Abstract
A blow-molded plastics bottle having a neck, a side wall and a base, includes an internal spider attached to the side wall of the bottle. The spider and the side wall are formed from biaxially-oriented plastics such that the strength of the bottle is increased and such that the bottle resists the pressures caused by the contents thereof.
Claims8
A blow moulded plastics bottle (10) having a neck (12) formed to receive a bottle closure, a side wall (11) and a base (13), and including an internal spider (16) attached to the side wall (11), said spider extending approximately from the neck to the base and across the inside of the bottle (10), characterised in that the material in the side wall (11) and the spider (16) is bi-axially oriented so that the spider (16) resists tension and acts as an internal reinforcing structure to prevent outward deformation of the side walls.
