Hereinafter, the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a perspective view illustrating a configuration of a closed container according to an embodiment of the present invention. FIG.

The closed container according to the present embodiment is composed of a main body 100 and a lid 200 which are provided for storing and storing contents such as foods, preventing the stored contents from leaking, and maintaining the freshness of the contents .

The main body 100 is partially opened to allow food to be carried in or out, and to store the carried food, and a part of the opened part is sealed by the lid 200.

The body 100 is provided with a projection 110 and a seat 120 for engagement with the lid 200.

The protrusion 110 is provided to enable the lid 200 to be coupled to the main body 100 and is coupled to the coupling portion 210 described later.

The protruding portion 110 is disposed at the uppermost position of the main body 100 and protrudes by a predetermined height. The predetermined height is defined as a distance between the protruding portion 110 and the fastening portion 210, It means height that can not be.

The seating part 120 prevents the lid 200 coupled with the protrusion 110 from being coupled with the protrusion 110 beyond a predetermined depth and allows the lid 200 coupled with the protrusion 110 to be seated .

To this end, the seating part 120 is provided on the outside of the main body 100 and is positioned at the lower end of the projection part 110.

The height of the protruding portion 110 and the height of the coupling portion 210 to be described later are equal to each other to prevent the protruding portion 110 from being coupled with the protruding portion 110. [ But may not be completely identical in the process of injecting the main body 100 or the lid 200. In this case,

The protruding portion 110 and the fastening portion 210 may be formed to have a height equal to the height of the fastening portion 210 if the fastening portion 210 is not provided in a state where the height of the protruding portion 110 is smaller than the height of the fastening portion 210 When the fastening part 210 is coupled with the protruding part 110 beyond a predetermined depth, an excessive external pressure is required when the lid 200 is separated from the main body 100.

However, since the closed container according to the present embodiment is used for facilitating the loading and unloading of the contents, if a large external pressure is required to join or separate the main body 100 and the lid 200, It is inconvenient.

For this reason, the seating part 120 according to this embodiment is provided to prevent the lid 200 coupled with the projection 110 from being coupled with the projection 110 beyond a predetermined depth.

Meanwhile, the lid 200 is coupled with the main body 100 to prevent leakage of contents to the outside of the main body 100 to prevent the contents from being exposed to the outside, and to maintain the freshness of the contents.

The lid 200 includes a fastening portion 210, a lid 220, a protrusion 230, a pressing portion 240, and a handle 250.

The coupling part 210 is provided to engage the lid 200 with the main body 100 and is coupled to the lid 200 when an external pressure is applied to the main body 100 to attach the lid 200 to the main body 100.

The fastening portion 210 may be formed to have the same height as the protruding portion 110 for sealing the main body 100.

In addition, the fastening part 210 is provided at a predetermined angle with the lid part 220, which will be described in detail later with reference to FIG. 2 and FIG.

Meanwhile, the lid 220 is provided so that when the coupling part 210 is coupled with the protruding part 110, the contents are blocked from the outside.

The concave and convex portion 230 is provided between the coupling portion 210 and the lid portion 220 and includes a plurality of concave portions 231 recessed to a predetermined depth and a plurality of convex portions 233 protruding at a constant height.

The concave and convex portions 230 are provided to provide a restoring force to be drawn into the main body 100 by the external pressure applied when an external pressure is applied to the lid 200 for coupling with the main body 100. [

For example, when external pressure is applied to the lid 200, the lid 200 is coupled to the main body 100 by pressure. In this process, the lid 200 is bent and bent toward the inside of the main body 100 Particularly, when the lid 200 is provided in a simple plate shape, the lid 200 is deformed by repetitive external pressure during long-term use.

However, if the concave and convex portions 230 are provided, if the external pressure is applied to the lid portion 220, the gap between the plurality of concave portions 231 or the plurality of convex portions 233 may be increased before the lid portion 220 is bent. The width of the irregular portion 230 becomes larger than when the external pressure is not applied.

However, if the coupling between the fastening part 210 and the protruding part 110 is completed and the external pressure is released, the interval between the plurality of recesses 231 or the interval between the plurality of convex parts 233 returns to the initial interval, It can be restored to its original form.

This will be described later in more detail with reference to FIG.

On the other hand, the pressing portion 240 is provided to uniformly transmit an external pressure for coupling the fastening portion 210 and the protruding portion 110 to the fastening portion 210.

To this end, the pusher 240 is positioned at the center of the lid 220.

Specifically, when external pressure is applied to the pressing portion 240 while the lid 200 is placed on the upper portion of the main body 100 to be coupled to the main body 100, when the pressing portion 240 is pressed by the external pressure, 210 are coupled to the protrusions 110 by the external pressure.

The handle 250 is provided to detach the lid 200 coupled to the main body 100 from the main body 100.

The handle 250 is connected to one end of the fastening part 210 as shown in FIG.

When an external pressure for separating the main body 100 from the lid 200 is applied in the state where the main body 100 and the lid 200 are coupled to each other, an external pressure for separating the handles 250 is transmitted to the fastening part 210 So that the engagement with the protrusion 110 can be released.

FIG. 2 is a cross-sectional view illustrating a state in which the lid 200 is not engaged with the main body 100 according to an embodiment of the present invention. FIG. 3 is a cross- FIG. 4 is a cross-sectional view illustrating a state in which the lid 200 is coupled with the main body 100 according to an embodiment of the present invention. And Fig. 5 is an enlarged view provided to explain more specifically the state in which the lid according to another embodiment of the present invention is combined with the main body.

2 to 5, the description will focus on the fastening part 210, the lid part 220 and the concave / convex part 230 which are deformed according to the state in which the lid 200 is detached or coupled with the main body 100 .

2, the fastening portion 210 and the lid 220 are formed at a first angle A in a state where the lid 200 is not engaged with the main body 100. [

The angle formed by the coupling part 210 of the lid 200 coupled to the main body 100 and the lid part 220 of the conventional hermetically sealed container is set such that when the coupling part 210 is engaged with the projection part 110, And the lid 220 are formed to be equal to each other.

However, the angle formed by the coupling part 210 and the lid part 220 is equal to the angle formed by the protrusion part 110 and the lid part 220 when the coupling part 210 is coupled with the projection part 110 There is a problem that leakage of the contents stored in the main body 100 occurs due to the space formed between the protruding portion 110 and the coupling portion 210.

In order to prevent the leakage of the contents and to improve the adhesion with the protruding part 110 in the fastening part 210, a separate packing member made of a rubber material is provided. However, if a separate packing member is provided, There is a problem that the packing member is not easily cleaned.

Therefore, in order to solve the above-mentioned problems, the present embodiment does not provide a separate packing member. In order to improve the sealing force of the hermetically sealed container without a separate packing member, the fastening portion 210 and the lid portion 210 And the concave and convex portions 230 are formed between the coupling portion 210 and the lid portion 210. [

2, the fastening part 210 and the lid part 210 are formed at a first angle A in a state where the lid 200 is not engaged with the main body 100, When the main body 100 is coupled with the main body 100, the main body 100 is closed by the restoring force that the coupling part 210 and the lid part 210 form the first angle A. [

3, when the lid 200 is coupled to the main body 100, the angle formed by the coupling part 210 and the lid part 210 is smaller than the first angle A by a second angle B ).

4, by the restoring force to achieve the first angle A with the lid 220, even though the fastening part 210 is engaged with the protruding part 110, The sealing force of the hermetically sealed container can be improved while being in close contact with the protruding portion 110 at the opening E of the hermetically sealed container.

The first point D in the present embodiment is formed such that the upper end of the inner surface of the coupling part 210 facing the inner surface of the protrusion 110 when the coupling part 210 is coupled with the protrusion 110 as shown in FIG. And the upper end of the inner surface of the protrusion 110 facing the inner surface of the protrusion 110 is in contact with the inner surface of the protrusion 110.

The second point E in the present embodiment is formed such that the lower end of the inner surface of the coupling part 210 facing the outer surface of the protrusion 110 and the lower end of the coupling part 210 And the lower end of the outer surface of the protruding portion 110 facing the inner surface of the protruding portion 110.

As shown in the drawing, the fastening portion 210 and the protruding portion 110 are brought into contact with each other at the first point D and the second point E, thereby blocking the leakage of the contents stored in the main body 100.

3, when the coupling part 210 is coupled with the projection part 110, the gap between the concave parts 231 or the space between the convex parts 233 is smaller than the coupling part 210 And becomes narrower when not engaged with the protruding portion 110.

The concave and convex portions 230 are formed so that a tensile force to return to the gap between the concave portions 231 or the space between the convex portions 233 when the coupling portion 210 is not engaged with the projected portion 110, The tightening part 210 is brought into close contact with the inner surface of the protruding part 110 due to the tensile force, so that the sealing force of the hermetically sealed container can be improved.

5, arrows positioned on the concave / convex portions 230 represent the tensile forces generated to maintain the initial intervals between the recesses 231 of the concave / convex portions 230 or the interval between the convex portions 233.

The area of the cover 220 and the protrusions 230 may be greater than or equal to the area of the top of the main body 100 formed by the protrusions 100, The tensile force generated in the concave-convex part 230 after the coupling part 110 and the coupling part 210 are combined can be strengthened to further improve the sealing performance.

The closed container according to one embodiment or another embodiment is configured such that the protrusion 110 and the fastening portion 210 are brought into close contact with each other at at least two points D and E as shown in Fig. 4, so that the contents of the main body 100 do not leak As shown in FIG. 5, the lower end of the inner surface of the protruding portion 210 is in close contact with the coupling portion 210 due to the tensile force of the protruding portion 230 as well as the two points D and E, .

As described above, the fastening part 210 and the protruding part 110 come in close contact with each other at a plurality of points, and the restoring force that the fastening part 210 and the lid part 220 form the first angle A, Since the sealing force of the hermetically sealed container is improved by the tensile force generated in the concave and convex portions 230 when the lid 200 is engaged, no separate packing member is required, so that the sealing member can be easily cleaned .

6 is a cross-sectional view illustrating a process in which the lid 200 is engaged with the main body 100 according to an embodiment of the present invention.

6, the large arrows shown on the upper part of the pressing part 240 indicate an external pressure for allowing the lid 200 and the main body 100 to be coupled to each other, And the lid 200 is drawn into the main body 100. FIG.

The portion indicated by the dotted line is a shape of the lid 200 for explaining a state where the lid 200 is coupled with the main body 100 until the external pressure is released. The fastening portion 210 and the recessed portion 230 are, Expressed in solid lines.

When the external force is applied to the pressing portion 240 in a state where the coupling portion 210 is positioned at the upper end of the projection 110, the coupling portion 210 is coupled with the projection 110 by external pressure.

The concave and convex portions 230, the cover portion 220 and the pressing portions 240 are drawn into the main body 100 by a predetermined depth as the concave and convex portions 230 are expanded by the external pressure.

The predetermined depth means the depth within a range allowed by the elastic limitations of the lid 220, the concave and convex portions 230, and the pressing portion 240.

At this time, as soon as the lid 200 is drawn into the main body 100, the air located inside the main body 100 passes through between the protruding portion 110 and the coupling portion 210, And is discharged to the outside.

In the illustrated example, arrows indicated by a solid line toward the outside of the main body 100 are for expressing the exhaust of air. As shown in the figure, the air filled in the main body 100 is discharged to the outside of the main body 100 by external pressure As the amount of air located in the closed main body 100 decreases while discharging, the oxidation of the contents can be reduced, and the freshness of the contents can be maintained.

In addition, the inside of the main body 100 may be in a vacuum state through the discharge of air.

Although not shown in the drawing, when the external pressure is released, the cover 220 is rotated by the restoring force to return to the interval when the space between the concave portions 231 or the space between the convex portions 233 is not engaged with the main body 100, The concave and convex portions 230 and the pushing portion 240 are drawn out from the inside of the main body 100 and the angle formed by the lid portion 220 and the concave and convex portions 230 forms the second angle B. [

In this embodiment, the first point D and the second point E are assumed to be specific points. However, this is merely an example for convenience of explanation, and the shape of the fastening portion 220 and the protrusion 110 It is needless to say that the point at which the fastening part 220 and the protruding part 110 abut each other can be changed at any time.

The main body 100 is prevented from slipping on the upper part of the lid 200 when the main body 100 is stacked on the lid 200 as shown in the figure, A non-slip portion may be further provided at a position corresponding to the recessed portion 230 and the pressing portion 240. [

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention.
