Description

[Detailed description of the invention] [Industrial application field] This invention sends compressed air into the medium bottle through the air passage of the stopper, and pours out the contents of the medium bottle from the spout of the pouring passage. The present invention relates to the structure of a stopper used in such an air-compressed liquid container.

[Conventional technology]

Conventionally, as a stopper for this type of air-compressible liquid container, as described in Japanese Utility Model Application Laid-open No. 50-29364, the stoppers have (a) a stopper body having a ventilation hole in the upper plate part and a liquid passage; The valve body is provided with a valve body housed in a valve chamber communicating with a vent hole, and a pumping pipe is connected to the liquid passage of the stopper body to connect the two, while the valve body has vent holes at both upper and lower ends. There is known a structure in which partition walls are formed respectively, and compressed air from a compressed air source is sent into the medium bottle from a vent hole in the stopper body through upper and lower vent holes in the valve body.

(b) As described in Utility Model Application Publication No. 50-111758, the above
A plug body formed almost in the same manner as (a), a valve body (closer) internally movable up and down in a valve chamber communicating with the ventilation hole of the plug body, and a valve body (closer) that regulates the downward movement position of the valve body and A pumping pipe similar to that in (a) above is connected to the liquid passageway of the stopper body, and a number of holes are provided on the outer peripheral wall of the valve body (closer). Compressed air from the compressed air source is sent into the medium bottle through the vent hole in the stopper body, through the gap between the vertical strip on the outer circumferential wall of the valve body and the inner wall of the valve chamber, and through the vent hole in the bottom cover. It is also known that the configuration is as follows.

[Problem that the invention attempts to solve]

However, according to the above conventional example (a), (a) the vent hole in the stopper body and the vent hole formed in both the upper and lower ventilation partitions of the valve body communicate directly without detouring, so the container body If the bottle falls over, there is a problem that the solution inside the bottle may directly pass through these vent holes and enter the compressed air source, or may be scattered outside.

(b) In addition, a set of ventilation partitions must be formed at both the upper and lower ends of the valve body, and multiple ventilation holes must be formed in each ventilation partition, which not only requires a large number of parts but also requires multiple ventilation holes. There were drawbacks such as the need for complicated processing operations to form pores.

According to conventional example (b), (c) in order to form a gap between the outer circumferential wall of the valve body and the inner wall of the valve chamber, it is necessary to form a plurality of vertical stripes on the outer circumferential wall of the valve body, which is troublesome in processing. It was hot.

(d) In addition to the valve body, there were problems such as the need for a bottom cover to restrict the downward movement of the valve body, which required a large number of parts and required processing time.

This invention attempts to provide a solution that eliminates all of the above-mentioned problems.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention is an air compressed liquid liquid that sends compressed air into the medium bottle through the air passage of the stopper, and pours out the solution in the medium bottle from the dispensing passage. In the stopper for a container, the stopper body includes a stopper body integrally formed with an air introduction pipe forming part of an air passage and a liquid passage pipe forming a part of a pouring passage, and a lower opening of the stopper main body. The stopper is composed of a bottom lid that loosely fits into the stopper, and a gap is formed between the lower opening edge of the stopper body and the bottom cover, and this gap is used as an air passage. .

The bottom lid of the stopper is integrally formed with an outer cylinder having a crescent-shaped cross section and a bottom, and a ring-shaped liquid passage tube guide tube, and the elbow-shaped stopper body is attached to the liquid passage tube guide tube in the form of a ring. The hanging part of the liquid passage pipe can be fitted and fixed.

A vertical notch is formed on the outer wall of the outer cylinder near the liquid passage pipe guide cylinder of the stopper bottom lid, and a vertically long outward rib is formed on the upper part of the hanging part of the liquid passage pipe of the stopper body. The notch of the outer cylinder and the outward rib of the liquid passage pipe may be engaged with each other when the stopper main body and the stopper lower cover are connected.

Therefore, just by loosely fitting the stopper body and the bottom cover,
Not only is an air passage formed from the air introduction hole to the air guide part and the gap (air passage),
Since this air passage is formed as a detour,
It is possible to provide a stopper for a compressible liquid container that prevents the solution inside the medium bottle from entering a compressed air source or scattering when the container body falls over.

(2) The plug body has a plug body that is integrally formed with an air introduction pipe that forms part of the air passage and a liquid passage pipe that forms part of the pouring passage, and a plug body that loosely fits into the lower opening of the plug body. Since the valve body is composed of a valve bottom cover and a valve bottom cover, a set of ventilation partitions is formed at both the upper and lower ends of the valve body, and a plurality of ventilation holes are formed in each ventilation partition, as in the conventional example (a). As in conventional example (b), the work requires a large number of parts and processing time, such as forming multiple vertical stripes on the outer circumferential wall of the valve body and requiring a bottom cover to restrict the downward movement of the valve body. etc. are no longer necessary. Therefore, according to the present invention, the number of parts is small and assembly is easy.
