Sandwich protector

Abstract

The present invention relates to a sandwich protector comprising a folder-shaped container which is formed by a top cover, a bottom cover and a ridge joining the top cover and the bottom cover; and the ridge has two or more substantially parallel folding lines. The present invention is of simple structure, convenient for use and storage, reusable and environmental friendly. It can prevent the sandwich from being deformed under compression, and it can be adjusted according to the width of the sandwich.

1 . A sandwich protector comprising a folder-shaped container which is formed by a top cover, a bottom cover and a ridge joining the top cover and the bottom cover; and the ridge has two or more substantially parallel folding lines.  
   
   
       2 . The sandwich protector as in  claim 1 , wherein the width of the top cover matches the height and measures 10 cm to 25 cm, and the width and the height of the bottom cover match those of the top cover and each measures 10 cm to 25 cm.  
   
   
       3 . The sandwich protector as in  claim 1 , wherein the width of the ridge measures 2 cm to 12 cm; its height matches that of the top cover and that of the bottom cover and measures 10 cm to 25 cm.  
   
   
       4 . The sandwich protector as in  claim 1 , wherein the top cover, the bottom cover and the ridge form one piece; the ridge is connected securely to the connecting lines of the top cover and the bottom cover and the folding lines thereon are pressed lines.  
   
   
       5 . The sandwich protector as in  claim 1 , wherein the ridge form one piece with either the top cover or the bottom cover; the ridge is connected securely to the connecting lines of the top cover or the bottom cover and the folding lines thereon are pressed lines, and the ridge is removably connected by a connecting mechanism to the bottom cover or the top cover to which it is not connected securely.  
   
   
       6 . The sandwich protector as in  claim 1 , wherein the top cover, bottom cover and the ridge are formed separately; the folding lines on the ridge are pressed lines; the ridge is removably connected by a connecting mechanism in between the top cover and the bottom cover.  
   
   
       7 . The sandwich protector as in  claim 5  or  6 , wherein the connecting mechanism comprises two or more openings or projections on the edge of the ridge, and two or more projections corresponding to and removably connecting to the openings of the ridge, or two or more openings corresponding to and removably connecting to the projections of the ridge, on the edge of the top cover or the bottom cover.  
   
   
       8 . The sandwich protector as in  claim 5  or  6 , wherein the connecting structure comprises two or more substantially parallel rows of openings or projections on the ridge, with each row having two or more openings or projections, and two or more projections corresponding to and removably connecting to the openings on any row of the ridge, or two or more openings corresponding to and removably connecting to the projections on any row of the ridge, on the edge of the top cover or the bottom cover.  
   
   
       9 . The sandwich protector as in  claim 1 , wherein the surface of the top cover, the bottom cover or the ridge has a plurality of hollows or projections, and the bottom surface of which has a plurality of hollows which correspond to the projections on surface, or a plurality of projections which correspond to the hollows on surface; the folder-shaped container can be flattened and a plurality of them can be placed together in layers by connecting the hollows or projections on the bottom surface of the top cover, the bottom cover or the ridge of a folder-shaped container to the corresponding projections or hollows on the surface of the top cover, the bottom cover or the ridge of another folder-shaped container immediately underneath, thereby removably connecting one folder-shaped container with another one underneath.
