BRIEF SUMMARY
BACKGROUND
1. Field of the Invention
This invention relates generally to a container system for accommodating at least two substances held separately in closable containers,and more particularly to such a system comprising at least two containers with closures connected to one another in a manner permitting a user to selectively open the closures for combining the two substances together another in such a way that the container volumes are connected together, and to a method for combining at least two substances held separately in predetermined quantities in closed containers of a container system, the at least two containers with an intermediate closure disposed in between and closures facing one another being connected to one another and the connected containers being opened by movement relative to one another so that the at least two substances can be combined.
2. Discussion of Related Art
There are many known multicomponent systems which are only supposed to be combined immediately before use so that the reaction initiated by their combination does not take place beforehand. It is also known that, in many cases, such multicomponent systems only function properly when the individual components are dispensed in certain ratios to one another.
There are various known double compartment systems in which two-component substances are stored separately in closed form and, in order to combine the substances, the container closures are opened before use by destruction, for example by cutting open or by piercing the closure material. DE 44 36 863 relates to a double compartment system in which the containers are closed by firmly wedged stoppers which are mutually forced from their closed position by being turned relative to one another, thereby opening connecting passages between the containers. However, this has the disadvantage that the container openings are seriously constricted and the substances to be combined are impeded by, and adhere partly to, the constrictions between the containers and their openings.
SUMMARY OF THE INVENTION
An object of the invention is to provide an inexpensive container system for containing at least two substances in separate but joined respective containers, which after opening of the closures between the containers, the resultant openings permit free passage of the substances between the containers for mixing the substances together for later dispensing from one of the containers.
The technical problem addressed by the present invention was to provide an inexpensive container system in which, after opening of the closures, the container openings would be very largely free and which would be reusable, and a method by which this problem could be solved in a simple uncomplicated manner.
With the problems of the prior art in mind, in one embodiment of the invention, the joined containers include screw closures, whereby the closures between the containers can each be opened and closed by screw connection means which turn in opposite directions between adjacent containers.
According to the invention, this problem has been solved by designing a container of the type defined at the beginning in such a way that the closures are screw closures and one of the containers is designed to be closed by a combination of closure and intermediate closure and by a method in which the two containers can each be opened and closed by screw connections which turn in opposite directions.
A container system such as this has the advantage that the respective containers can be filled with the individual substances--as components of a multicomponent system--in the correct amounts and closed by the manufacturer. The containers thus prepared can be connected to form a system in which the individual substances are present in the correct respective proportions and can never be confused. Just before use, the containers connected in the system need only be moved relative to one another to be opened in such a way that the container volumes are connected to one another without the container openings being seri
