Description

The utility model relates to containers for liquid products, namely, vessels filled mainly with liquid materials and can be used in food, chemical, pharmaceutical, perfumery and other industries and also suitable for use in discharged space at high altitudes, in outer space.

Known vessel shutter which consists of a glass with spiral flanges on the outer surface and the cap located on it. See USSR patent No. 212888, publ. 1968

The known vessel is not convenient enough for use, since the glass is fixed using the internal thread of the cap, which also has an o-ring, and when removing the glass, the operator must hold the glass with his hand and hold it, while rotating the cap. Also known is a vessel for a liquid in which the inner surface of the wall of the glass is conical with a smaller base adjacent to the upper part of the neck.

In addition, on the end surface of the cap mounted inwardly curved legs to interact with the spiral beads of the glass and prevent it from bending.

See USSR patent No. 580818 publ. 11/15/77 Bul. Number 42.

This vessel is complex in design and inconvenient in operation, which does not allow to achieve a technical result created by the proposed utility model.

Known capacity containing the nose and neck. A disadvantage of the known capacity is the inconvenience of metered consumption of material requiring multiple tilt of the vessel. See the description of the invention to A.S. USSR No. 1009914 publ. 04/07/83, Byul. No. 13.

Known containers also containing a spout and a neck have similar disadvantages. See the book Resurrection P.I. The technique of laboratory work. M. "Chemistry", p. 79, Fig. 95, 96.

Known vessel for drinks suitable for use in outer space which contains a rigid outer shell with a hole for passage of drinks into and out of the vessel, an elastic container and a spring.

The spring is located between the end wall of the elastic tank and the bottom of the rigid outer shell.

When draining the stiffness, the cork located in the neck is opened and an elastic container squeezes the liquid out with a spring.

The elastic container can be made of an inelastic material, and then for the liquid, gas injected under pressure into the space between the rigid outer shell and the elastic container can be used as a pressure source.

The elastic container can be made corrugated. Moving it to the closed position is carried out by means of a spring.

This vessel is taken as the closest analogue to the "prototype". See the description of the invention to the patent of the USSR No. 1443793 publ. 12/7/88, Bull. No. 45.

The prototype has the following disadvantages that do not allow to achieve a technical result created by the proposed utility model:

- structural complexity due to the presence of a rigid outer shell, elastic capacity, spring creating pressure on the elastic capacity;

- free access to contents after uncorking, which reduces reliability;

- difficulty in manufacturing, since after injecting gas into the space between the rigid outer shell and the elastic container, it is necessary to create a tight connection without releasing gas;

- after opening the vessel and once receiving the contents, there is no way to seal the container and keep the remaining contents for a long time.

The task and the technical result are to eliminate these shortcomings, simplify the design and manufacture, increase the reliability of ease of use and ensure the safety of the liquid for a long time.

This is achieved by new technical solutions that are in a causal relationship with the technical result.

The essence of the claimed device is expressed in the aggregate of the following essential features.

In a plastic vessel for a liquid that contains a corrugated container and a neck with a stopper, the distinguishing features from the prototype are the signs - the presence of a check valve, a stop rod with a spring with the possibility of interaction with a check valve. The thrust rod is fixed in the tube motionless and contains side and axial holes.

The above set of features in comparison with the prior art allows us to conclude that the proposed technical solution meets the criterion of "novelty."

Figure 1 - the proposed vessel in the context, schematically.

The proposed vessel consists of a corrugated plastic container 1, which can be compressed and expanded due to the corrugations under the influence of effort.

A stopper 3 is screwed on the neck 2. A stopper 4 is fixedly fixed in the stopper 3 which contains side holes 5 and a through axial hole 6. A spring 7 is put on the stopper 4. The presence of these parts explains the structural simplification of the vessel and the simplification of its manufacture as a technical result.

In the cover 8, a socket hole 9 is made in which a check valve 10 is installed, preloaded by a spring 7.

This achieved a technical result consisting in ease of use and ensuring the safety of the liquid 11 located inside the tank 1 without cooling it.

A plastic vessel for a liquid, for example, a bottle (hereinafter referred to as a vessel) works as follows.

The stopper is unscrewed by 180 °, thereby releasing the shut-off valve 10 from the action of the stop rod 4, after which only the spring 7 is pressed against the socket opening 9.

The liquid is poured through the holes 5, the through hole 6 in the thrust rod 4 and the nozzle 12.

As the compression of the vessel ceases, the valve 10, under the action of the spring 7, closes the socket opening 9, thereby preventing the formation of any superficial space. Air does not enter the vessel during fluid withdrawal.

If necessary, save the remaining liquid for a long time, as a technical result, the plug 3 is wrapped to the end. The thrust rod 4 still presses the check valve 10 against the socket hole 9.

The proposed plastic vessel for liquid is made and tested as a prototype. The vessel can be manufactured industrially on automatic lines. Design documentation has been developed.
