Application April 27, 1931, Serial No. 533,305

8 Claims.

This invention relates to a wrapping material or film, rather than to a specific composition of matter, adapted to be used as an outer wrapping or confining medium for packages,parcels,cartons or the like, having attached thereto or incorporated as a part thereof a means for readily removing it from said packages when thus used.

One of the objects of my invention is to provide a means for readily removing tough wrapping material such as some of the synthetic cellulosic sheet membranes .(for example the material known as Cellophane) from packages. I find, in attempting to remove such wrapping material fromv packages that it is difiicult without the aid of a sharp instrument, knife or scissors. The result can be accomplished with a minimum of effort when a tape, string, ribbon or thread is attached to or incorporated in the wrapping membrane in such a manner that a free end can readily be gripped and pulled, thus tearing the membrane.

I find that a ribbon, tape or the like, including string, is satisfactory for the purpose in general. For certain purposes where decorative effect is desired a ribbon is preferred and it may be plain or fancy, narrow or wide. It is seldom that a ribbon over one half inch in width is desired; commonly the preferred ribbon is one having a width of about to inch. For very small packages such as candy bars, cigarettes and packages of similar size, a ribbon of even lesser width may be used.

Figure 1 shows a fiat sheet of a wrapping material with a ribbon integral therewith having a loose or free end.

Figure 2 is a plain view of a sheet of wrapping membrane havinga ribbon integral over a portion of its length with said membrane.

Figure 3 is a perspective view of a wrapped package showing the ribbon with free end in position to be pulled.

Figure 4 is a plan view of a membrane having grip-pieces attached thereto adapted to be used in tearing said membrane by the application of a pulling force. For certain kinds of packages this modification of my invention is preferred.

Figure 5 is a perspective view of a wrapped package showing different embodiments of my invention on one membrane.

In Figure 1, the membrane is shown at 1 with ribbon 2 having a loose or free end 3. The same numbers refer to similar parts in the other figures.

In Figure 2, the ribbon 2 is shown havinga end 3 and fixed portion 4, made of the same material as the membrane and is cemented thereto. Another finger'piece initially separate from membrane 1 is shown having free end 31 and attached portion 41. Ribbons 23 and 24 are also shown having free ends 33 and 34 respectively.

The ribbon shown in Figures 1, 2 and 3 need not be in a longitudinal position as shown but may be arranged in a diagonal position across the membrane or in any other position. The term ribbon is used to designate either string, thread or ribbon or finger-pieces as shown in Figure 4. The ribbon may be made of cloth or other materialof vegetable composition; it may comprise a strip of metal, or it may be a synthetic preparation including the same material of which the membrane is composed. tion is particularly adapted for the fingerpieces shown in Figure 4. To make these integral with membrane 1 it is only necessary to wet them with a solvent (membrane solvent) at the portions marked 4 and 41 and apply the wetted surface to the membrane with slight pressure; upon drying the membrane will tear when a pulling force is applied to said finger pieces provided they are stronger than the membrane. Thus it is desirable that the finger'pieces, when made of the same material as the membrane, be thicker than the membrane.

When cloth or similar ribbon is incorporated in the membrane it is preferably so incorporated at the time the membrane is made, however it can readily be made integral with said membrane by the use of a cementing material the simplest of which is comprised of a solution of some of the membrane material in a suitable solvent.

It is possible, and normally an inevitable result of incorporating a cloth, metal or similar ribbon in the membrane that the membrane material is thinner over the area of the ribbon and is therefore weaker. This is not the case when a ribbon is cemented to the surface of the membrane. Nevertheless a pull on a ribbon, cemented to or incased in a membrane having the strength The latter composiof the usual wrapping film, tears it adjacent the ribbon area.

Attention is called to the fact that my wrapping film is normally not perforated and therefore it may be used for hermitically sealing packages; this is not the case with a perforated wrapper.

The ribbon used is preferably initially separate from the remainder of the wrapper but at least a portion of it is made integral therewith or firmly attached thereto.

It is understood that the membrane or sheet wrapping material may be comprised of cellulose acetate, nitrate, or both, paper or other material that can readily be torn.

Having described my invention so that one skilled in the art may practice it, I claim:

1. A wrapping material adapted for use as an outer wrapper for packages, comprising, the combination of a flexible, imporous film of non-fibrous cellulosic material having a surface adapted to be the outer surface of said wrapper, and a long slender tearing member being substantial- 1y a ribbon having a portion of its surface midway its ends firmly cemented to said outer surface of said film, the ends of said ribbon being free, accessable for grasping and adapted to function both as a binding material and a means for rendering said wrapper readily removable.

2. A wrapping material adapted for use as an outer wrapper for packages, comprising, the combination of an imporous, flexible, non-fiibrous, cellulosic film having one surface adapted to be the outer surface of said wrapper, and a relatively long ribbon-like tearing member having a portion of one of its surfaces, a portion only of which is substantially integrally bonded to the said outer surface of said wrapper, the ends being free, accessible for grasping and adapted to be tied, the bonded ribbon being adapted to function both as a binding material and as a means for rendering said wrapper readily removable.

3. A wrapping material adapted for use as an outer wrapper for a package, comprising, the combination of a flexible sheet film of nonfibrous cellulosic material having a surface adapted to be the outer surface of said wrapper and an initially separate ribbon, a portion of the surface of said ribbon being integrally bonded to said outer surface, another portion of said ribbon being unattached and accesible for grasping, said ribbon having greater resistance to a tearing force than the adjacent film, being visible to the eye and adapted to receive a pulling force great enough to tear said film adjacent said attached portion, the whole of said ribbon comprising a grasping member confined within the perimeter of said film.

4. A wrapping material having one surface adapted to be the inner-side and one surface adapted to be the outer-side of a wrapper for packages, comprising, a flexible, non-laminated imporous film of substantially transparent cellulosic material having integrally bonded therewith on its aforesaid outer-side a portion of the surface of an initially separate ribbon of similar cellulosic material, the Whole of said ribbon being within the confines of the perimeter of said film, one portion of said ribbon being free and accessible for grasping.

5. A wrapping material adapted for use as an outer wrapper for a package, comprising, a nonfibrous, cellulosic film having a surface adapted to be the outer surface of said wrapper, and a relatively long slender ribbon-like tearing member integrally bonded throughout a portion of its surface to the said outer surface with such intensity as to cause rupture of said film when a pulling force is applied to said member, said member having a free portion accessible for grasping.

6, A wrapping material adapted for use as an outer wrapper for a package, comprising, a nonfibrous, cellulosic film having a surface adapted to be the outer surface of said wrapper, and a relatively long slender ribbon-like tearing member of similar material integrally bonded throughout a ribbon-like portion of this surface'to the said outer surface with such intensity as to cause rupture of said film when a pulling force is applied to said member, said member having a free portion accessible for grasping.

7. A wrapping material adapted for use as an outer wrapper for a package, comprising, a flexible, nonfibrous, cellulosic film having a surface adapted to be the outer surface of said wrapper, and means adjacent said outer surface for tearing said film, said means comprising a ribbonlike grasping member a ribbon-like portion of which is substantially continuous and integral with the material of said film on said outer surface, another portion of said member being free and accessible for grasping.

8. A wrapping material adapted for use as an outer wrapper for a package, comprising a flexible, nonfibrous, cellulosic film having a surface adapted to be the outer surface of said wrapper, and a substantially ribbon-like tearing member integrally bonded throughout a portion of its length to said outer surface with such intensity as to cause rupture of said film when a pulling force is applied to said member, said member having a free portion accessible for grasping.
