Abstract
A multichamber container such as a multichamber tube or multichamber pump can deliver the contained products in varying arrays by the use of container shoulders of different channel configurations. The container body remains the same with chamber dividing walls extending from the container base to the container shoulder. The container shoulder attachment to the container walls and to the chamber dividing walls can remain essentially the same. Within the shoulder, channels direct the flow of each product so that it has a number of arrays from an A/B/A sandwich to axial arrays to semiconcentric arrays to fully concentric arrays. The channels that are a part of the shoulder will direct the product from each chamber to be dispensed in a single stream or multiple streams. Also, the streams can be shaped to many different shapes by the shape and the arrangement of the channels in the shoulder.
