Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a toothpaste set consisting of an assembly of a toothbrush and a toothpaste storage tube.

<Conventional technology and its problems to be solved> Recently, toothpaste storage containers that automatically suck out toothpaste through a plunger pump action by push button operation have been commercially available, but they are only suitable for toothbrushes. Since toothpaste must be applied to the bristles using a known conventional method, this is still inconvenient for carrying when traveling or for brushing teeth.

<Means for solving the problem> The present invention is intended to improve such problems, and for this purpose, as a tooth brushing set, brush bristles are implanted at the front end of the stay that protrudes forward from the hollow grip tube. By attaching a cap tube from the front to the housing tube body filled with the toothbrush and toothpaste, the cylinder is restrained and fixed inside the housing tube body, and the cylinder is inserted from the front of the housing tube body toward the toothpaste drop hole of the cap tube. The toothpaste storage tube, which once had a communicating flow path, and the plunger enter the cylinder of the cap tube.
The pump is provided with a pump frame which is inserted so as to be inserted and installed so as to be slid along the front and back direction, and which is normally in a pressure state to close the drop hole, and sucks out toothpaste from the storage tube body and drops it by the pumping action of the plunger, and the pump Insert the storage tube with the attached frame into the grip tube of the toothbrush so that it can only be slid in the front-back direction, and when you slide it forward toward the bristles of the toothbrush, the drop hole of the cap tube will open. At the same time, the toothpaste is sucked out by itself with the plunger,
It is characterized by being designed so that it can be applied to brush bristles.

<Example> Hereinafter, the specific structure of the present invention will be described in detail based on the illustrated example.
is a general term for toothbrushes made from colored synthetic resin material, and is equipped with a hollow grip tube 11 of a certain length. 12 is a stay that continuously extends forward from the grip tube 11 by a certain length L1,
Needless to say, brush bristles 13 are implanted and integrated into the front end.

It is a slide operation piece that integrally projects from the rear end of the storage tube main body 19, and is a slide operation piece that extends from the rear end of the storage tube main body 19,
When assembled with the grip tube 11, it engages with the slide guide groove 17 thereof.

Reference numeral 24 designates a cap tube which is removably screwed onto the housing tube main body 19 from the front and is also made of a colored synthetic resin material. 25 is an intermediate partition wall of the cap tube 24, and the front half of this is used as a spring storage chamber S1.
The same rear parts are respectively defined as cylinder storage chambers S2. 26 is a cylinder restrained and fixed within the cylinder storage chamber S2,
It is provided with a thin diaphragm 27 that correctly faces the toothpaste outlet hole 20 of the storage tube main body 19.

The cylinder 26 with the diaphragm 27 is also made of synthetic resin material, and the back of the body has a communication hole 2.
8 is open. 29 is a cap tube 24 facing the bristles 13 of the toothbrush A.
This is a toothpaste drop hole formed at the front end of the back surface of the cylinder 26, and is connected to the communication hole 28 of the cylinder 26.
By communicating with the outflow hole 20 of the storage tube main body 19 through the cap tube 24, an overall flow path P for the toothpaste M is formed inside the cap tube 24.

Further, C is a general term for a pump frame through which the toothpaste M is to be flowed out from the storage tube B, and includes a plunger 30 which is inserted and set into the cylinder 26 in a non-removable manner along the longitudinal center line of the cap tube 24. , continuously from its exposed front end,
The opening/closing bar 31 is bent in a transverse manner to cover the toothpaste drop hole 29 of the cap tube 24, and the storage tube B is also continuous from the exposed front end of the plunger 30 and spaced apart from each other in an L-shape facing each other. A pair of regulating arms 32 are provided that extend rearward along both left and right side surfaces of the vehicle. Furthermore, stopper pieces 33 are also extended outward from the rear end portions of the regulating arms 32.

The pump frame C is also made of a colored synthetic resin material, and as shown in Figs.
On the other hand, the plunger 30 is connected to the cylinder 2.
6, the opening/closing bar 31 is assembled so as to be able to slide in the front and back direction within the

9 will be opened and closed. A compression coil spring 34 always presses the plunger 30 forward to keep the drop hole 29 closed, and is wrapped around the plunger 30 and enclosed within the spring storage chamber S1.

When the plunger 30 slides backward against the spring 34, the inside of the cylinder 26 and the housing tube main body 19 acts as a pump chamber, and the toothpaste M is automatically sucked out due to the pressure change, and the opening is opened. It is designed to be dropped through a drop hole 29.

The accommodation tube B assembled with the pump frame C in this way is inserted and set into the grip tube 11 of the toothbrush A from the rear as a so-called cartridge, allowing the toothbrushing set of the present invention to be assembled. It will be completed as In this state, as shown in FIGS. 13 to 15, the stopper pieces 33 of both regulating arms 32 on the pump frame C engage with the grooves 18 of the grip tube 11 and slide in the front-rear direction. Container tube B
As already mentioned, the slide operation piece 23 engages with the slide guide groove 17 of the grip tube 11.

In addition, in the illustrated example, the grip tube 11 of toothbrush A,
Although the toothpaste storage tube B and the toothpaste storage tube B are made to have a substantially semicircular cross section to fit each other, they may be made to have a circular cross section since there is no risk of relative rotation of the two tubes 11 and B due to the above-mentioned engagement action. Needless to say.

<Operation> When using the toothpaste set of the present invention, while holding the grip tube 11 of the toothbrush A in one hand, place the fingertips of the other hand on the slide operation piece 23 of the toothpaste storage tube B that is exposed from the grip tube 11. Hit it and push it forward.
Then, as is clear from the state changes in FIGS. 13 and 14, the housing tube B will slide against the toothbrush A in the direction in which the bristles 13 exist, and eventually the housing tube B will The stopper piece 33 of the attached pump frame C quickly engages the front end of the split groove 18 in the grip tube 11.

As a result, when the pump frame C temporarily stops, the toothpaste drop hole 29 of the storage tube B is still closed by the opening/closing bar 31 of the pump frame C, as shown in FIG. The drop hole 29 naturally corresponds to the rear end of the brush bristles 13. In other words, in the initially assembled state shown in FIG. Front and rear mutual spacing distance w2 with hole 29
The relationships are set almost equally.

Therefore, the toothpaste storage tube B is further pushed forward from the state shown in FIG. 14 and continues. Then, the stopper piece 3 for the grip tube 11
Although the pump frame C is in a fixed state due to the locking action of No. 3, only the housing pipe B is in the 15th
As the plunger 30 of the pump frame C slides forward as shown in the figure, the plunger 30 of the pump frame C is
When sliding backwards against the compression coil spring 34 to apply a pumping action to the toothpaste M inside the housing tube main body 19, the opening/closing bar 31 of the pump frame C also opens as shown in FIG. , the toothpaste drop hole 2 of the storage tube B
This results in opening 9.

Due to the pressure change caused by the pumping action of the plunger 30 and diaphragm 27, the toothpaste M is automatically sucked out from the housing tube main body 19 through the flow path P, falls from the open drop hole 29, and is brushed by the toothbrush A. It is arranged on the hair 13.
In that case, in the state shown in FIG. 14, the longitudinal mutual spacing w3 between the slide operation piece 23 and the front end of its guide groove 17 is determined to be approximately equal to the distance w4 from the front end to the rear end of the brush bristles 14. Therefore, as the pushing operation is performed from FIG. 14 to FIG.

After the arrangement is completed, the forward pressing force on the storage tube B is released. that way,
Due to the tension of the coil spring 34, the accommodation tube B slides back from the state shown in FIG. 15 to the state shown in FIG. 14,
At the same time, the pumping action by the plunger 30 is stopped, and the toothpaste drop hole 29 is also
As shown in FIG. 12, the pump frame C is automatically closed, so the entire housing tube B with the pump frame C is subsequently pulled back to the rear as shown in FIG. 13.

In this state, the user can grasp the grip tube 11 of the toothbrush A, so it is sufficient to brush the teeth while holding the grip tube 11. In this case, the sliding operation piece 23 of the housing tube B is prevented from accidentally sliding forward due to the worker's hand holding the grip tube 11, so that the toothbrushing work can be carried out easily without any hindrance. I can do it. However, in order to completely prevent such accidental sliding or rattling, in the assembled state shown in FIGS. It is only necessary to set the structure or a separate locking tool so that the lock can be locked in a detachable manner.

In the illustrated embodiment, the toothpaste storage tube B is inserted and set in a so-called cartridge type from the rear of the hollow grip tube 11 in a detachable and replaceable manner.
It is also conceivable to create a configuration in which the rear opening/closing cover 16 of 1 is fixed in a non-removable manner so that the housing tube B does not need to be replaced.

<Effects of the invention> As described above, the toothpaste set of the present invention has a toothbrush A with bristles 13 implanted in the front end of a stay 12 that protrudes forward from a hollow grip tube 11, and a toothpaste M. Accommodation tube body 19 filled with
By attaching the cap tube 24 from the front, the cylinder 26 is restrained and fixed therein, and the cap tube 24 is attached from the front of the housing tube body 19.
A toothpaste storage pipe B is defined with a flow path P that communicates with the toothpaste drop hole 29 of No. 4, and the plunger 30 enters the cylinder 26 of the cap pipe 24 as a pressure state in which the drop hole 29 is normally closed. , and a pump frame C that is inserted and installed so as to slide along the front-rear direction, and sucks out the toothpaste M from the storage tube body 19 and drops it by the pumping action of the plunger 30, and the pump frame C is attached. When the storage tube B is inserted into the grip tube 11 of the toothbrush A so that it can only be slid in the front-rear direction, and is slid forward toward the bristles 13 of the toothbrush A, the cap tube 24 falls into the drop hole. 29 is opened, the toothpaste M is automatically sucked out by the plunger 30 and placed on the brush bristles 13, which has the effect of reliably solving the problem of the prior art described at the beginning.

That is, since the present invention consists of an assembly of the toothpaste storage tube B and the toothbrush A, it is extremely convenient to carry when traveling. In addition, when using it, it is sufficient to slide the toothpaste storage tube B in one direction with respect to the toothbrush A, and by doing so, the appropriate amount of toothpaste M is automatically and reliably applied to the brush bristles 13. In addition to being able to slide the toothpaste in the opposite direction, the grip tube 11 of the toothbrush A can be grasped without any trouble, so the operability of applying the toothpaste and the workability of toothbrushing are excellent, and the so-called one-touch operation is possible. It can be used casually in expressions.

In that case, it is clear from the illustrated embodiment that the toothpaste receiving tube B is connected to the grip tube 11 of the toothbrush A.
On the other hand, if the toothbrush A is set to a so-called cartridge type that can be attached, detached, and replaced, it is even more beneficial because the toothbrush A can be used for a long time.
