Drinking cup with open ribbed sidewall
摘要:
A drinking cup having bottom and sidewalls which define a liquid holding cavity. The sidewalls include a plurality of vertical ribs which are formed therein with an open base disposed toward the liquid holding cavity. The ribs are present in sufficient numbers to assure that the surfaces of the ribs are the primary contact point between the user's hand and the cup. The sidewall construction provides both improved insulation and strength characteristics. The cup finds particular use with geriatric users.
