In addition, Figures 4 to 8 are views for explaining the opening and closing operation of the tube cap, Figure 9 is a perspective view of the main portion in a state in which the tube cap is cut.

Referring to FIG. 1, a tubular container 1 according to an embodiment of the present invention includes a tube 10 in which contents (eg, cosmetics, in particular, an antiseptic cosmetic) and a tube cap 100 mounted to the tube. ). The tube cap 100 has a structure capable of selectively leaking the contents in the tube 10 to the outside, and has a housing 141 and an lid 142 openly mounted to the housing 141 to form an exterior. Include. For example, when the user presses the tube 10 while the lid 142 is opened, the contents in the tube 10 move out of the tube cap 100 and then flow out of the tube cap 100.

2 and 3, the tube 10 has a first discharge port 11 and a second discharge port 12. In this case, the first discharge port 11 may have a larger flow cross-sectional area than the second discharge hole 12. In addition, the first discharge port 11 may be located closer to the central axis of the tube 10 than the second discharge hole 12. In addition, the tube 10 may be divided into an upper region 13 and a lower region 14 provided with the first and

second discharge ports

11 and 12, and the upper region 13 and the lower region 14 may be It may have a bonded structure.

3 and 4, the tube cap 100 is mounted to the tube 10. In addition, the tube cap 100 is mounted to the tube 10 to surround the first and

second discharge ports

11 and 12. In addition, the tube cap 100 has an outlet 131 for selectively outflowing the contents (H) in the tube 10 to the outside.

3 to 5, the tube cap 100 includes a first sealing part 112, a first flow passage P1, and a second flow passage P2.

In detail, the tube cap 100 includes a first sealing part 112 and a tube 10 passing through the first sealing part 112 provided to selectively seal the first discharge port 11 of the tube 10. Is connected to the first flow passage (P1) and the second discharge port (12) of the tube (10) which is provided to move toward the outlet (131) in fluid communication with the first flow passage (P1) And a second flow passage P2 that is fluidly connected.

In addition, the second flow passage (P2) is inside the tube (10) and the second flow passage (P2) through the second discharge port 12 in a state where the first sealing portion 112 seals the first discharge port (11). ) So that fluid movement is possible. In this structure, when the sterilization gas is injected into the tube cap 100 through the second discharge port 12, the sterilization gas is in a state in which the first sealing part 112 seals the first discharge port 11. Passing through the second discharge port 12 and the second flow passage (P2) may be delivered to the first flow passage (P1).

Meanwhile, the tube cap 100 may further include a filter 160 disposed at the second discharge hole 12 to contact the contents of the tube 10. The filter 160 may be used to sterilize a portion in contact with the contents H in the tube 10.
