Patent ID: 7556618

Claim:
A multichamber ampoule to dispense a mixture consisting of several substances, said ampoule comprising: a container with at least two chambers that are arranged parallel to each other, and each of which possesses an open back end to feed in one of the substances and subsequently insert a plunger into the chamber, and a front end that is provided with an outlet opening, and a hollow cylindrical neck formed at the front ends of the chambers into which all of the outlet openings of the chambers feed; a multiple-plug closure that can be inserted into the neck with a plate-shaped body and with at least two plugs provided on an underside of the body, each of said plugs project from the underside of the body downward and penetrate the outlet opening of one of the chambers when the multiple-plug closure is inserted into the neck, in which case the multiple-plug closure is formed such that the plugs assume a closed position in a first penetration position in which the outlet openings have a fluid-tight seal; and in a second penetration position assume a flow position when pushed further back, in which case fluid is permitted to flow through the outlet openings; an adapter with a dispenser channel passing through the adapter, and with a cylindrical back section that fits with the hollow cylindrical neck, the adapter being fluid tight when connected to the multiple-plug closure in the neck and in an inserted state can be pushed and rotated, when rotating the adaptor causes the adaptor to move backward and also causes the plugs to move from a locked position to a flow position; and, a locking mechanism formed on the container and adapter, which interact such that they prevent the adapter from being slid forward from the locked position into the flow position once the plugs have been slid by the adapter; wherein the plate-shaped body of the multiple-plug closure is mounted at the back section of the adapter such that it can be rotated, and the locking mechanism is formed such that the adapter can be rotated into an unlocked position relative to the multiple-plug closure that is not rotatable in the outlet openings of the chambers, in the unlocked position the adapter is no longer locked and can be removed from the neck of the container together with the multiple-plug closure and is separable from the container.
