DETAILED DESCRIPTION OF AT LEAST ONE EMBODIMENT

[0038] The present invention relates to a container for the storage of a plurality of windows for household appliances which, with reference to FIGS. 2a to 8, has been generally indicated by the number 1.

[0039] In FIGS. 2a, 3, 4, 5 the contour line of the flap and/or secondary opening of the bottom of the container has been made visible with a broken line at the portions in which it should be invisible as it is hidden by other elements of the respective container.

[0040] Any modifications or variants which, in the light of the description, are evident to the person skilled in the art, must be considered to fall within the scope of protection established by the present invention, according to considerations of technical equivalence.

[0041] In the present detailed description, reference is substantially made to windows for household appliances which have a projecting portion surrounded by a perimeter flange such as, for example, portholes for a washing machine, a dryer or a washer-dryer.

[0042] Generally, windows for household appliances 50 (and in particular portholes) have a substantially flat perimeter portion enveloping a central portion along an extension axis orthogonal to the lying plane of the perimeter portion. More precisely, the projecting central portion can have different configurations, e.g. it may be conformed like a substantially semi-spherical cap, like a truncated cone shaped cap, or like a projecting cap with a substantially central concave depression.

[0043] The perimeter portion can also have different perimeter extensions. In fact, it can have a circular, square, triangular or D shape, or irregular variants thereof.

[0044] FIG. 2a shows a container 1 for the storage of a plurality of windows for household appliances 50 which comprises a side wall 2 for laterally delimiting, about a piling direction L, a containment volume V for containing the plurality of windows for household appliances 50. In particular, the container 1 has a main opening configured to enable the insertion and piling of each window for household appliances 50 in the containment volume V and, additionally, a bottom 4 configured to define a support surface 5 for at least one perimeter portion 51 of a window for household appliances. The side wall 2 is preferably interposed between the bottom 4 and the main opening 3.

[0045] Preferably, the bottom 4 has a secondary opening 6 substantially afforded in a central position with respect to the support surface 5 so as to be able to be crossed by a projecting portion 52 (or cap) of a window for household appliances 50 arranged outside the container 1.

[0046] In particular, the bottom 4 has an own flap 7 movable between a first closing position, wherein the flap 7 itself closes at least partially the secondary opening 6, and a second opening position, wherein the flap 7 itself is distanced from the bottom 4 for leaving the secondary opening 6 at least partly open.

[0047] In other words, the container 1 is configured to contain a plurality of windows for household appliances 50 piled along a piling direction L coinciding with the extension direction of the side wall 2 of the container 1 itself.

[0048] The main opening 3 enables an operator to insert each window for household appliances 50 into the containment volume household appliances, one at a time, directly piling them into the container 1 or all together already piled.

[0049] The bottom 4 which is opposite the main opening 3, defines the support surface 5 for supporting the pile of windows for household appliances 50. More precisely, the bottom 4 is conformed so that at least the perimeter portion 51 of the first window for household appliances 50 of the pile abuts on the support surface 50. In other words, the first window for household appliances is in direct contact with the support surface 5 of the bottom 4 on which it discharges its own weight and the weight of the remaining windows for household appliances 50 piled on top. Consequently, the projecting portion 52 of each window for household appliances extends along the piling direction L towards and beyond the main opening 3.

[0050] Advantageously, the bottom 4 comprises a flap 7 arranged at a central portion of the bottom 4 itself, substantially encircled by the support surface 5 at the convex portion 52 of the windows for household appliances 50.

[0051] Even more advantageously, the aforesaid flap 7 is movable between the first closing position, in which it is coplanar with the support surface 5 so that the bottom 4 is substantially flat, and the second opening position, in which the flap 7 is inclined with respect to the support surface 5 so as to open an access window, i.e. the secondary opening 6, useful to enable the passage of the projecting portion 52 of a window for household appliances 50 contained in a further container 1.

[0052] In this way, when two containers 1 are stacked onto one another along the piling direction L, the projecting portion 52 of the last window for household appliances 50 of the pile of the container 1 arranged below is able to move from the first closing position to the second opening position the flap 7 of the container 1 arranged above so that the flap 7 itself is interposed between the two piles of windows for household appliances 50 defining a shock absorbing layer against impacts and vibrations.

[0053] Preferably, the flap 7 is afforded by a notch in the bottom 4 of the container 1.

[0054] In fact, generally, between the windows for household appliances of the same pile a layer of paper or cardboard is interposed, which is useful for cushioning the vibrations due to transport that could chip and/or ruin the windows for household appliances as they are made of glass.

[0055] Even more preferably, the flap 7 is at least partially connected to the bottom 4 at a connection portion 9 from which it extends to a central zone 15 of the secondary opening 6 so as to cover at least part of the top of the projecting portion of the window of the household appliance during the piling of the container 1 itself. The central zone 15 is substantially the surface portion arranged around the intersection between the lying plane of the flap 7 (when in the first closing position) which virtually closes the secondary opening 6 and the axis orthogonal thereto in which the radii intersect (if the secondary opening 6 is circular/oval shaped) or the bisecting lines of the secondary opening 6 (if the latter is, respectively, circular/oval shaped or polygonal).

[0056] In this way, the flap 7 is easily movable between the first closing position and the second closing position and, furthermore, during the stacking of various containers onto one another it remains advantageously interposed between the two different piles of windows for household appliances 50.

[0057] Additionally, advantageously, the flap 7 has a surface extension such as to guarantee the overlapping with at least a central zone 15 of the secondary opening 6, at least when the flap 7 is arranged in the first closing position.

[0058] In this way, when a first container 1 is piled above a second container 1 the flap 7 is sufficiently large to be able to be interposed between a first window for household appliances 50 of the pile of the first container 1 and a last window for household appliances 50 of the pile of the second container 1, in particular between the projecting portions of the windows for household appliances 50 (concave side of one and convex side of the other). Advantageously, therefore, the flap 7 defines a separating layer between the windows for household appliances 50 arranged in different containers 1. Therefore, the flap 7 is able to absorb any impacts and prevent any direct friction between the windows for household appliances 50 which could cause aesthetic and/or structural defects.

[0059] According to one aspect of the invention (not illustrated), the flap 7 extends from the connection portion 9 to an edge of the secondary opening 6 arranged on the opposite side to the connection portion 9.

[0060] In this way, the flap 7 substantially defines a strip that crosses the secondary opening 6 from one side to the other, through the central zone 15 of the latter.

[0061] According to another aspect of the invention, the flap 7 has a surface area equal to at least half that of the secondary opening (6).

[0062] According to a further aspect of the invention, the flap 7 has a surface area substantially equivalent to that of the secondary opening 6.

[0063] In this way, a larger surface area of the flap 7 corresponds to a larger area of the bearing that can be interposed between the windows for household appliances 50 piled onto one another.

[0064] Preferably, the flap 7 is at least partially counter shaped with respect to the secondary opening 6 so as to overlap with at least the central zone 15 of the secondary opening 6 itself.

[0065] Even more preferably, the flap 7 is counter shaped with respect to the secondary opening 6 so as to close it completely at least in the first closing position.

[0066] In this way, when it is in the first closing position, the flap 7 is able to completely close the secondary opening 6.

[0067] FIG. 3 shows a first embodiment of the container 1 for the storage of a plurality of windows for household appliances 50, wherein the flap 7 and the secondary opening 6 have a substantially D-shaped configuration.

[0068] FIG. 4 shows a second embodiment of the container 1 for the storage of a plurality of windows for household appliances 50, wherein the flap 7 comprises a plurality of segments 8 arranged flanked to one another along a closed trajectory C, preferably circular, which defines a perimeter of the secondary opening 6. In particular, the segments 8 are connected to one another through a connection portion 9 which is central with respect to the closed trajectory C. Additionally, at least one of the segments 8 is connected to the support surface 5.

[0069] In this way, the segment 8 connected to the support surface 5 defines the fulcrum for the movement between the first closing position and the second opening position, whereas the remaining segments 8, separated from one another except for the central connection portion 9, are able to bend in order to adapt to the shape of the windows for household appliances 50.

[0070] Preferably, the flap 7 and the secondary opening 6 have a substantially circular conformation.

[0071] Even more preferably, the segments 8 have the same substantially triangular conformation.

[0072] FIG. 5 shows a third embodiment of the container 1 for the storage of a plurality of windows for household appliances 50. More precisely, the container 1 comprises a plurality of flaps 7 each of which is shaped like a segment. In particular, the flaps 7 are arranged flanked to one another along a closed trajectory C, preferably circular, which defines a perimeter of the secondary opening 6. Additionally, each of the flaps 7 is connected to a respective portion of the support surface 5 and, furthermore, the flaps 7 themselves are separated from one another.

[0073] In other words, part of the bottom 4 has a series of spoke-shaped notches which define the plurality of substantially segment-shaped flaps 7. In this way, the convex portion 52 of the window for household appliances 50 which crosses the secondary opening 6 is able to bend each flap 7 which will remain interposed with the inside of the convex portion 52 of the window for household appliances arranged in the container 1 of which the flaps 7 are a part.

[0074] Preferably, each of the segment-shaped flaps 7 has the same conformation as the others. Even more preferably, such conformation is substantially triangular.

[0075] FIG. 6 shows a fourth embodiment of the container 1 alternative to that illustrated in FIG. 4. More precisely, FIG. 6 shows a plurality of triangular flaps but of different shapes. In other words, the centre of the spoke-shaped notches afforded on the central portion of the bottom 4 is not centred but shifted towards one of the partitions of the side wall 2.

[0076] Preferably, according to a possible aspect of the invention, each flap 7 can be detached from the bottom 4.

[0077] In this way, advantageously, each flap 7 can be separated from the bottom 4, e.g. when two containers 1 are piled onto one another, for remaining interposed between two windows for household appliances 50 and defining an absorption layer against impacts and/or friction.

[0078] According to an aspect of the invention, the side wall 2 defines a substantially rectangular perimeter for said containment volume V.

[0079] Even more preferably, the side wall 2 defines a square perimeter for containing the pile of windows for household appliances 50 which have a substantially circular perimeter portion 51. Therefore, in particular, the side wall 2 is formed by four sides having a substantially equal length to the diameter of the perimeter portion 51 of the windows for household appliances 50.

[0080] According to an aspect of the invention, the side wall 2 comprises reinforcement elements 10 arranged at the corners of the perimeter.

[0081] Preferably, the reinforcement elements comprise transverse partitions to the angular portions of the container 1 such as to guarantee greater structural rigidity in the points in which the weight of the pile of windows for household appliances 50 weighs more heavily, especially in the case in which various container 1 are stacked onto one another along the piling direction L.

[0082] According to another aspect of the invention illustrated in FIG. 2b, the side wall 2 comprises at least one projecting element 11 which extends along the piling direction L and, furthermore, is arranged at the main opening 3 so as to be coupled with a hollow 12 of a further container 1.

[0083] According to a further aspect of the invention, the side wall 2 has at least one hollow 12 at the bottom 4 so as to house a projecting element 11 of a further container 1.

[0084] According to an aspect of the invention illustrated in FIG. 2b, the side wall 2 has at least one pair of slots (not illustrated) for defining the gripping portions for an operator. According to a preferred aspect of the invention, the side wall 2 has a height comprised between 100 and 300 millimetres, a width comprised between 200 and 600 millimetres, a depth comprised between 200 and 600 millimetres.

[0085] In this way, the containers 1 can house windows for household appliances 50 of different shapes, but all substantially having the same structure, i.e. a substantially circular perimeter portion 51 which surrounds a convex portion 52 which extends transversally to the aforesaid circular portion 51.

[0086] In any case, the container 1 previously described can also be used for the storage of objects other than the windows for household appliances 50 but which have the same rough characteristics, i.e. a support portion (i.e. the perimeter portion 51) and a portion projecting with respect to the support portion (i.e. the convex portion 52).

[0087] Preferably, the container 1 is made of cardboard.

[0088] Even more preferably, the container 1 is made of cardboard sheets with a thickness comprised between 3 millimetres and 10 millimetres.

[0089] The present invention also concerns a system of containers 1 stackable onto one another, preferably along a piling direction L. In particular, the containers 1 have at least some of the characteristics previously described, individually or in different combinations with one another (unless alternative to one another).

[0090] FIG. 1 shows a pair of known containers configured for the storage of windows for household appliances 50, which are stacked onto one another according to the state of the art.

[0091] More precisely, FIG. 1 shows two boxes arranged vertically, i.e. with the opening arranged at the top, each of which contains a plurality of windows for household appliances 50 piled onto one another. Therefore, the windows for household appliances discharge their weight on the single point of contact defined by their own perimeter portion 51. To perform such stacking of boxes, the operators previously piled the windows for household appliances 50 onto one another which they subsequently placed inside the respective box with a single movement, i.e. all the windows for household appliances 50 together for a total weight of about 30 kilograms, were inserted side by side into the box to be arranged on the pallet.

[0092] Differently, FIG. 7 shows a pair of containers 1 for the storage of windows for household appliances 50 according to the present invention.

[0093] Advantageously, the windows for household appliances 50 were piled one by one into a container 1 until reaching a predetermined number or a total predetermined height. Subsequently, after preparing a plurality of containers 1a, 1b, the containers were stacked onto one another along the piling direction L. Advantageously, thanks to the secondary opening 6 present on the bottom 7 of each container 1, the pile of windows for household appliances 50 of the lower container 1a moved the movable flap 7 of the container 1 arranged above from the first closing position to the second opening position, remaining interposed between the two piles of windows for household appliances 50 for defining a layer able to dampen vibrations and impacts.

[0094] Preferably, the containers 1 of the system of containers according to the present invention, comprise both projecting elements 11 and hollows 12. In this way, each projecting element 11 of a first container 1a is configured to be inserted into a corresponding hollow 12 of a second container 1b arranged above the first container 1a so as to define a stack aligned along the piling direction L.

[0095] Advantageously, the containers 1 are piled onto one another easily as the projecting elements 11 and the hollows 12 provide alignment and centring elements.

[0096] According to an aspect of the invention, the system of containers 1 previously described can have some alternative embodiments to one another, one of which is illustrated in FIG. 8.

[0097] In particular, the system of containers 1 can be made like a single body having a vertical extension (tower configuration) as the largest dimension and internally subdivided into vertically overlapping modules each of which defines a container 1.

[0098] In other words, the piling direction L is vertical both for the windows for household appliances 50 and for the containers 1 among one another.

[0099] In accordance with such vertical tower configuration, for each pile of containers 1 the side walls 2 of the various containers 1 are defined by a part of side wall of the single body and, further, each bottom 4 of an intermediate container 1 (i.e. the one comprised between two containers in the pile) defines a partial cover for the container 1 below.

[0100] Alternatively, the system of containers 1 is made like a single body having a horizontal extension (chessboard configuration) as the largest dimension and internally subdivided into horizontally flanked modules each of which defines a container 1. In other words, the stacking direction between the containers 1 is orthogonal with respect to the piling direction L for the windows for household appliances 50 which is vertical. According to such horizontal chessboard configuration, each container 1 defines a module of a container with a larger dimension, wherein the bottom 4 is defined by a portion of the base of the single body, whereas the side wall 2 of each container 1 is defined by a portion of the side wall of the single body. The non-visible portions of the side walls 2 of the containers 1, i.e. the portions facing internally to the larger container, define a separation wall between each plurality of windows for household appliances 50 contained in each flanked container 1.

[0101] According to a further variant embodiment of the invention, the system of containers 1 comprises a single side wall 2 able to contain a grid of internal partitions able to simulate the chessboard configuration previously described. In other words, each section of the grid surrounded by a plurality of partitions, preferably 4, defines the equivalent of a container 1 for the storage of a plurality of windows for household appliances 50 piled onto one another along the vertical piling direction L.

[0102] The present invention further relates to a method for piling a plurality of windows for household appliances 50 having a projecting portion surrounded by a perimeter flange, in particular portholes, along a piling direction L.

[0103] In particular, the method comprises the following operating steps: [0104] providing a first container 1 having at least one of the characteristics previously described; [0105] piling a first plurality of windows for household appliances 50 in the first container 1a along the piling direction L so that the first pile of windows for household appliances 50 has a vertical dimension that is substantially greater than a value of the height of the first container 1; [0106] stacking a second container 1b above the first container 1a along the piling direction L so that the flap 7 of the second container 1b is moved from the first closing position to the second opening position enveloping at least in part the last window for household appliances 50 of the aforesaid first pile; [0107] piling at least a further window for household appliances 50 into the second container 1b along the piling direction L so as to compress the flap 7 of the second container 1b between itself and the first pile of windows for household appliances 50.

[0108] Preferably, the method also envisages a step of interposing a shock absorbing element, e.g. a layer of paper, between two windows for household appliances 50 of the same pile.
