A screw-coupled refill kit and elastic holder assembly simplify cosmetic stick refilling while improving skin adhesion, absorption, and comfort.

A rotatable support and plug assembly dispenses material from a reusable insert while blocking leakage and reducing single-use packaging waste.

Angled dual nozzles in a monolithic overcap separate spray paths to prevent pooling, improve atomization, and avoid nozzle warpage.

Helical grooves inside the cap store a longer hose within bottle diameter, letting tire sealant reach the valve without hanging from the stem.
