DESCRIPTION:
BRIEF SUMMARY
This invention relates to a cardboard packaging which is used for liquids and consists of a folding box, an inner container arranged therein and made from a plastic material, and of a withdrawal nozzle which is accessible from the outside through a hole formed in one wall of the folding box. Such a cardboard packaging is e.g. known from German patent application 38 02 793.
Packagings of this type are used as nonreturnable packagings and intended as a substitute for bottles or containers made of plastics, glass or sheet metal. Their main purpose consists in facilitating their disposal after use. The folding box guarantees the necessary stability, while the inner container ensures a tight sealing of the liquid contained therein.
As for the packaging known from the above-mentioned publication, the inner container consists of a flexible plastic bag which after production must be inserted into the erected folding carton. The delivery of the packaging in the finished state to the filling company necessitates the transportation of empty containers having a relatively large volume, which is not economical. However, when the individual parts thereof are sent separately--the outer carton may here be in a flat state, the inner container must first be inserted by the filling company into the folding box to be erected at the filling plant. Difficulties arising therefrom consist in that when the inner container is introduced into the folding box, the air contained in this box must be removed. Moreover, the withdrawal nozzle must be suitably positioned on the folding box in such a way that it does not rotate during opening or closing if it is not held by hand during these operations. As a result, the packaging is relatively difficult to handle and uneconomic on the whole.
It is the object of the present invention to provide a cardboard packaging of the above-mentioned type which can be produced easily and handled in a space-saving way up to the filling operation and, nevertheless, has the advantage that the inner container can collapse in the folding carton during emptying so as to prevent the contents thereof from coming into contact with air prior to withdrawal, and it should here not be necessary to hold the withdrawal nozzle separately during the screwing or unscrewing of a screw cap or a withdrawal fitting.
The invention, its features and advantages, as well as the method of making and handling the cardboard packaging in the production and filling processes shall now be explained in greater detail with reference to an embodiment illustrated in the drawings, in which
FIG. 1 shows a developed blank as a part of the cardboard packaging;
FIG. 2 a perspective view of the cardboard packaging with an inner bag disposed therein, in the partly closed state of the folding carton;
FIG. 3 a detail of a vertical section through the packaging of FIG. 2--approximately actual size; and
FIG. 4 a developed blank of a cardboard packaging in accordance with a simplified embodiment of the invention.
As shown in FIG. 1, the blank for the packaging of FIG. 2 substantially consists of four sections 1, 2, 3 and 4 arranged one after the other in the direction of arrow A, and of an adhesive tab 5 bordering on one end thereof, with the individual members being separated from one another by transversely extending folding lines 6, 7, 8 and 9. In the erected state of the folding box said four sections 1-4 form four complete walls of the box. One of the sections--in the present case section 2--has a circular hole through which a withdrawal nozzle can enter.
Two sections that are not adjacent--in the illustrated embodiment sections 2 and 4--are continued by lateral flaps 11a and 11b, respectively, which have a width measured in a direction transverse to the direction of arrow A, i.e. in the direction of arrow B, which is at the most half as great as the length of section 1 and 3, respectively, measured in the direction of arrow A. In the direction of arrow A flaps 11a have substantially the same dimensions as section 4, on which they are mounted, w
