A method of sealing a peelable lid () to a flange () provided within a metal can body () which involves inserting an induction coil () into the can body to primarily heat the sealing surface () of the flange, while keeping the exterior wall of the can relatively cool to avoid tin reflow and decoration degradation of the exterior wall. The induction coil is subsequently removed from the can body and a peelable lid applied to the flange, whereby residual heat in the flange aids the sealing of the lid to the flange, e.g. by allowing activation of a bonding material.

The invention provides an aerosol container having an outer container body () with a plastic liner or bag () arranged therein, into which both product and propellant are filled, characterized in that the plastic liner or bag () has a multi-layer construction. The liner or bag () comprises a layer that is resistant to the product and a layer that prevents diffusion of the propellant out of the liner or bag (). Further layers may also be incorporated to provide additional properties as required, for example an oxygen barrier, scavenging etc. Furthermore, one or more tie-layers, such as adhesive for example, may be provided to hold the separate layers together.

Apparatus for spin-welding comprises a spin welding machine having a spin welding head, a ram assembly, and a feed mechanism; the ram assembly is driven from a shaft and the feed mechanism comprises a rotating turret mounted on a shaft which is driven from the shaft via a Geneva mechanism. The spin welding head is driven by a low inertia DC servo motor operated by a programmable logic controller and timed from a switch unit driven off the shaft.
