A disctop is a one-touch dispensing closure where one half of the disc is pushed down; the other side pops up, revealing the orifice on the side. The bottle is then squeezed to dispense the product. Once finished, the disc is pressed down to hide the orifice and seal the closure. This type of closure is often used with a 'squeezable' bottle - wider or longer bodied bottles with a flexible panel - and are most commonly seen on shampoos, conditioners, lotions, ointments and other more viscous liquids.
With a fliptop, the whole diameter of the cap hinges up to reveal the nozzle. The bottle is then squeezed to dispense the product through the nozzle. Once completed, the hinged part of the cap is pressed back down to seal the closure - this has an insert that fits into the nozzle to prevent product spilling out.
Fliptops make for an easy one handed operation and keeps pouring, dropping and squeezing very simple. Again, this closure is best paired with a bottle that can be squeezed in order to dispense the product, but this can be dependant on the product's viscosity. Similar to the disctop, this type of closure is often used for shampoos and other personal care products.
Neither of these dispensing methods offer airless protection. See our airless range for more information.
