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.

摘要

The invention relates to a modular receptacle formed by a plurality of axially-nestable necked containers (1). The neck (3) of the containers (1) comprises a flange (11) which cooperates with a recessed tubular chamber (9) provided in the base (2) of the containers (1). The flange (11) is housed in the chamber (9), such that it is free to move radially, but bears axially against a shoulder (12) in one direction. Bosses (17) are provided on a flared section (4) that extends from the neck (3) and said bosses are received in cavities (16) located in a flared pocket (10) that extends from the above-mentioned chamber (9). The bosses (17) and cavities (16) form members that provide axial and radial stabilisation for the nesting arrangement formed when the flange (11) bears against the shoulder (12) and they include inclined lateral-pressure-bearing ramps (18) used to separate two assembled containers (1).
