GARBAGE BAG HOLDER This invention relates to garbage bag holders and more particularly to a device whereby an appropriately sized garbage bag may be suspended in garbage receiving position from a convenient vertical surface such, for instance, as the side ofa cupboard door, or a wall.

Garbage bags made from stretchable plastic materials such as polyethylene, have become a common article of commerce. Certain of these plastic garbage bags have been intended to replace water resistant Kraft paper garbage bags which were previously used in association with receptacles usually suspended from the interior of sink cupboard doors. One serious difficulty encountered with such plastic garbage bags has been the difficulty of maintaining the mouth of the bag open when the bag is placed in such a receptacle so that a person using the same, for instance, to scrape leavings from diner plates, could scrape directly into the open mouth of the bag. Since the old fashioned water resistant Kraft paper garbage bag did not have any critical size relationship to the container in which it was placed there was no effective standardization of sizes for the garbage bag receptacles in which the bags were placed and this lack of standardization of size has carried through in the production of plastic garbage bags. It is well known that the stretchable material from which the plastic bags are made enables the mouths of the bags to be held open if the lip of the bag is stretched and folded back over the upper periphery of a receptacle. However, as the plastic garbage bags of any one manufacturer will not necessarily be of a suitable size to be stretched over the periphery of existing garbage receptacles, the sales of plastic garbage bags have, to a substantial extent, been dependent upon the purchaser having a garbage receptacle of suitable size in relation to the size of the garbage bag purchased. This difficulty has been recognized in the art and it is becoming the practice for producers of plastic garbage bags to supply, along with the bags, a rack providing a suitably sized suspending means for the bags sold along with it.

It is a prime requirement of such racks or holders that they be of minimal cost, be simple to install, effective in use, and adapted for efficient packaging along with the bags with which they are to be used.

Several garbage bag holders designed for this purpose have already been proposed but none has yet been proposed which meets all of the above criteria.

The present invention has as its object the provision of a garbage bag holder for garbage bags made of stretchable plastic material which meets all of the above criteria in being simple to manufacture at minimal cost, capable of being packaged flat together with garbage bags with which it is to be sold, and being simple to assemble and install.

GENERAL DESCRIPTION OF THE INVENTION According to the invention there is provided a garbage bag holder consisting of two pieces, namely, a metal mounting plate formed in a manner to be hereinafter described with socket means at one horizontal edge thereof, and a loop of metal strapping formed in a manner which will be hereinafter described, adapted to be secured with its ends in the socket of the mounting plate to present a horizontal loop having a rectilinear configuration with four sharply pronounced corners over which the mouth of the garbage bag may be stretched and secured to suspend the bag therefrom in mouth-open position for the reception of garbage.

Preferably, according to the invention, the corners are provided on their exterior surfaces with means retaining the stretched over end of the bag against slipping off. Such means may be undulations either scored on the exterior surface of the corners or punched through from the interior side of the corners during the formation thereof, or alternatively some more positive means of retention as will be hereinafter described.

Preferably, the garbage bag holder of the invention is made from corrosion resistant material such as stainless steel or galvanized mild steel, suitable rigid moulded plastic, or extruded aluminum or other extrudable alloys.

The invention and its operation will be more fully understood from the following detailed specification taken in conjunction with the accompanying drawings which illustrate a particular embodiment of the invention by way of illustration.

GENERAL DESCRIPTION OF THE DRAWINGS DETAILED DESCRIPTION Referring now more particularly to the drawings, in the embodiment therein illustrated the garbage bag holder consists of a metal mounting plate 10 and a bag supporting frame 11 formed of metal strapping or like material. As best seen in FIG. 2, where the mounting plate 10 has its back faced uppermost in order better to illustrate the configuration thereof, the back plate 10 is,

folded over upon itself adjacent one horizontal edge thereof at 12, the bent over portion 13 lying in the same plane as the back surface portion 14 of the mounting plate 10 by reason of the forward offsetting at 15 of the mounting plate 10. The folded over portion 13, together with the offset portion 16 form a horizontally disposed socket 17 which is open at both ends and which is adapted to accommodate the

ends

18 and 19 of the bag supporting frame 1 l.

The bag supporting frame 11 is formed from a single piece of metal strapping comprising the two

end portions

18 and 19, the two

spacer portions

20 and 21, the two

back portions

22 and 23 which lie in a plane substantially parallel to that of the

end portions

18 and 19, the two forwardly extending

side portions

24 and 25 and the front portion 26 joining the

side portions

24 and 25.

The bag supporting frame 11 is formed with the sharply

pronounced corners

27, 28, 29 and 30 and these corners are each provided with the scored horizontal undulations 31 which are adapted to prevent the stretched over end of a garbage bag from slipping off the corner. As shown in FIGS. 1 and 2, the undulations 31 are scored on the corners from the exterior surface thereof. Alternatively the undulations may be punched through from the interior side of the corner to take the form of horizontal ridges. This latter form has the advantage of increased strength since the full crosssectional area of the bag supporting frame remains intact, whereas in the embodiment illustrated the crosssectional area is reduced by the amount of material removed in the scoring operation.

As an alternative to the undulations either scored or punched through, the means for retaining the stretched over end of the bag against slippage may be provided by forming a part of the metal of the bag supporting frame 11 in the region of the

corners

27, 28, 29 and 30 into a form adapted to grip the bent over corners of the garbage bag, for instance, in FIG. 3 a portion of the lower edge of the bag supporting frame 11 in the region of the corner 30 is formed outwardly to provide the outwardly projecting lugs 32 and 33. In FIG. 4 the lower portion of the corner 30 is formed downwardly to provide a downwardly projecting portion 34. Various other ways of forming the material of the bag supporting frame in the region of the corners to provide the bag retaining effect will be readily apparent to those skilled in the metal forming and stamping art.

In operation the disassembled garbage bag holder of the invention is assembled by inserting the

end portions

18 and 19 of the bag supporting frame 11 into the open ends of the socket 17 with the upset portion 16 facing the interior of the bag supporting frame 11. Thus the back surface portion 14 of the mounting plate and the bent over portion 13 form a flat surface facing rearwardly from the frame 11. The mounting plate 10 may be secured to a vertical supporting surface by screws extending through

suitable holes

35 and 36. Alternately, and in most instances preferably, however, the entire back surface 14 of the mounting plate is coated with an adhesive (which may be readily packaged and sold in the same package as the garbage bag holder and garbage bags) arid the back surface of the mounting plate 10 is pressed against a vertical supporting surface in the position in which it is desired to mount the garbage bag holder. Various suitable adhesives for the foregoing purpose are readily available on the market and it is not desirable to limit the present disclosure to any particular adhesive, it being understood that any adhesive capable of effectively bonding metal to wood, plastic or painted wood or plastic surfaces will be satisfactory.

It will be observed that in assembling the garbage bag holder of the invention in accordance with the foregoing the mounting plate has a continuous surface facing the supporting frame 11. This is an important feature inasmuch as there are no cracks or crannies in which garbage may tend to collect. For most purposes the garbage bag holder when mounted in position for use may be kept clean and sanitary simply by wiping with a damp cloth and the usual kitchen detergents and/or disinfectants. If more thorough cleaning should become desirable in a particular instance the bag supporting frame 11 may be removed and washed with the dishes and then replaced.
