Definitions

• Fluid product distribution member and distributor comprising such a member
• the present invention relates to a fluid dispenser member, such as a pump or a valve, intended to be mounted on or associated with a tank neck.
• the present invention also relates to a dispenser comprising such a dispensing member.
• This invention applies particularly but not exclusively, to the fields of cosmetics, perfumery and pharmacy.
• the dispensing member can be fixed to a tank neck in various ways.
• the fixing can be done by screwing, crimping or even by snap-fastening.
• This attachment usually implements an attachment skirt capable of securing the dispensing member to the reservoir.
• this fixing can also be done by fixing means directly formed by the dispensing member.
• the attachment means generally comprise one or more attachment profile (s), which allow the latching or screwing of the skirt on or 4ans the neck of the tank.
• a problem associated with such a method of attachment lies in the assembly of the dispensing member around the neck of the reservoir. In fact, during such an assembly, the dispensing member must be prepositioned perfectly in the axis of the neck of the reservoir before fitting or screwing onto said neck to avoid any incorrect positioning of said dispensing member. Indeed, a tilted prepositioning of the dispensing member can cause sealing problems and can even in some cases cause the dispensing member and / or the reservoir to break.
• the dispensing member includes a body internally defining a fluid chamber. This body extends into the fixing skirt, projecting widely downwards. At its lower end, the body forms a fluid inlet into the chamber. This entry can be provided with a dip tube.
• the body at the level of the skirt, has a relatively large diameter. However, the body, at this level, is inserted into the neck of the tank once the skirt is fixed on the neck. Since the body extends below the skirt, the body is used to guide the skirt when it is mounted on the collar.
• the introduction of the body into the collar makes it possible to preposition the skirt on the collar. Because it has a relatively large diameter compared to the internal diameter of the neck, the body alone ensures the maintenance in the axis of the skirt relative to the neck. The body therefore fulfills a role of centering or guide for the prepositioning of the skirt on the collar, before its final assembly.
• the object of the present invention is to dispense with the function of guiding or prepositioning the body in the neck while guaranteeing the axial prepositioning centered on the skirt on the neck. This is particularly useful when the body of the dispensing member does not extend into the skirt or the collar. To achieve this object, the present invention provides a fluid dispenser member which does not reproduce the aforementioned drawbacks.
• the present invention aims to provide a dispensing member that is easy to preposition and position on a reservoir.
• the present invention also aims to provide a distribution member and a distributor that is simple and inexpensive to manufacture and assemble.
• the present invention provides a fluid dispenser member intended to be mounted on a tank neck, said member comprising fixing means for fixing the member on the tank neck, said fixing means comprising a peripheral skirt intended to extend around the tank neck, said skirt comprising at least one attachment profile intended to come into engagement with the neck, characterized in that the skirt further comprises a guide section intended to come into engagement around the neck while said at least one attachment profile is not yet engaged with the collar.
• This guide section which can be in the form of an extension of the skirt downwards under the fixing means of the dispensing member, thus ensures a straight and stable axial prepositioning of the dispensing member on the tank neck.
• the guide section will ensure that the axis of the dispensing member is substantially or perfectly coincident with the axis of the reservoir. Therefore, the dispensing member will be more easily brought into position on the neck and the risk of breakage of the reservoir or of the skirt, following incorrect prepositioning of the dispensing member, will be avoided.
• This guide section makes it possible to dispense with the body of the dispensing member.
• the skirt extends downwards from a support wall intended to come to bear on the neck, the skirt thus defining a free end, said guide section extending from said fiber end up to 'to the attachment profile.
• the fixing means comprise a sealing sleeve intended to come into sealing contact with an internal wall of the neck.
• the sleeve extends downward from a bearing wall intended to come to bear on the neck, the sleeve thus defining a free end which extends substantially at the same level as the free end of the skirt.
• the dispensing member comprises a fluid product chamber body provided with a fluid product inlet through which fluid product stored in the reservoir can be extracted, said inlet being disposed at an axial level situated on the height of the skirt.
• the dispensing member comprises a fluid product chamber body provided with a fluid product inlet through which fluid product is brought into the chamber body, said inlet being disposed at an axial level situated above the support wall.
• This location of the inlet of the chamber body thus makes it possible to ensure that the inlet of the chamber body, or even the chamber body itself, is not disposed in the opening of the neck of the reservoir, but above.
• the reservoir often being made of transparent material, such as glass or plastic, this characteristic has the advantage that the entry of the chamber body and the chamber body cannot be seen from the outside through the reservoir. .
• the chamber body is produced in a single piece with the fixing means.
• the inlet is provided with a dip tube intended to extend into the tank.
• the present invention also provides a fluid dispenser comprising a fluid reservoir having a neck and a dispensing member.

• the inlet 230 is advantageously arranged at an axial level situated above the support wall 2061.
• a piston 3 is also provided. The production of this piston is not the subject of the invention and will therefore not be explained in detail.
• the piston 3 forms a main piston 32, a differential piston 31.
• the piston 3 and the chamber body together delimit a space forming a pump chamber 4.
• the piston 3 is advantageously slidably mounted in the body of chamber and allows the main piston 32 to slide tightly in a barrel 22. This sliding of the piston thus makes it possible to selectively decrease and increase the volume of said chamber 4.
• the piston also defines a valve stem 30 which serves as a movable member inlet valve by cooperation with a valve seat of the sleeve 23 thus allowing the selective entry of fluid.
