Description

Technical Field

[0001] The present invention relates to a food storage container with enhanced fitting force. More specifically, the food storage container with enhanced fitting force comprises: a storage portion, a storage space portion that can store food is formed in a depression at the bottom; and a cover portion that can detachably cover the upper portion of the storage portion, and a combining and accommodating portion is formed at opposing positions on the upper surface of the cover portion of the food storage container, so that the storage portions of other food storage containers stacked on the upper portion can be fitted together by sliding, and a combining and locking portion that can be fitted into the combining and accommodating portion is formed at opposing positions on the bottom surface of the storage portion. After the fitting force between the food storage containers is enhanced and food is stored, not only can the stacked food storage containers be prevented from being easily separated, but the food storage containers can also be easily and quickly stacked and separated. Background Art

[0002] Generally, existing storage containers for storing various transport items are mainly made of plastic synthetic resins and can be used for various purposes such as lunch box containers, egg packaging containers, sandwich packaging containers, etc.

[0003] On the other hand, a storage container for packing fruits in units of quantity has been recently used, which is composed of an upper cover and a lower body made of a polyester material, and has a general structure that can be rotated by a hinge portion at one side.

[0004] This conventional ordinary storage container comprises: a food receiving portion, a plurality of divided space portions for loading contents such as rice or side dishes are formed at the bottom, an extension piece extending outward is formed at the front end, and a first insertion protrusion and a second insertion protrusion are formed on both sides of one end and both sides of the other end of the bottom surface to prevent collapse during stacking; and a cover portion, which covers the upper part of the food receiving portion so that the extension piece is elastically combined with the inner side surface to ensure the sealing of the food and prevent it from being easily separated from the food receiving portion, and a first coupling groove and a second coupling groove are formed on both sides of one end and both sides of the other end of the upper surface to respectively accommodate insertion protrusions protruding from the food receiving portions of other disposable lunch box containers stacked on the upper portion to prevent collapse caused by stacking.

[0005] However, in this existing ordinary storage container, the first insertion protrusion and the second insertion protrusion formed at the corner of the receiving bottom surface are stacked with the first coupling groove and the second coupling groove formed in the cover portion due to being received in the first coupling groove and the second coupling groove, and the receiving portion of the storage container stacked on the upper portion and the cover portion located at the lower portion are stacked without a fitting force. Therefore, not only is it difficult to stack multiple layers, but there is also a problem of easy collapse during the stacking process.

[0006] With this in mind, Korean Patent Application No. 10-2020-0015060 discloses an easily stackable food storage container.

[0007] It is reported that the existing common food storage containers that are easy to stack include: a food storage part, the upper part of which is open so as to store food; and a cover part, which covers the upper part of the food storage part and is used to prevent foreign matter from flowing in and to block the stored food from flowing out. One or more combining protrusions are formed laterally on the upper surface of the cover part, so that the bottom surfaces of other food storage parts stacked on the upper part can be combined by pressurization or sliding. One or more combining grooves are formed on the bottom surface of the food storage part, which can accommodate the combining protrusions formed on the upper surface of the cover part by pressurization or sliding to achieve combination and stacking. A stopper protrusion is also protrudingly formed on one side of one end of the combining protrusion, which can be moved toward the other food storage parts stacked on the upper part. The combining protrusion is inserted into the combining groove side of the bottom surface of the food storage part, and when fastening is achieved by sliding, the stop position can be constantly maintained. The combining protrusion protrudes from the upper surface at the protruding part of the cover plate, and inclined surfaces for combining protrusions are formed on both side surfaces so that it can be combined with the combining groove formed on the receiving plate of other food storage parts stacked on the upper part by pressurization or sliding. The combining groove is formed on the bottom surface of the receiving plate, and inclined surfaces for combining grooves are formed on both inner side surfaces so that the combining protrusions formed on other cover parts located at the lower part can be accommodated by pressurization or sliding to achieve combination and stacking. Expansion parts are also formed on one side and the other side of the combining groove, which allows the combining protrusion to enter easily and quickly.

[0008] However, in the conventional common food storage containers that are easy to stack, since the coupling protrusions formed on the upper surface of the cover are coupled and stacked by slidingly inserting into the coupling grooves formed on the bottom surface of the receiving groove, it is inevitable that the fitting force is reduced. As a result, when the food storage containers storing food are stacked, there is a disadvantage that the food storage containers are easily separated by external force and the stored food is tilted to one side. Summary of the invention

[0009] Technical issues

[0010] In this regard, in order to solve the problems mentioned above, the purpose of the present invention is to provide the following food storage container with enhanced fitting force, which includes: a storage portion, a storage space portion that can store food is formed in a depression at the bottom; and a cover portion that can detachably cover the upper portion of the storage portion, and a combining and accommodating portion is formed at opposing positions on the upper surface of the cover portion of the food storage container, so that the storage portions of other food storage containers stacked on the upper portion can be fitted together by sliding, and a combining and locking portion that can be fitted into the combining and accommodating portion is formed at opposing positions on the bottom surface of the storage portion. After the fitting force between the food storage containers is enhanced and food is stored, not only can the stacked food storage containers be prevented from being easily separated, but the food storage containers can also be easily and quickly stacked and separated.
