7 Claims.

This invention relates in general to certain new and useful improvements in composite paper rolls.

For a number of commercial uses, and, particularly for use in frozen food lockers, it has become standard practice to employ a plurality of separate sheets of wrapping material for achieving the several separate functional results inherent therein. For example, in frozen food lockers, when meat and poultry are being wrapped for storage, it is desirable to enclose the meat or fowl in a strong durable wrapper, and, at the same time, to enclose the meat or fowl in a relatively moisture-proof wrapper. Heavy paper, of course, is a strong, tough, and durable protective wrapper, but is not moisture-proof. Cellophane, Pliofilm, and other synthetic wrapping materials, on the other hand, are moisture-proof, but have relatively poor physical strength for protective purposes. Therefore, the frozen food lockers commonly employ separate sheets of heavy durable wrapping paper and lightweight moisture-proof synthetic film for achieving the desired combina tion of protective and moisture-proof characteristics.

Obviously, however, it is wasteful, uneconomical, time-consuming, and expensive to have the heavy wrapping paper in sheets or rolls and the synthetic film in separate sheets, thereby making it necessary for the locker employee or attendant, upon wrapping the food, to lay down a sheet of heavy wrapping paper, superimpose upon it a sheet of synthetic film, and then wrap the food in the thusly formed composite sheet. In addition, the package formed in this manner is not entirely satisfactory since the overlapping edges of the synthetic film are not superimposed upon each other, but are separated from each other by the intervening plies of non-moistureproof paper, and the resulting package is not as fully moisture-proof as it should be.

It is, therefore, the primary object of the present invention to provide a composite roll of wrapping material which is simple and economical and makes conveniently available a supply of composite wrapping sheets which combine both the structural strength of paper and the moistureproof characteristics of synthetic film.

It is a further object of the present invention to provide a composite roll of wrapping material uniquely arranged for severance from the roll of a sheet of any desired length, which sheet, furthermore, is conveniently set up for most efficient manual manipulation during the course of the wrapping procedure.

And with the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts presently described and pointed out in the claims.

In the accompanying drawing:

Figure 1 is a perspective view of a preferred form of roll of composite wrapping material constructed in accordance with and embodying the resent invention;

Figure 2 is a transverse sectional view taken along line 22 of Figure 1;

Figure 3 is a perspective view of a modified form of roll of composite wrapping material constructed in accordance with and embodying the present invention;

Figure 4 is a transverse sectional view taken along line 44 of Figure 3;

Fi ure 5 is a perspective view of a further modified form of roll of composite wrapping material constructed in accordance with and embodying the present invention; and

Figure 6 is a transverse sectional view taken along line 66 of Figure 5.

Referring now in more detail, and by reference characters to the drawing, which illustrates a preferred embodiment of my invention, A designates a preferred form of roll of composite wrapping material consisting of a double ply arrangement composed of an outer web or sheet of heavy paper 1 having an upwardly presented thin layer or coating of paraffin 2, and an inner web or sheet of preferably transparent synthetic film 3, such as moisture-proof Cellophane, Pliofilm, or the like. The transverse width of the webs or sheets l and 3 are substantially the same, but, in winding, the two webs are laterally offset with respect to each other so that the sheet I projects outwardly beneath the web or sheet 3, as at a, and, contrariwise, on the othe rside, the sheet or web 3 projects marginally outwardly over and above the edge or margin of the sheet or web I, as at b.

Thereupon, when the roll A is mounted in a conventional paper roll hanger (not shown) and is pulled out beneath the cutter knife thereof, a rectangular sheet of any suitable length may be torn ofi. Depending upon the particular requirements and desires of the butcher or other frozen food locker employee, the severed sheet may be laid upon a wrapping table with the socalled paper side down, whereupon the meat or other food may be placed upon the upwardly presented moisture-proof synthetic sheet and wrapped first therein. Because of the relative placement of the two sheets of material, one readily grippable edge of the synthetic film will be presented freely outwardly so that it may be grasped and the sheet pulled up around the article of food being wrapped, thereby obviating the annoying and time-consuming operation of trying to separate two closely superimposed and marginally aligned sheets. The first wrapping of moisture-proof material will, of course, be overlapped and sealed upon itself, thereby taking advantage of the tendency of the surfaces of moisture-proof synthetic films to adhere autoadhesively to each other, and thereby creating a comparatively well-sealed initial wrapping. Thereupon, the remaining ply of heavy parafiincoated paper stock may be wrapped entirely around the first package preferably with the overlapping seams and end seals running in opposite directions, thereby providing a protective and seal-supplementing outer wrapping. It should also be noted in this connection that the severed rectangular sheet of composite wrapping material may, with equal facility, whenever the particular need requires, be laid film side down upon a wrapping counter so that the material to be wrapped may first be wrapped in paper and then secondarily wrapped in the moisture-proof synthetic film, and in such instance the outwardly projecting margin of the paper, as at a, will again provide a convenient overhanging portion which can readily be grasped to facilitate manual manipulation of the paper during wrapping operations.

If desired, a modified form of roll A of composite wrapping material may be provided comprising an outer web of heavy paper stock 4 having an inner film or coating 5 of paraffin or similar wax-like material, and a web or sheet of moisture-proof synthetic film 6, the latter being somewhat wider than the paper web 4, and being in registration therewith along one lateral margin, and projecting outwardly thereof along the other margin, as at c.

When a rectangular sheet is severed from the roll A and laid paper side down upon the wrappin table, an outwardly extending manipulating margin will be provided by the overhanging edge of the moisture-proof synthetic material, as at c.

A further modified form of roll A" of composite wrapping material may be provided, as shown in Figures 5 and 6, comprising an outer web of heavy paper 7 having an inner film or coating 8 of paraffin, or other wax-like material, and an inner web of moisture-proof synthetic material 9, the webs 1 and 9 being of substantially the same transverse width and being marginally aligned along both lateral margins. The web 1 is provided at spaced intervals along one lateral margin with preferably U-shaped indentations or so-called finger-cuts l0, and the web 9 is similarly provided at spaced intervals with preferably U-shaped indentations or so-called finger-cuts ll, thereby facilitating the manipulation of the composite sheet of wrapping mate- 4 rial when severed from the roll A" during actual use.

It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the composite paper roll may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
