Description

[Detailed explanation of the idea] This proposal concerns a barrel-shaped container made of synthetic resin.

Recently, small metal containers in the shape of barrels have become popular as beer storage containers, but these containers have the drawback that they require labor and labor to clean and sterilize when reused.

The present invention eliminates these drawbacks and also makes it possible to manufacture it at a low cost by making it made of synthetic resin.

Referring to the drawings below, reference numeral 1 indicates an outer container made of synthetic resin. The outer container has a barrel-shaped appearance, and in order to give this appearance, protrusions 2, 2 in the shape of a tightening ring are provided around the outer surface of the body. The outer container is formed by fitting the lower half 3 of the outer container and the upper half of the outer container. The lower half 3 of the outer container has a lower half body 5 standing up from the periphery of the bottom wall 4, and the upper end 6 of the lower half body is formed into a fitting part. The upper half 7 of the outer container is
It has an upper half body part 8, with an inward flange 9 protruding from the inner surface of the middle part of the upper half body part 8, and a short spiral cylinder 10 protruding from the inner peripheral edge of the flange. The upper end of the lower half trunk and the lower end of the upper half trunk can be removably fitted. The fitting portion is preferably made airtight, and an O-ring 11 is provided around it for airtightness. Opposite through holes 12, 12 are provided in the upper half body portion above the inward flange, and the upper half body portions above the through holes are used as handle portions 13, 13.

Into the outer container is inserted an inner container 18 made of synthetic resin, which has a body 15 erected from the periphery of the bottom wall 14 and a neck 17 for attaching a cap, etc., erected from the upper end of the body via a shoulder 16. The neck portion 17 is made to protrude upward from the hole of the inward flange and is housed. The inner container may be formed of so-called PET by biaxial stretching. Since the inner container is disposable,
Make it as thin as possible. However, since the mouth and neck require appropriate rigidity in order to attach a cap, etc., they are made to have an appropriate thickness. When blow molding is performed by biaxial stretching, it is easy to provide an appropriate thickness to the neck and neck portions and the shoulder portions adjacent to the neck and mouth portions.

A presser cap 19 is screwed into the short screw tube 10 described above. The presser cap has a through hole in the top wall 19a for inserting the mouth and neck of the inner container. Match. In this screwed state, a part of the top wall is provided so as to be in direct contact with the mouth and neck or the outward flange 17a attached to the mouth and neck, and the short screw tube and the mouth and neck are airtightly sealed directly or through a presser cap. An O-ring 21 is provided so that the

In the above configuration, the inner container is filled with a liquid such as beer, and the mouth portion is closed with a cap or stopper for transportation. To take out the liquid, remove the cap etc.
To refill the inner container after it is empty, remove the presser cap and the upper half of the outer container, take out the inner container, insert a new inner container, forcefully fit the upper half of the outer container, and then Attach the presser cap 18. Liquid filling into the inner container may be performed either before or after fitting the upper half of the outer container. Empty inner containers are disposable and should not be reused. However, it can be used for other purposes.

This project has the above structure, and since the inner container is a disposable container with double inner and outer containers, cleaning, sterilization, etc. will not be incomplete unlike this type of conventional containers, and the inner container is thin. Because it is a container, it maintains its strength through biaxial stretching, and can be made extremely thin, so even if it is a disposable container, there is little loss.
Since the outer container is thick, the inner container will not be damaged even if the inner container is thin, and the O-ring 1
1 and 21, it is easy to make the space between the outer container and the inner container airtight, and by doing so, it is possible to make the inner container, especially the peripheral wall and bottom wall, oxygen permeable. Even if it is made thinner, the outer container prevents oxygen from permeating, and there is no risk of the filling liquid changing in quality. Since it is made of synthetic resin, it can be manufactured at low cost.
