Abstract

A container includes a container body (201), optionally a lid (220), and an insert (100) secured, optionally fixedly secured within an interior of the container body. The insert has a base material, optionally a polymer, for providing structure to the insert, and a desiccant. The insert further has an opening leading to an interior compartment (102) configured for housing products and an outer surface (104) facing an inner surface of the container body. A void is provided between an exposed portion of the outer surface of the insert and a portion of the inner surface of the container body. At least one fluid pathway is provided between the void and the interior compartment of the insert.

First claim

What is claimed is:

1. A container comprising:
a container body having a base and a sidewall extending therefrom, the container body having an inner surface defining an interior of the container body, the container body further having an opening leading to the interior;
a lid movable with respect to the container body to move the container between a closed position in which the lid covers the opening and an open position in which the opening is exposed; and
an insert secured within the interior of the container body, the insert comprising a base material and a desiccant, wherein the base material provides structure to the insert, the insert having an opening leading to an interior compartment configured for housing products and an outer surface facing the inner surface of the container body,
wherein a void is provided between an exposed portion of the outer surface of the insert and a portion of the inner surface of the container body, and
wherein at least one fluid pathway is provided between the void and the interior compartment of the insert, the at least one fluid pathway being provided through a plurality of thru holes in the insert, each of the plurality of thru holes extending through a sidewall or a bottom wall of the insert from an exterior surface of the insert to the interior compartment configured for housing products.

2. The container according to claim 1 , wherein the insert further has a bottom end portion and a top-edge portion disposed opposite the bottom end portion; wherein the top-edge portion defines the opening leading to the interior compartment.

3. The container according to claim 2 , wherein a plurality of protrusions are provided on: a) the outer surface of the insert, or b) the inner surface of the container body; wherein the plurality of protrusions engage the inner surface of the container body.

4. The container according to claim 3 , wherein the plurality of protrusions comprises ridges provided on the outer surface of the insert; and wherein the ridges extend longitudinally from proximate the top-edge portion to proximate the bottom end portion.

5. The container according to claim 4 , wherein at least one of the ridges is tapered from the top-edge portion to the bottom end portion.

6. The container according to claim 4 , wherein the ridges are evenly spaced from one another.

7. The container according to claim 3 , wherein the plurality of protrusions comprises detents provided on the outer surface of the insert; and wherein the detents extend from the bottom end portion away from the top-edge portion.

8. A container comprising:
a container body having a base and a sidewall extending therefrom, the container body having an inner surface defining an interior of the container body, the container body further having an opening leading to the interior;
a lid movable with respect to the container body to move the container between a closed position in which the lid covers the opening and an open position in which the opening is exposed; and
an insert secured within the interior of the container body, the insert comprising a base material and a desiccant, wherein the base material provides structure to the insert, the insert having an opening leading to an interior compartment configured for housing products and an outer surface facing the inner surface of the container body, the insert further has a bottom end portion and a top-edge portion disposed opposite the bottom end portion, wherein the top-edge portion defines the opening leading to the interior compartment, and wherein the at least one fluid pathway is provided through: a) at least one thru hole in the insert, or b) at least one gap between the top-edge portion and the inner surface of the container body, the insert further having an annular-shaped lip extending radially outwardly from the top-edge portion to the inner surface of the container body,
wherein a void is provided between an exposed portion of the outer surface of the insert and a portion of the inner surface of the container body, and
wherein at least one fluid pathway is provided between the void and the interior compartment of the insert.

9. The container according to claim 1 , wherein the container body further has an annular-shaped retention ring extending radially inwardly from the inner surface of the container body in order to retain the insert within the container body.

10. The container according to claim 1 , wherein the lid is linked to the body by a hinge.

11. The container according to claim 1 , wherein the lid comprises a lid sealing surface; wherein the container body further has a body sealing surface disposed about the opening leading to the interior of the container body; and wherein the body sealing surface and the lid sealing surface are configured to mate to form a moisture tight seal between the lid and the body when the container is in the closed position.

12. A container comprising:
a container body having a base and a sidewall extending therefrom, the container body having an inner surface defining an interior of the container body, the container body further having an opening leading to the interior and a body sealing surface is disposed about the opening;
a lid movable with respect to the container body to move the container between a closed position in which the lid covers the opening and an open position in which the opening is exposed, the lid comprising a lid sealing surface; and
an insert secured within the interior of the container body, the insert comprising a base material and a desiccant, wherein the base material provides structure to the insert, the insert having an opening leading to an interior compartment configured for housing products and an outer surface facing the inner surface of the container body,
wherein a void is provided between an exposed portion of the outer surface of the insert and a portion of the inner surface of the container body,
wherein at least one fluid pathway is provided between the void and the interior compartment of the insert,
wherein the body sealing surface and the lid sealing surface are configured to mate to form a moisture tight seal between the lid and the body when the container is in the closed position, and
wherein the container has a moisture ingress of less than 1000 micrograms per day, at 80% relative humidity and 22.2 degrees C.

13. The container according to claim 1 , wherein the insert comprises a blend of the base material and the desiccant.

14. The container according to claim 13 , wherein the insert is an entrained polymer further comprising a channeling agent.

15. The container according to claim 1 , wherein the insert has a total exposed surface area that is at least 1.75 times an exposed surface area of the interior compartment.

16. The container according to claim 1 , wherein the insert is a single, unitary member.

17. The container according to claim 1 , wherein the void is provided between both: (a) a bottom end of the insert and the base of the container body; and (b) the outer surface of the insert and the sidewall of the container body.

18. An insert for a container, the insert comprising:
a bottom end portion; and
a top-edge portion disposed opposite the bottom end portion, a sidewall extending from the bottom end portion to the top-edge portion, the top-edge portion defining an opening leading to an interior compartment configured for housing product,
wherein a plurality of thru holes extend through the insert, the plurality of thru holes being configured to serve as a fluid pathway from or to the interio
