Benefits of technology

[0007] The present invention is a container assembly for retaining a moisture-sensitive material. The container assembly has a container defining a sealed chamber. A humidity control substance is disposed within the chamber of the container and is

Problems solved by technology

When opened for access to those materials, however, there may be an exchange of moisture between the air inside the container and the air outside the container.
There may also be an exchange of moisture between the air inside the container and the air outside the container if there is an air leak in the container.
The exchange of moisture may adversely affect the properties of the moisture-sensitive material stored in the container.
The quality of moisture-sensitive material may be affected if the moisture level (also known as the “humidity level”) of the air inside the container falls below or rises above a desi

Embodiment Construction

[0013] The present invention is a container assembly having a material storage container for retaining a moisture-sensitive material, where a desired moisture level is controlled inside a chamber of the container by a humidity control substance. The humidity control substance regulates the moisture level inside the chamber of the container (i.e., buffers changes in moisture level) in order to maintain a moisture content of the moisture-sensitive material within a desired range of moisture content. The moisture-sensitive material may be any healthcare-related material, including, but not limited to, pharmaceutical products, medical products and devices, or dental materials or products, such as, but not limited to one or more capsules containing a dental material composition or dental materials, such as, but not limited to, glass ionomers, resin modified glass ionomers, dental adhesives, orthodontic adhesives, cements, restoratives, coatings, varnishes, sealants, and / or composite crow...

Abstract

A container assembly has a material storage container defining a sealed chamber therein. A quantity of moisture-sensitive material is disposed in the chamber. The moisture-sensitive material has a desired range of moisture content. A hydrated humidity control substance is also disposed within the chamber, and the humidity control substance is in humidity-transferable communication with the chamber. The humidity control substance regulates a relative humidity within the chamber in order to maintain a moisture content of the moisture-sensitive material within the desired range of moisture content.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S) [0001] This application claims the benefit of U.S. Provisional Application No. 60 / 640,558, filed Dec. 30, 2004 and U.S. Provisional Application No. 60 / 640,975 filed Jan. 3, 2005.BACKGROUND OF THE INVENTION [0002] The present invention relates to a container and method for retaining a moisture-sensitive material. More specifically, the present invention relates to a container that has a moisture-sensitive material and a humidity control substance, where the humidity control substance regulates a relative humidity within a chamber of the container in order to help the moisture-sensitive material maintain a desired range of moisture content. [0003] Moisture-sensitive materials, such as pharmaceutical products, are often stored in hermetically and waterproof resealable containers. When opened for access to those materials, however, there may be an exchange of moisture between the air inside the container and the air outside the container. There ...
