As material is placed in the and distributed. liner, however, the accordion folds will re- Figure 2 is a vertical axial sectional view lax underthe weight of the material, and

the bottom 11 will sink down until finally it rests upon the bottom 32 of the can, the liner being preferably made of a length such as to permit this.

For a number of reasons, among which is the desirability of protecting the inside of the can top 30 rom contact with the material inside, and to insure that the garbage will always be covered in some manner at least, it is preferable to provide a cover 5 of the same material as the liner, and this may be formed as an upward continuation of the same tube. Its height is such that it may be folded in a whorl, as best seen in Figures 1 and 4, so that the edges all meet at the center, each fold 50 of the whorl lying over one and under another. Thus, due to the stiffness of the material, upon pulling aside any portion of the cover 5, the remainder, to some extent at least, will open also, and thus there is provided an opening through which garbage may be drop ed into the can. Upon release of the top 5, owever, the resistance of the material asserts itself and the top refolds and substantially closes the entrance to the can. It is, of course, 'intended that the can cover 30 shall be emplo ed in addition.

uch a cover will revent direct contact between the can and t e contents, and when the can is filled, the liner can be drawn out with the contained garbage, and the entire package dropped as a unit into the collecting truck, and be thus carried away without the necessity of exposure of the contents to the air, and this is particularly made possible because of the employment of the cover member 5 and the employment of the peculiar whorl inter-folding thereof. To aid in closing the top, so that the contents can not spill out when the filled liner has been removed from the can, strings 6 may be provided at the top of the liner. These" d t e top of the liner to can be tied aroun keep its top closed upon removal.

Should 1t be found desirable to employ a hoop at the entrance to the liner-that is, about its upper end-it will be apparent that the same might be associated with the liner in various ways, and the supporting hooks 4 would be attached thereto.

What I claim as my invention is:

1. A can liner of paraflined paper or the like having an inherent resistance to unfolding, comprising an accordion-folded .tube of slightly smaller diameter than the can in connection with which it is to be used so as to be substantially spaced at all times from the walls thereof, a bottom of substantially the diameter of th tube secured thereto entirely about its periphery, means to support the upper end of the tube from the upper part of the can, to leave the tube otherwise unsupported, and stiffening means associated with the bottom to maintain it distended under the weight of material placed thereon.

2. A can liner of paraflined paper or the like having an inherent resistance to unfolding, comprising an accordion-folded tube of slightly smaller diameter than the can in connection with which it is to be used so as to be substantially s aced at all times from the walls thereof, a ottom of substantially the diameter of the tube secured thereto entirely about its periphery, means to support the upper end of the tube from the upper part of the can, to leave the tube otherwise unsupported, stiffening means associated with the bottom to maintain it distended under the weight of material laced thereon, and a top of the same materia comprising an upward continuation of the tube folded in a whorl about the center to close the top of the tube, and by its inherent stiflness tending to remain closed.

v3. In a garbage receptacle in combination with a stifi container, a liner comprising a longitudinally distensible tube of substantially constant transverse area,'and of slightly smaller diameter than the container received within and substantially spaced at all times from the walls of the container, and means for supporting the liner from the upper edge of the receptacle.

4. The combination of claim 3, the tube having a self-closing top closure integral therewith to prevent contact of the container cover with arbage in the tube.

Signed at attle, King County, Washington, this 31st day of December, 1931.
