A tube squeezer consists of a housing, which has a slot. To reduce the cost and to simplify the design at least one of the walls of slot or both walls have an elastic lip. The lip can be made from two plates, one of which with one edge is fastened to the housing near the wall of slot, and connected by second edge with the second plate at an angle of 10-60°, and the second edge of the second plate is brought closer to the wall of slot or to the second elastic lip. The angle between plates of two lips brought closer makes 20-60°. Butt end of plates brought closer to each other of both lips can be truncated by imaginary planes, which intersect along the slot at an angle of 60-120°. |
