Airtight container for keeping food

Abstract

The present invention relates to an airtight container for preserving food, and more particularly, in order to make the molding of the container easy, reduce the manufacturing cost of the container while minimizing the fraction defective, and manufacture a tempered glass container which is not broken by collision among containers during production or distribution by making the thickness of the entire container uniform, the present invention provides an airtight container for preserving food comprising a container body wherein a lid with a locking member is detachably coupled on the upper portion on the peripheral surface and a space for food accommodation is provided therein, wherein a stumbling sill 121 with a lateral groove toward the inner direction is formed on the outer surface of the wall 12 of the container body, a side wall of groove 122, which is extended downwardly from the width of the stumbling sill to the outer surface of the wall, is formed on both ends of the stumbling sill, and protruded surface 124 corresponding to the groove depth of the stumbling sill is formed internally in the inner surface of the wall, thereby forming the wall with a uniform thickness.

Description

TECHNICAL FIELD[0001]The present invention relates to an airtight container for preserving food, more particularly, to an airtight container for preserving food, which is easy to manufacture by providing a stumbling sill in the form of a groove on the outer surface of the container wall, instead of the protruded outwardly from the upper end of a container body to which a lid is coupled in the related art, and is able to prevent the container from being damaged during the process of packaging and distribution.BACKGROUND ART[0002]Generally, the airtight containers have been widely used for preserving various foods, for example, side dishes, vegetables, fruits and other raw food materials to be cooked, for a long time. These airtight containers are usually provided with a lid with a built-in packing in the container body to prevent the odors of foods packed therein from being emitted out. The details will be described more specifically referring to the drawings as set forth below.[0003...

AI Technical Summary

Benefits of technology

[0010]The present invention has many advantages. First, a container body can be molded without a protruded part on the outer surface. Further, a stumbling sill to which a lid is coupled is not protruded to the outer surface of the container but is formed so that it is dented inwardly. As a result, the molding process becomes to be easy; the manufacturing cost is reduced thereby lowering unit production cost. Still further, the con

Problems solved by technology

In manufacturing the conventional type of airtight containers 1, the container body 2 is molded along the upper peripheral surface so that supporting corbel 2a can be protruded thus making the molding process very complex.

Further, because the joint groove 2b should be formed on the lower internal surface of the protruded supporting corbel 2a the molding process is very challenging thereby increasing the manufacturing cost.

In addition, there is a high risk of collision during distribution process among the finished products of the conv
