Jay Attorney, Agent or FirmInternational ClassB65D 47/06 (20060101)AbstractA molded plastic cap for a bottle of ammonium hydroxide includes a pair of flexible tubing sections which pass through the cap and allow the bottle to be connected to a pair of fluid conduits for a vapor-type diazo development machine. The first tubing connector has an extension into the bottle which terminates adjacent to the bottom wall of the bottle. Both of the tubing sections are adapted to be retained in a bent, collapsed position, by a notched retainer formed on the cap, to close off the tubing connectors. A projection on the second tubing section, which overlies the first tubing section when both are in a collapsed position, assures that the second tube will be opened first, to prevent pressure which may have built up in the container while it was in a sealed condition from forcing liquid out of the second section. | |
