DEVICE FOR DISPENSING STERILE SOLUTION FROM CONTAINER

摘要

A dispenser for dispensing sterile solution which includes a valve means to control the dispensing of the sterile solution from a container. The valve means comprises a solution outlet means, and an air inlet opening having associated therewith a filter membrane to filter the air passing into the container. When dispensing solution force is applied to the container in order to achieve this, and this force causes the solution outlet means to open and prevents access of the solution to the air inlet opening. Now when the force is relieved a partial vacuum is formed in the container which causes the solution outlet means to close and air is drawn into the container via the air inlet opening and through the filter membrane.
