An easy access tear-open paperboard package and method of making same are provided including a pair of corrugated paperboard sheets, each having an interior surface flood coated with a cohesive material which sheets are then joined together in surrounding relation to an article such as a book contained therebetween. A strip of polyolefin tape extends across the interior surface of at least one of the corrugated paperboard sheets to provide a non-bonding area. A pair of spaced parallel perforations extend through paperboard sheet and the tape to form a tear strip which is narrower in width than the tape to provide access to the interior compartment.

[ I claim:] [1.] A blank for forming an improved access, tear-open corrugated paperboard package comprising:a sheet of paperboard having a first surface and a second surface; a cohesive coating over substantially the entire first surface of said sheet; a portion of said first surface having a covering strip having opposed longitudinal sides thereon, said covering strip having a bottom surface which is bonded to the cohesive coating on said first surface of said paperboard sheet, said covering strip having a top surface which does not adhere to said cohesive coating; and, at least one pair of spaced parallel perforations extending into said sheet and said covering strip between the longitudinal sides thereof to define a tear strip in said blank. [9.] An improved access, tear-open paperboard package for containing an article, said package comprising:a first sheet of paperboard; a second sheet of paperboard; an article contained between said first and second paperboard sheets; said first and second sheets having interior surfaces which are in face-to-face relationship with each other, said interior surfaces of said first and second sheets each having a coating thereon which enables them to adhesively bond to each other which coating does not adhesively bond to said article contained within said package; said top and bottom sheets being adhered to each other in generally surrounding relationship to said article contained within said package; a covering strip over a portion of the interior surface of at least one of said first and second sheets, said covering strip having a bottom surface which is adhesively bonded to the interior surface of said at least one sheet, said covering strip having a top surface which does not adhesively bond to the coating on the interior surfaces of said first and second sheets; and, a tear strip formed in at least one of said first and second sheets and positioned in underlying relationship to said covering strip, said tear strip being narrower than said covering strip and being defined by perforations which extend into said at least one sheet and the covering strip, said tear strip being positioned so that when it is severed from said at least one sheet access to the interior of said package for removal of the article therefrom is provided. The package of claim 9 wherein said first and second sheets are separately formed. The package of claim 9 wherein said first and second paperboard sheets are formed from a single sheet which is folded so that one surface thereof forms said interior surfaces of said first and second sheets and the other surface thereof forms the exterior surface of said first and second sheets. The package of claim 9, wherein said first and second paperboard sheets comprise single face corrugated paperboard. The package of claim 9, wherein the interior surface of each of said first and second paperboard sheets is corrugated. The package of claim 9, wherein said coating includes a layer of cohesive material disposed over substantially the entire interior surface of each of said first and second paperboard sheets. The package of claim 9, wherein the bottom surface of said covering strip has a cohesive coating. The package of claim 9, wherein said covering strip comprises polyolefin tape. The package of claim 16, wherein said polyolefin tape extends from one edge of said one of said first and second sheets to another edge of said one sheet.
