[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pill faproof type cap in which a pill faproof hem that serves as a mark that the opening has been performed by being cut off from the cap body is continuously provided at the lower end of the peripheral wall of the cap body. Is.

[0002]

[Prior Art]

 The pilfap proof hem of the pilfap proof type cap is connected to the lower end of the peripheral wall of the cap body via a thin vertical weakening zone, which is generally called a sewing line or weakening line. To prevent the weakened band from being cut when attaching the cap to the bottle neck or when transporting a bottle tightly capped with a cap, the band is provided with a plurality of thick walls arranged intermittently in the circumferential direction. It is supposed to have a large bridge part. In many cases, the pill-proof cap has a structure in which the pill-proof hem is separated from the cap body along the weakened zone and left on the bottle neck when the screw is unscrewed from the bottle neck and first opened. However, the pill-proof hem that remains on the bottle neck needs to be removed from the bottle neck when collecting empty bottles and reusing glass for resource conservation purposes. It generally has an unsightly appearance when the cap is used to re-seal the bottle with the cap body without drinking or once.

Therefore, at the time of first opening, it is cut along the weakened band, but it is removed from the bottle neck while continuing to be connected to the cap body, and after removal, it is torn off from the cap body and removed. Pilfap-proof caps with parts are also becoming available. FIG. 10 shows a conventional example of such a cap mounted on a bottle neck portion B, in which a pill faproof hem portion 2 is provided at the lower end of the peripheral wall of the cap body 1, and a plurality of wall thicknesses are provided intermittently in the circumferential direction. The pilfap proof type cap, which has a large number of bridge portions 3 and 3A and is continuously connected via a thin weakened zone 4 along the circumferential direction, is further configured as follows. That is, one of the above-mentioned bridge portions is formed into a wide bridge portion 3A having a larger width in the circumferential direction than the other bridge portions 3, and one end of the wide bridge portion 3A is connected to the pilfap skirt. A vertical slit 5 reaching the lower end of the part 2 is provided in the pilfap proof hem 2. When this cap is unscrewed from the state of being attached to the bottle neck portion B shown in FIG. 10, the bridge portion 3 having a small width in the circumferential direction is torn along the weakened zone portion 4 and along the vertical slit 5 with the pilfer. Although the proof hem 2 is cut open, the wide bridge portion 3A is not torn due to its great resistance to tearing, and the pilfer proof hem 2 remains connected to the cap body 1 at the wide bridge portion 3A. Removed from bottle neck B. The pill faproof hem 2 can then be pulled by hand to tear the wide bridge portion 3A and remove it from the cap body 1.

[0004]

[Problems to be solved by the device]

 When the cap body 1 of the cap is used for the purpose of resealing the bottle neck B after the initial opening, the pilfap proof hem 2 is removed as described above, but one of the wide bridge portions 3A is removed at the time of removal. The portion often remains at the lower end of the cap body 1 as a protrusion 20 as shown in FIG. Therefore, according to the conventional cap, when the cap body 1 is resealed at the neck of the bottle, an accident occurs in which the protrusion 20 causes a finger injury. The present invention seeks to provide a safe Pilfa-Proof type cap that solves this problem.

[0005]

[Means for Solving the Problems]

 Therefore, as shown in FIGS. 1-9, the present invention provides a pill faproof type cap having a wide bridging portion 3A and a vertical slit 5 similar to that of FIG. A concave (FIG. 3) or convex (FIG. 9) reinforcing rib 6 is arranged at the upper end portion below the wide bridge portion 3A and is formed along the wide bridge portion 3A, and the wide bridge portion 3A is formed. At the end opposite to the vertical slit 5, the weakened band portion 4 is provided with an acute-angled corner portion 4a in which the lower end edge of the weakened band portion 4 is inclined upward toward the wide bridge portion 3A. In addition to the above structure, the present invention is arranged such that another concave or convex reinforcing rib 7 is arranged at the lower end of the peripheral wall of the cap body 1 and is arranged on the upper portion of the wide bridge portion 3A so as to extend along the wide bridge portion 3A. It is also proposed to do so (Claim 2).

[0006]

[Action]

 The operation when the cap according to the present invention is opened from the state of being attached to the bottle neck portion B as illustrated in FIG. 6 for the first time is similar to that described above with reference to the conventional example of FIG. As illustrated in FIG. 2, the pill-proof skirt 2 is removed from the bottle neck while being incised, but still connected to the cap body 1 at the wide bridge portion 3A. When the cap body 1 is grasped with one hand from the state shown in FIG. 7 and the pilfap proof hem 2 is pinched by the fingers of the other hand and pulled in any direction, the sharp corners clearly shown in FIG. Since 4a is left in the shape of a notch at the end of the wide bridge portion 3A, the wide bridge portion 3A does not necessarily start to split from the sharp corner 4a, and also the split ribs 3A lower the reinforcing rib 6 to split the slit. Is prevented from extending to the pilfap proof hem 2, the posterior tear progresses linearly in the wide bridge portion 3A, and along the weakened zone 4 as a whole as illustrated in FIG. The separated state of the pilfap proof hem 2 is obtained. According to the illustrated structure in which another reinforcing rib 7 is provided on the upper portion of the wide bridge portion 3A, even if a rough cutting operation is performed, the crack is prevented from proceeding to the cap body 1 side, and a concave shape is formed at the lower end of the cap body 1. The formation of the hollow portion never occurs, and the safety when the cap body 1 is reused is further enhanced.

【Example】

 FIG. 1-8 shows the first embodiment, and a cap made of a thin metal plate material such as aluminum is manufactured in a form having no threads on the peripheral wall of the main body 1 as shown in FIG. 1-5. After fitting on the neck B, as shown in FIG. 6, a thread 9 along the thread Ba of the bottle neck B is formed on the peripheral wall of the main body, and the skirt portion Bb of the bottle neck B has a lower end of the pilfer proof hem 2. It is supposed to be used to tighten the portion 2a. For sealing, a liner or packing P that is pressed against the bottle mouth is provided on the inner surface of the top wall of the cap body 1.

As shown in FIG. 4, the thin weakened zone 4 is formed on the peripheral wall of the cap body 1 so as to slightly inflate toward the inner surface of the cap, and the bridge portions 3 and 3 A are widened in FIG. As shown for the width bridge portion 3A, it has the same wall thickness as the peripheral wall of the cap body 1 and the pilfap proof hem 2. As shown in FIGS. 1 and 2, the wide bridge portion 3A is supposed to have a circumferential width several times that of the other bridge portions 3. While the screw thread 9 shown in FIG. 6 is a right-handed thread, the vertical slit 5 is arranged at the left end position of the wide bridge portion 3A as shown in FIGS. It is formed in the pilfap proof hem 2 as a cut from the upper edge position to the lower end of the pillfap proof hem 2.

As shown in FIGS. 1 and 2, the reinforcing rib 6 has the same vertical width as that of the weakened band portion 4, and as shown in FIG. 3, it has a concave shape that swells toward the inner surface of the cap. , Formed. While the cut at the weakened band portion 4 occurs along the upper edge of the weakened band portion 4, the reinforcing rib 6 shown in the figure has a wide bridge portion 3A having a smaller vertical width than the other bridge portions 3. It is provided at the upper end of the pill faproof skirt 2 in such a manner that the weakened strip portion 4 is inserted into the weakened strip portion 4 when viewed in the vertical direction.

As shown in FIG. 1, the acute-angled corner portion 4a is disposed at the right end position of the wide bridge portion 3A, and FIG. 4 and FIG. As can be seen from the comparison of FIG. 5, the lower end edge is inclined as described above, and the terminal end of the lower end edge is intersected with the upper end edge of the weakened strip portion 4 at a position slightly left of the right end of the reinforcing rib 6. It is supposed to be. Further, as shown in FIG. 1C, the other reinforcing rib 7 is formed in a concave shape having a vertical width similar to that of the weakened band portion 4 like the reinforcing rib 6. The other reinforcing ribs 7 are arranged on the peripheral wall of the cap body 1 such that the center positions of both the reinforcing ribs 6 and 7 are the positions corresponding to the upper edge of the weakened band portion 4 when viewed in the vertical direction. The horizontal axis of the wide bridge portion 3A at the position corresponding to the upper edge of the weakened zone 4 is set to the planned cutting line L of the wide bridge portion 3A shown in FIGS. As shown in FIGS. 1 and 2, the other reinforcing rib 7 protrudes from the right end to the acute-angled corner 4a side and the left end to a relatively large extent beyond the vertical slit 5 position. It is designed to prevent the cutting at the wide bridge portion 3A from advancing toward the cap body 1 side.

FIG. 9 shows a second embodiment in which the reinforcing ribs 6 and the other reinforcing ribs 7 are each formed in a convex shape that bulges toward the outer surface side of the cap. In other respects, the first embodiment is used. It is no different from the example. Note that one of the reinforcing ribs 6 and 7 may have a concave shape and the other rib may have a convex shape. The upper reinforcing rib 7 may be removed from the state shown in FIG. 7 by a rough cutting operation of the wide bridge portion 3A. However, even if a concave cutout portion is formed at the lower end of the cap main body 1, it is possible to omit it because it is much less dangerous than the protruding body 20 of FIG.

[0012]

[Effect of the device]

 According to this invention, as described above in the section of the operation, the separation of the pilfap proof hem 2 due to the tearing of the wide bridging portion 3A after the cap is removed causes the weakened zone 4 to have an acute angled corner 4a with an upward inclination. Since the guide ribs start from the end of the wide bridge portion 3A above the reinforcing ribs 6 and are achieved by the reinforcing ribs 6 without advancing to the pilfap proof hem portion 2 side, the conventional one shown in FIG. There is no room for the projecting body 20 to be left at the lower end of the cap body 1, and the safety of the pill-proof type cap of the type in which the pill-proof skirt 2 is removed together with the cap body 1 is greatly enhanced. According to the structure in which the other reinforcing rib 7 is provided on the upper portion of the wide bridge portion 3A, the wide bridge portion is not removed even if the pilfap proof hem 2 is detached from the cap removed state as illustrated in FIG. The tear of 3A never progresses to the cap body 1 side, and the lower end of the cap body 1 is perfectly smooth, which further enhances safety.
