Abstract
Abstract A device for facilitating filling of elongate flexible trash bags utilizes a generally rectangular sheet of material constructed of a slippery, manually flexible composition having sufficient stiffness to retain itself in a cylindrically formed shape. The sheet is provided with a set of spaced fastenerreceiving apertures adjacent one end edge thereof. A plurality of parallel sets of similarly shaped fastening apertures is provided in an intermediate portion of the sheet nearer the opposite end thereof. Quickly applicable fastener elements are provided for insertion through two selected aligned sets of said fastening apertures when the sheet is manually flexed in curvilinear manner to a helical, generally cylindrical shape. Secured by said fasteners in a desired adjusted diameter, the sheet forms a distender cylinder for use in a novel method for filling flexible trash bags. The distender cylinder in height is only a fraction of the height of the limp trash bag with which it functions in a combination relationship. The distender is first slipped to the bottommost position within the bag, thereby uniformly distending the same and thereafter trash is dumped through the open top of the bag to a level just below the upper edge of the cylindrical distender. Thereafter the distender is slid upwardly above the level of trash and the filling operation is repeated. These steps for elongate large bags are repeated until the bag is filled to the desired level, whereafter the distender is removed and the upper annular edge of the bag is twisted tightly and secured and preferably sealed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
253 words
In combination with an elongate limp trash bag of thin film construction, a positionally adjustable distender and support device for functionally facilitating filling of said bag, said distending and support device comprising; a generally rectangular adjustable distender sheet having a height of only a fraction of the height of said bag when distended, said sheet being constructed of slippery, manually rollable and flexible material having sufficient stiffness to retain its shape when curvilinearly formed into a cylindrical open ended body, said distender sheet having at least one set of fastenerreceiving spaced apertures near one of the end edges thereof and having corresponding spaced sets of fastener-receiving apertures in an intermediate portion of said sheet near the opposite end thereof for selective alignment with said first set of apertures when said sheet is flexed to a helical shape, and readily applicable fastener elements for insertion through the selected two sets of fastener-receiving apertures said fasteners having thin-headed portions for adjustably and smoothly securing the end portions of said sheet with some overlap therein into one of a plurality of cylindrical forms of different diameters, said form and cylindrical body in the first operative positioning of the combination being disposed within the bottom portion of the bag to be filled and smoothly distending said bag and providing support for the same in upright position, the operation of such structure requiring an upper positioning of said distender body through smooth sliding of said body within said body after initial partial filling of said bag with trash.
Claim 2
Dependent Claim
253 words
In combination with an elongate limp trash bag of thin film construction, a positionally adjustable distender and support device for functionally facilitating filling of said bag, said distending and support device comprising; a generally rectangular adjustable distender sheet having a height of only a fraction of the height of said bag when distended, said sheet being constructed of slippery, manually rollable and flexible material having sufficient stiffness to retain its shape when curvilinearly formed into a cylindrical open ended body, said distender sheet having at least one set of fastenerreceiving spaced apertures near one of the end edges thereof and having corresponding spaced sets of fastener-receiving apertures in an intermediate portion of said sheet near the opposite end thereof for selective alignment with said first set of apertures when said sheet is flexed to a helical shape, and readily applicable fastener elements for insertion through the selected two sets of fastener-receiving apertures said fasteners having thin-headed portions for adjustably and smoothly securing the end portions of said sheet with some overlap therein into one of a plurality of cylindrical forms of different diameters, said form and cylindrical body in the first operative positioning of the combination being disposed within the bottom portion of the bag to be filled and smoothly distending said bag and providing support for the same in upright position, the operation of such structure requiring an upper positioning of said distender body through smooth sliding of said body within said body after initial partial filling of said bag with trash.
Claim 3
Independent Claim
199 words
A method for facilitating support and filling of elongate limp trash bags which consists in: forming a generally rectangular sheet of slippery, manually rollable and flexible material into a open ended cylindrical form, said sheet having sets of fastener-receiving apertures near opposite ends thereof, inserting fasteners into mating sets of said apertures to maintain said sheet in said cylindrical form, inserting the above formed cylinder within the lower portion and bottom of said trash bag said cylinder having only a fraction of the length of said trash bag and being of a predetermined diameter to loosely fit and uniformly distend and support the lower portion of said bag, thereafter filling the bag within the confines of said distending cylinder to a level approximating the upper edge of said cylinder, thereafter sliding said cylinder upwardly within the confines of said bag to a position just above the filled portion of said bag and successively repeating the procedure of filling until the bag is filled to the desired level, and thereafter slidably removing said cylinder from the open upper end of said bag and uniformly securing the upper annular edge of said bag to close the same containing the filling therewithin.
