A method for manufacturing a container includes injecting a first material into a first mold to form a top portion of a preform. The first material and a second material are injected into the first mold to form a bottom portion of the preform. The preform is disposed in a second mold. The preform is blow molded into a finished container.

A system for forming a container includes an injection station configured to inject a liquid material into a mold to form a preform. The system also includes a forming station including an apparatus for forming a container. The apparatus includes a blow mold configured to receive the preform and inject air into the preform to form the container. The blow mold includes an inner mold surface. The apparatus also includes at least one stretching rod configured to contact the preform in the blow mold and stretch the preform. The apparatus further includes electric heating elements coupled to the blow mold and positioned adjacent the inner mold surface to heat the inner mold surface. The system further includes a removal station configured to release the container from the system.

A unit for bonding the container with the lid, made of plastic, designated especially for pressurised beverages, having a profiled rim of the container opening and a profiled rim of the lid, characterised in that the profiled rim of the opening (2) of the container (1) comprises a flange (3) formed around the said opening (2), extending outwards away from the side wall of the container, where the flange (3) has a top surface (4), side surface (5) and bottom surface (6) bonded to the external side surface of the container (1), and where formed on the top surface (4) around the opening (2) of the container (1) there is a rib (7) protruding above the surface (4), while the profiled rim of the lid (8) comprises a groove (9) formed on the bottom surface (10) of the lid (8) around its bottom edge, the groove (9) accommodating the said rib (7) which supports the lid (8) without touching on the top surface (4) of the flange (3), where there is an energy director (12, 13) formed on the bottom of the groove (9) or the top surface of the rib (7), which focuses ultrasonic energy in the process of ultrasonic welding of the rib (7) and the lid (8).

A thermoplastic pre-container, typically a blow molded piece, is provided to form several hollow bodies. The pre-container is elongated along a central axis and includes a bottom section, an opened section and in-between at least one hollow body section. A plurality of circumferential grooves are provided in a pre-container sidewall, each with a bottom line formed in a virtual plane perpendicular to the axis. The bodies are obtained after cutting the pre-container in a direction transverse to the central axis and severing the end sections. Due to the cutting at several of the circumferential grooves, a top opening and a base opening are respectively obtained for at least two hollow bodies, each opening being delimited by an annular inner rim of a body flange.

A method for manufacturing a food and/or beverage packaging container is provided. The method includes injection molding a preform using a two phase injection system. A first phase of the two phase injection system includes injecting a first material into the preform and a second phase of the two phase injection system includes injecting a second material into the preform. The method further includes disposing the preform in a mold, blow molding the preform into an intermediate article having a length, a diameter and side walls having a wall thickness, and trimming the intermediate article to form a finished container having a wide mouth neck. Systems and finished products are disclosed.

A container including a finish at a first end of the container defining an opening. A base is at a second end of the container that is opposite to the first end. A shoulder extends from the finish. A body defines an internal volume and extends from the shoulder to the base. A single layer material portion of the container extends from the first end to form at least a portion of the finish. A multi-layer material portion of the container extends from the single layer material portion to the second end of the container and across the base. A transition area is spaced apart from the first end where the single layer material portion transitions to the multi-layer material portion.

The container is provided with a one-piece hollow body made of plastic material and a bottom portion. The body is tubular and includes a side wall extending around a longitudinal axis from an annular base to a top provided with a wide top opening. A thin flexible lid covers and seals the top opening. The base is provided with a base flange, of annular shape, that continuously surrounds a wide base opening of the hollow body. A flexible base lid made of foil material is in annular sealing contact with the flange to close the base opening and define all or part of the bottom portion. Such bottom portion and the side wall delimit an interior volume suitable for receiving a product. The body is typically a blow molded piece.

A blow molding device of the invention includes a pair of blow cavity split molds (50A, 50B), a chuck member (80) that chucks a mouth portion (20) and conveys a preform (10A), a blow core mold (70) that includes a tubular portion (71) which surrounds circumferences of the mouth portion and a flange (25) and introduces blow air into the preform, and a pair of projecting members (60A, 60B) which have a halved ring shape and are provided detachably on each upper surface of the pair of blow cavity split molds. Each of the pair of projecting members includes an airtight sealing portion (61) which is in contact with a lower end face of the tubular portion of the blow core mold, and a positioning portion (62) which positions the flange of the preform.

A method for manufacturing a glass with a stem or with a base made of a plastic material, the glass including a receiving portion mounted over a base or over a stem, the method being implemented by a rotary tooling comprising a plurality of workstations and at least one mold wherein the method includes the following steps: a) forming of the receiving portion of the glass on at least one first workstation called injection station; b) overmolding of the stem or of the base over the receiving portion, in order to form a glass with a stem or with a base, the overmolding being carried out on at least one other workstation called overmolding station; c) ejection of the glass thus formed on the overmolding station or on another workstation called ejection station.

A container (1) and a screwable closure (2) comprising a hollow body (11) and a neck finish (10) terminated by a wide-mouth opening (100). Said neck finish comprises a neck support ring (102) and a neck portion (101) extending between the wide-mouth opening (100) and the neck support ring (102). The neck portion (101) comprises an upper portion (1010) and a reinforced lower portion (1011). The inner face (1011 b) of the reinforced lower portion (1011) is transitioning to the inner face (1010b) of the upper portion (1010) along a transition step (1011c) in such a way that said reinforced lower portion (1011) is thicker than the upper portion (1010) at least in a top part of the reinforced lower portion (1011). The neck support ring (102) is below the removable closure (2).
