Definitions

  • some containers have been developed having different sealing means in the folded sealed top portion.
  • some seams are provided in said folded sealed top portion which have a substantial adhesive force in order to keep the container liquid-tight during transportation and prior to opening thereof while other seams at least in part have a low level of adhesive force allowing thereby an easier opening of said folded sealed portion in such a way as to form a pouring spout for satisfactorily pouring out the contents of the container.
  • Said sealing area could be formed by a pattern of raised surfaces which alternate with areas which are disposed therebeside and at a lower level.
  • Representative of this art is for example EP 185,325 of Tetra Pak International AB which discloses a package made of a supporting material such as cardboard, coated with a thermoplastic material, for liquids or the like, comprising a tubular main body with a base and a cover which is folded into a ridge shape and has a pouring spout which can be opened by opening sealed seams, wherein the sealing region of the spout contains sealing sections with strong adhesive power and adjacent sections with low adhesive power for peeling the sealing sections apart, and wherein the sealing section with low adhesive power is formed by a pattern of raised surfaces at a spacing from one another, alternating with adjacent sections at a lower level, wherein the region with low adhesive power extends into the ridge area and into the lateral triangular sections of the ridge. Areas with low adhesive power are so-called abhesive pads.
  • containers disclosed in GB 2 253 608 and US 4 821 950 Other examples of containers that have to be opened by means of 2 consecutive actions comprise containers disclosed in GB 2 253 608 and US 4 821 950.
  • Another disadvantage of the known containers is that the cardboard of the container creases which results in lowering the stiffness of the container. Lower stiffness may also lead to spillage due to partial removal of a multilayer by acting on the pulling device disclosed in DE-2 650 092.
  • An additional advantage using the present invention is that the quality of the abhesive pads if present, is less critical and that less thick board with lower stiffness can be used, as opening is less dependent on said stiffness.
  • the present invention is a container comprising a container body, a bottom at a first end of the body and a folded sealed top portion at a second end of the body, said folded sealed top portion comprising means for its opening so as to form a pouring spout characterized in that said opening means comprise a pulling device affixed to part of said folded sealed top portion, and to the inner face of said top margins (68), said pulling device extending downwardly when the container is prepared for use.
  • the main feature of the present invention is that said folded sealed top portion comprises opening means for opening said top portion so as to form a pouring spout.
  • Said opening means comprise a pulling device affixed to part of said top portion inwardly folded, generally in the region of said main triangular portion. Once said top portion has been raised from its sealed position to provide wings, the pulling device of the present invention helps to pull said top portion outwardly so as to peel the top margins of the side portion away from sealing relationship with the top margins of the front and the rear portions. This action provides a spout from which the fluid contained in the container may be poured or, if desired, drunk directly from said container.
  • the container front and rear portions can as a variation contain one or more score lines which, upon opening of the carton, act as part of the pour spout, and allow for easier pouring from the carton.
  • Fig. 3. shows the same carton as shown in Fig. 2, but filled and sealed.
  • Fig. 4. shows the same container as in Fig. 2 and/or 3, filled, and in a first stage of opening.
  • a carton blank 2 comprises a sheet of paper-board coated on each of its two sides with thermoplastic.
  • the blank is provided with score lines 4, 6, 8 and 10 to define front and rear panels 12 and 14 respectively and left and right-hand panels 16 and 18 respectively and a joining strip 20.
  • the joining flap 20 extends above and below the score lines 22 and 24.
  • the upper portions 28 and 32 of sides 16 and 18 are pushed inwardly to cause inward folding along the score lines 54 and 74 of the portions 28 and score lines 58 and 76 of the portion 32.
  • the first part of such a folding sequence is seen clearly in Figure 2. Further pushing of those upper portions in an inward direction and downward depression of the portions 52 of the panels 12 and 14 causes the areas 66 and 70 to approach each other, sandwiching the areas 68 and 72 between them. The outer surfaces of the areas 68 and 72 also lie in contact with each other and the tabs 82 and 84 are folded around the outer surface of the strip 77.
  • the folded-over portions 66, 78 and 70, 76 are first raised to revert to the position seen in Figure 4 and the tab 82 is unpeeled from around the end portion of the strip 75.
  • the pull tab 86 is then firmly grasped between a finger and thumb of one hand whilst the carton is held by the other hand. Pulling of the tab 86 in a direction away from the carton separates the inner surfaces of the areas 68 and 70, and continued pulling causes the portion 28 to bend about its score lines 22, 54 and 74 to form a spout 88 as seen clearly in Figure 6. Tab 86 is removed from its adhesive connection with the inner face of the area 68 by simply pulling it away therefrom.
  • a reinforcing band 90 is provided encircling the girth of the carton as seen in Figure 7.
