| 摘要 |
The invention concerns a device designed to dispense fluids from a container, air flowing back into the container (1) to equalize the pressure when fluid is dispensed. The dispenser has, located in the region of the air inlet, sterilization or germ-reduction means and, separate from these, disposed along at least part of the fluid outlet, fluid-sterilization or germ-reduction means. This makes it possible for the dispenser to be fitted to existing conventional containers and refill systems and to protect the fluid in the container inexpensively and effectively from contamination, thus making preservatives unnecessary. The dispenser can be in the form of a pump (2) or it can be designed to be fitted to a squeeze bottle (31). |
