Abstract: Apparatus that uses the burster method for positioning coupons from a continuous web at a predetermined time at a predetermined location for insertion is disclosed. Positioning rolls define a bight to receive the leading edge of a coupon and are driven by positioning drive assembly. A feed drive assembly advances coupons to the positioning rolls. Sensors actuate and deactuate the feed drive assembly in response to the presence of a container at a selected position and the presence of a coupon at another sensing position.

Abstract: A three-dimensional insert for use in a handling system comprising a sheet of cardstock or the like defined by ends and first and second sides, a laminate applied to the top surface of the cardstock, and an overwrap material bonded to the laminate proximate to the first and second sides. This structure enables a three-dimensional object to be placed within the overwrap material without risk of movement to the peripheral sides.

Abstract: Apparatus that uses the burster method for positioning coupons from a continuous web at a predetermined time at a predetermined location for insertion is disclosed. Positioning roll means define a bight to receive the leading edge of a coupon and are driven by positioning drive means at a continuous predetermined speed. Feeding roll means located upstream of the positioning roll means in the excess of one coupon length are driven by intermittent feeding drive means at a speed substantially less than the speed of the positioning roll means. Controlling means actuate and deactuate the feeding drive means in response to timing means related to container position and coupon sensing means at a sensing position between the positioning roll means and the feeding roll means.

Abstract: A container of blow-moulded oriented thermoplastic material includes a base structure comprising a convex annular surface (which may be divided into a plurality of feet (118) by radial webs (112) and a central re-entrant portion (116). In blow-moulding the container, a moulded preform is enclosed within a mould heated, and stretched such that its bottom surface impinges upon a projecting surface of the mould bottom corresponding to the topmost surface (158) of the re-entrant portion. After blow-moulding, the material of the re-entrant portion (116) remains unoriented and relatively thick in comparison to the material of the remainder of the base. The unoriented material in the base is substantially confined to the re-entrant portion (116) which itself is strengthened by its relatively thick walls and the base thus exhibits improved creep and stress cracking properties.
