  In the invention of the present application, in addition to the effects of the invention described above, the stopper member 7 provided on the support portion 2 makes the operation lever 51 non-slidable, so that the conduction path 4 can be fixed in a closed state. Therefore, for example, in the case of a toothbrush, even if the toothpaste is applied with force, the chemical solution L is not unexpectedly ejected from the aerosol can 1 and it is economical that only the necessary amount of the chemical solution L can be used.

  Hereinafter, a toothbrush provided with a dentifrice will be described as an example of an embodiment of the present invention with reference to the drawings. 1 and 2 show a toothbrush according to a first embodiment of the present invention, and FIGS. 3 to 5 show a toothbrush according to the second embodiment.

The toothbrush according to the first embodiment is as shown in FIG. 1 and is used with the aerosol can 1 attached thereto. The aerosol can 1 used in the present embodiment is filled with a dentifrice L having fluidity such as liquid and has an injection port 12a through which the dentifrice L can be ejected outside the can. It is a thing.
The structure of the aerosol can 1 is a well-known structure that has been used for various applications in the past, and is a substantially cylindrical can body 11 filled with a dentifrice L and a hollow projecting from the can body 11. It is cylindrical and includes a stem portion 12 that is capable of injecting the dentifrice L by operating the internal valve mechanism by being pushed into the can body 11. An injection port 12 a is provided at the tip of the stem portion 12.

Here, the structure of the stem portion 12 may be any structure as long as the dentifrice L can be injected by being moved with respect to the can body 11. For example, the stem portion 12 may be swung. It can be implemented in various structures, such as those that are jetted by moving.
Also, as is often seen in aerosol cans used for applications such as insecticides and fragrances, the aerosol can 1 with a tip-like spray button attached to cover the spray port 12a of the stem portion 12 is used. May be.

  The toothbrush according to the present embodiment includes a support portion 2 for supporting the aerosol can 1 and a brush portion 3 having a brush 31 for brushing teeth.

The support portion 2 in the present embodiment has a substantially conical shape, and the base end (bottom surface) side is opened, and a support portion 21 for supporting the aerosol can 1 is provided. In the present embodiment, the support portion 21 is arranged so as to surround the stem portion 12 of the aerosol can 1 so that the claw portion 21 fitted to the end edge portion 13 protrudes from the inner peripheral surface of the support portion 2. The aerosol can 1 and the support portion 2 can be coupled by fitting the end edge portion 13 to the claw portion 21. In the present embodiment, as described above, in a state where the aerosol can 1 and the support portion 2 are combined, the can body 11 of the aerosol can 1 is exposed to the proximal end side of the support portion 2. When brushing teeth using this toothbrush, the user directly holds the can body 11.
In addition, the support part 2 can accommodate the whole or a part of the aerosol can 1 by forming a casing surrounding the aerosol can 1 in addition to the one in which the aerosol can 1 is exposed as in this embodiment. A storage room may be provided.

The brush part 3 is fixed to the tip side of the support part 2. This brush part 3 is provided with a brush 31 for contacting the user's teeth. The brush 31 is planted so as to stand upright on a brush base 32 integrated with the support portion 2. As in the case of a general toothbrush, the brush 31 according to the present embodiment is formed by bundling small-diameter linear bodies made of synthetic resin and arranged in parallel on the brush base 32 at a constant interval. The thickness and length of the linear body constituting the brush 31, the size of the brush 31 itself, and the shape of the brush base 32 are various depending on the tooth part to be brushed heavily and the target age of the user. Can be changed.
In addition, when applying this invention to brushes other than a toothbrush, the brush part 3 shall consist of hard plastics, for example, and the brush 31 was integrally formed with the brush base 32 in the shape of a comb. It is also good.

Between the support part 2 and the brush part 3, the conduction | electrical_connection path 4 which is a hollow channel | path through which the dentifrice L can be let through is provided. The conduction path 4 extends from the distal end side of the pressing member 52 to be described later to the opening 41 provided on the surface of the brush base 32 of the brush portion 3 through the inside of the support portion 2. As a result, the dentifrice L injected from the injection port 12 a of the aerosol can 1 can be guided to the brush portion 3 and supplied to the base of the brush 31.
In this embodiment, the conduction path 4 is provided inside the support part 2 and the brush part 3, but a tube-like conduction path 4 may be separately passed through the support part 2.
Moreover, about the opening part 41, when the brush 31 and the brush stand 32 are integrally formed as mentioned above, it is good also as what was provided in the front-end | tip and side surface of the brush 31. FIG.

  Further, the support portion 2 is provided with an operation mechanism 5 for injecting the dentifrice L from the injection port 12a of the aerosol can 1 by pushing the stem portion 12 of the aerosol can 1 into the can body 11. The operation mechanism 5 includes an operation lever 51 as an operation unit operated by a user, and a pressing member 52 as a transmission unit for transmitting the operation of the operation unit 51 to the aerosol can 1.

The operation lever 51 is supported by the support portion 2 so as to be slidable in the front-rear direction. That is, the sliding direction of the operation lever 51 is parallel to the direction in which the stem portion 12 is pushed into the can body 11 as described above.
The pressing member 52 is interlocked with the slide operation of the operation lever 51, and is a member for pushing the stem portion 12 toward the can body 11 side. In the present embodiment, the pressing member 52 is a cylindrical body extending in the direction in which the stem portion 12 is pushed into the can body 11 as described above, and the dentifrice passage space 52a passes through the inside. The tip portion of the stem portion 12 of the aerosol can 1 is fitted to the inner surface 52b of the pressing member 52, whereby the stem portion 12 and the pressing member 52 are connected.
The operation lever 51 and the pressing member 52 are integrated with each other by fitting.

When the operation lever 51 is slid in the direction of the aerosol can 1 (the right direction in FIG. 1A), the pressing member 52 moves in the same direction. By the moved pressing member 52, the stem portion 12 fitted to the pressing member 52 moves so as to be pushed into the can body 11. Thereby, the valve mechanism provided at the base of the stem portion 12 is operated, and the dentifrice L is injected from the injection port 12a. This dentifrice L passes through the dentifrice passage space 52 a of the pressing member 52 and is guided to the conduction path 4.
When the pressing of the aerosol can 1 by the pressing member 52 is released as described above, the stem portion 12 is removed from the can body 11 by a return biasing means (not shown) provided at the base of the stem portion 12. It naturally returns to the protruding state, and the injection of the dentifrice L from the aerosol can 1 stops.

  In this embodiment, as described above, the operation lever 51 and the pressing member 52 are directly connected by fitting, and the operation lever 51 moves the pressing member 52 directly. It is not limited to this, but may be operated indirectly through gears, links, or the like. Further, the pressing member 52 may be biased by a biasing means such as a spring or rubber so that the operation lever 51 can be moved easily.

  The conducting path 4 is provided with a closing means C for preventing clogging of the conducting path 4 due to the dentifrice L being dried by the outside air. The closing means C opens the conduction path 4 when the dentifrice L is jetted from the aerosol can 1 by the operation mechanism 5. When the above injection is not performed, the closing means C opens the conduction path 4. It will be closed. Since the operation mechanism 5 and the closing means C are interlocked in this way, a separate operation for operating the closing means C is unnecessary and handling is easy.

The closing means C in the present embodiment is a lid member 33 provided in the brush portion 3 and capable of closing the opening portion 41 of the conduction path 4, and has an advantage that it can have a simple structure.
The lid member 33 is supported so as to be slidable with respect to the support portion 2, and is arranged so as to cover the opening 41 provided in the brush pedestal 32 of the brush portion 3. The lid member 33 and the operation lever 51 are integrated by the connecting member 6, and the operation lever 51 and the lid member 33 are connected to each other. Thereby, the operation mechanism 5 and the closing means C are interlocked. That is, when the operation lever 51 is slid in order to inject the dentifrice L from the aerosol can 1, the lid member 33 is opened, and when the operation lever 51 returns to the original state, The opening 41 is blocked.
The lid member 33 and the connecting member 6 are made of a relatively soft material, and easily follow the side surface of the support portion 2 according to the sliding operation of the operation lever 51 as described above. It is supposed to be.

By providing the closing means C by the lid member 33 as described above, the opening 41 provided in the brush base 32 can be closed when the dentifrice L is not sprayed. Thereby, it can prevent that the dentifrice L which exists in the conduction | electrical_connection path 4 touches external air, and is hardened. Therefore, there is no need to frequently clean the fear that the conduction path 4 is clogged, and it is easy to use. Moreover, there is little possibility that the dentifrice L is contaminated by various bacteria present in the outside air.
In this embodiment, the operation mechanism 5 and the closing means C are interlocked. However, a means for operating the closing means C may be provided separately from the operation mechanism 5.

  Further, the support member 2 is provided with a stopper member 7. The stopper member 7 can be fixed in a state where the conduction path 4 is closed by making the operation lever 51 non-slidable. The stopper member 7 in the present embodiment is a chip-like member that can be attached and detached from the support portion 2 at a position on the proximal end side of the operation lever 51. When the stopper member 7 contacts the operation lever 51, the operation lever 51 can be made non-slidable. Thereby, even when the toothpaste is applied with force, the dentifrice L is not unexpectedly ejected from the aerosol can 1, and the necessary amount of the dentifrice L can be used, which is economical.

Here, another embodiment relating to the closing means C will be described. In this embodiment, the brush part 3 itself functions as the closing means C by being provided so as to be movable with respect to the support part 2. Therefore, it is an advantage that a separate member for closing the conduction path 4 such as the lid member 33 in the first embodiment is unnecessary.
In the present embodiment, the brush base 32 of the brush portion 3 is supported so as to be slidable in the front-rear direction with respect to the support portion 2. The brush base 32 is provided with a brush portion side conduction path 4b which is a part of the conduction path 4 so as to penetrate from the back side to the front side. This brush part side conduction path 4b can pass the dentifrice L when it coincides with the support part side conduction path 4a which is also a part of the conduction path 4.

As in the first embodiment, the brush base 32 and the operation lever 51 are integrated by the connecting member 6, and the operation lever 51 and the brush base 32 are connected to each other.
Thereby, the operation mechanism 5 and the closing means C interlock | cooperate. That is, when the operation lever 51 is slid in order to inject the dentifrice L from the aerosol can 1, the brush base 32 becomes conductive when the support part side conduction path 4 a and the brush part side conduction path 4 b coincide. When the operation lever 51 is restored to the original state, the conduction paths 4a and 4b are displaced and are divided so as not to conduct.

  Thus, by providing the closing means C by the brush base 32 slidable with respect to the support part 2, when the dentifrice L is not injected, the conduction path 4 can be closed. Thereby, like Example 1, it can prevent that the dentifrice L which exists in the conduction path 4 touches external air, and is hardened. Therefore, there is no need to frequently clean the fear that the conduction path 4 is clogged, and it is easy to use. Moreover, there is little possibility that the dentifrice L is contaminated by various bacteria present in the outside air.

  The stopper member 7 in this embodiment is slidable in a direction perpendicular to the sliding direction of the operation lever 51. As described above, by providing the sliding stopper member 7 on the support portion 2, the operation lever can be made non-slidable more easily than the chip-like stopper member 7 in the first embodiment. Further, there is no risk of losing the stopper member 7.

In using the toothbrush according to the present invention, the user can brush his / her teeth in the same manner as a general toothbrush by holding the can body 11 of the aerosol can 1. And in order to supply the dentifrice L to the brush 31 of the brush part 3, a user should just slide the operation lever 51. FIG. Thereby, the dentifrice L can be supplied to the brush 31 from the aerosol can 1 through the conduction path 4. In this way, by appropriately operating the operation lever 51, the amount of dentifrice L desired by the user can be guided to the brush 31. Moreover, since the operation lever 51 can be fixed by the stopper member 7, unlike the conventional toothbrush described in Patent Document 1, it is possible to prevent excessive use of the dentifrice L due to the dentifrice L coming out unexpectedly. And economical.
Moreover, since the toothbrush which concerns on this invention is what the dentifrice L was filled in the aerosol can 1, even if the dentifrice L is used up, it is only necessary to replace the aerosol can 1. Therefore, it is very convenient to use.

  Each of the above examples shows an example in which the present invention is applied to a toothbrush. However, a chemical such as a hair brush with a hair lotion, a hair restorer, a hair dye, or a cleaning brush with a cleaning agent is used. It can be applied to various brushes.
