Title:
BEVERAGE CONTAINER AND PLUG PACKING
Document Type and Number:
Japanese Patent JP2023103671
Kind Code:
A
Abstract:
To provide a technique capable of improving a fitting force between a plug packing and a plug of a beverage container by a method different from a conventional method.SOLUTION: A beverage container 1 includes a container body 10, and a cover unit 20 fixed to a top of the container body 10. The cover unit 20 has: a cover portion 42 that covers an upper opening of the container body 10; and an annular plug packing 24 interposed between the cover portion 42 and an upper end portion of the container body 10. The cover portion 42 has an upwardly recessed annular groove 420 on its lower surface. The plug packing 24 fits into the groove 420. The plug packing 24 has a plurality of projections 50 projecting outward from an annular outer peripheral surface. Thereby, a fitting force of the plug packing 24 is partially improved at a position where the projections 50 are arranged in a circumferential direction. Since the fitting force is improved only in a part of the circumferential direction, it is easier to attach and detach the plug packing 24 compared to a case where the fitting force is improved in an entire circumferential direction.SELECTED DRAWING: Figure 8
