  • Patent number: 5060791
    Abstract: The invention relates to a two-chamber container in which two separate components are to be mixed together to make a ready-to-use preparation before it is dispensed from the container, and which are contained in two chambers, an upper container and a lower container chamber, disposed one above the other in a container housing. The container chambers are connected to one another by a passage running from the top of the lower container chamber into the bottom of the upper container chamber. A separating plug stops this passage. The plug can be displaced into one of the container chambers by a plunger element which can be displaced in a vertical direction from the outside, so that the components can flow together and be mixed with one another within the container.

  • Patent number: 4607762
    Abstract: A dosaging device for dispensing defined amounts of a liquid being contained in a bottle with a squeezable wall. A valve is disposed between the content of the bottle and the dosaging container which can be selectively opened or closed by turning a gripping piece. The openings for feeding the bottle content into the dosage container are arranged in a specific manner with respect to the pouring orifice. An oblique trough which encompasses the pouring orifice reduces the still remaining liquid in the area of the pouring orifice back into the dosaging container, after the pouring. Baffle ribs are mounted on the inner side of the lid which covers the dosage container to the outside and which contains the pouring orifice in such a manner that they limit the liquid film formed by the impact of the liquid streams on the inside of the lid in direction of the opening provided for pouring.
