Push-button dispensers are mainly designed for movie theatre concession stands. They are normally filled with a buttery flavored topping and are perfect for flavoring up large bags or tubs of popcorn. These machines are bright and enticing with exciting graphics to gain customers’ interest. Every time the button or trigger bar is pressed, a few milliliters of topping flows out to douse the popcorn in butter. Push-button dispensers are usually stainless steel with a plastic lid and a stainless steel bowl for the interior. These dispensers are designed for butter, keeping the liquid within a temperature range of about 85 degrees to 185 degrees Fahrenheit. For dispensers with a trigger bar, the butter liquid automatically dispenses when a popcorn tub is pressed against the bar, reducing messy spills and providing customers the convenience of hands-free operation.
