SU1443793A3 - Vessel for beverage fit for use in space - Google Patents

Abstract

The invention relates to a beverage container which may be used in space. The container comprises a rigid outer casing 12 into which is placed a chamber 14 intended to contain the beverage and which dilates upon introduction of the fluid and then flattens to a negligible volume on dispensing of the beverage; the chamber may be an elastic bag 14, a flexible bag surrounded by a compressible gas, a container of the concertina type or, alternatively, a tube comprising a tail part which can be rolled up on itself to a negligible volume through the effect of the elastic properties of the material from which it is formed.

Description

114A3793

The invention relates to containers for liquid products and can be used as a vessel for the same

vessel or its emptying and it can be opened, for example, by means of straws.

beetles suitable for use in outer space,

The purpose of the invention is to increase the convenience of operation.

FIG. 1 shows the proposed vessel, a general view of} in FIG. 2 -

the same as the pressure source. gas is used, in FIG. 3 - the same, the embodiment; in fig. 4 - the same as a spring is used as the pressure source.

The vessel consists of a rigid outer shell 1 with an opening 2 for the passage of the drink into and out of the vessel, an elastic mark 3 located therein with a neck connected to the opening 2 of the vessel, and a pressure source for compressing the bag to an unstretched state the pressure source can be used gas A, which is pumped into the space between the rigid outer shell 1 and the elastic bag 3, the latter can be made corrugated, conical in shape 5 with rigid end walls, and as a pressure source A spring 6 should be used, located between the end walls of the bag and the bottom of the shell 7.

The rigid outer shell 1 has an air vent 8 allowing the elastic bag 3 to expand when the liquid is introduced into it, a normally closed valve is in the neck 9 of the vessel, and the vessel can have a tube 10.

The vessel works as follows.

The vessel through the opening 2 is filled with liquid that enters the elastic bag 3. When the bag is completely filled with liquid, it is pressed against the inside walls of the rigid outer shell 1. After the liquid is completely drained from the vessel, the flexible MB. SHOCK 3 is completely collapsed.

The use of the elastic bag 3 prevents the formation of any subsurface space during the vessel filling process, and

elastic properties create effort

 For the removal of liquid from the vessel, a normally closed valve (not shown) is present at the neck 9 of the vessel. This valve is unclipped during filling.

In another embodiment of the vessel, the elastic bag is flexible, but not elastic, and the gas 4, which serves as a pressure source for emptying the vessel, ends under pressure in the inner space between the outer shell 1 and the elastic bag. As soon as the elastic bag 3 is filled with liquid to an appropriate level, the gas surrounding the bag is compressed and exerts constant pressure on the elastic bag 3 during filling, preventing the formation of a subsurface space. When opening the valve for dispensing a liquid, the compressed gas 4 expands and helps push the liquid out of the elastic bag 3.

In the third embodiment, the vessel comprises an elastic tube 10 having a rolled tail that tends to collapse, i.e. The tO handset has a memory. This tube tends to push fluid out of the interior when the valve is open.

Another embodiment of the vessel provides for making the elastic bag 3 corrugated, conical 5 and moving it to the closed position by means of the spring 6. Due to the spring action of the spring 6, the surface does not form a corrugated bag. inside the vessel during its filling with liquid. When it is necessary to pour the liquid out of the vessel, the valve opens, and the spring 6, squeezing the corrugated bag, displaces the liquid. The conical shape allows the elastic bag 3 to fully fold into concentric rings without creating a dead space in which liquid can remain.

Claims (3)

1. A beverage vessel suitable for use in outer space containing a rigid outer shell with an opening for passage and not vessel, about that 31 the purpose of increasing the convenience of operation is to provide an elastic bag with a neck located in a rigid outer shell and connected to its opening by the neck, and a pressure source for compressing the bag to an unstretched state, while the volume of the bag in an unextended state is less than the volume of the hard outer shell and the volume of the bag in the stretched state corresponds to the maximum possible volume of the drink, equal to the volume of the rigid outer shell. 2. The vessel according to claim 1, characterized in that, as used  . vvv-.i .- / and about . BUT . . J 7 . 2 437934 the pressure point uses gas injected under pressure into the space between the rigid outer shell and the elastic bfenmoH. five 3. The vessel according to claim 1, characterized in that the elastic bag is made conical in corrugated form with rigid end walls, and a spring is used as the source of pressure, located between the end wall of the elastic bag and the bottom of the rigid outer shell. ten Fi.d Fy
