Title:

container

The invention relates to a container with a base, two front surfaces arranged perpendicular to the base and two side surfaces arranged perpendicular to the base.

Such containers made of corrugated cardboard are used extensively as packaging for a wide variety of materials, including office supplies such as drawing pads, paint boxes, fountain pens, colored pencils and exercise books.

A well-known cut for producing such a container from corrugated cardboard is known as FEFCO 0200 and 0304. Such containers have a divided base, which is usually closed with an adhesive strip. However, this leads to unevenness in the base area of the packaging and thus to problems when transporting the packaging. However, unevenness in the base area leads to major problems, particularly when transporting the container on roller conveyors, which is very often necessary within the company.

The invention is therefore based on the object of proposing a container that is easy to manufacture and has a flat bottom.

This task is solved in a container of this type in that front and side surfaces are arranged around a base surface and the front and side surfaces are connected to one another via corner parts in such a way that when the front surfaces are erected, the side surfaces are also erected.

Front and side surfaces are opposite side walls of the container, regardless of the dimensions of the side walls.

The inventive design of the container ensures that the bottom surface of the container is completely flat and the special corner parts enable the container to be quickly and easily erected manually or automatically from a cut piece.

It is advantageous if the container can be made from a corrugated cardboard blank. Containers made from corrugated cardboard are easy to recycle and can be used as disposable or reusable containers. Manufacturing from a blank offers the advantage that the blanks are easy to transport and the containers are only made by erecting them shortly before they are filled. In this case, a single blank is sufficient to make the container. A lid can be made from another blank in the usual way.

A particularly low level of waste is achieved by having the front and side surfaces of the cut adjacent to the base surface and the corner parts arranged between the front and side surfaces.

In order to ensure that the container can be erected as easily as possible, it is suggested that the corner parts are perforated on their symmetry line running from the respective corner of the base surface (2). The perforation facilitates the bend on this symmetry line, which is necessary to erect the container.

It is also advantageous if one half of the corner piece is glued to the side surface. To glue, the front sides and the corner pieces are folded over onto the remaining cut. Once the glue has set, the

If the front surfaces are raised, the side surfaces automatically rise as well.

In order to keep the container in shape when it is upright, the side surfaces have tabs on their upper edge that can be folded around the corners into the container. The tabs attached to the inside of the container prevent the front surfaces from bending back towards the base.

A right-angled bend between the side surface and the flap is achieved by placing a perforated double line between the side surface and the flap. The perforation makes it easier to bend and results in a flat upper edge of the container in the area of the side surfaces.

It is advantageous if the tabs have projections that engage in slots in the front sides or in the base. Such projections slide into slots on the sides of the front surfaces when the tab is folded over, for example, and thus hold the tabs firmly in the folded position.

Gripping the front sides to erect the container is made easier by the fact that the upper edges of the front sides have recesses. Especially when the upper edges of the front sides are close to one another in the folded, glued state, such recesses make it easier to grip under the front side to erect the container.

Finally, it is suggested that the container has a modular dimension that is adapted to a Euro plate. This means that different

Packing units can be combined on a Euro pallet without individual packages protruding beyond the basic dimensions of the Euro pallet.

An embodiment of the invention is shown in the drawing and is described in more detail below.

It shows:

Figure 1 shows a blank for a container according to the invention
and

Figure 2 shows a blank for a container lid.

Figure 3 shows a blank for a container according to the invention that can be used as a basket

The blank 1 shown in Figure 1 has a rectangular base surface 2, on whose shorter sides 3 and 4 essentially rectangular front surfaces 5 and 6 adjoin, while on its longer sides 7 and 8 rectangular side surfaces 9 and 10 adjoin. Square corner parts 11 to 14 are arranged in the corners between the front surfaces 5, 6 and the side surfaces 9, 10, so that the base surface 2, front surfaces 5, 6, side surfaces 9, 10 and corner parts 11 to 14 together cover an essentially rectangular surface. Between the front and side surfaces and the corner parts and between the front and side surfaces and the base surface, grooves are provided which make it easier to erect the front surfaces 5, 6 and side surfaces 9, 10.

Circular cutouts are provided at the four corners 15 to 18 of the rectangular base surface 2, which also facilitate the erection of the front surfaces 5, 6 and side surfaces 9, 10. A perforated symmetry line 19 to 22 runs from each of these corners 15 to 18 to the outermost corner 23 to 26 of the corner parts 11 to 14.

On the side surfaces 9, 10, on the side opposite the sides 7, 8 of the base surface 2, a tab 27, 28 is arranged, which extends over the entire side of the side surfaces 9, 10. A perforated double line 29, 30 runs between the side surfaces 9, 10 and the tabs 27, 28 to make it easier to fold the tabs 27, 28. Projecting parts 31 to 34 extending beyond the longitudinal extent of the tabs 27, 28 are arranged in such a way that, after the container has been erected from the blank 1 and after the tabs 27, 28 have been folded into the container, they can engage in slots 35 to 38 between the end faces 5, 6 and the corner parts 11 to 14.

The end faces 5, 6 each have semicircular recesses 39, 40 on the side opposite the bottom edges 3, 4, which serve as finger holes when setting up the container.

As is easily apparent to the person skilled in the art, the dimensions of the cut pieces can be easily varied so that containers with different heights, depths and widths can be created. Preferably, however, the dimensions are set so that the dimensions of the container or different containers allow a seamless arrangement of several containers on a Euro pallet.

In the described cutting, to produce the container, the front surfaces 5, 6 with their adjacent corner parts 14, 11 and 12, 13 are folded onto the base surface 2 and the side surfaces 9, 10 and the part of the corner parts 10 to 14 lying between the symmetry line 19 to 22 and the side surfaces 9, 10 is glued to the side surfaces 9, 10.

The blank prepared in this way is easy to transport and is formed into a container by the user by lifting the end faces 5, 6. The recesses 39, 40 make it easier to reach under the end faces 5 and 6 in order to be able to lift them more easily. In order to fix the container in its upright form, the tabs 27, 28 are folded around the corner parts 11 to 14 into the container, whereby a right-angled bend is created on each line of the perforated double lines 29, 30. The tabs 27, 28 are firmly anchored in the container by pressing the projections 31 to 34 into the slots 25 to 38 in the end faces 5, 6.

The container is then erected in this way and is ready for filling and can then be closed with a lid that can be put on. An example of how to make a lid is shown in the blank in Figure 2. This blank is known from the Fefco code 0304 and a more detailed explanation of the lid construction is therefore unnecessary. \

While plastic trays without handles were previously used to package strawberries, plums and cherries, the new packaging shown in Figure 3 is a 4-point glued packaging made of corrugated cardboard with an attached handle for manual erection. The packaging

corresponds essentially to that shown in Figure 1 and is made from the cut shown in Figure 3 by folding up the side parts, whereby the corner parts located between the side parts move to the inside of the container and are secured in the container using the foldable tabs at the top of the two side parts. To do this, the tabs are folded over and pressed into slots between the front sides and the corner parts.

A carrying handle 41 is provided on a front side 42 of the blank and is preferably connected to the blank via a perforation. This carrying handle 41 can simply be torn off the blank. The side parts 43, 44 of the carrying handle are then folded onto the middle part 45 and the carrying handle 41 is then formed into an arch, the ends of which can be inserted into slots 46, 47 at the upper end 48, 49 of the side parts.

If the ends of the handles are passed through the slot 46, 47 at the upper end of the side parts before folding over the tabs 50, 51 attached to the side parts, the end of the handle can be placed around the ends of the folded corner parts in such a way that when the tab 50, 51 is folded over, the handle 41 is attached to the rest of the container.
