Serial I0. 282,509.

The present invention relates to the art of wra ping articles. It has for its object the prodhction of a novel tygi-of package in gvhich printed labels are a ed to an underying wrapper by which a is, for the first time, possible to form such a package. a

It has been common in certain lines of merchandise to wrap the articles in a rinted paw per, and to place on the'ends of t e package,

whereby reason of the folds the (printed wraper is not a good medium for 'splaying the 'uesired trade-marks or information, a printed label glued in place across the end folds.

, s With merchandise subject to deterioration unless protected from changes in moisture content, it has also been common to surround the articles with'a wax paper covering stuck together by heat sealing. Over the body of coveringis sufii ciently trans arent to dis lay the printing underneath, at at the en ofthe package the necessary folds, resulting in creases and in additional thickness, have destroyed the transparency to such a degree that end labels were made practically illegible when applied to the package underneath.

Previous attempts to apply end labels over the wax paper have not been successful, as so ordinal methods of attachment fail to produce a esion. The use of wax as an adhesive renders the application easy, but the adhesion is not permanent and a rohibitive proportion of the labels peel -o Glue or paste applied in the ordinary manner will not stick to wax paper and, therefore, have not been used. I havefound that by a special procedure it is possible to employ the usual adhesives, which produces. permanent union with the underlying paper.

Referring to the drawings;

Fig. 1 is a perspective view of a package with a wax paper wrapping thereon; I

Fig. 2 is a plan view of the package illustrating the method of sealing the ends of the wax paper and preparing it for the application of an end label;

Figs. 3 and 4 are plan views illustrating the manner ofapplication of the adhesive coated label; and

of waxed paper, and a process Fig. 5 is a plan view illustrating a modirocedure.

e package 10 is shown in Fig. 1 as covered with a layer of wax paper having folds 11, 12 at the ends. The particular manner of folding is immaterial. In order to seal the wax out of the way and bring the adhesive into contact with the underl paper. In Figs. 3 and 4 I have shown the 1a 1, with the side which is to be in contact with the package coated with adhesive, supported on a rocker 16 serving to press the label by rolling contact against the'package end. Various mechanisms may be used for this purpose, as for example the label a plying device shown in my prior Patent o. 1,575,7 23, granted Marc 9,1926. l

Any good adhesive ma be used upon the label, as the primary mode in which my in vention operates appears to be the pressing of the wax out of the way so that the adhesive may make direct contact with the underlylng paper. It is, however, referable to use an adhesive such as Cereso which has inherent adhesion for wax as well as for paper. In either case, however, I believe the main bond to be between the adhesive and paper.

As a further means of assisting the rolling away of the wax, I have found that moistening the wax, eitherbefore or after heating, with a solvent such as carbon tetrachloride will further increase adhesion if this is found necessary. In Fig. 5 I have shown a wick 18 mounted in a container 19 in position to apply the solvent after the package has passed the heat sealer 13, although the relative What I claim' is:

1. A method olfizpplymg' a label to a wtaltl'x r w comprises softenmp e m an adhesive coated abel the softened area.

2. A method of applying a label to a wax paper packa whic comprises fusin the wax and r0 ing an adhesive-coated abel 'nst the area of fusion. 3. A method of applying a label to a wax 10 paper packa e which comprises fusing the wax and r0 up; an adhesive coated label against the area of fusion with sufiicient pressure to force away the fused wax and bring the adhesive in direct contact with the under- 15 y g NP- 4. A method of ap lying a label to a wax paper package whic comprises subjecting an area of the wax to fusion and the action of a solvent, and rolling an adhesive coated m label against the softened area with sufiicient ressure to force away the softened wax and ring the adhesive in direct contact with the underlying paper.

5. A method of a plying a label to a wax 25 paper package whic comprises heating the overl 'ng folds of the wax paper to seal them toget er, and while the wax is still soft from this heat rolling anadhesive-coated label against the heated area with suflicient presa sure to force away the fused wax and bring the adhesive in direct contact with the underlying paper..
