Abstract
Non-symmetric and volume reduced preforms and containers stretch blow moulded therefrom by a continuously rotating, preform feed, stretch-blow-moulding machine dedicated to the stretch-blow-moulding of containers from non-symmetric or reduced volume injection moulded preforms; the non-symmetric or reduced volume preforms including an integral handle extending from a first junction point to a second junction point on a body of the preform; the body of the preform and the integral handle constituted from the same material.
Claims16
A continuously rotating, non-symmetric preform feed, stretch-blow-moulding machine dedicated to the stretch-blow-moulding of containers from non-symmetric injection moulded preforms;
- the non-symmetric preforms including an integral handle extending from a hollow body;
- at least a portion of walls of the hollow body varying in thickness;
- the hollow body of the preform and the integral handle constituted from the same material;
- the machine including a preform orientation system to orient the handle of the preform into a known orientation at arrival at a pick off position;
- the known orientation of the preform maintained from the pick off position and rotated into a position in which the handle is oriented for insertion into a continuously rotating stretch blow moulding die.
An injection moulded preform forming a stretch-blow moulded container;
- the preform and the container including an integral handle;
- the preform characterised that at least one element of a body portion of the preform is irregular;
- wherein the at least one irregular element comprises a discontinuity in cross sections of the body of the preform;
- an upper portion of the body below a neck portion of the preform having inner and outer diameters substantially identical to inner and outer diameters of the neck portion;
- a lower portion of the body having reduced inner and outer diameters;
- the upper portion and lower portion interconnected by a short transition section;
- the preform transformed into the container on a continuously rotating stretch-blow moulding machine wherein orientation of the handle is maintained from a known orientation at a pick off position and rotated into a position in which the handle is oriented for insertion into a continuously rotating stretch-blow-moulding die.
