of the height of the box body that accommodates the article. It is an issue to provide.

  A packaging box according to the present invention comprises a box body having a side wall portion formed in an annular shape and a bottom portion that closes a lower end opening of the side wall portion, and a lid configured to be able to close an upper end opening of the side wall portion. In the packaging box provided, the box main body has an upper end protrusion that protrudes inward from the entire periphery of the upper end portion of the side wall portion or a plurality of locations, and an entire periphery of the inner periphery of the side wall portion at a position lower than the upper end protrusion portion. Or an internal extension portion extending inward from a plurality of locations, wherein the lid body is formed so as to be able to close the upper end opening of the side wall portion, and at least the outer peripheral edge portion is made of a sheet material that can be deformed. A main body portion and a gripping portion extending to the upper surface side of the lid main body portion, and the lid main body portion has an outer peripheral edge portion that can be placed on the inner extension portion within the side wall portion, and is formed on the upper end protruding portion. It is formed so that it can oppose.

  According to the packaging box having the above configuration, when the lid is pushed into the upper end opening of the box main body (side wall portion), the outer peripheral edge of the lid main body is deformed and the inner extension portion is moved over the upper end protruding portion. The upper end opening of the side wall is closed. In this way, when the lid body is placed on the internal extension within the side wall, there is no lid on the outer periphery of the packaging box (box body), so there is a step or the like on the outer periphery due to the presence of the lid. It is not formed, and it looks nice and innovative.

  Then, when the lid attempts to move upward in a state where the upper end opening of the box body is closed, the outer peripheral edge of the lid main body is locked to the upper end protruding portion facing upward, and the lid Inadvertent removal of the body is prevented. Thus, the packaging box having the above configuration is affected by the amount of overlap of the lid body with respect to the box body, that is, the vertical height of the box body (side wall portion), as in the case of the conventional Inba type packaging box. Therefore, it is possible to reliably prevent the lid from being inadvertently detached. When the user holds the gripping part and intentionally lifts the lid, the outer peripheral edge of the lid body part is deformed and the packaging box having the above structure gets over the upper end protruding part. Can be removed.

  As one aspect of the present invention, the upper end protruding portion may be formed by curling the upper end portion of the side wall portion inward. In this way, the side wall portion and the upper end protruding portion are integrally formed, so that it is sufficient for the force generated when the lid body is attached and detached (when the outer peripheral edge portion of the lid main body can ride on the upper end protruding portion). It is possible to obtain a strength that can withstand.

  As another aspect of the present invention, the upper end protrusion and the internal extension may be provided over the entire inner periphery of the side wall. In this way, when the upper end opening of the side wall portion is closed with the lid, the entire periphery of the outer peripheral edge of the lid body is received by the internal extension, and stable mounting is possible. Further, when the lid is about to move upward, the entire periphery of the outer peripheral edge of the lid body is received by the upper end protruding portion, and the lid can be reliably prevented from falling off.

  Furthermore, as another aspect of the present invention, the internal extension portion is arranged so as to sandwich the outer peripheral edge portion of the lid main body portion together with the upper end protruding portion in a state where the upper end opening of the side wall portion is closed by the lid body. May be. In this way, since the lid body does not move in the vertical direction with the upper end opening of the side wall portion closed with the lid body, the lid body can be attached in a stable state and the appearance is improved. can do.

  As described above, the packaging box according to the present invention can improve the appearance and ensure that the lid is inadvertently removed regardless of the height of the box body that houses the article. An excellent effect that it can be prevented can be obtained.

  Hereinafter, a packaging box according to an embodiment of the present invention will be described with reference to the accompanying drawings.

  As shown in FIGS. 1 and 2, the packaging box according to the present embodiment includes a box body 10 having a side wall portion 11 formed in an annular shape and a bottom portion 12 closing a lower end opening of the side wall portion 11, and the side wall portion 11. The lid body 20 is configured so as to be able to close the upper end opening H thereof.

  As for the said box main body 10, the side wall part 11 is formed in an annular | circular shape or an annular | circular shape according to a packaging form. That is, the side wall portion 11 is formed in a rectangular tube shape or a cylindrical shape, and is formed in a cylindrical shape (annular shape) in the present embodiment. The side wall portion 11 is formed by bending a sheet-like material (in this embodiment, a paper material (thick paper)) into an annular shape. Since the side wall part 11 according to the present embodiment is formed in an annular shape (cylindrical shape) as described above, the rectangular sheet material is rounded (bended) into a cylindrical shape, and the overlapping ends are joined together with an adhesive or the like. It is formed by doing. The side wall 11 is decorated by applying predetermined printing on the outer peripheral surface or pasting decorative paper such as Japanese paper with a predetermined color, pattern, or the like.

  As shown in FIGS. 1A and 2, the box body 10 according to this embodiment includes an upper end protruding portion 13 that protrudes inward from the entire inner periphery of the upper end of the side wall portion 11, and the upper end protruding portion 13. The internal extension part 14 extended inward from the perimeter of the inner periphery of the side wall part 11 is provided.

  The upper end protruding portion 13 protrudes toward the inside of the side wall portion 11 to such an extent that does not hinder the insertion and removal of the article P into the side wall portion 11. The upper end protruding portion 13 according to the present embodiment is formed by curling the upper end portion of the side wall portion 11 inward. That is, in the box body 10 according to the present embodiment, since the side wall portion 11 is made of paper material (thick paper), the upper end protrudes by rounding (curling) the paper material constituting the side wall portion 11. The part 13 is formed integrally with the side wall part 11.

  The internal extension portion 14 is formed in an endless annular shape in plan view, and defines an entrance through which the article P is taken in and out of the side wall portion 11. The internal extension portion 14 according to the present embodiment is formed by cutting (or punching) a sheet material different from the sheet material constituting the side wall portion 11 into a ring shape (doughnut shape) in plan view. The outer periphery is bonded to the inner peripheral surface of the side wall 11. Thereby, the internal extension part 14 is in the state extended toward inner side (center of the side wall part 11) from the inner periphery whole periphery of the side wall part 11. FIG.

  The internal extension portion 14 is disposed at a position where a gap is formed between the upper end protruding portion 13 and an outer peripheral edge portion of the lid 20 (lid body portion 21 described later). The internal extension part 14 according to the present embodiment is arranged so that the distance from the upper end protruding part 13 is the same or substantially the same as the thickness of the outer peripheral edge of the lid body 20. That is, the internal extension 14 is disposed at a position where the outer peripheral edge of the lid 20 can be sandwiched together with the upper end protrusion 13.

  As described above, the internal extension portion 14 demarcates the entrance / exit of the article P, and therefore does not hinder the entry / exit of the article P, and receives the outer peripheral edge portion of the lid 20 (lid body portion 21 described later). The extension amount can be set. For example, when the upper end protruding portion 13 is formed by curling, the protruding amount of the upper end protruding portion 13 is not less than five times the protruding amount of the upper end protruding portion 13 based on the inner peripheral surface of the side wall portion 11, preferably, It is set to be not less than three times the amount of protrusion of the upper end protrusion 13 and not less than the amount of protrusion of the upper end protrusion 13.

  And as shown in FIG. 2, the said side wall part 11 is formed with the bottom receiving part 15 which receives the bottom part 12 in a lower end part. The bottom receiving portion 15 is formed so as to protrude toward the inside of the side wall portion 11. The bottom receiving portion 15 according to the present embodiment is formed integrally with the side wall portion 11 by rounding (curling) the paper material constituting the side wall portion 11, similarly to the upper end protruding portion 13. .

  The bottom 12 is formed by cutting (or punching) a sheet material so as to correspond to the inner shape of the side wall 11. The bottom portion 12 is bonded and fixed to at least one of the side wall portion 11 and the bottom receiving portion 15 in a state where the outer peripheral edge portion is placed on the bottom receiving portion 15 in the side wall portion 11.

  The lid body 20 is formed so as to be able to close the upper end opening H of the side wall portion 11, and at least the outer peripheral edge portion is formed of a sheet material that can be deformed, and on the upper surface side of the lid body portion 21. And an extended gripping portion 22.

  The lid main body portion 21 according to the present embodiment is entirely made of a paper sheet material (thick paper), and can be deformed not only at the outer peripheral edge portion but also as a whole. The lid body portion 21 is formed such that the outer peripheral edge portion can be placed on the internal extension portion 14 in the side wall portion 11 and can face the upper end protruding portion 13. In the present embodiment, since the side wall portion 11 is formed in a cylindrical shape, the lid main body portion 21 is formed in a disk shape. The lid body 21 has an outer diameter that is smaller than the inner diameter of the side wall 11 and larger than the inner diameter of the upper end protrusion 13 and the inner extension 14.

  The lid body 21 is decorated by applying predetermined printing on at least one surface (upper surface) or attaching decorative paper such as Japanese paper with a predetermined color or pattern. Has been.

  The grip portion 22 is formed integrally with the lid main body portion 21. That is, the gripping portion 22 is formed to extend to one surface (upper surface) side of the lid main body portion 21 by cutting and raising a part of the outer peripheral end portion of the lid main body portion 21.

  The packaging box 1 which concerns on this embodiment consists of the above structure, and demonstrates the usage aspect of this packaging box 1 next.

  First, an article P to be packaged is accommodated in the box body 10 (side wall portion 11), and the other surface of the lid body portion 21 is projected so that the gripping portion 22 protrudes upward as shown in FIG. The lid 20 (lid body portion 21) is pushed into the upper end opening H of the box body 10 (side wall portion 11). Then, since the outer diameter of the lid main body portion 21 is set larger than that of the upper end protruding portion 13, the outer peripheral edge portion gets over the upper end protruding portion 13 while being deformed.

  Then, when the outer peripheral edge gets over the upper end protruding part 13, the lid main body part 21 enters the side wall part 11 as shown in FIGS. 1B and 2, and the outer peripheral edge part is on the inner extension part 14. While being placed, the outer peripheral edge portion opposes the upper end protruding portion 13 on the upper side. In this state, the lid main body portion 21 exists in the entire upper end opening H of the side wall portion 11 (the opening region defined by the upper end protruding portion 13 and the opening region defined by the internal extension portion 14). 11 upper end opening H is closed.

  In the present embodiment, the distance between the upper end protrusion 13 and the internal extension 14 is set to be the same as or substantially the same as the thickness of the lid body 21 (the outer peripheral edge of the lid body 21). In a state in which the upper end opening H of the side wall portion 11 is closed by the portion 21, that is, in a state in which the outer peripheral edge portion of the lid main body portion 21 is placed on the inner extension portion 14, the outer peripheral edge portion It will be in the state of being sandwiched between the extension portions 14. As a result, the lid 20 is in a state in which the movement in the vertical direction is completely or substantially completely restricted, and is thus attached to the box body 10 in a stable state.

  As described above, in the packaging box 1 according to the present embodiment, the lid body portion 21 is mounted on the internal extension portion 14 in the side wall portion 11 when the lid body 20 closes the upper end opening H of the side wall portion 11. Therefore, the lid 20 is not exposed on the outer periphery of the packaging box 1 (box body 10). As a result, the packaging box 1 can wrap the article P in a good-looking and novel manner without forming a step or the like on the outer periphery due to the presence of the lid 20.

  And, as described above, with the lid 20 closing the upper end opening H of the box body 10, the outer peripheral edge of the lid body 21 faces the upper end protrusion 13 on the upper side. When the article P accommodated by carrying the packaging box 1 is moved, for example, when an upward force (force to push up the lid body 20) acts on the lid body 20 from within the side wall portion 11, The outer peripheral edge of the lid main body 21 is locked to the opposing upper end protrusion 13, thereby preventing the lid 20 from being inadvertently detached.

  On the other hand, when the user intentionally holds the gripping portion 22 of the lid 20 and pulls up the lid 20, the outer peripheral edge of the lid main body 21 is deformed and gets over the upper end protrusion 13. The lid 20 can be removed.

  As described above, the packaging box 1 according to the present embodiment includes a box body 10 having a side wall portion 11 formed in an annular shape and a bottom portion 12 that closes a lower end opening of the side wall portion 11, and an upper end portion of the side wall portion 11. In the packaging box 1 including the lid 20 configured to be able to close the opening H, the box body 10 includes an upper end protruding portion 13 that protrudes inward from the entire inner periphery of the upper end portion of the side wall portion 11 or from a plurality of locations. And the inner extension part 14 extending inwardly from the entire inner periphery of the side wall part 11 or a plurality of locations at a position below the upper end protruding part 13, and the lid body 20 is an upper end part of the side wall part 11. A lid main body portion 21 formed of a sheet material which is formed so as to be able to close the opening H and whose outer peripheral edge portion is deformable; and a gripping portion 22 extending to the upper surface side of the lid main body portion 21; The lid body 21 is placed on the inner extension 14 within the side wall 11 at the outer peripheral edge. In addition to being able to oppose the upper end protrusion 13, the appearance can be improved and the lid 20 is not affected regardless of the height of the box body 10 that houses the article P. It is possible to achieve an excellent effect that it can be surely prevented from coming off.

  Moreover, since the said upper end protrusion part 13 is formed in the packaging box 1 which concerns on this embodiment by curling the upper end part of the side wall part 11 inside, the side wall part 11 and the upper end protrusion part 13 are integrated. It is formed, and the strength that can sufficiently withstand the force generated when the outer peripheral edge portion of the lid main body portion 21 rides on the upper end protruding portion 13 can be obtained.

  Furthermore, the packaging box 1 according to the present embodiment is provided with the upper end protruding portion 13 and the inner extending portion 14 over the entire circumference of the side wall portion 11, so that the upper end opening H of the side wall portion 11 is covered with the lid 20. When the cover is closed, the entire periphery of the outer peripheral edge of the lid main body 21 is received by the internal extension 14 and stable mounting is possible. In addition, when the lid 20 is about to move upward, the entire periphery of the outer peripheral edge of the lid body 21 is received by the upper end protrusion 13, and the lid 20 can be reliably prevented from falling off. .

  And the packaging box 1 which concerns on this embodiment is the state which closed the upper-end part opening H of the side wall part 11 with the cover body 20, and the internal extension part 14 has the outer-periphery edge part of the cover main-body part 21 with the upper-end protrusion part 13. FIG. Since the lid body 20 is arranged so as to be sandwiched, the lid body 20 does not move in the vertical direction when the lid body 20 closes the upper end opening H of the side wall portion 11. It can be attached and the appearance can be improved.

  In addition, this invention is not limited to the said embodiment, Of course, a various change can be added in the range which does not deviate from the summary of this invention.

  In the above embodiment, the rectangular side wall material 11 is rounded to form the cylindrical side wall portion 11. However, the present invention is not limited to this. For example, the side wall portion 11 is made of a paper material as in this embodiment. In the case of being formed in a cylindrical shape, the cylindrical paper tube may be cut into a required length in the axial direction to form the side wall portion 11.

  In the said embodiment, although the side wall part 11 was formed in cylindrical shape, the form of the side wall part 11 is not limited to this, For example, the side wall part 11 is made into an annular | circular shape, ie, a polygonal cylinder shape (frame shape). Of course, it may be formed. Therefore, the box body 10 is not limited to the one formed by connecting the side wall portion 11 and the bottom portion 12 formed of different members. For example, the box main body 10 is a polygonal shape (mainly a square shape) in plan view that becomes the bottom portion 12. It may be formed by bending a developing sheet in which a rectangular region serving as the side wall portion 11 is extended at each end edge defining the region. Even in this case, if the upper end protruding portion 13 is provided at the upper end portion of the side wall portion 11 and the internal extension portion 14 is provided at a position below the upper end protruding portion 13, the same operations and effects as in the above embodiment can be achieved.

  In the above embodiment, the gripping portion 22 is formed integrally with the lid main body portion 21 by cutting and raising a part of one sheet material. However, the present invention is not limited to this. You may make it connect the holding part 22 comprised with another member to the upper surface of the part 21. FIG.

  In the said embodiment, the upper end protrusion part 13 and the internal extension part 14 were provided over the perimeter of the inner periphery of the side wall part 11, ie, the upper end protrusion part 13 and the internal extension part 14 were cyclic | annular (doughnut shape). However, the present invention is not limited to this. For example, at least one of the upper end protruding portion 13 and the inner extending portion 14 is provided in an intermittent arrangement in the circumferential direction of the side wall portion 11. Also good. That is, a plurality of upper end protrusions 13 are provided intermittently (at intervals) in the circumferential direction of the side wall part 11, while the internal extension 14 is formed in an annular shape as in the above embodiment, or the upper end protrusions 13 may be formed in an annular shape as in the above embodiment, while a plurality of internal extending portions 14 may be provided intermittently (with a gap) in the circumferential direction of the side wall portion 11. Moreover, you may provide both the upper end protrusion part 13 and the internal extension part 14 intermittently (with a space | interval) in the circumferential direction of the side wall part 11. And when providing both the upper end protrusion part 13 and the internal extension part 14 intermittently in the circumferential direction of the side wall part 11 in this way (with a space | interval), it is necessarily limited to the arrangement which both faced. For example, the upper end protruding portion 13 and the internal extension portion 14 may be arranged so as to be shifted in the circumferential direction.

  In the above embodiment, the upper end protrusion 13 is formed by rounding (curling) the upper end of the side wall 11 (the end of the sheet material constituting the side wall 11). For example, similar to the internal extension portion 14, the upper end protruding portion 13 is formed of a separate member from the sheet material that becomes the side wall portion 11, and is connected to the side wall portion 11. The upper end protrusion 13 may be used. Further, the upper end protruding portion 13 is not limited to the one formed at the upper end edge of the side wall portion 11, and may be provided, for example, so as to be positioned below the upper end edge of the side wall portion 11. That is, the upper end protruding portion 13 may be disposed at a position deeper than the upper end edge of the side wall portion 11 within a range in which the appearance is good.

  In the above embodiment, the box body 10 and the lid body 20 are formed from sheet-like paper material (thick paper). However, the present invention is not limited to this. For example, both or one of them is used. Of course, it may be formed of a resin sheet.

  In the above embodiment, the entire lid body 21 is made of the same material on the assumption that the outer peripheral edge of the lid body 21 of the lid 20 can be deformed. However, the present invention is limited to this. For example, only the outer peripheral edge of the lid 20 main body may be formed of a deformable material (sheet material), and the portion inside the outer peripheral edge may be formed of a non-deformable material. .

  In the above embodiment, when the upper end opening H of the side wall portion 11 is closed by the lid body 20, the outer peripheral edge portion of the lid body 20 (lid body portion 21) becomes the inner extension portion 14 and the upper end protruding portion 13. However, the present invention is not limited to this. For example, the interval between the upper end protrusion 13 and the internal extension 14 is set wider than the thickness of the outer peripheral edge of the lid body 21. When the upper end opening H of the side wall portion 11 is closed with the lid body 20, the outer peripheral edge portion of the lid main body portion 21 is not sandwiched between the upper end protruding portion 13 and the inner extension portion 14, and the inner extension portion 14. You may make it be in the state put on. Even if it does in this way, since the outer peripheral edge part of the lid body part 21 is locked to the upper end protrusion part 13 even if the lid body 20 tries to move upward, the lid body 20 is prevented from being accidentally detached. can do. However, considering the mounting stability of the lid 20, the outer peripheral edge of the lid body 21 is sandwiched between the upper end protruding portion 13 and the internal extension 14 as in the above embodiment. It is preferable to do.

  In the above embodiment, the outer peripheral surface of the box body 10 (side wall portion 11) and the upper surface of the lid body 20 (lid body portion 21) are decorated by printing or attaching decorative paper. Of course, the material (sheet material) constituting these materials may be exposed on the surface.
