Abstract: An animal litter container has a receptacle containing a lower layer of moisture-absorbent material covered by a liquid-permeable upper layer of particulate material which is relatively moisture-impervious. The lower layer may be segregated from the upper layer by a liquid-permeable barrier effective to reduce the emanation of odors from the lower layer.

Abstract: An insertion device for a diaphragm is provided. The device comprises an elongated hollow member which has a chamber for longitudinally holding a diaphragm. An opening is provided in one end of the member through which the diaphragm is dispensed. A plunger means slidable within the hollow member is at the other end of the member and used for dispensing the diaphragm through the opening. An indicia means is provided on the plunger for indicating the proper orientation of the diaphragm for insertion. The chamber preferably contains a disposable diaphragm and a spermacidal agent. An indicia means may also be provided for indicating the complete release of the diaphragm from the opening. A removable closure means, e.g. self-sticking tape, may be provided for sealing the opening.
