Abstract

A container for receiving moisture sensitive goods includes a container body (15) and a cap (26) shaped to establish a leak-proof seal between the container body and the cap. The container body has a base and a sidewall with an insert element present inside the container body having a bottom and an insert sidewall, wherein an outer circumferential surface of the insert sidewall is in contact with an inner circumferential surface of the sidewall of the container body. The bottom of the insert element is permeable to moisture and the insert sidewall and the sidewall of the container body are designed to attach the insert element inside the container body. In addition, the container has a desiccant chamber between the bottom of the insert element and the base of the container body for receiving desiccant material.

Claims

1. A container for receiving moisture sensitive goods comprising:

a container body and a cap;

wherein the cap and the container body are shaped to establish, in a closed state, a leak-proof seal between the container body and the cap;

wherein the container body comprises a base and a sidewall extending upwards from the base;

an insert element comprising a bottom and an insert sidewall, wherein the insert element is contained within an interior of the container body, such that an outer circumferential surface of the insert sidewall is in abutting contact with an inner circumferential surface of the sidewall of the container body;

wherein the bottom of the insert element is permeable to moisture;

wherein the insert sidewall and the sidewall of the container body are designed to attach the insert element inside the container body; and

wherein the container further comprises a desiccant chamber between the bottom of the insert element and the base of the container body for receiving a predetermined amount of desiccant material.

2. The container according to claim 1,

characterized in that

the insert element is comprised of a desiccant polymer.

3. The container according to claim 1,

characterized in that

the bottom of the insert element comprises multiple openings.

4. The container according to claim 1,

characterized in that

the bottom of the insert element comprises a membrane or a permeable film.

5. The container according to claim 4,

characterized in that

a moisture vapour transmission rate (MVTR) of the bottom of the insert element is at least 1.5 times, as high as a moisture vapour transmission rate of the sidewall of the insert element.

6. The container according to claim 1,

characterized in that

the insert sidewall and the sidewall of the container body are provided with a locking geometry element to attach the insert element inside the container body in a predetermined position.

7. The container according to claim 6,

characterized in that

the locking geometry element comprises an annular recess in the inner circumferential surface of the sidewall of the container body for receiving the insert sidewall.

8. The container according to claim 1

characterized in that

the cap is connected via a hinge to the container body;

wherein

the hinge comprises a mechanical hinge comprising a pivot element of the container body to which the cap is rotatably attached.

9. The container according to claim 1,

characterized in that

the cap is integrally formed with the container body, and a hinge is formed by a bendable section with a cross-sectional area between the container body and the cap.

10. The container according to claim 1,

the seal between the container body and the cap comprises a sealing skirt depending from a top of the cap, which, in the closed state of the cap, sealingly engages with an opening of the container body.

11. A method of manufacturing the container according to claim 1, comprising the steps:

(a) introducing desiccant material into the container body;

(b) inserting the insert element into the container body;

(c) fixing the insert element in a defined position relative to the container body; and

(d) closing the cap on the container body.

12. The container of claim 5 characterized in that the moisture vapour transmission rate of the bottom of the insert element is at least 2 times as high as the moisture vapour transmission rate of the sidewall of the insert element.

13. The container of claim 5 characterized in that the moisture vapour transmission rate of the bottom of the insert element is at least 3 times as high as the moisture vapour transmission rate of the sidewall of the insert element.
