Description

Horizontal airtight vessel }

The present invention relates to an airtight container, and more specifically, to a horizontal airtight container that can improve airtightness and improve the usability of storage space for airtight containers such as refrigerators.

Maintaining the freshness of various foods such as vegetables and fish is very important, and airtight containers are used to keep the food in an unspoiled state until consumed.

In general, an airtight container consists of a container body of various shapes such as square or circular, and a lid that is fastened to the body to be open and closed, and the inside and outside of the container are sealed so that food can be stored in a vacuum state.

For this purpose, when the lid is closed, the containers are closely adhered to each other by a coupling structure formed along the edge of the container body.

As a specific example of an airtight container, Registered Office No. 20-0493173 discloses an airtight container for food storage with a lid that is easy to open and close. Most conventional airtight containers are sealed so that the seal between the container body and the lid is done in the vertical direction. It is composed.

Figure 1 shows an example of another closed container 10 in which the container body 11 and the lid 12 are coupled in the vertical direction, and the top 11 of the container body 11 is formed along the edge of the lid 12. A packing portion 12-1 is formed that is vertically coupled to 1). Accordingly, the lid 12 is covered from above the container body 11, and the upper end 11-1 of the container body 11 is inserted into the packing portion 12-1 formed on the lid 12, thereby sealing the container body 11. .

However, when using this conventional vertical coupling structure, the lid 12 must be made larger than the container body 11 due to the nature of the structure, so more space where the sealed container is stored, such as the inner space of a refrigerator, is used.

In addition, the direction of the coupling surface of the lid 12 and the container body 11 is the same as the direction in which the air inside the container is discharged, making it difficult to maintain the sealing force.

That is, the conventional vertical coupling structure applied to sealed containers has problems that reduce the storage space utilization efficiency of the sealed container and make it difficult to maintain sealing force.
