Abstract:
A method of manufacturing a compartmented container (AC) comprising the steps of:i. forming a plastic pouch (12) open at least at one of its ends (9);ii. forming a metallic aerosol dome top component (1) having an outer depending wall (5) and a dome shaped inner wall (6) ascending to an opening, said dome shaped inner wall (6) including an inner surface thereof coated with a polymeric layer (PL);iii. heat-sealing the at least one open end (9) of the pouch (12) and the aerosol dome top component (1) to each other by means of a plastic-to-plastic bond (B) between the pouch (12) and the polymeric layer (PL) upon the dome shaped inner wall inner surface of the aerosol dome top component (1);iv. inserting the pouch (12) into a tubular container body (AC) such that the aerosol dome top component (1) is adjacent one open end of the container body (AC); andv. securing the aerosol dome top component (1) onto the container body (AC) by means of a seaming operation (DS) between the container body one open end and a terminal peripheral portion (PE) of the aerosol dome top component (1) radially outboard of the plastic-to-plastic bond (B) whereby the latter is not adversely affected during the seaming operation.
