Definitions

  • This invention relates to a liquid container provided with a pour opening.
  • the container may be fashioned from a web of paperboard or from individual blanks, the paperboard being provided with liquid impervious laminations.
  • the container is in the general form of a rectangular parallelepiped, commonly termed a brick-type container, which can be formed from a paperboard web of indefinite length or from individual blanks. At least one surface of the web, which is to be the inside of the container, is laminated with liquid impervious materials such as polyethylene, surlyn, and foil. Usually, however, both web surfaces are laminated.
  • the container of this invention is particularly adapted to hold and to dispense liquid foodstuffs, such as milk fruit juices, and drinks.
  • Containers of the type to which this invention relates are often referred to as aseptic containers or packages, since aseptic conditions (sterile atmosphere and the like) usually accompany the package forming and package filling process or operation.
  • the prior art is already aware of this general type of container, as shown for example in U.S. Patent 3,347,444 to Rausing and 3,232,514 to Swede.
  • These packages, in larger sizes (1 liter and above) as well as the package of this invention, is adapted for consumer use, i.e., use wherein the consumer does not necessarily dispense the entire contents of the container in a single pouring operation. Instead, a reclosure of the container is to be made for a subsequent dispensing of a portion of the contents.
  • brick-type packages are often formed with triangular flap ears, known in this art as dog ears.
  • the triangular flap ears are often positioned with the base of the triangle of each ear coincident with the top and bottom edges of the side walls or panels of the carton.
  • the triangular flap ears generally extend along the sides of the carton, being maintained in that position by a spot of an adhesive.
  • the tabs may extend and lie on the top and bottom walls of the carton, also maintained in that position by a spot of adhesive.
  • opening devices and pour spout devices has evolved in this art, such devices facilitating successive openings and reclosings of the dispensing opening or spout.
  • a pour opening is provided in the top wall of the container, the pour opening being die-cut, for example, and covered on its outside surface with a peelable seal membrane.
  • the die-cut has the polymers extruded over the opening on the inside.
  • the die-cut board edges around the perimeter must be covered.
  • a patch is sealed to these extrusions layers from the outside.
  • the pour opening is positioned adjacent to and at one side of one -of the triangular flaps or dog ears. In use, the consumer initially peels off the flexible seal or otherwise ruptures it, to thereby enable dispensing of the carton contents.
  • the user bends back one of the triangular tabs, being that tab closely associated or closely adjacent to the pour opening such that the tip of the dog ear enters the opening and extends underneath it, with the rigidity or stiffness of the dog ear maintaining it up against the interior surface of the container.
  • contamination of the contents of the carton is inhibited by blocking the pour opening with a portion of the triangular flap ear.
  • the pour opening may be provided on the top of the carton, or on one of the sides, or be positioned underneath one of the triangular flap ears at the top of the carton. In each case the opening is on any panel that does not have a fin seal.
  • the pour opening is so configured as to maximize its area of closure by the triangular flap ear.
  • While the invention is illustrated in a brick type carton formed from a continuous web of paperboard, it is not limited to such a carton construction; rather it is applicable to aseptic packages of generally brick type or parallelepiped geometrical form, whether formed from webs or individual blanks.
  • the numeral 10 denotes generally a brick type package fashioned from paperboard or other resilient, stiff and foldable material, the paperboard usually being coated with one or more layers of an impervious substance such as polyethylene. Aluminum foil and other resins are often employed.
  • Such brick type packs may be formed from a continuous web, the continuous web being suitably scored to facilitate its folding into the brick type form with subsequent filling and closing of the container, or from individual blanks.
  • Such containers have a seam running along three of the four side, top and bottom wall or panel portions.
  • FIG. 1 a second container, having a seam running along different wall panels than the container of FIG. 1 is illustrated in FIG. 5. It will be understood, however, that the manner of fashioning the brick type container and the location of the seam, if any, is not material for the practice of this invention.
  • the numeral 12 denotes the top wall or panel of the container, the top wall provided with a pour opening and seal assembly denoted generally by the numeral 14.
  • the numeral 12 denotes the top wall or panel of the container, the top wall provided with a pour opening and seal assembly denoted generally by the numeral 14.
  • the numeral 16 denotes one of the two side walls or panels, while the numeral 18 denotes the front wall or panel.
  • the numeral 22 of FIG. 1 denotes a seam running vertically and generally centrally of side wall 16, with triangular flap half or dog ear 24 extending downwardly along side panel 16 and affixed thereto as by a spot of a suitable adhesive.
  • the tab 24 carries seam portion 26.
  • Ear 24 is defined by a lateral continuation or extension of top wall 12 as well as a vertical continuation of side wall 16, the tab being folded into the illustrated triangular form in a manner which is conventional in the art.
  • the numeral 32 denotes a pour opening in the paperboard substrate 34 from which the carton is fashioned.
  • the opening may be die-cut or may be formed in any other convenient manner.
  • the numeral 36 denotes a peelable layer of polyester/foil/heat seal coating.
  • the numeral 34 denotes a layer of S.B.S. paperboard.
  • the interior of the carton corresponding to the lower portion of FIG. 2, includes layers 40, 42, 44 formed to surlyn/ foil/surlyn or low density polyethylene, respectively.
  • FIG. 3 The package 10, filled with, for example, fruit juice or milk or other liquid foodstuff, is grasped and peelable layer 36 removed. The remaining layers spanning aperture 32 are removed, as by rupturing or tearing, to thereby expose and open hole 32. This is illustrated at FIG. 3.
  • the contents of the container are partially dispensed.
  • the carton is now ready for storage until the next partial dispensing of the contents.
  • dog ear or triangular flap ear 24 is pulled away from its adhesive fastening to side wall 16, rotated approximately 270°, with the tip of ear 24 now being inserted into hole 32.
  • the resultant configuration of the container is illustrated at FIG. 4 and it will be observed that aperture 32 is very nearly closed, thereby inhibiting contamination of the contents of the container during storage.
  • the pour opening may be provided on the top of the carton, or on one of the sides, or be pcsitioned underneath one of the triangular flap ears at the top of the carton. In each case the opening is on any panel that does not have a fin seal. Moreover, the pour opening is so configured as to maximize its area of closure by the triangular flap ear. For example, as illustrated in FIG. 6, 7, and 8, the pour opening may be triangular, circular, or oval in shape.
  • U.S. Patent 1,437,511 to Gereke shows a folding carton with a die-cut tab that goes into a slot for reclosing. Pouring of the contents is accomplished by bowing the sidewall, creating a pour spout.
  • the present invention requires the puncturing of barrier laminations under a die-cut liquid pour opening or the removal of a barrier heat-sealed patches. The pour opening acts as the reclosure lock by snapping the pre-formed heat-seal extension (dog ear) into the trailing edge of the opening.
  • U.S. Patent 2,861,732 to Parker discloses a pre-scored pour spout similar to a milk container design.
  • the point of the spout snaps into a die-cut slot.
  • die-cut slots, spouts or extended flaps are not employed. Instead, pouring is accomplished through a die-cut opening that is covered by a barrier extrusion or coatings barrier sealed patches which eliminate the need to form a spout.
  • the only similarity to the prior art is that the point of the spout is held down by a slot in the-top panel.
  • U.S. Patent 2,946,496 to Stagmeier is similar to the Gereke patent in that it uses glue flaps, perforations, slots and tabs to develop an opening and reclosing feature. In this construction, glue is for sealing and perforations do not have to be torn away.
  • Patent 3,226,003 to Hickin is similar to the Stagmeier patent in that an opening and closing feature is created using normal folding carton techniques.
  • U.S. Patent 3,232,514 to Swede which discloses an aseptic package for liquids, also shows an opening and closing concept that uses perforations that must be torn. This type of tear opening is difficult to accomplish as a practical matter because the polymeric extrusion layers on the board do not tear easily.
  • the present invention is directed to a liquid impermeable carton for and of stiff resilient, and foldable material, such as paperboard, the carton being in the form of a rectangular parallelepiped having a front wall, a rear wall, two side walls, a bottom wall, a top wall, and a triangular flap ear at least at the top of one side wall edge and whose base is at the edge.
  • the triangular flap ear is normally folded and lies against a carton wall.
  • the improvement comprises a pour opening in a wall, the pour opening being adjacent to one side of the base of the triangular flap ear.
  • the pour opening is normally covered by a seal, which is opened upon initial partial dispensing of the container contents.
  • the container is adapted to be filled with a liquid foodstuff such as milk or fruit juice, whereby after rupturing the seal and dispensing a portion of the container contents, the triangular flap ear is bent, and its tip is inserted into the pour opening to inhibit contamination of the container contents.
  • a liquid foodstuff such as milk or fruit juice
