ABSTRACT OF THE DISCLOSURE A yogurt container and cover therefor obtained from a sheet of thermoplastics material, wherein said container com- prises a hollow frustoconical body, radiused to flat edge by means of at least an annular step-like-projection and by means of a side wall portion, and wherein said cover being nestable in the container above said body comprises a peripheral wall and a cen- tral handgrip. The side wall portion is formed of an upper part downwardly frustoconical and of a lower cylindrical part. A plu- rality of recesses are provided inside the container in the region where said cylindrical part and said frustoconical part join together, each recess being formed of a base and of an upwardly tapered wall and being a spacer between stacked empty containers. The elastically yieldable peripheral wall of the cover is upwardly substantially frustoconical and can be radially pressed is and/or outwardly by means of at least an annular channel provided between the said peripheral wall and the hand- grip and by means of the cylindrical part of said wall portion of the container to improve considerably the tightness between the cover and the container and to withstand inwards bending of the side wall of the container. According to another embodiment the side wall portion of the container comprises a back draft part, a projection, a cylindrical part and a downwardly frustoconical part, whilst in another embodiment the peripheral wall of the cover is downwardly frustoconical and in its upper part is pro- vided with a small flange. For an easy removal of the cover the side wall of the handgrip is of a downwardly frustoconical shape and/or is provided with downwardly frustoconical flutes tapering towards the axis of the cover for facilitating axial drafts on the cover and/or for imparting torsional movements to the cover around the axis thereof.
