Definitions

  • the present invention relates generally to foldmg cartons and more particularly to a novel locking means for fastening together overlying sheet material.
  • the novel locking means finds exceptional utility in the construction of folding cartons.
  • the principal object of the present invention is the provision of a novel arrangement for fastening together flexible sheet material arranged in face to face relation.
  • Another object of the present invention is the provision of an improved carton which includes such novel locking means to maintain the carton in erected condition.
  • Still another object of the present invention is to provide an improved folding carton which includes a novel arrangement for locking the panels thereof in position and for securing the cover in closed relation to the carton to thereby present a sturdy, neat package which may be directly marketed to the consumer or may be subsequently repackaged as desired.
  • a further object of the present invention is the provision of a folding carton of the type described which may be readily set up immediately prior to use and which is of strong and durable construction to withstand a substant-ial amount of rough handling and yet is of simple andeconomical manufacture.
  • FIGURE 1 is-a plan view of a blank from which a carton, embodying various features of the present invention, may be formed;
  • FIGURE 2 is a perspective view of a carton erected from the blank shown in FIGURE 1, with one of the corners shown unfastened in order to more clearly illustrate the locking means employed;
  • FIGURE 3 is a plan view of a blank from which a modified form of a carton, embodying various features of the present invention, may be erected;
  • FIGURE 4 is a perspective view of a carton erected from the blank shown in FIGURE 3, with a portion broken away and with one of the corners shown unfastened in order to illustrate the locking arrangement therefor.
  • a pair of overlapping sheets of flexible material may be elfectively secured together by a simple and novel locking arrangement.
  • the locking structure comprises generally apair of spaced-apart, generally parallel slits or cuts in one of the sheets, and a tab extending from the other sheet having a portion thereof with a width greater than the Ice distance between the slits.
  • the tab is disposed in locked engagement with the first sheet by projecting the side marginal regions thereof through the slits and into adjoining relation with the marginal areas adjacent the slits on the exposed surface of the first sheet.
  • the parallel slits are provided with a cross slit to form a cut of generally H-shape. The cross cut permits greater ease in insertion of the margins of the tab through the slits and also provides for a covering flap to close any gap formed by the insertion of the tab.
  • the improved locking arrangement of the present invention may be advantageously employed in a wide variety of structures. However, distinct advantages are achieved by utilization of the features of the improved locking arrangement in folding cartons, and more particularly in a leak-proof folded carton, such as shown in FIGURE 2, which has particular advantageous application in the packaging of frozen foods.
  • the carton 11, shown generally in FIGURE 2, is formed from the blank 13 illustrated in FIGURE 1.
  • the various walls of the carton and the panels of the blank from which the walls are formed are referred to with identical reference numbers.
  • the paperboard employed is of the water-proof type.
  • suitable paperboards are presently available for this purpose, and it will be further understood that paperboard now or hereafter available may be employed.

  • a flap 45 is joined to the outer edge of the front side wall panel 17 along a suitable scoreline 47.
  • a corner member or gusset located adjacent each of the corners of the bottom panel 15 is a corner member or gusset indicated at 49, 51, 53 and 55, respectively, which is integrally and foldably connected to the ends of the adjacent end and side wall panels through respective extensions 21a, 23a, 29a and 31a of the fold lines 21, 23, 29 and 31.
  • a score or fold line 57 extends generally diagonally of each of the gussets from the gusset corner adjacent the bottom panel to adjacentthe opposed gusset corner.
  • Each of the gussets is formed with a tab 59 for interlocking action with an adjoining carton panel.
  • the tabs 59 extend generally outward of the gusset edges which are in general alignment with the outer edge of the adjacent end wall panel 25 or 27 and are hingedly connected to said gussets along suitable fold lines 61.
  • the flap 45 and the cover panel 33 are formed with suitable tab receiving and locking means for fastening the gussets to the carton walls to maintain the carton in erected condition.
  • the preferred construction illustrated includes a pair of H-shaped slit formations 63 in both the flap 45 and cover panel 33.
  • Each of the H-shaped slit formations 63 is generally identical, and includes a pair of parallel cut lines 65 and 67, which are interconnected by a perpendicular cross cut line 69.
  • the parallel cutlines 65 and 67 extend in generally perpendicular re-- Y lation from the adjacent associated fold lines 35 or 47.
  • Each of the tabs 59 which are interlocked with the H-shaped slit formations 63 to maintain the carton erect is formed with a neck defined by the score line 61 having a width approximating the width between the parallel cut lines.
  • the sides of the tab extend in divergent angular relation outwardly from the neck and then parallel to each other to thereby form a generally rectangular tab having a width greater than the width between the parallel cut lines 65 and 67 and a height greater than the height ofthe lower displaceable portion 71 but not greater than the overall height of the parallel cut lines 65 and 67.
  • tab interlocking with a panel having, a displaceable flap'formed in part bya pair ofparallel cuts which extend from a base fold line and may be-formed at their other end in any suitable configuration.
  • the size of the tab should be proportioned-so asto-be displaceable cut lines eXtending in perpendicular relation from a fold line,'it should beunderstoodthat the presence and utilizationot such a. fold line is not necessarily essential to the presentinvention, butrepresents a preferred form thereof inorder to facilitate displacementof the adjacent lower'flap.
  • a cover panel locking't-ab or tuck 77 isfoldably connected-alongafold line 79-to the outeredge of the cover panel 33;
  • the tuck 77' may be of any-suitable shape, and as shown, is of generally rectangularform having; two converging sides;
  • the fold line 79 joining the locking tuck 77 to the-cover panel-33 is-spacedslightly inwardly of andparallel to the outer edge of thev cover panel'33-and has at each end thereofanotch-or slit 81which includes acurvednortionextendingv into alignment with the outer edge" of the cover panel and'whi'oh' forms anea'r 83 on the locking tuck adjacent each of the ends of the. fold line 7-9.
  • a slit 85 which; incident t'o'the subsequent'inward foldingof the flap 45; forms a slot or opening:87' for receiving and locking the cover panel tuck 7 7.
  • thecenterportion of-thefold line 47 joining theflap45 tome-front side-panel 17 is interrupted by the-slit 85: which joins the innerv ends: thereof;
  • the slit includes a segment 87 at each end thereof in alignment with the fold line 47, curved portions 89 which extend inward of the flap 45 from each of the segments 87, and a central segment 91 which joins the curved portions 89 and is generally parallel to the fold line 47.
  • the length of the central segment 91 is approximately equal to the length of the outer edgeinoluded between the converging sides of the cover panel locking tuck 77'.
  • the carton iserected by upward folding of the opposed side and end walls along the respective score lines joining the wall panels to the bottom panel; As the four wall panels are formed in upright condition, the gussets, as shown in FIGURE 2, are folded upon themselves along the fold line 57 and are extended outwardly of the adjacent side and end walls, being folded along the appropriate" fold line extensions.
  • the gussets may, of course, be folded overeither' the side or end walls, or may be folded inwardly of the carton and then into adjacent relation with either of the side or end walls to lock the carton in upright condition- In the carton and thereby provide leak-proof features; 11 illustrated in'FIGURE 2, the gussets 49 and 51, adjacent the front side wall 17 are'fol dedinoverlying'rela tion to thetop and side marginal portions of the front side wall to placethe tabs 59 in overlying relation to the associated slit formations63 in the flap'45.
  • the upper displaceable'portion' 73' of the slit formation 63* isfi'rst inwardly directed during insertion of the tab 59, the'pas'sage' of the outer edge of the tab clears. the bottom edge of the upper displaceable portion and allows the portion-73' to return to its originalp'osition in generally co-planar relation with the surrounding" flap panel. At the same time, the lower displaceable portion 71" urges the tab 59 into adjoining underlying.
  • Inward folding of the flap 45 also results in the formation of the slot 87 between the central segment of the :slit 85 and the front side wall 17. Accordingly, when the cover panel is folded downwardly over the carton, the locking tuck 77 may alsobe folded inwardly along :the foldline 79 and located with its outer edge in the slot 87 formed by the inward folding of the flap 45. Downward pressure on the cover panel causes the convergentside edges of the cover tuck 77 to be cammed by the curved portions 89of the flap slit into the extending segments ,87 which are in alignment with the fold line 47. When the tab is fully inserted within the slit 85, the ears 8 3 of the locking tuck snap under the flap 45 into locking engagement.
