US 10,518,485 B2 · Method for producing plastics containers

Abstract

The invention relates to a method for producing plastics containers from thermoplastics with inserts which, by exploiting the heat of plasticization, are connected during shaping of the plastics container by a material bond and/or interlocking connection to the container wall, wherein the method provides the use of at least one opening on the insert, which opening forms a melt duct or melt inlet and/or melt passage for plasticized or plastic material of the container wall, wherein the method is distinguished in that the opening is monitored as a reference opening by optical and/or sensory means during the production of the connection, wherein the degree of penetration of the opening with thermoplastic from the container wall is used as a measure of the quality of the connection.

A method for producing a plastic container, comprising:

heating a thermoplastic material;
shaping the thermoplastic material into a wall of the container;
providing at least one insert, wherein the at least one insert includes at least opening;
connecting the at least one insert to the wall of the container by at least one of a material bond with the thermoplastic material and an interlocking connection with the thermoplastic material;
monitoring the at least one opening with at least one sensory device during the connecting of the at least one insert to the wall of the container;
determining a degree of penetration of the at least one opening by the thermoplastic material;
and
using the degree of penetration of the at least one opening by the thermoplastic material as a measure of quality of a connection between the thermoplastic material and the at least one insert.
