Patented July 13, 1943 UNITED STATES. PATENT OFFICE 2,324,440 I I WASTE CONTAINER.

Blanche Tormohle n, Chicago, Ill. Application October 21, 1941, Serial No. 415,920

The present invention relates to the combination of a permanent holding receptacle and a plurality of replaceable liners or inserts for holding refuse, and means for holding the liners in place when in the receptacle but permitting ready removal of the inner liner for disposal.

One object of the invention is to provide for the storing in a receptacle of a plurality of liners in such a manner that the liners will lie flat against each other and nested together, and the inner one may be withdrawn when filled, leaving a supply of others into which refuse or other matter may be placed.

Another object is to provide a sanitary means for the disposal of waste which may be collected in the inner liner, which inner liner may be tied up or otherwise closed before complete removal from the receptacle. This is especially important in hospitals and the like where danger of contagion is likely to be prevalent.

The invention also affords means of collecting and removing waste without the danger and annoyance of spreading dust and portions of the Fig. 2.is a vertical cross-sectional view taken .on the line 2--2 of Fig. 1.

contents, either when the container is in use or when the liner is filled and being removed.

A still further object is to provide in combination with a common receptacle a plurality of removable paper containers so designed when held in stock and before being inserted in the container as to be nested one within another in collapsible form and in flattened position, but adapted when inserted in the container to assume the interior shape of the container, such as a rounded or oval contour on the sidesand top as shown in Figure 1.

Another object is to provide an economical combination of collapsible liners which will fit into the receptacle and may be sold at a low price when replacements are needed.

Further objects are to provide a combination of maximum simplicity, efficiency, economy, safety, ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

The invention further resides in the combination, construction and arrangement of parts illustrated in the accompanying drawing, and while I have shown therein a preferred embodiment, it is understood that the same is susceptible of modification and change without departing from the spirit of my invention.

In the drawing:

Figure 1 is a perspective view of one embodi ment of my invention.

Fig, 3 is a vertical cross-sectional view taken on the line 3--3 of Fig. l.

Fig. 4 is a view in perspective of the novel liner or insert.

Referring more particularly to the drawing in which is disclosed an illustrative embodiment of the invention, l represents a receptacle in which I prefer to have an elongated or elliptical opening. Near the top of the receptacle are a series of quarter indented slots lwhich are di -punched from the outside of the receptacle leaving a projecting lip 3 protruding on the inside of the receptacle. The bottom of the receptacle is preferably provided with a false bottom 4 to afford a trough-like base which facilitates the opening and holding of the liner 5 or plurality of liners in the container. It should be noted that the wedge-shaped protrusion or lip 3 nearest the top a of the receptacle has a longer protrusion which enables it to cover all of the upwardly extendiz. edges of the liners 5. In view of the fact the the slots 2 are staggered, as shown in Figs. 1 and 3, the series of lips 3 will provide a series of projections inside the receptacle, and when the liners are pushed in place the upper portion of the liners under the top lips 3, will assume a somewhat corrugated effect, which will act to stiffen the upper portion of the liners and will also facilitate the removal of but one liner at a time.

In practice a number of liners, generally a dozen, are placed within the container. I have provided a pair of oppositely disposed flaps. 6 for each liner, which extend upwardly over the top edge of the receptacle I, and may be bent back as shown in Fig. 1. When the inner liner has been filled and is to be removed, it is a simple operation to grasp each of the flaps 6, and a slight downward push will permit the inner liner 1 to escape the upper lip 3 and thus allow it to be readily withdrawn from the receptacle I withoutdisturbing the remaining liners.

In order to strengthen the liner 1 have provided a horiz tal series of fluted grooves l,

which are preferably located near the topof the liner, and near the bottom I have. provided a series of vertical fluted grooves 8 to strengthen and help hold the liner 5 in upright position.

The fluted grooves I are preferably located on the wider portion of the liner 5 which assists in holding the liner flat against the opening of the receptacle 1 except when the liner is in process of being inserted or withdrawn from the receptacle.

stock a series of liners nested within each other will lie flat and take up a minimum space. The

appearance is shown on lines 8 of Fig. 4 which indicates a very wide flare at the top and a comparatively narrow base. In construction I prefer to fold and secure the base portion I! as shown in Fig. 4.

As so constructed, it is possible to nest a large number of liners one within the other which will permit them to lie flat in stock but will permit them to assume the opened position as shown in Figs. 1 and 3 when a plurality of them are inserted into the receptacle.

As will be noted, the wide flare along the lines 9, 8 of Fig. 4 become much constricted when the liners are inserted into the receptacle because the configuration of the walls of the rigid receptacle forces the sides adjacent-the lines 8, 8 inwardly, thus permitting the top and. upper portion of the liners to assume the oval configuration as shown in Fig. 1. This results in the liners conforming to the oval shaped top and upper portion of the receptacle so that the liners press against the inner walls of the receptacle and remain in open position until a liner is disengaged from contact with the lips I (see Fig. 2) as is done when the liner is to be removed. The configuration oi the liner, as shown in Fig. 4 in dotted form and in solid lines, particularly the slope from the top to the bottom, facilitates the easy removal of the inside liner by reducing the triction between the grooves in the liner and the configuration of the next adjacent liner as well as the lips near the top of the receptacle.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: 1

In a combination of a waste container-and a plurality oi liners for insertion therein, means for holding said liners in said waste 'container and permitting the withdrawal of one liner at a time, comprising a plurality of staggered projections near the top of said container, a plurality of horizontal and vertical grooves in said liners and overlapping flaps said horizontahgrooves being adjacent said staggered projections to retain all the liners except the inner one in the receptacle when the inner liner'is being removed.
