A sealing vent for a foaming dispenser associated with a squeeze foaming container is described. The vent has an annular structure, with a central aperture encased by a multi-tiered disc section connected to inner facing of a thickened, axial wall. An upward angled, outer flange is connected on an outer facing of the axial wall, and the outer flange is attached at a lower elevation along the axial wall in comparison to the disc section.

The invention concerns a device (1) for dispensing a fluid (L), comprising a supporting structure (2) provided with means (3) for coupling it with a container (C) holding the fluid (L) and comprising: an outlet duct (63) for the fluid (L); a collapsible chamber (60); first valve means (25) suited to control the passage of the fluid; air refilling valve means. The air refilling valve means comprise a flexible portion (15) of an edge (14) belonging to a first element (10) of the device (1), suited to assume a closed position and an open position. The invention concerns also a system comprising a container and a device made as described above.

A liquid supply for an electronic smoking device has a liquid reservoir (110) within a housing (100) for holding a liquid. A buffering channel (120) within or on the housing (100) connects into the liquid reservoir (110) via a port (130). A sealing member (140) is fitted within the buffering channel (120) and provides a movable or slidable seal in the buffering channel (120). Upon expansion of a gas within the liquid reservoir (110) and/or a gaseous component within the liquid, the sealing member (140) moves within the buffering channel (120) to increase the effective volume of the liquid reservoir (110) and compensate for the change in pressure. Over-pressure and under-pressure conditions in the liquid reservoir are reduced or avoided.

A dispenser and applicator head (3) for associating with a dispenser unit (2), such as a pump, the head, having a connection stub (4t) for connecting to the dispenser unit (2); an assembly core (4n) connected to the connection stub (4t); a fluid applicator pad (5) mounted on the assembly core (4n) for coming into contact with a target surface; and a dispenser channel (Ca, Cs) that passes through the connection stub (4t) and the assembly core (4) and that forms a dispenser orifice (50). The dispenser channel (Ca, Cs) includes an outlet segment (Cs) formed jointly by the assembly core (4n) and by the fluid applicator pad (5).

The present invention relates to a dispensing device, comprising: a connecting member to be mounted on the opening of a container, a piston, a cylinder body in which the piston is arranged so as to define a metering chamber between the piston and the cylinder body, the piston comprising a dosing inlet and a dispensing opening, the cylinder body being slidable along the piston, an inlet check valve provided to open the dosing inlet when subjected to negative pressure, an outlet check valve provided to open the dispensing opening when subjected to positive pressure.

The outlet check valve comprises a membrane with a sealing lip adapted to slide against the inner axial surface of the cylinder body.

A wound irrigation device including a container with an opening along the outer surface of the container and a nozzle assembly coupled to the container and configured to selectively allow the liquid to exit the container when pressure is applied to the container.

A soap dispenser including a rigid cartridge, an inverted dispensing pump, a collar carrying a lever for actuating the pump, and a venting system for equalizing air pressure in the rigid cartridge. The rigid cartridge and collar cooperate to removably attach the soap dispenser to a wall-mounted bracket, in which at least the rigid cartridge is disposable being made of recyclable and/or biodegradable material.

A device for dispensing a fluid, including a pocket whose interior volume is delimited by a deformable wall; a pressing surface; a dispensing part including a dispensing cavity; an outlet; a dispensing orifice connecting the pocket to the dispensing cavity; and a dispensing valve located in the dispensing cavity.

A dispenser includes a body having a an exterior surface, an interior surface, a first chamber, a first opening in fluid communication with the first chamber and extending through the body, a second opening in fluid communication with the first chamber and extending through the body, a first valve and a second valve disposed on the body, the valves having a closed and an open configuration, and an actuator disposed at least partially within the first chamber. The actuator may be configured to increase and decrease pressure in the first chamber such that the first valve and the second valve change from their respective closed configurations to their respective open configurations and from their respective open configurations to their respective closed configurations. When in the closed configuration, flow through the valves is impeded.

The invention relates to a device for dispensing a fluid including: a tank arranged so as to contain the fluid; a dispensing pipe arranged so as to guide the fluid in a dispensing direction; a dispensing opening connecting the tank to the dispensing pipe; a dispensing valve which, in an open state, allows fluid to pass from the inside of the tank to the dispensing pipe via the dispensing opening and, in a closed state, does not allow fluid to pass from the inside of the tank to the dispensing pipe; and a return means arranged so as to exert a force on the dispensing valve. Said force moves the dispensing valve from the open state thereof to the closed state thereof. The return means includes a pouch forming a cavity. Said pouch is located in the dispensing pipe. The shape of the pouch is changed via compression when the dispensing valve is in the open state.
