Description

  The present invention relates to an earpick used for removing earwax and the like.

  Conventionally, in order to remove ear wax, an earpick in which a spatula-shaped scraping portion is integrally formed at one longitudinal end portion of a longitudinal rod-shaped gripping portion made of bamboo or synthetic resin, or a longitudinal portion made of wood or synthetic resin A cotton swab in which absorbent cotton is wound around both ends in the longitudinal direction of a rod-shaped gripping part, tweezers, and the like are used.

As a configuration that does not cause pain in the ear, an earpick having a screw shape is proposed in Japanese Utility Model Laid-Open No. 7-33190.
Furthermore, in order to eliminate ear wax and itching at the same time, Japanese Patent Application Laid-Open No. 10-43084 proposes an arrangement of concave and convex shapes of bolts.

  However, the earpicks in Patent Documents 1 and 2 do not clearly specify the pitch of the screws. As inferred from the drawings, the screws in Patent Documents 1 and 2 can be seen as general screws. When the external shape of the screw portion is 3 mm (JIS standard nominal M3), the screw pitch is 0.5 mm, and when the external shape of the screw portion is 4 mm (nominal M4), the screw pitch is 0.7 mm. In other words, the general screw pitch is as small as about 1/6 of the outer diameter of the threaded portion, and the tip of the thread is sharp. It was.

  Further, the earpicks in Patent Documents 1 and 2 are not straight shafts, and a screw portion is disposed only on one end side of the shaft. One earpick is repeatedly used, and the disposable idea is not specified. Therefore, using one earpick by many people is unsanitary and causes infections such as inflammation and illness. Even if it was the same person, if there was some kind of inflammation in one ear, there was a risk that it would pass in the other ear.

  The earpick of the present invention aims to facilitate removal of the earwax without damaging the ear canal. The purpose of this invention is to make it possible to clean both ears with a new earpick with one earpick and prevent inflammation in one ear from infecting the other. Another object of the present invention is to provide an earpick that is inexpensive and disposable.

  The earpick according to the present invention has a plurality of annular grooves arranged at predetermined intervals in the vicinity of both ends of the straight shaft, and the interval (pitch P) between the annular grooves is substantially equal to or greater than the thickness of the straight shaft. As a result, the earwax can be peeled off at the corners of the annular groove and the itchy part can be scratched. Further, by sliding the earpick shaft along the ear canal, the contact area between the earpick and the ear canal increases, and there is very little risk of damaging the ear canal. The arrangement pitch of the annular grooves is made larger than that of the conventional screw, and the acute angle portion of the thread is eliminated. Furthermore, the earwax accumulates in the annular groove by the sliding operation, and the earwax can be easily and efficiently taken out. Even if the scraped-off dust adheres to the ear canal and remains, it can be scraped cleanly in the annular groove. Furthermore, with one earpick, the inside of both ears can be cleaned with a new earpick part.

  Furthermore, the earpick according to the present invention is characterized in that the straight shaft is made of either wood or bamboo, and when the earpick is made of thinned wood, the cost can be reduced and it can be disposable.

  Furthermore, the earpick according to the present invention is characterized in that the diameter of the straight shaft made of wood or bamboo is in the range of 2 mm to 2.5 mm for infants. Cleaning is safe and secure.

  Furthermore, the earpick according to the present invention is characterized in that either a disinfecting solution or a rubber-based paint is provided at an end including at least an annular groove of a straight shaft made of wood or bamboo, and the disinfecting solution is a bacteria. Prevent infection and inflammation. Rubber paint can soft touch the ear canal, reduces the risk of damaging the ear canal, and promotes peeling and adhesion of ear wax.

  With the above configuration, the earpick of the present invention can easily and safely remove the earwax in a short time without damaging the ear canal. With one earpick, the inside of both ears can be cleaned with a new earpick part, and infection such as inflammation can be prevented. Furthermore, an earpick that is inexpensive and disposable can be provided. The disinfectant prevents bacterial infection and inflammation. The rubber-based paint reduces the risk of damaging the ear canal and promotes peeling and adhesion of the earwax.

  The earpick according to the present invention is as described above. The member constituting the earpick may be any member that is generally used. For example, injection with antibacterial wood such as copper, stainless steel, brass, aluminum, titanium, or antibacterial wood such as bamboo, hinoki, oak, general thinned wood, or resin such as polyethylene resin or polystyrene What is necessary is just to shape | mold.

  When the earpick of the present invention is made of general thinned wood other than antibacterial wood, it is preferable to disinfect it in advance for use. What is necessary is just to boil hot water, or to immerse in a disinfectant, apply a disinfectant, impregnate the disinfectant, etc. The disinfectant is, for example, one selected from ethanol, cresol soap, cresol, hydrogen peroxide, chlorhexidine, popidone iodine, chlorhexidine gluconate, peracetic acid 6% disinfectant, 2% glutaraldehyde, photocatalyst, etc. That's fine. The range provided with the disinfectant may be the entire straight shaft, or preferably provided at both ends including at least the annular groove.

  Furthermore, it is good also as a structure which apply | coats the rubber-type coating material in the thickness of 10 micrometers-30 micrometers to the both-ends part including the annular groove | channel of a straight axis | shaft. The rubber-based paint reduces the risk of damaging the ear canal and promotes peeling of the ear wax by increasing the frictional force with the ear canal. In addition, adhesion of earwax to the surface of the rubber-based paint increases. The rubber-based paint may be any member such as butyl rubber, silicon rubber, or soft vinyl chloride.

  The shaft member constituting the earpick of the present invention is preferably a straight shaft. The cross-sectional shape of the shaft is preferably either circular or square. In the case of a circle, the diameter is preferably in the range of 2 mm to 4 mm, preferably in the range of 2.2 mm to 3 mm. In the case of infants, it is preferable to make it slightly thin, about 2 mm. By narrowing the diameter of the straight shaft, it becomes easier to see inside the ear canal, and infants can clean the ear wax safely and securely. The length of the straight shaft is preferably in the range of 50 mm to 70 mm, preferably about 60 mm. It is preferable that the end surface of the straight shaft is C, R, or spherical so as not to damage the inside of the ear.

  The width of the annular groove is preferably about 1.0 mm to 1.2 mm and the depth is about 0.3 mm to 0.4 mm. Although it is sufficient that two annular grooves are provided in the vicinity of both ends, it is obvious that two or more annular grooves may be provided with an arrangement interval (pitch P) of about 3 mm to 5 mm. The arrangement pitch P of the annular grooves is substantially equal to or greater than the thickness of the straight shaft, for example, about 2 mm to 4 mm, preferably about 2.5 mm to 3.5 mm.

  The earpick of the present invention will be described below with reference to the drawings. FIG. 1 shows a front view of an earpick according to an embodiment of the present invention.

  The earpick 100 shown in FIG. 1 is composed of a straight shaft 10 made of antibacterial wood cocoons. The length L of the straight shaft 10 was 60 mm, and the diameter φD was 2.5 mm. Three annular grooves 20 each having a width of 1.2 mm (symbol W) and a depth of 0.3 mm (symbol X) were disposed at predetermined intervals at positions 2 mm from the both end faces (symbol L1). The arrangement interval (pitch P) of the annular grooves 20 was about 3 mm. The C mentory on both end faces was about 0.5 mm. The bottom diameter φD2 of the annular groove 20 is 1.9 mm.

  With the above configuration, the earpick according to the present invention allows the annular groove 20 to peel off the earwax and scratch an itchy part. Further, by sliding the earpick, the contact area between the earpick and the external auditory canal is increased, and the earwax can be easily and efficiently taken out without damaging the external auditory canal. Using both sides of one earpick, the inside of both ears can be cleaned with a new earpick part. In addition, it is made of wood and can be used at low cost.

  FIG. 2 shows a connected earpick 200 in which the earpick 150 obtained by processing thinned wood into the shape and dimensions shown in FIG. 1 of the embodiment is sterilized with an ethanol solution and then wrapped with a paper member. The earpick 150 housed in a paper packaging bag can be cut and used one by one by the perforation 50, and is configured to be hygienic and disposable. It is obvious that a resin film may be laminated on the inner surface of the packaging bag or a moisture-proof resin may be applied.

  The earpick of the present invention is useful not only for humans but also for various pets such as dogs and various domestic animals.
