Abstract

Hairdryer device, in particular air> flow conveyance mouth (1), to attach to the hot air flow outlet section, comprising a nearly cylindrical body (2) with a circular section inlet (2') and a tapered end (2'), and a portion (3), integral with the body (2) and communicating therewith and having an outlet section (3'). with extended shape with one dimension predominating with respect' to the other, characterised by the presence on its external surface of at least one relief band (4,6,7), such that, in the attachment zone of the relief band, the device is equipped with a lower thermal conductivity, due to the greater thickness and/or attachment of- material which is more insulating than the device material. Said bands permit not directly touching' the hot surface of the mouth (I)'. They achieve the effect of attaining a lower temperature which prevents the possibility of being burnt.

Claims

AMENDED CLAIMS Received by the International Bureau on 17.Jun.2009 (17.06.2009)

1) Hairdryer mouth (1), to attach to the outlet section of the hot air flow from the hairdryer, comprising a nearly cylindrical body (2) with circular section inlet (2') and a tapered end (2"), and a portion (3) integral with the body (2) and in communication therewith and having an outlet section (3') with extended shape with one dimension predominating over the other, wherein on its external surface, of at least one relief band (4, 6, 7), of any shape and size, of the same material as the device or of another suitable material, such that, in the attachment zone of the relief band, the device is equipped with a lower thermal conductivity, due to the greater thickness and/or attachment of material which is more insulating than the device material, characterised by at least one relief band is obtained by attaching a circular ring nut (5) on the circular end of the mouth, equipped with a plurality of reliefs (6) parallel to the axis of the ring nut.

2) Mouth according to one of the claim 1, equipped with a plurality of longitudinal reliefs (4) and a ring nut (5) with a plurality of reliefs (6) parallel to the axis of the ring nut.

3) Mouth according to claim 2, also equipped with spire-shaped reliefs (7) positioned at the tapered portion of the cylindrical body (2).

4) Mouth according to claim 3, where said spires (7) axe five in number. 5) Mouth according to one of the previous claims, where said at least one relief band is co-injected, during the mouth moulding process.

6) Mouth according to one of the previous claims, where said at least one relief band is inserted in the mouth production mould as an insert.

7) Mouth according to one of the previous claims, characterised by the use of soft materials, in particular rubber or silicone.

8) Hairdryer mouth according to one of the previous claims for use for anti-burn function and/or for grip improvement for its handling and/or for anti-scratch purposes.
