AI Technical Summary

Technical Problem

The conventional beverage server configuration requires separate parts for sealing the gap between the mouth of the beverage container and the adapter, and a check valve, increasing the number of parts and assembly steps.

Method used

A gasket for a beverage server is designed with a seal portion and a check valve portion molded from an elastic material, which seals the space between the beverage container and the adapter and elastically deforms to open or close the gas inlet passage based on pressure differences, eliminating the need for separate parts and assembly steps.

Benefits of technology

The integrated gasket reduces the number of parts and assembly steps, preventing gas leakage and beverage intrusion while maintaining the pressurized state of the beverage container, thus reducing costs and improving assembly efficiency.

Abstract

To provide a packing for a beverage server that can reduce the number of components and assembly man-hours.SOLUTION: In a packing 42 for a beverage server that is mounted between an adapter that is mounted to a mouth part of a beverage container and the mouth part of the beverage container, an elastic material is formed as a raw material, by closely contacting an outer edge of the mouth part of the beverage container and over the entire circumference of the adapter, a seal part 43 that seals between the beverage container and the adapter except for a beverage lead-out passage of the adapter and a check valve part 45 integrally molded with the seal part 43 so as to be connected to a gas introduction passage of the adapter, when a pressure in the gas introduction passage is relatively higher than the pressure inside the beverage container, the gas introduction passage and the beverage container are elastically deformed so as to open to each other, and when the pressure in the gas introduction passage is relatively lower than the pressure inside the beverage container, the container deforms elastically so that a space between the gas introduction passage and the beverage container is closed are provided.SELECTED DRAWING: Figure 12
