- (i) providing a tubular container body having an opening set-off by a curl,
- (ii) providing a laminated component for the container from a pre-laminated sheet comprising a metal substrate layer having a layer of polymeric material bonded over the whole of at least one side of the substrate layer,
- (iii) forming the laminated component into an aerosol valve cup having a central portion and an annular channel,
- (iv) positioning the annular channel of the aerosol valve cup upon the curl of the aerosol container with the polymeric material sandwiched therebetween, and
- (v) urging the annular channel and curl by mechanical deformation into a crimped mechanical connection, while compressing the polymeric material to form an air/gas-tight seal,
- steps (ii) through (v) being performed without any sealing material (other than said polymeric material) present by virtue of step (ii) being or having been introduced, without adding heat, and without any bonding between the annular channel and curl.
