A ril 14, 1953 w. H. GRAVATT DISPOSABLE LINER FOR GARBAGE CANS Filed May 25, 1951 Fig. 3

Will /am H. Gravatf INVENTOR.

BY all you; Em

Patented Apr. 14, 1953 UNITED STATES PATENT OFFICE 2 Claim 3.

This invention relates to new and useful improvements and structural refinements in garbage can liners, and the principal object of the invention is to facilitate convenient and expeditious cleaning of a, garbage can, that is, removal of the contents thereof, without the necessity of lifting and. tipping the can.

This object is achieved by the provision of a disposable liner for the garbage can, the arrangement being such that the liner, together with its contents, may be quickly and easily removed.

An important feature of the invention resides in the specific construction of the liner which prevents it from adhering or, under winter conditions, freezing to the bottom of the can, while another feature of the invention resides in the provision of handles on the liner, which greatly facilitates its removal and handling.

Some of the advantages of the invention lie in its simplicity of construction, in its convenient and expeditious use, and its adaptability to very economical manufacture.

With the above more important objects and features in view and such other objects and features as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure 1 is an elevational view of a garbage can having a liner positioned therein;

Figure 2 is a vertical sectional view, taken substantially in the plane of the line 2-2 in Figure 1;

Figure 3 is a fragmentary sectional detail, taken substantially in the plane of the line 3--3 in Figure 2;

Figure 4 is a fragmentary sectional detail, taken substantially in the plane of the line 4-4 in Figure 2;

Figure 5 is a fragmentary sectional detail, similar to that shown in Figure 4, but illustrating a slightly modified embodiment of the in-. vention, and

Figure 6 is a fragmentary sectional view, taken substantially in the plane of the line 66 in Figure 2.

Like characters of reference are employed to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, the general reference character ill designates a conventional garbage can, having a bottom i 2, a side wall i 4 and a removable cover Hi, the invention residing in the provision of a disposable liner for the garbage can, the liner being designated generally by the reference character IS.

The liner I8 has a side wall 20 of corrugated cardboard material including an inner layer 22 and an undulated outer layer 24 as is best shown in Figure 6, and the upper edge of the side wall 213 is provided with an annular reinforcing band 26 which is of an inverted, substantially U- shaped cross-section, so that it embraces, both from the inside and from the outside, the two layers 22, 2d of the corrugated side wall. The band 26 is secured to the side wall 20 by a plurality of staples 28, and it should be noted that the band 26 as well as the side wall 20 are spaced from the side wall M of the garbage can It to prevent any possible sticking or adhesion.

As is clearly shown in Figure 5, the lower edge of the side wall 20 is provided with a series of undulations 30 affording a series of spaced points 32 for sustaining the entire liner on the bottom I2 of the garbage can, and the actual bottom 34 of the liner is spaced above the lower edge of the side wall 20 and is provided with an upturned, annular flange 36 which is secured to the side wall 20 by a plurality of staples 38. In this manner the bottom of the liner is spaced above the bottom of the garbage can and the spaced points of contact 32 assure that the liner may be readily removed without sticking or freezing to the bottom of the can.

If desired, an annular seat 40 of a substantially U-shaped cross-section may be removably positioned on the bottom l2 of the garbage can and the undulated, lower edge portions 30, 32 of the side wall 20 of the liner may be removably inserted and seated in the seat All as shown in Figure 4, this arrangement being such as to permit the liner to be removed while the seat 40 itself remains on the bottom of the garbage can, when so desired.

Finally, it is to be noted that to facilitate convenient lifting and handling of the liner, the inner wall portion of the reinforcing band 26 is formed with elongated openings 42 while the layers 22, 24 of the side wall 20 are formed with registering openings 44, 46 respectively (see Figure 3). Moreover, the outer wall portion of the reinforcing band 26 is provided with tabs 48 which are struck out or slit on both sides and bottom edges. The tabs 48 are in register with the openings 42, M, 45 and may be bent inwardly as indicated by the dotted lines 5!! in Figure 3 whereby to afiord finger holds for lifting and handling the liner.

It is believed that the advantages and use of the invention will be clearly understood from the foregoing disclosure and accordingly, further description thereof at this point is deemed unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the claimed as new is:

1. The combination of a garbage can including a side wall and a bottom, an annular seat removably positioned on said bottom, said seat having a channel-shaped cross-section Open at the top thereof and afiording an annular keeper groove, and a disposable liner removably positioned in said can and including a side wall and a bottom secured to the last mentioned side wall above the lower edge of the latter whereby the invention, what is lower edge portion of the liner side wall affords 4 wall and having inner and outer rim members at the respective inner and outer surfaces of the lateral wall, said inner rim member being provided with a horizontally elongated opening coextensive with the first-mentioned opening, said outer rim member being provided with a substantially U-shaped slit in register with the side and bottom edges of said first-mentioned opening, a portion of said outer rim defined by said slit constituting a bendable tab adapted to extend into the liner and abut said lateral wall and said inner rim member at the upper edges of the respective openings therein.
