Abstract

The bottle is made of thin-walled plastic by the lead blow process, the bottom (3) part is pre-formed with an inward protrusion (13), which in a nearly V-shaped cross section, which determines The crease (8) at the bottom, inside the long protrusion, the crease (8) converge smoothly, the hoof around the fold (15, 15 a, 15 b) that extends along the length of the bottle, the inner crease (8) and the crease along Long in the same plane, this plane crosses the seam (9) from the bottle lead. In a two lead mold, the cut shape of the bottle can be a circle, rectangle, canvas or hexagon, and it is the same piece as a spout. Which should protrude with a smaller diameter from the section This is the top of the bottle. So that in folding the bottle Along the seams And expel all air from the inside, the bottle can then be pressed and reduced to a smaller size after the air protection spout is closed.
