- the device 1 comprises: a base element 6 intended to be put in place by means of hooking or adhesion such as clipping or screwing on the container 4 by its lower end 7, a push button 8 provided with a dispensing spout 9 mounted telescopically to the upper part 10 of the base element 6 and capable of acting pumping with respect to the latter, against a return member constituted by - an elastically deformable bellows 11 ensuring the tight connection between on the one hand an inner chamber 12 of the base member 6, open towards the container 4 to allow the passage of the product 2 through an opening 13, and secondly, at its upper end, an internal chamber 14 of the push button 8 in which opens a hole 15 of the dispensing spout 9, associated with opening-closing means, made at the upper end of said bellows 11.
- these means consist of: a first internal peripheral flange 16 made at the upper end of the bellows
- the bellows 11 comprises a base 21 sealingly adapted to the bottom of the inner chamber 12 of the base member 6, and comprises at least one fixed angular indexing means, relative to said base member 6. , and consequently with respect to its locking tab 20 and the push button 8 which itself is movable.
- the indexing means of the bellows consist of at least one radial tooth 22, made on the bottom of the inner chamber 12 of the base member 6, intended to cooperate with a corresponding notch 23 of the base 21 of the bellows 11.
- the base 21 of the bellows 11 has three radial indexing and anti-rotation notches 23 forming between them angles at the center of 120 °, 125 ° and 115 °, fitting on teeth. corresponding 22 of the internal chamber 12.
- indexing is to position a hook 42 in the tube 38 of the base 6, so as to assemble the bellows 11 by indexing the position of the blade 20 of the bellows 11 relative to the stall position. 42 of the base 6.
- the notches 22 and 23, however, would be retained to provide anti-rotation of the bellows 11 relative to the base 6, but could then be identical angles.
- the push button 8 comprises means of indexing with respect to the base element 6, and consequently of the bellows 11 and its locking tab 20 of the spout 9, which are fixed relative to each other. to the basic element 6.
- indexing means are constituted by at least one axial rib 24 formed on the inner wall of the push button 8 intended to cooperate with a corresponding groove 25 of an inner skirt 26 of the base member 6 delimiting its internal chamber 12 on the one hand, and a peripheral housing 27 with the outer wall 28 of said base element 6 on the other hand, which housing 27 is intended to receive the wall of the push button 8 and allow both its axial sliding and its rotation to inside of it.
- the skirt 26 of the base member 6 comprises three grooves 25 intended to cooperate with three corresponding axial ribs 24 of the push button 8, to constitute their indexing means, at angles of 120 ° each .
- the height of the grooves 25 of the skirt 26 is lower, on the one hand, at the height thereof, because of the sectoral recesses 29 which are made on the same side of each groove 25. and, on the other hand, less than the height of the ribs 24 of the push button 8, so as to allow it to slide axially in a certain stroke, in an open position, and thus to pump the product, or to block it in its closed position.
- high position after rotation in the direction of the recesses 29, putting the lower end of the ribs 24 of said push button 8 in abutment against the recesses 29 of the skirt 26.
- the angle at the center of the sectoral recesses 29 is a function of the desired rotary stroke.

- the attachment portion located on the push button does not interfere with the production and demolding of the workpiece downwards.
- this allows to hide the snap portion and to be able to change the rigidity of the clipping by working on the shapes of discontinuous clipping parts.
- the rigidity of the clipping portions 26 can be modulated by positioning a wall 41 connecting the different parts 26 and varying the height of said wall 41.
- This swelling limits the volume located between the flange and the dispensing channel of the flange 16 and the orifice 15 of the dispensing spout 9.
- the product is then distributed normally.
- the bellows 11 is returned to the initial position by its elastic memory effect.
- the depression caused in the bellows 11 due to its return to its initial position brings the flange 16 from a concave position to a convex position.
- This camber variation causes a variation of the volume present in the space between the flange 16 and the orifice 15 of distribution, and thereby a re-aspiration of the product located in this orifice, avoiding the creation of a residue at this level , giving an impression of soiling.
- the device comprises air intake means constituted by at least one vent constituted by: at least one axial groove 32 made on a portion of the thread 33 of the base element 6, to cooperate with a thread 34 of the container 4, at least one radial groove 35 in communication with the axial groove 32 is formed under the wall 36 of the chamber 12 of the base member 6, axial passages 37 made according to generatrices of an axial chimney 38 of the base element 6 immersed in the container 4, said chimney 38 comprising, in its upper part, adjacent to the wall of the chamber 12, three bosses 39 arranged peripherally, defining between them said passages 37, a deformable seal 40 interposed between the base of the neck 3 of the container 4 and the underside 36 of the chamber 12 of the base member 6, having the radial groove 35, leq a seal 40 to an inner diameter substantially equal to that in which the bosses 39 are inscribed, leaving the passages 37 free and an outside diameter such as not to obscure the axial groove 32 of the thread 33 of the base element 6.
- the detrimental effect of using a soft lip is its lack of efficiency to prevent liquid products from leaking through this place.
- the fragility of this type of lip can be damaged by a blow during transportation or assembly for example compromises a good seal.
- the pressure can force the product to pass. through the air intake hole and to infiltrate the periphery of the aforementioned sealing lip.
- the various parts of the system are made of plastics.
- the bellows is made of a plastic material, preferably elastically deformable.
- the constituent material of the bellows has the elasticity of the rubber and is at the same time able to provide, between the two housing elements, the restoring forces necessary for pumping.
- the choice was directed to a plastic material sufficiently flexible to ensure a good seal at the collars, sufficiently nervous to ensure a return to the initial position and ensure a vacuum, and sufficiently resistant to creep to allow to retain the initial tightening and maintain a repeatability of compression stroke and therefore dose.
- the bellows is made of injectable polyurethane.
- Ether-Ester, DRYFLEX Styrene Thermoplastic Styrene-Ethylene-Butadiene-Styrene materials that did not exist about twenty years ago, as well as to some references of polyethylenes made or modified to guarantee a nervousness and an acceptable holding at creep.
- the names are the trade names, in parentheses the chemical names. These materials have all the characteristics listed above.
- a spring (not shown) metal or not, is arranged around the bellows 11.
- a complementary spring can s' prove useful to help this return to the initial position, while maintaining sufficient elasticity at the collars.
