BAG SUPPORT AND SCOOP BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to support devices for holding open the mouth of a flexible container and in particular to such a support device including a scoop portion.

2. Description of the Prior Art Light plastic bags have come into prominent use for trash, garbage, leaves, and the collecting and storing of all manner of lightweight bulky items and materials. When one person tries to hold one of these bags, it is very difficult to fill it at the same time. To overcome this problem, various racks have been made for supporting the entire bag with its mouth open. These racks often have some form of hoop over which the lip of the bag is secured in some manner. These racks are not generally suited for scooping leaves into, but rather the leaves must be lifted and dumped in. lfjust a hoop were used at the mouth of a bag, it would help a great deal, but the bag tends to collapse behind the hoop so that it is sometimes difficult to push an adequate amount of leaves or other material in before having to raise the bag and shake it down.

SUMMARY OF THE INVENTION In accordance with the present invention, a bag opening support with scoop is provided which not only facilitates the moving of material toward the bag mouth, but also provides an extended surface for holding an increased bulk of material while the bag is lifted for shaking the material down to the bottom. For this purpose the present invention provides a hoop for supporting the bag lip together with clips for clipping the bag lip to the hoop. A number of the bag clips are made integral with a semirigid scoop which thus acts essentially as part of the bag. A feature of one embodiment is a flexible member holding the individual clips together with the scoop so as to reduce the likelihood of losing individual clips. Thus, it is an object of the invention to provide a novel bag opening support combined with a scoop.

Further objects and features of the invention will become apparent upon reading the following description together with the Drawing.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a plan view of the bag opening support hoop with scoop and clips attached.

FIG. 2 is an end elevation of a plastic clip.

FIG. 3 is a section taken along 33 of FIG. 1.

FIG. 4 is a partial end elevation of a clip integral with the scoop of FIGS. 1 and 3.

FIG. 5 is a plan view of a second embodiment of the bag opening support hoop with scoop and clips attached.

FIG. 6 is an end elevation of a second embodiment of a plastic clip.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Plastic disposal bags are made of thin soft plastic in other side is sealed across. The bags so made tend to lay flat, and in order to hold the open end spread, FIG. 1 depicts hoop 10 about which the lip (top edge) of the bag may be wrapped. Hoop 10 is readily molded from polyethylene or similar plastic as a continuous tube. The tube is bent into a circular hoop and secured by plug 12 over which the ends of the tube pass. Plug 12 is depicted as a wooden dowel to which the plastic may be cemented or riveted. As depicted, rivets 14 are provided which pass through the plastic tubing and the dowel to be headed over on both sides. Instead of the wooden dowel, a plastic or metal plug can be used which may engage the tube by lands and grooves, knobs and apertures or other ready method.

Four clips, 11, illustrated in end elevation in FIG. 2, are made ofa stiff plastic having a longitudinal opening in the bottom that will spread under pressure to admit hoop v10 into a longitudinal recess. Thus, clips 11 are depicted clippedover hoop 10 at regularly spaced intervals. Raised ridge 18 extends longitudinally along the top of each clip 11 for grasping.

Scoop l5, integral with additional four clips 16, has a length in the range of one third to one half the circumference of the hoop and is depicted in FIG. 1 as extending over of the circumference. Scoop 15 is shown in more detail in FIGS. 3 and 4. FIG. 3 shows a phantom portion ofa supported bag 17. Scoop 15 is made of plastic such as polyethylene, polypropylene, polyester or polystyrene. For convenient use and storage, it is preferably about 8 to 10 inches high, about 1/16 to 6 inch thick and is molded flat. Clips 16 are essentially the same as clips 11 except they are integral with scoop 15. Preferably, additional'support struts 20are molded in also to add some stiffness and additional strengthening between clips 16 and scoop 15. These struts, oriented perpendicular to the axis of each clip 16, run from the maximum bulge of the clip up into the scoop. While the strut length is not critical, a length of 1 to 3 inches is suitable. While integral molding of clips 16 with scoop 15 is deemed preferable, clips 16 may also be made integral with the scoop by thermal or other bonding technique.

While for most purposes the clips provide sufficient resistance to rotation for practical use of the scoop, additional rotation resistance is readily obtained by circumferential splines (not shown) around the circumference of hoop 10. Mating splines (not shown) on the interiors of clips 16 will strongly resist rotation of the clips and connected scoop.

Again not critical, suitable sizes for the bags used generally for leaves and similar refuse are an 18 inch I. D. hoop l0 and a tube diameter of to

inch D. Clips

11 and 16 are made of a size to fit hoop 10 with a length of about 1 to 2 inches. Since substantial flexural. strength is required, particularly in

clips

11 and 16 and in scoop 15, the plastic thickness for these members is determined by the particular plastic utilized and the available specification tables to provide the desired flexural strength.

While scoop 15 is preferably made flat, it will be understood that it at least partially conforms to the curvature of hoop 10 when attached.

FIGS. 5 and 6 depict a further embodiment of the invention incorporating a plastic strip 24 as a connecting strand for all the clips as well as scoop 15. This serves as an aid both in packaging and in ultimate use by insuring that the clips so not become separated and misplaced or lost. In FIG.'5, clips 22 all have plastic strip 24 either integrally molded or otherwise bonded to the upstanding graspable portions. Cross-section 25 of plastic strip 24 depicts it as having a circular cross-section about one-fourth inch in diameter. Rectangular or oval cross sections would serve as well, it being primarily desirable that strip 24 is strong enough to avoid accidental breakage in normal use. Clips 21 at the ends of scoop 15 are slightly different from clips 16 only in that the ends of plastic strip 24 are molded or otherwise bonded thereto. While strip 24 is depicted as connected to the top upstanding part of clips 22, it will be seen that this strip may be connected at many alternative points inside or outside clips 22.

While the invention has been described with respect to specific embodiments, many alternative variations are obvious to those skilled in the art. For example, scoop 15 may take on many shapes both in outline and in curvature without departing from the spirit of the invention. Likewise, hoop can readily be square or rectangular. Accordingly, it is intended to cover the invention as set forth within the full scope of the appended claims.
