Definitions

• the present invention relates to a device for dispensing a determined dose of a liquid treatment product in a flush tank.
• Patent FR 2 808 897 has thus been proposed with a device consisting of a cleaning product storage tank, the lower part of which terminates in a tubular element opening into a cavity inside which is mounted a spherical shutter, which is integral with a float mounted floating on the surface of the water of the hunt.
• the amount of treatment product thus distributed depends essentially on the rise time of the spherical shutter from its low position to its upper position, and not on the volume of a storage cavity.
• a rise time is not a fixed datum since it depends on the state of a number of elements of the mechanism, the pressure of the water feeding the hunt, the height of the product in its container etc ... devices of this type are not able to deliver, each actuation of the hunt, identical precise doses of cleaning product.
• Drawer type devices have also been proposed, such as that described in patent FR 2,618,470, in which the cleaning product is contained in a storage container on the bottom of which is disposed a movable shutter sliding vertically under the action of a float controlled by the level of the water contained in the hunt.
• the float applies the shutter element in the up position, and when the flush is empty, the float drives down the shutter member which passes to the down position.
• This shutter element is designed so that in the high position, the storage liquid can penetrate into a cavity thereof, and that its lower part is closed and that, in the low position, the lower part of the shutter is in position. communication with the inside of the tank of the hunt and that the upper part is closed.
• the device proposed in US Patent 2,726,406 comprises a storage tank containing a disinfectant to be dispensed, provided at its base with an outlet which is closable by a valve secured to a float.
• the level of the water in the tank continues to rise, so that, according to the applicant, when the water level reaches that of the valve, the water then itself ensures the shutting off the flow of the product.
• a device has the drawbacks existing in the other devices mentioned in the prior art, namely the fact that the amount of product dispensed is a function of the filling time of the tank flush.
• the present invention aims to provide a device for delivering precise doses of cleaning products in which the filling time of the flush tank has an extremely low influence on the liquid product dose issued.
• the present invention thus relates to a device for dispensing a determined dose of a liquid treatment product in a flush tank, when actuated thereof, characterized in that it comprises:
• At least one metering cavity whose volume is close to that of the dose of product to be dispensed
• first means for placing this cavity in communication with a storage tank for said product second means for placing this cavity in controlled communication with the tank of the flush, the pressure drop of the first means being at least five times greater than the pressure loss of the second means,
• the metering cavity will be disposed in a vertical cylindrical element passing through the product storage tank.
• the metering tank will be placed under the storage tank, which will make it possible to use the entire volume of the latter.
• the first means of communication of the metering cavity with the storage tank may consist of an inlet port.
• the metering cavity will be closed at its lower part by closure means traversed by an outlet channel whose cross section is at least five times greater than that of the inlet orifice.
• the shutter elements may consist of a valve whose actuation is controlled from said float mounted member on the surface of the water contained in the tank of the flush. This valve may be mounted mobile in translation or rotation. According to the invention, it will also be possible to provide means capable of placing in communication an auxiliary reservoir with the metering cavity, so as to increase the volume (V + V + v) of the delivered product.
• said floating mounted member may be hollowed, at its upper part, with a cavity intended to collect the product dispensed by the sealing elements, extending by grooves able to distribute said product on its surface.
• the upper part of the latter may be in communication with an external filling container, possibly closed by a lid.
• the flush tank may include at least two water inlet ports, one of which is used to ensure the attachment therein of the storage tank, this orifice can further ensure the placing the latter in communication with the external filling container.
• Figure 1 is a partial vertical sectional view of a device according to the invention attached to the inner wall of a tank of a flush, shown in the waiting position of the flush,
• FIG. 2 is a partial vertical sectional view of the device according to the invention of FIG. 1 represented in the hunting actuation position

• FIGS. 1 and 2 show a device 1 according to the invention which consists of a cylindrical storage container 2 which is fixed on the internal face of a wall 3a of a flush tank 3.
• a device 1 which consists of a cylindrical storage container 2 which is fixed on the internal face of a wall 3a of a flush tank 3.
• the side wall of the storage container 2 is pierced with an orifice 4, this orifice, and a corresponding orifice 5 of the wall 3a, are traversed by a screw 7 immobilized by a nut 8 with interposition of a sealing washer 9.
• the container 2 is traversed axially by a cylindrical tubular element 10 whose lower part ends in a cavity 12 whose volume V corresponds substantially to the volume of a dose of the product 6 which is contained in the container 2.
• the cavity 12 is closed at its lower part by a plug 17 which is pierced by an axial and longitudinal channel 19 of diameter D.
• the cavity 12 communicates with the interior of the container 2 through an orifice 14 whose diameter d is much smaller than the diameter D.
• the tubular element 10 is traversed by a longitudinal channel 16 placing the internal volume V of the cavity 12 in communication with the atmosphere and thus acting as a vent.
• the outlet orifice of the channel 19 is closed by a shutter system controlled by a float mounted floating on the surface of the water inside the tank 3 of the flush. More specifically, this closure device consists of a cylindrical piece 20 pierced at its upper part with an orifice 22, extending inwardly through a cavity 23, the diameters of the latter and the orifice 22 being such that the cylindrical piece 20 can be inserted around an O-ring 24 embedded in a circular groove of the cylindrical member 10 and which constitutes a stop.
• the cavity 23 is provided with an annular support zone 26 which provides the sliding guide of the cylindrical part
• the lower part of the cylindrical part 20 is provided with an external thread on which is screwed a cylindrical cap 25 whose inner face is hollowed to receive a shutter valve 28.

• the cap 25 is extended downwards by a central rod 31 integral with a float 32.
• the level N of the water inside the tank 3 of the flush is such that the float 32 applies the flap 28 against the outlet of the channel 19 thus ensuring shutting it off.
• the treatment liquid contained in the container 2 flows, through the orifice 14 formed in the cylindrical element 10, into the cavity 12, expelling the air contained therein by the vent 16.
• the diameter d of the orifice 14 is small, that is to say for example of the order of 0.6 mm, the filling time of the cavity 12 is relatively long, which is hardly binding in the this is the period during which the flush is not used.
• the volume vs' flowing through the orifice 14 will be approximately 0.1 cm 3 which represents a small value relative to the volume V of the cavity 12, the volume of overall product delivered V + v thus being equal to 2 + 0.1 cm 3 .
