Device for packaging a product with a manual pump for dispensing individual metered amounts

A device for packaging and dispensing a product comprising:

• a rigid outer container having an open neck and a closed bottom;
• a deformable inner container having a body and an open neck which is more rigid than said body, said inner container being accommodated inside of the outer container with a volume provided therebetween and containing a product to be packaged and dispensed;
• a manual pump which operates without air intake into said inner container to dispense the product in individual metered amounts, said pump having a body which is mounted on said necks of said inner container and said outer container;
• a leaktight means for sealing said manual pump in a leaktight manner with the neck of said inner container on which said pump is mounted;
• a channel which provides external air intake into the volume between said inner container and said outer container at least when said pump is actuated, said channel including (a) at least one air intake passage located outside of said leaktight means and located at least partially in one of said necks of said outer container and said inner container and (b) at least one orifice in said body of said pump located outside of said leaktight means;
• and
• a confining means for preventing any part of the product passing through the body of said deformable inner container and into the volume between said inner container and said outer container from escaping through said air intake passage at least when said pump is not actuated.
