Description

Field of the invention

[0001] This invention relates to a packaging box, particularly an orthohedric shaped box with rectangular sides, of the type that is made by folding and sticking a die-cut laminar material such as cardboard, which is simultaneously suitable for shipping a group of units of manufactured articles, for storing them and for supplying them by removing each unit for it to be used at its destination.

[0002] It has been envisaged in this packaging case, to incorporate a closing device intended to ensure in a releasable manner the closure thereof once the hinged lid provided is open, whereby the lid has a longitudinal flange which, in the closed position, backs inwards against the back of the front face of the box and has a bolt eye arrangement in correspondence with the closing device.

[0003] Also it has been envisaged that said packaging box be provided with an arrangement, such as a safety seal, whereby an indication is provided if the box has been opened before the first time its contents is used.

State of the art

[0004] Packaging boxes are known, for example via Spanish Utility Model No. 200002399, inter alia, where the top of the front face forms a die-cut rectangular tongue piece, which has two folding lines which give it its articulated nature, and the longitudinal flange of the box's hinged lid has, on level with the inner face of said hinged lid, a bolt eye arrangement in the form of a narrow horizontal groove in which the free end of said articulated, rectangular tongue piece is inserted.

[0005] This bolt eye arrangement does not guarantee the stability of the lid when the position of the box is inverted, because the free end of the articulated rectangular tongue piece, which is inserted with a simple friction-based adjustment into the narrow horizontal groove, slides easily if a small opening force is applied to the hinged lid when the position of the box is inverted, and this can lead to the box opening and spilling its contents.

[0006] Moreover, in order to guarantee the contents of the packaging box warranty seals are usually used, in the form of adhesive stamps or labels. On many occasions, owing to the environment in the area where the box is located or other factors, these seals come unstuck from the packaging box thereby forfeiting their role as warranty seals. Packaging boxes are known, for example in Spanish Utility Model application No. 8702832, in which the lid, or another part of the packaging, has an arrangement that acts as a warranty seal and which is made up of an area delimited by a perforated line, so that when said area is scratched the packaging box opens and, at the same time, a hinged lid is formed. However, this type of hinged lid suffers from the drawback that it lacks a closing device.

Disclosure of the invention

[0007] In order to overcome the drawbacks mentioned above, the solution has been adopted whereby in a packaging box with a hinged lid, the actual hinged lid forms the warranty seal element and includes a closing device of the articulated tongue piece type, with retention means being provided for said tongue piece, which secure the closing position of the hinged lid.

[0008] According to this solution, and taking into account the prior art considered, a packaging box has been developed, by folding and sticking a die-cut laminar material, which comprises a hinged lid that closes in a releasable manner, with said hinged lid being provided with a longitudinal flange which, in the closing position of said hinged lid, backs inwards against the front face of said packaging box, characterized in that the top of said front face of the packaging box is provided with a die-cut tongue piece, said tongue piece having folding lines that give it its articulated nature and ending in an arrow shaped area, and said longitudinal flange of the hinged lid having, complementarily to said tongue piece, a narrow horizontal rectangular opening that, as a continuation of one of its two larger sides, has end cuts that determine triangular end areas that are elastically deformable by the action of inserting and/or extracting, in a voluntary and forced manner, said arrow shaped area of the tongue piece, with the length of said narrow rectangular horizontal opening being greater than the width of the body of said tongue piece and smaller than the maximum width of said arrow shaped area of the tongue piece.

[0009] Preferably, said narrow rectangular horizontal opening provided on the longitudinal flange is separated from the folding line provided between said longitudinal flange and the rest of the hinged lid, and in a substantially centered position with respect to the width of said longitudinal flange.

[0010] Preferably, the two side ends of the top face of the packaging box according to the invention, which forms the hinged lid, extend in cantilever wings that are part of the side walls of said packaging box and which have perforated lines along the folding lines provided between said cantilever wings and the top face of the packaging box.

[0011] Preferably, the top face of the packaging box according to the invention, which forms the hinged lid, has: on its rear side, a hinged line related to the rear face of said packaging box; on its front side, a folding line from which said top face of the packaging box extends forming the longitudinal flange provided with the narrow rectangular horizontal opening; and, on its two side faces, which are adjacent to said rear and front sides, the cantilever wings through which there extend the two side ends of said top face of the packaging box; and the front face of said packaging box, on to which the longitudinal flange backs inwards, is provided with the articulated tongue piece and ends in an arrow shaped area that fits into the narrow rectangular horizontal opening of said longitudinal flange.

[0012] Preferably, the side walls of the packaging box according to the invention are formed by the association of the cantilever wings, through which there extend the two side ends of the top face of said packaging box, with cantilever wings though which there extend the front and rear faces and the bottom wall of said packaging box, with said cantilever wings being in coplanar juxtaposition forming opposite pairs of two and two, and on the surfaces of each pair of said cantilever wings, which faces the equivalent pair in the assembly of said packaging box, is provided a layer of self-adhesive glue with mutual and exclusive affinity to the equivalent cantilever wings that they are facing when packaging box is assembled.

[0013] Preferably, the tongue piece has a handle consisting of a die-cut lug in the arrow shaped area of said tongue piece, with said handle being contained, in the closed position of the hinged lid, in the same plane that contains said arrow shaped area of the tongue piece.

[0014] Preferably, the front face of the packaging box according to the invention has, on its top edge, a notch that makes the longitudinal flange accessible to a finger on a user's hand.

Detailed description of an embodiment of the invention

[0016] The invention applies particularly to an orthohedric shaped packaging box with rectangular faces, which is made by folding and sticking a die-cut laminar material that preferably consists of a type of cardboard, and which is suitable for the packaging and guaranteed shipment of a group of units of manufactured articles, for storing them and for supplying them by removing each units for it to be used at its destination.

[0017] According to the invention, this packaging box has warranty seal means and closing means, the latter being intended to re-close the packaging box in a releasable manner after its seal has been removed, via the hinged lid that is part of the packaging box. Therefore, said hinged lid has a longitudinal flange which, in the closed position, backs inwards against the back of the front face of the packaging box and which, in such a position, provides means that behave like a bolt eye device for means acting as a bolt.

[0018] Fig. 1 shows a material embodiment of a packaging box 1 according to the invention, without defining either the length of said packaging box 1, which can vary according to the longitudinal length of the articles to be packaged, or its height or depth, even though these sizes are indicated in the drawings as if they were defined. Moreover, the number of closing means provided on the front of said packaging box 1 might also vary, depending on the length of packaging box 1.

[0019] As shown in Figs. 1 and 2, and detailed in Figs. 3, 4 and 5, packaging box 1 has, on the top of its front face 2, a die-cut tongue piece 3 that has two folding lines 4, which give it its articulated nature, and ends in an arrow shaped area 5. Hinged lid 7 of packaging box 1 has a longitudinal flange 6, which has bolt eye means consisting of a narrow rectangular horizontal opening 8 that has two end cuts 8A, arranged as a continuation of one of the two larger sides of said narrow rectangular horizontal opening 8. Said end cuts 8A determine, in said narrow rectangular horizontal opening 8, triangular end areas 9 that are elastically deformable around a line 9A by the action of inserting and /or extracting, in a voluntary and forced manner, the arrow shaped area 5 of tongue piece 3. The length of narrow horizontal opening 8 is greater than the width of the body of tongue piece 3 and smaller than the maximum width of the arrow shaped area 5 at the end of said tongue piece 3.

[0020] As can be seen in the cited figures, the bolt eye means, in the form of narrow rectangular horizontal opening 8, are separated from the folding line provided between said longitudinal flange 6 and hinged lid 7 and are arranged in a substantially centered position with respect to the width of said longitudinal flange 6.

[0021] As shown in said figures, one of the faces of packaging box 1, in particular the one that must form hinged lid 7, has: on its rear side, a hinge line 10 retaled to rear face 11 of packaging box 1; on its front side, a folding line 12 that is shared with an extension of hinged lid 7 that forms longitudinal flange 6 that has at least some elastic bolt eye means in the form of narrow rectangular horizontal opening 8; and, on its two lateral sides 13, which are adjacent to the two sides considered above, perforated lines 14, as warranty seal means, which are shared with two cantilever wings 15 which, as shown in Figures 6 and 7, are part of the side walls of packaging box 1.

[0022] The face of packaging box 1 that forms front face 2 thereof, onto which said longitudinal flange 6 backs inwards, has an articulated tongue piece 3, which ends in an arrow shaped area 5 designed to fit, like a bolt, into said elastic bolt eye means consisting of narrow rectangular horizontal opening 8 arranged on longitudinal flange 6.

[0023] As can be seen in said figures, tongue piece 3 has a handle consisting of a die-cut lug 16 in arrow shaped area 5 of tongue piece 3. In the closed position of hinged lid 7, said handle is contained in the same plane as that which contains said arrow shaped area 5 of tongue piece 3.

[0024] Fig. 7 illustrates the fact that the side walls of packaging box 1 are formed by the association of cantilever wings 15, through which there extend the side ends of the face of packaging box 1 that corresponds to hinged lid 7, with cantilever wings 20 through which there extend front 2 and rear 11 faces and bottom wall 17 of said packaging box 1. In order to form said side walls, cantilever wings 15, 20, are in coplanar juxtaposition opposite one another in pairs of two. The surfaces of each pair of said cantilever wings 15, 20 are provided with a layer of self-adhesive glue 18 with mutual and exclusive affinity to the equivalent cantilever wings that they are facing when packaging box 1 is assembled.

[0025] The figures show that front face 2 of packaging box 1 has on its top edge a notch 19, corresponding to tongue piece 3, which allows a finger on a user's hand to access longitudinal flange 6 so as to facilitate the opening of said packaging box 1.
