EP2112078B1 - Folding box - Google Patents

Abstract

The box (1) has a cover part (6) hinged at a rear side wall (4), and provided on an intermediate wall (7) in an end position in a flat manner. An insertable tongue (8) is rigidly formed at a cover part for closing the folded box, and is inserted into an insertion opening arranged on the intermediate wall by a movement along a support surface formed by the wall (7). A locking component e.g. detent (10), is formed such that the component is brought into a locking position during movement of the cover part. The detent is arranged on a lower side of the cover part turned towards the wall (7).

Description

The invention relates to a folding box according to the preamble of claim 1. Such folding boxes are usually made of cardboard or cardboard laminate and can be made of one or more blanks. The carton is designed such that it can be opened only when targeted force by the user. Children should not or not be able to open the box.

A comparable carton, which deals with the problem of child safety, is for example from the EP 1 323 635 A1 known. The folding box shown therein has a hinged on a cover part Einsteckzunge with a locking strip which engages behind the locking bar with the lid part closed. As insertion for the insertion tongue a recess is provided on a parallel to the folding box bottom extending intermediate wall. The locking bar is formed by the intermediate wall. To close the carton, the V-shaped insertion tongue-locking strip arrangement is pivoted and inserted from above into the insertion. To open the box, the latched locking bar must be moved, the access is made by means of warranty protected by unlocking openings through which a release force on the locking strip is exercisable. In practice, it has been shown that this carton satisfies higher demands for child safety only insufficient. For as soon as the warranty section of the unlocking has been removed, the box can be opened relatively easily for children. Next is the closing process, especially the reclosure of the box rather cumbersome.

Next is out US 2,974,854 a folding box is known, on which on a cover part insertion tongues are arranged, which are plugged in the closure of the box in insertion openings on a lid intermediate wall. The insertion openings and the insertion tongue are designed so that they can be inserted or loosened by a lateral displacement.

US 1,837,602 also shows a carton having the features of the preamble of claim 1, with an integrally formed on a cover part Einsteckzunge, which can be inserted into a slot in an intermediate side wall. The insertion tongue has folded-over projections, which latch into the slot after the first insertion and thus form a guarantee closure.

It is therefore an object of the present invention to avoid the disadvantages of the known, and in particular to provide a carton of the type mentioned, which meets high standards of parental control. The box should continue to be easy to use.

According to the invention these objects are achieved with a carton having the features of claim 1. To close the carton, the lid part can first be folded or folded until it lies on the intermediate wall, whereupon the cover part can be moved by a sliding movement on the intermediate wall in the blocking position. Advantageous locking means ensure that the blocking position is automatically reached during the movement of the cover part. The blocking position can be predetermined for example by a latching connection, in which the blocking means can be locked together. In the locked position, the lid part can not be opened. The operation of the opening process, in which the cover part must first be moved by targeted force in the opposite direction to the closing direction in order to then be able to be unfolded, is difficult for children to see through.

The child safety is increased by the fact that the cover part for specifying the blocking position has at least one latching lug, which is arranged on one of the intermediate wall facing the underside of the lid part and which is latched with a stop associated with the intermediate wall. In the blocking position, the latching nose can thereby engage in a latching manner with a stop, which can preferably be formed by a corresponding edge in the intermediate wall. For an advantageous latching connection may be arranged on the intermediate wall a complementary latching lug recess into which the latching lug is receivable in the locked position.

In a first embodiment, the at least one insertion tongue is rigidly formed on the cover part. The rigidly integrally formed insertion tongue can be created, for example, in that the cover part and the insertion tongue are formed in one piece and in the connection area without material weakening. The rigid design prevents unwanted buckling or folding over of the insertion tongue.

It may be particularly advantageous when the cover part and the insertion tongue formed thereon is formed at least in two layers. The multi-layered design increases the rigid connection between insertion tongue and cover part. This robust construction has considerable advantages in particular for a folding box which is intended for multiple opening and reclosing.

The cover part may consist of at least two cover part sections, which are folded around a fold line and preferably glued together, wherein the fold line or the fold line formed by the fold line forms a front, the insertion opening facing the end of the insertion tongue. Of course, it is also conceivable to form the cover part from two (or more) separate cover part sections.

If the intermediate wall is formed at least two layers, it may be advantageous if the insertion opening for sandwiching the insertion tongue is formed by a gap space between the layers of the intermediate wall. The layers of the intermediate wall thus to some extent form a kind of receiving pocket for the insertion tongue. This arrangement has the advantage that the insertion tongue is advantageously fixed.

The carton is particularly suitable for packaging blisters for tablets, capsules, dragees, etc. Such blisters are known and used for a long time and are characterized by the fact that they consist of a provided with cups for receiving packaged carrier film and a pressure-sensitive flat cover film , To remove the packaged goods, this is pressed through the cover sheet in an area assigned to the bowl. For packaging blisters, it may be advantageous if the intermediate wall is formed as a blister carrier containing two carrier sections, wherein sandwiched between the carrier sections of the blister or is receivable and when the blister carrier is hinged to a front wall of the carton.

Additionally or alternatively, it may be advantageous if a carrier part for packaged goods and in particular for a blister connects to the intermediate wall preferably via a joint fold, which rests in the end position approximately flat on the ground. In the case of a folding box, in which the intermediate wall is designed as a blister carrier, it may be advantageous if the joint fold rests against the front wall at least in a position of use with the blister carrier folded out.

Further, it may be advantageous if the transversely to the rear wall extending transverse side walls of the box side walls are formed as approximately prismatic hollow side walls. These hollow side walls each contain an inner wall, an outer wall and a connecting web. The hollow side walls can be rectilinearly raised from the plane of the floor, wherein in the end position, the intermediate wall is supported or supportable on the connecting web and wherein the intermediate wall for holding the end position by latching means with the hollow side walls is latchingly connectable. The latching means may include the transverse side wall associated latching tongues, which in the end position in each case latching in a cover part associated with the stop, formed for example by a recess engage. The cover part may have corresponding stops which cooperate with the respective locking tongues for producing the latching connection. The locking tongues may be predetermined by cutting lines or by predetermined breaking lines in the connecting web and connect to the inner walls of the transverse side walls. In this case, the latching tongues can be hinged out of the plane of the connecting web during the erection process of the hollow side walls. Of course, it is also conceivable to equip cartons without such locking means.

Further stabilization of the blocking position can be achieved if the folding box has two or more insertion tongues. It may be advantageous if the locking lug is arranged between two insertion tongues. It may be particularly advantageous if, based on a plan view, the latching lug on the mid-perpendicular is predetermined by the two insertion tongues.

In a preferred embodiment, the latching lug is formed by a nose portion, which is folded over relative to the underside of the lid portion forming portion and preferably adhered thereto. Instead of such a one-piece connected to the lid part nose portion of this could also be designed as a separate, flat segment of cardboard, cardboard laminate or plastic.

The locking mechanism for the locking means can be optimized, for example, when the locking lug is particularly exposed to the plane of the lid part. This can be, for example, in a carton with a lid part containing a reach upper and a lower cover portion portion, wherein the lower cover portion portion forms the underside of the cover part, thereby achieve when at least one distance segment between the upper and the lower cover portion portion is arranged to expose the latch from the plane of the lid part.

The at least one spacer segment may be formed from the upper or the lower lid portion, wherein it is folded in an end position relative to the upper and lower lid portion portion.

A particular embodiment is characterized in that a cutting line is provided on the lower lid portion, which separates a web portion from the remaining portion of the lower lid portion, the web portion being raised from the remaining portion of the lower lid portion by the at least one spacer segment. In this arrangement, the locking lug is advantageously glued approximately centrally on the web portion.

The FIGS. 1 to 4 show the folding carton 1 according to the invention (hereafter abbreviated to "box" is used for the sake of simplicity) in different positions.

In FIG. 1 is the box 1 in a use position in which both a cover part 6 and an intermediate wall 7 are unfolded. To close the box 1, the intermediate wall 7 must first be folded. This position is in FIG. 2 recognizable. Then the lid part 6 must be folded until it rests on the intermediate wall 7. After folding in the cover part, the insertion tongues 8 can be inserted into corresponding insertion openings 9. This position shows FIG. 3 , wherein the arrow e indicates the insertion direction.

The box 1 is in FIG. 4 completely closed. In this position, the blocking means described in more detail below are in a blocking position.

As FIG. 1 shows the box 1 consists of a bottom 2, connect to the four side walls 3, 4 and 5. The two transverse side walls, designated by 5, are designed as prismatic hollow side walls. Each hollow side wall has an inner wall 24, an outer wall 25 and a connecting web 26. On the inner walls 24 close latching tongues 27, with which the intermediate wall 7 can be fixed in a rest position (see Fig. 2 ). It can be seen that the latching tongues 27 which are opened relative to the plane of the connecting web 26 project away from the connecting web.

The intermediate wall 7 is designed as a blister carrier. Between two support portions 15 and 16, a blister is sandwiched and fixed therein. From the blister clearly the blister pots 18 are recognizable. Further shows FIG. 1 a likewise provided as a blister carrier support member 21 in which a blister is added in approximately the same way. From this support member 21, a portion 23 can be seen, which is articulated via a hinge fold 20 on the support portion 15 of the intermediate wall 7. Of course, depending on the application, such a carrier part (21) could be dispensed with. Also in this case, in which only one blister packaged in the packaging, it may be advantageous if the previously described Gelenkfalz (20) adjoins for support on the intermediate wall. Thanks to the Gelenkfalzes results in the final position of at least two-ply wall structure in the front wall, creating a stable box can be created.

On the side opposite the intermediate wall 7 side of the box is the cover part 6, which is hinged to the rear side wall 3. The cover part 6 is formed in two layers. On the underside of the lower cover part section is located between two insertion tongues 8 a designated 10 locking lug. This detent 10 acts in the locked position with a (not visible here) recess together (see. FIGS. 2 and 3 ).

FIG. 2 shows this recess 11 which is formed approximately complementary to the locking lug 10. The two locking means 10 and 11 form a latching connection in the blocking position. Laterally next to the recess 11 7 insertion openings 36 for the insertion tabs 8 can be seen on the top of the intermediate wall. The real one However, insertion opening 9 is formed by the gap between the two layers of the intermediate wall 7. Furthermore, it is off FIG. 2 the operation of the latching connection between the hollow side walls 5 and the intermediate wall 7 can be seen. The locking tongues 27 are latched in the corresponding recesses 28 of the intermediate wall 7, whereby a Nachuntenklappen the side walls 5 is prevented.

Out FIG. 3 shows that the last part of the closing process, the cover part 6 must be slid in the e-direction along the partition wall 7 until the locking position is reached. During this sliding movement, the insertion tongues 8 are pushed into the gap space between the two layers of the intermediate wall until the latching connection between the locking means is produced. The insertion tongue 8 is rigidly integrally formed on the cover part 6. Characterized in that the cover part 6 is formed in two layers, an undesired buckling or folding of the insertion tabs 8 is virtually impossible.

The opening of the box 1 can only be done under targeted force. In FIG. 4 the steps required to release the blocking position are indicated by corresponding arrows. First, the box 1 must be compressed in the area of the front and rear wall 3. This can be done for example by means of the thumb and forefinger of one hand. The corresponding forces are marked with F1. With the other hand, the intermediate wall now has to be pressed down approximately in the middle in the area not acted upon by the cover part (the corresponding pressure force is indicated by the arrow F2). Care must be taken to ensure that compression is maintained by F1 when pressure F2 is applied. As soon as a sufficiently large force F2 is exerted, the blocking position is released, whereupon the cover part 6 is released in the opening direction (marked by arrow -e) can be moved along the partition. This multi-stage opening process is difficult for children to understand. Tests have shown that the present box meets increased parental control requirements. Due to the still relatively simple handling, it is still designed seniors friendly.

FIG. 5 shows a portion of the blank for the box with the lid portions 13 and 14. At 12 a fold line is indicated, around which the two lid sections 13 and 14 can be folded and then glued together. The fold line 12 then becomes a folded edge, which forms a front, the insertion opening facing the end of the insertion tongue.

In the cover part section 14, a section for the latching lug is defined by a U-shaped cutting line and a weakening line. This section is in FIG. 5 for the sake of simplicity, designated 10. This section is folded down and glued to the lid portion portion 14. The folding creates a corresponding hole in the FIG. 6 denoted by 10 '. The FIGS. 5 and 6 continue to show the configuration of the arrangement for the exposure of the locking lug. For this purpose, two spacer segments 31 and 32 are provided, which are hingedly connected to each other via fold lines. The spacer segments 31 and 32 are folded upwards and glued to the lid part section 14. For better understanding, the distance segment labeled 31 is specially hatched.

FIG. 7 shows a cross section through the front portion of the cover part 6. For locking, the latch has a hook-like end 37. This is an edge formed by folding over the nose portion 10 and the web portion 34. Good recognizable is, for example, in consequence of folding the nose portion 29 created hole 29 '. In Figure 7a the locking connection between the locking lug 10 and one of the intermediate wall associated stop 38 can be seen. Evidently engages in the locking position, the hook-like stop facing the end 37 of the locking lug 10 latching in the stop 38 a. The corresponding counterpart, ie the mentioned stop 38, by a corresponding edge of the recess (11, see, eg

Fig. 2 ) formed in the intermediate wall 7. The locking lug 10 is received in the locking position in the complementary recess. Out Figure 7a then it is apparent that the two carrier sections 15 and 16 are not glued together in the area adjacent to the latching lug.

In the slightly schematic representation according to FIG. 8 can be seen how the exposure of the locking lug 10 is configured. Since between the web portion 34 and the upper lid portion 13, the two spacer segments 31 and 32 are arranged, the locking lug 10 is pressed relative to the plane of the lid part, as is apparent, down and held there.

FIG. 9 shows the lid part 6 in the locked position in the box. Evidently, the insertion tongue 8 is received in a receiving pocket similar gap 9. The intermediate wall 7 is formed in two layers, and forms in a non-bonded region the insertion opening 9 for sandwiching the insertion tongue 8 in the gap between the layers 15 and 16 of the intermediate wall 7. In the region of the insertion tabs 8, the layers 15 and 16 are not glued together.

FIG. 10 shows a blank 30 for the box. The rear side wall 4 and the front side wall 3 are connected to the two transverse side walls 5 via a respective hinge fold, which is folded inward when erecting the side wall portions. Still goes out FIG. 10 shows that the locking tongues are predetermined by approximately U-shaped cutting lines in the connecting web 26. By this configuration, the locking tongues during Aufrichtvorgang from the plane of the connecting web can be easily opened.

In FIG. 11 a blank 30 is shown, which is changed compared to that of the previous embodiment only in terms of the design of the locking means for the child safety. Evidently, the recess 11 and consequently also the complementary latching lug is significantly widened. This is achieved in that no web section is necessary for this packaging (cf. Fig. 10 : Bridge section 34). The blank 30 has a section 31 arranged in the cover section 14 and two sections 29 and 32 which are connected to one another via a fold line and which are assigned to the cover section 13. These three sections 29, 31, 32 form the latching nose after folding and gluing operations. FIG. 12 shows the individual sections after this processing step. The folded portion 31 forms a certain distance segment. The (not shown here) stop facing edge 37 for the actual form the folded portions 29 and 32nd
