Description

[Detailed Description of the Invention] This invention relates to an improvement of a portable toothbrush in which the entire length of the toothbrush is slidably housed in a case.

In general, toothbrushes have long handles that are inconvenient to carry, so in recent years toothbrushes have been made with double-layered inner and outer handles that are expandable and retractable (Utility Model Application No. 108177/1983). (Refer to Japanese Patent Application Laid-Open No. 53-75-75), none of these had any effective measures taken to ensure the sealing of the brush part when stored, so unless stored in a separate case etc., it should be carried hygienically. In addition, there were other problems such as the large diameter of the rear handle, which was gripped, and did not fit comfortably in the hand, making it difficult to operate the toothbrush smoothly.

In view of these circumstances, the present invention consists of a handle and an expanded storage chamber on one side, and a case that accommodates the entire length of the toothbrush is molded from plastic material, and the opening of the storage chamber is closed with a piece of lid. While the case can be opened and closed freely, a guide groove is provided from the open end of the case to the handle, and the handle of the toothbrush is slidably and tightly fitted into the guide groove, ensuring hygiene when carrying the toothbrush. It is an object of the present invention to provide a new portable toothbrush that also has good operability.

Hereinafter, the structure of the present invention will be explained in more detail based on the embodiment shown in the drawings. 1 is a toothbrush equipped with a flocked part 1' and a relatively short and small handle part 1'', 2 is a toothbrush with a shape that can store the toothbrush in its entirety. The case is made of plastic, and the bristles 1' are provided on one side of the handle 2'' into which the handle 1'' of the toothbrush is inserted.
The storage chamber 2' is integrally expanded, and a guide 12'' is provided through which the handle 1'' of the toothbrush can slide between the storage chamber 2' and the handle 2''.

The shape of the guide groove structure of the case 2 is not particularly limited as long as it can slide in close contact with each other, but for example, as shown in FIG. While providing a dovetail groove 3 inside the handle 2″,
By forming the handle 1'' of the toothbrush into an inverted trapezoidal shape that matches the dovetail groove 3, the two can be engaged with each other using the elasticity peculiar to the plastic material that constitutes the case.

In this case, it goes without saying that by slightly narrowing the groove width of the guide 12'' on the opening side of the storage chamber, it is possible to prevent the two from coming apart and to further improve their connectivity. .

Note that 4 in the figure indicates a lid piece provided at the end of the storage chamber 2' of the case 2.

When using the portable toothbrush of the present invention having the above structure, the toothbrush 1 is pulled out a certain length from the case 2 as shown in FIG. Because they fit tightly together, there is no chance of them coming loose or loose, and the handle 1" and handle 2"
By grasping the handle 2'' while placing your thumb on the lower surface of the storage chamber 2' that protrudes downward midway between the toothbrush and the toothbrush, you can grip the handle 2'' more stably, making it easier to operate the toothbrush than with conventional products. is extremely good.

Furthermore, after using the toothbrush of the present invention, simply push the toothbrush into the case, and the handle 1'' will be inserted into the handle 2'' by sliding through the guide groove 2'' consisting of a dovetail groove or the like. At the same time,
Since the flocked part 1' is completely housed in the storage chamber 2' of the case, the lid piece 4 provided at the opening of the storage chamber is elastically fitted and locked to the opening. The entire toothbrush can be stored inside the case.

As mentioned above, according to the portable toothbrush of the present invention, it can be assembled and stored with a simple operation of pulling out or pushing the toothbrush out of the case, and its total length can be shortened to approximately half. Not only is it convenient to carry when traveling, but the entire toothbrush is sealed, making it extremely hygienic.
It offers excellent practicality that could not be expected from conventional portable toothbrushes of this type.
