Molded case for returnable beverage bottles

摘要

A bottle case integrally molded from thermoplastic resin has at least one separator column subdivided into partial pillars rising from the floor of the case for separating bottles in the case sufficiently to prevent breakage in handling and transportation. Each column is subdivided by a gap so that bottles can be accepted together with a carrier or minicase, with one internal wall of one carrier or minicase or one external wall of each of two carriers or minicases being slid into the gap of the column. The pillars have single-webbed profiled walls, the surface of the profiled wall facing the side walls of the box structure being part of side faces of the column and the other surface of the profiled wall being part of the gap configuration. The upper mouth of the gap can be a slot to facilitate insertion of the carrier or minicase and to locate and adjust its walls. Vertical reinforcement corrugations stabilize the pillars. A web of material of reduced length fills the gap between the facing edges of the pillars adjacent the floor. The pillars are anchored to a floor lattice by anchoring points which include at least points located on the outside of the pillars directly opposite inner reinforcement ribs.
