DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a device for filling containers, particularly packaging containers such as cardboard packaging containers, with fluid through a fill opening on the packaging container, the device comprising a feed part and a closing part.
BACKGROUND OF THE INVENTION
When using a conventional feeding device such as described above, a problem that often arises is that drops of liquid keep dripping from the feeding device even after it has been closed. These liquid drops can stain the exterior surfaces of the packaging container, and they can be particularly harmful to cardboard containers which are closed by placing a cover strip on top of the fill opening and by using heat sealing to attache the cover strip to the edges of the fill opening. If drops of the filled product have spilled on the edge area around the fill opening, heat sealing cannot be performed reliably. The reason for this is particularly that in heat sealing it is not possible to use a temperature high enough to evaporate the liquid drops which may be present at the sealing area.
SUMMARY OF THE INVENTION
The object of the present invention is to present a device for filling containers, particularly packaging containers such as cardboard packaging containers, which is absolutely reliable in preventing the access of the distributed substance to the exterior surface of the packaging container. This can be achieved with the help of a device according to the invention, comprising a feed part and a closing part, characterized in that the feed part is equipped with outlets which form an angle (.alpha.) with the center axis of the feed part so that the upper ends of the outlets separate from each other.
A preferred embodiment of the device according to the invention for filling containers with fluid is thus created by equipping the feed part with outlets which form a specified angle (.alpha.) with the center axis of the feed part so that the upper ends of the outlets separate from each other. This angle position which depends on the length of the feed part causes the upper ends of the outlets to separate from each other, thus enabling the reliable and smooth flow of the filled substance to all outlets. In the lower end of the feed part the angle position of the outlets causes the liquid flows from different outlets to unite into one flow which, if necessary, can be fed into a container even through a small fill opening. The benefits of the conical shape of the closing part include on the one hand that the size of the feed openings of the outlets increases thus encouraging the reliable and smooth flow of liquid, and on the other hand that the liquid flow can be easily stopped when closing the device which contributes to the non-dripping quality of the feed part. When the feed part is equipped with an adequate number of outlets to produce the necessary flow area, yet limiting the diameter of an individual outlet according to the substance to be distributed, a device for filling containers which meets very strict non-dripping requirements can be created.
BRIEF DESCRIPTION OF THE DRAWING
The present invention is described by the following example with reference to the attached drawing, wherein:
FIG. 1, shows a device according to the invention for filling containers;
FIG. 2 shows an embodiment where a part of the length of the outlets is parallel to the center axis of the feed part;
FIG. 3 shows an embodiment where the shape of the outlets is conical; and
FIG. 4 shows an embodiment where the shape of the outlets is partly conical, partly cylindrical.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
FIG. 1 shows a device for filling containers, particularly packaging containers such as cardboard packaging containers, with fluid, the device comprising a feed part (1) and a closing part (2).
The device is opened by moving the closing part (2) upwards with respect to the feed part (1) so that the feed openings of the outlets (3) are released and the filled substance (4) lead to the feed part spreads to the outlets (
