Definitions

  • This invention relates to an easy open closure.
  • it relates to an easy open closure for a container designed to be closed under vacuum and to a container provided with such a closure.
  • the traditional method of closing a vacuum-type container comprises simply placing the closure over the open end of the container so that the vacuum created in the container causes the closure to adhere to the container.
  • a tight seal is obtained by the use of a gasket or sealing compound provided between the container body and the closure.
  • the present invention seeks to provide a closure which improves the openability of a vacuum container whilst not unduly increasing the cost of manufacturing the closure.
  • an easy open closure for a container having a rigid body and being adapted to be closed under vacuum comprising a panel, a tab connected to the panel, and a score in the panel, the tab being suitable for rupturing the score and releasing the vacuum.
  • the tab is located close to the score and may substantially cover the score.
  • Easy-open ends are known for example for metal containers for carbonated drinks, in which a tab is generally riveted to a central panel of the end.
  • a closure portion of the end is defined by a score line which can be broken by lifting a rear portion of the tab so as to detach the closure portion from the rest of the central panel thus providing an aperture through which product may be extracted from the container.
  • ends and associated technology are well-known for beverage containers, for example, no suitable opening of this kind has been developed as a closure for vacuum containers.
  • the closure may be rigid and may therefore be used as a loose cover after opening the container to protect the product inside, since only a small vent hole will be present in the closure when the score is broken.
  • the primary function of the tab of the present invention is to break at least part of the score so as to release the vacuum.
  • the tab does not break the score so as to provide an aperture in the closure through which a product can be removed from the container as in a beverage container, for example.
  • the release of the vacuum enables the whole closure to be removed by simply lifting the closure, without needing to tear away the whole score or to provide access to the product via an aperture in the closure.
  • a container having a rigid body and provided with a closure as described above.
  • Figure 1 is a plan view of a closure according to the present invention
  • Figure 2 is a perspective view of the closure of figure 1 in use fixed to a vacuum container
  • Figure 3 is a perspective view of the container of figure 2 after opening, with a portion of the closure cut away.
  • a container 10 (figures 2 and 3) and a metal closure 20.
  • the container body 10 is made of a rigid material suitable for withstanding a vacuum, for example of plastics or glass.
  • the closure 20 comprises a concave panel 25 having a peripheral flange 30 which has an inner groove on its underside in which a gasket or sealing compound 40 (figure 3) is provided.
  • the closure 20 fits on the container body 10 and the top edge of the container is embedded in the sealing compound 40 so that an air tight seal is formed when a vacuum pulls the closure onto the container body.
  • the closure 20 includes an easy opening device or tab 60 comprising a gripping ring or ring pull 70 and a lug 90 attached to the centre of the panel 25 by a rivet 95.
  • the lug portion of the tab substantially covers a U-shaped score 80 (dotted line in figure 1).
  • the tab is thus arranged so as to rupture the score 80 when the tab is lifted away from the panel by the gripping ring 70.

Abstract

Fermeture (20) destinée à un récipient sous vide (10) et comprenant un panneau (25) ainsi qu'une languette (60) reliée à ce dernier, laquelle recouvre une marque (80). La languette est agencée de manière à rompre la marque lorsqu'une partie arrière de ladite languette est soulevée à partir dudit panneau, libérant ainsi le vide se trouvant à l'intérieur du récipient. L'accès à un produit contenu dans le récipient est alors possible simplement par soulèvement de la fermeture.
