Problems solved by technology
When the connecting device (230) of the container cover (200) is folded and locked by the above-mentioned card edge (130), if the container main body (100) and the container cover (200) are combined, the liner will be pressurized to maintain airtightness property, cannot be unlocked arbitrarily
[0004] But, there is following defect in this container, one is that the structure formed by the protruding edge (110) and the protruding wing (120) of the front end of the container main body (100) is at right angles to each other, the junction (140) of this part is easy to enter foreign matter, and The foreign matter entering this part is not easy to clean, so there is a defect of uncleanliness; the second is that if the thickness of the protruding edge (110) of the container main body (100) is too thin, when the liner (210) of the container cover (200) is recessed and installed When the edge (220) is depressed, there is a defect that the airtight force decreases because the sealing surface is too small; especially, when the main body of the container is made of glass or ceramics, because the thickness of the edge (110) is too thick, in a long time When the locked state is maintained, as the interlocking force between the liner and the protruding edge increases, when the container cap is opened, there is a defect that the liner that is simply recessed into the concave edge of the container cap will be separated.
[0005] In addition, due to the structure of the container body, there must be a recessed edge for installing the liner on the container cover. After installing the liner on the above-mentioned recessed edge, if foreign matter enters the recessed edge, it will not only be unclean and hygienic, but will also remain. Washing water, creating unhygienic problems due to the inhabitation of various bacteria
[0006] In addition, if the main body of the container is made of glass or ceramics, the contact surface between the lip and the liner is large due to the thickness of the protruding lip. If this state is maintained for a long time, separate the container cap with the liner and the protruding lip attached together. , the liner will fall off at the same time

Embodiment Construction
[0026] Such as figure 1 and figure 2 As shown, in the composition of the present invention, the container cover (10) and the container main body (20) are exposed to the inside of the pressure surface (14) of the container cover (10) by means of the folded connecting device (11) in the container cover (10) The formed liner (30) is pressurized to be airtight, and the pressure surface (14) formed on the container cover (10) where the above-mentioned liner (30) is located is in a state of close contact with the flange formed around the upper end of the container body, The liner (30) is on the inner side of the above-mentioned pressurizing surface (14), and is exposed on the inner side of the container cover (10) through the through hole (17) of the container cover (10) by means of double injection molding, and a coating (31) is formed on the outer side. ).
[0027] At this time, the periphery of the upper end of the container main body (20) is protrudingly formed by a curved f...

A closed container lid with an exposed gasket structure is provided. A part for installing the gasket on the container lid is formed into a bending pressurized surface, the gasket is exposed towards the inner side of the pressurized surface, a through hole is formed on the container lid provided with the gasket, doubling injection molding of the gasket is realized through the through hole, and the gasket is protruded from the upper side of the container lid to form a coating layer which extends to the upper side of a connecting part, the connecting part with the coating layer can be kept flexible after repeated folding. The invention has the advantages that airtightness of the closed container lid can be kept, and well sanitary environment can be kept. The doubling injection molding of the gasket is realized through the through hole of the container lid to form a coating layer which extends to the outside of a connecting part, the connecting part with the coating layer can be kept flexible after repeated folding, and a plurality of appearance designs are provided, the gasket can be prevented from falling off.
Description
technical field [0001] The present invention relates to an airtight container, in particular to an airtight container in which a container main body and a container lid are folded by a connecting device to pressurize a liner to maintain airtightness. [0002] The present invention also particularly provides a container cap having an excellent locking function while maintaining airtightness with a glass or ceramic container body. Background technique [0003] See attached Figure 7 As shown, now, in order to maintain the airtightness of the airtight container, the structure of the container body (100) combined with the container cover (200) of the foldable connection device (230) has mostly protruding edges (110), protruding Wing (120) and card edge (130), the effect of protruding edge (110) is the recessed edge (220) of recessed installation container cover (200) liner (210) around the container upper end; Protruding wing (120) protrudes Below the edge (110), keep a certain...
