Problems solved by technology

[0003] However, this toothbrush manufacturing method has disadvantages in that, since the bristles cannot be reliably fixed to the toothbrush body, the bristles tend to come off from the toothbrush body, and impurities are easily accommodated in the holes formed in the toothbrush head.
However, in this case the problem is that the same number of different toothbrushes have to be manufactured and put on the market
[0007] Second, there is the problem that if an error occurs in even one step in a series of manufacturing steps, all other steps must be stopped
Manufacture must be stopped if an error occurs in even one of the above processes
[0008] Third, the injection molding machine is not running during the placement and heat welding process
However, this bonding method requires an increased area of ​​the head and may cause damage to the toothbrush

Embodiment Construction

[0040] The toothbrush of the present invention includes a pressure relief unit (r) having a plate shape and a size sufficient to cover bristles disposed in the head of the toothbrush.

[0041] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

[0042] Figure 2 is a perspective view of the head insert 10 used in the present invention. The head insert 10 is made of plastic and has a thickness ranging from 1.5 mm to 3.0 mm. If the thickness of the head insert 10 is smaller than the above range, the head insert 10 may be undesirably bent during the heat welding process. If the thickness of the head insert 10 is greater than the above range, the toothbrush head will be too thick.

[0043]The head insert 10 has a through hole 11 therein so that toothbrush bristles can be seated in the through hole 11 . Unlike conventional techniques using filaments, the vias 11 can have different sizes. In other words, the size and s...

Abstract

Disclosed are a toothbrush and a method of producing the same. The toothbrush of the present invention includes a pressure relief unit (r) which is installed in a head part of the toothbrush and has a plate shape and a predetermined size sufficient to cover bristles set in the head part. In the present invention, the head part is thin, and the bristles are set in the head part without using a wire. Furthermore, the present invention is easily adapted for mass production using inexpensive equipment. As well, the pressure relief unit (r), which is installed in the head part, serves as a reinforcing unit. Therefore, the head part is prevented from breaking during use despite having a reduced thickness.

Description

technical field [0001] The present invention generally relates to a toothbrush and a method of manufacturing the same, and more particularly, to a toothbrush having a pressure relief unit installed in a head of the toothbrush and a method of manufacturing the same. Background technique [0002] Typically, to manufacture a toothbrush, first a toothbrush body is manufactured with holes in the head of the toothbrush. Afterwards, place the toothbrush bristles folded in half in the holes in the head. The bristles are secured to the toothbrush body by inserting filaments, which are made of elastic metal and have a length greater than the diameter of the hole, into the holes. [0003] However, this toothbrush manufacturing method has disadvantages in that the bristles tend to come off from the toothbrush body because the bristles cannot be securely fixed to the toothbrush body, and impurities are easily accommodated in holes formed in the toothbrush head. Furthermore, this toothb...
