Abstract
A packaging container (1) formed of a flat sheet (2) cut and folded so as to form a flat quadrangular bottom (3) surrounded by two parallel vertical side walls (4, 5) and two vertical end walls (6) perpendicular to the side walls (4, 5), the homologous end portions (8, 8') of the latter being folded and fixed to each of said end walls (6), is described. In the container (1) of the invention, the two end portions (8, 8') are composed of an outer part (8e, 8'e), which can be fixed to the end wall, and of an inner part (8i, 8'i), separated from the outer part (8e, 9e) by a cut (10) with two perpendicular sides (A, B) and joined to it along an oblique fold line (C) about which it can pivot, said sides (A, B) of the cut (10) and said line (C) being arranged like the three sides of a rectangular trapezoid (T) whose base (D) is superimposed on or parallel to the fold line (Q) between an end wall (6) and the bottom (3).
Description
- The present invention relates to packaging containers usually used to hold fruit, vegetables and other types of foodstuffs.
- As is known, such containers are made by die-cutting, folding and fixing using adhesive or the like, so as to form a flat quadrangular bottom surrounded continuously, along its edges, by a pair of parallel vertical side walls and a pair of parallel vertical end walls, arranged perpendicularly, running on from one another.
- To achieve this, the end portion of each side wall is folded to form two triangles arranged symmetrically with respect to an oblique fold line, the outer triangle is adhesively bonded or otherwise fixed to an end wall, and then the various parts are pivoted so that the two triangles end up face to face and superimposed when all the walls are vertical.
- However, as will be seen more clearly below, such a method has a disadvantage, resulting from the fact that the end walls, partially covered by said two superimposed triangles of the side walls resting on them, have a central area where they are not covered by other layers of material (cardboard, corrugated cardboard, etc.) and are therefore rather weak and hence may deform during the transport and stacking of these containers.
- To overcome this disadvantage, the inventor of the subject of the present application has designed a new packaging container in which the abovementioned end portions of the side walls are composed of an outer part, which can be fixed to an end wall, and of an inner part, separated from the outer part by a cut with two perpendicular sides and joined to it along an oblique fold line about which it can pivot. Said sides of the cut and said fold line form a rectangular trapezoid whose base, when the container is assembled, is superimposed on or at least parallel to the fold line separating an end wall from the bottom.
- When the parts are folded to form the container, said outer parts of the end portions of the side walls occupy the abovementioned central area of the end walls, being superimposed on it, conferring on the whole greater rigidity and better mechanical strength.
- The subject of the present invention therefore consists of a packaging container as described in the attached
Claim 1. - A more detailed description of a preferred embodiment of the container of the invention will now be given, with reference to the attached drawings, in which:
- Fig. 1 is a partial perspective view of a packaging container made according to the current prior art;
- Fig. 2 is a plan view of a flat sheet with the cut and fold lines made so as to make it possible to form a container according to the invention;
- Fig. 3 is a partial plan view of the sheet of Fig. 2 with the side walls folded face down on the flat bottom;
- Fig. 4 is a partial perspective view of the container as it is being formed by folding and fixing its various parts;
- Fig. 5 is a partial perspective view of the container of Fig. 4 with all the walls in the vertical position, i.e. with the preparation work more or less finished.
- It can be seen from Figure 1 that, in a
packaging container 11 according to the prior art, the twoside walls bottom 13 have twoend portions 18, 18' which are folded along two fold lines, whose straight lines are marked s and t, which divide them into two triangles which are both only visible for the righthand side wall 15 and are marked 18'k and 18'h. - When the
container 11 is assembled, the outer triangle 18'h is fixed, generally by adhesive bonding, to anend wall 16, having a fold-downflap 16r of known type, and folding is carried out (arrow A) along the line s so as to superimpose the other, inner triangle 18'k on it. - The join between a side wall and the end wall leads to the situation depicted by the left
hand side wall 14, in which the abovementioned two triangles (of which only 18k, the inner triangle with respect to theside wall 14, is visible) are face to face and superimposed. The assembly is then immobilized in this position using known methods, folding down the abovementioned fold-downflap 16r which has projecting parts which engage in recesses made in thebottom 13 near the base of the end wall 16 (these projecting parts and recesses have not been shown in the drawing). - In a
container 11 thus formed, theend wall 16 has acentral area 16s over which no other layer or sheet of material is placed, giving rise to the disadvantages mentioned above relating to the relative weakness of thecontainer 11 in this area. - By contrast, Figure 2 shows a plan view of a
sheet 2 having cut lines (continuous) and fold lines (hatched) making it possible to use it to make a packaging container according to the invention. In thissheet 2 are made twoside walls end walls flaps flat bottom 3. Theside walls end portions inner part 8i, 9i, 8'i, 9' i, separated from anouter part 8e, 9e, 8'e, 9'e by acut 10 with two perpendicular sides A, B and joined to the outer part (being an extension of it) along an oblique fold line C about which the inner part can pivot.
Said sides A, B of thecut 10 and said fold line C, running on from one another, thus define the shape of a rectangular trapezoid T whose base D is superimposed on (but may also be simply parallel to) the fold line Q between anend wall bottom 3. - To give a clearer picture, Figure 3 shows the
sheet 2 with the twoside walls flat bottom 3. - Figure 3 shows how, in the preferred embodiment described, the maximum height H of each
side wall outer ends 8e, 8'e is substantially equal to half the width M of anend wall 6, such that, when the abovementioned parts are superimposed, they entirely cover the central area of theend wall 6, as can be seen in the drawing. - These
outer portions 8e, 8'e are then fixed by adhesive bonding to theend wall 6 so that when theside walls end wall 6 are brought into the vertical position the abovementionedinner parts 8i, 8'i, delimited by thecuts 10, pivot (arrow N) along said fold lines C (see Figure 4) and end up face down on theouter parts 8e, 8'e, superimposed on the latter. This final position is shown in Figure 5, where it can be seen that theend wall 6 is entirely covered by another layer in its central area, i.e. where it is more at risk of deforming during handling of thecontainer 1. As in the case described above, in the container of theinvention 1 too the various parts are fixed in the abovementioned position by folding down theflap 6r (visible in Figures 2, 3 and 5) and fixing it in the known way so as to clamp the end portions of the side walls, keeping them face down on and pressed against the end wall. - In practical terms, as can be seen in Figure 5, in a
container 1 according to the invention, only the inner parts oftrapezoidal shape 8i, 8'i of theend portions 8, 8' of theside walls outer parts 8e, 8'e, leaving only a relatively small trapezoidal area of theend wall 6 uncovered. - Thus is formed a packaging container which does not have the disadvantages of structural weakness mentioned several times. The inventor's object has thus been achieved.
- Obviously, a container according to the invention may also be made using parts shaped and sized in a different way to that described above and illustrated in the drawings.
- For example, the height of the outer parts of the end portions of the side walls, which are bonded to the end wall, may be other than half the width of the end wall, thus covering less of it, but in a way that is conducive to the desired result.
