Abstract

A head stand container closure is provided. The closure comprises a base, and a lid having a top plate upon which the closure rests in use. The base is attachable to a container and the lid is attached or attachable to the base. The closure comprises an internal tamper-evident member comprising a part which is initially spaced from the lid top plate and upon first opening of the closure the part moves to or towards the top plate when the head is in a head down orientation.

First claim

The invention claimed is:

1. A head stand container closure, the closure comprising a base, and a lid having a top plate upon which the closure rests in use, the base is attachable to a container and the lid is attached or attachable to the base, the closure comprises an internal tamper-evident member, wherein the tamper-evident member comprises a first ring and a second ring connected together by frangible bridges, the first ring remains fixed in the base of the closure and substantially without any possible vertical movement and the second ring is located in the lid of the closure, initially spaced from the top plate of the closure lid, and arranged so that it can slide to the top plate of the closure lid, in which upon first opening of the closure lid the frangible bridges break and a space is created between the two rings, and in which during the first opening the second ring becomes secured within the lid, adjacent to the top plate of the closure, and in which after reclosing the lid on the body of the closure the space between the two rings remains such that previous opening of the closure is clearly apparent to a user.

2. A closure as claimed in claim 1 , in which at least part of the closure is transparent.

3. A closure as claimed in claim 1 , in which the base is attachable to a container.

4. A closure as claimed in claim 1 , in which the second ring moves to the top plate by falling to its position under gravity.

5. A closure as claimed in 1 , in which the base ring is clipped onto a base bead and the lid ring is retained by a lid bead.

6. A closure as claimed in 5 , in which the base includes a top deck and the base bead is formed on the top deck, and in which the lid includes a skirt which depends from the top plate, the lid bead is formed on the skirt.

7. A closure as claimed in claim 1 , in which the lid includes a generally cylindrical sidewall, the sidewall depends from the top plate.

8. A closure as claimed in claim 1 , wherein the lid is connected to the base by a hinge.

9. A head stand pack comprising a head standable flip-top dispensing closure in combination with a container, the closure comprises a base and a lid, the lid is connected to the base by a hinge, the base includes a top deck with a dispensing aperture, the container includes a neck and the base is connected to the container neck, the lid includes a top plate, the top plate is generally flat and adapted to form a stable base on which the container can stand with the closure in a head down orientation, the closure comprising tamper-evident means which activate upon first opening of the lid and provide a visible indication of opening when the closure is in the head down orientation, wherein the tamper-evident means comprises a base ring which is retained by the base and a lid ring which is retained by the lid, the rings are initially connected together frangibly and are separated when the lid is opened for the first time, with the lid ring falling down onto an interior face of the lid top plate.

10. A closure as claimed in claim 9 , in which the base ring includes a flap for locking it onto the base and in which the lid ring includes a bead for retaining it in the lid.

11. A head stand container closure, the closure comprising a base, and a lid having a top plate upon which the closure rests in use, the base being attachable to a container and the lid being attached or attachable to the base, the closure comprises an internal tamper-evident member, in which the tamper-evident member comprises a base ring which is retained by the base and a lid ring which is retained by the lid, the rings being initially connected together frangibly and separated when the lid is opened for the first time, in which the base ring is clipped onto a base bead and the lid ring is retained by a lid bead.

12. A closure as claimed in claim 11 , wherein the lid is connected to the base by a hinge.
