Definitions

• the present invention relates to a device comprising a base piece and a removable member removably mounted on the base piece.
• the removable member slides in a sealed manner in the base piece on a determined axial stroke.
• the preferred fields of application of the present invention are those of perfumery, cosmetics or even pharmacy.
• the base piece may be integral with a fluid reservoir, and the movable member may be a plug, an applicator or a protective cover.
• WO2013 / 017803 discloses an applicator dispenser comprising a removable member provided with an applicator which is adapted to be removed axially by sliding out of a base piece which comprises a dip tube . More specifically, the removable member is unscrewed from the base piece, which causes its sliding axial displacement: at the end of unscrewing, the removable member can be completely removed and separated from the base piece to be able to put the applicator in contact with a suitable surface, such as the skin. During unscrewing, a depression is formed between the base piece and the removable member, so that the fluid product stored in a tank is sucked through the dip tube to fill the applicator.
• the present invention aims to overcome this drawback of the prior art by defining a device whose removal of the removable member is reproducible reliably and repeatedly, without the user can interfere.
• the present invention can be applied to the dispenser applicator of the type described in WO2013 / 017803, but also to any device in which the removable member is removed by slidable sliding of a base piece.
• the present invention provides an applicator device comprising a base piece and a removable member removably mounted axially on the base piece, the removable member sealingly sliding in the base piece on a determined axial stroke
• the piece base is mounted on a fluid reservoir and comprises a dip tube, a bucket at the bottom of which opens an outlet of a dip tube, the bucket being provided with a piston lip
• the removable member comprises an appendix of gripping, a tubing adapted to slide sealingly against the piston lip on said determined axial stroke and an applicator adapted to retain a dose of fluid produced from the suction plunger generated by the sliding of the tubing against the piston lip on said determined axial stroke
• control means of the type "retractable tip pen” for axially moving the organ removable relative to the base piece by pressing axially on the removable member to the base piece, each axial displacement by pressing on the removable member being followed by a return movement among two kinds of return displacements, namely a small displacement return to the closed position and a large displacement back to the gripping position.
• a retracttable tip pen is meant a type of pen well known for a long time which is characterized by the implementation of a push button, disposed at the opposite end of the tip or the ball, and on which the user can press axially, particularly with the thumb, against a spring housed in the pen, to move the tip (and the reservoir) between two positions, namely an extended position and a position retracted. From the retracted position, actuation of the push button has the effect of pulling the tip of the case from the pen to an extreme stop position. Then, the user can release the pressure on the push button, and the tip will remain in an extended position, in which the user can use the pen to write.
• each axial displacement by pressing the push button is followed by a return movement among two kinds of return movement, namely a small displacement back to the extended position and a large displacement back in retracted position.
• This type of control is here incorporated into the device of the invention by assimilating the removable member to the push button of the retractable tip pen, with however a noticeable difference: indeed, the small displacement in the present invention leads to the closed position , while it leads to the extended position in a retractable tip pen, and the large return movement leads in the present invention to the gripping position, while it drives in a retractable tip pen to the retracted retracted position .
• the advantage obtained by the implementation of this type of control in the present invention lies in the fact that the sliding of the removable member in the base piece on the determined axial stroke is completely independent of the pressing force exerted by the user on the removable organ.
• the extent of the axial displacement and the speed of the removable member are solely dependent on the control means of the pen type retractable tip, and not at all the support force exerted by the user. It should be noted that this advantage is not present in a conventional retractable tip pen, since there is no sliding and tight axial stroke.
• control means comprise:
• an axial guide profile defining low axial abutment housings corresponding to the closed position and high axial abutment housings corresponding to the gripping position, the low axial abutment housings being bordered by inclined segments, the abutment housings; axial axis being formed at the end of respective axial guide stacks and bordered by the inclined segments,
• a thrust sliding ring provided with lugs engaged in two respective axial guide funnels, the thrust sliding ring being provided with a peripheral profile with inclined teeth
• a rotary selection ring comprising inclined-tip axial lugs axially displaced from the low axial abutment housings and the high and rotational axial abutment housings, under the bias of the inclined-tooth peripheral profile and the inclined segments which come into contact; taken with the inclined tips, to move from low axial abutment housings to high thrust bearing housings, and vice versa,
• the large return displacement continues beyond the determined axial stroke, so that the removable member is out of sealing contact with the base piece in the gripping position.
• the entire determined axial stroke is performed during the large return motion conditioned by the spring. The user only has to pick the removable member to apply it on the application surface that suits him.
• the large return displacement is completed below the determined axial stroke, so that the removable member is still in sealing contact with the base member in the gripping position.
• the user will complete the determined axial stroke by pulling on the removable member until it leaves its sealing contact with the base piece.
• the gripping position it is possible for the gripping position to be located at the end of the stroke of the determined axial stroke, so that only a very small portion of the axial stroke is to be made by manually pulling on the removable member .
• the axial guiding profile is formed inside a case in which are housed the thrust sliding ring, the rotary selection ring, the base piece and the removable member in the closed position.
• all the component parts of the device are housed entirely inside the case in the closed position, so that the maximum size of the device corresponds exactly to that of the case.

• the applicator comprises a blind sampling and application space formed in the tubulure, the fluid product being injected into this sampling and blind application space at the outlet of the dip tube. Thanks to the control means of the "retractable tip pen" type, it is ensured that the injection of the fluid product into the sampling and blind application space is always performed identically, both in quantity and in speed, since conditioned by the spring. The user no longer has any influence on this fluid injection step in the sampling space.
• the pipe defines a free lower end which is arranged, in the closed position, away from the bottom of the bucket to allow a small initial axial stroke of the removable member relative to the base piece of in order to bring this lower free end of the bottom of the bucket, before starting said determined axial stroke.
• This small initial axial stroke is indeed necessary to allow the rotary selection ring to disengage housing axial abutment low.
• This small axial stroke is also present in a conventional retractable tip pen: indeed, everyone knows that it is necessary to push the push button fully from the extended position to make it out more, before releasing it for that the tip returns to its retracted position inside the pen.
• the lower free end of the tubing abuts against the bottom of the cup, before starting said determined axial stroke, so that the sampling and blind application space is directly adjacent to the outlet of the dip tube . It is thus also ensured that the entire volume defined between the base piece and the removable member is solely constituted by the blind sampling and application space before the fluid injection phase inside.
