POUCH PACKAGING DEVICE Filed April 19. 1947 Patented Oct. 31, 1950 POUCH PACKAGING DEVICE Glenn H. Whetzell, Hobart, Ind., assignor to Armour and Company, Chicago, 111., a corporation of Illinois Application April 19, 1947, Serial No. 742,509

11 Slaims. 1

This invention relates to a pouch packaging device. The device is particularly useful in the packaging of bacon, such as sliced or shinglestyle bacon in pouches or envelopes. It will be understood that the apparatus is useful for other purposes.

In the attempts to package sliced bacon and similar products, it is found that great diffiiculty is experienced in enveloping the bacon without causing the grease to be spread over considerable portions of the package, thus tending to destroy the transparent characteristics of the bag. Further, the bacon tends to cling or suck itself onto the surface on which it is stacked and cannot be introduced into the pouch without great diff1- culty,

An object of the present invention is to overcome the above difficulties and to provide efficient and rapidly-operated means for placing a stack of bacon slices accurately within a pouch so that the bacon engages the pouch only at the one point where it comes to rest within the pouch. Another object is to provide means for packaging bacon and the like in a container or pouch in such a manner that the bacon does not slide against the surfaces inside the pouch and the slices are deposited in the arrangement in which they were originally stacked. Yet another object is to provide means for transferring a neatly stacked group of bacon slices from the surface on which it rests into a transparent pouch in such a manner that the bacon rests neatly in its final position within the pouch which may then be evacuated to bring the transparent Walls of the pouch tightly about the bacon stack. Other specific objects and advantages will appear as the specification proceeds.

The invention is illustrated, in a preferred embodiment, by the accompanying drawing, in which Figure 1 is a perspective view of apparatus emboclying my invention; Fig. 2, a view similar to Fig. 1 but showing the container or paddle reversed; Fig. 3, a top plan view; Fig. 4, a side view in elevation; and Fig. 5, a perspective view of a fork which may be employed with the paddle for the ready removal of bacon, etc.

In the illustration given in Figs. 1 to 4 inclusive, l designates a standard to which is secured a tapered horizontal post II. The post ll may be formed of steel or other metal welded to the metal standard I!) or, if desired, both the standard l0 and post H may be formed of any other suitable material.

I provide a container or paddle l2 having side 2 walls is and a rear wall M. The front end of the container 52 is open at 15. A tapered tubular handle l6, adapted to frictionally engage the tapered post i l, is secured to the container l2 by welding the bottom extension H to the bottom wall of the container l2, as shown best in Fig. 2.

In order to prevent the bacon from clinging to the bottom wall of the container or paddle 52, I provide the bottom wall with ribs or ridges, etc., which will tend to keep the mass of the bacon away from most of the area of the bottom wall. In the specific illustration given, the bacon [8, indicated in dotted lines, rests upon the raised ribs or ridges I9 which extend longitudinally of the paddle. The bacon is stacked in the usual shingle formation, with the slices of bacon in overlapping relation.

The handle it is provided with diametricallyopposed openings 26, and the openings are connected by a slot extending inwardly and downwardly and forming a hook. With this construction, the fork can be readily hung on a wire and allowed to slide to the place where it is needed for packaging further quantities of bacon, etc.

To further facilitate the removal of bacon strips Tom the paddle $2, I provide a fork 22 which comprisesa wire handle 23 curved to fit and to rest upon the top of handle it, a cross bar 24, and a plurality of tines 25 formed as indicated in Fig. 5. For example, the handle 2.3 and top bar 2d may be formed of t inch wire, and the tines 25 extending downwardly and forwardly therefrom may be formed of inch wire. It will be understood that the size of the wire will be changed depending upon the particular uses to which the structure would be put. It will be understood that the fork 22 may also be formed of strip or other material rather than wire.

formed with blunt ends.

In the practice of the invention, any suitable pouch may be'employed. It is preferred ordinarily to use pouches formed of cellophane and other suitable transparent material. In the structure shown in Figs. 1 and 2, atransparent pouch is indicated in dotted lines by the numeral 26.

Operation In the operation of the device, the paddle !2 may be used with or without the fork 22. In other words, the fork may be placed in position within the paddle, as illustrated in Fig. 1, or it may be omitted, as illustrated in Fig. 3.

Assuming that the fork 22 is placed in position,

In the structure shown, I prefer that the tines 25 be as illustrated in Fig. 1, the fork is preferably secured in horizontal position by pressing the tapered handle It upon the tapered post H. The bacon slices may have been preliminarily stacked upon the paddle and fork or may be placed upon the fork and paddle after the paddle has been secured in horizontal position upon the post H.

With the fork in horizontal position upon the post II, as illustrated in Fig. l, a transparent container 26 is drawn over the paddle and bacon. The handle [6 may then beseparated from the post II and turned completely over so that the bacon will fall upon the lower side of the transparent container. Should the bacon adhere very tightly, the fork may be separated from the paddle by moving it forwardly or downwardly, and the fork may then be withdrawn from the pouch.

Instead of withdrawing the handle Ill completely from the post H, it may be withdrawn slightly so as to permit the turning of the handle to reverse the position of the paddle, and then the paddle may be pressed again into position to hold it in inverted position.

If the paddle is used without the fork, as illustrated in Fig. 3, it is merely necessary to invert the paddle while the same is enclosed by a container and the weight of the bacon will ordinarily be sufiicient to allow it to separate from the paddle.

I prefer to employ a pouch 26 which is closed. on al1 sides except one and, after the pouch is filled with the stacked bacon, to apply vacuum to the open end of the pouch. This operation results in drawing the transparent walls of the pouch 26 tightly around the bacon strips so as to form a compact and attractive package with no smearing of grease thereon. Since the package is substantially free of a grease film, it is clear and the bacon is readily visible throughout its length. The open end of the package is sealed by adhesive, heat sealing, or any other suitable means.

While the ribbed surface of the paddle is usually effective for preventing the sticking of bacon thereon, it is sometimes found that the bacon will not fall off of the surface when the paddle is inverted, and it is, therefore, necessary to use positive means for such removal. In handling such a product, I prefer to employ the fork 22 which has spaced tines 25 adapted to be received in spaced relation upon the bottom wall of paddle l2 and with the handle 23 resting upon the top of the paddle handle [5. The operation of stacking the bacon thereon is the same as heretofore described, and the operation of enclosing the paddle and product with a ba and inverting the paddle is the same as already described. After the paddle is inverted, the handle 23 which extends beyond the end of the transparent bag 26 may be grasped and the fork 22 moved downwardly to transfer the bacon upon the lower side of the bag 26. The fork may then be removed and the bag with its contents evacuated and sealed as heretofore described.

It will be understood that a variety of means may be provided for supporting the paddle !2 in a horizontal position for filling while permitting it to rotate to the inverted position. The means disclosed are simple and are sufficient for illustrating one mode of supporting such a structure for rotation while stabilizing it in the upright and inverted positions.

With the structure shown, it will be noted that the grease-bearing material does not slide along the bag at any time and does not thus transfer to the bag surface a film of grease which would destroy the transparent characteristic of the package wall engaged. By depositing the bacon upon the bag without sliding movement and then by evacuating the container so as to draw the bag snugly about the bacon, it is found that the transparent Walls of the container remain clear and the bacon is visible along its entire exposed surface. The apparatus permits extremely rapid packaging of this difiicult-to-package product.

While in the foregoing specification, I have set forth a single illustration in considerable detail for the purpose of illustrating one embodiment of the invention, it will be understood that the details thereof may be varied widely by those skilled in the art Without departing from the spirit of my invention.
