Envelope with impermanent closure

Abstract

Abstract AN ENVELOPE HAVING A PRESSURE-SENSITIVE TAPE-TYPE IMPERMANENT CLOSURE CONSISTING OF THREE TAPE STRIPS. EACH TAPE STRIP HAS AN AGGRESSIVELY ADHESIVE SIDE AND A LOW ADHESION SIDE. A FIRST AND A THIRD OF SAID TAPE STRIPS ARE ADHERED BY THEIR AGGRESSIVELY PRESSURE-SENSITIVE ADHESIVE SIDES TO THE REAR SURFACE OF THE ENVELOPE BODY IN ALIGNMENT. THE FIRST OF THE TAPE STRIPS IS LOCATED UNDER THE FLAP WHEN THE FLAP IS CLOSED AND RUNS PERPENDICULAR TO THE HINGE CONNECTING THE FLAP TO THE ENVELOPE BODY, TERMINATING AT THE POSITION OCCUPIED BY THE FREE EDGE OF THE FLAP WHEN THE FLAP IS CLOSED. THE THIRD OF THE TAPE STRIPS IS LOCATED ON THE REAR SURFACE OF THE ENVELOPE BODY AND EXTENDS AWAY FROM THE EDGE OF THE FIRST STRIP REMOTE FROM THE FLAP HINGE. THE THIRD TAPE STRIP HAS A PORTION EXTENDING FROM REMOTE EDGE OF THE FIRST STRIP. THIS PORTION IS NOT ADHESIVELY SECURED TO THE BACK OF THE ENVELOPE BODY AND IS REFFERED TO AS THE FREE PORTION. WHEN THE ENVELOPE IS SOLD THE FREE PORTION OF THE THIRD TAPE STRIP IS ADHESIVELY SECURED TO THE LOW ADHESION SIDE OF THE FIRST STRIP. A SECOND TAPE STRIP WHICH HAS ITS AGGRESSIVELY PRES- SURE-SENSITIVE ADHESIVE SIDE ADHERED TO THE BACK OF THE FLAP IS PROVIDED. THE SECOND STRIP IS IN ALIGNMENT WITH THE SAID FIRST AND THIRD TAPE STRIPS AND MAY BE SLIGHTLY WIDER. IN USE THE FREE PORTION OF THE THIRD TAPE STRIP IS PEELED FROM THE LOW ADHESION SIDE OF THE FIRST STRIP, THEN THE FLAP IS FOLDED TO CLOSED POSITION AND FINALLY THE FREE PORTION IS ADHERED TO THE LOW ADHESION SIDE OF THE SECOND STRIP FROM WHICH IT CAN BE READILY PEELED AT ANY TIME THAT THE CONTENTS OF THE ENVELOPE ARE TO BE INSPECTED. THE TIP OF THE FREE PORTION HAS A PULL TAB THEREON NEITHER SIDE OF WHICH HAS A PRESSURE-SENSITIVE ADHESIVE THEREON.
