## Abstract

The invention relates to a laminate liner for sealingly engaging a container in an associated container and closure assembly. The liner can include at least first, second, third, and fourth layers, respectively, and have a thickness between 0.0060-0.0120 inches. The first and bottom layer, can comprise a plastic polymeric material, and have a thickness between 0.0005-0.0015 inches. The second layer can comprise a metallic material and have a thickness between 0.0005-0.0010 inches. The third layer can comprise a chip board material, and have a thickness between 0.0045-0.0055 inches. The third layer can prevent the liner from curling or deforming from its preferably flat shape. The fourth and top layer can comprise a plastic polymeric material and have a thickness between 0.0005-0.0015 inches. An adhesive bonding layer, having a thickness between 0.0003-0.0005 inches, can be located between first, second, third, and fourth layers, to bond adjacent layers together.

## Claims

### Claim 1

A liner configured to engage a closure, the liner consisting of four layers and an adhesive:
Each layer being secured to an adjacent layer by the adhesive;
Said layers consisting of:
a first layer comprising a first polymeric material, the first layer having a first thickness between 0.0005 inches and 0.0015 inches;
a second layer adjacent the first layer, the second layer comprising a metallic material, and the second layer having a second thickness between 0.0005 inches and 0.0010 inches;
and
a fourth layer adjacent a third layer comprising a second polymeric material, the fourth layer having a fourth thickness between 0.0005 inches and between 0.0015 inches;
wherein the improvement is the third layer adjacent the second layer consisting of a pulp based material configured to resist curling and having a thickness from 0.0045 to 0.0055 inches;
wherein the liner is thereby configured to engage and seal the closure, without curling.

### Claim 2 (depends on 1)

The liner of claim 1 wherein the first and second polymeric materials comprise a plastic material.

### Claim 3 (depends on 1)

The liner of claim 1 wherein the third thickness is 0.0045 inches.

### Claim 4 (depends on 1)

The liner of claim 1, the adhesive having a fifth thickness between 0.0003 inches and 0.0005 inches.

### Claim 5

A liner configured to sealingly engage an opening of a container, the liner consisting of four layers and an adhesive;
Each layer secured to an adjacent layer by the adhesive;
said plurality of layers consisting of:
a first layer comprising a first polymeric material, wherein the first layer has a thickness between 0.0005 inches and 0.0015 inches;
a second layer adjacent the first layer, the second layer comprising an aluminum foil, wherein the second layer has a thickness between 0.0005 inches and 0.0010 inches;
a third layer adjacent the second layer, the third layer consisting of a pulp-based material configured to assist in resisting deformation of the entire liner and having a thickness between 0.0045 inches and 0.0055 inches; and
a fourth layer adjacent the third layer, the fourth layer comprising a third polymeric material, wherein the fourth layer has a thickness between 0.0005 inches and to 0.0015 inches;
wherein the liner is configured to sealingly engage the container without deforming.

### Claim 6 (depends on 5)

The liner of claim 5, the liner having a thickness between 0.0060 inches and 0.0095 inches.

### Claim 7 (depends on 5)

The liner of claim 5, the liner having a thickness greater than or equal to 0.0060 inches and less than or equal to 0.0120 inches.
