Food container

Abstract

This invention provides a food container made of a paper sheet with a base portion with four lateral edges connected by folding to the lateral side portions along the folding line. Between each lateral side portion is provided with a side flank which is divided into two portions along the folding line. The outer rim portions of a pair of opposite lateral side portions function as inner cover portions similar in shape to a cut end gable. The outer rim portions of another pair of opposite lateral side portions function as outer cover portions.

1 . A food container comprising a paper sheet with a base portion ( 2 ) with four sides connected by folding to lateral side portions ( 4 ) along the folding line ( 3 ), between each lateral side portion ( 4 ) being provided with a side flank ( 5 ) connected by folding along the folding line ( 3 ), the outer rim portions of a pair of the opposite lateral side portions ( 4 ) functioning as inner cover portions ( 7 ), the lateral side portions ( 4 ) and inner cover portions ( 7 ) on both sides being connected by folding along the folding line ( 3 ), the outer rim portions of another pair of opposite lateral side portions ( 4 ) functioning as an outer cover portion ( 8 ) and outer cover portion ( 9 ), the lateral side portions ( 4 ) and the outer cover portion ( 8 ) along with the outer cover portion ( 9 ) being connected by folding along the folding line ( 3 ) 
 characterized in that the side flank ( 5 ) is divided into two portions by a folding line ( 6 ) into a side flank ( 5   a ) and side flank ( 5   b ), the side flank ( 5   a ) being similar in shape to a trapezoid and the side flank ( 5   b ) being similar in shape to a triangle, both sides of the lateral side portions ( 4 ) on each side being connected to either the side flank ( 5   a ) or side flank ( 5   b ) with the opposite lateral side portions ( 4 ) being connected to the same side flank ( 5 )    
     
     
         2 . A food container according to  claim 1 , wherein the outer cover portion ( 8 ) is similar in shape to a cut end gable with a cutting line ( 10 ) for inserting and attaching a tongue portion  11  of the outer cover portion ( 9 )  
     
     
         3 . A food container according to  claim 1  or  2 , wherein the outer cover portion ( 9 ) is similar in shape to a rectangle with cut angles to conform with the outer cover portion ( 8 ) when inserted and attached together, the outer region of the outer cover portion ( 9 ) being provided with a tongue portion ( 11 ) for inserting into the cutting line ( 10 ) of the outer cover portion ( 8 )
