Definitions

• the invention relates to a liquid product dispenser and relates more particularly to the field of miniature sprayers designed to contain a low dose of a luxury product such as for example a perfume.
• a luxury product such as for example a perfume.
• Such sprayers are mainly intended to be distributed free of charge to customers to publicize and appreciate the products they contain.
• a liquid product dispenser is known, for example, a miniature sprayer, comprising a reservoir comprising a mouthpiece and a pump installed in said mouthpiece.
• This pump comprises a pump body in which a piston is mounted, which slides in leaktight manner in the pump body to define with it a liquid metering chamber, an intake valve establishing communication between said metering chamber and the reservoir containing liquid to be sprayed, an exhaust valve establishing communication between said metering chamber and product distribution means and a spring urging said piston towards a predetermined relaxed position, for which said metering chamber is at its maximum volume .
• the assembly between the pump body and the mouth of the reservoir is ensured by the installation of an annular closure piece called “expander", which allows the tightening radially outward of the pump body against the internal wall of the mouth of the bottle and which also serves as an axial stop for the piston, determining the relaxed position (that is to say the rest position, before actuation) of the piston.
• This relaxed position for which the metering chamber is at its maximum volume is stabilized under the stress of said spring.
• the invention aims firstly at the removal of this closure piece forming a stop, called the expander.
• the invention relates to a liquid product dispenser comprising a reservoir comprising a mouthpiece and a pump installed in said mouthpiece, said pump comprising: a pump body in which is mounted a piston, which slides in leaktight manner in the body of pump for defining with it a liquid metering chamber, an intake valve establishing communication between said metering chamber and the reservoir, an exhaust valve establishing communication between said metering chamber and distribution means, a spring urging said piston towards a relaxed position of the latter for which said metering chamber is at its maximum volume, characterized in that said pump body has an outer portion forming a plug ensuring the seal between the pump body and said mouth, and in that said pump body has an annular projection extending inwards, coming e molding, said piston comprising an annular stop cooperating with said annular projection to define said released position, under the bias of said spring.
• said distribution means are arranged in liquid spraying means.
• said annular projection has the shape of a flexible lip.
• it is a lip turned inside the pump body.
• the annular abutment of the piston comprises, on one side, an abutment face cooperating with the lip and, on the other side, a frustoconical portion participating in the inversion of said lip during the positioning of said piston in the pump body.
• said lip can be segmented into several circumferentially adjacent sections.
• All parts of the pump can be molded plastic, except the spring. As will be seen later, this pump has a minimum number of molded parts and all parts are easy to manufacture by molding and in particular easily demouldable.
• the bottle may be glass or, preferably, molded plastic.
• said intake and exhaust valves respectively comprise a plug and a needle defined by a common shutter, movable in axial translation inside the pump body and around which the spring is mounted. This is supported between the pump body and a shoulder of said common shutter. Therefore, the piston is biased under the action of the spring towards said released position, via the common shutter, which tends to keep the exhaust valve closed.
• one end of said obturator forms a frustoconical needle which cooperates with the internal orifice of an evacuation duct formed in the piston, to form said exhaust valve and the other end of said obturator cooperates with a tube of aspiration of said pump body, to form said intake valve.
• the suction tube extends in the extension of the metering chamber and plunges into the liquid contained in said reservoir. It came from molding with said pump body.
• the shutter comprises a plug forming part which is intended to slide in leaktight manner inside the suction tube. At least one longitudinal groove is formed on the surface of said plug, which allows the passage of the product in the intake phase. All the elements are advantageously of circular section and axial symmetry.
• the diameter of the circular contact zone of the interior orifice of the exhaust duct against which the needle comes to bear, is less than the interior diameter of the bore of the suction tube, that is to say the exterior diameter a bushel.
• the shutter has a shoulder for setting the return spring.
• said pump body has an annular upper flange bearing on the edge of the mouth.
• a separable band can be provided at the base of a pusher associated with the piston, this band ensures, before use, the retention of the piston in the low position, which guarantees a better seal of the pump (because the valve admission is closed) but also the inviolability and a better conservation of the product.
• the innermost end of the obturator is shaped like a bell capable of covering an end portion of the suction tube which protrudes from the bottom of the metering chamber and slides tightly along of the outer surface of this end portion. This arrangement allows easier assembly.
• the suction tube can then advantageously include an axial bore of very small diameter favoring priming of the pump by capillary action.

• FIG. 7 is a detail view illustrating a variant of the intake valve
• FIG. 9 is a detail view illustrating an alternative mounting of the pump body on the mouth of the tank.
• FIG. 10 is a detail view similar to Figure 9 further illustrating a variant.
• the sprayer shown comprises a reservoir 1 provided with a mouth 10, in which is enclosed a liquid product such as a perfume.
• the reservoir is cylindrical and the mouth has an internal diameter equal to that of the reservoir.
• this mouthpiece could also have the shape of a more or less narrowed neck.
• a precompression pump comprising a cylindrical-conical pump body 2 is mounted on the tank; said pump body is installed in the mouth. More specifically, the body 2 is fitted with tight radial tightening in the mouth 10 in the manner of a plug.
• the pump body in fact comprises an outer portion 16 forming a stopper which alone ensures the seal between the pump body and said mouthpiece.
• the pump body 2 has an annular upper flange 21 which bears on the rim of the mouth 10, thereby limiting the penetration of the body into the tank 1 and by adjusting the position of the suction tube 22 inside. of this tank, relative to the liquid level.
• the suction tube 22 is a lower extension of the pump body. It came from molding with the pump body itself.
• the pump body 2 contains a cylindrical piston 3 cooperating by means of a return spring 4 with an intake valve 17 and with an exhaust valve 18. It defines with the wall of the pump body a metering chamber 19 .
• the piston 3 carries an external tubular rod 31 extended outwards by an axial evacuation conduit 30.
• the discharge conduit 30 extends the metering chamber outwards.
• the internal volume of the rod 31 is part of the metering chamber.
• the tubular rod 31 is surmounted by a dispensing head 7 forming a push button which carries an ejection orifice 70.
• the rod 31 is extended, in the upper part, by a core 33 delimiting in a complementary manner with the internal wall of the head 7, on the one hand an outlet channel 37 supplied by the evacuation duct 30 and, on the other hand, a vortex spray system 38 into which the channel 37 opens.

• the piston, the tubular rod 31 and the core form only one molded part, made of plastic.
• the vortex system 38 is defined on the internal face of the head 7 by molded recesses, closed in contact with the core. The abutment upward of the core 33 inside the head 7 automatically ensures the tight connection between the conduits, the recesses forming channels of the vortex system and the nozzle, without it being necessary to provide for an indexing of the opposite pieces.
• the head 7 covering the core 33 has a lateral skirt 71 provided, at its lower end, with a detachable peripheral band 6, ensuring its locking in the low position. It should be noted that in this position the intake valve is closed, which greatly improves the tightness of the pump before its first use.
• the strip 6 is separable from the head by being attached to the skirt 71 by a weakening zone 61 capable of being broken or detached by traction. To this end, the strip 6 is provided with a gripping tab 63.
• the strip 6 carries a continuous or discontinuous internal projection 62 which is engaged with the external wall of the tank 1, by hooking in a retaining element.
• the latter is formed of a flange 11 of the reservoir mouth 1 delimited by a reduction in thickness of the wall of the reservoir at the level of the mouth; an annular groove 12 is formed on the body of the reservoir.
• the pump comprises a shutter 5, common to the intake valve 17 and to the exhaust valve 18 since it forms both a plug 51 for the intake valve and a tapered needle 52 for the exhaust valve.
• the common shutter 5 is movable in axial translation inside the pump body 2. It has a shoulder 54 against which the spring 4 bears. The latter is mounted with initial pre-compression between the pump body and this shoulder .
• the pump body 2 is provided with an internal sleeve 24 coaxial delimiting, on the one hand, with the side wall of the pump body, a cylindrical zone in which the piston 3 is guided and, on the other hand, with the obturator 5 a central housing for the spring 4.
• the needle 52 is formed from the frustoconical upper end of the shutter 5. Said needle is biased against the internal orifice of the discharge duct 30. Outside a period of spraying or in the intake phase, the needle 52 is in sealed contact with the internal orifice of the evacuation duct 30.
• the plug 51 is formed, for its part, from the innermost, cylindrical portion of the shutter 5 which is capable of sliding in leaktight manner in the suction tube 22 and more particularly in a short bore 20 defined in the vicinity from the bottom of the dosing chamber.
• a groove 51a is made longitudinally over a sufficient height of the plug to allow, in the intake phase, the passage of the product by suction into the tank 1.
• Another embodiment, not shown, would consist in providing on this same height, a annular necking allowing the passage of the product.
• the height of the shutter 5 and more particularly that of the plug is such that it occupies, in the depressed position of the piston, almost the entire internal volume of the suction tube 22, leaving only a slight clearance, as shown in FIG. 1.
• the head is held in the low position by the band 6 against the return forces of the spring 4.
• the head 7 rises immediately under the effect of the spring 4 and the upward movement of the piston 3, driven by the common shutter, draws the product into the reservoir 1 via the tube 22; the product enters the metering chamber 19.
• the piston 3 has an annular peripheral stop 34 intended to come into contact with an annular projection here having the shape of a lip 23 carried by the upper edge of the pump body 2.
• This annular projection forming a lip has come from molding with the pump body.
• the annular stop 34 cooperates with this lip to define the relaxed position of the piston (and consequently of the push button) under the bias of the spring 4.
• the lip 23 is a deformable lip which can be unfolded outward from the mold release to allow the body to be ejected from the mold during manufacture. It is then folded inwards.
• the lip 23 can be molded substantially in the position which it occupies in FIG. 1, its flexibility being sufficient for the release from the mold to be able to be effected by unfolding it outwards. It then practically returns to its normal position, in particular when the piston is put in place.
• the annular stop 34 has a frustoconical portion 36 participating in the turning of the lip during the final positioning of the piston in the pump body.
• the annular stop has on one side a stop face 35 extending radially cooperating with the lip 23 to define the relaxed position and on the other side said frustoconical portion 36 facilitating or confirming the replacement of the lip mounting.
• the tubular rod 31 which extends between the core and the stop 34 has a diameter greater than the innermost part of the piston which extends between said stop 34 and its free circular edge 40.
• the latter is slightly flared outwards to define a relatively tight contact between the piston and the internal cylindrical wall of the pump body.
• the radial length of the lip 23 is greater than the radial distance separating the internal wall of the pump body 2 and the external wall of the piston, in the vicinity of the lip (i.e. the external wall of said tubular rod 31). Thanks to this arrangement, the innermost part of the piston can be engaged in the central opening of the lip 23 without risk of damage to the end of the piston which must subsequently ensure sealing in operation. Then, after passage of the frustoconical annular stop 34, the lip 23 assumes its final position and the assembly becomes non-removable due to the radial length of the lip.
• the lip 23a can be segmented during molding, that is to say made up of a plurality of circumferentially adjacent portions 60, which facilitates its elastic deformation when the piston is put in place.
• the seal obtained by the contact between the lower end of the piston (the circular internal edge 40) and the inner wall of the pump body 2 is a priori sufficient to avoid any escape of liquid before the first use.
• the embodiment of Figure 1 (piston pressed before the first use) has a reinforced seal due to the fact that the intake valve 17 is closed during the entire period preceding the first use.
• the pump body is devoid of any vent drilling, as shown in FIGS. 1 to 3 and 5.
• the quantity of liquid introduced the filling in the tank is significantly less than the capacity of said tank ( Figure 5).
• the seal is complete but the reintroduction of air is no longer possible.
• the pump can nevertheless remain functional in suction even if a slight vacuum is generated inside the tank, because it is capable of generating a vacuum of 500 mbar, for the example described. An incomplete initial filling improves the situation.
• the maximum vacuum at the end of use will be of the order of 300 mbar and therefore insufficient to prevent the suction of the pump capable of generating a vacuum. of 500 mbar.
• the reservoir has a capacity of 1.5 ml and therefore contains 0.5 ml of product when it is filled to about one third of its capacity. This underfilling is far from being a drawback for the perfumer because it is not in his interest to distribute large volumes of expensive luxury products for free. The perfumer therefore achieves savings both on the quantity of products offered and on the cost price of the sprayer.
• FIG. 6 a vent hole 66 is made in the wall of the pump body and opens into the metering chamber 19 in the immediate vicinity of the edge 40 of the piston when the latter is in the released position.
• the position of the piston before the first use is said relaxed position, as shown, so that the seal is provided at the edge 40 of the piston in sealed contact rubbing with the inner wall of the pump body.
• the vent hole 66 is in communication with the atmosphere, which allows air to be introduced into the tank to cancel the slight depression caused by the previous actuation.
• the setting of the exhaust valve is adjusted by an appropriate choice of materials and dimensions of the contact zone between the needle 52 and the lower orifice 32 of the duct 30, so that it can open once the inlet valve closed.
• the contact zone between the needle 52 and the edge 32 is circular and its diameter is less than the internal diameter of the bore 20 of the body 2, that is to say the diameter of the plug.
• FIG. 7 which essentially represents the bottom of the metering chamber 19
• the suction tube 22 which communicates with this metering chamber protrudes therein and has a reduced thickness in the vicinity of its free end 75, this part which projects into the metering chamber cooperates with the groove plug 51 to constitute the inlet valve 17.
• the fact that the profile of the wall is thinned and more particularly tapered towards its end increases the radial elasticity of the end of the suction tube, which makes it possible to obtain a sliding tightening between the zone of reduced thickness and the plug, suitable for reinforcing the seal with the non-grooved surface of said portion forming a plug and therefore strengthen the tightness of the intake valve.
• the pump body 2a includes an outer skirt 76 enveloping an end portion 77 of said tank 1 which includes said mouth.
• This cylindrical outer skirt extends axially beyond said mouth to constitute a sort of receptacle 78 in which the cylindrical lateral skirt 71 of the head 7 slides.
• latching means 80 are defined between the skirt and said end portion of said tank. This further improves the mounting of the pump body and makes it non-removable. To improve the aesthetic appearance of the assembly, it is preferable that the reservoir 1 and the outer skirt 76 of the pump body be in the extension of one another, axially, without a solution of continuity on the outside. To do this, the wall of said end portion 77 of the tank is thinned to externally define an annular clearance of radial thickness substantially equal to the thickness of said skirt 76.
• FIG. 8 also differs from the previous ones by the structure of the intake valve.
• the end of the suction tube 22 communicating with the metering chamber 19 protrudes therein, while said other end of said shutter 5 is shaped like a bell 81, here with a cylindrical inner wall capable of covering the end portion 82 projecting into the chamber 19 and itself comprising a cylindrical part surmounted by a frustoconical part.
• the diameters are adapted to allow leaktight sliding of the interior wall of the bell along the exterior surface of said end portion.
• the assembly thus constitutes the intake valve.
• This embodiment has several advantages. First, the common shutter is easier to manufacture; it is significantly shorter and the bell is more easily adjusted during assembly. In addition, it offers a larger surface area for opening the exhaust valve and closing the intake valve.
• the suction tube 22 which is no longer traversed longitudinally by a plug has an axial bore 84 of very small diameter, which promotes priming of the pump by capillary action.
• the pump body does not form the receptacle in which the side skirt 71 slides.
• the mounting of the pump body is in accordance with the embodiment of FIG. 1.
• the reservoir 11 is extended beyond the pump body by a tapered wall portion 85, cylindrical, which forms the receptacle in which the lateral skirt 71 of the head 7 slides.
• FIG. 11 there is shown in schematic section, the mold 86 formed of two parts 87, 88 engaged one inside the other to define between them a cavity having the shape of said pump body 2. It is noted that during this molding phase, the part which must constitute the folded lip is molded in the form of a cylindrical crown 89 (possibly segmented) which allows demoulding without any constraints. During a second step shown in FIG. 12, the cylindrical crown 89 is folded back 90 ° using a tool 90, which initiates the formation of the lip 23. Later (FIG.
