Description

  The present invention relates to a hinge cap removal structure that allows a hinge cap to be easily removed from a container after use, and in particular, a hinge cap removal structure that facilitates molding of the hinge cap and can be easily removed by anyone. About.

  Patent Documents 1 to 3 describe synthetic resin hinge caps that can be removed from a used container for separation and collection.

  The hinge cap described in Patent Literature 1 includes an outer wall having a score for skirt tearing and an inner wall having an engagement portion with a container neck, and the outer wall is expanded or removed outward at least on the hinge side. It is provided as possible. To remove the hinge cap from the container, grip the top lid and pull it outward or further downward to shear the weakening line called the score, then grip the top lid and pull outward. The cap is removed after the outer wall is cut off by breaking the bridge along the circumferential direction of the cap.

  The hinge cap of Patent Document 2 forms a first axial score extending from the upper end to the lower end or near the lower end at both ends of the hinge connecting portion of the outer wall, and at a position facing the first score of the inner wall. A second axial score from the lower end or near the lower end to at least the locking projection is formed. To remove this cap, after tearing the outer wall skirt tear score, the outer wall on the hinge side is expanded outward to release the restraint of the outer wall against the inner wall, and the container mouth and inner wall The engagement portion is loosened and removed.

The hinge cap described in Patent Document 3 is set so that the outer cylinder assembly strength with respect to the container mouth can be removed by a forceful pulling operation of the lid by hand, at a position facing the hinge, A first notch portion of the weakening portion is provided, and a second lacking portion of the weakening portion is provided at a position facing the connecting piece. To remove this cap from the container, hold the lid and pull it up, pulling the ring body while breaking the weakened part sequentially along the circumferential direction from the hinge side, all the weakened parts are broken and the ring body is connected After only the portion is connected to the outer cylinder, the lid is strongly pulled up and removed.

  Each of the hinge caps described in each patent document employs a structure in which the container fitting portion of the cap is formed with a double wall so that the weakened portion does not break during the stoppering. However, when the container fitting portion of the cap has a double wall structure, not only the mold design becomes complicated, but also the portion of the mold that forms the gap between the double walls tends to be damaged. There was also an inconvenience that caused a lot of trouble in maintenance.

  In addition, when filling the contents into the hinge cap, when filling noodle soup with the filling, for example, so-called HOT filling is performed in which the filling is filled at a high temperature of about 90 degrees Celsius. In this HOT filling, there is a step of applying cooling water to the outside of the container in order to cool the high-temperature filling. However, when the container fitting part of the cap is formed on the double wall, the cooling water enters the inside of the lid through the gap between the double walls, or between the container fitting part and the lid inside the lid. There was also a risk of cooling water entering. As a result, in the hinge cap having the double wall structure, there is a possibility that the cooling water that has entered the inside of the lid body from each gap remains, and mold is generated inside the lid body.

  Further, in the conventional hinge cap, since the double wall is cut off and then the cap is removed, this work requires a great deal of labor. For example, in Patent Document 1, first, the upper lid is gripped, and the skirt tear score is separated by pulling it outward or further downward. Subsequently, by gripping the upper lid and pulling it outward, the bridge along the circumferential direction of the cap is broken to separate the outer wall. Thereafter, the inner wall is spread outward, the engagement between the container neck and the engaging portion of the inner wall is released, and the cap body is removed. As described above, in Patent Document 1, the work of removing the cap requires a lot of labor, such as holding the cap many times and separating the score.

  To remove the hinge cap of Patent Document 2 from the container, first, the upper lid is pulled downward to break the first score, and then the upper lid is pulled upward to break the second score. Subsequently, the cap is finally obtained by breaking the third circumferential score provided on the lower end portions of the inner wall and the outer wall, the fourth axial score provided on the inner wall, and the fifth circumferential score. Can be removed. Thus, even in the cited document 2, much work is required for the work of removing the cap.

  Furthermore, in Patent Document 3, first, the lid body is gripped and pulled up, and the ring body is caused while the weakened portion is sequentially broken from the hinge side along the circumferential direction, and all the weakened portions are broken. Subsequently, after the ring body is connected to the outer cylinder only by the connecting portion, the outer cylinder is removed by forcibly pulling up the lid. As described above, since the outer cylinder is further forcibly removed after the weakened portion is broken, in Cited Document 3, a force for forcibly removing the outer cylinder is required at the same time as many efforts.

  As described above, in the conventional hinge cap, even if a score or weakened portion to be removed from the container is provided, it takes much time to remove the cap, and it has been difficult for a powerless person to remove the cap forcibly.

  Therefore, the present invention was created to solve the above-mentioned problems, and unlike conventional hinge caps, the fitting portion of the container is not made into a double structure, preventing unexpected breakage at the time of capping, and ineffective. It is an object of the present invention to provide a separation and disposal hinge cap that allows a person to easily remove the cap by a simple operation.

  The first means of the present invention includes a fitting cylinder body 10 having a fitting protrusion 15 fitted to an undercut P2 provided on the outer surface of the container P neck P1, and a hinge 20 on the fitting cylinder body 10. In the hinge cap having an upper lid 30 that is pivotably connected to the fitting cylinder body 10 and provided with a weakening line for separation on the fitting cylinder body 10, the fitting cylinder is adjacent to either one of the left and right ends of the hinge 20. A longitudinal weakening line 11 that cuts in the vertical direction from the upper end to the vicinity of the lower end of the main body 10 is provided, and a separation preventing portion 12 having the same thickness as the fitting cylinder main body 10 is provided at the lower end of the vertical weakening line 11. The lateral weakening line 13 is provided along the longitudinal direction of the hinge 20 from the upper end of the horizontal weakening line, and the auxiliary lateral weakening line 14 is provided in the opposite direction of the lateral weakening line 13 through the longitudinal weakening line 11.

  In the second means, the distal end portion of the lateral weakening line 13 is from the center position of the fitting cylinder body 10 to the virtual line S passing through the longitudinal center of the hinge 20 from the center position of the fitting cylinder body 10. It is formed at a position of 65 degrees.

  The longitudinally weak line 11 in the third means is at a position 40 degrees from the center position of the fitting cylinder body 10 with respect to the virtual line S passing through the longitudinal center of the hinge from the center position of the fitting cylinder body 10. Is formed.

  The longitudinal weak line 11 in the fourth means is at a position 40 degrees from the center position of the fitting cylinder body 10 with respect to the virtual line S passing through the longitudinal center portion of the hinge from the center position of the fitting cylinder body 10. At the same time, the tip of the auxiliary lateral weakening line 14 is formed at a position 65 degrees from the center position of the fitting cylinder body 10 with respect to the virtual line S.

  According to claim 1 of the present invention, a longitudinal weakening line 11 is provided that is close to either the left or right side of the hinge 20 and is separated in the vertical direction from the upper end of the fitting tube main body 10 to the vicinity of the lower end, and the lower end of the longitudinal weakening line 11 Since the separation preventing portion 12 having the same thickness as the fitting cylinder main body 10 is provided in the portion, it is possible to prevent unexpected breakage at the time of stoppering without making the fitting portion of the container a double structure. .

  Further, a separation preventing portion 12 having the same thickness as the fitting tube main body 10 is provided at the lower end portion of the longitudinal weakening line 11, and a lateral weakening line 13 is provided from the upper end portion of the longitudinal weakening line 11 along the longitudinal direction of the hinge 20. Therefore, when removing the cap of the present invention, the upper lid 30 is gripped and the upper end portion of the longitudinal weakening line 11 is separated so that the separation is prevented from the longitudinal weakening line 11 to the lateral weakening line 13 and at the same time the separation preventing portion 12 is easily separated. It is. If the upper lid 30 is pulled outward or slightly downward as it is, the entire lateral weakening line 13 is cut off.

  Further, since the auxiliary lateral weakening line 14 is provided in the opposite direction of the lateral weakening line 13 via the longitudinal weakening line 11, the upper lid 30 is lifted as it is, and the auxiliary lateral weakening line is raised as the fitting cylinder body 10 is lifted. 14 is cut off naturally. Then, the length sufficient to remove the fitting cylinder main body 10 is cut off, and the cap is easily removed from the neck portion P1 of the container P simply by lifting the upper lid 30 as it is. As a result, as a specific operation in the work of removing the cap of the present invention, it is a simple operation of simply grasping the upper cover 30 and separating it from the upper end of the longitudinal weakening line 11 and lifting the upper cover 30, and has a brute force. Even a weak person can easily remove it.

  According to claim 2 of the present invention, the distal end portion of the lateral weakening line 13 is located at the center position of the fitting cylinder body 10 with respect to the virtual line S passing through the longitudinal center portion of the hinge 20 from the center position of the fitting cylinder body 10. Therefore, the force for lifting the upper lid 30 can be transmitted to the optimum position for lifting the fitting cylinder body 10. That is, the length of the lateral weakening line 13 is cut to a position of 130 degrees in total on the left and right of the hinge 20, and this position is an optimal position for transmitting a force for lifting the fitting cylinder body 10. As described above, the lateral weakening line 13 is set at an optimal position for lifting the fitting cylinder body 10 fitted to the neck P1 of the container P.

  According to claim 3, the longitudinally weak line 11 is formed at a position 40 degrees from the center position of the fitting cylinder body 10 with respect to the virtual line S passing through the longitudinal center portion of the hinge from the center position of the fitting cylinder body 10. By doing so, when the upper lid 30 is gripped and separated from the upper end portion of the longitudinal weakening line 11, it can be most easily separated. Further, since the tip of the auxiliary lateral weakening line 14 is formed at a position of 65 degrees with respect to the virtual line S, when the lateral weakening line 13 and the auxiliary lateral weakening line 14 are separated, an undercut P2 Thus, the fitting protrusion 15 fitted to the detachable portion is disengaged in a wide range, and the removal work of the fitting cylinder body 10 can be simplified.

  Thus, according to the present invention, unlike conventional hinge caps, the fitting part of the container does not have a double structure, preventing unexpected breakage at the time of stoppering, and even a powerless person can easily remove the cap with a simple operation. It has an excellent effect that it can be easily removed.

  The best mode of the present invention is provided with a longitudinal weakening line 11 that is close to either the left or right side of the hinge 20 and is separated in the longitudinal direction from the upper end of the fitting cylinder body 10 to the vicinity of the lower end, and the lower end of the longitudinal weakening line 11. The separation preventing part 12 having the same thickness as the fitting cylinder main body 10 is provided in the part. A lateral weakening line 13 is provided along the longitudinal direction of the hinge 20 from the upper end of the longitudinal weakening line 11. An auxiliary lateral weakening line 14 is formed in the opposite direction of the lateral weakening line 13 via the longitudinal weakening line 11. The distal end portion of the lateral weakening line 13 and the distal end portion of the auxiliary lateral weakening line 14 are connected to the imaginary line S passing through the longitudinal center of the hinge 20 from the center position of the fitting tubular body 10. It is formed at a position of 65 degrees on each of the left and right sides from the center position. By forming the longitudinal weakening line 11 at a position 40 degrees from the center position of the fitting cylinder main body 10 with respect to the virtual line S, the initial purpose is achieved.

  The cap of the present invention is a hinge cap that is plugged into the neck P1 of the container P. This cap has a fitting cylinder main body 10, a hinge 20, and an upper lid 30 as basic components, and the upper lid 30 is pivotably connected to the fitting cylinder main body 10 via the hinge 20 (see FIG. 3).

  An inner ring 16 is formed on the fitting cylinder body 10 in the illustrated example (see FIG. 2). The inner ring 16 is inserted into the opening of the container P. A score 17 is formed inside the inner ring 16, and a tab 18 for breaking the score 17 is provided. By pulling the tab 18, the score 17 Is broken. Further, on the upper surface side of the inner ring 16, a dispensing cylinder 19 for dispensing the content liquid is formed so as to surround the score 17. The illustrated upper lid 30 includes a top plate 31 and side walls 32 depending from the periphery of the top plate 31. A ring-shaped projection 33 for sealing is formed downward from the inner surface of the top plate 31. When the upper lid 30 is closed, the ring-shaped protrusion 33 comes into close contact with the inner surface of the dispensing cylinder 19.

  The fitting cylinder main body 10 is a portion that fits to the outer surface of the neck portion P1, and a convex shape that is provided around the inner side surface of the fitting cylinder main body 10 in a concave undercut P2 that is provided around the outer surface of the neck portion P1. The fitting projection 15 is fitted (see FIGS. 2 and 5). The fitting cylinder main body 10 is provided with a weakening line for separation. There are three types of weakening lines: longitudinal weakening line 11, lateral weakening line 13, and auxiliary lateral weakening line 14 (see FIG. 3).

  The longitudinal weakening line 11 is provided so as to be close to either one of the left and right ends of the hinge 20 and to be separated in the longitudinal direction from the upper end to the vicinity of the lower end of the fitting cylinder body 10 (see FIG. 1). The illustrated longitudinal weakening line 11 has a groove shape and is arranged on the left side of the hinge 20 facing the fitting cylinder body 10 and is set at a position where it can be easily cut when the hinge 20 is gripped with the right hand. . Further, the setting position of the longitudinal weak line 11 is formed at a position 40 degrees from the center position of the fitting cylinder body 10 with respect to the virtual line S passing through the longitudinal center portion of the hinge from the center position of the fitting cylinder body 10. By doing so, it is set to an optimal position for gripping and separating the upper lid 30. That is, if the position where separation is started is too close to the hinge 20, the hinge 20 may be broken, and if the longitudinal weakening line 11 is too far from the hinge 20, a large force is required to start cutting. Therefore, the longitudinal weakening line 11 is set at an optimum position for gripping and separating the upper lid 30. Moreover, in the example of illustration, the auxiliary | assistant vertical weakening line 11A is provided in the opposite position through the hinge of the vertical weakening line 11 (refer FIG. 3). The auxiliary longitudinal weakening line 11A facilitates the work of grasping the upper lid 30 and separating the upper end portion of the longitudinal weakening line 11 so that the lateral weakening line 13 extending from the longitudinal weakening line 11 to the auxiliary longitudinal weakening line 11A can be easily made. It can be separated (see FIG. 5). Thereafter, when the upper lid 30 is pulled outward or slightly downward, the entire lateral weakening line 13 is cut off (see FIG. 6).

  A separation preventing portion 12 having the same thickness as that of the fitting cylinder main body 10 is provided at the lower end portion of the longitudinal weakening line 11 (see FIG. 3). This separation preventing portion 12 prevents the longitudinal weakening line 11 from being carelessly broken when the cap of the present invention is plugged, without providing the longitudinal weakening line 11 to the lower end portion of the fitting cylinder body 10. The separation preventing portion 12 having the same thickness as the fitting cylinder main body 10 is provided by leaving a part of the lower end portion. As described above, the longitudinal weakening line 11 can be prevented from being broken at the time of stoppering only by providing the separation preventing portion 12 having the same thickness as the fitting cylinder main body 10.

  The lateral weakening line 13 and the auxiliary lateral weakening line 14 are provided from the upper end portion of the longitudinal weakening line 11 along the peripheral edge of the upper end portion of the fitting cylinder body 10 (see FIG. 1). The lateral weakening line 13 is provided along the longitudinal direction of the hinge 20 from the upper end of the vertical weakening line 11. On the other hand, the auxiliary lateral weakening line 14 is provided extending in the opposite direction of the lateral weakening line 13 via the longitudinal weakening line 11. Although the lateral weakening line 13 and the auxiliary lateral weakening line 14 in the illustrated example are provided in a broken line shape, they can be formed in a thin shape or a groove shape. The lateral weakening line 13 and the auxiliary lateral weakening line 14 are set so that the user can remove the cap easily.

  That is, the distal end portion of the lateral weakening line 13 is located at a position 65 degrees from the center position of the fitting cylinder body 10 with respect to the virtual line S passing through the longitudinal center portion of the hinge 20 from the center position of the fitting cylinder body 10. To form. By setting in this way, when the upper lid 30 is gripped and lifted, this lifting force can be firmly transmitted to the fitting cylinder body 10. In other words, the force for removing the fitting cylinder main body 10 can be effectively transmitted to the fitting cylinder main body 10.

  On the other hand, the auxiliary lateral weakening line 14 extended from the upper end of the longitudinal weakening line 11 in the direction opposite to the lateral weakening line 13 can be naturally separated when the upper cover 30 is gripped and the fitting cylinder body 10 is lifted. Is set. That is, the distal end portion of the auxiliary lateral weakening line 14 is located at a position 65 degrees from the center position of the fitting cylinder body 10 with respect to the virtual line S passing through the longitudinal center portion of the hinge 20 from the center position of the fitting cylinder body 10. Is formed. When the auxiliary lateral weakening line 14 is cut, the total cut portion of the lateral weakening line 13 and the auxiliary lateral weakening line 14 is cut within a range of 130 degrees around the hinge 20. As a result, the fitting projection 15 of the fitting cylinder body 10 fitted to the undercut P2 of the container P can be largely opened, and the fitting cylinder body 10 can be removed more easily.

  In the procedure of removing the cap of the present invention, first, the upper lid 30 is grasped and the upper end portion of the longitudinal weakening line 11 is separated (see FIG. 5). At this time, as it is cut from the longitudinal weakening line 11 to the lateral weakening line 13, the separation preventing portion 12 is also cut off. If the upper lid 30 is pulled outward or slightly downward as it is, the entire lateral weakening line 13 is cut off. Further, the upper lid 30 is lifted as it is, and the auxiliary lateral weakening line 14 is naturally separated as the fitting cylinder body 10 is lifted (see FIG. 6). Then, the length sufficient to remove the fitting cylinder main body 10 is cut off, and the cap is easily removed from the neck portion P1 of the container P simply by lifting the upper lid 30 as it is. After that, the fitting cylinder main body 10 comes off from the neck P1 of the container P very easily. Therefore, the user only needs to lift the upper lid 30 after gripping the fitting cylinder body 10 and cutting off the upper end portion of the longitudinal weakening line 11.

  In addition, each structure of the illustration example in this invention is only one Example of this invention, and the longitudinal weakening line 11, the lateral weakening line 13, and the auxiliary lateral weakening line 14 are groove shape, broken line shape, cutting line shape, etc. The shape can be selected from easy-to-cut shapes, and can be freely changed within the currently known technical scope, such as the design change of the shape and dimensions of the fitting cylinder body 10, the hinge 20, and the upper lid 30, the change of material and the change of form. It is something that can be done.
