PROTECTIVE DEVICE FOR FLUID IN TANK Russian patent published in 2013 - IPC B65D81/24 B65D39/02 

FIELD: packaging industry.

SUBSTANCE: invention relates to a device for storage either quality of wine or the physical properties of the fluid in the opened container. The protective device (10) can be inserted through a neck part (25) of the open bottle (26) with wine through elastic deformation, and as soon as the protective device (10) is in the bottle (26) with wine, it unfolds coming into the operational state, when its outer circumferential edge (15, 62) is located adjacent or against the inner surface of the bottle (26) with wine, floating on the surface of the wine inside the bottle (26). The protective device (10) is either a composite structure comprising a first flexible sheet material (11, 19) in the first section (14) which contains a plurality of separate sealed spaces (22), each of which has a volume and at least a part of these spaces comprises gas, and a second flexible sheet material (12, 19), at that one or both of the first or second flexible sheet materials have radial outer edge (15) forming a circumferential edge of the protective device (10) extending beyond the first section (14) in the radial direction, or a continuous sheet member (60) consisting of cork or a cork-based material, such as bonded granulated cork, at that the protective device (10) is substantially impermeable to wine and gases. A device (27, 30) is also disclosed for insertion of the protective device (10) in the bottle (26) with wine, comprising an outer flexible container (27) which is open or capable of opening at least on the section of two opposing edges (28, 29), a feeding element (30) capable to adhere to the protective device (10) and enabling to roll it around it inside the outer flexible container (27), and then to insert the folded protective device (10) through the neck part (25) of the wine bottle, leaving beyond one of the said edges (28, 29) of the outer flexible element (27).

EFFECT: development of the device for storage either quality of wine or the physical properties of the fluid in the opened container.
