Abstract

The present invention relates to a method of manufacturing a toothbrush. The method is capable of manufacturing a high quality toothbrush which not only can increase combined durability by double injection of two materials, but also improves appearance of the toothbrush by inserting a decorative member formed of one material selected from PET, SAN and PS materials into an inner handle part of a toothbrush stick manufactured by injection molding an ordinary PP material, and double injection molding the handle part and the decorative member to manufacture the toothbrush in such a form that one surface, front and rear surfaces, left and right surfaces or the front, rear, left and right surfaces among front, rear, left and right surfaces of the decorative member are exposed, thereby applying the decorative member formed of one material selected from the PET, SAN and PS materials that could not be easily externally attached.

Description

칫솔 제조방법{A manufacturing method of toothbrush}[0001] A manufacturing method of toothbrush [0002]

본 발명은 칫솔 제조방법에 관한 것으로, 더욱 상세하게는 사출성형시 상호 합체되지 않는 물성을 갖는 폴리프로필렌(PP, Polypropylene) 소재과 폴리에틸렌 테레프탈레이트(PET, Polyethylene Terephthalate) 소재를 합체하여 하나의 칫솔대를 사출형성할 수 있는 칫솔 제조방법에 관한 것이다.The present invention relates to a toothbrush manufacturing method, and more particularly, to a toothbrush manufacturing method which comprises combining a polypropylene (PP) material and a polyethylene terephthalate (PET) material having physical properties that are not mutually coalesced during injection molding, The present invention relates to a method of manufacturing a toothbrush.

주지하는 바와 같이 칫솔(toothbrush)은 남녀노소 구강의 위생과 잇몸질환발생을 억제시키는 용도에서 오래전부터 사용되어 오고 있는 생활필수품 중 하나이다.As is known, toothbrush is one of life necessities that have been used for a long time in the use of inhibiting the hygiene and gum disease occurrence in both oral and oral mouth.

대략적인 칫솔대의 형태는 칫솔모가 식재된 헤드부, 헤드부로부터 연장되는 손잡이부로 이루어지며, 칫솔대의 손잡이는 성형이 용이하고 텐션이 좋은 PP(폴리프로필렌, polypropylene) 또는 투명성과 강성이 뛰어난 PET(페트, polyethylene terephthalate)소재로 제작되며, 헤드부에 다수개 마련된 식모공에는 설정된 개수의 칫솔모가 식재된다. The approximate shape of the toothbrush body is composed of a head portion having bristles and a handle portion extending from the head portion. The handle of the toothbrush handle is made of PP (polypropylene), which is easy to mold and has good tension, or PET , polyethylene terephthalate), and a plurality of bristles are provided in the head portion, and a predetermined number of bristles are planted.

한편, 상기 칫솔대에 있어, PP소재의 칫솔대는 최근 그 디자인과 칫솔대를 쥐는 파지감을 향상시키기 위한 목적에서 탄력이 있는 무독성 우레탄계열의 고무소재를 합체하여 제작되어 사용되기도 한다.On the other hand, in the toothbrush holder, a toothbrush of a PP material is recently manufactured by combining a rubber material of a non-toxic urethane type having elasticity for the purpose of improving the grip and grip feeling of the toothbrush body.

상기 무독성 우레탄계열의 고무소재는 PP소재로 된 칫솔대에 부착성이 뛰어나기 때문에 칫솔대의 제작이 뛰어나나 투명도가 낮기 때문에 고급스러움은 떨어진다.Since the non-toxic urethane-based rubber material is excellent in adhesion to a toothbrush body made of PP material, the toothbrush body is excellent in manufacturing and low in transparency.

또한, 상기와 같이 무독성 우레탄계열의 고무소재가 합체된 칫솔대의 경우 칫솔의 전반적인 무게를 가중시키고, 칫솔대의 손잡이부 두께가 비교적 굵게 제작되어 파지감이 떨어지는 단점이 있다.In addition, in the case of the toothbrush body incorporating the non-toxic urethane-based rubber material as described above, the overall weight of the toothbrush is increased, and the thickness of the handle of the toothbrush body is relatively thick.

참고로 상기 PP(폴리프로필렌, polypropylene)은 프로필렌의 중합체. 내약품성, 기계적 성질, 열적 성질도 우수하며, 천연가스로부터 풍부하게 얻어지는, 에틸렌과 비슷하고 탄소 원자가 하나 많은 프로필렌을 중합시키면 폴리에틸렌보다 투명하고 굴절에 강하여 다양한 성형용품의 소재로 사용된다.For reference, the PP (polypropylene) is a polymer of propylene. It has excellent chemical resistance, mechanical properties and thermal properties. It is rich in natural gas, similar to ethylene, and has one more carbon atom. When it is polymerized, it is more transparent than polyethylene and strong against refraction.

한편, PET(polyethylene terephthalate)소재는, 테레프탈산과 에틸렌글리콜을 중축합하여 얻을 수 있는 포화폴리에스테르로서, 폴리 에틸렌 테레프탈레이트는 폴리 부틸렌 테레프탈레이트보다 분자쇄의 길이가 짧고 잘 휘어지지 않는 구조이므로 강성, 내열성 등이 좋은 소재로 상기와 같은 칫솔대를 제작하여 사용하기도 한다. On the other hand, PET (polyethylene terephthalate) material is a saturated polyester obtained by polycondensing terephthalic acid and ethylene glycol. Since polyethylene terephthalate has a structure in which molecular chain is shorter than polybutylene terephthalate and does not bend well, Such a toothbrush body may be manufactured and used with a material having good heat resistance and the like.

또한, SAN 수지(Styrene Acrylonitrile Copolymers)는, 방향족탄화수소인 스타이렌과 불포화나이트릴인 아크릴로나이트릴을 중합시켜 만든 혼성중합체로서, 투명도, 열변형성, 내화학성, 광택성 등이 뛰어나서 냉장고의 육류와 체소 보관 서랍, 혼합용기 등과 같은 가정용품 성형에 널리 사용된다.SAN resin (styrene acrylonitrile copolymers) is a copolymer made by polymerizing styrene, an aromatic hydrocarbon, and acrylonitrile, which is an unsaturated nitrile, and is excellent in transparency, heat change, chemical resistance and gloss, It is widely used for household articles such as sowing storage drawers, mixing containers and the like.

PS(Polystyrene) 소재는, 열가소성 플라스틱으로 투명한 플라스틱 용기, 가정용품, 인테리어 장식품, 완구 및 사무용품 등에 널리 사용된다.PS (Polystyrene) material is widely used for transparent plastic containers, household goods, interior ornaments, toys, and office supplies by thermoplastics.

상기와 같은 PET. SAN 수지 및 PS 소재로 성형된 칫솔대는 투명성과 색상을 겸비하여 칫솔대로 사용하기에 좋은 강도를 가지고, 양치 후에 세척이 뛰어난 이점이 있고, 외관상 클리어한 고급스러움을 제공하지만, 식모공에 칫솔모를 식재하기 위한 제작과정에서 식모공이 깨지는 등의 불량사례가 잦은 단점이 있어, 완성품의 가격은 PP소재로 제작된 칫솔에 비하여 고가로 판매되고 있다.The PET as described above. The toothbrush made of SAN resin and PS material combines transparency and color, has good strength to use as a toothbrush, has an advantage of washing after tooth brushing, provides a clean appearance, but bristles are planted in the pores The cost of the finished product is higher than that of the toothbrush made of the PP material because there are disadvantages such as breakage of the food pores in the manufacturing process.

칫솔 관련 선원기술을 살피면, 대한민국 실용신안공고 20-1986-0002647(명칭: 치솔, 공고일자 1986년 10월 15일, 이하 이를 특허문헌이라 칭함)가 개시되어 있다.When referring to the toothbrush related source technique, Korean Utility Model Application Publication No. 20-1986-0002647 (entitled: toothbrush, published on Oct. 15, 1986, hereinafter referred to as patent document) is disclosed.

상기 특허문헌은 칫솔 몸체에 홈을 형성시키고 여기에 색채와 형상을 갖는 덮개를 삽입하여 제작된 것으로 덮개부분만을 다르게 형성함으로써, 몸체와 다른 색상을 갖도록 한 칫솔을 제공하도록 하였다.The above-mentioned patent document provides a toothbrush which is formed by forming a groove in a toothbrush body and inserting a lid having a color and a shape into the toothbrush body, and by forming only a lid part differently, the toothbrush having a color different from that of the body is provided.

하지만, 상기와 같은 칫솔은 홈에 맞는 덮개를 끼워 삽입 고정하는 방식으로 칫솔의 오랜 사용 중 쉽게 덮개가 홈으로부터 이탈할 수 있는 문제점이 있고, 가령 덮개의 이탈 후에는 몸체의 손잡이 부분의 내구성이 떨어지는 단점이 있었다.However, the above-described toothbrush has a problem in that the cover can be easily detached from the groove during long use of the toothbrush in such a manner that the toothbrush is inserted and fixed by fitting a lid fit to the groove. Thus, after the lid is released, There were disadvantages.

특히 PP - PET, PP - SAN 또는 PP - PS 등 두 가지 소재의 단순부착 혹은 삽입에 의한 결합은 칫솔대의 손잡이로 적합하지 못하기 때문에 최근에는 PP 소재에 쉽게 부착이나 조합될 수 있는 우레탄계열의 고무소재의 이중성형제작된 칫솔만이 유통되고 있는 실정이다. Especially, the bonding by insertion or insertion of two materials such as PP - PET, PP - SAN or PP - PS is not suitable as a handle of a toothbrush. Recently, urethane rubber Only the toothbrush manufactured by the double molding of the material is circulated.

본 발명은 상기와 같이 제반되는 종래의 문제점을 해결하기 위하여 발명한 것으로서,그 목적은 폴리프로필렌(PP) 소재와 페트(PET) 소재, 폴리프로필렌(PP) 소재와 산(SAN) 수지 또는 폴리프로필렌(PP) 소재와 피에스(PS) 소재 중 어느 하나의 소재쌍을 합체 성형하여 하나의 칫솔대를 형성함으로써, 서로 다른 소재가 주는 질감의 제공으로 나일론, 고무소재 등의 칫솔모 식재에 따른 불량률을 최소화하면서 칫솔의 외관미, 강도 향상은 물론, 고급스러운 칫솔을 제조할 수 있는 칫솔 제조방법을 제공하는 것이다.SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a polypropylene (PP) material and a PET material, a polypropylene material and a SAN resin, (PP) material and a PS (PS) material to form a single toothbrush body, thereby providing a texture imparted by different materials, thereby minimizing the defective rate due to the bristle materials such as nylon and rubber materials It is an object of the present invention to provide a toothbrush manufacturing method capable of manufacturing a luxurious toothbrush, as well as improving the appearance and strength of the toothbrush.
