Abstract

A case is provided for holding one or more contact lenses. The case is configured to receive an inner pod, and the case includes an upper part and a lower part. The upper part is structured to move relative to the lower part from an open configuration wherein the upper and lower parts are at least partially separated to a closed configuration wherein the upper and lower parts are together. The upper part is also structured to move relative to the lower part from a disengaged position to an engaged position wherein, in the disengaged position, the case is movable between the open and closed configurations and in the engaged position, the case is locked in the closed configuration.

First claim

The invention claimed is:

1. A case for holding one or more contact lenses, the case configured to receive an inner pod, wherein
the case comprises an upper part and a lower part, the upper part structured to move relative to the lower part from an open configuration wherein the upper and lower parts are at least partially separated to a closed configuration wherein the upper and lower parts are together, and
the upper part structured to move relative to the lower part from a disengaged position to an engaged position wherein, in the disengaged position, the case is movable between the open and closed configurations and in the engaged position, the case is locked in the closed configuration wherein the upper part comprises a cover mounted on a compression member, the cover mounted for movement such that the cover rotates with respect to the compression member, and the upper part includes an annulus, the annulus positioned between the cover and the compression member, arranged to apply pressure to the compression member when the case is in the engaged position.

2. A case according to claim 1 , including a drain for draining liquid that would otherwise be retained in the case.

3. A case as claimed in claim 2 , wherein the lower part has one or more hole for receiving the inner pod, wherein the hole(s) also function as the drain.

4. A case according to claim 1 wherein the upper part is connected to the lower part by a hinge.

5. A case according to claim 1 wherein the cover has grooves to accommodate protrusions on the outer surface of the annulus, so that when the case transitions between engaged and disengaged positions, the annulus remains fixedly connected to the compression member, whilst the cover moves with respect to both the compression member and annulus.

6. A case according to claim 1 wherein when the case transitions between open and closed configurations, the annulus remains fixedly connected to both the compression member and cover.

7. A case according to claim 1 wherein the compression member comprises an elastomeric material.

8. A case according to claim 1 wherein the compression member has one or more raised portions and, in the engaged position, the one or more raised portions of the compression member are configured to contact the lid of a pod in the case, forming a seal at the one or more raised portions.

9. A case according to claim 1 wherein the compression member is directly connected to the lower part by a hinge and the cover is indirectly connected to the lower part by the hinge via the compression member.

10. A case according to claim 1 further comprising an inner pod, the inner pod comprising a base portion defining one or more compartments and a re-sealable lid, wherein, when the case is in the engaged position, the inner pod is compressed between the upper and lower parts, the upper part structured to apply pressure to the lid to seal the one or more compartments.

11. A case according to claim 10 wherein, in the closed configuration, the inner pod is retained in the case and in the open configuration, the inner pod is removable from the case.

12. A case according to claim 10 wherein the lid is a film lid having a re-sealable first region and a second region that is fixed to the base portion.

13. A case according to claim 10 wherein the lid seals the one or more compartments around the compartments, the seal being closer to the compartments than to the outer edge of the lid.

14. A case according to claim 10 wherein the lower part has a threaded portion and the upper part has a threaded portion, and, rotation from the disengaged to the engaged position causes the threaded portions to interlock such that the inner pod is compressed.

15. A case according to claim 10 wherein, in the open position, the inner pod is releasably retained in the case.

16. A case according to claim 15 , including one or more retaining clips for retaining the inner pod within the case.

17. A case according to claim 10 wherein the one or more compartments of the inner pod contains a lens care solution suitable for contact lenses.

18. A kit of parts for holding one or more contact lenses including:
a plurality of inner pods, each inner pod including a base portion defining one or more compartments and a re-sealable lid; and
the case of claim 1 , for receiving an inner pod selected from the plurality of inner pods.

19. A kit of parts according to claim 18 wherein the inner pod contains a solution of a first composition and the plurality of pods includes at least one second inner pod containing a solution of a second, different, composition.
