Description

Airtight Containers {AIRTIGHT CONTAINER}

In general, various types of sealed containers are used to keep foods and the like intact and to prevent the smell of foods from leaking out. Such a sealed container is made in various sizes and shapes according to its purpose, but generally includes a receiving portion for receiving food, a lid abutting the upper edge of the receiving portion, and an elastic sealing member on the lower surface of the lid. A predetermined number of engaging members are provided on the outer periphery, and the coupling members are attached to and detached from the accommodating portion so that the lid is brought into close contact with the accommodating portion. In such a conventional hermetic container, the coupling member is elastically coupled to the protrusion formed on the outer circumferential surface of the receiving portion.

The airtight container and the lid are usually made of the same material, but the sealing member arranged on the lower surface of the lid is generally made of a separate material in order to have elasticity. Therefore, it is common that the groove into which the sealing member is inserted is formed at the position where the sealing member is arranged on the outer circumference of the lid.

By the way, during the use of such a sealed container, especially when storing food with a lot of moisture, food may seep into the gap between the sealing member and the groove. Therefore, when washing the airtight container, especially the lid with a cleaning agent, it is preferable to remove the sealing member from the lid and wash it to the separated sealing member and the inner surface of the groove.

However, since the depth of the groove formed in the portion into which the sealing member is inserted is usually larger than the height of the sealing member so that the sealing member is completely inserted, there is a problem in that the sealing member cannot be easily separated by a finger or the like. .

The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to provide a sealed container that can easily separate the sealing member from the lid for cleaning the sealed container.

The airtight container of the present invention for achieving the above object, including a bottom portion and the side wall portion to form a space in which food and the like is accommodated and the upper surface is open; A lid covering an upper surface of the accommodation portion; A coupling member for coupling the accommodation portion and the lid to each other in a sealed state; A groove portion formed at an edge portion of a lower surface of the flat portion of the lid so as to correspond to an upper edge of the side wall portion of the accommodation portion; A sealing member inserted into the groove part; And at least one cutout portion formed at an edge portion of sidewalls forming a groove portion of the lid.

The accommodating portion and the lid may be formed in a rounded quadrangular vertex portion as a whole, and the cutout may be formed in a rounded vertex portion of an inner side wall or an outer side wall among the sidewalls forming the groove portion of the quadrangular lid. .

In addition, the sealing member is preferably formed of a hollow rubber material.

In addition, the cutout is preferably formed to a depth to expose a portion of the sealing member inserted into the groove portion.

In addition, the sealing member, it is preferable to further include a projection projecting to the side to be inserted into the incision.

In addition, the protrusion is preferably protruded more than the thickness of the side wall forming the groove portion into which the sealing member is inserted.

In addition, the protrusion is preferably formed stepped from the side of the sealing member.

The protrusion is preferably formed so that the thickness at the upper end of the cutout is the same as the thickness of the side wall forming the groove, and becomes thicker as it descends.

According to the sealed container of the present invention, there is an effect that can easily separate the sealing member from the lid for washing the sealed container.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of this embodiment, the same name and the same reference numerals are used for the same configuration, and additional description thereof will be omitted.

1 is an exploded perspective view of a sealed container according to an embodiment of the present invention, Figure 2 is a perspective view showing only the bottom of the lid in FIG.

The airtight container according to the present invention forms a space in which food and the like is accommodated, and a receiving portion 30 having an open top surface, a lid 10 covering the upper surface of the receiving portion 30, and a receiving portion 30 and It includes a coupling member 17 for coupling the lid 10 to each other in a sealed state.

Here, the flat plate portion 11 forming the lid 10 corresponds to a portion covering the open upper surface of the receiving portion 30.

In the present embodiment, as shown in FIG. 1, the coupling member 17 is rotatably mounted to the lid 10, and a plurality of coupling holes 18 are provided at the center of the coupling member 17. Formed. The coupling hole 18 is formed to be coupled to each other by inserting a plurality of engaging projections 35 protruding to the outer surface of the side wall portion 32 of the receiving portion 30, as will be described later.

The accommodating part 30 includes a bottom part 31 forming a flat bottom surface and a side wall part 32 extending vertically to surround the edge of the bottom part 31. In the present embodiment, the shape of the bottom part 31 of the receiving part 30 is generally rectangular, but may be manufactured to have various shapes such as polygons or circles. In addition, when this bottom part 31 forms a rectangle, it is preferable to produce the vertex part in round shape instead of making an angular shape. If the bottom portion 31 has a circular shape, the side wall portion 32 will also be formed in a cylindrical shape, and in this case, the portion where the coupling member 17 is attached to the lid 10 is formed in a straight line to form a coupling member. 17 will be rotatable relative to the lid 10.

A groove 13 is formed at a portion corresponding to the upper edge portion of the accommodating portion 30 at an edge portion of the lower surface of the flat portion 11 of the lid 10, and elasticity is provided in the groove portion 13. Sealing member 20 is inserted. The sealing member 20 is preferably formed to fit snugly or forcibly fit into the groove 13 and, of course, should be manufactured to have the same shape as that of the groove 13.

In addition, the lid 10 and the receiving portion 30 are mostly made of a plastic material, the sealing member 20 interposed therebetween for sealing the lid 10 and the receiving portion 30 is more elastic than the plastic material It is preferable to manufacture with rubber which is a big material. In addition, although not shown in cross-sectional view or the like, when the sealing member 20 is formed in a hollow shape, the elastic modulus is made smaller so that the lid 10 is covered with the receiving portion 30 and the coupling member 17 is closed. The sealing property can be made better.

At least one cutout 40 is formed at a corner of sidewalls forming the groove 13 of the lid 10. In addition, the accommodating part 30 and the lid 10 are formed in a quadrangular rounded corner portion as a whole, and the cutout portion 40 is formed of the sidewalls forming the groove part 13 of the lid 10 formed in the rectangular shape. It is preferably formed at the rounded vertex portion of the inner wall 14 or the outer wall 15.

If the lid 10 is not rectangular but circular, it will be appreciated that the cutout 40 is formed between the coupling members 17 attached to the lid 10. Of course, the coupling member 17 may be attached to the receiving portion 30, in which case the position where the cutout 40 is formed will not be limited between the coupling members 17.

1 and 2, a cutout portion 40 is formed at a vertex portion of the outer wall 15 among the sidewalls forming the groove portion 13 of the lid 10. In the lid of FIG. 2, the heights of the inner sidewall 13 and the outer wall 14 are shown the same, but they may be formed differently. In the case where the heights of the inner wall 13 and the outer wall 14 are differently formed, it is preferable that the cutout 40 is formed on the sidewall of which the height is higher, and the sealing member is formed from the lid 10. It will be appreciated that it is easier to separate (20).

Preferably, the cutout 40 is formed to have a depth at which a part of the sealing member 20 inserted into the groove 13 is exposed, and more preferably about half of the height of the sealing member 20 is exposed. Is formed. When the sealing member 20 is compressed when the lid 10 and the receiving portion 30 are compressed, the grooves 13 must be supported, and the depth of the cutout 40 is exposed so that the sealing member 20 is exposed beyond the height of the sealing member 20. If it is made too large, the sealing member 20 is not supported at all in the cutout 40 so that the deformation of the sealing member 20 is severe and sealing may not be performed properly. In addition, when the depth of the cutout 40 is too small and the portion where the sealing member 20 is exposed is small, the portion of the sealing member 20 exposed through the cutout 40 is gripped and the sealing member 20 is recessed. 13) it becomes difficult to extract. Therefore, as described above, it is preferable to form the cutout 40 so that the sealing member 20 is exposed to a medium height.

3 is a perspective view showing a sealing member according to another embodiment of the present invention. The illustrated sealing member 20 further includes a protrusion 50 protruding laterally at a corresponding position to be inserted into the cutout 40 when inserted into the groove 13.

The protrusion 50 is formed to match the shape of the cutout 40, that is, to match the thickness of the outer wall 15 and to have a shape corresponding to the portion cut off from the outer wall 15, so that the protrusion can be viewed from the outside. The outer surface of the 50 is formed to continuously connect with the outer surface of the outer wall (15).

4 is a perspective view showing a lid according to another embodiment of the present invention. In the illustrated lid 10, as in the above-described embodiment, a groove 13 into which the sealing member 20 is inserted is formed at the edge of the flat plate 11. In this embodiment, the cutout 40 is formed at two vertex portions of the inner wall 14 which are generally rectangular. In this case, as shown in FIG. 5, it will be understood that the protrusions 50 formed on the sealing member 20 should protrude to the side from the inner side of the sealing member 20.

Although not shown in the drawings, when the coupling member 17 is rotatably mounted to the lid 10 through the hinge, the outer wall 15 forming the groove portion 13 is formed from the inner wall 14. It is preferable to form relatively thick and to form the height of the inner side wall 14 among the inner side wall 14 and the outer side wall 15 higher than the outer side wall 15. Therefore, in this embodiment, it is preferable that the cutout portion 40 is formed in the inner wall 14, and in particular, the cutout portion 40 is formed in two vertex portions facing the inner wall 14. As shown in FIG.

6 shows a state in which the sealing member 20 as shown in FIG. 3 is inserted into the groove 13 of the lid 10 in which the cutout 40 is formed, as shown in FIG. An enlarged perspective view. Here, the protrusion part 50 is formed to have the same thickness as that of the outer side wall 15 in FIG. 6, that is, the side wall in which the cutout is formed among the sidewalls forming the groove part 13 into which the sealing member 20 is inserted. Therefore, when viewed from the outside, the outer surface of the protrusion 50 and the outer surface of the outer wall form a continuous smoothly curved surface.

The thickness of the protrusion 50 may be thicker than the thickness of the side wall forming the groove 13 into which the sealing member 20 is inserted. In other words, as shown in FIG. 7, the end of the protrusion 51 is formed to protrude more than the outer surface of the outer wall 15, so that the protrusion 51 of the sealing member 20 is held by hand and separated more easily. You can do it.

In addition, as shown in FIG. 8, the height of the protrusion 52 may be lower than the height of the cutout 40 without being the same as the vertical height of the cutout 40. In addition, the protrusions 52 may be formed stepped from the side surfaces of the sealing member 20. In other words, the protrusion 52 is formed in the cutout 40 at the same height as the cutout, and only the portion protruding more than the outer surface of the outer wall 15 is lower than the cutout height so that the protrusion 52 is stepped. It can be formed. As a result, when the height of the protrusion 52 is smaller than the height of the cutout 40, the protrusions 52 are formed to be spaced apart from the upper end of the cutout 40. Here, the upper end of the cutout 40 refers to the edge of the top or top surface of the cutout 40 in a state in which the lid 10 is placed as shown in FIG. 1.

As shown in FIG. 9, the thickness of the protrusion 53 at the upper end of the cutout 40 is equal to the thickness of the side wall forming the groove 13, and becomes thicker as it descends. It may be formed to be. In this case, since the curved surface of the protrusion 53 is in contact with the finger, it is easier to catch and the separation operation becomes easier.

Although the preferred embodiment of the present invention has been described above, the scope of the present invention is not limited only to this specific embodiment, and those skilled in the art are appropriately within the scope described in the claims of the present invention.
