The present invention relates to a hair straightening apparatus having two arms pivotably coupled together and a heating plate on a facing side of at least one arm. A central pack disposed between the first arm and the second arm and coupled to the hair styling apparatus at the hinge end and a biasing means adapted to support the central pack symmetrically between the first arm and the second arm.

A hair styling device (10) comprises first and second arms ((12), (14)), each arm having a handle portion ((18), (20)) coupled to a clamping portion ((22), (24)). The arms are coupled to each other at a first end adjacent the handle portions, allowing the clamping portions to be moveable relative to each other between an open position and a closed position in which a curl forming apparatus may be held between the clamping portions. The clamping portion (22) of the first arm (12) houses a heater element and includes a concave shaped surface heatable by the heater element. The clamping portion (24) of the second arm (14) includes a convex shaped clamping surface. When the clamping portions are in a closed position, the heatable surface of the first arm and the clamping surface of the second arm are spaced apart by a separation distance.

The invention relates to a cosmetic product refill (20) for a hair treatment device (1), comprising an applicator member that is saturated with liquid cosmetic product, with a degree of filling less than or equal to 90%, preferably less than or equal to 80%>, more preferably less than or equal to 70%, the degree of filling being defined as the ratio of the mass of cosmetic product in the applicator member divided by the maximum mass of cosmetic product with which the applicator member can be saturated.

This invention relates to a hair styling device, a hair styling method, and a drive system suitable for use in the hair styling device. The invention relates in particular to a hair styling device (10; 210) for imparting a wave to a section of hair (36) without clamping the section of hair in the wave form. The device has a first forming member (24) and a second forming member (24) with a hair-receiving region (38) between the forming members. A driving member (20; 120) is movable relative to the first forming member and the second forming member to deform the section of hair in the hair-receiving region. The driving member (20; 120) undertakes a two-stage movement as it deforms the section of hair, the driving member in a first stage being movable in a first direction (D1) to drive the section of hair (36) into the hair-receiving region, the driving member (20; 120) in a second stage being movable in a second direction (D2), the second direction being at an angle to the first direction whereby in use to further move the section of hair in the hair-receiving region (38).

A method for hair straightening comprising the steps of heating a hair plate (20) at a working temperature (T), applying to the hair a gas flow that changes the gas environment around the hair, and simultaneously passing the plate (20) slowly over one lock at a time carrying out a plurality of passages. In particular, the gas environment around the hair is composed of air wherein the chemical components have been varied (for example, it is hydrogen enriched), or the oxygen percentage has been varied, or a gas compound normally not present has been added. The relative straightening device comprises a gas flow generator (10) connected, through a conduit (14), to a dispensing plate (20) heated by heating means (21); the generator (10) comprises a hydrogen generator (11) connected to dispensing means (24) provided on the dispensing plate (20) at the heating means (41).

A barrel for a hair styling appliance, the barrel comprising: an external surface; and a heater-mounting surface inside the barrel; wherein the heater-mounting surface is integrally formed with the external surface. For example, the barrel may be formed as a single extruded metal component. Also provided is a barrel assembly comprising such a barrel, and one or more heater elements mounted on the heater-mounting surface. Also provided is a hair styling appliance (e.g. a curling tong, curling wand or hot iron brush) comprising such a barrel assembly. A heater element for a hair styling appliance is also provided, the heater element comprising a substrate having a conductive track for generating heat upon application of an electrical current thereto, and an integral temperature sensor. Manufacturing methods in respect of the above are also provided.

This invention relates to portable heating systems that utilize a portable fuel source. Portable heating systems of the invention generally include a regulator that is configured to vaporize fuel released from a cartridge and to transfer the vaporized fuel to a burner for ignition.
