A pre-form assembly to make a container (110) for beverages comprises an external pre-form (12) and an internal pre-form (14), each configured to form respectively an external drum (112) and an internal bag (114) of the container (110). The internal pre-form (14) is associable internally with the external pre¬form (12) so as to define with the external pre-form (12) a hollow space (13), and the internal (14) and external (12) pre-forms comprise respective coupling members (30, 34, 38) in correspondence with respective neck portions (22, 26) suitable to reciprocally position the external pre-form (12) and the internal pre-form (14) along a longitudinal axis (X).

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.

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.

A preform can be made from two different materials that do not bond together by a bi-injection process, using the same mold. First an outer preform can be fashioned first, then an inner preform molded through a center hole in the outer preform, and the preforms connected. Inner/outer preform materials can be different, e.g., PET/polyolefin or polyamide, or the same, e.g., PET/PET. To prevent mutual bonding during molding of the second, a non-stick coating can be sprayed on a surface portion of the first preform prior to molding, the second. Manufacturing order can be either outer/inner, or inner/outer, and the non-stick coating sprayed on the inside/outside of the perform first molded.

A method of manufacturing a pressure vessel that includes heating a preform formed of a thermoplastic polymer, inserting a blow pin assembly that includes a bung portion and a plunger portion into an opening of the heated preform, clamping the heated preform between the bung portion and sections of a blow mold, extending the plunger portion into an interior of the heated preform to stretch the heated preform in the blow mold, and blowing air into the stretched preform under pressure to form the pressure vessel such that: (a) the pressure vessel includes a tank having a neck portion, a cylindrical body portion having a diameter of at least about 200 mm, and a bottom portion, (b) at least the thermoplastic polymer in the cylindrical body portion is biaxially oriented, and (c) threads are formed in the neck portion. Also a pressure vessel formed in accordance with the method.

A plural preform assembly including an outer preform and an inner preform. The outer preform includes an outer preform open end, an outer preform closed end longitudinally opposed thereto, and an outer preform sidewall joining the outer preform open end and the outer preform closed end. The inner preform may be disposed in the outer preform. The inner preform includes an inner preform open end, an inner preform closed end longitudinally opposed thereto, and an inner preform sidewall joining the inner preform open end and the inner preform closed end. The inner preform has an inner preform intrinsic viscosity and the outer preform has an outer preform intrinsic viscosity. The inner preform intrinsic viscosity and the outer preform intrinsic viscosity are different. The plural preform assembly may be blow molded into an article.

A container sealing machine comprising: a rotary turret having a plurality of sealing heads arranged to rotate about an axis of the rotary turret, each sealing head comprising: an inductive heater arranged to inductively heat a foil closure of a container, and a sealing surface arranged to exert pressure on the closure, and a plurality of gripper assemblies arranged to rotate about the axis of the rotary turret, each gripper assembly being arranged for engaging a neck of a container; a bottle and a closure for use in such a machine; and a machine and method for manufacturing such a closure.

A plural preform assembly having nested preforms. The preforms are held together by an interference fit. The interference fit is provided by the friction between the preforms which occurs when the inner preform is inserted into the outer preform. At least one preform may have ribs extending radially towards the other preform. The ribs provided concentricity and interference to hold the preforms together during subsequent operations. The preforms may later be blow molded to provide a bag in bottle or similar container.

The invention relates to a container comprising a container wall that partly surrounds a container interior, wherein the container wall a) has a container opening; b) comprises a container layer comprising i) a multitude of particles, and ii) no fold and no crease;  and c) comprises a first polymer layer that at least partly superimposes the container layer;
wherein the container interior a. has a maximum diameter in a plane perpendicular to a height of the container interior, and b. has a diameter less than the maximum diameter of the container interior at least in sections in the direction from the plane to the container opening.

The invention further relates to a method of superimposing a container precursor with a polymer composition; a container obtainable by that method; an apparatus for superimposing a container precursor with a polymer composition; a method of filling and closing one of the aforementioned containers and the closed container obtainable thereby; and uses of a filling machine, of one of the aforementioned containers, of a polymer composition, and of a powder coating system.
