Embodiment Construction

[0033] first reference Figure 1a , 1b and 1c, to detail the structure and operation of a fluid application dispenser that can be used as a base dispenser for integration into the present invention. The four embodiments of the invention that will be described hereinafter will only detail the differences relative to the basic administration dispenser.

[0034] The dispenser firstly comprises a fluid reservoir 1 which is only shown very partially. In fact, Figure 1a and 1b Only the upper part of the reservoir 1 is shown forming the neck 11, which is entirely conventional, with external reinforcements for hooking. The fluid reservoir 1 can be of any type and can be made of any material, as the reservoir is not a critical element of the invention.

[0035] In addition to the reservoir 1 , the dispenser comprises two further constituent elements, namely a base element 2 fixedly mounted on the reservoir 1 and a detachable member 3 detachably mounted on the base element 2 .

Abstract

Extraction and application device for extraction and application of a fluid product, comprising: - a base element (2) comprising a dip tube (24) defining the internal volume Vtp of the tube and a piston (27) provided with forming a lip (271 ) cup (21), the lip has a diameter Dp, and a detachable member (3) comprising: a tubular body (33') capable of sealingly sliding against the piston lip (271) and an applicator (35) , the applicator includes an extraction and application space (35), the extraction and application space (35) is formed in the tubular body (33), the fluid product is injected into the extraction and application space through the dip tube (24) and the injection hole (23) In the space (35), it is characterized in that the axial stroke of the seal represents the sliding axial height Hac, and the sliding axial height is determined by the following formula: Hac>4Vtp / π.Dp 2 .

Description

technical field [0001] The invention relates to a device comprising a base element and a detachable member detachably mounted on the base element. The detachable component slides sealingly over a defined axial travel in the base element. Preferred fields of application of the invention are the fields of perfumery, cosmetics or medicine. The base element may be fixedly connected to the fluid reservoir and the movable member may be an applicator. Background technique [0002] In the field of perfumery, known document WO 2013 / 017803 describes an application dispenser comprising a detachable member equipped with an applicator adapted to be axially removed in a sealed sliding manner from a base element comprising A cup, the bottom of the cup is drilled with an injection hole connected to the dip tube. More precisely, the detachable member is unscrewed from the base element, which causes its axial sliding movement: at the end of unscrewing, the detachable member can be complete...
