Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. However, the spirit of the present invention is not limited to the presented embodiments, and those skilled in the art who understand the spirit of the present invention may add, change, or delete other components within the scope of the same spirit, or create other degenerative inventions or this invention. Other embodiments that are included within the scope of the invention can be easily proposed, but this will also be said to be included within the scope of the invention of the present application.

In addition, components having the same function within the scope of the same idea shown in the drawings of each embodiment will be described using the same reference numerals.

Figure 1 shows an oral care device according to an embodiment of the present invention, (a) is a perspective view, (b) is a front view, and (c) is a left side view.

The oral care device 100 according to an embodiment of the present invention is made of polypropylene (PP, polypropylene), polyethylene terephthalate (PET, polyester terephthalate), polyoxymethylene (POM), and polyketone ( It is manufactured using plastic synthetic resin materials such as PK, polyketone) and polybutylene terephthalate (PBT, polybutylene terephthalate) or steel-based materials, and the handle part that the user holds with his or her hand is composed of three straight and curved lines. am.

This is one of the main characteristic structures presented in the present invention. Instead of adopting the slide injection method, the oral care device 100 forms a three-dimensional space in which one line is separated into three lines, which are then connected to each other at the end of the handle. It is formed in a structure that is integrated and finished, which can greatly improve the user's grip.

In addition, the oral care device 100 has a three-dimensional structure in which the handle portion is open on the front, back, and sides, so 20% to 40% less material is required during production, which not only saves material, but also reduces plastic. It is possible to minimize environmental pollution by reducing synthetic resin materials.

In addition, the oral care device 100 can be manufactured through a general injection molding method without the need to use a slide mold method when the handle portion is formed into a three-dimensional open shape through three lines, so mass production is possible.

In other words, the oral care device 100 applied to the present invention can be manufactured using a general injection molding method when manufacturing the handle portion formed of three lines, so the production quantity can be greatly increased compared to manufacturing using the slide mold method. This is possible (see Figure 3).

In addition, the oral care device 100 can be used in various ways, such as having a head made of toothbrush bristles or a tongue cleaner.

For example, the head portion is formed with a separate binding structure so that the user can replace it with an oral care member including toothbrush bristles or a tongue cleaner depending on the intended use.

If the structure is described in more detail with reference to FIG. 1, the oral care device 100 applied to the present invention includes a handle portion 110, a neck portion 120, a head portion 130, etc. .

The handle portion 110 is formed by connecting one side (the upper side in the drawing) to the neck portion 120 with one line, and the portion below it where the user's hand grips is in the form of a straight line or curve. It is divided into a total of three lines, including one first line 111 and two curved second lines 112.

In this way, the handle portion 110 is formed by being separated into three straight and curved lines, thereby forming a three-dimensional space in which the inside is open left and right and top and bottom based on the drawing.

In addition, since the handle portion 110 may be partially or entirely formed of an elastic material, when the user uses the oral care device 100, the user can control the pressure of the hand that holds the oral care device 100, thereby protecting the teeth, gums, etc. It is possible to easily clean the hard-to-reach areas behind the molars.

That is, the first line 111 and the second line 112 are made of an elastic material so that they can be freely contracted or expanded by the force of the user holding them.

In addition, the handle portion 110 can be formed by integrally combining the ends of the parts separated by three straight and curved lines (i.e., the lowest part in the drawing) to form a single line.

For example, the ends of the first line 111 formed in the center and the ends of the second lines 112 formed on both sides of the first line 111 can be recombined into one line for finishing. By combining these three lines again, it becomes possible to improve the user's grip through the empty space inside and the elasticity of the handle.

Additionally, the handle portion 110 may form an anti-slip portion 113 to prevent the user's hand holding the handle from slipping.

As an example, the anti-slip part 113 is located on the outside of the part connected to the neck part 120 by one line, the outside of the first line 111, the outside of the second line 112, or a combination thereof. It can be formed to protrude.

At this time, the anti-slip portion 113 prevents slipping by forming protrusions at predetermined intervals up, down, left, and right, or by forming various text (e.g., company name or promotional text) to protrude through transfer printing, gold leaf, silk printing, etc. It can be prevented. In other words, by making the product name or company name protrude, the promotional effect can be increased in addition to the original slip prevention.

The neck portion 120 is a long and thin portion that connects the handle portion 110 and the head portion 130.

The head portion 130 is a portion provided with oral care members such as toothbrush bristles or tongue cleaner.

At this time, when the oral care device 100 is configured in the form of a toothbrush, the head portion 130 may include a bristle groove 131 on one side into which the toothbrush bristles are inserted at a certain depth.

Meanwhile, the head portion 130 can replace oral care members including the first brush bristles or tongue cleaner depending on the user's usage type.

It is also possible to configure the two second lines 112, which are curved in each direction, to protrude from each other.

Figure 3 is a diagram for explaining the structure between the width of the first line constituting the handle portion of the oral care device applied to the present invention and the space width between the second lines.

As shown in Figure 3, the oral care device 100 applied to the present invention must have a specific and precise design of the handle portion 110 in order to facilitate manufacturing and mass production.

As an example, in the present invention, the width (left and right in the drawing) of the first line 111 of the handle portion 110 is divided into the second lines 112 formed to protrude on both sides of the first line 111. It is designed to be smaller than or equal to the width of the space between spaces. That is, the first line 111 and the second line 112 must be designed to have a structure that does not overlap each other.

If the width of one first line 111 provided in the center is designed to be larger than the width of the space between the two second lines 112, a separate device such as a slide must be used when manufacturing the product, so mass production This is because it is difficult and scratches may occur during production.

Figure 4 is a diagram showing a hanging hole structure applied to an oral care device according to an embodiment of the present invention.

As shown in Figure 4, the oral care device 100 applied to the present invention may be additionally configured with a hanging hole 140 to facilitate drying and storage.
