摘要

#CMT# #/CMT# The container, having at least one deformable wall for expelling a fluid product through a nozzle (4), incorporates a filter block (6) made from one or more layers of a filter material welded together by their edges. The filter block is ring-shaped, supple and elastic, and has a flexible washer (11) at its inner end that acts as a valve. It is inserted with a force fit round the container outlet (7) so that air entering the container to replace the expelled product has to pass through it #CMT#USE : #/CMT# Containing and dispensing a fluid, e.g. food or cosmetic, product. #CMT#ADVANTAGE : #/CMT# The expelled product is replaced by filtered air, reducing contamination of the product remaining in the container. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-section of the container's outlet end in side view. 3 : Container neck 4 : Nozzle 6 : Filter block 7 : Container outlet 11 : Flexible washer.
