ABSTRACT: A container carrier formed of plastic sheet material having ends integrally connected to an endless band and extending inwardly therefrom, is formed by blanking handle ends totally within an aperture formed by the endless band. The handle ends extend at an angle to the inner periphery of the endless band thereby allowing the ends to lie parallel to one another within the endless band.

PATENTED JUN2 9 WI INV/riNVOR. Ernesf R Cunningham Ronald 6. Owen Their AH'ys CONTAINER CARRIER BACKGROUND OF THE INVENTION 1. Field of the Invention This invention is concerned generally with a package or article carrier, and more particularly with a receptacle-for holding and carrying paint cans or the like.

2. Description of the Prior Art Hcretofore, paint cans or other large containers have been carried by the use of metal bail elements connected to complementary attaching means affixed to the container. This construction has beenfound to be undesirable for a variety of reasons. For example, the commonly used bail is extremely uncomfortable to use by the person carrying it because of the tendency of the small diameter wire to cut" into the hands of the user. The above-mentioned construction also necessitates additional operations on the container itself in placing a complementary attaching means near the rim of the container.

The present invention is directed to a container carrier made of plastic sheet material which includes an integral han-. dle or bail element constructed to'overcome the aforementioned prior art deficiencies.

SUMMARY OF THE INVENTION It is an object of this invention to provide a unitary container carrier which includes an integral bail means. I

It is another object of the invention to provide a container carrier which is adapted to high-speed manufacturing techniques and is easy and convenient for a user to handle.

It is still another object of this invention to provide a flexible carrier for single containers which can be efficiently formed from a continuous strip of thermoplastic material to provide a plurality of interconnected carriers which may be readily separated from one another prior to or during assembly.

The foregoing and other objects, features and advantages of the invention will be apparent from the following more particular description of a preferred embodiment thereof, as illustrated in the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a container carrier embodying the present invention wherein the carrier is shown applied to a large container with the bail portions of the carrier completely connected and extending in an upward direction from the container;

' FIG. 2 is an enlarged fragmentary perspective view of the attachment means between the two handle ends of the container carrier; and

FIG. 3 is a top plan view of the container carrier blank prior to assembly to a container.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, one embodiment of the invention will be described as applied to a paint can or the like, as shown in FIG. 1. Carrier 10 is formed of a flat sheet of plastic material (not shown) which is resilient, flexible and elastic. It is formed from blanking a continuous strip of sheet material into the form shown in FIG. 3. The blanking process forms an endless band 14 having

handle ends

16 and 18 extending integral with the band and within the aperture of the same band. This inwardly extending relationship of the arm with the band is important in that a container carrier having a bail portion, can be constructed out of relatively small areas of the sheet material since the bail portion is blanked from the inner portion of the endless band, which would ordinarily be waste material.

Although polyethylene is a preferred example of a suitable carrier material which is quite resistant to tearing, other functionally similar materials would also be satisfactory. The configuration of the container carrier, in its rest position, enables The container carrier 10 as shown in FIG. 3, has a major and minor axis, and may be in the form of an ellipse or a flattened elliptical figure or any other curvilinear figure defined by an endless band.

The blanking process produces a pair of

handle ends

16 and 18 extending inwardly from points in the vicinity of the major axis and along the inner periphery 15 of the endless band. The

handle ends

16 and 18 are formed at an angle to the major axis of the endless band thereby allowing them to be axially spaced from one another and yet be confined wholly within the inner periphery of the endless band when at rest position. The handle ends 16 and 18 are integral with the endless band 14 and are connected to the inner periphery of the band by connecting portions 28. FIG. 3 shows that the connecting portions 28 are of a generally V-shaped

configuration having legs

30 and 32 emanating from the band 14 and the apex of the V-shape connecting the leg portions to the handle end portions. This V-shaped connecting portion will provide a means for distributing the load from the handle'ends to the endless band. It is to be understood that other structural configurations may serve as a means for distributing a load and that the V-shaped configuration serves as a primary embodiment of the invention.

In use, as in FIG. I, the

bands

16 and 18 are pivoted upwardly to form a generally U-shaped bail element 20 which has a length approximately double that of the length of one handle end. The two discrete

handle end portions

16 and 18 are connected to one another by fastening means 22. The use of this fastening means thus provides an effective unitary carrier structure including a relatively large bail element. The fastening means 22, shown more clearly in FIG. 2, is a preferred embodiment of the invention and consists of a tongue 24 and groove 26. Upon extending the handle ends upwardly, the angular relationship of the ends to the major axis will tend to diminish, due to distortion of the material, and provide an interlocking, overlapping arrangement with one another. It can be seen that the tongue can readily be inserted within the groove and the normal holding stresses will force the tongue into the holding position in the groove and thus present an effective locking means.

I The container carrier 10 can be most efficiently produced by stamping a series of similar blanks from a continuous strip of material (not shown). This carrier is therefore, adapted and designed to be produced on a large scale production line basis.

The container carriers 10 may be readily shipped, either as individual blanks or strips of partially connected blanks, and stored because the extension of the handle ends inwardly of the endless band will provide a structurally sound base for stacking one container carrier upon another. Frangible connections as at 36, 34 may be employed to maintain the handle ends l6, 18 respectively generally coplanar with the endless band 14 prior to assembly. The carrier then may be positioned on a container, such as paint can 12, by stretching the minor axis of the endless band outwardly and forcing the major axis inwardly to conform to the cylindrical surface of the container below the enlarged bead or chime 38. When thus assembled, the carrier snugly receives the complementary container in a container retaining position beneath the peripheral bead structure 38 of a paint can or the like. In this position, the bandle ends I6, 18 will extend upwardly and can be easily positioned into their attaching configuration, as shown in FIG. 2.

The container carrier, when in the position as shown in FIG. 1, will provide a relatively soft and efficient bail means for handling a heavy container, which would otherwise produce an unusual strain on the hand of the individual carrying the container. Upon use of the container, e.g., removing the lid of the container, the fastening means can be easily disconnectedwhen operations would require complete access to the top of the container. The bail means 20 could also be readily reassembled to use as an aid in pouring in a manner similar to existing bail means.

While the invention has particularly been shown and described with reference to a preferred embodiment thereof,

it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention or claims.

We claim: 1. A unitary container carrier of thermoplastic sheet material comprising an endless band, handle ends each being integrally connected to the endless band by a connecting portion, said endless band having major and minor axes and being adapted to receive a complementary container, said connecta complementary container while the handles are arranged to form a generally U-shaped bail when in use and form a compact planar blank when not in use.
