Device for Storage Tanks Producing Combined Packages
The invention relates to a device for storage containers for forming combined packs and to the combined pack itself.
The invention relates to a device for storage containers for forming combined packs and to the combined pack itself.
A wide variety of different forms of storage container are known. Crop protection agents are often packed in storage containers. Crop protection agents may be mixtures containing a number of active ingredients. In order to allow a number of combinations of active ingredients, the crop protection agents are filled into individual storage containers and then loosely combined in outer packaging, e.g. in a folding box or packing case, to form a combined pack.
Single-part double-chamber canisters are known from the prior art. The disadvantage with these canisters, however, is that more packaging material is needed to produce them than is the case for two individual canisters. In addition, the choice of materials is restricted for such canisters. Moreover, special machines are required in order to fill crop protection agents into such double-chamber canisters. A further disadvantage of these canisters is that they do not allow flexible filling of the individual chambers.
The object of the present invention is to provide a device which allows the fixed connection of a plurality of storage containers in the handle region, this resulting in the formation of a combined pack which cuts back on packaging and is easy to transport and carry. Furthermore, it is also intended for it to be possible for all the storage containers to be emptied simultaneously or in succession. In addition, the device is intended to ensure a more flexible choice of materials.
This object is achieved by the device according to the invention in that a connector is pushed through the handles of the storage containers and two or more storage containers are fixedly connected by virtue of at least one closure being plugged on.
One advantage of this plug-in device is the straightforward connection, which cuts back on packaging, of two or more storage containers in the handle region, thus providing for carrying capability and allowing the storage containers to be emptied simultaneously. It is also advantageous that the storage containers can be filled independently of one another and, following filling, can be combined as desired by the plug-in device.
An advantageous configuration provides for storage containers with different filling volumes to be connected. A stand is used for this purpose. This stand also serves for transporting the combined packaging unit on the filling line during labeling or simultaneous filling.
The plug-in device may advantageously consist of plastic, and is then preferably produced by injection molding. As an alternative, provision may also be made for the plug-in device to consist of other packaging materials, e.g. cardboard.
In a further embodiment, the connector can be connected to the closure by a screw thread.
The storage container may likewise advantageously consist of plastic, and is then advantageously produced by blow molding. As an alternative, it is also possible for the storage container to consist of other packaging materials.
The plug-in device of the type described above is suitable, in particular, for packaging two different products in a combined pack. Such a combined pack is suitable, in particular, for packaging and transporting pourable materials. Possible pourable materials are constituted by solid and liquid materials. These include, preferably and by way of example, solid crop protection agents, in particular the granules thereof.
The invention likewise relates to the combined pack which is formed by means of the plug-in device.
The invention is explained in more detail, by way of example, hereinbelow with reference to the attached drawings, in which:
