Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an earplug, and more particularly to an earplug with a cover that can be easily removed, has an excellent soundproofing effect, and can be used for a long period of time.
[0002]
[Prior art]
Earplugs that have been used in the past are roughly divided into sponge earplugs and earplugs made of silicon (correctly called “silicone” but commonly called “silicone”). is there.
The earplug 10A made of sponge shown in FIG. 4 is deformed into a thin roll shape, and is inserted into the ear canal. Although the earplug 10A is temporarily reduced by being pressed, the shape gradually recovers after insertion of the ear canal, and the earplug is brought into a state of complete contact with the ear canal, thereby providing a soundproofing effect.
[0003]
In the United States, earplugs made of silicon are widespread. As shown in FIG. 5, the earplug 10B made of silicon is formed into a spherical shape, applied to the ear hole, and pushed and spread around the ear hole with a finger to obtain a soundproofing and waterproofing effect.
[Problems to be solved by the invention]
[0004]
However, in the case of the earplug made of the sponge shown in FIG. 4, the effect of preventing noise is not sufficient due to the material of the sponge, and not only the waste of the ear adheres to the sponge with use, but also the earplug. Since the elasticity of the plug is gradually lost, there is a problem that the function as an earplug is not achieved at an early stage.
In addition, the earplug made of silicon in FIG. 5 is functionally important that the material silicon has adhesiveness to the skin. Due to this adhesiveness, the ear plug is made more prominent than the earplug made of sponge. There is a problem that not only is the material attached and easily soiled, but also the adhesiveness of silicon is lost at an early stage. In addition, if the usage is wrongly inserted into the ear canal, it is difficult to remove, and if it is torn off and remains in the ear canal, there is a problem that the removal becomes even more difficult.
In particular, the earplugs made of silicon are not intended to be inserted into the ear canal, but must be used in the form of sticking to the entrance of the ear hole using adhesiveness. It wasn't possible.
[0005]
In view of the above-described problems, an object of the present invention is to provide an earplug that can be easily removed, has a soundproofing effect, and can be used for a long period of time.
[0006]
[Means for Solving the Problems]
In the present invention, a plug body made of a material having plasticity at room temperature is covered with a cover of a plastic film previously formed into a bag shape,
One end of the cover forms an extraction piece ,
The above problems have been solved by a soundproof earplug that is inserted into the ear canal and attached .
[0007]
[Action]
According to the present invention, since the plug body made of a material having plasticity at room temperature is covered with a plastic film cover, it can be made into a bullet-like pointed shape and inserted deep into the ear canal, thus Higher soundproofing effect can be obtained. Moreover, even if it is inserted deeply into the ear canal, the removal piece is formed at the rear end, so that it can be easily removed.
Further, by covering with a plastic film cover, dirt does not adhere to the plug body, so that it can be used for a long time.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an earplug according to an embodiment of the present invention.
The earplug 10 includes a plug body 20 and a plastic film cover 30 that covers the plug body 20 as a whole.
The plug body 20 has a bullet shape with a sharp tip toward the entrance of the ear hole, and the extraction piece 32 is located at the rear end.
Since the size of the ear canal of each person is different, it is left to the user how long the elongated bullet shape is. Since the plug body is made of a material having plasticity at room temperature, the shape of the ear plug can be freely changed.
The plug body 20 is covered so that the cover 30 forms an extraction piece 32 at the rear end.
By covering in this way, dirt is not directly attached to the plug body 20, so that it can be used for a long time.
Further, since the removal piece 32 is provided, even if the earplug 10 is inserted deep into the ear canal, it is not broken and can be easily removed. Since the earplug 10 has no elasticity, it does not feel like a sponge earplug and can be worn comfortably for a long time.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an earplug according to an embodiment of the present invention.
The earplug 10 includes a plug body 20, to cover the whole plug body 20, a cover 30 of plastic film which is molded in advance bag shape.
The plug body 20 has a bullet shape with a sharp tip toward the entrance of the ear hole, and the extraction piece 32 is located at the rear end.
Since the size of the ear canal of each person is different, it is left to the user how long the elongated bullet shape is. Since the plug body is made of a material having plasticity at room temperature, the shape of the ear plug can be freely changed.
The plug body 20 is covered so that the cover 30 forms an extraction piece 32 at the rear end.
By covering in this way, dirt is not directly attached to the plug body 20, so that it can be used for a long time.
Further, since the removal piece 32 is provided, even if the earplug 10 is inserted deep into the ear canal, it is not broken and can be easily removed. Since the earplug 10 has no elasticity, it does not feel like a sponge earplug and can be worn comfortably for a long time.
[0010]
Next, referring to FIG. 2, a method of wearing the earplug of the present invention will be described.
As shown in the figure, when wearing the earplug of the present invention on the left ear, as with the conventional earplug, turn the right hand behind the head, pinch the right ear, and pull back lightly to attach the earplug. Insert it parallel to the direction of the ear hole. Thus, by inserting the earplug in parallel with the direction of the ear hole, it is possible to insert the earplug deep into the ear canal.
If you feel that the earplugs are too large compared to the size of the ear canal, you can transform it into a thinner shape.
The earplug of the present invention not only makes the ear canal straight by pulling the ear by the above method, but also makes it easy to insert the earplug. Ears are in close contact.
Then, after insertion, the rear end is pressed to be deformed, and the entrance portion of the ear hole can be completely closed.
[0011]
FIG. 3 shows the wearing state of the earplug of the present invention.
FIG. 3A shows the wearing state of the ear plug outside the ear, and FIG. 3B shows the wearing state of the ear plug inside the ear in a sectional view. As shown in these figures, the earplug 10 spreads greatly in the vicinity of the ear hole entrance, and the soundproofing effect can be enhanced by closing the ear hole.
[0012]
【The invention's effect】
According to the present invention, the plug body made of a material having plasticity at room temperature is covered with a plastic film cover as a whole, so that it becomes possible to insert an earplug deep into the ear canal in the form of an elongated bullet, High soundproofing effect can be obtained.
Even if the earplug is inserted deep into the ear canal, it can be easily removed by the take-out piece at the rear end.
Further, by covering the whole with a plastic film cover, there is no waste material from the human body adhering to the plug body, so that it can be used cleanly for a long time.
