Abstract

A container assembly configured to maintain a predetermined humidity for storing a product therein. The container assembly includes a container having a body with a body wall and a mouth opening into a storage cavity and a cap having a top wall. The cap is selectively mountable over the mouth of the container to substantially enclose the storage cavity in a mounted configuration. A sidewall extends substantially perpendicularly from one of the body wall and the top wall. The sidewall defines an opening and a compartment and has an opening edge adjacent the opening. A moisture control material is positioned within the compartment. A sealing membrane has a peripheral portion. The peripheral portion is secured to the sidewall proximate the opening edge. The sealing membrane is configured to allow moisture flow therethrough to maintain the predetermined humidity in the storage cavity.

Claims

1. A container assembly configured to maintain a predetermined humidity for storing a product therein, the container assembly comprising:

a container having a body with a body wall, a bottom wall and a mouth;

a cap having a top wall, the cap selectively mountable over the mouth of the container in a mounted configuration;

a vertical wall comprising a lower portion of the body wall and extending substantially perpendicularly from the bottom wall, an opening edge proximate a top of the vertical wall, the opening edge defining an opening, a compartment defined between the bottom wall, the vertical wall and the opening and the opening edge being defined by a groove that extends inwardly from the body wall, the groove includes an upper rib and a lower rib;

a storage cavity defined between the opening, an upper portion of the body wall, and the mouth;

a moisture control material positioned within the compartment;

a sealing membrane having a peripheral portion, the peripheral portion secured proximate the opening edge, the sealing membrane configured to allow water vapor or moisture flow therethrough to maintain the predetermined humidity in the storage cavity, and

a compartment lid having a lid edge, a cavity surface and a compartment surface, the compartment lid connected to the opening edge with the compartment surface facing the compartment and the cavity surface facing the storage cavity in an assembled configuration, the lid edge positioned between the upper and lower ribs in the assembled configuration.

2. The container assembly of claim 1, wherein the cap is connected to the body by a living hinge proximate the mouth.

3. The container assembly of claim 1, wherein the sealing membrane is secured to the compartment surface of the compartment lid.

4. The container assembly of claim 1, wherein the compartment lid includes a plurality of perforations therethrough, the plurality of perforations facilitating the flow of water vapor and moisture through the compartment lid and the sealing membrane.

5. The container assembly of claim 1, wherein the opening edge is defined by a horizontal wall that extends inwardly into the storage cavity from the body wall.

6. The container assembly of claim 1, wherein the cap is snap fit over the mouth to cover the mouth in a closed configuration.

7. The container assembly of claim 1, wherein the opening edge is defined by a horizontal wall that extends inwardly from the body wall.

8. A container assembly configured to maintain a predetermined humidity for storing a product therein, the container assembly comprising:

a container having a body with a body wall, a bottom wall and a mouth, the mouth positioned adjacent a top end of the body wall, a vertical wall comprised of a lower portion of the body wall;

a cap having a top wall and a downwardly depending wall, the cap selectively mountable over the mouth of the container to substantially enclose the container in a mounted configuration;

a horizontal wall extending inwardly from the body wall at a top of the vertical wall, the horizontal wall defining an opening edge and an opening, the opening, horizontal wall, vertical wall and bottom wall defining a compartment and the opening, the horizontal wall, an upper portion of the body wall, and the mouth defining a storage cavity;

a moisture control material positioned within the compartment;

a sealing membrane having a peripheral portion secured to the horizontal wall proximate the opening edge; and

a compartment lid having a lid edge, a cavity surface and a compartment surface, the compartment lid connected to the horizontal wall proximate the opening edge with the compartment surface facing the compartment and the cavity surface facing the storage cavity, the sealing membrane attached to the compartment surface with the peripheral portion adjacent the lid edge, the sealing membrane configured to allow water vapor or moisture flow therethrough to maintain the predetermined humidity in the storage cavity.

9. The container assembly of claim 8, wherein the compartment lid includes a perforation extending between the cavity surface and the compartment surface.

10. The container assembly of claim 8, wherein the compartment lid has a substantially circular, disc-like shape, the opening edge having a substantially circular shape, the compartment lid positioned with the lid edge on the horizontal wall in an assembled configuration.

11. The container assembly of claim 8, wherein the cap is connected to the container by a living hinge, the living hinge integrally molded between the cap and the container.

12. The container assembly of claim 8, wherein the sealing membrane is adhesively bonded to the compartment surface.

13. The container assembly of claim 8, wherein the cap, the container and the compartment lid are constructed of a polymeric material.
