An outlet valve for a dispensing nozzle comprising a first valve component constructed and arranged to be received by the dispensing nozzle and a second valve component constructed and arranged to cooperate with the first valve component. The first valve component and the second valve component define a normally-closed flow interface.

A dispenser for dispensing liquid or pasty materials has a head part with a dispenser opening. The dispenser opening is formed by lip sections which lie directly on top of each other. A lip section for opening the dispenser opening can be lifted from the other lip section by means of a lifting part that engages on the lip section. The lifting part acts on the lip section with a loading direction that runs transversely to a dispensing direction of the material.

DISPENSER DEVICE WITHOUT AIR INTAKE FOR NOZZLES FOR VARIOUS TYPES OF FLEXIBLE PACKAGING, with an outlet chamber (1) that is hermetically controlled by a plug (2), an elastomeric valve (3) and an elastic pad (18); the vertical outlet chamber (1) is defined by a cylindrical capsule (4) and any nozzle (5) together with an internal elastomeric mass (6); the lower capsule (4) has a sealing seat (7) housing the plug (2), which works jointly with an elastic pad (18), so that between it and the lower capsule (4) a passage is formed for the product to be dispensed; the lower capsule (4) and the nozzle (5) are combined with variable parts (8a) and (8b) coupling with the nozzle (9) of any flexible container (10); the plug (2) is housed in the sealing seat (7) with enough clearance to be moved up and down when internal pressure occurs or ceases inside the flexible container (10) and allows the product to pass through the sealing seat (7) or to close it tightly; the elastomeric valve (3) has an elastic opening point (11) designed to open and close when the pressure inside the flexible container is interrupted or present (10).

A spray cap for a spray container includes a tubular wall for connection to the spring container, a cap plate in which a plurality of spray slits is formed and a valve to admit air into the space defined by the wall but which prevents the outflow of liquid from the space to the exterior. The cap plate includes a support plate of polymeric material in which an aperture is formed. An insert of more resilient polymeric material is retained in the aperture and forms a liquid-tight seal with the support plate. The spray slits are formed in the insert. The support plate and the insert define a liquid flow path between the space and the spray slits and include respective opposed annular sealing areas which are situated upstream of the spray slits and are biased into contact with one another by the resilience of the insert. When the spray cap is inverted and an increased pressure is produced in the space the pressure acts on the insert and the insert is thereby caused to deform such that the sealing areas move out of sealing contact and liquid can flow to the spray slits.

A dispensing device for fluid products includes a draw-up pipe, a main body and a dispensing head. The main body includes a pumping system, connected to the draw-up pipe and a fastening ring nut, for fixing the dispensing device to a container for fluid products. The fastening ring nut and the pumping system are mutually coupled for forming between them an air compensation duct which allows the selective passage of air from the outside towards the inside of the container during the operation of the dispensing device. The dispensing head in turn includes a cup, which has in a relative lower portion a passage, and a valve, housed in the lower portion of the cup, configured to adopt a first configuration, or open configuration, wherein the passage is put in fluid communication with the pumping system and a second configuration, or closed configuration, wherein the passage is occluded.

A device for dispensing drops of a liquid or semi-liquid product is provided having an axial tube (12) which has an elastically deformable outer jacket defining an internal space (16) enclosing the product and a neck (14) which defines an open internal passage for the passage of the product. A system for generating drops has an elastic deformable piece (22) mounted inside the neck of the tube around a rigid member (24). The elastically deformable piece has an opening end part (30b) situated outside of the neck and through which the product can exit from the system in case of pressure on the outer jacket. The opening end part (30b) is deformed into a first position when it is mounted to bear on an opening end (36) of the rigid member when no pressure is exerted on the jacket of the tube.

Some embodiments are directed to a valve, including a rigid end piece that defines a center; a rod at the center of the end piece defining an axis; and a flap, wherein the flap is in one piece and has a flexible wall situated opposite a free end of the rod, the flexible wall is perforated by an orifice concentric with the end of the rod, the orifice has a contour substantially homothetic with that of the contour of the end of the rod in a plane perpendicular to the axis of the rod, the orifice has a surface below a projected surface of the end of the rod in the plane, the flap is connected to the end piece by a non-deformable fixed connection, and the flexible wall presses against the end of the rod at any point of its surface in contact with the end.

The present invention relates to a foundation container comprising a pump having convenient pressurization and, more specifically, to a foundation container comprising a pump having convenient pressurization, wherein the outer wall of a pump main body is formed in the shape of an inwardly concave janggu (a Korean traditional hourglass drum), thereby not delimiting a pumping method to vertically pressurizing the center of a pump upper body, but facilitating the discharge of the contents even though any region of the pump upper body is pressurized. In addition, the present invention relates to a foundation container comprising a pump having convenient pressurization, wherein productivity is improved due to easy mass production by integrating a pump upper body and a pump main body in one body and forming a discharge valve and a suction valve in the same shape so as to simplify the structure of a pump.

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).

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.
