Problems solved by technology

However, in the sealing part of this structure, individual cut-off pieces smaller than other parts of the sealing part will be produced by unsealing. Depending on how the cut-off pieces are handled, the cut-off pieces will fall into the inlet after opening and be caught in the valve of the automatic on-off valve. Between the body and the valve seat, it hinders the sealing of the valve of the fittings, and there are problems such as contamination of liquid beverages.
In addition, the generated small cut pieces are scattered around, which is not very good in terms of resource recovery from the viewpoint of environmental protection.

Embodiment Construction

[0024] Embodiments of the sealing structure for the mouth of the drum-shaped container of the present invention will be described below with reference to the drawings.

[0025] exist image 3 In , the packaging structure 10 of this embodiment is shown in a state of packaging the mouth portion 1 by a cross section. This sealing structure seals the opening 2 of the mouth 1 opened by the drum-shaped container 6, and is composed of a cover 11 and a sealing part 15. The cover 11 is connected to the end surface 3 of the mouth 1 to cover the opening 2. ; The sealing portion 15 fixes the cover 11 at the mouth. The cover 11 has a flat part 12 connected to the end face of the mouth and a flange part 13 formed along the entire circumference of the flat part 12 and extending in a direction intersecting with the flat part 12. The resin material is integrally formed. Therefore, this cover is made of thin plastic and is lighter, but even if it is not fixed at the mouth of the drum-shaped ...

Abstract

The invention provides a sealing structure capable of preventing foreign matters from mixing into a spout of a barrel-shaped container filled with a liquid beverage for hygienic storage. It is characterised that the sealing structure of the spout includes a cap for covering an opening of the spout of the barrel-shaped container and a seal made of a heat-shrinkable tube for fixing the cap to the spout. The cap includes a flat part facing the end face of the spout and a flange extending from the periphery of the flat part in a direction of intersection with the flat part, and a component of the sealing structure can be used as a simple cap for covering the spout also after unsealing.

Description

technical field [0001] The present invention relates to a sealing structure for the mouth of a drum-shaped container, and particularly relates to a sealing structure for sealing the mouth of a drum-shaped container filled with liquid beverages such as beer. Background technique [0002] When liquid beverages such as beer are extracted from a drum-shaped container and filled into the container, usually, the mouth formed in the drum-shaped container is connected to a dispenser through a joint, and the liquid beverage is extracted through the dispenser. Therefore, the mouth portion suitable for installing the coupling piece used for connecting the above-mentioned dispenser is preliminarily provided on the drum-shaped container for filling liquid beverage. In such a drum-shaped container, after the drink is filled inside, the opening of the mouth is sealed to prevent foreign matter such as dust from entering during transportation or storage. [0003] As the structure of the exi...
