Container of a bag-in-container type, wherein a neck region of the container is provided with at least one opening extending substantially radially there through, into a space between the outer container and an inner container adjacent thereto, wherein the neck region is provided with coupling elements, preferably at opposite sides of the at least one opening, seen in circumferential direction, for coupling of a connecting device to the container for introducing a pressure fluid through the at least one opening into a space between the inner and outer container.

A method for manufacturing a composite product, including: 1) preparing a composite powder including 10-50 v. % of a polymer adhesive and 50-90 v. % of a chopped fiber; 2) shaping the composite powder by using a selective laser sintering technology to yield a preform including pores; 3) preparing a liquid thermosetting resin precursor, immersing the preform into the liquid thermosetting resin precursor, allowing a liquid thermosetting resin of the liquid thermosetting resin precursor to infiltrate into the pores of the preform, and exposing the upper end of the preform out of the liquid surface of the liquid thermosetting resin precursor to discharge gas out of the pores of the preform; 4) collecting the preform from the liquid thermosetting resin precursor and curing the preform; and 5) polishing the preform obtained in 4) to yield a composite product.

A preform is biaxially stretch blow molded into a container by using a liquid as a pressurizing medium. The preform is formed in a bottomed tubular shape including a mouth, a trunk, and a bottom by extrusion blow molding. The preform includes bottom parting lines, which are formed in the bottom due to the extrusion blow molding, and the bottom parting lines are configured to extend to the outer side from the axis of the bottom to divide the bottom into at least three parts in the circumferential direction. Further, a container is formed by biaxially stretch blow molding the preform by using the liquid as the pressurizing medium.

An innovative neck (301) configuration is suggested in order to reduce the weight of a large container for beverage dispenser. The neck (301) comprises a neck finish (303) which extends in length (Ltot) starting from the wide mouth (302) of the container to an annular support ring (305) and a smooth surface cylindrical portion (306) which joins the annular support ring (305) to the body (309) of the container. For functional reasons, the total length (Ltot) of the innovative neck (301) remains the same as the usual traditional necks for this type of container, but due to the short length (Ltot) of the neck finish (303) and said cylindrical portion (306), the weight is reduced.
