[57] ABSTRACT [52] U.S. Cl. 229/68, 229/75 [51] Int. Cl B65d 27/00 The inv nti n relates to a lightweight envelope having [58] Field of Search 229/68, 75 corrugated in rnal ces which serve to rigidify the envelope construction and also serve to protect an article [56] References Cited or articles placed in the envelope from damage.
UNITED STATES PATENTS 3,501,084 3/1970 Harrison 229/68 R 3 Claims, 2 Drawing Figures IMPROVED ENVELOPE This invention has been devised to provide a comparatively light weight envelope which is of substantially rigid formation. It is particularly useful for transport and retention of sheets, documents and other matter; e.g., music records and the like which require to be protected against distorting forces.
Two forms of the invention are illustrated in the annexed drawings wherein;
FIG. 1 is a perspective-view of a first form of the envelope, and
FIG. 2 is a fragmentary perspective view of a second form.
In both forms the envelope is made of a single face corrugated sheet 3, of either paper, reinforced cloth or thermoplastic material, with or without a waterproof coating which is creased and folded transversely across the corrugations to provide a front and back and a sealing flap 4 and the side edges 5 are secured with an adhesive.
In the form shown in FIG. 1 the corrugated sheet 3 has two folds 6 and 7 therein fonned by creasing the corrugations. One fold 6 makes the back and front 8 and 9 respectively of the envelope and the other fold makes the sealing flap 4. The side edges 5 are secured together as stated above.
FIG. 2 illustrates the second form where the envelope is required to accommodate material of a substantial thickness. Two folds l0 and 11 are formed in the sheet by creasing the corrugations to form the bottom 6A of the envelope, the length of flap 4A is extended to the this has been allowed for in increased widths of the envelope. The edges 5A are secured together in the same manner.
The manufacture of the envelope, including the cutting, creasing and folding and glueing, is achieved by simple machine operations. I
I claim:
1. An envelope of substantially rigid formation comprising a single face corrugated sheet folded transversely across the corrugations at two longitudinallyspaced locations to provide a front and a back and a sealing flap, the corrugations extending from one end of the sheet to the other and forming the internal faces of the envelope and the sealing flap, the side edges of said sheet'being straight and disposed parallel to the corrugations throughout the entire length of said sheet and being secured with an adhesive layer extending across at least two corrugations and filling the valley therebetween.
2. An envelope as claimed in claim 1 wherein the folds are formed by creasing the corrugations.
3. An envelope as claimed in claim 1 wherein two folds are formed at one location to provide a bottom with spaced apart sides and two corresponding folds are formed at the other location to provide a complementary sealing flap to provide a top with spaced-apart sides.

Claims (3)
1. An envelope of substantially rigid formation comprising a single face corrugated sheet folded transversely across the corrugations at two longitudinally-spaced locations to provide a front and a back and a sealing flap, the corrugations extending from one end of the sheet to the other and forming the internal faces of the envelope and the sealing flap, the side edges of said sheet being straight and disposed parallel to the corrugations throughout the entire length of said sheet and being secured with an adhesive layer extending across at least two corrugations and filling the valley therebetween.
2. An envelope as claimed in claim 1 wherein the folds are formed by creasing the corrugations.
3. An envelope as claimed in claim 1 wherein two folds are formed at one location to provide a bottom with spaced apart sides and two corresponding folds are formed at the other location to provide a complementary sealing flap to provide a top with spaced-apart sides.
