3 1, a m n |||l United States Patent it i 3,195,719 UNETIZKNG TRAY S Kerry ll. Giesler, Lombard, TEL, assignor to Waldorf Paper Products Company, a corporation of Minnesota Filed Nov. 1S, 1961, Ser. No. 152,442 7 illainis. Cl. 2647} This invention relates to an improvement in unitizi ng trays and deals particularly with a simple and effective means of connecting two objects such as a rectangular carton and a cylindrical can or bottle.

During recent years the use of unitizing devices for connecting a plurality of packages or units has greatly increased. it is relatively simple to unitize a series of objects of similar size and shape. However, when it is desired to combine two containers of ditierent types such as a carton of pancake flour and a bottle of syrup, considerably more difliculty is involved. It is a purposeof the present invention to provide a simple and effect ve unitizer for such objects, and one which may be easiiy An object of the present invention lies in the provision of a tray including a centrally folded bottom panel foldably connected to a pair of side walls. Centrally folded end wall are connected to opposite ends of the side walls. One of these ends is of a length equal to one-half the circumference of the bottle or can. The side walls are of a length equal to the width of the carton plus the radius of the can or bottle. As a result, the carton being of the same thickness as the diameter of the can or bottle, the two objects may be readily connected and supported in side by side relation.

A feature of the present invention resides in the provision of a tray having one end wall substantially of equal thickness to the package and another wall of greater length which can wrap around the surface of a cylindrical object to hold the two containers unitized.

These and other objects and novel features of the present invention will be more clearly and fully set forth in the following specification and claims.

FIGURE 4 is a diagrammatic view of the blank from which the unitizing tray is formed.

FIGURE 5 illustrates diagrammatically the position of the blank after the first folding operation.

FEGURE 6 is a diagrammatic view of the blank after the second folding operation.

The unitizing tray which is indicated in general by the letter A is designed to contain a generally rectangular carton such as B, and a cylindrical object such as the bottle C. While the bottle C is of tapered form, the lowered end thereof is generally cylindrical in shape,

As is best indicated in FIGURE 4 of the drawings, the tray A includes a side wall It), an end wall panel 11, a second end wall panel 12, a side wall 13, and a second pair of end wall panels 14 and 15. These panels are connected along parallel fold lines i6, 17, 19, and 2d and 21. A glue flap 22 is hingedly connected to the side wall 10 along a fold line 23. This glue flap 22 is secured in face contact with the end wall panel in the formation of the tray.

The thickness of the carton B is preferably substantially equal to the diameter of the bottle C. This simplifies the unitization of the two objects, and it is normally Cir i in width to the end wall panels 14 and i5 Eddhfiih Patented July 20, 1965 practical to proportion the package to a predetermined thickness as the width of the carton, as well as the height thereof, can be varied to properly accommodate the desired quantity of product. In forming the tray, the length of the side walls it) and 13 is preferably substantially equal to the width of the carton B as determined by the width of the side wall 24 plus the radius of the bottle C. As a result, the side wall extends across the side Walls such as 24 of the package B and to the center of the bottle C. The combined width or" the end wall panels 14- and 15 is substantially equal to the thickness of the carton B as indicated by the end wall 25. The combined width of the end walls 11 and 12 are substantially equal to one-half the circumference of the bottle C.

Flanges 26, 2'7, 29, and 3d are preferably foldably connected to the upper edges of the walls 10, l1, l2, and 13 respectively along a common line of fold 31. These flanges are of approximately one-half the height of the wall panels. First and second bottom panels 32 and 33 which are connected by a fold line 34 are foldably connected to the lower surface of one side wall such as 13 along a fold line 35. A glue flap 36 is connected to the bottom panel 33 along a fold line 37. The bottom panels 32 and 33 are of equal width and are substantially equal in the formation of the sleeve, the flanges 26, 2'7, 29 and 3d are folded along the fold line 31 to overlie the various side wall panels to which they are hinged, as indicated in FIGURE 5 of the drawings, The bottom panel 33 and the glue flap 3d are folded along the fold line 3 5- so as to place the bottom panel 32 and 33 in superimposed relation and to position the glue flap 36 in position to overlie a portion of the side Wall 13. The blank is then in the position illustrated in FTGURE 5 of the drawings.

The blank is then folded along the fold line 17 so that the side wall 1d will overlie the side wall 13, and the lower portion of the side wall it) will overlie the glue flap 36. Glue has been applied to the glue flap 36 to secure this member to the side wall It Adhesive is applied to the glue flap 22, and the blank is folded along the fold line 21 to adhere the glue flap 22 to the panel 15. This completes the unitizing tray. FIGURE 6 shows the position of the tray just before the final folding operation along the fold line 21.

When the tray A is opened, the bottom and one end wall of the tray are of proper size to accommodate the lower end of the carton B therebetween. The carton B is moved against the end wall panels 14 and 15, and the bottle C is inserted into the other end of the tray, the end wall panels 11 and 12 flexing to encircle the periphery of the bottle. Due to the fact that the side walls and bottom walls are wider than the carton panels 24 by a 7 distance equal to the radius of the bottle, the bottom panels extend beneath the bottle C to the center of the bottle. Thus the bottle is elfcctively supported and prevented from dropping through the tray when the combined package is lifted.

The flanges along the upper edge of the tray provide a finished appearance to the upper edge of the tray and also serve as an effective means of reinforcing the wall panels. By providing the flanges along the upper edges of the tray, the tray fits most tightly about the two obects at a point spaced above the bottom which holds the two objects more ettectively than could otherwise be the case.

In accordance with the patent statutes, I have described the principles of construction and operation of my iin provement in unitizing trays, and while I have endeavored to set forth the best embodiment thereof, I desire to have it understood that changes may be made within the scope of the following claims without departing from the spirit of my invention.
