DESCRIPTION:
BRIEF SUMMARY
The invention relates to a pack container with an internal bag for receiving fluids, formed from an elongated blank pre-glued along its short side to form a folded carton shell which is uprighted from a collapsed condition to form a tubular body having a rectangular cross-section and featuring a plurality of flaps which by folding and glueing to each other convert the tubular body into a closed elongated folded carton essentially cuboid in shape and featuring two large main panels parallel to each other, connected together by side surface areas extending vertically from the former, together with a liquid-tight tube of a plastic film arranged in said carton shell and featuring a weld running at a right angle to the elongation of the blank, the ends of which are closed off by welds running in the direction of the elongation of the blank.
One such pack container has already been put on the market by the Applicant.
Containers of the above kind serve to package liquids as a replacement for collations of plastic or tin. A pack container of this kind can be fed to a packaging machine preglued as a collapsed folded carton in which a plastic tube is inserted. The packaging machine uprights the collapsed folded carton, seals the plastic tube contained therein and closes the carton by folding and glueing its flaps in place.
The container is filled before the plastic tube is sealed and the folded carton shell is closed or--when a closure sleeve is provided prior to the plastic tube being sealed--after the plastic tube is sealed and after closing the folded carton shell by the closure sleeve.
The advantage of folded cartons having an internal bag is that they require very much less plastic material for receiving a given quantity of fluid than a plastic bottle of corresponding filling volume and that they can be collapsed together very easily after use, thus making their disposal considerably more facilitated than that of plastic bottles or tin cans.
With domestic detergents there is now a trend towards liquid concentrates which are replacing more and more the earlier conventional washing powders.
Due to the mass consumption of these products there is a requirement for a suitable and, in particular, environmentally-compatible package especially since in this sector, package recycling has been unable to become established as compared to that of the beverages sector.
The object of the invention is to create a paper pack container having an internal bag for receiving fluids of the type as aforementioned which has the external appearance of a bottle and which can be easily manufactured, filled and emptied.
This object is attained by a pack container having the characteristics defined in the opening paragraph of the specification, wherein its neighbouring longitudinal sides to roughly half of the amount of elongation, forming a trapezoidal profile in this region, folded vertical to the main surface areas, areas lower side flaps are provided, folded vertical to the main surface areas and glued to each other.
On at least one of the lowerside flaps a cover flap is provided which is located on the upperside flaps, and on the head panel shortened by the slanting of the main panels, flaps are provided located over at least a part of the cover flaps.
The invention relates to a pack container which stands upright more or less in the form of a bottle and in which normally liquid washing concentrates are sold. Bottles of this type generally feature a slim shape having substantially an oval or rectangular cross-section which tapers towards the top. Slanting at least one of the longitudinal edges of the main panels of the pack container clearly defines the "top" and "bottom" of the container, it approximating the shape of a usual washing concentrate bottle to favourably influence the decision to buy of the consumer.
The invention makes it possible to provide the blanks in thru-production with the internal bag material which is produced from a flat web of plastic film (foil) since the weld for forming a tube from the film web runs in the
