Abstract
The method for forming a film (p) of flexible and deformable material, by drawing, into an open container intended for packaging a food product, consists in moulding the film in a mould cavity in order to form therein a recess having a surface whose area and perimeter (10, 15, 16, 13) are essentially equal to those of the internal surface (10, 11, 12, 13) of the desired container. That part of the mould cavity corresponding to a join between a side wall and the base of the container has a radius of curvature greater than that of this join. In each corner of the cavity, the surface of the cavity has a protrusion (18) extending into the cavity. During moulding, the film is moulded around these protrusions (18) in order to form folds (pleats) having opposed sides. After having withdrawn the moulded film from the cavity, the opposed sides are opened out in order to obtain the desired container. This method enables a moulded container to be obtained from a plastic film having approximately equal wall thicknesses.
