Air purge device for an airless liquid product dispenser having a container equipped with means for sampling the product. The device has a bleed ring that has a deformable lip seal accommodated inside a protective part designed to be inserted into the container. The deformation of the lip when mounting the air purge device in the container causes the air to be purged from the container.

Suction device for a liquid product present in a dispenser has a container 6 provided with means for sampling the product 7. The device is developed about a central axis X and has a centralised product suction channel 8 coaxial to the central axis X and having an inlet 14 and an outlet; and annular suction means connected to the inlet 14 of the centralised suction channel 8.

A pump for connecting the inside and the outside of a product vessel for pharmaceutical use including an upstream end for passing a product intended for extending into the vessel and for being in fluid communication with the vessel and, downstream from the upstream end, a check valve switching between configurations for sealing and passing a product. The upstream end is extended upstream by a member forming a passage of a product in a labyrinth, referred to as labyrinth-forming member.

A pump apparatus can include a suction tube, a pliable sealing ring, and an actuator mechanism coupled to the suction tube. The suction tube can be configured to be removably coupled to a container in which the viscous fluid is arranged and be fluidly coupled to an interior of the container and to an output port for outputting the viscous fluid. The pliable sealing ring can be configured to sealingly engage with an interior wall of the container. When the suction tube is coupled to the container and the pliable sealing ring is sealingly engaged with the interior wall of the container, actuating the actuator mechanism can cause the viscous fluid to be suctioned upwardly through the suction tube and output from the output port, ambient air to be drawn into the container, and the pliable sealing ring to move downwardly.

A device for dispensing fluid from a fluid container, the device capable of being set to different discrete and repeatable/equal dispensing amounts, depending on the amount of fluid required to be dispensed by the user for various applications and uses. The device may also be set to an off or closed position to prevent accidental dispensing of fluid when not in use. The device is preferably configured to be affixed to the outer surface of a fluid container, which fluid container is preferably a flexible bag or pouch.

A product dispenser is provided that includes a container within a shell, and a pump and insert for dispensing the product. A spring biases the container and pump away from the tip of the shell. The bottom of the container is pushed up relative to the shell to activate the pump, thereby dispensing the product.

Presented is a liquid fluid dispenser having a container and a large flexible pump head in which air contained within the pump container is used to force the liquid from the pump assemble in the dispensing cycle. The outlet tube is uniform. In one embodiment, a one-way valve extends through the flexible top to enable inflow of air in the recovery phase of the pump cycle. The pump has the advantage of using air as the pumping force medium making it easy to use while the flexible top eliminates the need to prime the dispenser.

The present invention relates to a contents dispensing pump which is coupled to a container (V) for accommodating the contents therein and dispenses the contents, comprising: a pump main body (10); a pump upper body (20); a pump inner body (30); a dispensing valve (40); and an elastic member (50). The pump upper body (20) is coupled to the upper side of the pump main body (10) so that a pumping operation is made by an up and down movement with respect to the pump main body (10). The pump inner body (30) has a bowl shape with the middle thereof formed to be dented so that an inlet valve plate (70) is integrally formed on the lower surface. The dispensing valve (40) is coupled to the upward side of the pump upper body (20), and has, formed therein, a valve protrusion wheel (41) for opening and closing the content outlet (23). The elastic member (50) is positioned between the upper lateral surface extension piece (33) and the lower lateral surface extension piece (34) of the pump inner body (30) so as to draw the pump inner body (30) and simultaneously elastically support the pump main body (10) and the pump upper body (20).

A kit comprising a refill bottle comprising a refill body, a dispensing mechanism and a refill mechanism; a master bottle provided with a liquid reservoir, and comprising a master body, a pump for dispensing the liquid from the reservoir, and a stem fluidly connected to the pump and outwardly protruding from the master body; and an engaging widget configured to allow stable docking of the refill bottle with the master bottle. The stem is positioned within the engaging widget, and the kit is configured to allow a docked refill bottle to be filled with liquid from the reservoir.
