[0001] The present invention relates to a storage box, comprising stacking tabs that can
be placed in a position of use or in a hidden position.
Background of the invention
[0002] Boxes are known that are used to store objects. These boxes are normally made of
cardboard and are normally formed from a sheet provided with a number of folding lines,
in such a way that by means of an assembly process the box is obtained and is ready
for use.
[0003] Stackable storage boxes usually comprise stacking tabs protruding from the box, which
allow one or more boxes to be stacked together as said stacking tabs are housed in
corresponding stacking slots located in the other box with which it is intended to
stack. Usually each model has both stacking tabs and stacking slots, thus each box
is a modular element that can be combined with other identical or similar compatible
boxes.
[0004] In conventional storage boxes these stacking tabs are fixed, that is, they always
protrude from the box, regardless of whether they are used or not. However, the permanent
presence of the stacking tabs protruding from the box has the drawback that they can
be accidentally damaged, so that when they are used, they may not be effective to
allowing the stacking.
[0005] Therefore, an objective of the present invention is to provide a storage box that
allows the use of the stacking tabs only when necessary, not protruding from the box
when they are not intended to be used.
Disclosure of the invention
[0006] With the storage box of the invention said disadvantages are solved, presenting other
advantages that will be described below.
[0007] The storage box according to the present invention is formed from a sheet, which
is preferably of corrugated material, said corrugated material defining a plurality
of channels parallel to each other, said box comprising side walls and a bottom, in
which at least one of the side walls comprises a stacking tab, and it is characterized
in that said stacking tab is mounted on a flap hinged to said at least one side wall
and said stacking tab is movable between a position of use, in which it protrudes
through a mounting slot located next to a folding line that delimits said at least
one side wall, and a hidden position, in which it does not protrude from the body
of the box.
[0008] This way, the stacking tab or tabs can be placed in their use position only when
they are to be used, without accidentally damaging them when not in use.
[0009] Advantageously, the storage box also has stacking slots, which serve to house the
stacking tabs of another box that is the same or compatible so that the boxes are
one on top of the other. This way, the two or more boxes stacked with each other are
held allowing a more stable stacking, preventing the boxes from moving to each other.
[0010] Advantageously, two opposite side walls comprise said stacking flange and said stacking
slot.
[0011] Furthermore, said stacking flange is advantageously mounted on said flap in an articulated
manner, said stacking flange being able to be mounted on a middle portion of said
flap or at one end of said flap.
[0012] According to a preferred embodiment, said flap can comprise a projection that, in
the hidden position of the stacking flange, is housed in said mounting slot of the
side wall, in which case said stacking flange preferably comprises a cut-out area
for forming said projection.
[0013] In one embodiment, said flap may be hinged to said at least one side wall along a
folding line inclined with respect to the bottom of the box.
[0014] In another embodiment, said flap can be hinged from a middle portion of said side
wall, said stacking flange being hinged from said flap, so that in its hidden position
it forms part of the side wall and in its uncovered position it is housed in said
mounting slot.

Description of a preferred embodiment
[0016] Firstly, it is indicated that the box according to the present invention is formed
from a single sheet of material, preferably a corrugated material, such as corrugated
cardboard, defining a plurality of channels substantially parallel to each other.
[0017] The box of the present invention may be used for storage of products, i.e., it requires
strength characteristics to prevent the products from being damaged during the use
of the box, which is also stackable.
[0018] A first embodiment of the box according to the present invention is shown in Figures
1 to 3.
[0019] According to this first embodiment, the box is formed from a corrugated cardboard
sheet that, in its mounting position, defines side walls 1 and a bottom 2. In the
shown embodiment, the side walls 1 are three, and an upper part 9 is also present,
so that a front opening is defined for access to the box.
[0020] In this position of use shown in the figures, the corrugated cardboard channels are
arranged vertically or inclined, to provide adequate resistance to stacking.
[0021] According to this embodiment, two flaps 4 extend from two opposite side walls 1,
which in the position of use are placed on the internal part of the side walls 1,
as can be seen in figure 3.
[0022] Furthermore, these flaps 4 also comprise reinforcing tabs 10, which are placed in
contact with the other side wall 1 to reinforce the resistance to stacking. These
reinforcing tabs 10 comprise projections 11 that keep each flap 4 slightly separated
from the corresponding side wall 1.
[0023] Each of these flaps 4 further comprises a stacking tab 3, which is hinged with respect
to the flap 4, and which can be placed in a position of use or in a hidden position,
as will be explained below.
[0024] It is precisely in the space between the flap 4 and the side wall 1 that we have
previously mentioned where the stacking tabs 3 are housed in their position of use;
both those of the box itself and those of the same or compatible box that is stacked
with the first one. The stacking tabs 3 of a box are housed in the space between the
two surfaces of another similar or compatible box when inserted through stacking slots
5.2 conveniently located at the bottom of the box.
[0025] This stacking tab 3 is preferably arranged in a middle position near the top of the
flap, according to the shown position of use, and it is hinged with respect to a substantially
horizontal folding line, so that it can be placed in a position vertically down (figure
3, upper box) or in a vertical up position (figure 3, lower box).
[0026] In figure 2 it can be seen how the stacking tab 3 is placed in its upright position,
or use position, protruding through a mounting slot 5 located in the upper part 9
next to the upper edge of the corresponding side wall 1.
[0027] In order to place the stacking tab 3 in its position of use, firstly, the flaps 4
are folded into the box, and then the stacking tabs 3 are folded upwardly, entering
the mounting slots 5.
[0028] In figure 3 two boxes of the invention according to this first embodiment are shown.
The upper box is with the stacking tabs 3 in their hidden position, while the stacking
tabs 3 are in their use position, allowing the upper box to be stacked using the stacking
slots 5.2.
[0029] In figures 4 to 8 a second embodiment of the box according to the present invention
is shown.
[0030] For simplicity and clarity reasons, the same reference numbers are used to identify
the same components of the box that in the previous embodiment. In addition, only
the differences with respect to the first embodiment previously disclosed are described
for the sake of simplicity.
[0031] The main difference of this second embodiment is the position of the stacking tabs
3, which are arranged at the end of the flaps 4, and are oriented downwardly, so that
in their position of use they protrude from the lower portion of the box.
[0032] As can be seen in figure 4, the flaps 4 have a shape defined by two portions, a proximal
portion that is extended in a hinged way from an inclined folding line 8 of the front
of the box, and a distal portion provided with the stacking tab 3 at its end.
[0033] Said stacking tab 3 forms a cut-out area 7, defining a projection 6, which is housed
in the mounting slot 5 of the box in the hidden position of the stacking tab 3, as
will be described below. In this embodiment, the mounting slot 5 is located at the
bottom 2.
[0034] The box of this second embodiment also comprises a frontal flap 12 provided with
a longitudinal folding line 13 that divides it in two, so that, in its use position,
it forms a double-thickness front wall, as shown in figure 8, with reinforcing plates
16. For fastening, this frontal flap 12 comprises projections 14 that are housed in
complementary slots 15 arranged on the frontal edge of the bottom 2.
[0035] For the placement of the stacking tabs 3 in their position of use, the flaps 4 are
folded towards the inside of the box (figure 5), the stacking tabs 3 being inserted
in the mounting slots 5 in the side edges of the bottom 2 of the box (figure 6), the
stacking tabs 3 protruding on the lower portion for their coupling with a lower box,
with is the same as the first one or compatible with the first one, which has corresponding
stacking slots 5.2 located on the side edges of the upper part 9.
[0036] For the placement of the stacking tabs 3 in their hidden position, the flaps 4 are
also folded towards the inside of the box (figure 5), the projections 6 being inserted
in the mounting slots 5 in the side edges of the bottom 2 of the box (figure 7), locking
the flaps 4 in their position substantially in contact with the side walls 1.
[0037] In figure 8 two boxes according to this second embodiment are shown, with the stacking
tabs 3 in their use position in the upper box and in their hidden position in the
lower box.
[0038] In figures 9 and 10 a third embodiment of the box according to the present invention
is shown.
[0039] For simplicity and clarity reasons, the same reference numbers are used to identify
the same components of the box that in the previous embodiment. In addition, only
the differences with respect to the first embodiment previously disclosed are described
for the sake of simplicity.
[0040] The main difference of this third embodiment with respect to the first embodiment
is that the flaps 4 are hinged from a middle portion of said side wall 1, said stacking
tabs 3 being arranged at the end of the flaps 4.
[0041] To place the stacking tab 3 in its position of use, firstly, the flaps 4 are folded
upwardly, as shown in the detail of figure 10, and then the stacking tabs 3 are folded
upwardly, being inserted inside the mounting slots 5.
[0042] Although reference has been made to specific embodiments of the invention, it is
