A liquid dispenser comprises a housing and a hook for suspending the housing from the rim of a lavatory bowl. A user inserts a sealed inverted reservoir bottle into the housing, which breaks the seal. A plate located in the housing conveys liquid from the bottle to a position within the stream of flushing water. The plate can be adjusted to accommodate different lavatories. To allow venting of the bottle, small vent holes are formed in the plate. The plate may have a number of raised holes or elongate slots. A vent system for the bottle is also provided.

Dispensing liquids

An electrode array device for use with a conductive element to simulate a crevice that is subject to corrosive conditions. The device includes a non-conductive member and a plurality of electrodes. The non-conductive member has a face, with the member defining (i) an opening through the member, the opening passing through the face of the member, and (ii) a depression formed in the face and contiguous with at least a portion of the opening. The plurality of electrodes is embedded in the member, with each of the plurality of electrodes having a portion exposed from the member to the depression.

An overcap sprayer assembly and method of its manufacture. The overcap sprayer assembly includes an actuator and an overcap. The actuator has a body and a sprayer arm. The body attaches preferably to the valve cup rim of the can. A skirt extends circumferentially around the perimeter of the body. At least one actuator access port provides access through the skirt to the interior of the body. The sprayer arm of the actuator has a nozzle adapted to direct spray outwardly through an actuator access port. The overcap attaches to the skirt of the actuator body in coaxially turning relation thereto. An overcap wall extends downwardly from the outer margins of the overcap dome, surrounding the actuator body. The overcap also has at least one overcap access port that may be moved between an open position, wherein an overcap access port is aligned with the actuator access port through which the nozzle is adapted to direct spray, and a closed position, wherein the overcap wall obstructs the actuator access port. Preferably a lock member extends from one of the actuator body and the overcap to project into and engage an opposed locking port of the other of the actuator body and overcap. Preferably the locking port is an access port. The lock member has an unlocked position, wherein it is not engaged in an opposed locking port and the overcap may freely turn on the actuator body, and a locked position assumed when the lock member becomes aligned with an opposed locking port, projects thereinto, and engages the opposed locking port, resisting further overcap turning.

Overcap sprayer assembly

An injection molding mechanism and method of its use for the formation in a single sequence of operations of weld-line free cylindrical container body portions having a central opening at one end. The central opening is formed by the removal of the central top sprue portion of the container body. The container body produced by this mechanism can be used as a pressurizable dispensing container.

A fluid control valve which has a deformable valve member with a fluid passageway therethrough. The fluid passageway is closed by a pressure-exerting member. Initial actuation of the valve by pressure on an actuator assembly compresses a spring which moves the pressure-exerting member away from the deformable valve member, thus allowing the fluid passageway to open. The fluid control valve also having a base portion containing a tortuous path air channel. When the base portion is fitted against a neck plug of a reservoir, a vent opening in the neck plug opens into the air channel of the base, allowing air to enter the reservoir while preventing liquid from leaking out of the reservoir should the reservoir be tipped over.

Fluid control valve

A manually operable spray pump with a double-action pump and a detachable fluid reservoir. A pump cylinder has valves at each end to admit air into one of two pump chambers formed by a piston and means to simultaneously force air from the other chamber down a shaft and out over a fluid discharge port, thereby pulling fluid from the reservoir and spraying it from the device.

A piston-powered fluid dispensing system is disclosed. The fluid dispensing system comprises an apertured base, a hollow elongated cylinder, an apertured piston, a hollow orificed overcap, an elongated fluid passageway, an externally-channeled hollow extension, and three valves. The elongated cylinder, which defines a longitudinal axis, carries the base at one end portion and defines a hollow neck at the opposite end portion. The piston, disposed in the cylinder for providing two cylinder chambers, defines a circumferential portion that is slidably engageable with the cylinder substantially along the length of an inner surface. The overcap, carried by the cylinder and rotatable about the longitiudinal axis, defines an internal fluid-mixing region and a throat that is in fluid communication with the fluid-mixing region. The throat, carrying the externally-channeled extension, is slidably engageable with an inner surface portion of the cylinder neck. The extension, also slidably engageable with the inner surface portion of the cylinder neck, carries the fluid passageway and provides fluid communication between the fluid passageway and the fluid-mixing region. At least one external channel of the hollow extension is able to provide fluid communication between one cylinder chamber and the fluid-mixing region. One valve is carried by the base. A second valve, carried by the fluid passageway, abuttingly engages the first valve. A third valve, provided by relative movement between the extension and neck, controllably affects flow between the one of the two cylinder chambers and the fluid-mixing region.

Piston-powered dispensing system

Apparatus for orienting heavy mold bases and the like, including a pair of rockers connected together in spaced align relation and having upper planar support surfaces terminated at one end by a fixed abutment and at the other by an adjustable clamp. The curved surfaces of the rockers have a curvature of shorter radius at points near the abutments than at points near the clamping devices. The curved surface, abutment and clamping device of each rocker are arranged such that the center of gravity of a heavy mold base is normally slightly off-center toward the abutment end of the rockers.
