본 발명은 칫솔에 관한 것으로, 보다 상세하게는 잇몸 맛사지 기능을 하는 연질탄성체가 형성된 칫솔에 관한 것이다.The present invention relates to a toothbrush, and more particularly to a toothbrush formed with a soft elastic body to function as a gum massage.

일반적인 칫솔은 손잡이부와, 상기 손잡이부로부터 연장하여 형성된 목부 및 상기 목부와 연결되며 합성수지재의 칫솔모들이 삽입장착된 헤드부로 이루어진다. 이와 같은 단순한 칫솔은 딱딱한 치아 표면의 세정력은 우수하나 치아를 감싸고 있는 잇몸을 맛사지하는 경우에는 칫솔모의 재질 특성상 단단하여 잇몸을 상하게 하는 문제점이 있다.A general toothbrush comprises a handle portion, a neck portion extending from the handle portion, and a head portion connected to the neck portion and into which bristles of a synthetic resin material are inserted and mounted. Such a simple toothbrush has excellent cleaning power on the hard tooth surface, but when massaging the gums surrounding the teeth, there is a problem of hardening the gums due to the nature of the bristles.

이와 같은 문제점을 해결하기 위하여, 근래에는 칫솔의 칫솔헤드에 고무와 같은 연질탄성체를 사출성형시켜 잇몸을 안전하게 맛사지할 수 있는 칫솔이 제안되어 사용되고 있다.In order to solve such a problem, in recent years, a toothbrush which can safely massage the gum by injection molding a soft elastic material such as rubber on the toothbrush head of the toothbrush has been proposed and used.

하지만, 이러한 칫솔은 연질탄성체를 형성시키기 위해 헤드부의 외측에 사출성형을 위한 게이트를 마련하고 외측으로부터 연질탄성체의 용융체를 사출하여 형성(용융체가 칫솔헤드를 감싸면서 연질탄성체를 형성시킴)하므로 일반적인 칫솔에 비하여 칫솔헤드가 커질수 밖에 없으며, 이로 인하여 치아 세정효과가 떨어지게 되는 문제점이 있다.However, these toothbrushes are formed by providing a gate for injection molding on the outside of the head portion to form a soft elastic body and by injecting a melt of the soft elastic body from the outside (the melt forms a soft elastic body surrounding the toothbrush head). Compared to the toothbrush head is larger than this, there is a problem that the tooth cleaning effect is reduced.

따라서, 본 발명은 상기의 문제점을 해결하기 위하여 창출된 것으로서, 본 발명의 목적은 칫솔질시 칫솔헤드판 및 칫솔의 헤드로부터 잇몸과 치아가 보호되도록 한 칫솔을 제공하는데 있다.
본 발명의 또 다른 목적은, 보호패드가 칫솔헤드판으로부터 이탈되지 않도록 한 칫솔을 제공하는데 있다.

본 발명 칫솔의 다른 특징은, 상기 이탈방지수단은, 상기 칫솔헤드판에 형성되는 이탈방지통로들과, 상기 이탈방지통로들에 결합되고 상기 보호패드에 연결되어 상기 보호패드를 상기 이탈방지통로에 고정시키는 결합부재로 이루어진다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a toothbrush to protect the gums and teeth from the toothbrush head plate and the head of the toothbrush when brushing.
Another object of the present invention is to provide a toothbrush which prevents the protective pad from being separated from the toothbrush head plate.
The toothbrush of the present invention for achieving the above object is a toothbrush provided with a toothbrush head plate having bristles on the toothbrush head end of the handle, a protective pad provided around the toothbrush head plate to protect the teeth and gums when brushing ; And a separation prevention means provided between the protective pad and the toothbrush head plate to support the protective pad on the toothbrush head plate.

The fusion surface 15 and the fusion side surface 15 'of the toothbrush head plate 1 may be bonded to the head plate fusion surface 22 and the head plate fusion side surface 22' of the toothbrush head portion 21. At this time, the non-fixed bristle 6 will also be adhered because the end is melted. It is preferable to use an adhesion method using ultrasonic waves.

이제 본 발명의 실시예에 따른 잇몸 맛사지용 연질탄성모(71)와 잇몸 보호용 보호패드(80)가 형성된 칫솔의 제조공정을 자세히 살펴본다.Now look at the manufacturing process of the toothbrush formed with soft elastic hair 71 and gum protection protection pad 80 for gum massage according to an embodiment of the present invention.

본 발명에 따른 칫솔의 제조공정은 제 1 단계로서, 먼저 칫솔헤드판(1)과, 칫솔손잡이(2)를 따로 플라스틱 사출 성형하는 플라스틱 성형단계로부터 시작된다. 플라스틱 성형단계는 종래의 일반 플라스틱 성형물 제작과 동일한 방식으로 그 결과물은 도 1a 와 도 2에 도시된 바와 같은 형태가 되며 그 형상 구조는 앞서 상세히 설명한 바와 같다. 필요에 따라, 칫솔손잡이(2)에는 천연고무나 합성고무를 이중 사출하여 잡기 편하고 미끄러지지 않게 하는 것이 좋다. 이또한 일반적인 방법이므로 자세한 설명은 생략한다.The manufacturing process of the toothbrush according to the present invention is a first step, which starts with a plastic molding step of first plastic injection molding the toothbrush head plate 1 and the toothbrush handle 2 separately. The plastic molding step is the same as the conventional plastic molding production, the result is the shape as shown in Figure 1a and 2 and the shape structure is as described in detail above. If necessary, the toothbrush handle 2 is preferably double injection of natural rubber or synthetic rubber to be easy to grip and to prevent slipping. Since this is also a general method, detailed description thereof will be omitted.

제 2 단계는 칫솔헤드판(1)에 연질탄성모와 보호패드를 성형하는 연질체 성형단계로서, 먼저 성형된 칫솔헤드판(1)을 금형에 넣고 유동체를 칫솔헤드판(1)의 융착면(15) 상에 형성된 관통홈(14), 연결홈(18)으로 사출시켜 이를 따라 이와 연결된 연질탄성모구(13) 및 테두리홈(17)을 따라 유동체를 공급시키고 냉각시킴으로써 연질탄성모(71)와 보호패드(80)를 형성시킨다.The second step is a soft body molding step of forming a soft elastic hair and a protective pad on the toothbrush head plate 1. First, the molded toothbrush head plate 1 is put into a mold, and the fluid is fused to the toothbrush head plate 1 ( 15 is injected into the through grooves 14 and the connection grooves 18 formed on the soft elastic hairballs 13 and the rim grooves 17 connected thereto, thereby supplying and cooling the fluid along the soft elastic hairs 71. The protective pad 80 is formed.

제 3 단계는 칫솔헤드판(1)의 칫솔모식모구(11)에 칫솔모(60)을 식모하는 식모 단계로서, 일반적으로 사용하는 공지의 식모기를 사용하여 칫솔모(60)을 식모한다. 본 단계에서 칫솔모(60)는 칫솔헤드판(1)에 완전히 고정된 것이 아니라 끼워져 있는 상태이다.The third step is a hair transplant step in which the bristles 60 are implanted in the bristle hatch 11 of the toothbrush head plate 1, and the bristles 60 are planted using a conventionally used well-equipped funnel. In this step, the bristles 60 are not completely fixed to the toothbrush head plate 1 but are fitted.

제 4 단계는 연질탄성모(71)와 보호패드(80)가 성형되고 칫솔모(60)가 식모된 칫솔헤드판(1)을 칫솔손잡이(2)의 칫솔헤드부(21)에 융착시키는 융착단계로서, 초음파 용접기를 이용하여 칫솔헤드판(1)의 융착면(15)과 융착측면(15') 및 칫솔헤드부(21)의 헤드판융착면(22) 및 헤드판융착측면(22')를 견고하게 결합시키는 것이다. 물론 다른 방법으로 칫솔헤드판(1)을 칫솔헤드부(21)에 융착시키는 것도 가능하나 매끈하고 견고한 결합을 이루기에는 초음파 용접 방법이 바람직하다. The fourth step is a fusion step of fusion welding the toothbrush head plate 1, in which the soft elastic hair 71 and the protection pad 80 are molded and the bristle hair 60 is planted, to the toothbrush head portion 21 of the toothbrush handle 2. By using an ultrasonic welding machine, the fusion surface 15 and the fusion side surface 15 'of the toothbrush head plate 1 and the head plate fusion surface 22 and the head plate fusion side surface 22' of the toothbrush head portion 21 are used. It is to firmly combine. Of course, it is also possible to fuse the toothbrush head plate (1) to the toothbrush head portion 21 in another way, but to achieve a smooth and solid coupling, the ultrasonic welding method is preferred.

마지막으로, 이와 같이 칫솔헤드판(1)을 칫솔헤드부(21)에 융착시키는 과정에서 칫솔모(6)의 끝부분도 용융되어 응착되어 단단히 고정되게 된다. 이후 칫솔모(6)의 길이를 고르게 절단하고 치아와 닿는 부분을 연마가공하여 마무리하는 마름질단계를 거쳐 칫솔을 완성하게 되는 것이다.Finally, in the process of fusing the toothbrush head plate 1 to the toothbrush head 21, the tip of the bristle 6 is also melted and adhered to be firmly fixed. After that, the toothbrush 6 is cut evenly, and the toothbrush is finished through a finishing step of polishing and finishing the part in contact with the tooth.

상기와 같이 본 발명은, 칫솔헤드판 전방에 보호패드 및 이 보호패드를 칫솔헤드판에 고정시키는 이탈방지수단이 더 구비되므로 칫솔질시 칫솔헤드판 또는 칫솔의 헤드가 잇몸이나 치아에 직접 부딪히는 것을 방지하여서, 이들에 의한 잇몸 손상, 치아 손상을 방지시키게 되며, 보호패드와 칫솔헤드판 사이에 구비된 이탈방지수단에 의해 칫솔을 장기간 사용하여도 보호패드가 칫솔헤드판으로부터 이탈되는 것이 방지된다.As described above, the present invention further includes a protective pad and a separation prevention means for fixing the protective pad to the toothbrush head plate in front of the toothbrush head plate, thereby preventing the toothbrush head plate or the head of the toothbrush from directly hitting the gum or teeth when brushing. This prevents gum damage and tooth damage caused by these and prevents the protective pad from being detached from the toothbrush head plate even when the toothbrush is used for a long time by the separation prevention means provided between the protective pad and the toothbrush head plate.
