[58] Hereinafter, a closure of a vessel according to a first embodiment of the present invention will be explained in more detail with reference to FIGS. 1 to 8.

[59] The closure of a vessel according to a first embodiment of the present invention comprises a body 10 mounted to an inlet 2A of a vessel 2, the body 10 having a cover portion 12 covering the inlet 2A of the vessel 2, and a breakable portion 11 at the cover portion 12; and a plug 30 coupled to the body 10 so as to form an accommodation space (Sl) with the cover portion 12 of the body 10, for breaking the breakable portion 11 by pressing the breakable portion 11 of the body 10.

[60] Contents (P) in the form of liquid, powder, and grain may be stored in the accommodation space (Sl).

[61] The breakable portion 11 of the body 10 may be implemented in any forms to be broken by a pressing force of the plug 30. As shown in the preferred embodiment of the present invention, the breakable portion 11 of the body 10 may be simply implemented as at least one cutting line. The cutting line of the breakable portion 11 may be formed in a ring shape so as to be broken like a hole, or may be formed in a line shape such as a straight line or a curved line so that the cover portion of the body 10 can be widened along the breakable portion 11. Also, the cutting line may be formed to have a combined type between the ring shape and the line shape.

[62] More concretely, as shown in FIG. 8, the cutting line of the breakable portion 11 may include a ring portion 1 IA having a ring shape and formed at a part of the cover portion of the body 10, and a plurality of line portions 1 IB having line shapes and extending from the ring portion 1 IA to the edge of the cover portion 12 of the body 10. Since the cover portion 12 of the body 10 can be widened by a pressing force of the plug 30 and can be breakable into pieces, the contents (P) inside the accommodation space (Sl) can be rapidly and wholly poured into the vessel 2. And, a part of the cover portion 12 of the body 10 (e.g., a part corresponding to the ring portion 1 IA) does not

fall into the vessel 2.

[63] In order to uniformly transmit a pressing force of the plug 30 to the cover portion 12 of the body 10, the ring portion 1 IA is preferably disposed in correspondence to a pressing center of the plug 30.

[64] The body 10 may be composed of a body portion 14 detachably fitted into the inlet

2A of the vessel 2; and a body supporting portion 16 connected to the body portion 14 and inserted into the inlet 2A of the vessel 2, the body supporting portion 16 supporting the cover portion 12. Since the cover portion 12 of the body 10 is disposed in the vessel 2, the inlet 2A of the vessel 2 can be stably sealed, and the contents (P) stored in the accommodation space (Sl) can be poured into the vessel 2 in a clean state.

[65] The cover portion 12 may be formed in a flat plate shape, or a shape inclined toward a center, or a shape having upwardly bent edges shown in the preferred embodiment.

[66] The body portion 14 may be composed of a body portion body 14A coupled to the vessel 2 in a detachable manner using screws, and connected to the body supporting portion 16; and a body portion skirt portion 14B detachably coupled to the body portion body 14A and mounted to the vessel 2. Under this configuration, the body portion skirt portion 14B maintains a mounted state of the body portion 14 to the inlet 2A of the vessel 2. And once the body portion 14 is rotated, the body portion body 14A is easily separated from the vessel 2 while the body portion skirt portion 14B is plucked from the body portion body 14A. The body portion 14 may be coupled to the vessel 2 in various manners including a snap manner as well as a coupling manner using screws.

[67] The body supporting portion 16 may be formed in various shapes, especially, a ring shape, thereby allowing the accommodation space (Sl) to be easily formed. As the accommodation space (Sl) where the plug 30 inserted thereinto is moved is formed, the plug 30 may intensively press the breakable portion 11 of the body 10. And, the accommodation space (Sl) may maintain a sealed state.

[68] As the body supporting portion 16 is formed to be closely contacted to an inner surface of the vessel 2, the inlet 2A of the vessel 2 may be reliably sealed.

[69] Since the body supporting portion 16 is provided with one or more sealing portions

16A protruding from an outer surface of the body supporting portion 16 and closely contacted to an inner surface of the vessel 2, a sealed state of the inlet 2A of the vessel 2 may be enhanced. The sealing portions 16A may be implemented as ring-shaped protrusions.

[70] The plug 30 may be composed of a plug supporting portion 32 coupled to the body

10; and a plug pressing portion 34 detachably coupled to the plug supporting portion 32, and separated from the plug supporting portion 32 when receiving an external

force, for pressing the breakable portion 11 of the body 10.

[71] Once the plug pressing portion 34 fixed by the plug supporting portion 32 is pressed, the plug pressing portion 34 is separated from the plug supporting portion 32. Then, the plug pressing portion 34 moves to press the breakable portion 11 of the body 10. Before being separated from the plug supporting portion 32, the movement of the plug pressing portion 34 may be limited. The plug supporting portion 34 may be stably coupled to the body 10 due to no motion, and may be coupled to the body 10 in various manners.

[72] The plug 30 will be explained in more detail.

[73] The plug supporting portion 32 is formed in a ring shape so as to be fitted into outside of the body 10, and may be provided with one or more locking protrusions 32A protruding from an inner surface of the plug supporting portion 32 and closely contacted to the body 10. Accordingly, the plug supporting portion 32 may be easily and simply coupled to the body 10. In order to stably couple the plug supporting portion 32 and the body 10 to each other, the locking protrusions 32A of the plug supporting portion 32 may be formed in plurality in number along the circumference of the plug supporting portion 32. As the locking protrusions 32A of the plug supporting portion 32 are configured to be inserted into locking protrusion grooves 1OA formed on an outer surface of the body 10, a coupling force between the plug supporting portion 32 and the body 10 may be enhanced.

[74] The plug pressing portion 32 may be composed of a body 36 detachably coupled to the plug supporting portion 32, and forming the accommodation space (Sl) with the cover portion 12 of the body 10; and a pole 38 coupled to the body 36, and disposed between the body 36 and the breakable portion 11 of the body 10. The body 36 and the pole 38 may be integrally formed with each other. Under the construction of the body 36 and the pole 38, the accommodation space (Sl) may be easily formed, and positions of the pole 38 and the breakable portion 11 of the body 10 with respect to each other may be freely tuned.

[75] Since the body 36 is formed so as to cover the accommodation space (Sl), the accommodation space (Sl) may maintain a clean state. And, even if the breakable portion 11 of the body 10 is broken, a sealed state of the vessel 2 may be maintained before the closure is separated from the vessel 2.

[76] Since the body 36 is provided with one or more sealing portions 36A protruding from an outer surface of the body 36 and closely contacted to an inner surface of the body supporting portion 16, a sealed state of the accommodation space (Sl) and the inlet 2A of the vessel 2 may be enhanced. The sealing portions 36 A of the body 36 may be implemented as ring-shaped protrusions.

[77] The body 36 is formed such that an upper side surface 36' thereof has a smooth

surface without a concaved portion. This may allow the body 36 to be easily fabricated, and the plug 30 to be easily moved.

[78] Since the body 36 is formed to be protruding from the body 10 in a state that the plug pressing portion 34 is coupled to the plug supporting portion 32, the plug pressing portion 34 is easily moved.

[79] The body 36 may be formed such that its upper portion has a larger size towards a lower side, in a moving direction of the plug 30.

[80] One or more bridges 36B detachably connected to the plug supporting portion 32 are protruding from an outer surface of the body 36, thereby allowing the plug supporting portion 32 and the plug pressing portion 34 to be easily separated from each other. The bridge 36B is formed so as to be locked by the body 10 after the breakable portion 11 of the body 10 is broken. This may prevent the plug pressing portion 34 from falling into the vessel 2.

[81] The pole 38 may be formed in various shapes. In the preferred embodiment, the pole

38 is composed of a plurality of wings 38' extending from the center of the pole 38, such that the breakable portion 11 of the body 10 is uniformly breakable. In order to prevent each of the wings 38' of the pole 38 from matching the cutting line of the breakable portion 11 of the body 10, the number of the wings 38' of the pole 38 is set to be different from the number of the cutting line of the breakable portion 11 of the body 10, especially, the number of the line portions 1 IB. More preferably, the number of the wings 38' of the pole 38 is set to be more than the number of the line portions 1 IB. That is, when the line portions 1 IB of the breakable portion 11 of the body 10 are implemented in three, the pole 38 may be formed in a cross shape so as to have four wings 38'.

[82] The closure of the vessel may further comprise a protection closure 40 detachably mounted to an outside of the plug 30. The protection closure 40 prevents the plug 30 from being unintentionally pressed. As the plug 30 is protected in a clean state, external materials are prevented from being introduced into the accommodation space (Sl) and the vessel 2. In order to maintain a state that the protection closure 40 covers the plug 30, the protection closure 40 may be provided with one or more protection closure protrusions 42 locked by the plug 30.

[83] Hereinafter, will be explained a process for pouring the contents (P) stored in the accommodation space (Sl) into the vessel 2, in a state that the closure is mounted to the vessel 2 according to the first embodiment of the present invention.

[84] As shown in FIG. 3, the plug 30 is pressed after the supplementary closure 40 is separated from the plug 30. Then, as shown in FIG. 4, the plug supporting portion 32 and the plug pressing portion 34 are separated from each other by the pressing force of the plug 30. Then, the plug pressing portion 34 presses the breakable portion 11 of the

body 10. As the breakable portion 11 of the body 10 is broken, the plug pressing portion 34 is moved into the accommodation space (Sl), and the contents inside the accommodation space (Sl) is poured into the vessel 2. Here, a sealed state of the vessel 2 is maintained by the plug pressing portion 34.

[85] In order to open the inlet 2A of the vessel 2, the body 10 is rotated as shown in FIG.

5. The body 14A and the skirt portion 14B are separated from each other, and then the body 10 is rotated to an upper side of the inlet 2A of the vessel 2. Accordingly, all the components except for the skirt portion 14B are separated from the vessel 2, and the inlet 2A of the vessel is opened.

[86] Hereinafter, a closure of a vessel according to a second embodiment of the present invention will be explained in more detail with reference to FIGS. 9 to 14.

[87] The second embodiment is the same as the first embodiment except for the plug pressing portion. Accordingly, the same reference numerals as those of the first embodiment will be used in the second embodiment, and only the plug pressing portion will be explained.

[88] Differently from the first embodiment, a plug pressing portion 134 is composed of a body 136 and a pole 138 formed to be detachable from each other.

[89] The plug pressing portion 134 may be configured such that a supplementary space

(S2) is formed between the body 136 and the pole 138. Accordingly, a preservative to prevent spoilage of the contents (P) stored in the accommodation space (Sl) so as to be poured into the vessel 2, a dehumidifier to dehumidify the contents (P), etc. may be put into the supplementary space (S2).

[90] The plug pressing portion 134 may be also configured such that an air passage 100 through which the supplementary space (S2) and the accommodation space (Sl) are communicated with each other is formed between the body 136 and the pole 138. Since air inside the supplementary space (S2) and air inside the accommodation space (Sl) circulate through the air passage 100, the contents (P) stored in the accommodation space (Sl) can be safely protected by the preservative or the de- humidifier inside the supplementary space (S2).

[91] The plug pressing portion 134 may be also configured such that the air passage 100 is blocked when the plug pressing portion 134 is moved to press the breakable portion 11 of the body 10. This prevents the preservative or the dehumidifier inside the supplementary space (S2) from flowing into the vessel 2.

[92] The body 136 is formed to have the supplementary space (S2), and is formed such that a lower side surface of the supplementary space (S2) is opened for coupling with the pole 138.

[93] The pole 138 may be composed of a pole portion 140 for pressing the breakable portion 11 of the body 10; and a pole connection portion 150 disposed between the

pole portion 140 and the body 136, and movably coupled to the body 136.

[94] The pole connection portion 150 may be composed of a core portion 152 inserted into the body 136, and an edge portion 154 protruding from an outer surface of the core portion 152.

[95] The core portion 152 may be formed to have a size large enough to contact an inner surface of the body 136. One or more air passage grooves 152A may be formed on an outer surface of the core portion 152 such that the air passage 100 is formed.

[96] The edge portion 154 is disposed outside the body 136 and is formed to have a size enough to interfere with the body 136, such that the pole connection portion 150 is movable with the body 136.

[97] The edge portion 154 may be formed in a ring shape so as to block the air passage

100 when interferred with the body 136. When the plug pressing portion 134 is moved to press the breakable portion 11 of the body 10, the edge portion 154 serves as a blocking portion to block the air passage 100. Here, the blocking portion may be provided at the body 136.

[98] Preferably, the edge portion 154 is formed so as to block the air passage 100 by contacting the end of the body 136. In order to completely block the air passage 100, a sealing member formed of silicon may be further provided at the edge portion 154.

[99] Hereinafter, will be explained a process for mounting the closure to the vessel according to the second embodiment of the present invention.

[100] Firstly, the body 10 is mounted to the vessel 2, and the contents (P) poured into the vessel 2 are put into the accommodation space (Sl). Then, the pole 138 of the plug 130 is inserted into the body 10, precisely, the body supporting portion 16. Then, a preservative, a dehumidifier, etc. are put into the body 136 of the plug 130, precisely, the supplementary space (S2), and the plug supporting portion 32 and the body 136 integrally formed with each other are mounted to the vessel 2.

[101] As shown in FIG. 9, a part of the pole 138 of the plug 30 is inserted into the body

136. More specifically, the pole connection portion 150 of the pole 138, precisely, the core portion 152 is inserted into the supplementary space (S2). Here, the edge portion 154 of the pole connection portion 150 is spacing from the body 136 by a predetermined gap (hereinafter, will be referred to as 'air passage gap' G). Since the body 136 is coupled to the plug supporting portion 32 to be supported by the plug supporting portion 32, the pole 138 is supported by the cover portion 12 of the body 10 in a state that the breakable portion 11 of the body 10 is not broken, a frictional force is formed between the pole connection portion 150 and the body 136 in a state that the core portion 152 of the pole connection portion 150 contacts an inner surface of the body 136, the air passage gap (G) is maintained .

[102] Finally, the supplementary closure 40 is mounted to the vessel 2.

[103] Once the closure is mounted to the vessel 2, the vessel 2 maintains a sealed state.

And, air inside the accommodation space (Sl) and air inside the supplementary space (S2) circulate through the air passage gap (G) and the air passage 100.

[104] Hereinafter, will be explained a process for pouring the contents (P) inside the accommodation space (Sl) into the vessel 2 in a state that the closure has been mounted to the vessel 2.

[105] As shown in FIG. 10, once the plug 30 is pressed after the supplementary closure 40 is separated from the plug 30, the plug supporting portion 32 and the body 136 of the plug pressing portion 134 are separated from each other by the pressing force of the plug 30. Then, the body 136 is moved into the accommodation space (Sl). When the body 136 is moved by the air passage gap (G), the body 136 is closely contacted to the edge portion 154 of the pole 138 to block the air passage 100.

[106] Under this state, when the plug 30 is continuously pressed, the body 136 closely contacted to the edge portion 154 of the pole 138 as shown in FIG. 11 presses the pole 138, and the pole 138 presses the breakable portion 11 of the body 10. Accordingly, while the breakable portion 11 of the body 10 is broken, the contents (P) inside the accommodation space (Sl) are poured into the vessel (S).

[107] Hereinafter, a closure of a vessel according to a third embodiment of the present invention will be explained in more detail with reference to FIGS. 15 to 18.

[108] The third embodiment is the same as the first embodiment except for the plug and the supplementary closure. Accordingly, the same reference numerals as those of the first embodiment will be used in the third embodiment, and only the plug and the supplementary closure will be explained.

[109] The closure of the vessel according to the third embodiment of the present invention comprises a body 210 having a breakable portion 211 and a cover portion 212, and a plug 230 forming an accommodation space (Sl) with the cover portion 212 of the body 210.

[110] Like in the first embodiment, the body 210 may be provided with a skirt portion. However, the body 210 may not be provided with the skirt portion in the third embodiment.

[I l l] The plug 230 may be composed of a plug pressing portion 234 directly coupled to the body 210 so as to be movable.

[112] At one of the plug pressing portion 234 of the plug 230 and the body 210, may be formed with an interference protrusion 300 such that the plug pressing portion 234 locked by the body 210 with interference is movable when receiving an external force.

[113] More concretely, as shown in FIG. 16, once the closure of the vessel has been assembled, a protrusion 302 of the interference protrusion 300 is inserted into a groove 304. This may allow the plug pressing portion 234 to be restricted by the body 210 due

to the interference protrusion 300.

[114] As shown in FIG. 18, once the plug 230 is pressed, the protrusion 302 of the interference protrusion 300 is drawn out of the groove 304. Accordingly, the restricted state of the plug 230 is released, and the contents (P) are poured into the vessel 202.

[115] The interference protrusion 300 may be composed of a protrusion 302 protruding from an outer circumferential surface of the plug pressing portion 234, and a groove 304 formed on an inner circumferential surface of the body 210 for inserting the protrusion 302 therein.

[116] As another embodiment of the interference protrusion 300, the groove 304 may be formed at the plug pressing portion 234, and the protrusion 302 may be formed at the body 210. As still another embodiment, the protrusion 302 may be formed at both the plug pressing portion 234 and the body 210. The interference protrusion 300 may be formed in various manners without limitation to the above embodiments.

[117] The closure of the vessel may further comprise a protection closure 260 disposed to cover the plug 230 and the body 210 for protection.

[118] At at least one of the supplementary closure 260, the body 210, and the plug 230, may be formed with a closure interference protrusion 310 such that the supplementary closure 260 is prevented from being separated from the body 210.

[119] Preferably, the closure interference protrusion 310 may be formed at the protection closure 260 to cause interference with the body 210.

[120] The protection closure 260 may be formed such that one or more parts thereof corresponding to the closure interference protrusion 310 are cut, so as to be easily separated from the body 210.

[121] Preferably, the protection closure 260 may be provided with at least one pair of cutting lines 262 along a circumferential direction thereof such that only a part of the circumference thereof can be cut. As indicated by the dotted lines in FIGS. 15 and 16, a cutout portion 260A of the protection closure 260 cut by the cutting lines 262 may maintain a connected state to the other portion 260B of the protection closure 260 when being cut out. The cutout portion 260A of the protection closure 260 may be cut toward an upper side from a lower side as shown in this embodiment, or may be cut toward a lower side from an upper side as shown in other embodiment. As still another embodiment, the cutout portion 260A of the protection closure 260 may be cut toward an upper side from a lower side, or toward a lower side from an upper side, to be completely detached from the other portion 260B of the protection closure 260.

[122] The protection closure 260 may further include a handgrip 260C extending from the cutout portion 260A such that the cutout portion 260A is more easily cut out.

[123] The cutout portion 260A of the protection closure 260 may be cut out in the snap manner of the body 110 of the second embodiment.

It will also be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
