Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used by attaching to the mouth of a container such as a bottle with a stopper, and the container can be easily removed from the container when the container is collected. The present invention relates to a recovery hinge cap.

[0002]

2. Description of the Related Art Conventionally, a cap of a container generally attached by a stopper is formed of a synthetic resin. In this case, since the cap is softly and tightly closed at the mouth of the container, a synthetic resin having relatively flexibility, for example, polyethylene is used. The cap made of polyethylene is close to the mouth of the container due to its flexibility and therefore exhibits a high hermeticity.

[0003]

However, such a cap has the following problems. In this case, after the contents of the container are consumed, the cap is removed when the container is collected. Normally, these caps are in pressure contact with the mouth of the container and are provided with a notch or the like, which is not shown in the drawings, for notching the stopper so that it can be easily removed from the container. However, when the stopper is opened and the stopper is removed, the stopper for catching the stopper is deformed due to the flexibility of polyethylene, which is the material of the stopper. In the limit of their deformation, a reaction force is finally generated to perform the opening operation. In other words, it gives a frustration that the user cannot immediately remove the bottle even when the stopper is removed.

[0004] For this reason, when the container is removed from the container, it is desired to have a rigidity that immediately generates a reaction force against the opening of the container. Thus, the cap of the container which is attached by tapping and removed by opening the bottle has been required to have conflicting and contradictory functions of flexibility and rigidity. And such a problem was not easily solved. The present invention has been made in order to solve the above-described problems, and when attached to the container mouth, it is possible to increase the hermeticity by tightly tightly contacting the mouth and using a bottle opener. It is an object of the present invention to provide a separating / collecting hinge cap for use with a bottle opener, which exhibits rigidity when removed from the container, immediately generates a reaction force to the operation of the bottle opener, and can be removed immediately.

[0005]

According to the present invention which solves the above-mentioned problems, it is made of a relatively flexible synthetic resin, and comprises a cylindrical portion and an upper wall which are engaged and pressed against a container mouth portion. The wall has a score that defines an opening forming portion, and an inner lid having a pouring tube outside the score, a hooking portion that engages with a later-described outer lid formed on the inner lid, and an outer portion of the cylindrical portion. Having an outer cylinder pressed against and a lid hinged to the outer cylinder,
Having an engaging portion to be hooked on the engaging portion, comprising an outer lid formed of a synthetic resin having higher rigidity than the synthetic resin of the inner lid, outside the outer cylinder, having a higher rigidity than the inner lid. A separate recovery hinge cap for use with a bottle opener, wherein a rigid projection for locking the bottle opener is provided integrally. In addition, the outer cylinder is the separate recovery hinge cap for use with the bottle opener, which has a cutout corresponding to the rigid projection at the lower end of the outer cylinder. The rigid protrusion is a separate recovery hinge cap for use with the bottle opener provided below the hinge.
In addition, the rigid projection is the separation-collection hinge cap for use with the bottle opener provided in a state where a part thereof intersects and contacts with the hinge in a plan view and a part does not intersect with the hinge. or,
The rigid projection is the separation-collection hinge cap for use with the bottle opener provided outside the outer cylinder and at a position not intersecting with the hinge in plan view. In addition, the rigid projection is the separating / collecting hinge cap for use with the bottle opener formed in a plurality of ribs in the vertical direction. The lower end of the rigid projection is the bottle-collecting / separation / recovery hinge cap having a height up to 15 mm or more to the upper end of the lid when the lid is closed. In addition, the lower portion of the rigid projection is the separation-collecting hinge cap for use with the bottle opener, which has a slope that becomes thinner toward the lower end and toward the outside in the radial direction. or,
The dispensing cylinder is a separate recovery hinge cap for use with the bottle opener, in which a portion corresponding to the rigid protrusion is notched. In addition, the spouting cylinder is a separating / collecting hinge cap for use with the bottle opener, wherein the portion corresponding to the rigid projection is formed to be thin so that it can be easily deformed by bottle opener. The dispensing cylinder is a separate collection hinge cap for use with a bottle opener having a plurality of vertical weakening lines at portions corresponding to the rigid protrusions.

[0006]

According to the first aspect of the present invention, as described above, the inner lid made of a relatively flexible synthetic resin is flexibly in close contact with the mouth of the container, press-contacted and sealed, and the contents of the container. When collecting the container after consumption of the article, the inner lid is provided with a synthetic resin outer lid having higher rigidity than the inner lid, and the outer lid is engaged with the inner lid, and The outer cylinder of the outer lid is in pressure contact with the cylinder. A rigid projection that is higher in rigidity than the inner lid and that locks the stopper is integrally formed on the outer side of the outer cylinder of the outer lid. And the rigid projections are not deformed due to the high rigidity, and the outer cylinder provided with the rigid projections is also not deformed due to the high rigidity, and immediately exhibits a reaction force due to the rigidity of both, so that the entire cap is immediately You can remove it gracefully. This also comes off integrally due to the pressure contact between the cylinder and the outer cylinder.

That is, each part is deformed due to insufficient rigidity, and it is possible to eliminate the frustration that the cap does not come off without generating a sufficient reaction force.

According to the second aspect of the present invention, since the bottle opener can be locked by using both the rigid protrusion and the lacking portion, the stopper can be used only in the case of the rigid protrusion. In comparison, the amount of outward protrusion of the rigid projection can be reduced, the appearance can be made compact and smart, and the commercial value can be increased. Also, rigid resin material can be saved.

According to the third aspect of the present invention, when the cap is illegally removed from the container, the hinge becomes an obstacle and the stopper cannot be hung on the rigid projection. Therefore, illegal opening of the container equipped with the cap can be prevented. When the rigid projection is to be unplugged, the hinge can be easily broken by holding and twisting the lid, so that the lid is removed in this way, and then the stopper is removed from the rigid projection. I hang it.

According to the fourth aspect of the present invention, the rigid projection is provided in such a manner that a part of the rigid projection intersects and contacts the hinge and a part of the rigid projection does not intersect with the hinge in plan view. Unless the hinge is broken and the lid is removed, the bottle opener cannot be hung on the rigid projection, so that unauthorized opening of the container equipped with this cap can be prevented. Also, the rigid projection is in a state where a part thereof crosses and touches the hinge in a horizontal view, and the hinge is a so-called snap-type hinge having three portions, that is, an elastic hinge at the center of the normal hinge on both sides. It is possible to avoid under the elastic hinge part in the central part. Due to its function, this elastic hinge cannot be formed by contacting the rigid projection with the rigid projection. For this reason, if these are formed at an interval above and below, the rigid projection forms an undercut portion, and therefore cannot be removed as it is. The mold must be split. However, as described above, since the rigid projection is provided under one of the left and right normal hinges, avoiding the area under the elastic hinge at the center, the mold does not have to be split and the mold is formed. Can be simplified. Further, the rigid projection can be strongly held at the portion closest to the hinge by applying a finger to the rigid projection as shown in FIG. 9 when twisting the lid, and grasping the outer cylinder in cooperation with other fingers. Therefore, it is possible to easily twist off the lid.

According to the fifth aspect of the present invention, the rigid projection can be unplugged in the open state of the lid, and the trouble of removing the lid can be eliminated. Further, since the rigid projection does not intersect with the hinge in plan view, the mold does not need to be split, and the mold can be formed easily. Further, when the outer cylinder is gripped when the lid is to be cut off, the finger can be put on the rigid projection, so that the above-mentioned twisting can be facilitated.

According to the sixth aspect of the present invention, because of the rigidity, even if it is formed into a plurality of ribs instead of being formed in a plate shape, a sufficient reaction force is exhibited in opening the bottle. Can perform the opening operation, thereby saving the synthetic resin material.
Further, by providing the snap type hinge having three hinge portions in contact with the normal hinges at both ends, the hinge at that portion can be reinforced. In addition, the rib-shaped rigid projections can be provided below the elastic hinges on both sides of the snap-type hinges, avoiding the elastic hinges at the center, and can be provided below the elastic hinges. Since the mold does not have to be divided, the mold formation can be simplified.

The invention according to claim 7 is configured as described above,
By setting the height of the lower end of the rigid projection to the upper end of the lid to be 15 mm or more with the lid closed, as shown in FIG. It is not possible to apply the removal inside the rigid protrusion and the upper surface of the lid, that is, in a state in which the stopper removal operation is performed. That is, even if the stopper can be hooked on the rigid projection, the upper part of the stopper does not reach the inside of the upper surface of the lid, and the stopper becomes almost vertical, so that the stopper can not be removed. Therefore, if the rigid projection is below the hinge or a part of the rigid projection intersects the hinge in plan view, it is not possible to use the bottle opener, so that unauthorized opening of the cap can be prevented. Usually, the distance between the upper and lower portions of a general bottle opener that bites a stopper, a lid or the like is less than 15 mm.

According to the eighth aspect of the present invention, since the lower portion of the rigid projection is formed to have a thin slope, the stopper can be easily inserted, and the thin projection is thin. Nevertheless, since the rigidity is high, no deformation occurs even if a force is applied by the opening operation, and a reaction force is immediately generated, so that the opening operation can be surely performed.

According to the ninth aspect of the present invention, as described above, the upper portion of the bottle opener can reach the inside of the pouring cylinder in the radial direction, and the bottle opener can be inclined horizontally. , Can be opened. If there is no notch in the dispensing cylinder, the bottle opener will be nearly vertical,
The opening operation is difficult.

According to a tenth aspect of the present invention, the upper portion of the bottle opener presses a portion corresponding to the rigid projection of the spout cylinder so that it can be easily deformed obliquely downward. Thus, the bottle opener can be formed in a form inclined in the horizontal direction, and the bottle opener operation can be facilitated. In this case, since the rigid projection has a high rigidity and immediately generates a reaction force without being deformed, the thin portion can be easily deformed.

According to the eleventh aspect of the present invention, when the portion corresponding to the rigid projection of the dispensing cylinder is pressed obliquely downward by the upper portion of the stopper, a plurality of weakening lines may be broken. Or, it is deformed at the portion of each weakening line, and is deformed obliquely downward. In this manner, the bottle opener can be set to the operation state with the bottle opener facing obliquely downward.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 to 5, reference numeral 1 denotes an inner lid, which is formed of a synthetic resin, for example, polyethylene which is relatively flexible and which is easily in close contact with a container mouth. The inner lid 1 is formed by a cylindrical portion 4 that engages with and presses against the outer periphery of the opening 3 of the container 2 and an upper wall 5 that blocks the passage of the liquid (not shown) in the container 2. A thin score 6 forming an opening is formed. Reference numeral 7 denotes a discharging cylinder. In addition, a concave streak 8 is formed on the outer periphery of the mouth portion 3 and the cylindrical portion 4 is formed.
A ridge 9 is provided on the inner surface for press-fitting engagement with the concave ridge 8. Reference numeral 10 denotes a portion provided on the upper wall 3 for engaging with an outer lid described later.

Reference numeral 11 denotes an outer lid, which is formed of a synthetic resin having higher rigidity than the synthetic resin forming the inner lid, for example, polycarbonate, ABS resin, polypropylene, or the like. , And a lid 14 integrally provided with a hinge 13 to the outer cylinder 12. Reference numeral 15 denotes a hook provided on the outer lid 11 for hooking with the hook 10. 1
Reference numeral 6 denotes a tearing member for tearing the score 6, and reference numeral 17 denotes an inner cylinder, which is pressed against the inner surface of the mouth portion 3.

Reference numeral 18 denotes a rigid projection which is engaged with the bottle opener 19 (FIG. 6), and is provided on a part of the outer periphery of the outer cylinder 12 so as to protrude outward. The rigid projections 18 are formed with a higher rigidity than the synthetic resin forming the inner lid 1, and are practically not deformed at all even if the stopper 19 is locked and pulled upward, and therefore immediately. A reaction force is generated, which makes it difficult to open with the deformation and immediately opens the door immediately. In this case, the outer cylinder 12 also
Not deforming due to high rigidity cooperates with not deforming the rigid protrusion 18. Note that the hinge 13 is a so-called snap-type hinge composed of three parts as shown in FIG. 5, and a normal hinge 13a is formed on both sides, respectively (one normal hinge 13a is shown in the figure). An elastic hinge 13b that is bent downward and protrudes is provided at the center. The normal hinge 1
3a is bent at the center 13c in the longitudinal direction. The elastic hinge 13b is formed to project downward and to be elastically deformable. Usually, the outer lid 11 is injection-molded in the state shown in FIG. 5, and 32 is a parting line formed by an upper mold (not shown) that forms the upper part of the cap and a lower mold that forms the lower part. Rigid projection 18
Is located below the elastic hinge 13b, and in this case, it is not provided in contact with the elastic hinge 13b, but is provided at an interval in the vertical direction, so that an undercut portion is formed. In FIG. 5, molding is performed using a split mold that can be moved in the direction perpendicular to the paper surface.

Next, in the outer cylinder 12 corresponding to the lower end of the rigid projection 18, a notch-shaped notch 20 is formed as shown in FIGS. In addition, this missing part 20 may be a hole. By forming in this manner, the hooking depth of the stopper 19 can be increased, so that the amount of projection of the rigid projection 18 can be reduced accordingly. Therefore, the appearance can be made compact and smart, and the commercial value can be increased. next,
The rigid projection 18 is provided on the hinge 13 as shown in FIGS.
Formed below. With this configuration, if the cap is illegally opened, the lid 1 must be broken off from the hinge 13 and removed.
4 becomes an obstacle and the bottle opener 19 cannot be used, so that unauthorized opening can be prevented. Next, the rigid protrusion 18 shown in FIG. 7 is partially crossed and in contact with the hinge 13 in plan view, and partially not crossed.

Since the hinge 13 is constructed as described above, unless the lid 14 is removed, the lid 14 becomes an obstacle and the stopper 19 cannot be hung on the rigid projection 18.
Unauthorized opening can be prevented. Since the rigid projection 18 is provided under the hinge 13 below the central elastic hinge 13b, the rigid projection 18 is
Since it is formed in contact with a, an undercut portion does not occur in this portion, and the injection molding die does not have to be split, and the die formation can be simplified. In addition, the consumer consumes the contents of the container 2 and then collects the lid 1 when collecting the container.
When breaking the hinge 4 from the hinge 13, as shown in FIG. 9, a finger 21 is put on the rigid projection 18, the cap is gripped by another finger 22, and the lid 14 is twisted in the direction of arrow A <b> 14. 13 can be easily screwed off.
In this case, the finger 21 is connected to the rigid projection 18 near the hinge 13.
Since the cap holds down the cap, it is easy to apply a force, so that the hinge 13 can be easily twisted. Next, as shown in FIG.
It may be provided on the outer cylinder 12 other than the lower part of the hinge 13. This is provided, for example, in a direction perpendicular to a line connecting the hinge 13 and the center of the outer cylinder 12. By doing so, the bottle opener 19 can be hung in a state where the lid 14 is open, and the trouble of removing the lid 14 can be omitted. In addition, the rigid projection 18 can be formed so as not to generate an undercut portion, and the die can be formed easily because the die does not have to be split.

Next, as shown in FIG. 10, the rigid projections 18 are formed on a plurality of ribs 23 in the vertical direction. When formed in this manner, the ribs are formed in the up-down direction, and a stronger reaction force against the force of the bottle opener 19 can be exhibited. Also, the synthetic resin material can be saved. The rib-like rigid projections 18 are located under the elastic hinges 13b at the center of the snap-type hinge, and are provided on the both sides of the ordinary hinges 13a.
Since the rigid protrusion 18 does not need to form an undercut portion by being provided in contact with the lower part of the mold, the mold does not have to be split and the mold can be formed easily. In this case as well, in the case shown in FIG. 3, the lower end of the rigid projection 18 is formed to be convex downward. By forming in this way, it is possible to easily open the bottle. Next, as shown in FIG.
The height 26 up to the upper end 25 of the lid 14 when the lid 14 is closed is formed to be 15 mm or more. By forming in this manner, the normal opening is not performed as shown in FIG. 11, so that unauthorized opening can be prevented. In addition, the interval of the part which bites the plug, lid, etc. of a commercially available bottle opener is usually less than 15 mm as mentioned above.

The engaging portion 10 is provided on the upper wall 5, and the engaging portion 15 of the outer cylinder 12 is engaged with the engaging portion 10. On the other hand, the rigid projection 18 is provided near the lower end of the outer cylinder 12. As a result, the distance between the engaging portion 10 and the rigid protrusion 18 can be increased, so that the engaging portion 10 and the engaging portion 15
, And the inner lid 1 and the outer lid 11 can be integrally removed. As shown in FIGS. 1 and 2, the rigid projection 18 is formed so as to have an inclination 27 which becomes thinner toward the lower end and further outwardly in the radial direction. With this configuration, the stopper 19 can be easily hooked. In addition, since this portion is formed with high rigidity, even if it is thin, it does not deform or break when a force is applied by plugging, and immediately generates a reaction force, so that it functions reliably. Next, as shown in FIGS.
Is formed as a notch 28 at a portion corresponding to the rigid projection 18. By forming in this manner, as shown in FIG. 6, the upper part of the bottle opener 19 can be hung on the engaging portion 10 or the like, and the bottle opener 19 is tilted in the horizontal direction so that the bottle remover can be operated. Can be hung. When such a notch 28 is not formed, although not shown, the bottle opener 19 is in a nearly vertical state, which makes the bottle opening operation difficult.

Next, for the same reason, as shown in FIG.
9 was formed. By forming in this manner, when the thin portion 29 is pressed inward by the upper portion of the bottle opener 19 and obliquely downward, the thin portion 29 is easily deformed and pushed and bent. It is possible to make the state tilted more horizontally than the vertical direction, that is, a state where the bottle opening operation can be performed. For the same reason, the pouring cylinder 7 of the inner lid 1 shown in FIG. 13 also has a plurality of vertical weakening lines 30 formed at a portion corresponding to the rigid projection 18.
The weakening line 30 is pressed inward and obliquely downward by the upper part of the bottle opener 19 during this interval, so that it breaks or easily deforms obliquely downward and inward even if it does not break, so that the bottle opener 19 becomes vertical. The tilting state can be set to be closer to the horizontal state than the close state, and the stopper removal operation can be facilitated.

When a general user such as a consumer first opens the cap, the lid 14 is opened and the tearing member 16 is opened.
The score 6 is broken, the score 6 is broken, an opening is formed in the score 6, and contents (not shown) of the container 2 are poured out and used. After the consumption of the contents, when the container 2 is collected, the lid 14 is used as described above.
If the rigid protrusion 18 is not provided below the hinge 13 but is provided without crossing the hinge 13 in a plan view of the outer cylinder 12, the lid 14 is opened and the rigid protrusion 18 is removed. By using the notch 28 or the like of the pouring cylinder 7, a stopper 19 is hung on the engaging part 10 or the like, and the inclined state is more horizontal than the state close to vertical as described above. Remove the cap and collect the container.
