ABSTRACT:
A rhomboid piece of paper and plastic laminate has a central rhomboid region scored with parallel lines of weakening. Border regions are provided with appropriate layers of adhesive such that when the blank is wrapped around a needle cap, the border region nearest the open end of the cap bonds to the cap and provides a first circumferentially continuous end band, while the border region nearest the closed end of the cap provides a second end band which is axially moveable relative to the cap. The two end bands are joined by a plurality of longitudinally extending circumferentailly contiguous regions which separate into strips which project radially to form an umbrella-like structure when the second end band is urged toward the first end band. The strips extend along a slight helix angle before formation of the umbrella-like structure. For increased protection a second blank having a reversed rhomboid shape but being otherwise generally similar to the first blank can either be wrapped around the tube produced by the first blank, or joined to the first blank and wrapped simultaneously.
