Desiccating container for moisture-sensitive material
First Claim
1. A container having within it contents comprising a moisture sensitive material and an atmosphere, the container comprising a container body of a substantially atmospheric moisture-impermeable material and having an opening sealed by a closure, the closure having an inner face exposed to said contents, at least a part of said closure being made of a desiccating polymer and forming at least a part of said inner face, the desiccatitng polymer being an elastomeric material compounded with a filler, the elastoneric material further including a sufficient quantity of a desiccating material to absorb enough moisture from said contents of the container to reduce degradation of the moisture sensitive material by water and water vapour, the closure also comprising a closure wall having a puncturable region therein in direct communication with the interior of the container.

- 1. A container having within it contents comprising a moisture sensitive material and an atmosphere, the container comprising a container body of a substantially atmospheric moisture-impermeable material and having an opening sealed by a closure, the closure having an inner face exposed to said contents, at least a part of said closure being made of a desiccating polymer and forming at least a part of said inner face, the desiccatitng polymer being an elastomeric material compounded with a filler, the elastoneric material further including a sufficient quantity of a desiccating material to absorb enough moisture from said contents of the container to reduce degradation of the moisture sensitive material by water and water vapour, the closure also comprising a closure wall having a puncturable region therein in direct communication with the interior of the container.
- 25. A container for a moisture sensitive material in the form of a vial, having a container body of glass and having an opening sealed by a closure which closure is wholly made of halobutyl rubber compounded with a filler and a desiccating material selected from the group consisting of molecular sieve, calcium oxide, and mixtures thereof, and wherein the desiccating material replaces from about 10 to 50% of the weight of the filler, the closure comprising a closure wall having a puncturable region therein in direct communication with the interior of the container.

27. A method of desiccating potassium clavulanate in combination with crystalline sodium amoxycillin which comprises enclosing potassium clavulanate in combination with crystalline sodium amoxycillin in a container with a closure, the closure comprising a dessicatintg polymer and maintaining the desiccating polymer in contact with the atmosphere inside said container, the desiccating polymner being an elastomeric material compounded with a desiccating material which material provides the dessicating activity in said container.
- 29. A closure for a vial, containing a mouth opening, which closure is formed from an elastomeric material compounded with a filler and a desiccating material, and wherein the desiccating material replaces from about 10 to 50% of the weight of the filler, the closure comprising a closure wall having a puncturable region therein in direct communication with the interior of the vial.
