The method of dispensing liquid and pasty products into a container involves draining the container simultaneously with its outer and inner sides, feeding the product into the container and communicating it with the atmosphere from the side of the container's mouth.

FIG. 1 shows the dispenser with container, general view; in fig. 2 - the process of introducing containers and a vacuum chamber; Fig. 3 shows the process of filling a container with a product; in fig. 4 - the process of removal of the vacuum chamber from the tank and the air intake; LF FIG. 5 shows the process of removing filled containers.

The dispenser for liquid and pasty products contains a reservoir 1, at the bottom of which there is an outlet conic opening 2, a valve 3 with a stem 4 and a vacuum system. The vacuum system includes a detachable chamber located below the outlet 2 of the tank 1 with the possibility of reciprocating vertical movement of the container 5. The separable chamber consists of a container b for the container and a housing 7. In the upper part of the latter there is a tapered bore 8. On the housing 7 There is a port 9 for connection to a vacuum source.

The method is carried out as follows.

In the initial position, the outlet 2 is closed by the valve 3. The tank 1 is filled with a product, for example, Sanita paste. The container 5 is placed on the table 6. Then the table 6 is raised to contact with the court is stopped by returning the valve to its original position. When the chamber is discharged down through the gap formed, air rushes at high speed into the chamber at the neck of the container 5. Air jets pick up 2 drops formed at the lower edge of the opening and drop them into the container 5. Then the table b is removed and the container 5 is removed. 2 sec. n. f-ly, 5 ill.

with the start 7, wherein the container 5 is placed in a detachable chamber. Thereafter, the detachable chamber rises until it stops at the bottom of the tank 1. The conical holes 2 and 8

are aligned, and the holes 8 are also blocked by the valve 3.

Air is sucked out of the detachable chamber through the pipe 9, as a result of which the container is evacuated simultaneously from its outer and inner sides. After that, by means of the stem 4, the valve 3 is retracted upwards, opening the openings 2 and 8. Air presses on the product in the tank 1 and as a result of

pressures the product fills the container 5. At the end of the filling of the container, the valve 3 closes the openings 2 and 8 and the supply of the product stops.

A detachable chamber is diverted from reservoir 1, opening aperture 8 and forming a slit through which atmospheric air rushes at great speed into the detachable chamber from the mouth of the container 5. Air jets pick up 2 drops formed at the lower edge of the container and discard them into the container 5.

Then the table was retracted from the chamber and the container 5 filled with the product was removed. Then the cycle repeats.

The proposed method of dosing

liquid and pasty products and a device for its implementation - the dosing unit for liquid and pasty products ensures the filling of the product in a soft

the container simplifies the process of packing and is more efficient in the process of operation.

Claims (2)

1. A method for dispensing liquid and pasty products into a container, which involves evacuating the container, feeding the product into it and communicating the container with the atmosphere, characterized in that, in order to expand the technological capabilities by ensuring that the product is packaged in both rigid and soft containers while removing the packaging droplets, the evacuation of the container is performed by placing the container in the chamber with means for communication with the vacuum system, and the container is connected with the atmosphere from the side of its neck. 2. A dispenser for liquid and pasty products, comprising a reservoir for a product with an outlet, a valve and a vacuum system, characterized in that, in order to expand the technological FIG. 2 opportunities by providing packing of the product in both rigid and soft containers with simultaneous removal of droplets formed during packing, the vacuum system includes a detachable chamber located under the outlet of the reservoir with the possibility of reciprocating movement in a vertical plane made conical hole. | BP1 air 7 (vacuum) Fig.Z Yoeduh inlet fig.Ch
