摘要:
An exhaust valve assembly for a bottle attachment apparatus for handling liquids has a valve housing which forms a valve chamber having an inlet and an outlet, an exhaust valve body disposed on the inlet in the valve chamber, and a safety valve body disposed on the outlet in the valve chamber. The exhaust valve body is biased toward an exhaust valve seat, counter to the flow direction of the liquid and the safety valve body is biased toward a safety valve seat in the flow direction of the liquid. The safety valve seat is integrally molded on the valve housing.

A fluid delivery device includes a pump, a fluid chamber having an inlet and two or more exits wherein each of the exits from the fluid chamber are equidistant from the inlet such that product pumped through the fluid chamber may flow through each of the exits at an equivalent rate.

A valve system for a trigger sprayer including a valve forming an air spring with a portion of the trigger sprayer and being made of a flexible or elastomeric material. The trigger sprayer may include an air-spring valve system wherein the air-spring valve system provides precompression during a pump stroke. The precompression forces developed in the valve system during a pump stroke may originate from an air valve or air pocket trapped between a portion of a valve body and a part of the valve system. For example, a valve may be inserted in a tube retainer which is connected to a valve body of a trigger sprayer. Air trapped in a chamber or space between a portion of the valve and the tube retainer may provide a force against the valve such that a certain force must be applied to the valve before it allows product to be released.

A fluid dispenser head that is adapted to be assembled on a reservoir containing the fluid, so as to dispense the fluid selectively by a dispenser member, such as a pump or a valve, that is actuated by the dispenser head. The dispenser head includes a dispenser orifice, the dispenser head including a film that incorporates bactericidal and/or bacteriostatic agents, and the film being arranged in the proximity of the dispenser orifice.

A discharge device for media has a housing (10), an operating member (88) manually movable relative to the housing (10) and which, for performing a discharge can be transferred from an unoperated starting position in the direction of an operating direction (1a) into an operated end position and with a locking member (52), which is displaceable relative to the housing (10) between a locked position where it prevents the displacement of the operating member (88) into the end position and a release position in which it permits the displacement of the operating member (88) into the end position.

A nasal spray device is an environment friendly spray device so as to spray the liquid medicine in the container from the outlet. The nasal spray device includes a push member, a mount, a rod, a block, a resilient member and a cylindrical body. The resilient member made by metal is received in the cylindrical body so that it does not contact the liquid medicine which is prevented from being spoiled. The cylindrical body does not have any bead received therein so as to reduce the number of parts.

Bellow actuated pump devices for dispensing a product from a container may include a bellow and a base or a bellow, a base, and a valve having two or more valves wherein actuation of the bellow opens a discharge portion of the valve and dispenses a product and the de-actuation of the bellow opens an intake portion of the valve and refills the pump for the next actuation.

摘要:
A device (1) for dispensing, especially atomizing, a preferably cosmetic liquid, is proposed. The dispensing head (4) which can be manually depressed for dispensing of the liquid can be turned to set the dispensing direction. In order to ensure simple and reliable handling, the device has a catch means so that the dispensing head can be turned with catching.
摘要:
A pre-compression pump (10) dispenses microdoses of fluid (F). The pump minimizes pulsing due to pressure fluctuations. The pump is provided with the following to limit pulsing: a low force slow return velocity return spring (46); enlarged fluid passage (58); elastic bumper (74); and, a rachet tooth (76) bearing against the stem (44). Further, a deflectable diaphragm (90), a splined (70) stem (44), no dip tube, and an off-center, gravitational low-point pump inlet (62) assist in printing the pump. The pump includes a stem (44) with deflectable fingers (92) to ensure sufficient momentum in pump operation. Detents (118) and grooves (120) selectively lock a nozzle cap (14) in an inoperative position. To ensure cleanliness, nozzle (60) cleaning is provided, wiping of the nozzle to remove meniscus (M) therefrom, cuts (104) formed in a shroud (98) assist in drawing excess fluid from the nozzle, and an empty volume (108) for collecting fluid run-off from the nozzle. A handle (H) is mounted to the pump providing a grip.
