Abstract
An inflation valve for inflating containers with non-rigid walls comprising a tubular body defining a passage with a first opening at one end and a second opening at its opposite end, adapted to be secured to a container; a sealing disc adapted to sealingly close off the second opening to the passage in the tubular body, and adapted to open the second opening mechanically when an inflation device is inserted into the passage through the first opening and thus gas may be passed into the container through the second opening, thereby moving the sealing disc away from the second opening; a guide member located within the passage of the tubular body; a spring adapted to assist the sealing disc to close off the second opening; and a gasket and/or sealing ring adapted to assist the sealing disc to close off the second opening.
Claims28
An inflation valve comprising:
- (a) a tubular body defining a passage with a first opening at one end leading into the passage and a second opening at its opposite end leading into the passage, the tubular body configured to be secured to a container having non-rigid walls;
- (b) a plastic plunger configured to sealingly close off the second opening to the passage in the tubular body, and the plunger configured to open the second opening mechanically when an inflation device is inserted into the passage through the first opening to facilitate gas flowing into the container through the second opening and thereby moving the plunger away from the second opening;
- (c) a guide member located within the passage of the tubular body;
- (d) a spring associated with the plunger and supported by the guide member, the spring configured to assist the plunger to close off the second opening;
