Liner Material

Abstract

Provided is container and container closure with a liner material that includes a substrate layer, an active material absorbed into or overlying the substrate layer, and a first protective layer overlying the active material on the top surface of said substrate layer. Optionally, a second protective layer underlies the bottom surface of the substrate layer. The protective layers are impermeable to the active material and are water-soluble. The protective layer precludes release of the active material from the substrate layer so long as the protective layers are intact and undissolved.

1 . A container comprising:
 a container having a container neck;   a container cap attached to the container neck;   a liner material within the container cap comprising;
 a substrate layer comprising, a first protective layer on the top surface of the substrate layer adjacent to the container cap, and a second protective layer on the bottom surface of the substrate layer wherein the second protective layer is water soluble, and 
 an active material within the substrate layer. 
   
   
   
       2 . The container of  claim 1 , wherein the active material is a fragrance. 
   
   
       3 . The container of  claim 1 , wherein one of layers of the substrate layer comprises a material selected from the group consisting of paper, foamed polyethylene, pulp/paper laminations, foamed polyolefin co-extrusions, foamed polyethylene, foamed polypropylene, solid polyolefins, pressure sensitive foamed polyolefins, foam backed induction heat seals, one piece induction heat seals, and laminates and co-extruded combinations thereof. 
   
   
       4 . The container of  claim 1 , wherein the active material is selected form the group consisting of fragrance oils, disinfectants, antimicrobials and combinations thereof. 
   
   
       5 . The container of  claim 1 , wherein the first protective layer and the second protective layer are impermeable to said active material. 
   
   
       6 . The container of  claim 1 , wherein the second protective layer comprises a material selected from the group consisting of polyvinyl alcohols, gelatins, and combinations thereof. 
   
   
       7 . A container comprising:
 a container body having a container neck and filled with a water containing liquid;   a container closure having a closure liner inserted therein wherein the closure liner has a first layer containing an active material and a protective layer on the bottom surface of the first layer wherein the protective layer is exposed the water containing liquid and the protective layer is water soluble.   
   
   
       8 . The container of  claim 7 , wherein the active material is a fragrance. 
   
   
       9 . The container of  claim 7 , wherein the active material is selected form the group consisting of fragrance oils, disinfectants, antimicrobials and combinations thereof. 
   
   
       10 . The container of  claim 7 , wherein the protective layer comprises a material selected from the group consisting of polyvinyl alcohols, gelatins, and combinations thereof. 
   
   
       11 . The container of  claim 7 , wherein the protective layer is impermeable to the active material. 
   
   
       12 . A fragrance release container comprising:
 a container having a container neck;   a container closure having a closure inner surface and a closure outer surface and adapted to fit the container neck; and   a closure seal liner material within the container closure and having a top surface and a bottom surface and comprising a substrate layer, a fragrance within the substrate layer, a first protective layer on the top surface of the substrate layer adjacent to the closure inner surface, and a second protective layer on the bottom surface of the substrate layer,   wherein the liner material is configured such that the liner material is adapted to cooperate with the container closure to form a seal between the container closure and the container, and   wherein the second protective layer is water soluble.   
   
   
       13 . The container of  claim 12 , wherein the closure seal liner is configured as a thin disk inserted into the container closure adjacent the inside surface of the top of the container closure before the container closure is secured on the container. 
   
   
       14 . The container of  claim 12 , wherein the container is inverted after the container is filled with a liquid and after the container closure is secured on the container. 
   
   
       15 . The container of  claim 12 , wherein the second protective layer comprises a material selected from the group consisting of polyvinyl alcohols, gelatins, and combinations thereof. 
   
   
       16 . The container of  claim 12 , wherein the first protective layer comprises a material selected from the group consisting of paper, foamed polyethylene, pulp/paper laminations, foamed polyolefin co-extrusions, foamed polyethylene, foamed polypropylene, solid polyolefins, pressure sensitive foamed polyolefins, foam backed induction heat seals, one piece induction heat seals, and laminates and co-extruded combinations thereof.
