A preform suitable for subsequent blow-molding into a final-shaped container comprises: a neck portion; a base portion; and a body portion extending between the neck portion and the base portion; the body portion being defined between an inner surface having a circular transverse cross-sectional shape and an outer surface also having a circular transverse cross-sectional shape, the inner and outer surfaces being non-concentric, such that a wall thickness of the body portion varies circumferentially around the preform. A preform handling apparatus for retrieving a preform from a mold comprises a take-off device having a preform carrier and a take-off device alignment mechanism for maintaining the preform carrier in alignment with a contact surface of a body portion of the preform regardless of any offset between a longitudinal axis of a cylindrical outer surface of the body portion and a longitudinal axis of a cylindrical inner surface of the body portion.

A plural preform assembly having nested preforms with an inner preform and an outer preform. The preforms are sealably joined together, defining a volume between the preforms. Propellant is disposed in the volume between the preforms. The preforms are later blow molded to provide a bag in bottle, bottle in bottle or similar container. The propellant charge is already present when blow molded, preventing the need for a later propellant filling step.

A preform for a container has a hollow cylindrical main body having a first thickness, a hollow cylindrical thick portion having a second thickness greater than the first thickness, and a curved end portion. Inner surfaces of the main body, the thick portion, and the end portion form a cavity.

Disclosed is a container perform made from plastic material, including: a body; an open neck that extends from the body from which it is separated by a radially projecting flange; a bottom that closes the body opposite the neck; the body having a concave portion in axial cross section, where: B≤0.9.Math.A 0.5.C≤C′≤0.95.C in which A is the overall diameter of the body, measured below the flange; B is the outer diameter of the bottom, measured at the junction of same with the body; C is the cumulative height of the body and the bottom, measured from the flange; C′ is the height, measured axially, of the concave portion of the body, and the concave portion has, in axial cross-section, on an outer surface, an outer radius of curvature RE such that: 1.5.0≤RE≤10.C

Disclosed herein, amongst other things, is a molded article, such as a preform that is blow moldable to form a container, and a related method of forming and recycling a container. The structure and steps includes injection molding a molded article having tubular body.

The present invention provides a double container capable of suppressing the deterioration of the gas barrier property under high humidity environment. According to the present invention, provided is a double container comprising a container body, wherein the container body has an outer shell and the inner bag, the container body is configured such that the inner bag contracts as content is reduced, and the inner bag comprises an inner layer, a gas barrier layer, and an outer layer, in order from an inside of the container body.

Blow molded articles having a predetermined feature incorporated into the wall provided by variations in the thickness of the wall of the article corresponding to a predetermined pattern etched into the perform from which the article was formed. Also, etched performs for making blow molded articles and methods for making such performs and articles.

A blow moulding machine for blow moulding a container having an integrally formed handle; said container blow moulded from a previously injection moulded preform; said preform comprising a body portion and said integrally formed handle; said machine including a preform loading station at which said preform is oriented by a preform orienting apparatus.
