The plate (1) comprises two fixed-together parts (2, 3), between which the flange (17) is clamped. The plate (1) is provided with a folding line (7) located near one flange of the box (14) with tangent lines (9, 21) touching the box (14), which extend from the folding line (7), transversely thereto, and with two lines of separation (9, 23), extending from the folding line (7) to the box (14), which are located on the tangent lines (9, 21) and/or on sides of the tangent lines (9, 27) facing away from each other.

Description: PACKAGE AS WELL AS A PLATE AND A BOX SUITABLE FOR SUCH A PACKAGE The invention relates to a package comprising a box which is open on one side and a plate which closes said open side, which box is near its open side provided with at least one flange extending away from said box, whereby said plate comprises two fixed-together parts, between which said flange is clamped. The invention also relates to a plate and a box suitable for such a package. With a package of this type known from British Patent GB-B-1,456,895 the flange surrounding the box is partially clamped between the two parts of the plate. The flange is positioned on the plate near one end of the box. The plate is to that end provided with two cuts 3 extending transversely to the box. The box can be moved into and out of the plate by sliding the flange between the cuts. The flange can be locked against sliding out by means of a separate lip. A drawback of the known package is that products can be stolen from the package in a simple manner without the package showing any signs of this. Another drawback is the fact that the box and the flange need to be rectangular in order to obtain a package of this type. Because of this the amount of material required for the box and the flange is relatively large. The object of the invention is to provide a package wherein the above drawbacks are avoided. This objective is accomplished with a package according to the invention in that said plate is provided with a folding line located near one flange of said box, with tangent lines touching said box, which extend transversely from said folding line, and with two lines of separation extending from said folding line to said box, which are located on said tangent lines and/or on sides of the tangent lines facing away from each other. The flange of a box is clamped between the two parts of the plate, whereby the box projects through a recess in said first part. When the plate is folded in two near one end of the box, the part of the first plate part that is located between the lines of separation and the folding line will remain attached to the folded part of the plate, thus providing room for moving out the box. The flange located near the end of the box will be released and the box can be moved out of the plate. The folding line of the first part is thereby either cut through on sides of the lines of separation facing away from each other by parts of the flange extending on sides of the lines of separation facing away from each other, or torn open by the forces exerted during folding. Because the lines of separation are located on either side of or on the tangent lines it is possible to use a box whose shape is for example adapted to that of the product to be packed, whereby the tangent lines bound the box. The flange may be adapted to the box, so that the amount of material required for the box and for the flange can be minimized. It is not possible to remove products from the package without damaging said package. Any theft of a products from the package will immediately be noticeable. Because the box and the plate are moved apart a forced separation is obtained and the box and the plate can be disposed of separately. One embodiment of a package according to the invention is characterized in that said first part is provided with perforations located on the folding line, which are positioned on sides of the lines of separation facing away from each other. As a result of this the folding line can simply be cut through by means of the flange. Another embodiment of the package according to the invention is characterized in that said lines of separation comprise lines of cut or are provided with perforations. When the lines of separation are lines of cut, relatively little force is required for folding the plate. When perforations are provided, slightly more force is required for folding the plate, whereby perforations are extended into a common line of cut during folding, but on the other hand an additional protection against unauthorized opening is obtained. Another embodiment of the package according to the invention is characterized in that the two parts are folded together. In this way it is possible to obtain a package which is provided with text or illustrations on either side, whilst the plate only needs to be printed on one side. The folded-together and fixed- together sides of the two parts need not be printed. The invention will be explained in more detail hereafter with reference to the drawing, in which: Figure 1 is a perspective front view of a plate of a package according to the invention; Figure 2 is a rear view of the plate shown in Figure 1; Figure 3 is a perspective view of a package according to the invention; Figures 4-6 show the opening of a package according to the invention; Figure 7 shows a detail of the package shown in Figure 3, seen in the direction of arrows VII-VII; Figure 8 shows a detail of the package according to the invention seen in the direction of arrows VIII-VIII; Figure 9 shows a detail of the package according to the invention; and Figure 10 is a front view of a second embodiment of a package according to the invention. Like parts are numbered alike in the Figures. Figure 1 shows a front view of a cardboard plate for a package according to the invention. The plate 1 comprises two parts 2, 3. which can be folded with respect to each other about a folding line 4. The first part 2 has a residual part 6 bounded by lines of cut 5, which can be pressed out of part 1 and which is connected to part 1 in a few points only. The first part 2 is furthermore provided with perforations 8 located on a folding line 7. Lines of cut 9 extending transversely to folding line 7 extend between said perforations 8 and said lines of cut 5. The second part 3 of plate 1 is provided with a groove 10, which is positioned lower, seen in Figure 1, than the parallel folding line 8. The two parts 2, 3 are furthermore provided with eye-shaped recesses 11, by which the package to be formed can be suspended. The side of the plate which can be seen in Figure 1 is printed with text and/or illustrations. Figure 2 shows the rear side of plate 1. The residual part 6 has been pressed out of part 2, thus forming a recess 12 which is bounded by the lines of cut 5. The residual part 6 has been glued to the second part 3, opposite recess 12, whereby the side of the residual part 6 that is provided with text and/or illustrations faces away from said second part 3. The sides of parts 2, 3 that are discemable in Figure 3 are provided with glue. Figure 3 shows a package 13 according to the invention comprising the plate 1 and a box 14 fixed between parts 2, 3 of plate 1. The box 14, which is made of transparent plastic material, comprises a bottom 15 and walls 16 extending substantially transversely to bottom 15. The box 14 is open on one side facing away from the bottom. Near the open side the walls 16 are provided with flanges 17 extending substantially transversely to the walls 16. The package 13 is made in the following manner. Box 14 is filled with products to be packed (not shown), after which the box 14 is passed through the recess 12 formed in the first part 2, whereby the flanges 17 will abut against the rear side of said first part 2. Then the second part 3 is folded about folding 4 in the direction shown by arrow Pl of Figure 2, and the parts 2, 3 are glued together, whereby the flanges 16 are retained between the two parts 2, 3 and the open side of the box 14 is closed by second part 2. The sides of parts 2, 3 that are provided with texts and/or illustrations are present on the outside of the package 13. The text and/or illustration printed on residual part 6 is (are) discemable through the transparent box 14. The recesses 11 present in parts 2, 3 are positioned opposite each other and the formed package 13 can be suspended from a rack (not shown) by means of the common recess 11. The package 13 can be assembled manually or by means of special machines. Figure 7 shows a detail of the package 13 shown in Figure 3, wherein the distance between the two parts 2, 3 is illustrated larger than in actual proportion for the sake of clarity, so that a glue 18 connecting the parts 2, 3 is discemable. The flanges 17 are clamped between the parts 2, 3. The glue 18 is a purpose-developed, natural latex- based rubber glue which permits silkscreen printing, which under the influence of pressure adheres to the sides of the plate 1 on which glue is present, but which does not adhere to the flanges 17. Preferably the glue comprises 0.005-2.1 kg of aqueous tinted pigment paste, 20-40 kg of water, 0.2-8 kg of carboxymethyl cellulose or otherwater-soluble cellulose derivates, 2-16.8 kg of hexylene glyclol, 0.2-8.2 kg of pH-regulating substances and 20-90 kg of rubber. The opening of the package 13 with a view to taking out products (not shown) present in the box takes place as follows. The two parts 2, 3 are jointly folded in two about the folding line 7, which comprises the perforations 8, and the groove 10 in a direction indicated by arrow P2 (see Figures 4 and 5). Part 19 of first part 2, which is bounded by the folding line 7, the lines of cut 5 bounding recess 12 and the lines of cut 9 extending between folding line 7 and line of cut 5, is attached to the folded part 20 of plate 1, and as a result is likewise tilted with respect to box 14, as a result of which the flange 17 located near one end 21 of the box 14 will be released. Figure 8 is a larger-scale illustration of a detail of the package 13, seen in the direction of the arrows VIII-VI11 in Figure 4. After part 20 of plate 1 has substantially completely been folded in two against part 3, the box 14 is moved with respect to the plate 1 in a direction indicated by arrow P3, whereby the flanges 17 slide between the parts 2, 3 (see Figures 6 and 9). The perforations in the first part 2 are partly cut open by means of the flanges 17, after which the box 14 can be completely moved out of plate 1 and the products packed in said box can be removed therefrom. The text and/or illustrations on plate 1 are not damaged when the package 13 is opened and can also be examined after the package has been opened. Then the cardboard plate 1 and the plastic box 14 may be stored or disposed of separately. It will not be possible to move the box 14 back between the parts 2, 3 of the plate 1, because the glue 18 will cause the parts 2 and 3 to stick together after the box 14 has been moved out of the plate 1. It is also possible to apply the glue 18 only to those parts of the plate 1 that do not come into contact with the flanges 17. Figure 10 shows a second embodiment of a package 1 according to the invention, whereby the box 14 has an irregular shape adapted to the product to be packed. The box 14 is provided with a flange 17, which is clamped between the two plate parts 2, 3. The package 1 is provided with a folding line 7 spaced from the box 14 by some distance, about which the plate parts 2, 3 can be folded. Two tangent lines 21 extend from folding line 7, which touch the box 14 in points 22. The points 22 are spaced apart, seen in a direction parallel to the folding line 7, by a distance which corresponds with the width of the box 14. The tangent lines 21 are imaginary lines and need not be physically discemable on the package 1. The package 1 is furthermore provided with two lines of separation 23, which are positioned on sides of the tangent lines 21 facing away from each other and which extend from folding line 7 to box 14. The lines of separation 23 may touch the box 14 in points 22 or at a location beyond points 22. Both possibilities are illustrated in Figure 10. The lines of separation 23 are preferably provided with perforations. The first part 2 is also provided with perforations 8 on the folding line 7, which are positioned on sides of the lines of separation 23 facing away from each other. In order to open the package 1 the part of the package located above folding line 7 is bent in a direction indicated by arrow P2, as a result of which a tensile force is exerted on the part 19 of first part 2, which will cause the perforations on the lines of separation 23 and on the folding line 7 to be torn open. The part 19, which is bounded by the folding line 7, the box 14 and the lines of separation 23 is fixed to the folded part 20 of plate 1, and is folded in the direction indicated by arrow P2 together with part 20. After said folding the box 14 is moved in the direction indicated by arrow P3 until the flange 17 is fully released and the box 14 has been detached from the plate parts 2, 3.
