Abstract
The present invention relates to an adhesive closure system. More specifically, this invention relates to an adhesive closure system with an abridged release liner. Initially, the abridged release liner allows partial exposure of the single adhesive layer to achieve a temporary bond. When desired, the release liner can be removed exposing the remainder of the adhesive to achieve a permanent bond. This type of closure system has numerous applications including the closure system for pipe insulation sleeves.
Claims26
A pipe insulation sleeve assembly which comprises:
- (a) an elongated, hollow, cylindrically shaped tubular section of insulating material having a longitudinally extending access slit between an inner surface and an outer surface of said sleeve, said access slit defining a first side and a second side of said outer surface adjacent said access slit;
- (b) a closure system for maintaining said access slit in a closed position, said closure system comprising an adhesive carrier integrally secured to a first side of said outer surface, extending between said first and second sides of said outer surface and across said access slit, a layer of adhesive disposed on at least a portion of said carrier and capable of contacting said outer surface second side;
- (c) a release liner removably disposed on a first area of said adhesive layer, while a second area of said adhesive layer remains exposed;
- such that said exposed second area of adhesive layer affords an initial bond between said carrier and said outer surface second side of said access slit;
- said first and second areas of exposed adhesive layer combine to afford a second bond between said carrier and said outer surface second side of said access slit when said release liner is removed.
A pipe insulation sleeve assembly which comprises:
- (a) an elongated, hollow, cylindrically shaped tubular section of insulating material having a longitudinally extending access slit between an inner surface and an outer surface of said sleeve, said access slit defining a first and a second side wall;
- (b) a closure system comprising a layer of adhesive disposed on at least a portion of at least one side wall and having an exposed surface;
- (c) a release liner removably disposed on a first area of said exposed surface of said adhesive layer, while a second area of said adhesive layer remains exposed;
- such that said exposed second area of adhesive layer affords a first bond between said first and second side walls of said access slit;
- said first and second areas of exposed adhesive layer combine to afford a second bond between said first and second side walls when said release liner is removed.
A method for closing a pipe insulation sleeve, said insulation sleeve having an elongated, hollow, cylindrically shaped tubular section of insulating material having a longitudinally extending access slit between an inner surface and an outer surface of said sleeve, said access slit defining a first side and a second side of said outer surface adjacent said access slit;
- a closure system for maintaining said access slit in a closed position, said closure system comprising an adhesive carrier integrally secured to a first side of said outer surface, extending between said first and second sides of said outer surface and across said access slit, a layer of adhesive disposed on at least a portion of said carrier and capable of contacting said outer surface second side;
- a release liner removably disposed on a first area of said adhesive layer, while a second area of said adhesive layer remains exposed;
- comprising the steps of:
- (a) forming an initial closure of said access slit by pressing into sealing engagement said second area of said adhesive layer onto said second side outer surface;
- (b) severing said initial closure;
- (c) removing said release liner to expose said first area of said adhesive layer;
- (d) forming a second closure of said access slit by pressing into sealing engagement said first area and said second areas of said adhesive layer onto said second side outer surface.
