[0001] The present invention relates to a stackable container for holding paper or the like.
[0002] It is known to produce paper-holding trays, also called in/out trays, so that they
can be stacked on top of one another on the working surface. Various systems, see
eg. DE-U-8504841, generally of the snap-together type, have also been proposed for
stacking the trays so that they cannot be easily separated.
[0003] A conventional tray, for example, has a tooth formed on the lower outer side of each
side wall of the tray and is suitable for entering a corresponding slot formed on
the upper inner edge of the respective side wall of the underlying tray.
[0004] The advantages which arise from having anchored trays are apparent, and several commercially
available trays provide this feature. However, the trays are made of plastics and
are very thin for greater lightness, therefore, when loaded with heavy objects or
simply while being handled, the trays have a tendency to flex. This flexing can easily
cause the disengagement of the trays from one another.
[0005] One aim of the present invention is to provide an item-holding container or tray
with a coupling system which is absolutely safe and capable of withstanding the greatest
weights.
[0006] Within the scope of this aim, an object of the invention is to provide a container
which allows the rapid and easy coupling of one container to another.
[0007] Another object of the invention is to provide a container which has a simple structure
and can be obtained easily from the point of view of production.
[0008] This aim, these objects and others, which will become apparent to those skilled in
the art, are achieved by a stackable container for holding paper or the like, comprising
at least one bottom, a right side and a left side, each of said sides comprising an
outer upper edge, an inner upper edge, an outer lower edge and an inner lower edge,
characterized in that it comprises: a slot shaped as inverted T and formed on said
inner upper edge of each of said sides; a horizontal tooth formed on said inner lower
edge of each of said sides, said horizontal tooth being directed outward and being
adapted to engage said slot of a second container arranged below said container, locking
means formed on said outer lower edge of each of said sides, said locking means being
adapted to cooperate with said outer upper edge of each of said sides of said second
container, so as to prevent said horizontal tooth from disengaging from said slot
substantially in a direction which is orthogonal to the extension of said slot.
[0009] Further characteristics and advantages of the invention will become apparent from
a reading of the detailed description of a preferred but not exclusive embodiment
of a container according to the invention, illustrated only by way of a non-limiting
example in the accompanying drawings, wherein:
Figure 1 is a top perspective view of a container according to the invention;
Figure 2 is a perspective view of the anchoring plate fixed to the lower face of a
surface;
Figure 3 is a transverse sectional detail view of the coupling system according to
the invention;
Figure 4 is a schematic perspective view of a plurality of stacked containers.
[0010] With reference to the above figures, the container according to the invention, generally
designated by the reference numeral 1, comprises a bottom 3, a left side 5, a right
side 7 and a rear side 9.
[0011] Each side comprises an inner upper edge 11, an outer upper edge 13, an inner lower
edge 15, and an outer lower edge 17.
[0012] The inner upper edge of each side comprises a slot 19 which is shaped as an inverted
T and lies longitudinally along said edge so that the central stem of the T is open
onto the upper face of the same side of the structure.
[0013] The inner lower edge 15 of each side of the structure has a horizontal tooth 21 which
is directed outward and is adapted to engage the slot 19 of the respective side of
a second underlying container to be coupled to the container.
[0014] The outer lower edge 17 of each side of the container has a locking means which,
in the illustrated embodiment, is constituted by a pair of vertical teeth 23. The
vertical teeth 23 are adapted to cooperate with the respective outer upper edge of
the second container to be coupled below.
[0015] In order to couple the first container to the second underlying container it is sufficient
to mate the horizontal teeth of the first container with the upper opening of the
respective slots of the second container and make an L-shaped movement.
[0016] As shown in Figure 3, in the coupled condition, the vertical teeth 23 of the first
container abut with the outer upper edge of the second container, so that even in
case of a considerable flexing of the bottom 3 of the first container the horizontal
tooth 21 cannot leave the slot 19 in a horizontal direction.
[0017] The container according to the invention also comprises an anchoring plate 25, as
shown in Figure 2, which is adapted to be fixed to the lower surface 27 of a working
surface 29, such as desk, for example.
[0018] The anchoring plate 25 comprises a left edge 31 and a right edge 33, and each edge
comprises a horizontal tooth 35 and a pair of vertical teeth 37.
[0019] Once the plate 25 has been fixed to the working surface, it is sufficient to move
the container 1 to be coupled with an inverted L-shaped movement in order to fix it
to the plate. It is also possible to couple several other containers by stacking them
one below the other.
[0020] It has been observed in practice that the invention achieves the intended aim and
objects by providing a stackable container which is constructively very simple and
at the same time resistant to the most intense stresses.
[0021] The coupling system is so safe that it allows to couple the containers below one
another, hanging for example under the desk, with no risk that they may disengage.
[0022] The container according to the invention is susceptible to numerous modifications
and variations, all of which are within the scope of the claims.
[0023] In practice, the materials employed, as well as the dimensions, may be any according
to the requirements.
[0024] Where technical features mentioned in any claim are followed by reference signs,
those reference signs have been included for the sole purpose of increasing the intelligibility
of the claims and accordingly, such reference signs do not have any limiting effect
on the scope of each element identified by way of example by such reference signs.
