Claims..

The present invention relates to the art of wrapping andlabelling articles of merchandise, and more particularly to the application of labels, bands or other indicia bearing means to such 5 articles as are enclosed in a Wrapping material the overlapping edges of which are adapted t0 be sealed or welded together by the application of heat.

It is customary to wrap or otherwise enclose known articles of merchandise in a protective Wrapper, such, for example, as waxed paper. It is also customary to print identicaton and/or advertising indicia on such material prior to waxing the paper, or, alternatively, to place a relar"tively narrow strip or band of similar material,

bearing the desired indicia, on or about the wrapper after an article of merchandise has been enclosed therein. f

Recently, there has come into extensive use for 20 wrapping purposes, several kinds of transparent,

non-fibrous, cellulosic sheet materials. The moistureproof varieties of these materials are preferable to a waxed paper Wrapper by reason of their more complete transparency, higher moistureproofness, toughness and their ease of sealing upon the application of heat and pressure.

The printing of the moistureproof variety of this transparent, non-fibrous, cellulosic sheet material necessitates the use of inks containing 30 organic solvents. Therefore, in the process of printing with such inks, the material, as it leaves the printing press, is passed through a heating zone to dry the ink, both to prevent oisetting and to evaporate the ink solvent. In the roll form 35 in which this printed material commonly is supplied to the market, the odor of the residual printing ink solvent persists for long periods of time. Inasmuch as this odor is highly objectionable, particularly in wrappers for edibles, it becomes necessary to heat the material again, prior to its entry into the wrapping machine proper, in order further to dry out the printing ink and dispel its odor.

However, it is Well known that when this moisture-proofed, non-fibrous cellulosic sheet material is freely subjected to heat, as in the process of drying the printing ink, certain of its desirable characteristics are greatly impaired, if not enr tirely lost. For example, when heat is applied as above mentioned, the iiexibility, tensile strength,

moisture-proofness and heat-sealing characteristie of the material are4 adversely affected to a substantial extent.

Also, it is known that the cost of printing a Wider sheet of such aforesaid material is substantially greater than the cost of printing the same matter on a relatively narrower sheet. Further, as the indicia customarily occupies only a small portion of the sheet, there is no necessity oi' passing the entire web through the press and 5 subsequently heating the sheet in its entirety. As the material which has undergone printing and drying deteriorates more rapidly by reason therer of, it follows that va great waste and expense results when thus it has been rendered unsuited 10 for use.

It is the primary object of my invention to provide an improved wrapper comprising indicia in connection with transparent wrapping material of the type describedwhich will obviate the above noted disadvantages and objections.-

A further object of my invention is to provide indicia in association with this type of transparent wrapping material in a manner such that the expense of wrapping articles of merchandise therein Still another object of my invention is to provide an indicia bearing member adapted to be associated with a transparent wrapping material whereby the necessity of printing indicia directly on the wrapping material is eliminated.

' It is a further object of my invention to provide an indicia bearing member adapted to be associated with a transparent wrapping material whereby the indicia carried by said member will appear as if being carried by the wrapping material itself and whereby the indicia bearing member will lose its identity in that of the wrapper.

Another object of my invention is to so combine an indicia bearing member with the wrapping material'that the indicia bearing member is applied to an article of mechandise in an improved way during the wrapping operation.

And another object of my invention is to provide an improved combination of wrapper and 40 indicia bearing member of the type heretofore described which will be economical of manufacture, which may be easily and efciently applied to articles of merchandise and which, when once applied, cannot be easily separated without attracting attention thereto.

In accordance with my invention, I provide the desired indicia, such as identifying characters, advertising matter, etc., on a relatively narrow, transparent band after the manner shown, for example, in U. S. Patent No. 1,818,923. This transparent band is, preferably, of the same transparent material as is employed in wrapping the articles of merchandise, the wrapper, however, being entirely free from any printing or strength of the transparent wrapper with which it is associated. And, in order to insure the retention of the band and its wrapper in a predetermined relation, I apply a thin layer of transparent adhesive between the band and the wrapper, either in a continuous strip or at suitable intervals disposed longitudinally of said band, the adhesive serving, also, to retain the band suitably rolled up when rolled on a roller for vstorage prior to combining it with the wrapping roll.

The novel features of my invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and method of application. together with additional objects and advantages thereof,

will best 'be understood from the following description of several specific embodiments when read in connection with the accompanying drawings, in which y Figure 1 is a view, in perspective, showing a loaf of bread wrapped ina sheet of transparent wrapping material having associated therewith an indicia bearing band in accordance with my invention,-

Figure 2 is a. sectional view taken on the line 2-2 of Figure l,

Figure 3 is a bottom plan view showing one way in which the indicia bearing band may be applied to the wrapper sheet in accordance with my invention,

Figure 4 is a plan view of the transparent indicia bearing band with spots of adhesive applied to the upper side thereof, and

Figure 5 is a view in side elevation illustrating one manner in which the band and wrapper may be combined.

Figure 6 is a bottom plan view showing another way in which the indicia-bearing band may be applied to the wrapper sheet in accordance ,with my invention.

Figure 7 is a pian view of the transparent indicia-bearing band with the adhesive material applied to the upper side in the form'of short narrow lines.

Figure 8 is asectional view of a loaf of bread enclosed in a transparent, non-fibrous wrapping material with an indicia bearing band applied on the outside of the wrapper.

Referring to the drawings, wherein similar reference numerals indicate corresponding parts throughout, I have shown a loaf of bread 1, representative of any article of merchandise, completely enclosed in a transparent wrapper of nonfibrous cellulosic material 2 which has moisture proof qualities and the overlapping edge portions 3 of which can be sealed together by the application of heat and pressure thereto. Encircling the loaf 1 is a relatively narrow sheet or band of transparent material 4 having applied thereto, upon one surface thereof, as by printing, suitable indicia 5, such as advertising matter or the like. Preferably, the band 4 is of the same material as the wrapper 2 and is disposed between the loaf l and the wrapper 2 so that the band 4 will be practically invisible as an entity and so that its own identity will be substantially lost in that of' the wrapper. Preferably, also, the surface of the band 4 to which the indicia 5 has been applied is next adjacent, or in contact with, the inner surface of the wrapper 2. Thus. although the band 4 cannot, except on close scrutiny, be discerned apart from the wrapper 2, the indicia 5 thereon can readily be seen and read, and it appears to be applied directly on the wrapper itself.

The wrapping material 2 and the band 4 may be applied to the loaf 1 simultaneously, being fed to a suitable automatic wrapping machine (not shown) from the rolls 2a and 4a. respectively. In some cases, it may be desirable to combine the wrapper 2 and the band 4 at the paper mill in the manner shown in Figure 3 before supplying customers therewith. In other cases, however, it maybedesiredtorollthewrapperZandtheband 4 on separate rolls to be combined just prior to being fed to the wrapping machine, as illustrated in Figure 5. In either case, since the two are ultimately united into a unitary structure, it is essential that some means be provided for combining the two in a predetermined relation and for retaining them in this relation.

For this purpose, I provide, on'the band 4, an adhesive 6 which eifectively unites the band 4 with the-.wrapper 2. The adhesive should be transparent, preferably have the same index of refraction as the wrapper 2 and the band 4 to avoid contrast therewith, and may be applied to the band 4 in the form of a continuous strip 6 positioned adjacent and running parallel to the longitudinal edges of the band as shown in Figure 6, or, and preferably, in the form of a plurality of spots at spaced intervals. These spots may be applied in two sets, one along the longitudinalv edge 'I of the band, and the second set along the longitudinal edge 8 of the band. When the wrapper 2 and the band 4 with the adhesive spots 6 thereon are brought into contact in a predetermined relation and under pressure, as by passing through the 'rollers 10, l0, they are securely united together and their relative displacement thereafter is prevented. Thus, there is no danger of the band slipping and being improperly applied to the loaf 1 when, as in the wrapping and sealing operation, the wrapper and band are placed under tension.

'Ihe spots 6 may have any desired configuration, but I prefer to provide them in the form of small triangles, rhomboids, diamonds, circles, and/or short, narrow lines as illustrated in Figure 7. I also prefer to so locate them that the spots of one set on the band 4 will be in staggered relation with respect to the spots of the other set. While the adhesive spots 6 serve` in the case where the band 4 is rolled up by itself, to securely retain the band in convoluted form, it is essential that the rolled-up band be capable of free unwinding so that it can be freely supplied to the wrapping machine in association with the wrapper 2. If the proper adhesive is chosen and it is applied in the manner heretofore described, the staggered spots, terminating in points (or, at least, tapering oi!) in the direction in which the roll is unwound, permit free. unwinding thereof while still retaining suillcient tackiness to unite the band with the wrapper. For this purpose, the adhesive obviously must be of a permanently tacky, non-drying type.

From the foregoing description, it will be apparent that I have provided a method of applying indicia in connection with a package wrapped in transparent cellulosic material without subjecting the package to the disadvantages of the prior art. By applying the indicia on the band 4 instead of on the wrapper 2, the contaminating odors of the printing ink may be entirely removed without in any way aecting the moisture proof qualities of the wrapper, while the fact that the band 4 may have been weakened is quite immaterial.

Although I have shown and described certain specic embodiments of my invention, I am fully aware that various other modifications are possible. For example, it is possible to apply the band 4 on the outside of the package as illustrated in Figure 8 instead of within the wrapper 2, in which event the indicia and the adhesive are applied to the under surface thereof. My invention is not to be limited, therefore, except insofar as is necessitated by the prior art and by the spirit of the appended claims.
