Description

에어리스타입 디스펜서의 피스톤구조 {Piston of Airless type dispenser}Piston Structure of Airless Type Dispenser {Piston of Airless type dispenser}

본 고안은 에어리스타입 디스펜서의 피스톤구조에 관한 것으로서, 좀 더 상세히는 내용물의 성분과의 트러블을 해소하여 작동불량을 방지할 수 있는 새로운 구조의 에어리스타입 디스펜서의 피스톤구조에 관한 것이다.The present invention relates to a piston structure of an airless type dispenser, and more particularly, to a piston structure of a new structure of the airless type dispenser, which can prevent malfunction by eliminating trouble with the components of the contents.

화장품이나 기타 내용물을 공기의 압력에 의해 일정량씩 토출하여 사용하는 디스펜서에는 딥튜브에 의해 내용물이 흡입, 토출되고 용기 내에는 그만큼 공기가 유입되는 딥튜브방식과, 용기 내부의 공기가 진공으로 됨에 따라 피스톤이 상승하여 내용물을 밀어내는 에어리스타입으로 대별된다. 도 1은 종래의 이러한 에어리스타입 디스펜서의 구조를 보여준다. 도시된 바와 같이, 용기(11)의 상단에는 디스펜서캡(12)이 씌어진다. 이 디스펜서캡(12)은 펌핑부(14)와 버튼부(15) 및 노즐(16)을 포함한다. 그리고, 용기(11) 내부에는 피스톤(18)이 밀봉적으로 구비된다. 종래에 이러한 디스펜서용 피스톤(18)은 주로 폴리에틸렌수지(PE)로 제작하였다. 그 이유는, PE는 유연성이나 탄성이 우수하여 용기 내벽과의 사이에 기밀성이 유지되고, 아울러, 자체의 윤활작용이 우수하여 원활하게 미끄러질 수 있기 때문이다.The dispenser that dispenses cosmetics or other contents by a certain amount by the pressure of air has a dip tube method in which the contents are sucked and discharged by a dip tube and the air flows into the container, and the air inside the container is vacuumed. It is roughly classified as an airless type in which the piston rises and pushes the contents out. 1 shows the structure of such a conventional airless type dispenser. As shown, the dispenser cap 12 is written on the top of the container (11). The dispenser cap 12 includes a pumping portion 14, a button portion 15, and a nozzle 16. And the piston 18 is provided in the container 11 sealingly. Conventionally, such a dispenser piston 18 is mainly made of polyethylene resin (PE). The reason for this is that PE is excellent in flexibility and elasticity, so that airtightness is maintained between the inner wall of the container and, in addition, it is excellent in lubrication of itself and can slide smoothly.

그런데, 종래의 이러한 PE제 피스톤(18)은 특정한 종류의 화장품성분으로 함유될 수 있는 피그먼트 분산제와 반응을 일으키면 트러블을 초래할 수 있다. 즉, 파운데이션이나 메이크업베이스 등에 사용되는 피그먼트 분산제가 이 PE제 피스톤에 침투하여 팽창되는 현상(스웰링현상)을 일으켜서, 피스톤(18)이 용기(11) 내벽을 따라 원활하게 미끄러질 수 없거나, 균일하지 못한 팽창으로 인한 기밀성의 파괴 등, 디스펜서의 성능에 치명적인 결함을 초래하기도 한다. 이와같이, 종래의 PE제 피스톤은 팽창성(피그먼트 분산제가 침투되어 팽창되는 성질)이 높아서 디스펜서 제품 하자의 원인이 되었다.However, such a conventional PE piston 18 may cause trouble when it reacts with the pigment dispersant, which may be contained in a certain kind of cosmetic components. That is, the pigment dispersant used in the foundation, makeup base, etc. penetrates and expands the piston made of PE (swelling phenomenon), so that the piston 18 cannot slide smoothly along the inner wall of the container 11 or is uniform. It can also cause fatal defects in the dispenser's performance, such as the loss of airtightness due to inadequate expansion. As described above, the conventional piston made of PE has high expandability (property in which the pigment dispersant penetrates and expands), which causes a defect in the dispenser product.

본 고안은 전술한 바와 같은 종래의 에어리스타입 디스펜서의 문제점에 착안하여 제안된 것으로서, 화장품의 내용물과의 트러블로 인한 문제점을 해소하여 작동불량을 방지할 수 있는 새로운 구조의 에어리스타입 디스펜서용 피스톤을 제공하고자 하는 것이다.The present invention has been proposed in view of the problems of the conventional airless type dispenser as described above, and provides a piston for the airless type dispenser of a new structure that can prevent the malfunction by solving the problem caused by the trouble with the contents of the cosmetic. I would like to.

본 고안에 따르면, 용기(11)의 상단 개구부에 디스펜서캡(12)이 결합되고, 이 디스펜서캡(12)은 펌핑부(14)와 버튼부(15) 및 노즐(16)을 포함하며, 용기(11)의 내부에는 피스톤(18)이 끼워진 에어리스타입 디스펜서에 있어서, 상기 피스톤(18)은 피스톤의 본체를 이루는 본체(19)와, 상기 본체(19)의 가장자리에 결합 또는 부착되는 테두리부재(20)로 이루어지고, 상기 본체(19)는 상기 테두리부재(20)보다 팽창성이 낮은 재료로 구성된 것을 특징으로 하는 에어리스타입 디스펜서의 피스톤구조가 제공된다.According to the present invention, the dispenser cap 12 is coupled to the upper opening of the container 11, and the dispenser cap 12 includes a pumping part 14, a button part 15, and a nozzle 16, and the container In the airless type dispenser in which the piston 18 is fitted, the piston 18 includes a main body 19 constituting the main body of the piston and an edge member coupled or attached to an edge of the main body 19. 20, the main body 19 is provided with a piston structure of the airless type dispenser, characterized in that made of a material having a lower expandability than the rim member 20.

이하에서 도면을 참조하여 본 고안의 바람직한 실시예를 설명한다. 도 2는 본 고안의 일 실시예의 사시도로서, 도시된 바와 같이, 용기(11)의 상단 개구부에 디스펜서캡(12)이 결합되고, 이 디스펜서캡(12)은 펌핑부(14)와 버튼부(15) 및 노즐(16)로 구성되며, 용기(11)의 내부에는 피스톤(18)이 밀봉적으로 슬라이딩가능하게 구비되는 것은 종래의 것과 동일하다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. Figure 2 is a perspective view of an embodiment of the present invention, as shown, the dispenser cap 12 is coupled to the top opening of the container 11, the dispenser cap 12 is the pumping unit 14 and the button unit ( 15) and the nozzle 16, and the inside of the container 11, the piston 18 is provided with a sealably slidably the same as the conventional one.

그런데, 이 피스톤(18)은 본체(19)와 테두리부재(20)로 분할 제작되어 서로 결합된다. 이 본체(19)와 테두리부재(20)는 서로 다른 이질재료로 제작된다. 바람직하게는 상기 본체(19)는 테두리부재(20)보다 팽창성, 즉, 스웰링특성이 낮은 재료로 성형하고, 테두리부재(20)는 기밀성이나 윤활성이 우수한 소재로 제작한다. 테두리부재(20)로는 종래부터 피스톤재료로 사용되어 온 연질탄성의 폴리에틸렌수지가 적합하다. 그리고, 본체(19)에 바람직한 재료는 폴리프로필렌(PP)수지, 아크릴로니트릴-스티렌(SAN)수지, 포화폴리에스테르 계열의 PET나 PETG 또는 PCTG 등이다. 이러한 수지들은 폴리에틸렌수지에 비해 상대적으로 기밀성이나 윤활성은 낮으나, 이점은 직접 용기(11)의 내벽에 접촉되지 않으므로 트러블을 일으키지 않으며, 한편, 화장품 내용물을 이루는 피그먼트 분산제와의 반응성이 낮아서 품질이 안정적이다. 따라서, 종래와 같이 폴리에틸렌 재질로 제작된 피스톤에 비해 화장품성분의 침투로 인한 팽창(스웰링)이나 기타 트러블현상이 잘 생기지 않게 된다.By the way, the piston 18 is divided into the main body 19 and the rim member 20 are coupled to each other. The main body 19 and the rim member 20 are made of different foreign materials. Preferably, the main body 19 is formed of a material that is more expandable than that of the edge member 20, that is, a swelling characteristic, and the edge member 20 is made of a material having excellent airtightness or lubricity. As the frame member 20, a soft elastic polyethylene resin that has been conventionally used as a piston material is suitable. Preferred materials for the main body 19 are polypropylene (PP) resins, acrylonitrile-styrene (SAN) resins, saturated polyester series PET, PETG, PCTG and the like. These resins have relatively low airtightness or lubricity compared with polyethylene resins, but the advantage is that they do not cause trouble because they do not directly contact the inner wall of the container 11. to be. Therefore, expansion (swelling) or other trouble caused by the penetration of cosmetic components is less likely to occur than the piston made of polyethylene as in the prior art.

바람직하게는, 테두리부재(20)에는 도 2 및 도 3에 도시된 바와같이, 결합홈(24)을 통해 본체(19)의 결합돌기(22)와 결합된다. 그리고, 이 테두리부재(20)는 도 2에서와 같이, 피스톤(18)의 상단부에만 구비될 수도 있고, 도 3과 같이 피스톤(18)의 상단과 하단에 동시에 구비될 수도 있다. 그리고, 도 4에서와 같이, 피스톤의 가장자리 전체가 테두리부재(20)로 구성될 수 있다.Preferably, the frame member 20 is coupled to the engaging projection 22 of the main body 19 through the coupling groove 24, as shown in Figs. And, as shown in Figure 2, the frame member 20 may be provided only at the upper end of the piston 18, as shown in Figure 3 may be provided at the top and bottom of the piston 18 at the same time. And, as shown in Figure 4, the entire edge of the piston may be composed of a frame member (20).

그리고, 이러한 본체(19)와 테두리부재(20)의 연결은 전술한 바와 같이 결합홈(24)과 결합돌기(22)의 끼워맞춤방식 이외에도, 먼저, 본체(19)를 사출성형한 후에, 그 둘레부에 재차 이질재료를 사출성형하는 이른바, 이중사출방식, 기타 적절한 다른 방법에 의해 이질재료를 일체로 성형할 수 있다.And, in addition to the fitting method of the coupling groove 24 and the coupling protrusion 22 as described above, the connection of the main body 19 and the frame member 20, first, after injection molding the main body 19, The dissimilar material can be integrally formed by a so-called double injection method or other appropriate method of injection molding the dissimilar material again on the periphery.

한편, 상기 피스톤(18)이나 테두리부재(20)의 형태는 용기(11)의 단면 형태에 따라 원형이나 타원형, 기타 적절한 형태를 취할 수 있음은 물론이다.On the other hand, the piston 18 or the shape of the rim member 20 may take the form of a circle, oval, or other appropriate forms depending on the cross-sectional shape of the container (11).

이상에서 설명한 바와 같이, 에어리스타입 디스펜서의 피스톤을 그 물성이 다른 두가지 이질재료로 제작하여, 에어리스타입 디스펜서의 피스톤이 원활한 피스톤동작을 수행하면서도 스웰링현상으로 인한 작동불량을 최대한 억제할 수 있다.As described above, the piston of the airless type dispenser is made of two dissimilar materials having different physical properties, so that the piston of the airless type dispenser performs smooth piston operation and can suppress the malfunction caused by the swelling phenomenon to the maximum.
