<p>#CMT# #/CMT# The method involves deforming a wall of a container (1) i.e. bottle, in a flexible and elastic manner and retaining its initial shape, where the container is provided with an elastic and flexible ring (2) that is made of rubber. A pressure (P1) is exerted on the deformed container wall by a user, to remove a part of a pasty or fluid product e.g. skin care cream, from an elastic and flexible pocket. The pressure is released to authorize an entry of ambient air in the container and prevents the air in the pocket while prohibiting the re-entering of the product in the pocket. #CMT# : #/CMT# An independent claim is also included for a fluid or pasty product preserving and dispensing device comprising a plastic washer, a polyvinyl chloride plate and a plastic envelope. #CMT#USE : #/CMT# Method for preserving and dispensing a pasty or fluid product e.g. cosmetic product such as perfume and skin care cream, pharmaceutical product such as therapeutic gel, and food product such as tomato sauce and mustard, that is packed in an elastic and flexible plastic pocket contained in a container i.e. bottle (claimed). #CMT#ADVANTAGE : #/CMT# The method permits to preserve and dispense the product in a fractionated, intermittent and efficient manner. The method permits to ensure a robust refillable pasty or fluid product preserving and dispensing device. The method permits the product preserving and dispensing device to reduce quantity of refuse rejected in an environment or processed by recycling machine, thus ensuring inexpensive and ecological device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a fluid or pasty product preserving and dispensing device. P1 : Pressure 1 : Container 2 : Elastic and flexible ring 4 : Neck 5 : Elastic and flexible film.</p> |
