Definitions

  • COMPARTMENTED CONTAHNER Food containers for prepackaged foods sold partially or fully prepared and frozen in freezer sections of food stores are normally provided with a partition which divides the container into compartments in which different types of food can be stored.
  • the partition is normally securely mounted to the bottom and side walls of the container. When it is so mounted, however, different foods cannot be mixed together in the container, thereby enabling the food to be consumed directly from the container.
  • Such a container must therefore be used instead as a serving bowl or tray, from which the food is placed onto a conventional plate.
  • Another disadvantage with such a construction is that when several empty containers are to be stacked for storage purposes, it is not possible to nest them, due to the partition wall; the containers must be stacked one on top of the other. A stack of containers formed in this way is unstable and requires an extensive vertical storage space.
  • the container of the present invention which is mainly characterized in that the bottom of the partition in the container is attached at the flat side to the bottom of the container, and can be folded along a line extending parallel with the bottom.
  • the partition can be torn from the bottom of the container,
  • the container of the invention thus permits storage of different kinds of food separately from each other, and if desired permits ready mixing of the separate foods in the container.
  • the container of the invention also can be nested in similar containers, and compactly stored therewithin.
  • FIG. 1 illustrates a blank for making a container provided with a collapsible partition wall in accordance with the invention
  • FIG. 2 illustrates the partition wall of the blank illus trated in FIG. I, seen from below;
  • FIG. 3 illustrates the blank shown in FIG. 1 after subsequent shaping to the container, with the partition wall collapsed;
  • FIG. 4 illustrates the container with the partition wall erected
  • FIG. 5 illustrates how the partition wall can be removed from the container
  • FIGS. 3, 4, and 5 the container is shown cut away, for better illustration.
  • FIG. 1 illustrates a blank from which a container acbossed fold lines along their borders.
  • the side walls of the blank at the corners have fold lines defining five abutting substantially triangular portions.
  • the blank can be readily folded to form the container along these fold lines.
  • a partition wall 9 is secured to the blank such as by bonding transversely across the bottom portion 2 from side wall 4 to side wall 6.
  • the partition wall which is also made of a thermoplastic polymer sheet, thermoplastic-coated cardboard sheet, or the like, comprises a foot 10, a web 11, and two side flaps I2, 13 having a slight arcuate edge, and a pull flap 14 (see also FIG. 2).
  • the'bottom surface of the foot 10 Prior to securing the partition wall 9 to the blank, the'bottom surface of the foot 10 is provided with two parallel score lines 15, 16, which extend from one short side of the foot to the other. The depth of the score lines is such that a readily tearable strip 17 is formed.
  • the foot 10 is then securely attached, such as by bonding, to the bottom portion 2 along the length of the strip 17.
  • the foot is attached in a manner such that the bond between the strip 17 and the bottom portion 2 is much stronger than the strength of the score-line weakened material from which the foot 10 is made, along the score line 15.
  • the partition wall 9 can be readily torn from the bottom piece along the scoreline 15.
  • the strip 17 remains attached to the bottom 2 when it is torn loose from the foot 10 and web 11.
  • the container, with the partition wall 9 securely bonded to the blank I, can be readily nested in similar containers, since the web it of the partition wall and the flaps 12, 13 are moved into flat parallel abutment with the bottom 2 when nesting one container in the other, and thereby require no more space than the thickness of the partition wall 9.
  • the blank is shaped to the container with partition wall 9 attached illustrated in FIG. 3 by folding the parallel side walls of the container, at the same time as cording to the invention is formed.
  • Theblank is made in one piece from a thermoplastic polymer sheet or the web Ill and the pull flap 14 remain in a recumbent position along the bottom portion 2 of the container. In this way, shaping of the container is not obstructed in any way by the partition wall, but can be effected irrespective thereof.
  • Another advantage afforded by the novel construction in this stage is that the containers can be readily nested within each other, since the side walls are flared slightly outwardly, and the partition wall folded flat down requires no more space than its thickness. The containers can therefore be nested within each other without being obstructed by the partition wall.
  • the partition wall 9 When the container is to be used, the partition wall 9 is raised, by folding the side flaps I2, 13 in a direction opposite to that in which they lay when shaping the container. (See FIGS. 3 and 4).
  • the side flaps attempt to return to their initial position, but they are prevented from doing so by the side walls 4, 6 of the container.
  • the side flaps are resiliently held against the side walls of the container with a force corresponding to the resiliency of the material of which the flaps are made.
  • the vertical edges of the side flaps are slightly arcuate in shape, and thus the side flaps conform substantially exactly to the slightly flared side walls of the container, so that a satisfactory seal is obtained between the side walls of the container and the partition wall.
  • the container be made from a thermoplastic polymer sheet, of thermoplastic-coated cardboard sheet. It can be made from any appropriate sheet material, such as for example, heat-resistant non thermoplastic material, aluminum, or cardboard or other sheet material coated with an appropriate, liquidimpermeable material, such-as for example, aluminum foil.
  • the partition wall can also be made from any of the aforementioned materials, which, however, need not be the same as that used for the container.
  • the container blank and the partition wall are made from a thermoplastic material or a thermoplasticcoated material, they canbe heat-sealed or bonded together.
  • the partition wall need not be provided with the pull flap illustrated in the exemplary embodiment.
  • a pull flap is practical and hygienic, since it provides a gripping point for the fingers without its being necessary for the fingers to come into contact with the food in the container. It is also possible to construct the pull flap so that it extends along the whole of the web 11 of the partition wall.
  • one edge of the side flaps of the partition wall is slightly arcuate in shape.
  • the side flaps may each have the shape of an equilateral triangle, or a square, or a rectangle.
  • an arcuate side flap is preferred, since this configuration facilitates the abutment of the side flaps with the side walls, and is better than if the side flaps were straight.
  • the container has been provided with only one partition wall. It will readily be perceived, however, that the container may, to advantage, be provided with several partition walls, and thereby with a correspondingly larger number of compartments.
  • the various compartments of the container need not, of course, be of equal size, but can be adjusted to the space desired for different foodstuffs to be stored in the container. It is possible to arrange the partition walls in the container so that one or more of said walls extend from a partition wall to another partition wall, or from a partition wall to one side walls of the container.
  • the partition wall be made from a cardboard material coated with a sealing material, it is not necessary to provide the foot 10 of the partition wall with two parallel score lines to facilitate tearing of the partition wall.
  • One score line will suffice, along the edge of the foot adjacent the web 11. The portion of the partition wall remaining when the wall is torn away is thus comprised of the strip of sealing material defined by the score line, and the three free edges of the foot 10.
  • a compartmented container having at least one bottom portion and upstanding side walls with corner portions therebetween attached to said bottom portion and defining an interior space therebetween; and at least one partition separating the space into at least two compartments, and comprising a foot, web and two side flaps, the foot being disposed at the bottom portion of the partition, at which foot the partition is attached to the bottom of the container, and each side flap being attached to opposite side edges of the web, the partition being pivotable along a fold line extending between the foot and the web, and the side flaps being pivotable along fold lines extending between the web and the side flaps, and resiliently resisting bending along the fold lines to frictionally engage abutting side walls of the container, and resist movement of the partition along its fold line between the foot and the web, the partition being pivotable along such fold line be tween an upright separating and compartmenting position, and an out-of-the-way flat position parallel to and abutting the bottom of the container; the corner portions between the container side walls being defined by fold lines into triangular portions
  • a container according to claim 1 in which the edges of the side flaps of the partition are arcuate in shape.
  • a container according to claim 1 in which the partition is provided with at least one score line along the side attached to the bottom of the container, whereby 9.
  • a blank for forming a container according to claim the partition can be torn from the bottom of the con- 1, made in one piece of sheet material with fold lines tainer. separating and defining the bottom and side wall por- 6.
