Description

DESCRIPTION

Stackable box

Object of the invention

The present invention application as a utility model is about a stackable box.

The present invention aims to optimize current boxes, commonly made of plastic, which are used to contain or display products, in particular fruits and vegetables.

The peculiarities and advantages of the invention in question will become more apparent after a brief description of the known state of the art and its types of drawbacks.

Background

Plastic molded boxes have been known for some time, and generally comprise a lower panel or bottom and four lateral sides, two of them longitudinal and two transverse, that define a compartment within which products, in particular horticultural products, are deposited.

For containment reasons, the lateral sides are inclined so that the box has a conical shape with increasing dimensions going from bottom to top so that a first box can be partially inserted into a second box identical to the first in order to to reduce overall dimensions during storage or transportation.

In particular, when the boxes are empty, these boxes must be inserted into each other in a rest position, in order to reduce the height of the stack of boxes. When the boxes are full, these boxes should be arranged one on top of the other, in an environment operating, leaving enough space between the lower box and the upper box, so as not to crush the products that are contained in the lower box.

The present invention relates in particular to those stackable boxes in which the transverse sides and / or the longitudinal sides include sets of projections and recesses obtained differently on the two opposite sides in such a way that when the two boxes are oriented in the In the same way, the boxes can be inserted one inside the other in a configuration with a minimum of impediment, while if the two boxes are rotated 180 ° from each other, they can be placed one on top of the other since the notches of the sets The shoulders and recesses of the upper case rest on the projections of the sets of shoulders and recesses of the lower case.

In particular, these boxes usually comprise two sets of projections and recesses on the longitudinal sides and two sets of projections and recesses on the transverse sides. Each set of shoulders and recesses comprises a shoulder and a recess positioned side by side and connected by sharp corners.

In the same way, each shoulder and recess is connected to its own side by sharp walls and corners.

At the top of the aforementioned shoulders are suitable supporting surfaces to support a top box.

These prior art boxes have a first drawback due to the presence of sharp corners that can ruin and damage the products stored inside the box, especially if the products are fruits and vegetables. In fact, during the transport of the boxes, the products move inside the box compartment, inevitably impacting against the sharp corners with consequent damage to the products.

A second drawback that affects these boxes is related to the fact that the sets of projections and recesses are obtained in a central part of the sides and therefore are strongly affected by the deformations of the sides themselves caused by the content of the interior. from the box.

It is precisely the observation of the problems described above that led to the conception of the new box according to the invention, thanks to which it is believed that the above problems can be overcome.

Brief description of the invention

In particular, the purpose of the present invention is to overcome the drawbacks of the known technique, by designing a box, in which the sets of projections and recesses are shaped in such a way that they do not damage and at the same time protect the products stored in inside the box.

Another purpose of the present invention is to design a stackable box that can be placed on top of another box in an operative position to form an extremely stable vertical row of boxes.

Another object of the present invention is to devise an inexpensive and extremely robust stackable box.

A further object of the present invention is to devise a stackable box in which the sets of shoulders and recesses are minimally affected by any deformation of the side on which they are molded.

These purposes are achieved in accordance with the invention with the features listed in the attached independent claim 1.

Advantageous embodiments appear from the dependent claims.

The box according to the invention is defined by claim 1.

Description of the invention and preferred embodiments

With reference to the attached figures, a box according to the invention is described, indicated as a whole with the reference number (1).

The stackable box (1) has a parallelepiped shape and comprises:

- a compartment (15);

- a lower panel or bottom (10) comprising a lower face (10b) and an upper face (10a);

- a first and a second transverse side (13, 14), opposite each other and comprising an upper edge (17c, 17d), an inner face, facing the compartment (15), and an outer face, facing outward the compartment (15);

- a first and a second longitudinal side (11, 12) opposite each other and comprising an upper edge (17a, 17b), an inner face, facing the compartment (15) and an outer face, facing the outside of the compartment (fifteen);

- an upper access opening to the compartment (15) delimited by the upper edges (17a, 17b, 17c, 17d) of the sides (11, 12, 13, 14);

- four corners (A1, A2, A3, A4) each connecting two adjacent sides (11, 12, 13, 14).

With particular reference to Figure 2, the longitudinal sides (11, 12) and the transverse sides (13, 14) each comprise two sets of shoulders and recesses (G1, G2) for a total of eight sets of shoulders and recesses ( G1, G2).

Each set of projections and recesses (G1, G2) comprises a support surface (S) suitable to support a stackable box arranged on the box (1) and a support surface (H) suitable to rest on a stackable box placed underneath. the box (1).

Each set of shoulders and recesses (G1, G2) comprises at least one shoulder and recess part (2, 3) on the side extending from the bottom (10) towards the upper edge (17a, 17b, 17c, 17d).

At least one shoulder and recess section (2, 3) comprises a rectilinear section (20, 30) parallel to the side (11, 12, 13, 14) and one or two lateral curved connecting sections (21, 31) connecting the straight section (20, 30) with the side (11, 12, 13, 14) or with another adjacent raised and recessed section of the assembly (2, 3).

In particular, again with reference to Figure 2, the sets of shoulders and recesses (G1, G2) can be divided into two types of sets of shoulders and recesses (G1, G2), one of which is a first type of sets of shoulders and recesses (G1) and the other is a second type of sets of shoulders and recesses (G2).

The raised and lowered set (G1) according to the first type is arranged on the longitudinal sides (11, 12), while the raised and lowered set (G2) according to the second type is arranged on the transverse sides (13, 14).

Each raised and lowered set (G1) of the first type comprises:

- a shoulder and recess section (2, 3) of the recess type (2) having a concavity oriented towards the center of the compartment (15) and comprising a rectilinear section (20) retracted with respect to the transverse side (11, 12) on which the raised and lowered assembly (G1) is arranged; Y

- A raised and recessed section (2, 3) of the raised type (3) comprising a rectilinear section (30) that advances with respect to the transverse side (11, 12) on which the raised and lowered assembly ( G1).

The second type of sets of shoulders and recesses (G2) exclusively comprises a section of shoulder and recess (2, 3) of the recess type (2) that has a concavity oriented towards the center of the compartment and that includes a rectilinear section (20) retracted with respect to the transverse side (13, 14) on which the raised and lowered assembly (G1) is arranged.

Each raised (3) or recessed section (2) comprises two lateral curvilinear connection sections (21; 31) that connect the rectilinear section (20, 30) to the side (11, 12, 13, 14) or to the other shoulder section and recess (2; 3) adjacent to the same raised and recessed assembly (G1).

The curved connecting part (21, 31) has at least one part, which extends over an arc of circumference of approximately 90 °, which has a radius of curvature greater than or equal to 12 mm, preferably 13 mm.

In particular, the curved connection part (21, 31) may comprise only a part (with a radius of curvature of 13 mm) that extends through an arc of circumference of approximately 90 °; or it may be substantially "S" shaped and comprise a first part and a second part having two opposite concavities (with radii of curvature greater than 12 mm, preferably 13 mm) and joined together by a short central rectilinear section.

In the first type of sets of bosses and recesses, or rather in the sets of bosses and recesses arranged on the longitudinal sides (11, 12), at the top of each raised section (3) a support surface ( S).

In the second type of sets of shoulders and recesses (G2), or rather in sets of shoulders and recesses (G2) arranged on the transverse sides (13, 14), the support surfaces (S) are located near the edge upper (17c, 17d) of the transverse side (13, 14) in correspondence with the curvilinear connecting side section (21) that connects with a section (TR) of the transverse side (13, 14).

With reference to Figure 3, the bearing surfaces (H) are molded into the lower face (10b) of the bottom (10) of the box (1) in correspondence with the recessed section (2).

Each support surface (H) is designed to rest on one of the support surfaces (S) of the lower box, when the box (1) rotates 180 ° with respect to a lower box (1) so that they can be stacked two boxes (put them in operational order).

The recessed sections (2) of each raised and recessed assembly (G1, G2) have a tapered shape with increasing dimensions running from the bottom (10) towards the top edge (17a, 17b, 17c, 17d). The raised sections (3) of each raised and recessed assembly have a tapered shape with decreasing dimensions running from the bottom (10) towards the top edge (17a, 17b, 17c, 17d).

With particular reference to Figure 6, the support surface (H) lies in a plane arranged at a higher level than the plane in which the lower face (10a) of the bottom (10) of the box (1 ).

More precisely, the plane on which the lower face (10a) of the bottom (10) is located and the plane on which the support surface rests are separated by a distance (v) of between 0.5 mm and 3 mm.

This arrangement allows the support surfaces (H) not to be worn or damaged, in the event that the box (1) is made to slide along the ground.

Preferably, referring to Figures 5A and 6, each raised and lowered assembly (G1, G2) comprises:

- a tooth (D) arranged on the support surfaces (S) and projecting towards the upper edge of the sides (11, 12, 13, 14); Y

- a seat (E) arranged at the bottom (10) and adapted to receive the tooth (D) of a second stackable box arranged below the box (1); the seat (E) is made close to the support surface (H).

With reference to Figure 7, each upper edge (17a, 17b, 17c, 17d) of the sides (11, 12, 13, 14) comprises:

- an upper horizontal wall (71) having a free edge facing the outside of the compartment (15);

- a lower horizontal wall (72) having a free edge facing the outside of the compartment (15);

- a vertical wall (73) connecting the upper horizontal wall (71) to the lower horizontal wall (72).

The upper horizontal wall (71), the lower horizontal wall (72) and the vertical wall (73) define a seat (7).

The box (1) comprises horizontal ribs (8) between the lower horizontal wall (72) and the upper horizontal wall (71) that protrude with respect to the free edge of the horizontal walls (71, 72).

The horizontal ribs (8) of the upper edge (17a, 17b, 17c, 17d) of one of the sides (11, 12, 13, 14) are offset with respect to the horizontal ribs (8) of the upper edge (17a, 17b , 17c, 17d) from the opposite side (11, 12, 13, 14). In this way, the ribs of the upper edge of one side are arranged between the ribs (8) of the upper edge of the opposite side of another box, interlacing the two boxes with each other, as shown in figure 7.

This structural peculiarity allows a stable coupling between adjacent vertical rows of boxes. In particular, this makes it possible to give high stability to the adjacent vertical rows of boxes arranged on a pallet.

Again with reference to figure 7, preferably on the upper edges (71a, 71b, 71c, 71d), at the corners (A1, A2, A3, A4) of the box (1) there are holes for the passage and the guide of the strapping.

In particular, the holes are arranged in the vertical wall of the upper edge and are delimited in the upper part by two inclined rods (M1, M2), in which:

- an upper inclined rod (M1) is connected on one side to the free edge of the upper wall (71) and on the other side to the vertical wall (73);

- a lower inclined rod (M2) is connected on one side to the free edge of the lower wall (72) and on the other side to the vertical wall (73).

The two inclined rods act as a means to induce and center for centering the belt between the two inclined rods.

Next, with reference to Figure 2A, the conformation of the first type of raised and lowered assembly (G1) and of the second type is described by way of example. raised and recessed assembly (G2) arranged near the corner (A3) interposed between the second longitudinal side (12) and the second transverse side (14).

The raised and lowered set (G1), located on the second longitudinal side (12) and adjacent to the corner (A3), has:

- the raised section (3) that includes the straight section (30), a first lateral section of curvilinear connection (31) substantially in the shape of an "S" that connects the straight section (30) to the second longitudinal side (12), and a second lateral curvilinear connection section (21) that connects the rectilinear section (30) with the lowered section (2) of the same raised and lowered assembly (G1); Y

- the recessed section (2) that includes the straight section (20), a first curvilinear connection side section (21) that connects with the second curvilinear connection side section (31) of the raised section (3) and a second connection curvilinear of the lateral section that connects the straight section (30) with the second longitudinal side (12), in correspondence with the corner (A3).

The raised and lowered set (G2), located on the second transverse side (14), has:

- the recessed section (2) that includes the straight section (20), a first curvilinear connecting side section (21) that connects the straight section (20) to the second transverse side (14) at the corner (A3) and a second lateral section of curvilinear connection (21) to "S" that connects the straight section (20) to the section (TR) of the transverse side (14), in correspondence with which the support surface (S) is obtained.

In light of the foregoing description, it is now clear what the idea of a solution was that would allow the problems of the known and disclosed prior art to be solved.

In fact, by providing the curvilinear side connecting sections (21, 31) with a curvature greater than 12 mm (preferably 13 mm), the risks of damage and bruising of the horticultural products stored inside the box are drastically reduced.

In addition, through experimental tests it has been verified that the presence of the curvilinear lateral sections allows the force of the weight of the upper box to be distributed more homogeneously throughout the box compared to what happens on the contrary using the existing boxes in the prior art.

Furthermore, having provided the different sets of projections and recesses close to the corners (A1, A2, A3, A4), such sets of projections and recesses (G1, G2) are not affected by any deformation of the sides (11, 12 , 13, 14) caused by the transported content.

Numerous detailed variations and modifications may be made to the present embodiment of the invention, which would be within the scope of one skilled in the art, however, would still fall within the scope and scope of the invention as expressed by the following claims.
