how does toothpaste get out of the tube in 3 separate straight colour lines??

Answer 1

Striping of toothpaste is solely for the purpose of an interesting appearance; it provides no functional benefit to the consumer.

Striped toothpaste can be produced by including two different colored toothpastes in an unusual type of packaging. The collapsible tube has two tanks, one filled with each color paste. Squeezing the tube pushes the two pastes out the opening. The tube nozzle layers the pastes to produce a striped pattern.

To keep the cost of packaging to a minimum, it is now common for tubes to be filled with striped paste (e.g. Aquafresh). As the tube is squeezed, the stripes flow parallel to each other and do not mix. The patterned paste that gets dipensed is simply a narrower version of what is in the tube. Filling is done using a multi-nozzle filling head that dispenses a different colored stripe in each direction. To keep the stripes parallel to the axis of the tube, the head starts at the bottom and retracts as it fills, staying just above the level of the paste. Tubes with two compartments are generally reserved for toothpastes containing two formulas intended to react together and therefore kept isolated until dispensed (e.g. Colgate Simply White).

Sounds like another fine question from science tacher Mr. Fesperman. You can also call the toothpaste company and they will give you an answer.
