<p>The beaker designed to hold yoghurt, ice drinks, and is enclosed for distribution purposes. It is constructed from two side walls which are quadratic, made of stable and foldable material. The side walls are joinable to each other along left and right side edges. Its lower edges are joined by a foldable base, the V-shaped left and right edges of which are attached to the corresponding side wall edges. This base (10) is made of tough cardboard lined with plastics and has fold lines scored (16, 17, 18) into it. Likewise the insides of the beaker are of plastic-lined material, and the upper side edges (13) are widened. A metal strip reinforces the beaker side walls.</p> |
