HERMAN L. GREVE, OF BROOKLYN, NEW YORK, ASSIGNOR TO THE INTERNATIONAL MAILING TUBE 82; WRAPPER COMPANY, OF BROOKLYN, NEW YORK.

i 1 l MAILING WRAPPER,

To all whom it may concern:

.Be it known that HERMAN L. Gnnvn, a citizen of the United States, and a resident of New York city, in the borough of Brooklyn, in the county of Kings and State of New York, has invented certain new and useful Improvements in Mailing Wrappers, of which the following is a specification.

My invention relates to wrappers for merchandise and especially to mailing wrappers therefor.

The object of my invention is to provide a cylindrical shaped mailing wrapper comprising an inner sheet of rather stiff heavy material and an outer sheet of comparatively thin and flexible material held together, the inner sheet being permanently pressed by suitable means into a curved form to permit the wrapper being folded manually.

Referring to the drawings which form a part of this specification,

Figure 1 is a front view of a wrapper embodying my invention, shown partly in section.

Figure 2 is a similar View illustrating a modification in construction.

Figure 3 is an end view of the construction illustrated in Figure 1.

Figure 4 is a view of the wrapper before 30 the ends of the outer sheet are tucked within the cylinder to close the wrapper.

I prefer to make the wrapper of paper stock, the inner sheet being of a thickness and stifiness too great to be properly rolled into cylindrical form by the hands only.

A, indicates the inner sheet and B the outer one.

In Figure 1, I have shown the two sheets held together over the entire adjacent contacting surfaces between sheets A and B, the gummed surface of sheet A being indicated by C. The two sheets are first cemented together in their flat condition and the gum allowed to dry or nearly dry, and in the drying process the inner sheet tends to bend in the opposite direction to that required to provide the wrapper with the thick sheet inside, and therefore it is necessary to place the sheets between rollers and roll the same into the desired form, the fibres of the cardboard being pressed and stretched until'it retains its proper form, substantially as illustrated in Figure 3.

In Figure 2 the lower ends only of the two sheets are shown cemented together as Application filed March 18, 1922. Serial No. 544,819.

illustrated at D. The sheet B is preferably made longer and of greater width than sheet A, and its ends BB' respectively, are tucked into the open ends of the wrapper to close the package. By reason of the heavy inner sheet being formed as illustrated, it is comparatively easy to roll it into the completed cylindrical form illustrated in Figure 4 whereas without being so formed it would be very difficult to bind the inner sheet and from a practical commercial standpoint, entirely impractical.

By constructing a wrapper in this Way a much stronger casing is provided of a two sheet construction than heretofore, in so far as I am aware.

Having thus described my invention I claim as new:

1. A mailing wrapper comprising an inner sheet of stiff material having non-corrugated surfaces, and a relatively thin outer sheet of greater area attached thereto and adapted to inclose the inner sheet, said inner sheet being molded into a. permanently curved shape to form a restricted opening and facilitate its being formed into cylindrical shape, and thereafterbeing incapable of assuming a flattened out position by itself.

2. A mailing wrapper comprising an inner sheet of stiff material having non-corrugated surfaces, and a relatively thin outer sheet of greater area attached thereto at its lower end and adapted to inclose the inner sheet, said inner sheet being molded into a permanently curved shape to form a restricted opening and to facilitate its being formed into cylindrical shape and thereafter being incapable of assuming a flattened out position by itself.

3. A mailing wrapper comprising an inner sheet of stiff material having non-corrugated surfaces, and a relatively thin outer sheet of greater area attached thereto at its lower end only and adapted to inclose the inner sheet, said inner sheet being moulded into a permanently curved shape to form a restricted opening and to facilitate its being formed into cylindrlcal shape, and thereafter being incapable of assuming a flattened out position by itself.

4:. A mailing wrapper comprising an inner sheet of stiff material having non-scored surfaces, and a relatively thin outer sheet of greater area attached thereto and adapted to inclose the, inner sheet, said inner sheet being moulded into a permanently curved shape to form a restricted opening and to facilitate its being formed into cylindrical shape and thereafter being incapable of assuming a flattened out position by itself.

5. A mailing Wrapper comprising a fiexible outer sheet and a smaller stiff inner sheet normally curved in form to facilitate rolling the wrapper into cylindrical shape secured to said outer sheet, the longitudmal edges of the said inner sheet forming a restricted opening to enable quick and easy insertion of the article to be Wrapped.

6. A mailing Wrapper comprising a flexible outer sheet and a smaller stiff inner sheet normally curved in form to facilitate rolling the Wrapper into cylindrical shape attached to the outer sheet at the lower edges, the longitudinal edges of the said inner sheet forming a restricted opening to enable quick and easy insertion of the article to be Wrapped.

Signed at Brooklyn, New York, in the county of Kings and State of New York this 15th day of March A. D. 1922.

HERMAN L. GREVE.
