Abstract: A marker storage accessory includes a main body having marker-engaging structure and writing surface engaging structure. The main body may also include cap-engaging structure or, alternatively, blocking structure. The marker-engaging structure includes a plurality of circumferentially positioned teeth adapted to be conformingly inserted into the complementarily shaped channels defined by the ribs located on the non-writing end of a writing instrument such as a dry-erase marker. The cap-engaging structure can include ribs creating a geometry adapted to conformingly receive the protruding end of a cap for the writing instrument. The blocking structure can be a protrusion adapted to prevent attachment of the marker storage accessory on the nub-end of the writing instrument while permitting attachment of a marker cap. When the marker storage accessory is attached to the writing surface, the marker self-positions to a generally nub-down orientation.

Abstract: A self-contained composition dosing and delivery system provides an efficient device to store and deliver materials, particularly liquids, in a safe and controlled manner. The device also provides a dosing element internal the device chamber, thus eliminating the need for additional components. In particular, the device itself may be used to deliver liquid medicine and other compositions which are liquids, or gel-like, in controlled amounts or doses. The device may also include child-proof mechanism, or child safety feature to reduce child poisoning due to Over-the-Counter (OTC) medication overdoses.
