ABSTRACT:
A hollow blow-molded container of a biaxially oriented thermoplastic material in which the container walls contain collapse panels with indentations and reinforcing ribs to accommodate evacuation and permit fabrication of the container without deleterious changes in the appearance of the container. The indentations and ribs within the collapse panels effectively support the collapse panels during contraction of the contents of the container and prevent deformation during fabrication.
