IMPROVED HAIR ROLLER
FIELD OF THE INVENTION
The present invention is concerned with an improved hair roller for use in hair styling.
BACKGROUND OF THE INVENTION
There are a variety of styling tools in the market. One type of such tools is a hair roller which can be used to introduce body to hair and/or to change the volume of hair style. Hair rollers are often used with chemicals and other physical treatments during a hair styling process. One problem with such styling process is that it takes a rather long time, often hours before a hair style can be set. The time consumption is contributed by time required for the chemicals to work on the hair, and also time required for heat treatment. The long time required is not practical in many circumstances, for example in the show business which requires a hair style be set in a very short period of time.
Different hair rollers have been proposed which seek to address different hair styling needs. However, there is still desire in the material of a hair roller which can enhance or increase the efficiency of a hair styling process.
The present invention seeks to address these problems, or at least to provide an alternative to the public.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
The present invention is concerned with a hair styling tool and in particular a hair roller for use in, for example, creating style to hair or increase volume of hair configuration.
Fig. 1 and Fig. 2 show are two different side views of an embodiment of a hair roller, designated 2. Fig. 3 shows the hair roller 2 in a disassembled configuration. The hair roller has an inner shell 4, a middle shell 6 and an outer shell 8. The middle shell 6 is slight larger than inner shell 4, and the outer shell 8 is slight larger than the middle shell 6. The shells 4, 6, 8 are dimensioned such that they can be telescopically fitted together. In this embodiment, the middle shell 6 is adhesively connected to the inner shell 4 and the outer shell is 8 connected to the middle shell 6 by way of a tight interference fit. Please see Fig. 4. However, in alternative embodiments, they may be connected together by way of welding.
The inner shell 4 is made of a heat resistant plastic(s) material. While the inner shell 4 generally adopts a cylindrical profile made of a circumferential wall 10 defining a through channel 12 and with openings at opposite ends 14, 16, the inner shell 4 is provided with large cut-out regions 18. As such, the remaining structure of the wall resembles a frame 20 rather than a continuous wall. In this embodiment, the inner shell 4 is made of a material with a specific heat capacity of substantially 1,900 J/Kg-K and a thermal conductivity of substantially 0.16 W/m-K and although studies leading to the present invention have shown that, in the context of the present invention, materials with a specific heat capacity and thermal conductivity of substantially 1800-200 J/Kg-K io and 0.1-0.22 W/m-K, respectively, can equally work.
The middle shell 6 has a similar dimension to that of the inner shell 4 except it is slightly larger. In this embodiment, the middle shell 6 is made of a Velcro-containing structure. This fabric material has the characteristic of providing a surface with small is hooks such that when become contact with hair, it can hold the hair against its surface. In this embodiment, the structure has a base portion covered with a Velcro material. In other embodiment, it is possible that the entire middle structure be made of the Velcro material only. In the context of this description, the reference to “Velcro” encompasses any material has this hook or hair adhesive characteristic. In this embodiment, the specific heat capacity and the thermal conductivity of the middle shell are substantially 1260 J/Kg-K and 3.25 W/m-K, respectively, although studies leading to the present invention have shown that, in the context of the present invention, materials with a specific heat capacity and a thermal conductivity of substantially 850-1670 J/Kg-K and 0.2-6.3 W/m-K, respectively, would equally work.
The outer shell 8 has a similar dimension to that of the middle shell 6 except it is slightly larger. In this embodiment, the outer shell 8 is made of a metallic material with a specific heat capacity and a thermal conductivity of substantially 663 J/Kg-K and 43-205 W/m-K, respectively, although studies leading to the present invention have shown that, in the context of the present invention, materials with a specific heat capacity and a thermal conductivity of substantially 412-913 J/Kg-K and 43-205 W/m-K, respectively, would equally work. The thickness of the outer shell also plays a role. Preferably, as in this embodiment, the outer shell has a thickness of substantially 0.5-0.6 mm.
Fig. 5 illustrates that in an assembled configuration, the hair roller 2 defined a circumferential surface 22. The circumferential surface 22 is defined by a combination of a metallic surface 24 of the outer shell and an exposed Velcro surface 26 from the middle shell 6. This combination surface 24, 26 is resulted from the outer shell 8 provided with a plurality of cut-out regions 30 thus exposing the Velcro surface 26. Please see Fig. 4. In this embodiment, the ratio of the outwardly metallic surface 24 io and the exposed Velctro surface 26 is substantially 60:40, although studies have shown that in other embodiments, it may be substantially 50:50 to 70:30. It is also to be noted that end regions 32, 34 of the outwardly facing surface 22 of the hair roller 2 is defined by the Velcro surface 26.
Fig. 6 illustrate a close-up view of the outwardly surface of the hair roller 2.
Fig. 7 illustrates three different embodiment of hair rollers in accordance with the present invention.
The present invention contains a combination of technical features which contributes to an improved technical function. First, there is provided an outer shell made of a metallic material with specific heat capacity and thermal conductivity characteristics. Conventionally, an outer shell of a hair roller was often subject to high temperature and the outer shell would become very hot. As such, only non-metallic materials were used on the outer shell to reduce the temperature. Yet, in this context of the present invention, the use of a metallic material is counter-intuitive. The provision of the cut-out regions at the outer shell to a specific extent serves to reduce the area of the potentially very hot outer surface and also to expose the Velcro surface such that hair can wrap around the hair roller and be secured thereat. The present invention thus can balance at least factors including the efficiency of treating hair with hair rollers, safety, and securing of the hair rollers to the hair.
Studies leading to the present invention have shown that a hair roller made in accordance with the present invention can more effectively and efficiently treat hair. In particular, due to the provision of an outer metallic shell, not only the thermal conductivity of the hair roller has increase, the heat capacity of the hair roller has also increased when compared with a conventional hair roller with such outer metallic shell. Specifically, experiments have shown that the increase in heat capacity ranges from substantially 60.3% to 73.7% (average 67%). Together also with the increase in thermal conductivity, a hair treatment exercise can be expedited significantly.
