Abstract

Multi-compartmentalized container system includes a container having a lid member and a tray member. The lid member includes a plurality of first recesses formed on a bottom surface of the lid member and opening in a first direction, a membrane disposed over the first recesses to retain contents of the first recesses, and at least one second recess formed on an opposite surface to the bottom surface of the lid member and opening in a second direction opposite the first direction. The lid member is releasably lockable to the tray member by placing the bottom surface of the lid member toward the tray member.

Claims (23)

1. A multi-compartmentalized container system comprising a container comprising:

a lid member comprising

a plurality of first recesses formed on a bottom surface of the lid member and opening in a first direction,

a membrane disposed over the first recesses to retain contents of the first recesses, and

at least one second recess formed on an opposite surface to the bottom surface of the lid member and opening in a second direction opposite the first direction;

a tray member, wherein the lid member is releasably lockable to the tray member by placing the bottom surface of the lid member toward the tray member; and

an insertable container releasably lockable to the lid member by placing the insertable container within the at least one second recess of the lid member.

2. The container system of claim 1 , wherein the lid member comprises polystyrene, polypropylene, polyethylene terephthalate, polylactide, polyvinyl chloride, or other rigid polymers.

3. The container system of claim 1 , wherein the tray member comprises polystyrene, polypropylene, polyethylene terephthalate, polylactide, polyvinyl chloride, or other rigid polymers.

4. The container system of claim 1 , wherein the lid member is constructed using a process selected from the group consisting of thermoforming, injection molding, transfer molding and blow molding.

5. The container system of claim 1 , wherein the tray member is constructed using a process selected from the group consisting of thermoforming, injection molding, transfer molding and blow molding.

6. The container system of claim 1 , wherein the membrane is a foil.

7. The container system of claim 1 , wherein the container is stacked with at least one additional container of similar configuration to form a stack of containers.

8. The container system of claim 1 , wherein the lid and tray members are releasably lockable using a snap-fit mechanism.

9. The container system of claim 1 , wherein the lid and tray members form a tamper-resistant seal.

10. The container system of claim 1 , wherein the lid and tray members form a tamper-evident seal.

11. The container system of claim 7 , wherein the stack of containers is sized for display in a retail setting.

12. The container system of claim 1 , wherein the at least one second recess borders at least one of the first recesses.

13. The container system of claim 1 , wherein the at least one second recess is disposed between at least two of the first recesses.

14. The container system of claim 1 , wherein the lid member is formed from a sheet of polymer material.

15. The container system of claim 1 , wherein the tray member is formed from a sheet of polymer material.

16. The container system of claim 1 , wherein the insertable container has a smaller cross dimension than the lid member.

17. The container system of claim 1 , wherein the insertable container is sized to be disposed entirely within the at least one second recess.
