Description

Disposable dental floss holder {

The present invention relates to a disposable dental floss having a floss fixed to the dental floss.

In particular, it can be easily cured by improving the grip method of the plate-type dental floss, and the external force is applied to a specific part of the dental floss to adjust the interval between the fixed dental flosses, Disposable dental floss.

Disposable dental floss is a one-time oral cleansing device for easily and cleanly removing foreign substances trapped between teeth.

1 is an example of a conventional disposable flosser.

The conventional disposable dental floss shown in Fig. 1 comprises a plate-shaped grip portion 10, a dental fixation portion 11 formed at one end of the grip portion 10, And a dental floss 12 which is tightly fixed in the form of a (1).

As shown in Fig. 2, the conventional disposable dental floss is constructed by gripping the side face 10a of the grip portion 10 with the thumb and index finger, then pushing the dental floss 12 fixed to the dental fixation portion 11 between the teeth, So that foreign substances sandwiched between the teeth can be removed or cleaned by the dental floss 12 by moving up and down with close contact with the side of the teeth.

However, in the disposable dental floss of the related art, when the side surface 10a of the grip portion 10 is gripped by the thumb and index finger, the grip portion 10 does not coincide with the inserting direction of the floss, So it is difficult to facilitate the flossing.

In addition, when the gap between the teeth is narrow, the dental floss 12 is subjected to a large load in the process of filling the dental floss 12 between the narrow teeth. As a result, there is a problem in that floss insertion can not be smoothly performed due to the stretched dental floss 12, and the end of the dental floss fixing part 11 touches the gum in the process of inserting the dental floss into the teeth, .

Meanwhile, in order to solve the above problems, Japanese Patent Application Laid-Open No. 10-1121950 (prior art) discloses a floss holder capable of adjusting the tension.

The above prior art document is intended to add a winding wheel that can wind a floss mounted on the head of the floss holder, and adjust the tension of the floss by rotating and fixing the winding wheel.

However, since the structure for installing the winding wheel is complicated and the fabrication cost is high, the floss holder of the prior art document is not only unsuitable as a disposable floss member, but also has a problem of contamination of the floss holder due to repeated use.

Hereinafter, embodiments of the present invention will be described.

Fig. 3 is a perspective view of the first embodiment of the disposable dental floss of the present invention, Fig. 4 is a phage view of Fig. 3, and Fig.

3, the disposable dental bench 100 according to the first embodiment of the present invention includes a dental floss body 110, a dental floss 120, a tether 130, and a tension adjusting means 140, .

The floss body 110 is made of a thin plate-like plastic material. Depending on this shape, it can be named as a flat floss.

The dental floss fixing unit 120 is integrally provided at the tip of the dental floss body 110. The first fixing base 121 and the second fixing base 122 are protruded at predetermined intervals to form a substantially U- . A dental floss 123 is fixed at the terminal end between the first and second fixing legs 121 and 122.

It is preferable that the first and second fixing members 121 and 122 have a rigid structure such as a T shape or an H shape in order to prevent the first and second fixing members 121 and 122 from being twisted by a load acting on the floss 123 when dental flossing. However, the present invention is not limited to the above-described embodiment, and it goes without saying that any shape can be applied as long as it is a rigid guiding groove for preventing warping.

Further, it is also preferable that the ends of the first and second fixing bars 121 and 122 are rounded to prevent scratches upon contact with the gums.

The tether 130 is integrally provided at the rear end of the dental floss body 110. The tail portion 130 of the present invention serves as an auxiliary handle and has a shape elongated to the rear of the dental floss body 110.

The tension adjusting means 140 which is a substantial part of the present invention plays a role of pulling the stretched dental floss 123 tightly during the dental flossing process. The dental floss stabilizing unit 120 of the dental floss body 110, 130 formed on the upper surface of the blank portion 141, and a pressing portion provided on the upper surface of the blank portion 141 to be elastically deformed to be depressed into the blank portion 141 or to be elastically restored to its original state And an elastic pressing portion 142.

The elastic pressing portion 142 is a structural portion formed by thinning the thickness of the upper portion of the blank portion according to the configuration of the blank portion 141. Since the elastic pressing portion 142 itself is thin, As shown in FIG. 5, when the elastic pressing portion 142 is pressed by the user's finger, the elastic pressing portion 142 is elastically deformed toward the blank portion 141. When the pressing force is released, As shown in FIG.

In this process, the first fixing table 121 located on the extension line of the one inflection point P of the elastic pressing section 142 is moved in a direction away from the second fixing table 122 with respect to the one inflection point P Is displaced. When the elastic pressing portion 142 is pushed, the first fixing base 121 is deformed outward at an arbitrary inflection point P as a hinge point so that the gap between the first and second fixing bases 121 and 122 The tension of the fixed dental floss 123 between them can be readjusted to a taut state.

As described above, the tension adjustment can be easily implemented by merely changing the structure by removing the existing technology that has been dependent on a separate additional structure, thereby reducing the cost and facilitating the operation.

The tension-adjustable disposable dental chair 100 according to the first embodiment of the present invention is configured such that the elastic pressing portion 142 is symmetrical with the elastic pressing portion 142 with the blank portion 141 therebetween, The grip portion 150 is provided on the surface of the dental floss body 110.

The grip portion 150 is configured to be wider than other portions, so that it is easy to grip the finger. 4, the grip portion on the upper side of the grip portion 150 is, for example, the grip portion of the user's finger and the grip portion 150 on the lower side grips the thumb of the user. However, Of course, can be gripped.

Therefore, unlike the case where the conventional dental floss is gripped by the lateral side and the flap is in an unstable state, the tension-adjustable disposable dental chair 100 according to the first embodiment of the present invention can perform dental flossing A dental floss becomes possible.

It is preferable that a slip prevention structure such as a protrusion (not shown) is provided on the surface of the grip portion 150 if one is added thereto.

Fig. 6 is a perspective view of a second embodiment of the tension-adjustable disposable dental chair of the present invention, and Fig. 7 is a dental tension control state diagram of Fig.

6 and 7, a tension regulating disposable dental chair 100 according to a second embodiment of the present invention includes a dental floss body 110, a dental fixation unit 120, a tether 130, (140) are the same as those in the first embodiment.

However, there is a difference in that the first spring 143 and the second spring 141a are additionally provided in the tension adjusting means 140. [

The first spring 143 further complies with the function of the elastic pressing part 142 of the first embodiment and has a shape curved convexly toward the inside of the dental floss body 110, And the first fixing base 121 and the second fixing base 121 are connected to each other through the inside of the dental floss body 110. Here, the first spring 143 may be made of the same material as the dental floss body 110.

The second spring 141a is formed to protrude from the bottom surface of the blank portion 141 so that the first fixing base 121 is supported by the first spring 143 in the outward direction while elastically supporting the floor portion 143a of the first spring 143 It plays a role of elastic deformation.

6, when the elastic pressing part 142 is pressed, the first spring 143 and the second spring 141a are elastically deformed about the supporting point, and the first fixing base 121 and the second fixing base 141 The distance between the first and second holding members 121 and 122 is increased by displacing the first holding member 122 in the moving direction. As a result, the dental floss 123 between the first and second fixing members 121 and 122 becomes in a tight tension state, thereby enabling easy flossing.

The disposable dental floss of the second embodiment is different from the first embodiment in that a first spring 143 and a second spring 141a are additionally provided for forcibly displacing the first fixing table 143, There is a relative advantage that displacement and restoration of the first fixing table 143 can be implemented more reliably.

Fig. 8 is a perspective view of the third embodiment of the disposable dental floss of the present invention, and Fig. 9 is a use state diagram of Fig.

Referring to FIGS. 8 and 9, the disposable dental floor 200 according to the third embodiment of the present invention can be named as a three-dimensional dental floss having a U-shaped dental implant fixture and a handle disposed at a right angle. The three-dimensional dental floss includes a dental floss 210 and a handle 220.

The dental implant fixture 210 has a U-shape, and the dental floss 211 is fixed on the upper portion thereof in a one-sided shape.

In order to prevent the dental floss 210 from being twisted by a load applied to the dental floss 211 when dental floss is performed, it is preferable that the dental fixation unit 210 has a rigid structure such as a T-shaped or H-shaped cross-sectional shape. However, the present invention is not limited to the above-described embodiment, and it goes without saying that any shape can be applied as long as it is a rigid guiding groove for preventing warping.

The distal end of the handle 220 is integrally connected to the dental fixture 210 and has a U-shaped tunnel shape.

In addition, the wings 221 of the handle 220 have elasticity such that they are widened outwardly or restored inwardly. Therefore, when the wings 221 are widened outwardly by an external force, the denture fixing parts 210 integrally connected to the wings 221 are spaced apart therebetween. Therefore, the tension of the dentures 211 fixed to the denture fixing parts 210 is re- .

On the other hand, at the upper end of the two vanes 221, a pressing portion 221a for pressing the two vanes by the user's fingers to open them is formed. It is preferable that the pressing portion 221a has a larger area than other portions so as not to cause pain when pressing with the fingers, and is curved so that there is no sharp portion.

9, when a finger is placed between the pressing portions 221a formed at the upper ends of the two wings 221 and a force is applied in the downward direction, when the fingers are inserted between the wings 221, The interval between the first and second plates 221 is opened. In this process, since the pressing portion 221a has a streamlined shape and a large area, the wings 221 can be easily opened without finger pain.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification or improvement is possible.
