MOLDED PLASTIC ARTICLES HAVING CURVATURE IN THREE DIMENSIONS

摘要

A tape dispenser comprises a housing comprising a face portion and a sidewall proximate the face portion. The face portion and the sidewall each comprise an inner surface and an outer surface. The outer surface of the sidewall is curved in the x-y plane, contains no undercuts and comprises a plurality of ribs extending across it. The ribs are convexly curved in the z-axis. The inner surface of the sidewall is linear in the z-axis. The inner surface of the face portion comprises a tape holding portion adapted to hold a roll of tape therein. The curvature of the inner surface of sidewall encircles more than half of a roll of tape held by the tape holding portion. The housing is integrally molded from a polymeric material.
