Abstract
A container of a fluid including a collar having a passage and a pair of laminated film sheets heat-welded along perimetral welding lines so as to form a bag, the pair of sheets also being heat-welded to the collar so that the passage in the collar provides access to interior of the bag; the outer surface of the collar, in a zone in which the collar is welded to the pair of sheets has, seen in section, an oblong shape with two tapered ends aligned along at least one axis along which the pair of sheets are welded.
Claims11
A container of a fluid, comprising:
- a collar having a passage and
- a pair of laminated film sheets thermally bonded along perimetral welding lines so as to form a bag, the pair of laminated film sheets being also thermally welded to an outer surface of the collar at a welding zone so that the passage of the collar defines an access inside the bag;
- wherein the outer surface of the collar, at the welding zone includes, in section, an oblong conformation with two tapered ends aligned along at least one welding axis where the pair of sheets are welded together;
- wherein the collar includes at least a pair of orientation surfaces to align the collar prior to an automatic welding of the sheets to the collar;
- wherein an end of the collar further comprises a crown having a plurality of parallel torsional coupling teeth for fixing an element of a pump to at least the collar;
- and
- wherein the pair of orientation surfaces are defines by parallel bushes that interrupt the torsional coupling teeth of the crown near said end of the collar, wherein the positioning of a plane containing the pair of orientation surfaces defined by parallel bushes is fixed with respect to the welding plane to be perpendicular to the welding plane.
