Description

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

BACKGROUND

For packaging, articles such as food can be received in a container, for example a tray, a folding box or a carton, wherein the container is closed with a lid after insertion of the article. For example, it is known in connection with folding cartons that the lid is formed with lid elements which are pivoted from outside to inside to close the carton opening, so that the lid elements partially overlap one another in the position closing the carton opening.

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

US 2015/0210442 A1 discloses a food container made of the plant material bagasse. It has a lid and a lower part with a side wall and an outwardly projecting 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. Tabs 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 packaging bottom made of leaf material and a foldable packaging cover made of a recyclable material.

CA 3070825 A1 discloses a removable lid for an open-top container. It comprises a generally planar body formed of resilient material and dimensioned to cover at least substantially an open top of the container. The body is configured to engage corner portions of the container.

SUMMARY

The object of the invention is to specify a packaging for an article and a packaged article, with 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 packaging bottom of a leaf material of a plant, the packaging 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 having recesses.

The packaging cover is arranged on the packaging bottom such that outwardly projecting bottom edge portions (of the bottom edge) engage in respective ones of the recesses of the packaging cover such that the packaging cover is fixed in its relative position with respect to the packaging bottom.

According to a further aspect, a packaged article is provided comprising an article and a packaging, 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 packaging bottom, in particular in the region of the bottom edge portions, in cooperation with the engagement of the bottom edge portions in the recesses of the packaging cover and the increased adhesion to the recesses achieved thereby, an improved fixing of the packaging cover on the packaging bottom can be achieved such that the article remains protected in particular during movement of the packaging. In particular the bottom edge (especially each of the bottom edge portions) can be formed from the leaf material (with a rough surface).

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

The bottom edge portions can engage (from inside) through the corresponding recesses on the packaging cover to the outside (away from the packaging bottom). The packaging cover, when arranged on the packaging bottom, can surround the bottom edge laterally and/or along a bottom edge upper side.

The bottom edge on at least one (first) of the bottom edge portions can comprise an increased protrusion with respect to adjoining further portions of the bottom edge. In other words, at least one of the bottom edge portions can protrude further with respect to the bottom side wall than the further portions of the bottom edge adjoining the bottom edge portion. For example, a protrusion of at least one of the bottom edge portions with respect to the bottom side wall in relation to a protrusion of the further portions of the bottom edge adjoining the bottom edge portion can be increased by at least 10%, in particular by at least 25%.

At least one (in particular each) of the bottom edge portions can (each) be formed as a projection integrally formed on the bottom edge, which in particular engages in at least one of the recesses when arranging the packaging cover on the packaging bottom. The projection can be formed as a continuation of a bottom edge surface.

The bottom edge in the region of at least one (second) of the bottom edge portions and adjoining further portions of the bottom edge can comprise a (substantially) constant protrusion.

In other words, at least one of the bottom edge portions can protrude equally with respect to the bottom side wall as further portions of the bottom edge adjoining the bottom edge portion.

The packaging cover can be arranged (dimensioned and) on the packaging bottom such that side wall portions of the packaging cover are pressed against corner regions of the bottom edge and thereby curved such that in at least one of the corner regions at least one of the bottom edge portions engages in at least one of the recesses.

In other words, the packaging cover can be arranged (dimensioned and) on the packaging bottom such that pressure points and/or pressure regions are formed at corner regions of the packaging and thereby side wall portions of the packaging cover are curved such that in at least one of the corner regions at least one of the bottom edge portions engages in at least one of the recesses. Middle portions of cover side walls can be curved outwardly.

In particular, the packaging cover can be arranged (dimensioned and) on the packaging bottom such that hereby a cover edge contour is curved (outwardly).

At least one of the bottom edge portions can also be arranged in the region of a middle of a bottom edge side, for example in the case of a quadrangular or polygonal configuration of the bottom edge.

It can be provided that at least one (in particular two or three) of cover side walls is free of recesses. Alternatively, at least one (in particular two) of the recesses can be formed on each of the cover side walls.

At least one of the bottom edge portions can be formed along a straight line or comprise a curvature. For example, one of the bottom edge portions can comprise a (substantially) quarter-circular contour.

At least one of the bottom edge portions can engage in two of the recesses. In particular, each of the bottom edge portions can engage in two of the recesses.

The two of the recesses (in particular two of the recesses each) can be arranged in the (each) same corner region of the bottom edge. It can also be provided that two separate projections engage in two recesses in the same corner region.

At least one of the recesses can be arranged on (and/or in the region of) a lug formed on the packaging cover. The lug can be formed as a protrusion/projection of a cover side wall (of the packaging cover). In particular, the lug can continue a cover side wall surface (especially in the case of a three-dimensionally shaped packaging cover). Alternatively, the lug can be formed as a (foldable) flap with respect to a cover upper side (especially in the case of a packaging cover formed in a planar manner). Generally, at least one (or each) of the recesses can be formed within a (corresponding) cover side wall.

The bottom edge portions can be equidistantly arranged around the bottom edge (and the recesses around the packaging cover).

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

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

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

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 packaging bottom (including bottom support surface, bottom side wall and bottom edge) can be integrally formed.

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

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. Additionally or alternatively, the packaging cover can consist of compostable and/or biodegradable material.

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

The three-dimensional packaging bottom can be a container from the following group: tray, plate, cup, tray, plate and bowl.

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

The bottom edge can completely surround and/or encircle the bottom side wall. The bottom edge can be formed, for example, in a ring-shaped manner or so as to surround a quadrilateral (in particular a square or a non-square rectangle).

The inner side of the packaging cover can come into contact with the bottom edge such that a contact line between the packaging cover and the packaging bottom, in particular between the packaging cover and the bottom edge, is a closed curve. Alternatively, the contact line can be interrupted in portions, for example at corner portions of the packaging.

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

The packaging cover can comprise (at least) two, (at least) three, (at least) four, (at least) six or (at least) eight recesses in each of which a bottom edge portion engages.

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

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

DESCRIPTION OF EXEMPLARY EMBODIMENTS

Further exemplary embodiments are explained in more detail below with reference to drawings. In the drawings:

FIG. 1 shows a schematic illustration for producing a packaging for an article;

FIG. 2 shows a schematic detail view of a portion of the packaging;

FIG. 3 shows schematic illustrations of further embodiments of the packaging;

FIG. 4 shows schematic illustrations of further embodiments of the packaging;

FIG. 5 shows schematic illustrations of further embodiments of the packaging with a planar shape or various three-dimensional shapes; and

FIG. 6 shows schematic illustrations of further embodiments of the packaging with a transparent window.

FIG. 1 shows a schematic illustration for producing a packaging for an article (not illustrated). In a partial view (a), a packaging bottom 1 and a packaging cover 5 of the packaging 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 receiving or bottom support surface 2, for example for receiving a food. 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/integrally formed 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 surrounds/encircles the bottom side wall 3.

As illustrated in FIG. 1, the packaging cover 5 has recesses 6 in which corresponding outwardly projecting bottom edge portions 7 of the packaging cover 5 can engage. In this way, the packaging cover 5 is fixed on the packaging bottom 1 and the packaging is correspondingly formed.

For fixing the packaging cover, a detail view of a portion of the packaging is shown in FIG. 2. The packaging cover 5 is arranged encircling the bottom edge 4 and the bottom edge portions 4 engage from inside through the corresponding recesses 6 on the packaging cover 5 to the outside (away from the packaging bottom 1). In particular the rough surface of the leaf material of the packaging bottom 1 is used here such that, together with the engagement of the (rough) bottom edge portions 7 in the recesses 6, an improved fixing of the packaging cover 5 on the packaging bottom 1 is achieved.

As shown in FIG. 3, the bottom edge portions 7 engaging in the recesses 6 can be formed as (protruding) projections 7a (FIG. 3 on the left). Furthermore, the bottom edge portions 7 can also be formed in a non-protruding manner (FIG. 3 on the right). In this case, the bottom edge portions 7 are pressed into the recesses 6 by means of the pressure generated by the arrangement of the packaging cover 5 on the packaging bottom 1.

In particular, as illustrated in FIG. 4, the packaging cover 5 can be dimensioned and arranged on the packaging bottom 1 such that side wall portions of the packaging cover 5 are pressed against corner regions 4a of the bottom edge 4 and thereby curved such that in at least one of the corner regions 4a at least one of the bottom edge portions 7 engages in at least one of the recesses 6. In particular, a lid edge contour 5c (a contour of the (lower) edge of the packaging cover 5) is curved outwardly here (compared to an uncurved initial position of the packaging cover 5 in which the packaging cover 5 is not arranged on the packaging bottom 1). This is illustrated, for example, in a partial view (c) of FIG. 4. In this way, one of the bottom edge portions 7 can engage in one of the recesses 6 each (partial view (a)) or in two of the recesses 6 each (partial views (b) and (c)). Furthermore, the bottom edge portions 7 can be formed so as to protrude with respect to adjoining portions of the bottom edge 4, in particular as projections 7a (partial view (b)), or in a non-protruding manner (partial views (a) and (c)).

Moreover, it can be provided that at least one (in particular two) of the cover side walls 5a is free of recesses 6 (partial view (a)). Alternatively, at least one (in particular two) of the recesses 6 can also be formed on each of the cover side walls 5a (partial views (b) and (c)).

Further embodiments with various shapes of the packaging and arrangements of the bottom edge portions 7 and of the recesses 6 are shown in FIG. 5. For example, the packaging cover 5 can be formed in a truncated pyramid-shaped manner (FIG. 5, left and bottom middle), in a truncated cone-shaped manner (FIG. 5, top middle and top right) or in a planar (flat) manner with lugs 8 (bottom right). If a lug 8 is provided, one of the recesses 6 can be formed in the region of the lug 8. The lug 8 can be formed as a protrusion of one of the cover side walls 5a, so that the lug 8 continues the surface of the cover side wall 5a (cf. FIG. 5, middle). Alternatively, the lug 8 can be formed as a flap which is foldable with respect to a cover upper side 5b (FIG. 5, bottom right).

Furthermore, (additionally or alternatively) at least one of the recesses 6 can be formed in the cover side wall 5a itself (outside a lug 8).

In FIG. 6, further embodiments of the packaging are illustrated in which a transparent window 9 is provided in each case in the packaging cover 5. The window 9 can be provided, for example, on a cover upper side 5b. Furthermore, the window 9 can be formed square or round.

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.
