To provide an automatic sealed structure type cap of a tube container configured so that a nozzle from which chemical is ejected may appear and disappear in a non-contact manner by using a drying prevention device.
The automatic sealed structure type cap of the tube container 400 includes: a conical part 100 which is formed in hollow tube shape, and has a nozzle hole 11 formed at one end, where a nozzle 300 appears and disappears, and an insertion hole 14 formed at the other end, and has a pair of locking projections 101 formed on an opposite side to each other on the external wall on the insertion hole 14 side; a body 200 which has an insertion hole at one end in which the conical part 100 is inserted, and includes a cap 210 constituting a bottom part at the other end, and has a fixed tube 230 formed to pierce through the inside from the center of the bottom part and project to the outside, and also has guide holes 220 formed at corresponding positions so that the locking projections 101 may move while being restricted; a tube 400 which is filled with content, and has a screw 403 formed at an injection part from which the content is ejected, to be coupled with a screw thread 232 on the other side of the fixed tube 230; and a drying prevention device part lying between the body 200 and the conical part 100, which opens/closes the nozzle hole 11 of the conical part 100 that advances and retreats from the body 200 to be airtight.
