Byron, East Windsor Township, Heightstown, N.J., and Robert E. Hudson, Palatka, Fla., assignors to Hudson Pulp & Paper Corporation, New York,

Filed Apr. 30, 1968, Ser. No. 725,393 Int. Cl. B65d 67/02 US. Cl. 248101 6 Claims ABSTRACT OF THE DISCLOSURE A refuse sack holder for use with disposable bags. The holder supports a disposable refuse sack in an open position so that it may be filled with refuse. The holder has associated clamps which hold the bag in position and a swingably mounted lid to cover the open mouth of the bag held.

This invention relates to refuse handling, and more in particular to supporting paper sacks or the like during the time that they are being filled with refuse.

An object of this invention is to provide a disposable refuse sack holder that can be easily and efiiciently used.

A further object is to provide such a holder that is sanitary and economical.

A still further object is to provide means by which containers that have been filled with refuse can be quickly and efiiciently removed and replaced with empty containers.

These and other objects will be in part obvious, and in part pointed out below.

In the drawing:

FIG. 1 is a perspective view of one embodiment of the invention;

FIG. 2 is a view similar to FIG. 1 showing the holder without the refuse sack;

FIG. 3 is a vertical section on the line 3-3 of FIG. 2, showing one of the clamps of the unit in FIG. 1 with clamp in the sack-releasing position;

FIG. 4 is a view similar to FIG. 3, with the clamp in the bag-holding position and with the cover closed.

Referring to FIG. 1 of the drawing, a disposable refuse sack 2 is held in a position to receive refuse by a supporting unit 4, which is mounted on a wall by a sheet metal supporting bracket 6. Sack 2 is a multi-ply kraft paper sack with one ply made of treated paper, and the sack is strong and resistant to moisture. Supporting unit 4 comprises a rectangular frame 7 which surrounds a rectangular opening 8 (see FIG. 2), which is defined by four vertical walls 10. Flared outwardly from the bottom of walls 10 and integral therewith is a frustoconical skirt 9 comprising two side walls 12 and identical front and rear walls 13. Each of the side walls 12 (see FIGS. 3 and 4) has an integral horizontal flange 15 which rests upon a mating flange 17 of the mounting bracket 6, and each set of flanges 15 and 17 is held together by expansible clamping plugs 19. Supporting frame 6 is attached to a supporting wall (not shown) so that unit 4 is supported above the floor a sufficient distance to permit sack 2 to hang freely.

Mounted upon each of the walls 12 and the adjacent side walls 10 there is a clamp 16 which clamps the top edge portion of sack 2, which has been formed into a cuff 14 in a manner discussed below. Each clamp 16 comprises a clamp frame 18 riveted to walls 10 and 12, and a swinging clamping member 20, which is mounted between a pair of ears 21 of clamp frame 18 by a fixed axle 22. Clamping member includes a locking portion 23 and an integral flat handle 24. Locking portion 23 has a curved cam surface 26 which is knurled to form a large 3,522,922 Patented Aug. 4, 1970 number of small parallel ridges which extend the length of the locking portion between ears 21. The distance of surface 26 from the center of axle 22 increases in a counterclockwise direction from a minimum distance at 27 to a maximum distance at 29. When clamping member 20 is positioned as shown in FIG. 3 it does not project to ward wall 10 beyond the edges of ears 21, and cuif 14 can be readily positioned along wall 10 as shown. However, when the clamping member is swung clockwise (see FIG. 4) surface 26 can be moved into contact with wall 10, except that when the sack wall is positioned as shown, the clamp engages the sack wall and clamps it tightly against wall 10.

In FIG. 3, the clamp is shown in the open position. Handle 24 has been raised to the position shown, thereby turning clamping member 22 in a counterclockwise di rection until there is a space between the locking member and the adjacent wall 10. This space permits cuff 14 of sack 2 to be slid into position along the outer surface of wall 10.. Handle 24 is then moved in a downwardly direction (see FIG. 4), thereby turning clamping member 20 in a clockwise direction until it contacts culf 14 and presses it against wall 10. As refuse is deposited in sack 2, the added weight of the sack tends to pull cuff 14 upwardly along wall 10 and around the upper edge of the wall. Because of the friction and clamping forces between the surface of cuff 14 and the surface 26 of locking member 20, the upward force on cuff 14 tends to rotate the locking member in a closewise direction, thereby pinching cufl 14 more tightly between wall 10 and locking member 20. In this manner, the clamping mechanism responds to additions to the weight of the sack to be supported by clamping the cuff of the sack more securely. When the sack is to be removed, handle 24 is raised, thereby returning the clamp to the open position shown in FIG. 3.

Cuff 14 acts as a support for the sack; that is the cuff and the adjacent portion of the sack are relatively strong, and the sack is of substantantially the same horizontal dimensions as opening 8, so that the sack walls and the cuff extend snugly along the opposite sides of walls 10. The top edges 34 of walls 10 are bent inwardly and flattened to form an inside collar and a rounded top edge. Hence, the reverse fold 36 connecting the cult to the main portion of the sack rests upon the rounded wall edges and there is no substantial tendency for the rounded edges to cut the sack walls. Also, cuff 14 is of substantially the size of walls 10 so that it holds itself against walls 10. Hence, it has been found that the supporting cooperation between the walls 10 and the cuffed end of the sack is sutficiently great that a pair of clamps 16, located on opposite sides of opening 8, are sufficient to support sack 2, even when it has been filled with a large quantity of refuse.

A particular problem that has been encountered in past devices for handling and supporting disposable refuse sacks is the tendency for some of the refuse deposited in the mouth of the supporting structure to not fall into the sack. The portion of the refuse remaining in or beneath the supporting structure after the removal of the refuse sack is often diflicult to remove and creates an unsanitary condition. The cuff arrangement of the present invention prevents any refuse from falling between the disposable sack and the inside of the supporting structure.

An additional feature of the holder, shown is a lid 27 which is swingably mounted at each of its rear corners (see FIGS. 1 and 4) by a hinge formed by a bolt 28 and a bracket 30 which is mounted upon the rear portion of skirt 9. Bolt 28 extends through bracket 30 and a side flange 31 on the lid, and a pair of friction washers 33 and 35 are clamped between the bracket and the flange. Washer 33 is fixed to the bracket, and washer 35 is fixed to the flange, so that the washers give the hinge an antifriction characteristic. Hence, the lid may be swung toward its vertical position and will be held there by the action of the friction washers. As shown in FIG. 4, there is a narrow fiat strip of foam rubber 34 bonded to the bottom surface of lid 27 and extending around the periphery of opening 8 in alignment with the top edges 37 of walls 10. When the lid is closed, the weight of the lid holds it tightly against the top edges 37 of walls 10, and strip 34 is compressed against the fold portion 36 of bag 2. which extends around the top edges 37 of walls 10. In that way, the lid provides a closure from the top of the bag which substantially seals it when the lid is closed, yet the lid may be swung up and will remain out of the way for placing refuse into sack 2.

In installing a sack 2 in unit 4 the top portion of the sack is folded outwardly and downwardly to form the cult 14 which is substantially the height of walls 10. The sack is then positioned with its top portion within opening 8 and with cuff 14 above the level of walls 10. The sack is then moved downwardly and the cuff is placed outside wall 10 and the sack is further lowered until cufi 14 is coextensive with the outer surfaces of walls 10, and the fold in the sack at the top of the cuff rests upon the upper edges of walls 10.

In the illustrative embodiment, sack 2 is a disposable refuse container which is inexpensive to manufacture, convenient to handle and store, and dependable in use. Such sacks may be produced upon equipment which is in common use, and the cufi 14 may be produced at the time of installation into unit 4. It has been pointed out that unit 4 provides a very satisfactory support for the sacks particularly in that the array of edges cooperates with the clamping means and the cuff construction.

The foregoing description of one embodiment of the invention is intended to be illustrative, and not in a limiting sense. It is contemplated that the device described is capable of many modifications without departing from the scope of the invention.
