Description

Description
The invention refers to a folding box for rod-like deep-frozen food or other deep-frozen foods, which is made of a cardboard with a coating of a polyolefin on the inner face according to the preamble of claim 1.
Folding boxes according to the invention are used for fish fingers, vegetable fingers or other rod-like deep-frozen food, vegetables or other deep-frozen foods. Due to the said intended purpose, materials that are compatible with foodstuffs are used. A primary fibre cardboard (also called 'virgin fibre cardboard') is always used as the starting material, since a secondary fibre cardboard (also called 'recycled cardboard') presents problems for hygienic reasons. The primary fibre cardboard is coated with polyethylene on the inner face so that the material does not become saturated with fat or respectively liquid. The coating consisting of polyethylene is extruded onto the cardboard.
Known folding boxes for deep-frozen food can be opened by breaking open at least one adhesive bond between adjacent walls of the folding box. Also known are folding boxes for deep-frozen food with a tear strip defined by a perforation, which can be opened by detaching the tear strip along the perforation. Reclosing after removing deep-frozen food is not possible, which makes handling the folding box and storing remaining deep-frozen food difficult. This is a particular disadvantage with storage packages that are dimensioned for a plurality of meals. For example, there are folding boxes for fish fingers, which can accommodate 1 x 15, 2x10 or 2x16 fish fingers and are routinely only partly consumed in one meal. DE 20 2009 009 934 U1 describes a folding box for deep-frozen food, which is made of primary fibre cardboard with a coating of polyolefin, a tear strip and a reinforcement strip bonded to the coating of polyolefin along the tear strip. A reinforcement strip is arranged in an oblong recess along the inner face of the tear strip. The tear strip runs all the way round the walls, so that the folding box can be separated into two parts. At least two walls, which oppose each other, each have a fold line in the centre, adjacent to the tear strip. Thanks to the reinforcement strip, the tear strip is easy to open. Once the folding box has been separated into two parts, the larger part can be used as a container for remaining deep-frozen food and the smaller part as a lid that serves to reclose the larger part. The fold lines make it possible to compress the folding box somewhat at the opened end so that it is easier to place the detached lid thereon. A disadvantage of the known folding boxes for fish fingers is that, when opened, only a narrow opening is exposed on the front side. This makes removing fish fingers difficult, particularly if the package is completely full or the uppermost layer offish fingers has been removed.
Consequently, the object of the invention is to provide a folding box for rod-like deep-frozen food or other deep-frozen foods, which is easier to handle. US 2005/011941 A1 describes a reclosable folding box that has a longitudinal side wall, which consists of inner and outer longitudinal side wall parts which at least partially overlap one another and are connected together in a connecting region. A tear strip extends in the longitudinal direction in the outer longitudinal side wall part, between the connecting region of the longitudinal side wall parts and the point of articulation of the outer longitudinal side wall part to the adjacent longitudinal side wall. Adjacent to the closing strip, a trapezoidal closing flap is defined by stamping lines in the outer longitudinal side wall part. In an opened folding box the closing flap can be pivoted inwards around a fold line. A trapezoidal extension protrudes from the edge of the upper longitudinal side wall part, which is connected to an edge strip protruding into the opening. During closing, the closing flap catches behind the extension. The closure is not particularly secure because the extension only protrudes a little above the inner longitudinal side wall part. Furthermore, the closing members become deformed when opened so that reclosure becomes even less secure. Moreover, closure is not intuitive because the closing members are not visible in the closed position.
The object is solved by a folding box with the features of claim 1. Advantageous embodiments of the folding box are given in the sub-claims.
The folding box for rod-like deep-frozen food or other deep-frozen foods according to the invention, which is made of a cardboard with a coating of a polyolefin on the inner face, comprises • four longitudinal side walls which are articulated to one another on the longitudinal sides, wherein one longitudinal side wall consists of inner and outer longitudinal side wall parts which at least partially overlap one another and which are connected together in a connecting region, • two front side walls which are formed from front side wall parts which at least partially overlap one another and which are articulated to transverse sides of longitudinal side walls, • wherein a tear strip extends in the longitudinal direction in the outer longitudinal side wall part, between the connecting region of the longitudinal side wall parts and the point of articulation of the outer longitudinal side wall part to the adjacent longitudinal side wall and • between the point of articulation of the outer longitudinal side wall part to the adjacent longitudinal side wall and the tear strip, the longitudinal side wall, which is formed from at least partially overlapping longitudinal side wall parts, comprises means for reclosing said longitudinal side wall after detaching the tear strip, wherein • the means for reclosing comprise a fold line extending in the longitudinal direction in the upper longitudinal side wall part, between the tear strip and the point of articulation of the outer longitudinal side wall part to the adjacent longitudinal side wall, • characterised in that this fold line comprises at least one interrupted portion, and a cutting line extends between the end points of the fold line next to the interrupted portion, which defines a projection protruding relative to the fold line for articulating the outer longitudinal side wall part to the adjacent longitudinal side wall and • the means for reclosing a stamped-out portion comprise the inner longitudinal side wall part which extends between the end points of the fold line in the outer longitudinal side wall part.
In the folding box according to the invention one longitudinal side wall is formed from two overlapping longitudinal side wall parts. The outer longitudinal side wall part is arranged outside in the overlapping region and the inner longitudinal side wall part inside. The outer longitudinal side wall is provided with a tear strip, which runs in a longitudinal direction, i.e. in the direction in which the points of articulation extend, between the connecting area between the two longitudinal side wall parts and its point of articulation to an adjacent longitudinal side wall. The tear strip preferably extends parallel to these articulations. The tear strip is preferably defined by weakness lines which facilitate its detachment. The detachment of the tear strip enables the release of a part of the outer longitudinal side wall part from the connecting region. Hence said part of the longitudinal side wall part can be folded away together with the adjacent longitudinal side wall articulated thereto and a wide opening of the folding box thereby exposed. The folding box has larger dimensions in the longitudinal direction than in the transverse direction. Therefore, by means of the folding away of a longitudinal side wall, the opening between the longitudinal sides is larger than a conventional opening between the transverse sides. Moreover, the folding box has means for reclosing, which are arranged between the point of articulation of the outer longitudinal side wall part to the adjacent longitudinal side wall and the tear strip. Due to said means for reclosing, the folding box is reclosable when the released part of the outer longitudinal side wall part and the longitudinal side wall articulated thereto are pivoted back into their starting position.
The folding box according to the invention facilitates the removal offish fingers, vegetable fingers and other rod-like deep-frozen food and other deep-frozen foods due to its wide opening between two longitudinal side walls. Moreover, the folding box can be reclosed in order to store remaining deep-frozen food.
According to one embodiment, the connecting region is defined by the edge of the outer longitudinal side wall part remote from the point of articulation of the outer longitudinal side wall part and by the reinforcement strip. According to a further embodiment the entire surface of the outer longitudinal side wall part is connected to the entire surface of the inner longitudinal side wall part in the connecting region. According to another embodiment the longitudinal side wall parts are connected together by points and/or along lines.
According to a preferred embodiment both longitudinal side wall parts are the same length and the same width. Both longitudinal side wall parts are preferably formed congruent or respectively approximately congruent. This is particularly advantageous for a uniform print image on the outsides of the longitudinal side walls. To be exact, the folding box is usually printed on the outside. If the outer longitudinal side wall part only covers a part of the associated longitudinal side wall, matching errors can occur.
According to the invention, the means for reclosing comprise a fold line extended in the longitudinal direction in the outer longitudinal side wall part, between the reinforcement strip and the point of articulation of the outer longitudinal side wall part to the adjacent longitudinal side wall, wherein this fold line has at least one interrupted portion, and a cutting line, which defines a projection protruding relative to the fold line for articulating the outer longitudinal side wall part to the adjacent longitudinal side wall, extends between the end points of the fold line next to the interrupted portion. The means for reclosing according to the invention further comprise a stamped-out portion in the inner longitudinal side wall part, which extends between the end points of the fold line in the upper longitudinal side wall part. Once the released part of the outer longitudinal side wall part and the longitudinal side wall articulated thereto have been closed, the projection can be inserted into the stamped-out portion. For this, the part of the outer longitudinal side wall part remote from the point of articulation can be somewhat pivoted away from the inner longitudinal side wall part, whereby the projection can be directed towards the stamped-out portion and inserted therein. Once the projection has been guided into the stamped-out portion, the part that is folded upwards is pivoted back towards the inner longitudinal side wall part and the projection is locked in the stamped-out portion.
According to a preferred embodiment, the projection is arcuate and/or the stamped-out portion is slot-shaped. This facilitates guiding the projection into the stamped out portion.
According to a further embodiment, a reinforcement strip is applied to the outer longitudinal side wall part on the inner face of the tear strip. The reinforcement strip prevents the tear strip being torn inadvertently and facilitates its detachment. Moreover, the tear strip facilitates the separation of the coating made of polyolefin and prevents the loosening of cardboard fibres. According to a further embodiment, the reinforcement strip is arranged in a recess on the inner face of the tear strip. This improves the mounting of flat-lying or respectively pre-adhered cuts of the folding box. The advantages of the reinforcement strip in a recess are described in DE 20 2009 009 934 U1.
According to a further embodiment, the outer longitudinal side wall part and the inner longitudinal side wall part are connected together between the means for reclosing, in a region that can be detached from the inner longitudinal side wall part. The detachable region of the inner longitudinal side wall part becomes detached when the released region of the outer longitudinal side wall part is folded up following the detachment of the tear strip. The detachment of the detachable region exposes a wider opening in the inner longitudinal side wall part, which additionally facilitates the removal of deep-frozen food. In particular, this opening makes tightly packed, rod-like deep-frozen products easier to grasp.
According to a further embodiment, the detachable region is defined by a weakness line in the lower side wall part. According to a further embodiment, the detachable region extends from the edge of the inner longitudinal side wall part, which is remote from the point of articulation of the inner longitudinal side wall part to the adjacent longitudinal side wall. According to a further embodiment, the detachable region is approximately trapezoidal.
According to a further embodiment, the longitudinal side wall, to which the outer longitudinal side wall part is articulated, has front side wall parts articulated to transverse sides thereof in the form of dust flaps and/or the longitudinal side wall opposing the aforementioned longitudinal side wall has front side wall parts articulated to the transverse sides in the form of further dust flaps. The dust flaps facilitate the reclosure of the packaging since they can be easily guided into the opening between opposing longitudinal side walls, which is exposed due to the opening of the folding box. According to a further embodiment, the dust flaps have a chamfer for this, which lies adjacent to the edge of the longitudinal side wall, to which the outer longitudinal side wall part is articulated.
According to a further embodiment, front side wall parts, which entirely bridge the spacing relative to the opposing longitudinal side wall, are articulated to the transverse sides of the inner longitudinal side wall part, and/or front side wall parts, which partially or entirely bridge the spacing relative to the inner longitudinal side wall part, are articulated to the transverse sides of the opposing longitudinal side wall. These measures favour a print image, which is free of matching errors even on the front side walls.
According to a further embodiment, the front side wall parts, which are articulated to the transverse sides of the inner longitudinal side wall part and the longitudinal side wall opposing this, are connected together.
According to a preferred embodiment, the longitudinal side wall parts and/or the front side wall parts are connected together by adhesive bonding. The adhesion can particularly be over their entire surfaces and/or punctiform and/or along lines.
The folding box according to the invention is preferably cuboidal.
The invention further relates to a folding box filled with fish fingers, vegetable fingers or other rod-like deep-frozen food, or other deep-frozen foods.
In the following, the invention is described in greater detail with reference to the attached drawings of an exemplary embodiment. In the figures:
Fig. 1 shows a plan view onto the outside of a cut of a folding box according to the invention folded flat;
Fig. 2 shows a perspective view diagonally from above and onto a longitudinal side wall and a front side wall of a folding box formed out of the cut from Fig. 1;
Fig. 3 shows the same perspective view of the same folding box with partially detached tear strip;
Fig. 4 shows the same perspective view of the same folding box with a fully detached tear strip;
Fig. 5 shows a different perspective view onto the upper side, the front side wall and the longitudinal side wall of the same folding box opened.
According to Fig. 1, a cut 1 of the folding box according to the invention has four longitudinal side walls 2, 3, 4, 5 which are articulated to one another on the longitudinal sides. The longitudinal side wall 2 comprises an inner longitudinal side wall part 2.1. and an outer longitudinal side wall part 2.2.
Front side wall parts 6.1 to 6.4 and 7.1 to 7.4 of front side walls 6 and 7 are articulated to the transverse sides of the longitudinal side walls 2, 3, 4, 5. The front side wall parts 6.2 and 7.2 and 6.4 and 7.4 are formed as dust flaps and articulated to the transverse sides of the longitudinal side wall parts 3 and 5.
The front side wall parts 6.1 and 7.1 are articulated to the transverse sides of the inner longitudinal side wall part 2.1.
The front side wall parts 6.3, 7.3 are articulated to the transverse sides of the longitudinal side wall 4.
The longitudinal side walls 2 to 5 are rectangular, the longitudinal sides being longer than the transverse sides. Furthermore, the transverse sides of the longitudinal side walls 3, 5 are narrower than the transverse sides of the longitudinal side walls 2, 4.
The inner longitudinal side wall part 2.1 has a slot-shaped stamped-out portion 8 roughly in the centre. The inner longitudinal side wall part 2.1 further has a detachable region 9 which is defined by a weakness line 10. The detachable region 9 is trapezoidal, the wide base of the trapezium falling into the vacant longitudinal side of the inner longitudinal side wall part 2.1. The detachable region 9 ends at a distance from the stamped-out portion 8.
The front side wall parts 6.2, 7. 2 and 6.4, 7.4 each have a chamfer 11, 12, 13, 14 on the edge adjacent to the point of articulation of the longitudinal side walls 3, 5 carrying them, to the inner longitudinal side wall part 2.1 and the outer longitudinal side wall part 2.2.
The upper longitudinal side wall part 2.2 has a tear strip 15 which extends parallel to the point of articulation of the upper longitudinal side wall part 2.2 to the adjacent longitudinal side wall 5. The tear strip 15 is defined by two parallel perforation lines 16.1, 16.2. The perforation lines 16.1, 16.2 are preferably inserted from the external side of the cardboard, out of which the cut 1 is formed. Preferably, they do not extend into the coating made of polyolefin on the inner face of the cardboard.
On both sides of the ends of the tear strip 15, the outer longitudinal side wall part 2.2 has a triangular stamped out portion 17.1, 17.2, 18.1, 18.2, which is intended to facilitate getting hold of one of the ends. An oblong recess 19 extends along the lower side of the tear strip 15. Arranged in the recess 19 is a reinforcement strip 20 made of a plastic tape and fastened to the coating made of polyolefin.
Between the tear strip 15 and the point of articulation of the outer longitudinal side wall part 2.2 to the adjacent longitudinal side 5 there is a fold line 21 which is formed on a succession of pre-folds and score lines. The fold line 21 has an interrupted portion roughly in the centre. There, an arcuate slot 20 extends between the end points 21.1, 21.2 of the fold line 21, which is directed towards the point of articulation of the outer longitudinal side wall part 2.2 to the adjacent longitudinal side wall 5. The slot 22 defines a projection 23.
The region of the outer longitudinal side wall part 2.2, which is arranged on the side of the tear strip 15 remote from the point of articulation to the adjacent longitudinal side wall 5, forms a connecting region 24 for connecting to the lower longitudinal side wall part 2.1.
The fold lines between the longitudinal side walls 2 to 5 and the front walls 6,7 are formed by pre-folds, the weakness line 10 defining the detachable region 9 is a bridged stamping line.
The folding box 25 according to the invention is formed out of the cut, in that the inner longitudinal side wall part 2.1 is folded around its point of articulation to the adjacent longitudinal side wall 3, towards the inner face thereof. Furthermore, the longitudinal side wall 5, including the attached outer longitudinal side wall part 2.2, is folded around its point of articulation to the adjacent longitudinal side wall 4, towards the longitudinal side wall 4. In this case, the outer longitudinal side wall part 2.2 is folded towards the outside of the inner longitudinal side wall part 2.1 at the same time, so that said longitudinal side wall parts 2.1, 2.2 cover each other. The longitudinal side wall parts 2.1, 2.2 are in this context adhesively bonded together in the connecting region 24 outside the tear strip 15 and in the detachable region 9.
The cut 1 can be supplied to the producer of deep-frozen foods by the manufacturer of folding boxes in batches, in the pre-adhered state or in the state in Fig. 1.
The producer of deep-frozen foods folds up the folding box 25 and fills it with goods through the openings on the front side. The openings on the front side are then closed by closing the front side wall parts 6.1 to 6.4, 7.1 to 7.4. For this, first the dust flaps 6.2, 6.4, 7.2, 7.4 are folded into the front openings. Next, the front side wall parts 6.3, 7.3 are folded into the front openings and lastly the front side wall parts 6.1, 7.1 are folded into the front openings and adhesively bonded to the front side wall parts 6.3, 7.3.
The folding box 25 is shown in this state in Fig. 2.
According to Fig. 3 and 4 the folding box 25 is opened by detaching the tear strip 15. In this case the connecting region 24 of the outer longitudinal side wall part 2.2 remains on the inner longitudinal side wall part 2.1. The remaining part of the outer longitudinal side wall part 2.2 can be folded upwards relative to the inner longitudinal side wall part 2.1. The detachable region 9 is in this context detached from the inner longitudinal side wall part 2.1 and remains on the outer longitudinal side wall part 2.2. The folding box 25 can be opened according to Fig. 5, by pivoting the released part of the upper longitudinal side wall part 2.2 and the longitudinal side wall 5 articulated thereto further up.
Rod-like deep-frozen products can then be taken out through the opening 26 between the longitudinal side wall 4 and the inner longitudinal side wall part 2.1. This is facilitated by the further opening 27 which is exposed by detaching the detachable region 9.
To reclose the folding box 25, the released part of the outer longitudinal side wall part 2.2 and the longitudinal side wall 5 articulated thereto are folded back into the position shown in Fig. 4. By folding the adjacent edge strip 28 upwards, the projection 23 defined by the cutting line 21 can be pivoted into the stamped out portion 8. This achieves an effective closure which is easy to release by pivoting the edge strip 28 upwards in order to remove further deep-frozen product.
