Abstract
A container for transporting and storing a liquid comprising an outer container; an inner liner and a top closure film, both inner liner and top closure being films comprising at least one plastic layer and an impermeable layer, and a sealant disposed above the level of contained liquid and between the juncture of the inner liner and top film. The inner liner and top closure are preferably laminate films having an inner, air impermeable (e.g., metal foil) layer between a first plastic (e.g., polyester) layer and a second plastic (e.g., polyethylene) layer.
Claims20
A container filled with liquid comprising:
- a form providing structure defining an enclosed cavity of predetermined shape and having an opening;
- an inner liner of a film comprising at least one plastic layer and an impermeable layer which is positioned in the cavity of the structure, which inner liner conforms generally to the predetermined shape of the structure;
- liquid filling at least a portion of the lined structure such that a portion of the inner liner extends beyond the liquid contained by the structure;
- a top closure film comprising at least one plastic layer and an impermeable layer;
- the top closure film having a size such that a portion of the plastic layer of the top closure film and a portion of the plastic layer of the inner liner are disposed adjacent to one another so as to form a closed film structure above the contained liquid;
- and
- a sealant comprising a curable or cured composition derived from phenolic and amino resins, acrylics, polyurethanes or epoxies disposed above the level of contained liquid and between the juncture of the inner liner and top laminate films, thereby bonding the inner liner to the top closure film and forming a moisture and air impermeable seal at the juncture, wherein the inner liner and top closure film are removable from the form.

A container filled with liquid comprising:
- a form providing structure defining an enclosed cavity of predetermined shape and having a fill opening;
- an inner liner of a laminate film comprising an impermeable layer between a layer of polyester and a layer of polyethylene which is positioned in the cavity of the structure, which inner liner conforms generally to the shape of the structure and is positioned in the cavity so that the polyethylene layer is closest to the inner surface of the structure;
- liquid filling at least a portion of the lined structure such that a portion of the inner liner extends beyond the liquid contained by the structure;
- a top laminate closure film comprising an impermeable layer between a layer of polyester and a layer of polyethylene placed on the surface of the liquid with the polyester layer being closest to the liquid and having a size such that at least a portion of the top laminate film overlaps the contained liquid such that a portion of the polyester layer of the inner liner and a portion of the polyester of the top film are disposed adjacent to one another so as to form a closed film structure above the contained liquid;
- and
- a sealant comprising a curable or cured composition derived from phenolic and amino resins, acrylics, polyurethanes or epoxies disposed above the level of contained liquid and between the juncture of the inner liner and top laminate films, thereby bonding the inner liner to the top closure film and forming a moisture and air impermeable seal at the juncture, wherein the inner liner and top closure film are removable from the form.

A container filled with liquid comprising:
- a form providing structure defining an enclosed cavity of predetermined shape and having a fill opening;
- an inner liner of a laminate film comprising an impermeable layer between a layer of polyester and a layer of polyethylene which is positioned in the cavity of the structure, which inner liner conforms generally to the shape of the structure and is positioned in the cavity so that the polyethylene layer is closest to the inner surface of the structure;
- liquid filling at least a portion of the lined structure such that a portion of the inner liner extends beyond the liquid contained by the structure;
- a top laminate closure film comprising an impermeable layer between a layer of polyester and a layer of polyethylene placed on the surface of the liquid with the polyester layer being closest to the liquid and having a size such that at least a portion of the top laminate film overlaps the contained liquid such that a portion of the polyester layer of the inner liner and a portion of the polyester of the top film are disposed adjacent to one another so as to form a closed film structure above the contained liquid;
- and
- a sealant comprising a moisture-curable polyurethane disposed above the level of contained liquid and between the juncture of the inner liner and top laminate films, thereby bonding the inner liner to the top closure film and forming a moisture and air impermeable seal at the juncture, wherein the inner liner and top closure film are removable from the form.
