[Industrial application fields]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to an interdental cleaning tool, particularly an interdental cleaning tool having a simple structure, which is formed into an arcuate shape during use and is inserted into the oral cavity and cleans the teeth with a floss corresponding to a bowstring.
[0002]
[Prior art]
Teeth with arch, U-shape, semicircle, etc. made of synthetic resin, with dental floss (hereinafter referred to as “floss”) between both ends and a handle integrally formed at one end of the arch Interim cleaning tools are generally known.
[Problems to be solved by the invention]
However, these interdental cleaning tools have a problem that, while in use, the floss is stretched or the fixation between the floss and the arch stem is loosened, so that the floss is loosened. As a result, it is not only difficult to use, but also difficult to remove food residue and plaque. After all, the purpose as an interdental cleaning tool cannot be achieved.
[0003]
In addition, there are many people who do not care if they always carry the interdental cleaning tool and do not always clean the teeth after meals, but the conventional interdental cleaning tool is too large and bulky, so it is not suitable for carrying.
[0004]
In addition, since the conventional interdental cleaning tool is made of synthetic resin, the mold for manufacturing becomes expensive and the manufacturing cost becomes expensive.
[0005]
The technical problem of the present invention pays attention to such problems, and is a thin plate-like, bulky, small and suitable for carrying, and can be manufactured at low cost, and can be used in a state where tension is applied to the floss, and a simple interdental cleaning tool. Is to realize.
[0006]
[Means for Solving the Problems]
The technical problem of the present invention is solved by the following means. In claim 1, a thin cut plate made of paper, synthetic resin, or the like is provided with a circular or polygonal cut for cutting, and an outer portion of the circular cut is flossed in a diametrical direction, It is designed to be folded in half on the same line as the floss, one end of the floss is connected to the inner side of the annular cut, and when the thin plate is folded in half, In addition, a simple interdental cleaning tool configured to be able to sandwich a circular or polygonal portion separated from the annular cut as a tension plate. The inner part of the annular cut may also be folded in half.
[0007]
In this way, since a cut sheet for annular separation is made in a thin plate made of paper or synthetic resin, it is usually carried in the state of a single thin plate, and when used, if the circular portion is separated from the annular cut line, Since one end of the floss is connected to the inner side of the cut, the circular part can be used as a tension plate. In addition, when the outer part of the annular cut is folded in half on the same line as the floss at the time of use, an arch-shaped recess is formed and the floss is stretched in the diameter direction of the arch-shaped recess. Can be cleaned.
[0008]
And when the thin plate is folded in half, a circular or polygonal portion separated from the annular cut is sandwiched between the two folded portions as a tension plate. If a substantially circular or polygonal part is separated from the cut and sandwiched between two folded parts, the circular or polygonal part can be used as a tension plate. Moreover, since one end of the floss is connected to the tension plate, tension can be applied to the floss by operating the tension plate during interdental cleaning. Therefore, the problem that the floss becomes loose and the interdental cleaning becomes impossible or difficult does not occur.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of how the simple interdental cleaning tool according to the present invention is actualized will be described. FIG. 1 is a perspective view showing a basic configuration of a simple interdental cleaning tool according to the present invention. Reference numeral 1 denotes a main body made of a single thin plate having an arch-shaped recess 2 formed therein. And the floss 3 is stretched between the both ends 2a and 2b.
[0010]
In this figure, the stoppers 3a and 3b are formed in a state in which both ends of the floss 3 pass through the narrow through holes of both ends 2a and 2b of the arch-shaped recess 2 and are pulled out to one side. The retainers 3a and 3b may be formed by making a knot, or may be formed by heating and inflating.
[0011]
The arch stem-shaped portion 1z outside the arch-shaped recess 2 only needs to have a shape that can be easily put into the oral cavity, and the shape is not particularly limited. For easy insertion into the oral cavity, one side of the arch-shaped recess 2 is cut obliquely, like 1a, while the other is cut almost parallel to the cut part 1a, like 1b, A handle portion 1c is formed.
[0012]
Therefore, in the state which inserted this simple interdental cleaning tool in the oral cavity, the handle part 1c can be clamped, the floss 3 can be inserted between teeth, and an interdental can be cleaned. Since the shape is thin, it is not bulky and suitable for carrying. In addition, instead of the straight cut portions 1a and 1b, it may be cut in an arc shape like a chain line.
[0013]
In FIG. 2, one end of a floss 3 is inserted into a semicircular tension plate 4 generated when a portion of the arch-shaped recess 2 is cut out, and a retaining member 3b is formed and connected. Therefore, normally the floss 3 is slack.
[0014]
As a result, if the floss 3 is pulled by operating the tension plate 4 with a finger while the floss 3 is inserted between the teeth, tension can be applied to the floss 3 and the adjacent surfaces of the teeth can be reliably cleaned. .
[0015]
The tension plate 4 can be easily operated so that tension is generated in the floss 3 by overlapping the handle portion 1c with a finger.
[0016]
FIG. 3 shows an embodiment in which the simple interdental cleaning tool of FIG. 2 is realized by folding a thin plate in half. As is apparent from the drawing, the two ends 2a and 2b of the arch-shaped recess 2 are folded in two. As described above, when the double-folded simple interdental cleaning tool is unfolded from the fold and deployed, it becomes a single layer, so that it is easier to carry. In addition, since the single thin plate is used by being folded in two, the strength during use is increased.
[0017]
In other words, when a single thin plate is used as shown in FIG. 1, it is necessary to use a thick and strong thin plate. On the other hand, when it is used as folded in two as shown in FIG. Even thin plates with relatively low strength can be used. In any case, for example, it may be assumed that it is approximately the same as a business card or thicker than a business card.
[0018]
Since the tension plate 4 shown in FIGS. 2 and 3 uses the part cut out when forming the arch-shaped recess 2 as it is, the material can be saved and the manufacture is facilitated. Further, when carrying, the tension plate 4 can be pushed into the arch-shaped recess 2 and stored, so that it is easier to reduce the thickness.
[0019]
FIG. 4 is a plan view of the simple interdental cleaning tool of FIG. 5 is a single thin plate, and the external shape is the shape which developed the simple interdental cleaning tool of FIG. The imaginary line 6 at the center is a crease, and a circular cut 7 is formed at the approximate center. However, the cut line 7 is not necessarily circular, but may be a polygon or the like, and may be any cut line having an annular shape.
[0020]
The floss 3 is passed in advance as shown in the figure. That is, on the left side of the crease 6, starting from the knot 3 a on the lower surface side of the thin plate 5, the tip 2 a side protrudes from the left side of the fold line 6 to the upper side and penetrates from the right side to the lower side of the fold line 6 as indicated by the arrow. Then, it is guided to the hand 2b side as indicated by a broken line, and penetrates upward on the hand 2b side. Further, it penetrates downward on the left side of the crease 6, and then penetrates upward on the inner side of the circular cut 7 and penetrates downward from the right side of the crease 6 to form a knot 3b as shown by a broken line. It is.
[0021]
Therefore, when the both sides 51 and 52 are bent to the upper side of the page with the crease 6 as the center, the state is as shown in FIG.
[0022]
In the embodiment of FIG. 4, the tension plate 4 is folded in a semicircular shape, but in the embodiments of FIGS. 5 to 7, it is a circular tension plate.
[0023]
In FIG. 5, the outer shape of the single thin plate 5 is the same as that of FIG. 4, but the floss 3 has a fold line 6 as indicated by an arrow starting from the knot 3 a on the upper surface side on the tip 2 a side. Penetrate to the lower side, lead to the hand 2b side as shown by the broken line on the lower side, penetrate the upper side on the hand 2b side, and finally penetrate the lower side inside the circular cut 7 that becomes the tension plate 4 , Knot 3b is formed.
[0024]
In the embodiment of FIG. 4, the tension plate 4 is also folded in half at the crease 6 and formed into a semicircular shape. In this embodiment, the inside of the cut 7 is not folded in half, but a circular tension plate. 4
[0025]
Therefore, in use, the circular tension plate 4 is first cut off at the cut line 7 as shown in FIG. Next, the areas 51 and 52 outside the circular cut 7 are bent at the position of the crease 6. That is, when the both sides 51 and 52 are bent to the upper side of the page with the crease 6 as the center, a shape as shown in FIG. 7 is formed, and the arch-shaped recess 2 is formed.
[0026]
The floss 3 is stretched between both ends 2a and 2b on the crease 6 at both ends of the arch-shaped recess 2, and is knotted at substantially the center of the single tension plate 4 sandwiched between the two folded portions. 3b is locked.
[0027]
Therefore, when this simple interdental cleaning tool is inserted into the oral cavity and then operated with the circular tension plate 4 sandwiched between the two folded arch stem portions 51, 52, the tension is applied to the floss 3; Interdental cleaning is possible.
[0028]
The arch-shaped recess 2 and the tension plate 4 do not necessarily have a perfect circle, and may have an elliptical shape or other arc shapes. Moreover, it does not necessarily have to be an arc, and may be a triangle such as a chain line 21, a hexagon such as a chain line 22, or another polygon. Furthermore, it may be an arc, a straight line, or an arch having a continuous corner.
[0029]
FIG. 8 is a plan view corresponding to FIG. 5, and a plurality of configurations similar to those in FIG. 5 are formed with the perforation 8 as a boundary. Therefore, when a single thin plate as shown in this figure is carried, it is separated from the perforation 8 at the time of use, and then a simple interdental cleaning tool for one time is easily assembled by the operation as shown in FIGS. Can be used.
[0030]
FIG. 9 shows an embodiment of the simple interdental cleaning tool of FIG. 5 in which creases 91 and 92 are provided at both ends of the arch stem portions 51 and 52, and folded as shown in FIG. It is a form. Thus, since the handle part 5c becomes four sheets pile, the intensity | strength at the time of use can be made higher.
[0031]
FIG. 11 shows an embodiment in which two flosses are stretched. The bow stem 1z may be single-folded or double-folded, but has a floss 31 on the lower side and a floss 32 on the upper side. Moreover, a floss 32 is stretched on the upper side just above the floss 31 on the lower side, and they are parallel to each other. Eventually, the two flosses 31 and 32 are overlapped in a direction perpendicular to the surface of the arch stem 1z.
[0032]
Therefore, in order to insert the two flosses 31 and 32 between the teeth, the arch stem-like portion 1z is in a horizontal state, the first lower floss 31 is first inserted, and then the upper second floss is inserted. 32 is inserted.
[0033]
For interdental cleaning, the arch stem portion 1z is used in an upright position. Then, one floss 31 cleans one tooth, and the other floss 32 cleans the other adjacent tooth, so that two adjacent teeth can be cleaned at a time.
[0034]
As described above, the configuration in which the two flosses 31 and 32 are stretched so as to be overlapped in the direction perpendicular to the surface of the arch stem-like portion 1z is as easy as the insertion between the teeth as in the case of the single floss. In addition, the two flosses 31 and 32 function independently and efficiently during interdental cleaning, which is extremely effective for busy modern people.
[0035]
The attachment method of the two flosses 31 and 32 to the both ends 2a and 2b of the arch-shaped recess 2 is arbitrary, but in the illustrated embodiment, the knot on the upper side of the proximal end portion 2b of the arch stem portion 1z. 3a as a starting point, after passing through the lower side as indicated by the arrow, the lower floss 31 is formed, and then the upper side is penetrated on the tip 2a side to become the upper floss 32 and return to the hand side. The knot 3b is formed through the lower surface.
[0036]
In this case, if one knot 3a or 3b is extended and connected to a tension plate, the tension plate can be operated independently during use, and the interdental cleaning can be performed in a tensioned state.
[0037]
In addition, the thin plate which forms the simple interdental cleaning tool of this invention is comprised with paper, a synthetic resin, etc. In the case of a synthetic resin thin plate, it may be as thick as a telephone card.
【The invention's effect】
[0038]
As in claim 1, since a cut sheet for cutting the ring is formed in a thin plate made of paper or synthetic resin, it is usually carried in the state of one thin plate, and when used, the circular portion is cut off from the ring cut. Since one end of the floss is connected to the inner side of the annular cut, a circular portion can be used as a tension plate. In addition, when the outer part of the annular cut is folded in half on the same line as the floss at the time of use, an arch-shaped recess is formed and the floss is stretched in the diameter direction of the arch-shaped recess. Can be cleaned.
[0039]
And when the thin plate is folded in half, a circular or polygonal portion separated from the annular cut is sandwiched between the two folded portions as a tension plate. If a substantially circular or polygonal part is cut off from the cut and sandwiched between two folded parts, the circular or polygonal part can be used as a tension plate. Moreover, since one end of the floss is connected to the tension plate, tension can be applied to the floss by operating the tension plate during interdental cleaning. Therefore, the problem that the floss becomes loose and the interdental cleaning becomes impossible or difficult does not occur.
