Description

The utility model relates to devices for storing, transporting and dispensing liquid in a container under pressure and can be used to store and dispense drinks from kegs and bottles made from polyethylene terephthalate and intended for automated bottling.

Tanks with valve structures (fittings) installed on them are used to store and dispense drinks, such as beer. To push beer out of the keg, it is necessary to create excess pressure in it. To do this, gas is supplied to the keg with the drink, as a rule, it is carbon dioxide (sometimes nitrogen, inert gas or air). Typically, in the case of beer, the overpressure is about 2.5-3.5 bar. The indicated pressure is the operating pressure of the vessel. When assembling the container, it is necessary to control the applied twisting force of the fitting in order to ensure the tightness of the structure.

Fittings have several channels for the passage of liquid and gas. When filling, if the container is upside down, the beverage is introduced through the first channel of the valve structure, while the gas displaced from the container exits through the second channel. If the container is filled in the normal position (fitting up), and also during filling, gas (nitrogen or carbon dioxide) is introduced into the container through the first channel in order to displace the beverage from the container through the second channel. The bottling of the drink is carried out under the influence of the dosing head, attached to the valve structure on the spring-loaded elements of the valve structure with the subsequent opening of the channels, one of which is designed to supply inert gas under excessive pressure, and the second channel to dispense the gas displaced beverage.

When disassembling the device, safety precautions should also be observed when bleeding off excess pressure.

A container with a fitting contains a container and a threaded fitting.

The tank includes a bottom, a base, a shoulder part and a neck 1 with a thread. In the lower part of the neck 1 (Fig. 1, a, b, c) there is a radially located skirt 2 on which at least one retaining stop 3 is located with an angle of inclination to the central axis of 10 ° (Fig. 1, b). The shape of the stopper 3 (Fig. 1, a) is a rectangular trapezoid with an angle of 10 ° at its base, while the location and length of its base are determined experimentally and corresponds to the maximum force required to seal the container.

On the neck 1 of the container, a fitting 4 is fastened with a thread, comprising a cap 5 made in the form of a fungus with a central hole, a hollow rod 6, a valve element 7, a spring 8 and an annular nut 9, which provides its compression, installed along it along the longitudinal axis (Fig. 2).

The cover 5 consists of a base 10, which can be made both in the form of a circle (Fig. 3a, b), and in the form of a truncated equilateral triangle, the vertices of which are bounded by a circle (Fig. 4), equipped with a side 11 and a cylindrical leg 12. On the junction of the base 10 and the outer annular surface of the rim 11 made ribs 24.

An internal thread 13 is made on the side 11. To ensure the manufacturability of the structure twisting on the neck of the threaded container, the lid surface can be provided with protrusions 14.

Also, at least one locking groove 15 (Fig. 3, 4) is made on the edge 11, designed to control the quality of the capping, as well as to control unauthorized removal of the fitting. The shape and dimensions of the locking groove 15 correspond to the dimensions of the locking stop 3 on the neck of the container.

The cover 5 (Fig. 2) is provided with a central hole with an annular protrusion 16, interacting with the annular ledge 17 of the valve element 7. To ensure a tight connection between the fitting and the neck of the container between the cylindrical leg of the fungus 12 and the edge 11 of the cover 5, an annular gasket 18 with a circular cross section is placed .

The rod 6 is made hollow in the form of a tube. One end of the rod is made open and passes through the hole of the ring nut 9, protruding beyond it. The second end of the rod 6 is closed and provided with a protrusion 19. In the upper part of the hollow rod 2 is placed at least one window 20.

On the stem 6, with the possibility of movement along it, a valve element 7 is installed with a central hole provided with an annular ledge 21, configured to interact with the protrusion 19 of the hollow rod 6. A vertical tube is installed at the open end of the rod.

The compression of the valve element 7 to the annular protrusion 16 of the cover 5 is carried out by a spring 8 installed between the ring nut 9 and the valve element 7. To prevent the surface of the material of the valve element 7 from being pressed through, a sealing ring 22 is installed between it and the spring 8.

Fastening the ring nut 9 to the cover 5 is a threaded connection. The ring nut 9 is provided with centering tabs 23, as well as holes for the passage of liquid or gas.

Utility Model Implementation

The container is made of polymeric materials, in particular polyethylene terephthalate (PET). For the manufacture of the fitting, polymeric materials are used, in particular, the cap, stem and ring nut of the fitting are made of polyacetal, and the valve element is made of silicone rubber.

For the manufacture of a tube for dispensing a beverage, polypropylene or polyethylene is used.

The shape of the stopper 3 and the stopper groove 15 is a rectangular trapezoid with an angle at the base of 10 ° and a base length corresponding to the maximum force required to seal the container. So, the optimal capping force is 15-20 N / m, which allows for tight assembly.

The base length of the rectangular trapezoid corresponding to a closure force of 20 N / m is 23 ± 2 mm.

The assembly of the device is as follows:

A valve element 7 is mounted in the central hole of the cover 5 of fitting 4, and a hollow stem 6 is mounted on the valve’s central hole, onto which the sealing ring 22 and spring 8 are mounted. A gasket 18 is installed at the border of the flange 11 and the cylindrical leg 12 of the cover 5, after which the assembled structure connected by a threaded connection with a ring nut 9. To the open end of the hollow rod 6 is attached a pipe for dispensing a beverage and thus assembled fitting 4 with a pipe for dispensing ka 1 is mounted on the neck of the container threaded connection. At the same time, when the minimum required closing force of 15 N / m is reached, the edge of the stopper stop 3 of the neck 1 engages with the stopper groove 15 on the collar 11 of the fitting 4, and when the maximum necessary force of the closure is reached, the stopper 3 of the neck 1 fully engages with the stopper groove 15.

Tank filling is carried out as follows:

The filling head of the automatic filling line (not shown in Fig.) Has one or more protrusions that press on the surface of the spring-loaded valve element 7 open from the side of the cover 5. In this case, the first annular channel opens between the valve element 7 and the cylindrical leg 12, and the second channel formed by the internal channel of the hollow rod 6 with an open window 20 on its generatrix surface. Filling the tank with liquid is carried out through the second channel, while the gas in the tank is displaced through 1 channel. After relieving the pressure from the side of the casting head to the valve element 7, it returns to its original position, blocking the channels. Storage and transportation of the container filled with the drink is carried out with the valve element 7 closed.

The liquid is dispensed from the container in the opposite way: The protrusions of the dosing head (not shown in Fig.) Press the surface of the spring-loaded valve element 7 open from the side of the cover 5. This opens the first annular channel between the valve element 7 and the cylindrical leg 12, as well as the second a channel formed by at least one window 20 on the forming surface of the hollow rod 6. An inert gas is supplied to the container through the first annular channel under excessive pressure from the external container, which extrudes yaet liquid located within the vessel through a tube attached thereto hollow rod 6 and the window 20 on the envelope surface of the hollow stem 6.

Benefits:

manufacturability by providing the possibility of a separate assembly of valve structure elements, installing it assembled on the tank and then filling the tank on an automatic production line;

ensuring reliability and tightness of the product through the use of a threaded connection of the cover and the ring nut, sealing the neck of the container at its end when connecting to the valve structure;

the possibility of visual control of the quality of capping;

ensuring the reliability of capping that prevents unauthorized removal of the fitting. The engaged locking step on the neck and locking groove on the fitting will complicate the process of removing the fitting. The unscrewing force of the fitting is more than 22 N / m and without special devices it is impossible to unscrew the fitting. If the fitting is removed from the container, damage to the stopper of the neck of the container will be visually visible.
