전산유체해석을 이용한 듀얼 펌프캡 용기의 토출 비율 연구

Abstract

Pump-cap is a device for discharging the contents stored inside a container to the outside of the container bya simple operation by a certain amount. In particular, in recent years, as the number of cosmetic products made offunctional materials has rapidly increased, the development of convenient containers for functional materials is beingactively conducted. Among these, there are a growing number of products that show their efficacy only by mixing twocomponents, so the development of a dual pump cap container is necessary. However, the conventional dual pump capcontainer has a problem in that it is difficult to implement a quantitative discharge as solutions having different viscositiesare used. Therefore, in this study, a discharge port of a dual pump cap that can apply an optimal ratio was designed byanalyzing the discharge amount of two components with different viscosities through computational fluid dynamics. Sincethe discharge amount is affected by the size of the discharge port, the higher the viscosity of the solution, the larger thedischarge port should be set. Conversely, the lower the viscosity, the smaller the discharge port should be. Through this,it is possible to dispense a fixed amount of a heterogeneous solution by one pumping, and it is determined that the user'sconvenience will increase.
