Abstract

A closure for a container comprising a circular base (20), a skirt (30) extending from the periphery thereof, an outer seal (60) and a plug seal (50) in the form of an annulus and at least one rib (80) lying on the surface of the base (20) in a substantially radial direction and in contact with the radially inner surface of the plug seal (50) at one end for transferring any movement of the base (20), relative to the skirt (30), to the plug seal (50) such that the plug seal (50) is pulled radially inward to allow venting of excess pressure within the container, whereby the outer seal (60) of the closure comprises at least one deformation portion (65) which interrupt partially the sealing effect of the outer seal (60) in case overpressure occurs.

Description

  • The present invention relates to a closure according to the preamble of the independent claim.
  • Screw closures for containers with pressurized fluids such as carbonated beverages are widely known. If the pressure build-up in the container exceeds a desired level sufficient to overcome the thread engagement, the closure may be suddenly ejected from the container neck, an effect also called "closure missiling" which may lead to possible injury of users.
  • Closures for container have therefore been developed, whereby excessive gas pressure in the container is decreased by automatic self-venting of the closure-container arrangement in the sense of a pressure control valve.
  • EP 0 858 416 discloses a closure with a base and a downwardly depending skirt defining the outside of the closure. Within the closure, a bore seal downwardly depends from the base. Radially between this bore seal and the skirt, a stop also downwardly depends from the base. This stop acts to prevent over-tightening of corresponding screw threads located within the shell and on an associated container, and acts against the rim of the container. Between the stop and the bore seal the thickness of the base is thinned. A rib of uniform thickness lying on the inside of the base extends from the bore seal towards the axial centre of the base and the bore seal is bulged radially outwardly by its presence in case of overpressure, whereby the container is vented.
  • The venting mechanism of EP 0 858 416 functions in that the thinned portion as described works as a hinge allowing the portion of the base, including the part which has the bore seal depending from it, to move upwards. Hence, the bore seal has to be lifted slightly from the inner side of the container neck to allow venting.
  • WO 2006/051068 discloses a closure suitable for self-venting of excessive gas by a rib which is lying on the surface of its base and in direct contact with a bore seal and transfers any movement of the centre of the base by excessive gas to that bore seal allowing venting.
  • In accordance with self-venting mechanism of WO 2006/051068 the bore seal moves away from the inner side of the container because of its direct contact to the neck.
  • The bore seal disclosed in these documents seals by pressing against the inner side of the neck of the container when the closure is applied. In this context, it is a known problem that damages or tortures at the rim or within the neck reduce the sealing effect.
  • Therefore, in case of damages or tortures at the inner surface of the container neck, such arrangements for self-venting further reduce the desired sealing effect of the bore seal or lead to premature venting intensifying the problem as mentioned.
  • It is therefore the object of the present invention to overcome the drawback of the prior art and in particular to provide a closure which supports the functionality of such bore seal to improve the sealing properties and thereby not decreasing the workability of the self-venting function.
  • This problem is solved with a closure according to the characterizing part of claim 1.
  • The invention provides a closure for a container comprising a circular base, a skirt extending from the periphery thereof, a plug seal in the form of an annulus, typically also called dive seal, and at least one rib lying on the surface of the base in a substantially radial direction.
  • The plug seal seals the closure against the inner side of the container. The rib is in contact with the radially inner surface of the plug seal at one end for transferring any movement of the base, relative to the skirt, to the plug seal such that the plug seal is pulled radially inward to allow venting of excess pressure within the container.
  • An outer seal is arranged concentrically to the skirt. Such outer seal seals against an outer surface of the container weal and further centers the closure against the container and generates a counterforce to the plug seal supporting its sealing properties against the container neck.
  • The outer seal has at least one deformation portion which is weaker than a main fraction of the outer seal and which will interrupt partially the sealing effect of the outer seal in case overpressure occurs. Such a deformation portion maintains the desired functionality of automatical self-venting, whereas, especially at normal gas and ambient temperature conditions in the container, the sealing effect at the position of such deformation portion is as effective as at the main fraction of the outer seal. The deformation portion may be formed by locally reducing the size of the seal, e.g. its axial length and/or by its radial thickness. The deformation portion might also be formed by influencing the material properties. The deformation portion may even break when extreme pressure conditions are built up inside the container.
  • The closure preferably comprises 6 main fraction and deformation portions, respectively, if the circular base has a diameter of 28mm. The closure preferably comprises 8 or 9 main fractions and deformation portions, respectively, if the circular base has a diameter of 38mm.
  • The closure provides further preferably a top bulge located at the under side of the upper wall between the plug seal and the outer seal. The top bulge features at least one gap whereby excessive gas can pass through. Thereby, in addition to the deformation portions, a defined route for the gas to escape strengthens the effect of self-venting.
  • Preferably, the top bulge is arranged concentrically to and between the plug seal and the outer seal
    There is some free radial space between the top bulge and the outer seal such that excessive gas can reach and pass the deformation portion. However, preferably the gap of the top bulge is circumferentially aligned with the deformation portion to guarantee a defined and direct route for excessive gas, thereby increasing the effect of the self-venting.
  • The outer seal of the closure is preferably arranged vertically to the circular base or may be inclined slightly radially inwardly or outwardly. Such inclination of the outer seal will reduce the surface contact and thereby reduce friction, in order to keep removal torques low.
  • The end of the rib in contact with the radially inner surface of the plug seal is preferably thinner, in a plane parallel to the base, than in a region spaced from the end of the rib in contact with the radially inner surface, in particular thinner than the other end of the rib. A relatively thin contact to the plug seal brings several advantages such as a minimized reduction of the flexibility of the plug seal. Such an arrangement is described in WO 2006/051068 .
  • The deformation portion may be formed by reduction of the radial thickness of the outer seal.
  • Preferably, the rib is aligned to a deformation portion in order to shorten the way of excessive gas when venting.
  • The deformation portions are preferably located in a constant circumferential distance to each other.
  • The radial angle included between the deformation portions is preferably between neighbourly internal sides of 34° to 50°, more preferably between 34° to 45°, most preferably 34° to 40°. A constant distance between the deformation portion leads to a homogeneous force allocation and centering when the closure is applied to the container. Furthermore, self-venting is effected homogeneously over the whole circumference of the outer seal.
  • Furthermore, the thickness of those deformations portions is preferably between 0.3 to 0.5 mm, more preferably between 0.3 to 0.4 mm, as compared to a thickness of 0.7mm of the outer seal.
  • The circumferential length of the deformation portion is determined by a radial angle from the centre of the circular base including preferably between 6° to 30°, more preferably between 6° to 20° , most preferably between 6° to 15°.
  • Embodiments of the inventions will now be described, by way of example, with reference to the following drawings.
