Abstract

The present application describes a metering device which is characterised in that it consists a) of a metering chamber blank (2), which is attached to the folding-box blank (1) by the side parts (3, 8) at a predetermined point and which provides the metering chamber when the folding-box blank is erected by means of the predetermined folding lines (4, 6, 7), and b) of a scraping device (10) which is formed by the scraping edges (10a to 10c) when the folding box (1) is opened, the scraping edges (10a to 10c) resting closely against the cutting line (5) of the blank (2) in its end position. <IMAGE>

Dosing device

In the present application, a metering device is described, which is the Consumers enable predetermined quantities from a package to be easily and reliably refer to.

There have been a number of attempts to create such metering devices.

For example, U.S. Patent 3,187,961

such a metering device described. This dosing device is e.g. not for all packaging suitable. It is suitable for folding boxes that can be opened with pressure on the side even unusable— In addition, there are great difficulties with such fold-out dosing devices to put them back permanently in their original position.

The metering device described by US Pat. No. 1,679,237 is again suitable only for rigid containers and is also attached at a corner, which also has limited application possibilities allows. Here, too, the problem is the safe and easy reclosing of the Packing after removal of the bulk material. **

DAS 12 33 157 describes a container in which one of the end faces has a discharge opening is provided, which is formed by a hinged on the wall in question, designed as a measuring pocket Spout can be opened and closed, which is characterized in that a The wall part, punched out in the shape of a tongue, extends into the discharge opening from one edge thereof and the inner wall of "a rear wall i

and thereon bent side walls formed ι grommet and that the tongue with the grommet side walls is detachably connected and in the immediate vicinity of the rear wall and in a>

further, the measured amount determining angular position with respect to the rear wall of the spout and its side walls is detectable.

This dosing device is also only suitable for rigid containers, and that is again the case Reclosing problem.

The above-mentioned disadvantages are eliminated by the metering device discussed below. It enables multiple withdrawals of a predeterminable volume of pourable material, whereby the dosing accuracy is guaranteed by the proposed scraper edges (10). Simultaneously a suitable design of the stripping device ensures that the bulk material continues to flow during emptying the predetermined amount prevented.

The metering device according to the invention is suitable! for folding boxes that can be opened with side pressure,

especially for cases such as those described in German ■ Patent 12 18 339, namely those which tongue a extending on both sides of an upper side edge, i lines scribed boundary below the side edge provided closure \ have ', that a has crease line connecting upper and lower corners, the tongue being detachable from the box side wall in the area below the side edge by a pressure transversely to the crease line.

The dosing device according to the invention exists from a blank (2) made of foldable material, preferably cardboard, und'Abstreifkanten (10) according to the lines 10a to 10c (Figure I) of the folding box.

The blank (2) is preferably rectangular, with it on the side facing the pouring opening, starting from the side parts (3), in one of the stripping edge (10) adapted training (5) runs. The training (5) can be designed in a variety of geometric, predeterminable shapes e.g. as a triangle or trapezoid.

The blank (2) is pushed through the side parts (3.8) attached at a predetermined point on the folding box blank (1). Through the circumferential fold line (7) and the other folding lines (4, 6) are used when setting up the folding box blank (1) the dosing chamber for the bulk material is formed.

If the packaging is now tilted in the direction of the pouring device, the packaging according to the invention fills up Dosing chamber (11) when turning back. Protruding When the box, in particular a box, is subsequently opened, bulk goods are accordingly of German Patent 12 18 339, stripped by the scraper edge (10) and flows into the Pack back. A reflow of the bulk material

when emptying the metering chamber, this prevents the stripping edge (10) from being at the cutting line (5) of the pack when the pack is open
Cut (2) fits tightly. - i
