Description

 The invention relates to a dispensing device for spilling a liquid product under pressure from a hermetically sealed container.

 The invention allows to create a device with a locking mechanism for dispensing liquids, such as non-carbonated under pressure and carbonated drinks, which is adapted for hermetically sealing containers, such as containers made of glass or PET / polyethylene terephthalate / with pressurized contents above atmospheric, in particular soft drinks.

 For hermetic closure of various containers with carbonated and pressurized liquids, up to now, one-time screw-threaded plugs are used, the disadvantage of which is the impossibility of dispensing a drink throughout the entire consumption process, which leads to a loss of carbonated taste. In addition, if the bottle has a capacity of 1 liter or more, then the extraction of liquid from such a container gives a number of inconveniences associated with the total weight, with the possibility of foaming and involuntary leakage of the drink.

 Some types of threaded disposable cap plugs include a valve for dispensing dispensed non-pressurized fluid. However, the use of such plugs becomes impossible for containers with liquid under pressure.

 Therefore, it would be advisable to obtain a solid plug / type of siphon /, which in this case is capable of most efficiently supplying liquid, including carbonated, as well as tight closure of the container.

 Known siphon for dispensing carbonated drinks, containing a vessel and a head with a node for dispensing a drink and a node for supplying compressed gas to the vessel. The latter is located in the nozzle of the head and includes a check valve located sequentially from the center, the needle body with the hollow needle, the cartridge sealing sleeve and the nut holding the sleeve in the socket of the nozzle. The disadvantages of the siphon include the fact that it has large dimensions, a larger number of assembly units, significant material consumption and, as a consequence, a large cost price, as well as the impossibility of a single use / cm. US Pat. France N 1581039 /.

 A siphon is also known for dispensing fluid from a bottle / cm. US Pat. US 4860932 /, which consists of a housing wound on a container in which there is a discharge opening of the channel that conducts the fluid, a shut-off valve with a seat for locking the fluid, a hollow tube reaching the bottom.

 Also known is a device for dispensing a liquid, which comprises a housing, a liner, a tube, a channel (see France, 990900, B 65 D 83/14, 09.27.51). This object is selected as a prototype.

 The disadvantages of this object include a greater number of parts, more complicated assembly, its relatively high cost, and also the heterogeneity of the material from which this siphon is made.

 The aim of the present invention is to provide a dispensing device such as a siphon plug for dispensing a liquid under pressure, which is more convenient during operation, allows more economical use of the liquid in it. In addition, when creating this device consumes less material and, therefore, entails a lower cost, and subsequently a lower price when entering the market. Also, this device is easier and faster to assemble.

 This result is achieved in that in a device for dispensing a liquid under pressure, comprising a housing with a spring pressure plate in its upper part, hermetically connected with it to move along the axis, a channel, a flange with a shank, a tube reaching the bottom of the tank, however, on the inner side of the plate contains a rod with a cone-shaped valve that is installed in the working position by forcing through a cone-shaped hole in the flange.

 In addition, the spring pressure plate has concentric grooves.

 A device for dispensing a liquid under pressure containing a housing, the upper part of which contains a spring pressure plate made with it as a whole, a nozzle with a channel that conducts liquids, a valve for locking the liquid, a flange, a tube reaching the bottom of the tank, on the inner side of the plate there is a soldered rod with a spherical valve inserted through a flange, which consists of a softer and more homogeneous material with the body, and the spout is removable with the possibility of its mounting on the body q different angles.

 The spring pressure plate has radial stiffeners.

The invention is illustrated by drawings, where in FIG. 1 shows a general view of a container with a device for dispensing liquid;
in FIG. 2 - the same - the second option;
in FIG. 3-5 - implementation of the valve head;
in FIG. 6 - pressing plate
in FIG. 7 - the same - the second option;
in FIG. 8 - removable spout;
in FIG. 9 is a section AA in FIG. 6.

 The device according to the first embodiment contains a housing 1, a spout 10 with a channel 2, a fluid conducting channel - a pressure plate 3 and a valve 4 on the rod 5. The valve 4 is located in the hole 6 of the flange 7 having a shank 8.

 The device includes a tube 13, reaching the bottom of the container 14 with liquid 15. The plate 3 is inserted into the groove 17 of the housing 1, in which the space 18 is formed.

 The plate has concentrating grooves.

 The device according to the second embodiment comprises a housing 1 with a space 18, a spout 10 with a channel 2 conducting a fluid, a pressure plate 3, made with the housing 1 as a whole. On the inner side of the plate 3, a rod 5 with a spherical valve 4 is inserted into the hole 11. The flange 7 is made of a material homogeneous with the housing 1, has a shank 8 and is installed in the housing 1 until it stops in the shoulder 9. The tube 13 reaches the bottom of the container 14 (bottle) .

 The spring pressure plate has radial stiffeners.

 The device operates as follows.

 The pre-assembled proposed plug with a locking mechanism is tightly screwed onto the container 14 (Fig. 1).

 Assembly is carried out in this way and consists of the following parts.

 The pressure plate 3 is inserted by pressing into the groove 17 in the housing 1. The tightness of the connection of the housing 1 and the plate 3 is ensured by specially selected dimensions and the fact that the pressure plate 3 is made of a softer material than the housing 1. The valve 4 then passes into the hole in the flange 7 due to the setting cone and elastic deformation of the valve material. The dimensions of the holes in the flange 7 and the valve 4 are selected so that the valve does not come back, but is pressed tightly in the hole 6 to the conical seat due to the spring loaded pressure plate 3. The elasticity of the pressure plate 3 is achieved by giving it one of the following forms / Fig . 6 and FIG. 7 /, namely, the pressure plate has concentric grooves in one case and radial ribs in the other. In the second case, radial stiffeners give greater elasticity than concentric grooves due to the radial arrangement.

 The tightness of the valve is also ensured by the greater elasticity of the material of the pressure plate 3 with respect to the housing 1. At the same time, the uniformity of the material of the entire tube is maintained. Next, the tube 13 is put on the shank 8, after which the plug is ready for installation.

 When the plug is installed on the container (bottle), after acting on the pressure plate 3, the valve 4 moves away from the seat and the liquid 15 passes through the gap formed, rising through the tube 13 due to excess gas pressure. Then it enters space 18, from where it goes out through channel 2. Upon termination of the impact on the plate 3 under the action of the elasticity of the plate and the pressure of the fluid, the valve 4 rises in the hole 6 and the fluid flow stops.

 Another assembly option of a device such as a siphon plug / FIG. 2 /.

 In this case, the pressure plate 3 and the housing 1 are made as one unit. The flange 7 is made of a material homogeneous with the housing 1, but softer to ensure the tightness of the valve 4 and the container 14 (bottle). The flange 7 is installed in the housing 1 until it stops in the collar 9. Next, the plate 3 is pressed and the rod 5 with the valve head 4 is inserted through the hole in the shank 8 and the flange 7 into the hole 11 made on the inside of the pressure pad, where it is fixed by thread or sealing. After that, the plate 3 is released and the valve 4 occupies the working position. Next, the tube 13 is put on the shank 8 and the cork is ready for use.

 Tightness is ensured by the monolithicity of the housing 1 and the pressure plate 3 and the fact that the flange 7, due to greater softness than the material of the housing 1 and container 14, acts as a sealing gasket.

 The valve 4 cannot be mechanically damaged when pushed through the flange 7. In addition, it becomes possible to apply various valve options that can withstand more pressure in the container 14 (Fig. 3-5).

 Cork - a siphon for dispensing a carbonated drink is assembled from a minimum number of parts; it can be recommended for single use in conjunction with widely used PEGF bottles.

 In this case, to speed up the installation of the cork on the bottle, it is proposed to replace the threaded connection with a lock.

 When using corks to dispense a beverage, it may be necessary to consume a beverage bypassing a glass. To this end, it is proposed to make the nozzle 10 with a channel 2 for supplying liquid a removable nozzle (Fig. 8) with the possibility of its mounting on the housing 1 at different angles. Also, the nose can carry design elements. The execution of the nozzle 10 as a separate part improves consumer qualities, does not complicate the assembly process, since it can be attached separately, simplifies the technology of changing the design of the entire product.
