Abstract: A liquid soap dispenser for dispensing repeated doses of liquid soap from an associated cartridge with a compressible outlet nipple without collapsing the side walls of the cartridge, the cartridge includes a blow molded thin walled plastic container with an externally threaded neck for connection to the compressible nipple and a wall. A receptacle is positioned in the wall of the cartridge having an aperture therein, and a plastic filter is in the receptacle having a sealing mechanism connected thereto movable between a sealing position wherein the sealing mechanism seals the aperture and a filtering position wherein the sealing mechanism is away from the aperture and the filter is in contact with the aperture establishing an air path between the inside and outside of the cartridge. The filter having an average pore diameter of about 0.25 microns and is compressed within the receptacle such that upon repeated activation of said pump member the vacuum inside said cartridge does not exceed 12" of water.

Abstract: A system for dispensing liquid soap including a closed wall structure defining a container with a partition separating the container into a separate lower liquid soap reservoir and a separate upper refill compartment. Dispensing mechanism is carried by the container for dispensing liquid soap from the reservoir. The partition has a refill aperture therethrough providing communication for soap flow between said reservoir and the refill compartment and dimensioned to permit the free flow of liquid soap therethrough. A refill cartridge of liquid soap has an outlet, removably enclosed within the refill compartment in a refill configuration with the outlet disposed for cooperation with the refill aperture to permit the free flow of liquid soap from the refill cartridge to the reservoir thereby to refill the reservoir as liquid soap is dispensed therefrom.

Abstract: An air freshener dispenser includes a two-part housing including a base and a separable cover. The base carries a control circuit and the cover carries a dispensing blower and a replaceable cartridge including the freshening agent to be dispensed and a battery for powering the blower. When the cover is removed from the base the blower is connected directly across the battery for test purposes, but when it is mounted on the base, contact structure on the cover and the base cooperate so that the blower is connected to the battery through the control circuit and is controlled thereby. The control circuit turns off the blower and triggers visible and audible alarm signals after a predetermined time period and/or when the battery voltage gets too low. A photocell turns off the blower and disables the audible alarm in the dark. The time-out period of the timer is selectively changeable.

Abstract: A disposable refill cartridge for a liquid soap dispenser having a closed container with a bottom wall portion and a rear wall portion and two opposes side wall portions. An outlet opening is formed in a cylindrical neck extending from the bottom wall portion, as is a frustoconical portion intermediate the bottom wall and the cylindrical neck. At least one boss extends outwardly from the frustoconical portion and the cylindrical neck with two elongated recesses respectively formed in the side wall portions adjacent to the rear wall portion. Each of the recesses extends downwardly to the bottom wall portion, and the container has stepped retaining surfaces at the upper end of the rear wall portion and at the lower ends of the side wall portions. A receptacle is formed in the rear wall having an apertured end wall.

Abstract: A liquid soap dispensing system includes a housing and a discharge mechanism for dispensing repeated doses of liquid soap from an associated cartridge. A receptacle is positioned in the cartridge wall forming an air path between the inside and outside of the cartridge, and a plastic filter is frictionally disposed within the receptacle for permitting air to flow into the cartridge but preventing soap from flowing out of the cartridge. The filter permits sufficient air flow into the cartridge to limit the vacuum therein to not greater than about 12" upon repeated operation of the discharge mechanism to prevent the cartridge walls from distorting.

Abstract: A self-contained air freshening or deodorizing apparatus with a two-part housing including a mounting section for securing the apparatus in an operative position and a closure section for connection thereto for forming an enclosure. A battery-powered air movement generating mechanism includes a fan having a hub with a motor nested at least partially within the hub and connected thereto for rotating the fan hub and five blades mounted thereon to generate a path of air flow through the enclosure. Air freshening or deodorizing mechanism for supplying a source of vaporizable material is positioned in the path of air flow. An antibootleg device is mounted in the enclosure in such a way that removal of the device renders the motor inoperable.

Abstract: A liquid dispenser having a replaceable unvented liquid container with only an outlet opening, a discharge assembly in liquid communication with the liquid container outlet opening, and including a compressible nipple for accommodating a charge of liquid, a check valve for regulating the flow of liquid into the nipple and a semipermeable filter mounted in and substantially filling the inlet to the check valve, the filter element being permeable to air to introduce air into the liquid container through its outlet opening, the filter element being impermeable to liquid to prevent back flow of liquid through the air passageway, and having an opening therethrough which is aligned with the inlet of the check valve, defining a liquid passageway through the filter element to the check valve.

Abstract: A liquid soap dispenser having an unvented liquid soap container with only an outlet opening, a discharge assembly in fluid communication with the soap container outlet opening, and a breathing mechanism including a semipermeable filter mounted between the discharge assembly and the soap container to introduce air into the soap container immediately upon withdrawal of soap from the container to permit rapid operation of the discharge assembly.

Abstract: A battery operated air freshener with a housing having means for mounting the air freshener to a surface such as a wall. A motor inside the housing is electrically connected to a fan and to a battery. A replaceable cartridge with vents defining an air flow path carries a deodorizing substance and a battery. The replaceable cartridge having a receptacle is positioned within the housing such that the battery carried by the cartridge fits between spaced electrical contacts connected to the motor and hence to the fan resulting in air flow through the deodorizing substance. An anti-bootleg device in the housing has at least one prong extending into the cartridge receptacle, whereby a cartridge having an appropriate receptacle to receive the anti-bootleg device fits within the housing such that the battery carried by the cartridge fits between the spaced electrical contacts thereby establishing an electrical circuit to operate the fan.
