Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cordless hair curler having a curler section for wrapping and shaping hair.

Conventional technology In conventional cordless hair curlers, when using a cap that is retracted and closed after use on the curler part that wraps and curls the hair, the cap is fitted on the opposite side of the curler part and used as a handle. It was considered.

Generally, this type of cap is made of synthetic resin, and in order to achieve cost benefits, various caps have been considered that do not require separate parts and use the elasticity of the synthetic resin to prevent removal.

For example, as shown in FIG. 4, a convex and concave undercut fitting part 102 is provided on the inner wall of the cap 101, and a concave and convex part corresponding to the fitting part 102 is provided on the curler component 103 and the cap insertion part 104. A portion 106 is provided to prevent removal during fitting.

Further, as shown in FIG. 5, a claw 202 is made to protrude from the open end of the cap 201, and the claw 202 is made elastic so that when it is inserted into the curler part and the cap insertion part, it is fitted into the hook parts 203 and 204, respectively. Aizuki is a stop.

Problems to be Solved by the Invention However, among those with such a structure, in which an undercut is provided on the inner wall of the cap, it is difficult to make the mold for the cap, and the material of the synthetic resin is limited and relatively soft polypropylene is used. .

Only materials such as polyethylene could be used, and as long as the parts were forced to be punched out using a mold, there was a risk that the undercuts would collapse and the dimensional accuracy would be very poor, resulting in variations in the attachment/detachment force and failure to attach/detach accurately.

In addition, for caps with protruding claws, the appearance of the cap is poor, and since the claws protrude from the opening end, if the cap is accidentally dropped, it can sometimes be damaged and the cap loses its function. It was dangerous.

SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a cap that can be smoothly attached and detached without damaging the appearance, and can be reliably prevented from being removed.

Means for Solving the Problem The technical means of the present invention for solving the above-mentioned problem is to provide a hole near the opening end of the cap, provide a slit that is narrower than the diameter of the hole toward the opening, and fill the hole with a hole. A corresponding locking part is provided on the attachment part of the curler part.

For production The technical effect is as follows.

Since the hole provided in the cap is a through hole, it can be processed using a mold structure to avoid undercutting, so the material of the cap is not limited and the dimensional accuracy is high. Also,
The exterior looks good, and there is no risk of breakage if dropped.

In addition, the slit provided in the cap prevents welds from forming when forming the camp, and if it is just a hole, it prevents cracks from occurring due to small force if force is applied to the weld part. It is something that can be done.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In Figures 1 to 3, a check valve 2 for injecting the liquefied combustion gas is provided at one end of a tank 1 that stores liquefied combustion gas, which is the fuel for the cordless hair curler, and a check valve 2 for injecting the liquefied combustion gas is installed at the other end. A curler section 3 for applying and shaping the hair is fixed, and a iron 4 is rotatably held between the curler section 3 and the tank 1, and is always urged toward the curler section 3 to sandwich the hair. It is composed of: 6 is the curler section 3.
This comb includes two rotatable irons 4 and is detachably provided, and is used to create large waves in the hair. Reference numeral 6 denotes a cap provided to encompass the comb 5, which is made of synthetic resin and has a circular locking hole 7 near the open end.
A slit 8 is provided extending from the locking hole 7 toward the open end, and is fitted into a hemispherical locking portion 9 provided on the curler portion 3 to prevent removal. The cap 6 is configured to be inserted into the tank 1 during use, and a hemispherical locking portion 10 and a rib body 11 are provided on the tank 1 at the portions of the cap 6 corresponding to the locking holes 7 and slits 8. They are integrally provided and fit together to prevent them from being removed during use.

Reference numeral 12 denotes a catalyst provided inside the curler section 3, which receives vaporized gas through a nozzle 13 fixed to the opposite side of the check valve 2 of the tank 1 and burns it, and a temperature control section 14 that senses the combustion heat. The ejection of vaporized gas from the nozzle 13 is controlled to perform combustion control, and the temperature of the curler section is controlled to an arbitrary set temperature.

The catalyst 12 is ignited by operating the switch 16, and the nozzle 13 is turned on to eject vaporized gas. Next, by further operating the switch 16, the high voltage generating piezoelectric device 16 is operated, and the generated high voltage is guided to the electrode 17, and a spark is emitted to ignite the vaporized gas. Then, the temperature of the catalyst 12 is raised to the reaction start temperature by the ignition heat, a catalytic reaction is started, the vaporized gas is catalytically combusted, and the combustion continues thereafter.

In the above configuration, when the cap 6 is attached and detached during storage and use, the opening end of the cap 6 is connected to the curler portion 3.
Locking part 9. It tries to cross over the locking part 1° of the tank 1, but at this time, since the slit 8 is provided, the elasticity of the synthetic resin causes the slit 8 part to expand in the outer circumferential direction, and the locking parts 9 and 1 The locking hole 7 and the locking portions 9 and 1° are fitted together, and the cap 6 smoothly passes through the curler portion 3.
The cap 6 is inserted into the tank 1 without being removed, and conversely, the cap 6 is inserted into the curler part 3. It becomes possible to smoothly remove it from the tank 1.

Next, when the curler is used, the rib body 11 fits into the slit 8, so even if rotational force is applied to the cap 6 during use, the rib body 11 acts as a stopper, and the locking part 10 locks the curler. It is possible to prevent the hole 7 from coming off.

Effects of the Invention As described above, the present invention has a circular through hole near the open end of the cap that can be attached to and detached from the tank and the curler part.
By providing a slit from this through hole toward the opening end, and providing a locking portion in the curler portion that fits into the through hole, (1) The presence of the slit suppresses the occurrence of welds during molding. This can prevent cracks from occurring.

(If) Because of the slit, when you get over the locking part during attachment and detachment, the opening end of the camp is elastic and widens in the outer circumferential direction.
can be easily attached and detached.

[Phase] The through holes and slits are provided near the opening end of the cap, so it will not be damaged even if it falls, and the view will be good.

There is no need for forceful punching with a mold, the cap material can be selected according to the purpose, and the dimensional accuracy of the parts is high.

There are other effects.
