Fluid substance dispensing device including a dispensing button provided with a hole for tight coupling with a hollow stem of a pump or a valve, and a dispensing opening associated with a shutter that, at least when subjected to fluid substance to be dispensed pressure, translates in contrast to an elastic element freeing the dispensing opening. The shutter having at least one projection cooperating with mechanical opening element associated with the dispensing button. The opening element devoid of fluid substance passages and having a first fixing portion to the dispensing button and a second portion to abut, in use, a fixed part from which the stem extends. At least one elastically deformable part mutually interconnecting the first and second portions. An actuation lever extending from second portion cooperating with the projection to open the shutter when the second portion contacts fixed part consequently deforming elastically deformable part.

A dispensing head for a system for dispensing a product is described herein. The head includes a body having a housing that is provided with an anvil around which a nozzle is mounted. The nozzle includes an outlet orifice to place the housing in communication with the exterior, and wherein the head includes a membrane added around the periphery of the anvil in the housing in such a way as to form between the membrane and the nozzle a path for dispensing the product.

A pump having a piston (1) sliding in a body (3) having a chamber (5) between an inlet valve (11) and an outlet valve (12), an outlet valve element sliding during actuation in the chamber (5), and a passage (40) wherein, at end of actuation, the outlet valve element (39) cooperates in a non-sealing manner with the passage to open the outlet valve. The inlet valve has an inlet valve element (10) that slides after closure in a sleeve (9) with reduced diameter and a spring (20) bearing on the inlet valve element and on a bottom of the sleeve. The spring (20) returns the piston into its rest position. The sleeve (9) has an inner diameter of less than 4.2 mm. The spring (20) has a force of at least 20 N, so that the pump delivers the fluid product at a pressure (P) of at least 15 bars.

A pressurizable fluid container apparatus, system and method of use.

A manually operated pump (1) for dispensing a fluid substance in which the movable element (16) of the delivery valve has an at least partially conical surface adapted to be coupled with a corresponding surface of a seat of the delivery valve, in a manner so as to be fit therein due to the action of the spring (10) that loads the movable element (16).

Priming cap intended to cover, in a closure position, a dispensing head of a device for dispensing fluid product, the dispensing head having an axial end wall provided with a dispensing orifice, the priming cap having a mechanism for trapping fluid in order, in the closure position, to receive and retain fluid that is dispensed through the dispensing orifice during actuations of priming the dispensing device.

Fluid product device having a dispenser joined to a reservoir containing fluid product, the dispenser having a pump body containing a dosing chamber, and a dispensing head with a dispensing aperture, a plunger secured to the dispensing head to slide in the dosing chamber between rest and actuation positions. The dosing chamber has at least two openings, a first opening for filling the dosing chamber and a second opening connecting the dosing chamber to the dispensing aperture. The first opening is made in a cylindrical portion of the pump body in which said plunger slides during actuation, the first opening connecting the dosing chamber to the reservoir when the plunger is in the rest position and isolating the dosing chamber from the reservoir when the plunger moves out of its rest position. The dosing chamber is filled through the first opening when the dispenser is joined to the reservoir.

A reservoir for a nebulizer, and a nebulizer with a reservoir in which, to avoid undesirable rises in pressure, a fluid chamber of the reservoir is pre-collapsed and filled with an initial amount of fluid which is less than the maximum volume of the fluid chamber. Preferably, before being filled, the fluid chamber is compressed and/or expanded by means of gas to a defined volume which is less than the maximum volume of the fluid chamber.

In one general aspect, a flow control valve includes: a housing including a tubular wall surrounding an interior passage, and a flow control section in which the tubular wall includes a conical inner wall surface; a protrusion disposed on an exterior surface of the tubular wall at the flow control section; a sealing member disposed in the housing and configured to be selectively moved to a sealing position in which the sealing member engages the conical inner wall surface to restrict flow of a fluid through the interior passage; and a recess disposed the conical inner wall surface and configured to allow the fluid to flow past the sealing member through the recess when the sealing member is in the sealing position, wherein the recess and the protrusion are radially aligned on the tubular wall.
