Abstract

The utility model discloses a toothpick, belonging to the field of toothpick production. The utility model is characterized in that an asepsis plastic foil which is only 0.4 mm thick is used as material, and the rigidity of the asepsis plastic foil is moderate without damaging teeth; the cross section of the toothpick forms a super flat thin shape; one end of the toothpick forms a sharp spine shape or a flat spine shape, and the other end forms a bent hook shape. The flat thin body of the toothpick can be extended in thin tooth gap, the hook-shaped tip of the toothpick can remove animal and plant fibers on the inner sides of the teeth, and the animal and plant fibers on the inner sides of the teeth are not removed by an old toothpick. The utility model which can solve the defects that an old bamboo toothpick and a wood toothpick damage the teeth and has low efficacy can be used for protecting the teeth and raising efficacy of the toothpick.

Description

Toothpick

This utility model relates to a kind of novel toothpick.

Toothpick is the instrument that people are used for rejecting the remaining food of plug in teeth space after meal.For a long time, the toothpick material that people use mainly is two kinds of bamboo and woods, and the shape system of toothpick is amphitypy substantially: the first type transverse section is rounded, and both ends or one end are cone spine shape.The second type transverse section is that prolate is square.One end is point, and an end is sharp and be the dome arc.The shortcoming of these old-fashioned toothpicks is: 1, fragile tooth.Because bamboo and wood is made material, hardness is bigger, has only rigidity, does not have flexibility.This kind of life-time service toothpick, the enamel generation wearing and tearing to dental surface cause the injury to tooth.2, owing to the restriction of material, the cross section diameter of old-fashioned toothpick main body section is all thicker, and only cuspidated a little part can put in teeth space, and thin person is powerless to teeth space.3, the section of old-fashioned toothpick is rounded or prolate is square, does not match with the seam shape of teeth space, adds slightlyer, thereby the effect of picking one's teeth is poor.And pick more and just cause teeth space big more.

Purpose of the present invention is exactly the material and the shape system of the old toothpick of reform, removes the infringement of old-fashioned toothpick to people's tooth, improves the effect of toothpick.

To the effect that of the present invention: one, on material, use the non-toxic plastic thin slice, hard and soft appropriateness, its thickness gets final product for only about 0.4 millimeter.Too thickly then can not stretch very thin teeth space, elasticity is also poor.Too thin then poor rigidity is difficult to reject the food debris in the teeth space.Two, on the shape system of toothpick, because the improvement of material, its transverse section just can become super flat thin type, that is the front said, its thickness gets final product for about 0.4 millimeter.Its widest part is about 5 millimeters, and its length is about 60 millimeters.Whole body is a thin slice.The one end is straight spine shape, or flat spine shape, and the other end is a crotch shape.

The invention has the advantages that: one, can overcome the difficult problem of old-fashioned toothpick to the damage of tooth, what take care of one's teeth is intact.Smooth not coarse because of material therefor, do not have the burr of bamboo wood, unlike bamboo wood, have only rigidity, lack flexible, but coordination of potent and mild therapies, so can not damage tooth, to tooth meat, dental bed is also harmless.Two, effect height.Because of its transverse section is super flat thin type, thus not only most advanced and sophisticated, and also quite a few toothpick body all can put in the teeth space.To removing remaining food in the crack, the effect nature is stronger than old-fashioned bamboo wood toothpicks.Also have a bit, there are two kinds of shapes at novel toothpick tip, and an end is straight spine shape, or flat spine shape, and the other end is a crotch shape.Hooked tip can remove straight tapered tips the food debris that can not remove.Because it is inboard down or than the top, it is out of reach outside in pushing away thorn with the straight pointed end of toothpick that animal and plant fiber is clipped in teeth space sometimes, but as go removing with crotch shape one end, just be easy to.Add this point, the effect of novel toothpick is just higher than the effect of old-fashioned bamboo and wood toothpick.

Claims (1)

1, a kind of novel toothpick, its technology principal character are that the novel toothpick of this kind uses the non-toxic plastic thin slice on material, and its section is super flat thin type on shape system, only about 0.4 millimeter of thickness, the one end is a straight spine shape (2), or flat spine shape (3), and the other end is crotch shape (1).
