Definitions

  • This invention relates to caps for containers, more particularly bottles, having screw-threaded necks and to combinations of such caps and containers.
  • U.S. Patent Specification No. 2990079 discloses a screw-cap for a container, the internal screw-thread ridge of the cap having venting notches in its length.
  • the top of the screw-cap forms a diaphragm which is movable, by excess gas pressure in the container to which the cap is applied, to relieve the excess pressure even when the cap is tightly applied.
  • U.S. Patent Specification No. 4007848 discloses arrangements in which an external screw-thread on the neck of a container is notched to provide an escape route for gas during removal of a cap from the container.
  • U.S. Specification No. 3888347 discloses a capped container for fluid-pressurized balls e.g. tennis balls.
  • the cap is screw-threaded on to the container and a groove extends axially of the screw-thread ridge of the cap to provide an escape path for the gas within the container.
  • a seal between the cap and the container is formed by a sealing element disposed at the underside of the top of the cap and held captive within the cap but permitting rotation of the sealing element relative to the cap.
  • the cap when tightly applied, the cap maintains a gas-tight seal on the container, but the pressure in the container is relieved during removal of the cap, gas escaping across the screw-thread by way of the notches as soon as the gas-tight seal is broken and while the screw-thread on the cap is well engaged with the thread on the container.
  • notches in successive turns of the -thread are preferably formed in axial alignment with each other so as to shorten the escape path.
  • the container with which the cap is associated in use may have its screw-thread ridge similarly formed with a plurality of transverse venting notches spaced along its length, notches in successive turns of the thread on the container being substantially axially aligned with each other.
  • the notch may have a radial depth equal to or less than the radial height of the thread-forming ridge.
  • the distance measured along the ridge between adjacent notches may differ.
  • the distances between adjacent notches may be greater at either end of the ridge than the other.
  • Figures 1 and 2 show a cap 15 according to the invention.
  • the cap is moulded in one piece from a suitable plastics material and has an internal screw-thread ridge 16 which is formed with a series of transverse notches 17 spaced along its length. The radial depth of the notches is equal to the radial height of the ridge 16.
  • An annular sealing fin 18 and rib 19 and an annular surface 20 are provided to form a pressure-tight seal with the uppermost portions of the screw-threaded neck portion of a container.
  • Figures 3 and 4 show the neck portion 21 of such a container in the form of a bottle with an external helical ridge 22 constituting the screw-thread.
  • the portion 24 of the neck above the thread has a closely controlled external diameter and forms a seal with the surface 20, fin 18 and rib 19 of the screw cap.
  • the seal with portion 24 is broken whilst the screw-threads on the cap and bottle are still well engaged, and any pressure in the bottle is then relieved by flow of gas past the sealing surfaces and thence through the notches 17 in the cap and round the profile of the complementary thread-cutting ridge of the bottle.
  • the ridge 22 of the bottle is preferably formed with aligned transverse notches 23 as shown, to shorten the escape path of the gas, but may if desired be uninterrupted.

Claims (5)

1. Aus Kunststoffmaterial geformte Schraubkappe mit einer Stirnwand und einem herabhängenden Mantel, der zur Bildung einer gewendelten Schraubengewinderippe (16) auf seiner radialen Innenfläche ein Schraubengewinde aufweist und der über dem Schraubengewinde mit einem inneren Teil (18, 20) versehen ist, der einstückig an die Schraubkappe angeformt ist und um die Mündung eines Behälters eine gasundurchlässige Dichtung mit dem Behälter bilden soll, wobei in der Schraubengewinderippe mehrere quergerichtete Durchtrittskerben (17) ausgebildet sind, die über die Länge der Rippe gegenseitigen Abstand haben.
2. Schraubkappe nach Anspruch 1, bei der die Kerben in aufeinanderfolgenden Windungen der Rippe axial miteinander fluchten.
3. Schraubkappe nach Anspruch 1 oder Anspruch 2, bei der jede Kerbe aus einer Unterbrechung in der Rippe besteht, so daß die radiale Tiefe der Kerben im wesentlichen gleich der Höhe der Rippe ist.
4. Schraubkappe nach Anspruch 1 oder Anspruch 2, bei der die radiale Tiefe der Kerben geringer ist als die radiale Höhe der Rippe (16).
5. Schraubkappe nach irgendeinem der vorangehenden Ansprüche in Kombination mit einem Behälter, der einen Hals (21) mit äußerem Schraubengewinde aufweist, in dessen Schraubengewinderippe mehrere über ihre Länge verteilte, quergerichtete Durchtrittskerben (23) ausgebildet sind, wobei Kerben in aufeinanderfolgenden Windungen des Gewindes miteinander axial im wesentlichen fluchten.
