Claims
- 1. A method for forming a tactile surface on a pair of tabs of a formed flexible liner, wherein said pair of tabs includes a first tab and a second tab, said first tab having a first side and a second side wherein said second side is opposite said first side, said second tab having a third side and a fourth side wherein said fourth side is opposite said third side, said method comprising the steps of:
- positioning a first tool so that a plurality of teeth of said first tool is directed toward a receiving surface of a second tool;
- situating the tabs of the flexible liner between said plurality of teeth and said receiving surface;
- moving at least one or both of said first tool and said second tool towards the other tool;
- piercing a particular percentage of said plurality of teeth through the pair of tabs from said first side through said second side, said third side, and said fourth side of the pair of tabs, with sufficient force so that said teeth just contacts said receiving surface, thereby forming a plurality of pierced holes through the pair of tabs; and
- drawing said plurality of teeth away from said receiving surface, leaving a tactile surface on said second side and said fourth side of each pair of tabs and a non-tactile surface on said first side and said third side of each pair of tabs.
- 2. The method of claim 1 wherein said particular percentage is about 50% of said plurality of teeth.
- 3. The method of claim 1, wherein said tactile surface includes a plurality of ruptured protuberances and a plurality of non-ruptured protuberances.
- 4. The method of claim 3, wherein said plurality of ruptured protuberances are formed by said particular percentage of plurality of teeth which pierce through said pair of tabs.
- 5. The method of claim 3, wherein said plurality of non-ruptured protuberances are formed by a percentage of said plurality of teeth which do not pierce through said pair of tabs.
- 6. The method of claim 1, wherein said tactile surface is formed on an outer portion of said second side of said first tab and an outer portion of said fourth side of said second tab.
- 7. A method for forming a textured surface on a tab of a formed flexible liner, wherein said tab has a first side and a second side, said second side being opposite said first side, said method comprising the steps of:
- disposing said tab between a first tool and a second tool, wherein said first tool has a plurality of teeth and said second tool has a receiving surface;
- pressing said first tool and said second tool together so as to form a sandwich with said tab positioned therein, whereby said first side of said tab engages said plurality of teeth and said second side of said tab engages said second tool;
- piercing a particular percentage of said plurality of teeth through said tab from said first side through said second side, with sufficient force so that said plurality of teeth form a plurality of ruptures through said tab; and
- separating said first tool and said second tool, thereby forming a textured surface on said second side of said tab.
- 8. The method of claim 7, wherein said textured surface includes a plurality of ruptured protuberances and a plurality of non-ruptured protuberances.
- 9. The method of claim 8, wherein said plurality of teeth includes a plurality of dull teeth and a plurality of piercing teeth, whereby said dull teeth form said non-ruptured protuberances and said plurality of piercing teeth form said ruptured protuberances of said textured surface.
- 10. The method of claim 9, wherein said plurality of piercing teeth comprises at least 50% of said teeth of said first tool, whereby at least 50% of said textured surface includes said ruptured protuberances.
- 11. The method of claim 7, wherein two tabs are disposed between said first tool and said second tool, thereby forming a textured surface on one side of each tab.
- 12. The method of claim 7, wherein said textured surface is formed on an outer portion of said tab.
- 13. The method of claim 7, wherein said textured surface includes a first textured area and a second textured area.
- 14. The method of claim 13, wherein said first textured area and said second textured area are substantially similar.
- 15. The method of claim 13, wherein said first textured area is spaced apart from said second textured area by a smooth surface located in-between and adjacent to said first textured area and said second textured area.
- 16. The method of claim 7, wherein said plurality of teeth are located on said first tool at intervals of from about 0.015 inches to 0.250 inches.
