Description
~001078 KWl00289/903.1.062 D 8436 FILM BAG-IN-BOX PACK
BACKGROUND
1.0 Field Of The Invention:
This invention relates generally to packs for material to be packed in a film bag, the film bag being accommodated in a folding box formed from a box blank, and more particularly to such packs including film bags with a capacity of 3 liters or more.
BACKGROUND
1.0 Field Of The Invention:
This invention relates generally to packs for material to be packed in a film bag, the film bag being accommodated in a folding box formed from a box blank, and more particularly to such packs including film bags with a capacity of 3 liters or more.
2.0 Discussion Of Related Art:
Bag-in-box packs of the field of the invention are used to accommodate liquids in varying amounts. Thus, such packs are known for packaging foods, more especially beverages, and also for dishwashing detergents, lubricants and the like.
These packs have the advantage that only the bag accommodating the material to be packed need be made of a high-quality plastics material, whereas the other parts of the pack, particularly those which absorb mechanical stressing, can be provided by an inexpensive carton of corrugated cardboard or the like. It is known in this connection that the closures can be left inside the carton during the transportation of such containers or may be supplied as separate elements to the consumer, who then has to fit them to the container for use or consumption of the packaged material.
.
.
, . : ' ' .
2001~8 Where packs of the type in question are used for relatively large quantities, for example for quantities of 5 to 10 liters, to carry wine for example, the pack carton has to have relatively high stability, which is normally achieved by making the pack of double-fluted corrugated cardboard. Such cardboard is unsuitable for high-quality printing, for example offset printing, with the result that goods of relatively high quality are not accepted by the consumer in packs of such inferior presentation. However, if such environment-friendly packs are to be brought to the attention of the consumer, they must be of high visual quality, easy to handle, must satisfy stability requirement, and so forth.

3.0 Summary Of The Invention:
With the problems of the prior art in mind, one object of the invention is to provide an improved bag-in-box pack.
Another object of the invention is to provide improved bag-in-box packs of relatively high volume that can be printed by high-quality printing, and remain sufficiently stable and easy to handle.
In one embodiment of the invention, these and other ob~ects are achieved in that, in addition to bottom flaps for forming an at least two-ply bottom, the box blank is equipped with head flaps for forming at least a two-ply head region.
Openings are punched in the head flaps to receive a pouring element on the film bag. Also, the side walls of the folding box in the in-use position are reinforced by an internally inserted reinforcing case of another carton blank.

200~)78 This embodiment of the invention enables the folding box blank to be formed externally from a comparatively thin carton or from thin corrugated cardboard, which can be printed with the usual high quality printing. The at least double-ply construction of the bottom and head regions provides for adequate stability, in substantially the same degree as the additional internal reinforcing case. The latter may be made, for example, of a low-quality carton or cardboard material.
Another embodiment of the invention is characterized in that a substantially U-shaped opening is punched into a first head flap part, positioned towards the interior of the pack in the closed position, from the free front edge for the insertion of a pouring or closure element on the folding bag. Openings are punched into the overlying head flap parts for the in-use position to allow this closure element to pass through in the in-use position. This enables the closure element on the film bag to be inserted into the U-shaped opening at the factory, and to be positioned beneath the other head flap parts during transportation and storage. Alternatively, it also enables the consumer, after opening the other head flap parts covering this head flap part, to insert a closure or pouring element accommodated inside the pack, and then to close the folding box again. The head flap parts are then folded over the pouring and closure element so that it is able to pass through the former.
In another embodiment of the invention, at least one other head flap part arranged over the bottom head flap part is equipped with a fixing flap, which is designed to be folded 2001t~8 back in the closed position. The free front edge thereof shuts, or closes off, the substantially U-shaped opening against the pull-out direction of the closure and pouring element after inser~ion thereof. It is thus possible with simple means to hold the closure and pouring element firmly in position by the correspondingly shaped fixing flap.
Another embodiment of the invention includes in the closed position, the openings in the head flaps where the closure and pouring element is accommodated, align at least locally with one another to form a three-ply wall region. This embodiment enables a multi-ply wall thickness to be obtained precisely in the relatively heavily stressed region, where the pouring or tap element is fixed in the in-use position.
In another embodiment of the invention, this element is made easier to insert by at least the opening in the bottom head flap part being provided with insertion chamfers.
A further embodiment of the invention is characterized in that the insertion chamfers are e~uipped with retaining lips, which secure the pouring or closure element at least locally in the in-use position. Accordingly, this head flap part engages behind the pouring or closure element, which is particularly appropriate where this fitting operation is carried out at the factory. The user then has merely to remove the pouring and closure element from the pack through the corresponding openings in the other head flap parts, optionally after tearing open corresponding parts of the pack, and to fix it in position, optionally by means of the fixing flap, to obtain a ready-to-use pack.

20~:~078 In another embodiment of the invention, the handling of screw closures or tap closures is facilitated by the fact that the substantially U shaped opening is provided with side edges extending substantially at a right-angles to one another. In other words, the opening may be square or rectangular.
Correspondingly shaped wall regions on the pouring and closure element may correspond to these three sides so that, during screwing, the closure element cannot be turned in the axial direction, instead it is held securely against rotation by the head flap parts.
Another embodiment of the invention is characterized in that at least one surface of the box blank, forming one side of the folding box, is provided with a substantially U-shaped opening with at least one double crease to form a handle. Via the reinforcement provided by the inner case, this embodiment further includes a corresponding opening punched in the opposite direction in the corresponding surface of the inner case.

DETAILED DESCRIPTION OF THE INVENTION
The blank of a folding box generally denoted by the reference 1 in Figure 1, includes carton surfaces separated lS from one another by creases or cut edges, namely the side walls 3 to 6 and bottom flaps 7 and 8 with corresponding gluing flaps 9, at least one side gluing flap 10 and the head flaps 11 to 14.
Provided inside the folding box 2 parallel to and adjoining the sides 3 to 6 is a reinforcing case generally denoted by the reference 15 in Figure 6, which can be glued via a gluing flap 16. Figure 7 is a simplified section showing the inner case lS in position in the folding box 2 and the position of the gluing flaps 10 and 16.
A film bag 17 is inserted into the folding box thus formed, reinforced by an inner case 15, in its in-use position, comprising a closure element generally denoted by the reference i .

~0~11D78 18. For positioning the closure system 18 and fixing it in the in-use position, the head flaps 11 to 14 are specially shaped, as will be explained in more detail below.
First, the right-hand head flap 11 in Figure 1 is kept comparatively short, and is followed by a head flap 12 of relatively large surface area of which the outer contours correspond to the overall surface of the folding box 2. A head flap 14 having substantially the same outer contours as the head flap 12 is shown on the left-hand outside. Arranged between the head flaps 12 and 14 is a relatively short head flap 13 into which, in accordance with one embodiment of the invention, a substantially U-shaped central opening 19 is punched with insertion chamfers 20 on both sides.
As indicated by a crease line, the head flap 13 is the furthest inside in the in-use position; above it lies the head flap 14 and then the head flap 12. In the embodiment illustrated in Figure 1, the three head flaps 12, 13 and 14 are glued to one another at the factory, whereas in the embodiment shown in Figure 4, the inner head flap 13b is only glued at its edge to the overlying head flap 14b. A multi-ply wall region is obtained in either case for receiving a closure or tap element 18.
The head flap 14 comprises an inner opening 21, while the head flap 12 has an inner, divided die-punched area comprising a relatively small flap 11 and a relatively large flap 23, which are designed to be partly torn out of the head flap 12 via die-punched bridges. The flap 22 can be completely removed, while the flap 23 can be hinged about a crease 24.
- ,. , - ' ' , , , ' ':
~00~78 To position the closure element 18 of the film bag 17 on the folding box 2, the closure element 18 is inserted into the opening 19, the chamfers 20 facilitating this insertion.
Corresponding shoulders or rings (which have not been denoted by reference numerals) on the closure 18 engage the head flap 13 at least locally underneath and on top. After the head flap 13 has been folded into the closed position, the head flap 11 can also be folded. The head flap 14 is then folded over, the opening 21 aligning at least locally with the opening 19.
To open the box, the flap 22 is removed from the head flap 12 and the flap 23 is turned upwards, for exposing thereunder the opening 19 in the head flap 13. ~he closure system 18 may then be lifted upwards and inserted. The closure system 18 so inserted may be fixed in position by turning the flap 23 downward again, because the flap 23 is provided with a front free edge 25 which shuts off the opening 19, for surrounding the closure system 18 on at least three sides, so that the closure system 18 can be fixed in position.
Figure 2 shows head flaps lla to 14a, which are substantially rectangular in their principal openings, with opening l9a enabling the closure system 18 to be inserted and secured against rotation.
By contrast, Figure 3 shows head flaps llb to 14b, and an opening l9b at the end of which are provided retaining lips 26 designed to engage locally behind the inserted closure system 18 to hold it in the in-use position, which particularly facilitates handling by the end user.
In addition to the described creases and openings in the . - .
... , . ~ : . ~.
Z0 [)1078 head flaps, the folding box blank 1 comprises another double-folded, substantially U-shaped opening 27 in a side wall (in this case side 6), which is used to form a handle.
Corresponding to the substantially U-shaped opening 27 with its double crease 28, another opening 29 with somewhat longer side edges is punched symmetrically in the inner case 15.
The mode of operation of the various flaps is shown in Figures 8 to 10. If a user presses on the flap 27 in the direction of the arrow 30 and hence on the inner flap 29, these parts of the carton turn inward as shown in Figure 9. The liquid in the film bag 17 generally accommodates such turning.
By folding about the double crease 28, the flap 27 can be turned to such an extent that it completely surrounds the inner case after the flap 29 has been turned back. The liquid in the pack then holds this region in the position shown in Figure 10, for forming a three-ply enclosed gripping edge. When the pack is full, the flap 29 on the inner case 15 can then turn back into the closed position shown in Figure 10 under the internal pressure of the product, so that the user can take hold here at any time to handle the folding box 2 and its contents. Through the die-punched side edges of the flap 29, the crease 31 is situated lower than the lower free edge of the flap 27, as shown in Figures 8 to 10, which both facilitates turning, and forming a stop for the flap 29.
The described embodiments of the invention have been given for purposes of illustration, and may be modified in many ways by those of skill in the art, without departing from the spirit and scope of the appended claims. For example, other .. ~
