摘要

A DEVICE FOR DISPENSING, BY PUMP, FLUID SUBSTANCES CONTAINED IN WATERPROOF CONDITIONS IN A DEFORMABLE PURSE COVERED IN A RIGID CONTAINER. The present invention relates to a device for dispensing, by means of a manually operable pump, fluid substances contained in a deformable pouch housed in a rigid container. The bag has a nozzle with a designed flange into which the pump fits and engages, causing the bag to be removed from the container when the pump is separated from the container after the bag has been emptied.
