Abstract
A flexible cord-like hollow object for the transportation of media is provided with an inner zone enclosed by a casing. A barrier layer, which is impermeable to volatile molecules of the medium to be transported, is provided on the casing surface facing the inner zone. The barrier layer comprises sub-elements that are arranged in a scale-like manner.
Claims12
A flexible cord-like hollow object comprising a casing (12) extending along a longitudinal axis and having (1) an inner layer (18) with an inner surface (16) encircling an inner zone for the transportation of a medium having volatile molecules and (2) a barrier layer (26), which is impermeable to said volatile molecules of the medium that is to be transported, characterized by the feature that said barrier layer (26) (i) is on said inner surface (16), (ii) comprises sub-elements (30) that are arranged in a scale-like manner and overlap in both the transportation direction of the medium and coaxially relative to said longitudinal axis and (iii) is a metal or synthetic material affixed to said inner surface by vapor deposition.
A method for preventing excessive permeation of fluid flowing through an inner zone (14) or passageway of a flexible hollow object (10), said inner zone extending along an axis, said hollow object having an inner layer (18) with an inner surface (16) and an outer layer (22) comprising the steps of
- (a) positioning a barrier layer (26) on said inner surface (16) by vapor deposition, said barrier layer (26) having sub-elements (30);
- (b) causing said sub-elements (30) to be positioned in overlapping relationship relative to adjacent sub-elements and to overlap co-axially relative to said axis;
- and
- (c) directing the flow of said fluid through said inner zone (14) in the direction of overlapping.
A flexible cord-like hollow object comprising a casing (12) extending along a longitudinal axis and having (1) an inner layer (18) with an inner surface (16) encircling an inner zone for the transportation of a medium having volatile molecules and (2) a barrier layer (26), which is impermeable to said volatile molecules of the medium that is to be transported, characterized by the feature that said barrier layer (26) is on said inner surface (16) and comprises sub-elements (30) that are arranged in a scale-like manner and overlap in both the transportation direction of the medium and coaxially relative to said longitudinal axis and further characterized by the feature that said barrier layer (26) is a metal or synthetic material affixed to said inner surface by vapor deposition.
