Abstract

A closure includes a base and a lid, the base and lid being joined by a double hinge arrangement so that the lid is movable between a closed position and an open position. The double hinge arrangement includes a first hinge and a second hinge. The lid may be held stably in the open position via tongues or the like, which are provided on or by the lid, base, and/or hinge arrangement.

First claim

The invention claimed is:

1. A closure comprising a base and a lid, the base and lid being joined by a double hinge arrangement so that the lid is movable between a closed position and an open position by means of the double hinge arrangement, the double hinge arrangement comprising a first hinge, a second hinge, and an intermediate panel, the first hinge being connected to the base and the intermediate panel, and the second hinge being connected to the lid and the intermediate panel, and wherein the intermediate panel is provided with a depending tongue and the base is provided with an upstanding tongue such that when the lid is moved to the open position the depending tongue and the upstanding tongue snap past each other to retain the lid in the open position and such that the lid will not return to the closed position without deliberate user action, the closure further comprising a tamper-evident member which is visible prior to first opening of the closure in use, wherein upon the first opening of the closure the tamper-evident member becomes at least partly hidden from view, whereby to indicate the closure has been opened at least once, wherein the tamper-evident member is in the form of a first ring and a second ring connected together by frangible connections, and in which the closure comprises a spout and the tamper-evident member masks at least part of the spout, the lid and the spout or base including projections which engage with corresponding projections on the tamper-evident member such that on the first opening of the closure, the tamper-evident member is pulled apart so that the first ring is pulled by the lid and the second ring is pulled by the base or spout, the frangible connections break such that the tamper-evident member splits into two parts, and the second ring falls into a pocket or void provided in the base so as to become at least partly hidden from view and/or to at least partly reveal at least part of the spout.

2. The closure as claimed in claim 1 , in which the depending tongue and the upstanding tongue are resilient.

3. The closure as claimed in claim 1 , in which a lateral extent of the first hinge is greater than a lateral extent of the second hinge.

4. The closure as claimed in claim 1 , in which the intermediate panel is a generally truncated triangular shape.

5. The closure as claimed in claim 1 , in which the first and/or second hinge is a butterfly hinge.

6. The closure as claimed in claim 1 , in which the first and/or second hinge is a living hinge.

7. The closure as claimed in claim 1 , in which the second hinge is curved or linear.

8. The closure as claimed in claim 1 , in which the first hinge comprises two or more mutually spaced links.

9. The closure as claimed in claim 1 , in which the spout forms part of the base.

10. The closure as claimed in claim 1 , in which the spout is formed separately from the base.

11. The closure as claimed in claim 1 , in which the depending tongue and the upstanding tongue co-operate to cause the lid to be held in the open position.

12. A closure comprising a base and a lid, the base and lid being joined by a double hinge arrangement so that the lid is movable between a closed position and an open position by means of the double hinge arrangement, the double hinge arrangement comprising a first hinge, a second hinge, and an intermediate panel, the first hinge being connected to the base and the intermediate panel, and the second hinge being connected to the lid and the intermediate panel, and wherein the intermediate panel is provided with a depending tongue and the base is provided with an upstanding tongue such that when the lid is moved to the open position the depending tongue and the upstanding tongue snap past each other to retain the lid in the open position and such that the lid will not return to the closed position without deliberate user action, in which the upstanding tongue is provided on the base for engaging the intermediate panel so as to hold the lid in the open position and/or in which the depending tongue is provided on the intermediate panel for engaging the base so as to hold the lid in the open position.
