Description

[Detailed Description of the Invention] The present invention relates to an improvement of a bobbin for a hair curler for wrapping and setting hair.

Conventional hair curler bobbins have either an inner cylinder made of a material with high heat storage properties and an outer cylinder made of hard plastic, or an inner cylinder filled with a heat storage material such as paraffin and an outer cylinder made of hard plastic. These curlers can be used by heating and storing heat using a designated heating device, so quick curling using heat is effective, so compared to conventional curlers that do not have a heating function, they are easier to use when you are busy. It is currently on the market because of its ability to curl hair in a short time, such as in the morning.

However, these are hard, so if you go to bed with your hair wrapped around the bobbin, the bobbin will hit your head and cause pain, and in extreme cases, it can damage your scalp. In addition, it is not possible to curl the hair for a long time while sleeping, and the best way to curl the hair is to wrap it around a heated bobbin and remove it after it cools down, so it is possible to curl the hair for a long time. There are problems such as not being able to do it.

In addition, especially those containing the above-mentioned paraffin have a sealed structure to prevent leakage of paraffin, so there is a risk of explosion in the event of abnormal heating, and there is a drawback that the structure is complicated, such as an explosion-proof structure.

Furthermore, when heating the bobbin, the bobbin is heated from the inner circumferential surface by inserting it into a heating rod, etc., so the inner circumferential surface of the bobbin becomes quite hot, and when winding hair, etc. If you accidentally put your finger inside the bobbin, there was a problem with using it: you would feel quite hot, although you would not get burned.

The present invention was made in view of the above circumstances, and its purpose is to form the bobbin from a heat-resistant elastic material and provide a protrusion on a part or all of the inner circumferential surface of the bobbin. You can sleep with this heated bobbin wrapped around your hair, and there is no limit to how long it can be used.Also, it is safe to use because it does not feel too hot when you touch the inner surface of the bobbin. To provide a hair curler bobbin that exhibits various effects.

A first embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

Reference numeral 1 denotes a substantially cylindrical bobbin integrally formed of a heat-resistant elastic material, such as a synthetic resin such as silicone rubber, and is open at both ends.

Reference numeral 2 denotes a large number of protrusions integrally provided on the outer circumferential surface of the bobbin 1.

Reference numeral 3 denotes a plurality of protrusions as protrusions that are integrally protruded adjacent to each other on the inner peripheral surface of the bobbin 1. Each protrusion 3 is oriented in the axial direction of the bobbin 1, and is located inside one opening side. It is formed continuously along the entire length of the bobbin 1 in the axial direction so as to extend from the circumferential surface to the other opening and the inner circumferential surface.

Reference numeral 4 denotes a heating rod, which has a plurality of heating rods protruding from a heating plate 5 equipped with an electric heater (not shown) (only one rod is shown), whose outer diameter is set by the bobbin 1 defined by the protrusion 3. The inner diameter is set to be the same as or slightly larger than the inner diameter.

Reference numeral 6 denotes a heat insulating plate that can be detached or opened and closed, and is used to prevent heat radiation from the upper opening of the bobbin 1 when the bobbin 1 is heated by the heating rod 4.

When the bobbin 1 is inserted into the heating rod 4 and the electric heater (not shown) of the heating plate 5 is energized, the bobbin 1 is heated by the heating rod 4.

When the bobbin 1 is heated to a predetermined temperature, the bobbin 1 is taken out from the heating rod 4, and hair is wound around it and set.

According to this embodiment, since the bobbin 1 is made of a heat-resistant elastic material, it can be heated and used, and the user can go to bed with hair wrapped around the heated bobbin 1. There is no risk of the bobbin 1 hitting the head and causing pain or injuring the scalp.

Therefore, according to this embodiment, not only can curling be done in a short time when on the go in a busy morning, but also it can be used while sleeping, which was not possible with conventional heated bobbins. The hair can be wrapped around a heated bobbin, cooled, and then removed, which has a synergistic effect with the curling effect caused by heating and the curling effect caused by leaving the hair wrapped for a long time until you wake up. Combined with this, you can get reliable and long-lasting curls.

In addition, since the protrusion 3 is provided protrudingly on the inner peripheral surface of the bobbin 1, even if you accidentally insert your finger into the bobbin 1, as shown by the two-dot chain line in Fig. 1, when winding hair around the bobbin 1, etc. Since the part that comes into contact with the fingers is only the top of the protrusion 3, the area of contact with the fingers is smaller than in a case where the protrusion 3 is not provided, and the user does not feel as hot.

Furthermore, when removing the bobbin 1 from the heating rod 4, in the case of a bobbin without the protrusion 3 as described above, since the bobbin itself is an elastic body, the bobbin is elastically deformed by the gripping force, and almost the entire inner peripheral surface of the bobbin is deformed. Since it comes into contact with the heating rod, a frictional force is generated and it is difficult to pull it out.Therefore, the stronger you grip the bobbin, the greater the surface pressure of the bobbin against the heating rod, making it even more difficult to pull it out.However, according to this embodiment, The portion that contacts the heating rod 4 is only the top of the protrusion 3, and the contact area is small, making it easier to remove.

4 to 6 show second to fourth embodiments of the present invention.

Hereinafter, in FIGS. 4 to 6, the same parts as in FIG. 1 will be denoted by the same reference numerals, and only the different parts will be explained.

First, in the second embodiment shown in FIG. 4, one end opening of the bobbin 1 is closed by an end wall 1a.
It is no longer necessary to provide a heat insulating plate 6 as in the embodiment,
In addition, a stepped portion 4 defines the insertion limit position of the bobbin 1 on the heating rod 4.
There is no need to provide a (see FIG. 2).

Next, in the third embodiment shown in FIG. 5, a plurality of protrusions 7 and 8 are integrally protruded on the inner circumferential surface of the bobbin 1 on one opening side and the other opening side, respectively. The central part is thicker and the inner circumferential surface is smooth with no irregularities.

Even with this configuration, if a finger is accidentally inserted into the bobbin 1, it is unlikely that the finger will go deep enough to reach the central part where the protrusions 7 and 8 are not provided. effect can be obtained.

Further, in the fourth embodiment shown in FIG. 6, a large number of protrusions 9 similar to the protrusions 2 protruding from the outer circumferential surface are integrally provided as protrusions protruding from the inner circumferential surface of the bobbin 1.

Note that the material of the bobbin is not limited to an elastic material such as silicone rubber as in the above embodiment, but even if the material itself is a hard plastic material, a plurality of slits are formed in the longitudinal direction of the bobbin so that the overall structure is elastic. may be caused to occur.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings; for example, the protrusions 3, 7.8 are both oriented in the axial direction of the bobbin 1, but they are oriented in the circumferential direction. It may be directed.

As explained above, the present invention has a structure in which the bobbin is formed into a substantially cylindrical shape from a heat-resistant elastic material, and a protrusion is provided on at least the inner circumferential surface of the bobbin on the opening side. Therefore, the bobbin can be heated and used, and in this case, even if the inner surface of the bobbin is touched with the fingers, it does not feel that hot and is safe for use.

Furthermore, since the bobbin of the present invention is a heat-resistant elastic body, as mentioned above, it is possible to curl hair in a short time by heating and using it, and it is also possible to sleep with hair wrapped around the bobbin, thereby eliminating restrictions on usage time. It can be used day and night without causing damage, and in addition to providing long-lasting curls, the following effects can also be obtained.

(1) Conventional so-called net curlers had a problem with the head becoming cold when going to bed with wet hair after washing in winter, etc., but with the present invention, a heated bobbin is wound around the hair, so this problem can be avoided. It can be resolved.

(2) When winding hair around the bobbin, the elastic deformation of the bobbin allows the hair to fit well around the bobbin, making it easier to wind the hair, and the effect of wrapping is even better.

(3) Compared to a heat storage material filled with paraffin or the like, it is safe because there is no risk of explosion even if it becomes abnormally heated, and the structure is extremely simple as there is no need for an explosion prevention structure.

(4) It can be easily cleaned when it becomes dirty due to long-term use; in this case, since it is an elastic material, it can be easily washed in a washing machine, etc., and because it is heat resistant, it can be disinfected and washed by boiling. It is convenient as a hairdressing and beauty tool because it can always be kept hygienic.
