Abstract
BAG STAND CONTAINER
ABSTRACT
A free standing frame and lid assembly has been developed for supporting garbage bags during filling which offers special advantages of rigidity, ease of bag attachment and removal, cleanliness and simplicity compared to other types of stands or containers. Although it is known that the principle of a lid and frame assembly for supporting an open plastic bag is in use, attached to cupboard doors or walls, etc., the proposed invention requires no such support during use and therefore can be transported about during filling. This is an advantage when cleaning up open areas.
In addition, the simplicity of the frame design and clip-on lid attachment as compared to other methods not only permits low cost to manufacture, but also provides a garbage container which can be easily washed and kept clean. This advantage of a clean frame and a specially designed clean tight fitting lid could be important for use in hospitals and other institutions. Finally the ease of attachment and detachment of a filled bag without special clips or of having to lift the bag for removal when filled, are special advantages made possible by the unique combination of a two legged stand supporting a four cornered frame opening designed for a given side of plastic garbage bag.
PURPOSE OF THE INVENTION
The purpose of the invention is to provide a structural frame for supporting the open top of a plastic or fabric bag during filling, and of sliding the filled bag out of the stand without the necessity of lifting the bag.
A second purpose of the invention is to provide a device for handling garbage which is inexpensive to make, light in weight, odourless and sanitary.

Description
_A~ LL55~c~ Page 2 DESCRIPTION
The proposed bag stand consists of a two-legged.frame configuration made by bending tubular or solid bars into two self-supporting "U" shaped sections, Figure 1 of accompanying illustration, and attaching said two "U"
sections back to back by means of suitable fast~ners or welds, Figure 2, to foxm a frame stand to which a specific sized bag may be convenien-tly attached, Figure 3. The said "U" shaped sections consist of four 90 "U" bents, see hatched sections, Figure 1, each having a single back piece, see Item 1, and two parallel flange pieces, see Item 2, formed by making two smooth radius bends, see Item 3, of the same material. The four "U" bends are joined to one another by means common flange sections, Item 3 and the con-figuration closed by joining the material ends at joints, Item 4, thus forming the said "U" shaped section Figure 1.
The assembly and attachment of said "U' shaped sections in pairs back to back forms a stand, Figure 2, having a rectangular frame at the top, see Item 5, over which the edge of a bag opening may be attached, Figure 3, two vertical legs, Item 6, attached to the two opposite sides of the said top frame and a similar rectangular frame, see Item 7, which rests on the floor and is joined to the two vertical legs by means of continuity of the frame bents as previously described.
This continuity in the forming of the U bents by means of 90 radius bends, Item 3, as described and their connection back to back by means of a weld or fastener, Item 3, forms a bag stand having exceptional properties of tightness and strength.
The size of the top rectangular opening, Item 5, and the height of the frame have been designed to suit a specific size of plastic bag - or a cloth bag having a draw string closure.

~his o~ening rust -be larger than the circumference oF the open bagr so that the bag may be held by a short r1m~ see -te~ ~ folded do~ln over said rectanF;ular opening.The outside clrcumrerence of the opening should be a minimu~l of 5% and a maximum of 20~ but preferably ~
larger than the said circumference of the plastic bag to be supported.
In addition to the sa d ~lastic bag stretch over the said frame openlng, support for the bag is also assisted by local pockets of stretched pl&s-tic at the four corners of the frame. The said corner stretch of ~he plas-tic ~aterial must ~e controlled to some ex-tent since, if the corners ~vere sharply pointed the plastic wcuId tear and conversely if the circurference were completely round like a hoop or oval the plastic ba~ ~ould more readily slide down off the frame. It has been found th~t a corner r~ius varying from 1" to 3" but preferably 2"
is effective in securing a 1~ mil polyethylene bag to a rec-tangular tubular frame. A plastic bag can thus be supported by pockets formed in the plastic at the four cormers, see Item 10, specially sized for this purpose. Cloth bags, i made with a sewn seam and a short vertical split can be supported in a similar manner by folding the seaned edge down over the top rectangular o~ening and par~ially tightening the draw stringO As can be seen, the shorter perimeter, see Item 11, afforded to the turned down edge of the ba-g~ is made possible by the geometr~ of the two legged frame.
In addition to the support of the bag by the size and shape of the top frame described above, the dimensions of -the stand are designed so that a specific sized bag when fllled will res-t on the bottom rec-tangular opening, as shown in Figure 3. This permits l~teral sup,ort by the two vertical legs and also stabilizes the frame by the weight of the ba~ and contents on the bottom frame, section 7.
~y these principles, the common 1-~2 mil thick, e.g. 26" x 36" poly-ethylene bag may be conveniently filled with garbage and detac~led fror the frameO .~lso a more substantial cloth bag may be filled with ~et laundry and detached in a sir.ilar manner. i~s illustrated ir ~igure 3, a hirged lid, see Item 127 nav be conveniently clipped to the frame utilizing part of -the f~ame for the hinge pin in conjunction with att-ached clips, see lte~l 13, to the lid.

Advant~Les The two legged bay stand previously described exhibits a number of advantages in design and use over any other known system for filling bags. These are as follows: The "U"
shaped sections when attached back to back form what may be classified by engineers as a rigid frame structure.
Such structures which have both ends of the two ver-tical supporting members rigidly connected to a lateral part of the frame with approximately the same strength are especially suitable to resist side sway and collapse.
A second structural advantage contained in the design is due to the attachment of the two said "U" sections in which the two vertical supports act jointly rather than individually in resisting lateral bending as compared to a four legged stand of the same materials.
A third structural advantage of this configuration is that a major part oE the weight of a filled bag rests on the lower rectangular frame which in turn rests on the floor. This weight provides stabili~y to the structure against tipping which increases with the weight of material in the bag.
A fourth advantage of the configuration is in the easy attachment and securing of the top of the bag around the said top frame opening by mean~s of stretching a portion of the top of a plastic bag around the frame and folding it down.
The top edte of the bag can thus be held without the use of clips, etc. by means of a combination of the stretch exerted by the difference in size of the bag opening and the top frame combined with the four smooth radiused corners which tend to form stretched pockets in the plastic material thus increasing the folding capabilities of the bag to the frame. This method of atta~hment is fast and reliable.
This same method of edge fold down can also be used for BAG SlAND CONTAI~IER Page 5 _ materials that do not stretch, providing there is a seam sewn around the top through which a draw string can be employed and there is a short vertical slit at the top. As can be seen by the said sketch, the securing of the bag to the top opening is greatly facilitated by the two legged support system permitting a smaller perimeter of the edge of the bag, see Item 11, after it has been folded over the top of the frame as opposed to a four legged support frame or a container having conventional walls which would not permit a reduction in perimeter of the top of the bag after it is folded down over the top edge. A fifth advantage of the two legged bag stand is in the easy method of bag removal in which filled bag can simply be detached from the top frame, tied and then pulled out from between the two vertical supports without having to lift the bag. Under certain conditions of heavy garbage or bulky material, this method of removal can be a definite advantage in material handling, no-t possible with a four legged stand or a conventional garbage container. A sixth advantage is the said garbage bag stand has less surface area and is therefore more easily cleaned than the conventional garbage can. A seventh advantage of the said bag stand is in the easy method of attaching a clip on hinged lid, Item 12, in which the frame itself forms the hinge Pin for a clip attachment, Item 13, to the lid. This allows a tight enclosure preventing garbage odours.
