Claims
- 1. The method of taping a case made of paper-board or the like having sides, ends and top and bottom closures, at least one of said closures comprising two flaps folded over from the sides of the case, said flaps being generally coplanar and having adjoining edges extending generally parallel to one another endwise of the case, said method comprising pressing a strip of tape having pressure-sensitive adhesive on one face thereof to extend from end-to-end of the case throughout the length of the said flaps over the margins of said flaps along said adjoining edges, and adhering the tape by said adhesive to said margins to seal the case along said adjoining edges, providing portions of the tape extending around on the outside of the ends of the case and part way between the top and bottom of the case, folding back an integral end portion of at least one of said portions on the adhesive face of the tape, pressing said portions of the tape against the ends of the case to cause them to become adhered to the ends of the case except for said folded-back end portion, the latter being adhered in its folded-back relation to the tape by said adhesive and lying between said one portion of the tape and the respective end of the case to form a tab at the end of said one portion of the tape which tab is unadhered to the respective end of the case, the adhesive peelably securing the tape to the margins of the flaps and the ends of the case, said tab being free to be grasped and pulled to peel the tape away from said respective end of the case and then lengthwise completely away from the margins of said flaps to free the flaps for opening the case, wherein the tape is applied from one end of the case to the other and the folding back of said integral end portion of the tape is completed as the tape is applied.
- 2. The method of taping a case made of paper-board or the like having sides, ends and top and bottom closures, at least one of said closures comprising two flaps folded over from the sides of the case, said flaps being generally coplanar and having adjoining edges extending generally parallel to one another endwise of the case, said method comprising pressing a strip of tape having pressure-sensitive adhesive on one face thereof to extend from end-to-end of the case throughout the length of the said flaps over the margins of said flaps along said adjoining edges, and adhering the tape by said adhesive to said margins to seal the case along said adjoining edges, providing portions of the tape extending around on the outside of the ends of the case and part way between the top and bottom of the case, folding back an integral end portion of at least one of said portions on the adhesive face of the tape, pressing said portions of the tape against the ends of the case to cause them to become adhered to the ends of the case except for said folded-back end portion, the latter being adhered in its folded-back relation to the tape by said adhesive and lying between said one portion of the tape and the respective end of the case to form a tab at the end of said one portion of the tape which tab is unadhered to the respective end of the case, the adhesive peelably securing the tape to the margins of the flaps and the ends of the case, said tab being free to be grasped and pulled to peel the tape away from said respective end of the case and then lengthwise completely away from the margins of said flaps to free the flaps for opening the case, wherein the folding back of said integral end portion of the tape is completed at said one end of the case as the tape is applied.
- 3. Apparatus for taping a case made of paper-board or the like having sides, ends and top and bottom closures, at least one of said closures comprising two flaps folded over from the sides of the case, said laps being generally coplanar and having adjoining edges extending generally parallel to one another endwise of the case, said apparatus comprising means for pressing a strip of tape having pressure-sensitive adhesive on one face thereof to extend from end-to-end of the case throughout the length of the said flaps over the margins of said flaps along said adjoining edges and adhering the tape by said adhesive to said margins to seal the case along said adjoining edges and for pressing portions of the tape extending around on the outside of the ends of the case and part way between the top and bottom of the case and adhering said portions by the adhesive to the outside of the ends of the case, and means for folding back an integral end portion of at least one of said portions on the adhesive face of the tape and adhering it in its folded-back relation to the tape by said adhesive, said integral end portion lying between said one portion of the tape and the respective end of the case to form a tab at the end of said one portion of the tape which tab is unadhered to the respective end of the case, the adhesive peelably securing the tape to the margins of the flaps and the ends of the case, said tab being free to be grasped and pulled to peel the tape away from said respective end of the case and then lengthwise completely away from the margins of said flaps to free the flaps for opening the case.
- 4. Apparatus as set forth in claim 3 wherein the means for pressing the strip of tape is operable to apply the tape from one end of the case to the other, and the folding back of said integral end portion of the tape is completed as the tape is applied.
- 5. Apparatus as set forth in claim 4 wherein the means for folding back said integral end portion of the tape is operable at said one end of the case.
