PATENT OFFICE TRUE 1!. AVERY, OF GLENS FALLS, NEW YORK, ASSIGNOR TO UNION BAG & I'APER CORPORATION, OF HUDSON FALLS, NEW YORK, A CORPORATION OF NEW JERSEY WINDOW BAG Application filed June 80,
The present invention relates to improvements in bags adapted to contain or enclose articles or.comm odities of various kinds, it relating more particul. rlyto bags of the kind {1 having a window or open face covered by transparent material through which the contents of the bag will be visible.
One of the primary obj ects'of the invention is to. provide a bag of this kind having a strip extending'across the window near the mouth or open end of the bag and reinforcing the transparent material so as to prevent tearing thereof during filling or other handling of the bag, a tie or closure means being pref- 35 erably associated with the reinforcing strip and serving as means for holding the mouth of the bag in closed condition.
Another object is to provide a bag of this kind which is composed of only two strips of material, that is, thestrip of ordinary paper which forms the major portion of the'bag, and the strip-of transparentmaterial which covers or closes the window therein, and which requires the use of only two seams.
To'these and other ends, the invention con sists in certain improvements which will be hereinafter described, the features of novelty being pointedout particularly in the claims at the end of his specification.
In the accompanying drawings Fig.1 is a perspective view of a window bag embodying the present invention, the bag shown in rear elevation and in open condition and having a portion broken away for clearness iii illustration; y Fig. 2 is an elevation of the-upperend of the bag as viewed from the front, the bag a mouth being in open condition;
Fig. 3, is a view similar to Fig; 2 showing the bag mouth in closed condition;

Fig. 5 is a top plan view of the closed bag showing the tie in fastened condition;
Fig. 6 is aperspective View of the upper end of the bag in closed condition and fastened by the tie; I
Fig. 7 represents a transverse sectlon through the open bag, taken on the 'The body portion 1 of the bag is approxi- 1930. Serial No. 484,967.
line 7--7 of F 1g. 1; Fig. 8 represents a fragmentary vertical section taken on the line 8-8 of F ig. 7
Fig. 9 is a detail erspective view of the reinforcing strip and tie before its application to the bag; and
' Fig. 10 represents a transverse section taken on the line 10-10 of Fig. 9.
Similar parts are designatedby the same reference characters in the several figures.
The present invention is applicable to window bags of various types, it being shown for example, applied to a bag of the so called square bottom type.
In the present instance, the bag comprises a body ortion 1 which is composed of ordinary exible or foldable fiber paper such as that commonly used in the manufacture of paper bags, and a strip 2 composed of thin flexible or foldable transparent sheet material such as .Cellophane or any of the other well known thin transparent flexible sheet cellulose products obtained from viscose.
mately tubular in cross section, it having a wall 3 which forms the front of the bag,
sides 4 which form the sides of the bag and which, in the case of a square bottom bag are pleated as shown so that the front of the bagmay collapse against the back of the bag, and portions 5 opposite to the wall 3 which are separated transversely, leaving a longitudinal ga' in this wall of the tube which forms a win ow opening 6 in the back of the bag. The strip of transparent material 2, which extends throughout the height of the bag, is pasted or otherwise secured to the inner sides of the portions 5 of the bag body so that it extends across and provides a transparent covering for the'window opening in the back of the bag. The strip of transparent material 2 ispreferablysomewhat narrower than the width of the-back of the bag as shown in Fig. 7. The bottom of the bag is closed by doubling or folding its lower end against the back of the bag, forming a flap 7 of the aper composing the body of the bag which ap is pasted to the portions 5 and the lower portion of the transparent material 2 and thereby 1 provides a reinforcement for the transparent material covering the window opening at the bottom of the bag. In applying the invention to bags of the flat type, the pleats 5 are omitted, the front and back of the bag being united directly at the edges, as will be readily understood, and in applying the invention to bags of the so called automatic type, the bottom of the bag may be formed or folded as is common in bags of that type. It will be understood that the bag, in each instance, will be composed of thin flexible material and can be opened, filled, closed and handled in a manner similar to ordinary paper bags. It will also be apparent that in each instance, the bag can be manufactured inexpensively on an ordinary bag making machine, the single strip of material 1 comprising the body of the bag being of less width than usual in making ordinary .bags so that it will not form a complete tube, but will leave a. gap between its longitudinal edges when formed into a tube, thereby leaving the window opening 6 extending longitudinallyfoldable material is extended across the upa per portion of the back of the bag adjacent to the mouth thereof, this reinforcing'strip being pasted to the portions 5 and to the intervening portion of the transparent ma-.
terial 2, it providing a strong reinforcement which will resist or prevent tearing of the upper edge of the transparent material 2 at or near the bag mouth during filling or other handling of the bag. This reinforcing strip preferably has associated with it a tie for holding the bag mouth in closed condition.
'As shown, the tie comprises a narrow strip 9 of thin foldable metal such for example as tin about which the upper edge of the reinforcing stri is rolled so as to enclose it, as will be clear rom Figs. 9 and 10. Before the bag is used, the portion of the reinforcing strip containing the'tie would project above the upper edge of the mouth of the bag as shown inFigs. 1 and 2, but after the bag has been filled and the front and back ofthe bag mouth have been brought together as shown in Fig. 3, the bag mouth is rolled down on the front of thebag about the strip into the form shown in Fig. 4 whereby the bag mouth is completely closed, and the extremities 9 of the tie are then bent back and against the back of the bag to clench them as shown in Figs. 5' and 6, these ends of the matter may be the bag between the portions 5, and covering the window opening by the strip 2 of transparent material, the bag may be made from only two strips of material requiring seams only at the points between the longitudinal margins of the transparent strip and the longitudinal edges of the body portion of the bag, and enabling the strip of transparent material to be fed to the upper side of the usual former and the paper strip for the body of the bag to be fed to the under side thereof, thus facilitating the manufacture of the bags on ordinary bag making machines and reducing the cost thereof because of the relatively small amount of the transparent material required, and moreover, leaving the front 3 of the bag seamless so that it provides a surface on which advertising or other printed.
H The reinforcing strip spanning the window opening and the transparent material covering it and pasted to the transparent material and the. longitudinal portions of the paper body portion of the bag at the margins of the window opening effectually provents tearing or breakingofthe trans arent material at or adjacent to the mout of the b during filling or other handling thereo transparent materials of the kinds commonly used or available, such as Cellophane or material having the characteristics thereof, being more easlly torn or broken than the paper from which the rest of the bag is made, especially when the upper end of the bag, including the transparent win dow-covering material, has a serrated edge or cut-off as shown, and being protected from tearing or breakage by the reinforcing strip. This reinforcing strip also provides convenient means for attaching the tie or closure means to the mouth of the bag and this tie, when fastened, will further strengthen the closed mouth of the bag and will prevent opening or breakage under the force of the contents of the bag during handling thereof.
While I have described the invention as applied to a bag, it is to be understood that the term ba is used in its broadest sense and is inten ed to include other similar or bag-like containers to which, it is obvious, the invention may be applied.
I claim asmy invention:-
1. A bag comprising a body rtion composed of paper and having a wmdow opening in a wall thereof and portions of said wall at opposite sides of said opening extending longitudinally to the mouth of the bag, a strip of trans arent material having the characteristics Cellophane extending across said window opening and secured to said longitudinally extending portions of said wall, said transparent material having a serrated edge at the mouth of the bag, and
a reinforcing strip for said transparent material extending across said window opening adjacent to the mouth of the bag and secured to said transparent material and, to said portions of the bag wall at opposite sides of the window opening. U
2. A ba comprising a body portion having a win ow opening in a wall thereof extending to the mouth of the bag, a strip of transparent material having the characteristics of Cellophane extending across said opening and secured to portions of said bag wall at the opposite sides of said opening,
said transparent material having a serrated V edge at the mouth of the bag, and a reinforcing strip'for said transparent material extending across said window opening adjacent to the mouth of the bag and secured to said transparent material and the portions of the 7 bag wall at opposite sides of the window opening and'havmg a tie attached thereto for holding the bag mouth in closed condition. 1
In testimony whereof I have hereunto set my hand.
