Abstract: 1. The liquid-tight container comprises a valve arranged inside the container and formed between two elastic sheets (2, 3) directed from one edge of the container to the other and joined together along two non convergent connection lines (7, 8), enabling to form a channel (10) between the elastic sheets (2, 3) at separating from each other characterized in that two non convergent connection lines (7, 8) directed from one edge of the container to the other; a portion of one (2) of sheets arranged between two non convergent lines (7, 8) is fastened to a tongue (5) provided in the adjacent wall (1) of the container and welded to this wall by one end, while the other end is free and forms a means for catching; the liquid tight connection between the sheet (2) and the adjacent wall (1) of the container is directed around the tongue periphery (5) wherein by pulling the tongue the wall of a conduit (10) formed by the sheet (2) is torn open, and the channel communicates with the outside; a cut-out (9a) is made, at least, through one of sheets (2, 3) between non convergent connection lines (7, 8), wherein the cut-out is separated from the portion of the sheet, which fastened to the tongue (5) and intended for the channel introduction to communicate with the inside of the container. 2. The liquid-tight container of Claim 1, characterized in that a portion of the tongue (5) welded to the wall (1) of the containers arranged near welded seam (14c, 33), connecting two walls (1, 4; 1, 34) of the container. 3. The liquid-tight container of Claim 1, characterized in that the channel (10), formed by the connection lines (7, 8) comprises a widened portion, arranged near the channel end, the wall portion of which represents as one piece with the tongue (5), wherein the widened portion is made enabling to dispose in it a folded end (17a) of a distribution conduit (17) for discharging the fluid from the container, and the end of the widened portion serves as a support to prevent penetration of the distribution conduit into the channel for the depth longer, than predetermined. 4. The liquid-tight container of Claim 1 characterized in that a band (18) of material, more rigid, than the walls (1, 4) of the container fastened to it and, being as one piece with the external surface of the tongue, serves for opening the channel (10) when the band (18) is separated from the container. 5. The liquid-tight container of Claim 1, characterized in that a band (18) of material is provided with cut-in lines (19), arranged so as after the bending the band forms into a conduit for its penetration into the channel (10), opening of the valve for the liquid in the container to pass through it. 6. The liquid-tight container of Claim 1, characterized in that non convergent connection lines (7, 8), directed parallel to one of its edges, join together two opposite edges (14a, 14c). 7. The liquid-tight container of Claim 1, characterized in that a second channel (20) is formed between elastic sheets (2, 3) and its external end is disposed near one edge of the container and the other end communicates with the external portion of the container. 8. The liquid-tight container of Claim 1 characterized in that two corresponding ends of the channels (10, 20) come out to one edge of the container and arranged next to each other. 9. The liquid-tight container of Claim 7, characterized in that a cross section of the conduit (10') near its end, opposite to the cut-out (9'a) has a narrowing, the cross section of which corresponds essentially to the cross section of the distribution conduit (17'). 10. The liquid-tight container of Claim 9, characterized in that the narrowing of the cross section of the conduit (10') constitutes a support for interacting with the corresponding support (17'a), made as one piece with the distribution conduit (17'). 11. The liquid-tight container of Claim 7, characterized in that two elastic sheets (2, 3), joined together along two non convergent lines (7, 8) are connected to one of walls (1, 4) of the container, at least, in two points (41), arranged by one along each side of the conduit (10, 10'). 12. Process for conditioning a liquid in the container of Claim 7, characterized in that the container is formed with two conduits (10, 20), at least one outer end of the second conduit (20) is left open and the fluid is poured through the second conduit (20), and the outer end of the second conduit (20) is closed tight. 13. Process for conditioning a liquid in the container of Claim 12 characterized in that a layer of protecting varnish (6a) is applied between the edges of the elastic sheets (2, 3) corresponding, at least, to the outer aperture of the second channel (20) near the container edge, wherein the width of this layer (6a) is less than the width of the welded seam (14a), forming the container edge and the container edge is welded, reducing the width of the welded seam in a point, corresponding to the aperture of the second conduit near the container edge and overlapping this welded seam of the reduced width; the container is filled through the second conduit (20) and a side welded seam is formed near the varnish protecting layer (6a) between two edges of the narrowing on the portion of the welded seam width (14a) of the container edge left free from the vanish protecting layer (6a)near the outer aperture of the second conduit (20). 14. Process for conditioning a liquid in the container of Claim 12 characterized in that a layer of protecting varnish (6a) is applied between the edges of the elastic sheets (2, 3) corresponding to location of other end of the first conduit (10) coinciding with one container edge opposite the end where the elastic sheets (2, 3) are cut (9) between non convergent lines (7, 8), wherein the width of this layer (6a) is less than the width of the welded seam (14a), forming the container edge, and the container edge is welded, reducing the width of the welded seam in a point, corresponding to the other end of the conduit (10) to the edge of the varnish protecting layer (6a) overlapping this welded seam of the reduced width; introduce a tubular element into the conduit (10) and bend it back so as not to reach the point, where the sheets (2, 3) are cut between non convergent lines (7, 8) and form a side welded seam next to the varnish protecting layer (6a). 15. Method for using a liquid tight container of 3 and 7 Claims, characterized in that the tubular element (17) for discharging of the liquid from the container is introduced into the channel (10), the portion of the tubular element, arranged outside relative to this channel, is bent out, the end of that bent portion (17a) is pushed against the widened portion of the channel to prevent penetration of the distribution conduit into the channel for the depth longer, than predetermined.
