PROBLEM TO BE SOLVED: To provide a syringe-type spout container capable of spraying content liquid with air mixed even if the amount of the content liquid is small.SOLUTION: A spout container 1 includes a spout part 10 and an operation part 50. The operation part 50 includes: a syringe 51 having a small diameter tip cylinder part 51c; a piston 52; and a rod 54a forming a circular gap rto the tip cylinder part 51c and projecting from the tip cylinder part 51c due to pushing force applied by the piston 52. The spout part 10 includes: an outer cylinder part 11 having a spout port 1a; an intermediate cylinder part 13 having a throughhole 13a leading to the spout port 1a and set inside the outer cylinder part 11; an inner cylinder part 14 set inside the intermediate cylinder part 13; a plunger 16 pushing out content liquid M in the inner cylinder part 14; and a spin element 15 set at the side of the throughhole 13a inside the intermediate cylinder part 13 together with the inner cylinder part 14 and provided with a swirl groove r. Between the intermediate cylinder part 13 and the outer cylinder part 11, a liquid passage Sthrough which the content liquid M pushed out from the throughhole 13a, is flown to the spout port 1a, and an air passage rto rthrough which the air joining into the liquid passage Sand pushed out from the gap ris circulated, are formed. |
