For obtaining a portion of the flexible foil 31, the user opens the lid 36 of the packaging container and pulls out a portion of the flexible foil from the roll inside the packaging container. Subsequently, the portion of the flexible foil needed is cut from the roll by the user with the cutting device 10.

[0031] The cutting device 10 comprises a movement guide 11 extending in a longitudinal direction X comprising a central part 12 and two end parts 13, 14 provided at opposite sides of the central part 12. The movement guide 11 is provided with a cutter portion 15 having an operating body 16 and cutting blade 17 for cutting the flexible foil. The cutter portion 15 is movably arranged to the movement guide 11 for movement of the cutter portion 15 along the movement guide 11 upon application of a force in the longitudinal direction X. For cutting the portion of foil needed, the user positions the foil onto the movement guide 11 and moves the cutter portion 15 with his finger onto the operating body 16 along the movement guide 11, so that the cutting blade 17 cuts through the flexible foil and a separate portion of the flexible foil is obtained by the user for further use. In order to further facilitate the use of the cutting device 10 and to enable attaching the cutting device at the bottom part of the packaging box 30, the cutting device is provided with a plurality of clamping arrangements 19 that are spaced apart along the movement guide 11. The clamping arrangements 19 are provided at a side 23 of the movement guide 11 opposite of the operating body 16. Each of the clamping arrangements 19 comprises two clamping elements 20 arranged for clamping a sheet of material between the two clamping elements 20.

[0032] The packing container 30 is provided with a plurality of push-ins 40 in the front wall 32 for allowing a user to realise receiving openings 41 in the front wall 32 opposite to the lid 36. The receiving openings 41 are spaced apart and sized such that a clamping element 20 of the clamping arrangements 19 of a cutter device 10 is receivable in a receiving opening 41 in the front wall 32 for attaching the cutter device 10 to the packing container 30. When the user has acquired a new, unused packing container 30 as shown in Fig. 1, firstly, the user creates the receiving openings 41 in the front wall 32 by pressing the push-ins 40 in the direction of the interior of the packing container 30, see Fig. 2. As is shown in Fig. 1, the push-ins 40 are delimited by perforations lines 46 in the front wall 32. Preferably, the edge 44 between two walls, like the bottom wall 33 and the front wall 32, is not perforated, so that a fold line 43 is formed and the push-ins 40 are folded into the interior the packaging container, in Fig. 1, 2 onto the inner side 45 of the bottom wall 33 of the packaging container 30. As a result, the fold lines 43 of the push-ins 40 now coincide with the edge 44 between the bottom wall 33 and the front wall 32. Alternatively, the push-ins 40, the receiving openings 41, the fold lines 43 can also be provided at an edge between further walls 33, 34, 35 of the packing container 30, like the edge between the rear wall 34 and the bottom wall 33.

[0033] In Fig. 3 the cutting device 10 is attached with its clamping arrangements 19 in the receiving openings 41 created in the front wall 32 of the packing container 30. The clamping elements 20 of the each clamping arrangement 19 were slid onto the double folded wall portions consisting of the push-ins 40 and the bottom wall 33 at the inner side 45 thereof. As a result the clamping elements 20 are clamped on two sheets of folded over packaging wall material, thereby creating an improved attachment due to the higher clamping force. Preferably, the cutting device 10 is removably clamped to the packing container 30, so that the cutting device may be reused for a new packing container 30.

[0034] Fig. 4 shows a cross-sectional view of the cutting device 10 attached to a receiving opening 41 of the packaging container 30. The push-in 40 is detached from the front wall 32 and folded over according to arrow A onto the inner side 45 of the bottom wall 33. The fold line 43 of the push-in 40 coincides with the edge 44 between the bottom wall 33 and the front wall 32. The clamping elements 20 of the cutting device 10 are slid over the two sheets of folded over packing material formed by push-in 40 and bottom wall 33. As a result, the cutting device 10 is firmly clamped onto the bottom wall 33 of the packaging container 30.

[0035] As is shown in Fig. 3, for providing a better connection with the packaging container, the end parts 13, 14 of the movement guide 11 extend in the longitudinal direction X beyond the clamping arrangements 19. To prevent the cutter portion 15 from detaching from the movement guide 11, the end parts 13 and 14 are equipped with end stops 21 to restrict the movement of the cutter portion 15 along the movement guide 11. Furthermore the end parts 13, 14 are provided with a force blocking element 22 arranged for allowing the cutter portion 15 to move to the central part 12 from the end part 13, 14 when the force exceeds a predetermined force level and / or from the central part 12 to the end part 13, 14 when the force exceeds a predetermined force level. As a result, the cutter portion 15 is held in the best position at the force blocking element 22 on the movement guide 11 for cutting the flexible foil laid on the movement guide 11 without obstructing or hampering laying down the flexible foil onto the movement guide 11. The movement guide 11 is provided with a coating arranged for increasing a friction between the movement guide 11 and the flexible foil thereby improving the cutting operation of the flexible foil 31 with the cutter portion 15 by preventing movement of the flexible foil laid down on movement guide 11 during the cutting step.

[0036] As is shown in Fig. 1, 2, the width W of a receiving opening 41 of the receiving openings corresponds to a length D of a clamping arrangement 19 of the plurality of clamping arrangements in the longitudinal direction X of the movement guide 11 thereby preventing movement of the cutting device 10 in the longitudinal direction X of the movement guide 11.

[0037] The combination of packing container 30 with cutter device 10 may be sold together as a kit in stores, or alternatively, each component may be sold separately, as the cutter device 10 can be reused multiple times. Preferably, a length L of the central part 12 of the cutting device 10 in the longitudinal direction X is equal to or greater than a length F of the flexible foil 31 in the longitudinal direction X, so that the flexible foil 31 from the roll is easily laid down onto the movement guide 11 for cutting. The cutting device 10 extends beyond the packing container 30, so that a flexible foil 31 having a length F can be conveniently cut by the cutter portion 15 positioned in the end parts 13, 14 of the movement guide 11.
