Mode for the Invention [37] Reference will now be made in detail to the preferred embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. [38] FIG. 1 is a disassembled perspective view showing a closure of a vessel according to the first embodiment of the present invention, FIG. 2 is a sectional view showing a state that the closure of a vessel is mounted on a vessel inlet according to the first embodiment of the present invention, and FIG. 3 is a sectional view showing a state that the closure of a vessel is coupled to the vessel inlet according to the first embodiment of the present invention. [39] The closure of a vessel according to the present invention comprises a closure body

20 having an inner space and coupled to a vessel inlet 10, and a supplementary closure 30 inserted into a lower inner surface of the closure body 20.

[40] In order that a user may easily rotate the closure body 20, protrusions 22 are formed on an outer circumferential surface of the closure body 20 in a circumferential direction with regular interval therebetween. A female screw portion 24 screw-coupled to a malescrew portion 12 formed on an outer circumferential surface of the vessel inlet 10 is formed at an inner surface of the closure body 20.

[41] A lower portion of the closure body 20 may have a diameter larger than that of an upper portion thereof. A receiving groove 26 for being inserted with the supplementary closure 30 is formed at an inner surface of the closure body 20.

[42] The supplementary closure 30 includes a supporting portion 32 inserted into the receiving groove 26 of the closure body 20; a sealing portion 34 connected to an upper end of the supporting portion 32, and coupled to the vessel inlet 10; and a skirt portion 36 connected to a lower end of the supporting portion 32 and locked by an outer circumferential surface of the vessel inlet 10, for checking whether the closure of a vessel has been opened from the vessel inlet 10.

[43] The supporting portion 32 is formed ina cylindrical shape, and has a plurality of connection ribs 38, 40at upper and lower ends of the supporting portion 32 with a regular interval. The connection ribs 38, 40are respectively connected to an outer circumferential surface of the sealing portion 34 and the skirt portion 36.

[44] That is, the upper end of the supporting portion 32 is connected to the outer circumferential surface of the sealing portion 34 by a first connection rib 38, and the lower end of the supporting portion 32 is connected to an upper end of the skirt portion 36 by a second connection rib 40.

[45] The connection ribs 38, 40 are formed as thin films and are broken when a certain force is applied thereto, thereby respectively separating the supporting portion 32 and the sealing portion 34 from each other, and separating the supporting portion 32 and the skirt portion 36 from each other.

[46] The sealing portion 34 is disposed at an upper side of the vessel inlet 10 thus to seal the vessel. The sealing portion 34 includes a mounting portion 42 inserted and coupled to an upper surface of the vessel inlet 10 thus to be fixed to the vessel inlet 10, and a sealing plate 44 integrally formed at an inner surface of the mounting portion 42 as a disc shape for sealing the vessel inlet 10.

[47] When the mounting portion 42 is inserted into an upper surface of the vessel inlet

10, one side of the mounting portion 42 is closely contacted to an upper outer surface of the vessel inlet 10, and the other side thereof is closely contacted to an upper inner surface of the vessel inlet 10. Accordingly, the mounting portion 42 is elastically inserted and coupled to the vessel inlet 10 in an elastic state.

[48] A contacting protrusion 46 is inwardly bent at the end of the mounting portion 42 thus to be closely contacted to the surface of the vessel inlet 10, thereby preventing the mounting portion 42 from being separated from the vessel inlet 10. A contacting protrusion 48 for enhancing a close contacting state between the mounting portion 42 and the vessel inlet 10 may be formed at an upper inner surface of the mounting portion 42 as well as on both side surfaces of the mounting portion 42.

[49] A discharge passage 50 through which contents stored in the vessel is discharged out is formed at the sealing plate 44.

[50] As shown in FIG. 4, the sealing plate 44 may have a discharge passage 52 implemented as a plurality of holes according to the kind of contents stored in the vessel. That is, according to the kind of contents stored in the vessel, another type of the discharge passage may be formed at the sealing plate 44.

[51] A sealing protrusion 56 may be protruding from an upper surface of the mounting portion 42 in a circumferential direction, and a sealing groove 58 for being inserted and coupled with the sealing protrusion 56 may be formed at an upper inner surface of the closure body 20.

[52] That is, once the closure body 20 is mounted at the vessel inlet 10, the sealing protrusion 56 is inserted into the sealing groove 58. Accordingly, contents discharged through the discharge passage 50 is prevented from being discharged out.

[53] The skirt portion 36 is formed ina cylindrical shape, and is detachably connected to a lower end of the supporting portion 32 by the second connection rib 40. Also, a locking groove 62 for being locked with a locking protrusion 60 formed at the vessel inlet 10 is formed at an inner surface of the skirt portion 36. A saw teeth portion 64 engaged with saw teeth 61 formed at the locking protrusion 60 is formedat an inner surface of the locking groove 62, thereby preventing the skirt portion 36 from being rotated.

[54] An assembly process of the closure of a vessel according to the present invention will be explained in more detail.

[55] FIG. 5 is a sectional view showing a state that the closure of a vessel is separated from the vessel inlet according to the first embodiment of the present invention.

[56] First, the closure body 20 and the supplementary closure 30 are individually fabricated. The supplementary closure 30 is integrally formed so that the supporting portion 32 is connected with the sealing portion 34 respectively by the first connection rib 38 and the second connection rib 40.

[57] Under this state, the supplementary closure 30 is inserted and coupled to an inner surface of the closure body 20. Then, the supporting portion 32 of the supplementary closure 30 is inserted and coupled to the receiving groove 26 formed at the closure body 20, thereby fabricating the closure body 20 and the supplementary closure 30 as one assembly. [58] The fabricated closure in one assembly is transferred to a production line. And, contents is filled into the vessel, and the closure of a vessel is disposed at an upper surface of the vessel inlet 10. When a force is downwardly applied to the closure of a vessel, the mounting portion 42 of the sealing portion 34 is inserted into an upper end of the vessel inlet 20. At the same time, the first connection rib 38 connecting the supporting portion 32 with the sealing portion 34 is broken, thereby inserting the closure body 20 into the vessel inlet 10.

[59] Here, the female screw portion 24 formed at an inner surface of the closure body 20 is fitted into the male screw portion 12 formed on an outer circumferential surface of the vessel inlet 10. Also, the locking protrusion 60 formed on an outer circumferential surface of the vessel inlet 10 is locked in the locking groove 62 formed at the skirt portion 36.

[60] The sealing protrusion 56 formed at an upper surface of the sealing portion 34 is inserted into the sealing groove 58 formed at an upper inner surface of the closure body 20, thereby sealing the inside of the vessel.

[61] Once the closure of a vessel is mounted at the vessel inlet 10 with a single process, the sealing portion 34 is hermetically mounted at the vessel inlet 10 and the skirt portion 36 is coupled to the vessel inlet 10.

[62] Accordingly, a process for mounting the closure of a vessel to the vessel inlet is simplified, and productivity is enhanced.

[63] Under the state that the closure of a vessel has been mounted at the vessel inlet 10, when contents stored in the vessel is to be discharged out, a user rotates the closure body 20 by grasping an outer circumferential surface of the closure body 20. Then, the second connection rib 40 for connecting the skirt portion 36 and the supporting portion 32 is broken by the rotating force applied to the closure of a vessel, thereby separating the skirt portion 36 and the supporting portion 32 from each other. As a result, whether the closure of a vessel has been initially opened from the vessel inlet 10 can be checked.

[64] When the closure body 20 is further rotated, the closure body 20 is separated from the vessel inlet 10 while being rotated in opening direction. Here, if the vessel is inclined, contents stored in the vessel is discharged outwardly through the discharge passage 50 formed at the sealing plate 44. When the closure body 20 is mounted at the vessel inlet 10 after using the contents, the sealing protrusion 56 formed atan upper surface of the sealing portion 34 is inserted into the sealing groove 58 formed at an upper inner surface of the closure body 20, thereby sealing the vessel.

[65] FIG. 6 is a sectional view showing a closure of a vessel according to the second embodiment of the present invention, FIG. 7 is a sectional view showing a state that the closure of a vessel is mounted at a vessel inlet according to the second embodiment of the present invention, and FIG. 8 is a sectional view showing a state that the closure of a vessel is separated from the vessel inlet according to the second embodiment of the present invention.

[66] The closure of a vessel according to the second embodiment comprises a closure body 70 and a supplementary closure 71 similar with the closure of a vessel according to the first embodiment.

[67] The closure body 70 has the same structure as the closure body 20 of the first embodiment except that a sealing portion mounting portion 74 for mounting a sealing portion 72 of the supplementary closure 71 within the closure body 70 is formed at an upper inner circumference of the closure body 70.

[68] The supplementary closure 71 in accordance with the second embodiment includes a supporting portion 76 inserted into a receiving groove 75 of the closure body 70; a sealing portion 72 for sealing the vessel inlet 10, the sealing portion 72 being connected to an upper end of the supporting portion 76; a skirt portion 77 connected to a lower end of the supporting portion 76 and locked by an outer circumferential surface of the vessel inlet 10, for checking whether the closure body 70 has been opened from the vessel inlet 10.

[69] The supporting portion 76 and the skirt portion 77 have the same structure as the supporting portion 32 and the skirt portion 36of the first embodiment, and thus detailed explanations will be omitted.

[70] An outer circumferential surface of the sealing portion 72 is connected to an upper end of the supporting portion 76 by a first connection rib 78. An edge of the sealing portion 72 is closely contacted to an upper end of the vessel inlet 10, and is inserted and coupled to the sealing portion mounting portion 74 formed at the closure body 70.

[71] A central portion of the sealing portion 72 having a disc shape has a height lower than that of the edge portion, thereby being inserted into the vessel inlet 10.

[72] When the closure body 70 is mounted at the vessel inlet 10, the sealing portion 72 is separated from the supporting portion 76, and then is mounted at the sealing portion mounting portion 74 formed at the closure body 70 thus to maintain a fixed state to the closure body 70.

[73] When the closure body 70 is opened from the vessel inlet 10, the vessel inlet 10 is completely opened. On the contrary, when the closure body 70 is closed to the vessel inlet 10, the sealing portion 72 mounted within the closure body 70 is closely contacted to an upper surface of the vessel inlet 10 thus to seal the vessel.

[74] A process for mounting the closure of a vessel to the vessel inlet according to the second embodiment will be explained. First, contents is filled into the vessel, and the closure body 70 is disposed at an upper surface of the vessel inlet 10. When a force is downwardly applied to the closure body 70, the first connection rib 78 connecting the supporting portion 76 and the sealing portion 72 is broken, thereby inserting the closure body 70 into the vessel inlet 10.

[75] Here, a female screw portion 80 formed at an inner surface of the closure body 70 is fitted into a male screw portion 81 formed on an outer circumferential surface of the vessel inlet 10. Also, a locking protrusion 83 formed on an outer circumferential surface of the vessel inlet 10 is locked in a locking groove 82 formed at the skirt portion 77.

[76] The sealing portion 72 is mounted at the sealing portion mounting portion 74 formed at the closure body 70, and is closely contacted to an upper end of the vessel inlet 10 thus to seal the vessel. Accordingly, the sealing portion 72 serves as a sealing member.

[77] Under the state that the closure body 70 has been fully mounted at the vessel inlet

10, when contents stored in the vessel is to be discharged out, a user rotates the closure body 70 by grasping an outer circumferential surface of the closure body 70. Then, a second connection rib 79 connecting the skirt portion 77 and the supporting portion 76 is broken by the force applied to the closure body, thereby separating the supporting portion 76 and the skirt portion 77 from each other. As a result, whether the closure of a vessel has been initially opened from the vessel inletlO can be checked.

[78] When the closure body 70 is furtherrotated, the closure body 70 is separated from the vessel inlet 10 while being rotated in opening direction. Here, if the vessel is inclined, contents stored in the vessel is discharged outwardly through the vessel inlet. The sealing portion 72 maintains a mounted state to the sealing portion mounting portion 74 formed at the vessel body 70.

[79] FIG. 9 is a sectional view showing a closure of a vessel according to the third embodiment of the present invention.

[80] The closure of a vessel according to the third embodiment has the same structure as the closure of a vessel according to the first embodiment except that a cover 85 for opening and closing an upper surface of a closure body 86 is mounted at an upper surface of the closure body 86.

[81] That is to say, the closure of a vessel according to the third embodiment comprises a closure body 86 coupled to a vessel inlet 10, and a supplementary closure 30 mounted at an inner surface of the closure body 86. A cover 85 for opening and closing an upper end of the closure body 86 may be mounted at an upper surface of the closure body 86.

[82] The upper end of the closure body 86 may be opened, the cover 85 may be rotatably mounted at one side of the upper end of the closure body 86 by being connected to a hinge rib 91, and a hand grip 90 held by a user when the cover 85 is to be opened may be formed at the other side of the cover 85. Locking portions 88, 89 for maintaining a closed state of the cover 85 to the closure body 86 may be formed between the other side of the cover 85 and the other side of the closure body 86.

[83] The locking portions 88, 89 may be composed of a locking groove 88 formed at an inner surface of one side of the cover 85; and a locking protrusion 89 formed at one side of an upper end of the closure body 86, and inserted into the locking groove 88.

[84] In the closure of a vessel according to the third embodiment, when the cover 85 is opened from the closure body 86, a discharge passage 50 is outwardly exposed. Accordingly, once the cover 85 is opened without opening the closure body 86 entirely from the vessel inlet 10, contents stored in the vessel can be discharged out.

[85] FIG. 10 is a sectional view showing a closure of a vessel according to the fourth embodiment of the present invention.

[86] Like the closure of a vessel according to the third embodiment, the closure of a vessel according to the fourth embodiment has a cover 94 detachably mounted at an upper surface of a closure body 93, and the cover 94 may be screwed and coupled with the closure body 93. The cover 94 and the closure body 93 may be coupled to each other in a snapping manner by protrusion and groove.

[87] More concretely, a male screw portion 95 is formed at an outer circumferential surface of an upper end of the closure body 93, and a female screw portion 96 is formed at an inner surface of the cover 94. When the cover 94 disposed on an upper end of the closure body 93 is rotated in one direction, the cover 94 is mounted at the closure body 93. On the contrary, when being rotated in the other direction, the cover 94 is separated from the closure body 93.

[88] In the present invention, a supplementary closure having a sealing function and a skirt portion is coupled to a closure body, thereby additional sealing member and skirt portion when a closure of a vessel is coupled to a vessel are unnecessary. The closure body may have various structures such as a CRC as well as the structure aforementioned in the first to fourth embodiments.

[89] FIG. 11 is an exploded perspective view showing a closure of a vessel according to the fifth embodiment of the present invention, FIG. 12 is a perspective view showing the inside of the vessel according to the fifth embodiment of the present invention, FIG. 13 is a sectional view showing a state that the closure of a vessel is mounted on a vessel inlet according to the fifth embodiment of the present invention, and FIG. 14 is a sectional view showing a state that the closure of a vessel is inserted into the vessel inlet according to the fifth embodiment of the present invention.

[90] The closure of a vessel according to the fifth embodiment is a kind of closure for protecting a child, and has a structure that the supplementary closure aforementioned in the first embodiment is coupled to a CRC.

[91] The closure of a vessel 100 according to the fifth embodiment may comprise an inner cap 120 mounted at a vessel inlet 10 through which contents stored in a vessel 500 is discharged out; an outer cap 110 disposed on an outer circumferential surface of the inner cap 120 so that the outer cap 110 idles around the inner cap 120; a rotation force transmitting portion formedbetween the inner cap 120 and the outer cap 110, for transmitting a rotation force of the outer cap 110 to the inner cap 120 when the outer cap 110 is downwardly moved by a force more than a certain degree; and a supplementary closure 200 mounted within the inner cap 120, etc.

[92] The vessel 50 stores therein not only liquid such as water, whisky and soju, but also poisonous drug, detergent, home drug, etc. that may cause harm damage to a child.

[93] The outer cap 110 may be formed ina cylindrical shape, and a plurality of convex- concave protrusions 128 for facilitating a user to rotate the outer cap 110 by grasping may be formed on an outer circumferential surface thereof. A separation preventing protrusion 129 for preventing the inner cap 120 from being separated from the outer cap 110 may be formed at a lower inner circumferential surface of the outer cap 110.

[94] The inner cap 120 is formed as a cylindricalshape so as to be rotatably inserted into the outer cap 110, and a female screw portion 112 screw-coupled to a male screw portion 13 formed on an outer circumferential surface of the vessel inlet 10 is formed on an inner circumferential surface of the inner cap 120.

[95] The rotation force transmitting portion includesfirst keys 111 formed on an outer circumferential surface of the inner cap 110 in a circumferential direction, and second keys 121 gear-engaged with the first keys 111 and formed on an inner circumferential surface of the outer cap in a circumferential direction.

[96] A receiving groove 113 for receiving a sealing portion 220 of the supplementary closure 200 to be explained later is formed at an uppest end of an inner circumferential surface of the inner cap 120, and a receiving groove 101 for fitting a supporting portion 210 of the supplementary closure 200 is formed at a lowest end of the inner circumferential surface of the inner cap 120.

[97] The inner cap 120 and the outer cap 110 are configured so that they can be rotated together in a closing direction, they may idle around each other in opening direction, and they may be rotated together when the outer cap 110 is pressed towards the inner cap 120.

[98] One of the inner cap 120 and the outer cap 110 may be provided with a distance maintaining member 290 for maintaining a certain distance between the first keys 111 and the second keys 121 so that the first and the second keys 111, 121 can not be gear- engaged with each other when the outer cap 110 is not pressed, but can be gear- engaged with each other when the outer cap 110 is pressed.

[99] The distance maintaining member 290 may be formed at a lower surface of an upper end of the outer cap 110 so as to be easily bent. Here, an inclined surface 291 may be formed at an upper end of the inner cap 120 in a direction that the distance maintaining member 290 is bent so that the distance maintaining member 290 may be easily bent.

Also, at an inner circumferential surface of the outer cap 120, there may be formed a second inclined protrusion 270 for idling the outer cap 110 with respect to the inner cap 120 by sliding on the inclined surface 281 in an opening direction, and for transmitting a rotation force of the outer cap 110 to the inner cap 120 by being locked by the jaw 282 in a closing direction. The second inclined protrusion 270 may be provided with an inclined surface 271 in a closing direction, and a jaw 272 in an opening direction in correspondence to the first inclined protrusion 280.

[102] A protrusion 117 may be formed at a lower end of the inner cap 120 so as to be protruding outwardly so that the first and the second inclined protrusions 280, 270 have a certain gap therebetween.

[103] The supplementary closure 200 includes a supporting portion 210 inserted into the receiving groove 101 of the inner cap 120; a sealing portion 220 connected to an upper end of the supporting portion 210 for sealing the vessel inlet 10; and a skirt portion 230 connected to a lower end of the supporting portion 210 and locked by an outer circumferential surface of the vessel inlet 10, for checking whether the closure of a vessel 100 has been opened from the vessel inlet 10.

[104] The supporting portion 210 is formed in a cylindrical shape, and has a plurality of connection ribs 224, 233 at upper and lower ends thereof with a certain interval. The connection ribs 224, 233 include a first connection rib 224 protruding toward an upper side of the supporting portion 210 thus to be connected to an outer circumferential surface of the sealing portion 220, and a second connection rib 233 protruding toward a lower side of the supporting portion 210 thus to be connected to an upper end of the skirt portion 233.

[105] The connection ribs 224, 233 are formed as thin films and are when a certain force is applied thereto, thereby respectively separating an upper end of the supporting portion 210 and the sealing portion 220 from each other, and separating a lower end of the supporting portion 210 and the skirt portion 230 from each other.

[106] An outer circumferential surface of the sealing portion 220 is connected to an upper end of the supporting portion 210 by the first connection rib 224. An edge of the sealing portion 220 is closely contacted to an upper end of the vessel inlet 10, and is inserted and coupled to the receiving groove 113 formed at the inner cap 120. and A central portion 221 of the sealing portion 220 having a disc shape has a height lower than that of the edge portion, thereby being inserted into the vessel inlet 10.

[107] When the closure of a vessel 100 is mounted at the vessel inlet 10, the sealing portion 220 is separated from the supporting portion 210, and then is mounted at the receiving groove 113 formed at the closure of a vessel 100 thus to maintain a fixed state to the closure of a vessel 100.

[108] The skirt portion 230 is formed ina cylindrical shape, and is detachably connected to a lower end of the supporting portion 210 by the second connection rib 233. A locking groove 237 for locking a locking protrusion 236 formed at the vessel inlet 10 is formed at an inner surface of the skirt portion 230.

[109] An operation of the closure of a vessel will be explained in more detail with reference to the attached drawings.

[110] FIG. 15 is a sectional view showing a state that the closure of a vessel is separated from the vessel inlet according to the fifth embodiment of the present invention.

[I l l] When the closure of a vessel is not operated, contents stored in the vessel 500 is not discharge out. However, when the closure of a vessel is mounted at the vessel inlet 10, the first keys 111 formed at the outer cap 110 are separated from the second keys 121 formed at the inner cap 120 by the distance maintaining member 290, thereby not transmitting a rotation force of the outer cap 110 to the inner cap 120.

[112] When a user is to separate the closure of a vessel 100 from the vessel inlet 10 by rotating the outer cap 110, the outer cap 110 is pressurized downwardly. As a result, the distance maintaining member 290 is elastically deformed, and thus the first and the second keys 111, 121 are gear-engaged with each other in an opening direction. Accordingly, a rotation force of the outer cap 110 is transmitted to the inner cap 120.

[113] By the above process that the first and the second keys 111, 121 are gear-engaged with each other in an opening direction, the closure of a vessel 100 is separated from the vessel inlet 10 by the transfer of the rotation of the outer cap 120 the inner cap 110.

[114] Here, the supplementary closure of the fifth embodiment has the same operation as the supplementary closure of the second embodiment, and thus its detailed explanation will be omitted.

[115] The supplementary closure of the first embodiment may be applied to the CRC of the fifth embodiment.
