The present invention relates to a plastic container, and more specifically, by forming an insulating space in a double structure on the lid of the plastic container that can hold kimchi, etc., the door in a state of storing the plastic container containing kimchi in the storage room of the kimchi storage The present invention relates to a plastic container in which kimchi contained in the plastic container is not affected by the temperature change even if the temperature change due to the opening and closing is severe.

In general, when kimchi is stored in a storage room of a kimchi storage, it is stored in a storage room in a kimchi storage container made in a box shape.

That is, the kimchi storage container 100 is applied to the conventional kimchi storage, as shown in Figure 1, the container body 110 made of a rectangular box shape having an upper portion and an accommodation space therein, and the container The lid 120 is capable of sealing the opened upper surface of the body, and the handle 130 is provided on both upper sides of the container body 110 to hold and transport the user.

Therefore, in the state of containing the kimchi, etc. in the interior of the container body 110 is sealed by engaging the edge portions of the lid 120 in engagement with each other along the upper edge of the opening of the container body 110.

Such a kimchi storage container is generally produced using a plastic material, hereinafter, the kimchi storage container 100 is referred to as a plastic container (100).

Recently, the plastic container applied to the kimchi storage is manufactured as a functional container by mixing ocher and the like in the plastic, and may be designed to obtain a more useful effect in storing kimchi and the like.

As such, plastic containers in recent years tend to be adding additional functions that can exhibit more useful effects in the process of storing kimchi or food, rather than simply storing kimchi or food.

In particular, in the case of kimchi stored for a long time is sensitive to temperature changes, it is very important to maintain a constant temperature in the appropriate storage temperature range to maintain a constant degree of acid oxidation affecting the taste of kimchi.

The kimchi storage is a household appliance made in consideration of the characteristics of kimchi sensitive to temperature changes caused by the long-term storage of kimchi has recently gained a great response to housewives.

In the case of storing kimchi for a long time in the kimchi storage, it is very important to reduce the temperature change on kimchi in the storage room as much as possible.

 However, as shown in FIG. 2, when the user opens the door 200 of the kimchi storage as needed in a state where the plastic container 100 containing kimchi is stored and stored in the storage room 300 of the kimchi storage. Inevitably, a relatively high outside air is forced to flow into the storage room 300 of the kimchi storage, so that the temperature change occurs severely.

In particular, when the door 200 is opened, the outside air introduced into the storage compartment 300 first contacts the lid 120, which is the upper portion of the plastic container 100, so that a temperature change in the lid 120 of the plastic container 100 occurs. Is most likely to occur in the shortest time, through the lid 120 is the outside air is most conducted to the inside of the plastic container.

Therefore, the temperature deviation between the center portion of the plastic container 100 and the outer portion close to the surface is intensified, so that there is a high possibility that the degree of acidity of the kimchi stored in the plastic container 100 is changed for each part, thereby maintaining a uniform taste of kimchi. Considering that one of the important factors to determine the performance of the kimchi storage, it is not preferable that the temperature deviation in the plastic container 100 is not deepened because the insulation from the outside air is not made as described above.

That is, even when the plastic container 100 is in contact with the outside air by opening the door 200 as described above, it is preferable to prevent the outside air from being quickly conducted to the inside of the plastic container 100, but conventional conventional plastic The container 100 had the disadvantage of not having a separate structure that can block the conduction of outside air.

Therefore, the present invention is devised to improve and solve the problems of the conventional plastic container as described above, the object of the present invention by forming a heat insulating space in a double structure on the lid of the plastic container that can be stored, such as kimchi, It is to provide a plastic container so that the kimchi contained in the plastic container is hardly affected by the temperature change even if the temperature change due to the door opening and closing is severe while the plastic container containing the kimchi is stored in the storage compartment.

The present invention for achieving the above object, in the plastic container having a container body having an opening surface for storing kimchi, and a lid for opening and closing the opening surface of the container body, the lid is bent downwardly All parts are formed into a top surface and a bottom surface except for forming a plastic container, which is formed into a double structure having a hollow insulation space sealed inside by a combination of the top and bottom surfaces. Is achieved.

Here, any one of the top and bottom surfaces are injection molded with the edge bent downward through the primary mold, and the other one surface is injected through the mold with the other mold By double injection, the lid can be molded into a double structure.

In addition, the top and bottom surfaces may be separately formed and then combined with each other through ultrasonic fusion, thereby forming a dual structure.

At this time, it is preferable that the upper and lower surfaces are made of a transparent material.

The magnet is inserted into and fixed to one side of the outer circumferential surface of the lid, and when the lid is coupled, the magnet is inserted into and fixed to the outer circumferential surface of the container body, which is a position corresponding to the magnet receiving portion of the lid, respectively. It is preferable that the accommodating portion has a structure correspondingly formed.

In addition, a plurality of grooves may be provided on the inner side of the lower bent edge of the lid, and may have a structure in which a plurality of fitting protrusions are fitted to the grooves to be fitted to the fitting jaw of the container body in contact with the edge.

In particular, it is preferable that a packing member is provided on the inner circumferential surface of the rim of the lid fitted with the top rim of the container body.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 to 5, the plastic container 1 according to the present invention is a container for storing and storing kimchi, etc., not shown in the storage room of the kimchi storage, etc., similar to a conventional plastic container, the top is opened A container body 10 having a box-shaped accommodation space, a lid 20 for opening and closing the opening surface of the container body 10, and a handle provided on both sides of the container body 10 to be held and carried by a user ( 30).

Here, the present invention is characterized in that the lid 20 is formed in a double structure having a heat insulating space (S) therein.

That is, the present invention, as shown in Figures 4 and 5, the lid 20 is formed at the same time all parts except the lower edge 21 is divided into the upper surface (20a) and the lower surface (20b) By the combination of the top surface 20a and the bottom surface 20b is characterized in that it is molded in a dual structure having a hollow insulating space (S) sealed inside.

At this time, the heat insulating space (S) serves to block the outside air conduction to the inside of the plastic container (1) through the lid 20 of the plastic container (1), the inside may be formed of an air layer It may be formed to have a vacuum state, but for more effective thermal insulation it would be desirable to have a vacuum state.

As such, there may be various methods as a method of forming the heat insulation space S by the dual structure by using the lid 20 on the upper and lower surfaces 20a and 20b. For example, the injection method and the ultrasonic fusion method.

In other words, the ultrasonic fusion method is formed by separately forming the upper surface (20a) and the lower surface (20b), respectively, the upper surface (20a) and the lower surface (20b) by combining with each other through ultrasonic fusion is a commonly used technique It is to produce a lid 20 having a structure.

In this case, the upper surface 20a and the lower surface 20b are coupled to each other by ultrasonic welding in a state in which the edge 21 is integrally injection molded on any one of the upper surface 20a and the lower surface 20b. It is desirable to.

And, the method of manufacturing a lid by a double injection method, first, any one of the top surface (20a) and the bottom surface (20b) to be injection molded with the edge 21 bent downward through the primary mold In this way, the lid 20 can be molded into a dual structure by double injection so that the other surface can be coupled to the other surface through the secondary mold to one surface injected with the edge 21.

For reference, FIG. 4 shows that the lower surface 20b and the edge 21 are injection molded through the primary mold, and then the upper surface 20a is coupled to the lower surface 20b through the secondary mold to double injection. 5 shows that the upper surface 20a and the edge 21 are injection molded through the primary mold, and the lower surface 20b is coupled to the upper surface 20a through the secondary mold. This shows the state of double injection.

In particular, the upper surface 20a and the lower surface 20b are both made of a transparent material so that the inside of the plastic container 1 can be seen through the lid 20.

This allows the user to check the contents contained in the plastic container 1 without opening the lid 20, which has the advantage of reducing unnecessary opening of the lid 20 for checking the contents as much as possible, and the lid 20 ) Will have the advantage of reducing the temperature change caused by contact with the outside air in the plastic container (1) as possible to reduce the unnecessary opening of the maximum.

In addition, the plastic container 1 according to the present invention employs various methods to form a double-insulated space S in the lid 20 and to improve hermeticity.

That is, when the cover member 25 is provided on the inner circumferential surface of the edge 21 of the lid 20 to fit the lid 20 along the upper edge of the container body 10, the packing member 25 The sealing effect is to improve the sealing property.

In addition, the magnet receiving portion 22 is formed on one side of the outer circumferential surface of both side edges 21 of the lid 20, and the magnet 23 is inserted into the magnet receiving portion 22 of the lid 20. The lid 20 is fitted to the container body 10 by forming a magnet receiving portion 12 around the fitting jaw 11 of the container body 10, which is a corresponding position, and inserting the magnet 13 therein. When the lid 20 is closed, the magnets 13 and 23 can be tightly sealed by the combination of the magnets 13 and 23.

And, as shown in Figures 6 to 8 showing another embodiment of the present invention, the heat insulating space (S) formed by the upper surface 20a and the lower surface 20b of the lid 20 has a dual structure In addition to having a), the edge 21 of the lid 20 extends downwardly longer than in the related art, and then a plurality of grooves 24 are formed side by side on the inner circumferential surface of the edge 21, and the plurality of By forming the fitting protrusions 14 on the fitting jaws 11 of the container body 10 corresponding to the two recesses 24, the fitting protrusions of the container body 10 when the lid 20 is closed are formed. 14) and the groove 24 of the lid 20 is firmly fixed through the hooking mutually to improve the sealing.

Here, when the lid 20 is closed, a part of the edge 21 of the lid 20 passes through the fitting protrusion 14 formed on the fitting jaw 11 of the container body 10, As shown in FIG. 8, since the edge 21 of the lid 20 has some elasticity, the protrusion 14 of the container body 10 is slightly extended to the outside of the edge 21 of the lid 21. In the process, when the groove 24 and the fitting protrusion 14 are engaged with each other by hooking, the ends of the edges 21 that are opened are elastically restored to be fixed in the initial state.

On the contrary, when the lid 20 is to be opened, the lid 20 may be opened by lightly pulling the edge of the edge 21 to pull the end of the groove 24 and the fitting protrusion 14 in a state where the lid 20 is released. .

As described above, the plastic container 1 according to the present invention can block the intrusion of outside air through the lid 20 through the insulating space (S), it can also significantly improve the sealing of the lid 20 itself. Will be.

That is, as shown in Figure 2 shown in the prior art, assuming that the plastic container 1 according to the present invention is stored in the storage room of the kimchi storage, in the case of opening the door of the kimchi storage When the outside air is introduced into the storage compartment and the outside air contacts the plastic container 1 through the lid 20, the outside air is introduced into the plastic container 1 through the heat insulating space S of the lid 20. Since it blocks the conduction, it is possible to prevent the temperature deviation from deepening in the upper part of the plastic container 1.

As described above, the kimchi accommodated due to the temperature change and the temperature deviation caused by the inflow of outside air has a merit that can partially improve the problem of the degree of acid waste.

The present invention has been described above with reference to the preferred embodiment shown in the drawings, but this is only illustrative and not limited to, those skilled in the art having various modifications and equivalents therefrom Other embodiments would be possible.
