Abstract

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

The present invention relates to a sealed container, in particular the body is made of stainless and the lid is formed of a transparent plastic to have a locking function.

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

Conventionally, a sealed container made of a metal body and a plastic lid has a problem in that the sealing force is weak because it is impossible to process to have a locking function due to the material properties of the body, and the lid is made of a close contact structure by simple pressurization.

All. The gist of the solution of the invention.

Therefore, the present invention is intended to have a locking function between the metal body and the plastic lid by combining the frame end of the metal body by separately molding the edge end member, the locking means is formed on the frame end of the metal body.

la. Important uses of the devise.

Airtight containers such as food.

Description

A metal airtight container having a plastic lid with four locking devices}

The present invention relates to a metal hermetically sealed container to be locked with a plastic lid, in particular, the locking means formed integrally with the lid is to be locked while engaging the engaging protrusion formed on the metal body.

Conventionally, the locking means is integrally formed on the plastic lid to be locked by the coupling with the main body, as shown in FIG. 5, as shown in FIG. 5, the bobbin is formed by the coupling protrusion and the lid is provided with the locking means formed with the coupling groove. It was possible.

However, the disadvantage of such a container has a negative side even if the container body is discolored by the contents stored in the plastic body or if the plastic material that is harmless to the human body is used due to the negative image of the environmental hormone unique to the plastic.

In addition, in the prior art, there were ones provided with locking means using stainless steel. However, the disadvantages of this are that the contents are not visible and that a separate welding means or a coupling means is required when manufacturing the same.

Therefore, these stainless steel containers are commercially available as a very expensive product is impossible for the general public.

Therefore, in recent years, a container for allowing a transparent plastic lid to be bonded to a stainless steel body is commercially available, but this is a disadvantage that the lid is merely inserted into the body by pressing and there is no locking function.

In order to have a locking function on the container body of the stainless steel, the stainless steel body implements the container by tapping the stainless flat plate by the drawing method of the press, thereby implementing the engaging protrusion protruding to the side of the container body or the upper edge. This is because it is impossible to implement a coupling protrusion in the.

Therefore, the edge end member in which the engaging protrusion is formed on the stainless steel frame of the present invention is to be molded separately from the plastic so as to be combined with the locking means formed with the coupling groove of the lid.

Explanation of symbols on the main parts of the drawing

10: lid 11: lock wing

20: container body 30: edge end member

31: binding protrusion 32: coupling portion

Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention. First, in describing the drawings, the same reference numerals are used to refer to the same elements even though they are shown in different drawings.

As shown in FIGS. 1 to 3, the present invention is provided with a locking wing 11 which is integrally folded on the transparent plastic lid 10, and a locking means 11a is provided on the locking wing 11. The container body 20 coupled to the 10 is processed by a stainless steel plate by pressing the upper edge end is curled in a U-shape, and the edge end member 30 in which the binding means 31 is formed in the U-shaped curled portion. ) Is molded separately from the plastic, and the contact surface 32 of the edge end member 30 is inserted into the U-shaped inner side of the edge of the container body 20 while the lower end of the U-shape is rolled and the edge end member is coupled. Losing composition.

At this time, the binding means 31 formed on the edge end member 30 is protruded to maintain a predetermined interval or protrude integrally in accordance with the locking means (11a) of the locking blade (11) formed on the lid (10). To lose.

In addition, the fastening means 31 is formed with a fastening protrusion 31a protruding downward so as to be caught by the locking means 11a formed on the locking blade 11 of the lid 10 so that the locking state is not easily released. will be.

In addition, the front end of the contact surface 32 of the rim end member 30 is pressed in the U-shape in the state of being embedded in the U-shape of the container body 20, the U-shaped end is curled while the rim end member 30 In order to fix the curved protrusion 33 is formed in the U-shaped indented state in the pressurized state the edge end member 30 will not be detached.

On the other hand, at the edge of the lid 10, the coupling inlet 12 for inserting the edge of the container body 20 and the packing 13 for inserting and fixed to the coupling inlet 12 is tight Of course it is formed.

Therefore, the sealed container of the present invention configured as described above is to lock the locking means (11a) is formed on the lid 10 is engaged with the binding means 31 mounted on the edge end member of the container body, such a locking function, The function is that the synthetic resin cover made of stainless steel is simply combined with the container body made of stainless steel, so that it is possible to provide simple assembly and low price.

As described above, the sealed container of the present invention is formed with a locking device for fixing the container and the lid to solve the problem of a decrease in the sealing force generated in the conventional sealed container made of a plastic lid and a metal container.
