Description

Multi-stage Stacked Containers {STACKING TYPE CONTAINER}

The present invention relates to a multi-stage stacked container, and more particularly, to a multi-stage stacked container in which a plurality of container bodies can be stacked in multiple stages, and at the same time, the container body is easily transported and the locking blade rotates smoothly. It is about.

In general, the container body of the storage container for storing food is molded of synthetic resin, heat-resistant glass, heat-resistant ceramics, etc. of the material approved for food storage, of which the product molded of synthetic resin is easy to mass-produce and price In addition to being inexpensive, it has the advantage of being easy to handle and is the most widely used.

The main body and the cover of the storage container is provided with a locking device to safely store and store food stored in the airtight container and to prevent food leakage.

The container body is provided with a plurality of locking projections projecting outward from the edge of the container body at predetermined intervals along the circumferential direction. In addition, the cover is formed with a locking wing that can be rotated up and down around the blockage, the locking blade is formed with a coupling hole into which the engaging projection of the container body is inserted.

Such a container is rotated by pressing each locking blade of the cover toward the container body in a state of covering the cover of the opening of the container body, and the locking protrusion is elastically inserted into the coupling hole of the locking blade.

However, such a conventional storage container has various problems as follows.

First, there is a problem that the conventional storage container can not be formed in multiple stages. Recently, as the number of meals at home decreases and the number of families decreases, at home, when preparing or cooking food, many foods are cooked little by little rather than a lot of food. Therefore, there are more kinds of food to be stored, in which case, several storage containers are needed rather than the size of the storage container itself. However, when using several storage containers, it takes up a lot of space in the refrigerator. Accordingly, it is necessary to produce a multi-stage container in which several container bodies can be laminated while using only one cover. In addition, in the case where the storage containers are formed to be stacked in multiple stages, the packing should be mounted on each container body as well as a cover to improve the sealing force of each container body. Accordingly, it will be necessary to provide a structure for mounting the packing on the lid and each container body.

On the other hand, the conventional storage container, the locking projection is formed on the container body, the locking blade is provided on the cover, the outer wall of the container body is formed with ribs of the thickness of the cover for seating of the cover. Accordingly, when food is accommodated in the container body and then only the container body is transferred, there is no area to be gripped. Accordingly, the user supports the bottom surface of the container body, or transfers the finger by using a rib as a handle, or even by moving the inner wall and the outer wall of the container body with a finger in the opening area of the container body. In other words, it is too inconvenient for the user to grip and transport the container body. Accordingly, it is necessary to change the structure of the storage container to facilitate the transfer of the container body.

In addition to this, in the related art, as the locking blade is formed as a blockage, there is a closed end such that the rotation is not smooth and the lock wing is separated from the blockage due to the elasticity of the blockage even after being engaged with the locking projection. Accordingly, it is necessary to improve the structure of the locking blade smooth rotation of the lock blade and improved locking performance.

Accordingly, it is an object of the present invention to provide a multi-stage stacked container that allows the multi-stage container body to be hermetically stacked and at the same time facilitates the transfer of the container body and facilitates the rotation of the lock blade.

The multistage stacked container can be laminated in multiple stages by forming a locking projection on the cover and forming a locking wing on the container body, and can improve airtightness by attaching a packing to the cover and the container body.

Hereinafter, a detailed structure of the present multi-stage stacked container will be described with reference to the drawings. In the present embodiment, a circular container will be described, but the claims of the present invention are not limited thereto and may be any shape container.

This multi-stage stacked container includes a single lid 10 and a plurality of container bodies 20, as shown in Figs.

The cover 10 is formed in a substantially circular shape, and a locking area formed in a plane for providing a locking device is provided in an area facing each other with respect to the center of the circle. As shown in FIG. 1, the locking regions may be formed in pairs or in two pairs at mutually opposite positions. The cover 10 is formed of a cover plate 11 for blocking the container body 20, and the side plate 12 extending downward bent from the edge of the cover plate 11, each lock of the side plate 12 In the region, a first catching protrusion 15 protruding from the plate surface of the side plate 12 is formed.

As shown in FIGS. 3 to 4, the first catching protrusion 15 is formed with a first catching jaw 16 protruding upward at an end thereof so as to be engaged with the engaging hole 24 of the locking blade 23. It is. The locking blade 23 is elastically coupled to and released from the first locking protrusion 15 by the first locking jaw 16.

On the other hand, at the edge of the lid 10, a downwardly open channel-shaped receiving groove 17 for receiving the opening edge of the container body 20 is formed, and the receiving groove 17 is provided with a packing 18a. To maintain the airtightness between the container body 20 and the cover 10.

The container body 20 to which the cover 10 is coupled is formed in a cylindrical shape having a locking area formed in a plane so as to correspond to the locking area of the cover 10, and the bottom plate 21 and the side wall plate 22 are formed. Have In the region of the side wall plate 22 spaced apart from the opening of the container body 20, a seating rib (not shown) on which the side plate 12 of the cover 10 is seated protrudes along the circumferential direction. In addition, the container body 20 is formed with a stepped jaw 28 recessed from the lower region of the side wall plate 22 to the bottom plate 21 to form a step with the side wall plate 22. Silver is seated on the opening edge of the other container body 20 coupled to the lower portion of the container body 20, it is possible to be stacked in the container body 20 mutually.

In the locking area of each container body 20, a locking blade 23 coupled to the first locking protrusion 15 and a second locking protrusion 25 to which the locking blade 23 of the other container body 20 is coupled are provided. Formed. The second locking projection 25 is formed just above the stepped jaw 28, and the second locking projection 26 is formed at the end thereof similarly to the first locking projection 15.

The locking blade 23 protrudes from the same line as the seating rib, and can be rotated up and down about the blockage formed in the connection region with the seating rib. The locking blade 23 is formed with a coupling hole 24 to which the first or second locking protrusions 25 are coupled, and the coupling hole 24 is cut to the region of the side wall plate 22 of the container body 20. It is. Accordingly, since no blockage is formed in the region where the coupling hole 24 is formed, the locking blade 23 is smoothly rotated, and the locking blade 23 and the first or second locking protrusion 25 are conventionally formed. When the coupling of the first or second locking projections 25 by the elastic force of the blocking can be prevented from being released from the coupling hole 24 of the locking blade 23.

The container body 20 is classified into two types, depending on the presence or absence of the packing. First, as shown in Fig. 5, the container body 20a in which the packing is mounted, the packing 18b is mounted along the circumferential direction at the opening edge thereof, and the packing 18b is the opening of the container body 20a. It surrounds the orbit. The container body 20a in which the packing 18b is mounted is coupled to the lower part of the other container body 20a, and the stepped gap 28 of the other container body 20a is seated at the opening edge in which the packing 18b is mounted. By doing so, it is possible to maintain the airtight between the container body (20a).

On the other hand, the container body 20b having no packing, as shown in Figure 4, is directly coupled to the cover 10, because the packing 18a is mounted in the receiving groove 17 of the cover 10, The container body 20b does not need a separate packing.

On the other hand, the container body 20 and the cover 10 is provided with a structure capable of seating the container body 20 detached from the cover 10 to the cover 10. First, the bottom plate 21 of the container body 20 has a protruding frame 29 protruding outwardly along the circumferential direction is formed to gently protrude by a predetermined width along the radial direction of the container body 20, the cover ( The cover plate 11 of 10) has a seating frame 19 having a radius that can be in contact with the inner or outer diameter of the protruding frame 29 protrudes upward along the circumferential direction. Accordingly, when the cover 10 is placed on the floor and the container body 20 is seated on the cover 10, as shown in FIG. 4, the seat frame 19 and the container body 20 of the cover 10 are disposed. Protruding frame 29 of the concave and convex to prevent the flow of the container body 20.

Briefly describing the process of using the multi-stage stacked container as follows.

First, food is accommodated in each container body 20, and then each container body 20 is laminated, and the lid 10 is covered with the container body 20 stacked on the top. At this time, the edge of the container body 20b is accommodated in the receiving groove 17 of the lid 10, and the packing of the container body 20a stacked on the lower step jaw 28 of each container body 20a ( 18b). In this state, the locking blade 23 of the container body 20b stacked on the top is rotated and pressed toward the cover 10 so that the first locking projection 15 is elastic to the coupling hole 24 of the locking blade 23. To be combined. Then, the locking blades 23 of each container body 20 are rotated and pressed toward the container body 20 stacked thereon so that each second catching projection 25 is elastically coupled to the locking blades 23. . Then, the airtightness of the container body 20b and the lid 10 is maintained by the packing 18a of the lid 10, and each container body 20 adjacent to each other by the packing 18b of each container body 20a. Confidentiality is maintained.

Thus, the multi-stage stacked container of the present invention, by forming the locking blade 23 and the second locking projection 25 in the container body 20, it is possible to stack the container body 20 in multiple stages. Accordingly, by taking up less storage space, the same relatively large number of containers can be stored. And, by forming the lock wing 23 in the container body 20, the lock wing 23 can be used as a handle to facilitate the transfer of the container body 20. In addition, by attaching packings 18a and 18b to the lid 10 and the container body 20, the airtightness between the lid 10 and the container body 20 and between the container body 20 and the container body 20 is maintained. To prevent food spills.

In addition, by forming the coupling hole 24 of the lock blade 23 to the side wall plate 22 area of the container body 20, the contact area between the blockage and the container body 20 is reduced to rotate the lock blade 23. This becomes smooth and reduces the elastic restoring force of the blocked hinge, thereby preventing the locking blade 23 from being released from the engaging protrusions 15 and 25.

Meanwhile, in the above-described embodiment, the first and second locking protrusions 15 and 25 are formed at the lower portion of the lid 10 and the container body 20, and the locking blade 23 is disposed on the upper portion of the container body 20. Although formed, the lock wing 23 is formed in the lower portion of the lid 10 and the container body 20, and the container body 20 in multiple stages even if the locking projection 25 is formed on the upper portion of the container body 20. Of course, it can be laminated.

On the other hand, in the above-described embodiment, the packing 18b is mounted only on the container body 20a that is not directly coupled to the cover 10, but the cover 10 is formed in the stepped step 28 region of each container body 20. By forming the groove in the same shape as the mounting and the packing, it is possible to maintain the airtight between the lid 10 and the container body 20, the container body 20 and the container body 20. Such an embodiment is the present invention Not claimed in the claims, but will belong to the scope of the present invention.

As described above, according to the present invention, it is possible to stack the airtight in multiple stages, and to provide a multi-stage stacked container that not only facilitates the transfer of the container body but also improves the locking performance.
