    Food packaging
    Field of the invention
    The invention relates to a food package comprising a plurality of food products that contain granules that can become separated from the food product. The food packaging comprises a packaging box which extends around the plurality of food products and contains a body and a lid, which body is provided with a bottom and a first and second mutually opposite side walls, the bottom being connected to the first and the second side walls along edges of the packaging box formed on folding lines, thereby defining an interior space in the body for the food products. The interior space is exposed at the top so that food products can be introduced and removed. The lid covers at least the exposed inner space of the body
    BACKGROUND OF THE INVENTION
    For example, food products that contain grains that can be separated are sugar cubes and cookies. These products are usually packaged in packaging boxes and contain granular elements that can become detached from the product during transport or storage.
    Sugar cubes form a well-known product. Sugar cubes are usually made from refined or semi-refined crystalline sugar, which is produced from raw sugar in a multitude of purification steps which are known per se to a person skilled in the art. The granular sugar is reformed into lumps by mixing it with a binder such as water or protein, after which the sugar is brought into the desired shape, it being generally known that the desired shape does not have to be square, despite the English name " sugar cube ”.
    After their formation, the sugar cubes are packaged in packaging boxes. This packaging process is carried out appropriately when the sugar cubes are still warm, in order to optimize the process and to reduce the risk of contamination. It is common for one filled packaging box to have a total weight of approximately 1 kg, although larger or smaller packaging boxes are certainly also possible.
    Individual sugar granules (i.e., crystals) can easily come loose and typically have a small size that allows them to disappear from the package. This applies in particular to packaging boxes in which no or hardly any glue is used. It is preferred in food production that the use of glue is avoided so as to prevent unintended contamination of the food product with the glue. Furthermore, the use of plastic bags around the food products is undesirable, both for environmental reasons and also because it tends to reduce packaging density. The advantages of packaging boxes are the high density and the good stackability. The consequence is, however, that there is a risk that granules that have become detached from the food product will disappear from the packaging box. This loss of sugar crystals can not only be regarded by customers as impractical and insufficiently clean, but it can also attract animals during storage of the packages containing the food products, for example in warehouses.
    Summary of the invention
    It is thus an object of the invention to provide an improved food package of the type mentioned in the opening paragraph, which is less vulnerable to loss of grains to an outside of the package
    According to a first aspect of the invention this object has been achieved in a food package comprising a plurality of food products that contain granules that can become detached from the food product during storage and / or transport, and a packaging box that is located around the plurality of food products and a body comprises a bottom and a first and a second mutually opposite side walls, which bottom is connected to the first and second side walls along edges of the packaging box, thereby defining an inner space in the body for the food products, which inner space of the body is exposed to a top for inserting and removing food products. The packaging box is furthermore provided with a lid, which comprises at least one wall which covers said exposed inner space. The body is further provided with at least one strip that extends above the said inner space, which strip is connected to a corresponding one of the first and second side walls along an edge of the body, the strip touching the wall of the lid over at least a portion of the strip and at least substantially. US 4,738,365 discloses a container for storing a product and keeping it in place while the product is heated in a microwave or conventional oven. The container comprises a box portion that resembles a tray and that is attached and secured within a leakproof lid. One side of the box-shaped box has an access flap suitable for tearing-up, and which can be re-closed after tearing-open and held in place by an intermediate fit between two shoulders spaced apart and are defined along a fold line, with which the access flap is connected to the reclosing tab. GB 1912 20040 discloses a package for holding a certain number of sugar lumps. The package is made from a sheet with a bottom, sides and ends formed by flaps covering the top of the valves. Both upper flaps have a width that is equal to that of the package, the outer one being secured with a tongue and hole connection. DE-U 9413813 discloses a one-piece cardboard mold which is suitable for forming a box for the aroma-tight packaging of tea bags. DE-A-1586454 discloses a cardboard construction consisting of a body and a lid. US-A-3572576 discloses a frozen food carton formed from a single sheet and comprising a horizontally laid bottom panel; vertically erected and cooperating front and side panels rotatably connected to the bottom panel to form a rectangular box-shaped part intended as a vessel to contain a commidity; a narrow flap rotatably connected to the free upper edge of each of the front and side panels, each of said flaps having a vertical view of a dimension considerably smaller than the vertical direction of each of said front, rear and side panels, a rectangular and impermeable cover panel rotatably connected to a free top edge of the rear panel and provided with outer corners defined by three intersecting free edges and further having a length and width that is substantially equal to fit the corresponding length and width of the bottom panel, which cover panel extends above the narrow flaps and is adhesively bonded to the narrow flaps only to form a tightly enveloping cardboard seal. GB-A-1256801 discloses a method for making a cardboard from a single blank sheet of sheet material by folding it and joining the sides of the sheet to form a tube with open ends that have a front, bottom, back and comprises a top of the cardboard, after which the ends of the cardboard are closed with further parts of the sheet. These further parts are present in the tube and the closure is formed in that an edge part of the sheet is engaged by two other parts of the sheet, so that the cardboard can be opened by pulling said edge part away from the other two parts and the entire to raise the top as part of a lid that is rotatably connected to the rest of the cardboard.
    It has been observed by the inventors in studies that have led to the present invention that the leakage of granules can be considerably reduced by applying strips that touch the lid wall. The touch configuration provides this improvement without glue being applied between the strips and the lid wall, and thus constitutes an acceptable option in the field of packaging sugar cubes, cookies and the like.
    More in particular, the strip is shaped such that it is elastically rotatable along said edge of the body. The strip will thus assume a "free" orientation in the absence of the cover wall. In such a free orientation, the strip makes an angle with a plane parallel to the bottom wall of 10 to 50 degrees, preferably 15 to 45 degrees, for example 20 to 45 degrees and more preferably 25 or 30 to 40 degrees. Nevertheless, after assembly, the cover wall is - at least substantially - in contact with the strip, or a portion thereof. The lid then provides a counter force against the strip, so that the strip is turned downwards. The strip works like a spring. The elasticity is thereby determined by the choice of material of the body, and during the formation of the edge along which the rotation takes place. When the lid is removed, the strip will return to its initial state, i.e., the initial "free" orientation, in accordance with its spring action. In addition, the strip will generally - and depending on the choice of material of the body and the formation of the edge - turn back by at least one third of the angle it initially took before the cover was brought into contact with the strip during assembly. Preferably the strip will roll back by at least half the degree of the angle it initially took, and more preferably by at least two-thirds or even by three-quarters of the angle that it initially took.
    In a preferred embodiment, the edge of the body is shaped as a cut line. More specifically, the edge of the body is incised from the outside of the body so that the body can be bent inwards. The term "incised" is used herein in its usual sense in that there is a notch for the purpose of providing a line along which folding can take place; this notch did not cause significant damage to the surface structure unless specifically stated otherwise. It is preferable that the edge of the body forms a cut line that is cut uninterrupted along the entire length of the "edge of the body", provided that that edge acts as a rotation axis. However, it is not excluded that the incised line is limited to parts thereof, and / or combined with local incisions or cuts that break the surface structure.
    In a preferred embodiment, the strip extends over the entire length of a side wall. A plurality of short strips can also be used instead of a single strip. Alternatively, the strip may be limited to a specific portion that is most susceptible to leakage.
    Examples of materials from which the body can be made are cardboard, both single-layer and multi-layer, synthetic polymeric materials such as polyethylene (usually LDPE or HDPE), and polypropylene, and multi-layers thereof. Preferably the body is made of cardboard containing a plurality of layers; in a preferred embodiment, the incised line is designed such that a first of the said layers is broken into the cardboard. This has proven to be an effective way to achieve the intended elasticity. More preferably, the cardboard has an asymmetrical layer stack, the inner and outer layers of the cardboard being different. The incised line is thus able to reduce the rigidity of the cardboard to a level required for the intended elasticity. In yet a further embodiment, the cardboard comprises a layer that is impermeable to water, in order to reduce the diffusion of moisture through the food package. Such coatings are generally applied as an outer layer (i.e. on the outside or on the inside of the cardboard) and are known per se. Alternatively or in combination therewith the cover may be provided with such a water-impermeable layer. The term "water impermeable" is used herein to indicate a material that greatly limits the flow of moisture (water) through the package.
    In a preferred embodiment, strips are present on two side walls of the body, and more preferably on three side walls. In a further preferred embodiment, strips are present on all side walls of the body, i.e. each of them is connected to a corresponding side wall along an edge of the body. This edge of the body can be designed as an incised line. If the first and the second side wall do not have the same size, it may be appropriate that the depth of the notch and / or the pattern of the notch (along the entire length or only along certain parts) differs for the first and the second side wall. For the sake of completeness, it should be added that only a portion of the strips will touch the cover wall, for example in view of the upward free orientation of the strips. Furthermore, it is not excluded that a small gap remains between the strip and the cover wall, for example in the order of micrometers, or that local gaps would exist.
    It is most preferred that in such a situation, the side edges of the strips extend obliquely. More formally, it involves the side edges between the edge of the body and a primary edge that extends substantially parallel to the edge of the body. It is advantageous if the said side edge and the edge of the body enclose an angle that is smaller than 45 degrees. This prevents the corners of neighboring strips from overlapping each other. Such an overlap is undesirable, since it would impede the elasticity of the strips, which increases the risk of leakage.
    In yet a further embodiment, an access opening is provided in the strip, so as to facilitate access to the food product by a user. Such an access opening is most convenient in combination with the preferred embodiment of the lid according to the invention, which is provided with an opening panel extending on the lid wall and a side wall on the front side of the lid. Nevertheless, an access opening can also be used in combination with other covers. In fact, it is an advantage of the invention that covers of different nature can be used without considerably increasing the risk of leakage. The possibility of variation of the lid relates to both the design of the lid and the material of the lid.
    Examples of materials for the lid include cardboard, both single-layer and multi-layer, synthetic polymeric materials such as polyethylene (typically LDPE or HDPE) and polypropylene, as well as multi-layer versions. The cover is preferably made of the same material as the body.
    Examples of designs of the lid are a lid with a lid wall and a first and a second mutually opposite side walls; a lid based on a lid wall, a bottom wall and a first pair of side walls, preferably connected to each other, which can be wrapped around the body. Such a design of the cover need not have a second pair of side walls, although such side walls may be present as flaps that can be folded and preferably secured to the body after wrapping. Other designs known to those skilled in the art and variations on said designs may be used otherwise. The advantage of using a separate cover can be that when the cover is printed with an image, the body does not have to be printed. Nevertheless, in a further embodiment, the cover wall - with any side strips present - is part of the body, i.e. cover and body are made of a single piece of material.
    In a preferred embodiment, the lid wall and at least the side walls extending along the long sides of the lid wall (i.e., the first side walls) are made from a single sheet of material. Preferably, those longer edges are defined as folding lines. In such a design, the advantage of an upwardly curved shape of the lid wall lies, among other things, in that the angle along the fold line is slightly greater than 90 °. This larger angle is also due to temperature variations during the packaging process. It happens in particular when the sugar cubes are packed in the packaging box when they are still warm. The initial expansion of the paper box due to the heat dissipation of the hot sugar cubes can lead to some tolerance during the cooling process.
    The cover is preferably provided with an opening panel which extends on the top side (i.e. as part of the cover wall) and more preferably also extends on a first side wall. An image on the lid may indicate that the first side wall is the front of the food package.
    Even though the food package according to the invention is very suitable as a package of sugar cubes, it can also be used for other food products that contain granules that can loosen during storage or transport. More in particular, the package for sugar cubes is intended for sugar cubes which are provided with a groove, such that a single sugar cube can easily be divided by a user. This type of sugar cubes is sold by the applicant under the brand names Harde Klontjes® and Morceaux Durs®. However, the current food packaging can also be used advantageously for cookies and biscuits that are conventionally packaged with an insert and often with a hermetically sealed layer of a synthetic polymer. The closure achieved in the invention makes it possible to package products in high density and without risk of leakage, which is desirable for such food products. The packaging has the further advantage that it is preferably made from recyclable materials, which is advantageous for environmental reasons.

    Description in detail of the illustrated embodiment
    The figures are not drawn to scale and are schematic in design. The same reference numerals in different figures refer to the same or corresponding elements. The food products are not shown in the food package for the sake of clarity.
    FIG. 6 shows an embodiment of the food packaging, more particularly the packaging box thereof. The packaging box is constructed from two primary elements, the body and the lid. A flat shape ("blank") of the body 10 is shown in FIG. 1. A blank of the lid 60 is shown in Figure 2. As shown in FIG. 6, the packaging box is often block-shaped with a lid wall containing an opening panel 68 on an upper side which further extends on a front side with a front side part 65. Upon opening, portions 69 of the lid wall (61, see Figure 2) remain closed. The opened opening panel 68 exposes an inner space of the packaging box, and also of the body (10, see Fig. 1). The inner space is determined by means of the bottom wall 11 and first side walls 12 (see Fig. 1) and second side walls 66. Glue can be present between the first side walls 12, 62 and between the second side walls 16, 66, so as to to secure the cover. FIG. 6 also shows a strip 22 which is provided with an access opening 29.
    It has been found that a commercially available food package without a strip 22 caused leakage of sugar granules, particularly when transported over large distances and / or storage in warehouses for a longer period of time. This leakage is prevented by the present invention. It is of course desirable that the costs remain low. For marketing reasons, it is advantageous if the packaging box does not have to be fundamentally altered on points other than necessary for the introduction of the invention; and it is an advantage of the invention that this object can indeed be achieved. To avoid contamination, any additional application of glue is considered risky and preferably avoided. One solution could have been to seal the packaging box or a plurality of packaging boxes with an additional sealing layer, such as, for example, made from polyethylene. However, this is undesirable for cost reasons and for environmental reasons.
    According to the invention, the body 10 is provided with strips 21, 22, as shown in FIG. 4 and 5. The strips 22 are connected to the first side walls 12 along body edges 23. The strips 21 are connected to the second side walls 16 along body edges 24. In the preferred embodiment shown in Figures 4 and 5, the strips 21, 22 are present on all sides, ie along the four body edges 23, 24; however, this is not always necessary. Moreover, the strips 21, 22 are present along the entire length of the body edges 23, 24. This is preferred, but need not be necessary, depending on the situation and the requirements. In view of the structure of the lid and the body, it appears that the second side walls 16 form the main leak path. Therefore, it is preferred that the strips extend in particular along the body edges 24 on the second side walls 16, and more preferably also along the body edges 23 in areas near the corners of the packaging box.
    More particularly, in the invention it holds that the strips touch the cover wall 61 in a closed state of the packaging box. In other words, in at least a portion thereof, the strips 21, 22 are substantially in contact with the cover wall 61, without being attached to the cover wall 61. This is achieved, in one embodiment of the invention, in that the strips 21, 22 are oriented upwards (upwards), in the sense that the primary edge 25 of the strip 21, 22 is higher than the body edge 23.24. This is shown in Figure 4 and in particular in Figure 5. This higher position occurs most strongly in the "free state", i.e. when the packaging box is open. When the body and lid are combined in a closed package box, the lid wall 61 pushes back from the lid 60, i.e. exerts a downward force on the strips 21, 22. This pushing back is made possible by the strips 21, 22 being able to rotate along the body edges 23, 24.
    In an important implementation of the invention, the rotation along the body edges 23, 24 is set as elastic. It is considered that such an elastic adjustment is very suitable for ensuring close contact between the strips 21, 22 and the cover wall 61, in order to minimize leakage. Moreover, this adjustment is favorable in connection with a cover 60 which is relatively flexible, for example in the case that the cover 60 is thin. When a relatively thin lid is used, the lid 60 may have a slightly convex shape. As a result, the precise location, in the vertical direction, of a small area of the cover wall 61 of the cover 60 may vary to some extent. By designing the strip as elastically rotatable along the body edges 23, 24, the strip (and in particular the portion near the primary edge 25) will touch the lid wall 61, even in situations where the vertical position of the lid wall 61 varies slightly. Moreover, when pressing down the lid wall 61, for example when a plurality of packaging boxes are stacked on top of each other, the strip 21, 22 can adjust its orientation.
    In one embodiment the elastic rotation along the body edges 23, 24 is worked out in that these body edges 23, 24 are designed as incised lines. The incised line reduces the thickness of the body, and thus provides a predetermined rotation line. The spring constant for the rotation can thus be selected in line with the requirements. This allows the strip to get an upward orientation in its free state.
    The strip 21, 22 is further preferably designed to allow an elastic rotation around the body edge 23, 24, and to allow elastic deformation of the cover wall 61 and / or the strip 21, 22 relative to each other. The elastic rotation is a form of bending at the height of a connecting piece (i.e. a body edge and / or an area around it) that is preferably completely elastic. Alternatively, the bending can be elastic within a certain range of angles. The spring constant is preferably large enough to withstand gravity, and to provide a counter force against the cover wall 61 of the cover 60. The elastic deformation of the lid wall 61 and / or the strip 21, 22 is suitably carried out in that the lid wall 61 of the lid is less rigid (more flexible) than the strip 21, 22 and preferably less rigid than the connecting piece (e.g. the incised line at the body edge 23, 24). This preferred embodiment allows the cover wall 61 to take on a shape corresponding to shape (conforming) to the strip 21, 22 at a microscopic level.
    FIG. 1 shows a blank of the body 10 provided with a bottom wall 11 as a central portion, and first side walls 12 and second side walls 16. The first side walls 12 are connected to the bottom wall 11 along edges 13, which form fold lines. The second side walls 16 are connected to the bottom wall 11 along edges 14, which also form fold lines. The edges 13, 14 are preferably incised to facilitate folding, as is known to those skilled in the art. The edges 14 extend along the first side walls 12. They form connecting edges between the first side walls 12 and side flaps 17. After folding, the side flaps 17 can be inserted through cut lines 161 so as to obtain a mechanical connection. The corners 162 of an inner portion of the second side walls can in turn be inserted through further cutting lines 171, so as to strengthen and flatten the mechanical connection.
    FIG. 1 further shows the presence of the strips 21, 22 which are connected to the first and the second side walls 16, 12 along body edges 23, 24. The outer edge of the blank is defined by an edge 25 of the strip 21, 22. Side edges 26 27 run between the body edges 23, 24 and the edge 25 of the strip, the latter suitably extending (as shown in this example of Fig. 1) substantially parallel to the body edges 23, 24 and enclosing corners and / or corners . The angles cq and a2 of the side edges 26, 27 on the strips 22, 21 relative to the first and the second side walls 12, 16 can be mutually the same or different. It is favorable when the sum of the angles and / or is less than 90 degrees. Preferably, each of the angles or a2 is smaller than 45 degrees. However, if the width (ie the perpendicular distance between the body edges 23, 24 and the edge 25 of the strip 25) of the strips 21, 22 is different from each other, it may be appropriate if one angle is greater than 45 degrees and the other smaller. It is considered appropriate that the angles of the side edges on a single strip are substantially the same in size (although opposite in orientation). Alternatively, the angles on each left edge can be substantially the same. and the angles on each right hand are substantially the same. Further variations are not excluded and may depend on the precise design of the packaging box.
    The width of the strips 21, 22 is preferably selected from 0.3 to 1.0 cm, for example 0.4 to 0.8 cm. The precise width of course depends on the size of the packaging box. The width is preferably chosen so that the strip 21, 22 touches the lid wall 61 within a two-dimensional contact area (instead of only along a single line). The width is also important for the mechanical behavior of the strip. More in particular, it is understood that the desired width depends on the rigidity of the material of the cover wall, on tolerance in the manufacturing process, the distance in the vertical direction between the edge of the cover wall 61 and the edge of the strips 21, 22 (where it is attached to the side walls 16, 12), and the size of the packaging box. More specifically, when the lid wall 61 forms part of a lid 60 or a lid portion extending between first side walls 62, the width is preferably between 4 and 10% of the width of the lid wall 61 between the opposite side walls 62. As is clear When taken from the blank, the first side walls 12 have a length that is at least twice as long as that of the second side walls 16. However, this ratio can be changed and also depends on the size of the package.
    FIG. 2 shows the blank of the lid 60 used in this preferred embodiment. However, it is not excluded that another cover is used. A cover wall 61 is placed as a central piece. First and second side walls 62, 66 are connected to the cover wall 61 along edges 63, 64, which are designed as folding lines. The fold line 64 extends to the first side wall 62 and is used as a fold line with the side flaps 67. An opening panel is defined, in particular in the cover wall 61, with a front portion 65 located on one of the first side walls 12. A removal strip 75 is defined to facilitate opening of the opening panel 68. The opening panel 68 and the removal strip 75 are detained on the basis of partially cut lines 73A, 73B, 74A, 74B. The partially cut lines 73A-74B preferably have a pointed pattern (eng: dotted), a dash pattern (eng: dashed, ie with cut sections alternated with non-cut sections) or a combination of dashes and dots (eng: dashed dotted). The cut portions may extend all the way through or partially through the material of the lid 60. Advantageously, the partially cut line 73A on the lid wall 61 has a different pattern than the partially cut lines 73B, 74A, 74B on the first side walls. Reasons can be the prevention of inflow of moisture into the packaging box and ease of use. The partially cut line 73A is in particular less open (more closed), in view of the fact that there is no underlying further packaging layer.
    FIG. 3 shows the packaging box in bird's eye view from below. The bottom wall 11 is shown transparent for the illustration. This figure shows how the strips 21, 22 touch the cover wall 61. This contacting preferably takes place over a two-dimensional contact area, wherein the cover wall 61 and the strip 21 are mutually aligned, and as a result no intermediate gap remains.
    FIG. 4 and 5 further show the body of different angles of view. They make it clear that the strip 21, 22 is directed upwards, at least slightly, so as to bridge a gap with the cover 60 and to ensure a two-dimensional contact area. Glue can be applied to the side walls 12, 16 so as to attach the cover 60 to the body 10. Such an adhesive can be defined as an adhesive line on the rear of the lid and can be thermally activated. The thermal activation can be provided by the heat dissipating from the food products, ie the sugar cubes in the inner space defined by the body 10. However, other ways of attaching the cover 60 to the body 10 are not excluded.
    FIG. 7 schematically shows a further embodiment of the packaging box according to the invention in bird's eye view. The box is shown in a state prior to filling with sugar cubes and for the final bending of the lid wall 62 and related pieces 62, 66 to close the packaging box. In this embodiment, the cover wall 61 is integral with the body, in the sense that the cover wall 61 is connected to a side wall 12 of the body 10. The cover wall 61 and the other elements of the body (in particular the bottom wall 11, the side walls 12, 16 and the strips 21, 22) are thus made from a single piece of material.
    As shown in this embodiment, the lid wall is connected to the side wall 12 which extends on the long side of the bottom wall 11. This side wall is particularly defined as the rear of the packaging box. However, it is not excluded that this side wall 12 forms the front of the packaging box, and that an opening panel is present which extends both on the cover wall 61 and on the side wall to which the cover wall 61 is attached.
    As further shown in this Figure 7, the cover wall 61 is connected to side walls 62, 66. These side walls are designed to be aligned with the side walls 12, 16. Preferably, the side walls 12, 62 and 16, 66 are glued or glued to otherwise attached.
    Instead of the cover wall 61 being connected to the side wall 12 and being part of the body, the cover wall 61 could be connected to a further side wall 62, which extends parallel to the (rear) side wall 12 and is assembled therewith, e.g. using glue. Such a design minimizes paper usage by omitting the flaps 67 (as shown in Figure 2). This omission of the flaps 67 is made possible by the strips 21, 22, which protect the edges of the packaging box against leakage. In addition, since the flaps 67 are omitted, the box becomes thinner on the sides, and any grooves between the flaps 67, the side wall 66 and the side wall 16 are minimized.
    Tests were carried out with the improved packaging box containing sugar cubes, which were supplied by the applicant under the brand name Hard Klontjes® / Morceaux Durs®. These sugar cubes contain a groove that facilitates division of the sugar cube by a user. Use was made of packaging boxes according to the invention and known packaging boxes that are currently being used by the applicant. Sugar cubes were placed in the packaging boxes immediately after their formation in an amount of 1 kg. The embodiment of the packaging box according to FIG. 1 and 2 was used. The packaging box according to the prior art had an almost identical design, except that there were no strips. The packaging box was sealed with glue on the first and second side walls. After storage, the packaging boxes were rotated 360 times several times, so that the lid went through a downward position during each rotation. The amount of leaked sugar granules from the packaging box according to the invention was near zero, and in this test was at least 80% and in particular more than 90% smaller than the amount of sugar granules that leaked from the packaging box according to the prior art.
    Thus, in summary, the invention provides a food package for a plurality of food products that contain granules, such as sugar cubes. The food packaging comprises a packaging box which is arranged around the food products and comprises a body 10. The body 10 is provided with a bottom wall 11 and first and second mutually opposite side walls 12, 16, thereby defining an inner space in the body for the food products. The inner space of the body 10 is exposed at the top for the insertion and removal of the food products. The packaging box further comprises a lid 60 with a lid wall 61; cover wall 61 covers that exposed inner space of the body 10. The body is provided with at least one strip 21, 22 extending above said inner space, which strip is connected to a corresponding side wall of the first and second side walls 12, 16 along an edge 23, 24 of the body, with the strip 21, 22 touching the cover wall 61, in at least a portion of the strip 21, 22 and at least substantially. The strip 21, 22 is preferably embodied such that a two-dimensional contact surface exists between the cover wall 61 and the strips 21, 22. The strip is preferably directed upwards in a free state, without counter-force from the cover 60. The body edge can be defined for this purpose be like a cut line defining a connector along which an elastic twist or bending of the strip is possible.
