BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap to be attached to a mouth of a container, and more particularly to a cap for separating and recovering a container to be removed by using a bottle opener.

[0002]

2. Description of the Related Art Conventionally, a synthetic resin cap to be attached to the mouth of a container has been widely used. The mechanism by which the cap seals the mouth of the container is well known, so illustration and detailed description are omitted. It has a blocking wall for blocking the passage of articles, and has a projection formed on the inner surface of the cylindrical wall so as to be in pressure contact with an annular recess formed on the outer periphery of the mouth. Since such a cap is attached by a stopper when the cap is attached, it is widely used because the attachment process is easy. The above-mentioned situation is the same also in the inner plug type cap having the outer lid which is currently widely used.

[0003]

However, all of the above conventional caps have the following problems. That is, consumers consume the contents of a container and dispose of the container. Discarded containers are collected and recycled as resources again. In this case, the container and the cap attached thereto are separated due to the difference in the material. However, in this case, the cap cannot be easily removed because the cap is in press-fit engagement with the concave ridge of the container mouth by the ridge as described above. The present invention has been made to solve such a problem, and its purpose is to easily install it in the form of a stopper when it is attached to the mouth of a container, and it is very easy to collect the container from the container. It is an object of the present invention to provide a detachable use separation collection cap that can be removed.

[0004]

In order to achieve the above object, the present invention will be described. It is made of a synthetic resin and has a main body 3 of a cap having a cylindrical wall 1 and a blocking wall 2; formed on an inner surface of the cylindrical wall 1, A ridge 4 that presses and engages a concave ridge formed on the outer periphery of the mouth of the container; a part 5 of the lower end of the cylindrical wall 1 that is formed upward; A downward projection 6 protruding from the bottom projection 6; formed on both sides of the downward projection 6 so as to bend in a bay shape so that the lower part becomes concave, and to reach above the tip part 7 of the downward projection 6;
A stopper for use and separation and collection comprising a cut-out portion at both ends continuous with the cut-out portion.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The cylindrical wall 1 has a thin film 9 which extends over both the cutout 5 and the cutouts 8, 8 which are continuous with the cutout 5 and is pressed against the outer periphery of the mouth of the container. This is a separate collection cap for bottle opener. The cap body 3 is formed as an inner plug, an inner cylinder 10 is provided inside the cylinder wall 1 for pressing against the inner surface of the mouth of the container, and the cut-off wall 2 is formed by a tear groove 11. Tearing part 1 having member 12

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 to 4, reference numeral 3 denotes a main body of a cap made of a synthetic resin, for example, polyethylene, as an example. Reference numeral 1 denotes a cylindrical wall which has a ridge 4 which is brought into pressure contact with the outer periphery of the mouth portion 20 and which is pressed into engagement with a concave ridge 21 formed in the mouth portion 20. Reference numeral 2 denotes a blocking wall for blocking the passage of the storage items (not shown) in the container 19. Reference numeral 5 denotes a notch-shaped notch formed at a part of the lower end of the cylindrical wall 1, and a downward projection 6 is formed on an upper portion thereof, and a horizontal portion 22 is formed at a tip 7 of the projection 6. . On both sides of the projection 6, the both ends lacking portion 8, which bends in a bay shape so that the lower portion becomes concave, reaches above the tip portion 7 of the downward projection 6, and is continuous with the lacking portion 5, 8 are formed.

[0007] Next, reference numeral 9 denotes a thin film which is formed so as to extend over both the cutout portion 5 and both end cutout portions 8, 8 which are continuous with the cutout portion 5, and is continuous with the inner surface of the cutout wall 1. It is formed. Accordingly, the thin film 9 is brought into contact with the outer surface of the mouth 20 when the cap is attached to the mouth 20 of the container 19. As a result, the outer peripheral surface of the opening 20 is closed by the lacking portion 5 and the both end missing portions 8 and 8.

Next, the main body 3 of the cap was formed as an inner plug as shown in FIGS. An inner cylinder 10 is provided on the inner side of the cylindrical wall 1 so as to press against the inner surface of the mouth 20 of the container 19. Reference numeral 23 denotes an upper wall, and the upper wall 23, the cylindrical wall 1, and the inner cylinder 10 form a holding portion 24 for pressing and holding the opening 20 from inside and outside. Next, reference numeral 11 denotes an endless fissure formed in the blocking wall 2. A tearing portion 13 is formed inside the fissure 11 and a pull-ring-like tearing member 12 is provided on the upper part thereof. Next, as shown in FIG. 1, a filling cylinder 14 is formed on the outside of the tearing portion 13 of the blocking wall 2, and one side 15 of the filling cylinder 14 corresponding to the missing portion 5 is connected to the other side 16. It is formed in a thin portion 17 that is thinner than the other. The thin portion 17 is formed over the circumferential direction of the injection tube 14 and is formed to be easily bent inward. This configuration is similar to that shown in FIGS.
Put the stopper 25 on the body 3 of this cap attached to
When removing the main body 3 of the cap from the mouth portion 20, the thinner portion 17 is compressed and deformed inward by the stopper 25, whereby the stopper 25 can be applied. In addition, since it is usually formed to be particularly thin, it is possible to improve the so-called breakage of the droplet when the liquid is poured out as a injection cylinder. Reference numeral 30 denotes a hook that is hooked when the outer lid 35 is closed.

Next, the opening of the cap using the stopper will be described. First, as shown in FIGS. 6 to 8, the thin portion 17 of the injection tube 14 is pressed inward by the end portion 26 of the stopper 25, and is pressed inward and deformed as shown in FIG. 8. In this case, since the thin portion 17 of the injection tube 14 is formed particularly thin, it is easily bent inward and deformed. Therefore, the upper end portion 28 of the locking portion 27 of the bottle opener 25 is hung on the upper wall 23 in this state. Then, the lower end portion 29 of the locking portion 27 is hung on the distal end portion 7 of the downward projection 6 while maintaining that state, as shown in FIG. Next, the bottle opener 25 is further rotated in the direction of arrow A25 as shown in FIG. Then, in this case, the bottle opener 25 has the upper end portion 28 serving as a fulcrum, the grip portion 31 serving as a force point, and the lower end portion 29 serving as a lever, so that the cylindrical wall 1 of the cap is bent outward. As a result, as shown in FIG. 9, the ridge 4 of the cylindrical wall 1 of the cap is effectively moved away from the concave ridge 21 of the container 20 and moved upward.

Further, in this case, on both sides of the downward projection 6, both ends lacking portions 8, which are bent in a bay shape so that the lower portion becomes concave, and are formed above the distal end portion 7 of the downward projection 6, 8, the ridges 4, the concave ridges 21
When moving over the upper annular projection 32, the cylindrical wall 1 can easily and easily have a larger diameter with a relatively small force, and can move over the annular projection 32. Also, in this case, a thin film 9 is formed over both the above-mentioned lacking portion 5 and the both-ends missing portions 8, 8, whereby the mouth 2 of this portion is formed.
When the cap 7 is removed, the tip 7 of the downward projection 6 is pushed obliquely upward by the stopper 25 when removing the cap.
As shown in FIG.
, A downward stress 6 is generated, whereby the downward projection 6 is bent outward, whereby it is possible to prevent the plastic deformation after the elastic deformation and the removal of the downward protrusion 6 from becoming difficult. Further, even when plastic deformation does not occur, the thin film 9 is provided so that the pushing force F is dispersed around by the elastic deformation that is bent outwardly of the downward projection 6 and it is difficult to remove the film. This can be prevented for the same reason. That is, the provision of the thin film 9 in the lacking portion 5 can prevent large elastic deformation of the downward projection 6, so that when a force is applied to the bottle opener 25, it can be immediately refreshedly removed. The explanation of this operation is as described above.
The thin portion 17 is pressed by the end portion 26 of the stopper 25,
Although the method of deforming has been described, this is merely an example, and the thin portion 17 is pressed inward with a hand having no bottle opener 25 in advance and deformed. May be hung on the upper part of the upper wall 23 and the tip part 7 of the downward projection 6, and may be pulled out from the mouth 20 in this manner. A missing portion 5 of the cylindrical wall 1
And the downward projection 6 therein and the thin portion 17 of the cylindrical wall 1
Alternatively, as shown in FIGS. 1 and 6, the weakening line 18 and the like of the injection cylinder 14 are all formed on the opposite side of the outer lid 35.
The outer lid 35 includes a main hinge 33 and a sub hinge 34 as described later.
Therefore, when the outer lid 35 is opened and the content liquid (not shown) in the container 19 is poured out by opening the outer lid 35 and holding the open state and the closed state by themselves. This is usually performed with the outer lid 35 facing upward. This is because when the outer lid 35 is in the lower position, the outer lid 35 hinders liquid injection. When the content liquid is poured with the outer lid 35 facing upward as described above, the liquid to be poured is discharged from the thin portion 17 of the injection tube 14, and the liquid can be more preferably drained due to the thin wall. This also applies to a case where a weakening line 18 described later is formed. That is, the thin tube 17 having the thin portion 17 and the weakening line 18 usually serves as a syringe 14 for improving drainage, and when the cap is removed from the mouth portion 20, it easily breaks or deforms inward. This allows
The stopper 25 can be hung on this cap.

Next, in FIG. 5, a plurality of weakening lines 18, 18 are formed in a vertical direction on one side 15 of the injection tube 14 corresponding to the lacking portion 5, in a thin groove shape. Although not shown, the weakening lines 18 and 18 are formed such that one side 15 of the injection tube 14 is thinner than the other side 16 as described above.
7 may not be formed, or alternatively, as described above, the one side 15 may be thinner than the other side 16.
It may be formed when it is formed in.
The weakening lines 18 and 18 are also provided so that the one side 15 is pressed inward by a hand or a bottle opener to be broken or deformed so that the bottle opener 25 can be hung. When the cap body 3 is removed, the cap is pressed inward by the hand or the bottle opener 25 to break, compress, or deform.

Next, as described above, since the distal end portion 7 of the downward projection 6 is formed in the horizontal portion 22, when the distal end 7 is pushed upward in accordance with the locking portion 27 of the bottle opener 25,
The left and right ends can be pushed up evenly, so that the force can be evenly applied to the both end notches 8, 8 and the end notches 8, 8 are each bent in a bay shape so that the upper part is concave. Since this portion can be easily spread right and left, the ridges 4 formed on the cylindrical wall 1 can be easily removed from the cylindrical wall 1 when the annular ridges 32 on the upper part of the concave ridges 21 cross. Can be smoothly expanded in the circumferential direction. Therefore, it is possible to easily get over the annular projection 32. For this reason, removal of the cap main body 3 from the container can be facilitated.

Next, as shown in FIGS. 1 and 4, the main body 3 of the cap has an outer lid 35 integrally formed with a hinge 31. The hinge 31 is formed by a main hinge 33 at the center and sub hinges 34 provided on both sides thereof. The main hinge 33 is a bent-type hinge, and the sub-hinge 34 is formed in a substantially sine curve or substantially rectangular pulse shape on the side surface, thereby being formed to have elasticity. Then, the outer lid 35 is fixed by the hinges 33 and 34.
It has a self-holding function in both open and closed states. When a consumer or the like uses the cap body 3 thus formed, the outer lid 35 is opened, the tearing member 12 is pulled upward, the tearing portion 13 is torn from the tearing groove 11, and an opening is formed therein. To use. Then, the contents of the container are consumed, and the container 19 is collected by the collecting company and the container 3 and the main body 3 of the cap.
The operation of removing the main body 3 of the cap from the container 19 during the separation is performed as described above.

The lower end portion 29 of the stopper 27 of the bottle opener 25 is hooked on the distal end portion 7 by forming the both end missing portions 8 and 8 above the distal end portion 7 of the downward projection 6, and Upper end 2
By hanging the stopper 8 on the upper wall 23 and rotating the stopper 25 obliquely upward, the ridge 4 of the cylindrical wall 1 comes out of the concave ridge of the container and rides on the annular protrusion above the concave ridge. In this case, the above-mentioned both end missing portions 8, 8 formed by bending into a bay shape so that the lower portion becomes concave, are easily deformed so as to open the bay shape by the shape thereof. It is easily and automatically enlarged in the circumferential direction, so that the ridge 4 can easily pass over the annular ridge. The cap can thus be easily removed from the mouth of the container. According to the second aspect of the present invention, as described above, the thin film 9 extends over the lacking portion 5 and the lacking portions 8 at both ends.

11 is pushed up obliquely upward by the stopper 25, FIG.
As shown in (1), a tensile stress f is generated in the thin film 9 with respect to the pushing force F, whereby the downward projection 6 is prevented from being bent outward and being plastically deformed after elastic deformation, making it difficult to remove. be able to. Also, the thin film 9 is provided to prevent the pushing force F from being dispersed around by the elastic deformation that is bent outward of the downward projection 6 even when the plastic deformation does not occur, thereby causing a frustration that cannot be easily removed. For the same reason. That is, the provision of the thin film 9 in the lacking portion 5 can prevent large downward deformation of the downward projection 6, so that when a force is applied to the stopper 25, the stopper can be removed immediately and immediately.

According to the third aspect of the present invention, since the cap body 3 is formed as an inner stopper, an inner stopper which can be easily removed from the container by using a stopper can be provided. In addition, when the tube is removed from the container, the inner wall can be provided so that the cylindrical wall 1 automatically expands in the circumferential direction and is easily removed. The invention according to claim 4 is the injection cylinder 14
The one side 15 corresponding to the lacking part 5 is formed in the thin part 17 which is thinner than the other side 16 so that when the cap body 3 is removed from the container using the bottle opener, this part is pressed inward. And the cap body 3 can be opened and easily removed. Moreover, when used, the liquid can be effectively drained at the time of pouring, particularly as a thin-walled pouring cylinder 14.

According to a fifth aspect of the present invention, the missing portion 5
By forming a plurality of weakening lines 18 in the vertical direction on one side 15 corresponding to the weakening lines 18,
