15 Claims.

This invention relates to carrying devices with more particular reference to the combinations with various types of containers of a more improved handle for locking and carrying the same. 1

Objects Among the principal objects which the present invention has in view are: to provide for increased strength in the handle; to enable heavier loads to be carried in the container without otherwise increasing the strength of the material employed; to render the handle more comfortable to the person carrying the same; to distribute the lifting force applied to the handle more evenly throughout the handle; to increase the tendency of the handle to remain locked when once folded to closed and carrying position; .to provide a structure which is readily stamped out, assembled, folded and. used; and to otherwise secure simplicity of construction and operation, and to obtain other advantages and results as may be brought out in the following description.

Description In the specific embodiment of the invention illustrated in said drawings, and referring initially to Figs. 1 to 7 inclusive, there is illustrated a container formed from a blank more particularly shown in Figs. 1 and 2, such that the blank when folded will provide what for convenience may be termed the back and front walls 20 and 2| thereof. It will be understood that these terms are arbitrary for descriptive purposes only. The particular fold in the container provides a transverse crease 22 which determines the bottom of the container when the blank is folded. The opposite ends of the blank, midway between the side edges thereof, are provided with handle patches 23 and 24 secured flatwise upon the blank for obtaining increased strength and stability. When the container is completed, these patches will lie in juxtaposed position. The patches and contiguous parts of the blank are provided with transverse hand or finger openings 25 and 26, which register with respect to each other in the completed container. One of the container walls. for instance wall 2| designated as the front, is provided with an end flap 21, which, when the container is in use, is folded over the otherwise open end of the container for closing the same. Part of the patch 24 for the front wall 2| is'upon the front wall proper and part is upon flap 21. A line of severance 28 extends across the patch so as to give the desired shape of the upper edge of the handle part of the patch. The part of the patch in the flap beyond this line of severance forms a cross bar 29 which is shaped by the line of severance and positioned by virtue of the crease line 30 between the flap and rear line it to fold clear of the finger opening 26 and assume a position between the front and back patches in the closed position of the container as clearly indicated in Figs. 3 to 6.

According to the structure illustrated in Figs. 1 to? now being described, the material forming the finger opening of one of the patches is entirely removed in manufacture, wherea material forming the other finger opening is not severed at one edge, but is left to be folded by the user and form part of the handle and lock. Thus, it will be seen that patch 23 on the back wall 23 of the container has its finger opening 25 completed, with the material entirely cut-away, whereas the other patch 24 of the front wall has a line of severance at the bottom and sides of the finger opening but has the material 3| remaining and integral with the patch at the upper edge of the finger opening. The creasing of the retained material 3| hereinafter referred to as locking member 3|, constitutes a particular feature of the present invention. In its broadest aspect, the creasing is effected so as to obtain an arch formation. To accomplish this result, it will be observedthat a double crease is provided, one line of creasing 32 bowing upwardly and the other bowing downwardly, in other words line 32 may be considered as convex and the other line 33 as concave, the said lines of creasing converging at the termination of the opposite ends of the line of severance around the cut-out part of the finger opening. It will be observed that when looking member 3| is swung upon these lines of creasing so as to be positioned above the finger opening, that both lines of creasing will then arch in the same direction and the material 34 included between the two arcs will be positioned transverse to the front and back lines and.

will constitute an arched surface and the fingercontacting portion of the handle.

Arch 34 performs several functions, one of which is to provide an extended transverse surface for engagement with the hand of the person carrying the container and thus makes the carrying of the container more comfortable since it will not cut into the fingers. The other function is to increase distribution of the carrying force over a more extended area of the handle. The fact that arch material 34 is at right-angles to the plane of the front wall and to the integral part of the patch next said arch, obtains a reinforcement preventing the handle from bending where supported in the plane of the handle. Furthermore, the shape of the arch is one which, as a proposition of physics, provides a stable structure which will both distribute moments of force in the direction of the axis and in the direction of the abutments. A further feature is found in the more secure locking of the closed container. This results from the fact that a certain amount of distortion of the material is necessary in order to fold the free end of the locking member to its upwardly directed position, since folding of sheet material is normally upon a straight line and not upon an arc. However, after the fold is completed, since there are two arcs with intervening arch material therebetween, the fold is complete and stable and will resist, due to thecurvature of the crease, a return to its original extended condition.

It is not to be understood that the invention is in any way limited to any particular type of container or material. I For instance, in Figs. 8 to 12 is shown a container of a different type, and a hand opening of a different construction than the handle arrangement shown in Figs. 1 to 7. Furthermore, this container shown in Figs.

8 to 12- instead of providing an integral locking member stamped from the opening, provides a locking member 35 at the far edge of flap 33 which can be inserted through the juxtaposed hand openings 31 of the two walls of the container after the flap has been folded. Hand openings are however, as in the previously described container, made arcuate at the carrying edge thereof and locking member 35 is secured with arcs of corresponding radius to that of the opening, one, as 33 being convex and the other 39 being concave to provide the width of arch material 43 therebetween corresponding to the structure heretofore described. The arcs 38 and 33 of scoring terminate and intersect where severance of the locking member begins.

In this instance, the locking member is shown with secondary locking ears 4|, 4| at opposite ends thereof below an extended imaginary straight line passing through the points of intersection of said arcuate scorings 38 and 33. All of the advantages of the arch formation heretofore set forth are present in the structure of the several figures just described.

We would point out at this time, that it is not necessary to shape the entire supporting edge of the hand opening arcuately, it being within the scope of the invention, as illustrated in Fig. 13, to have the middle part 42 of the hand opening 43 arcuate at its upper edge and its remaining part 44 to be substantially straight across. Under such formation of supporting edge of the hand opening, creases 45, 46 which include the arch material 41 therebetween, will preferablybe of an ogee formation the middle parts of which bow away from each other. v

The same features may likewise be secured in containers employing double locking members. That is to say, containers may be constructed wherein each face or its patch may have a locking member foldable to finger-engaging position. Of course one of these folding members will overlie the other and therefore only one will actually be engaged by the finger but the other will be contiguous thereto or enclosed therein. For instance, in Figs. 14 and 15 is provided a handle member 48 on the front wall of the container and a handle member 49 on the back wall of the container. From the front side of the hand opening of the front handle member 48 is turned up a member 50 stamped from the hand opening and creased upon double arcuate lines I, 52 with the arch material 53 therebetween. Locking member 54 is stamped from the back handle 49 likewise having single arcuate creases 55, 56, which include arch material 51 therebetween, so that, when the front is closed will be inserted through the hand opening of the front handle 48, and arch 51 of the rearward handle will underlie and be in engagement with the are 53 of the front handle. This will accordingly give double reinforcement to both with respectto the arch transversely to the plane of the container. Furthermore, in carrying out the invention, it will be readily understood that the feature of the double arcuate crease lines as shown in the front handle member 48 in Figures 14 and may readily be employed in the single handle members of the other figures. Also, it is to be understood that one single arcuate crease line may be employed, and a double arcuate crease line converging to meet the single arcuate line and vice versa.

While the foregoing description has been directed largely to the containers utilizing a large enough opening for several fingers in the handle- 2,234,180 tion to containers, it is to be understood that the and projects above-the top of the container when the mp 62 is folded down to close the container. This construction also shows a locking member '3 stamped from the back wall 84 'ofthe cone tainer by which the flap'is held closed. Patch 8| is upon the front wall of the container and provides a'line of severance 65 for providing the finger. opening. From' the ends of the line of which is included arch material 68. The material 68 included between the line of severanceand the concave crease line may be bent upwardly, as shown in Fig. 17, and will thus position the arch 88 at the supporting edge of the finger opening perpendicular to the plane of the container.

With respect to all of the constructions above described, we would emphasize that the invention contemplates the provision of an arcuate supporting edge for that part of the container which constitutes the handle, whether it be by'forming directly in the container or in a reinforcing patch or both. The invention further contemplates the arch as formed by an integral part of the material included between two crease lines which intersect at opposite ends and which have midportions bowing away from each other. The invention likewise presents the feature of this arch being positioned, when the container is being carried, so that the material comprising the arch is perpendicular to the adjacent material integral with the arch material. The invention has thus been shown applicable to the carrying edge of various constructions of containers and handles, but is not limited either to the few examples of handle structures chosen for illustrative purposes herein, nor is it necessarily limited to its application to the carrying edge only of the handle. It may he applied to other edges and to other parts of the container.

Illustrative of this last mentioned advantage of the invention, attention is directed to Figs. 8 to 12 inclusive wherein is illustrated an inverted arch extending across a part of the upper edge of the container when the fiap 36 is turned down to close the container. This inverted arch is obtained by the use of two creases '70, 71 which intersect at opposite ends and provide an arch material I2 therebetween. In the particular construction shown, the front upper edge of the back wall is cut away along arcuate line 13 corresponding to the lower or concave crease line H made in the frontwall. For this reason crease line 1| is immediately behind the arcuate edge 13 in Fig. 8 and will not be seen in that figure. By reference to Figures 10, 11 and 12,it will be observed that the particular embodiment provides a downwardly curved arch 12 at the top of the container and an upwardly curved arch 38 therebelow at the upper or carrying edge of the hand opening.

While we have shown in the several views of the drawings the adaptation of'handle construcgrips and other carrying devices having and above said opening.

construction of such handles is-not to be to that particular use and purpose. itiswellwithin the scope-oi the invention to use such handle construction for other. containers, such as, I
