Lined container for curable liquid materials

Abstract

A container for transporting and storing a curable composition comprising a container and a liner of a surface treated plastic. The liner is bonded to a cover about the periphery of the cover, preferably with the material contained within the container.

1 . A lined container comprising: 
 a container for at least one curable composition derived from phenolic and amino resins, acrylics, polyurethanes or epoxies and comprising an interior wall surface having at least one opening and defining an enclosed cavity;    a removable liner adjacent at least a portion of the interior wall surface having a closure region consisting essentially of a surface treated plastic film, which inner liner is conformable generally with the shape of the cavity; and    a top closure comprising at least one plastic layer and an impermeable layer; the top closure film having a size such that when placed above liquid in the container a portion of the plastic layer of the top closure and a portion of the liner are disposed adjacent to one another at a juncture so as to form a closed structure above the contained liquid; and wherein the top closure is sealed by bonding the liner to the closure with the curable composition and forming a moisture and air impermeable seal at the juncture.    
   
   
       2 . The container of  claim 1 , wherein the liner is selected from a corona treated liner, a plasma treated liner, a flame spray treated liner or a combination thereof.  
   
   
       3 . The container of  claim 1 , wherein the liner is a multilayered plastic film.  
   
   
       4 . The container of  claim 2 , wherein the lined container further comprises a desiccant pack.  
   
   
       5 . The container of  claim 1 , wherein the liquid is a composition curable by moisture, UV radiation, heat, air or a combination thereof.  
   
   
       6 . The container of  claim 5 , wherein the liquid is a moisture-curable polyurethane.  
   
   
       7 . The container of  claim 1 , wherein the top closure is a laminate film comprising an impermeable layer between a layer of polyester and a layer of polyethylene.  
   
   
       8 . The container of  claim 1 , wherein the liner is bonded to the interior surface of the container prior to filling with the liquid.  
   
   
       9 . The container of  claim 3 , further comprising a patch having at least one plastic layer and an impermeable layer, wherein the patch is adapted cover a dispensing port located through the closure and bond to the closure with the curable composition thereby forming a moisture and air impermeable seal at the dispensing port.  
   
   
       10 . The container of  claim 1 , wherein the sealant is a composition including a polyurethane prepolymer.  
   
   
       11 . A container filled with liquid comprising: 
 a container comprising an interior wall surface having at least one opening and defining an enclosed cavity;    a removable liner adjacent at least a portion of the interior wall surface comprising a surface treated plastic film, which inner liner is conformable generally with the shape of the cavity;    at least one curable composition derived from phenolic and amino resins, acrylics, polyurethanes or epoxies filling at least a portion of the lined structure such that a portion of the inner liner extends beyond the liquid contained by the container; and    a top closure film comprising at least one plastic layer and an impermeable layer; the top closure film having a size such that when placed above liquid in the container a portion of the plastic layer of the top closure and a portion of the liner are disposed adjacent to one another at a juncture so as to form a closed structure above the contained liquid; and wherein the top closure is sealed by bonding the liner to the closure with the curable composition and forming a moisture and air impermeable seal at the juncture.    
   
   
       12 . The container of  claim 11 , wherein the liner is a multilayered film.  
   
   
       13 . The container of  claim 11 , wherein the liner includes a metal layer.  
   
   
       14 . The container of  claim 13 , wherein the top closure is a laminate film comprising an impermeable layer between a layer of polyester and a layer of polyethylene.  
   
   
       15 . The container of  claim 11 , further comprising a patch having at least one plastic layer and an impermeable layer, wherein the patch is adapted cover a dispensing port located through the closure and bond to the closure with the curable composition thereby forming a moisture and air impermeable seal at the dispensing port.  
   
   
       16 . The container of  claim 15 , wherein the sealant is a composition including a polyurethane.  
   
   
       17 . A container filled with liquid comprising: 
 a metal container comprising an interior wall surface having at least one opening and defining an enclosed cavity;    a removable liner adjacent at least a portion of the interior wall surface comprising a surface treated polyolefin film, which inner liner is conformable generally with the shape of the cavity, the liner being selected from a corona treated liner, a plasma treated liner, a flame spray treated liner or a combination thereof;    a moisture curable polyurethane composition filling at least a portion of the lined structure such that a portion of the liner extends beyond the moisture curable polyurethane composition contained in the container; and    a top closure film comprising at least one plastic layer and an impermeable layer; the top closure film having a size such that when placed above liquid in the container a portion of the plastic layer of the top closure and a portion of the liner are disposed adjacent to one another at a juncture so as to form a closed structure above the contained liquid; and wherein the top closure is sealed by bonding the liner to the closure with the curable polyurethane composition and forming a moisture and air impermeable seal at the juncture.    
   
   
       18 . The container of  claim 17  wherein the container further comprises a desiccant located in a headspace region within the container and above the top closure film.  
   
   
       19 . The container of  claim 17 , wherein the liner is a multilayered film.  
   
   
       20 . The container of  claim 19 , wherein the top closure is a laminate film comprising an impermeable layer between a layer of polyester and a layer of polyethylene.  
   
   
       21 . The container of  claim 17 , further comprising a patch having at least one plastic layer and an impermeable layer, wherein the patch is adapted cover a dispensing port located through the closure and bond to the closure with the curable composition thereby forming a moisture and air impermeable seal at the dispensing port.
