Shampoo paste container with spray - is sachet with channels which convey liquid to spray jet via swirl chamber

摘要

The shampoo sachet is made of two sections of sheet material assembled together to form a container and and spray for small quantities of liquid. The container has a system of channels (4) through which the liquid is conveyed to a swirl chamber (2) containing a spray jet. A barrier (8) retains the liquid in the chamber (5) before use. On compression, the barrier is ruptured and the liquid passes to the jet. The channels (4) are shaped to accelerate the liquid and discharge it tangentially into the swirl chamber.
