Abstract
The device comprises a chamber 9 having an outer wall 10 and an inner wall 12 which separates it from the container, the chamber 9 communicating with the exterior through at least one orifice 16, 16a, 16b, 16c in the outer wall 10 and with the interior of the container through a tube 13 which extends through the inner wall 12 and projects into the chamber 9. The shape of the inner wall 12 and the position of the orifice 16, 16a, 16b, 16c being such that, in any position of the container, the orifice, or a part of the orifice, is located at a level lower than the level of the inner end 15 of the tube 13 so that any liquid which may be contained in the chamber cannot penetrate into the container.
Claims16
A pressure balancing device which is watertight as concerns rainwater or trickling water for combination with a transporting container for transporting for example fragile articles, said device comprising a chamber having an outer wall and an inner wall which is for separating said chamber from said container, at least one orifice in said outer wall for putting said chamber in communication with the exterior, a tube extending through said inner wall and projecting into said chamber for putting the interior of said chamber in communication with the interior of said container, said inner wall having such shape and said orifice having such position that, in any position of the container, at least a part of said orifice is located at a level lower than a level of the end of said tube in said chamber.
An enclosure in combination with a pressure balancing device which is watertight as concerns rainwater or trickling water, said device comprising a chamber having an outer wall and an inner wall, which inner wall separates said chamber from the interior of said enclosure, at least one orifice in said outer wall for putting said chamber in communication with the exterior, a tube extending through said inner wall and projecting into said chamber for putting the interior of said chamber in communication with the interior of said enclosure, said inner wall having such shape and said orifice having such position that, in any position of said enclosure, at least a part of said orifice is located at a level lower than a level of the end of said tube in said chamber.
