Intended for containers whose structure consists of a tubular body (1) to which is joined a piston (2) which in turn is joined to a stick or handle (4) and includes a revolving platform (5) fed by said container components and having in its circumference a number of operative units which each are made up of a rod (22) resting through a roller (17) on a lower fixed cam (15) and which can be retracted against the pull of a spring (20), this rod (22) being associated to a mobile bushing (24) which, like the rod (22), in its upward motion can pass through the revolving platform (5) to carry up the tubular body (1) and the corresponding piston (2), thus moving them towards the corresponding stick (4) placed in an upper retainer (12), causing the union of the stick to the piston and the penetration of the latter in the opening of the tubular body. |
