    The invention relates to equipment for dispensing liquids, in particular to devices for storing and dispensing dispensing thickening liquids. It can be used primarily in the preparation of drinking liquids consisting of metered amounts of syrup or concentrate and water and / or other constituents. 1θ
    A device for storing and dispensing dispensing thickening fluids is known, which contains a container for holding a liquid (bottle) with an outlet neck and a removable dispensing device mounted on the last 16 [11.
    The dosing device does not provide accurate dosing ^ of thickening liquids when their temperature fluctuates **.
    The aim of the invention is to increase the accuracy of dosing by preventing the formation of a crust on the surface of the liquid, and also regardless of fluctuations in the temperature of the liquid.
    To this end, the device is equipped with a surge vessel filled with gas and placed in the tank so that its open end faces the neck and is in communication with the atmosphere in the dispensing position.
    To store liquids at a temperature below their freezing point, at least one of the sections of the vessel wall must be made of elastic material or made corrugated.
    In order to fill the entire container with a liquid and increase the degree of tightness, when closing, the edge of the equalization vessel is equipped with an annular flange interacting with the end of the neck.
    It is desirable that, at the junction of the neck and the wall of the vessel wall, the vessel wall was made curved in the shape of the mouth of the vessel entering the vessel at least on a part of its circumference.
    It is advisable to equip the dosing device with one or more pins designed for piercing the curved part of the wall.
    The flange of the vessel can be rigidly bonded to the end of the neck.
    Figure 1-3 presents the proposed device (at various points in the dispensing fluid), a vertical section b® in Fig.4-7 - device (options).
    7335.11
    The device contains a container 1 for liquid, which in the dispensing position is at level 2. A cavity 3 is formed in the upper part of the container, the pressure in which is slightly lower than atmospheric, which makes it possible to set the corresponding evaporation pressure, which eliminates the formation of a crust on the surface of a liquid with a high content Sugar container G has an outlet neck 4 with a screw thread 5, onto which a cap 6 can be screwed, which serves as a holder for a removable metering device, for example an electromagnet outlet valve. The valve consists of an electromagnetic coil 7, a protective cap 8, which has a guide sleeve 9 in the center and is included in the last hollow core 10. The core is open at the rear end made of non-magnetic material, and at the front end it is made with drain holes 11 in the conical section 12 the walls. The conical section 12 by means of an annular seal 13 is connected with the conical section of the sleeve 9 having an outlet 14. '
    An insert 15 is located inside the cap 6, which interacts through an air-tight ring seal with the end surface of the neck 4. An element 16 is installed on the insert 15, one or more holes 17. The side insert is the top 20.
    an element 16 is installed having a wall and a tube 18 on the wing. 15 also has a tube 19, on the end of which a tube is mounted, an equalizer made in the form of a
    In the container vessel 21, the stake and placed in such a way, its open end faces the neck, and the tubes 18,19,20 enter inside it. Through the tubes. 20.19 and the recess 22 in the cap 6, the cavity of the vessel 21 is constantly in communication with the atmosphere, i.e. it contains air at atmospheric pressure. The boundary of the air in the vessel and the liquid located in the tank 1 is determined by the lower edge of the vessel 23 and does not depend on the changing liquid damage 2. Decreased pressure in the cavity. 3 is ensured that the fluid flows through the openings 17 into the metering chamber 24 into the core 10 always at the same statistical pressure, since it constantly tends to penetrate into the cavity of the vessel 2 1,
    The device operates as follows.
    Before the start of delivery (see, Fig. 1), the core 10, under the action of gravity, occupies the lowest position at which the outlet opening 14 closes and the liquid from the container 1 passes through the opening 17 into the metering chamber 24 (arrow 25).
    After turning on the coil 7, the core is retracted into the sleeve 9 (see figure 2), and its upper non-magnetic part covers the holes 17, cutting off the liquid dose equal to the volume of the chamber 24. Through the holes 11, the liquid flows (arrow 26) into the space between the core and the sleeve 9, and then into the outlet 14. After a certain period of time necessary for the dose, the coil 7 is turned off and the core 10 is lowered again by gravity to its original position (see Fig. 3). The liquid again enters through the openings 17 (arrow 25) into the metering chamber 24, and the corresponding amount of air, due to the fact that the pressure in the cavity of the vessel 21 is atmospheric, flows in the form of bubbles 27 through the liquid column upward (arrow 28). Outside air fills again (arrow 29J vessel. Thus, the same static pressure is always maintained over the openings 17, which ensures a uniform flow of fluid into the openings at equal intervals regardless of the level of fluid in the tank 1. This is especially important for so-called self-preserving fluids with a high sugar content, prone to crusting on the surface due to drying out in contact with air, and it is not necessary to complicate the design of the device by introducing heat spruce with heating control to maintain a certain viscosity of the liquid (an increase in viscosity leads to the fact that at equal intervals a different amount of liquid is dispensed.) Further, in the presence of temperature fluctuations, a change in the pressure of the liquid is excluded, since the gas in the cavity 3 expands freely without changing the position level 2.
    In particular, if tank 1 is emptied by 1/3, then with temperature fluctuations between 10 and 30 ° C, for example, as a result of day and night changes, expansion of the air in the absence of a surge vessel can lead either to destruction of the tank Or to a sharp opening of the outlet valve, which does not provide metering accuracy.
    In the proposed device, the air, which expanded as a result of the temperature increase, is forced out into the vessel, therefore, the static required to release the liquid, the pressure is stored without special cooling systems.
    After the tank 1 has been completely emptied, the exhaust valve is removed and the surge vessel, insert and other elements are removed — the tank can be filled again with liquid.
    3 3 511 The proposed device can also be used to store liquid, for example, during its transportation (see Fig. 4). A cap 30 is screwed onto the neck of the container 1, which serves for hermetically locking the container using the sealing flange 31.
    Equalization vessel 21 is filled with air or inert gas, and its edge is located in the neck and can be made in one piece with the flange 31 and the pipe 32 for communication with the atmosphere when the liquid is discharged. An opening 33 is formed in the flange to accommodate the volumetric metering device 34 after removing the cap 30 and screwing on the cap
    6..
    To dispense liquid, the container should be turned upside down, with the tube 19 falling into the tube 32, thereby providing the desired connection. The location of the edge of the vessel 21 in the neck 4 allows you to almost completely fill the container with liquid, while at the same time ensuring tightness of closure.
    The vessel 21 near the neck 4 may have at least one opening 35, which, in order to prevent liquid from entering the vessel during transportation of the device 30, may be covered by a tear film 36.
    In order to store liquid in a container at a temperature below its freezing point, it is advisable that at least one section of the wall of the vessel 21 be made of elastic material or corrugated. Variants of such a device are shown in FIG. 5 and 6. ' A cap 40 37 is screwed onto the neck 4 of the container 1, and the edge of the equalization vessel 21 is made with an annular flange 38. To communicate with the atmosphere, the holes 39 in the cap 37 (see figure 5) or in the film 40, stretched over the edge 45 of the neck ( see figure 7). Instead of these openings, a breathable cap may be used.
    In the wall of the vessel 21 there is one jq or several sections 41 made of elastic material (see
    figure 5). At least the wall in one area or the whole can be completely corrugated (see figure 6). With an increase in the volume of liquid filling the container 1, for example, when it freezes, the walls of the vessel stretch and compensate for this change in volume, which prevents the destruction or change in the shape of the container. The holes 39 at 60 serve to release air from the vessel 21. At the same time, they can also serve to receive nozzles 42 of the key 43, with which the cap 37 is unscrewed. 65
    In the device shown nafig. 5, an additional device can be provided for holding the cap 37 and the exhaust valve, for example a bayonet lock, and in the device shown in FIG. 6, the flange 38 of the vessel 21 is rigidly fastened to the end of the neck 4 and serves as the only seal for tightly closing the container 1 when fitted dosing device.
    To communicate with the container 1 with the dosing device at the junction of the neck 4 and the container wall ·. The wall of the vessel 21 is made curved in the form of a ledge 44, at least part of its circumference entering the inside of the vessel. The wall in this section, when fixing the dosing device, must be punctured manually or automatically using one or more pins 45, with which the device is equipped. Liquid flows into the hole formed (arrow 46) into the metering chamber, as described above.

The core is open at the rear end made of non-magnetic material, and at the front end it is made with drain holes 11 in the conical section 12 of the wall. The conical section 12 is connected by an annular seal 13 to the conical section of the sleeve 9, which has an outlet 14. Inside the cap 6, there is an inlet 15, which interacts through a hermetic annular seal with the end surface of the neck 4, one or several openings 17 in the side wall and the tube 18 on the crest. The insert 15 also has a tube 19, the upper end of which is mounted on the tube 20. In the tank 1 there is an equalizer; .1b vessel 21, made in the form of a stake and placed like this m, Thu its open end facing the neck-not, and the tubes 18,19,20 entrance inwardly it. Through the tubes, 20,19 and the recess 22 in the cap b, the cavity cavity 21 is permanently connected with the atmosphere, i.e. it contains air at atmospheric pressure. The boundary of the air in the vessel and the fluid located in the container 1 is determined by the lower edge of the vessel 23 and is independent of the changing level of liquid 2. Low cavity pressure. 3 is ensured by the fact that fluid flows through the openings 17 into the dosing chamber 24 inside the core 10, always at the same statistical pressure, as it constantly strives to penetrate into the cavity of the vessel 21, the device operates as follows. Before delivery (see Fig. 1), the wand 10 under the action of gravity takes the lowest position in which the outlet 14 is closed and the liquid from the tank 1 passes through the opening 17 into the dosing chamber 24 (arrow 25). After turning on the coil 7, the core 10 is drawn inward of the sleeve 9 (see Fig. 2), and its upper non-magnetic part closes the holes 17, the compartment has a dose of liquid equal to the volume of the chamber 24. Through the holes 11 the liquid flows (arrow 26) into the space between the core and the sleeve 9, and then into the outlet 14. After a certain period of time required to deliver a dose, the coil 7 is turned off and the core 10 is lowered again under the force of gravity to its original position (see Fig. 3). The liquid re-enters through the holes 17 (arrow 25) into the dosing chamber 24, and the corresponding amount of air, due to the fact that the pressure in the cavity of the vessel 21 is atmospheric, in the form of bubbles 27 passes through the liquid column up (arrow 28). Outside air refills (arrow 29). Thus, the same static pressure is always maintained above the openings 17, which ensures a uniform flow of fluid into the openings at regular intervals regardless of the level of the liquid in the tank 1. This is especially important for so-called self-preserving, high-sugar liquids that tend to form a crust on the surface due to drying out when in contact with air J, without the need for complicating the design of the device by introducing heat a thermostat-controlled rotator for boosting a certain fluid viscosity (an increase in viscosity results in a different amount of fluid being emitted at regular intervals). Further, in the presence of temperature fluctuations, a change in fluid pressure is excluded, as the gas in cavity 3 freely expands, not changing the position of level 2. In particular, if capacity 1 is emptied by 1/3, then with temperature fluctuations between 10 and 30 ° C, for example, as a result of changing the day and night, the expansion of air in the absence of an equalizing vessel Jette lead either to the destruction of the container or in a dramatic opening of the exhaust valve, which does not ensure the accuracy of dosing. In the proposed device, the air that expands as a result of an increase in temperature is displaced inside the vessel, therefore the static required for the liquid to escape, the pressure is maintained without special cooling systems. After the final emptying of the tank 1, the outlet valve is removed, as well as the leveling vessel, the insert and other elements are removed - the tank can be refilled with liquid. The proposed device can also be used for storing a liquid, for example, during its transport (see Fig. 4). A cap 30 is screwed onto the neck of the tank 1, which serves to seal the container tightly using a sealing flange 31. Equalizing vessel 21 is filled with air or an inert gas, and its edge is located in the throat and can be made in one piece with the flange 31 and the tube 32 for communication with the atmosphere when dispensing the liquid. A hole 33 is formed in the flange to accommodate the volume metering device 34 therein after removing the cap 30 and screwing in the cap 6. L. In order to dispense the liquid, the container should be turned upside down, while the tube 19 falls into the tube 32, thus providing the required connection. The arrangement of the edge of the vessel 21 in the neck 4 makes it possible to almost completely fill the container with liquid, while at the same time ensuring the tightness of the closing.

May have at least one opening 35, which, in order to avoid liquid getting inside the vessel during transportation of the device, can be closed with a ruptured film 36. the walls of the vessel 21 to perform of elastic material or corrugated. Variants of such an arrangement are shown in FIG. 5 and 6. Cap 37 is screwed on the neck 4 of container 1, and the edge of leveling vessel 21 is provided with an annular flange 38. To connect the vessel with atmosphere, oTBelicfHR 39 is used in cap 37 (see Fig. 5 or in film 40 stretched to the edge). neck (see Fig. 7). Instead of these holes, a permeable air cap can be used. In the wall of the vessel 21 there is one or more sections 41 made of elastic material (see Fig. 5). At least a wall in one section or all can be completely corrugated (see Fig. 6). As the volume of liquid increases, filling The container 1, for example, when it is frozen, expands the vessel wall and compensates this volume change, which prevents the container from breaking or changing its shape. Holes 39 are used to release air from the vessel 21. At the same time, they can also 43, with which the cap 37 is unscrewed. In the device, as shown in Fig. 5, an additional device can be provided to hold the cap 37 and the exhaust valve, for example, a bayonet lock, and in the device shown in FIG. B, the flange 3 8 of the vessel 21 is rigidly fastened to the end of the neck 4 and serves as the only seal for hermetically sealing the container 1 when the dispensing device is seated.
