Multi-panel sterilization assembly with transport adhesive
View Patent ↗The multi-panel sterilization assembly includes a barrier panel formed of permeable material having barrier properties, side wings that can include grip portions for folding or unfolding the barrier panel; and a fold protection panel. The assembly has at least one pull tab attached to an end of the barrier panel to aid in unfolding the assembly after sterilization. At least one wing and/or pull tab is held in place against the barrier panel during manufacturing with a transient adhesive that loses strength such that the wing or pull tab is easily pulled off the barrier panel after sterilization.
1. A flexible multi-panel sterilization assembly comprising a barrier panel having a first end defining a fold protection panel, a second end, opposing first and third edges, a second edge opposite the first end, opposing first and second wings, wherein the first wing, the second wing, or both include panel attachment means to secure portions of the first edge and the third edge to each other or to a portion of the second end after the barrier panel has been folded at or near its midpoint such that its second end is brought towards its first end, and at least one pull tab attached to the second end used to unfold the barrier panel, wherein the pull tab is held against said assembly with a only transient adhesive that loses strength over time, wherein the transient adhesive holds the pull tab against said assembly with a force of at least about 150 grams force tensile pull during manufacturing of the sterilization assembly, wherein the transient adhesive holds the pull tab against said assembly with a force of less than 150 grams force tensile pull after sterilization of the assembly, wherein the barrier panel includes a first surface configured to cover or contact an item to be sterilized and an opposing second surface, wherein the transient adhesive prevents movement of the pull tab during manufacturing yet allows the pull tab to move freely after manufacturing, wherein movement of the pull tab during manufacturing is prevented utilizing attachment means consisting of the transient adhesive.
2. The sterilization assembly of claim 1 , wherein the wings are located on the second surface of the barrier panel.
3. The sterilization assembly of claim 1 , wherein the panel attachment means comprise adhesive tape, double-sided adhesive tape, cohesive materials, hook and loop fastening systems, mechanical fastening systems, snaps, clips, magnets, catches, slots and tabs, and combinations thereof.
4. The sterilization assembly of claim 1 , wherein the sterilization assembly includes two pull tabs and two spaced apart pull locations.
5. The sterilization assembly of claim 1 , wherein the at least one pull tab is positioned to be accessible during unfolding or unwrapping the item after sterilization.
6. The sterilization assembly of claim 5 , wherein the pull tab extends from or is joined to the second end of the barrier panel.
7. The sterilization assembly of claim 5 , wherein the pull tab extends from or is joined to the second end of the barrier panel at the opposing second surface.
8. The sterilization assembly of claim 1 , wherein a distal end of the at least one pull tab is secured to the second end of the barrier panel with the transient adhesive.
9. The sterilization assembly of claim 1 , wherein the transient adhesive is a hot melt adhesive.
