The present invention relates to a stackable and nestable box, depending on the needs, for the temporary storage of objects of various kinds such as, for example, screws, bolts, work tools, garments or stationery.
The invention is therefore part of the sector of space-saving containers capable of being both stacked (when filled) and nested (when empty).
Generally, a space-saving container has an upper open box configuration comprising teeth and housings able to match to respective housings and teeth of an identical lower space-saving container, thus realising a stack of containers. Space-saving containers of this type comprise a bottom wall and a side wall comprising side panels, a front panel and a rear panel, substantially defining a side wall raised from the bottom wall.
Such known containers are stackable or nestable by selecting the reciprocal position between two adjacent containers, in particular starting from two different positions differently staggered from each other.
Disadvantageously, an operator, to realise a stack of space-saving containers, must pay attention to the correct positioning of the container to be stacked with respect to a lower container, in such a way as to match the teeth with the respective housings and vice versa. Incorrect positioning could lead to unwanted collapse or accidental dropping of the container above.
Even more disadvantageously, when it is necessary to withdraw an object from an intermediate container of a stack of stacked containers, great care must be taken not to inadvertently impact the containers themselves during extraction, which would consequently cause a collapse of the stack.
In order to make the stacking of space-saving containers easier, it is known, as shown in document U.S. Pat. No. 5,071,008, to provide in each of the side panels at least one step facing the inside of the container itself and which is useful to act as a rest surface for an identical upper container, when stacked. Such a step further comprises a tooth capable of realising a side locking of an identical upper container, when stacked.
Disadvantageously, the space-saving container described in document U.S. Pat. No. 5,071,008 does not allow quick and easy stacking but requires exerting particular care by the user in order to arrange exactly the upper container on the lower one.
Furthermore, document U.S. Pat. No. 5,071,008 only provides for a side locking of the stacked containers, i.e. a limitation of the sliding of a stacked container along the front and rear panels.
In this context, the technical task underlying the present invention is to propose a space-saving container that overcomes at least some of the drawbacks of the prior art mentioned above.
In particular, the object of the present invention is to propose a stackable and/or nestable box with characteristics such as to facilitate an operator during the realisation of a stack of boxes.
A further object of the present invention is to propose a stackable and/or nestable box capable of preventing the collapse of a stack made with several boxes during a withdrawal of an object therefrom.
Furthermore, an object of the present invention is to propose a stackable and/or nestable box configured such that access to each box is readily and easily available, when stacked with one or more similar boxes.
Finally, an object of the present invention is to propose a stackable and/or nestable box capable of being stacked with other space-saving containers of the same size. Furthermore, the stackable and/or nestable box is able to be stacked also with boxes with compatible dimensions, i.e. substantially close to the dimensions of the stackable and/or nestable box, and normally not stackable with each other due to different design criteria chosen to carry out the stacking.
The technical task set and the objects specified are substantially attained by a stackable and/or nestable box comprising the technical features as set out in one or more of the appended claims.
Further features and advantages of the present invention will become more apparent from the indicative, and therefore non-limiting, description of preferred but non-exclusive embodiments of a stackable and/or nestable box.
Such a description will be set out below with reference to the accompanying drawings, which are provided solely for illustrative and therefore non-limiting purposes, in which:
With reference to
Preferably, the box 100 is defined by a single monolithic body, for example made of plastic material, in particular obtained by a moulding process.
With reference to
The box 100 is also configured to be stacked also with boxes with compatible dimensions, i.e. substantially close to the dimensions of the stackable and/or nestable box, and normally not stackable with each other due to different design criteria chosen to carry out the stacking.
With reference to
Considering a plurality of boxes 100, it is therefore possible to realise a stack 200 by arranging the boxes 100 in a first stacking configuration, in which the boxes 100 are superimposed, in a second nesting configuration, in which the boxes 100 are fitted (or nested) in each other, or in both of the above configurations.
With reference to
More in detail, the side panels 2a and 2b each have at least a portion that is recessing 3 from the containment volume “V” and at least one portion protruding 4 towards the containment volume “V”. In other words, both the panel 2a and the panel 2b have at least one recessing portion 3 and at least one protruding portion 4.
The recessing portion 3 is configured to easily fit into a corresponding recessing portion 3 of a lower box 100, when in a second nesting configuration.
As regards the first stacking configuration, the protruding portion 4 comprises at least one side rest surface 5, useful for defining a vertical support of an upper box 100. In other words, both the side panel 2a and the side panel 2b comprise at least one protruding portion 4, in turn comprising at least one side rest surface 5.
In particular, each recessing portion 3 of the box 100 is configured to rest on a corresponding side rest surface 5 of a lower box 100, when in a first stacking configuration.
As illustrated in
The side rest surface 5 further comprises a guide tooth 6 defining a guide surface 6a, as illustrated in
In detail, the guide surface 6a is inclined towards the base surface 5a and faces the containment volume “V”.
Preferably the guide tooth 6 is adjacent to the respective side panel 2a or 2b and progressively moves away therefrom towards the base surface 5a, i.e. towards the bottom wall 1. In other words, the inclination of the guide surface 6a is greater than the inclination of the respective side panel 2a or 2b.
In greater detail, the guide surfaces 6a are opposite and converging towards the base surface 5a, thus defining a side self-centring of a box 100 when it is stacked on a lower box 100.
In other words, both the side panel 2a and the side panel 2b comprise at least one side rest surface 5 comprising in turn a guide tooth 6, consequently, the guide surfaces 6a defined by the latter are opposite and converging with each other in the side panels 2a and 2b. Such convergence, during the realisation of the first stacking configuration, defines a side self-centring of a box 100, when it is stacked on a lower box 100.
In other words, considering the first stacking configuration, the guide surfaces 6a of a lower box 100 define a temporary rest for an upper box 100, such rest being made definitive and stable when an upper box 100 comes to rest on the respective base surface 5a of a lower box 100.
The guide surface 6a of the box 100 is then configured to define a gradual sliding of the recessing portion 3 of an upper box 100 towards the base surface 5a, the latter being intended to restingly receive the recessing portion 3 of an upper box 100, defining therewith a sliding coupling along the side panels 2a, 2b.
The conformations of guide surface 6a and base surface 5a allow the box 100 to be stacked with other boxes with compatible dimensions, i.e. with other boxes of similar dimensions and which are normally not stackable with each other due to the different design criteria for realising the stacking means.
More in detail, the guide tooth 6 has a length, measured along the side panel 2a or 2b from the bottom wall 1 to the front panel 2c, lower than the length, measured in the same way, of the corresponding protruding portion 4.
Preferably the length of the guide tooth 6 is less than half the length of the corresponding protruding portion 4.
With reference to
In particular, the lower side edge 7 is defined by an extension of the side panels 2a and 2b downwards from the bottom wall 1 in such a way as to follow the profile defined by the recessing 3 and protruding 4 portions. In other words, the recessing portions 3 and the protruding portions 4 extend downward from the bottom wall 1 defining the lower side edge 7.
During the realisation of the first stacking configuration, therefore, the lower side edge 7 of the box 100 gradually slides on the guide surface 6a of a lower box 100, thus realising a side self-centring, and then rests stably on the base surface 5a thereof.
In other words, the side rest surfaces 5 of the box 100, by means of the guide tooth 6 and the respective guide surface 6a, define a side self-centring of an upper box 100 during its stacking by guiding the lower side edge 7 thereof towards the base surface 5a.
The guide surface 6a of the box 100 is then configured to define a gradual sliding of the lower side edge 7 of an upper box 100 towards the base surface 5a, the latter being intended to restingly receive the lower side edge 7 of an upper box 100, defining therewith a sliding coupling along the side panels 2a, 2b.
Advantageously, therefore, the guide tooth 6 and the respective guide surface 6a are adapted to facilitate the realisation of the first stacking configuration.
When in the first stacking configuration, the lower side edge 7 of the box 100 rests on the base surface 5a of a lower box 100 defining therewith a sliding coupling along the side panels 2a and 2b.
In other words, when in the first stacking configuration, the side rest surfaces 5 of the box 100 realise, by means of the base surface 5a, a vertical support of an upper box 100 and a sliding coupling, with the lower side edge 7 of an upper box 100, along the side panels 2a or 2b.
With reference to
The retaining tooth 8 of the box 100 is configured to realise a side locking of an upper box 100, when in the first stacking configuration.
In other words, the retaining tooth 8 of the box 100 is configured to limit a sliding, along the front 2c and rear 2d panels, of an upper box 100 and in the first stacking configuration.
In greater detail, the retaining tooth 8 of the box 100 defines, together with the base surface 5a and the guide tooth 6, a housing adapted to receive the lower side edge 7 of an upper box 100, when in the first stacking configuration. Consequently, the retaining tooth 8 defines, together with the base surface 5a and the guide tooth 6, a prismatic or undercut coupling with the lower side edge 7 of an upper box 100, when in the first stacking configuration.
In other words, considering a lower box 100 and an upper box 100 in first stacking configuration, the former not only supports the latter vertically by means of its base surface 5a, which restingly receives the lower side edge 7 of the latter, but also locks the latter laterally by means of its retaining tooth 8, which constrains the lower side edge 7 of the latter to remain rested on the base surface 5a of the former.
Advantageously, moreover, considering once again a lower box 100 and an upper box 100 in first stacking configuration, the retaining tooth 8 of the first prevents the side wall 2 thereof from excessively deforming due to the weight of the second.
With reference to
In greater detail, the recess 7a of the box 100 is configured to be arranged astride, therefore to embrace, a respective base surface 5a of a lower box 100, when in a first stacking configuration. Consequently, the base surface of a lower box 100 is housed within the recess 7a of an identical upper box, when in first stacking configuration. In other words, the recess 7a limits a relative sliding along the side panels 2a and 2b between two boxes 100 when stacked on top of each other.
Advantageously therefore, the recess 7a ensures a greater stability of a stack 200.
Even more preferably, the recess 7a defines a side cavity 7b, turned internally, shown in
The side cavity 7b of the box 100 is configured to receive the retaining tooth 8 of an upper box 100, when in the first stacking configuration.
Advantageously, the insertion of the retaining tooth 8 of a lower box 100 into a respective side cavity 7b of an upper box 100 ensures greater stability of a stack 200. In fact, the cavity 7b further limits a relative sliding along the side panels 2a and 2b between two boxes 100 when stacked on top of each other.
With regard to the side panels 2a and 2b, an embodiment of the box 100 is contemplated in which the side rest surface 5 comprises firstly a base surface 5a, intended to restingly receive a lower portion of an upper box 100 in a first stacking configuration, and secondly a guide tooth 6, configured to realise a side self-centring of an upper box 100 during the realisation of the first stacking configuration.
A further embodiment of the box 100 is also contemplated in which the side rest surface 5 comprises, in addition to the base surface 5a and the guide tooth 6, also the retaining tooth 8.
Preferably, the guide tooth 6 and the retaining tooth 8 have a height, measured by the bottom wall 1 rising along the respective side panel 2a or 2b, lower than the height of the side panels 2a, 2b measured in the same way.
Advantageously, this feature allows to place in the first stacking configuration, with a box 100 subject-matter of the present invention, any identical box and having the same dimensions, even if this is not configured to be stackable with other boxes identical thereto.
With reference to
The step 11 is turned towards the containment volume “V” and is configured to restingly receive a lower portion of an upper box 100 when in the first stacking configuration.
In other words, when an upper box 100 and a lower box 100 are in a first stacking configuration, the lower side edge 7 of the first rests on the base surface 5a of the second and a lower rear portion of the first rests on the step 11 of the second.
In this case, there is therefore provided a vertical support of an upper box 100 both laterally, by means of the base surface 5a of a lower box 100, and, behind, by means of the step 11 of a lower box 100.
With reference to
With reference to
Preferably, the rear panel 2d of the box 100 comprises above, at the receiving portion 9, a locking tooth 12 facing the containment volume “V” and defining the receiving portion 9.
Even more preferably, the rear panel 2d of the box 100 comprises two locking teeth 12.
In particular, the locking tooth 12 is far from the rear panel 2d and, as shown in
The receiving portion 9 is then defined behind by an end portion of the rear panel 2d and in front by one or more locking teeth 12.
In other words, the locking tooth 12 defines a housing adapted to receive the lower rear edge 10 of an upper box 100, and to retain it stably and in a predetermined position.
The locking tooth 12 then allows the lower rear edge 10 of an upper box 100 to be engaged, advantageously providing a useful support to facilitate the realisation of the stacking configuration.
Considering the box 100 in the first stacking configuration, there is consequently provided a front locking thereof operated by the locking tooth 12 of a lower box 100, i.e. a limitation to the sliding of the box 100 along the side panels 2a and 2b.
Preferably the receiving portion 9 further provides a vertical support of an upper box 100 in first stacking configuration.
In this case, as shown in
Even more preferably the step 11 comprises two locking teeth 12, arranged at the same distance from a central point of the step 11.
In particular, the locking tooth 12 is far from the rear panel 2d and defines with the step 11 the receiving portion 9 of the box 100, configured to provide a vertical support and retain stably and in a predetermined position a corresponding lower portion of an upper box 100 when in the first stacking configuration.
In other words, the locking tooth 12 defines, with the step 11, a housing adapted to receive the lower rear edge 10 of an upper box 100 providing a vertical support thereof and retaining it stably and in a predetermined position.
More in detail, the locking tooth 12 allows to hook the lower rear edge 10 of an upper box 100, advantageously providing a support useful to facilitate the realisation of the stacking configuration.
In this case, if an upper box 100 and a lower box 100 are in the first stacking configuration, the lower side edge 7 of the first rests on the base surface 5a of the second, furthermore, the lower rear edge 10 of the first rests on the step 11 of the second, fitting into the respective receiving portion 9.
Considering the first stacking configuration, there is therefore provided a vertical support of an upper box 100 both laterally, by means of the base surface 5a of a lower box 100, and behind, by means of the step 11 of a lower box 100.
Considering the first stacking configuration, there is further provided a front locking operated by the locking tooth 12 of a lower box 100, i.e. there is provided a limitation to the sliding of an upper box 100 along the side panels 2a and 2b.
In other words, considering the first stacking configuration, with front locking it is meant that the locking tooth 12 of a lower box 100 limits the sliding on its base surface 5a of a stacked upper box 100, from the rear panel 2d towards the front panel 2c.
Preferably, the locking tooth 12 defines a corresponding rib 13, illustrated in
Even more preferably, the rib 13 extends from the locking tooth 12 towards the bottom wall 1 preferably up to the bottom wall 1 itself and acts as a spacer between the rear panel 2d of the box 100 and the rear panel 2d of an upper box 100, when in a second nesting configuration.
In particular, the rib 13 is in relief from the rear panel 2d towards the containment volume “V”.
In other words, as shown in
As regards the rear panel 2d, an embodiment of the box 100 is contemplated comprising only a step 11, configured to provide a vertical support of an upper box 100 when in the first stacking configuration.
An embodiment of a box 100 is also contemplated in which the rear panel 2d comprises at least one locking tooth 12 configured to define a receiving portion 9 capable of retaining, stably and in a predetermined position, the lower rear edge 10 of an upper box 100, when in a first stacking configuration.
A further contemplated embodiment relates to a box 100 in which the step 11 comprises at least one locking tooth 12.
With reference to
Furthermore, the front panel 2c has a height, measured by rising from the bottom wall 1 along the front panel 2c, lower than a height of the rear panels 2a and 2b, measured by rising from the bottom wall 1 respectively along the rear panels 2a and 2b.
In other words, the front panel 2c is lower than the other panels 2a, 2b, 2d of the box 100.
Advantageously, this feature makes access to the box 100 readily and easily available, when stacked with one or more boxes 100. Considering a stack 200 of boxes 100 in first stacking configuration, in fact, the lower height of the front panel 2c allows defining, between the front panel 2c of a lower box 100 and the bottom wall 1 of an upper box 100, an access portion to the contents of the box 100.
In order to facilitate the manual transport of the box 100, a gripping portion and a gripping portion 17a are also provided.
With reference to
With reference to
In detail, the side crown 16 has an indentation 17, advantageously useful for realising the gripping portion 17a, preferably the side crown 16 is compatible with metal guides. In other words, the side crown 16 and more particularly the side portion at least partially defining the gripping portion 17a, is shaped so as to be slidable on metal guides.
The present invention reaches the proposed object, overcoming the complained disadvantages of the prior art.
Advantageously, the box 100 subject-matter of the present invention, thanks to the guide tooth 6 and to the respective guide surface 6a, as well as thanks to the rear receiving portion 9, is able to facilitate the realisation of a stack 200 of boxes 100.
Even more advantageously, the locking tooth 12 provides additional support for an operator during the realisation of a stack 200 of boxes 100.
Advantageously, the box 100, by means of its locking tooth 12 and its retaining tooth 8, is able to prevent the collapse of a stack 200 made with several boxes 100 during a withdrawal of an object therefrom. Faced with a possible impact by an operator, in fact, the locking tooth 12 provides stability along the side panels 2a and 2b while the retaining tooth 8 provides stability along the front 2c and rear 2d panels.
Advantageously, the lower height of the front panel 2c with respect to the side panels 2a, 2b and with respect to the rear panel 2d allows an operator to readily and easily access each box, when stacked with one or more boxes 100.
Advantageously, the lower height of the guide tooth 6 and the retaining tooth 8 makes the box 100 stackable with other space-saving containers normally not stackable between them.
