Abstract

The present invention relates to a foam promoter capable of providing soft and rich foam and a foaming pump including the same. A foam promoter and a foaming pump including the same according to one embodiment of the present invention increase the density of the foam by increasing the friction of fluid particles while the fluid is moving, thereby generating abundant foam, while also preventing the foam from easily collapsing after it is generated, so that the foam can be maintained for a long time.

Description

Foam accelerator and foaming pump containing the same The present invention relates to a foam promoter capable of providing soft and rich foam and a foaming pump including the same. Pump containers are containers that contain fluid contents and discharge the contents through a pumping member, and are widely applied to various containers such as cosmetic containers, detergent containers, and pharmaceutical containers. In addition, a foaming pump dispenser, which is a type of pump container, is currently being provided. The foaming pump dispenser mixes the contents (fluid) stored in the container with air in a gas-liquid mixing chamber and discharges a uniform foamed fluid through a filter screen. It is used for various purposes, such as bath shampoos, hair cosmetics, or various cleaning agents. However, conventional foaming pumps have a problem in that the effect of abundant foam cannot be enjoyed because the foam bubbles collapse rapidly immediately after being generated due to the low density of the foam.
