Patent ID: 7185793

Claim:
A closing device for recipients in the form of a flask or tube, made of a preferably flexible material and which is provided with a nozzle covered by a cap axially locked in the recipient, in order to be selectively angularly displaced around its axis, comprising: a seat in the form of a cylindrical housing provided in the nozzle and having an outwardly opened free end, and at least one radial window defining the single communication between the interior of the seat and the interior of the recipient; a cylindrical tubular seal axially affixed in the interior of the cap having at least one radial opening and being fitted and journalled in the interior of the seat; and a sealing means, incorporated into the interior of the cap and which is seated against the free end of the seat to seal it, said cap having an axial through orifice, opened to the interior of the cylindrical tubular seal and being selectively angularly displaced, around its axis, between an opening position, in which there occurs the alignment between the radial window and the radial opening, as well as the communication between the interior of the recipient and the axial orifice of the cap, and a closing position, in which the radial opening is offset from the radial window, blocking the communication between the interior of the recipient and the interior of the cylindrical tubular seal.
