Description

Description: The present invention relates to a sliding sleeve, a sliding box and a flat blank for folding a sliding sleeve. Such a sliding box can be used in the food industry, among others.

Ready meals and frozen foods have their place in our daily life. However, it is no longer just a matter of quickly satisfying your hunger during your lunch break. Rather, expectations increase both in terms of the quality and presentation of the product and of its packaging, particularly with regard to handling and environmental friendliness. Usually, the shelves of the food markets contain lasagna and co. Packed in PET trays, sealed with a plastic film and further packed in a cardboard sleeve or cardboard box. Before consumption, the carton must first be removed, the film pierced, the meal heated in a (microwave) oven and then removed from the oven while still hot. Finally, the film, which is now covered with hot steam and sauce splashes, is removed from the PET tray. Both when the hot food is removed from the oven and when the film is put on the PET tray, there are easily problems such as burns and splashes on clothing. At the end of the meal, a dirty plastic film and a stiff PET bowl with food residues must be disposed of in addition to the cardboard outer shell. On the one hand, this is not very convenient because plastic and cardboard usually have to be disposed of separately, on the other hand, the PET bowl takes up an enormous volume in the trash can, so that it is filled quickly.

The object of the present invention is to provide an alternative packaging for snacks and meals, which enables improved handling for the consumer. An additional optional task is to provide environmentally friendly packaging.

The object is achieved by a sliding sleeve comprising a ceiling, a floor, a first side wall and a second side wall, which are articulated to one another to form a sleeve. The ceiling is divided into a first ceiling part adjoining the first side wall, a second ceiling part adjoining the second side wall and a third ceiling part lying between the first and the second ceiling part with two free outer edges. The third ceiling part is articulated to the first ceiling part via a first articulation with a first articulation axis and is articulated to the second ceiling part via a second articulation with a second articulation axis.

The ceiling, floor, first side wall and second side wall are connected in an articulated manner via articulated connections which each have an articulation axis. Are two elements of the sliding sleeve (elements: ceiling, floor, first side wall and second side wall), such as first side wall and floor, connected to one another via an articulated connection, these two elements can be moved towards or away from one another about the articulation axis of the articulated connection.

Such a sleeve can, for example, be made entirely or partially of corrugated cardboard, also known as E-wave. This has the advantage that corrugated cardboard can be made from renewable raw materials and can be completely recycled. Alternatively, e.g. solid cardboard can also be used. Other, in particular temperature-stable, materials are also conceivable.

In an embodiment of the slide sleeve according to the invention, which can be combined with any of the embodiments to be mentioned, if not in contradiction to this, the articulated connections allow the third ceiling part to be lowered below the highest point of the first side wall and / or below the highest Point of the second side wall in relation to the floor.

Such lowering of the third ceiling part is possible, for example, by folding the articulated connection between the first and the third ceiling part and the articulated connection between the second and the third ceiling part outwards, whereas all other articulated connections fold inwards. However, the term "folding" is not only to be understood in the classical sense (folding paper or fabric along a line and thus bringing it into a certain shape), but also includes any type of movement of the elements of the sliding sleeve (elements: ceiling, floor, first Side wall and second side wall) around the hinge axes.

In an embodiment of the slide sleeve according to the invention, which can be combined with any of the above-mentioned embodiments and with any of the embodiments yet to be mentioned, if not contrary to this, at least one of the free outer edges of the third ceiling part is at least one across the width of the third cover part projecting contact element, in particular an articulated side wing.

Such a contact element can e.g. are an articulated one-piece side wing, which extends over the entire length of a side edge of the third ceiling part. However, a plurality of narrow side wings can also be arranged in an articulated manner along the whole or part of the length of a side edge of the third ceiling part. In general, contact elements can be arranged on one or both outer edges of the third ceiling part. Instead of side wings, which e.g. Arranged on the third cover part via articulated connections which fold outwards, such a contact element can also be a rubber lip or the like, which can be connected to the third cover part not in an articulated but also in a rigid manner. Depending on the design of the contact element, this can e.g. Ensure a better fit between the sliding sleeve and the insert, for a seal between the cover of the sliding sleeve and the insert, for stabilizing the insert and / or for guiding when the sliding box is closed.

In one embodiment of the push-on sleeve according to the invention, which can be combined with any of the above-mentioned embodiments and with any of the embodiments yet to be mentioned, if not contrary to this, one or more of the articulated connections comprise: - a perforation; and / or - a fold; and / or - a crease line; and / or - a scratch line; and / or - an adhesive strip; and / or - a piece of fabric tape; and / or - a hinge; and / or - a ring bond.

In an embodiment of the slide sleeve according to the invention, which can be combined with any of the above-mentioned embodiments and with any of the embodiments yet to be mentioned, if not in contradiction to this, the third cover part has at least one projection, which is adjacent to the first cover part or is arranged to the second ceiling part. This at least one projection projects over the first hinge axis of the first ceiling part or over the second hinge axis of the second ceiling part.

If it folds outwards around the hinge axis of the hinge connection which connects the third cover part to the first or the second cover part, the projection remains as a kind of extension of the third cover part and projects like a mandrel or pin over the first or second joint axis out. Such a projection can be useful for snapping the push-on sleeve into a correspondingly complementary insert (for example provided with a recess).

In an embodiment of the slide sleeve according to the invention, which can be combined with any of the above-mentioned embodiments and with any of the embodiments yet to be mentioned, if not in contradiction to this, the third ceiling part has four projections. Of these, two opposite projections are adjacent to the first ceiling part and projecting over the first hinge axis of the first ceiling part and two opposite projections are adjacent to the second ceiling part and projecting over the second hinge axis of the second ceiling part.

A larger number of projections can be advantageous in order to achieve a more stable, but still soluble connection between the insert and the sliding sleeve.

In an embodiment of the slide sleeve according to the invention, which can be combined with any of the previously mentioned embodiments and with any of the embodiments yet to be mentioned, unless this is in contradiction to this, the base has at least one guide element leading into the sleeve.

Such a guide element or such guide elements facilitate the insertion of an insert into the sliding sleeve. Furthermore, the guide elements can ensure a more stable fit and center the insert in the slide-over sleeve. Guide elements can either be formed in one piece with the push-on sleeve, for example by folding a partial punch-out, or be formed by an external object fastened inside the push-on sleeve. E.g. wedge-shaped structures can be glued to the bottom of the sliding sleeve or attached in some other way adjacent to the side walls. The side of the wedge-shaped structures that is inclined toward the side walls is preferably designed to be complementary to the shape of the insert.

In an embodiment of the slide sleeve according to the invention, which can be combined with any of the above-mentioned embodiments and with any of the embodiments yet to be mentioned, if not in contradiction to this, the at least one guide element is formed by a die-cut from the bottom and with it articulated two-piece tab, the first tab part of which is also articulated to the second tab part.

This type of forming a guide element is particularly economical, since no additional materials for the guide element itself, for attaching the guide element etc. are consumed, but the guide element itself can be punched out and folded out of the existing slide sleeve. Due to the length of the first bracket part in relation to the length of the second bracket part, the inside angles of the triangle formed from the first bracket part, the second bracket part and a part of the bottom of the sliding sleeve can be varied. Accordingly, by positioning the tab and its dimensions, the guide element can be optimally adapted to the geometry of the insert.

In an embodiment of the slide sleeve according to the invention, which can be combined with any of the above-mentioned embodiments and with any of the embodiments yet to be mentioned, if not in contradiction to this, the length of the third ceiling part between the first ceiling part and the second ceiling part is smaller than the length of the bottom between the first side wall and the second side wall.

If the floor is shorter than the third ceiling part, it is possible that the sliding sleeve can assume a conical shape in cross section by lowering the third ceiling part, which tapers from the floor towards the ceiling.

In an embodiment of the slide sleeve according to the invention, which can be combined with any of the above-mentioned embodiments and with any of the embodiments yet to be mentioned, if not in contradiction to this, the first hinge axis of the first cover part and the second hinge axis of the second cover part are relative to one another parallel and / or the articulation axes of the articulated connections of the cuff are parallel to one another and / or the first articulation axis of the first cover part, the second articulation axis of the second cover part and the articulation axes of the articulated connections of the cuff are parallel to one another.

In an embodiment of the slide sleeve according to the invention, which can be combined with any of the above-mentioned embodiments and with any of the embodiments yet to be mentioned, if not contrary to this, the length of the ceiling is together with the length of the first side wall or second side wall identical to the length of the bottom together with the length of the second side wall or the first side wall.

If this requirement is met, the spanned sliding sleeve forms a rectangle in the side view. Furthermore, the sliding sleeve can be transferred from the open to a quasi-flat state in which the ceiling is displaced relative to the floor, either in the direction of the first side wall or in the direction of the second side wall. This relative movement and the associated lowering of the ceiling towards the floor are made possible by the articulated connections of the floor and ceiling to the side walls. The embodiment just described is particularly advantageous for the transport of the push-on sleeves, since they reach their destination in a space-saving manner and transport costs can be kept so low.

The object is further achieved by a sliding box comprising a sliding sleeve and an insert.

Such a sliding box can include, for example, one of the sliding sleeves described above. The insert can, for example, be made entirely or partially from corrugated cardboard, also known as E-wave.

Alternatively, e.g. solid cardboard can also be used. Other, in particular temperature-stable, materials are also conceivable. However, the temperature stability is of greater importance for the material or the material combination of which the insert is made, since this is the actual storage container for food and snacks to be heated, for example. The push-on sleeve, on the other hand, can be removed before heating, so that its material or the material combination should not, or at least only to a lesser degree, be temperature-resistant.

Basically, the sliding box is to be opened and closed as described below: First, the insert must be inserted into the interior of the clamped push-on sleeve and positioned essentially in the center. For closing, pressure or force is then exerted on the third cover part of the push-on sleeve from above, so that it is lowered and can partially penetrate into the insert to a depth at which the insert delimits an area that corresponds to the area and also to the area Dimensions of the third ceiling part essentially corresponds. To open the sliding box, either pressure or force is then exerted on the first and second side wall of the sliding sleeve, starting from the inside of the sliding sleeve, or pressure or force is exerted on the first cover part and the second cover part, namely in one third part of the ceiling opposite direction. The pressure or force application point should be in a region of the first and second ceiling part that does not protrude into the insert. The process of opening and closing can be repeated any number of times, practically up to the point of material fatigue.

In an embodiment of the sliding box according to the invention, which can be combined with any of the embodiments yet to be mentioned, if not in contradiction to this, the insert is a conical box. The conical box is open on the side opposite the tapered side. The dimension of this open side is larger than the dimension of the third ceiling part.

When merging the push-over sleeve and the insert, the tapered side of the insert points towards the bottom of the push-on sleeve and the open side of the insert points towards the ceiling of the push-on sleeve. The insert is then pushed into the interior of the push-on sleeve, for example guided by guide elements.

In an embodiment of the sliding box according to the invention, which can be combined with any of the above-mentioned embodiments and with any of the embodiments to be mentioned, if not in contradiction to this, the conical box has at least one recess on the inside at a height which is adjacent is to an edge extending from the tapered side to the opposite side.

Such a recess adjacent to the tapered side to the edge extending opposite this side can be arranged on any inner side of the conical box and can also extend over two adjacent inner sides. It is also possible, for example, to have four recesses at the same height, one for each edge. The recess or the recesses or at least part of the recesses can be continuous, that is to say formed through the entire material thickness and thus form a kind of through opening. Alternatively, the recess or the recesses or at least some of the recesses cannot be continuous and only affect the inside of the insert, so that no through opening is formed and the entire material thickness is not covered by the recess. A recess can not only be formed via a material recess, but also via two adjacent but not merging material thickenings. Such a thickening of the material can be, for example, a silicone ring, which is located at a corresponding location inside the insert, which e.g. is made of E-wave, is attached. The “material” part of the terms “material recess” and “material thickening” should not be understood here to mean that the material inevitably has to be the same.

In an embodiment of the sliding box according to the invention, which can be combined with any of the above-mentioned embodiments and with any of the embodiments yet to be mentioned, if not in contradiction to this, the dimension of the third ceiling part corresponds to the dimension of the conical box at height, on which the conical box has at least one recess.

In an embodiment of the sliding box according to the invention, which can be combined with any of the above-mentioned embodiments and with any of the embodiments yet to be mentioned, if not in contradiction to this, the sliding sleeve and / or the insert at least partially comprise corrugated cardboard and / or solid cardboard .

The manufacture of the sliding box from corrugated cardboard and / or solid cardboard enables a reduction in production costs, in particular in comparison to PET trays, which are currently often used as storage containers for food and snacks to be heated, for example.

In an embodiment of the sliding box according to the invention, which can be combined with any of the above-mentioned embodiments and with any of the embodiments yet to be mentioned, if not in contradiction to this, the push-on sleeve and / or the insert has at least one RFID chip.

The object is further achieved by a flat blank comprising four hingedly connected surface sections arranged in a row with fold lines. The surface sections and fold lines are arranged in such a way that the surface blank can be folded into a cuff and one of the surface sections is divided into a first section, a second section and a third section between the first and second sections. The third section is delimited by fold lines that fold outwards; the other fold lines are fold lines that fold inwards.

1 shows a flat blank 100 according to the invention with four surface sections 140, 110, 120, 130 arranged in a row and connected in an articulated manner. For example, a sliding sleeve according to the invention can be formed from such a flat blank 100. If the flat blank 100 is folded into a sleeve, one of the surface sections forms the ceiling (e.g. section 110), bottom (e.g. section 130), first side wall (e.g. section 120) and second side wall (e.g. section 140) of the sleeve. For this purpose, the fold lines 152, which are arranged between the sections 130/120, 120/110, and 110/140, are folded inwards. The two ends of the row of surface sections, that is to say the end edge of section 130 and the end edge of section 140, are brought together to close the cuff (indicated by the arrows pointing at one another) and are connected to one another in an articulated manner. This can be done, for example, via a ring binding, a hinge or by means of a strip of adhesive or

Fabric tape happen. The section which is provided to form the cover 10 of the sleeve, in this example section 110, is in a first section 111, a second section 112 and in a third section 113 lying between the first section 111 and the second section 112 divided. The third section 113 is delimited by fold lines 151 which fold outwards. Accordingly, the first cover part 111 and the third cover part 113 and the second cover part 112 and the third cover part 113 can be folded into a valley. Adjacent sections between which there are fold lines 152 that fold inward are folded into a mountain.

2 shows an embodiment of a flat blank 100 according to the invention with five surface sections arranged in a row and connected in an articulated manner. For example, a sliding sleeve according to the invention can be formed from such a flat blank 100. In contrast to the flat blank 100 shown in FIG. 1, the section 140 which later forms the second side wall in the sleeve is composed of two sections 140 ', 140 ". The sections 110, 120, 130, 140' and 140" are used to form the sleeve. Folded inward along the fold lines 152 and to close the cuff, the partially overlapping sections 140 ', 140 "are connected to one another in the overlap area 144, for example by gluing, riveting or stapling. Such an overlap area 144 or connecting area can basically be found anywhere on the cuff located, i.e. on the ceiling, floor, first side wall or second side wall - The section forming the part corresponding to this part (ceiling, floor, ...) of the machnette is then formed in two parts, one part of which is at one end and the other part at the other end of the are arranged in a row. The division of the section 130 which later forms the ceiling is equivalent to that shown in FIG. 1.

3 shows a further embodiment of a flat blank 100 according to the invention, for example for forming a slide-over sleeve according to the invention. 3 corresponds to that of FIG. 2 (section 140 is composed of two sections 140 ', 140 ", overlap area 144, arrangement of fold lines 151 and 152, ...). In contrast to this However, the sections of this flat blank WO are not all rectangular, nor are all sections of the same width and / or a constant width. Also shown in Fig. 3 is a coordinate system which indicates which dimension of the blank 100 is the width b and which is the length I. The same coordinate system can also be applied, for example, to FIGS. 1 2 and 4. Section 140 "is, for example, trapezoidal with the shorter base side at the end of the row of sections and the longer base side adjacent to section 110. Section 140 ', however, with which the section 140 "together in the cuff will form the second side wall is rectangular. The later the bottom of the M Section 130 forming cuff has essentially a rectangular basic shape, which however has two different widths, that is to say is wider in the central region than at the ends adjacent to sections 120 and 140 '. The section 120 forming the first side wall is likewise trapezoidal with the shorter base side adjoining the section 130 and with the longer base side adjoining the section 110. The section 110 forming the ceiling is divided into a first section 111, a second section 112 and FIG a third section 113 lying between the first section 111 and the second section 112. The first and the second section 111, 112 are rectangular, but have a somewhat smaller width than the third section 113. This is essentially rectangular, but differs from a classic rectangle through the projections 70 (for the sake of clarity, only one of the two projections is provided with a reference symbol) on the side facing the second subsection 112. The projections 70 protrude beyond the second hinge axis 132 of the hinge connection between the second and third partial sections 112, 113 and, in the embodiment shown, have a width which corresponds to the difference between the width of the second section 112 and the width of the third section 113. The projections shown have a rectangular shape, the length and width of which are similar in size. On the other hand, on the side of the third section 113 adjoining the first section 111 there are no projections projecting beyond the first joint axis 131. A contact element 60 is arranged on each of the two free outer edges of the third partial section 113. In this embodiment, the contact elements 60 are articulated side wings, the articulated connection of which can be formed, for example, by an outwardly creasing line or scoring line.

4 shows yet another embodiment of a planar blank 100 according to the invention, for example for forming a push-on sleeve according to the invention. In contrast to the embodiment shown in FIG. 4, this has four projections 70. Two of the projections 70 ″ are adjacent to the second section 112, lie opposite one another and project over the second hinge axis 132. Two of the projections 70 ′ are adjacent to the first section 111 , lie opposite each other and protrude beyond the first hinge axis 131. Section 130 has two tabs 90, which can each be used to form a guide element, tabs 90 are punched out of section 130 except for one edge, and an edge with the latter via this Section 130 is hingedly connected, the tabs 90 are in two parts, the first tab part 91 of a tab 90 is hinged to the second tab part 92. The second tab part 92 has a tongue 93 which, after the tab 90 has been folded into a triangle, can be used for this purpose to fix the fold by the tongue 93 through an opening 94 at the transition of the section 130 to the section adjacent to it is inserted. However, the planar blank can have further openings, such as in section 113. If this later becomes, for example, the third cover part of a sliding sleeve, this opening 94 allows a view from above into the inside of the sliding sleeve. Such an opening can, for example, also be covered subsequently with a transparent film in order to cover the inside of the sliding sleeve, e.g. to protect the slot itself or the contents of the slot and still allow a clear view of it. Furthermore, in this embodiment of a flat section 100 according to the invention, an RFID chip 99 is applied to the partial section 113. This can, for example, contain data about the flat cut (material, date of manufacture, delivery address ...) or be used to store information about the content of a sliding box, of which the flat cut is a component.

5 shows a push-on sleeve 1 according to the invention, which is formed from a flat blank 100 according to the invention. The figure shows schematically which sections and fold lines or articulated connections can be found where in the push-on sleeve. The flat blank 100 shown here is based on the embodiment from FIG. 3.

Fig. 6 shows a sliding box 200 according to the invention consisting of a sliding sleeve 1 according to the invention and an insert 2. The sliding sleeve 1 has two guide elements 80, which have a triangular basic shape and are glued to the bottom 30 of the sliding sleeve 1. Furthermore, the ceiling 10, which is divided into a first ceiling part 11, a second ceiling part 12 and a third ceiling part 13, the first side wall 20 and the second side wall 40, which in this case is composed of two sections, can also be seen is a contact element 60 projecting over the width of the third ceiling part 13.

In the center of FIG. 7 is a top view of an insert 2, which together with a push-on sleeve according to the invention can form a sliding box according to the invention. Four side views, which show the exterior of the insert 2, are grouped around the top view, which allows an insight into the interior of the insert. The slot 2 shown here is a conical box open at the top. This has four recesses 75 (for the sake of clarity, only one of the four is provided with the reference number). The recesses 75 are measured from the bottom of the box at the height h, which is drawn in with the aid of a double arrow and is drawn on the inside of the box by means of a dashed line between two recesses 75. Furthermore, a section line a-a is drawn through the insert 2, which gives orientation about where the cross section shown in FIG. 8 is located.

8 shows an enlarged section of a cross section along the section line a-a drawn in FIG. 7. The position of the section can be seen in FIG. 6, in which it is indicated by a rectangle. The first side wall 20, the third cover part 13, the first hinge axis 131 and the projection 70 projecting beyond the first hinge axis can be seen from the sliding sleeve 1. For better understanding, the first cover part 11 is shown (dashed), even if it is deeper in the The plane lies as the other elements of the sliding sleeve 1 shown. From the insert 2, which corresponds to the conical box shown in FIG. 7, part of the side wall with recess 75 can be seen. In particular, the interaction of the projection 70 of the sliding sleeve 1 and the recess 75 of the insert 2 can be clearly seen. Projection 70 and recess 75 allow the cover of the slide-over sleeve 1 to snap into the insert 2 and thus ensure stabilization of the sliding box and a better hold of the slide-over sleeve 1 and insert 2. In the embodiment shown here, the recess is not continuous. It therefore does not break through the entire material thickness of the insert 2.

FIG. 9 shows a perspective illustration of a section of a further embodiment of a sliding box 200 according to the invention. The position of this section shown in perspective is comparable to the position of the section shown in FIG. 8. On the one hand, the first side wall 20, the first cover part 11, the contact element 60 and the projection 75 of a slide-over sleeve 1 can be seen. On the other hand, a part of an insert 2, which comprises a recess 75, is shown. The recess shown here is a continuous recess that penetrates the entire material thickness of the side wall of the insert 2.

10 shows an embodiment of a slide-in unit 2 as can be used in a sliding box according to the invention. The insert 2 shown here has a total of four recesses 75 and can, for example, be folded from a flat blank and held in shape by adhering two tabs to one or the other section provided with two recesses 75. In the embodiment shown, the recesses 75 penetrate the entire material thickness of the one section, but there is still no complete breakthrough in the finished insert, since the glued tabs cover the recesses from the outside of the insert.

11 shows a vertical section through an embodiment of a sliding box 200 according to the invention comprising a sliding sleeve 1 and an insert 2. The sliding box shown here is in the open state, that is to say the third cover part 13 of the sliding sleeve 1 does not protrude into the Insert 2. First ceiling part 11 and first side wall 20, first side wall 20 and floor 30, floor 30 and second side wall 40, and second side wall 40 and second ceiling part 12 each form a 90 ° angle. The first and second side walls 20, 40 are each 72.5 mm high or long when transferred to the corresponding flat blank. The floor 30 and the ceiling, consisting of the first ceiling part 11, the second ceiling part 12 and the third ceiling part 13, each have a length of 270 mm. The total length composed of the length of the ceiling and one of the side walls 20; 40 corresponds to the total length composed of the length of the bottom and the other side wall 40; 20. The ceiling is composed of 23.5 mm of the first and second ceiling parts 11, 12 and 223 mm. of the third ceiling part 13. The insert 2, shown here as a conical box, has an underside (lying on the bottom 30 of the sliding sleeve 1) with a length of 201 mm and an upper side (pointing towards the ceiling of the sliding sleeve 1) of 233 mm . The insert 2 further comprises two side walls, each with a height of 72.5 mm, one adjacent to the first side wall 20 of the sliding sleeve 1 and one adjacent to the second side wall 40 of the sliding sleeve 1. However, the height of the sliding walls does not correspond to their length, since they do not run at a right angle, but form the outside of the insert 2 an outer angle of 75.4 °. Further dimensions can be found directly in the drawing. The sliding box 200 shown in FIG. 11 is one embodiment of many of a sliding box according to the invention. For example, all the size specifications described and shown in the figure can be enlarged or reduced by a factor, that is to say the entire dimensioning can be changed while maintaining the size ratios. It is also e.g. possible that the length of the first ceiling part 11 is not identical to the length of the second ceiling part 12. However, as a result, the symmetry of the side walls of the insert 2 and the outside angle which they form with the lower part would then also have to be eliminated.

12 also shows a vertical section through an embodiment of a sliding box 200 according to the invention. However, the sliding box shown here is in the closed state, that is to say the third cover part 13 of the sliding sleeve 1 projects into the insert 2. Such a sliding box 200 can be closed, for example, by exerting pressure on the third cover part 13 from above. The length dimensions have not changed compared to FIG. 11, but some angles have changed. E.g. the bottom 30 and the first side wall 20 and the bottom 30 and the second side wall 40 no longer form a 90 ° angle, but a 75.6 ° angle, i.e. the side walls 20, 40 incline towards the inside of the sliding sleeve. The side walls 20, 40 no longer enclose a 90 ° angle with the first or the second ceiling part 11, 12, but instead form an acute angle. The third ceiling part 13, on the other hand, is still parallel to the floor 30, but compared to FIG. 11 it is lowered by 22.8 mm and projects 10 mm deep into the insert 2. This 10 mm can be used as storage space e.g. for cutlery, napkin and / or spices.
