Abstract:
1. A packaging with a hermetically sealed dosing mechanism for semi-solid products comprising: (1) a body, having: (2) an over-lid having a skirt with internal side having a continuous smooth coupling groove; (3) a spinning disc, having a horizontal upper wall and a vertical cylindrical outer skirt, said cylindrical outer skirt having a bottom edge projected outwards in the shape of a flange with a diameter constructed and arranged to lay on said horizontal wall; and having smooth locking fillets, constructed and arranged to receive the over-lid; and having a concentric cylindrical lip in the shape of a circular guide, with a diameter that is constructed and arranged to penetrate with interference in the void and to be tensioned over the cut, said disc configured so that said bottom edge applies pressure on said circular closing ring, allowing an hermetic coupling of the spinning disc; and having a collar of flexible equidistant tabs, slightly bent and constructed and arranged to slide on a carriage formed by teeth, constructed and arranged to enable a sliding movement in only one direction; a collar of coupling projections with a trapezoidal transversal section dimensioned and oriented to be inserted in the groove so as to enable a sliding coupling for the spinning disc, in a way that said disc is kept permanently over pressured against the skirt, as well as being turned in only one direction, and in the same plane in relation to the skirt to secure sealing; and (4) an integrated internal assembly comprising an actioning mechanism, a piston placed along with the bottom of the cup-like recipient, and a protective dosing valve, wherein, the sliding movement actioning the mechanism actuates the piston, the spinning of said piston being avoided by the slightly oval internal diameter of the cup-like recipient; said piston being operatively assembled to be displaced only upwards upon activating the spinning disc and the mechanism, so that said piston applies sufficient pressure to the product placed above said piston in said cup-like recipient, opening the protective dosing valve and allowing exact dosages of the product to be dispensed above said spinning disc onto the surface, from where the product is removed by a user.
