Definitions

  • This invention relates to a so-called bag-in-box which comprises a rigid outer container made of cardboard or the like,an inside flexible container made of plastic or another flexible, liquid-impervious material and a dispensing device sealed to the flexible inner bag and which is to be stabilized on an opening in the outer rigid container once the product packed in the package is to be dispensed. More particularly,the invention consists in new and useful improvements of such a bag-in-box, involving optimum use of its volume be it for shipping or storage, convenient access to its contents little by little, and disposing of the empty package in a way suitable for possible recycling.
  • the dispensing device attached to the inner bag is most frequently stored inside the rigid outer container until the time the contents is to be first delivered. At that time, the outer rigid container has to be opened to a certain extent and the dispensing device has to be found and pulled outwardly to be stabilized in the appropriate way.
  • German patent 1 486 558 filed November 28, 1963, describes a bag-in-box whereby the pouring spout, attached to the inner bag, is located inside the outer rigid container during shipping and during storage, and does not have to be taken out of the outer rigid container through an ad hoc opening but is reachable by breaking away a part of the outer rigid container when the product is first to be dispensed. Assembling and closing such a container on an automated line is not easy in that this cannot be achieved by using one single cardboard blank, but an additional piece of material is necessary to keep the dispensing tap which is attached to the flexible inner container, in the proper location so that it coincides with the part to be broken away from the outer rigid container.
  • breaking away such a part is not a simple operation eiter since, if the container is to be strong enough for a possibly heavy contents, an instrument like a knife may be needed to break away this removable part in order to avoid damage to fingers or finger-nails. Finally, if the individual components of the total package have to be separated for disposal and, possibly, recycling, the user is to study carefully the combination of flexible inside container and outer rigid container in order to get the individual elements untangled and separated.
  • the problem this patent application addresses is easy checking of the sealed cover of the pouring spout, without damage to the outer carton.
  • the positioning of the pouring spout is partly set thanks to an additional piece of cardboard and is furthermore regulated by the positioning of the complete bag-in-box, the weight of the contents pushing the spout either toward an opening in the rigid outer container or again down inside the outer rigid container if the package is tilted in a different direction.
  • U.S. Patent 4,572,422 describes another solution for optimizing use of volume while keeping the spout reasonably protected during shipping and storage. This is achieved by providing the final package with a slanted cut-off corner, through which the spout protrudes, a possibility existing for extracting the spout even further through the panel of that slanted corner. It will be evident that, by having the spout stick out of the outer rigid container also shipping and storage, additional reinforcement or protection will be needed to stabilize it in that area, possibly by providing additional layers of material or additional glueing points. Furthermore, the package according to U.S. Patent 4,572,422 does not provide space for holding e.g. a dosing device consequently no corresponding access opening.
  • German Patent Application DE 38 06 730 A package combining a bag-in-box providing space for the dosing device and protection for the pouring spout until first use, in addition with an easily shape, is described in German Patent Application DE 38 06 730.
  • this patent application describes a feature which, at the time of shipping, is integral with the outer rigid container and which, at the time of first use, can be partially detached and folded over to serve as a basis with inclined surface to enhance complete emptying of the package.
  • the package is not only expensive to automate on the packing line, five blanks having to be assembled in addition to the insertion of the flexible inside container holding the product and the dispensing device.
  • no optimal use of the total volume is made, as can be easily seen from the drawings.
  • the present invention provides a bag-in-box comprising an outer rigid container, an inner flexible container equipped with a dispensing device, said device being located inside the outer rigid container during shipping and storage, and means for giving quick and easy access to the dispensing device when it is to be put in place and stabilized for first dispensing of the contents.
  • the bag-in-box according to the invention is so sized and the means for getting access to the interior is sized and so positioned that a dosing device or another object like a premium can be held inside the outer rigid container for shipping and for storage, while these can be easily removed after operation of said opening means, the rigid outer container being easily reclosable around said dispensing device.
  • the blank out of which the rigid outer container (1) is formed consists of side panels (2,3,4,5 and 6); of bottom panel flaps (7,8,9 and 10); and of top panel flaps (11,12,13 and 14) flaps 11 and 13 each consisting in fact of two sections, respectively 11a and 11b and 13a and 13b.
  • Side panel (2) shows a handle opening (15) whereas side panel (6) shows a partially pre-cut and partially pre-scored handle opening (16).
  • Top panel flaps (11 and 13) show symmetrical cut-outs (17 and 18) between the two sections and symmetrical double score-lines (19 and 20).
  • Top panel flap (12) shows pre-scored tear-strip (21) and pre-scored tap opening (22).
  • Top panel flap (14) shows a cut-out (23) of a diameter which is slightly larger than that of the pre-scored tap opening (22) of top flap (12).
  • Top panel flap sections (11b and 13b) are divided along their respective edges touching top panel (12) by a score line only, so that they remain integral with said top panel (12).
  • Fig. 2 shows how the carton blank of fig. 1 is partially erected, the top panel remaining open.
  • This partial erection is performed in a way well known to the man of the art, i. e. a rectangular tube is formed by folding the side panels (2,3,4,5 and 6), side panel (6) coming to rest over and being glued on the outside of side panel (2), opening (15) and partially pre-cut/partially pre-scored temporarily blocked handle opening (16) coinciding with each other.
  • bottom panel flaps (8 and 10) are folded inwardly by 90° and, as a next step, bottom panel flaps (7 and 9) are also folded towards each other by 90° and glued onto previously folded over bottom panel flaps (8 and 10).
  • top panel flaps out of which the top panel will be formed are still open and the flexible inner container (24) which has already been formed and filled in a conventional way with product (25) is being dropped into the partially erected rigid outer container (1).
  • Flexible inner container (24) is provided with dispensing tap (26).
  • the flexible inner container not being completely filled, its shape will easily adjust to the shape of the rigid outer container.
  • dosing device (28) will be dropped in the rigid outer container to come to rest on top of flexible inner container (24).
  • top panel flaps (11, 12, 13 and 14).
  • sections (11a and 13a) of the corresponding top panel flaps are folded inwardly by 90° at the point of cut-outs (17 and 18).
  • top panel flap (14) is folded inwardly to come to rest on top of and being glued to said inwardly folded sections (11a and 13a).
  • Cut-out (23) coinciding with part of the cut-outs (17 and 18) this will leave a slot (29) into which the dispensing tap (26) can be inserted and stabilized once it is put in place for dispensing.
  • top panel flap (12) is bent over to come to lay on top of the already bent over top panel flaps, and top panel section (12b) is being glued onto the coinciding area of the outer surface of top panel flap (14).
  • FIG. 4 The perspective view of fig. 4 shows the bag-in-box erected and closed as made from the cardboard blank shown in fig. 1, with side panels (5 and 6) and top flap (12) with pre-scored zip tape (21) and pre-cut tap opening (22) for dispensing tap (26) visible.
  • Fig. 6 shows how part (12a) of top panel flap (12) flips open automatically upon removal of tear strip (21), thereby freeing an opening giving easy access to the dosing device (28) and the flexible inner container (24) with tap (26).
  • Part (12b) of top panel flap (12) remains attached to the outer surface of top panel flaps (14), thereby giving additional strength to the tape stabilizing slot (29), whereas, thanks to symmetrical cut-outs (17 and 18), parts (11b and 13b) can flip up together with top panel flap part (12a) to which they remain attached.
  • Fig. 7 shows how, after dosing device (28) has been removed, dispensing tap (26) is stabilized in slot (29), flexible inner container (24) remaining inside the rigid outer container (1).
  • fig. 8 illustrates how top flap panel part (12a) is bent over and slit around the basis of dispensing tap (26), thereby stabilizing it further and also reclosing the top panel of rigid outer container (1).
  • FIG. 9 illustrates how, by superimposing and glueing together side panels (2 and 6), making handle opening (15) and partially precut and partially pre-scored handle opening (16) coincide, a convenient carrying device which can at the same time act as pilfer-proof device against removal of e.g. premiums from the rigid outer container, is obtained.
  • the hand is pushed inside partially pre-cut and partially pre-scored temporarily blocked handle opening (16)
  • the corresponding part (16a) is pushed inwardly and folded back by 180° along the partially pre-scored line (16b), thereby traversing handle opening (15) and coming to lay against the inside of side panel (2).
  • a strong carrying handle is formed, but a protection against hurting the fingers by raw edges is provided.
  • the cardboard blank (101) represented in fig. 10 differs from the cardboard blank presented in fig. 1 in that the handle opening has been provided in a different location.
  • the carrying device 16 is provided in the double wall formed by side panels 2 and 6, which double wall lays close to the final stabilization position of dispensing tap 26,
  • the handle opening 116 of the cardboard blank according to fig. 10 is provided in the double wall formed by side panels 4 and 2, which leads to having the handle opening located on the panel opposite the panel closest to the dispensing tap when stabilized in its dispensing position.
  • top flap panel (12) flip back by liberating it from around dispensing tap (26), disengage dispensing tap (26) from slot (29) and pull the empty flexible container from the rigid outer container.
  • This empty flexible container can then go for recycling to the plastics collector, whereas the rigid outer container, normally made of a cardboard type material, can go to the paper collector.
  • Suitable materials for making the rigid outer container are cardboard, cardboard laminate, whereas suitable materials for making the inner flexible container are polyethylene or a nylon sandwiched between two layers of polyethylene.
  • these materials are not limiting and their choice will be influenced by the type of product to be held in the container, its use not being limited to liquid detergents.
