Embodiment Construction

[0022] The following description will be made with reference to a securing element in the form of a cap securing the dosing valve to the neck of the reservoir containing the product and propellant gas, in particular hydrofluoroalkane (HFA) gas. form, but of course the invention is suitable for securing any dispensing mechanism (pump, dosing valve or non-dosing valve) to any fluid product (liquid, powder or paste) with or without push Any type of fixing element (ring or cap) on the neck of the gas reservoir.

[0023] refer to figure 1 , the dispensing device comprises a dispensing mechanism, such as a dose valve 20 , assembled on the neck 31 of the reservoir 30 by means of a fixing element 10 , in particular a crimpable cap. Dosing valve 20 is optional and will therefore not be described in detail below. The dosage valve may in particular comprise a valve body in which the valve slides. The valve body is advantageously fixed into a receiving portion 11 of the fixing element ...

Abstract

A fluid product dispensing device, comprising a dispensing member (20), such as a pump or a valve, mounted on the neck (31) of a container (30) containing a product to be dispensed, with interposition of a neck seal (1) to ensure sealing at said neck (31) of the container (30), said dispensing member (20) being mounted on said neck (31) by means of an attachment element (10), comprising an attachment portion (12) for attaching to said neck (31) of the container (30) and a compression portion (13) for compressing said neck seal (1) against said neck (31) of the container (30), said compression portion (13) comprising at least one protruding profile (17) capable of exerting stresses in said neck seal (1) after assembly, in which, after assembly, said neck (31) of the container (30) generates first stresses in said neck seal (1) and said at least one protruding profile (17); of the attachment element (10) generates second stresses in said neck seal (1), said first stresses being approximately axially opposite said second constraints, said neck (31) of the container comprising an upper edge with a curved shape, said neck (31) defining, at its end, a ridge (32) in contact with said neck seal (1), said at least one protruding profile (17) being disposed radially outside or inside said ridge (32) when the attachment element (10) is assembled on the neck (31) of the container (30), said first and second stresses being approximately axially opposite one another but radially offset, such that said first and second stresses balance at least partially.

Description

technical field [0001] The invention relates to a fluid dispensing device comprising a fastening element for fastening a dispensing mechanism on the neck of a reservoir. More specifically, the present invention relates to a fixing cap for fixing a dosing valve to the neck of a container, a neck gasket being interposed between the dosing valve and the neck to secure a of tightness. Background technique [0002] Typically, a fixing element is used for fixing the pump or valve to the neck of the reservoir. A typical fixing element usually includes a receiving portion for fixedly receiving the dispensing mechanism; a fixing portion for fixing to the neck of the reservoir; Partially secure the neck gasket to compress on the upper edge of the neck of the reservoir to ensure tightness. These typical fixing elements, which may be screwable or snap-on rings or crimpable caps, have certain disadvantages. Especially in the case of dispensers containing propellant gas, the upper edg...
