To provide a simple dual tube squeezer that uniformly squeezes two tube containers simultaneously, mixes the contents in the two tube containers equally and discharges it.

A pair of rollers R have rotation operation parts 41 having circumferential gears engaging with each other. Gear shafts 42 on both ends are inserted in parallel grooves 13 in the body A of the device and engage with a rack 14. The rollers move up, while uniformly and simultaneously squeezing the two tube containers C attached in the device body A. The contents of the two tube containers C move through a communication path 7 formed by attaching a cover B to the device body A, and merge at an upper end of a neutral piece 8, to be mixed equally and discharged from an outlet 20.
