Definitions

  • Coated paperboard containers are being used in increasing quantities as fluid containing bottles in place of other commonly used means.
  • the success of this new container has caused much demand for new and various sizes.
  • the largest size coated paperboard container in general use holds a half gallon of fluid.
  • certain characteristic of the container is required to be modified to give satisfactory service.
  • Milk is now shipped many miles from bottling plants and in normal transportation methods is subjected to continuous vibrations.
  • In many of the present containers there is overhang of the main bod-y and side walls over the bottom panel members. This causes a bellows actions at the bottom of the container between the bottom panels and the side walls. The bellows action can cause a failure of the container by the coating becoming fatigued and cracking, thus, allowing the fluid to leak out of the container.
  • the major objective of the present invention is to provide a bottom structure such that there is not a bellows action between the side walls and the bottom panels.
  • FIG. 1 is a layout view of a inside surface of a container blank showing the inventive structure
  • FIG. 2 is a perspective view of a container fabricated from the blank shown in PEG. 1;
  • H6. 3 is a side elevation of the container shown in H6. 2;
  • FIG. 5 is a view showing the outside bottom structure taken on the line 5-5 of FIG. 3;
  • FIG. 6 is enlarged exaggerated view showing a typical corner generally indicated as FIG. 6 in FIG. 4-;
  • FIGS. 7, 8, 9 and 10' are fragmentary perspective views illustrating sequentially the various steps in forming the bottom closure of the container of FIG. 2;
  • FIG. 11 is a flat side seamed blank made from the blank shown in FIG. 1 and showing the outside surface thereof.
  • the bottom closure group is the bottom closure group and comprises major bottom closure flaps 25 and 27, first minor bottom closure flap 26, second bottom closure flap 28 and side seam flap 17.
  • the bottom closure group is defined on the sides by edge 18 and 19 and the fiaps are separated by the score lines 21 through 24.
  • the major flap 25 has an extended tuck-in member 31 and major flap 27 has an extended tuck-over member 32.
  • the first minor flap 26 is flanked by trapezium fold-back members 33 and 34- and connected thereto by score lines 35 and 36 respectively.
  • the second minor flap 28 is flanked by trapezium fold-back members 37 and 3h and connected thereto by score lines 4-1 and 4'2 respectively.
  • the container blank 10' as shown in FIG. 11 is in the form in which it will be fabricated on packaging machines, for example the unit disclosed in US. Patent No. 3,602,328 which issued October 3, 1961.
  • the container blank id is opened up into a tubular form as seen in FIG. 7.
  • the major flaps 25 and 27 are moved towards each other.
  • the minor flaps 26 and 28 are moved towards each other. This causes fold-back member 38 to rotate around score line 24; so that the inside surfaces of member 33 and flap 25 are coming together.
  • member 38 is rotating around score 42, thus the outside surfaces of member .38 and flap 28 are coming together.
  • Fold-back members 33, 35, and 37 make the same movements as member 38 with panels 2-5-26, 2726 and 27-23 respectively.
  • Bottom closure major flap 25 moves towards bottom closure major flap 27 just enough faster than flap '27 moves towards flap 25 so that tuck-in member 31 is positioned between foldback members 3338 and major flap 25.
  • FIGS. 7 through 10 shows the bottom when completely closed. if the container is pie-coated with heat scalable material the bottom flaps can be heated -to activate their coating to form a bonded surface when joined together. If the container is not of the pre-coated type bonding material may be applied to the flap areas which meet when the bottom is formed so they will bond when they meet.
  • the score lines 12, 35, 36 and 12, 41, 42 on flaps 26 and 28 respectively form isosceles triangles with the intersection of the score lines 35, 3'), 41 and 42 with score line 12 a predetermined distance from the score lines 21, 22, 23 and 24 respectively.
  • the triangle on fiap 2d has equal legs 35 and as with their intersection 51 on the bottom edge of the blank 10 and equal distance from the score lines 21 and 22.
  • the triangle on flap 28 has equal legs 41 and 42 with their intersection 52 on the bottom edge 2% of the blank 10.
  • Score li. e 41 and d2 intersect score line 12 at predetermined distances from score lines 23 and 24 respectively which are not equal.
  • the intersection of lines 12 and 42 is further from score line 24 than the intersection of lines 12 and 4-1 is from score line 23.
  • the distance from score line 23 to the intersection of lines 12 and 41 is equal to the distances score lines 21 and 22 are from the intersection of lines 1235 and 12-36 respectively. Therefore, the intersection 52 will not be equal distance from score lines 23 and 24 but will be closer to 23 than 24. The distances from line 12 to intersections 51 and 52 will be just short of half the distance between lines 22 and 23. The purpose of this will be explained further in the specification.
  • FIGS. 2 and 3 show the container as it appears after being completely constructed.
  • FIG. 4 shows a view of the bottom closure as seen from the inside of the container. Intersections 51 and 52, as seen in FIG. 4-, will be just touching or just short of contacting. This will require panels 14 and 16 to be close enough together that will not form an overhang at score line 12 of flaps 25 and 28 respectively. This occurs because the distances from the intersections 51 and 52 to score line 12 are equal and just less than half of the distance from score lines 22-23 and 21-2i as constructed.
  • FIG. 5 shows th appearance of the bottom closure as viewed from the outside of the container. As seen in this view the panels 14 and 16 do not overhang the score lines 21-22 and 2324 respectively.
  • FIG. 6 shows an enlarged view of the bottom corner formed at score line 23. It can be seen how the score line 41 starts towards the center of the container just to one side of the inside bulge of score line thus preventing the score from forcing the fiap 28 away from the center of the container and in this way holding the container panel 16 back so it forms an overhang as to bottom closure fiaps.
  • the predetermined distances of the intersection of score lines 35', 36, 41 and 42 are based on the thickness of the container paperboard being used.
  • An example of sizes and dimensions that could be used would be a liquid gallon container having a width of panel 15, the distance from the middle of score line 22 to the middle of score line 23, of 5.531 inches and all other panels equal to this except panel 13 which will be .040 of aninch shorter with the additional length of this wall of the container coming from the side seam flap 1"].
  • the distances from intersections 51 and 52 to the middle of score line 12 being 2.750 inches.
  • the thickness of the container walls being .028 of an inch.
  • the distances of the intersections of score lines 35, 36 and 41 with score line 12 from score lines 21, 22 and 23 respectively being .125 of an inch and the distance of the intersection of score line 42 with score 12 from score line 24 being .187 of an inch.
  • the present invention discloses a new and improved bottom structure for an infolded bottom which will not permit overhang and can be fabricated on presently available equipment.
  • the container When the bottom is made, the container will be in tubular form as shown in FIG. 7 and mounted on a mandrel.
  • the mandrel will terminate at score line 12 and have a fiat end. Therefore, when the bottom closure flaps are closed they are over the end of the mandrel.
  • a pressure pad will act on the container bottom closure flaps to assure proper bonding of the bottom.
  • the pressure pad will have such a contour that it will force the bottom flaps against the mandrel end with uniform pressure. This causes part of flap 25 to move closer to the mandrel end because of side seam flap 17 which is bonded to the inside surface of flap 25 and this change in levels is shown by fold line 25'. For the same reason we have fold line 27' where flap 27 folds over the end of tuck-in flap 31.
  • a fold-in bottom end closure for a tubular container having,
  • each of said trapezium members having one side connected to one leg of a minor triangular flap, one side connected to a major flap, one side connected to a wall panel and the fourth side not connected,
  • said minor flaps are connected to alternate wall panels and have at least three sides,
  • the trapezium members have one side connected to one major flap and one side connected to a wall panel
  • a blank for a container according to claim 4 having,
  • each of said pair of trapezium members having at least one leg connected to a major flap
