Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a cap that guarantees the quality of the contents of a bottle that cannot be reattached by human power once removed.

"Prior Art" A so-called sealing cap has this type of bottle content guarantee function. There are various types of sealing caps. For example, the outer surface of the sealing cap is covered with a thin resin virgin seal cap that can be easily broken and removed, and the cap can be removed unless the virgin seal cap is removed. Widely used are those which are not provided, or those in which a part of the lower portion of the peripheral wall of the mounting of the sealing cap is used as a virgin seal and the sealing cap cannot be removed unless the virgin seal is broken and removed.

"Problems to be solved by the invention" The sealed type does not hinder the cap mounting even if the virgin seal is removed, so it is convenient for large bottles that do not consume the contents at once after opening, but on the other hand The consumer may inadvertently or not be aware that the virgin seal has already been removed, which is problematic.

The present invention has an attachment structure that cannot be reattached by human power once removed, and obtains a cap that can be guaranteed almost completely without any error.

"Means for Solving the Problem" The cap of the present invention is a bottle 1 which is fitted into the mouth and neck 2 from the back surface of the top wall 4 of the cap body 3 which is mounted on the outer surface of the neck and which is below the mounting portion. An inner plug 6 that reaches the expanded diameter portion 5 is vertically provided. The inner plug 6 has a split groove 7 in the lower half portion in the circumferential direction, and the lower end is expanded outward to a diameter larger than the bottle diameter. Diameter 8
The elastically deformable skirt portion 9 is characterized in that the elasticity of the skirt portion 9 is such that it cannot be closed by human power.

[Operation] In the above, the skirt portion 9 lower end enlarged diameter portion 8 of the inner plug 6 has a diameter larger than the diameter of the bottle 1 and the skirt portion 9 is elastic so that it cannot be squeezed by human power, that is, fingertip force. After the contents are stored on the side, they are closed by a mechanical force of an appropriate jig or the like and fitted into the mouth / neck portion 2, and thereafter, they are forcibly pushed in manually and a cap is attached.

When detaching, the enlarged diameter portion 8 at the lower end of the skirt portion 9 is the mouth neck 2
Since it is deformed due to squeezing, it can be separated from the neck 2 though it is somewhat heavy. Once removed, the skirt 9 cannot be reattached because it is elastic so that it cannot be squeezed by human power as described above, and therefore the quality of the contents of the bottle 1 is unchanged because the cap is normally attached. This proves that the quality can be guaranteed almost completely.

[Embodiment] An embodiment will be described below with reference to the drawings. In the present invention, an attachment structure that cannot be reattached by human power once removed is provided so that a substantially perfect quality assurance function can be obtained without error. It is characterized by

For this reason, as shown in FIG. 1 to FIG. 3, from the vicinity of the periphery of the back surface of the top wall 4 of the cap body 3 which is screwed on the outer surface of the mouth and neck portion 2 of the bottle 1 through the mounting peripheral wall 10, An inner plug 6 that fits inside the mouth / neck portion 2 and reaches the diameter-enlarged portion 5 of the bottle just below the mounting portion is hung, and this inner plug 6 is provided with a lower half portion and split grooves 7 on all sides. Further, the lower end enlarged diameter portion 8 is an elastically deformable skirt portion 9 which is outwardly expanded into a diameter larger than the diameter of the mouth / neck portion 2; however, the elasticity of the skirt portion 9 can be squeezed by the wall of the mouth / neck portion 2. Therefore, the structure is such that it can be slid in and out, but it cannot be closed by human power, that is, by the force of a fingertip or the like.

That is, according to this embodiment, once the cap is removed, it cannot be manually attached, so that the bottle 1 does not become a product without the cap when it is removed, and thus a substantially perfect quality assurance function can be obtained.

The cap of the present invention is molded and manufactured from a synthetic resin material, but a material having high lubricity is preferable. Since the cap of the present invention cannot be reattached manually, it is suitable for a small-capacity bottle that consumes the contents all at once after opening, but of course it can be used for a large-capacity bottle that does not consume the contents at once. That is, in this case, a separate plug may be attached.

As the bottle 1 shown in the above-mentioned embodiment, the mouth / neck portion 2 has a long length, and the upper portion having a thread formed on the outer surface serves as a mounting portion, and the lower portion of the mouth / neck portion 2 below the mounting portion is expanded in diameter. Although the inner diameter-increased portion 5 is shown, the bottle inner diameter-increased portion 5 may be a shoulder portion or a body portion depending on the length of the mouth / neck portion 2.

[Advantage of Device] As described above, according to the present invention, from the back surface of the top wall 4 of the cap body 3 mounted on the mouth / neck part 2 of the bottle 1 to the inner part of the mouth / neck part 2 to reach the enlarged diameter part 5 in the bottle. A stopper 6 is hung vertically, and the inner stopper 6 has an elastically deformable skirt portion 9 whose lower half has an enlarged diameter portion 8 having a diameter larger than the bottle diameter, but this skirt portion 9 is once removed. Since the strength is such that it cannot be reattached manually, it is possible to provide a cap that can guarantee the quality of the contents of Bottle 1 almost completely.
