Problems solved by technology

[0004] A problem with prior art tamper evident closures is that the seal between the closure and container mouth fails before the tamper evident feature works and the tamper evident means is not obvious enough
[0005] A further problem is that air is often present in sealed containers and at least the oxygen and / or moisture contained in the air and oxygen contained in the sealed container and / or may penetrate into the container after sealing may react with the contents and spoil the contents
Said prior art does not disclose the reduction of oxygen or moisture in sealed containers by means of the closures disclosed herein.

Embodiment approach 1

[0067] Embodiment 1 has the connecting side 79A1, viewed from "AA'', as an inclined curved shape with a convex curve; and

Embodiment approach 2

[0068] Embodiment 2 has a connecting side 79A2 as a rectilinear inclined surface; and

Embodiment approach 3

[0069] Embodiment 3 has the connecting side 79A3 as an inclined curved shape with a concave curve when viewed from "AA''; and

[0070] In another embodiment 4, the curved wall 58 between each engagement means 80 extends and intersects the upper surface of the tamper flange 55 at edge 56, as shown by dotted line 58A, And an extension of the engaging surface 78 indicated by the shaded area 78A is formed. The curved wall 58 may have a compound curve with different radii at various points.

[0071] In further embodiments, the wall 58 may be a linear surface rather than a curved surface.

[0072] In yet another embodiment 5, the outer edge of the upper portion of the engagement surface 78 may abut the lower surface 57 of the tamper flange 55 at a position radially inwards towards the axis of the container neck, for example at connection point 82. At least adjacent to the engagement means 80, a portion of the lower surface 57 of the tamper flange abuts the upper surface 55A of the...

Abstract

This invention relates to closures for containers, and more particularly to tamper-evident closures for containers. One aspect of the invention provides a container and a closure for connection to said container, said closure including: an upper wall (102); a skirt (104) formed integrally with and extending downwardly from said upper wall, said skirt adapted to engage with a neck portion of the container to secure the closure to the container; a tamper-evident band (110) frangibly connected to said skirt; the neck of a container including a tamper bead adapted to engage with tabs (122) on said tamper-evident band to facilitate separation of the band (110) from the skirt of the closure and an inwardly and downwardly sloping container neck surface beneath said tamper bead , said inwardly and downwardly sloping surface urging said separated tamper-evident band downwards away from said skirt.

Description

technical field [0001] The present invention relates to closures for containers, and more particularly to tamper-evident closures for containers, and includes tamper-evident dispensing closures and tamper-evident child-resistant closures and corresponding container necks. Background technique [0002] Any discussion of prior art throughout this specification should in no way be taken as an admission that said prior art is widely known or forms part of the common general knowledge in the field. [0003] There is a large amount of prior art related to the design and manufacture of tamper-evident closures for containers, for example, U.S. Patent Nos. Taha), and Australian Patent Application 43435 / 85 (Patent No. 550878), the disclosures of which are incorporated herein by cross-reference. [0004] One problem with prior art tamper evident closures is that the seal between the closure and container mouth fails before the tamper evident feature is activated and the tamper evident...
