Reusable packaging and storage

1. A consumer product comprising:

a reusable article which is a packaging and storage article having a top member and a bottom member configured to releasably engage with each other; and

an elastic constriction ring having a central aperture and comprising a tubular ring of resilient elastic material;

wherein the bottom member comprises:

a cavity of substantially circular shape having a perimeter lip with an inner and outer surface to house, in use, a portion of the elastic constriction ring; and

a pillar extending from a substantially central portion of the cavity of the bottom member;

wherein a summit of the pillar has a diameter less than the diameter of the central aperture of the elastic constriction ring, and a lower portion of the pillar has a diameter greater than the diameter of the central aperture of the elastic constriction ring;

wherein the pillar is configured with an impingement point such that, in storage of the elastic constriction ring in the article, a bottom surface of the elastic constriction ring is suspended above an upper surface of the cavity of the bottom member; and

wherein the top member comprises:

a cavity of substantially circular shape having a perimeter lip with an inner and outer surface to house, in use, a portion of the elastic constriction ring;

wherein the diameter of an inner surface of the perimeter lip of the top member is the same or greater than the diameter of the outer surface of the perimeter lip of the bottom member.

2. The consumer product according to claim 1 , wherein the cavity of the bottom portion defines a tubular shape.

3. The consumer product according to claim 1 , wherein the perimeter lip of the bottom member is at the same height as the impingement point of the pillar.

4. The consumer product according to claim 1 , wherein the perimeter lip of the top member is provided with a height that is substantially the same as the height of the perimeter lip of the bottom member such that when the top member and bottom member are engaged with each other when the article is in a closed position, the perimeter lip of the bottom member is secured within and adjacent to the perimeter lip of the top member.

5. The consumer product according to claim 1 , wherein the perimeter lips of both the bottom member and the top member are sized to form frictional contact with each other when the top member and the bottom member are engaged with each other and the article is in a closed position.

6. The consumer product according to claim 5 , wherein the frictional contact between the perimeter lips is sufficient to provide a closure mechanism to releasably retain the top and bottom members in the closed position.

7. The consumer product according to claim 1 , wherein one or both of the top member and the bottom member is provided with one or more vent holes.

8. The consumer product according to claim 1 , wherein the article is made as a single piece construction.

9. The consumer product according to claim 8 , wherein the article is made of a plastic material.

10. The consumer product according to claim 9 , wherein the article is injection moulded, blow-moulded or thermoformed.

11. The consumer product according to claim 1 , wherein the pillar is conical or frusto-conical in shape.

12. The consumer product according to claim 11 , wherein the pillar is frusto-conical in shape.

13. The consumer product according to claim 1 , wherein the elastic constriction ring consists of the tubular ring of resilient elastic material.
