Abstract

A pref. paper or cardboard container blank comprises a pref. circular central portion (forming the container base) and two side portions which are attached to diametrically opposite sides of the central portion, each side portion being connected to the central portion by two spaced connecting strips between which a slit is provided. The side portions are folded over approx. perpendicularly to the plane of the central portion and then bent into an arc such that adjacent end edges of the side portions touch each other to produce a pref. frusto -conical side wall of the container. The blank is then inserted into a mould into which moulding material is introduced. The moulding material (1) joins the adjacent end edges of the side portions (2) pref. enters the slits and forms an inner fillet to maintain the container side wall and bottom wall in the correct relationship; and (3) pref. forms a skirt around the bottom wall on which the container can stand. The slit may be accurate or straight and prevents deformation of the container side wall or bottom wall, thereby producing a better quality container.
