Specification of Letters Patent.

Application mea January 2,1917. seria1N0.'14o,1s5. l

To all lwhom z't mag/concern.'

Be it known that I, JONATHAN PETERSON, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented .certain new and 'useful Improvements in Tobacco- Pouches, of which the following is a specifica-tion.

Mypresent invention relates to Ia bag, pouch, package or similar container adapted especially for goods' of a perishable nature,

particularly those vliable to be affected by atmospheric changes or conditions.

In the present disclosure I have shown the invention employed as a receptacle or containerfor the packaging of manufactured tobacco products, but it is to be understood that the invention is not limited to such particular usc,vas'it may obviously be employed for packaging such other goods or merchandise as may be desired or found advisable.

The present invention pertains moreparticularly to that type of containers which form a receptacle for a commodity prior to vending and subsequent to the sale, the containpr and its contents forming the individual package which retains its integrity from the manufacturer tothe user. Where the commodity is of a form which will de.-

teriorate in the presence of air or moisture,l

the proper packaging of such commodity becomes a serious question since the length of time a package may remain in the hands of the dealer' or dealers, cannot -be determined in advance.

This diiiculty of preserving and maintaining the condition of the commodity as to aroma, iavor, moisture and other qualities, is increased Where the package is comparatively small, must be comparatively inexpensive-to manufacture, and which forms the carrier for the commodity While in the hands of the user. For instance, Where the container is of a type to receive a plug of chewing tobacco, such as isl retailed at a comparatively low'price, the question ofthe cost of the container is important in meeting trade competition asito price; obviously,l

the ability to meet competition is materially increasedv by the ability to place the commodity in the hands of the user with its qualities preserved regardless of the length of time which may elapse between the manufacturing and packaging of the commodity and the time when it is placed in the hands of the final purchaser. v

The present invention is designed to meet these conditions, and at the same time pro- Patented Feb. 27, 1917s:

videa container which is flexible and pliable' tion, the seams, etc.,are so formed and ary lranged as tol prevent the formation and v presence of small leaks,-etc.,thereby eliminating liability of deterioration of the contentswhile the container is sealed, and, 1n

carrying out this feature of theinvention the'usc of a sealing strip, readily broken, is contemplated, such strip closing the container so as to produce the desired result.

To ,these and other ends, the nature of which will vbe readily understood as the in- -vention is hereinafter disclosed, said invention consists in the improved construction and combination of parts hereinafter fully described, illustrated in the accompanying out in the appended claims.

In the accompanying drawings, in which similar reference characters indicate similar parts in each of the views- Figure 1 is a perspective viewof a pouch or container embodying my invention, the pouch being shown as in sealed condition, as when containing a plug of tobacco.

Fig. 2 is a similarview showing the sealedcondition as broken, the sealing strip being shown as partially ripped from the package during the package-opening operation.

Fig. 3 is a sectional view taken transversely through the pouch and sealing strip;

drawings, and more particularly pointed Fig. 4 is a perspective view of the blank from which the pouch is to be made, the blank being partially folded.

Figrii is a view in side elevation of the pouch before the sealing strip is applied.

Figs. 6 and 7 are sectional views taken on lines 6-6 and 7-7 respectively of Fig. 5.

Fig. 8 is a perspective view of a preferred form of sealing strip.

One of the essentials on Which the present invention is based, is the blankwhich forms the body of the bag or pouch, this blank being in the form of a composite sheet preferably rectangularl in shape and doubled upon itself to produce the opposite sides and the closed bottom of the container. The composite sheet is formed ofan outer or backing sheet or layer, preferably of paperl of great tensile strength, and an inner or lining sheet or layer, these layers being intimately united throughout the area of their opposing faces by the use of a cementitious material. The inner or lining sheet is preferably of the paraffin type, although it may be formed of tinv'foil or other suitable material without departing from the spirit of the present invention.

The uniting material is preferably in the nature of a thin film of rubber compound that is applied to either or to both layers in the form of a thin coating, the compound being in a fluid or semi-fluid state when being applied. This material provides a yielding, binding mediunror adhesive, which,

when sufficiently tacky or stickya result" obtained by allowing the coating to be eX- poscd to the atmosphere for a brief period of time-is brought into facial contact with an opposing surface of proper character, and, especially when used with a surface similarly formed, Will cause an intimate union of the two sheet faces When the assemblage is subjected to pressure or heat and pressure.

The composite sheet so formed retains the qualities of flexibility and strength, the uniting film tending to increase these eects, in addition to Which thepresence of the film acts to render the composite sheet air and moisture proof.

As heretofore pointed out, the preferred form of composite sheet has the lining member or layer in the form of a paraffin sheet, a. composite sheet of this type being disclosed in my companion application filed July 7th, 1916, Serial No. 107,906. However, the invention is not limited to the use of such sheet, as the composite sheet may be of the type disclosed in Patent No. 1,137,278

granted to me April 27th, 1915.

In either form of sheet the lining member and the uniting medium is of a form which will render .the composite sheet axir and moisture proof, while providing the additional qualification that the facial uniting of the sheets throughout their opposed surfaces tends to reduce liability of damage to either sheet, such as is present Where the sheets are united at spaced-apart points.

The blank is shown at B in Fig. 4, in

which the backing member of the composite sheet is indicated at 10, and the lining member atI 11,-the thin film being indicated at 12. The blank may be produced in any desired manner, a simple way being to providea rolled strip of the desired Width, and then sever the strip to produce sheets of the proper length. Members 10 and 11 are preferably of equaljvidth, and the sheet is of uniform Width from end to end.

` The outer face of the composite sheet along its side margins, is preferably provided with zones of the adhesive compound, referred to, these zones being indicated at 13, and the sheet folded or doubled upon itself, thus forming opposing sides and the closed bottom of the pouch.

The side seams of the pouch are completed by the addition of strips 14, each having its inner face coated vwith said rubber compound. The strip is then passed over thc side edges of the folded blank as indicated in Figs. 5 and 6, bringing the inner coated face of the strip 14 into contact with the zone 13 at such edge, whereupon the application of pressure, or heat and pressure Will cause the strips to be firmly united to the blank, thereby producing the pouch-like structure.

As heretofore pointed out, the adhesive compound has the qualities of producing air and moisture proof conditions, so that when the inner face of the strip is coated with the compound, the strip is not only strengthened, Without losing its flexibility and ren siliency, but in addition is made practically proof against breakage and leakage on the bending line under pouch manipulations Which result from service conditions. As a result, the side edges of the pouch are not only reinforced by the presence of the overlapping portions of strip 14, but the film effect produced, both between the strip and the face of the sheet and on that portion of the strip which remains unsecured (the bend or fold of the strip) isA such as to preserve theair and moisture proof qualities of the pouch under manipulation. This enables the pouch to be produced without requiring any uniting of the inner faces of the lining member 11 at its edges, thus not only enabling the use of a .param-impregnated inner or lining membera structure which is substantially repellent to an adhesive compound-,butwhich permits the interior of the pouch to be of the full Width of the blank.

To avoid any liability of the formation of small leakage points at the closed bottom `of the pouch, I preferably extend the strip 14 beyond the bottom of the pouch and press the extended portions of the strip into facial contact, thus bringing the opposed adhesivecoated faces of the strip into uniting relation to close any opening which may be presented at such point.

After the pouch has received the commodity-.the -plug of tobacco inthe exam le shown-the pouch is sealed bythe use o a closing or sealing strip l5 which may be of suitable form, but which is preferably of the form shown in the drawings. As shown in Fig. 8, this strip is preferably M-shaped in v cross section, produced by reversely folding the strip, thereby forming relatively de ep side plies ladepending from narrow plies 15b.

coated throughout the area of its inner face,

the coating being of a suitable adl'iesivef-` not necessarily the adhesive compound re-- ferred to. The strip is secured in position by bringing the coated faces of the lower portion of plies 15 into contact with the outer faces of the mouth of the pouch, and

lthen subjecting the strip to pressure which not only" unites the strip to the pouch but also brings the opposing faces of plies 1521 and 15b into connecting relation, forming a pair of wings each of 2-ply structure, these wings being unsecured to the pouch excepting by the single plies 15a. As a result, the strip produces a grasping portion, (the 2- ply wings) and a securing portion'of'multiple-ply form (the plies 15a and the walls .of the pouch) these portions being connected by single plies.

The pouch is opened by tearing or ripping the strip along the single ply connections, the gripping and securing portions offering sufficient resistance to tearingaction to limit the tear or rip to this particular portionof strip 15.4 In 'this operation the mouth of the pouch Amay act as a guide for the line of tear.

Byl this arrangement I. am able to produce the effect of a weakened line structure, without placing on the strip any marks,

scores, etc., which might form leakage points either during the securing action or through manipulation prior to the tearing or ripping action taking place.

To avoidl any possibility. of a leakage point being produce at the mouth end of the pouch when sealed, I preferably provide strips 15 of -a length sufficient to extend. be-

-yond the side edges ofthe pouch, these eX- tending ends being pressed together to close the ends of the strip as is done with the side Ido not herein claim the specific structure of the tearing strip 15, since such claims are The strip preferably of paper and which may be of the material of which the ,backing member is formed, is' preferably presented in my companion application filed February 7th, 1916 Serial No. 76,585.

' While I have herein shown and described `a preferred form of structure, it will be readily understood that variationsor modifications therein may be required or desired to meet the various exigencies of use, and I therefore reserve theright to make any and all such changes or modications as may be found necessary or desirable, in so far as the same may fall within the yspirit and scope of the invention as expressed in the accompanying claims.

What I claim is:
