Lightweight rod of stuck-together cylindrical beakers which are made of metal with equal sized constant diameter pushed into each other and secured by adhesive layer provided in overlapping wall areas

摘要

The beakers (121) are made of metal such as aluminium and have an equal sized constant diameter. They are pushed into each other by an open end so as to overlap an end having a base (16). An adhesive layer (17) is provided in order to stick between overlapping wall areas of adjoining beakers. The beakers are produced by deep drawing and are pushed into each other by a distance amounting to 2 to 98 percent of the length. Some areas of the rod can be formed by more than two overlapping walls.
