Description of the Related Art A synthetic resin inner lid attached to a bottle mouth has been discarded while remaining in the bottle mouth even after the bottle has been used. Disposal of bottles remaining in the bottle mouth poses problems in recycling and incineration, and even in disposal, it is incompatible with today's legislation, which tends to require that materials be sorted and disposed of separately. There are various conventional examples for removing the inner lid stopper remaining at the bottle mouth, but basically a tab type is dominant. In the tab type, as shown in FIG. 8, the inner lid stopper A is attached to the bottle opening C in order to cut and remove the fastening portion 2 to the bottle opening C connected to the mounting portion 1. 2 is provided with a weakened portion such as a thin slit, and a tab 3 for cutting (cutting) the weakened portion is provided on the outer peripheral surface portion of the tightening ring portion 2. In this conventional example, although the tab 3 has the effect of ensuring that the tab 3 is cut (cut), the tab 3 is exposed in a crowned state, so that the contents remain in a state where they remain and can be discarded. Even if the bottle is not reached, there is a problem that the inner ring cap is accidentally detached due to the fact that the bottle ring 2 is removed due to the curiosity at the time of sales at the time of handling such as moving work and the like and the inner ring stopper 2 is removed. In order to solve this problem, the present applicant has proposed Japanese Patent Application Laid-Open No. 5-217906. In this prior proposal, as shown in FIG. 9, the outer peripheral surface of the outer cylinder 21 of the mounting portion 1 on which the engaging convex portion 21a for mounting the canopy B is formed,
A step 8 is formed between the outer peripheral surface of the collar portion 2 and the annular thin portion 4 which is formed on the inner peripheral surface of the collar portion 2. A thin slit for vertical splitting 5 extending to the fastening bead 12 at the lower end is cut in the fastening ring portion 2 crossing the slit 4, and a slit hole 15 communicating with the thin slit 5 for vertical split is formed in the step portion 8. Since the slit hole 15 is closed at the lower end surface of the canopy B and is not exposed to the outside in the crowned state, it is possible to prevent the fastening ring portion 2 from being erroneously cut or cut off at the store by mischief. .

This embodiment is an example in which the tab 3 is not shaped like a letter as described above, but is inclined toward the outer cylinder 21. . The tab 3 is a thin inclined piece that is inclined so as to approach the step top surface 22, and is recognized as the tab 3 in comparison with the above-described tab 3 because of its planar shape approaching the step top surface 22. In consideration of the difficulty, a rib 23 is protruded from one side edge portion on the side away from the traveling direction (arrow D), that is, the edge portion on the opposite side to have rigidity.

面視横長形状をもって凹設されている。The reason for accommodating the tip of the inclined piece 3 ′ in the accommodating recess 6 is to make it difficult to pick the tab (inclined piece) 3 as much as possible. Instead, one side edge of the tab 3, that is, the rib 23 is attached. It is recessed with a laterally long shape in a front view that secures the finger insertion portion 16 on the side of the protruding edge portion.

It is continuous with an inclined shape. The hole directly below the inclined piece 3 'is a hole which is formed in the same manner as in the above embodiment.

リット４とが共に切断される。In the embodiment shown in FIGS. 7 and 8, since the tab 3 is inclined with a thin flat surface in a direction approaching the step top surface 22, it is difficult to recognize the tab 3 as it is. Then, a fingernail or a finger is inserted into the finger insertion portion 16, the tab 3 is raised so that the distal end side thereof comes out of the accommodation recess 6, and the tab 3 is pulled in the circumferential direction (the traveling direction (arrow D)) in the same manner as in the above-described embodiment. As a result, both the vertical slits 5 and the annular thin slits 4 are cut.

Includes In this case, the slit width of the notch is made as narrow as possible so that dust or the like does not enter.

中蓋栓の提供を可能にする。As described above, the present invention is constructed as described above. Therefore, at the time of moving work such as display at a store or sales at a store, a tab which is protected by the cap and not exposed is picked up and discarded when the bottle is discarded. The ring can be cut. Therefore, although the tab ring type can be easily cut using fingers without using a tool, the ring ring is cut off incorrectly at the time of moving work such as displaying at a store or selling at the store. It has a removal function that does not cause the ring part to be cut by pranks, and does not leave a space with an open top like a slit hole. It is possible to provide a synthetic resin inner lid stopper that is not produced. In addition, when the tab is formed of a thin inclined piece that is inclined in the outer cylinder direction of the mounting portion, the locking portion is not erroneously cut, and the locking portion is not cut by mischief. Since it is inclined with a thin flat surface in the direction approaching the top surface, it is difficult to recognize it as a tab, and therefore, it can also contribute to the prevention of the problem that the ring portion is cut off by curiosity of a child etc. during normal use. . No. In addition, an accommodating recess for accommodating the distal end of the tab is formed in the outer cylinder, and the accommodating recess is formed in a front view shape in which a finger insertion portion is secured to the side of the side edge of the tab. Even if is steeply inclined (inclined in a direction approaching the top of the step), the tab can be picked by inserting and raising the nail or finger of the finger holder. Therefore, since the flat and inclined tabs are closer to the top of the step, it is difficult to recognize them as tabs, so that they can be excluded from objects of curiosity such as infants during normal use, and adults pick the tabs spontaneously. It is also possible to provide a certainty of cutting the ring fastening portion, and to provide a synthetic resin inner lid plug having an optimum removing function in consideration of prevention of cutting of the ring fastening portion during normal use.
