Introduced in sandwich packing

Abstract

The present invention relates to improvements related to sandwich packing to reduce costs and to make more practical and hygienic the consumption of food. The packing has a superior housing ( 2 ) and an inferior housing ( 3 ) coupled together by an inferior male lip ( 4 ) and a superior female lip ( 5 ) which are interrupted, but joined together, by a flexible fold ( 6 ). The inferior part ( 3 ) has a cut line ( 7 ) to allow its division in two parts ( 3 A and 3 B). When joined, the superior and inferior housings form a similar contour of a sandwich.

1 . A sandwich packaging for containing a food product comprising:
 a superior housing defining a superior chamber adapted for at least partial enclosure of a food product;   an inferior housing defining an inferior chamber adapted for at least partial enclosure of a food product;   said superior chamber and said inferior chamber being contoured to matingly engage each other and said food product, said superior housing having a superior female lip and said inferior housing having an inferior male lip, said superior female lip formed for matingly engaging said inferior male lip at a fitting section of said superior and inferior housings, said inferior housing having a single perforated line intersecting said inferior male lip and passing through a sidewall of said inferior housing for releasing a first section of said sidewall to expose at least a portion of said food product contained therein when said inferior housing is separated from said superior housing.   
   
   
       2 . The sandwich packaging for containing a food product as claimed in  claim 1 , wherein said superior housing and said inferior housing form a substantially semi-circular cross-sectional contour. 
   
   
       3 . The sandwich packaging for containing a food product as claimed in  claim 2 , wherein said substantially semi-circular cross-sectional inferior housing is truncated forming a flat inferior base member. 
   
   
       4 . The sandwich packaging for containing a food product as claimed in  claim 2 , wherein said substantially semi-circular cross-sectional superior housing is truncated forming a flat superior base member. 
   
   
       5 . The sandwich packaging for containing a food product as claimed in  claim 1 , wherein said single perforated line is substantially located central to opposing ends of said inferior housing. 
   
   
       6 . The sandwich packaging for containing a food product as claimed in  claim 5 , wherein when said inferior housing is severed along said single perforated line, said inferior housing is broken into a pair of substantially equally contoured inferior division portions. 
   
   
       7 . The sandwich packaging for containing a food product as claimed in  claim 1 , wherein said single perforated line extends longitudinally around the entirety of said inferior housing. 
   
   
       8 . The sandwich packaging for containing a food product as claimed in  claim 1 , wherein said superior lip portion snappingly engages with said inferior lip portion. 
   
   
       9 . The sandwich packaging for containing a food product as claimed in claim l, wherein said superior female lip and said inferior male lip are being formed substantially around the periphery of said superior housing and said inferior housing 
   
   
       10 . The sandwich packaging for containing a food product as claimed in  claim 1 , wherein said inferior male lip has a notch intersecting with said single perforated line for ease of tearing along said perforated line. 
   
   
       11 . The sandwich packaging for containing a food product as claimed in  claim 1 , wherein said superior female lip has a protrusion. 
   
   
       12 . The sandwich packaging for containing a food product as claimed in  claim 11 , wherein said protrusion of said superior female lip overlaps said notch of said inferior male lip. 
   
   
       13 . The sandwich packaging for containing a food product as claimed in  claim 1 , wherein said sandwich packaging has a tab having opposing ends respectively attached to said superior and inferior housings. 
   
   
       14 . The sandwich packaging for containing a food product as claimed in  claim 13 , wherein said tab couples said superior housing and said inferior housing to each other at said fitting section. 
   
   
       15 . The sandwich packaging for containing a food product as claimed in  claim 1 , wherein said sandwich packaging is formed of a low density polypropylene material.
