The present invention relates to a dispenser for feeding out convenient units of two liquid products. The dispenser (1), preferably, is intended for manual handling and manual feed-out of viscous products, such as mustard (2), ketchup (3), or similar sauces on food products, such as hamburger bread rolls (4) or the like. To bring about an essential reduction of the time required for feeding out convenient units of the two liquid products (2, 3), the dispenser (1) was a first container (5) holding one liquid product (3), a second container (15) positioned within the first container, the second container holding the other liquid product (2), and a pump assembly (18) adapted to simultaneously feed out convenient units of the two liquid products (2, 3) from their respective containers (5, 15).
