2 Claims. (c1. 220-9) My invention relates to sanitary garbage cans andhas particular reference to garbage cans of a silent or noiseless type;

My invention has for its object to provide a can having an inner container of a sanitary type with a rounded bottom portion so that it can be easily cleaned and sterilized inside and which is supported in an outer container having a cover or lid, tightly and hermeticallyclosing both containers.

Another object of my invention is to provide a pedal-operated mechanism for opening or raising the cover, the pedal being connected with a lever at the bottom of the can; the lever being so arranged that a relatively small movement of the pedal will fully open the cover so as to permit withdrawal of. the inner container. I also provide a spring for automatically closing the cover when the pedal is released and for keeping the containers tightly closed.

Another object of my invention is to provide an elastic or resilient padding of a spongy-material, preferably sponge rubber, under the cover, the spongy material being held by an elastic or pliable diaphragm preferably moulded to fit the edges of both containers. I also provide means to yieldably. and resiliently press the pad against the edges of the containers when the cover is closed, and for this purpose I employ a plurality of springs interposed between the:

under side'of the cover and the pad. With this arrangement it is possible to obtain air air-tight, hermetic sealing for both containers.

My inventionis more fully described in the accompanying. specification and drawing in which-- w ,Fig. 1 is a sectional elevational view of my sanitary can with the cover in the closing position.

Fig. 2 is a similar view of the can with the cover in the opened position and with the inner container removed.

Fig. 3 is a plan view ofthe lever with the pedal,

showing also the supporting bracket.

Fig. 4 is afractional view of a modified cover. My sanitary can consists of an .outer container i open at the top ,and provided with an annular 1 is closed by the cover {3.

rubber base 2 preferably moulded on the bottom flange of the container and provided with rubber legs 3. The upper edge of the container is provided with a round bead 4 preferably made of rubber and moulded or cemented to the edge. An annular 'fiange 5 is .attached to the inner wall of the container substantially below the rim or bead 4 and has an inner rou'ndedor ber ring 9 which rests on the flange 5 supportin the inner container with its bottom raised above the bottom plate I0 of the outer container. This arrangement provides for a noiseless operation when the inner container is placed in the outer container. The inner container is used for collecting garbage, and its bottom portion has a rounded shape as shown in order ,to avoid any inner corners and to facilitate its cleaning and sterilizing. It has a handle in the form of a semicircular bar pivoted by its ends at I2 to the inner wall of the container. The radius of the handle is somewhat smaller than the radius of the container so that the handle can be turned to the side as shown in Fig. 1 when the container The handle can be raised when the cover is removed into the position shown in dotted lines in Fig. 1. v

The cover or lid I3 has a handle M and is provided with a yieldable resilient padding vfor simultaneously closing both containers. The padding comprises a diaphragm i5, preferably made of rubber, rubberized cloth or similar elas- A second diaphragm i1 is placed on top of the pad I6 and is also held at the periphery of the cover l3. The second diaphragm maybe also made of rubber or rubberized cloth or similar material and is provided with projections or pads i8 supporting a number of springs 9 which urge the diaphragm and the spongy pad out-' ward as shown in Fig. 2. The elastic diaphragms with the pad I6 between them tightly fit the edges'of the containers when the cover is closed thereby hermetically sealing both containers. The cover is operated by a mechanism comprising a ring-shaped lever 20 at the bottom of the can loosely encircling the inner container and pivotally supported at diametrically opposite points 2| in brackets 22 which may be made as a single piece with a cross bar 23 attached to the bottom plate H] as by rivets 24. It may be also, of course, welded or soldered. The rin lever 20 is pivotally connected at 25 to one endof a rod 26 whose other end is pivoted at Z'i to a lug 28 extending from the cover [3 near its hinge 29 which supports the cover on a bracket 30 attached to the container l.

Ata point opposite the pivot 25 and midway between the pivots 2|, a pedal 3| is attached to the ring lever extending to the outide through a vertical slot 32 in the wall of the outer container. A hook 33 is fastened to the pedal and engages a coil spring 34 whose other end is attached to a hook or eye 35 depending from the flange 5. The spring tends to raise the pedal thereby bringing the rod 26 down and pressing the cover I3 with its padded diaphragm against the edges of both containers. the cover is fully opened as shown in Fig. 2 when the pedal is depressed, permitting withdrawal of the inner container from the annular flange 5. The handle II is turned upward into the position indicated in dotted lines in Fig. 1 for the withdrawal of the inner container, and is placed sidewise, as shown in Fig. 1, when the inner container is placed into the outer container.

Due to the particular construction of the cover l3, it is not only hermetically tight when closed but is also noiseless and even with a strong spring 34 snap back softly without'any objectionable noise.

A modified cover is shown in Fig. 4. The cover 3 has a lining 36 of rubber or similar material attached to its under surface. A pad 31-is placed under the cover and is preferably made of sponge rubber enclosed inan envelope 38 of rubber, or rubberized fabric or similar' material. Elongated nuts are moulded or inserted into the pad, being retained by enlarged heads 39. Screws 40, passing through corresponding holes in the cover, are threaded into the nuts and hold the pad fast against the cover. The pad may be also cement- ,ed in its place or attached by screws threaded into nuts fastened to the under side of the cover. A retrieving spring (not shown) of an ordinary The lug 28 is so positioned thatconstruction may be provided for the handle ll,

in order to bring it down into an inoperative position, shown in full lines in Fig. 1.

My garbage can has an important advantage of being noiseless in all its operation and is sanitary because the inner container can be easily cleaned and sterilizedand both containers are hermetically sealed when the cover is held in its closing position.

It is understood that my garbage can may be further modified without departing from the 'the inner container, a yieldable diaphragm ex'- tending under the pad and conforming to its shape, a flexible diaphragm covering the upper side of the pad, means to support the pad on the under side of the cover at the periphery thereof, and a plurality of individually acting springs supported between the upper diaphragm and the cover for pressing the pad against the edges of the inner container.

2. A garbage can comprising a cylindrical outer container,'an inner container removably supported in the outer container, a cover hingedly supported at the edge of the outer container, a pad of a resilient spongy material under the cover having an annular groove for the edge of the inner container, a yieldable diaphragm extending under the pad and conforming to its shape, a flexible diaphragm covering the upper phragm and the cover for pressing the pad against the edges of the inner container.
