Description

Technical area

The invention relates to a folding box which is reusable and the possibilities for assembling it.

State of the art

Disposable cardboard boxes are used to transport goods, which are usually disposed of after a single use. Usually they are recycled and used again to make cardboard. This is very uneconomical and unecological. There are problems with the binding, connecting and marking means, such as adhesive tapes, cords, metal clips and stickers, which complicate and make recycling more expensive. In addition, they prevent repeated use of the same packaging, since individual packaging parts are damaged when they are dismantled and transporting the empty, unfolded boxes is uneconomical.

The utility model CN204124496U describes a box with reinforcement at each corner, the reinforcement elements being attached to the opening portion of the box.

GB548495 describes a stacking box made from cardboard. It consists of a base, side walls, an intermediate wall and a lid that is not attached to the box.

EP2161203 (E 13981) describes a stacking box made of cardboard that has a number of crease lines that define a cuboid with a hinged lid. The box is made of corrugated cardboard, with the channels of the corrugated cardboard running in the vertical direction in the side walls used. This packaging is suitable as an archiving box.

The aim of this invention is to produce a box that can be used several times, is easily foldable without the use of special tools, is completely lockable and recyclable so that it can be used for mail transport and possibly sealed.

Description of the invention

The listed deficiencies of the current technical condition are remedied by a folding box for multiple use in the form of a cuboid. It consists of a packaging jacket in the shape of a rectangle and two side walls with locking lugs. The packaging jacket is divided into 5 parts by folding lines: the bottom, 2 opposite side surfaces and the lid, which consists of 2 parts. The crease lines run parallel to the two opposite sides of the packaging jacket. Each of the parts of the packaging jacket has at least 2 blind openings on the outer edges, which serve to accommodate the locking lugs of the side walls. Each side wall has the shape of a rectangle and has at least 4 tabs on the outer edges, at least one on each side. The locking lugs are adapted to the blind openings in the packaging jacket.

The packaging jacket preferably has the shape of a rectangle or square. The individual parts of the packaging jacket are arranged along the longer / one side of the rectangle / square as follows: the first side of the lid, a side wall, base, the second side wall, the second part of the lid. These parts are divided by crease lines that run parallel to the shorter / second side of the rectangle / square. The two cover parts are preferably the same size. The individual parts of the packaging jacket and the side walls are designed in such a way that after inserting the side walls and bending the packaging jacket along the crease lines, they form a cuboid.

The blind openings in the packaging jacket intended for the latching lugs of the side walls are preferably 5 mm to 10 mm away from its free edges. All blind openings are placed on one side of the packaging jacket. After assembly, this side, together with the side walls, forms the inner surface of the box. The blind openings preferably have a rectangular cross section in a plane parallel to the packaging jacket. Each bottom part and the adjacent side parts have at least 2 blind openings, on each free edge, roughly in the middle of their length. Each part forming the lid has at least 2 blind openings, one on each opposite free edge of the part, approximately midway along its length.

Instead of blind openings, the cover can have through openings for inserting the stacking lugs of the stackable side walls. Furthermore, the bottom can also contain complementary blind or through openings which are located on the other side of the packaging jacket (which, when folded, forms the outer wall of the box). This arrangement is advantageous for stacking folded boxes where the stacking tabs on the sides of the first box fit into the complementary blind / through openings in the bottom of the second box being stacked on top of the first box.

The free edge of the part is the edge of the part that is not formed by a crease line, but by the edge of the packaging jacket. The width of the part results from the length of the crease line and the height of the part results from the thickness of the packaging jacket.

The essence of the box in its simplest form lies in the fact that the box is only folded and held together by shaped latching lugs and fixing latching recesses into which these latching lugs fit. After opening, the box can be dismantled very simply and easily and transported to the place of re-assembly and reuse in individual panels to save space.

In another embodiment, the blind openings of the lid of the packaging jacket are replaced by through openings and the bottom of the box also has at least four through openings which are located vertically below the through openings of the lid when the box is folded. In this embodiment variant, the latching lugs of the side walls for insertion into the cover are replaced by longer stacking lugs that are complementary to the through openings of the cover. When the box is folded, the stacking tabs protrude from the through openings in the lid.

In a simple embodiment variant, the latching and / or stacking lugs are an integral part of the side wall. In another embodiment, the latching and / or stacking lugs can be attached to the side wall by connecting elements.

It is advantageous if the connecting elements for fastening the latching and / or stacking lugs to the side wall have teeth and tongs that fit into one another.

In this embodiment, the box can contain at least one or more openings for fastening seals on one or both cover parts. Preferably there are two openings in the free corners of the cover on each part of the cover.

According to the present invention, the individual parts of the box, ie the packaging jacket and / or the side wall, can consist of cardboard, corrugated cardboard, double cardboard or honeycomb cardboard, with a thickness of 0.5 cm to 3 cm, preferably 0.6 cm to 1.6 cm cm. The wall thickness of the box and the selection of a suitable material depend on the size of the box and the intended content.

In an advantageous embodiment, the kinking grooves of the packaging jacket have a V-shaped cross section with an angle of 90 °, in particular if the material from which the box is made is a honeycomb panel.

In order to strengthen the box and extend its service life, the latching and / or stacking lugs can be provided with an edge or reinforced by penetrating them with solidifying solutions.

The through openings and / or the blind openings of the packaging jacket can be reinforced by penetrating with solidifying solutions such as water glass.

If it is a box with larger dimensions, the packaging jacket with reinforcements to strengthen the kink grooves and / or reinforcements to strengthen the free corners of the lid and / or with a stiffening element to strengthen the connection of the bottom to the side wall and / or to Reinforcement of the connections of the side walls and / or the side wall to the floor may be provided. The reinforcements, edges and stiffening elements can be made of plastic, metal or a combination thereof. Reinforcements for strengthening the free corners of the lid can include a groove which can receive a binding element or a seal to avoid the surface of the box lid.

All types of reinforcements, stiffening elements and edges include connecting means, preferably in the form of teeth and tongs for fastening to the packaging jacket and / or to the side wall. If necessary, the edges include wedges for piercing the integrated side wall tabs.

All types of reinforcements, stiffening elements, noses and edges contain connecting elements for connection to the packaging jacket and / or to the side walls and the packaging jacket and the side walls have fastening holes for fastening the reinforcements, edges, noses and reinforcing elements by connecting elements, which are preferably teeth and Have pliers for mutual connection.

Within the scope of this invention there is a type of box which has a side wall with an adapted latching nose which can be sunk into a blind opening in the side wall or in the bottom. This locking lug is equipped with a countersink element which is located on the shorter side of the locking lug (on the side of the lug). In this case, the respective blind opening of the side wall or of the bottom is provided with a complementary recess in order to close the recess element in this recess when the box is assembled sink. The lowering element can be an integral part of the latching lug or the lowering element can be connected to the latching lug.

According to the present invention, the box is suitable for multiple uses. It is used many times and is only recycled after obvious and irreparable damage.

The individual exposed parts of the box, which can be damaged by their frequent use (protrusions, technological openings) and which weaken the wall of the box itself, can advantageously be reinforced in various ways, for example by penetrating them with solidifying solutions (water glass, etc.) , Reinforcements made of other materials (metal, plastic, etc.) or the production of the individual exposed parts directly from a stronger material - plastic, metal, etc. These foreign parts are simply torn from the cardboard material (honeycomb cardboard, cardboard or corrugated cardboard) if the box is damaged during recycling and recycled accordingly.

Some surfaces of the box can advantageously be provided with a special layer of varnish, on which the labels with the accompanying data of the shipment are stuck, which can then be easily removed from this area, e.g. by simply peeling off, in the case of an inscription by erasing with thinner. According to the invention, in the folded state, the box can be provided with a lacquer coating on the outside of the side walls and / or the lid in order to make it easier to remove the labels with the associated data on the shipment.

The lid of the box can simply be closed loosely, closed with a string or with adhesive tape. It appears advantageous to close the cover with a seal which guarantees the integrity of the shipment or contains a code or chip in which the complete data of the shipment are stored.

Due to the fact that the boxes can be made modular, it is possible to replace the damaged panels individually in the event of damage without having to replace the entire box.
