An economical and therefore environmentally friendly use of powdery chemicals, e.g. detergents * or the like, is required the most precise possible dosing of the materials, so only that much of which is consumed, as is absolutely necessary for the respective application. To this end has So far, for example, a measuring cup or the like has often been used, which is the packaging for the free-flowing product was enclosed as a separate part. The dosage by means of a measuring cup is very inaccurate connected, as the filling of the measuring cup up to the specified level depends largely on the person, who handles the measuring cup. Furthermore, the measuring cup can be used as a separate part from the container containing the filling material can easily be lost, whereupon can only be dosed by eye. Mechanically working dosing devices are also known in principle, but because of their complicated, expensive structure they are different from an extensive one Use in packaging.

In contrast, the invention is based on the object to create a container with a pouring opening for pourable contents that can be produced economically can and a dispensing of dosed product quantities with dispensed

Reaching accuracy made possible by a simple handling process.

According to the invention, this object is achieved by providing a metering space formed in the upper area of the container with one opening into the interior of the container Inlet and an outlet, and a collecting chamber which is substantially sealed off from the interior of the container is arranged in relation to the Dosiefraum and the pouring opening of the container so that in the substantially upright position of the container with the dosing space at the top, the filling material emerging from its outlet by gravity can be fed to the collecting chamber and in the substantially inverted position of the container with the bottom lying dosing space, the filling material located in the collecting chamber can be dispensed to the outside through the pouring opening.

The container according to the invention thus serves at the same time to receive the pourable filling material, e.g. a detergent Or the like., And for the delivery of the filling material in metered amounts each time the container from the upright position is moved into the inverted position and back. Any such Ilandhabungsvorgang leads to the product from the inside of the container reaches the dosing chamber by gravity and at the same time a dosed amount of filling material is discharged from the collecting chamber through the pouring opening of the container to the outside, while from the dosing chamber a predeterminable amount of e.g. 20, 40, 60 or more ml of filling material is returned to the collecting chamber in order to during the next cycle of movement over the pouring opening to be handed in outside.

The container including the one that accomplishes the dosing Facilities is preferably made by blow molding one suitable plastic material and therefore particularly economical Way made. The collecting chamber is the preferred catfish not an integral part of the container, but formed in a basket-shaped insert part, which is e.g. The pouring opening can be used in the container and there comes into sealing engagement with the seat surfaces ensure that the collecting chamber is largely sealed off from the interior of the container. The contents can therefore only reach the collecting chamber via the dosing chamber.

With regard to other developments of the invention, reference is made to the claims.

An embodiment of the invention is explained in more detail below with reference to the drawing. The drawing shows one Container constructed according to the invention in the central longitudinal section in the upright position. The following used Terms "top", "bottom", "right" and "left" relate to the position shown in the drawing Container.

The container of the preferred embodiment has a generally rectangular outline configuration with a front and rear wall 1, 1 · (only the rear wall 1 is shown in the drawing), a right and a left / ,. Side wall 2, 2 · and a bottom wall 3. It goes without saying however, that the invention is not limited to the shown oversized configuration of the container, but rather the container can basically be designed in any way and e.g. have a round, oval or other type of oversized configuration can.

The horizontal wall section 5, the downwardly projecting wall section 6, the upper area of the right side wall 2 and the relevant sections of the front and rear walls 1, 1 'together delimit a space 4 at the top, which is referred to below as the dosing space. The metering space has an inlet 7 and an outlet 8 which are defined by the upper end edge 10 of a partition 9 which extends between the rear and front walls 1, 1 x of the container. In the embodiment shown, the upper end edge 10 of the partition 9 lies in a substantially horizontal plane which passes through the lower end of the downwardly projecting wall section 6, and the inlet 7 of the metering chamber 4 has a substantially the same cross-sectional area as the outlet 8. However, the invention is not limited to such a dimensioning and location of the inlet and outlet 7, 8 of the metering chamber 4. The upper end edge 10 of the partition wall 9 can also be arranged further inside the doeierraumes 4 or close below it

be. Due to the described conditions, the inlet 7 and the outlet 8 of the metering chamber 4 both basically open downwards towards the bottom wall 3 of the container

The partition wall 9, which provides the upper end edge 10, extends at a suitable angle of inclination from top right to bottom left and thus forms a slide or sliding surface in the container / along the one from outlet 8 escaping product can slide.

The partition wall 9 ends at a lower end face 11 and extends at a distance from the aforementioned inclined wall portion 12 of the upper end wall of the container, so that between the oblique. Wall section 12 and the partition wall a Passage 15 is formed for the filling material emerging from the outlet 8 of the dosing chamber 4.

At a suitable position, e.g. on the left-hand side of the container, an upwardly projecting ring-shaped one can be placed on its upper end wall Wall area or mouth neck 13 may be formed which defines the pouring opening of the container. On the outside Perimeter of the annular wall portion or mouth neck 13 of the container can be threaded to a Cap 30 for closing the pouring opening on the neck of the mouth to be able to unscrew.

According to the invention is through the pouring opening of the container Insert part used, which bears the general reference number. The insert 20 creates a collection chamber in the container 16, which is only connected to the interior of the container via the passage 15 and the metering chamber 4. the Collection chamber 16 is formed by a lower, substantially cup-shaped wall region of the insert part 20, which a preferably slightly tapered from top to bottom circumference β wall 24 and a bottom wall 25 comprises. 0'er

Product on the left side of the container when it is around E.g. turned 180 ° downwards.

For easier handling of the container, a hand hole 19 can be provided in a manner known per se, which extends between the front and rear walls I, 1 '.

With the exception of the insert 20, the container constructed as described above can be made by blow molding a suitable one Plastic material are produced. The insert part is preferably a plastic produced by injection molding part.

When the container is filled with a pourable product, e.g. a washing powder, the pouring opening of the Container used the insert 20 to provide the sealed against the container interior collection chamber 16. If the container is then from the upright position shown in the drawing by hand with the aid of the Hand holes 19 turned down, se that the metering chamber 4 below and the bottom wall 3 come to lie above, moves the free-flowing product inside the container through the inlet 7 into the dosing chamber 4. Then the container is again rotated into the upright position shown, so a part of the filling material located in the dosing chamber 4 falls through the Inlet 7 back into the interior of the container and another part through the outlet 8 onto the partition 9. Along the partition 9 the filling material slides into the collecting chamber 16 of the insert 20. A certain amount therefore collects in the collecting chamber 16 Amount of filling material that will pass through the pouring opening the next time the container is turned into the downwardly rotated position is dispensed when the cap ZO has been removed from the neck of the container.

It suffered

Any tilting or rotating movement of the container from the upright to the inverted position and back will therefore released a certain amount of filling material. The dispensed product quantity essentially corresponds to the product « that see above the outlet 8 accumulates in the metering space 4 during the time when the container is in the downward direction rotated position. For the person skilled in the art, it is understood that further items are needed to estimate the quantity of filling material dispensed Factors such as its pourability and the like are taken into account Need to become.

Although the invention has been described on the basis of the dosing of pourable filling material, it is a container according to the invention basically also for dosing liquid products suitable. In the embodiment shown, the metering space is essentially through the outer walls of the Container formed. It goes without saying, however, that the metering space can also be separated in the container, e.g. in the form of an insert similar to the insert 20 could be provided. Furthermore, the inlet 7 and the outlet 8 of the metering chamber 4, unlike the embodiment shown, also on different levels are essentially parallel to the bottom wall 3 of the container.
