Description

  The present invention relates to a tamper-evident hinge cap that determines whether or not tampering has occurred, and more particularly, to a tamper-evident hinge cap that makes unauthorized tampering difficult.

  Patent Documents 1 to 3 disclose that a hinge cap that covers a container containing food or other liquids can be discriminated whether or not it has been tampered with for the purpose of extracting contents or refilling mischief. It is described in. Each of these hinge caps is provided with a seal member serving as a tamper mark on the outer periphery of the cap so that the presence or absence of tampering can be determined based on whether or not the seal member is broken.

  That is, in the hinge cap described in Patent Document 1, a hooking portion formed on the cap is inserted between a band piece formed on a part of the outer periphery of the plug main body and the plug main body, and the hooking portion is inserted into the band. When the cap is opened, the plug body connecting portion on at least one end side of the strip is lifted by the latching portion when the cap is opened. It is intended to be broken. According to this patent document 1, when the cap is opened, the plug body connecting portion on at least one end side of the strip is broken, and it can be easily known that the cap has been opened.

  The hinge cap of Patent Document 2 is provided with an opening protrusion on the outer side of the cap, and a guard surrounding the opening protrusion of the cap covering the container is provided on the side of the cap so as to be detachable. According to Patent Document 2, since the cap cannot be opened with the protrusion for opening the cap unless the guard is removed, the presence or absence of unauthorized opening can be determined depending on the state of attachment of the guard.

The hinge cap described in Patent Document 3 is provided with a locking projection on the upper surface of the pressing piece provided on the side opposite to the hinge of the cap, and on the engagement piece provided on the cap via the thin portion, Engagement protrusions to be engaged are provided. According to Patent Document 3, since the engaging piece is cut off from the thin portion in order to open the cap, it is possible to determine the presence or absence of unauthorized opening in the connected state of the engaging piece.

  Each of the hinge caps described in each patent document determines whether or not tampering has occurred by determining whether or not the seal member serving as a tampering mark has been broken. However, some of the sealing members described in each patent document can be opened illegally without breaking the sealing member, and the unauthorized opening act cannot be accurately determined.

  For example, in Patent Document 1, a strip is used as a seal member, and the strip is broken by the pulling force of the latch inserted between the strip and the plug body. If a thin piece or the like is inserted into the gap between the belt and the strip to release the engaged state, the strip can be opened without breaking. Moreover, since this type of hinge cap is formed of a synthetic resin material, it has a certain degree of flexibility, and insertion of a thin piece or the like can be performed relatively easily. In addition, when opened by such an unauthorized means, not only does the strip not break, but also there is almost no trace of unauthorized opening, so there is a disadvantage that confirmation of unauthorized opening becomes more difficult.

  Further, the seal member in Patent Document 2 uses a guard that surrounds the opening protrusion, and the cap cannot be opened with the opening protrusion unless the guard is removed. However, it is possible to open the cap without having the cap opening protrusion. For example, it can be easily opened by inserting a thin piece into the gap of the cap. Therefore, even with the guard of Patent Document 2, similarly to Patent Document 1, it is difficult to accurately determine unauthorized opening, and even if opened by unauthorized means, there is almost no trace of unauthorized opening, There is also an inconvenience that it is more difficult to check for unauthorized opening.

  Further, according to Patent Document 3, an engagement piece is used as a seal member, and it is determined that there is no unauthorized opening unless the engagement piece is separated from the thin portion. However, since the material of the engagement piece is a synthetic resin material, it has a certain degree of flexibility. And since the thin part is provided in the position most distant from the engagement protrusion, it is not a very difficult operation | work to cancel | release an engagement state, without cut | disconnecting a thin part. Also in Patent Document 3, as in Patent Document 1 and Patent Document 2, even if the document is opened by unauthorized means, there is almost no trace of unauthorized opening, making it more difficult to confirm unauthorized opening.

  In this way, in the case where the seal member serving as a mark for determining whether or not the tampering is opened is provided and whether or not the tampering is opened can be determined based on whether or not the sealing member is broken, the tampering is accurately determined. It was difficult, and the tampering operation itself was not so difficult.

  Further, as in Patent Document 2 and Patent Document 3, in the case where the easily ruptured seal member for judging unauthorized opening protrudes from the side surface of the cap, an impact applied to the seal member is produced during the manufacturing of the hinge cap. There is also a risk that a large and easily broken sealing member may be damaged during the manufacturing process.

  Accordingly, the present invention has been created to solve the above-described problems, and it is extremely difficult to perform an unauthorized opening operation, and in addition, an unauthorized opening prevention hinge cap that can be reliably identified when there is an unauthorized opening. It is for the purpose of provision.

  The first means of the present invention has a fitting cylinder body 10 fitted to the outer side surface of the container neck, and an upper lid 30 slidably connected to the fitting cylinder body 10 via a hinge 20. A tamper opening 31 for opening and closing the top lid 30 is provided on the side surface of the top lid 30 that faces the hinge 20, and the tamper opening band 40 that engages with the manipulation collar 31 is provided in the fitting cylinder body 10. In the prevention hinge cap, the tamper-evident band 40 has a pair of engaging pieces 41 that engage with the upper surfaces of the left and right ends of the operating collar 31, and the tamper-resistant band 40 is connected to the fitting cylinder body 10. A weakening line 11 is provided on the fitting cylinder main body 10 to be separated from the fitting cylinder body 10.

  In the second means, the tamper-evident prevention band 40 includes a superposition piece 42 that is superposed on the lower surface of the operation lever 31 and a pair of engagement pieces 41 that are engaged with the upper surfaces of the left and right ends of the operation hook 31. The gripping piece 43 is extended from the one engagement piece 41 side in the circumferential direction of the fitting cylinder main body 10, and the picking piece 43 and the overlapping piece 42 are connected via the weakening line 11. And formed integrally.

  The weakening line 11 in the third means is attached to the engaging piece 41 from the first weakening line 11A and the first weakening line 11A that is cut off substantially horizontally from the knob piece 43 to the one engaging piece 41. The second weakening line 11B is cut off substantially vertically, and the third weakening line 11C is cut off substantially horizontally from the second weakening line 11B to the other engagement piece 41.

  In the fourth means, the overlapping piece 42 of the tamper-evident prevention band 40 is inclined from the outer peripheral edge portion of the operating collar 31 superposed on the overlapping piece 42 to the outer surface of the fitting cylinder body 10 below. The surface 42A is provided, and the locking convex portion 31A provided on the lower surface of the operation collar portion 31 is provided to be locked to the locking concave portion 42B provided in the upper surface of the overlapping piece 42. It is a means for resolving.

  According to claim 1 of the present invention, the upper lid 30 cannot be opened unless the tamper-evident prevention band 40 is cut along the weakening line 11. If the engagement state of one engagement piece 41 is illegally released, the engagement state of the remaining engagement piece 41 becomes more severe. As a result, even if an unauthorized opening operation is performed, it becomes extremely difficult.

  In addition, according to the tamper-evident band 40 in claim 2, since the knob 43 and the superposed piece 42 are formed integrally with the fitting cylinder body 10 via the weakening line 11, the weakening line 11 is separated. The upper lid 30 cannot be opened. In addition, when the weakening line 11 is illegally opened without being cut off, the engagement piece 41 is structured to be damaged, so that it is possible to accurately determine the presence or absence of the illegal opening.

  Furthermore, the weakening line 11 according to claim 3 facilitates the operation of separating the knob 43 and the superposed piece 42 from the fitting cylinder body 10. As a result, in the normal opening operation, the presence of the unauthorized opening prevention band 40 is not likely to interfere with the opening operation.

  Then, the tampering band 40 and the tampering prevention band 40 are superposed on each other by the tampering prevention band 40 according to the fourth aspect, and the operation treading part 31 is formed by the inclined surface 42A of the tampering prevention band 40. Therefore, it is not a structure that can be tampered with easily by simply inserting a thin piece as in the prior art, and tampering is extremely difficult. Moreover, since the tamper-evident prevention band 40 is located below the operation collar part 31 and does not protrude from the end of the operation collar part 31, there is no possibility that the tamper-evident prevention band 40 is damaged at the time of manufacturing the cap. In addition, the width of the operating collar 31 can be made sufficiently wide.

  As described above, according to the present invention, it is extremely difficult to perform an unauthorized opening operation. In addition, there is an excellent effect that an unauthorized opening operation can be reliably determined.

  In the best mode of the present invention, the tamper-evident band 40 has a pair of engaging pieces 41 that engage with the upper surfaces of the left and right ends of the operating rod 31, and is provided with a weakening line 11 that is separated from the fitting cylinder body 10. . On the tamper-evident band 40, a superposed piece 42 that is superposed on the lower surface of the operating collar 31; a pair of engaging pieces 41 that engage with the upper surfaces of the left and right ends of the operating collar 31; And a knob 43 extending in the circumferential direction of the fitting cylinder body 10 is provided. By providing the superposed piece 42 of the tamper-evident prevention band 40 with an inclined surface 42A that extends from the outer peripheral edge of the operating collar 31 of the upper lid 30 to the outer surface of the fitting cylinder body 10, the original purpose is achieved. .

  The cap of the present invention is a hinge cap that plugs into the neck of the container. This cap has a fitting cylinder main body 10, a hinge 20, and an upper lid 30, and the upper lid 30 is pivotably connected to the fitting cylinder main body 10 via the hinge 20 (see FIG. 2). An operating lever 31 for opening and closing the upper lid 30 is provided on the side surface of the upper lid 30 that faces the hinge 20.

  The operating collar 31 is a part that serves as a clue to the opening / closing operation of the upper lid 30 and is polymerized on a superposed piece 42 of an unauthorized opening prevention band 40 described later before opening (see FIGS. 5 and 7). The operating collar 31 is provided with a locking convex portion 31A and an engaging portion 31B. The locking convex portion 31A is a protrusion provided on the lower surface of the operating rod portion 31, and locks into a locking concave portion 42B that is recessed on the upper surface of the overlapping piece 42 described later (see FIG. 5). On the other hand, the engaging portion 31B is a concave portion provided at both the left and right end portions of the operating rod portion 31, and an engaging piece 41 of a tamper-evident band 40 described later is engaged with the engaging portion 31B. (See FIGS. 3 and 6).

  The tamper-evident prevention band 40 is provided on the outer surface of the fitting cylinder main body 10 and engages with the above-described operating collar 31 to prevent tampering (see FIG. 1). The unauthorized opening prevention band 40 includes a pair of engaging pieces 41 that engage with the upper surfaces of the left and right ends of the operating rod 31, and a superposed piece 42 that overlaps with the operating rod 31. Then, when the upper lid 30 is applied and the operation lever 31 and the overlapping piece 42 are overlapped, the locking projection 31A of the operation hook 31 is locked to the locking recess 42B of the overlapping piece 42 (FIG. 5). At this time, the left and right engaging pieces 41 are engaged with the upper surface of the engaging portion 31B of the operating rod portion 31 (see FIGS. 7 and 8). The illustrated engagement piece 41 is formed with a taper 41A at a contact portion with the operation rod 31 in order to facilitate engagement with the engagement portion 31B (see FIG. 6). In addition, the base end portion of the engagement piece 41 is formed thick in order to make it difficult to tamper with it after engagement. And the engagement piece 41 of an engagement state is provided so that it may be in the state enclosed by the operation collar part 31 and the unauthorized opening prevention belt | band | zone 40 (refer FIG. 7). By providing in this way, unauthorized opening of the engagement piece 41 can be made more difficult.

  Further, an inclined surface 42A is provided on the lower surface of the overlapping piece 42 in order to make it difficult to tamper with it after the engagement (see FIGS. 5 and 6). The inclined surface 42A extends from the outer peripheral edge portion of the operation rod portion 31 superimposed on the overlapping piece 42 to the outer surface of the fitting cylinder main body 10 below, and eliminates the clue at the time of opening the operation flange portion 31. It is formed for the purpose. Further, by providing the inclined surface 42A, there is an advantage that the superposed piece 42 itself becomes thick and is hardly deformed. In addition, since the tamper-evident prevention band 40 does not protrude from the end of the operation collar 31, there is no risk that the tamper-evident prevention band 40 will be damaged during the manufacture of the cap, and the width H of the operation collar 31 can be made sufficiently wide. Yes (see FIG. 8). FIG. 9 is a plan view of the case where the tamper-evident prevention band 40 is protruded from the operation lever 31 as in the prior art. If the tamper-evident band 40 protrudes from the operating collar 31 as described above, the tamper-resistant band 40 may be damaged during cap manufacturing or transportation. Moreover, since the width of the operation collar part 31 becomes narrower than the width H of the tamper-evident prevention band 40, the opening operation of the upper lid 30 becomes inconvenient.

  The unauthorized opening prevention band 40 is further provided with a knob 43 that extends from the side of one engagement piece 41 in the circumferential direction of the fitting cylinder body 10 (see FIG. 1). And these knob | pick piece 43 and the superposition | polymerization piece 42 are integrally formed with the fitting cylinder main body 10 via the weakening line 11 (refer FIG. 4). The weakening line 11 is provided in the fitting cylinder body 10 and separates the tamper-evident prevention band 40 from the fitting cylinder body 10. That is, the weakening line 11 is composed of the following three types of weakening lines 11. 11 A of 1st weakening lines cut | disconnect the pick piece 43 from the pick piece 43 to the one engagement piece 41 substantially horizontally. The second weakening line 11B is cut off substantially vertically along the engaging piece 41 near the end from the end of the first weakening line 11A. Then, the third longitudinal weakening line 11C is separated substantially horizontally from the second weakening line 11B to the other engagement piece 41. The upper lid 30 cannot be opened unless the knob 43 and the polymer piece 42 are cut along the weakening line 11A. Further, since the three weakening lines 11A are formed, the tamper-evident band 40 integrally formed via the weakening line 11A is firmly fixed to the side surface of the fitting cylinder body 10. As a result, there is no fear that the tamper-evident band 40 will be damaged along the weakening line 11A during the manufacture of the cap of the present invention, and the tamper-resistant band 40 along the weakening line 11A for tampering. Even if you try to transform it, it will be difficult.

  In the regular opening of the present invention, first, the knob 43 is cut substantially horizontally along the first weakening line 11A shown in FIG. 5, and then the superposed piece 42 is cut vertically along the second weakening line 11B. . Finally, the polymer piece 42 is horizontally cut along the third longitudinal weakening line 11C, and the polymer piece 42 is separated from the operation hook portion 31, and then the upper lid 30 is opened by placing a finger on the operation hook portion 31. is there.

  An inner ring 12 is formed on the fitting cylinder body 10 in the illustrated example, and the inner ring 12 is inserted into the mouth of the container (see FIG. 2). Further, a score 13 is formed inside the inner ring 12, and a tab 14 for breaking the score 13 is provided. By pulling the tab 14, the score 13 is broken. Further, on the upper surface side of the inner ring 12, a dispensing cylinder 15 for dispensing the content liquid is formed so as to surround the score 13. The illustrated upper lid 30 includes a top plate 32 and side walls 33 depending from the periphery of the top plate 32. A ring-shaped protrusion 34 for sealing is formed downward from the inner surface of the top plate 32. When the upper lid 30 is closed, the ring-shaped protrusion 34 comes into close contact with the inner surface of the dispensing cylinder 15.

  In addition, each structure of the example of illustration in this invention is only one Example of this invention, and the design change of the shape, a dimension, etc. of the fitting cylinder main body 10, the hinge 20, and the upper cover 30 is free. Further, the shapes and structures of the operation lever 31 and the tamper-evident prevention band 40 are not limited to the illustrated examples, and can be freely changed within the currently known technical scope based on the gist of the present invention.
