A cleaning implement is provided. The cleaning implement includes a liquid delivery system for providing a cleaning liquid to a surface to be cleaned having a canister for storing a liquid, an electrical motor driving a pump, and a voltage source for engerizing the electric motor. A support head is pivotally attached to the handle for releasably receiving a cleaning sheet. The handle includes a switch and is formed from a plurality of handle sections. Each handle section has at least one electrical connector which is electrically connected with an electrical connector of an adjacent handle section so that the switch can activate the electrical motor. The support head can be configured to allow visual inspection of the cleaning sheet through the support head during use. The canister is provided with plurality of side walls and vent valve having a cracking pressure of at least about 0.6 Kpa, wherein the canister is substantially in the form of a parallelogram in a plan view cross section and wherein one or more of the side walls has a plurality of grooves.

A vent and fluid transfer fitment for sealing and transferring a fluid from an inverted fluid-filled container without premature leakage to a receiver attachment, has a transfer check valve and a venting check valve which are preferably duckbill valves. The transfer check valve is attached to the fitment for allowing fluid to be transferred from the container when the receiver attachment engages the transfer check valve. The venting check valve is also attached to the fitment for allowing air to displace the fluid as the fluid exits the container, wherein both the transfer check valve and the venting check valve have an inherent sealing pressure created by the static pressure of the fluid within the container. In addition, the inherent sealing pressure of the venting check valve is less than the inherent sealing pressure of the transfer check valve which allows air to enter the container due to the pressure differential created as the fluid is displaced.

A gear pump and reservoir device for a fluid sprayer comprises a pump housing having a recessed portion for receiving and sealing thereto a fluid reservoir and a cavity for locating a drive motor and gears therein. The recessed portion has a rigid conical projection centered therein which has an orifice extending into a pump inlet. The gear pump further includes a fluid container mounted above the recessed portion of the pump housing to form a fluid reservoir. The fluid reservoir has a discharge valve that is opened by engagement with the conical projection within the recessed portion to provide fluid communication to the pump inlet. A static head in the fluid reservoir maintains the gear pump in a primed state. A fluid line leading from the gear pump to a sprayer head has a discharge check valve located therein. The check valve has a cracking pressure higher than the static head of fluid so that fluid passes to the sprayer head only when the gear pump operates to increase pressure in the fluid line above the cracking pressure. There is also means for powering and operating the motor such that the gear pump provides a continuous flow of fluid to the sprayer head upon demand by a user.

Very slightly thickened, shear-thinning, pseudoplastic liquid detergent compositions are packaged in a non-aerosol spray delivery package specifically configured to produce a minimal amount of visible foam along with a minimal amount of small particles that may cause consumer discomfort and preferably comprise a mixture of nonionic and zwitterionic detergent surfactants; hydrophobic cleaning solvent; and polycarboxylate detergent builder to provide superior cleaning of all of the soils commonly found in the bathroom. The compositions preferably have a pH of from about 1 to about 13, preferably to about 5.5. The compositions are in the form of aqueous liquids.

A cleaning implement has a reservoir, a dispenser and a fluid transfer tube. The reservoir retains a cleaning fluid and preferably is attached to a collapsible handle. The dispenser is attached to the reservoir by a universal joint which comprises a ball and fork configuration. The fluid transfer tube is connected to the reservoir in open communication with the dispenser, wherein the fluid transfer tube is positioned within the ball of the universal joint to prevent the fluid transfer tube from becoming entangled with the universal joint.

A shelf-stable device for transdermally administering an active pharmaceutical to a patient. The device includes a drug reservoir that contains the drug formulation. In one preferred embodiment of the present invention, the drug reservoir is sandwiched between an upper and a lower solvent barrier film that are made from a material such as a polyester that will not absorb the drug and/or skin permeating enhancing solvent, if any, contained within the reservoir. The drug reservoir and solvent barrier films are encapsulated within a hermetically-sealed compartment that protects the drug formulation from common environmental factors such as water vapor, oxygen, and light which can adversely affect the stability and efficacy of the drug formulation. The hermetically-sealed compartment also prevents the drug formulation from coming into contact with and possibly dissolving the adhesive used to secure the device to the patients's skin. In another particularly preferred embodiment of the present invention, the device's drug reservoir is encapsulated within a hermetically-sealed compartment that is made from solvent/environment barrier films that serve the dual functions of preventing the device's components from absorbing the drug/solvent formulation from the reservoir, and protecting the drug/solvent formulation from common environmental factors.

A pump dispenser for fluent products is disclosed as inluding a container for housing the fluent product, dispensing outlet means on the container, a follower piston closing the lower end of the container below the product, and means for varying the volume within such dispenser. The volume varying means comprises a plunger adapted to be reciprocated within the dispenser to alternately decrease the volume therewithin and, following such decrease, return to its original position thereby increasing the volume within the dispenser. The plunger further comprises a peripheral skirt having predetermined outer lateral dimensions at its lower distal end, and an enlarged attachment head on such lower distal end. The attachment head has predetermined outer lateral dimensions which are larger than the outer lateral dimensions of such lower distal end therey effectively forming a reentrant portion on the plunger above the enlarged head. A flexible thin-walled diaphragm adapted to isolate and seal the volume reducing means from the fluent product is connected about its outer periphery to the dispenser. The diaphragm further has a central portion substantially conforming to the enlarged attachment head and reentrant portion of the plunger thereby effectively locking the diaphragm to the plunger and its attachment head. The attached diaphragm is thereby adapted to provide a substantially frictionless seal between the reciprocable plunger and the fluent product. The unique structure and combination of the plunger and flexible diaphragm of the subject pump dispenser provides for ease of manufacturing and handling of such pump dispenser subassembly.
