Anti-leak food box

Abstract

The food box contains a box member and a cover member. The box member has a storage space with a top opening. At least a box flange extends from the top opening's circumference. An upward extending anti-leak wall surrounds the top opening. At least a first connection element is configured along the anti-leak wall. The cover member seals the top opening, and has at least a cover flange extending laterally from the cover member's circumference. An upward extending anti-leak ditch surrounds the circumference of the cover member compatible with the anti-leak wall. At least a second connection element is configured along the anti-leak ditch. When the cover member seals the box member, the anti-leak wall is embedded into the anti-leak ditch so as to prevent a content of the food box from leaking.

1 . A food box, comprising:
 a box member having a storage space with a top opening, a box flange extending laterally outward from a section of the top opening's circumference, and an upward extending anti-leak wall surrounding the top opening, where a plurality of first connection elements are configured along and on the anti-leak wall, and each first connection element is located at a corner of the anti-leak wall; and   a cover member for sealing the top opening, the cover member having a cover flange extending laterally outward from a section of the cover member's circumference, and an upward extending anti-leak ditch surrounding the circumference of the cover member compatible with the anti-leak wall, where a plurality of second connection elements are configured along and on the anti-leak ditch, and each second connection element is located at a corner of the anti-leak ditch corresponding to a first connection element;   wherein the first and second connection elements have compatible block shapes; a first fastener is configured along laterally outward facing sides of each first connection element; a second fastener is configured along laterally outward facing sides of each second connection element; the first and second fasteners are indentations of compatible cross-sectional shapes substantially as the numeral 3; the first and second fasteners are configured in an upper section, a middle section, or a lower section of each first connection element and each second connection element, respectively.   
     
     
         2 .- 4 . (canceled) 
     
     
         5 . The food box according to  claim 1 , wherein, when the cover member seals the box member, the anti-leak wall is embedded into the anti-leak ditch so as to prevent a content of the food box from leaking. 
     
     
         6 . The food box according to  claim 5 , wherein the anti-leak ditch has an inverted U-like sectional shape. 
     
     
         7 . The food box according to  claim 1 , wherein the box member and the cover member have compatible geometric shapes. 
     
     
         8 . The food box according to  claim 1 , wherein the first fastener is further configured along outer circumferential side of the anti-leak wall; and the second fastener is further configured along outer circumferential side of the anti-leak ditch.
