发明名称 Orthopedic support package and method
摘要 A package for containing an orthopedic support constructed of open cell foam material may comprise a bag constructed of heat sealable thermoplastic multilayered film which is sealed along a single open edge after insertion of the orthopedic support therethrough into the bag. The orthopedic support is differentially compressed to such an extent as to reduce an irregular height dimension by a major amount with evacuation of a corresponding amount of air from the bag through the open edge prior to application of the heat seal along the open edge. An evacuated marginal portion of the bag extends outwardly about the orthopedic support by an amount corresponding to the reduction in height of the orthopedic support and results from the partial vacuum in the bag and the tendency of the open cell foam to rebound. The differential compression is obtained by using a press in compressing relationship with a press bed, applying compression to an extent which may be predetermined by utilizing a suitable stop means for limiting relative movement of the press members toward each other.
