  • Patent number: 6053375
    Abstract: A non-resealable, snap-fitted closure comprises a closure, a drop ring and a container. The closure has a sleeve with a sleeve snap. The drop ring has an internal snap and an external snap wherein the internal snap engages the sleeve snap of the closure when the closure engages the drop ring. The container has a neck and a neck snap, wherein the neck snap and the internal snap of the drop ring engage when the closure and the drop ring engage the neck. The neck snap of the neck and the internal snap of the drop ring are an order of magnitude stronger than the sleeve snap of the sleeve and the external snap of the drop ring. When the closure is removed from the neck, the drop ring remains attached to the neck and is free to move vertically up and down along the neck, thereby preventing reattachment of the closure to the container.
