초록 ▼

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. During spinwelding, a sidewall supporting mandrel having an expansible engaging portion is inserted into the sidewall and subsequently expanded to define a cylindrical surface of a diameter equal to that of the specified internal diameter of the sidewall. A Teflon seating member at the end of the sidewall supporting mandrel establishes the depth to which the container end is inserted into the sidewall.

A container end, adapted to receive a container sidewall and to be spinweld bonded thereto, comprising; a first portion for receiving a container sidewall, said first portion comprising a first annular groove formed by first and second upstanding wall members; a second portion, connected to an end of said second wall member at a position remote from said first wall member and having means for transferring to a direction normal to a spinwelded bond, any shear forces which arise due to axial forces on said container end which tend to shear said spinweld bond, said second portion comprising an additional wall portion connected to and extending from said second wall member and forming therewith a second annular groove of generally opposite orientation from said first annular groove, wherein said shear force transferring means comprise a plurality of circumferentially spaced radial ribs, extending in said second annular groove between said second upstanding wall portion and said additional wall portion, said plurality of ribs being operable to transfer forces acting on said container end from shearing said spinwelded bond and being further operable to provide a rotary drive engagement for said container end.
