Abstract

end. The technical field to which the invention described in the claims belongs.

The present invention relates to a container lid formed of plastic, and more particularly to a coupling means of the packing used for the lid for sealing when the enclosure and the lid are combined.

I. The technical problem the invention is trying to solve.

The packing used for the sealing of the current container is inserted into the concave portion formed between the inner wall and the outer wall at the edge of the lid is inserted into the lid and the enclosure so as to be pressurized by a separate fastening means.

Therefore, a separate press means was necessarily required, and such a seal has a disadvantage in that the sealing force is remarkably weak by causing the upper edge of the enclosure to seal.

All. The gist of the solution of the invention.

It is provided with a packing that projects upward to the lower edge of the lid divided into an upper side and a lower side, so that when the lid is coupled to the enclosure, the packing is in close contact with the inner wall of the enclosure.

Description

A container lid which has a improved packing

The present invention relates to a container lid formed of plastic, and more particularly to a means by which the packing used for sealing the inside of the enclosure is coupled to the lid when the enclosure and the lid are combined.

Currently, the packing method used for sealing the container is to install the packing in the indentation caused by the inner wall and the outer wall formed on the edge of the lid or the enclosure. I'm doing it.

Therefore, for pressurization, a separate pressurization means was necessarily required, and the sealing force is remarkably weak by sealing only the upper surface of the enclosure or lid in contact with the packing even when the pressurization means is closed.

The present invention has been devised to solve the above-mentioned problems, the lid is divided into the upper and lower sides to engage with each other, and when the engagement is combined by pressing the packing to be fixed to require a separate pressing means It is possible to have a sealing force without, and the packing is to be in close contact with the inner wall of the enclosure to improve the sealing force.

Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention. First, the same reference numerals are given to the same parts as the conventional configurations.

As shown in FIG. 1, the constitution of the present invention is that the inward jaw 2 of the upper lid 1a and the outward jaw 3 of the lower lid 1b are engaged, and the upper side 1a or the lower lid 1b is engaged. On one side of the) forming a concave frame (5) for mounting the packing (4), the protruding frame (6) of the packing (4) fitted to the concave frame (5) is higher than the depth of the concave frame (5) It is formed so that the packing (4) is pressurized, it is possible to prevent the removal of the packing (4) in the pressurized state, the protruding frame (6) and the extended portion to be bent in the tip direction of the packing (4) By doing so, when the lid 1 is combined with the housing 10 is to be in close contact with the inner surface of the housing (10).

At this time, the inward jaw (2) of the upper lid (1a) is formed higher than the height formed in the indentation frame (5), the outward jaw (3) of the lower lid (1b) is also higher inward than the clip 7 formed in the corner Forming is to be pressurized only to one side while the packing is pressurized to facilitate engagement.

In addition, the rim 7 of the lower lid 1b forms an angular wall 8 having a space 9 as an inner edge portion of the inner rim 5 of the upper lid 1a, thereby forming the upper lid 1a. ) And the lower lid (1b) is to improve the airtight force when engaged.

In addition, when the packing 4 is engaged with the inward jaw 2 and the outward jaw 3 of the upper lid 1a and the lower lid 1b and is coupled, the pressure is extended from the outer jaw 3 of the lower lid 1b. Pressed by the blade (3a), the packing (4) is pressed in the state supported on the wide support surface (5b) of the partition wall (5a) constituting the concave frame (5) of the upper lid (1a) Therefore, no packing damage occurs.

In this case, when the pressure is applied, the pressure may be fixed at the same time as the adhesion by the adhesive means to prevent the packing 4 from falling out of the inlet frame 5.

At this time, the inner side of the upper lid and the lower lid formed with the inward jaw and the outward jaw can be used as an auxiliary coupling means for increasing the coupling force by engaging by a separate coupling protrusion 11 and the indentation protrusion 12. .

Therefore, when the upper lid (1a) and the lower lid (1b) is coupled while pressing the packing 4, the lid is inserted into the housing 10 by the recess groove rim 13 formed on the edge of the upper lid (1a) As the lower lid 1b is inserted into the enclosure 10, the packing 4 is bent upward from the lower lid 1b, so that the entire surface of the packing 4 is almost bent on the inner wall of the enclosure 10. In this state, the width of the indentation groove rim 13 is smaller than the width of the wall of the enclosure 10 and the width of the folding thickness of the packing 4. Since the entire surface of the c) is in close contact with the inner wall surface of the housing 10, the packing 4 is not inverted so that the lid does not open arbitrarily.

As described above, in the present invention, when the lid is closed, the packing is in close contact with the inner wall of the enclosure, thereby completely sealing.

Claims (5)
