Abstract: A chip or debris trap or collector retains chips, fragments and other debris generated when a serrated or splined, press fit connection is assembled between a shaft and another component such as a housing, gear, pulley or bearing. The chip collector includes a circumferential channel or groove disposed about the shaft adjacent the ring of serrations or male splines and an adjacent circumferential flange. An optional second channel or groove resides in the other component. As the shaft and the component are assembled, chips, fragments or other debris generated by the interference fit and axial sliding assembly of the components are collected in the channel or channels and retained there as the shaft fully seats within the other component.

Abstract: A disposable cup assembly having an improved coupling system for connecting a container and lid together is disclosed herein. In some embodiments, the coupling system is configured to reduce or eliminate the likelihood of the container contents from spilling when the disposable cup assembly is tipped over or used. The container, in some embodiments, can have threading along the top portion of the container that can preferably be configured to couple with a lid having a threaded flange and can create a robust connection or fitting between the lid and container.
