Embodiment Construction

[0045] first, figure 1 and 2 The structure of the fixing part F of the present invention is shown in detail. The fixture is shown in these figures in an initial molding position, ie in a configuration at the exit of the mold. The mold (not shown) can be a simple mold with two axially moving shells. Therefore, the demoulding of the fixing part F does not need to be forcibly released, which can ensure the integrity and accuracy of all the protrusions of the fixing part F.

[0046] The fixing part F has a receiving housing F4 in which the distribution part can be received in a fixed manner, in particular by means of a snap-on mechanism. This receiving housing F4 has a central hole F41 through which the actuating rod of the dispensing part passes, see below.

[0047] The fixture F also has a crown F3 extending continuously around the receiving shell F4. This crown F3 internally delimits an annular plate F31 whose function will be given below.

[0048] The fixture F also has ...

Abstract

Fluid product dispenser comprising: - a reservoir (R) provided with a threaded neck (R1) forming at least one external helical thread (R2), - a closure element comprising a threaded skirt (F1) forming at least one internal helical thread (F2), and a band (H) which engages with a clamping action around the threaded skirt (F1), the skirt (F1) comprising a plurality of tabs (F11) each forming a segment (F21) of the internal helical thread (F2), characterized in that: - the fastening member (F) comprises angular indexing means for positioning it with respect to the external helical thread (R2) of the neck (R1) with a predetermined angular orientation, and - the segments (F21) of the internal helical thread (F2) of the threaded skirt (F1) come into corresponding threaded engagement with the external helical thread (R2) of the neck (R1) in the final assembly position.

Description

technical field [0001] The invention relates to a dispenser for fluid products (paste liquids) having a container for a fluid product provided with a threaded neck internally delimiting a hole communicating with the interior of the container. The dispenser also has a dispensing head mounted on the container neck with a dispensing member such as a pump or valve, a button for actuating the dispensing member and a retainer engaging both the threaded neck of the container and the dispensing member. Such dispensers are commonly used in the field of perfumery and cosmetics. In addition, the invention is also applicable to threaded neck cans with screw caps which can be tightened and loosened. Background technique [0002] Typically, the retainer has a rigid skirt internally formed with one or more threads that engage the threaded neck of the container. To place the dispensing head on the container, it is only necessary to screw the fixing of the threaded skirt onto the threaded ...
