Definitions

  • This invention' relates to a box.
  • the invention is directed to a box especially adapted for packaging foods which should be protected against loss of moisture and aroma.
  • Boxes having bottom and side walls formed of one uncut piece of material are well known, the corners being constructed by triangular pleats which are folded against the side walls. This manner of folding the corners usually leaves but one, and at the most, two thicknesses of material at the corner edge. The lack of adequate corner reinforcement is especially serious when the box is formed of light weight material such as paper or metal foil.
  • Figure 2 is an enlarged plan View of a corner of the box with the pleats partly folded;
  • Figure 3 is an enlarged exaggerated plan view of the box with the pleats fully folded
  • Fig 5 is an enlarged exaggerated plan view of a box corner constructed from the blank of Figure 4;
  • Figure 6 is a cross-sectional view through an open box
  • Figure '7 is a perspective view, partly in seotion, of the box with the lid in place, and before sealing;
  • Figure 8 is an'enlarged fragmentary view, in section, of the lid sealed in place
  • Figure 9 is a perspective view, partly in section, of the box with a modified lid
  • the box blank of Figure 1 is composed of a bottom panel 2 and four side panels 4, 6, 8 and ill, the blank being adapted to be folded as indicated by the dashed lines. Each corner is divided into six panels separated by fold lines. Panels I2 and i4 form one pleat, panels it and 8 a second, and panels 20 and 22 a third.
  • the fold line between panels It and It has a length equal to the width of side panel 6, or the height of a box side, and the corner of the blank is cut off at right angles to the fold lines between panels I41 and I6, and I8 and 20, respectively, so that all the panels are right angle triangles.
  • the blank has a peripherally extending margin portion 23 delineated by the fold line 24.
  • FIGS 2 and 3 The manner of folding the corners is shown in Figures 2 and 3.
  • corner panels I2 and M are folded into a pleat with panel I2 lying against the inside face of panel 4.
  • Panels l6 and I8 form a pleat lying against the inside face of side panel [0.
  • Panels 20 and 22 fold into a pleat which takes a position within the fold between panels l2 and 14.
  • the exterior of the box presents clean unbroken surface panels, and the corner edge is reinforced by being built up of three thicknesses of material adjacent panel is and five thicknesses of material adjacent panel 4.
  • a stiilening liner is placed in the box.
  • the liner is shown composed of two strips of material 26 and 28 laid cross-wise of each other over the bottom of the box, and extending up the respective side walls Of the box, with their upper edges flush with the upper edges of the box sides.
  • the box is adapted to be filled when in this completely opened condition.
  • the upper margin portions 39 and 32 of liners 2E and 28- are bent inwardly and horizontally to form a ledge upon which the lid can rest.
  • This additional liner can be constructed as described for the blanks of Figures 1 and l, and made of waterproof and/or insulating material.
  • the margin portion is torn off or cut away, thus freeing the lid. If this is done only on three sides, the fourth side can serve as a hinge.
  • a modified lid is constructed as the lid in Figure '7, with the addition in that the material 34 is provided with flaps 46 which are folded fiat against the bottom of the lid when the lid is first placed on the box. After the sealing margins 23 and 38 have been cut away, and the lid lifted, the flaps ii! are bent downward and serve to keep the lid in place when it is again lowered onto the box.
  • the further modified lid has one of the flanges it permanently folded fiat against the underface of the lid, and provided with integral arms 32.
  • An aperture, or window, is cut in the lid and covered by a sheet of transparent material 44 held in place by arms a2.
  • the lid is glued to margin 23 which acts as a hinge.
  • a box constructed as described can be sealed to be substantially damp proof, and. prevent the escape of aromas.
  • the novel corner construction makes a rugged box well adapted to withstand the strains of packing and shipping.
  • each corner between a side wall panel and the adjacent end wall panel comprising a plurality of an odd number of pleats integral with the material of the side and end wall panels, at least one of said pleats lying folded against a side wall panel and at least one other pleat lying folded against an end wall panel, and another of said odd number of pleats lying inside the fold of one of the pleats folded against one of said Wall panels.
  • a container as in claim 2 further comprising a pleat adjoined to one wall panel lying against the adjoined panel and enclosing the pleat adjoined to the other side wall panel, and an intermediate pleat lying folded against said other side wall panel.
  • each corner further comprising six panels formed into three pleats, and the two center corner panels having apex angles larger than those of the adjacent corner panels.
