Abstract

(57) [Summary] [Problem] The lower part (3) of the bottle stopper body (1) because the purpose of the bottle stopper body (1) is to separate and recycle it as resource waste after use. When the bottle stopper main body (1) is inserted into the cylindrical bottle without attaching the aluminum foil (11) serving to prevent the lifting of the bottle, and the aluminum foil is not attached, the bottle opening (1)
2) The biggest issue is how to avoid coming up. SOLUTION: When a bottle stopper is inserted into a lower part (3) of a bottle stopper main body (1), it tightly adheres to an inner wall of a bottle mouth (12).
By inserting the convex lines (4) (5) (6) (7) of the book,
The problem can be solved.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a resin bottle stopper for fitting a bottle mouth in a cylindrical bottle that needs to be hermetically sealed.

[0002]

[Prior art]

 In a conventional cylindrical bottle used for containers of alcoholic beverages and liquid seasonings, the conventional bottle stopper is generally used for 1.8 liter bottles. Is sealed with a bottle stopper, and then sealed with a circular crown (13). The conventional bottle cap body (8) is integrally formed of resin, and has a thin metal plate on the head (9) and an aluminum foil (11) on the lower part (10). By attaching this aluminum foil, the bottle stopper is prevented from floating or flying out of the bottle mouth (12) during use. Conventional bottle stoppers Figure 2 is made of a combination of three types of raw materials, resin, metal and aluminum foil, and it is difficult for users to separate resources after use. There are some bottle stoppers made of resin alone and bottle stoppers integrally formed with the cylindrical crown (13), but aluminum foil on the lower part of the bottle stopper (11) is attached. Also, as shown in Fig. 2, the original bottle stopper is made by inserting one or two convex lines without sticking aluminum foil. However, the way of inserting the convex lines is unstable and many of them stick aluminum foil.

[0003]

[Problems to be solved by the invention]

 In the present invention, it is easy to integrate the bottle cap body (1) of the present invention in FIG. 1 and to make all of it with resin, but in the lower part (3) of the bottle stopper (1) of the present invention, The challenge is to prevent the bottle stopper from floating or flying out of the bottle mouth (12) without sticking the aluminum foil (11). If this problem is solved, it will be easier to separate the resource waste.

[0004]

[Means for Solving the Problems]

 In order to consider the means to solve the problem, the bottle stopper with a convex line similar to Fig. 1 of the bottle stopper used in a part of the conventional bottle stopper is made of aluminum foil (11). I asked if there were many bottle stoppers. According to the standard of 1.8 liters of the bottle opening (12) of the Japan Glass Bottle in 1997, 20.00 ± 0.9 mm was recognized, and there was actually an error in the inner diameter. . In order to solve the problem, it was considered important to make a bottle stopper focusing on this.

[0005]

[Embodiment of the invention]

 Considering the error of the inner diameter of the bottle mouth (12) + 0.9 mm, a lot of convex lines are inserted in the lower part (3) of the bottle stopper of the present invention, and the height of the convex line is made as high as possible at the time of molding. We decided to make the bottle stopper lower part (3) of the present invention so that when the bottle stopper was fitted into the mouth (12), the diameter of the bottle tightly adhered at several places in the bottle.

[0006]

【Example】

 Four independent lines, ie, convex lines (4), (5), (6) and (7) are inserted into the bottle stopper lower part (3) of the present invention one by one. The diameter excluding the convex line is 19.2 to 20.0 mm, the height of the convex line is 1.60 to 2.00 mm, and the diameter is 20.8 to 21.5 mm. Convex line (7) was slightly lowered in consideration of insertion into bottle opening (12), or the convex line of (7) was eliminated to make it rougher than the convex line of (6). You may make a bottle stopper.

[0007]

[Effect of the invention]

 Even if the aluminum foil (11) is not attached, a devised convex line that no one has ever thought can be inserted into the lower part (3) of the bottle stopper body (1) of the present invention, and the bottle stopper floats from the bottle mouth (12). The fact that the bottle does not rise or fly means that the bottle stopper is made of resin only, and after use, the separation of resource waste becomes easy and answers the demands of consumers. It is also thought to help reduce costs.
