Inclined baffles (20, 21) ensure locking of the handle (17), bridging between the top edges of two side walls (11, 13) of the container (10) and inclined edges of corresponding V-shaped notches provided at each end of the gripping handle (17).
Description
- The present invention relates to a stackable container, made of cardboard or similar material, provided with a suitable set back handle which facilitates transportation thereof.
- Cardboard boxes and containers are widely used for packaging or wrapping various articles, for transportation and despatch thereof.
- Generally use is made of corrugated cardboard containers for the packaging and transportation of various material, said containers sometimes being provided with a gripping handle which facilitates transportation. These cardboard containers are generally obtained from a flat blank comprising a plurality of panels side by side arranged which are folded along creasing lines so as to form the finished container, with or without a gripping handle.
- Within certain applications, for example for the packaging of paint containers or similar materials, there exists the problem of having particularly strong cardboard containers which are able to withstand heavy weights, for example of the order of a few tens of kilos, and can be stacked so as to reduce the space occupied both during transportation and warehouse storage and which at the same time can be easily gripped for lifting and transportation purposes.
- At present it is not known of any cardboard container having the aforementioned requirements and which is both inexpensive to manufacture and easy to erect or assemble.
- The object of the present invention is to provide a stackable cardboard container which is able to satisfy the aforementioned requirements and which moreover is provided with a particularly strong body and gripping handle for withstanding heavy loads, positioned in such a way that two or more containers can be stacked and placed on top of one another.
- The above can be achieved by means of a stackable cardboard container with an inset handle, having the features of the main claim.
- A preferred embodiment of a stackable cardboard container according to the present invention will be more described hereinbelow with reference to the accompanying drawings, in which:
- Fig.1
- is a perspective view of a container according to the present invention;
- Fig. 2
- is an enlarged cross-sectional view of the container according to Figure 1, along the plane of the gripping handle;
- Fig. 3
- is a cross-sectional view along the line 3-3 of Figure 2;
- Fig. 4
- shows the flat starting blank for forming the container according to Figure 1.
- As shown in Figure 1, the container according to the present invention substantially comprises a
body 10 of square or rectangular shape bounded byperipheral walls bottom wall 15 and by atop closing wall 16 which, as clearly shown, is set back with respect to the top edges of the side walls so as to define acavity 19, which is open upwards, for accommodating ahandle 17 provided with acentral gripping opening 18. - As clearly shown in Figure 1 and in the enlarged cross-sectional views of Figures 2 and 3, the
handle 17 has a height equal to or slightly less than the depth of thecavity 19 so that the top edge of the handle is arranged substantially flush with or in a position substantially set back from the top edges of the side walls. - A similar arrangement of the
gripping handle 17, in addition to being easy to take hold of and ensuring a particularly strong structure of the container, capable namely of transporting heavy loads of the order of a few tens of kilos, also enables two or more containers to be placed one on top of the other and stacked. - It is obvious, in fact, from the cross-sections of Figures 2 and 3 that the
bottom wall 15 of anoverlying container 10 rests fully on the edges of theside walls underlying container 10, thegripping handle 17 of which, being accommodated in the space which is formed between theopen top cavity 19 of theunderlying container 10 andbottom wall 15 of theoverlying container 10, does not interfere with the latter, thus ensuring a solid support and allowing stacking. - The
cardboard container 10 according to the present invention is moreover provided withslanted baffles 20 for strengthening and locking thehandle 17, whichbaffles 20 are connected to the top edges of twoside walls transverse slot 22 which is arranged against the inclined edges of corresponding V-shaped notches 23 formed at the two ends of thehandle 17. - The features of the
container 10 according to the present invention are more illustrated hereinbelow with reference to the blank of Figure 4 and the cross-sectional views of Figures 2 and 3. - The
container 10 is obtained from a flat corrugated-cardboard blank consisting of a plurality of panels and flaps which can be folded along cutting and creasing lines, as shown. - More precisely, the flat blank of Figure 4 comprises a set of four
central panels container 10, and agluing flap 21 along the end edge of thepanel 14. In Figure 4, the various broken lines which separate one panel from another indicate the crease lines for folding the various panels of the blank forming the container. - The blank in Figure 4 comprises moreover a second set of panels 15A, 15B, 15C and 15D, arranged on one side of the central set of panels, which during assembly of the container, are overlapping so as to form the
bottom wall 15 of the container. - The blank comprises finally a third set of side panels arranged on the opposite side to the one above, suitable for defining the
top closing wall 16, thegripping handle 17 and theslanted baffles 20 for strengthening the said container. More precisely, as shown in the top part of Figure 4, this third set of panels comprises two panels 16B and 16C which define thetop wall 16 of the container, which are connected to thepanels respective side walls - The third set of panels comprises, moreover, at the left-hand end of Figure 4 and in a middle position with respect to the panels 16B, 16C defining the top closing wall, two further
additional panels 20 designed to form the corresponding slanted baffles of the container, once assembled; thepanels 20 are provided withflaps 20A and 20B spaced apart by anintermediate slot 22 which partially extends into thesaid panels 20 such that, in the assembled condition of the container, thebaffles 20 and theflaps 20A, 20B can be arranged so as to straddle thegripping handle 17, as explained further below, with theflaps 20A and 20B folded against the panels 16B and 16D of thetop closing wall 16 of the container. - From Figure 4 it can be noted, moreover, that the additional panels 16A and 16C are spaced from the
central panels double creasing lines 24 which will form the thickened top edges of at least twowalls - Finally, Figure 4 shows that the blank has further additional panels formed in the region of the edge of the side panels 16B and 16C opposite to that connected to the central panels, for providing the
gripping handle 17. More precisely, the panel 16B is extended laterally by twoadditional panels 17A, 17B separated by a double creasing line 17C of suitable width for allowing the insertion of a third additional panel 17D, during shaping of thehandle 17, envisaged with the corresponding edge of the side panel 16D. Theadditional panels 17A, 17B and 17D for forming thehandle 17 have openings 18A, 18B and 18C which can be aligned with one another so as to form thehole 18 allowing to grasp thehandle 17 with one hand. The abovementioned panels forming thehandle 17 are therefore provided at their ends with V-shaped notches 23 for engagement with thelateral slots 22 of the panels forming theslanted baffles 20 which, in the assembled condition of the container, allow locking of thehandle 17 and the formation of abutment surfaces suitable for withstanding the weight of the product packaged inside the container. Since thehandle 17 has a thickness substantially triple that of the cardboard box, ample bearing surfaces are obtained, allowing the stresses and specific pressures to be reduced and hence even heavy weights to be lifted and transported. - Assembly of the box, starting with the blank shown in Figure 4, is performed substantially as follows: the blank is initially folded along the creasing lines which separate the series of central panels, gluing the
flap 21 to the inside of the wall defined by thepanel 11. The side panels 15A, 15B, 15C and 15D are then folded inwards, fixing them with a suitable adhesive so as to form thebottom wall 15 of the container. Then the two side panels 16B, 16D and 16A, 16C, respectively, are folded inwards, so as to arrange the latter adjacent to the twoside walls panels 17A and 17B are folded in a U-shape over it in accordance with the handle arrangement shown in the cross-sectional view of Figure 3; theother side panels 20 in the meantime remain folded outwards, as shown by the broken lines in Figure 1. - At this point the
side panels 20 can be folded inside of the container, towards and against thetop closing wall 16 which has thus been formed in a position set back with respect to the top edges of the said container. In doing so, thepanels 20 are arranged in the inclined position shown in Figure 2, with theflaps 20A, 20B folded against the top wall of the container, while thepanels 20 are arranged so as to straddle thehandle 17, in the condition shown in Figures 1 and 2, for engagement with and locking the handle since theslots 22 of thepanels 20 are inserted into the seats formed by the V-shaped notches 23 against the inclined edges of the notches themselves. In particular, as shown in the cross-sectional view of Figure 2, the twoslanted baffles 20 are arranged so as to form a bridge between the top edge of theside walls notches 23. By providing the edges of the V-shaped notches 23 with an inclination for example of between about 25° and 50°, thebaffles 20 are arranged with a complementary inclination which not only ensures a strong connection between thehandle 17 and thebaffles 20, but also, owing to the suitable inclination of the baffles and the ample surfaces making contact with thehandle 17, allow the coupling system thus formed to withstand considerable forces and hence tolerate even heavy weights inside a cardboard container of the kind described. - The inset arrangement of the
handle 17, inside acavity 19 which is open upwards and formed in the top part of the container, and the ample supporting surfaces offered by the edges of side walls therefore enable two or more containers to be stacked, without the handle interfering with the overlying container. - It is thus possible to provide a cardboard container which is extremely simple, particularly strong and suitable for achieving the aims of the present invention.
