[0068] The first air layer forming portion (128) may take the form of inclined portions in opposite directions to form an air layer between the inner part (124) of the outer cap and the inner part (132) of the inner cap when the outer cap (120) and the inner cap (130) are combined together with the second air layer forming portion (137).

[0069] FIG. 5 is a perspective view of the inner cap of a double-cap container having a double blocking structure according to one embodiment of the present invention.

[0070] Referring to FIGS. 3 and 5, the inner cap (130) has a double structure of an outer portion (131) of the inner cap and an inner portion (132) of the inner cap, and forms a flow path through which the liquid in the bottle (110) can flow between the outer portion (131) of the inner cap and the inner portion (132), and can also form a bridge (133) connecting the outer portion (131) of the inner cap and the inner portion (132) of the inner cap to each other.

[0071] The bridge (133) can form a path through which the liquid inside the bottle (110) can flow between the outer part (131) of the inner cap and the inner part (132) of the inner cap.

[0072] Since a euro is formed, a plurality of bridges (133) are spaced apart from each other to connect the outer side of the inner cap (131) and the inner side of the inner cap (132) to each other, thereby creating a euro space.

[0073] At this time, a first sealing groove (139) is formed between the lower part of the bridge (133) and the lower part of the inner cap (130) to seal by combining with the first sealing protrusion (126), and a sealing rib (141) is further formed in the circumferential direction (in the shape of a ring or band) to increase the sealing force.

[0074] The sealing rib (141) is formed in a cylindrical shape along the lower end of the inner side of the inner cap (132) in the circumferential direction, and can be formed by being attached to the inner lower surface of the bridge (133).

[0075] The space formed between the sealing rib (141) and the inner side of the inner cap (132) forms a first sealing groove (139).

[0076] In the absence of a sealing rib (141), the space formed by the bridge (133) and the inner side of the inner cap (132) forms a first sealing groove (139), but since a plurality of bridges (133) are formed spaced apart from each other to form a flow path space, the first sealing groove (139) is also formed corresponding to the bridge (133), and there is a problem that the sealing function is lost in the space where the first sealing groove (139) is not formed.

[0077] Accordingly, to solve this problem, a sealing rib (141) is further formed in the circumferential direction on the inner side of the lower part of the bridge (133) so that the first sealing groove (139) itself is formed in the shape of a perfect circle, thereby increasing the sealing force between the first sealing groove (139) and the first sealing protrusion (126), thereby completely blocking moisture or liquid from seeping into the positioned granules of the inner cap (130).

[0078] The bottom part (134) of the inner cap (130) can have a solid positioned thereon, and an upward protrusion (135) protruding from the outer periphery of the bottom part (134) can be formed.

[0079] The upper outer circumference of the connecting portion (130) has a structure in which a fastening bend portion (136) is formed in a downwardly bent shape so that it can be fastened to the upper end of the bottle (110).

[0080] A screw thread (138) may be formed on the inner wall of the outer part (131) of the inner cap, which is used to be combined and fastened with the screw thread of the outer cap (120).

[0081] The first sealing groove (139) is grooved and coupled with the first sealing protrusion (126) of the outer cap (120) to primarily perform a liquid and moisture blocking function, and the second sealing protrusion (140) is grooved and coupled with the second sealing groove (127) of the outer cap (120) to secondarily perform a liquid and moisture blocking function.

[0082] Figure 6 is a cross-sectional view of a double-cap container having a double blocking structure according to one embodiment of the present invention.

[0083] As illustrated in FIG. 6, the double-cap container (100) of the present invention has a structure in which the inner cap (130) is fastened to the inside of the upper opening of the bottle (110) and the outer cap (120) is fastened over it.

[0084] The first screw thread (125a) of the outer cap (120) is connected to the screw thread formed on the outer circumference of the bottle (110) to have a first connection structure, and the second screw thread (125b) is connected to the screw thread (138) of the inner cap (130) to have a second connection structure, so that the entirety can have a double connection structure.

[0085] A double wall is formed by the structure of the outer cap outer part (123) and the inner part (124) of the outer cap (120), and the screw tap connection with the bottle (110) and the inner cap (130) is possible by the first screw thread (125a) of the outer cap outer part (123) and the second screw thread (125b) of the outer cap inner part (124), which can form a plurality of external moisture barriers.
