Abstract
A closure including an upper wall (25) defining an opening (36) and a cylindrical snap on pipe (30) depending from the upper wall. The pipe includes threads (34) designed to mate with external threads on a neck of the bottle. The threads on the pipe and threads on the neck of the bottle pass over each other when the closure is snapped onto the bottle during manufacture. The pipe includes a resistance recess (42) and a guidance recess (70). The resistance recess and the guidance recess accommodate a forcing element (50) on a shoulder (80) of the bottle and permit unscrewing of the closure. The walls (44, 46) of the resistance recess are preferably symmetrical.
Claims19
A closure (22) comprising
- a. an upper wall (25) defining an opening (36);
- b. a cylindrical snap-on pipe (30) depending from the upper wall and extending axially to a bottom end,
- c. the cylindrical snap-on pipe (30) including at least one resistance recess (42) at the bottom end (43) thereof;
- d. the cylindrical snap-on pipe (30) further including at least one thread (34);
- e. the cylindrical snap-on pipe defining opposing first and second walls of the resistance recess;
- and
- f. the bottom end of the cylindrical snap-on pipe being shaped to include a guidance recess (70) consistent with lowering the cylindrical snap-on pipe thread (34) relative to a bottle neck, the closure being configured such that the guidance recess (70) includes a first guidance recess wall (72) with an upward gradient and a second guidance recess wall (74) having a downward gradient whereby in a closure opening direction of rotation the first guidance recess wall (72) permits the cylindrical snap-on pipe (30) axially to be lowered toward the bottle neck having a forcing element and the second guidance recess wall (74) being consistent with the closure cylindrical snap-on pipe being raised relative to the bottle, and the thread (34) maintaining its axial position relative to a thread on a bottle neck to which the closure is being applied when the forcing element contacts one of said resistance recess walls at least until the forcing element reaches a position beneath the second guidance recess wall (74), and wherein the first and second resistance recess walls have gradients, and wherein the gradients of the first and second resistance recess walls are essentially the same at any point lying at the same axial height.
