  However, the conventional massage toothbrushes proposed in Patent Documents 1 and 2 and the like have a problem that it is difficult to obtain a sufficient massage effect on gums due to the limitation resulting from the surface shape of the massage part. Moreover, it is desirable to appropriately perform massage on the cheek inner surface, tongue coating cleaning, etc. for maintaining health in the mouth and preventing bad breath, but conventional massage toothbrushes cannot perform them efficiently. Then, this invention makes it a subject to provide the new massage toothbrush which solved the problem in the conventional massage toothbrush, and its manufacturing method.

  The massage toothbrush of the present invention that solves the above-described problems is a massage toothbrush that includes a head having a flocked portion and a grip portion extending therefrom, and has a massage portion formed on a surface of the head other than the flocked portion. And the said massage part is comprised by many loop-shaped fibers (Claim 1), It is characterized by the above-mentioned.

In the massage toothbrush, the massage part can be formed to have a length 1.1 to 2.0 times the axial length of the flocked part (Claim 2).
The said massage toothbrush WHEREIN: The said massage part can be provided in the back part and both sides of a hair transplant part, and the neck part by the hair transplant part side (Claim 3).

Moreover, the manufacturing method of the massage toothbrush of this invention which solves the said subject is equipped with the head which has a hair transplant part, and the holding part extended from it, The manufacturing method of the massage toothbrush which formed the massage part in surfaces other than the hair transplant part in a head It is. And the massage part is formed by adhere | attaching the back surface side of the loop-shaped fiber substrate which fixed many loop-shaped fibers to the board | substrate on the surface to surfaces other than the hair transplant part in the said head (Claim 4). .
In the manufacturing method of the massage toothbrush, the head 2 and the neck 3a where the massage part 5 exists is provided in advance with a step part 3b which is recessed from the other part by at least the thickness of the substrate 7, and the step part is provided with the step part 3b. The loop-like fiber substrate 8 can be bonded (Claim 5).

  Moreover, the manufacturing method of the other massage toothbrush of this invention which solves the said subject is provided with the head part which has a hair transplant part, and the holding part extended from it, The massage toothbrush which formed the massage part in surfaces other than the hair transplant part in a head It is a manufacturing method. Then, a plurality of fixing holes are formed on the surface of the head other than the flocked portion, a plurality of looped fiber bundles in which a plurality of fibers are formed into a loop shape and their fiber ends are bundled are prepared, and the fibers of each looped fiber bundle The massage part is formed by inserting and fixing the end to each fixing hole (claim 6).

  The massage toothbrush of the present invention is characterized in that the massage part is composed of a large number of loop-like fibers. Each loop portion of such a large number of loop-like fibers is a thin linear body, and these linear portions successively rub against the gum surface while making linear contact with each other. It is possible to rub the gums more effectively than rubbing with the uneven surface of the fiber or the tip of the fiber body, and flexibly follow along the complicated gum surface. Therefore, if the massage part of the massage toothbrush of the present invention is rubbed back and forth or left and right so as to press against the gums, it is effective with moderate pressing force and friction force while maintaining sufficient adhesion or followability to the gum surface. Massage can be performed.

  Moreover, since this massage part exists in the back surface etc. of a hair transplant part, naturally it contacts the inner surface of mouth, such as a cheek inner surface, at the time of normal toothbrush operation, and the contact part can be cleaned and massaged simultaneously. And it is possible to perform an effective massage with an appropriate pressing force and frictional force while maintaining sufficient adhesion or followability to the cheek inner surface etc. as in the case of gums. In addition, each loop portion has an advantage that it gently contacts the mucous membrane on the inner surface of the mouth due to its elasticity and deformability. Furthermore, each loop portion can effectively scrape off the cheek inner surface.

  Furthermore, if this massage part is rubbed back and forth, left and right, or circularly as it is pressed against the tongue surface, it will be effective with moderate pressing force and frictional force while maintaining sufficient adhesion or followability to the tongue surface like the gums. The tongue coating can be removed. At this time, the surface of the tongue is not damaged.

  Furthermore, when a toothpaste is attached to the flocked part of the massage toothbrush of the present invention and normal toothbrushing is performed, the massage part composed of a large number of loop-like fibers acts as a whisk for the dentifrice, so the amount of toothpaste used is Less is enough. And while the toothpaste, the massage part can massage and clean the gums and the inner surface of the mouth, so that the blood flow in those parts is improved, the pleasure of massage remains after brushing, and the conventional massage after rinsing the mouth A refreshing feeling that cannot be experienced with a toothbrush is obtained. These various effects can be expected to prevent bad breath, prevent dental caries, prevent periodontal disease, and improve health in the mouth.

  The said massage toothbrush WHEREIN: The said massage part can be formed in 1.1-2.0 times the length of the axial direction of a hair transplant part. According to the results of many use experiments, it was found that when the length of the massage part is within this range, the usability and the massage effect of the massage part on the cheek inner surface can be enhanced. Moreover, the massage part 5 can be formed in any surface other than the hair transplant part 4 in the head 2, for example, as shown in FIG. 1, FIG. 2, five surfaces other than the hair transplant part 4 (a back surface, both side surfaces, a front end surface, a hair transplant part It is desirable to provide the massage part 5 on the side neck part) and to enlarge the massage area as much as possible. However, the massage part 5 can also be formed only on both surfaces or the back surface of the flocked part 4.

The method of manufacturing a massage toothbrush of the present invention is characterized in that a massage part is formed by adhering the back side of a loop-like fiber substrate having a large number of loop-like fibers fixed to the substrate to the surface of the head other than the flocked part. And As the loop-shaped fiber substrate, for example, a loop-shaped fiber substrate used for one side of a hook-and-loop fastener (so-called magic tape (registered trademark)) can be used as it is, so that the massage toothbrush of the present invention can be manufactured inexpensively and efficiently.
At this time, in the case of providing a stepped portion in which the substrate bonding portion is recessed in advance by the thickness of the substrate, the loop-shaped fiber substrate is prevented from being peeled off, and the edge of the substrate does not come into contact with the surface of the oral cavity. Good.

  Another manufacturing method of the massage toothbrush of the present invention is a loop-like fiber in which a plurality of fixing holes are formed on a surface of the head other than the flocked portion, and a plurality of fibers are looped to bundle their fiber ends. A plurality of bundles are prepared, and a fiber portion of each loop-shaped fiber bundle is inserted and fixed in each fixing hole to form a massage part. This method can also efficiently manufacture the massage toothbrush of the present invention.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a main part of the massage toothbrush of the present invention, and FIG. 2 is a plan view. In these drawings, the massage toothbrush 1 includes an elongate head 2 having a flat and substantially square cross section, a neck 3 a extending continuously from the rear end of the head 2, and an elongate grip 3.

  A flocked portion 4 in which synthetic fibers such as polyamide fiber and polypropylene fiber are densely flocked is provided on one flat surface of the head 2. The flocking part 4 is a part for brushing teeth with a dentifrice, and the grip part 3 is a part for gripping by hand when performing brushing or massage. In addition, the length, width, or the rigidity, length, and flocking density of the fibers constituting the flocked portion 4 are appropriately selected depending on the intended user, their preference, purpose of use, and the like.
