Latchable package

1. A latchable package comprising:

a support for supporting one or more items,

a structure for selectively blocking access to the one or more items; and

a substantially planar tab member comprising an upper side and a lower side, the tab member being coupled to the support such that the tab member and support are movable together in a single opening direction from a first position in which the structure blocks access to the one or more items to a second position in which the one or more items are accessibly clear of the structure; wherein:

the structure and the tab member comprise co-operating latch features configured to engage when the tab member and support are arranged in the first position;

the tab member is coupled to a base of the support;

the base of the support defines a first plane, the lower side of the substantially planar tab member defines a second plane, and the upper side of the substantially planar tab member defines a third plane, wherein each of the second plane and the third plane are substantially parallel to the first plane when the tab member and the support are in the first position, and the second plane is spaced from the third plane by a thickness of the substantially planar tab, and

the tab member lies against the base of the support when the tab member and the support are in the first position, such that the tab member and the support are stacked.

2. The latchable package of claim 1 , wherein the support comprises a tray.

3. The latchable package of claim 1 , wherein the latch feature of the tab member comprises one or more latch formations.

4. The latchable package of claim 3 , wherein the latch feature of the structure comprises one or more abutment surfaces against which the one or more latch formations abut to engage co-operating latch features.

5. The latchable package of claim 4 , wherein the abutment surfaces are defined by an aperture on the structure.

6. The latchable package of claim 5 , wherein, when the package is in the first position, and the latch features are engaged, the one or more latch formations of the tab member protrudes through the aperture of the structure.

7. The latchable package of claim 3 , wherein the support comprises an aperture through which the one or more latch formations of the tab member protrude.

8. The latchable package of claim 7 , wherein the aperture of the support is provided on a side wall of the support.

9. The latchable package of claim 1 , wherein coupling between the tab member and the support is effected by arranging the tab member substantially inside the support.

10. The latchable package of claim 1 , wherein the latchable package comprises a withdrawal stop structure for limiting movement of the support in the opening direction.

11. The latchable package of claim 10 , wherein the withdrawal stop structure comprises cooperating formations on the support and the structure.

12. The latchable package of claim 11 , wherein the cooperating formations comprise opposed abutment surfaces on the support and on an internal surface of the structure.

13. The latchable package of claim 12 , wherein at least one of the opposed abutment surfaces is defined by a withdrawal stop latch movable into a latch position with respect to the support or the structure.

14. The latchable package of claim 13 , wherein the withdrawal stop latch is a flap on the support or the structure.

15. The latchable package of claim 1 , wherein, in the second position, the support protrudes from a first end of the structure, wherein a second end of the structure opposite the first end comprises an access opening configured to permit access to an end of the support to allow the support to be pushed in the opening direction by a user's finger while the latch features are in a disengaged state, and wherein a base wall of the structure is provided with a channel configured to permit the user's finger to move in the opening direction whilst pushing the support.

16. The latchable package of claim 15 , wherein the channel is defined by a cut-out in the base wall of the structure.

17. The latchable package of claim 16 , wherein:

the access opening is defined by a cut-out in an end wall of the structure; and

the access opening and the channel are defined by a single cut-out.

18. The latchable package of claim 16 , wherein the channel has a length in the opening direction and a width perpendicular to its length, the length being at least 1.5 times the width.
