Definitions
- the present invention relates to a device for dosing a liquid or gel product.
- the device of the invention is of the type comprising a dispensing head movable axially by covering a product reservoir and provided with an outlet conduit and a metering chamber delimited, on the one hand, by a check valve. intake and, on the other hand, by a piston whose rod is connected to said head and which is equipped with an exhaust valve.
- these devices generally comprise a return member for the head in the high position consisting of a metal helical spring.
- EP 0 974 401 discloses a device of this type, provided with a return spring for the head in the high position, in which the piston rod extends inside the chamber by a projecting lower end ensuring tight locking the intake valve in the low position of the head and in which the chamber is formed in a cylindrical socket provided with an upper collar for hooking on the edge of the tank.
- the head is retained in the high position with respect to a separation from the reservoir by a flange.
- the head is retained in the low position by a bayonet system which is implemented by pressing on the head and rotating the latter.
- a bayonet system which is implemented by pressing on the head and rotating the latter.
- a slight vertical movement of the head is possible and the sealing of the valve locking may not always be ensured.
- the head can easily be moved down, causing untimely actuation of the device.
- the present invention aims to solve these technical problems satisfactorily.
- the dispensing head comprises an external lateral skirt provided with first blocking means capable of cooperating by snap-fastening with second lower blocking means provided on said flange to block the head in the low position. and likely to cooperate with second upper locking means to retain the head in the high position, vis-à-vis a tearing and to the fact that the device is free of a means for recalling the movement of the dispensing head.
- the first locking means are formed in the lower part of the external side skirt.
- the first blocking means are formed by a blocking rib, while the second lower blocking means are formed by a bottom necking.
- the second upper locking means are advantageously formed by an upper rod capable of retaining the locking rib.
- This rib and this rod can be dimensioned to generate, during the sliding of the skirt of the head against the collar, frictional forces requiring the application of a determined minimum force to move the head.
- the second upper locking means can cooperate by snap-fastening with the first locking means in the high position of the head.
- these second upper blocking means can be formed by an upper neck, similar to the lower neck.
- said collar is provided with a vent orifice possibly extended by a groove formed on the external wall of the sleeve.
- vent orifice is advantageously arranged through a connecting shoulder with the body of the socket.
- said head has a cylindrical internal wall, coaxial with said skirt, and intended to close the vent orifice in the low position of the head.
- the piston rod comprises an axial ejection conduit opening, in the upper part, into a cavity of said head where the exhaust valve is housed.
- said cavity is formed in a sleeve integral with the lower part of the head and connected coaxially to the upper end of the piston rod.
- the upper wall of said cavity is provided with channels communicating with the product outlet conduit.
- the intake valve comprises an axial tube projecting inside the chamber and into which engages the lower end of the piston rod in the low position of the head.
- the side wall of said tube comprises at least one lumen for the passage of the product.
- the intake valve and / or the exhaust valve comprise a movable sealing ball.
- the device of the invention overcomes a simple structure consisting of few parts of any spring type return means. It is also easy to manufacture, and therefore reliable and economical.
- This device finds its application both in the field of pharmacy where it can allow the dosing and distribution of syrups in particular as in the field of cosmetic or food products.
- FIG. 1 shows a sectional view of an embodiment of the device of the invention.
- FIG. 2A to 2D show sectional views of the device of Figure 1, mounted on a product tank, during the various phases of distribution.
- the device shown in Figure 1 is intended for dosing liquid or gel products.
- the device comprises a dispensing head 1 movable axially by covering a reservoir R of product (of which only the neck C is visible in FIG. 1).
- the head 1 is provided with a product outlet conduit 11.
- the device also comprises a metering chamber 20 delimited, on the one hand, by an inlet valve 22 and, on the other hand, by a piston 3 whose rod 31 is connected to the head 1.
- the piston 3 is equipped an exhaust valve 32.
- the intake and exhaust valves each comprise a movable sealing ball.
- the chamber 20 is formed here in a socket 2 with cylindrical-conical body, provided with an upper flange 21 for hooking on the edge of the neck C of the reservoir.
- the rod 31 of the piston 3 is extended inside the chamber 20 by a projecting lower end 31a which locks the intake valve 22, in the low position of the head 1.
- the head 1 comprises an external lateral skirt 12 provided at its lower part with a blocking rib 12a capable of cooperating with two blocking stops formed on the external wall of the flange 21. These two stops are formed respectively by an upper rod 21a limiting the stroke of the head upwards and of a lower constriction 21b ensuring the retention of the head 1 in the low position by removable snap-fastening of the rib 12a.
- the inner periphery of the skirt 12 has an annular groove 12b into which the snap ring 21 a enters in the low position of the head 1.
- the end 31a of the piston 31 can very slightly collapse elastically against the valve 22 and / or the seat 2a of the valve 2 can slightly deform elastically to ensure the tight closure of this valve.
- the axial displacement of the rod 1 is carried out by manual pulling or support in pull-push mode in the absence of any return means and in a guided manner by sliding contact of the rib 12a on the external wall of the collar 21, between the two stops 21 a, 21b.
- the flange 21 is provided, where appropriate, with a vent orifice 210. This orifice is disposed through the shoulder 212 for connection with the body of the sleeve 2.
- this bleeding is not necessary because there is an intermediate space allowing the passage of the air intake in the tank via the orifice 210.
- the very slight clearance existing between the internal wall of the skirt 12 and in particular the rib 12a, on the one hand, and the external wall of the flange 21, on the other hand, is sufficient to allow air to be taken up.
- the head 1 has a cylindrical internal wall 14 located coaxially and radially inside the skirt 12 and intended to close the vent orifice 210 in the low position of the head 1.
- the wall 14 is arranged in line with the orifice 210 and its thickness is greater than the diameter of the orifice 210.
- the wall in which the shoulder 212 is formed may slightly deform elastically towards the interior of the container under the effect of the pressure exerted by the cylindrical wall 14 to guarantee the obturation of the vent 210.
- the rod 31 of the piston 3 comprises, over its entire height, an axial ejection conduit 30 opening, in the upper part, into a cavity 10 of the head 1 where the exhaust valve 32 with ball is housed.
- the lower end of the conduit 30 delimits the orifice for discharging the product from the chamber 20.
- the cavity 10 is formed in a sleeve 13 integral with the lower part of the head 1 and connected coaxially to the upper end of the rod 31.
- the upper wall of the cavity 10 is provided with a network of channels 10a communicating with the product outlet conduit 11 and allowing the passage of the product when the ball of the valve 32 is pressed against said wall during the dispensing phase (see FIG. 2C) under the pressure of the ejected product.
- the intake valve 22 comprises an axial tube 23 which projects inside the chamber 20 and into which engages the lower end 31a of the rod 31 of the piston 3 in the low position of the head 1.
- the side wall of the tube 23 includes at least one lumen 23a allowing the transverse passage of the product during the filling phase of the chamber by mounting the head 1 and suction of the product as shown in FIG. 2B.
