Definitions
- the present invention relates to aerosols dispenser for delivering products by means of a pressurised propellant gas.
- an aerosol dispenser of the above type which is provided with an inner flexible container for containing the product to be delivered and which can deform under the action of the propellant gas.
- the object of the invention is to produce an aerosol dispenser of the above type which, in the case of unitary pressure containers, enables the rapid and mechanised insertion of the inner container and which enables complete emptying without waste.
- the subject of the present invention is an aerosol dispenser of the type specified above, whose main characteristic lies in the fact that the inner container is helical in shape so as to enable its insertion in a unitary pressure container through the neck of the container by means of an operation analogous to screwing.
- the inner container can be fitted in a mechanised manner with the aid of a rotary spindle.
- the inner container is in the form of a hollow helical coil whilst in a second embodiment the inner container is in the form of a helical bellows.
- a unitary pressure container usable for the delivery of products by means of a pressurised propellant gas is indicated 1.
- the container 1 is provided with a neck 2 whose mouth has an aperture of the conventional diameter of one inch (2.54 mm).
- An inner flexible container of plastics, metal, or metallised material is indicated 3 and is constituted by a tube 4 of substantially-rectangular elongate cross-section which is wound into a helix so as to take the form of a hollow helical coil.
- the coil is closed at its lower end and is connected at its upper end to a connector 5 which is intended to be gripped in the mouth of the pressure container 1.
- the coil 3 communicates with the atmosphere through a delivery valve of known type, not illustrated in the drawing.
- the propellant is contained between the coiled container 3 and the inner wall of the pressure container 1.
- said container can be inserted in the pressure container 1 through the neck 2 by means of an operation analogous to screwing, carried out by means of a rotary spindle.
- the propellant is introduced in known manner, for example through a hole in the bottom of the pressure container 1.
- the container 3 when filled with the product the container 3 enables the volume of noxious substances to be reduced to a minimum; moreover, this container does not give rise, during emptying, to residual volumes of inactive substances.
- the principal cross-section of the inner container 3 can be modified from the rectangular section illustrated in Figures 1 and 2 to a rectangular section with sides which are corrugated so as to form concentric ribs on the surface of the helix which enable expansion perpendicular to the axis of the helix.
- the inner container, indicated 6, is in the form of a helical bellows.
- the lateral surface of the inner container therefore behaves like the thread of a screw during the insertion of the container into the pressure container 1 by its being screwed into the hole in the neck of the container 1.
- the helical surface could also be modified in this embodiment so as to enable radial deformation of the bellows.
