Abstract
An integrally formed injection moulded tubular plastics container body open at one end and closed at the other end. A sleeve (10) of sheet material lies outwardly of the injection moulded plastics (28) of the tubular wall and a layer (20) of sheet material lies inwardly of the injection moulded plastics (30) of the end wall, both sheets (10,20) being secured to the plastics (28,30) during the moulding operation. In producing the container, the sleeve (10) is inserted into the female mould and the other sheet (20) is inserted so as to lie transversely across the mould, partway along the sleeve, and hold the sheet to the mould walls while the male mould member is inserted, carrying the transverse sheet (20) to the end of the mould.
