Abstract
The present invention relates to a multiple-compartment container for dispensing flowable products by gravity. The container described comprises a first compartment (51) and second compartment (52) for storing a first and a second composition. The container also comprises a multiple-dispensing tap (100), which preferably is operable by a pressing action and is capable of dispensing flowable products from the first and second compartments substantially simultaneously.
Claims23
A container for dispensing flowable products by gravity comprising a first compartment, a second compartment and a dispensing tap comprising a first and second inlet, a hollow body defining a first and second outlet and a first and second channel wherein the first compartment is linked to the first inlet and the second compartment is linked to the second inlet of the dispensing tap, said tap further comprising a valve system for controlling flowable product through the outlet and means for operating the valve system.
A dual compartment container for dispensing two or more flowable products by gravity at constant volume ratio, comprising a first compartment and a second compartment each comprising a flowable product A and B respectively, the compartments being designed to satisfy the equation

- Product A is a Newtonian fluid and product B a Bingham fluid and wherein:
- Q is the flow rate of products A and B respectively;
- α is the volume ratio;
- R is the radius of each tap channel;
- L is the length of each tap channel;
- H is the liquid head of A and B respectively in each compartment;
- g is gravity;
- τ is yield stress;
- and,
- μ is the viscosity.
A multiple-dispensing tap suitable for attachment to a container comprising a first and second inlet, a hollow body defining a first and second outlet, a valve system for controlling flowable product through the outlet, a means for operating the valve system, and the hollow body comprises at least two channels capable of substantially simultaneously dispensing two different flowable products.
