Description

The present invention relates to a toothpaste splash preventive device for preventing the scattering of droplets released from the oral cavity when brushing teeth using a toothbrush.

To brush teeth, apply toothpaste to the brush part of the toothbrush, grasp the handle with one hand, put the brush part in the oral cavity, and rub the teeth and gums to brush. While brushing the teeth, droplets of saliva and toothpaste may scatter from the oral cavity, soiling hands and clothes, and causing infections to nearby people.
Various proposals have been made conventionally to prevent the splashing of the droplets. For example, in Patent Document 1, a funnel is detachably fitted to the handle of the toothbrush, and the handle of the toothbrush and the morning glory portion of the funnel are formed. It is disclosed that a liquid receiver is formed between the two.

Further, in Patent Document 2, an oral residual liquid blocking guard is attached to the middle portion of the handle of the toothbrush, and the residual liquid that overflows from the mouth and flows out to the handle during tooth brushing and the scattered residual liquid directly drips downward. It is disclosed to prevent the wetting of clothing.
Further, in Patent Document 3, when brushing teeth in front of a mirror, an insertion portion for detachably penetrating the handle of the toothbrush is provided in a shielding plate that blocks dentifrice and saliva scattered toward the mirror. A toothpaste splash preventer is disclosed.

Japanese Unexamined Patent Publication No. 2003-348 JP-A-2017-209469 Japanese Unexamined Patent Publication No. 2020-11017

However, all of these conventionally proposed ones have little effect of catching droplets scattered from the mouth while brushing teeth, and even if a part of the scattered droplets adheres to the oral residual liquid blocking guard or the shielding plate. , It will flow downward on the surface and drop.
Further, the funnel described in Patent Document 1 and the oral residual liquid blocking guard described in Patent Document 2 are funnel-shaped and therefore difficult to manufacture, and it is also difficult to make the size sufficiently cover the splashing region. The toothpaste splash preventer described in Patent Document 3 has a complicated structure of an insertion portion through which the handle of the toothbrush is detachably penetrated through the shielding plate, which not only requires high manufacturing cost but also takes time and effort for preparation at the time of use, and is easy to use. There was also the problem that it was not good.

This idea was made to solve these problems, efficiently catching the droplets scattered from the oral cavity while brushing teeth to eliminate the dripping flow, and it is extremely easy to put on and take off from the toothbrush and it is easy to use. Moreover, it is an object of the present invention to provide a toothpaste splash preventive tool that can be manufactured at low cost.

The toothpaste splash prevention tool according to the present invention prevents the scattering of droplets generated when brushing teeth, and is composed of a plate-shaped porous elastic body having a size capable of covering a person's mouth. It is characterized in that a small hole is provided in the center of the toothbrush through which the handle of the toothbrush expands and expands.
Instead of the small holes, a predetermined region through which the handle of the toothbrush penetrates may be provided in the center of the plate-shaped porous elastic body, and a plurality of cuts may be formed radially from the center in the predetermined region.
A water-absorbent sheet material having an outer shape equal to or higher than the outer shape of the porous elastic body is provided in these toothpaste splash prevention tools, and a hole through which the handle of the toothbrush is passed is formed in the central portion thereof, and a plurality of locations on the outer peripheral portion are formed. It is preferable to provide a locking portion for hooking on the porous elastic body.

Alternatively, it is made of a plate-shaped porous elastic body having a size that can cover a person's mouth, and a hole through which the handle of the toothbrush is passed is formed in the center, and a space is provided in the circumferential direction between the hole and the outer periphery. Slits may be formed through which the thumb, index finger and middle finger of a person's hand pass.
The toothpaste splash inhibitor according to this invention also consists of a plate-shaped or sheet-shaped flexible water absorber having a size capable of covering a person's mouth, and has a hole or notch formed in the center through which the handle of the toothbrush is passed. A circular hole through which the thumb and index finger of the human hand pass and a long hole through which the middle finger to the little finger pass may be formed between the hole or the notch and the outer periphery.
Alternatively, a band may be provided adjacent to the hole or notch in the center so as not to form the circular hole and the elongated hole, and to pass the index finger or the middle finger of the human hand along one surface of the water absorber.

The toothbrush splash preventive device according to this invention is further composed of a plate-shaped or sheet-shaped foldable water absorber having a size capable of covering a person's mouth, and a pair of notches are formed in a shape symmetrical with respect to the central portion. By bending the portion surrounded by the pair of notches, a hole through which the handle of the toothbrush is passed and a pair of holding pieces for holding the handle of the toothbrush and the water absorber with the fingers of a human hand are formed. It may be the one that is made to be done.
In each of the toothpaste splash prevention tools, it is more preferable that the porous elastic body or the water absorbing body also has breathability.

Since the toothpaste splash prevention tool according to this invention is composed of a plate-shaped porous elastic body or a plate-shaped or sheet-shaped water absorbent body, it is possible to efficiently catch the droplets scattered from the oral cavity during tooth brushing so that the toothpaste splashes downward. There is nothing. In addition, it is very easy and firmly attached to any position on the handle of the toothbrush, so it is easy to use. Moreover, since it has an extremely simple flat structure, it can be manufactured at low cost.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
First, a first embodiment of the toothpaste splash prevention tool according to the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a perspective view of the toothbrush holder, FIG. 2 is a cross-sectional view along the radial direction of the toothbrush splash prevention tool showing a state in which the toothbrush equipped with the toothbrush splash prevention tool is held and used with the right hand, and FIG. 3 is a cross-sectional view. It is a cross-sectional view similar to FIG. 2 which shows an example of another way of holding the toothbrush.

The toothpaste splash prevention tool 1 prevents the scattering of droplets generated when brushing teeth, and is made of a plate-shaped porous elastic body having a size capable of covering a person's mouth, for example, a disk-shaped sponge. .. Then, a small hole 11 is provided in the center of the porous elastic body through which the handle of the toothbrush penetrates while expanding. The opening shape of the small hole 11 may be sufficiently smaller than the cross-sectional shape of the handle of the toothbrush. For example, it is advisable to provide a circular or oval small hole with an inner circumference smaller than the outer circumference of the thinnest portion of the handle of the toothbrush used.

As a specific example, when the width of the thinnest part (the part close to the brush part) of the handle of a standard toothbrush is 5 mm and the thickness is 4 mm, the length of the outer circumference is about 16 to 18 mm depending on the degree of rounding of the corners. .. On the other hand, since the peripheral length of a circle having a diameter of 4.5 mm is 4.5 × π ≈ 14.13 mm, it is sufficient if the small hole 11 is a circular hole having a diameter smaller than this. Further, since it is clear that the circumference of an ellipse having a major axis of 5 mm and a minor axis of 4 mm is shorter than the peripheral length of a rectangle having an inscribed long side of 5 mm and a short side of 4 mm, the small hole 11 is an ellipse having a peripheral length shorter than this. It may be a hole.

If the small hole 11 is too small, the periphery of the hole may be damaged when the handle of the toothbrush is passed through. On the other hand, if the small holes 11 are too large, the elastic restoring force and the frictional force of the porous elastic body cannot be sufficiently obtained, and the toothpaste splash prevention tool 1 cannot be stably and reliably supported by the handle of the toothbrush.
Therefore, a plurality of types of toothpaste splash prevention devices having different sizes of the small holes 11 may be provided so that the user can select the toothbrush according to the thickness of the handle of the toothbrush to be used.

A porous elastic body such as a sponge has a large number of extremely small pores formed on its surface and a large number of extremely small cavities formed therein, and has sufficient water absorption and water retention. The size is arbitrary, but for example, a disk-shaped example having a thickness of 1 cm to 2 cm and a diameter of about 10 cm to 15 cm is shown. The toothpaste splash prevention tool 1 keeps a flat plate shape when no external force is applied, but is elastically deformable with respect to the external force. One of the planes becomes the splash trapping surface 12.

If the handle 21 of the toothbrush 2 to be used is pushed into the small hole 11 of the toothpaste splash prevention tool 1 from the rear end 21a and the small hole 11 is expanded and penetrated, the toothbrush splash is scattered as shown in FIG. The preventive tool 1 can be attached to a desired position in the longitudinal direction of the handle 21 of the toothbrush 2 in a state orthogonal to the longitudinal direction.

When the handle 21 of the toothbrush 2 passes through the small hole 11 of the toothpaste splash prevention tool 1, the porous elastic body around it is crushed in the axial direction and expanded in the radial direction. Therefore, the toothpaste splash prevention tool 1 is stably and surely supported at a desired position of the handle 21 of the toothbrush 2 by the restoring force and the frictional force of the elastic deformation of the porous elastic body.
If a rubber agent is impregnated around the small holes 11 in the porous elastic body constituting the toothpaste splash prevention tool 1, the durability against the insertion and removal of the handle of the toothbrush can be increased.

As shown in FIG. 2, the portion of the handle 21 of the toothbrush 2 to which the toothpaste splash prevention tool 1 is attached, which is exposed on the back surface side of the toothpaste splash prevention tool 1, is formed by the thumb 31 and the index finger 32 of the right hand 3. You can hold it with your middle finger 33 as if you were holding a pencil.
Then, if the brush portion 22 of the toothbrush 2 is put into the oral cavity and the right hand 3 is reciprocated, tooth brushing can be performed. At that time, droplets of saliva and dentifrice are released from the oral cavity to the outside.

Most of the droplets are attached to and captured on the droplet trapping surface (the surface facing the face) 12 of the toothpaste splashing prevention tool 1 arranged so as to cover the front of the mouth. Since the droplet particles are mostly water, they are adsorbed on the droplet trapping surface 12 of the toothpaste droplet scattering prevention tool 1 which is a porous elastic body and are retained inside. Some of the droplets that wrap around to the side or back surface of the toothpaste splash prevention tool 1 are also captured by the outer peripheral surface or back surface of the toothpaste splash prevention tool 1, which is a porous elastic body.

Since this toothpaste splash prevention tool 1 is a porous elastic body such as a sponge, there is no risk of causing pain or injury even if it touches the user's face, so it can be placed very close to the mouth. , It is possible to efficiently capture the droplets emitted from the mouth before diffusing and prevent the diffusion.
After use, the toothpaste splash prevention tool 1 may be washed and stored together with the toothbrush splash prevention tool 1 attached to the toothbrush 2, or the toothpaste splash prevention tool 1 may be removed from the toothbrush 2 and washed and stored.

As shown in FIG. 3, the handle 21 of the toothbrush 2 equipped with the toothpaste splash prevention tool 1 can be held by the right hand 3 with a squeeze grip. In addition, you can brush your teeth by holding the toothbrush in any way you hold it, as in the past.
If the direction of the toothbrush 2 is reversed, the toothbrush 2 equipped with the toothpaste splash prevention device 1 can be similarly brushed with the left hand.

If this toothpaste splash prevention tool 1 is used, the droplets released from the oral cavity during toothpaste can be efficiently captured to eliminate the dripping flow, and the hands and clothes will not be soiled, and the toothpaste can be hygienically brushed. Can be done. Prevents the spread of droplets scattered from the mouth of the sick or care recipient, especially when a nurse, caregiver, or family member assists in brushing the teeth of the sick or care recipient in a hospital, long-term care facility, or home. , It is possible to reduce the risk of infection with new coronaviruses.
In addition, it is extremely easy to attach and detach to the toothbrush and is easy to use, and since it is made of a single material and has a flat plate shape, it can be manufactured at low cost.

FIG. 4 is a cross-sectional view similar to FIG. 3 showing an application example of the toothpaste splash prevention tool of the first embodiment described above. However, the hand holding the handle of the toothbrush is not shown.
In this example, a water-absorbent sheet material 15 having an outer shape equal to or larger than the outer shape of the porous elastic body (in this case, the main body) constituting the splash prevention tool 1 is provided, and the handle 21 of the toothbrush 2 is passed through the central portion thereof. Holes 15a are formed, and locking portions 15b for hooking on the porous elastic body are provided at a plurality of locations on the outer peripheral portion.

The hole 15a may be a circular or oval hole sized to allow the handle of a usable toothbrush to easily pass through.
The water-absorbent sheet material 15 is put on the splash catching surface 12 side of the toothpaste splash prevention tool 1, and the locking portion 15b is hooked on the outer peripheral portion of the porous elastic body (main body) to be locked.
In this state, FIG. 4 shows a state in which the handle 21 is attached to the toothbrush 1 by penetrating the hole 15a of the sheet material 15 and the small hole 11 of the toothpaste splash prevention tool 1.

The sheet material 15 is made of absorbent paper, water-absorbent paper such as Japanese paper or calligraphy, water-absorbent cloth such as gauze or cotton cloth, or non-woven fabric, and at least the locking portion 15b is glued or embedded with wires. Use a piece of paper that has rigidity that allows it to be bent.

If this toothpaste splash prevention tool is used, most of the droplets released from the mouth when brushing teeth are captured on the surface of the sheet material 15. Then, when the water permeates to the back surface side of the sheet material 15, the porous elastic body (main body) absorbs it and holds it.
The sheet material 15 is replaced with a new one each time it is used, but the main body of the porous elastic body can be washed and used continuously. Since the adsorption of droplets to the main body is small, cleaning is easy and the product can be used for a long period of time.

[Second Embodiment]
Next, a second embodiment of the toothpaste splash prevention tool according to the present invention will be described with reference to FIGS. 5 and 6. FIG. 5 is a perspective view of the toothpaste splash prevention tool, and FIG. 6 is a side view showing a state in which a toothbrush equipped with the toothpaste splash prevention tool is held and used with the right hand.

Similar to the first embodiment described above, the toothpaste splash prevention tool 5 shown in FIG. 5 is also made of a plate-shaped porous elastic body having a size capable of covering a human mouth, and has a toothbrush handle in the center. A hole 51 for passing through is formed. The hole 51 may be a circular or oval hole sized for easy insertion of a usable toothbrush handle. Then, one plane becomes the splash supplement surface 52.
Further, slits 53, 54, 55 through which the thumb, index finger, and middle finger of the human hand pass are formed between the hole 51 of the porous elastic body and the outer circumference at intervals in the circumferential direction. The width of the slits 53, 54, 55 may be sufficiently smaller than the thickness of each finger.

When using this toothpaste splash prevention tool 5, the handle 21 of the toothbrush 2 is passed through the hole 51 as shown in FIG. 6, and the thumb 31 and index finger 32 of the right hand 3 are passed from the back surface side of the toothpaste splash prevention tool 5. And the middle finger 33 are inserted into the slits 53, 54, 55, respectively, and penetrated toward the splash catching surface 52 side. At that time, each finger 31, 32, 33 expands each slit 53, 54, 55 and compresses the porous elastic body near the slit, so that the toothpaste splashes due to the restoring force and frictional force of the elastic deformation. The preventive device 5 is securely and stably held by the right hand 3.

Then, the handle 21 of the toothbrush 2 is pressed by the thumb 31, the index finger 32, and the middle finger 33 protruding toward the splash supplement surface 52 of the toothpaste splash prevention tool 5, and the toothbrush 2 and the toothpaste splash prevention tool 5 are positioned together. Can be held. At that time, as shown in FIG. 6, the toothpaste splash prevention tool 5 is curved so that the splash supplement surface 52 is somewhat concave.
The effect of preventing the diffusion of droplets discharged from the mouth when brushing teeth is the same as in the case of the first embodiment, but the curvature of the toothpaste droplet scattering prevention tool 5 increases the droplet catching rate.

If the direction of the toothbrush 2 is reversed, the toothbrush 2 can be held by passing the thumb, index finger, and middle finger through the slits 53, 54, and 55 of the toothpaste splash prevention device 5 in the same manner with the left hand, and the toothbrush can be brushed.

[Third Embodiment]
Next, a third embodiment of the toothpaste splash prevention tool according to the present invention will be described with reference to FIGS. 7 and 8. FIG. 7 is a front view of the toothpaste splash prevention tool, and FIG. 8 is a side view showing a state in which a toothbrush equipped with the toothpaste splash prevention tool is held and used with the right hand.

The toothpaste splash prevention tool 6 shown in FIG. 7 is made of a plate-shaped or sheet-shaped flexible water-absorbing body having a size capable of covering a person's mouth, and a notch 61 through which the handle of a toothbrush is passed is formed in the center thereof. One of the planes becomes the splash supplement surface 62. Circular holes 63 and 64 through which the thumb and index finger of the human hand pass and a long hole 65 through which the middle finger to the little finger pass are formed between the notch 61 in the central portion and the outer circumference.

The flexible water absorbent constituting the splash prevention tool 6 includes water-absorbent and flexible paper such as cardboard, paperboard, and drawing paper, and a water-absorbent cloth or non-woven fabric having shape-retaining properties. A rubber sheet or a resin sheet to which a sponge, cork, or the like is attached can be used.
The notch 61 is formed in a * mark shape so that the handle of the toothbrush can be easily inserted, but the notch 61 is not limited to this and may be formed in a cross shape or a rice-shaped shape. Instead of the notch 61, a circular or oval hole may be formed.

When using this toothpaste splash prevention tool 6, as shown in FIG. 8, the handle 21 of the toothbrush 2 is inserted by pushing and bending the portion of the toothpaste splash prevention tool 6 in which the notch 61 is formed. Then, from the back surface side of the toothpaste splash prevention tool 6, the thumb 31 of the right hand 3 is inserted into the circular hole 63, the index finger 32 is inserted into the circular hole 64, and the middle finger 33 to the little finger are inserted into the elongated hole 65 together.

Then, on the splash supplement surface 62 side of the toothpaste splash prevention tool 6, the handle 21 is pressed by the thumb 31, index finger 32, and middle finger 33, and the toothbrush 2 and the toothpaste splash prevention tool 6 are positioned and held together. At that time, as shown in FIG. 8, the toothpaste splash prevention tool 6 is curved so that the splash supplement surface 62 is somewhat concave.

In this state, tooth brushing can be performed by inserting the brush portion 22 of the toothbrush 2 into the oral cavity and reciprocating the right hand 3. At that time, droplets of saliva and dentifrice are released from the oral cavity to the outside.
Most of the droplets are attached to and captured on the droplet trapping surface (the surface facing the face) 62 of the toothpaste splashing prevention tool 6 arranged so as to cover the front of the mouth. Since the droplet particles are mostly water, they are adsorbed on the water-absorbent droplet trapping surface 12 and held inside, so that they do not drip downward. In addition, the curvature of the toothpaste splash prevention tool 6 increases the splash capture rate.

Since the toothpaste splash prevention device 6 has flexibility, there is no risk of causing pain or injury even if it comes into contact with the user's mouth or face.
If the toothpaste splash prevention tool 6 is made of paper, it may be replaced with a new one after each use. In the case of a rubber sheet or resin sheet with sponge, cork, etc. attached, it can be washed and used many times. Other effects are the same as in the first embodiment.

If the direction of the toothbrush 2 is reversed and the splash supplement surface 62 of the toothpaste splash prevention tool 6 is the surface opposite to the surface shown in FIG. 7, the toothbrush 2 and the toothpaste splash prevention tool 6 can be similarly used with the left hand. You can brush your teeth by holding them together.

[Fourth Embodiment]
Next, a fourth embodiment of the toothpaste splash prevention tool according to the present invention will be described with reference to FIGS. 9 and 10. FIG. 9 is a perspective view seen from the back surface side of the toothpaste splash prevention tool, and FIG. 10 is a cross-sectional view similar to FIG. 3 showing a state in which a toothbrush equipped with the toothpaste splash prevention tool is held and used with the right hand. ..

In the toothpaste splash prevention tool 7 shown in FIG. 9, a hole 71 through which the handle of the toothbrush is passed is formed in the center of a plate-shaped or sheet-shaped water absorbing body 70 having a size capable of covering a person's mouth, and one of them is formed. The flat surface becomes the splash supplement surface. Instead of the hole 71, a notch similar to the notch 61 shown in FIG. 7 may be formed in the center of the water absorbing body 70 so that the handle of the toothbrush can be easily passed through.
Further, adjacent to the hole 71 of the water absorbing body 70, a band 75 through which the index finger or the middle finger of the hand is passed is provided on the back surface (the surface opposite to the splash catching surface).

For the plate-shaped or sheet-shaped water absorbent body 70, the same material as the flexible water absorbent body constituting the splash-scattering preventive tool 6 of the third embodiment described above can be used, but the flexibility is not necessarily obtained. You do not have to have it.
The band 75 may have elasticity like a rubber band, but may have almost no elasticity like a paper band.

When using this toothpaste splash prevention tool 7, the handle 21 of the toothbrush 2 is inserted into the hole 71 from the splash catching surface 72 side of the water absorber 70 as shown in FIG. After that, on the back side of the water absorbing body 70, the index finger 32 of the right hand 3 is inserted into the band 75 along the back side 73, and the handle 21 is grasped with the right hand 3's grip, so that the toothbrush 2 and the toothpaste splash prevention tool 7 are attached. Can be positioned and held together. When the band 75 has elasticity, there is no gap between the finger and the band 75, and the toothpaste splash prevention tool 7 can be held more stably.

The effect of preventing the diffusion of droplets released from the mouth when brushing teeth is substantially the same as in the case of the third embodiment, but since the fingers are not exposed on the splash supplement surface 72 side of the toothpaste splash prevention tool 7, the droplets are sprayed on the fingers. Does not adhere. The middle finger may be inserted into the band 75 instead of the index finger.
If the orientation of the toothbrush 2 and the toothpaste splash prevention tool 7 is reversed from that of FIG. 10 and the toothpaste splash prevention tool 7 is rotated 180 degrees, the toothbrush 2 and the toothpaste splash prevention tool 7 can be similarly put together with the left hand. You can brush your teeth by holding the position.

[Fifth Embodiment]
Next, a sixth embodiment of the toothpaste splash prevention tool according to the present invention will be described with reference to FIGS. 11 to 13. FIG. 11 is a front view of the toothpaste splash prevention tool, and FIG. 12 is a back surface showing a state in which a hole through which the handle of the toothbrush is passed and a pair of holding pieces are formed by bending up the portion surrounded by the pair of notches. It is a perspective view seen from the side. FIG. 13 is a side view showing a state in which the toothbrush equipped with the toothpaste splash prevention device is held and used with the right hand.

The toothpaste splash prevention tool 8 shown in FIG. 11 is composed of a plate-shaped or sheet-shaped foldable water absorbent having a size capable of covering a person's mouth, and one of the plane surfaces thereof is a splash catching surface 82. A pair of notches 85 and 86 are formed intricately as shown in the figure in a shape symmetrical with respect to the central portion.
As shown in FIG. 12, the handle of the toothbrush is passed by bending the portions 87 and 88 surrounded by the pair of notches 85 and 86 at substantially right angles to the back surface 83 side at the portions where the notches are not formed. A hole 81 and a pair of holding pieces 87'and 88'are formed.

Then, as shown in FIG. 13, the handle 21 of the toothbrush 2 is passed through the hole 81 of the toothpaste splash prevention tool 8, and both sides of the handle 21 are sandwiched between a pair of holding pieces 87'and 88', and the handle 21 is sandwiched between the pair of holding pieces 87'and 88'. Hold it between your thumb 31 and index finger 32. Thereby, the water absorber constituting the splash prevention tool 8 together with the handle 21 of the toothbrush 2 can be held at a desired position.
As the plate-shaped or sheet-shaped foldable water absorber constituting the toothpaste splash prevention tool 8, water-absorbing thick paper such as cardboard, paperboard, or drawing paper is suitable.

[Sixth Embodiment]
FIG. 14 is a front view showing a sixth embodiment of the toothpaste splash prevention tool according to the present invention. The toothpaste splash prevention tool 10 of the sixth embodiment is almost the same as the toothpaste splash prevention tool 1 of the first embodiment described with reference to FIGS. 1 to 3.
The difference is that a predetermined region 13 (shown by a broken line in FIG. 14) through which the handle of the toothbrush penetrates is provided in the center of the porous elastic body constituting the toothpaste splash prevention tool 10 instead of the small hole 11. It is only a point where a plurality of notches 14 are formed radially from the center of the predetermined region 13.

When using this toothpaste splash prevention tool 10, the handle of the toothbrush to be used is pushed into the predetermined area 13 from the rear end. As a result, the handle of the toothbrush penetrates the porous elastic body while expanding and expanding the opening by pushing and bending each triangular portion having cuts 14 formed on both sides in the predetermined region 13. As a result, the toothpaste splash prevention tool 10 is stabilized at a desired position on the handle of the toothbrush by the restoring force and frictional force of the elastic deformation of the predetermined region 13 of the porous elastic body constituting the toothpaste splash prevention tool 10. Definitely supported.

In this case, since the amount of elastic deformation of the predetermined region 13 can be made larger than that of the small hole 11 of the first embodiment, the thickness of the handle of the toothbrush that can stably and supportably penetrate the toothpaste splash prevention tool is large. Allowable width increases.
In the example shown in FIG. 14, the notch 14 is formed in a * mark shape so that the handle of the toothbrush can be easily inserted, but the cut 14 is not limited to this and may be formed in a cross shape or a rice-shaped shape. Alternatively, a curved notch may be formed.

Further, the shape of the predetermined region 13 is not limited to a circle, but may be various shapes such as an ellipse, an oval, a polygon including a triangle or a quadrangle, or a deformed shape thereof.
If the predetermined region 13 of the porous elastic body is impregnated with the rubber agent, its durability can be increased.
The water-absorbent sheet material 15 described with reference to FIG. 4 can also be used in combination with the toothpaste splash prevention tool 10 of this embodiment.

[Matters common to each embodiment]
In the toothpaste splash prevention device of each of the above-described embodiments, it is preferable that the porous elastic body or the water absorbing body constituting them also has breathability. The reason is that even if the toothpaste splash preventer moves closer to or away from the mouth when brushing teeth, part of the air during that time flows through the toothpaste splash preventer, so eddy is less likely to occur and splashes. It is possible to reduce the risk of scattering the toothpaste to the side. Also, the air resistance when reciprocating the toothbrush is reduced.

In the case of a porous elastic body, it is sufficient that a large number of holes on the surface and a part of the internal cavity communicate with each other between the front and back surfaces. When the water absorber is made of a non-breathable material such as paper, a large number of small holes penetrating between the front and back surfaces may be formed. The small holes should be sized so that droplets cannot pass through.

The planar shape of the toothpaste splash prevention tool according to this invention is not limited to a circle or a rectangle, and can be any shape. For example, it can be formed into an oval shape, an oval shape, an oval shape, a drum shape as shown in FIG. 15 (a), or the like. Further, it may be a square, a trapezoid, a polygon such as a regular hexagon as shown in FIG. 15 (b), or a modified shape thereof.
