Description

  The present invention relates to a foldable toothbrush, and more particularly, to a foldable toothbrush having a small number of parts and a simple structure, and being hygienic and capable of one-handed operation.

  Conventionally, as a folding toothbrush, for example, techniques described in Patent Documents 1 to 3 are known.

  The foldable toothbrush described in Patent Document 1 is configured such that the brush body 1 and the case 3 can be folded by a pivot 6. The tank 11 in the case 3 is filled with dentifrice, and before opening the brush body 1 in use, the operation piece 15 protruded from the side of the case is moved along the long hole 16, and the pushing device 13 is pushed to press the tank. The dentifrice in 11 is pushed out through the conduction path 12 and the flexible plate 19 is pushed open to attach the dentifrice to the surface of the brush 2. After an appropriate amount of dentifrice is attached to the brush 2 by this operation, the brush body 1 can be rotated and opened to perform brushing as it is (refer to the document [0011] and FIGS. 4 to 6).

  The foldable toothbrush set described in Patent Document 2 is provided with a connecting part on each of the container for storing the toothpaste and the handle of the toothbrush, and provided with a hinge connecting part that can be connected to the seal well, and the hinge connecting part is folded as a rotating sliding structure. The toothpaste is supplied by pushing the push-out part provided in the container through the space for passing the toothpaste provided in the hinge connection part, the supply hole provided in the handle of the toothbrush, and the sealing valve provided in the flocked part. It is configured with a structure that supplies the agent to the toothbrush side.

  The foldable toothbrush described in Patent Document 3 includes a replaceable foldable toothbrush shaft (1), a grip portion (2) that also serves as a case connected by a foldable hinge (6), and a granular dentifrice built in the case. (3) and a fixed-quantity discharge mechanism (4) which rotates in the lower part are provided.

  However, the folding toothbrush described in Patent Document 1 has the following problems.

  The first is that the number of parts is large and the structure is complicated. That is, the operation piece 15, the piston rod 14, the extrusion device 13, and the flexible plate 19 are necessary as parts, and the tank 11 and the conduction path 12 must be formed inside the case 3 as a structure. For this reason, a manufacturing cost becomes high.

  Second, there is a trouble of replenishing the dentifrice. That is, when the dentifrice runs out, it is necessary to open the lid of the injection port 18, insert the tip of the dentifrice tube into the injection port 18, and inject the dentifrice into the tank 11.

  The third is that it is not hygienic. That is, when various germs propagate in the tank 11, the inside of the tank 11 cannot be cleaned or the tank 11 cannot be replaced, which is unsanitary.

  Fourth, both hands must be used to apply the dentifrice to the brush. That is, the case 3 is held with the left hand, the operation piece 15 is operated with the right hand, and the brush body 1 is folded with the right hand, so both hands are required.

  In addition, the folding toothbrush set described in Patent Document 2 has the first to third problems as with the folding toothbrush described in Patent Document 1.

  In addition, the folding toothbrush described in Patent Document 3 has the first to fourth problems as in the case of the folding toothbrush described in Patent Document 1. In addition, granular toothpaste is used because it does not have a structure for squeezing the toothpaste, but the toothpaste must be chewed in the mouth, which is troublesome.

  Therefore, the present invention has been made paying attention to such an unsolved problem of the conventional technology, and has a simple structure with a small number of parts, and is hygienic and capable of one-handed operation. It aims to provide an expression toothbrush.

  [Invention 1] In order to achieve the above object, the folding toothbrush of Invention 1 has a first handle having a brush attached to the brush or a handle having a brush at the tip, and an attachment portion to which a dentifrice tube can be attached. The end of the first handle and the tip of the second handle are connected so as to be foldable, and the tip of the dentifrice tube faces the brush in the folded state. Alternatively, it is arranged near the end of the brush.

  When the first handle has a brush at the tip, first, the dentifrice tube is attached to the second handle. And in the state which folded the 1st handle and the 2nd handle, since the front-end | tip of a dentifrice tube is arrange | positioned in the position which opposes a brush, or near the terminal end of a brush, a 1st handle | stem | pattern is 4 fingers other than a thumb. While supporting, by pressing the dentifrice tube attached to the second handle with the thumb, the dentifrice is discharged from the tip of the dentifrice tube, and the dentifrice is applied to the brush.

  When the first handle has a brush attachment portion at the tip, first, the brush is attached to the first handle, and the dentifrice tube is attached to the second handle. And in the state which folded the 1st handle and the 2nd handle, since the front-end | tip of a dentifrice tube is arrange | positioned in the position which opposes a brush, or near the terminal end of a brush, a 1st handle | stem | pattern is 4 fingers other than a thumb. While supporting, by pressing the dentifrice tube attached to the second handle with the thumb, the dentifrice is discharged from the tip of the dentifrice tube, and the dentifrice is applied to the brush.

  If the dentifrice runs out, the dentifrice tube can be removed from the second handle and a new dentifrice tube can be attached to the second handle.

  Here, the brush of the structure which has an attachment part of a dentifrice tube and a brush is not a structural requirement of the invention 1.

  As described above, according to the foldable toothbrush of the invention 1, since it has only the structure of the first handle and the second handle, the number of parts is small, the structure is simple, and the manufacturing cost can be suppressed. . Further, when the dentifrice is exhausted, it is only necessary to remove the dentifrice tube from the second handle and attach a new dentifrice tube to the second handle, so that the trouble of replenishing the dentifrice can be reduced. Furthermore, when the dentifrice is exhausted, the entire dentifrice tube can be replaced, so it is less likely to become unsanitary compared to the tank structure. Furthermore, if the dentifrice tube is pushed with the thumb while supporting the first handle with four fingers other than the thumb, the dentifrice can be applied to the brush, so that one-handed operation is possible.

It has the terminal side handle 6 which has the part 5 at the terminal, and is comprised.

The attachment portion 2 is configured by forming a thread groove 2 a in the longitudinal direction of the distal end side handle 3 at the distal end portion of the distal end side handle 3. A screw groove that is screwed into the screw groove 2 a is formed on the end side of the brush 1, and the brush 1 can be attached by screwing the end side of the brush 1.

The attachment portion 5 is configured by forming a thread groove 5 a in the longitudinal direction of the end side handle 6 at the end portion of the end side handle 6. On the end side of the dentifrice tube 4, a screw groove is formed to be screwed into the screw groove 5 a, and the dentifrice tube 4 can be attached by screwing the end side of the dentifrice tube 4. A cap 4b is attached to the tip of the dentifrice tube 4 via a hinge 4a.

  The tip side handle 3 is about half as long as a normal toothbrush. The end side handle 6 has a length slightly shorter than half of the front end handle 3. The end side handle 6 is formed with a bearing at the tip end as in the connection structure described in Patent Document 1 (the same reference [0008] and FIGS. 1 and 2), and the end of the end handle 3 is sandwiched between the bearings. It is connected so that it can be rotated 180 ° by a pivot. As shown in FIG. 2, the tip of the dentifrice tube 4 is disposed near the end of the brush 1 in a state where the tip side handle 3 and the end handle 6 are rotated and pivoted about the pivot axis.

  In the state where the distal side handle 3 and the distal side handle 6 are folded, as shown in FIG. 4, the tip of the dentifrice tube 4 is arranged near the end of the brush 1, so the cap 4 b is removed and the distal side handle 3 is removed. The dentifrice is discharged from the tip of the dentifrice tube 4 and applied to the brush by pushing the dentifrice tube 4 attached to the distal handle 6 with the thumb while supporting it with four fingers other than the thumb.

  When brushing teeth, the distal side handle 3 and the distal side handle 6 are developed, and the distal side handle 3 and the distal side handle 6 can be gripped and brushed by the same operation as a normal toothbrush.

  Further, when the dentifrice is exhausted, the dentifrice tube 4 may be removed from the distal handle 6 and a new dentifrice tube 4 may be attached to the distal handle 6.

  Further, when the folding toothbrush 10 is carried, the distal side handle 3 and the distal side handle 6 are folded and accommodated in a case or the like.

Next, the effect of this embodiment will be described.
In the present embodiment, the foldable toothbrush 10 has a distal end handle 3 having an attachment portion 2 to which the brush 1 can be attached at the distal end and an attachment portion 5 to which a part of the distal side of the dentifrice tube 4 can be attached. And the distal end of the toothpaste tube 4 is disposed near the end of the brush 1 in a folded state. The

  Thereby, since it is a structure of only the front end side handle 3 and the end side handle 6, the number of parts is small, the structure is simple, and the manufacturing cost can be suppressed. Further, when the dentifrice is used up, the dentifrice tube 4 can be removed from the distal handle 6 and a new dentifrice tube 4 can be attached to the distal handle 6, thereby reducing the trouble of replenishing the dentifrice. . Furthermore, since the dentifrice tube 4 can be replaced when the dentifrice runs out, it is less likely to become unsanitary compared to the tank structure. Furthermore, if the dentifrice tube 4 is pushed with the thumb while the tip side handle 3 is supported by four fingers other than the thumb, the dentifrice can be applied to the brush 1 and one-handed operation becomes possible.

  In addition, since it is not prevented from using a toothpaste on the structure, when a toothpaste is used, there is no trouble of chewing a toothpaste in a mouth.

  In the present embodiment, the tip side handle 3 corresponds to the first handle of the invention 1, and the end side handle 6 corresponds to the second handle of the invention 1.
