Description

FIELD OF TECHNOLOGY TO WHICH THE UTILITY MODEL RELATES

The utility model relates to devices for food processing, namely devices for vacuum sealing and designed to create a vacuum in containers and seal them in order to preserve food products, mainly for home canning of food products. Other applications for this vacuum pump are possible.

BACKGROUND OF THE INVENTION

Known manual vacuum pump containing a cylinder, inside which is installed a piston rod and a cuff, and a hole on the working end of the cylinder, while on the outer surface of the cylinder is made convex influx; the cylinder is made of plastic, the cylinder is made of aluminum (Description of the utility model to the patent of the Russian Federation No. 177355, IPC B67D 7/00, published on February 16, 2018).

The difference of the proposed technical solution is the lack of reliability.

A device for vacuum sealing with a lid of a glass jar-type container is known, containing a bell-shaped housing, the inner cavity of which forms a vacuum chamber covering the neck of the can, connected to the vacuum chamber housing, coaxial with it, connected to the vacuum chamber by an air channel, a pump housing made in the form cylinder with a hollow rod located in it, the outer end of which is provided with an outlet and a handle, and the inner end with a piston, a drain valve installed in the air channel connecting the vacuum chamber with the pump, and an outlet valve installed in the pump (Description of the invention to the patent of the Russian Federation No. 2 103 222, IPC B67D 3/24, published 01/27/1998).

The proposed technical solution is quite complex, requiring adjustment of the mechanism, difficult to manufacture.

As the closest analogue - prototype, a device for vacuum sealing with a lid of a glass jar type container is selected, containing a body, the inner part of which is made in the form of a cylinder with an open lower end and a closed upper end with a hole in which the rod is located, the upper outer end of the rod is provided with a handle, and a cuff is fixed at the other end of the rod, while the lower part of the cylinder, located at the open end, is made expanded, with a diameter equal to or less (in the range of 0.97-1.0) of the outer diameter of the cuff part adjacent to the surface of the cylinder and with a smooth transition to the main part of the cylinder, for example, in the form of a cone; the edge of the outer expanded part of the cuff is provided with a shoulder, for example, of a rounded shape in cross section (Description of the utility model to the patent of the Russian Federation No. 41718, IPC V67V 3/24, published on 10.11.2004).

The difference of the proposed technical solution is the lack of reliability, since it is not possible to quickly disassemble the pump to replace the cuff at the end of its service life.

IMPLEMENTATION OF UTILITY MODEL

Vacuum pump for capping food containers includes:

1 - body;

2 - stock;

3 - T-shaped handle, decoratively made in the form of a flower;

4 - plug;

5 - ring;

6 - lock connection;

7 - lower part from the outer side of the body;

8 - lower part from the inside of the case;

9 - sealant;

10 - round partitions;

11 - technological ribs;

12 - the outer side of the partitions;

13 - the inner side of the partitions - cone-shaped;

14 - the inner side of the partitions - rectangular;

15 - mounting groove;

16 - slots of the partition from the side of the lock connection.

The essence of the proposed technical solution is that the vacuum pump for capping containers for food products contains a housing 1, having an elongated cylindrical shape, with an open lower end and a closed upper end and a hole in which the rod 2 is located, the upper outer end of the rod is provided with a handle T -shaped form 3decoratively executed in the form of a flower. A decorative cap 4 is installed in the upper part of the handle. A sealing ring 5 is fixed at the other end of the stem.

The handle is decoratively made in the shape of a flower. The lock connection 6 fixing the handle is made in the upper part of the rod in the form of hooks - cone-shaped protrusions with an extension to the bottom (Fig. 1, 2, 3 and 4). The cone-shaped protrusions of the interlock can be made at an angle φto the end of the cover from 10 to 30° (Fig. 8). A decorative cap also serves as a stop, preventing the hooks from arbitrarily detaching when applying great efforts.

The lower part of the body is widened and shortened on the outer side 7 for a more stable and snug fit to the lid, narrowed and elongated on the inner side 8 (Fig. 4).

A removable seal 9 is also installed on the housing cylinder, which is necessary for tighter contact between the pump and the cover. This allows you to select a seal with the desired sealing profile suitable for any type of vacuum closure. A seal for the lids of the Wax system is presented (Fig. 2, 4).

On the lower outer part of the rod, two round partitions 10 are made, which form a seat (installation groove) for the sealing ring. Between the partitions there are technological ribs 11, which reduce the play of the sealing ring on the piston. Partitions on the rod from the outside can be made rectangular and rounded 12, and on the inside - conical 13 or rectangular 14. The ring is not fixed tightly and has a small play inside the mounting groove 15 (Fig. 4, 5, 6, 7, 8 and 9).

The partition on the side of the lock connection has slots 16 for air to escape when the rod moves down (Fig. 5 and 7).

The ring can simultaneously perform the functions of a seal and a valve. When the rod moves up, sealing occurs. When the rod moves down, it passes air along the inner diameter of the ring and the slot in the partition (Fig. 5).

The ring is made of an elastic material, in particular rubber, silicone or plastic.

Requirements for materials are standard - safe for human health. In addition, they must repeatedly withstand device sterilization processes before use.

A vacuum pump is used to seal containers for food products in the following way.

A seal is inserted tightly into the recess of the lid with a valve placed on the jar (not shown in the drawing as not reflecting the essence of the proposal) when the device is pressed against the lid. At the same time, pressing the body on the lid ensures a snug fit of the device to the lid, and the lids to the jar. Pulling the stem with the handle creates a vacuum in the jar, which allows atmospheric pressure to press the lid tightly against the edges of the jar. The intake of air from the outside is blocked, due to which a vacuum will be created inside the case and gas from the can through the lid rushes into the case.

When the stem moves upward, air from the upper part of the body above the ring exits between the surfaces of the stem and the upper hole of the body, and air from the can enters the lower part of the body under the ring through the lid valve. When the stem moves down, the bonnet valve closes, and the remaining air in the lower part of the body passes into the upper part of the body between the ring and the surface of the body. To create a deeper vacuum, the pumping of air is continued. The number of movements depends on the filling of the can with the product and the amount of air remaining in the can. The pump allows you to create a vacuum up to 95%. With spontaneous return of the rod down to the stop, the pumping of air is stopped. After the end of the canning process, the rod is brought to the lower position, the ring in the lower part of the body is straightened and the stress of its material is relieved, the ring acts as a seal. This position of the stem ensures that the elastic properties of the ring material are maintained between canning processes.

The claimed device meets the patentability criteria "novelty", and can be implemented industrially in mass production. The device can be used repeatedly (at least 200 times). The duration of operation is determined by the elastic properties of the materials from which the ring and seal are made.

Thus, in the vacuum pump for capping containers for food products, the maintainability has been increased by adding a special locking connection on the stem, which will allow the pump to be disassembled to replace the ring, which increases the service life of the product, ensures reliability and quality.
