Abstract
A cylindrical bottle which collapses along helical groove, ridge and connecting rings along its sidewall. When inward force is applied along the bottle's vertical axis, the helical groove rings and connecting rings fold under the ridge rings and remain substantially “locked” under the ridge rings, thereby causing the sidewall to collapse and remain collapsed until sufficient outward force is applied. When sufficient outward force is applied along its vertical axis, the bottle extends as the distance between its helical groove rings and ridge rings lengthens. Due to the diamond-shaped cross-section of the connecting rings, in conjunction with the silicone composition of the bottle's body, the collapsing and extension of the bottle occur in sequential segments, creating a unique, playful sound and an amusing worm-like movement.
