  • Container having collapse panels with longitudinally extending ribs
    Patent number: 4805788
    Abstract: A hollow blow-molded container of a biaxially oriented thermoplastic material in which the container walls contain collapse panels with ribs to accommodate evacuation of the container without deleterious changes in the appearance of the container.
