ABSTRACT:
Lightweight, strong, thermoplastic foamed crates for storage and shipment of tender or fragile materials, especially produce such as fruit and vegetables, are prepared from (a) an extruded base and side panel structural foamed thermoplastics and (b) end plates and a divider or dividers which are injection molded foamed thermoplastic materials. This combination of materials reduces the number of molds and molding operations required to provide a large number of containers, since only end pieces and dividers need be molded and carried in inventory.
The containers may also have perforated end plates to provide for ventilation or cooling as well as a ridged base or flooring to provide drainage and containment for juices of decaying produce.
In addition to providing superior insulating qualities regarding loss of heat or refrigeration, the all-foam crate construction provides improved vibration dampening characteristics which in turn prevent bruising or breakage of tender or fragile items during transportation.
