Modular receptacle formed by a plurality of axially-nestable containers, and method for producing such containers by means of the blow-moulding of a preform

A modular receptacle comprising:

• a plurality of necked containers that are successively axially nestable with each other with placing in cooperation between their base and their neck extended by a flared section,
• the containers comprising members for axial nesting with a neighbouring container, of which at least one is arranged as a flange arranged around the neck of a container and of which at least one other is arranged as a recess for receiving the flange,
• said recess comprising a cavity open to the exterior which is arranged in the base of the containers and which comprises a blind tubular space for receiving a neck extended by a flared pocket for receiving the flared section extending from this neck, characterised in that
• wherein the recess is formed by the tubular space which is arranged as an undercut in the base of the container, said tubular space defining a chamber for receiving the flange with radial freedom and bearing axially in one direction against a shoulder formed in the base of the chamber opposite its blind surface.
