The neck of the containers includes a flange which cooperates with a recessed tubular chamber provided in the base of the containers. The flange is housed in the chamber, such that it is free to move radially, but bears axially against a shoulder in one direction. Bosses are provided on a flared section that extends from the neck and said bosses are received in cavities located in a flared pocket that extends from the above-mentioned chamber. The bosses and cavities form members that provide axial and radial stabilization for the nesting arrangement formed when the flange bears against the shoulder and they include inclined lateral-pressure-bearing ramps used to separate two assembled containers. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The receptacle according to claim 1, wherein the flange is solid and is of a thickness that is significantly thicker than that of the wall of the container delimiting its interior volume. ### Claim 3 (depends on 2) The receptacle according to claim 2, wherein the flange is formed of a ring for receiving a preform from which is moulded the wall of the container by blow-moulding a thermoplastic material. ### Claim 4 (depends on 1) The receptacle as claimed in claim 1, wherein the shoulder is formed by the wall of the container using a plurality of successive inflections of this wall, which provide a bearing seat for the flange extended by a spacer of generally axial extension of separation between the seat and the flared pocket. ### Claim 5 (depends on 1) The receptacle as claimed in claim 1, wherein the containers incorporate means for relative immobilisation between two assembled containers, associating an antagonistic axial bearing engagement of the containers between the flange against the shoulder and the flared section against the flared pocket, and a radial bearing engagement between cooperating axially extended reliefs that respectively the flared section and the flared pocket comprise. ### Claim 6 (depends on 1) The receptacle as claimed in claim 1, wherein the flared section and the flared pocket comprise cooperating members for the radial stabilisation of the nesting between two containers, against a radial freedom of movement of the flange inside the chamber. ### Claim 7 (depends on 1) The receptacle as claimed in claim 1, wherein the flared section and the flared pocket comprise cooperating members for lateral bearing which generate an axial force between two assembled containers, under the effect of a relative rotating force carried out between the assembled containers. ### Claim 8 (depends on 5) The receptacle according to claim 5, wherein the flared section and the flared pocket comprise cooperating members for the radial stabilisation of the nesting between two containers, against a radial freedom of movement of the flange inside the chamber, wherein the flared section and the flared pocket comprise cooperating members for lateral bearing which generate an axial force between two assembled containers, under the effect of a relative rotating force carried out between the assembled containers, and wherein the members for stabilising, the members for lateral bearing and the cooperating reliefs are confounded, by being formed respectively by at least one boss arranged on the flared section of a container which cooperates with a cavity arranged in the flared pocket of a neighbouring container. ### Claim 9 (depends on 8) The receptacle according to claim 8, wherein the contact surfaces between the boss and the cavity are transversally arched and arranged ramps of antagonistic lateral bearing which are axially extended by being inclined in relation to the axis of general extension of the containers. ### Claim 10 (depends on 8) The receptacle according to claim 8, wherein the ramps are inclined in relation to the axis of general extension of the containers by an angle between 30° and 75°. ### Claim 11 (depends on 1) The receptacle as claimed in claim 1, wherein the neck comprises at its free end means of junction that are easily reversible with a removable cap. ### Claim 12 (depends on 11) The receptacle according to claim 11, wherein the flange is formed by a ring arranged at a base of the cap.
