Abstract

Abstract Container apparatus for storing at least two components and for mixing the same according to a predetermined ratio includes a container in whose interior at least two chambers are defined, each chamber having a hollow interior space therein. The ratio of the cross-sectional areas of the interior spaces of the at least two chambers is constant at any level when the container is oriented in an ordinary or storage position. An opening is provided for each chamber so that a respective component can be charged into the hollow interior space defined thereby. The hollow interior spaces of the various chambers are fluidly interconnected with each other.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 247 words
Container apparatus for storing at least two components and for mixing the same according to a predetermined ratio, comprising: means for defining at least two chambers, each chamber having a hollow interior space defined therewithin, and wherein the ratio of the cross-sectional areas of the interior spaces of said at least two chambers is substantially constant at any level of the apparatus when the latter is oriented in a storage position, said chamber defining means including a container having bottom, side and upper walls and a partition wall located within said container, said partition wall having connected to said container bottom and side walls along its bottom and side edges respectively to define said at least two chambers, said partition wall having a top edge which is spaced below the upper wall of said container, the space defined between said partition wall top edge and said upper wall of said container forming a passage interconnecting said hollow interior spaces of said at least two chambers with each other; at least two opening means formed in said container, each opening means communicating with only a respective one of said at least two chambers when the apparatus is oriented in the storage position, whereby each respective component can be charged into the hollow interior space defined by a respective chamber through the respective openings means communicating therewith; and at least two lid members, each of said lid members being adapted to close a respective one of said openings means.
Claim 2
Dependent Claim 247 words
Container apparatus for storing at least two components and for mixing the same according to a predetermined ratio, comprising: means for defining at least two chambers, each chamber having a hollow interior space defined therewithin, and wherein the ratio of the cross-sectional areas of the interior spaces of said at least two chambers is substantially constant at any level of the apparatus when the latter is oriented in a storage position, said chamber defining means including a container having bottom, side and upper walls and a partition wall located within said container, said partition wall having connected to said container bottom and side walls along its bottom and side edges respectively to define said at least two chambers, said partition wall having a top edge which is spaced below the upper wall of said container, the space defined between said partition wall top edge and said upper wall of said container forming a passage interconnecting said hollow interior spaces of said at least two chambers with each other; at least two opening means formed in said container, each opening means communicating with only a respective one of said at least two chambers when the apparatus is oriented in the storage position, whereby each respective component can be charged into the hollow interior space defined by a respective chamber through the respective openings means communicating therewith; and at least two lid members, each of said lid members being adapted to close a respective one of said openings means.
