Bottle with special top for use in the medical field

Abstract

A closure top is especially suited for use with a bottle for medical use, particularly for enteral feeding. The closure top screws onto the bottle. The bottle contents are accessible to a feeding tube by means of a passage through the closure top. The closure top may be provided with a freshness seal which is penetrated by insertion through the passage of the feeding tube or a cannula attached to the feeding tube. The top may have a pressure-relief opening. A semi-permeable membrane may be fitted in the opening.
