Definitions

  • the present invention relates to self-closing boxes, particularly though not necessarily of cardboard.
  • Certain snack and other foods cause a considerable amount of nuisance, in entertainment establishments and elsewhere, when they are discarded unfinished, because the remains can easily spill from their containers if they are not put tidily in refuse bins.
  • Popcorn for example, is a particular problem being light and readily spilt and also sticky with caramel, so that it readily soils carpets, etc in establishments such as cinemas.
  • the object of the present invention is to provide a self-closing box which can alleviate such problems.
  • a box of thin and resilient material and of generally polyhedral shape characterized in that it has an edge forming a closure line at which two faces constituting the closure faces meet separably such that pressing the vertexes at the ends of that line together splays those faces resiliently apart along that line to allow access to the interior of the box.
  • the box may conveniently be assembled from a flat blank of cardboard cut and creased to the appropriate shapes.
  • the two closure faces may initially be secured together by temporary securing means along their closure edges (the edges lying along the closure line).
  • a strip of adhesive tape which can be peeled off can be used; alternatively, the two faces may have extensions which are initially attached together. These extensions may be tied together by a tie through matching holes in them.
  • they may be defined by perforated lines so that they can be torn off the closure faces: in this case, they may be formed from a continuous portion of the card which is folded double to form a tab which protrudes beyond the two closure faces at the closure line, or may be formed separately on the two closure faces and glued together.
  • a further option for certain shapes of the box is a separate cap having the same shape as the top part of the box (ie the part around the closure line) and slightly larger than that part to fit snugly but removably over that part of the box.
  • closure edges of the two closure faces may simply abut at the closure line.
  • the closure faces may have an overlap.
  • the two closure faces both project in the same direction beyond the geometrically straight line between the two vertexes (ends) of the closure line, and come apart from the inside outwardly as the two vertexes are pressed together. This construction results in the two closure faces being distorted into slightly concave forms, with the tension resulting from the concavity tending to hold the closure edges together.
  • the box has a flat base with the closure line lying above and parallel to the base.
  • One suitable shape is a triangular prism, with one rectangular face forming the base of the box, the other two rectangular faces (side faces) forming the closure faces (so that the edge along which they meet, the edge opposite the base, forms the closure line), and the two triangular faces forming the ends of the box.
  • the two closure faces may have integral extensions to provide matching overlap; alternatively, this shape may be modified by adding a lune-shaped element to the top edge of each of the rectangular side faces to form a pair of closure faces with sliding overlap.
  • This shape can be modified by shortening the closure line so that the two closure faces become trapeziform.
  • the closure line can be extended, so that the two closure faces become trapeziform in the opposite orientation.
  • a second suitable shape has a rectangular base with, rising from it, four vertical sides with their top ends being sloped in zig-zag fashion, and closed by two sloping triangular top faces forming the closure faces with the closure line running between the two top-most points of the side faces.
  • the side faces may be trapeziform, or may have their top edges sloped right down to the base so that they are triangular. (Sloping them even further makes the two "top" faces trapeziform and the base hexagonal.)
  • the box may be such that it can be stored flat in partially assembled form.
  • the base may be of a construction which assembles automatically when such a partially assembled box is opened out.
  • Fig. 1 shows a blank of cardboard from which the first box may be made.
  • the cardboard must be stiff but resilient, and capable of being permanently folded along fold lines. (Obviously any thin or sheet-like material with these properties may be used.)
  • the box is assembled by creasing and folding the blank along the broken lines; all the folds are made in the same direction.
  • the sides of the box are formed by the two rectangles 17 and 18 and the two triangles 19 and 20; a tab 21 on triangle 20 is glued to the edge region 22 of rectangle 17 to hold the shape of the box.
  • the base is a rectangle which is assembled by folding together four flaps 10 to 13; flaps 11 and 13 are folded first, and then flaps 10 and 12 are folded together, with the tag forming part of flap 10 being inserted into the slot 14 in flap 12.
  • a box of the shape shown in Fig. 2A In this box, the two rectangular sides 17 and 18 form the closure faces.
  • the top edges 25A, 25B of these closure faces meet to form a single common closure line 25. If the top corners of the box at the ends of this edge 25 are pressed together manually, as shown by arrows 26 in Fig. 2B, the closure edges 25A, 25B are sprung or splayed apart, as shown by arrows 27, so allowing access to the interior of the box. If the pressure on the corners of the box is relaxed, the stiffness arid resilience of the cardboard will return the box to its closed state.
  • the box When the box has been partially assembled by gluing tag 21 to region 22 of side 17, it can be flattened by folding the sides 19 and 20 (together with the base flaps 11 and 13) along storage crease lines 30 and 31. A large number of boxes may then be stored compactly. For this, the base flaps 10 to 13 are left flat, ie not folded away from the planes of their associated sides 17, 19, 18, and 20 respectively. To complete the assembly of the box, the sides 19 and 20 (with their associated base flaps 11 and 13) are flattened out, and the base flaps are then folded together as described above.
  • the partially assembled boxes may be given a slight fold along the storage crease lines 30 and 31, and nested in each other to form a stack. This allows them to present a taper and to de-nest without jamming. If the stack is then be placed upside down, the top box in the stack can then be filled (eg with popcorn), the base assembled, and the completed and filled box removed from the stack, turned the right way up, and handed to a customer.
  • the top box in the stack can then be filled (eg with popcorn), the base assembled, and the completed and filled box removed from the stack, turned the right way up, and handed to a customer.
  • Fig. 3A shows a variant closure face shape for the box of Fig. 1.
  • the closure face 17 has its top edge 25A curved as shown; the other closure face 18 is similar.
  • the closure line of the box therefore becomes curved upwards above the geometrically straight line 25 shown in Fig. 2A, and the top parts of the closure faces 17 and 18 are in matching overlap when the box is closed.
  • the closure faces are forced into a slightly curved shape when the box is closed, with a positive pressure between their overlapping regions near their closure edges.
  • This variant form of the box like the other variants using the closure face shapes of Figs. 3B to 3E, may also be desirable as having a more distinctive appearance.
  • a hole 26 may be provided near the top edge of the face 17, and a corresponding hole in the face 18.
  • a ribbon or string can then be tied through the two holes to form temporary securing means, which can be untied when access to the box is required.
  • Fig. 3B shows a variant which is similar to the Fig. 3A variant.
  • the closure face 17 has a straight crease 31 across it, which is folded slightly backwards. The overlapping portions of the closure faces 17 and 18 then lie against each other, but without forcing the main portions of those faces out of flat.
  • Fig. 3C shows a variant which is similar to the Fig. 3B variant.
  • the closure face 17 has a crease 32 across it which is curved oppositely to the top edge 25A.
  • the main use of this is with the Fig. 4 shape described below.
  • Figs. 3D and 3E show further variants of the box of Fig. 1, in which the sides 17 and 18 are trapeziums. This results in the shape of the box being that of a horizontal triangular prism with sloping ends. If the Fig. 3E shape is suitably chosen to match that of the triangular ends, the blank from which the box is made may be straight (ie with the creases between the sides of the box and various flaps forming the base being a straight line).
  • Fig. 4 shows a further variant of the box of Fig. 1.
  • the closure faces 17 and 18 are of the form shown in Fig. 3C, but the fold 31 is initially made in the same sense as the other folds.
  • the portions 17A and 18A of the faces 17 and 18 are therefore roughly horizontal, forming inwardly facing overlapping lune shapes on those faces. (This also forces the faces 17 and 18 to be slightly curvilinear.)
  • the result is a shape of the "pillow-pack" type, which retains its contents with considerable tenacity; in effect, the lune shapes 17A and 18A in effect form temporary initial closure means.
  • these portions 17A and 18A have to be pulled out to form smooth extensions of the faces 17 and 18.
  • the box thereupon becomes in effect the Fig. 3C type box.
  • this variant can be combined with the variants of Figs. 3D or 3E.
  • Fig. 5 shows a second form of box, which is based on a vertical square prism.
  • This box has a base 30 and four vertical sides 31-34, each vertical side being in the form of a rectangle with the top end sloped off to turn it into a trapezium.
  • the box is closed by two sloping triangular faces 35 and 36 at the top; these two faces form the closure faces, and their common edge 37 forms the closure line of the box.
  • This box is assembled from the blank shown in Fig. 5A. All tabs for gluing are shown in Fig. 5A; some are shown, in lightly broken lines, in Fig. 5.
  • Fig. 5A which is a blank for this box, shows this strip as a double strip which is joined to the faces 35 and 36 and has a crease line 39 along its centre.
  • this strip 38 is folded double along the line 39. Its joins to the faces 35 and 36 are defined by lines of perforation, as shown at 37, which will form the closure edges of the faces 35 and 36.
  • the strip 38 When the box is first assembled, it is therefore sealed by the strip 38, which forms a temporary seal. To gain access to the box, the strip 38 has to be torn off.
  • the box can then be opened along its closure line 37 by pressing the corners at the ends of this line together, and will close again when this pressure is removed. If the box of Fig. 5 is made without the sealing strip 38, then it can be made from a "straight" blank in which the four main sides 31-34 form a straight band.
  • an alternative temporary initial closure means can be used in the form of a large cap having the same shape as the upper part of the box and fitting snugly over the upper part of the box.
  • Fig. 6 shows a box whose shape is a variant of that of Fig. 5, in which the triangular closure faces 35 and 36 extend down to the base 30. As a result, the side faces 31-34 are triangular. (For convenience, the tabs and the temporary sealing strip are omitted in Fig. 6.)
  • the shape of this second box can also be varied in other ways, eg analogously to Figs. 3D and 3E.
  • Fig. 6A shows a blank for this box. This shape can be partially assembled and stored flat with only the base remaining to be assembled for final assembly.
  • Fig. 5 cannot be treated in the same way, because when the three faces 31, 32, and 35 are joined they form a 3-dimensional shape which cannot be flattened. However, for some purposes it may be acceptable to partially assemble the shape of Fig. 5 is a flattenable form, leaving the joins between faces 31 and 32, and between 33 and 34, unmade.
  • the temporary sealing strip can be formed with a straight central crease and curved lines of perforation. Alternatively, it can be formed in another way, eg by gluing together two portions, one attached to each of the closure faces.
  • the technique of Fig. 4 can also be used with boxes of the shapes of Figs. 5 and 6, though that would require the omission of the sealing strip, If desired, a strip of removable adhesive tape can be used to provide a temporary seal for the box.
  • Fig. 7 which is a box of the Fig. 1 type as modified by combining Figs. 3B and 3D
  • Fig. 7A is a blank for this box. This consists of four faces 41-44, with a flap 45 which has to be glued to the outer end of face 44, plus base parts 46-53.
  • the base parts consist of two main flaps 46 and 50, plus various minor flaps and portions 47-49 and 51-53. The two portions 47 are glued together, and the two portions 51 are glued together.
  • the box When the box has been partially assembled by the gluings just noted, it can then be stored flat, with 180° bends down the centre lines of the end faces 42 and 44, and with the base flaps all tucked up inside the box. .
  • the assembly of the box When the assembly of the box is to be completed, it is opened out by pulling the sides 41-44 apart. This pulls the base flap portions down from inside the box.
  • the lowermost parts of the main flaps 46 and 50 form two tongues which automatically engage with each other (each sliding over the adjacent part of the other flap), to form a firm and secure base.
  • Figs. 8 and 8A show a box and a blank therefor of the same general shape as the Fig. 5 box but which is assembled in a different manner.
  • This box has sides 55-58, top closure faces 58 and 59, and a base 60.
  • This box can be stored flat in partially assembled form, with only tongue and groove matching required for completing its assembly.
