Description

The invention relates to a packaging for an article and to a packaged article.

BACKGROUND

For the purpose of packaging, articles such as, for example, foodstuffs can be accommodated in a container, for example a tray, a folding box or a cardboard, wherein the container is closed with a lid after the article has been introduced. For example, it is known in connection with folding cartons that the lid is formed with lid elements which are pivoted from the outside inward in order to close the cardboard opening, such that the lid elements partially overlap one another in the position in which they close the cardboard opening.

Various packaging materials for foodstuffs are known, for example composed of paper or cardboard (cf., for example, DE 10 2011 015 331 A1).

US 2015/0210442 A1 discloses a foodstuff container composed of the plant material bagasse. It has a lid and a lower part with a side wall and an outwardly protruding flange. The lid flange and the lower part flange touch one another at the edge of the container when the lid and the lower part are in contact. Flaps on the flanges on opposite sides of the container hold the lid and the lower part together.

US 2023/0278769 A1 discloses a packaging for an article. It consists of a packing bottom composed of leaf material and a foldable packaging cover composed of a recyclable material.

SUMMARY

The object of the invention is to specify a packaging for an article and a packaged article, by means of which an improved fixability of the packaging cover on the packing bottom is made possible and in this way a safe transport of the packaged article is supported.

The object is achieved by means of a packaging for an article and a packaged article according to the independent claims. Embodiments are the subject matter of dependent subclaims.

According to one aspect, a packaging for an article is provided which comprises:

• • a three-dimensionally shaped packing bottom of a leaf material of a plant, the packing bottom being adapted to receive an article to be packaged and comprising: a bottom support surface, a bottom side wall surrounding the bottom support surface, and a bottom edge arranged at an end of the bottom side wall, the end being distal with respect to the bottom support surface, wherein the bottom edge protrudes outwardly from the bottom side wall, and
  • a packaging cover with inwardly protruding flaps.

The packaging cover is arranged on the packing bottom such that the flaps and an inner side (or a further portion of the inner side) of the packaging cover at least partially encompass the bottom edge, so that the packaging cover is fixed in its relative position with respect to the packing bottom.

According to a further aspect, a packaged article is provided with an article and a packaging according to at least one of the preceding claims, wherein the article is packaged by means of the packaging such that the article is arranged on a bottom support surface of the packaging and covered by means of the packaging cover.

By means of the rough surface of the leaf material of the packing bottom, in interaction with the encompassing of the bottom edge by the flaps protruding inwardly (into the center of the packaging cover, in particular in the direction of the packing bottom) and the inner side (of the side of the packaging cover facing the packing bottom and/or the article) of the packaging cover, an improved fixing of the packaging cover on the packing bottom can be achieved, so that the article remains protected in particular during movement of the packaging. In particular, gripping forces formed by the encompassing, which are imparted via contact surfaces of the flaps and the inner side of the packaging cover on the packing bottom, can be supported by means of the increased roughness on the contact surfaces.

The bottom edge can in particular be arranged and/or fixed at least partially between the flap and the inner side of the packaging cover. In particular, the packaging cover can be dimensioned with respect to the packing bottom such that the flaps together with the inner side of the packaging cover (at least partially) encompass the bottom edge. In particular, the bottom edge can be formed from the leaf material (with a rough surface).

The packaging cover can for example comprise two, three, four or more than four flaps. The flaps can be arranged in pairs opposite on the packaging cover with respect to the packing bottom.

A fixing of the packaging cover in its relative position with respect to the packing bottom can in particular comprise a restriction of the relative movability of the packaging cover with respect to the packing bottom, wherein a small play can be possible.

At least one (first) of the flaps can be formed as a foldable projection formed on the edge of the packaging cover.

The projection can be formed on the packaging cover along a folding edge. In particular, the projection can be formed in one piece on the packaging cover.

The projection can be partially glued to the inner side (7) of the packaging cover.

In particular, the projection (and/or at least one further projection) can each comprise a central portion and lateral portions, wherein the lateral portions can be glued to the inner side of the packaging cover and the central portion can be free of gluing such that the central portion protrudes further (than the lateral portions) with respect to the inner side of the packaging cover. Additionally or alternatively, for the projection (and/or the at least one further projection), the central portion can be glued to the inner side of the packaging cover and the lateral portions can be free of gluing such that the lateral portions protrude further (than the central portion) with respect to the inner side of the packaging cover.

Additionally, the lateral portions can be glued such that the lateral portions comprise an additional offset directed in the direction of the central portion with respect to the inner side of the packaging cover.

In addition, the projection (and/or at least one further projection) can be free of gluing overall.

At least one (second) of the flaps can be formed as a tongue which is formed by means of an incision in the packaging cover and which is in particular foldable and/or foldable with respect to the packaging cover.

The incision can for example be (substantially) arcuate such that in particular a (substantially) circular segment-shaped tongue results.

By means of folding and/or folding the tongue, a recess can be formed within which in particular the bottom edge can be encompassed. The recess can be delimited by the folding edge and the incision.

The inner side of the packaging cover can completely cover an upper side of the bottom edge when arranging the packaging cover on the packing bottom. In this way, the contact surface between the packing bottom (in particular bottom edge) and the packaging cover can be increased.

At least one of the flaps can be formed (substantially) with a circular segment shape (a partial circular surface which is delimited by a circular arc and a circular chord). The circular chord can lie on the folding edge (between flap and remaining packaging cover).

At least one of the flaps can also be formed with a (substantially) rectangular shape. Additionally, at least one of the flaps (at least one projection) can be formed with a (substantially) rectangular base surface and a circular segment-shaped portion in the central portion of the projection.

The packaging cover can be three-dimensionally shaped or flat.

For three-dimensional shaping, the packaging cover can be folded and/or inserted and/or glued. In particular, the packaging cover can be a folding cover.

The packaging cover can be formed to be planar, cube-shaped, cuboid-shaped, prism-shaped, pyramid-shaped, truncated pyramid-shaped, cone-shaped, truncated cone-shaped or cylindrical.

The leaf material can be a palm leaf material, for example a cutting of a palm leaf. The palm leaf material can be an Areca palm leaf material.

The leaf material can be a pressed and/or glued leaf material. In this way, the surface roughness can be further increased. For example, the packaging bottom can be produced by means of molding in a molding tool using pressure and temperature.

The leaf material can be produced from a single leaf or a plurality of leaves, in particular a palm leaf or palm leaves. The packing bottom (including the bottom support surface, the bottom side wall and the bottom edge) can be formed in one piece.

In one embodiment, a surface-side coating can be provided on the packing bottom. The coating can be made of a natural, plastic or plastic material, which is optionally biodegradable and/or compostable. Alternatively, the packing bottom can also be uncoated.

The packing bottom can be a container from the following group: tray, plate, cup, tray, plate and bowl.

The bottom edge can comprise rectilinear and/or curved portions (for example at corners of the bottom edge).

The bottom edge can completely delimit and/or encircle the bottom side wall. The bottom edge can for example be formed annularly or delimiting a quadrangle (in particular a square or a non-square rectangle).

The packaging cover can be uncoated. Alternatively, a material coating can be provided, in particular on the inner side of the packaging cover.

The packaging cover can consist of recycled and/or recyclable material. In addition, the packaging cover can consist of compostable material.

The packaging cover can also be produced from paper or a cardboard material, wherein a material coating can optionally be provided.

The inner side of the packaging cover can come to rest on the bottom edge such that a contact line between the packaging cover and the packing bottom, in particular between the packaging cover and the bottom edge, forms a closed curve. Alternatively, the contact line can be partially interrupted, for example at corner portions of the packaging.

Furthermore, the inner side of the packaging cover can come to rest on the bottom edge such that a contact surface between the packaging cover and the packing bottom, in particular between the packaging cover and the bottom edge, forms a perforated surface (surface genus 1).

The packaging cover can be formed to be at least partially (or completely) transparent. For example, the packaging cover can comprise a transparent window (composed of translucent material) (and otherwise be formed to be non-transparent/opaque). The window can be arranged on an upper side of the packaging cover. The window can have a square, rectangular, circular, oval or polygonal shape.

The article can be, for example, a foodstuff/food product. Alternatively, the article can also be a non-food article, for example an item of clothing.

FIG. 1 shows a schematic illustration for producing a packaging for an article (not illustrated). In a partial view (a), the packaging bottom 1 and the packaging cover 5 are illustrated separately; in a partial view (b), the placing of the packaging cover 5 onto the packaging bottom 1 is illustrated; and in a partial view (c), the produced packaging is illustrated. The packaging bottom 1 forms a receptacle for the article in the region of a bottom receptacle or bottom support surface 2, for example for accommodating a foodstuff/food product. The bottom support surface 2 is surrounded by a bottom side wall 3 which, in the embodiment illustrated, extends obliquely upward proceeding from the bottom support surface 2.

A bottom edge 4 is arranged at an end of the bottom side wall 3, the end being distal with respect to the bottom support surface 2, wherein the bottom edge protrudes outwardly. The bottom edge 4 completely delimits/encircles the bottom side wall 3.

For forming the packaging, the packaging bottom 1 is assigned the packaging cover 5 which, according to FIG. 1, is folded by means of folding flaps 8 to form a three-dimensional (non-planar) folding cover. The folding flaps 8 can be glued to (folding flap) portions of the inner side 7 of the packaging cover.

Furthermore, flaps 6 are formed on the packaging cover 5 as projections 6a which are formed on the edge, wherein the projections are foldable with respect to the packaging cover 5 along a folding edge and protrude inwardly (are folded inwardly) for producing the packaging.

For this purpose, FIG. 2 shows a schematic detail view of a portion of the packaging. The packaging cover 5 is arranged on the packaging bottom 1 such that the flaps 6 or projections 6a and the remaining inner side 7 of the packaging cover partially encompass the bottom edge 4, so that the packaging cover 5 is fixed in its relative position with respect to the packaging bottom 1. In particular, the rough surface of the leaf material of the packaging bottom 1 is used here, so that, together with the encompassing of the bottom edge 4 by the flaps 6 and the inner side 7 of the packaging cover, an improved fixing of the packaging cover 5 on the packaging bottom 1 is achieved.

The projection 6a is partially glued to the inner side 7 of the packaging cover. For this purpose, FIG. 3 shows a schematic illustration of the packaging cover 5 with a detail view of the projection 6a. The projection 6a comprises a central portion 6c and two lateral portions 6d. The lateral portions 6d are glued to the inner side 7 of the packaging cover (for example at gluing surfaces 6e) and the central portion 6c is free of gluing such that the central portion 6c protrudes further (than the lateral portions 6d) with respect to the inner side 7 of the packaging cover. The glues counteract forces (for example imparted by the packing bottom 1 and/or along the folding edge with the rest of the packaging cover 5) on the projection 6a, so that only the central portion 6c protrudes and can encompass the bottom edge 4. Additionally, the lateral portions 6d can be glued such that the lateral portions 6d comprise a laterally inwardly directed offset and the central portion additionally protrudes.

In FIG. 4, a corresponding embodiment is shown from below at the top left. In a further embodiment, which is shown at the top right, the central portion 6c is glued to the inner side 7 of the packaging cover and the lateral portions 6c are free of gluing such that the lateral portions 6d protrude further with respect to the inner side 7 of the packaging cover than the central portion 6c. Further projections can also be completely free of gluing (see for example the lower projection 6a in FIG. 4 at the top right.

Further embodiments in which the packing bottom 1 and the packaging cover 5 comprise a circular base surface are shown at the bottom in FIG. 4. In particular, the packaging cover 5 can be formed to be cone-shaped (bottom left) or truncated cone-shaped (bottom right). In FIG. 4 at the bottom left, the projections 6a are formed with a circular segment shape. In FIG. 5, the embodiments illustrated at the bottom in FIG. 4 are shown in a further perspective view.

FIG. 6 illustrates further embodiments of the packaging in which a transparent window 9 is provided in each case in the packaging cover 5.

FIG. 7 shows a schematic illustration for producing a packaging for an article in a further embodiment. In this case, the flaps 6 are formed as tongues 6b which are formed by means of incisions in the packaging cover 5 and which are foldable with respect to the packaging cover 5. In a partial view (a), the packaging bottom 1 and the packaging cover 5 are illustrated separately; in a partial view (b), the placing of the packaging cover 5 onto the packaging bottom 1 is illustrated; and in a partial view (c), the produced packaging is illustrated.

By folding the tongues 6b, recesses 6f are formed in each case in the packaging cover 5 within which the bottom edge 4 can be encompassed. For this purpose, FIG. 8 shows schematic illustrations of the packaging in various views (a), (b) and (c). As shown in the detail view at the top right, the flap 6 or the (downwardly folded) tongue 6b and the inner side 7 of the packaging cover encompass the bottom edge 4. The upper side of the bottom edge 4 is covered by the inner side 7 of the packaging cover.

FIG. 9 shows a schematic illustration of the flaps 6 of the packaging cover 5. The tongue 6b is folded downwardly and in a plan view is thus substantially concealed by the bottom edge 4 which is visible in the plan view within the recess 6f. Finally, FIG. 10 shows further embodiments in which transparent windows 9 are additionally provided.

Furthermore, combinations of projections 6a and tongues 6b can be provided in the same packaging cover 5 (not illustrated).

The features disclosed in the preceding description, the claims and the drawing can be significant both individually and in any desired combination for the realization of the various embodiments.
