ROYAL, PHILADELPHIA, PENNSYLVANIA, ASSIGNOR, BY MESNE AS- SIGNMENTS, TO BOYAL-ALLEN-MAIR, ING, OF DOVE-R, DELAWARE, A CORPORATION BAG Application filed. April 11, 1928, Serial No. 269,231, and in Great Britain February 11,1928.

My invention relates to the manufacture of bags and like containers-and comprises an improved construction involving the production of a substantially continuous composite sheet or web from which bag blanks are formed; such sheet having a transparent portion continuous therewith whereby bags produced therefrom may have, either upon one or a plurality of sides thereof, a full length transparent area or zone which will permit inspection of the contents of said bag without the necessity of openingthe same. t

The composite bag-forming material may be made of a section or sections of any suitable form of paper, fabric or the like, in any suitable width, combined \with a section or sections of transparent material of suitable width whereby such composite sheet is provided with a transparent zone or area or with transparent zones or areas, and for this purpose I have'combined one or more sections of paper or the like, with one or more sections .of a perfectly transparent film or pellicle which may be of any well known cellulosic type, cellophane for instance,'or any other suitable and substantially similar material.

The principal object of my invention is to.

produce containers in the form of bags from such improved composite sheet material, which includes at least one part or section which is transpa-rent,'preferab1y highly so, while the other part thereof consists of strips of paper or other suitable material; such bags being preferably formed upon machines of the usual or ordinary type and the trans- "parent materialemployed being susceptible of manipulation by the bag-forming means of such machines without damage or deformation. Bagsof's'uch constrliction are available for use, in the packaging of many articles of'food, delicate fabrics, and other vend ible articles and where, forany reason, it is desirable that the'contents of the container may be viewed and examined through one or more walls thereof without destruction or removal and without handling the article or articles within such container. a

'Theseand other features of my invention are more fully described hereinafter; refermay be made.

sheet material'from which bags embodying Fig. 4: is a diagrammatic view illustrating one manner of assembling and joining together separat'e strips of material to form a composite sheet from which my improved bags may be made.

Figs. 5 and -6 are perspective views of bags within the scope of my invention made from one form of composite-sheet material, and Fig. 7 is a perspectilye view of another construction of bag within the scope of my invention.

Bags having a single transparent portion or zone which extends throughout the length of the wall of such bag or other. S milar eontainer, will have a distinct value in that the presence thereof will permit inspection of the contents and enable the purchaser-to be apprised of the character thereof without han dlingthe sameandthereby soiling the fingers. Such condition is fulfilled if onl a continuous portion of one side or'wa of the bag is transparent and my invention includes a bag havingone wall; a continuous portion of one wall, or a plurality of its walls,

provided with zones or areas of transparent material which extend throughout the length I l of the bag.

In order that the-structure of my improved bag may be more clearly understood and the manner in which it is made fully indicated 1 have illustrated and will describe different constructions of composite sheet material of which bags embodying my invention may be made. This material as illustrated consists of strips of paper and either of one strip of trans arent material as illustrated in Fig. 1, or a-p u'rality of strips of transparent material as illustrated in Fig. 2.- Such composite sheet material is preferably .formed from independent strips ofmaterial, trans- ,bags are made is of a character that may be readily and successfully passed through bagforming machines of the usual type. In practice, the composite sheet material is delivered to the tube-forming mechanism. of bag-machines wherein the outer free edges' of the composite sheets are brought into overlappirig position and secured together by suitable adhesive in the usual manner.

In Fig. 1, of the drawings I have illustrated one form-of a composite sheet from which my improved bags may be made comprising strips of suitable material, paper of any suitable type, indicatedat' A, A, with an intermediate strip B, of transparent material, which may be the cellophane ofcommerce,

or any similar transparent strip, having its edges permanently secured to the edges of said strips A, A. This view illustrates the edges of the transparent strip B asunderlying the edges of the laterally disposed strips A, A, although it will be understood that this arrangement may be reversed, if desired.

In Fig. 2, I have shown anotherform of composite sheet material which may be made up of more than two strips of paper or like I material, in this instance three, indicated at A, A, A, and more thanone strip of transparent material, in thisinstance two, indicated at B, B.

In Fig. 3 I have shown a composite sheet of bag-forming material made up of a single I strip of paper or similar material A and a single strip of the transparent material,

indicated at 13", which may be employed for the making of bags within the scope of my invention. r 4

In Fig. 4 I have illustrated, diagrammatically, one manner in which the composite sheet of bag-forming material illustrated in Fig. 1 may be produced; 1 and 2 representing rolls ofpaper, .fabric or-other suitable ma terial, delivering the strips indicated at A, A, and 3 a roll delivering the strip of transparent material, indicated at B. Suitable adhesive-applying disks 4 disposed in-a receptacle 5, may be arranged to engage the edges of the strips A, A, and apply a film of adhesive whereby they may-"be joined to the edges of the intermediate transparent section B; the several connectedstrips forming the composite sheet material preferably passing between a'pair of rolls 8 and 9, whose pressure will insure the edges.

Although I permanent adhesion of have described the composite proved composite material, those shown in I said views arerepresented as made from. composite sheet material of the characterillustrated in Fig. 1; the bag shown in Fig. 5, having its continuous transparent area or zone b centrally disposed, while the bag shown in Fig. 6, has its continuous transparent areaor zone 6' at one side of its face. In the latter form, the space adjacent the continuous transparent portion of the bag face may receive printed matter indicating the contents of the bag, or other informatlon, although it will be understood that such transparent material may also receive printed matter.

a The package I),- illustrated in Fig. 7, comprises a bag of a well known type, made ofcomposite sheet material of the character illustrated in Fig. 2, which comprises a plurality of strips of paper or other suitable mate rial and a plurality of transparent strips.

Preferablythese latter strips should be highly transparent. I The transparent portions of the composite material employed for this bag are so disposed that the finished article will have oppositely disposed zones or areas b of transparent material, extending the full length of the bag, through which the contents of such bag may be viewed; while the other walls may receive printed matter.

While I refer to the use of strips of paper in combination with strips of transparent material, it will be understood that the less transparent portion or portions of the composite sheet material from which my improved bags are made may be of any suitable strip of paper, fabric, or the like, and that.

the transparent portion or portions may be of any suitable material, acellulosic or other body, cellophane for instance, having prefera-bly a high degreepf transparency and capable of permanent engagement with the paper or other strips constituting the other part of such composite material by-;Jthe aid of asuitable adhesive.

I do not wish to be limited to the use of cellophane as the transparent portion of the composite bag-forming material meniioned because I may employ the socalled crystalline or glassine of com-.

site sheet material of-passing through a a'g machine of the usual or ordinary type wherein such composite sheet material may be fashioned into ,the usual tubes from which bags of any commercial form are produced. I claim: I

l. A paper bag made of a section of a composite sheet consisting of two strips of flexible material and a transp'arentstrip of flexible material so arranged that one edge of each of the first-named strips is in opposed spaced relation to one edge of the other strip with the transparent strip located between and secured to said opposed edges; the outer edges of said composite-sheet being overlapped and permanently secured together in v developed into tubular form; sald compos-.

tube formation and all of the; strips of said composite bag being of substantially the same length. a

2. A paper bag made of a compositesheet ite sheet comprising a plurality of strips of flexible material and a transparent strip of" flexible material in parallel relation; said parent strip centrally of and extending the full len th of one face of the bag.

6. A ag for holding and displaying contained articles, comprising transparent and apaque strips of substant ally equal length In witness whereof I ,have signed this specification. a
