  • Thermoplastic container end for inertial spinwelding of thermoplastic container ends
    Patent number: 4762249
    Abstract: A thermoplastic end (110), particularly a bottom, for a container which has upstanding paperboard sidewalls (112) and which is inertially spinwelded onto the paperboard sidewall for bonding. The end portion (110) has an annular groove (148) for snugly receiving the sidewall (112) and a wall configuration (136, 138, 140, 142 and 144) which minimizes the forces exerted on the bond which would tend to dislodge the end portion. The wall configuration is generally in the form of an inverted U-shape with a portion of an upstanding wall of the U forming a side of the annular groove. The end portion has strengthening ribs (122) positioned generally within the region of U-shape and additional radial ribs imparting strength and rigidity to the container end. The paperboard sidewall may be internally lined with a layer of thermoplastic material or may be unlined.
    Type: Grant
