Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a dental floss holder for attaching dental floss, which is a filamentous body, for efficiently removing food residues, dental plaque, etc. adhering between the teeth. It is related to.

[Conventional technology]

Conventionally, toothpicks have been widely used as tools for removing food residue, dental plaque, etc. that have adhered between teeth. However, toothpicks often have the problem of damaging the gums and causing diseases such as alveolar pyorrhea.
This cannot be said to be a preferable means for removing food residue and dental plaque.

In addition, when cleaning the teeth with a toothbrush, the bristles of the brush do not fully insert between the teeth, making it impossible to remove food residue and plaque stuck between the teeth, so it is not possible to completely clean the teeth. The problem was that I couldn't do it.

Therefore, in recent years, interdental brushes that are inserted between the teeth to clean between the teeth have come into use, but they are still not suitable for thoroughly cleaning the extremely narrow spaces between teeth and the subgingival margin. There was a problem.

[Problem to be solved by the invention]

Therefore, as a means to eliminate the drawbacks of the above-mentioned conventional technology, a thread-like material that has been sterilized and coated with a chemical solution as necessary is used as a means to easily clean even very narrow spaces between teeth by inserting it between the teeth and moving it. A method of cleaning teeth using dental floss is attracting attention.

If you want to use this dental floss to clean your teeth, you need to insert it into your mouth with the dental floss stretched, and it is a device that can be inserted into your mouth with the dental floss stretched. Various structures of dental floss holders have been proposed.

However, these conventional dental floss holders are composed of many separable parts, and some of these parts may be lost during use, making them unusable or only suitable for one-time use. It is uneconomical because it is a disposable type that only has dental floss that cannot be used, and the structure becomes complicated if it has a built-in long dental floss that can be used many times. Since the guide grooves for pulling out the dental floss are exposed on the outside, foreign matter may adhere to the guide grooves, making it unsanitary, and furthermore, the operation of stretching the dental floss is complicated. There are protrusions on the outer surface for fixing the dental floss, which not only makes it impossible to use it smoothly in the oral cavity, but also has various drawbacks, such as causing damage to the oral cavity when used.

[Means to solve the problem]

In order to eliminate the drawbacks of the conventional dental floss holder, the present inventor has provided a storage section for storing long dental floss so that it can be used many times, and has also provided a storage section for storing long dental floss that can be used many times. Spread between the guide parts provided at the tip of the two-pronged part! 5. C□ram□4.1o Oh wow. , A. Wrap the middle part of the 7.70-piece and hold it once, and then wrap the dental floss on the tip side again, which is passed between the guide parts provided at the tip of the bifurcated part. The storage section and the tensioning section are each composed of two parts that can be opened and closed by a hinge, and when the dental floss is attached, the dental floss is inserted into the fork at the tip. The structure is exposed only between the tips of the separated parts, which improves the appearance and prevents the dental floss in areas other than those used from being contaminated.In addition, each corner has a one-piece structure with a smooth curved surface. This solves the drawbacks of conventional dental floss holders at once, and furthermore, by providing a holding part on the tensioning part side of the storage part to hold the dental floss pulled out from the storage part, the work of tensioning the dental floss is further improved. In addition, a cutting and holding means is provided for cutting and holding the tip of the dental floss that has been stretched between the guide portions provided at the tip of the bifurcated portion of the tensioning portion and then wrapped around the holding portion again. They completed the present invention by discovering that a product with a higher commercial value could be obtained by providing the same.

Each corner has a smooth curved surface so that it can be moved smoothly in the oral cavity without damaging the oral cavity, and it has an integral structure so that there are no parts that can be separated. is important.

In addition, as mentioned above, the storage part 1 is a part that stores the long dental floss F wound around the bobbin B, and when the dental floss F is stretched, the unused part of the dental floss F is stored. Since it is not sanitary for the storage part 1 to be exposed, the hinge parts 1c and 2c, which connect the two parts 1a and lb of the storage part 1 and the two parts 2a and 2b of the tension part 2 so as to be openable and closable, should not be connected to each other. It is preferable that they be provided in the opposite direction so that when opening the tensioning section 2, the storage section 1 will not be opened by mistake.

[Effect]

To use the dental floss holder according to the present invention having the above-described structure, first, the engagement part 1d of the storage part 1 is disengaged, and the two parts 1a and 1b are separated via the hinge part 1c.
The dental floss F is opened to accommodate the dental floss F, and the dental floss F is pulled out to the tensioning part 2 side by a predetermined length, and then the two parts 1a and 1b are closed via the hinge part 1c, and the engaging part 1 is closed.
d engage each other. At this time, if a holding part consisting of a concave part 1f and a convex part 1g is provided on the tensioning part 2 side of the storage part 1, the part of the pulled out dental floss F on the storage part 1 side will be attached to the concave part 1f. This is preferable because it is clamped by the clamping part consisting of the convex part 1g and cannot be pulled out any more easily.

Next, the engagement part 2d of the tensioning part 2 is disengaged, the two parts 2a and 2b are opened via the hinge part 2c, and the storage part 1 is opened.
Wrap the middle part of the dental floss F pulled out from the holding part 2g about once and hold it once, and then wrap the dental floss F on the distal end side at the distal end of the two-forked parts 2e and 2f. After passing between the respective guide parts 2e' and 2f', the wire is wrapped around the holding part 2g twice and held again. It will be easier if a concave portion is provided into which the dental floss F that is stretched around the root is inserted. After such an operation, if one portion 2a is provided with the cutting and holding means 2h, the guide portions 2e' and 2f provided at the tips of the bifurcated portions 2e and 2f, respectively. The cutting/holding means 2h holds the tip of the dental floss F, which has been wrapped around the holding part 2g again and held by the cutting holding means 2h, and is cut. Thus dental floss F
After tensioning, connect the two parts 2a and 2b to the hinge part 2c.
The engaging portions 2d are engaged with each other by closing the engaging portions 2d. At this time, the tips of guide parts 2e' and 2f' provided at the tips of parts 2e and 2f, which are divided into two at the tip of one part 2a of the two parts 2a and 2b, are fitted. When an engaging portion consisting of a fitting portion is provided on the other portion 2b, the tips of the guide portions 2e' and 2f' are fitted into the fitting portion, thereby making the engagement more reliable. When the two parts 2a and 2b of the tensioning part 2 are closed and engaged via the hinge part 2c in this way, the part of the tensioned dental floss F that is exposed to the outside is separated from the two forks at the tip. Since it is only separated between the tips of the parts, the other parts are maintained in a good sanitary condition, and each corner has a smooth curved shape, so when inserted into the oral cavity, It moves smoothly and does not cause any damage to the oral cavity, and since it has an integral structure with no separable parts, it can be used for a long period of time. If the exposed dental floss F becomes contaminated when using the dental floss holder according to the present invention, the two parts 2a and 2b of the extension part 2 are opened via the hinge part 2c and the dental floss F is removed. All you have to do is pull out a predetermined length of dental floss F from the storage part 1, repeat the above operation, and place the new dental floss F so that it is positioned between the two-pronged tip. The dental floss F, which would otherwise be wasted during such operations, can be used only on the contaminated exposed portion, allowing the dental floss F to be used economically.
