5 Claims, 4 Drawing Figures PATENTED AUG 15 1912 INVENTOR G O ran Emil Lagsr5m DISPOSABLE BAG FOR USE WITH INCINERATOR-TYPE DRY CLOSETS The present invention relates to disposable bags for use with incinerator-type dry closets which comprise a toilet basin, a source of combustion positioned beneath the bottom opening of the toilet basin and an ash box for collecting combusted waste, the disposable bags being arranged inside the toilet basin in snug contact with the interior surfaces thereof and the bottom of the bag at least substantially covering the bottom opening of the basin.
It is previously known to use readily combustible disposable bags in incinerator-type dry closets for the purpose of collecting human effluent, thereby preventing soiling of the toilet basin and other closet appurtenances.
The effectiveness of these bags is impaired, however, by the fact that they are unable to retain urine and other low-viscosity fluids sufficiently long enough for such fluids to be brought into intimate contact with the source of combustion. This is especially true for modern closets of the type referred to in which the combustion means is in the form of an electrically heated coil for example.
One object of the present invention is therefore to provide a means whereby low-viscosity human excrement such as urine can be collected and retained so that it can be brought into intimate contact with the source of combustion.
A further object of the present invention is to provide means whereby the presence of obnoxious fumes eminating from the toilet is substantially reduced.
These objects are realized by means of the present invention, which is mainly characterized by the fact that an encapsulated layer of saw dust, wood shavings or other finely-divided wood material is placed at the bottom of the disposable bag. The finely-divided wood material serves to reduce the evaporation velocity of the liquid excrement and supplements the ordinary source of heat of the closet and increases the temperature in the combustion chamber. Furthermore, the acids in the wood decompose the urine substances and also, when exhaust gases containing active carbon are produced, bond together certain ill smelling gas molecules eminating from the urine and feces.
' In accordance with one embodiment of the invention, a layer of saw dust is strewn in the bag, which can be effected by pouring saw dust from a container located outside the closet.
In accordance with a referred embodiment of the invention, the saw dust layer is encapsulated, for example, in a separate, prefabricated package, wrapped in a readily combustible material, such as paper.
In accordance with another embodiment of the invention, the layer of saw dust can be fixed in relation to the bag.
This latter embodiment can be realized in ac cordance with the invention by retaining the layer of saw dust in position in the bottom of the bag by means of an extra or false bottom, which is attached to the inner walls of the bag by means, for example, of an external flange.
The invention will now be described in more detail with reference to a number of embodiments thereof diagrammatically illustrated in the accompanying drawing, further characteristic features of the invention being described in connection therewith.
cording to the invention, in the bottom of which bag is placed a separate package of saw dust within a suitable material.
FIG. 4 illustrates in front view a store of disposable bags according to the invention arranged in nesting relationship, which store is suitably positioned, for example, on a wall adjacent the closet.
FIG. 1 illustrates diagrammatically and in front view encapsulated an essentially conventional incinerator-type dry closet,
in which internal elements are indicated by dotted lines, showing the outer casing 10 of the toilet and a toilet seat 11 and cover. FIG. 1 also shows the toilet basin 12, which extends down into the casing 10 and beneath which is arranged a source of combustion l3, e.g., an electric resistance in a form of a grid. Situated beneath the source of combustion 13 is a withdrawable ash box 14. Gases are conducted from the combustion chamber of the toilet through a passage or chimney 15. As will be seen from the Figure, the inside of the toilet basin is covered with a disposable bag 16, in the bottom of which there is placed a layer 17 of saw dust or some other finely-divided wood material, which is intended to absorb and distribute moisture such as urine, to prevent the liquid from running directly through or down onto the combustion source 13 and to supplement the source of combustion when burning and evaporating feces and liquid effluent.
FIG. 2 illustrates an embodiment of the bag 16 illustrated in FIG. 1, in a perspective view, partly in vertical section. In FIG. 2, the reference numeral 18 indicates a substantially conical bag suitably made of paper, and which is provided with a number of folds 19 extending peripherally around the bag and extending from the top thereof to the bottom 20. The folds 19 in addition to enabling the bags to be formed from a strip of material of uniform width also serve to strengthen the bag and to form waste gas passages or ducts therein. Arranged above the bottom 20 is a relatively thick layer 21 of saw dust, wood shavings or the like, and to maintain this layer uniformly distributed over said bottom and in position in the bag the said layer 21 is covered with an extra bottom 22, for example made of paper or some other readily combustible material, and which is attached as by gluing to the inside of the disposable bag by means of an upwardly directed flange 23.
It is not necessary that the layer of saw dust or wood shavings is fixed in relation to the actual bag, since it is often possible to the same advantage to arrange a suitable layer of saw dust etc. on the bottom of the bag from a supply situated adjacent the closet. FIG. 3 illustrates in vertical section a slightly modified arrangement of the invention, the Figure showing the bag 16 and its bottom 20. In the illustrated embodiment, a prefabricated package 24 of saw dust, wood shavings or the like is freely placed on the bottom 20 of the bag, said package being wrapped in a casing 25 of combustible material, suitably paper.
Since it is often desirable to stack a large number of disposable bags in a storage room, the embodiment illustrated in FIG. 3 is often to be preferred, wherewith a number of bags 16 can be nested or stacked in superposed relationship in a cupboard 26 or on suitable shelves. A supply of insert packages 24 are placed in superposed relationship adjacent the stack of bags.
Before using the toilet illustrated in FIG. 1, the toilet seat and cover are lifted and a disposable bag is removed from the store 26 and placed in the toilet basin in a manner whereby the walls of the bag fit closely against the inner wall of the toilet basin. A package 24 is taken from the supply 26 and placed on the bottom of the bag 16, whereafter the toilet seat is lowered and the closet is ready for use.
Although there are many conceivable materials for absorbing and distributing liquid efiluent and for counteracting obnoxious gases eminating from the toilet, waste material from the timber industry, and in particular saw dust, wood shavings and similar material, has been found to possess advantageous and surprising properties. These materials have the ability of rapidly absorbing moisture, particularly urine, and distributing the liquid throughout the bottom layer in the disposable bag, so that the liquid does not run in concentrated flows down onto the combustion source or through the same. Furthermore, the use of such material provides a combustible material which supplements the combustion source when burning the waste. Moreover, the urine is evaporated in an advantageous manner, since the finely-divided wood material, both in a natural and carbonized state, is able to decompose and bind ill smelling molecules and prevent obnoxious gases from pervading the surroundings.
The invention is not restricted to the shown and described embodiment, but can bewidely varied within the scope of the following claims.
What we claim is:
l. A disposable bag for incinerator-type dry closets, the bag being placed within the toilet basin of the closet with its side walls in contact with said toilet basin and with the bottom thereof at least substantially covering the lower opening of the toilet basin, characterized in that the bag has arranged in the bottom thereof a separate encapsulated bottom layer of finely-divided wood material, the finely-divided wood material being encapsulated in a liquid permeable material.
2. A disposable bag according to claim 1, characterized in that the encapsulated bottom layer covers substantially the whole of the bottom of the bag.
