Abstract: A cap for a reusable bottle and a compound-containing container is provided. The container is a separate, replaceable structure with a base (well/bowl) section containing the compound and a hinged or otherwise removable cap. The container is secured in a cavity in the top of the cap using appropriate detents that flex based upon the materials inherent resilient (e.g. a polymer material) to selectively engage with and disengage from the cap cavity. The cap can include a (unitary or integral) hook or ring that extends from the edges of the cap and can provide a stop that the lid of the secured container hinges against when placed in an open position. The hinge includes a detent adjacent to its front edge (opposite the side containing the hinge). This detent retains the lid in a closed position, but can be overcome by pressure applied by the user to open the lid.

Abstract: A sleeve for a glass bottle includes a first opening, a rounded shoulder below the first opening, a second opening counterposed to the first opening, a rounded shoulder above the second opening, a cylindrical body between the rounded shoulder below the first opening and the rounded shoulder above the second opening when the resides on a bottle. The sleeve is comprised of an elastomeric material and contracts at a point equidistant from the first and second openings when removed from the bottle. The sleeve contraction creates a pinch at the point equidistant from the first and second openings. The pinch is omnidirectional around the circumference of the sleeve. The diameter of the sleeve at the pinch is less than at least one of the diameter of the sleeve at the rounded shoulder below the first opening and the diameter of the sleeve at the rounded shoulder above the second opening.
