20230311402 · 2023-10-05 ·

A method for heating a preform (1) comprising a body portion (4) extending along a longitudinal axis (A1). The method comprises the following steps:—introducing the preform (1) into a heating apparatus (5) comprising an array of infrared emitters (50) arranged in multiple columns (Cj) and rows (Ri); —setting power levels of the infrared emitters (50) so as to divide said array into subsets of columns (SCn); and—heating the preform while translating it in a direction parallel to the rows (Ri), and simultaneously rotating it around its longitudinal axis, the rotation and translation speeds, and the power levels of the infrared emitters (50) being set so that the power levels of the subsets of columns (SCn) facing zones (42) of the body portion extending longitudinally are different from the power levels of the subsets of columns facing the rest of the body portion, said zones extending relative to one another in a polygonal array.

Method for heating a preform (1) comprising: introducing the preform (1) into a heating apparatus (5) comprising an array of infrared emitters (50) arranged in multiple columns (Cj) and multiple rows (Ri), orienting angularly the preform at an input angular position by rotating the preform around the longitudinal axis; setting power levels of the infrared emitters (50) so as to divide the array of infrared emitters (50) into subsets of columns (SCn), each subset of columns (SCn) generating heat at a different power level from an adjacent subset of columns (SCn); and heating the preform (1) with the array of infrared emitters (50) while translating the preform (1) in a direction parallel to the rows (Ri) of the array at a translation speed, and simultaneously rotating said preform (1) around its longitudinal axis (A1) in front of said infrared emitters (50) at a rotation speed.

PREFORM LAYERED BODY AND LAYERED CONTAINER

The disclosure provides a preform layered body and a layered container produced by biaxial stretch-blow forming of the layered body. In this preform layered body, an RFID tag has been inserted between an inner-layer-use mouth part and an outer-layer-use mouth part that are to remain unaltered, with no biaxial stretch-blow forming performed thereon, as a container mouth part for a layered container. Since the container mouth part does not become exposed to the high temperature and high pressure for stretch-blow forming purposes, abuses to the RFID tag, such as damage, breakage, and deformation, which arise from the heating, pressurization, and stretching during the stretch-blow forming, can be avoided reliably. In addition, labor-saving and counterfeit prevention effect can be anticipated by causing the RFID tag to hold product information.

CONTAINER PREFORM
20220288834 · 2022-09-15 ·

A preform configured to be blow-molded into a plastic bottle includes a neck section defining an opening, the neck section including a threaded portion configured to engage a closure, and a neck ring, a transition section having a first end positioned adjacent to the neck ring and a second end opposite the first end, a cylindrical body section extending from the second end of the transition section to a base, and a longitudinal axis extending from the opening through the base. The neck section, transition section, and the body section define a hollow channel positioned between the opening and the base. The transition section defines a tapered sidewall relative to the longitudinal axis, the tapered sidewall decreases a cross-sectional diameter of the hollow channel. The tapered sidewall of the transition section contains 20% to 30% of a total weight of the preform.

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.

FREE BLOW BOTTLE DESIGN

An apparatus and method for simultaneously forming and filling a plastic container without the use of a mold forming a mold cavity (116, 16) is provided. A pressure source (120, 20) includes an inlet (146, 150, 46, 50) and a piston-like device (140, 40). The piston-like device (140, 40) is moveable in a first direction wherein liquid is drawn into the pressure source (120, 20) through the inlet (146, 150, 46, 50) and in a second direction wherein the liquid is urged toward the preform (112, 12). A blow nozzle (122, 22) may be adapted to receive the liquid from the pressure source (120, 20) and transfer the liquid at high pressure (P2) into the preform (112, 12) thereby urging the preform (112, 12) to freely expand until an unopened end thereof contacts a platen (118). The platen (118) forms a bottom in a resultant container. The liquid remains within the container as an end product.
