Abstract:
A fluid delivery device (100) includes a pump (190), a fluid chamber (129) having an inlet (123) and two or more exits (126) wherein each of the exits (126) from the fluid chamber (129) are equidistant from the inlet (123) such that product pumped through the fluid chamber (129) may flow through each of the exits (126) at an equivalent rate.
Abstract:
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 wherein actuation of the bellow dispenses a product and the de-actuation of the bellow refills the pump for the next actuation.

Abstract:
A fluid material dispensing kit including a pouch, provided with a flexible casing and a dispensing case provided with a cover that is to be mounted onto a base. The cover includes an upper recess that has a manually flexibly deformable wall mounted thereon. The wall has a dispensing opening, and the cover is provided with a lower reinforcement that defines, with the wall, a pumping chamber. The reinforcement has a supply opening. The distribution opening and supply opening are provided with, respectively, an output valve and an input valve. The pouch has, built therein, a coupling provided with a well that is sealably covered by the casing of the pouch, and the reinforcement includes a nipple that is to be placed into the well. The nipple is set up so as to enable the perforation of the casing during the placement thereof into the well.
Abstract:
Improved bellows and bellows and base attachments for pumps facilitate smaller actuation forces for pumps having a base and unitary valve member.
Abstract:
A valve (338) has a body (312, 314) a fluid inlet (378), a fluid outlet (399) and a bore (362) defined in the body and which forms at least part of a fluid passage from the inlet to the outlet. The valve also has a movable valve member (366) with a resiliency flexible diaphragm portion (370) and a valve bore closure portion (374) mounted to the diaphragm for movement therewith. The flexible diaphragm portion (370) is movable in a valve opening direction from an initial resiliently biased configuration (as shown), in which the valve bore closure portion (374) closes the bore (362), to a valve open configuration in which the valve bore closure portion (374) does not close the bore and a fluid flow path through the bore from the inlet to the outlet is established. The valve is configured such that the diaphragm (370) is able to move in the valve opening direction from its initial resiliently biased configuration towards its valve open configuration by a limited amount during which range of movement the valve bore (362) is closed by the valve bore closure portion (374). The valve is particular suited for use as a pre-compression outlet valve for a pump-action dispenser (310).
Abstract:
Fluid dispenser for the discharge of pharmaceutical or cosmetic fluids including a fluid reservoir in which fluid is stored prior to discharge, an outlet channel through which the fluid is dispensed to an environment, and a pump chamber which, starting from an initial state with maximum pump chamber volume, is volumetrically reduced by a manual pump activation. An inlet valve arrangement is provided between the fluid reservoir and the pump chamber, which opens in a pressure regulated manner when a negative pressure exists in the pump chamber with respect to the fluid reservoir, and an outlet valve arrangement is provided between the pump chamber and the discharge opening. The outlet valve arrangement includes a switching valve mechanically compelled to open in reaction to a displacement of an activation handle and independent of the fluid pressure in the pump chamber.
Abstract:
An oral care implement comprises a handle having a container containing oral care fluid, A head includes tooth cleaning elements and a fluid outlet to output fluid into the vicinity thereof. A manually actuatable pump mechanism in the handle between the container and fluid outlet is connected thereto by respective first and second conduits. The pump mechanism comprises a chamber having an inlet connected to the first conduit, an outlet connected to the second conduit, and an actuatable valve mechanism for selectively opening the inlet and outlet respectively to cause fluid flow into and out of the chamber. The mechanism comprises first and second valve elements and a deformable actuator connected to the first and second valve elements. A wall which defines at least a part of the chamber is adapted to be manually moved to operate the valve mechanism.

Abstract:
Improved, rigid valves for pumps include outlet valve portions having a valve seal portion and one or more surfaces which create pockets between the outlet valve and an interior wall of a pump to collect and trap particulates in a formulation being pumped.
