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.

1 . 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.   
     
     
         2 . The airtight container according to  claim 1 , wherein coupling protrusion  123  is protruded downwardly in the outer portion of the stumbling sill  121 .
