Abstract: A closure for a container includes a cap connected to a retaining ring. The cap includes a cover and a skirt. A plurality of concentric threads are disposed on an inside surface of the skirt. The plurality of threads includes at least a first thread at a first level and a second thread at a second level. The first thread is comprised of at least a first thread segment separated from a second thread segment by a first space. The second thread is comprised of at least a third thread segment separated from a fourth thread segment by a second space. A plurality of latch segments includes a first latch segment separated from a second latch segment by a third space. The first space, the second space, and the third space at least partially overlap in along a radial direction of the cap to provide a flex point.

Abstract: The embodiments described herein are directed to a high density polyethylene cap with various flex points that act as hinges or stretch points, whereby the cap behaves similar to a low density polyethylene cap when installed on a bottle neck
