13 Claims. (Cl. 229-51) The present invention has for an object, the makingof a novel package which is impervious to moisture and which is-provided with means for readily opening thesame so-that one can get at the contents thereof.

Another object of this invention is to provide a very simple method for making a wrapper of the class described. 7

A still furtherfobject ofthisinvention is to provide a double wrapper for an article or group of articles with means for readily 1 opening both wrappers by a single niovenientlof the opening means, the opening meansbeingi associated-with the package itself.

Another object of this invention is to provide means for opening a package which is sealed, at one end only to permit access to the contents of the package so that portions of the contents may be removed without removing other portions thereof or destroying the wrapper about the portions which are not removed.

Other objects of this invention will appear hereinafter as the description thereof proceeds, the novel features, arrangements, and combinations being clearly set forth in the appended claims:

In the drawing:

Fig. 1 is an isometric view showing the first step in the formation of a package;

Figs. 2 and 3 are similar views of subsequent steps in the formation of the package;

Figs. 4 and 5 are end elevations of the package in a further stage of formation;

Fig. 6 is an end view of the package with only the first wrapper in place and fully completed;

Fig. 7 is a side elevational view of the package shown in Fig. 6 with an additional wrapper about the same shown in cross-section; and

Fig. 8 is a perspective view of the package with parts thereof broken away for the sake of clearness.

The package constructed according to this invention comprises a group of articles wrapped in waxed paper and heat-sealed, and an additional layer of foil about the first layer with means for opening the wrapper at one end of the package so as to make the contenisthereof readily accessible. In Fig. 1 I have illustrated a sheet of waxed paper at It] with a group of articles II which in the present instance are cylindrlcally shaped pieces of candy of a rather well known type. Such candy must be protected from moisture in order to preserve the candy in the desired state. The formation of the package is illustrated rather schematically and particular apparatus for form- 5 ing the package is not disclosed herein, but the essential steps will be described.

on the surface of the waxed sheet In upon which the candy I I is placed, I lay a ribbon-like band I2 of fabric or any suitable means which will not 10 break under th. required tension to open the package and preferably, although not necessarily, apply heat to cause the band to adhere to the surface of the sheet I0 at about the angle illustrated in Fig. 1 with respect to one edge of the wrapper. 15 I then take the end I3 of the wrapper and wrap this about the articles together with the band I2 by bringing the and I3 over the articles and then rolling the articles and sheet until the entire sheet is wrapped about the cylindrical surface pre- 20 sented by the group of articles I I as is clearly illustrated in Fig. 2. This leaves cylindrical portions of the wrapper projecting beyond the ends of the groups of articles and I next proceed to fold these projecting cylindrical portions. Since the band 25 I2 projects beyond one edge I I of the sheet l0 when laid thereon, it is obvious that a portion of this band I5 will protrude beyond the cylindrical portion of the wrapper which projects beyond the end of the group of articles so that if the cylin- 3o drical portion is folded, over the end-most one of the articles to seal the package, the and I5 of the band will protrude therefrom making the same accessible to one desiring to open the package.

The next operation is to fold the cylindrical 35 portion inwardly against the end-most article adjacent that portion. This is done by successive steps. The first step is illustrated in Fig. 3 and comprises moving a portion I6 inwardly against the end-most article I1, the band I! being carried) along therewith. The next step is .to fold the portions, I8 adjacent the portion I6 against the end of the article I! as illustrated in Fig. 4. I next fold the portion I9 diametrically opposed to portion I6 over the end of the article and finally 45 fold the portions 20 intermediate the portions l9 and I8 against the article to completely fold the projecting portion of the wrapper against the end of the article II with the end I5 of the band extending in a position such as that illustrated in H0 Fig. 6.

As can be readily seen in Fig. 3, portions of the band I5 lie between adjacent layers of the waxed sheet III which extends beyond the group of articles and therefore when the successive folds IS, an

l8, l9, and 20' are made, the hand I! is so arranged that upon exerting a pull on the projecting end l5 thereof, the folds are caused to unfold. The folds are heat-sealed together either as they are formed or after all of the folds have been formed. The heating of the folds causes the wax of the paper to run together and hold the folds accordingly together when the heating means is removed and the wax has had a chance to solidify.

I next take the package illustrated in Fig. 6 and wrap the same in an additional layer of wrapping material such as tin foil in substantially the same manner with the result that projecting end l5 of the band in Fig. 6 which extends beyond the side of the package in that figure is moved inwardly due to the folding operation to such a position that it does not project beyond the sides of the article. This is accomplished by first moving the portion 2| of the foil wrapper 22 toward the protruding end I 5 of the band and then against the end of the package, with the last or a subsequent fold 23 moved against the projecting end l5 of the band to cause the band to assume the shape illustrated clearly in Fig. 7 with, a portion thereof still projecting in an accessible position outside of the package but not beyond the sides of the package as it does in Fig. 6.

The completed package is shown in Fig. 8 with the projecting end l5 of the band lying flatly against the end of the package but not beyond the sides of the package. This enables the package to be more readily handled and does not detract from the neat appearance thereof. Also in packages of this nature, it is common to apply a label preferably about the article and it is easier to do this if the projecting end I5 does not extend beyond the sides of the article but lies wholly within the outer circumference thereof.

Also it is apparent that those skilled in the art to which this invention pertains may make various changes in the particular construction and arrangement of parts without departing from the spirit of this invention, and therefore I do not wish to be limited except as hereinafter set forth in the appended claims.

In order to open the package, it is only necessary to grasp the end l5 of the band and exert a pull thereon. This causes the successive folds of foil to first open up and then subsequently the folds l6, l8, l9, and 20. Since the band is interposed between adjacent folds and winds in and out amongst the folds and adjacent layers of the waxed paper, it is obvious that the pull exerted on the band l2 will result in breaking the seal between adjacent folds and cause the opening of the end of the package after which the articles therein may be readily removed.

The advantage of using this arrangement is that the package may be quickly opened without one laboriously trying to separate the folds by prying underneath the folds with the finger nail or the like. Trying to open such a package by the use of a finger nail or similar instrument is not a very easy operation for the reason that the wax holds the folds quite close together and furthermore tends to run and conceal the edges of the folds. Also it is not always apparent just which is the last fold to be made and if one tries to pry open the first fold or any fold less than the last fold, it is more difilcult to open the package.

Obviously if one wished to provide opening means at both ends instead of at one end of the package, this could be done without in any way changing the inventive concept, as it would amount to a. mere duplication, but it is usually only necessary to open one end of the package.

Having thus fully described my invention, what I claim as new and desire to obtain by Letters Patent is: 6

1. A package comprising an article, and a wrapper arranged there-about having a series of pleated radially arranged folds and a band twining back and forth within said folds whereby when extension is exerted on said band, the folds 10 are caused to separate and become unfolded.

A package comprising a group of articles, a waxed. wrapper arranged about said articles with portions thereof folded upon each other in radial arrangement with a continuous element arranged 15 within and amongst said folds in intimate contact therewith, the folds being heat-sealed together to provide a wrapper for said articles which is impervious to moisture.

3. A package comprising a group of articles ar- 20 ranged in end to end relation with a waxed wrapper arranged peripherally about the group of articles and sealed by folding portions of the wrapper in radially arranged folds against the end-most ones of the group of articles with a flexible open- 25 ing element arranged within and amongst the folds for breaking the seal between the folds when tension is exerted thereon.

4. The method. of wrapping articles which comprises the steps of superimposing a flexible ele- 30 ment on a sheet of wrapping material adjacent one edge thereof at a slight inclination thereto with a portion of said flexible element extending beyond one edge of said wrapper, forming said wrapper into a tubular container about the con- 35 tents of said package with the edge of said wrapper which lies adjacent said flexible element at one end of said tubular wrapper, folding the portions of said edge inwardly toward the contents of said package to form a plurality of overlapping folds, and sealing said overlapping folds with a portion of the flexible element protruding from one of said folds in an accessible position.

5. A method of wrapping which comprises the steps of superimposing a flexible package opening 4:; element on a sheet of wrapping material closely adjacent one edge thereo at a. slight inclination thereto with a portion of said flexible element protruding beyond the said edge, shaping said wrapper into a tubular container with the axis of said 50 tubular container substantially at right angles to said edge, whereby the protruding end of said flexible element extends beyond one end of said tubular container, and folding that end of said tubular container from which said end of said 5 flexible element extends to produce a series of .overlapping folds with said flexible element arranged amongst said folds, the said end projecting outside said container in an accessible position.

5. A method of wrapping which comprises the 60 steps of superimposing a flexible package opening element on a sheet of wrapping material closely adjacent one edge thereof at a slight inclination thereto with a portion of said flexible element protruding beyond the said edge, shaping said wrapper into a tubular con ainer with the axis of said tubular container substantially at right angles to said edge, whereby the protruding end of said flexible element extends beyond one end of said tubular container, folding 70 that end of said tubular container from whi h said end of said flexible element extends to produce a series of overlapping folds with said flexible element arranged amongst said folds pro- 7 jecting outside said container in an accessible position, and heat-sealing the folds together.

7. A method of wrapping which comprises the steps of superimposing a flexible package opening element on a sheet of wrapping material closely adjacent one edge thereof at a slight inclination thereto with a portion of said flexible element protruding beyond the said edge, afllxing said flexible element to said wrapper against shifting movement with respect thereto, shaping said wrapper into a tubular container with the axis of said tubular container substantially at right angles to said edge, whereby the protruding 'end of said flexible element extends beyond one end of said tubular container, and folding'that end of said tubular container from which said end of said flexible element extends to produce a series of overlapping folds with said flexible element arranged amongst said folds, the said end projecting outside said container in an accessible position.
