'ronAcco BAG.

' Application filed August 7, 1922. Serial in. 580,055;

To all whom it may concern:

Be it known that I,-WI1.LIAM L. TAYLOR, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton "and State of Ohio, have invented certain new and useful Improvements in Tobacco Bags, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings forming part of this specification.

My invention relates 150' bags, such asare used for .tobacco, although, of course, the bags could be used forany desired purpose.

Inthe production of a one-pieceba for tobacco, it. is customaryto provide a single blank having one half wider than the other. to provide flanges or tabs which can be fold ed in over the blank. To these tabs cement is applied and the narrow end of the blank laid down over the tabs, so as to become.

cemented thereto and thereby forming a onepiece bagopen at one end.

Ithas been found desirable by me to form bags for articles which must resist climatic conditions of moisture, penetrating odors and the like to make them from paper which is of plural asphalt.

The asphalt makes a perfectly insulated.

The difiiculty informing a perfect bag of this substance lies in the factthat itsadhesiveness is not perfect, and that incold weather it becomes hard, and in hot weather, soft to a certain degree. Thus any asphalt pasted paper is likely. to separate under strain, so as to permit the webs to part, and if this should occur in a bag, it would make it useless for the purpose of'a container of semi-permanent nature.

It is evident that there is exposed to strain in the single bag which-I have briefly described above, the edges of the narrow ends, and that portion of the tabs to which the narrow end is cemented.- The edges of the narrow end are exposed and are subject to peeling back to expose the asphalt layer, and the tabs are likely to separate from the op-.

posite wall to which they are glued and permit the bag to come to pieces.

It is my object to so form the bag of my invention that neither of these dangers are likely to occur, and in which the asphalt filler is not likely to show at any exposed for ..a single bag.

ply and pastedtogether with I gether.

edges of the paper, and thus to smudge over onto the face of the bag, making it unsightly.

These objects and other advantages to be noted I accomplish by that certain construction and arrangement of parts 'to' be hereinafter more specifically pointed out and claimed. 1

In the drawings, 1 Figure 1 is a plan view of the bag blank Figure 2 is a section on the line 22 thereof, enlarged so as to show the nature ofthe interposed layers. Figure3 is a perspective view of the completed bag.

Referring to the shape of blank for a single tobacco bag having the

ends

1 and 2, with the tabs 3 located at the sides of the end 1. In forming up the bag, the end 2 is folded toward the end 1 across the center of the blank, with the tabs folded inside between the two fends of the blank. Cement is applied to the tabs orthe edges of the end 2, so that the tabs, and the end 2 are secured together, thereby forming asingle wall bag.

The paper Lemploy is formed of plies A and B, beween which is a binding 'layer of asphalt 4. This asphalt is of a tacky and resilient and odorless and tasteless quality and binds the webs of paper to- Instead of paper I might employ fabric or foil, although this willnot ordinarily be called for in bags of this character which are made by machinery in great quantities, and used .for scrap tobacco, cigar pouches, and the like.

blank, I employ the usual I tudinally of the sheet as indicated by the areas within the dotted lines 6 in Figure 1 v and as shown in the unshaded portions 6 in Figure 2. When the web is cut into blanks, these bands are dis osed' along the edges of the narrow ends 0 the blanks and extend through the wide ends of the blanks. Other bands of suitable cementitious material are disposed along the edges of the tabs 3 as indicated by the areas included between the outer edges of the tabs 3 and the dotted lines indicated at 5 in Figure 1, and as shown by the unshaded portions 5 in Figure 2;

If cement of different color than the asphalt were to be used for the areas the-ap arance of the outer sides of the bag mig t be marred with streaks so that in order to avoid this l have found it preferable to mix a small amount of black material with the cement to' give the body of the paper in the bag the same appearance throughout. A suitable cement for the areas indicated at 6 maybe provided by mixing casein or varnish with asphalt, and a similar material may be used for the areas indicated at 5.

Thus I show the narrow bands of casein or varnish 6, which may be applied together with enough asphalt to give a black color, or which may be so applied that the asphalt can become transfused into the casein or varnish sufiiciently to change its color, but not sufiiciently to change its strongly adhesive nature.

I have not limited myself to the use of particular cementitious material for the tab portions. Gasein. and varnish have waterproofing qualities and could be used instead of asphalt, except for their high cost. Also they could be used in a wide band, so as to take in the tabs and narrow end edges also, except for its high cost.

A good varnish mixed with a portion of asphalt tr colored black, or filled in some other, way to giveit color and bulk, can be used in cmaller quantities than the cement. Thus the narrow streams sufiicient to make permanent the edges of the narrow ends of the tab edges cemented. wherethey are protected by the overlap of the narrow end of the blank, and a narrow stream of'casein or varnishrunning along the blank so as to safely cement. together the edges of the narrow blank" where exposed, gives me a thoroughly insulated bag, and a bag which isclean throughout and formed of a. single piece capable of being-made up automaticall and very rapidly in s ecial machines ma e for the purpose. Suc machines are -'now in use and have been for many years.

The characteristics of varnish or casein,

which are vegetable and animal gums .re-

nezis aee spectively and which makethem applicable to my purpose is that they are gummy substances and that they have insulating qualities. If wish to include in the term varnish or casein such gummy, insulating substances as may be applied to a web of paper, fabric or foil, together with some asphalt or in the absence of any asphalt alon the lines of the gum stream, and which Wlll serve as an adhesive of permanent nature better than asphalt.

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

l. A bag formed of a blank of foldable material, said blank having one end folded over, inturned tabs on the other end, and said first mentioned end cemented to said tabs, said blank having a plural ply nature between which plies is a binding, interposed layer of asphalt or like substance, with certain portions of the blank having interposed streams of varnish, casein, or the like at the exposed lateral edges of the completed bag, and saidblank having a nonasphaltic cement at the edges of the inturned tabs.

2. A blank for bags comprising a single member having a wide end and a narrow end, the extending portions of the wide end to serve as inturned tabs, said blank being formed of two plies, at least, of paper,

fabric or foil, and the plies united by a binding interposed layer of asphalt or like substance, with a narrow stream of varnish, casein or the like extending between the plies lengthwise of the blank, so as to lie at the edges of the narrow end thereof, and with the as halt absent from lines extending lengthwlse along the tab portions of the blank and in its place a permanent binding interposed band of suitable cement.

3. A blank for folding lengthwise to form a bag comprising a wide end and a narrow end with extended portions of the wide end adapted to be folded to form sealing tabs and the blank formed of plies united by a binding interposed layer of asphalt or the like, with a narrow stream of varnish, casein or the like disposed between the plies extending lengthwise of the blank along outer edges of the narrow end of the blank and extending through the wide end of the blank and means for securing the tabs and the narrow end of the blank together, to form a bag.
