   Technical solutions relate to a combined container for transportation and storage of goods

The current state of technology

   For the transportation of various types of goods, different packaging, boxes or containers are used in which the goods are stored. Among the most well-known methods of transporting goods, “cast containers” are used. These “molded containers” are manufactured using molds and consist of a uniform material. The disadvantage is a high initial investment in casting equipment, more weight, with a growing drawer height, loss of internal cargo dimensions (necessary slopes after removal from the molds). Cast containers have a final useful life. If the cast material is damaged and can no longer be used, then the entire container is discarded and crushed as a means for plastic recycling. As an alternative, a molded container may be obsolete or undesirable if the parts for which it is offered are no longer in use. Other known methods for transporting goods include “construction containers”. They consist of the base of a cut flat material (using a cutting tool) and a mounting profile (made using a mold). They are mainly used to produce atypical sizes compared to molded containers for small order quantities. The disadvantages of “construction containers” are higher serial costs, often limited carrying capacity and more expensive recycling. From patent application No. EP2368683, a container is known which is created from a cut molded container or a structural container. This cut container forms the lower part (lower frame) and the upper part (upper frame) of the new container, with a central section inserted between these cut sections, which is referred to as a shell. This central section is welded to the lower and upper sections from a cut molded container. The disadvantage of these welded containers is the difficulty in positioning the lower and upper sections of the cut molded container with respect to the central section, when it is necessary to fix the position before welding. The position is fixed with the help of insets, which are made in the central section, and ribs, which are located on the cut sections of the molded containers, are inserted into these insets. Even fixing the position with the ribs will not provide trouble-free positioning of the central section for welding the upper and lower sections of the cut molded container, therefore the upper and lower sections must be mechanically fixed before welding, which is very disadvantageous. Another drawback of this container is that in case of damage it can no longer be used.

The essence of the technical solution :

 The disadvantages of the known methods of transportation and storage of goods eliminates the combined container in accordance with the technical solution. The combination container includes lower and upper sections, which are made of a used or new cut plastic molded or structural container. On the cut section of the container, i.e., between the lower and upper sections, a central section is put on (inserted), which consists of plastic with two open sides, and this central section can be of different heights. The principle of the technical solution is that the inserted central section with one open side is connected in the lower perimeter to the lower section, and the second open side in the upper perimeter is connected to the upper part with lock joints. The locking joint includes a first locking section formed on a vertical rib of the lower section and a vertical rib of the upper section. The vertical ribs on which the first lock section is created are the original ribs created on a cut molded or structural container. This first locking section is included in the second locking section, which is created on the side of the lower perimeter and on the side of the upper perimeter of the shell of the Central section.

 Depending on the design of the second lock section, the lock connection is closed or open. The surface of the closed lock connection on the central section around the second lock section is fixed - integral. The open lock connection is designed in such a way that a slot extends from the second lock section towards the open side of the central section. This slot allows you to simplify the connection and insertion of the second locking sections in the first locking sections formed on the vertical ribs of the lower and upper sections, since the wall of the central section with the slot is more pliable. A lock connection consisting of one first lock section and one second lock section is called a single lock connection. In many cases, it is necessary to make a combined container, which will be larger in size and will carry more weight of the goods transported, so it is necessary to double the lock joints. To create a double locking connection, two first locking sections are created on the vertical edges of the lower and upper sections, and two second locking sections are created on the central section. This type of lock connection is referred to as double closed or double open. The surface around the second lock section of the double closed lock connection in the central section is fixed - integral. The double open lock connection is designed so that a slot is made of two lock sections towards the open side of the central section and two lock sections located one above the other are also connected by the slot. And if you can even create triple or multiple lock joints, such a design in practice is not suitable. In some cases, the use of a combined container will be required, especially when storing goods, so that at least one side of the connected sections is open, i.e. formed an open surface. Through it, goods will be placed or delivered from the container. This may be a shorter front or side longer side or a combination of sides. Although the locking joints will provide sufficient strength with the locking joint for the connected sections of the combined container, the strength of the connected sections can be further enhanced by mutual welding at several points or by mechanical connection.

 These locking joints exclude the possible separation of the components of the container during operation and the subsequent loss or damage of the goods contained in the container. Thus, the presence of lock joints is necessary for the reliable implementation by the device of its purpose - capacity for transportation and storage of goods.

 The advantage of the technical solution is the low cost of mass production, the almost zero cost of expanding the product range, the use of already worn, partially broken or otherwise unused cast or structural containers, low weight, depending on the type of material used, the necessary load resistance can be obtained. The material of the individual sections of the combined container in most cases will be plastic. A combination with other materials is not ruled out. The combined container can be used for transporting industrial goods, for example, in the automotive, engineering, electrical industries, etc., as well as for transporting food, medicine, toys and similar goods.

Execution example

The combined container 10 for transporting and storing goods, shown in Figures 1 to 18, is made of a conventional or used molded or structural container. This ordinary molded or structural container will be cut approximately in the middle, and this will create the lower section 1 (in the following text the name “lower frame 1 ” will be used) and the upper section 2 (in the further text the name “upper frame 2 ” will be used). A central section 3 will be inserted between the lower frame 1 and the upper frame 2 , which consists of a shell with two open sides, and this central section 3 can be of different heights depending on the type of goods transported or stored. In shape, this central part 3 corresponds to the shape of the lower frame 1 and the upper frame 2 . This central section 3 is connected with the open sides to the lower frame 1 and to the upper frame 2 by means of locking joints 4 . The locking joints 4 are created on the surfaces of the lower perimeter 3.1 and on the surfaces of the upper perimeter 3.2 of the central section 3 and on the vertical ribs 1.1 of the lower frame 1 , and on the vertical ribs 2.1 of the upper frame 2 . Depending on different versions, as well as depending on the number of locking joints 4 created between the connected central section 3 with the central frame 1 and the upper frame 2 , the connected sections can be used without subsequent further fixation or can be fixed against separation by welding or mechanical detachable or one-piece connection. In all the examples of execution described below, a combined container 10 is assumed, including a structurally modified lower frame 1 and an upper frame 2 made of a molded or structural container, to which a central section 3 (central shell) is attached by a lock connection 4 .

In fig. 1 to 4, a combined rectangular container 10 with four locking joints 4 , which are created on opposite long sides of the connected sections, is shown. The arrangement of the locking joints 4 is decided so that at the lower frame 1 on each longer side on one initial vertical rib 1.1, a first locking section 4.1 is created , including a recess 4.11 and a protruding section 4.12 , which remains from the original vertical edge 1.1 of the cut container. The first locking parts 4.1 on the lower frame 1 are placed diagonally relative to each other (Fig. 2 and 3). For such an upper frame 2, on each longer side, on one initial vertical rib 2.1 , the first locking section 4.1 was created , including a recess 4.11 and a protruding part 4.12 , which remained from the original vertical rib 1.1 (Figs. 2 and 4). At the lower circumference of 3.1 and 3.1 on the upper perimeter of the central section 3 with respect to the first sections 4.1 keyhole lock Creates a second section 4.2, which form a hole extending through the wall of the central section 3. This hole in shape is decided so that protruding sections 4.12 of the first lock section 4.1 enter into it. The second locking section 4.2 is surrounded by a fixed wall of the central section 3 , so this locking connection 4 is called closed. Since the lock connection 4 is formed by one first lock section 4.1 and one second lock section 4.2 , this lock connection 4 is called a single closed lock (NOTE: for example, Figs. 1 3 and 1 4 show a double closed lock connection, see further description to to these figures). In order to stabilize the parts to be connected, on the lower frame 1 and on the upper frame 2 of the cut container, structural changes were made and vertical ribs 9 were left, which were inserted into the grooves 11 created on the lower perimeter 3.1 and on the upper perimeter 3.1 , connected by the central section 3 . Two grooves 11 are created on the shorter sides of the joined sections and one groove 11 is created on the long sides. When connecting the central section 3 with the lower frame 1 and with the upper frame 2, the central section 3 is put on the lower frame 1 and the upper frame 2 , after the first lock section 4.1 enters the second lock section 4.2 and this will create a lock connection 4 . The connection of the central section 3 with the lower frame 1 and the upper frame 2 using four lock joints 4 will provide a sufficiently accurate position of the parts to be connected for possible subsequent fixation by means of a mechanical connection, for example, welding at points 12, or will be provided with a detachable or one-piece connection in points 13 on the shorter sides of the combination container 10 .

In fig. 5 and 6, a combined rectangular container 10 is shown, in which each side of the central section 3 is connected on the lower perimeter 3.1 and on the upper perimeter 3.1 with the lower frame 1 and the upper frame 2 with two lock joints 4 , the entire lower frame 1 with the side of the perimeter 3.1 of the central section 3 is connected by eight lock connections 4 , and the same number of lock connections 4 at the connection of the circumferential side 3.2 of the central section 3 with the upper frame 2 . Carrying out the key connections 4 is structurally solved in the same way as in the examples in Fig. 1 and 2, i.e., on the vertical ribs 1.1 of the lower frame 1 and on the vertical ribs 2.1 of the upper frame 2 , the first locking part 4.1 is created , which will go into another locking part 4.2 created on the central section 3 . This number of locking joints will provide sufficiently strong connections between the connecting frames 1 and 2 with the central section 3 , so there is no need to further fix the connected sections. Also in this embodiment, the locking connection 4 is created as a single closed, i.e., the second locking section 4.2 on the central section 3 is surrounded by a fixed surface. But even this connection with 16 locking joints does not exclude additional fixation, for example, by welding.

In fig. 7 - 16 depict different versions of the lock connection 4 .

Fig. 7 and 8 depict the performance of a single open lock connection 4 . This single open lock connection 4 is designed so that a slot 6 leads from the second lock part 4.2 on the lower perimeter 3.1 and on the upper perimeter 3.2 of the central section 3 towards the open sides of the central section 3. The first lock section 4.1 on the upper frame 1 and on the lower frame 2 is created as in the previous examples. This slot 6 facilitates the insertion of the second locking parts 4.2 in the first locking sections 4.1 , created on the vertical ribs 1.1 of the lower frame 1 and on the vertical ribs 2.1 of the upper frame 2 .

Fig. 9 and 10 depict the execution of a single closed lock connection 4 , which for connecting the upper frame 2 with the central section 3 is created on the vertical rib 2.1 , moreover, the recess 4.11 of the first lock section 4.1 is made to fit the longer part of the vertical rib 2.1 and the protruding section 4.12 is made in size on the shorter section of the vertical rib 2.1 . Second lock section 4 . 2 is created on the upper perimeter 3.1 of the central section 3 , it is drawn deeper into the wall of the central section 3 (Fig. 9). Also, to connect the lower frame 1 to the central section 3, a lock connection 4 is created on the vertical rib 1.1 of the lower frame 1 , moreover, the recess 4.11 is made to fit the longer section of the vertical rib 1.1 and the protruding section 4.12 on the shorter section of the vertical rib 1.1 . The second locking section 4.2 , created on the lower perimeter 3.1 of the central section 3, is drawn deeper into the wall of the central section 3 (Fig. 10).

Fig. 11 and 1 2 depict the execution of a single open lock connection 4 with the same structural solution, as described for examples in Fig. 9 and 10. The difference of this lock connection is that from the other lock section 4.2 towards the open sides of the central section 3, a slot 6 is created that facilitates the insertion of the second lock section 4.2 into the first lock section 4.1 on the lower frame 1 and on the upper frame 2 .

Fig. 13 and 14 depict the design of a double closed lock connection 4 , which connects the center section 3 with the lower frame 1 and with the upper frame 2 . The structural solution of the double closed lock connection includes the same elements as the solutions described in the previous examples, but on the vertical edge 1.1 of the lower frame 1 and on the vertical edge 2.1 of the upper frame 2 , two first locking sections 4 .1 are included, including a recess 4.11 and protruding section 4.12 . On the connected central section 3 on the lower perimeter 3.1 and on the upper perimeter 3.2 , two second locking sections 4.2 are created one above the other, into which the first two locking sections 4.1 are inserted. If the rectangular combination container will include two double locks on each side on the two lower vertical ribs 1.1 and on the two upper vertical ribs 2.1 , then the total number of lock connections around the perimeter of the combination container will be 32. This version of the lock connection is especially suitable for combination containers of a larger size with greater permissible load.

Fig. 15 and 16 depict the design of the double open lock connection 4 , which connects the center section 3 with the lower frame 1 and with the upper frame 2.1 . Structurally, this is the same solution for the locking connection, as described for the examples in Fig. 13 and 14. The difference between this locking connection 4 is that a slot 6 is created from the second locking section 4.2 towards the open side of the central section 3 , and a slot 7 is made between the two locking sections 4.2 located one above the other. These slots 6 and 7 facilitate the insertion of the second locking sections 4.2 into the first locking sections 4.1 on the lower frame 1 and on the upper frame 2 .

In fig. 17 and 18, a rectangular rectangular combo container 10 is shown, consisting of a central section 3 , a lower frame 1 and an upper frame 2 , the central section 3 being attached to the lower frame 1 and to the upper frame 2 with a single open lock connection 4 . The structural design of a single open lock connection is similar to the design example described and shown in Fig. 7 and 9. But one shorter side of the connected sections 1 , 2 and 3 forms the open side 8. This solution is especially suitable for storing goods on shelves, when the open side 8 decides access to the stored goods. The open side 8 may also be formed on two opposing shorter sides or on adjacent shorter and longer sides, etc. To strengthen the strength of the connected parts 1 , 2 and 3, these sections at points 1 2 are still connected to each other by welding.

Although several options for connecting the lower frame 1 and upper frame 2 with the central section 3 of the combined container have been described and confirmed by drawings, other various combinations are not excluded, for example, one combined container will be connected on the lower frame with the central section by a double closed lock connection, and on the upper frame with a single open lock connection, etc. Even the additional strengthening of the strength of the connected sections, for example, by welding or mechanical connection, is not ruled out.
