Definitions

• the present invention relates to a distributor of liquid products and more particularly of liquid pharmaceutical products intended to be dispensed by spraying or by jet.
• dispensers of liquid products of the type comprising in particular a reservoir equipped with means for withdrawing the product such as a valve or a pump on which a dispensing head is mounted.
• sampling means are capable of being actuated by axial displacement of the reservoir relative to a nozzle tube supplied by the sampling means and a part of which projects outside while being capped by said head.
• the doses to be administered correspond to very small volumes of the order of 30 to 50 microliters.
• the product is packaged in tanks made up of bottles of small contents and therefore of reduced dimensions, which makes their use delicate.
• the head covering the nozzle tube then has small dimensions which are not adapted to the numerous manipulations which are nevertheless necessary for obtaining the axial displacement of the nozzle tube.
• the object of the present invention is to solve these technical problems by offering a package whose handling is improved and this independently of the doses of product to be delivered.
• a distributor of the preceding type characterized in that it comprises, on the one hand, a discharge duct connected in leaktight manner to the external part of the nozzle tube and passing through a nozzle rigidly connected to a housing containing the reservoir and, on the other hand, at least one lateral fin engaged with the reservoir or the spray tube and carrying a cam intended to cooperate by sliding contact with at least one inclined wall integral with said tip, so that a thrust substantially radial on said fin results in an axial displacement of the tube relative to the reservoir, causing the delivery of the product.
• the reservoir is removably enclosed in the housing, delimited at its upper part by said nozzle.
• said fin comprises an external flank forming a push button whose generatrices are at least partially parallel to those of the duct.
• said external flank forming a push button extends flush with openings in the side wall of the housing.
• said outer side forming a push button has grooves.
• said end piece extends downwards by a substantially cylindrical skirt provided at its lower part with fixing members on the housing.
• said housing is provided with a set of two diametrically opposite fins.
• the free end of said conduit is provided with a spray nozzle.
• the conduit is connected to said tube by fitting with radial clamping.
• the reservoir is immobilized inside the housing while said fin is integral with the tube and said inclined wall is oriented towards the bottom of the evacuation duct.
• the said evacuation duct is slidably mounted inside the end piece while the reservoir is immobilized in a base possibly fixed removably to the said housing.
• said fin is provided with a connecting arm forming a spacer with said duct.
• said cam is then formed of a boss carried by the inner flank of the fin.
• said fin is integral with the tank which is axially movable inside of the housing while said inclined wall is oriented towards the top of the exhaust duct.
• said discharge conduit is mounted fixed in the end piece while the reservoir slides in a bore internal to the housing.
• said fin is mounted on the neck of the tank by means of a hooking ring.
• said cam is then formed by the lower edge of the outer flank of the fin.
• said inclined walls have contact faces with said cams, the slope of which is variable.
• the dispenser of the invention has a very ergonomic profile and offers flexibility and great comfort of use. It finds a particularly interesting application in the field of spraying cosmetic products such as moisturizers or pharmaceutical products such as nasal solutions.
• This distributor is suitable for both pressure tanks fitted with a valve and atmospheric tanks fitted with pre-compression pumps.
• the radial fins forming the push-buttons ensure easy reliable and sensitive control of the sampling means, which ensures high precision in the distribution of the product.
• the overall aesthetic appearance is very attractive and gives the appearance of a traditional container of the bottle or flask type.
• FIG. 2a and 2b show respectively front and perspective views of the embodiment of Figures la and lb;
• FIGs 3a and 3b show sectional views of a second embodiment of the dispenser of the invention respectively in the rest position and in the dispensing phase.
• the dispenser shown in the figures is intended to deliver successive doses of a liquid product contained in a reservoir.
• the dispenser is traditionally equipped with means for withdrawing the product which consist of either a precompression pump P mounted here on the neck of an atmospheric tank R or a valve (not shown) mounted on a pressure tank.
• sampling means are capable of being actuated by the user who, for this purpose, exerts manual support on a nozzle tube T supplied by said sampling means and one end portion of which projects outside the tank. R possibly being capped by a dispensing head (not shown).
• This support can also be exerted on the bottom of the tank R by the user while keeping the tube T stationary, which in all cases causes a relative axial displacement of the tube T in the direction of the tank R and pressurization of said reservoir.
• the opening of the valve of the pump then allows the product to escape to the outside via the tube T which then returns to its initial position under the action of return means (not shown).
• the external part of the spray tube T is tightly connected to a discharge duct 1.
• the connection is made here by fitting with radial tightening of the tube T in the duct 1.
• the end the lower of the duct 1 is provided with a suitable bore.
• the evacuation duct 1 extends axially the tube T by passing through a nozzle 2.
• the nozzle 2 is, moreover, rigidly connected to a housing
• the reservoir R is, in the embodiments of the figures, enclosed in a housing B delimited at its upper part by the end piece 2 and at its lower part by a base 3 forming the bottom.
• the housing B is optionally removable in order to allow recharging of the housing or filling of said reservoir.
• the end piece 2 is extended downwards by a substantially cylindrical skirt 2a provided, at its lower part, with fixing members 23 intended to cooperate with complementary members 32 formed on the base 3 so to rigidly connect the end piece 2 to the housing B.
• the skirt 2a of the end piece 2 partially forms the side wall of the housing B and can be produced (figure 2b) in one piece with the end piece 2 or in the form of an independent piece, intended to be assembled (figure 2a).
• the upper end 1b of the duct 1 is provided with a spray nozzle 10.
• the dispenser of the invention comprises at least one, and here, two diametrically opposite fins 11, 12.
• the fins 11,12 are each provided with a cam 110,120 intended to cooperate by sliding contact with an inclined wall 21,22 secured to the end piece 2. These fins are engaged either with the nozzle tube T as in the mode of embodiment of Figures la and lb, either with the tank R as in the embodiment of Figures 3a and 3b.
• the length of the inclined walls 21, 22 is adjusted as a function of the stroke necessary for the tube T to allow the delivery of a determined dose of product. Maintaining the position of the housing B and the end piece 2 relative to the reservoir R or to the tube T is ensured by appropriate fixing means ensuring a rigid connection which is sufficient to guarantee the accuracy of the doses of product withdrawn.
• the cooperation between the cams 110, 120 of the fins 11, 12 and the inclined walls 21, 22 of the end piece is such that a substantially radial thrust on at least one of the fins causes a sliding down or up which causes in turn, an axial approximation of the tube T relative to the reservoir R.
• the relative stroke of the tube T corresponds to the actuation of the sampling means P leading to the delivery of a dose of product.
• openings 20 intended to receive with slight play, the outer flanks lie, 12c of the fins 11,12.
• the external flanks lie, 12c extend in the openings 20 flush with the surrounding wall of the skirt 2a so as not to create discontinuity on the housing and to retain its cylindroconical profile of revolution.
• the edges of the openings 20 are advantageously bevelled.
• the external flanks lie, 12c form push-buttons and have generatrices which are at least partially parallel to those of the duct 1.
• the visible faces of the sides llc, 12c are provided with grooves 13 to facilitate manual support while avoiding any sliding.
• the cams 110, 120 are produced in the form of bosses carried by the upper part of the inner flanks 11b, 12b of the fins 11, 12 and the inclined walls 21, 22 are oriented towards the bottom of the duct 1.
• the fins 11, 12 are attached to the duct 1 by connecting arms 1a, 12a forming spacers and which extend substantially perpendicular to the side wall of the said duct.
• link arms are integrated in a disc mounted coaxially on the conduit 1.
• the internal flanks 11b, 12b extend the arms 11a, 12a upwards away radially from the duct 1 and provide the connection with the external flanks 11c, 12c.
• the inner sides 11b, 12b are provided with stiffeners in the form of ribs 111,112 which allow, however, to retain a certain flexibility in deformation.
• the conduit 1 slides here freely inside an axial bore formed in the solid end piece 2 while the reservoir R is immobilized inside the housing B.
• the upper end 1b of the duct 1 here projects freely outside the end piece 2 at least in the distributor's rest position.
• the base 3 comprises a cylindrical cavity 30 intended to receive the reservoir R and the dimensions of which are adjusted for this purpose in order to ensure its wedging by radial tightening.
• the cavity 30 is provided with a frustoconical upper bore 31.
• the fins 11, 12 are integral with the reservoir R which is here axially movable inside the housing B while the discharge duct 1 is fixedly mounted in the end piece 2 projecting towards the low.
• the reservoir R slides axially and in a guided manner in an internal bore 32 formed in the base 3 while the inner flanks 11b, 12b undergo bending towards the axis of the duct 10 under the effect of the radial thrust on the fins 11, 12 whose external sides llc, 12c are then housed inside the end piece 2.
• the inclined walls 21, 22 are oriented towards the top of the duct 1 and cooperate, still by sliding, with the lower edge of the outer flanks llc, 12c, forming a cam of the fins 11, 12.
