CONTAINER.

Elmer D. Abramson, Clayton, Mo., assignor to Central States Paper & Bag Company, St. Louis, Mo., a corporation of Missouri Application October 14, 1939,8erialNo. 299,407 1 Claim. (Cl. 229-55) This invention relates generally to containers and, more particularly, to a certain new and useful improvement in containers especially adapted for packing-house products. 1 I

This invention has for its objects the provision of a container for the purpose stated which is in the form of a flexible paper bag of simple and durable structure. which is inexpensive and may be readily and economically manufactured in large quantities, which may be compactly disposed for shipment, which is substantially leak-proof and resistant to .penetration by blood and other fluids normally associated with raw meat and other packing-house products, and which is conveniently usable and efficient in the performance of its intended functions.

And with the above and other objects in view, my invention resides in'the novel features of form, construction, arrangement, and combination of parts presently described and pointed out in the claim,

In the accompanying drawing,

Figure 1 illustrates in perspective a leak-proof bag embodying my present invention in course of construction. Figures 2 and 3 are fragmentary sectionalviews of the partially completed bag, taken along the lines 2-2 and,3-3, respectively, Figure 1; 1 a

Figure 4 is a fragmentary perspective view of the'bag-bottom' at an intermediate stage of its construction; '7 V Figure 5 is a perspective view of the com- Figure 6 is an enlarged longitudinal sectional view of the finished bagbottomf taken approxi-- mately along the line i-6, Figure 5. Referring'now in more detail and by reference characters "tothe drawing, which illustrates 40 includes aninner-member or liner A constructed preferably of oil-treated paper on other suitable fluid-proof flexible material and initially of'oblong-rectangular configuration, overlapped along its longitudinal margins, which are secured flatwisetogether by an intermediate layer of water proof or water-resistant adhesive i extending in a relatively thin somewhat irregular line, as at a, over the outer face f andoutwardly beyond the exposed longitudinal margin lrof the liner A.

Dispo sed in snug-fitting facewise overlying relationship upon and around the. outer face I of the liner A," is an outer member or jacket B securedin dgewise abutting engagement along its inner longitudinal marginc with the outer 'tends flatwise over the lineof abutme tween the margins b, c, for a substantial distance, in the provision of an overlapping section v v e, which is, in turn, secured to the outer face ,1

longitudinal margin of the liner A by means of the protruding line a of the adhesive l'. 'At'fits otherv longitudinal margin d, the jacket ii of the Jacket B by means of a line of waterproof or water-resistant adhesive 2, which extends inwardly beyond the longitudinal margins c in a thin somewhat irregular line as at a, all

in the. provision of a plural-ply open-ended tube 15.

. Along its bottom margin, the tube t is initially closed by suitably applying a relatively wide strip-like coating or film of waterproof or waterresistant adhesive 3 around both the inner and outer faces of the liner A adjacent the bottom margin thereof and pressing the marginal portions of both the liner A and; the jacket B together in the formation of an initial bottom seam I, as shown in Figure 3; As this initial bot. tom seam 4 is formed, the opposed sides of the co-operatively associated jacket-B and liner A are preferably folded inwardly in' any conventional manner in the formation of bellows-type expanding side walls 5'. It will, of course, be unders'tood in this connection that any other conventional type of bag side wall formation may be employed.

Thereupon, a second relatively wide coating or filmof waterproof or water-resistant adhesive i is applied around both sides of the outer face v of the initial seam I and the latter. folded up first to the position shown in Figure 3 and then again folded or rolled to the position shown in Figure 4 and pressed flat in the,provision of a double-rolled seam having a layer or film of adhesive between each itnerface of the bag-form ing materials, as shown in Figure 6.

In use, the raw meat portions, such as livers,

hearts, kidneys, bone tips, rib tips, melts, sweetbreads, and the like are placed in the bag and Y the top rolled down and closed with a heavy rub-- her band or staple, or simply gathered and twist- "ed, as the case maybe. It is usually customary,

of course, to put difierent portionsv in'separate bags for facile handling in the meat coolers. In I any case, the bloodand other liquids which ordinarily exude from the meat will be securely retainedin the bag and will not readily attack the adhesive of the seams for eifecting disintegration and rupturing of the bag bottom, and, finally,

" by reason of the fact that the liner A'is made of oil-treated paper, the blood and meat juices will not penetrate through the side walls of the bag.

Thus it will be evident that, by my present invention, I provide a bag which is rugged, durable, and entirely leak-proof, and which is of simple and economical construction that it may be very readily and easily manufactured. The bags of my present invention are further fiat and compact and may be readily shipped from the point of manufacture to the packing houses without appreciable freight or other handling charges.

It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the bag may be made and substituted for those herein shown and described without departing from the nature and principle of myinvention'.

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

An open-mouthed pinch-bottom bellows type bag having an inner moisture resistant liner jacket and an outer covering jacket telescopically interfitted and secured together in the formation of a plural-ply open-ended tube, said tube being provided with diametrically opposed longitudinally extending inward folds of substantially V- shaped cross-section dividing the tube into Opposed face walls connected by extending side bellows, said tube being provided along its bottom margin with a wide strip-like coating of waterresistant adhesive around both the inner and outer faces of the liner jacket and said side walls and said bellows being pinched together at said bottom end of the tube and being thus adhesively sealed in the formation of an initial transversely extending water-tight end-closure, said end-closure being further provided upon its external faces with a relatively narrower coating band of ELMER D.
