CN101332924A - Sealed container capable of preventing locking sheet from being disengaged automatically - Google Patents

Abstract

A sealed container for preventing a locking sheet from being disengaged by itself is characterized in that: a convex stop table is arranged on the bottom surface of the groove wall of the annular groove for accommodating the sealing gasket of the container cover, and the stop table is tightly attached to the upper surface of the hanging wing of the shell to prevent the locking piece from being disengaged automatically. The invention has the following beneficial effects: the invention can prevent the container cover from being pressurized again even if additional pressure is generated in the mutually combined state, so that the phenomenon that the locking sheet is automatically disengaged can not occur in any condition.

Description

A kind of airtight container that prevents the locking piece from being disengaged by itself

technical field

The invention relates to a sealed container, especially a sealed container with a sealing pad on the container cover. The container cover and the container shell are pressurized and sealed by means of the locking plate provided on the container cover, and the sealing is carried out by controlling The pressurization depth of the above-mentioned sealing gasket is used to prevent the locking piece connecting the container cover and the housing from disengaging automatically in the buckled state.

Background technique

At present, in order to prevent the sealing gasket of the container cover from falling off by itself, most of the sealed containers are provided with an annular groove of a certain depth on the container cover; The annular flange of the groove is provided with an outwardly protruding hanging wing within a certain distance from the bottom of the above-mentioned flange. A foldable integral or detachable locking piece is arranged on the container cover, so that it can be buckled on the above-mentioned hanging wings.

In order to prevent the locking piece of the container cover from disengaging by itself, it is necessary to apply a certain force, that is, use the locking piece to insert the shell flange into the groove of the container cover and press the gasket to maintain the seal between the shell and the container cover .

But the shortcoming of this device is: when the container lid that gasket is housed is subjected to the pressure from top to bottom, and when this pressure is greater than the pressure that locking plate is used for fastening hanger wing, is originally subjected to first to keep sealing. The sealing gasket under the second pressure will be subjected to the second pressure, and the locking piece will be disengaged from the hanging wing. If you consider that most of the container lids with locking pieces are injection molded with plastic, when the locking piece is disengaged, the locking piece will be lifted upwards, if you want to pick up several containers that have fallen together If it is not found that the container cover has been separated from the housing, the housing will be dropped on the ground, causing unavoidable trouble.

And if when this locking piece and container cap are injected into one, more serious problems will take place.

Contents of the invention

The technical problem to be solved by the present invention is to provide a sealed container that prevents the locking piece from coming off by itself; the present invention sets a stopper in the container cover or the shell to control the pressurized depth of the sealing pad to prevent the container cover from coming off by itself open.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: in the part where the container cover is combined with the container shell through the locking piece, a stopper is provided on the container cover or the container shell, and the stopper is passed through the stopper. Prevents secondary pressure on container lids.

The beneficial effects of the present invention are as follows: even if the present invention generates additional pressure in the state of being combined with each other, the container cover will not be under pressure again, so the locking piece will not be disengaged by itself under any circumstances.

Detailed ways

Referring to shown in Fig. 1-4, the present invention is made up of container lid (10) and container housing (20): an annular groove (11) with certain depth is set on container lid (10), to prevent being contained in container The sealing gasket (30) on the cover (10) falls off automatically, and is also provided with a groove wall (12) for forming an annular groove (11) and a locking piece ( 13). The container shell (20) is provided with a protruding annular flange (21) for inserting into the annular groove (11) of the container cover (10) and an outwardly protruding hanger at a certain distance from the bottom of the annular flange (21). The wing (22) is also provided with a stop platform (40) protruding downward from the bottom of the groove wall (12) forming the annular groove (11).

Wherein, the stop platform (40) protrudes toward the upper end of the hanging wing (22) of the container housing (20), so that it can be close to the groove wall (12) forming the annular groove (11). And only stop platform (40) is located at the part that locking piece (13) and hanging wing (22) combine, or is arranged as integral ring, can reach same purpose.

Moreover, if the stop platform (40) is integrated with the container shell (20) or the container cover (10), it also has the effect of preventing twisting between the container cover (10) and the container shell (20).

Therefore, after the container cover (10) is combined with the container shell (20) by the locking plate (13), if other pressures are generated, the stopper (40) is no longer under pressure, so it can Prevent locking piece (13) from throwing off phenomenon automatically.

In the present invention, the stop platform is arranged on the groove wall of the container cover and the upper end of the hanging wing of the container casing, but it can also be arranged on the inner wall of the container casing or the groove frame according to various molding conditions.

Apparently, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation of the present invention. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. All the implementation manners cannot be exhaustively listed here. All obvious changes or variations derived from the technical solutions of the present invention are still within the protection scope of the present invention.
