Benefits of technology

[0013] 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. The width of the ridge can be adjusted according to the thickness of the sandwich by having the plurality of openings or projections, thereby reducing the spaces between the sandwich protector and the sandwich, and further preventing the incidents of being deformed under compression or spilling out of fillings.
[0014] The surface of the top cover, the bottom cover or the ridge has a plurality of perforations for ventilation, thereby avoiding water vapours from condensing in the sandwich affecting the quality of the sandwich.
[0015] The surface of the top cover, the bottom cover or the ridge has a plurality of hollows or projections, and the bottom surface

Problems solved by technology

However, this type of sandwich boxes will easily deform after being compressed.
If a sandwich has too much fillings or is too large, it can hardly be placed in the box.
It not only wastes the space, but also allows the fillings to spill out in the box which causes inconvenience in taking the sandwich.
Although this solves the problems of the deformed sandwiches and of the non-reusable sandwich boxes, there are still the problems of fixed shape and storage

Example

[0027]FIGS. 3 and 4 illustrate the second embodiment of the present invention. Its structure is substantially similar to that of the first embodiment. It also comprises a folder-shaped container 1, a top cover 2, a bottom cover 3 and a ridge 4 joining the two covers. However, in this embodiment, the top cover 2, the bottom cover 3 and the ridge 4 form one piece. The ridge 4 is connected securely to the connecting lines of the top cover 2 and the bottom cover 3 and the folding lines 6 thereon are pressed lines for easy folding. Although users cannot use this embodiment to flexibly adjust the height of the ridge 4 according to the thickness of the sandwich, this embodiment is of a simple structure and a lower production cost, which is suitable for the manufacturers to package a large volume of sandwiches of the same size.

Example

[0028]FIGS. 5 and 6 shows the third embodiment of the present invention. Its structure is substantially similar to that of the first embodiment. It also comprises a folder-shaped container 1, a top cover 2, a bottom cover 3 and a ridge 4 joining the two covers. However, in this embodiment, the top cover 2, bottom cover 3 and the ridge 4 are formed separately. On the ridge 4, there are five folding lines 5, which are pressed lines for easy folding. The ridge 4 is removably connected by a connecting mechanism in between the top cover 2 and the bottom cover 3. The connecting structure comprises six substantially parallel rows of openings 7 on the ridge 4, with each row having two openings 7, and two projections 8 corresponding to and removably connecting to the openings 7 on any row of the ridge 4 on the edges of the top cover 2 and the bottom cover 3. In other embodiments, the connecting structure may also comprise two openings 7 on the two edges of the ridge 4, and two projections 8 ...

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.

Description

[0001] The present invention relates to a sandwich protector and more particularly pertains to a foldable sandwich protector. BACKGROUND OF THE INVENTION [0002] The sandwich containers available in the marketplace can be broadly divided into two types, namely the boxes and the bags. Some sandwich boxes are made of soft transparent plastic in triangular shape with a cover on one side that can be opened and closed. However, this type of sandwich boxes will easily deform after being compressed. Besides, they are of a fixed dimension. If a sandwich has too much fillings or is too large, it can hardly be placed in the box. If the sandwich has little fillings or is smaller, there will be space in the box. It not only wastes the space, but also allows the fillings to spill out in the box which causes inconvenience in taking the sandwich. Some other sandwich boxes are made of hard plastic. Although this solves the problems of the deformed sandwiches and of the non-reusable sandwich boxes, t...
