Description

  The invention relates to a folding box comprising a bottom, and a cover which is preferably also in the form of a section, which is fixed to the folding box so as to be able to pivot or to be able to be at least partially

opened by pivoting.

  The invention also relates to a cut-off piece for manufacturing such a folding box, comprising a bottom, and a cover that can at least partially pivot or be opened by pivoting, which are interconnected by means of a back, knowing that on the side opposite the back, the bottom is connected to an inner front wall member and the cover to an outer front wall member through a ridge

  folding or similar deformation means.

  Finally, the invention relates to a method for producing a folding box which is folded from a cut-out piece provided with a bottom and a lid which are interconnected at their longitudinal edges facing each other through of a back and which have at their opposite longitudinal edges front wall elements, knowing that the lid and the bottom are connected on each side to

side wall elements.

  Various folding boxes are already known which have a bottom, and a lid also in the form of a box or cut, which are pivotally connected to one another. These previously known folding boxes are usually

  used to package cigarillos, pralines or similar luxury goods.

  To manufacture such folding boxes, it is known to initially manufacture the lids or funds in the shape of a box or cut, then to pose in the bottom a quadrangular projecting piece, before sticking on the outside of the cover and the In this case, a paper outer film is applied, where appropriate printed or decorated in a similar way, which is then cut on three sides in the area of the separation plane between the cover and the bottom. The fourth side of the outer film which is not cut then forms the necessary hinge between the cover

and the bottom.

  Since this folding box is composed of several separate pieces that must be interconnected, the manufacture of this folding box previously

  known is by comparison expensive and complicated.

  Therefore, it has also already created a folding box of the kind mentioned in the introduction, which is composed of a single cut piece, which is available to the user in the form of a prefabricated packaging and already glued to the level of the front wall elements, but open to the side. This prefabricated folding box is filled by the users by its two front faces, then glued, before slitting in a next step of the process the folding box on all

  sides, with the exception of the back that serves as hinge.

  This folding box of the kind mentioned in the introduction which is previously known has a comparatively lower manufacturing cost, but once opened, it is impossible to close it. In addition, a closure guaranteeing

  the authenticity is not provided on this folding bed previously known.

  Therefore, before delivering it, the user must still close it with a tax cuff, a closing label or a film made of

transparent plastic.

  The object of the invention therefore consists in particular in creating a folding box of the kind mentioned in the introduction which can be manufactured at low cost and which, when filled, requires for its closure no separate closure means such as a cuff tax or plastic packaging film. In addition, the object of the invention is also to create a blank and a method for

make such a folding box.

  In the case of the folding box of the kind mentioned in the introduction, this object is achieved by the fact that the bottom and the cover are connected by the edges of their front wall elements facing at least one weakening zone. in order to be torn off, weakening zone which constitutes a closure

guaranteeing authenticity.

  In the case of the folding box according to the invention, the bottom and the cover have front wall elements which are connected by their edges facing weakening zones so as to be torn off. These weakening zones hold the front wall and lid wall elements together, without the need for a tax cuff, closure tag or plastic wrapping film as an additional means for close and pack the box. The weakening zones also constitute a closure guaranteeing the authenticity which, once the zones

  of weakening were torn and separated, shows that the folding box was opened.

  It is appropriate for the weakening zones to be realized as perforations. In this regard, a preferred embodiment according to the invention provides that, when the box is closed, the cover passes over an inner front wall member of the bottom protruding from an outer front wall member, which the zones weakening means are formed by perforations which delimit a preferably trapezoidal or semicircular projection on the front wall member of the lid, and that this projection of the lid can be removably attached to the bottom to close the box. The inner front wall member protruding from the outer front wall member allows, at least in this area, a larger filling height. Since the cover passes over the inner front wall element, the folding box according to the invention is hermetically sealed there. The lug-shaped protrusion on the outer front wall member of the lid, which is, for example, made semi-circularly, can be releasably secured to the bottom without any separate securing means and allows for repeated closing of the lid. the folding box

according to the invention.

  To do this, it is appropriate that the bottom has on its inner front wall member an insertion slot or an open-edge insertion cut made to the die to releasably fix the lug-shaped projection provided on the cover, which is disposed in the area of the inner front wall member protruding from the outer front wall member. This insertion slot can be made either in the form of an elongated cut made to the die, or in the form of an elongated notch which conveniently comprises at its two ends auxiliary cuts oriented transversely to the slot insertion to facilitate the insertion of the tab-shaped projection. Instead of the insertion slot, the open-edge insertion cut made to the die can also be coordinated and co-operate with the tab-shaped projection, knowing that a clamping effect on the tab-shaped projection, including an insertion lug, in the closed position allows a

repeated closing.

  In order to be able to fill the box as much as possible and seal it hermetically, it is advisable to provide on each side of the bottom internal wall elements which protrude from its lateral external wall elements and which, when the box is closed, are pressed against the inside of the lid, at its

external wall elements.

  The solution according to the invention in the case of the cut piece of the kind of that mentioned in the introduction consists in particular in that the external front wall element connected to the cover has a longitudinal slot which delimits the line of separation between a bottom and a cover of the cut piece folded so as to form a folding box, and in that this longitudinal slot is interrupted by at least one rod forming bridges of the outer wall element, which strip serves as a detachable or tear-off closure guaranteeing the authenticity between the bottom and the lid. The invention also provides that, on each side of the bottom, there is provided a lateral inner wall element and on each side of the cover is provided a lateral outer wall element, and that these wall elements are respectively connected to the bottom and

  to the lid by means of a folding edge.

  A particularly advantageous development of the invention provides that the rear wall element and / or the outer front wall element is connected on either side to a spacer lug by means of a folding edge or a similar deformation means and that the longitudinal slot opens on each side in preferably semi-circular die cuts made in the matrix or in auxiliary cuts oriented transversely to the longitudinal slot, which are provided in the connection zone between the tabs and the outer front wall element. The folding box according to the invention can thus be made available to the user in the form of a prefabricated packaging glued at the front wall elements of the cut piece, but open on the side. After being filled, the folding box is closed by the user by gluing the side wall elements of the box. By notching the lateral outer wall elements, as well as the adjacent zone of the lateral lugs, the manufacture of the folding box according to the invention is completed. Die cut-outs in the connection area between the intermediate tabs and the front wall member allow, when notching the outer wall members, certain tolerances between the longitudinal slot made in the front wall element.

  during manufacture and the cuts made by the user in the sides of the box.

  The completed folding box can then be opened by tearing the chopsticks forming

  bridges that serve as a closure guaranteeing authenticity.

  The invention provides that the longitudinal slot delimits, preferably in the center, a preferably trapezoidal or semicircular projection which is directed towards the free peripheral area of the outer front wall element, and

  that in this area of the longitudinal slot, are in particular provided the chopsticks.

  According to a development of the invention, the inner front wall member has an insertion slot or an insertion cut made to the die to secure

  detachable manner the lug-shaped projection when the cut piece is folded.

  In the case of the method of the kind mentioned in the introduction, the solution according to the invention consists in that, in a first step, it is cut or similarly cleaned in the outer front wall element adjacent to the lid a longitudinal slot which is interrupted by at least one strip forming bridges, in that in the following stage, the free peripheral area of the external front wall element is adhesively bonded or fixed. inner front wall element adjacent to the bottom, and in that after filling the box by at least one side and after having glued the adjacent inner side wall elements to the bottom and / or the intermediate tabs provided on each side of the back and of the outer front wall element on the free peripheral zone of the lateral outer wall elements, these lateral outer wall elements, as well as, if appropriate, the intermediate tabs connected thereto are similarly slit or open in the area of the lateral outer wall elements, approximately at the height of the longitudinal slot, up to a notch disposed in the extension of a folding edge or similar deformation means provided in the form of a pivot axis for the lid.

  Other features of the invention are indicated in the description

  hereinafter of an embodiment of the invention in relation to the claims and

  the drawing. The different characteristics can be implemented separately or

  combined with each other in an embodiment according to the invention.

  The figures show: FIG. 1 a cut-off piece for producing a folding box having a bottom in the form of a box or a box, and a cover, if any, also in the form of a box or box, which are interconnected at the level of a wall element amière; Fig. 2 a folding box shown in perspective, which is folded from a cut piece similar to that of FIG. 1; Fig. 3 a folding box similar to that of fig. 2 shown in perspective, the lid of this folding box can only be partially opened by pivoting; and

  Fig. 4 a cut piece for making the folding box shown in FIG. 3.

  Fig. 1 shows a cut piece 1 in one piece to manufacture a folding box 2 according to FIG. 2. The cut piece 1 has a bottom 3 and a cover 4, which are interconnected by means of a back 5. The back 5 has a folding edge or a similar deformation means 6 which is provided (e) as an axis

  pivoting between the bottom 3 and the lid 4.

  While the bottom 3 is connected by its opposite side to the back 5 to an inner front wall member 7, an outer front wall member 8 is provided on the side of the lid 4 which is opposite the back of the box. On each side of the bottom 3 is provided a lateral inner wall element 9 and on each side of the cover 4 is provided a lateral outer wall element 10. The bottom 3 is connected to the inner front wall element 7 and the elements of lateral inner wall 9, and the cover 4 to the outer front wall element 8 and to the lateral outer wall elements 10, and this also via a ridge

  folding or similar deformation means 11.

  As shown in fig. 1, the back 5 and the outer front wall member 8

  are connected on each of their two sides to an intermediate tab 12.

  The cut piece 1 can be folded to form the folding box 2 shown in FIG. 2. The folding box 2 has a bottom 13 and a cover 14, which are made in the form of a box or section and which are interconnected by their rear wall members 5a, 5b so as to be pivotable along of a folding edge 11. The rear wall elements Sa, 5b of the bottom 13 and the cover 14 are

  formed by the back 5 of the cut piece 1.

  Fig. 1 indicates that the bottom 13 and the cover 14 are connected by the edges of their outer front wall elements 8a, 8b facing several weakening zones so as to be torn off, weakening zones which form a closure ensuring the authenticity already open in fig. 2 and which are here made as perforations 15. These perforations 15 delimit between them rods forming bridges 16 which interrupt a longitudinal slot 17 in the

cut piece 1.

  When the cut piece 1 is folded, the longitudinal slot 17 delimits the outer front wall member 8a of the cover 14 and the outer front wall member 8b of the bottom 13. The bottom 13 has the inner front wall element 7 which exceeds

  the outer front wall element 8b of the bottom 13.

  On the sides of the bottom 13 are provided the lateral inner wall elements 9, which also protrude from the outer side wall elements lob of the bottom 13. When the folding box 2 is closed, the inner front wall member 7, as well as the lateral inner wall elements 9, which facilitate the complete filling of the box, are covered by the outer front wall element 8a and by the lateral outer wall elements 10a of the cover 14, i.e. in the closed position, the inner wall elements 9 are pressed against the inner face of the lid 14,

  level of its outer wall elements 10a.

  In the area of the perforation 15 located approximately in the center of the outer front wall member 8, the longitudinal slot 17 defines a projection on the front wall member 8 of the lid 14, which is approximately semicircular in FIG. 1 and rather trapezoidal in fig. 2. On the cut 1, this protrusion 18

  is directed outwards towards the free peripheral zone of the front wall element 8.

  The tab-shaped projection may be removably attached in an insertion slot 19 which is disposed on the portion of the inner front wall member 7 protruding from the outer front wall member 8b. The protrusion 18 and the insertion slot 19

  allow the folding box 2 to be closed repeatedly.

  In order to manufacture the folding box 2 and make it ready for use, the longitudinal slot 17 is first cut out of the die in the outer front wall element 8 which abuts the cover 4 of the cut piece 1, a slot which is interrupted by the bridge rods 16. In a subsequent step of the method, the free peripheral zone 8b of the outer front wall member 8 is adhered to the inner front wall member 7 which is adjacent to the bottom 3. The blank 1 may be made available for use in this prefabricated condition, the sides of the

box being still open.

  The prefabricated folding box 2 is filled by the user by at least one side, before gluing the intermediate tabs 12 provided on the back 5 and the outer front wall element 8 on the free peripheral area 10b of the outer wall elements. side and to be able to close the folding case 2. The intermediate tabs 12 and glued between the inner wall elements 9 and the outer wall elements 10 close

  well inside the box, even in the corners of the folding case 2.

  After filling the box by the side, the manufacture of the folding box 2 is completed by notching the outer wall elements 10 and the intermediate tabs 12 connected thereto along the cutting lines L Notching the elements 10 of the outer part 10 of the cut piece 1 forms the lateral outer wall elements 10a and 10b of the cover 14 and the bottom 13. In order to compensate for certain tolerances that may appear between the longitudinal slot 17 produced during the manufacture and the notches in the external wall element 10 made by the user, the cut piece 1 has, in the connection zone between the intermediate tabs 12 and the external front wall element 8, cuts made to the matrix 21 into which the slot opens longitudinal 17 and which are here made circular. These cuts made to the matrix 21 prevent a remainder of material remains between the front wall element 8b and the part of the tabs 12 which remains on the lid 14, which could remain

  possibly hinder the easy opening of the folding box 2.

  The folding box 2 can then be opened in a simple manner at the weakening zones formed as perforations 15 which are provided between the front wall elements 8a and 8b of the cover 14 and the bottom 13. These weakening zones covering the longitudinal slot 17 simultaneously form a closure ensuring authenticity, so that a separate closure means such as a tax cuff or a plastic packaging film is useless. Due to the presence of the lug-shaped projection 18 of the longitudinal slot 19 in the area of the perforations 15 and the insertion slot 19 on the inner front wall member 7 of the bottom 13 which cooperates with this projection, the folding case 2 can be closed repeatedly, even after notching its closure guaranteeing authenticity. Since the cut piece 1 is made in one piece, the folding box 2 can be

manufactured at low cost.

  Figs. 3 and 4 represent a folding case 2 'and the cut piece 1' which corresponds to it, these elements essentially corresponding to the folding box 2 and to its

  cut piece 1 according to FIG. 1.

  As shown in fig. 4, the folding case 2 'nevertheless has an insertion slot 19' which is here produced in the form of an elongated slot. To facilitate the insertion of the lug-shaped projection 18, an auxiliary notch 22 oriented transversely to the longitudinal slot is provided at both ends.

  ends of the insertion slot 19 '.

  The dashed lines of delimitation 25 in FIG. 4 show simultaneously another variant which provides on the front wall element 7, in place of the insertion slot 19 or 19 ', an open-edge insertion cut made to the die 19 ", knowing that in the case of this variant, we obtain the removable attachment for repeated closure through the clamping effect exerted by the insertion lug 18 of the cover 4 on the insertion cutout 19 ". This cut made to the matrix 19 "may conveniently be made conically (to facilitate the insertion of the tab of the lid) and with the two auxiliary cutting lines 22 at the bottom and thus form the

  removable attachment of the lid relative to the bottom.

  In order to compensate for certain tolerances by notching the external wall elements 10 and the intermediate tabs 12 connected to the latter, the cut piece 1 'shown in FIG. 4 shows not circular cut-outs made to the die 21 (see Fig. 1), but other auxiliary cuts 23 in the connection zone between the intermediate tabs 12 and the outer front wall element 8, which are oriented transversely relative to the longitudinal slot 17 and are located on the intermediate tabs 12. These auxiliary cuts 23 fulfill the same function as the cuts made to the matrix 21 of FIGS. 1 and 2, but are easier to

achieve.

  While the folding box 2 according to FIG. 2 comprises on the back 5 a folding edge or a similar deformation means 6 which is provided as a pivot axis between the bottom 3 and the lid 4, the lid 4 of the folding box 2 'according to the fig. 3 and 4 is further or in contrast subdivided by such a folding edge or a similar deformation means 6 'which is arranged (e) parallel to the back and made (e) as a pivot axis for the lid. The lid 4 of the folding box 2 'can also be only partially open along this fold line 6' provided on the top of the lid, the comparatively small opening which is then provided can also be of great use when packing small items

cut.

  When completing the folding box 2 ', it is not essential -

  as shown in fig. 4-to cut the outer side wall elements 10 to the intermediate tabs 12 provided between these outer wall elements 10 and the back, on the contrary, it may suffice to notch or open similarly these elements external side wall 10, as well as, if appropriate, the intermediate tabs 12 connected thereto at the longitudinal slot 17, to a notch 24 of the lateral outer wall elements 10 located in the extension of the ridge Folding 6 '. The folding box 2 comprises a bottom 13 and a cover 14 which is fixed to the folding box 2 so as to be able to pivot or to be at least partially open by pivoting. In the case of the folding box 2, the invention provides that the bottom 13 and the cover 14 are connected by the edges of their front wall members 8a, 8b facing at least one weakening zone 16 so as to could be

  torn off, weakening zone which constitutes a closure guaranteeing authenticity.

  Since the bottom 13 and the cover 14 of the folding box 2 according to the invention are interconnected by means of this weakening zone 16, it is possible to avoid using separate closing means such as a tax cuff, a label

  closure or plastic packaging film.
