The invention concerns an apparatus (10) for simultaneously blowing and filling a plastic container from a preform, the apparatus comprising: a mold (14) for enclosing a preform, so as to leave access to the mouth of the preform, stretching means (42) for stretching the preform within the mold, an injection head (16) for injecting a liquid through the mouth so as to cause expansion of the preform within the mold, thereby obtaining a blown and filled container (12) that comprises a dispensing opening (22), characterized in that the apparatus further comprises a capping head (18) for fixing a cap (40) on the dispensing opening of said blown and filled container, the capping head being permanently arranged between the injection head (16) and the mold (14).

Method for forming containers from preforms carried by successive moulds
12226945 · 2025-02-18 · ·

A method for forming containers from preforms. The method includes loading successive preforms into successive molds at a mold loading station, each mold having a mold cavity in the shape of the containers to be produced. The containers being formed in a forming station by injecting a gaseous or liquid fluid into the preform in order to expand the preform and acquires the shape of the container defined by the mold cavity. The steps performed at the mold loading station and the forming station are distinct from each other, and a transferring step occurs at a transferring station arranged between the mold loading station and the forming station where successive molds containing the preforms are transferred from the mold loading station to the forming station.

ROTARY MACHINE COMPRISING FIRST STATIONS AND SECOND STATIONS ROTATING AROUND A SINGLE MAIN AXIS

A rotary machine includes a main axis, a plurality of first stations and a plurality of second stations. Each first station rotates around the main axis and applies a first process to a container. Each second station rotates around the main axis and applies a second process to a processed container. The machine also includes an internal exit position, at which each first station is located once the first station has completed the first process and that is arranged to release the processed container. At an internal entry position, each second station is arranged to receive the released processed container. At least one transfer arm is adapted to seize a processed container and move the processed container between a first station located at the internal exit position and a second station located at the internal entry position.

CONTAINER AND PACKAGING SYSTEM

A method for manufacturing packaging comprises the steps of: temperature conditioning one or more selected portions of at least one preform; and blowing and/or stretching the at least one temperature conditioned preform into a blow mold to form a container including an offset neck finish. Containers, packaging systems and packaging products are disclosed.

Co-extrusion blow molding apparatus and method, and sealed empty devices
09573741 · 2017-02-21 ·

A device comprising a body including a first polymer and a closure including a second polymer that is substantially not bondable to the first polymer and has a relatively higher shrinkage rate than the first polymer, wherein at least a portion of the closure overlaps at least a portion of the body, forming a hermetic seal therebetween and defining a sealed, empty, sterile container.

Lightweight preform having a decreased weight support ring
09533788 · 2017-01-03 ·

A lightweight polyester preform is disclosed for the production of light weight polyester containers by blow molding. The preforms and the resulting blown containers have threads on an exterior surface adjacent an upper end. Adjacent to and located below the threads is a support ring. The support ring is used in handling and conveying a preform from injection molding to a blow mold and in blow molding the container from the preform. It also is used in handling and conveying the preform from storage to the blow mold. To lightweight the preform, and subsequent container, the support ring is designed to have a minimum weight, but a sufficient strength for the handling of the preform in the production of the blow molded container. The support ring is reduced in weight by about 10% to about 70% from a conventional preform support ring.

Aseptic filling method and aseptic filling machine

A preform is heated, the heated preform is sealed in a sealing apparatus including a neck portion mold, a trunk portion mold and a bottom portion mold at a predetermined temperature range, and the heated preform sealed in the molds is blow-molded into a bottle. Any molded bottle is removed if the mold surface temperature of the neck portion mold, the trunk portion mold and the bottom portion mold are outside of the predetermined temperature range. A sterilizer is blasted to any molded bottle not removed when the mold surface temperature of all of the molds is in the predetermined temperature range.

Apparatus and Method for the Follow-Up Treatment of Container Products

Disclosed is an apparatus for the follow-up treatment, in particular cooling, of container products, which are produced by means of a blow-moulding, filling and closing process, and which can be fed to a follow-up treatment zone, which has an influencing effect, in particular a cooling effect, on the respective container product. The container products enter the follow-up treatment zone singly separate from one another or together in individual groups separate from one another comprising multiple container products. The follow up treatment zone is provided with at least one control means, acting on the container products and determining the time for which they stay in the follow-up treatment zone.

CONTAINER TREATMENT SYSTEM COMPRISING A PREFORM MANUFACTURING MACHINE, A BLOW MOLDING MACHINE AND AT LEAST ONE HEAT RECOVERY DEVICE
20260034718 · 2026-02-05 ·

A container treatment system includes a manufacturing machine for preforms, a blow molding machine, and at least one heat recovery device. A first process medium can be supplied from the manufacturing machine and/or the blow molding machine to a first heat recovery device. Heat can be exchanged between the first process medium and a second process medium of the container treatment system using the first heat recovery device.

Apparatus and process for producing moulded, filled and sealed receptacle products made of plastics material

Apparatus for producing molded, filled and sealed receptacle products made of plastics material, comprisinga hose head (32) for dispensing at least one hose extruded using an extrusion means, a separating means (12) for separating a preform from the hose, a main mold (24) for accommodating at least one preform in the context of molding thereof, a transfer means (14) for transferring the preform from the hose head (32) to a filling means (16) for filling via an opening of the preform, anda supplying means (20) for a sterilizing fluid which allows for flow around at least one filling needle (22) of the filling means (16), characterized in that a further supplying means (30) for sterilizing fluid which at least partially protects at least the opening of the preform in the region below the hose head (32) from contamination is present.
