There are various brushing methods such as a scrubbing method to remove dirt or a rolling method to move the toothbrush so that it rotates from the gums to the teeth, and the toothbrush used is usually from the tip to the hair plant (head) and neck (neck). , It is composed of three parts of the handle part (handle).

When brushing teeth, generally, a paste-like dentifrice is applied to the flocked portion of the toothbrush in advance, the handle portion is grasped by hand, and the teeth are brushed using the various tooth brushing methods described above.

When brushing teeth as described above, the toothpaste mixed with the toothpaste and saliva accumulates in the oral cavity, and the toothpaste flows down from the flocked part of the toothbrush to the neck part and further to the handle part. At this time, the toothpaste that does not raise the elbow more than the hand holding the toothbrush flows down from the hand to the forearm, and further flows down to clothes such as pajamas worn by the person who is brushing the teeth. Therefore, there is an inconvenience that the clothes are soiled. In addition, since the white streaky stains of the toothpaste adhere to the above-mentioned forearm from which the toothpaste has flowed down, it is necessary to wash the hands and forearms with water or hot water after brushing the teeth. However, it is not uncommon for people to feel the hassle of brushing their teeth due to such inconveniences.

The ridges 5 to be blocked are integrally projected. In the present embodiment, the ridge 5 has a disk shape, but it may have another shape such as a square plate shape.

When brushing teeth with a toothpaste with the toothbrush 1 according to the above-described embodiment, the toothpaste flows from the flocked portion side to the handle portion 4 side due to the presence of the ridges 5 protruding from the neck portion 3. Since this is prevented, the user's hand holding the handle portion 4 does not get dirty with the toothpaste.

As shown in FIGS. 2 to 5, as described above, the toothbrush 1 according to the present invention can be used as a single body in which the ridges 5 are integrally provided on the handle portion 4, but the ridges 5 are used. The toothpaste is prevented (damped) from flowing down from the flocked portion side to the handle portion 4 side, but if the toothpaste receiver 6 described later is used, the toothpaste is collected by the toothbrush receiver 6 and the toothbrush. Since it collects in the neck portion 3 of 1, the convenience of the toothbrush 1 is further improved.

That is, the toothpaste receiver 6 has a substantially bottomed cylindrical shape as a whole, and a circular insertion opening 8 through which the handle portion 4 and the neck portion 3 of the toothbrush 1 are inserted is formed in the bottom portion 6a. An inward flange 9 is formed on the peripheral edge portion of the insertion opening 8, and the upper surface of the inward flange 9 abuts on the lower surface of the ridge 5 to engage the toothpaste receiver 6 with respect to the ridge 5. It has a flexible structure.

More specifically, in the present embodiment, the diameter of the insertion opening 8 of the toothpaste receiver 6 is slightly larger than the outer diameter of the handle portion 4 and the neck portion 3 of the toothbrush 1 and larger than the outer diameter of the ridge 5. By making the size smaller, the handle portion 4 and the neck portion 3 of the toothbrush 1 are inserted into the insertion opening 8 of the toothpaste receiver 6, and the upper surface of the inward flange 9 of the toothpaste receiver 6 is the lower surface of the ridge 5. It has a structure that comes into contact with the toothpaste.

In the present embodiment, as described above, the toothpaste receiver 6 has a substantially bottomed cylindrical shape corresponding to the disk-shaped ridges 5, but the ridges 5 have other forms such as a square plate. If so, the form of the dentifrice receiver 6 is also changed accordingly.

Further, as shown in FIGS. 2 to 5, when the toothpaste receiver 6 is used, the toothbrush 1 is attached to the toothbrush receiver 6 from the base end portion 4a side of the handle portion 4 of the toothbrush 1. The upper surface of the inward flange 9 of the toothpaste receiver 6 is brought into contact with the lower surface of the ridge 5 of the toothbrush 1 by inserting it through the insertion opening 8 of the bottom portion 6a, and in this state, the user uses his / her hand H. The toothbrush 1 is gripped by the handle 4 of the toothbrush 1 with three fingers of the middle finger F3, the medicinal finger F4, and the small finger (not shown), and the toothpaste receiver 6 is picked up and brushed with the thumb F1 and the index finger F2. Toothpaste collects in the liquid reservoir space 11 formed by the ridge 5, the toothpaste receiver 6, and the toothbrush neck 3, and therefore, the toothpaste flows down from the hair-planted portion 2 side of the toothbrush 1 to the handle portion 4. Can be blocked even more sufficiently. After brushing the teeth, the toothpaste receiver 6 is moved from the neck portion 3 of the toothbrush 1 to the base end side of the handle portion 4, the toothpaste receiver 6 is removed from the toothbrush handle portion 4, and the toothpaste is discarded. Hygiene after use of the toothbrush 1 can be easily washed away by simply washing the removed toothpaste receiver 6 and the toothbrush 1 with tap water, respectively. Is easily secured, and the generation of mold like conventional products is surely prevented.

The toothpaste receiver 6 attached to the toothbrush 1 according to the present embodiment has an expanded shape whose outer shape expands from the flange 9 side on the lower end side toward the upper end side, and is more easily received by the toothpaste. It is made into a form. Further, the outer peripheral surface 5a of the ridge 5 of the toothbrush 1 may be tapered in accordance with the form of the toothpaste receiver 6.

However, the configuration of the dentifrice receiver of the present invention is not limited to this, and the outer shape may be the same from the lower end side to the upper end side thereof.

As shown in FIGS. 6, 7 and 8, the toothpaste receiver 6 of the toothbrush 1 may be changed to another structure. For example, the toothpaste receiver 26 has a substantially cylindrical shape as a whole. Further, like the toothpaste receiver 6, the outer shape is expanded from the lower end side to the upper end side, and the upper edge thereof is hooked on the ridge 5 of the toothbrush 1. The bent edge 27 is formed. Further, in the present embodiment, the outer peripheral surface 5a of the ridge 5 of the toothbrush 1 is tapered in correspondence with the form of the spread-shaped toothpaste receiver 26.
