Description

Field of the invention

The subject matter of the invention is a collective container used together with individual containers, especially for fruit, vegetables and mushroom, a collective container blank and a collective container kit with individual containers. The collective container can be used during transport, storage, sales, harvest and purchase of fruit, vegetables and mushroom.

Prior art

Collective packages used to collect, purchase, sell, transport and store fruit, mushroom and other products requiring transport in containers are often referred to as boxes, crates or, alternatively, containers. Such boxes, crates, containers or collective containers are usually made of corrugated cardboard, solid cardboard, polypropylene, planks or wood veneer.
Various types of fruit transportation boxes are known in the art.
Patent application PL211677 discloses an open-top container that can be stacked one on another and that is in the shape of a cuboid with an open-top surface, made of a single piece of flat, rigid sheet material, containing a horizontal bottom, vertical longer side walls, vertical shorter front wall, vertical shorter back wall, vertical stiffening walls, in which the cut lines, incision lines and/or scoring lines determine planes representing the horizontal bottom surface and vertical side walls, front wall and back wall surfaces connected to it at an angle of 90° using the clips, corner posts and reinforcing walls. The container can be machine or manually folded.
A prior art also discloses a cardboard sheet cut on a blanking die, which is manually folded by bending the four side walls (as shown in fig. 1). The two shorter walls are flap walls overlapping four tabs protruding from the long walls. Lock tabs on the shorter sides, after bending, enter so-called latches at the bottom of the box, which, at the same time, lock the flap walls with the tabs. The side and flap walls are, at the same time, structural elements, stiffening the package. The degree of stiffening depends on the quality and grammage of the corrugated cardboard used. The process of folding such a box takes approx. 15 seconds.
A prior art also discloses a cardboard sheet cut on a blanking die, which is automatically folded (as shown in fig. 2). The sheet, after cutting, is automatically collected from a feeder to a box forming machine. The bottom and side walls are created by bending the elements of the cardboard die cut by the machine. The flap elements are covered by fast-curing adhesive, which, after bending the side flaps, cures immediately. This stiffens the structure and provides the final form and shape. The side and flap walls are, at the same time, structural elements stiffening the package. The degree of stiffening depends on the quality and grammage of the corrugated cardboard. The process of folding such a box is fully automated and takes about 3 seconds.
These solutions according to the art do not, however, solve the drawbacks related to:

lengthy time of the manual folding process (this applies to boxes according to the art as presented in fig. 1); folding the box according to the art is labour and time consuming and takes about 15 seconds (as shown in fig. 1);
using an abundance of raw materials to produce a suitable blank; forming proper flaps is possible when using a significant amount of raw materials (as shown in figs. 1 and 2);
cost of transport (in the case of the prior art presented in fig. 2); when ordering automatically folded boxes, automatic folding results in the box being more structurally stable, but due to the fact that automatic gluing machines are very expensive, thus there is not a lot of them, transport and logistics of empty boxes from distribution centres is very expensive and burdensome, as well as empty boxes take storage space;
the lengthy, and thus expensive, process of fruit and vegetables cooling in the boxes. Fruit and vegetables cooling time inside the box is relatively lengthy, and forced circulation of cool air inside the box is significantly hindered by a closed bottom or insufficient number of vent holes which do not correspond with the holes in the individual containers inserted into collective boxes. Maintenance of the required temperature of fruit and vegetables in collective boxes is not easy and requires dedicated trucks. Due to the abovementioned aspects, the process of cooling fruit and vegetables is not easy and is expensive.

The mentioned drawbacks of the prior art containers and packages obstruct their application, especially by soft fruit planters; however, until now, they did not have much of a choice. There is a need on the market for new collecting containers that correspond to individual containers, the application of which is user friendly.
For this reason, the aim of the invention is the development of a collective container dedicated for proper individual container, which will be thrown away after a single cycle, disposed of or recycled, and additionally, it will be easy to handle and transport by a planter and be consumer friendly. The aim of the invention is to streamline the time-consuming stage of container folding on the spot or, in the case of glued boxes, transport the container in its final form, as well as to reduce the expensive process of cooling fruit and vegetables in boxes and make the process more effective.

Description of embodiments

According to the first embodiment, the invention applies to the collective container presented in fig. 1 cut out from a sheet of corrugated cardboard and designed for manual folding. The aspect of the invention was also presented in the form of the container blank in the form of a sheet cut out of corrugated cardboard presented on fig. 5 and figs. 8 - 11 presenting subsequent stages of folding the container from flat blank to three-dimensional collective container. Even though that in this aspect the collective container is designed for manual folding, it does not exclude the option of automatic or semi-automatic folding.
Fig. 5 presents collective container in the form of sheet blank before it is folded along bending lines and manually or otherwise folded in to the collective container form. As shown in fig. 5, the container blank has a form of a flat, rigid sheet material, which has a bottom 1, whose area is open in at least 70%. Persons ordinary skill in the art will notice that 70% of open bottom area can be achieved by making one hole of area corresponding to 70% of the bottom area of by making a few holes, preferably two or four, which total area is at least 70% of the bottom area.
The blank shown in fig. 5 also has side walls 4, 5 located adjacently to the bottom 1, correspondingly on its opposite sides: first side wall 4 adjacently with the first edge 14 to the bottom 1 and the second side wall 5 adjacently with the second edge 15 to the bottom.
Persons ordinary skill in the art will notice that side wall can have rectangular shape, but can also have a narrowing in the top part so that the middle part of the top edge of side walls is positioned slightly lower than the peripheral part of the top edge of side walls, as presented on the figure.
The blank also have external front vertical wall 2, wherein external front vertical wall 2 is located between internal front vertical wall 8 and the bottom 1. External front vertical wall 2 adjoins with its top edge to internal top edge of front vertical wall 8 and with the second edge, i.e. bottom and parallel to the top edge, to the bottom 1, and the two remaining edges of the internal front vertical wall are free.
On the side opposite to the bottom 1, the blank has external vertical back wall 3, wherein external vertical back wall 3 is located between internal front vertical wall 11 and the bottom 1 and the with the top edge it adjoins internal front vertical wall 11 and with the edge parallel to the top edge, i.e. bottom edge, to the bottom. The remaining two edges of external back vertical wall remain free.
As shown in fig. 5, internal front vertical wall 8 is located adjacently with its top edge to internal front vertical wall 2 and it is located on the side opposite to the bottom 1 and the internal back vertical wall 11 is located adjacently with its top edge to the external back vertical wall 3 and it is positioned on the side opposite to the bottom 1.
At the same time, bottom edge of internal front vertical wall 8 has lock tabs 27, 28 and the bottom edge of internal back vertical wall 11 has lock tabs 29, 30. Lock tabs are used as clips to lock internal walls in setting holes, 9, 10, 12, 13 located two each at the bottom edge of external front vertical wall 2 and bottom edge of external back vertical wall 2. Because of the lock tabs and setting holes, it is possible to provide stable container in a few seconds.
Fig. 5 presents also that setting fins 16, 17 extend from the top edge of external front vertical wall 2 in its peripheral part, and at its bottom edge on peripheral side of the wall 2, setting holes 9, 10 are cut out that correspond to setting fins 16, 17. Setting fins are used to stack the containers. When stacking the containers one on the other, setting fins are positioned inside the setting holes of the collective container positioned over the container with fins. Persons ordinary skill in the art will notice that setting fins can be placed in any location on the edge on condition that these locations correspond to setting holes.
The holder 6 is cut out in the centre of the top edge of external front vertical wall 2. The holder is used to lift the container.
Similarly, setting fins 18, 19 extend from the top edge of external back vertical wall 3 in its peripheral part, and at its bottom edge on peripheral side of the wall3, setting holes 12, 13 are cut out that correspond to setting fins, and a holder 7 is cut out in the centre. Protruding and cut out elements in the external back vertical wall have the same functions as those described above in case of external front vertical wall.
Leaves 21, 22, 23, 24 are the extension of shorter edges of side walls 4, 5, i.e. edges perpendicular to edge 14 and 15, adjoining the bottom 1, adapted to insert them inside the space between external and internal front vertical wall and between external and internal back vertical wall.
External 2 and internal 8 vertical front wall and external 3 and internal 11 vertical back wall as well as leaves 21, 22, 23, 24 are at the same time structural elements stiffening the container after assembly. The degree of stiffening depends on the quality and grammage of corrugated cardboard and the direction of waves in the corrugated cardboard. Alternatively, container blank is made of a cardboard, carton or polypropylene. As an example, one may use three-layer corrugated cardboard with wave B of thickness ca. 3 mm.
Collective container according to the first embodiment can be delivered in a flat version, in the form of a blank, as shown in fig. 5 for DIY assembly. At the site it is delivered to, it can be manually folded, wherein the folding takes significantly less than in case of a container according to prior art as presented on draw. 1.

Containers according to embodiments 1 - 3 are compatible as collective containers for fruit containers disclosed in patent application P- 415748 .
According to the fourth embodiment of the invention presented in fig. 4, the container has the form of a cut out sheet of corrugated cardboard and designed for semi-automatic folding. This does not exclude the option of automatic or manual folding. The container blank, according to the fourth embodiment is the same as the container blank according to the second and the third embodiment, but additionally has two M shaped holes adapted to receive cross-beam 35.
As presented in fig. 4,container M shaped holes 33, 34 are cut out in the central part of internal front vertical wall 8 and the central part of internal front vertical wall 11, and additionally the container has a cross-beam of cross-section in the form of the letter "V", wherein the cross-beam is set so that the ends of the cross-beam are positioned inside the M shaped holes and the cross-beam extends along the central longitudinal axis of the container.
Cross-beam 35 as shown in fig. 15 is made of flat, rigid sheet material, preferably corrugated cardboard in the shape of a rectangle, which is bent in the centre along the longer side to a V shape.
In the other aspect of the invention, M shaped holes and a cross-beam can be applied in containers according to the first embodiment.
The term "fixing means" is known to a person ordinarily skilled in the art and applies to hot gluing, cold gluing or by means of two-sided adhesive tape, but it also means binding using staples or stitching.
The surface of the collective container bottom 50% open according to the invention provides access of air to individual containers inside the collective container. The bottom of the container according to the invention can be open at least 50%, 60%, 70%, 75%, 80%, 85%, 90% or 95%. The percentage the bottom of the collective container according to the invention is open depends on the material the container is made of and the individual containers are made of which are inserted inside it. In one embodiment of the collective container according to the invention, opening the bottom surface provides at least one hole. However, the hole or holes are located so that they prevent the falling out of individual containers inserted inside the collective container according to the invention. More preferably, proper opening of the bottom provides one centrally located hole made in the bottom of the container according to the invention, which is similar to a rectangle in shape, wherein the remaining fragments around it provide sufficient support for individual containers placed inside the collective container according to the invention. In the alternative embodiment, when the collective container bottom opening is provided by two strips positioned along the bottom edges of the side walls, these are sufficiently wide to provide support for individual containers located inside the collective container according to the invention.
In one embodiment, the collective container according to the invention is used to store individual containers, the length of which corresponds to the width of the collective container according to the invention (i.e. the width of the wall formed by folding the internal and external front vertical walls and internal and external back vertical walls). The length of the collective container according to the invention (i.e. the length of its side walls) will be the multiplicity of individual containers widths which will be inserted in it.
Alternatively, it is possible to place inside the collective container according to the invention shorter containers than the width of the collective container. This is possible because of the cross-beam installed along the central longitudinal axis of the collective container. In this embodiment, shorter individual containers will be supported on one side on the bottom fragments or bottom strips, and on the other side on the cross-beam, which will prevent their falling out through the open surface of the bottom of the container according to the invention.
Alternatively, it is possible to place inside the collective container, according to the invention, containers of a length equal to half of the width of the collective container. In this embodiment, shorter individual containers will be supported on one side on the bottom fragments or bottom strips, and on the other individual container, which will prevent their falling out through the open surface of the bottom of the container according to the invention.
According to the fifth embodiment, the invention provides a kit comprising the collective container according to the invention and removable individual containers 36 located inside it. According to the invention, individual containers are any containers that can be used to harvest, purchase, transport and store soft fruit, such as punnets. The height of individual containers 36 basically corresponds to or is less than the height of side walls 4, 5 and the front and back walls formed by folding external vertical front wall 2 and internal vertical front wall 8, as well as external vertical back wall 3 and internal vertical back wall 11, so that is it possible to stack collective containers, according to the invention, which house individual containers. The width of containers 36 is selected so that the length of the collective container according to the invention, i.e. the length of its side walls 4, 5 represents the multiplicity of the width of the containers 36. This allows for matching the number of individual containers so that after inserting them into the collective container according to the invention they cannot freely move along the collective container, and at the same time it is possible to easily remove and insert them.
In one embodiment, the length of individual containers 36 basically corresponds to the width of the collective container according to the invention, i.e. the width of the front wall and back wall formed by folding external vertical front wall 2 and internal vertical front wall 8, as well as external vertical back wall 3 and internal vertical back wall 11. This means that individual containers are supported by fragments of the bottom 1 in the collective container according to the invention surrounding the hole, as mentioned in the first embodiment or alternatively they are supported by bottom strips 1a, 1b as mentioned in the second and the third embodiment. This way individual containers 36 cannot freely move sideways in the collective container according to the invention, and at the same time they are protected against falling through the bottom 1 of the collective container according to the invention.
Alternatively, in embodiment of the invention, individual containers 36 have a length less than the width of the collective container according to the invention. In such a case, it is necessary to apply the collective container according to the invention from the fourth , i.e. with cross-beam 35. In this case, individual containers are supported on cross-beam 35 on one side and on bottom 1 fragments or bottom strips 1a, 1b on the other.
A special form of the kit according to the invention is presented in fig. 16, which shows the collective container according to the first embodiment, which is additionally fitted with M shaped holes 33, 34 in the central part of internal front vertical wall 8 and the central part of internal back vertical wall 11, as well as cross-beam 35, where in it includes individual containers 36 located in two rows, one next to the other, which are inserted so that their shorter edges are positioned in parallel to side walls 4, 5 of the collective container and cross-beam 35 and longer edges are located parallel to external vertical front wall 2 and external vertical back wall 3. Moreover, each of the individual containers is supported by bottom strip 1a or bottom strip 1b from one side and by cross-beam 35 on the other. Such support precludes their falling out from the collective container according to the invention. Individual containers 36 are placed closely one next to the other, which precludes their shifting, but at the same time allows for easy insertion and removal of a container from the collective container according to the invention.
According to the sixth embodiment, the invention applies to the collective container presented in fig. 17 cut out from a sheet of corrugated cardboard and designed for manual folding. Even though in this aspect the collective container is designed for manual folding, it does not exclude the option of automatic or semi-automatic folding. The container blank in fig. 17 has the form of a flat, rigid sheet material, which has a bottom 1, whose area is open in 52% open. Persons ordinarily skilled in the art will notice that 52% of open bottom area can be achieved by making one hole of an area corresponding to 52% of the bottom area or by making a few holes, preferably two or four, whose total area is at least 52% of the bottom area. The container in fig. 17 is the same as the container in fig. 1, except that the bottom has a hole sized 52% of the bottom area.
According to the seventh embodiment, the invention applies to the collective container presented in fig. 18 cut out from a sheet of corrugated cardboard and designed for manual folding. In the seventh embodiment, the pre-cut has all the features of the pre-cut shown in the first embodiment of the invention, but it differs from the pre-cut shown in the first embodiment of the invention by the fact that it is made from corrugated board, wherein the orientation of the corrugation in the corrugated board, from which the pre-cut is made, is such that the direction of length of the internal corrugation in the board is parallel to the straight line running through the shorter side of the container base. Due to the orientation of the corrugation in the corrugated board, the structural strength of the container after folding from this pre-cut is significantly higher than in the case when the corrugation in the board would run parallel to the length of the base. For the sake of such orientation of the corrugation, the board is not crushed while the containers are stacked one upon another.
The containers according to the invention:

save up to 20% of raw materials, by using a new blank and removing the bottom - which is of great importance, not only from the costs standpoint, but environmental protection as well;
the box is delivered directly to the planter as a flat piece, which significantly reduces the costs of transport and storage;
the process of gluing takes ca. 5 seconds and is done by a simple semi-automatic machine, operated by an unskilled person;
due to the delivery of flat boxes, the storage space is reduced to a minimum;
significant improvement of cooling conditions of fruit inside the box from its bottom due to lack of the bottom and adapting individual containers to it, which significantly improves the circulation of cool air.

A new blank can be folded/glued manually directly in the plantation at a rate close to an automatic machine without engaging transport means and using the workforce. By eliminating the box bottom, faster fruit cooling is possible, which is very important in the cooling process as well as the transportation and logistics processes, and favourably affects the value and quality of fruit.
An advantage of the solutions according to the invention is the reduction of folding/gluing time from ca. 15 s in the prior art to ca. 5 s.
The application of semi-automatic folding for individual purposes eliminates distribution centres which are intermediaries between raw materials producers and planters. Because of the new blank, folding the new box is much easier and faster. This allows for the application of new boxes both by small producers of fruit and vegetables and by large planters.
