Abstract
A tape closure system is shown and described herein. The tape closure system includes a first tape component having a pressure sensitive adhesive and a second tape component having a pressure sensitive adhesive, where at least one of the pressure sensitive adhesives has a modified surface to reduce the tack of the surface such that when the first and second pressure adhesives are brought into contact with one another they may sufficiently adhere to one another to form a seal but are still separable from one another and able to be repeatedly opened and sealed.
Claims26
An adhesive closure system comprising:
- a first pressure sensitive adhesive layer having an upper adhesive surface;
- a second pressure sensitive adhesive layer having an upper adhesive surface;
- wherein the upper adhesive surfaces of the first and second pressure sensitive adhesive layers are releasably securable to one another to form a closure, and the upper adhesive surface of (i) the first pressure sensitive adhesive layer, (ii) the second pressure sensitive adhesive layer, or (iii) both the first pressure sensitive adhesive and the second pressure sensitive adhesive layers comprises a plurality of filaments and/or ellipsoids defining a modified surface topography;
- wherein the filaments and/or the ellipsoids are of different shapes, lengths and/or thicknesses disposed in a random distribution on top of the upper adhesive surface of at least one pressure sensitive adhesive layer, and at least two of the plurality of filaments and/or ellipsoids on a given adhesive layer partially overlap with one another;
- wherein the filaments and/or the ellipsoids are formed by materials applied on the upper adhesive surface of at least one pressure sensitive adhesive layers;
- and
- wherein the filaments and/or the ellipsoids are not ordered and comprise sprayed, printed, sprinkled, dusted and/or brushed materials applied onto the upper adhesive surface to provide randomized distribution of the filaments and/or the ellipsoids on the upper adhesive surface.
An article having a first surface and a second surface adapted to be releasably joined together, the article comprising an adhesive closure system comprising:
- a first pressure sensitive adhesive layer having an upper adhesive surface disposed on the first surface;
- and
- a second pressure sensitive adhesive layer having an upper adhesive surface disposed on the second surface, wherein the upper adhesive surfaces of the first and second pressure sensitive adhesives layers are releasably adherable to one another, and the upper adhesive surface of (i) the first pressure sensitive adhesive layer, (ii) the second pressure sensitive adhesive layer, or (iii) both the first pressure sensitive adhesive and the second pressure sensitive adhesive layers comprises a plurality of filaments and/or ellipsoids defining a modified surface topography;
- wherein the filaments and/or the ellipsoids are of different shapes, lengths and/or thicknesses disposed in a random distribution on top of the upper adhesive surface of at least one pressure sensitive adhesive layer, and at least two of the plurality of filaments on a given adhesive layer partially overlap with one another;
- wherein the filaments and/or the ellipsoids are formed by materials applied on the upper adhesive surfaces of at least one pressure sensitive adhesive layers, and
- wherein the filaments and/or the ellipsoids are not ordered and comprise sprayed, printed, sprinkled, dusted and/or brushed materials applied onto the upper adhesive surface to provide randomized distribution of the filaments and/or the ellipsoids on the upper adhesive surface.
