Embodiment Construction

[0023] In the description below, the terms "top", "bottom", "upper" and "lower" are figure 1 The erect position shown in, and the terms "axial" and "radial" are figure 1 The longitudinal axis B of the valve is shown in.

[0024] figure 1 The shown metering valve of the blocking type comprises a valve body 10 which extends along a longitudinal axis B. As shown in FIG. Inside the valve body 10, the valve 30 is in figure 1 The detent position shown slides between a dispensing position in which the valve 30 is pushed into the valve body 10 .

[0025] The valve is designed to be assembled on a reservoir 1 , which may be a container to be crimped, screwed or snapped, preferably by means of a fixing element 5 , and advantageously inserted with a neck seal 6 . If necessary, a ring 4 can be assembled around the valve body, in particular to reduce the dead volume in the inverted position and to limit the contact of the fluid product with the neck seal. The ring can be of any shape,...

Abstract

The invention relates to a metering valve for dispensing fluid products, comprising: a valve body (10) including a metering chamber (20); a valve (30) in which the valve body (10) is in a stop position with Axial sliding between dispensing positions for selectively dispensing the contents of the metering chamber (20); the valve (30) includes a flange (320) and is connected to the valve body (10) and the valve ( 30) The mating spring (8) is biased toward its stop position, wherein the valve body (10) includes a cylindrical valve body portion (15) with a flange (320) of the valve (30) on the cylindrical valve body portion (15) ) slides between its stop position and the dispensing position, the cylindrical valve body portion (15) includes a plurality of longitudinal ribs (100) in said cylindrical valve body portion (100) Extending at least part of the height of 15), the longitudinal ribs (100) protrude radially inward and act on the flange (320) of the valve (30) to substantially position the flange (320) at At the center of the cylindrical valve body part (15).

Description

technical field [0001] The present invention relates to a metering valve and a fluid dispensing device comprising such a valve. Background technique [0002] So called metering valves, i.e. valves which dispense a precise dose of fluid product with each actuation of the valve, are well known in the art and are usually assembled between a reservoir containing the fluid product and a gas propulsion for achieving dose advancement device. [0003] There are two known types of metering valves. [0004] So-called stop valves include valves which partially close off the metering chamber in the detent position. More precisely, the outside of the valve cooperates in a sealing manner with the chamber seal of the metering chamber, so that in this detent position the metering chamber is only connected to the reservoir via the inner channel of the valve. [0005] So-called non-prime valves (valves sans ) or ACT valves are filled only before actual actuation. [0006] With retard va...
