United States Patent O 3,495,762 DISPOSABLE BAG FOR IN CINERATOR ASHES AND THE LIKE Frank A. Verbic, 25114 Hazelmere Road, Beachwood, Ohio 44122 Filed .lune 3, 1968, Ser. No. 733,962 Int. Cl. B65d 33/00 U.S. 'CL 229-53 1 Claim ABSTRACT F THE DISCLOSURE BACKGROUND OF THE INVENTION The present invention relates to a non-combustible disposable article which has utility for use in incinerators, cooking lbroilers, coal burning stoves, and the like.

Taking incinerators as an example, there has heretofore been a problem, not so much in the larger (coml mercial) installations, where an Archimedes screw may suice, but in small home incinerators in removing and/ or disposing of solid products of combustion (e.g., dusty ashes) from a rigid bottom receptacle, such `as a drawer. Similar problems exist when trying to use a rag, shovel, broom or other tool to dispose of grease at the bottom of a broiler, or ashes in a small coal or Wood burning furnace, stove or fireplace.

An object of the present invention is to provide simple an inexpensive means for overcoming the above mentioned difliculties.

BRIEF DESCRIPTION OF THE DRAWING Other objects and advantages will become apparent and the invention may be better under-stood from consideration of the following description taken in connection with the accompanying drawing, in which FIG. 1 is a perspective view of a disposable article according to one aspect of the inveniton and shown in place in a removable drawer-type ash collector of the prior art type used in some incinerators.

FIG. 2 is a detail showing a preferred accordion type pleat construction suggested and claimed for the sides of the disposable article.

FIG. 3 is a perspective view of the disposable article with its pleats (hence sides) extended ready for folding over, to prevent ying dust, etc., when the disposable article is part filled, then removed and placed (e.g., outdoors) for collection.

FIG. 4 is a perspective View of the disposable article collapsed and mounted on a throwaway backing (e.g., for shipping and store display).

DESCRIPTION OF PREFERRED EMBODIMENT Referring to the drawings FIG. 4 shows disposable article 10, attened, as it might be displayed in a store or taken home for eventual use. In FIG. 1, the article is shown having a bottom 10B and msy wall portions which have accordion type side pleats 10S and end pleats 10E. In FIG. 1, the pleats are only part (e.g., 1A) extended, e.g. so that the top of the article 10 is about liush with the top of a prior art ash drawer 11 in which it is placed. FIG. 2 is a detail showing the construction of the pleats at a typical corner, and FIG. 3

lCe

shows the bag or article of the lnvention pulled way up (pleats attened, or nearly so), for folding over the edges and tieing them as with a twine (not shown) for dust free removal and storage for pick-up.

As in the prior art, the drawer 11 may have a front handle or knob 12 to assist in removing it. The bag 10 can be made of any non-combustible material which is suiiciently flexible for the purpose, aluminum foil of several times the gage used for ordinary kitchen wrapping being suitable, as would be lead foil, or tin foil. The article can be made in any suitable manner, e.g. sides might be flat formed integral with a flat bottom, then brought up and surrounded with another layer of sides with or without another layer of bottom formed integral, and may be welded or glued with a high ternperature resistant adhesive or otherwise fastened together, before or after the pleating.

For merchandising and sale the article 10 may be loosely adhered to a flat cardboard 14 (see FIG. 4) and the cardboard may have a hang up hole 15 and/or suitable display advertising, as desired.

A grate is assumed which, according to usual grate dimensions in an incinerator, is considerably smaller than the pleated edges (so that droppings do not compress them) but even if this were not so, as in an open fireplace or broiler, arrangements can readily be made to fold over side and end tops, or added tabs (not shown), over the top of a removable drawer or other rigid structure. In any event when the bag, part compressed (as in FIG. 2) is full, its sides are readily pulled up to greatly increase receptacle size and provide added material to close off the top of the article and effectively prevent loss of ashes, grease or whatever.

There is thus provided a device of the character described capable of meeting the object Iset forth. In use suicient bulk of the refuse material (which is light) will ilow to the bag corners to make it easy to pull up the sides and push or twist them together, and the disposable extensible (e.g., accordion pleated) bag allows ready removal without loss of its noxious contents, and gives advantages of minimizing atmospheric pollution, and of safety, because of closing 01T of spark sources.

Obviously, instead of the upwardly progressing accordion pleats illustrated, other pleats or folds could be used.

I claim:

1. A heat-resistant, flimsy-Walled incinerator bag made of a metal foil and having a bottom wall and upwardly lextending therefrom plural side wall portions which interconnect to define a space open only at the top, each of said side wall portions having means including multiple pleats for defining at least three modes of utility for the bag, said modes being (1) collapsed to a irst and minimal height for shipment, storage or display, (2) extended to a second and intermediate height for receiving refuse, ashes and the like while within an incinerator, and (3) extended to a third and greatest height for bag tie-up and subsequent disposal.
