Caps and closures like push-turn bottle caps with easy grip sides, push-turn dropper caps, and align-arrow-pop top bottle caps are some of the most common senior-friendly closures on medication bottles. There are also options for all-in-one senior-friendly child-resistant containers like single-dose packets, slide mechanism-push blister packs and squeeze-pop containers. Single-dose packets and blister packs also help prevent accidental overdose for seniors that may have memory problems. Plastic bottles and caps made from HDPE, PP, and LDPE are pliable and provide better gripping for seniors.
