Abstract: A system for storing biopharmaceutical materials includes a plurality of flexible walls bounding an interior for holding biopharmaceutical materials therein. At least one port is connected to a first wall of the walls and provides fluid communication between the interior and an exterior to allow a draining of the interior. A collapsible conduit includes a plurality of perforations along the conduit. The plurality of perforations is configured to allow flow of the biopharmaceutical materials from the exterior to the interior of the conduit. The conduit has a cross-sectional area transverse to a length of the conduit and the conduit extends from one of the at least one port toward an opposite end of the interior. The conduit is collapsible by the flexible walls and forms a reduced cross-sectional area to allow a flow of the biopharmaceutical materials through and/or along the conduit to the port.

Abstract: A wall mounted dispenser for dispensing a mixture of water and liquid chemicals which may be used as a separate dispenser or in combination with other like dispensers. The dispenser of this invention includes several backflow preventers to ensure that the water supply will not become contaminated during backflow problems.

Abstract: A dosing device for dispensing liquid from a container (1) in which flow through flow openings (23) to an outlet tube (44) is blocked after controlled delay by an obturator (3) moveable within a control chamber (2) mounted in a container neck (101) behind the outlet tube (44). Movement of the obturator (3) is governed by restricted flow through control openings (28) at the rear of the control chamber. Restoration of the obturator to the back of the control chamber facilitates repeated dosing. An elastomeric element (6) of resiliently deformable material promotes a seal to achieve a cleanly defined dose. In one proposal the elastomeric element coats the surface of the obturator and/or the outlet tube (64) to cut off the flow. Another proposal provides a one-way elastomeric valve element (63) for blocking the flow openings to enable rapid recovery after a dosing operation.

Abstract: An oil flow control structure for grease gun has a hollow main body. An inflow end and an outflow end are respectively disposed at two sides of the main body. A high pressure passage and a low pressure passage, in which its inner diameter is larger than the high pressure passage, are disposed between the inflow end and the outflow end. A first pumping rod and a second pumping rod are respectively disposed in the two passages. The first pumping rod is pivoted to a pressing stem. The second pumping rod is pivoted to the pressing stem through a switching mechanism. The switching mechanism can regulate a pivot position of the second pumping rod relative to the pressing stem so that an initial position of the second pumping rod performing piston motion in the low pressure passage can be changed to seal or open the second inflow port.

Abstract: A fluid dispenser device including a pump for dispensing the fluid; a first arm referred to as the “main” arm, mounted to pivot on the device about an axis referred to as the “main” axis, which arm has a press zone on which the user exerts pressure in order to actuate the pump; and a second arm, referred to as the “intermediate” arm, mounted to pivot on the main arm about an axis, referred to as the “intermediate” axis, this axis being disposed on the main arm between the press zone and the main axis, and the intermediate arm being configured to transmit the movement of the press zone to the pump.

Abstract: A device for dispensing liquid contained in a container, the device including an elastomer element that can take up: a liquid release position allowing liquid to flow out of the device; and a non-return position preventing liquid from flowing back into the device; the device further including a bearing mechanism against the elastomer element in register with a recessed zone, serving to deform the elastomer element in its non-return position.

Abstract: A valve operating mechanism for use in a fluid dispenser is described, wherein the fluid dispenser includes a reservoir for a fluid to be delivered, a fluid outlet for the reservoir, a piston configured to move through the reservoir, and an actuator for the piston, the valve operating mechanism including a valve, wherein the valve has an upstream side and a downstream side, and in at least one point of operation of the valve operating mechanism, the valve is inoperable as a consequence of the pressure difference between the upstream side of the valve and the downstream side of the valve.

Abstract: A fluid container includes a housing unit including a free-fluid chamber, a regulated chamber, and a plurality of valves. The free-fluid chamber is configured to store fluid. The regulated chamber includes an air bag assembly, an outlet, and a plurality of states. The air bag assembly is configured to regulate respective fluid therein and includes at least one air bag including an internal chamber having a volume capacity. The outlet is configured to transport the respective fluid from the regulated chamber. At least one of the plurality of valves is configured to selectively stop fluid communication between the regulated chamber and the free-fluid chamber based on the respective state of the regulated chamber.

Abstract: The invention relates to a dispensing device (11) for containers (33) containing a compound, comprising a compartment (12) for the container, with a piston rod (13) that can be moved relative to the compartment (12), with an extruding device (16) that comprises a drive wheel (21) for advancing the piston rod (13), a motor (22) for driving the drive wheel (21) as well as a planetary gear (23) that is interposed between the drive wheel (21) and the motor (22) and that has a gear rotational axis (24) and a ring gear (25). The ring gear (25) is provided with multiple recesses that are located along its circumference at intervals from each other. Moreover, the dispensing device (11) has an actuating switch (31) for actuating the motor (22) and a blocking element (36) that can be moved from a blocking position that blocks the ring gear (25) into a releasing position that releases this ring gear (25).

Abstract: A spray head assembly includes a head, a main tube, a link, a piston, a reception member, a mount piece and a spring. The parts made of metal such as the spring is isolated from the liquid to ensure that the liquid is not affected by the metal. The main tube can be stopped by the extension portion of the mount piece so as to adjust the length of the mount piece to control the travel distance of the main tube so as to control the volume of each spray.

Abstract: An automatic ground-coffee dispenser with a ground-coffee storage vessel designed to be mounted on an automatic coffee maker. The storage vessel includes rotary serving paddles for transferring a predetermined quantity of ground coffee through an outflow opening formed in the bottom of the storage vessel and a cone-shaped driver with rotary paddles located above the outflow opening turned by a motor about a vertical axis of the storage vessel. The internal wall of the storage vessel includes at least one longitudinal rib projecting into the storage vessel.

Abstract: A dispenser for flowable material adapted for engagement and for dispensing fluid from either a replaceable piston pump reservoir unit comprising a reservoir bottle and a piston pump or a replaceable peristaltic pump reservoir unit comprising a reservoir bottle and a deformable tube member.
