Abstract
A shipping container for dunnage, such as automotive engines, is disclosed having a rigid frame and a pair of spaced apart dunnage support members which are secured to the frame. The dunnage support members each have upwardly extending portions which are adapted to abut against and support selected areas of the dunnage. These upwardly extending portions are constructed of a material formed by the isothermal reaction of isocyanate and a resin which are selected such that the elastomeric material resulting from the isothermal reaction is essentially devoid of entrapped air bubbles. A method for forming the dunnage support members is also disclosed.
Claims5
A shipping container for dunnage comprising:
- a rigid frame,
- at least one dunnage support member, said dunnage support member having upwardly extending portions adapted to abut against and support selected areas of the dunnage,
- means for securing said dunnage support member to said frame,
- wherein said upwardly extending portions are constructed of an elastomeric material formed by the reaction of isocyanate and resin, said resin and isocyanate being selected such that said elastomeric material is essentially devoid of entrapped gas bubbles.
A method for constructing a dunnage support member having a shape adapted to abut against and support selected areas of dunnage comprising the steps of:
- evacuating air from a source of isocyanate,
- intermixing said isocyanate from said source with a resin from a second source i n a closed mold chamber conforming in shape to the dunnage support member, said isocyanate and resin undergoing an isothermal reaction in the mold chamber which results in a hard elastomeric material essentially devoid of gas bubbles,
- removing the dunnage support member from the mold chamber following solidification of the isocyanate and resin,
