Field of technology

The invention relates to a reusable folding box and to a method for folding it.

Prior art

Disposable paperboard boxes are used to transport the goods, which are destroyed after one use. They usually go to separate waste, where they are recycled and reused for cardboard production. It is very uneconomical and unecological. Problems also arise with binding, fastening and marking means (adhesive tapes, twine, metal clips and stickers), which complicate and make the whole system of separation and recycling more expensive. In addition, they do not allow multiple use of the same box, as disassembly damages the individual parts and transports undecomposed empty boxes is uneconomical.

Utility model CN204124496U describes a service box in each corner, the service being attached to the opening part of the box.

GB548495 describes a collapsible box which is made of cardboard and comprises a bottom, side walls and a partition. The box is without the lid attached.

EP2161203 (E13981) describes a cardboard storage box which is formed from a board provided with a plurality of folding lines which define a rectangular block with a hinged lid. The box is made of corrugated cardboard, with the corrugated cardboard channels running in the side walls in position when used in the vertical direction. This box is suitable as an archive box.

The object of the present invention is to produce a box which can be used multiple times, can be easily folded, without the use of special tools, should be completely sealable so that it can be used in postal transport, recyclable and possibly sealable.

The essence of the invention

These shortcomings are addressed by a reusable rectangular hexagonal folding box, the essence of which is that it comprises a rectangular cladding board and two side panels with protrusions, where the cladding board is divided into five bottom parts, two opposite side walls by folding grooves, and lid consisting of two parts. The folding grooves are formed parallel to the two opposite sides of the wrapping plate where each part of the wrapping plate comprises at least two blind holes formed at the free edges of the wrapping plate adapted to receive the sidewall protrusions. Each sidewall has the shape of a rectangular square, and comprises at least four protrusions spaced at the outer edge of the sidewall at least one on each side. The side protrusions are adapted to fit into the blind holes of the wrapping plate.

The wrapping plate is preferably rectangular or square in shape. The individual parts of the wrapping plate are arranged along the longer / one side of the rectangle / square in order: the first part of the lid, one side wall, the bottom, the second side wall and the second part of the lid. The individual parts are separated by folding grooves arranged parallel to the shorter / second side of the rectangle / square. The first and second lid parts preferably have the same dimensions. The dimensions of the individual parts of the wrapping plate and the sidewalls are such that, after inserting the sidewalls and bending the wrapping plate along the folding skins, they form a rectangular hexagon.

The blind holes for inserting the sidewall protrusions formed in the wrapping plate are preferably located in the wrapping plate 5 mm to 10 mm from its free edges. All openings are located on one side of the wrapping plate, which, when folded together with the sidewalls, defines the inner space of the box. The blind holes preferably have a rectangular cross-section in a plane parallel to the coating plate. Each part forming the bottom and opposite side walls comprises at least 2 blind holes, one at each free edge of the part, approximately in the middle of its length. Each lid-forming part comprises at least 2 blind holes, one at each opposite free edge of the part, approximately in the middle of its length.

Instead of blind holes, the lid may include through holes for inserting sidewall stacking protrusions. Also, the bottom may include complementary blinded or continuous openings formed on the other side of the wrapping plate (which, when folded, forms the outer wall of the box). This arrangement is advantageous for stacking stacked boxes, where the stacking protrusions of the sides of the first box fit into complementary location of the blind / through holes of the bottom of the second box located on the first box.

The free edge of the part is the edge of the part which is not formed by the folding groove but is formed by the edge of the wrapping plate. The width of the part is given by the length of the folding groove and the height of the part is given by the thickness of the wrapping plate.

The essence of the box in the simplest design also lies in the fact that the box folded only by being held together by shaped protrusions and fixing holes into which these protrusions fit. Once opened, a check is possible

SK 50029-2020 A3 disassembly is very easy and undemanding and it can be transported very economically in individual boards to the place of reassembly and reuse.

According to another embodiment, the blind openings of the lid of the wrapping plate are replaced by through holes and wherein the bottom further comprises at least four through holes formed vertically below the through holes of the lid when the box is folded. In this embodiment, the side protrusions for engaging the lid are replaced by stacking protrusions complementary to the continuous openings of the lid. When the box is folded, the stacking protrusions extend beyond the continuous openings of the lid.

According to a simple embodiment, the protrusions and / or stacking protrusions are integrally connected to the sidewall. According to another embodiment, the protrusions and / or stacking protrusions can be attached to the side panel by connecting means.

It is advantageous if the connecting means for attaching the protrusions and / or stacking protrusions to the sidewall are teeth and pliers which are adapted to cooperate with one another.

The box according to this embodiment may comprise at least one or more openings for sealing the seal (s) on both parts of the lid. Preferably two openings on each part of the lid located in the free corners of the lid.

The individual parts of the box according to the invention t. j. the wrapping board and / or side panel may be made of cardboard, paperboard, double board or paper honeycomb 0.5 cm to 3 cm thick, preferably 0.6 cm to 1.6 cm, even more preferably 0.6 to 1.6 cm, preferably 0.6 cm, 1 cm, 1.6 cm. The wall thickness of the box as well as the choice of a suitable material depends on the size of the box and the intended contents of the box.

According to a preferred embodiment, the folding grooves of the packaging plate have a V-shaped cross-section at an angle of 90 °, in particular if the material from which the box is made is a honeycomb.

To reinforce the box and prolong its service life, the protrusions and / or stacking protrusions can be provided with a rim and / or reinforced by penetrating solidifying solutions.

The continuous openings and / or even the blind openings of the coating plate can be reinforced by penetration with solidifying solutions, such as water glass.

The wrapping plate may be provided with reinforcements to reinforce the folding grooves and / or reinforcements to reinforce the free corners of the lid and / or to tie the bottom to the sidewall and / or to reinforce the sidewall to the sidewall and / or the bottom, in particular if it is a box of larger dimensions. The covers, hems and ties can be made of plastic, metal or a combination thereof. The reinforcements for reinforcing the free corners of the lid may comprise a groove where it is possible to accommodate the binding means or seal so that it does not interfere with the plane of the surface of the box.

All types of reinforcements, ties and hems comprise connecting means, preferably in the form of teeth and pliers, for attachment to the casing plate and / or sidewall, and optionally the hems further comprise wedges for impact with integrally connected sidewall projections.

All types of reinforcements, ties, external protrusions and flanges comprise connecting means for connection to the wrapping plate and / or sidewalls and the wrapping plate and sidewalls comprise mounting holes for fixing the reinforcements, flanges, protrusions and straps by fastening means which are preferably formed by teeth and clamps for their interconnection.

Also within the scope of the present invention is a box that includes a sidewall that may have one of the sidewall protrusions adapted to fit into a blinded sidewall or bottom opening, and the protrusion is provided with a plug member located on the shorter side of the protrusion. In this case, the respective blind opening of the side wall or bottom is provided with a complementary recess for fitting the plug-in element into this recess when folding the box. The plug-in element may be integrally connected to the protrusion or the plug-in element may be connected to the protrusion.

The box according to the invention is suitable for multiple use. This is used multiple times and goes into recycling only after obvious and irreparable damage.

The individual exposed parts of the box, which are at risk of damage during repeated use of the box (protrusions, technological openings), which weaken the wall of the box itself, can be advantageously reinforced in several ways, e.g. penetration by solidifying solutions (water glass, etc.), reinforcements from other materials (metal, plastic, etc.), or the individual exposed parts are directly made of a stronger material - plastic, metal, etc. After foreigning the box, these foreign parts are simply torn out of the box material (paper honeycomb, cardboard or paperboard) and go to their own recycling.

Some areas of the box can advantageously be painted with a special layer - varnish, on which the accompanying data on the shipment are glued and which are easily removed from this area, e.g. by simple detachment, in the case of an inscription by erasing with thinner.

The box according to the invention can be provided with a lacquer coating on the outer part of the sides and / or the outer part of the lid of the box in the folded state for easier removal of the labels with the accompanying data of the consignment.

SK 50029-2020 A3

The lid of the box can simply be loosely closed, tied with rope or adhesive tape. It seems advantageous to close the lid with a seal, which guarantees the integrity of the consignment, or contains a code or chip in which the complete data on the consignment are stored.

Due to the fact that the boxes can be manufactured modularly, it is possible to replace the damaged boards individually in case of damage, without the need to replace the whole box.
