Grip enhancements for tabbed seal
Various enhancements of tabbed seals are provided herein with enhanced grasping functionality. Such enhancements include an anti-slip coating, a polymer adhesive layer, embossing, increasing the thickness of the tab, and/or increasing the overall surface area of the tab.
1. A tabbed sealing member for sealing to a rim surrounding a container opening, the sealing member comprising:
a multi-layer laminate including an upper laminate portion partially bonded to a lower laminate portion forming a gripping tab defined wholly within a perimeter of the sealing member, the gripping tab for removing the sealing member from the container opening;
the lower laminate portion positioned below the gripping tab and including at least a sealant layer for bonding to the container rim;
the upper laminate portion including a plurality of layers, one of the layers being an embossed layer and one of the layers being a non-embossed layer, the embossed layer imparting a texture having a repeating pattern to just a gripping tab portion of the non-embossed layer when combined to form the upper laminate portion.
2. The tabbed sealing member of claim 1 , wherein the embossed layer is at least one of a polymer foam layer and a non-foam polymer layer.
3. The tabbed sealing member of claim 1 , wherein the embossed layer is an internal layer of the upper laminate and provides the repeating pattern of raised protrusions on an exposed external surface of the upper laminate.
4. The tabbed sealing member of claim 3 , wherein the raised protrusions make up approximately 25-75% of the exposed external surface of the upper laminate.
5. A method of forming a tabbed sealing member for sealing to a rim surrounding a container opening, the method comprising:
providing an embossed layer;
providing a non-embossed layer;
combining the embossed layer with the non-embossed layer to form an upper laminate portion, the embossed layer imparting a texture to just a gripping tab portion of the non-embossed layer such that at least one of an upper and a lower surface of the upper laminate portion has an increased texture compared to the non-embossed layer prior to combination with the embossed layer, the texture having a repeating pattern; and
combining the upper laminate portion with a lower laminate portion to form the tabbed sealing layer whereby the upper laminate portion partially is bonded to the lower laminate portion forming a gripping tab defined wholly within a perimeter of the sealing member, the gripping tab for removing the sealing member from the container opening.
6. The method of claim 5 , wherein the embossed layer is at least one of a polymer foam layer and a non-foam polymer layer.
7. The method of claim 5 , wherein the embossed layer is an internal layer of the upper laminate and provides the repeating pattern of raised protrusions on an exposed portion of at least one of the upper and lower surfaces of the upper laminate.
8. The method of claim 7 , wherein the raised protrusions make up approximately 25-75% of the exposed portion.
9. A tabbed sealing member for sealing to a rim surrounding a container opening, the sealing member comprising:
a multi-layer laminate including an upper laminate portion partially bonded to a lower laminate portion forming a gripping tab defined wholly within a perimeter of the sealing member, the gripping tab for removing the sealing member from the container opening;
the lower laminate portion positioned below the gripping tab and including at least a sealant layer for bonding to the container rim;
the upper laminate portion including a support layer, a tab layer, and a thickening layer, the thickening layer being a partial layer positioned at an outer edge of the upper laminate to provide a thickened portion relative to a thinner inward portion of the upper laminate,
wherein the thickening layer at least doubles the thickness of the outer edge of the upper laminate compared to an upper laminate that does not include the thickening layer.
10. The sealing member of claim 9 , wherein the thickening layer is at least as thick as the thinner inward portion of the upper laminate.
11. The sealing member of claim 9 , further comprising a second thickening layer positioned inwardly of the outer edge wherein the thinner inward portion is between the thickening layer and the second thickening layer.
12. The sealing member of claim 9 , wherein the thickening layer is positioned between the support layer and the tab layer.
13. The sealing member of claim 9 , wherein the thickening layer is positioned on an outer surface of the tab layer.
