A foamer for use in dispensing a liquid product with a foam consistency includes a top cap, a closure, a housing, an air-flow diaphragm, a mesh screen and a valve structure. The closure includes a portion which is received by the cap and these two (2) cooperate to define a foam outlet. The housing is assembled into the closure and the diaphragm is assembled into the housing. The mesh insert is positioned adjacent the foam outlet. The valve structure is provided in two (2) embodiments, one being a duckbill valve with a corresponding holder and the other being a metering valve with a corresponding holder.

A system for distributing a fluid product which is packaged in a tank, the system comprises a base and a cap which are intended to be mounted on the tank together forming a distribution chamber which has a supply passage for packaged product, the cap having a wall which is provided with a skirt for assembly on the tank and a sleeve which is arranged around a nozzle of the base forming between the sleeve and the nozzle a distribution interface which opens in a distribution hole formed in the wall, the wall being reversibly deformable by the pressure of the product in the distribution chamber from a stable closed state of the interface in which the sleeve is arranged in sealed contact around the nozzle towards a deformed opening state of the interface in which the sealed contact is broken in order to allow the distribution of the product contained in the distribution chamber through the distribution hole.

A spray device has a spray nozzle unit (1), wherein said spray nozzle unit (1) comprises a cavity (5) with an inlet (2) for receiving a pressurized liquid at an operating pressure and an outlet (3) for releasing a liquid spray during operation. A spray nozzle body (10) is fitted sealingly within said cavity (5), having a perforated nozzle layer (14) with at least one spray orifice (16) that extends between an upstream surface and a down stream surface thereof releasing at least one jet of said liquid spray at said downstream surface of said nozzle layer. The spray nozzle unit (1) is provided with a pressure safety device (30) upstream of said spray nozzle body (10). Said pressure safety device (30) comprises a closed burst layer (34) that closes a fluid pathway between said inlet (2) and said spray nozzle body (10) but ruptures once a threshold pressure is exceeded. Said operating pressure exceeds said threshold pressure.

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 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.

A container includes: a container part adapted to store a material therein and having a discharge part disposed on one side thereof to discharge the material therefrom; and a sliding cap coupled to top of the container part and moving a space between a first position for blocking the discharge part from the outside and a second position for exposing the discharge part to the outside according to external forces applied in different directions, wherein the container part and the sliding cap each have at least one or more magnetic members adapted to fix the sliding cap to the first position or the second position and help the sliding cap move, if the external force greater than a given level is applied to the sliding cap, in a direction to which the external force is applied.

A multiple dose syringe has a first valve defining a first valve opening pressure and a second valve defining a second valve opening pressure. A storage chamber in fluid communication with the second valve stores multiple doses of a substance therein and includes an outlet for dispensing multiple doses of the stored substance therethrough. A compression surface is movable between first and second positions and defines a compression chamber between the compression surface and the first valve. Movement of the compression surface in a direction from the first position toward the second position dispenses substance in the compression chamber through the first valve and out of the syringe. Movement of the compression surface in a direction from the second position toward the first position causes substance to flow from the storage chamber through the second valve and into the compression chamber.

A device for dispensing a fluid substance includes a manually operated pump with a hollow stem movable counter to a spring, the hollow stem coupled with a piston which slides in a sealed manner inside a cup body to define a compression chamber coupled with a first valve element for the inlet of the fluid substance into the compression chamber fluidly coupled with a second valve element for the outlet of the fluid substance from the compression chamber, there being a dispensing button equipped with a dispensing nozzle mounted on the hollow stem, the dispensing button featuring at least one channel for supplying the fluid substance to the nozzle; the nozzle is formed of an essentially rigid body which is secured, in a sealed manner, into a seat in the dispenser button, the rigid body being coupled with a deformable body defining a dispensing port so that during dispensing, the deformable body—at least in the vicinity of the dispensing port—deforms and then returns to its non-deformed configuration thereafter.

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 nozzle chip comprising: a first layer provided with a first layer orifice, and a mechanically flexible nozzle layer provided with a nozzle orifice, wherein the first layer has a valve seat arranged aligned with the nozzle orifice, wherein the spray nozzle chip has a valve functionality obtained by movement of the nozzle layer relative to the valve seat due to pressure changes, and wherein the nozzle layer is arranged at a distance from the valve seat when the nozzle layer is in a default non-pressurised state, whereby a gap with a gap length (L) is formed between the nozzle layer and the valve seat, wherein the gap length (L) is smaller than a dimension of a specific bacterial type, to thereby seal against bacterial ingrowth through the nozzle orifice of the specific bacterial type.
