• the elastic essential annular segments 3a, 3b have essential frustroconical shape and the height of the same are at least the same as the height of respective stiff essential annular segment.
• Fig. 4 the article according to the invention is shown in the shape of a hamper 10.
• the hamper is constructed in the same way as the article/cup in Figs. 1-3, i.e. it has three stiff essential annular segments 20a, 20b, 20c, which in pairs are connected by an elastic flexible essential annular segment 30a, 30b.

• the stiff segments of the article according to the invention are preferably made of a plastic material and the elastic flexible segments are preferably made of an elastic material, but the stiff segments may be made of metal. Both the stiff and the elastic flexible segments may be made of the same material, but with different thickness. For instance, the stiff segment may have a thickness of material of about 2.0 mm and the elastic flexible segment may have a thickness of material of about 0.7 mm.
• the plastic material may be
• polypropylene PP
• ABS acrylonitrile butadiene styrene
• the elastic material may be thermoplastic elastomer (TPE) , thermoplastic polyurethane (TPU) or mixtures of PP and EPDM rubber, so called TPV-material .
• Figs. 5a-c illustrate the preferred angle between a base plane, in the case shown, the bottom of the article and the side wall of a cup, a hamper and a bucket, respectively.
• the angle is different dependent upon the article, and for a cup being about 54° to 82°, preferably about 72° to 80°, and particularly about 76°, for a hamper being about 72° to 86°, preferably 78° to 86°, and particularly about 82°, and for a bucket being about 76° to 88°, preferably about 80 to 88°, and particularly about 84°.
• the height H of the elastic flexible segment should be Dxll (Dxpi) larger/longer than the height h of the stiff segments. This for enabling in the collapsed position of the article as little construction height as possible.

• the distance D is the same in the collapsed and in the non- collapsed/expanded position of the article. Furthermore, the distance D must not be less than the thickness of material of the elastic segment. The distance D must be less than the height H of the elastic segment for enabling the article to stay in the collapsed position .
• the side walls of the article have a cushioning/protecting effect. This is particularly the case when the article is a pail, a bucket or a hamper, which may be used when picking mushrooms or berries, for instance, or for protection of other touch sensitive objects.
