Definitions

  • the end flaps are articulated to the opposite sides of the bottom panel for bonding to the major end panel and with a guide tab to guide said flaps during folding.
  • a minor end panel strip overlies the free edge of the major end panel to complete the sealed carton.
  • Embossed fold beads cooperate with free edges to enhance sealing efficiency and the panel forming slits are spaced from the center line of the beads to provide further caulking of the joints.
  • Blanks are oppositely directed on the flat stock with the major and minor panels. and the guide tabs being contiguous to each other for conservation of material. Hot air nozzles are provided at a process station to activate preapplied thermoplastic material on not only the panels, but also on the fold beads.
  • the present invention relates to cartons for effective holding of liquid or semi-liquid products and the method of forming the same, and more particularly, to improvements relating to a carton wherein effective sealing for liquid tightness is accomplished with a minimum size blank.
  • a foldable carton or box utilizing a minimum size stock blank is adapted for efficient formation by machine and is liquid-tight.
  • the size of the blank for a give size carton is not only minimized, but the blank is also designed for nested cutout of multiple blanks from sheet stock with minimum wastage.
  • a minor end panel strip is folded over the free edge of full width end panel to form the side seam and to seal the remaining corner of the bottom of the carton.
  • the edge of the major end panel abuts the internal score bead formed along the panel strip to enhance the sealing of the side seam.
  • the end flap abuts the fold bead formed by the major end panel along a defined distance so that the bottom of the container is effectively leakproof.
  • the guide tab is triangular and provided immediately above the area of the hot air activated adhesive strip.
  • This guide tap is adhesive-free (not activated) and is engaged by the major end flap as the same is folded over in order to prevent the end flap from springing back or flying out of its initially folded position.
  • An adhesive strip area across the inside bottom of the end panel cooperates with the strip along the outside bottom of the end flap to form the secure, leakproof bond desired.
  • the panel strip is next plowed into final positionoverlying the free edge of the major end panel and the carton is subjected to compression (as is conventional for setting of the seals. Y
  • the sealing efficiency of the carton of the present invention is enhanced by providing specific length slits in the paperboard stock to define the panels, i.e., slits are provided that terminate approximately at the outside edge of the bead.
  • This structure induces advantageous compressing and crushing of the paperboard and the thermoplastic material along the score bead for greater caulking action.
  • the feature tends to cause a pucker of the fold bead at the corner area, which puckering of the material exactly at the corner of the package effectively and efficiently eaulks the pinholes that normally occur in other carton designs.
  • FIG. 1 is a layout view of a carton blank formed in accordance with the principles of the present invention and showing the surfaces forming the inside of the finished carton;
  • FIG. 2 is a perspective view of the carton blank of the invention positioned on a forming die or folding head in readiness for folding in accordance with certain carton structure and method aspects of the invention;
  • FIG. 3 is a view of the carton in a partially folded state showing further important aspects of the invention.
  • FIG. 5 is a cross sectional view taken along line 55 of FIG. 4;
  • FIG. 6 is a layout of the blanks for cut-out from a single piece of board according to a feature of the invention.
  • FIG. I A blank 10 is shown in FIG. I with the side forming the interior of the carton or box facing up.
  • the blank includes a grid S of score lines along the width and length of the blank and slits ll, 12 at the sides of the blank 10, which together define the plurality of panels and flaps of the carton.
  • a bottom panel 13 is provided with side panels l4, l5 articulated along parallel score lines to the sides thereof.
  • major end panels l6, 16' To the other two sides of the side panel 15 are attached major end panels l6, 16'.
  • the slit 12 in the blank 10 delineates one side of an end flap 18, I8 articulated to the sides of the bottom panel 13; the opposite edge of the end flap l8, 18' being defined by the slit 11.
  • Minor end panel strip l9, 19' form the remainder of the novel portion of the blank 10.
  • a major top panel or closure 20 with gusseted end flap 21, 21' is provided at one end of the blank 10.
  • a minor top flap 22 that may include an appropriate tear strip for ease of opening is positioned at the opposite end to complete the blank 10.
  • the carton blank just described is fabricated of paperboard, preferably of a caliber of approximately 15 points or 15 thousandths of an inch (approximately 0.3 millimeters).
  • the blank is coated on both sides with a relatively thin coating of a thermoplastic composition, such as polyethylene or other synthetic plastic materials.
  • the board may be coated with compositions including high melting point waxes.
  • the coating must provide a good moistureproofing characteristic to the paperboard, and must provide a satisfactory heat bond when the coating is heated by hot air (so as to become tacky) and then pressed together with an adjoining part of the carton.
  • the coating must also be sufficient to form caulking at the sealed joints in accordance with the invention.
  • a coating of 4 pounds per 1,000 square feet of stock on the inside of the carton and 3 pounds per 1,000 square feet on the outside has been found to meet these objectives although it is to be understood that this may be varied to suit the specific application of the resulting carton as desired or necessary.
  • FIG. 2 illustrates a process station at which the thermoplastic coating preapplied to the carton blank may be suitably activated to form an adhesive.
  • a manifold complex 30, 30 is provided on each side of the station to supply heated air, preferably at extremely high temperatures in the order of 900 F. to I00O F. for very brief periods of time.
  • Nozzle boxes receive such heated air from a source as indicated, and direct the air against the blank, at thedes'ire'd locations. These nozzle boxes have been designatedby reference numerals 31-33 and 3l'33, as shown in FIG. 2.
  • the nozzle boxes have slotted or multiple aperture openings therein to release the heated air immediately adjacent the blank to heat the thermoplastic coating to a state of tackiness so that it then becomes an activated adhesive.
  • the nozzle boxes 31, 31 release air to the region of the edge along the major end panels 16, 16' through a suitable slotted orifice 35 to form an adhesive area A as clearly shown in FIG. 2A.
  • the air is directed to the underside of the blank (shown by light shading in FIG. 1) and directed for full heating of the edge that forms an important part of the side seam seal, as will later be seen.
  • the amount of excess heating of the interior area of the blank is also advantageously minimized by the outward direction of the nozzle 35.
  • the second nozzle box 32, 32' (FIG. 28) serves to eject air on the lower portion of the major end panels l6, 16' to form the seal strip area A
  • This area A is shown by heavy shading in FIG. 1 since it is formed on the near side of the blank 10.
  • the slot 36 is directed downwardly to thus engage the region of the end panel adjacent the bottom of the cartonjApertures 37 also in box 32, 32 may be seen in FIG. 2B, which apertures perform the function of ejecting hot air against the upturned end flaps 18, 18, as shown in FIGS. 2 and 2C.
  • the springiness of the board serves to hold the flaps at an acute angle to the face of the box 32, 32' so that only the lower portion of the flaps 18, 18' are heated, and thus only a limited strip A of adhesive is activated on these two parts of the blank.
  • the full width area lying between the slits ll, 12 is the area necessary to have activated adhesive.
  • the flap 18, 18' advantageously deflects a portion of the hot air around the sides and onto the grid S of score lines immediately adjacent thereto so as to activate or enhance the activation of the coating in areas A A for a purpose that will presently be seen.
  • the nozzle box 33, 33, shown in FIG. 2D ejects air from a downwardly directed slot 38 across the full width area A of the panel strip 19, 19 and in addition includes the adjacent score lines S, also for an important reason that will more fully appear below.
  • the blank 10 of the present invention is particularly adapted by the shape of its panels to be formed on high speed, automatic machinery of the plunger and die type.
  • the blank 10 may be positioned on the top of the die, at the process station shown in FIG. 2, in readiness for the application of a plunger to engage along the bottom panel 13. This serves to draw the blank 10 through the throat of the die causing the side panels 14, 15 to be erected to the upstanding position and the end panels 16, l6, l9, l9 and end flaps 18, 18' to be folded to their overlying positions for bonding together.
  • the areas A A are bonded to each other to form the bottom of the box, and areas A,, A are bonded to form the side seam (see FIG. 4 also).
  • the triangular shape of the tab 40, 40 gives progressively greater strength near the base thereof for maximum bending resistance as the flap is erected when the blank 10 is placed in position by the transport device (not shown). Also, only point contact of the apex or top of the tab 40, 40 is assured as the final movement down into the die takes place, thus assuring against significant adhesive transfer to the nozzle box 32, 32'.
  • the tabs 40, 40 are also functionally important in the downward folding process immediately after the box 32, 32' is cleared. At this point it is important that the flaps 18, l8'-not be allowed to fly back because of the springiness in the board to their original position.
  • the guide tab 40,40 prevents this.
  • Vertical edge 41, 41 of the tab (FIG. 3) is captured and held in the proper relationship by the end panels 16, 16' as they are plowed into position along the end of the carton. Since the adhesive has been activated only along the strip A the guide tab has substantially free sliding movement over the corresponding panel 16, 16' (see FIG. 3).
  • the cooperating heated areas A A., with the tacky adhesive come together at the end of the guiding movement and form a watertight bond and seal.
  • the sliding edge 41, 41 gathers excess adhesive in the areas ,A A, for concentration at the corner for enhancing the seal formation in the area A, along the score line as desired.
  • this concept employs abutting the free edges of the carton portions snugly into engagement with raised fold beads 50 that form the grid S and forming a caulking" line at these points.
  • the nature of the embossed fold beads that forms all of the score grid S of the blank should be fully understood and can be seen in FIG. 2D.
  • the embossment or fold bead 50 that delineates the line between the side panel 14 and the minor end panel strips 19, 19 is shown.
  • the raised or convex surface of the embossment is on the inside side of the carton blank, and the concave portion is on the outside. This is of importance since the raised surface forms an abutment for interaction with the free mating edge of the cooperating carton portion.
  • FIG. 5A shows in enlarged detail how the major end panel 16 is brought toward the fold bead 50 by the plunger and die mechanism of the carton forming machine; it being understood that such mechanism is not shown or described herein, but is adequately described in the prior art aforementioned I-Ioyrup et al. US. Pat. No. 3,394,635 and incorporated herein by reference.
  • the panel strip 19 is being closed into overlying engagement therewith.
  • the outer face area A of the major end panel 16 has had the thermoplastic coating transformed into activated adhesive (see FIG. 2A); whereas, the area A A has activated adhesive across the full expanse of the panel strip 19, and also importantly, the raised fold bead 50, all as explained above.
  • an excess of thermoplastic sealing material forming a caulking line 53 is formed in the niche at the point of abutment between the free mating edge and the bead 50. This caulking line 53 is noted to be at the interior of the carton l0, and thus forecloses any chance of leakage of material to the exterior of the panel 16.
  • FIGS. 7A and 7B show the construction for improved sealing of the four bottom corners of the carton.
  • the sealing of the corners is important to prevent leakage through pinholes that heretofore have resulted when the three panels of a carton come together to form a point.
  • This concept constitutes terminating the slits l 1, 12 approximately at the outer limit of fold bead 70 (a distance AX from the center line).
  • this feature causes corner fold beads, that is, intersecting fold beads 70, 71, (shown in FIG. 7A) to pucker or gather toward the corner.
  • This excess material and the activated thermoplastic coating caulk the corner thereby assuring a tight seal and elimination of any tendency for a pinhole to develop, as can be seen in FIG. 7B.
  • the embossed beads 60 were approximately 2 millimeters in width and the distance AX of approximately I millimeter was adopted. Generally speaking then, the slits ll, 12 are patterned to terminate at the outer limits of the score beads which has been found to give a satisfactory sealing of the corner of the box.
  • FIG. 6 The approach for minimization of wastage when cutting the carton blanks from flat stock is shown in FIG. 6.
  • the adjacent carton blanks 10 are oppositely directed so that the major end panel 19 of one is contiguous to the minor end panel 16 of the adjacent carton 10. Further, the end flaps 18 are contiguous to each other.
  • the wastage is limited to the very small cutouts formed at the ends of the tope of the package, and each portion of the blank remaining is functional, as set forth above, so that the blanks 10 fully meet the important objective of conservation of the paperboard.
  • the carton 10 of the present invention has been shown to accomplish results and advantages not heretofore gained in the art.
  • the carton is not only characterized by its design for minimum size blank for a given carton size and minimum paperboard wastage, but most importantly, this has been accomplished while forming a box that eliminates leakage channels and pinholes for true leakproof construction.
  • the fold beads 50, 60 cooperate with the free mating edges of the carton panel and flap 16, 18, respectively, to assure the formation of the liquid-tight seals that are aided by the special caulking characteristics.
  • the end flap 18 has guide tab 40 that assures proper adhesive activation and positioning of said flap with respect to the major end panel 16 in proper underlying relationship therewith.
  • a foldable carton of paperboard or the like having overlying panels to be bonded to each other by thermoplastic adhesive material on at least one of each pair of the surfaces to be bonded comprising a bottom panel, a pair of major side panels articulated to opposite sides of said bottom panel, major end flaps articulated to the other two sides of said bottom panel, major end panels articulated to two upstanding edges of one of said side panels, the width of said end panels and said end flaps being substantially the same as said bottom panel for full overlap, minor end panel strips articulated to the upstanding edges of the other side panel to overlie the free edge of said major end panels, said end flaps having a thermoplastic adhesive material strip across the full width thereof adjacent said bottom panel for bonding to said major end panel, and said end flaps each including a guide tab above said strip only on the side adjacent said major endpanel for extended engagement with said end panel for guiding the same during folding,
  • said carton being formed of blanks cut from flat stock, adjacent blanks being oppositely directed with the major end panel of one beiing contiguous with the minor end panel strip of the other, said end flap including said guide tab of one blank being formed in the stock contiguous to said end flap including said guide tab of the of the other blank, and the adjacent guide tabs on the flat stock being defined by a diagonal bisecting line, whereby said tabs are triangular to give maximum resistance to bending during folding and simplicity of blank cutting and whereby a full sealed bottom is assured while paperboard is conserved.
  • a foldable carton of paperboard or the like having overlying panels to be bonded to each other by thermoplastic adhesive material on at least one of each pair of the surfaces to be bonded comprising a bottom panel, a pair of major side panels articulated to opposite sides of said bottom panel, major end flaps articulated to the other two sides of said bottom panel, major end panels articulated to two upstanding edges of one of said side panels, the width of said end panels and said end flaps being substantially the same as said bottom panel for full overlap, minor end panel strips articulated to the upstanding edges of the other side panel to overlie the free edge of said major end panels, said end flaps having a thermoplastic adhesive material strip across the full width thereof adjacent said bottom panel for bond ing to said major end panel, and said end flaps each incuding a guide tab above said strip only on the side adjacent said major end panel for extended engagement with said end panel for guiding the same during folding, said guide tab of said end flap being substantially free of adhesive material to allow relatively resistance-free guiding movement against said major end flap during folding.
