Definitions

  • the present invention relates to gable top containers which are typically manufactured from liquid impervious sheet paper and typically contain milk and other beverages.
  • the present invention relates to an improved gable top container structure which permits easier opening of the container.
  • BACKGROUND ART Gable top containers are widely used for milk, frui juices, and like liquids and have many advantages including light weight, low cost and ease of disposal since the containers are non-returnable and can be easily burnt.
  • a gable top container structure for a four sided carton in which two, opposite, shorter sides are each bent into a V-shape and inwardly inclined between two, opposite, longer sides which are sealed together along their upper edges to form a gable, the upper edges of said lower sides being sealed together with said longer side upper edges, wherein an elongated gripping means is located adjacent the upper edge of one of said shorter sides at least part of, said gripping means being located between said sealed upper edges prior to opening said carton thereby effectively sealing said carton.
  • Fig. 1 is a perspective view of the upper portions of a closed, gable top container in accordance with the preferred embodiment of the present invention
  • Fig. 2 is a view similar to Fig. 1 but showing the container partially opened;
  • Fig. 3 is a schematic view illustrating how a memorized container blanks are stamped from a strip of sheet material
  • Fig. 4 is a view similar to Fig. 3 illustrating how container blanks are stamped from a strip of sheet material in order to make the carton of Figs. 1 and 2;
  • Fig. 5 is a view similar to Fig. 1 but of a second embodiment
  • Fig. 6 is a view similar to Fig. 2 but of the embodiment of Fig. 5;
  • Fig. 7 is a view similar to Fig. 1 but of a third e bodi ent.
  • Fig. 8 is a view similar to Fig. 2 but of the embodiment of Fig. 7.
  • the container is generally similar to a conventional gable top container.
  • the container has four sides, two long sides 1 and two shor sides 2.
  • the shorter sides 2 are each bent into a V-shaped fold and inwardly inclined between the two longer sides 1. It is to be understood that the indications inwardly, upwardly, downwardly, outwardly etc. as used herein are taken with reference to the normally upright attitude of a conventional gable top container.
  • the upper edges 3, 4 of the shorter sides 2 are positioned within and below the upper edges 5 of the longer sides 1. Then the longer sides 1 are sealed along a strip having a depth 6 by means either of heat sealing or some other conventional means such a sonic welding.
  • the depth of sealing 6 is indicated in Fig. 1 and is of a sufficient vertical extent to include the upper edges 3, 4 of the shorter sides 2 thereby effectively sealing the container.
  • a quasi-semicircular extension 9 is provided on the upper edge 3 of one of the shorter sides 2.
  • the extension 9 consists of another portion of the sheet material from which the container is formed and therefore forms a prolongation of the one short side 2. It is only necessary for a single extension 9 to be provided since suc containers are normally intended to be opened from only one side.
  • the extension 9 is folded outwardly and downwardly onto the shorter side 2 which is then folded inwardly to form the V-shape apparent in Fig. 2. Then the longer sides 1 are brought together during the sealing process and it will be apparent that the base 10 of the extension 9 is included within the sealing depth 6 whilst the tip 11 of the extension 9 is not included within the depth of sealing 6.
  • O ⁇ .. container are very weak.
  • the extension 9 and in particular th tip 11 thereof is able to be easily grasped by the fingers of the person opening the container and the upper edge 3 pulled to the right as seen in Fig. 2 and away from the remainer of the container.
  • the extension 9 can be turned upwardly and folded about its longitudinal axis so as to form a pouring spout 12 which greatly assists in regulating the flow of liquid from the container when it is desired to pour liquid therefrom.
  • the term "gable top container” as herein defined includes within its scope containers having varying angles of the ridge or sealing flange formed by the edges 5. Thus the angle of approximately 45° for the inclination of the sides 1, 2 from, the vertical at the top of the container is not critical. In particular, the present invention is entirely applicable to flat topped containers (termed bricks) having a flat rather than pyramidal top, but retaining the vertically extending sealing flange formed by edges 5. In the brick container the inclination of the sides at the top of the container is approximately 90 from the vertical.
  • Fig. 3 the arrangement whereby blanks for conventional gable top containers are stamped from a strip of sheet material, is illustrated. Each blank consists of a pair of long sides 1, and a pair of short sides 2. Running along the length of the blank is a side sealing strip 15. In addition, the base of the container i formed by folding the sides 1, 2 and then sealing a base sealing strip 16 in position.
  • the extension 9 can be provided as a separate, rather than an integrally formed, item.
  • the extension 9 can be separately formed from fabric tape, for example, and adher to the edge 3.
  • the upper edge 3 of one of the shorter sides 2 provided with an elongated strip which, prior to opening, extends downwardly through the zone of sealing 6 so that t tab 19 carried on the free end of the strip 18 is located between the corners 7 and 8.
  • the strip 18 can be formed o any convenient material being either stamped from the same material as the carton blank is stamped or alternatively being formed separately and joined to the upper edge 3 adjacent the centre thereof.
  • the strip 18 ca be formed from tape or even cord.
  • the container is easily opened and th contents can be easily poured from the container by using the upper edge 3 as a pouring spout.
  • the strip 18 does not hinder this pouring action since the strip 18 will always b directed in a more vertical direction during pouring than the actual stream of liquid.
  • a third embodiment of the present invention is illustrated which makes use of a filament 25 which can be formed from cotton, plastics, or any other conventional material from which threads are formed.
  • the filament 25 is formed into a long loop 26, the ends 27 of the filament being knotted together at 28.
  • the knot 28 is positioned to the far side of the centre of the upper edge of the short side of the container which is hidden in Figs. 7 and 8.
  • the knot 28 is located within the sealing depth 6 and between the upper edges 5 and thereby forms an anchor.
  • the filament 25 extends along only the centre portion of the length of the upper edges 5 and a mid-portio 29 protrudes beyond the container.
  • the filamen 25 passes over the upper edge 3 adjacent the corners 7, 8 and passes below the edge 3 and also below the depth of sealing 6.
  • the centre 30 of the filament 25 is located adjacent the centre of the upper edge 3. In order to open the * container illustrated in Figs.
  • C operation is to separate the upper edges 5 along approximately half their length.
  • the second operation is t separate the upper edge 3 from the longer sides 1 thereby opening the container. This operation takes place as the mid-portion 29 is pulled away from the container 1 so as to draw the centre 30 and adjacent portions of the filament 25 from behind the upper edge 3. Thereafter the edge 3 can be easily moved manually into the pouring configuration illustrated in phantom in Fig. 2. In this configuration, the filament 25 is located adjacent the still sealed portions of the edges 5, well away from the pouring lip formed by the centre of edge 3.
