Kind Code:

Abstract:
An extrusion discharging type hose, comprising a cover assembly, an inner plug (30) and a pipe body (40), wherein the pipe body is provided with a main body (41) for accommodating material and an injection shoulder (42) extending from the main body; the inner plug is sealed and fixedly inserted into the injection shoulder; the cover assembly is assembled on the injection shoulder; a sealing structure is provided between the inner plug and the cover assembly, and a discharging channel (24) is formed between the inner plug and the cover assembly; when the cover assembly is tightened onto the injection shoulder, the sealing structure blocks the discharging channel; and after the cover assembly is rotated from a tightened position, the sealing structure is separated from the discharging channel, so that the material in the main body can flow out through the discharging channel. When the hose is used, a user does not need to remove the cover assembly, thus pollution on the cover assembly is avoided, and the use convenience of the hose is improved.
