Removable adhesive tape
First Claim
1. An assembly comprising a container including first and second relatively moveable panels positioned in a closely adjacent closed position to close the container, and being moveable to an open position with said relatively moveable panels spaced apart to open said container, said relatively moveable panels including attached portions having surfaces that are closely adjacent in said closed position;
- anda tape sealing said relatively movable panels in said closed position, said tape being highly extensible, having first and second opposite tape surfaces, and sealing means for attaching the first tape surface to the surface of the attached portion on the first panel and comprising a layer of pressure sensitive adhesive defining the second tape surface for adhering the tape to the surface of the attached portion of said second panel to thereby retain the relatively moveable panels in said closed position, said tape being highly extensible and removable from said attached portions by stretching said tape to at least about 150% of its initial length at an angle no greater than about 35°
from the surfaces of said attached portions, said tape including a tab portion projecting past at least one of said relatively moveable panels and adapted for manual engagement to afford manual stretching of said tape.

Abstract
A removable adhesive tape comprising a highly extensible and substantially inelastic backing and a layer of pressure-sensitive adhesive. The backing has a high tensile strength, has a lengthwise elongation at break of at least about 150% with less than about 50% elastic recovery after stretching. The adhesive can be a normally tacky and pressure-sensitive adhesive and is coated on at least one surface of the film backing. The adhesive is preferably highly extensible, does not separate from the backing during stretching, and has higher cohesion than adhesion to any suitable substrate. After being applied to a substrate, the adhesive tape of the present invention becomes firmly bonded, but can be easily removed without damaging the substrate by simply stretching it in a direction substantially parallel, i.e. less than about 35°, to the surface of the substrate.
