9 Claims. (Cl. 22445) Milk is frequently sold at the present time in cardboard cartons having the general form of an upright parallelo piped. These cartons, especially in the larger sizes, are difficult to grasp and manipulate.

It is therefore an object of this invention to provide a handle which can be readily and removably attached to a milk carton, which can be simply and economically manufactured, and which will possess a grip portion that can readily be grasped in the hand to facilitate manipulation of the carton.

The upper end of the ordinary parallelepipedal milk carton is usually closed by folding inwardly the upper portions of its four side walls, two opposite side walls being folded in lirst and the other two side walls being folded in next, the folding operation creating pleats the creases oi' which extend diagonally inwardly from the corners of the carton. In providing a handle for use in association with such carton, we employ an elongated grip portion from the upper and lower ends of which two carton engaging elements, conveniently of wire, project. The

lower of such elements has a downwardly offset portion providing a vertical shoulder and extends across the bottom of the carton from such shoulder to the remote side of the carton where it is provided with an up-bent end between which and the shoulder the base of the carton is received. The upper-carton engaging element comprises a pair of arms having in-bent ends adapted to be received in the above mentioned pleats. The in-bent ends may be releasably held in the pleats by the resilience of the arms forming the uppercarton engaging element; but preferably such arms embody portions which diverge toward the carton and are embraced by a link which can be moved toward the carton to draw the in-bent ends toward each other and retain them within the pleats.

The accompanying drawing illustrates the invention:

Fig. l is an isometric view showing a handle in place on a carton;

Fig. 2 is a plan view showing the handle in the course of being applied to the carton;

Fig. 3 is a fragmental side elevation in partial section illustrating the lower portion of the carton with handle applied; and

Fig. 4 is an isometric view of a modified handle removed from association with the carton, the grip portion of the handle being illustrated in dotted lines.

The milk carton to which our handle is intended to be applied has side walls which, at the top of the carton, are folded inwardly to provide a closure. Specifically, the upper portions 11 of two opposed side walls are folded inwardly iirst, and the upper portions 12 of the other side walls are then folded inwardly above them and have their edges sealed together as indicated at 13. The infolded wall-

portions

11 and 12 are joined by pleats, indicated by dotted lines in Fig. 2, in which the upper portion of our handle engages in a manner to be explained hereinafter.

The handle illustrated in the drawing comprises a rigid grip portion 15 from the upper and lower ends of which 2,763,414 Patented Sept. 18, 1956 there project elements adapted to engage the carton. In the handle shown in Figs. 1 to 3, both the upper and lower carton-engaging elements are formed from a single length of wire. At the midpoint `of its length, such wire is bent to form a carton-engaging shoulder 16 of inverted U-shape. From the ends of the shoulder 16, the wire extends in horizontal stretches 17 for a distance substantially equal to the width of the carton and then is offset upwardly to provide a pair of shoulders: 13 opposed to the shoulders 16. From the upper ends of the shoulders 18 the wire extends in horizontal arms 19 for a distance and then vertically upwardly through the grip portion 15. At a distance above the horizontal stretches 17 equal to the height of the carton, the wire is bent inwardly to extend in two upper arms 21 to a point directly above the shoulders 13. From the end of each arm 21, the wire runs outwardly along the upper edge of the carton as indicated at 22; and, at the corners of the carton, the wire is bent inwardly to form hooks 23 which enter the aforesaid pleats.

An alternative construction is illustrated in Fig. 4, Where the portions 16 to 19 of the lower carton-engaging element and the

portions

21, 22, and 23 of the upper cartonengaging element are identical with the correspondingly numbered portions of the handle shown in Fig. l. The difference between the handles of Figs. l and 4 lies in the fact that the latter handle is formed of two pieces of wire one forming the lower carton-engaging element and terminating in two general vertical legs 20a which enter the lower end of the grip-portion 15 and the other terminating in vertical legs 20h which enter the upper end of such grip portion.

The wire element or elements may be united with the grip portion 15 in any convenient manner. For example, the grip portion may be molded of plastic around the wire element or elements, or it may be made of two pieces of wood routed out to receive the wire elements and secured together in any convenient manner.

To prevent relative movement of the grip portion 15 and the wire-portions it engages such wire-portions may be provided with offsets or lateral extensions fitting complementary recesses in the grip portion and serving to locate the wire both longitudinally of itself and about its axis. Thus, in Fig. 4, the ends of the legs 20a may be bent toward each other and preferably welded together. In the case of the upper element in Fig. 4, where the ends of the single length of wire forming the upper element lie outside the grip portion, the center portion of the wire, which joins the lower ends of the two legs 20h, constittutes a common lateral extension for both legs.

Desirably, the U-shaped shoulder 16 lies at an acute angle to the common plane of the horizontal stretches 2l, as will be clear from Fig. 3, so that it will .indent the side wall of the carton which it engages and improve the firmness with which the handle grips the carton. The inher ent resilience of the wire may be relied upon to maintain the hooks 23 in engagement with the pleats at the upper end of the carton, but we prefer to form the upper carton-engaging element in such a manner that its arms 21 diverge toward the carton and to surround such arms with a link 25 which can be forced toward the carton to draw the arms 21 together and hold the hooks 23 in firm engagement.

When a handle embodying our invention is applied to a carton in the manner illustrated and above described, the carton is rmly held in association with the handle and can readily be lifted and manipulated for pouring through the medium of the handle.

It will be understood that the specific embodiments of the invention shown and described are set forth merely by way of illustration, that other modifications are possi- 3 ble, and that the scope of the invention is to be measured by thevannexed claims.

We claim as our invention:

1. A handle for a milk carton7 comprising al generally vertical grip and upper and lower laterally projecting, cartn-engaging elements secured to said handle, said lower element having a horizontal portion adapted to extend across the bottom of the carton and two upwardly projecting shoulders at the ends of said horizontal portion for engagement with opposite sides of such carton, said upper element comprising a pair of opposed hooks movable toward and away from each other to engage and disengage said carton.

2. A handle as set forth in claim 1 with the addition that said upper element includes a pair of arms which diverge away from said grip and terminate respectively in said hooks, and a link embracing said arms and movable therealong in the direction of their divergence to draw them together and hold the hooks in engagement with the carton. Y

3. A handle as set forth in claim 1 with the addition that said lower element is formed from a single length of wire the mid-portion of which is bent into an inverted U-shape to provide one of said shoulders, the wire extending in two horizontal stretches from the base of said U-shaped shoulder toward the grip, each such wire stretch being bent to extend upwardly for a distance to provide the other of said shoulders, thence horizontally toward the grip, and finally upwardly to enter the grip.
