Abstract

Pour un emballage destiné à un produit devant être emballé dans un sachet en feuille plastique placé lui-même dans une boîte pliante réalisée dans une découpe, en particulier pour les sachets d'une contenance de 3 litres et plus, il convient de trouver une solution avec lequelle il serait possible d'avoir une excellente qualité d'impression tout en conservant une stabilité suffisante et en assurant une bonne maniabilité et ce, précisément dans le cas de emballages relativement volumineux du type ''carton-outre''. Dans ce but, la boîte pliante découpée (1) comporte, outre des fonds pliants (7, 8) permettant de constituer un fond avec au moins une double épaisseur, des parties supérieures pliantes (12, 14) permettant de constituer une partie supérieure également avec une double épaisseur au moins, ces parties supérieures pliantes (12, 14) comportant des évidements (19, 21-23) pouvant recevoir un élément verseur (18) du sachet (17) et les côtés (3, 6) de la boîte pliante (2) sont renforcés, en position d'utilisation, par un cadre (15) disposé à l'intérieur et réalisé également dans une découpe en carton.For a packaging intended for a product to be packaged in a plastic foil sachet placed itself in a folding box made in a cutout, in particular for sachets with a capacity of 3 liters and more, a solution should be found with which it would be possible to have an excellent printing quality while retaining sufficient stability and ensuring good handling, and this, precisely in the case of relatively bulky packaging of the "cardboard-addition" type. For this purpose, the cut-out folding box (1) comprises, in addition to folding bottoms (7, 8) making it possible to constitute a bottom with at least a double thickness, folding upper parts (12, 14) making it possible to constitute an upper part also with at least a double thickness, these folding upper parts (12, 14) comprising recesses (19, 21-23) capable of receiving a pouring element (18) of the bag (17) and the sides (3, 6) of the box folding (2) are reinforced, in the position of use, by a frame (15) arranged inside and also made in a cardboard cutout.

"Packaging for goods to be packed in a foil bag"

The invention relates to packaging for goods to be packaged in a film bag, the film bag being accommodated in a folding box formed from a blank, in particular for film bags of 3 liters and more.

Such so-called "bag in box packaging" serve to hold liquids in different quantities. Packaging of this type is known for food, in particular drinks, but also for detergents, lubricants and the like. These packaging have the advantage that only the receiving bag for the goods to be packaged has to be made from high-quality plastic material, while the others, in particular Further packaging parts that absorb mechanical loads can be picked up from an inexpensive corrugated cardboard box or the like. It is known to leave the closures in the interior of the cartons during the transport of such containers or to provide them as separate elements to the consumer, who must then attach them when in use.

With such packaging for larger quantities, such as for quantities of 5 and 10 liters, such as for wine already are known, comparatively large stabilities of the packaging boxes are necessary, which is usually ensured by packaging in corrugated cardboard. Such cardboard is particularly unsuitable for high-quality printing, for example in offset printing, which means that higher-quality goods are not accepted by the consumer in packaging with such an inferior design. However, in order to introduce consumers to such environmentally friendly packaging, they must be of optically high quality, they must meet the stability requirements, they must be easy to handle and the like.

The object of the invention is therefore to create a solution with which high-quality printing is possible, especially in the case of larger-volume so-called "bag in box packaging", as well as maintaining sufficient stability and ensuring easy handling.

This object is achieved according to the invention in that the folding box blank is equipped, in addition to bottom flaps for forming an at least double-layer bottom, with top flaps for forming an at least double-layer head region, punchings being provided in the top flaps for receiving a pouring element on the film bag and that the side walls of the folding box in the use position with an internal reinforcement frame are reinforced from another cardboard blank.

This embodiment of the invention makes it possible to form the folding box blank on the outside from a comparatively thin cardboard or from thin corrugated cardboard, which can thus be printed with the usual high quality, the at least double-layer design of the bottom and head area also ensures sufficient Stability like the additional internal reinforcement frame, which can be made, for example, from an inferior cardboard or cardboard material.

One of the possible configurations of the invention is that a first head flap part positioned in the closed position towards the inside is provided with an approximately U-shaped punched-out area from the free front edge for inserting a pouring and closing element on the folding bag, the ones lying above in the use position Head flap parts are provided with punched-out sections which, in the position of use, allow this closure element to pass through.

Such a design makes it possible either to insert the closure element on the film bag into the U-shaped punching at the factory and to position it under the other head flap parts during transport and storage, but it also gives in in the same way the consumer has the possibility, after opening the other head flap parts covering this head flap part, to insert a closure and pouring element accommodated in the interior of the packaging, in order to then close the folding box again, the head flap parts then being closed by means of the Pouring and closure element are placed so that it can pass through there. •

An embodiment of the invention consists in that at least one further head flap part arranged above the lower flap part is equipped with a fixing flap which can be folded back in the closed position, the free front edge of which is the substantially U-shaped punching after insertion of the fastener - and pouring element blocks or closes against the direction of extension of this element. This makes it possible with simple means to lock the closure and pouring element without displacement with the appropriately designed fixing tab.

In a further embodiment, the invention provides that, in the closed position, the punched-out portions in the head flaps (12, 13 and 14) in the receiving area of the closed and pouring element (18) form at least one three-layer wall area (FIG. 5) areas in some areas. With this design, it is possible to achieve a multi-layer wall thickness, particularly in the more heavily loaded area in which the pouring or urine element is fixed in the position of use.

To make it easier to insert this element, the invention also provides that at least the shape in the head flap part below is equipped with insertion bevels.

In a further configuration, the invention also provides that the insertion bevels are equipped with clamping lugs that at least partially secure the lug element in the position of use. Thus, this head flap part snaps behind the pouring or closing element, which is particularly useful if this introduction is made at the factory. The user then only has to pull the pouring and closing element out of the packaging through the corresponding recesses in the further head strap parts and, if necessary, lock it in place by means of the locking tab, in order to obtain a ready-to-use packaging to obtain.

In order to facilitate the handling of screw closures or cock closures, the invention provides in a configuration that the essentially U-shaped punched-out area

REPLACEMENT LEAF is provided with side edges running essentially at right angles to one another, in other words the punched-out area can be square or rectangular. Correspondingly designed wall areas on the pouring or closing element can then correspond with these three connections, so that when screwing it is no longer possible to twist in the axial direction of the closing element, rather the latter is held against rotation by the head flap parts.

The invention also provides that - at least one surface of the blank forming one side of the folding box is equipped with an essentially U-shaped punching with at least one double crease line to form a handle, whereby, because of the reinforcement by the Inner frame, the invention also provides that a corresponding punch is provided on the corresponding surface of this inner frame, the punching being opposite.

The invention is explained in more detail below with reference to the drawing, for example. This shows in

1 shows the cutting of a folding box of the packaging according to the invention, 2 and 3 modified embodiments of the design of the head flaps,

4 shows a section of a package in section with an internal closure system,

5 shows a partial cross section corresponding to the illustration according to FIG. 4 with the closure system in the pouring position,

6 shows a frame cut in a simplified representation,

7 shows a cross section through the packaging of the inner frame and in the FIGS

8 to 10 different folding positions of a handle in the packaging wall with an inner frame.

The blank of a folding box 2, generally designated 1 in FIG. 1, consists of cardboard surfaces separated from one another by embossing lines or cutting edges, namely the side walls 3 to 6 and bottom flaps 7 and 8 with corresponding adhesive flaps 9 and at least one side adhesive flap 10 and the head flaps 11 to 14.

REPLACEMENT LEAF In the interior of a folding box 2 of this type, a reinforcing frame is provided parallel and adjacent to the sides 3 to 6, which is generally designated 15 in FIG. 6 and can be glued via an adhesive flap 16. 7 shows a sectional drawing with the inner frame 15 inserted into one another in the folding box 2 in a simplified representation with the position of the adhesive layers 10 and 16.

In the use position, a film bag 17 with a closure element, generally designated 18, is inserted into a folding box formed in this way and reinforced with an inner frame 15, the special design of which is not important here.

In order to be able to position the locking system 18 and to be able to fix it in the assembly position, the head flaps 11 to 14 are specially designed, which is described in more detail below.

First, the right-hand head flap 11 in FIG. 1 is kept comparatively short, followed by a large-area head flap 12 which corresponds in its outer contours to the total surface of the folding box 2. A head flap 14 is shown on the left outside, which likewise has essentially the same outer contours as the head flap 12. Between the head flaps 12 and 14 there is a head flap 13 which is shorter and, for the fertilizer essential, a middle approximately U-shaped punched 19 has with threading bevels 20 on both sides.

As indicated by a creasing or embossing line, the head flap 13 lies furthest inside in the position of use, above it the head flap 14 and subsequently the head flap 12. The three head flaps 12 are factory-set in the exemplary embodiment according to FIG. 13 and 14 are glued to one another, while in the exemplary embodiment according to FIG. 4 the inner head flap 13b is only glued at the edge to the head flap 14b lying thereover. In any case, this results in a multi-layer wall area for receiving a closure or tap element 18.

The head flap 14 has an inner punching 21, while the head flap 12 has an inner, two-part punching flat, namely a smaller area 22 and a larger area 23, which can be partially torn out of the head flap 12 via punching bridges Are formed, the surface 22 can be completely removed, while the partial surface 23 is pivotable about a crease line 24.

When the closure element 18 of the film bag 17 is positioned on the folding box 2, the closure element 18 is pushed into the recess 19, the bevels 20 facilitating the insertion. Corresponding, unspecified shoulders or rings on the closure

REPLACEMENT LEAF 18 then under and overlap the head flap 13 at least in regions. After swiveling the head flap 13 into the closed position, the head flap 11 can also be swiveled in. Now the head flap 14 is folded over, the punched area 21 is then flush with the punched area 19 in some areas.

To open the box, the partial area 22 in the head flap 12 is removed and the partial area 23 is pivoted upward in such a way that the shape is then underneath

19 is exposed on the head flap 13. Now the locking system can be lifted up and pushed in. By pivoting the partial surface 23, the now threaded closure system 18 can be locked, since the flap 23 is equipped with a front free edge 25, which then blocks the shape 19, which essentially encloses the closure system 18 on at least three sides, in such a way that the Locking system can be fixed.

Head flaps 11a to 14a are shown in FIG. 2, which are essentially rectangular in shape in their essential forms 19a in order to enable the locking system 18 to be inserted in a manner that prevents rotation.

3, on the other hand, shows a punched-out portion 19b, at the free ends of which locking lugs 26 are provided, which

ATZBL as the inserted locking system 18 can reach behind in order to fix it there during assembly, which in particular facilitates handling by end users.

In addition to the creasing lines and punched-outs in the head flaps described, the folding box blank 1 also has a further double-folded, approximately U-shaped punched-out punch 27 in a side wall, here page 6, which is used to form a carrying handle. Corresponding to the approximately U-shaped punch 27, which has a double crease line 28, a further punch 29 punched symmetrically in relation to the envelope is provided in the frame 15 with somewhat longer lateral punched edges.

The mode of operation of these punched-outs is shown in FIGS. 8 to 10. If the consumer presses in the direction of arrow 30 on the punched-out 27 and thus also on the inside punched-out 29, these cardboard areas pivot in the manner shown in FIG. 9. The liquid in the film bag 17 generally permits such pivoting. By turning the punch 17 around the double crease line 28, the latter can be pivoted so far that it completely surrounds the inner frame after the punch 29 has been swung away, the liquid in the packaging then holds this area in the position shown in FIG. 10 such that

TZBLA there is a three-layer enclosed grip edge. The punched-out 29 on the inner frame 15 can then pivot back into the closed position shown in FIG. 10 in the case of full packaging due to the product internal pressure, the user can now intervene here at any time to handle the folding box 2 with its contents. Due to the lateral punched edges of the punched-out 29, the groove 31, as can be seen in FIGS. 8-10, lies deeper than the lower free edge of the punched-out 27, which serves both for easier pivoting and for forming a stop for the die cut 29.

Of course, the described embodiment of the invention can be modified in many ways without departing from the basic idea. In this way, further configurations of the head flaps can also be provided. Instead of a single-layer inner frame, a double-layer inner frame and the like can also be provided.
