Abstract

The subject of the invention is an improvement to a pourer-metering device. A means acting as a shut-off D-31 closes the passage of the liquid between the said metering device-pourer and the bottle, if the other orifice which permits the passage of the liquid between the vessel D-17 and the dispensing jet D-26 is not yet closed. Pourer-metering device, particularly for liquid, in which the said shut-off D-31 comprises several parts, a cylindrical part D-32, which closes the passage, a base, which makes it possible to rest on the head of the assembling screw D-30 or to be fixed thereon in the extension of the cylindrical part, and a part D-35 acts as a guide for the shut-off D-31 in the flange D-3 of the vessel cap. The invention applies to a pourer-metering device, particularly for liquid.

Description

 The subject of the invention is an improvement to a pourer-doser of the kind in which the apparatus comprises a tank which is surmounted by a tubular end-piece for receiving the liquid to be dispensed from a bottle threaded with the neck at the bottom, on this end-piece , and from which a predetermined dose of liquid can be drawn off through a lower tube provided with a suitable valve system which is raised from the bottom up.

A pourer-doser has already been described in a patent for invention filed in France on August 16, 1963 under the number 1 366 459 by Monsieur
Eugene ATLAN. This type of pourer-doser has many advantages, it distributes by simple pressure of the glass on its sheathed branches, a dose of liquid varying according to the model. It ensures easier, faster service. On the other hand, the ration is not necessarily always exact. Indeed, in the instructions supplied with this type of pourer, it is clearly indicated, once the appliance is ready to operate
"place the glass under the sheathed branches and press upward, as much as possible, with a dry gesture and without relaxation. Do not remove the glass until the dose has completely flowed out and always with a sudden movement".

 Without following these instructions to the letter, the dose or ration of liquid poured into the glass is not exact, which is very annoying for a measuring device, that is to say if the user in the phase ascending mechanism slows down its action, or if in the descending phase, it withdraws its glass slowly without sudden movement, the liquid continues to flow, in one and / or the other case, during the fraction of the race or the closing of the finish coming from the bottle is not yet done.

 The object of the invention is to remedy this drawback. It makes it possible whatever the mode of use of the pouring-doser to always obtain the same dose of liquid.

 To this end, the invention is characterized in that it is composed of a shutter, which is arranged at the upper level of the mobile assembly. This obturator replaces the obturator seal which was usually placed at the same level of the axis head.

The mobile shutter according to the invention comprises a first part which acts as a seal, a second part which acts as a shutter intended to close the orifice of the nozzle which allows the passage of the liquid between the bottle and the tank. This second part
is extended by a long cylinder so as to keep the said passage closed, when the mobile assembly goes up or down and the liquid passage between the tank and the dispensing tube is not yet closed. The shutter according to the invention is therefore extended relative to the simple seal previously described and used. In addition, the movable shutter is ballasted at its base so as to rest properly on the assembly screw of the axle cap.

 The obturator seal is removed so as to allow a stroke of the mobile assembly increased by several millimeters. The exhaust windows are also lowered by a few millimeters. The valve stem is also shortened.

 The attached drawings given by way of indicative and non-limiting example will easily make it possible to understand the invention. They represent a preferred embodiment according to the invention.

D-17 containing the liquid.

In Figure 3 in the first phase of the movement, the first push of the glass on the control arms D-28 raises ~ the distribution jet D-26 to the base of the central axis D-19, releasing the shield -drip D-27, and thus freeing the lower evacuation orifice
D-38.

 In FIG. 4 which represents the last phase of the movement, the continuous thrust exerted on the control arms of the distribution jet D-28 causes the central axis D-19 to rise as well as all the parts integral with this axis, constituting the mobile assembly D-40.

Gradually takes place
10 / clearing the windows D-39 the central axis allowing the evacuation of the liquid contained in the tank,
20 / the air intake opening D-41 the base of the air valve
D-5 being lifted by pushing the D-14 axle cap
30 / the closing of the arrival of the liquid coming from the bottle, the obturator seal D-13 coming up against the orifice of the flange D-3.

Figure 5 shows the main drawback of the current pourer-doser. Between the first phase of the movement (fig. 3) and the last (fig. 4) the ascent to the top of the mobile assembly D-40 goes through an intermediate phase (fig. 5) during which all the orifices
D-33, D-38 allowing the passage of the liquid are open, the closing of the inlet coming from the bottle not yet being carried out.

 Maintained in this position, the metering device dispenses an additional quantity of liquid, uncontrolled, as long as the pressure exerted on the mobile assembly D-40 has not been conducted to its maximum, to reach the position indicated in FIG. 4 It is the same in the downward phase of the mechanism.

 The passage of the liquid is represented by the arrows A and B.

 Figure 6 in the starting position.

Observations
the movable shutter (ballasted) D-31 rests on the assembly screw
D-30
the seal D-13 was removed allowing a stroke of the mobile assembly D-40 increased by about 2 mm
. the evacuation windows have been lowered by about 2mm
the air valve stem D-5 has been shortened.

 In FIG. 7, which represents the first phase of the movement, the first push of the glass on the control arms D-28 causes the distribution jet D-26 to go up to the base of the central axis D-19, releasing the D-27 drip guard, and thus freeing the lower evacuation orifice.

 All other parts remaining stationary.

 In FIG. 8, which represents the second phase of the movement, the mobile shutter D-31 begins to slide in the tubing of the flange D-3 in the part corresponding to the small diameter, already exercising its function, thereby preventing any arrival of liquid from the bottle and trapping at the same time that contained in the tank.

 In figure 9, which represents the last phase of the movement.

Continuing the upward push, the ascent of the central axis
D-19 progressively penetrates the upper part of the movable shutter into the tubing of the flange D-3 corresponding to the small diameter, but also its base, into the tubing of the flange corresponding to the large diameter, thereby ensuring a double seal .

 Simultaneously, the air intake valve D-5 is actuated by the thrust of the axle cap D-14; the evacuation windows are cleared. The dose of liquid trapped in the glass flows. The drawback described in FIG. 5 can be considered as a serious defect, for a device used as it is as a measuring instrument, because of the difficulty which results from obtaining the precision and regularity essential in distribution. a pre-determined dosage.

 Indeed, it will not be obtained in a rigorously exact manner, with the same device, according to the use which will be made of it, following a deliberately or involuntarily incorrect manipulation, depending on whether one will extend more or less the passage time of the liquid during the intermediate phase in question.

 This drawback can be particularly harmful in the event of strict control, or of management based on an accounting of the doses served (and a fortiori if the device is equipped with a counter for this purpose).

 The elimination of the defect requires the need to obtain, by appropriate technical means 10 / the imprisonment in the tank of the desired dose of liquid, before any possibility of evacuation thereof, and 20 / simultaneously, the prevention of any arrival of additional liquid from the bottle.

 This objective is fully achieved thanks to the device described according to Figures 6, 7, 8 and 9.

 NB - Apart from the structural modifications indicated in Figure 6 relating to the removal of the obturator seal D-13 the displacement of the evacuation windows of the central axis D-19 the shortening of the air valve stem D-5 the technical characteristics of the shutter may vary.

 Different designs or embodiments, in addition to that recommended, can be envisaged.

 The shutter can in fact either a) be integral with the separating strip D-8, made free by the removal of the retaining pins, under the nut of the plug D-7 b) be integral with the movable assembly, in the measurement or the precision of the machining of the component parts, as much as their adjustment relative to the axis of the metering device, allow its sliding, without risk of blocking during operation, c) have a flange in its lower part, including the head of assembly screw D-30, after modification thereof.

In Figures 10, 11, 12 and 13 which show the shutter
D-31 according to the invention, there is a first part D-32 which obtains the passage D-33 from the bottle towards the tank D-17. The D-34 base of the D-31 shutter may be ballasted. The cylindrical part D-32 can be extended by a strip D-35 or by fins D-36 and D-37, which act as a guide for the obturator D-31 in the passage D-33 of the flange D-3 .
