Abstract
A medicine container for medicine substances which can be mixed with one another includes a container body, a stopper and a mixing element. The container body has a first end with a stopper opening and a second end with a base having an outlet. The stopper is displaceable between the ends. A mixing chamber for receiving the medicine substances is delimited by a portion of an inner casing surface of the container body, a side of the stopper and the base. The mixing element can be disposed in the mixing chamber. The medicine container is adapted to discharge the medicine substances from the medicine container by displacement of the stopper in the direction of the outlet. The stopper is adapted to receive the mixing element at least partially by a recess. The invention further relates to a method for operating such a medicine container.
Core Innovation
A medicine container is provided for storing and providing at least two intermixable medicine substances. The container body has a first end defining a stopper opening and a second end having a base with an outlet, and a stopper is insertable through the stopper opening and is displaceable along a longitudinal axis between the first and second ends.
The container includes a mixing chamber for receiving the at least two intermixable medicine substances. The mixing chamber is delimited by a section of an inner casing surface of the container body, and a mixing element is disposed in the mixing chamber. Discharge of the at least two intermixable medicine substances from the mixing chamber is adapted to occur through the outlet by displacement of the stopper toward the outlet.
When the stopper is disposed at the second end, the stopper is adapted to receive the mixing element at least partially by a recess formed on the side of the stopper facing the outlet, and the recess and the outlet are formed in alignment with each other. The base includes at least two first grooves opening into the outlet such that, at the position of the stopper at the second end, the at least two intermixable medicine substances are dischargeable through the outlet at least through the at least two first grooves.
Refinements described include groove geometry on the mixing element, surface matching between the mixing element and the base to avoid cavities outside groove regions, a separate base element carrying the outlet, and a double-chambered carpule arrangement with a mixing chamber separated from a second chamber by a stopper.
Claims Coverage
The claim coverage centers on the medicine container configuration for storing, mixing, and discharging at least two intermixable medicine substances using a longitudinally displaceable stopper and a mixing chamber discharged through a centrally disposed outlet aligned with a recess for receiving a mixing element. The claim set contains refinements in dependent claims that specify groove geometry, surface matching, separate base element structure, and a double-chambered carpule layout.
Longitudinally displaceable stopper with outlet-directed discharge
A medicine container adapted to at least partially discharge at least two intermixable medicine substances received in a mixing chamber from the medicine container through the outlet by displacement of the stopper toward the outlet, wherein the stopper is insertable into the container body and displaceable along a longitudinal axis between the first and second ends.
Mixing chamber with mixing element disposed therein
A mixing chamber for receiving the at least two intermixable medicine substances, wherein the mixing chamber is delimited by a section of an inner casing surface of the container body and a mixing element is disposed in the mixing chamber.
Recess and outlet alignment for receiving the mixing element
The stopper is adapted to receive the mixing element at least partially by a recess formed on a side of the stopper facing the outlet when the stopper is disposed at the second end of the container body, wherein the recess and the outlet are formed in alignment with each other.
Centrally disposed outlet with base grooves as discharge paths
The base includes at least two first grooves opening into the outlet, wherein at a position of the stopper at the second end of the container body the at least two intermixable medicine substances are dischargeable from the medicine container through the outlet at least through the at least two first grooves, and wherein the outlet is disposed, with respect to the longitudinal axis of the container body, in a central region of the base.
Groove geometry on the mixing element
The mixing element has an outer surface with at least one second groove, and wherein, when the stopper is positioned at the second end of the container body, at least two intermixable medicine substances are dischargeable through the outlet via the at least one second groove.
Surface matching to avoid cavities outside groove regions
The mixing element outer surface has a shape matching the base such that, when the stopper is at the second end, no cavity remains between the mixing element outer surface and the base in an area outside the at least one first and/or second groove.
Separate base element carrying the outlet
The base with an outlet is provided on a separate base element located on the container body at the second end.
Double-chambered carpule configuration with mixing chamber and second chamber
A double-chambered medicine container having a mixing chamber separated from a second chamber by a stopper, wherein the second chamber is positioned between the first end of the container body and the side of the stopper facing away from the outlet.
Overall, the claims cover a medicine container where stopper displacement toward a centrally disposed outlet discharges at least two intermixable medicine substances from a mixing chamber, with a recess on the stopper side aligned to receive the mixing element and base grooves providing discharge paths. Dependent refinements further define groove structures on the base and mixing element, surface matching to prevent cavities, an outlet on a separate base element, and a double-chambered carpule configuration.
