ORTHOPEDISCHE STEUNVERPAKKING EN WERKWIJZE VOOR DE VERVAARDIGING ERVAN.

摘要

A package containing an orthopedic support (A) constructed of open cell foam material comprises a bag (B) which is formed of heat sealable, thermoplastic, multi-layered film and which is sealed along a single open edge after insertion of the support which may have been compressed, therethrough. The orthopedic support is compressed in the bag to reduce an irregular height dimension by a major amount with displacement of a corresponding amount of air from the bag through its open edge prior to heat sealing. A collapsed 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 tendency of the orthopedic support to expand so creating a partial vacuum in the bag. The compression of the support in the bag is obtained by using a press platen with a press bed, said platen or bed having a facing of yieldable material. Stop means for limits the movement of the press platen and bed toward each other.
