4 Claims.

This invention relates to a carton and method of making the same, and more specifically to a carton with a tight-sealed outer wrapping and method of making the same.

In general, it is an object of the invention to provide a device of the character described which will efliciently perform the purpose for which it is intended, which is slinple and economical of construction, which can be conveniently and safely handled, and which can be readily manufactured and assembled, and a method for making the same.

Another object of the invention is to provide a carton having a smooth, waxed or otherwise coated, moisture-proof wrapping which is adhesively secured to the carton.

Another object is to provide a method for securing upon itself a smooth, waxed, outer wrapping for a carton and for securing such a wrapping to 20 the carton.-

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordinglycomprises the several steps and the relation and order of one or 25 more of such steps with respect-to each of the others, and the article possessing the features, properties, and the relation of elements, which are exemplified in the following detailed disclosure, and the scope of the application of which will be indicated m the clclllls.

For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawing, in

which: e

Fig. 1 is a view in perspective with' a portion cut away of a device embodying one form of the invention.

o In the drawing, Ill denotes a carton of any convenient sizeand shape. Surrounding the carton I is a wrapping of any desired material, preferably a moisture-proof material, such as waxed paper or moisture-proofed regenerated cellulosic sheet, material, such for example as Cellophan This smooth-surfaced-material, which will hereinafter be referred to as material having a wax-like surface, is securedto itself in any interlocking fashion,-for example, by overlapping edges. For this purpose an adhesive may be used, preferably containing rubber, which may be in the form of latex or of crepe-rubber particles in suspension.

The portions of the wrappin which are to be intersecln'ed may be prepared with theadheslve, heated to permit the adhesive to penetrate the 1934, Serial No. 715,864 (cl. 229-87) coating on the wrapping, and allowed to dry. Thereafter, those parts may be joined by pressure about the container. Similarly, a. portion of the container may have the adhesive applied thereto and a portion of the wrapping which is to be in registry with the said portion of the container may be also prepared in the same fashion.

When the container and the wrapping are brought together under pressure they will remain attached to each other.

If it is desired, in the case where the adhesive between the layers of the wrapping has not been permitted to dry before the wrapping is folded upon itself, such pressure may be used during the intersecuring of the wrapper upon itself that a portion of the adhesive is caused to be squeezed out from between' the overlying portions of the wrapping and to become fixed between the wrapping and the container, whereby they are permanently joined. When this is done heat should preferably be applied to that portion of the wrapping overlying the adhesive, so that the adhesive may penetrate the wax or other coating on the wrapping and efiect a tight bond therewith.

It will be apparent that an exceedingly simple and direct methodv of attaching a smooth, coated, outer'wrapping to an inner container has been described above, which results-in a particularly desirable carton. The outer wrapping may be broken open and the carton itself entered without the danger which has heretofore been present with smooth, moisture-proof wrappings that the wrapping immediately upon its breakage in any part would slide oflf from the inner carton. The present device permits the inner carton to be reclosed and the outer wrapping to be refolded so as to continue to give a relatively large amount of protection against moisture and the like, even after the carton has been once opened. Furthermore, the outer wrapping may, where the invention here disclosed is employed, be tightly sealed so as to (give a truly moisture-vapor-dust-p'roof wrapping to the container. The seal obtained may be even'stronger than the wrapping itself.

Since certain changes in carrying out the above process and certain modifications in the article which embody the invention maybe made without departing from its scope, it is intended that all matter contained in the above description or shown in the accomp ny ng drawing shall be interpreted as illustrative, and not in a limiting sense.

' It is also to be understood that the following claims are intended to cover all of the generic I and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language. might be said to fall therebetween.

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

1. A method of packaging. comprising enclosing material within a container, encasing said container with a coated, moisture-proof wrapper, sealing said wrapper on itself with an adhesive containing rubber by heating said wrapper to permit the said adhesive to penetrate the coating on said wrapper, and intersecuring said wrapper and said container by causing a certain quantity of adhesive to be expelled from the folds of said wrapper during the sealing of the latter and to become fixed between said wrapper and said con tainel'.

2. A method of packaging, comprising enclosing material within a container, encasing said container with a coated, moisture-proof wrapper, sealing said wrapper on itself with an adhesive containing rubber by heating said wrapper to permit the said adhesive to penetrate the coating on said wrapper, and intersecuring said wrapper and said container by causing a certain quantity of adhesive to be expelled from the foldsof said wrapper dining-the sealing of the latter and to become fixed between said wrapper and said container, at a point such that when said wrapper and said container are opened said point will not be disturbed whereby said smooth wrapper may be retained fixed to said container.

3. In a package of the class described, a container, a wrapper completely enclosing said container and provided on at least one facethereoi with a wax-like, moisture-proof material, all overlapping edges of said wrapper being secured together by a moisture resistant adhesive containing rubber, said wrapper also being secured to said container along at least one of said overlapping edges whereby to form a package whose contents are protected throughout against moisture.

4. In a package of the class described, a container, a moisture-proof wrapper therefor having a wax-like, moisture-proof coating completely enclosing said container, and having all of its overlapping edges secured together by a moistureproof adhesive containing rubber, said wrapper also being secured to said container along at least ,one of its overlapping edges by the same adhesive used invsecuring said edges together whereby to form a package whose contents are protected throughout against moisture.
