Abstract (en)
[origin: EP0293901A1] A closure for a container comprises a top 11 with a depending skirt 12 having an internal screw thread. Where the skirt joins the top, the internal surface 15 of the skirt is conically flared in a direction away from the top, and a flexible resilient fin 18 extends from the underside of the top substantially parallel to the flared surface 15. When the closure is applied to the neck of a container, the fin 18 becomes deformed outward and is sufficiently long to extend round the outer corner portion of the top of the container to a location on or contiguous to a cylindrical outer surface of the neck of the container and is pressed into tight sealing engagement with said outer corner portion by the flared surface. The free end portion of the fin may have an increased thickness, which causes it to resist expansion and to hug more closely to the outer corner portion of the neck of the container. The radially inner surface of the fin may have one or more annular ribs thereon, for example of triangular shape.
