Abstract: An indexing cap assembly indexes visual cues or indicia during an open and close cycle so as to help users more easily track container entry as for example with regard to medications so as to ensure proper dosage. The indexing cap assembly basically incorporates six components, including a cover construction, an indexing plate or wheel, a compression coil or spring, a push plate construction, a gear tray or swing plate construction, and an assembly ring. The cover construction and assembly ring are joined together to essentially form or close the cap assembly with the other parts coaxially aligned and operable therebetween. The indexing wheel is rotatively received within the cover construction such that axial displacements of the push plate advance the indexing wheel and indicia upon its upper surface are sequentially revealed by way of the window formed in the cover construction.

Abstract: A drink bottle with a removable lid includes an inner lid attached to the mouth of the bottle and an outer lid pivotably mounted on the inner lid. A drink spout extends from the inner lid. The outer lid may be locked into a closed position covering the drink spout.
