Multilayered container, die for multilayered container, and method for producing multilayered container

The present invention relates to a mold for a multi-layer container. The mold includes a cold-half portion containing a cavity, and a hot-half portion containing a first resin flow path for connecting an interior of a first injection cylinder to the cavity, a second resin flow path for connecting an interior of a second injection cylinder to the cavity, and a junction portion of the first resin flow path and the second resin flow path. The junction portion in the hot-half portion is positioned upstream of a gate portion opened to the cavity included in the cold-half portion, the second resin flow path contains an inhibitor for partially inhibiting a resin flow.

Preform and container comprising reinforcing elements

The present invention relates to a plastic preform (200) for a container (300) comprising at least one elongate reinforcing element (210), and obtained by injection-molding. The present invention further relates to a container (300) blow-molded from such a preform (200), and comprising at least one reinforcing element (320), and having a continuous and smooth outer surface (310b).

Process and machinery for integration of discrete parts into composite containers

A process of manual, semi-automatic and fully-automated integration of discrete components into a container that results in fast, reliable, cost-effective, and scalable production of composite containers is disclosed. The process can be embodied in manufacturing equipment that has a series of stations and may be called an assembly device. The equipment can produce containers, tubs, canisters, cartridges, etc. which are easily separated into different bio-degradable or compostable parts. Other container types are possible and are contemplated.

20250135706 · 2025-05-01 ·

A method for manufacturing a bottle, using a preform (1) comprising an open neck portion (2) at a first end (12), a closed base portion (3) at a second end (13), and a body portion (4) extending along a longitudinal axis (A1) between the neck portion (2) and the base portion (3), said preform (1) being made in PHA. The method for manufacturing comprises the following steps:heating the preform (1); andperforming stretch blow molding of the preform (1). The preform (1) has a wall thickness which varies progressively between the body portion (4) and the neck portion (2).

Device and method for producing resin container

A manufacturing apparatus for manufacturing a resin container, the manufacturing apparatus includes an injection molding part, a temperature adjustment part, a blow molding part, a take-out part, and a rotation plate. The temperature adjustment part includes a first temperature adjustment mold into which the preform is inserted, the first temperature adjustment mold being configured to cool the preform from an outer surface of the preform, a second temperature adjustment mold into which the preform is inserted, the second temperature adjustment mold being configured to cool the preform from an inner surface of the preform, and wherein, in the temperature adjustment part, the preform is cooled so that at least the outer surface temperature of the preform is lowered within a temperature range from 10 C. to 50 C. as compared to the outer surface temperature of the preform when the preform is carried into the temperature adjustment part.
