ている。2. Description of the Related Art In general, food residues and plaque adhering between teeth that cannot be cleaned well by brushing with a toothbrush alone tend to cause tooth decay, gingivitis and bad breath. It is known to use simple dental floss to remove particles and plaque. A disposable interdental cleaning tool in which a dental floss of a fiber bundle and a holder are integrally formed has been widely used in recent years due to its good simplicity. In particular, conventionally, in order to provide a tooth-tooth cleaning tool having a U-shaped threaded portion in which the dental floss is tensioned at one end of the holder, it is possible to integrate the dental floss by insert molding using a molding die.

を提供することを目的としたものである。In the meantime, in a conventional inter-tooth cleaning tool which is insert-molded with a molding die, a split mold is used, and burrs often occur on the parting surface of the die outside the product. . In the case of an interdental cleaning tool, in the case of an operation in the oral cavity, the burr hits the lips, tongue and gingiva, and often causes discomfort and damages the gingiva. For this reason, adding a deburring process to remove burrs from the product not only lowers productivity and increases production costs, but also degrades the appearance of the product, and requires a cleaning process due to dust generation during deburring. It becomes indispensable and has drawbacks, such as complicated handling and cost reduction is more difficult. The present invention is intended to eliminate these conventional drawbacks. Even if burrs are formed on the product, it is located in the concave portion on the outer curved peripheral surface of the interdental cleaning tool and does not hit the gingiva in the oral cavity. The purpose of the present invention is to provide an interdental cleaning tool in an inexpensive form that can safely clean the teeth without damaging the gums, easily prevent harmful effects, and can greatly improve productivity by eliminating the need for a burr removal step. It is what it was.

Opposite the parting surface of the mold,
A concave portion is formed at a portion including at least the dental floss fixed end outside the bifurcated thread tension portion.

Even when the contact is made in the oral cavity, the burrs are in the recesses, so that the teeth can be safely cleaned without hitting.
In addition, when inserting dental floss into the interdental part of the lower jaw, the thread tension part is held at an angle to the tooth axis and held diagonally, and dental floss can be inserted between the teeth to be easily cleaned and applied to the upper jaw In this case, it is possible to remove plaque from the dental floss fiber bundle without discomfort by the same operation.

FIG. 1 is a perspective view showing an embodiment of the present invention. Which is insert-molded into a tool using a molding die (not shown), which is opposed to a parting surface of the molding die, and which is fixed at least to a dental floss outside the bifurcated thread tension portions 1 and 11. made by forming a recess 10 in the region including the end 1 1, it has a form in which the order of harm can be easily prevented by the recess 10 there is a parting plane.

顎歯間部に斜めに挿入しやすい形となる。In this case, the length of the holder 3 is such that when the grip portion is pinched with the index finger, the middle finger, the finger and the thumb and one of the first tension members 2 is positioned between the teeth, When the second threading portion 22 at the other end reaches near the base of the thumb on the palm side, the first threading portion 2 can be maintained at a predetermined angle oblique to the tooth axis so that the cleaning operation can be performed. Also, the first threading portion 2 and the second threading portion 22 are provided in the holder so as to be opposite to each other with respect to the axial direction of the holder, that is, the threading portion in which the dental flosses 1 and 11 are stretched. The two, 22 may be provided in opposite directions. With this configuration, the holder 3 is pinched and used with the index finger, the middle finger, the finger, and the thumb, but when the dental floss 1 of one fiber bundle is inserted into the interdental region of the lower jaw, the dental floss 11 of the other fiber bundle is Since it faces upward and easily touches the palm, it is naturally held diagonally, and as a result, it is inserted obliquely into the interdental region of the lower jaw. When applied to the upper jaw, the second threaded portion 22 of the holder 3 is directed downward, so that there is no influence on the holding, and as in the case of the conventional product, the second threaded portion 22 is naturally easily inserted obliquely into the intermaxillary teeth.

ことなく他の形態とすることもできる。The dental flosses 1 and 11 are formed integrally with the arched threaded portions 2 and 22 using a fiber bundle of 100 to 1000 denier such as polyamide resin, polyester resin or polyethylene resin. As the thread tension portions 2 and 22, the arms of the fiber bundle fixing front leg portion 6 having the forward inclined portion 4 and the ceiling portion 5 and the fiber bundle fixing rear leg portion 7 are arranged in the holder front end direction and the rear end direction. It is bifurcated at a distance in the front and rear and protrudes almost perpendicular to the dental floss. It is molded at both ends of the holder 3 so that both fiber bundles can be used. Other forms can be adopted without using the part 22.

挿入することによってさらに高められる。As shown in FIG. 1, the first thread tension portion 2 has a forwardly inclined portion 4 in which the fiber bundle fixing front leg portion 6 is inclined forward (in the direction opposite to the holder) in the axial direction of the holder.
And When the dental floss 1 is inserted into the closely-spaced interdental portion by the thread tension portion shape, the thread tension portion 2 is inserted before the dental floss 1 reaches the gingival sulcus after passing through the interdental contact point.
Since the distance between the dental floss 1 and the top part 5 is short, the ceiling part 5 hits the top of the teeth and serves as a stopper. Thereafter, if the thread tension portion 2 is moved to the rear portion of the thread tension portion 2, the distance between the dental floss 1 and the ceiling portion 5 is increased, so that the fiber bundle can reach the gingival sulcus. The thread tension portion 22 can also be used as a similar configuration. In this way, after passing through the interdental contact point, the interdental portion can be safely cleaned without causing the dental floss 1 to directly collide with the gingiva. The function of the forwardly inclined portion 4 of the thread tension portion 2 serving as a stopper immediately after the insertion of the fiber bundle is further enhanced by obliquely inserting the floss.

らである。It is preferable that the first threaded portion 2 and the second threaded portion 22 are mutually convenient and serve as palm contact portions, or that the fiber bundles at both ends of the holder 3 are parallel. This makes it easier to insert the dental floss 1 of the thread tension portion 2 between the teeth diagonally,
In addition, immediately after the insertion, the lower part of the ceiling of the forward inclined portion 4 of the thread tension portion 2 hits the top of the tooth, but it can be learned by feeling. However, if both the fiber bundles 1 and 11 of the holder 3 are not parallel, each This is because it is troublesome to change the insertion angle in the fiber bundle.
