SYSTEM FOR ATTACHING TWO TUBULAR MEMBERS AND CONTAINER FOR LIQUIDS EQUIPPED WITH SAID ATTACHMENT SYSTEM

摘要

The present invention relates to an attachment system for attaching together two tubular members comprising two tubular members, rotational attachment members and longitudinal attachment members. The rotational attachment members comprise a plurality of attachment elements which are disposed in angularly spaced relationship along the first tubular member to define a plurality of seats between two successive attachment elements and a plurality of reference elements disposed in angularly spaced relationship along the second tubular member and at least partially accommodated in respective seats. The longitudinal attachment members comprise a plurality of stop surfaces disposed in angularly spaced relationship along the first tubular member and a plurality of abutment elements formed on the second tubular member, each abutment element extending in the longitudinal direction and cooperating with a respective stop surface. The invention also relates to a liquid container having said attachment system.

1. An attachment system for attaching two tubular members, comprising:
a first tubular member extending along a longitudinal axis, a second tubular member extending along said longitudinal axis, and attached to said first tubular member, rotational attachment members for rotatably attaching said first tubular member to said second tubular member, longitudinal attachment members for attaching said first tubular member to said second tubular member in said longitudinal axis,wherein:
said rotational attachment members comprise:
a plurality of attachment elements formed on said first tubular member and arranged in angularly spaced relationship along said first tubular member to define a plurality of seats between two successive attachment elements, each seat being angularly delimited at its opposite sides by two successive attachment elements,a plurality of reference elements formed on said second tubular member, and arranged in angularly spaced relationship along said second tubular member and at least partially housed in respective seats of the attachment elements, each reference element cooperating with the two successive attachment elements defining the seat in which said reference element is at least partially housed, for rotatably attaching said first tubular member to said second tubular member, said longitudinal attachment members comprise:
a plurality of stop surfaces formed on said first tubular member and arranged in angularly spaced relationship along said first tubular member,a plurality of abutment elements formed on said second tubular member, each abutment element extending along the longitudinal axis and cooperating with a respective stop surface for longitudinally attaching said first tubular member and said second tubular member, each abutment element being defined by a tab attached to the second tubular member at a base portion thereof, said tab radially extending from the base portion to an end portion, at least part of the tab being elastically deformable along an axis transverse to the longitudinal axis.
