Document Type and Number:
WIPO Patent Application WO2006060350
Kind Code:
A3
Abstract:
The present invention relates to a method of reforming the end portion and sealing surface of a blow molded plastic container neck finish. The method includes the steps of directing energy from a non-contact heater (18) onto an annular end portion of a container neck finish (12) so as to heat the end portion to its softening temperature while leaving the remainder of the neck finish relatively unheated, and then engaging the annular end portion with an unheated forming tool (24) so as to reform and cool the end sealing surface of the neck finish (12). Plastic containers, as well as apparatuses for reforming a blow molded plastic container, are also disclosed.
