<p>669,446. Double ampoules. DORIER, C., and CHIBRET, J. Nov. 14, 1949 [March 19, 1949], No. 29086/49. Class 81 (i). A container for preserving substances to be mixed at the time of their utilization comprises a bottle containing one of said substances and formed with a tube having a normally closed end on which a cylindrical stopper of compressible material and a cap member threaded with its lower end on said stopper are adapted to slide, said cap member containing the other substance, means for allowing the bottle and cap member to communicate with one another through said tube when the contents are about to be utilized, for mixing both substances, the bottle being provided with another tube or orifice for extracting the mixture. As shown, the container comprises a bottle 1 containing a solvent L and having a tube 2 integral therewith at its upper end and another tube 3 laterally of the main body of the bottle 1. The tube member 2 is provided with an orifice 4 which is normally closed by an annular stopper 5, preferably of rubber. Threaded on this stopper is a cylindrical closed cap member 6 having a restricted portion 6a and an enlarged portion 6b and containing a solid 5. The cap member is under vacuum. In use, the orifice 4 is uncovered by sliding the cap 6 and stopper 5 towards the bottle 1, the bottle is turned upside down until the solid in the cap has been dissolved by the liquid flowing from the bottle and is then put back in its original position. The ends of the tube member 3 and cap 6 are broken and the solution withdrawn through the arm 3. In a modification, Figs. 2 and 3 (not shown), the tube on which the cap and stopper slide extends downwardly to a short distance from the bottom of the bottle, the orifice is adjacent the lower end of the tube and a file mark is made on the tube at a level just above the upper end of the stopper. In use, the cap member is inclined sidewise to break the tube at the file mark, the tip of the cap and the side tube are broken and the solvent drawn into the cap by means of a rubber bulb attached to the top of the cap. Either the cap member or bottle, or both, may be under vacuum or may contain an inert gas.</p> |
