도시된 바와 같이, 화장품 용기에 적용되는 가압식 펌핑장치는 그 구성이 용기본체(10) 상단부에 설치케이스(20)와, 하부 및 측부를 관통시키는 연결통로(31) 가 형성된 압입버튼(30)을 순차적인 형태로 결합시키고, 가압식 펌핑수단(40)을 상기 설치케이스(20)의 설치하되, 상기 압입버튼(30)으로 내용물이 유동되도록 상기 가압식 펌핑수단(40)과 상기 압입버튼(30)의 하부에 개방된 연결통로(31)의 일단을 연결시켜주는 유체유도관(50)으로 이루어져 있다.As shown, the pressurized pumping device applied to the cosmetic container has an installation case 20, the press-fit button 30 is formed on the upper end of the container body 10, the connection passage 31 through which the lower and side portions are formed. Coupled in a sequential form, the pressure pumping means 40 is installed of the installation case 20, the contents of the pressure pumping means 40 and the press-fit button 30 so that the contents flow to the press-fit button 30 Consists of a fluid induction pipe 50 for connecting one end of the connection passage 31 opened in the lower portion.

여기서, 양단이 개방된 관형상을 갖는 종래의 토출구(60)는 상기 압입버튼(30)의 측부에 개방된 연결통로(31)의 타단에 내삽되어 연결된 구조를 갖는다. Here, the conventional discharge port 60 having a tubular shape of which both ends are open has a structure interpolated and connected to the other end of the connection passage 31 opened at the side of the press-fit button 30.

따라서, 상기와 같은 구성을 갖는 화장품 용기에 적용되는 가압식 펌핑장치는 사용자가 외력을 가하여 압입버튼(30)을 누르게 되면, 그 누름작용에 의해 압입버튼(30)의 연결통로(31), 유체유도관(50) 및 가압식 펌핑수단(40) 내에 형성된 공간의 부피는 수축되고, 그 수축된 공간의 부피만큼의 내용물이 종래의 토출구(60)를 통해 토출된다. Therefore, the pressurized pumping device applied to the cosmetic container having the configuration as described above, when the user presses the press-fit button 30 by applying an external force, the connection passage 31 of the press-fit button 30 by the pressing action, the fluid induction The volume of the space formed in the tube 50 and the pressurized pumping means 40 is contracted, and the contents of the contracted space are discharged through the conventional discharge port 60.
