Definitions

  • This invention relates to easy-open case taping, more particularly to a case sealed by a tape with an easy-open feature, and a method of and apparatus for taping a case with the tape having the easy-open feature.
  • the invention is especially concerned with the taping of a case made of paperboard or the like having a closure (e.g. a top) comprising two folded-over flaps, such as two side flaps folded over from the sides of the case on end flaps folded in from the ends of the case, and having adjoining parallel edges extending generally along the center line of the closure.
  • a closure e.g. a top
  • two folded-over flaps such as two side flaps folded over from the sides of the case on end flaps folded in from the ends of the case, and having adjoining parallel edges extending generally along the center line of the closure.
  • closures have been conventionally completed by applying an adhesive tape to the margins of the two side flaps along said edges, the tape extending throughout the length of said closure of the case and part way along the ends of the case, being adhered to the side flaps and the ends of the case completely throughout its length. Removal of the tape for opening up the side flaps to open the case has been difficult, if not impossible, and generally the case is opened by s
  • the object of this invention is to provide a case having a strip of tape adhered to the margins of the side flaps along the edges of the side flaps but with the tape having an easy-open feature whereby an end of the tape may be readily grasped and pulled to peel the tape away from the case for opening it, thereby eliminating the need for slitting the tape.
  • the easy-open feature involves the provision of a tab at one end of the tape formed by folding back an end portion of the tape on the adhesive face of the tape and adhering the folded-back portion to the tape, the tab being unadhered to the case for being grasped and pulled to peel the tape away from the case.
  • a case made of paperboard or the like, e.g. corrugated box board, having a top 3, bottom 5, sides each designated 7 and ends each designated 9.
  • the top 3 is illustrated as a top closure such as is conventionally formed, after the case has been packed, by folding two end flaps each designated 11 over from the top of the case ends 9 on top of product packed in the case, and then folding over two side flaps each designated 13 from the top of the case sides 7 on top of the end flaps.
  • the side flaps 13, when completely folded over, are generally coplanar and have adjoining parallel edg es each designated 15 which may be generally in abutting relation or closely adjacent relation.
  • the flaps 13 are secured together along said edges 15 by a strip of tape 17, more particularly a strip of pressure-sensitive tape of a type conventionally used for taping cases, having pressure-sensitive adhesive on one face A thereof by means of which the strip of tape is adhered to the margins of the flaps 13 along said edges 15.
  • the strip of tape extends throughout the length of the top 3 of the case, and has portions 19 extending down on the outside of the ends 9 of the case for some distance.
  • the bottom closure 5 generally also comprise end flaps and side flaps, like the top closure, these flaps being secure in suitable manner. They may be taped, like the top closure.
  • the tape has at least at one end thereof, i.e. at the lower end of one of the downwardly extending portions 19, an integral end portion 21 folded over on a line 23 extending across the tape from one side thereof to the other and generally at right angles to the side edges of the tape, with the adhesive on said folded-over end portion 21 on the inside of said end portion 21 and with said end portion 21 flattened and adhered by the adhesive to the tape to form a tab indicated at 25 at said one end of the tape which is unadhered to the end of the case and thus free of the end of the case for being grasped and pulled to peel the tape throughout its length away from the flaps 13 of the case.
  • the tab 25 for grasping the tape and peeling it away from the case is formed during the operation of applying the tape to the case as illustrated in Figs. 10-13.
  • a continuous length of tape T having the adhesive A on said one face thereof is fed forward (down) from a supply, more particularly a roll 27 of the tape, and applied to a case 1 as the case if fed forward (toward the left as viewed in Figs. 10-13) endwise along a horizontal path by a case conveyor 29, the tape being adhered by the said adhesive first to a portion of the leading end 9 and then to the margins of the flaps 13 along the edges 15 of the flaps.
  • the continuous length of tape is severed to supply the strip 17 of sufficient length to provide for end portions 19 of the tape extending down on the ends 9 of the case.
  • the integral end portion 21 of the tape is bent up and the bent-up end portion 21 is adhered by the adhesive on the tape to the tape to form the tab 25.
  • the tape T is guided to extend down from the supply roll 27 with the tape at its lower end extending down into the path of a case 1 being fed forward in the stated horizontal path by the conveyor 29, and with the adhesive face A of the tape facing the oncoming leading end 9 of the case.
  • the conveyor 29 is operable to feed a case 1 to be taped forward under a taping head indicated generally at 31.
  • the taping head which is suitably fixed in position above the conveyor at a taping station along the length of the conveyor, applies pressure-sensitive adhesive tape issuing from the tape supply roll 27, which is suitably mounted above the head, to the case as the case is fed forward under the head.
  • the head comprises a frame including a pair of side plates each designated 33.
  • a first presser means comprising a roller 35 is provided for pressing the tape against the leading end of a case 1 and then down on the top 3 of the case over the length of the case as the case is fed forward on the conveyor 29 under the taping head 31.
  • a knife for cutting the tape.
  • a second presser means comprising a roller 39 is provided for continuing the pressing of the tape, down on the top of the case over the length of the tape, and, after the tape has been cut by the knife, against the trailing end 9 of the case.
  • Roller 35 is mounted at one end, constituting the lower end, of a two-s ided lever 41 pivoted for swinging movement on a horizontal transverse axis at 43 between the side plates 33.
  • the roller 35 is free-rolling on a pin 45 extending horizontally between the sides 47 of lever 41 at its said lower end.
  • Roller 39 is mounted at one end, constituting the lower end, of a two-sided lever 49 pivoted for swinging movement on a horizontal transverse axis at 51 between the plates 33 downstream (in relation to the travel of a case 1) from lever 41 and roller 35.
  • the roller 39 is free-rolling on a pin 53 extending horizontally between the sides 55 of lever 49 at its lower end.
  • the levers 41 and 49 are interconnected by a link 57 for conjoint movement, and are biased by a spring 59 connected to lever 49 to swing down to the lowered retracted position in which each of the rollers 35 and 39 is illustrated in solid lines in Fig. 9 wherein they are below the plates 33 and in the path of a case 1 being fed forward on the conveyor.
  • the first roller 35 is adapted to swing up with lever 41 in clockwise direction as viewed in Fig. 9 from its lowered position, and, acting through the link 57, thereupon swings the lever 49 carrying roller 39 in the opposite direction, i.e. counterclockwise, raising the roller 39 out of the path of the case.
  • spring 59 is tensioned and biases the levers to swing back down.
  • the tape T is trained to extend from the supply roll 27 down through the head frame around a guide roll 61 extending between the side plates 33 and thence around guide rolls 63 and 65 extending between the sides 47 of lever 41 to have a lower end reach indicated at 67 in Fig. 9 extending downwardly and rearwardly at the front (the upstream side) of the first presser roller 35 between the latter and the oncoming leading end 9 of a case 1 being fed forward on conveyor 29 toward roller 35.
  • the knife 37 is carried by a two-sided lever 69 pivoted for swinging movement at 43, the two sides of lever 69 being on the outside of sides 47 of lever 41 and inside side plates 33.
  • the lever 69 is biased to swing down by a spring 71 to the position shown in solid lines in Fig. 9 wherein the knife is below the plates 33, and is adapted to be swung up against the spring bias by a case 1 fed forward on conveyor 29, the spring snapping the lever back down when the case passes out of engagement with the lever, for severing of the tape by the knife.
  • the taping head as thus far described is generally the same as that of a case taping machine which has been on the market by Bemis Company, Inc. of Minneapolis, Minnesota, under the name BEMISTAPER.
  • the taping head 31 is provided with means generally designated 73 for folding up integral end portion 21 of the stated lower end reach 67 of the tape for the formation of the tab 25. As shown in Fig.
  • this means comprises a pocket-forming member 75, formed from a piece of sheet metal, generally in the shape of a J (as viewed from one side) having a straight leg 77, an arcuate foot 79 shaped in accordance with the presser roller 35, and a toe portion on the foot comprising an outwardly extending relatively narrow web 81 and a flange or lip 83 extending up from the web at its outer edge.
  • This pocket-forming member 75 has its straight leg 77 pivoted for swinging movement on a horizontal transverse axis at 85 between the sides 47 of the lever 41 above the roller 35, and is biased by a spring 87 to swing to the position in which it is illustrated in solid lines in Fig.
  • the tape folding means 73 further comprises means for forcing the tape into the pocket 89 and thereby initiating the folding thereof to form the tab, this means comprising a nozzle 91 for delivering a blast of air on the portion of the tape which extends over the pocket to blow that portion into the pocket, thereby forming a loop L of the tape in the pocket with the front side of the loop (the side away from the roller 35) constituting the stated end portion 21 of said end reach 67 of the tape bent up on the inside of the flange and extending up beyond the flange for a relatively short distance, the other side of the loop extending up on the front of the roller 35.
  • Delivery of the air blast via the nozzle is under control of a control valve 93 which in turn is under control of the presser roll mechanism by means of engagement of the lever 49 at its upper end with an actuator 95 for the valve 93.
  • This controls the supply of air under pressure from a source (not shown) to a valve 97 which, on delivery of control air thereto from valve 93, acts to deliver a shot of air from the source of air to the nozzle 91 via a line 99, the arrangement being such that on actuation of the valve 93 by the lever 49 as it returns to its home position of Fig. 9, a blast of air is delivered through the nozzle.
  • the case 1 to be taped is fed forward on the conveyor 29 toward the first presser roller 35 as illustrated in Fig. 10.
  • its leading end 9 substantially simultaneously engages both the exposed portion of the tape 21 and the top of the upturned flange 83 on the top on the arcuate foot 79 of the pocket-forming member 75, and swings the member 75 clockwise on its pivot 85 against the return bias of spring 87 so that the flange 83 is swung away from in front of the upwardly extending end portion 21 of the lower end reach 67 of the tape (see Fig. 11).
  • the leading end 9 of the case engages the bent-up end portion 21 then presses it against part of the tape immediately adjacent portion 21, thereby to squeeze together portion 21 and said adjacent part of the tape so that they become securely adhered together by the adhesive on the tape and form the tab 25 with the outside (the non-adhesive side) of portion 21 included in the tab facing the leading end of the case.
  • the leading end 9 of the case engaging the outside of the upwardly folded end portion 21 of the tape and the adhesive side of the lower end reach 67 of the tape above end portion 21 where the adhesive is exposed, pushes against the roller 35 so that the lower end reach of the tape is securely adhered to the leading end of the case.
  • the lever 41 carrying the roller 35 is swung up (clockwise) against the bias of spring 59, the roller 35 riding up the leading end of the case, and then riding on the tape on top of the case to press the tape down on top of the flaps 13.
  • lever 49 carrying roller 39 On upward swing of the lever 41 carrying roller 35, lever 49 carrying roller 39 is swung up (countercl ockwise) against the bias of spring 59 by the link 57 to the raised position shown in phantom in Fig. 9 and in dotted lines in Fig. 12 to clear the way for the travel of the case past the roller 39. Also, as the leading end 9 of the case moves on past the roller 35, it engages the lower ends of the sides of the knife lever 69 and swings this lever up against the bias of spring 71 to the raised position in which the lever is shown in phantom in Fig. 9 and in dotted lines in Fig. 12, the lever being held up in the raised position by engagement with the top of the case.
  • lever 49 activates valve 93 and so that a blast of air is delivered through nozzle 91 to tuck the tape into the pocket 89 to form the loop L, and thus the end of the tape is prepared for taping the next case.
  • Fig. 7 shows a modification wherein the end portion of the tape, here designated 21a, is folded back on a line 23a generally at a 45° angle to the edges of the tape (instead of at right angle) forming a tab designated 25a.
  • the strip of tape may have a tab such as 25 or 25a at both ends.
  • a tab such as 25 or 25a at both ends.
  • a remoistening gummed tape may be used, the gluing medium on the tape being used to form the tab.
