Document Type and Number:
Japanese Patent JP2023027493
Kind Code:
A
Abstract:
To maintain a quality of contents with the same configuration as much as possible before and after opening while giving a user a feeling of opening a package.SOLUTION: A container comprises a container body 1 and a lid 2. The lid includes stoppers 23 and 25 that are fitted to a mouth 12 of the container body so as to close an opening. The stopper includes a tubular metal layer 41 arranged concentrically with respect to the mouth. The mouth includes a mouth-facing layer 12a having a surface diametrically opposed to the stopper. The mouth-facing layer, which is made of resin having a lower melting point than a surface layer 42 including a surface of the stopper, has a welding mark 14 separably welded to the surface of the stopper when unopened, and indicating a welding state when unopened after opening. Welding is broken when opening, a feeling of opening is given to a user, and when the lid is closed after opening, the welding mark 14 and the surface layer 42 of the stopper face each other, so that a quality of contents can be maintained in substantially the same state before and after opening.SELECTED DRAWING: Figure 1
