Abstract

It is proposed a process for fastening an accessory to the interior of a blow-molded tank, the tank having a plastic wall produced from a parison, the accessory comprising a body having at least one attaching portion projecting radially from the body. The process comprises the steps of: a) introducing the accessory and the parison in a molten state into a mould so that the accessory is surrounded by the parison, the mould comprising cavities, at least one cavity being equipped with at least one movable insert configured to fold locally some of the molten parison on the attaching portion; b) contacting the parison with the attaching portion; c) moving forward the insert and folding locally some of the molten parison on the attaching portion; d) closing the mould by moving the mould cavities to a final closing position and inflating the parison to form the blow-molded tank; e) moving backwards the insert; and f) opening the mould.
