Abstract (en)
[origin: US5799863A] PCT No. PCT/FR95/00712 Sec. 371 Date Nov. 29, 1996 Sec. 102(e) Date Nov. 29, 1996 PCT Filed Jun. 1, 1995 PCT Pub. No. WO95/33654 PCT Pub. Date Dec. 14, 1995Cup made from a rectangular sheet folded to form a convex base consisting of two isosceles triangles with a common base. The ends of the common base extend into two areas in the shape of deformable lozenges for folding and unfolding the cup while leaving the base flat. When the cup is unfolded by pressing on the edges to draw them together, the ends abut on the edges of the dihedrals forming the cup sides, thereby locking the cup into an open position.
