Definitions

  • the present invention relates to packaging and more specifically to a container bottom closure construction.
  • the invention nds particular, but by no means exclusive, utility in disposable containers adapted for distribution of milk and other dairy products.
  • the usual procedure in erecting the container is to form the blank into a polygonal tube open at both ends and then to close the lower or 'bottom panel extensions, retaining them in place by means of a suitable adhesive. It is presently the practice to coat or impre'gnate the exposed surfaces of the erected tube
  • paraffin coated containers of the above-described type have been commercially successful, there are certain disadvantages inherent in their use, one of the most marked of which involves the parain coating.
  • a suitable dip tank of molten paraffin must be maintained as part of the packaging machinery at the dairy or processing plant. This, along with the extra care and attention required on the part of the operator, plays a part in increasing the cost of the container and finally of the ultimate product.
  • globules of the parain coating may Hake off of the container walls. While this does not impair the sanitary integrity of the contents, it does tend to impair consumer acceptance of the container.
  • thermoplastic substance used is desirably one which is inert to the substances to be packaged, is strong and durable, is inexpensive, and is easy to apply in sheet form onto the paperboard.
  • a coating of' this sort renders the paper sheet material resistant to fluids which would be packaged in the container including such acidic products as milk.
  • thermoplastic substance which is useful for packaging dairy products is polyethylene.
  • thermoplastic materials such as polyvinyl chloride, polyvinylidene chloride, polyvinyl chloride and acetate copolymer, and polypropylene, to name only a few, will find use under favorable circumstances.
  • ICC Paper sheet stock for forming containers is initially supplied in the form of rolls, and as the stock is produced it can be coated on both sides with a layer of polyethylene thermoplastic material.
  • One method of accomplishing this is by heating and stretching the polyethylene and applying it when hot directly onto the surface of the paper to which it becomes tightly bonded.
  • the surface of the paper to be used for the outside of the blank is generally coated with a layer approximately 3A of a mil thick while the inside surface of the sheet -is coated with a layer of polyethylene approximately 1 to 11/2 mils thick.
  • the general aim of the present invention is to provide a new and improved container formed of thermoplastic sheet material, or thermoplastic-coated paperboard sheet material, and which will be strong, simple to erect, close and seal, and susceptible of high volume economical production for packaging milk and other comestibles.
  • a more specific object of the present invention is to provide a container of the above type having surfaces of sanitary heat and pressure sensitive thermoplastic material which not only protects the contents of the container against admission of harmful substances but also serves as a sealing adhesive for effecting tight closure and sealing of the container.
  • Another object of the invention is to provide an improved container of the character set forth and having a bottom closure susceptible of automat-ic closing and sealing to form a strong leak-proof bottom on the container which will remain Huid-tight even under severe conditions of use, such as being dropped on a bottom corner.
  • Still another object of the invention is to provide a container of the foregoing type and having a bottom closure with at least three plies of integrally connected stock at each bottom corner area and a minimal length of raw edge exposed to the interior of the container and the contents thereof.
  • FIGURE 1 is a perspective view of an illustrative closed and sealed container embodying the present invention.
  • FIG. 2 is a layout View of a 'blank from which the container in FIGURE 1 was erected and showing the inside surface thereof.
  • FIGS. 3, 4, 5 and l6 are fragmentary perspective views illustrating sequentially various steps in forming the bottom closure of the container of FIGURE l.
  • FIGS. 7, 8, 9 and 10 are fragmentary perspective views similar to FIGS. 3 to 6 but showing another form of container 'bottom closure also embodying the invention.
  • FIG. 11 is a layout view of the inside face of a blank similar to that shown in FIG. 2 Ibut yadapted to define the bottom closure of FIGS. 7 to '10.
  • FIG. 12 is an outside ybottom View of the container of FIGURE 1 and showing certain embossing of the latter in accordance with a further aspect of the invention.
  • FIG. 13 is an outside bottom view similar to FIG. 12 but showing a container having the bottom closure of FIGS. 7 to l0.
  • FIG. 14 is a view of the inside face of the container bottom of FIG. 13, looking in the direction indicated by the line 14-14 in FIG. 10.
  • the container 20 is formed from paper or other suitable sheet material and is self-sustaining in shape.
  • the sheet material has surfaces of, or is coated with, a thermoplastic material of the type exemplified by polyethylene.
  • the container 20 comprises a tubular body 21 which in the present instance happens to be substantially square in cross section. At its base the body 21 is provided with a bottom closure 22. The upper end of the body 21 in this instance terminates in what will be recognized as the familiar gable top type of end closure 23 which is surmounted by a central laminar rib or truss 24. The top end closure has incorporated therein an extensible spout for dispensing the contents of the container.
  • the container 20 is fashioned from a tlat blank 25 of high-grade paperboard coated with a layer of polyethylene thermoplastic material.
  • the blank 25 (the inner face of which is illustrated in FIG. 2) is divided into a plurality of panels and areas which are utilized for the walls of the container and the closure parts when the container is erected.
  • the central and major area of the blank becomes the body 21 of the container and is defined by spaced apart transverse score lines 26, 28, running in substantially parallel relation across the face of the blank.
  • transverse score lines 26, 28 are not continuous but are formed in staggered portions -interrupted by the perpendicular score lines 29, 30, 31, and 32.
  • the purpose of this staggered sco-ring is to accommodate the thickness of the paper as it is bent along the score lines when the container is erected and thus prevent crowding of the paper at the various corner junctions of the score lines. This not only enhances the strength and appearance of the iinished container but facilitates its erection and closure by automatic machinery.
  • bot-tom closure panels 39, 40, 41, and 42 Connected to the lower edges of the side panels along the lower transverse score line 28 are bot-tom closure panels 39, 40, 41, and 42. Accordingly, alternate side panels 34, 36 have respectively connected therewith opposed bottom closure panels 39, 41. 'Ihe latter in turn include respectively a tuck-in flap 5t) and an overlying or outside overlap flap 51.
  • the tuck-in flap Sti is relieved or recessed at 52 so that it receives the adjacent end 53 of the side seam tiap when the bottom closure is sealed.
  • alternate side panels 3,5, 37 have connected therewith along the transverse score line 28, opposed triangular infold panels 40, 42, respectively.
  • the infold panel 40 is anked by triangular fold-back panels 55, 56 connected thereto along converging score lines 5S, S9, starting at the intersections between the perpendicular score lines 29, and the transverse score line 28, converging downwardly and intersecting at the cut lower edge of the blank (as viewed in FIG. 2,).
  • infold panel 42 is flanked by fold-back panels 6), 61 connected thereto along fold lines 62, 63.
  • triangular fold-back panel 56 is connected to bottom panel 39, panel 55 is connected to bottom panel 41, panel 61 is connected to panel 41, while panel 60 is connected to the bottom portion 53 of the side seam ap 38.
  • transverse score line 26 Integral with the upper ends of the side panels, but separated therefrom by the transverse score line 26, are a plurality of panel extensions which give the top of the container 2t) its characteristic gable shape. These areas include a transverse score line 66 generally parallel to the score line 26 and spaced between the latter and the top edge of the blank 25. The areas below the line 66 define roof panels 68, 69 and triangular end and fold-back panels 75, 78, 79 and 76, ⁇ B8, 89 of the top closure. The areas above the line 66 define the parts of the central laminar rib 24, namely, inner rib panels S4, 85, 94, 95, outer rib panels 70, 71, and sealing iiaps 72, 73. Again score line 66 is not a straight line but includes staggered portions 66a, 66b, 66e and 66d corresponding respectively to the panels 34, 35, 36 and 37, for accommodating the thickness of the paper when the container closure is folded.
  • the blank 25 is transformed into a completed container as illustrated in FIG 1, by iirst folding it upon itself to form a fiat tube and adhesively securing the side seam ap 38 and its extensions 53, 98, 99 to the inside faces of panels 39, 34, 78 and 84.
  • the polyethylene coating as an adhesive for the side seam
  • Such added adhesive is desirably resistant to heat at the melting point of the polyethylene or other coating on the container so that the side seam remains tight during subsequent closing and sealing operations.
  • One polyethylene base adhesive used for the side seam has a melting point of about 500 F.
  • the iiattened blank tube is then erected into a tube of substantially square cross section (FIG. 3) and the bottom closure is completed. Accordingly, the score l-ines or creases 58, 59, 62, and 63 are broken or given a prebend by folding the triangular infold aps 40, 42 inwardly towards each other (FIG. 4).
  • the tuck-in tiap 5) is then in position for insertion beneath end panel 39 and above the triangular fold-back aps 56 and 60 so that the bottom panel 39, which includes the sealing iiap 51, overlies end panel 411, which includes the tuck-in ap (as Viewed in FIG. 5).
  • the bottom closure panels are first broken but before they are finally folded they are subjected to a source of intense heat so as to melt or vat least activate and render adhesively active the coating of polyethylene on both surfaces of the bottom closure panels.
  • a source of intense heat so as to melt or vat least activate and render adhesively active the coating of polyethylene on both surfaces of the bottom closure panels.
  • the heat must be suflicient to partially melt the coating which melts between about 230 and 275 F., depending upon its density.
  • These panels are then folded together and the tuck-in flap 50 is inserted in place.
  • the bottom closure is completed it is subjected to pressure between cooled pressure pads to cool and solidify the polyethylene plastic adhesive and thus produce a completely sealed bottom end closure.
  • the bottom closure panels 4G and 42 are so proportioned that the combined length of the triangullar fold-back panels 55, S6, as well as the combined length of the triangular fold-back panels 60, 61, normal to the score line 28, will be slightly greater than the base width of each triangular bottom closure panel measured along the score line 2S (IFIG. 2).
  • the bottom closure panels are proportioned so that those portions of the vertical score lines 29, 30, 31 and 32, joining the bottom closure panels 39, 4i), 41 and 42, and defining a side of each of the triangular foldback panels, are slighlty longer than one-half the width of each triangular bottom closure panel measured along the score line 28.
  • the cut edges of thc triangular fold-back panels 55, 56, 6! and 61 will enter into positive abutting engagement with each other.
  • the paperboard is crowded together under substantial compression in its own plane las well as transversely thereof. tThe tightness of the ultimate bottom seal is thus materially increased.
  • the container When the container has been erected and the bottom closure sealed, it is normally in a sanitary condition. In some instances, however, it may be subjected to iurther sterilization as by irradiation with ultraviolet light or by dipping in a tank of water at approximately 200 F The sterilized containers are then filled with the desired product.
  • the parts thereof are iniolded into gable form.
  • the triangular panel crease lines 86, 81, 90, 9'1 are broken by infolding the triangular end panels 75, 76 toward each other.
  • the inner and outer rib panels and Sealing liaps 72, 73 are then heated on both sides, as was done with the bottom flaps, to adhesively activate the polyethylene thermoplastic coating.
  • the container is then closed ⁇ as by passing its top portion between a pair of converging shoes which bring the adhesively activated rib panels and sealing flaps together to complete the gable top structure.
  • the rib panels and sealing iiaps are thereupon subjected to substantial sealing pressure which may be derived from cooled pressure jaws leaving the top closure in sealed condition as illustrated in FIG. 1.
  • the top closure seal may, of course, be broken by ⁇ the user through deliberate application of external forces to effect partial disassembly of the top rib 24 and expose the pouring spout housed therein.
  • an additional precaution may be taken, particularly where the container is used for packaging fluids. This. involves the application of increased pressure to selected areas of the closure parts during the pressure sealing operation, producing indentations or embossments in the closure plies which effectively close up incipient fluid escape channels. In the present instance, these areas of increased pressure or ernbossing on'the bottom closure are represented by the crosshatched areas in FIG. 12.
  • Rectangular embossed area 105 on overlying or outside bottom panel 39 has been pressed inwardly forl almost the thickness of one ply of stock. This effectively blocks the incipicnt leakage channels which would otherwise occur along the free-cut edge of the bottom tuck-in flap 5? and the side seam lflap 53.
  • Embossrnents 106 which in this instance happen to be circular, are located primarily on the overlying or outside bottom panel 39 and are adapted to block oi channels at the abutting edges of bottom foldback panels 55, 56, 60, 61.
