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 characteristics of the container are required to be modied to give satisfactory service.
  • One of the problems that has arisen in the packaging industry with the coming of larger size containers, such as the gallon container is the diiiiculty in opening due to the heavier caliper paperboard.
  • the increased amount of material in the larger size containers when the past standard container design is used, has changed the geometry so that a large amount of material would collect around the pouring spout causing it to be damaged while opening.
  • Another object of this invention is to provide a container which includes a sanitary extensible pouring spout completely protected within the containers end closure, and capable of accomplishing these objectives with the minimum material and fabrication cost, while providing a reliable container of simple and rugged construction.
  • a further object is to provide a ⁇ container with a sealed integral infolded pouring spout that may be unfolded with ease into pouring position while maintaining the sanitary quality of the spout.
  • the object of the present invention includes a means of providing a container with a sealed integral infolded pouring spout that may be unfolded with ease without damage when opening, and an integral means which will provide a pop-open and pop-close feature.
  • FIG. l is a layout View of an inside surface of a container blank showing the inventive structure
  • FIG. 2 is a flat side seamed blank made from the blank shown in FIG. 1,. showing the outside surface thereof;
  • FIG. 3 is a perspective view of the container fabricated from the blank shown in FIGS. 1 and 2;
  • FIG. 4 is a front view of the container showing the relationship of the fold-in end panel of the pouring spout;
  • FIG. 5 is a perspective View showing the container pouring spout during opening
  • FIG. 6 is a perspective view showing the back of the pouring spout during opening.
  • FIG. 7 is a perspective view similar to FIG. 6, showing the pouring spout extended.
  • the inside surface of the flat blank 10 is shown with a pattern of appropriate score lines.
  • the container is separated into three groups by staggered score lines 11 and 12.
  • the portion of the container blank below score line 12, as seen in FIG. 1, is the bottom closure group.
  • a discussion of the bottom closure group is not necessary in the disclosure of the present invention; however, a complete description is given in U.S. Patent No. 3,120,333, which issued February 4, 1964.
  • the material between score lines 11 and 12, as seen in FIG. 1, is a body group and comprises four panels 13 through 16, and a side seam ap 17.
  • the blank 10 is delined on the side by edges 18 and 19, and with the panel being separated by score lines 20 through 23.
  • roof panel 25 An integral portion of roof panel 25 is the outer rib panel 29 connected therewith along score line 24a. rlhe outer rib panel 29 is located between score line 24a and the transverse score line 30 which has sealing flap 31 above it.
  • the integral portion of the roof panel 27 is the outer rib panel 32 connected therewith along score line 24C.
  • the outer rib panel 32 is located between score line 24e andthe transverse score line 33 which has sealing flap 34 above it.
  • Embodied in the roof panel 25 is area 35 which is deiined by score lines 11, 20, 24a and dog leg score line 36. Dog leg score line 36 extends between score line 11 and score line 24a in two sections 36a, 36h, as seen in FIG. 1.
  • Embodied in roof panel 27 is area 37 which is dened by score lines 11, 21, 24e and dog leg score line 38.
  • Dog leg score line 3S extends between score lines 11 and 24C in two sections 38a and 38h.
  • Side panel 14 has connected therewith along score line 11, triangular fold-in end panel 26 which is defined by score lines 11, 41, 42.
  • the panel 26 is anked by two triangular fold-back panels 43, 44 connected along score lines 41, 42, respectively.
  • Connected to panels 43, 44 are inner rib panels 45, 46, respectively.
  • Inner rib panels 45, 46 are connected by score line 47.
  • Edge 48 runs between score lines 20, 21 along panels 45, 46.
  • Side panels 16 has connected therewith along the score line 11, a triangular fold-in panel 28 which is defined by score lines 11, 51, 52.
  • the panel 28 is flanked by fold-back panels 53, 54 connected along score lines 51, 52, respectively.
  • Connected to panels 53, 54 are inner rib panels 55, 56, respectively.
  • Inner rib panels 55, 56 are connected by score line S7.
  • Edge 58 runs between score lines 22, 23, along panels 55, 56.
  • the blank 10 in FIG. 1 is used; however, the blank is first side seamed as viewed in FIG. 2. This is accomplished by having panel 16 and side seam flap 17 folded about score line 22 until their inside surfaces contact the inside surfaces of panels 15, 14, respectively. Then, panel 13 is folded about score line 28 until its inside surface contacts the inside surface of panel 14 and the outside surface of side seam flap 17. The inside surface of panel 13, along edge 18, will contact outside surface of side seam fiap 17. The area of panel 13 contacting flap 17 is heated to activate its coating for side seam heat sealing, or bonding material may be applied to the surface to accomplish the side seaming operation.
  • the blank is then opened into a tubular form, substantially square in cross-section, and the bottom end closure is completed as described in the above mentioned U.S. Patent No. 3,120,333.
  • the side seamed container blank has been opened and the bottom end closure made, it is then filled with the desired product.
  • the top panels are infolded into a gable form.
  • the score lines 41, 42, 51, 52 are broken by infolding the triangular fold-in end panels 26, 28 towards each other.
  • the thermoplastic coating is directly adhesively activated on the inside surfaces of the outer rib panels 29, 32 and the sealing flaps 31, 34; and on the inside and outside surfaces of inner rib panels 55, 56.
  • FIGS. 4 through 7 the new opening characteristics of the container will be explained in detail.
  • the container is shown in front view, with dog leg score line 36 contacting score line 11 away from the intersection of score lines 11 and 20, and contacting score line 24a closer to score line 23 than score line 20.
  • a phantom line 26 representing fold-in end panel 26 is shown in FIG. 4. This panel 26 will run from score line 11 at an angle up to score line 24a in a straight plane, and it will intersect score line 24a closer to score line 20 than score line 23.
  • FIG. 4 the container is shown in front view, with dog leg score line 36 contacting score line 11 away from the intersection of score lines 11 and 20, and contacting score line 24a closer to score line 23 than score line 20.
  • a phantom line 26 representing fold-in end panel 26 is shown in FIG. 4. This panel 26 will run from score line 11 at an angle up to score line 24a in a straight plane, and it will intersect score line 24a closer to score line 20 than score line 23.
  • dog leg score line 36 is so constructed that the intersection of sections 36a and 361; will be on one side of phantom line 26 and the intersections of sections 36a and 36b with score lines 11 and 24a, respectively, will be on the other side of phantom line 26.
  • the panel 27 with dog leg score line 38 is not shown in FIG. 4, but dog leg 38 has the same characteristics on panel 27 as dog leg 36 has on panel 25.
  • the score lines 36, 38 are connected to score lines 24a, 24e, respectively, beyond their mid-points to provide score line 47 with a clear area when the container is being opened. Thus, there will not be a concentration of material at score line 47 when the container is being opened which would cause damage to the score line and the pouring spout.
  • the dog leg score lines 36, 38 have been divided into two sections providing an intersection above the plane of panel 26, as viewed in FIG. 4.
  • the panels 25, 27 will break along dog leg score lines 36, 38.
  • the panels 25, 27 are so designed that they will facilitate a natural breaking along a break line 39 as viewed in FIGS. 6 and 7.
  • the break line 39 Will give us, with other score lines, three general areas; namely, top opening area 61, which is defined by break line 39, score line 38b, and score line 24e; panel opening area 62, which is defined by score lines 38a, 38b, and break line 39; and lower opening area 63, which is defined by score lines 11, 38a, and break line 39.
  • the top opening area 61 permits outer rib panels 29, 32, and sealing fiaps 31, 34, to rotate in such a manner as to delaminate past the center of the container, helping to push the pouring spout out, including score line 47 and inner rib panel 45 and 46.
  • lower opening areas 63 are so positioned that they will act on the tips of panel 26 at its intersection with score lines 41, 42, 11, pushing panel 26 from its closed position.
  • Panel opening area 62 will act on fold back panels 43, 44 forcing them up, which will in turn force score lines 41, 42 up, thus causing panel 26 to pop out from its closed position as shown in FIG. 6, into its open position as shown in FIG. 7.
  • score line 38 were so located on panel 27 as to run straight from score line 11 to score line 24C and be, before the mid-point of the panel 27 or score line 24C, closer to score line 21 than to score line 22 when it contacts score line 24e, it would have a tendency to pop panel 26 out from its closed position. This would cause the condition of grouping a large amount of paperboard around the pouring spout at score line 47, causing the score line and pouring spout to be damaged when opening the container; thus providing a defective pouring spout.
  • the action which has just been described on panel 27 with respect to score line 38 and its associated panels, is similar to the action which takes place on panel 25 with score line 36 in its associated panels.
