Liner-based assembly for removing impurities
View Patent ↗The present disclosure relates to a liner for storing a material, the liner including at least two layers, wherein a layer that is in contact with the material is an active layer. The active layer may be made active by incorporating a scavenger into the layer. At least one layer of the liner may comprise a polymer or a fluoropolymer. In some embodiments, the active layer may be configured for removing microbridging components in photoresists. In some embodiments, the active layer may be made active by coating the interior of the layer with an inert material, such as glass. In further embodiments, the liner may be positioned within a stainless steel canister. The present disclosure also relates to a liner-based assembly for storing a material, an overpack within which the liner is positioned, and a purifying packet positioned between the liner and the overpack.
1. A liner-based assembly comprising:
a collapsible liner for storing a material, the collapsible liner including at least two layers,
wherein at least one of the layers is an active layer;
an overpack within which the collapsible liner is positioned; and
a purifying packet positioned between the collapsible liner and the overpack,
wherein the active layer is configured for removing microbridging components in photoresists.
2. The liner-based assembly of claim 1 , wherein the active layer is made active by incorporating a scavenger into the layer.
3. The liner-based assembly of claim 2 , wherein at least one layer of the flexible liner comprises a polymer.
4. The liner-based assembly of claim 2 , wherein at least one layer of the flexible liner comprises a fluoropolymer.
5. The liner-based assembly of claim 1 , wherein the active layer is made active by coating the interior of the layer with an inert material.
6. The liner-based assembly of claim 5 , wherein the inert material comprises glass.
7. The liner-based assembly of claim 1 , wherein the overpack is a stainless steel canister.
8. The liner-based assembly of claim 1 , wherein the purifying packet comprises a scavenger.
9. A liner-based assembly comprising:
a container for storing a hazardous gas;
a barrier bag within which the container is positioned; and
a getter positioned between the container and the barrier bag.
10. The liner-based assembly of claim 9 , wherein the getter comprises a permeable packaging containing a material capable of attracting or reacting with a hazardous gas stored in the container.
11. The liner-based assembly of claim 10 , wherein the getter comprises a portion configured to change color when the material reacts with the hazardous gas from the container, thereby indicating gas has leaked from the container.
12. The liner-based assembly of claim 10 , further comprising a second outer container within which the barrier bag and the container within the barrier bag are positioned.
13. The liner-based assembly of claim 12 , further comprising a getter positioned between the outer container and the barrier bag.
14. The liner-based assembly of claim 1 , wherein the collapsible liner is a flexible liner.
