In addition, as dental health is lately emphasized again, the toothpick is spotlighted as an essential product in eating to clean teeth and maintain the dental hygiene, so that hundreds of thousands of toothpicks have been consumed.
In addition, in the case of a dental toothbrush made of wire and wool, since the wire may be easily bent or broken only by several uses of the dental toothbrush, the dental toothbrush is uneconomical for the price thereof. Further, dental floss is inconvenient for a user or annoys the user in the use thereof. In addition, the user may put a dirty finger into a mouth in order to use the dental floss, which makes the user feel unhygienic. Accordingly, persons may avoid using the dental floss.
In general, the toothpick has a sharpened portion at one end thereof or both ends thereof. In the state that the sharpened portion of the toothpick is placed between teeth, the toothpick is vertically moved to remove the foreign matters, such as food debris, between teeth.
However, the toothpick according to the related art has a straight-line shape, so that the toothpick may not effectively remove foreign matters inside an oral cavity or between morals.
If the foreign matters inside the oral cavity or at a deep position between the morals are not completely removed, but are neglected for a long time, not only is scale produced, but also bacteria are grown to cause bad breath and damage to gums.
In addition, if the toothpick is forcedly used to remove the foreign matters inside the oral cavity or between morals, the interval between teeth may be gradually widened to cause damage to the gums.
The erroneous use of the toothpick may damage the root of a tooth, thereby causing bleeding or gum disease.
Further, if the typical toothpick according to the related art is used, the foreign matters between teeth may be removed to some extent. However, the toothpick cannot be precisely pushed between the teeth differently from dental floss or an inter-dental brush, and the toothpick may not remove plaque or scale from the teeth.
Therefore, the development of a toothpick capable of simply and effectively cleaning oral cavity is required. Examples of the toothpick are disclosed in Korean Unexamined Patent Publication No. 10-2010-0116024 and Korean Unexamined Utility Model No. 20-2011-0006662.

In general, a toothpick is extensively used for a clean tooth and dental hygiene in our daily lives, and one of manners enabling a user to conveniently and rapidly manage the dental hygiene.
As shown in
However, the straight-type toothpick may not reach an inner part of an oral cavity or a molar so that the management for a clean tooth may be difficult, which may cause decayed teeth or dental disease.
In addition, the toothpick according to the related art may be effectively used only in removing foreign matters from teeth and has a difficulty in removing plaque or scale from the teeth, so that there is a limitation in maintaining clean teeth.
Therefore, the present invention suggests a toothpick capable of simply and efficiently improving dental health.
Hereinafter, a toothpick according to the present invention will be described in detail.
a and 2b are front and plane views showing a toothpick according to one embodiment of the present invention.
Referring to
Hereinafter, the above components will be sequentially described.
The body 10 is provided in the shape of a rod having a long length in a longitudinal direction thereof, and serves as a handle gripped by a user hand. In particular, the body 10 has a thick intermediate portion for the convenient grip so that a user can easily apply force to the toothpick with fingers.
The body 10 is provided at one end thereof with the bending part 10, and provided at an opposite end thereof with the coupling part 40. The unevenness part 30 is coupled with the body 10 through the coupling part 40.
In addition, since the body 10 is gently inclined upward, the toothpick may be slantly inserted into teeth inside an oral cavity to efficiently remove foreign matters between the teeth.
The body 10 may be provided on the surface thereof with a plurality of protrusions 12 including rubber so that the body 10 can be conveniently gripped by fingers without being slipped. Alternatively, the intermediate portion of the body 10 may be flat for the stable grip by the fingers.
The body 10 may include a generally-known plastic material, such as poly propylene or poly ethylene.
Meanwhile, the bending part 20 may be formed integrally with the body 10. The bending part 20 may be sharpened toward an end portion thereof, and may have a triangular section so that the bending part 20 may be inserted between teeth.
The bending part 20 may have a space therein, so that the thickness of the bending part 20 may be changed by external force when the toothpick 5 according to the present invention is used. In other words, if a user puts the bending part 20 of the toothpick 5 between teeth having a narrow interval, the inner space of the bending part 20 is pressed, so that the thickness of the bending part 20 may be changed.
Accordingly, the toothpick 5 can effectively remove foreign matters, such as food debris, even between teeth having the narrow interval without damage to gums.
In the bending part 20 of the toothpick 5, a partial section of the end portion thereof, for example a section, which is about 5 mm distanced from the tip of the end portion thereof, has a solid triangular section allowing the bending part 20 to be easily inserted in the initial stage.
In addition, the bending part 20 may have a bent shape with a curved line. The bending part 20 has a structure appropriate to removing foreign matters between teeth located at a depth position in the oral cavity that the straight type toothpick is difficult to approach.
In other words, the bending part 20 is slantly formed so that the bending part 20 can easily access a space between teeth, such as moral teeth, located in the oral cavity in the state that the user holds the body 10 with a hand, thereby efficiently removing the foreign matters provided at an inner part of the oral cavity or the moral tooth.
The bending part 20 may include an elastic material so that the bending part 20 may be elastically bent to both sides and returned like a spring.
Accordingly, when the bending part 20 may be inserted between teeth irregularly bent, the bending part 20 may be flexibly bent.
In addition, the bending part 20 can prevent the interval between teeth from being widened and prevent teeth and gums from being damaged.
In particular, when a typical toothpick is inserted between the moral teeth, an insertion angle is not desirable, so that the toothpick may be forcedly inserted. Accordingly, the toothpick according to the present invention can solve the above problem.
In addition, a plurality of brushes may be formed on an end portion of the bending part 20, so that the foreign matters, such as food debris, between teeth may be removed due to contact force through the brushing operation.
The brush includes an elastic material to prevent gums or teeth from being damaged, and the length of the brush is gradually shortened toward the end portion of the bending part 20.
Meanwhile, the unevenness part 30 may have a flat shape to solve the problem of widening the interval between teeth as the rod-shape toothpick according to the related art is forcedly pushed between the teeth. In addition, the unevenness part 30 has elasticity so that the unevenness part 30 is not easily broken to protect teeth or gums.
The unevenness part 30 has the size and the thickness sufficient to be inserted between teeth. The unevenness part 30 may remove the foreign matters such as food debris between teeth without damage to gums, and may have a function of massaging the gums.
In addition, the unevenness part 30 may be provided on the surface thereof with a protrusion 32, and the protrusion 32 may include rubber. The protrusion 32 may include a plurality of protrusions, and plaque or scale may be removed from teeth by using the protrusions 32.
In addition, the unevenness part 30 may include an elastic material so that the unevenness part 30 may be elastically bent to both sides and returned like a spring.
Accordingly, when the unevenness part 30 may be inserted between teeth irregularly bent, the unevenness part 30 may be flexibly bent. In addition, the unevenness part 30 can prevent the interval between teeth from being widened and prevent teeth and gums from being damaged.
Meanwhile, the coupling part 40 may couple the body 10 with the unevenness part 30, or may release the coupling between the body 10 and the unevenness part 30 so that the body 10 can be decoupled from the unevenness part 30.
For example, the coupling part 40 is provided at both inner surfaces thereof with female screws, and male screws may be formed at ends of the body 10, the unevenness part 30, and the tooth floss part 50 shown in
The female screw of the coupling part 40 and one of the male screws may be rotated clockwise or counterclockwise for the coupling therebetween. After the coupling therebetween has been finished, the female screw and the one of the male screws are rotated in an opposite direction so that the female screw may be decoupled from the one of the male screws.
According to another example, the coupling part 40 may be provided at both inner surfaces thereof with concave grooves, and convex engaging parts may be formed at one end portions of the body 10, the unevenness part 30, and a dental floss part 50. One of the convex engaging parts is inserted into the groove formed in the coupling part 40, so that the convex engaging part may be coupled with the groove formed in the coupling part 40.
In order to firmly couple the convex engaging part with the groove, the concave groove may have fixing protrusions protruding outward, and the convex engaging parts may have concave protrusions having shapes corresponding to the shapes of the fixing protrusions. When the engaging part is inserted into the concave groove formed in the coupling part 40, since the fixing protrusion is mutually engaged with the convex protrusion, so that the engaging part can be firmly coupled with the concave groove.
In addition, a plurality of protrusions 12 may be formed on the surface of the body 10, so that fingers of the user can conveniently grip the body 10 without being slipped.
Meanwhile, the toothpick 5 according to the present invention may be made through injection molding performed by injecting a synthetic resin source material into a mold. When the toothpick 5 is made of the synthetic resin source material, the toothpick 5 has proper elastic force to prevent pain when the toothpick 5 makes contact with the gums of the user. In addition, the toothpick 5 can be cleaned and reused without being discarded after the toothpick 5 is used once.
In addition, the toothpick 5 according to the present invention is designed suitably for the oral cavity in a simple structure, so that the failure of the toothpick 5 is difficult. Further, the toothpick 5 can be easily used and produced at a low price, and can be used several times.
