At this time, the first outlet 21 is not blocked by the wing portion 122 of the first opening and closing member 12 by the flow of air as described above, the second outlet 31 is the second opening and closing member 14 It is blocked by the wing 142 of. Therefore, when the piston 30 rises, external air flows into the pump chamber 11 only through the first discharge port 21.
따라서, 날개부(122,142)가 외측으로 갈수록 하방 경사를 가지면 상술한 바와 같은 날개부(122,142)의 작용이 보다 원활하게 이루어질 수 있다. Therefore, when the wing portions 122 and 142 have downward inclination toward the outside, the action of the wing portions 122 and 142 as described above may be more smoothly performed.

In addition, the case 20 may further include an extension 25 (see FIG. 6) extending from the outer circumferential surface thereof. The extension part 25 may be formed to be substantially the same as the length of the case protrusion part 24. However, the extension part 25 may be made shorter or longer than the length of the case protrusion part 24. The extension part 25 protects the packing member 70 from foreign matters.
패킹부재(70)는 병마개(10)가 병(1)에 장착시 병(1)에 삽입되어 병(1) 내부를 밀폐시키며, 중심부에 상기 제3배출구(71)가 구비되는 밀폐부(72)와, 상기 케이스돌출부(24)에 결합되는 결합홈(73)을 포함하여 이루어질 수 있다. 결합홈(70)으니 케이스돌출부(24)에 억지끼움 따위로 결합될 수 있다.The packing member 70 has a bottle cap 10 inserted into the bottle 1 to seal the inside of the bottle 1 when the bottle cap 10 is mounted on the bottle 1, and a sealing part 72 having the third discharge port 71 at the center thereof. ), And a coupling groove 73 coupled to the case protrusion 24. That is, the coupling groove 70 may be coupled to the case protrusion 24 by interference fit.
따라서, 본 발명에 따른 병마개(10)를 병(1)에 장착하면, 병(1) 내부는 밀폐부(72)에 의해 밀폐됨과 동시에 제3배출구(71)를 통해 제1배출구(21)와 연통될 수 있어서, 피스톤(30)의 반복적인 눌러짐에 의해 병(1) 내부의 공기가 펌프실(11)로 배출될 수 있다.Therefore, when the bottle cap 10 according to the present invention is mounted on the bottle 1, the inside of the bottle 1 is sealed by the sealing portion 72 and at the same time through the third discharge port 71 and the first discharge port 21. By communicating with the piston 30, the air inside the bottle 1 can be discharged into the pump chamber 11 by repeatedly pressing the piston 30.
상기 케이스돌출부(24)의 하단에는 병(1) 내부의 공기가 제3배출구(71)를 통해 제1배출구(21)로 원활하게 유입될 수 있도록 공기유로홈(26)이 형성될 수 있다. An air flow path groove 26 may be formed at a lower end of the case protrusion 24 so that air inside the bottle 1 may smoothly flow into the first outlet 21 through the third outlet 71.
한편, 본 발명의 일실시예에 따른 병마개(10)는 피스톤(30)을 하강시킨 상태에서 소정각도 회전시키면 제1이탈방지부재(40)에 걸림되어 피스톤(30)이 하강한 상태로 고정되도록 하는 고정부를 더 포함하여 이루어질 수 있다.On the other hand, the bottle cap 10 according to an embodiment of the present invention is caught by the first separation preventing member 40 when the piston 30 is rotated by a predetermined angle in the lowered state so that the piston 30 is fixed in the lowered state. It may be made by further comprising a fixing part.
상세히, 상기 고정부는 피스톤(30)의 외주면에 길이방향으로 형성되는 가이드돌기(38)와, 상기 가이드돌기(38)에 대응하도록 제1이탈방지부재(40)의 내주면에 형성되는 가이드홈(41)을 포함하여 이루어질 수 있다. 여기서, 상기 가이드돌기(38)의 길이는 피스톤(30)의 길이보다 짧게 즉, 피스톤(30)의 하단부로부터 상단부 소정부위까지 형성될 수 있다. In detail, the fixing part is a guide protrusion 38 formed in the longitudinal direction on the outer circumferential surface of the piston 30 and a guide groove 41 formed on the inner circumferential surface of the first release preventing member 40 to correspond to the guide protrusion 38. It can be made, including). Here, the length of the guide protrusion 38 may be formed shorter than the length of the piston 30, that is, from the lower end of the piston 30 to a predetermined portion of the upper end.
따라서, 피스톤(30)이 하강하는 경우에는 가이드돌기(38)가 가이드홈(41)을 따라 슬라이딩 되다가, 피스톤(30)이 끝까지 하강하게 되면 가이드돌기(38)의 상단부가 가이드홈(41) 아래에 위치하게 되므로, 그 상태에서 피스톤(30)을 회전시키면 가이드돌기(38)가 제1이탈방지부(40)에 걸림됨으로써, 피스톤(30)이 고정될 수 있다. Therefore, when the piston 30 descends, the guide protrusion 38 slides along the guide groove 41, and when the piston 30 descends to the end, the upper end of the guide protrusion 38 is below the guide groove 41. Since the piston 30 is rotated in the state, the guide protrusion 38 is caught by the first release preventing part 40, so that the piston 30 may be fixed.
한편, 본 발명의 일실시예에 따른 병마개(10)는 피스톤(30)이 하강하는 경우에 제1개폐부재(12)를 가압하여 제1배출구(21)에 압착시키는 제1개폐부재 가압부를 더 포함하여 이루어질 수 있다. On the other hand, the bottle cap 10 according to an embodiment of the present invention further presses the first opening and closing member pressurizing portion for pressing the first opening and closing member 12 to the first outlet 21 when the piston 30 is lowered. It can be made, including.
상세히, 상기 제1개폐부재 가압부는 피스톤(30)의 상부막(32)으로부터 하방으로 소정길이 연장되며, 중심부에 제2배출구(31)가 구비되는 가압돌출부(39)와, 피스톤(30)이 하강하는 경우에 상기 가압돌출부(39)에 의해 가압되어 제1개폐부재(12)를 압착하는 압착부재(80)를 포함하여 이루어질 수 있다.In detail, the first opening / closing member pressurizing portion extends downwardly from the upper film 32 of the piston 30, and the pressurizing protrusion 39 and the piston 30 are provided with a second outlet 31 at the center thereof. When descending, it may include a pressing member 80 that is pressed by the pressure protrusion 39 to compress the first opening and closing member 12.
따라서, 제1배출구(21)는 피스톤(30)이 하강하는 경우에 제1개폐부재(12)에 의해 더욱 견고하게 막힐 수 있다.Therefore, the first outlet 21 can be more firmly blocked by the first opening and closing member 12 when the piston 30 is lowered.
상기 제1개폐부재 가압부는 피스톤(30)이 하강한 상태로 고정될 수 있을 때까지 하강한 경우에 제1개폐부재(12)를 가압하여 제1배출구(21)를 압축하도록 구비될 수 있다. 이는 가압돌출부(39)와 압착부재(80)의 길이를 적절히 조절함으로써 이루어질 수 있다. The first opening and closing member pressing portion may be provided to compress the first outlet 21 by pressing the first opening and closing member 12 when the piston 30 is lowered until it can be fixed in the lowered state. This may be achieved by appropriately adjusting the length of the pressure protrusion 39 and the pressing member 80.
제1개폐부재 가압부는 피스톤(30)을 하강시키는 중에도 제1개폐부재(12)를 가압하여 제1배출구(21)를 압착하도록 구비될 수도 있지만, 이 경우 압착부재(80)가 빈번하게 제1개폐부재(12)를 압착하게 되므로 제1개폐부재(12)가 손상될 염려가 있어서 바람직하지 않기 때문이다.Although the first opening / closing member pressurizing portion may be provided to press the first opening / closing member 12 to press the first outlet 21 even while the piston 30 is lowered, in this case, the pressing member 80 is frequently used. Since the opening and closing member 12 is compressed, the first opening and closing member 12 may be damaged, which is undesirable.
또한, 본 발명에 따른 병마개(10)는 병(1)에 장착되어 병(1) 내부를 진공상태로 만든 후 병(1) 내부를 밀폐시키기 위한 것인데, 상술한 바와 같이 피스톤(30)을 하강시켜 고정시킨 경우에 제1개폐부재(12)가 제1배출구(21)를 압착한 상태가 된다면, 병(1) 내부로 외부 공기가 유입되는 통로는 제1배출구(21)이기 때문에, 병(1) 내부는 더욱 밀폐되어 오랜 시간동안 진공상태로 유지될 수 있어서, 바람직하다.In addition, the bottle cap 10 according to the present invention is to seal the inside of the bottle 1 after being mounted on the bottle 1 to make the inside of the bottle 1 in a vacuum state, and lowering the piston 30 as described above. If the first opening / closing member 12 is in a state in which the first outlet 21 is compressed, the passage through which external air flows into the bottle 1 is the first outlet 21, so that the bottle ( 1) It is preferable because the interior is more sealed and can be kept in a vacuum state for a long time.
한편, 상기 압착부재(80)는 제2이탈방지부재(50)의 중공홀(52)에 삽입되어 상하이동가능하게 케이스(20)에 장착될 수 있는데, 이 경우 중심부에는 중공홀(81)이 형성되며, 하부에는 길이방향으로 압착부재 공기유로부(82)가 형성될 수 있다. 이는 제1투입구(21)로 유입된 공기가 펌프실(11)로 원활하게 유입되도록 하기 위한 것이다. On the other hand, the pressing member 80 is inserted into the hollow hole 52 of the second separation preventing member 50 may be mounted to the case 20 so as to be movable shanghai, in this case the hollow hole 81 in the center It is formed, the lower portion may be formed in the pressing member air flow path 82 in the longitudinal direction. This is to allow the air introduced into the first inlet 21 to flow smoothly into the pump chamber 11.
상기 압착부재(80)의 끝단에는 제1개폐부재(12)의 날개부(122)에 대응하도록 내측으로 갈수록 상방 경사를 가지는 경사부(83)가 형성될 수 있다. An inclined portion 83 having an upward inclination toward the inner side of the pressing member 80 may be formed to correspond to the wing portion 122 of the first opening / closing member 12.
그러면, 압착부재(80)가 제1개폐부재(12)의 날개부(122)를 압착하는 경우에 상기 날개부(122)의 손상을 방지할 수 있을 뿐만 아니라, 보다 효과적으로 날개부(122)를 압착할 수 있다.Then, when the crimping member 80 compresses the wing 122 of the first opening / closing member 12, not only can the damage of the wing 122 be prevented, but also the wing 122 can be more effectively It can be compressed.
도 5는 본 발명에 따른 제1개폐부재 가압부의 다른 실시예를 나타내는 도면이다. 5 is a view showing another embodiment of the first opening and closing member pressing unit according to the present invention.
도 5를 참조하면, 본 실시예에 따른 제1개폐부재 가압부는 상기 실시예와 비교하여 피스톤(30)을 하강시킨 후 제1이탈방지부재(40)에 걸림되도록 회전시키면 압착부재(80)를 소정거리 하향 이동시키는 캠부로 형성될 수 있다. Referring to FIG. 5, the first opening / closing member pressurizing unit according to the present embodiment lowers the piston 30 and then rotates the first release preventing member 40 so as to be engaged with the first release preventing member 40. It may be formed of a cam portion for moving downward a predetermined distance.
상세히, 상기 캠부는 가압돌출부(39)의 하단부에 형성되는 제1캠부(391)와, 상기 제1캠부(391)에 대응하도록 압착부재(80)의 상단부에 형성되는 제2캠부(84)를 포함하여 이루어질 수 있다.In detail, the cam portion may include a first cam portion 391 formed at the lower end of the pressurizing protrusion 39 and a second cam portion 84 formed at the upper end of the pressing member 80 to correspond to the first cam portion 391. It can be made, including.
따라서, 본 실시예에 따르면, 피스톤(30)을 하강시킨 후 소정각도 회전시켜 제1이탈방지부(40)에 걸림되도록하여 고정시키는 경우에, 가압돌출부(30)가 압착부재(80)를 더욱 가압하게 되어, 제1개폐부재(12)는 압착부재(80)에 의해 더욱 압착될 수 있으며, 그에 따라 제1배출구(21)는 더욱 밀폐될 수 있다. Therefore, according to the present embodiment, when the piston 30 is lowered and rotated by a predetermined angle so as to be locked to the first release preventing part 40 so as to be fixed, the pressure protrusion part 30 further presses the crimping member 80. By pressing, the first opening / closing member 12 may be further compressed by the pressing member 80, and thus the first outlet 21 may be further sealed.
한편, 도면에는 도시되지 않지만, 본 발명에 따른 제1개폐부재 가압부는 상기 실시예에서와 같이 가압돌출부(39)와 압착부재(80)로 이루어지지 않고, 케이스(20)의 하부막(22)과 제2이탈방지부재(50) 사이에 구비되어 피스톤(30)이 하강하는 경우에 제1개폐부재(12)를 압착하는 탄성부재를 포함하여 이루어질 수도 있다. On the other hand, although not shown in the drawings, the first opening and closing member pressing portion according to the present invention is not made of the pressing projection portion 39 and the pressing member 80 as in the above embodiment, the lower film 22 of the case 20 It may be provided between the second separation preventing member 50 and the elastic member for pressing the first opening and closing member 12 when the piston 30 is lowered.
이하, 본 발명의 일실시예에 따른 병마개(10)의 작동을 도3 및 도4를 참조하여 개략적으로 설명한다.Hereinafter, the operation of the cap 10 according to an embodiment of the present invention will be schematically described with reference to FIGS.
도 3에서 보이는 바와 같이, 사용자가 피스톤(30)을 눌러주어 피스톤(30)이 하강하는 경우에는 피스톤(30)과 케이스(20)가 이루는 펌프실(11)의 공간이 줄어들게 된다. As shown in FIG. 3, when the user pushes the piston 30 and the piston 30 descends, the space of the pump chamber 11 formed by the piston 30 and the case 20 is reduced.
이때, 펌프실(11) 내에 존재하는 공기는 제1배출구(21) 또는 제2배출구(31)를 통해 외부로 배출되어야 하는데, 도 3에서 보이는 바와 같이, 이 경우 제1배출구(21)는 제1개폐부재(12)에 의해 막히게 되므로, 펌프실(11) 내에 존재하는 공기는 제2배출구(31)를 통해 외부로 배출된다.At this time, the air present in the pump chamber 11 should be discharged to the outside through the first outlet 21 or the second outlet 31, as shown in Figure 3, in this case the first outlet 21 is the first Since it is blocked by the opening and closing member 12, the air present in the pump chamber 11 is discharged to the outside through the second discharge port (31).
또한, 도 4에서 보이는 바와 같이, 사용자가 피스톤(30)을 눌러주지 않으면, 피스톤(30)은 탄성부재(17)의 탄성력에 의해 다시 상승하게 되면서 펌프실(11)의 공간이 다시 늘어나게 된다.In addition, as shown in Figure 4, if the user does not press the piston 30, the piston 30 is raised again by the elastic force of the elastic member 17, the space of the pump chamber 11 is increased again.
이때, 상기 펌프실(11)에는 공기가 존재하지 않는 진공상태이므로 상기 펌프실(11) 내부로 외부의 공기가 유입되어야 하는데, 도 4에서 보이는 바와 같이, 이 경우 제2배출구(31)는 제2개폐부재(14)에 의해 막히게 되므로, 병(1) 내부의 공기가 제3배출구(71)와 제1배출구(21)를 통해 펌프실(11) 내로 유입된다.At this time, since the air does not exist in the pump chamber 11, the outside air should be introduced into the pump chamber 11. As shown in FIG. 4, in this case, the second outlet 31 is opened and closed. Since it is blocked by the member 14, the air inside the bottle 1 flows into the pump chamber 11 through the 3rd discharge port 71 and the 1st discharge port 21. As shown in FIG.
그리고, 사용자가 다시 피스톤(30)을 눌러주면, 제1배출구(21)를 통해 펌프실(11)로 유입된 병(1) 내부의 공기는 외부로 배출되게 된다.When the user presses the piston 30 again, the air inside the bottle 1 introduced into the pump chamber 11 through the first outlet 21 is discharged to the outside.
따라서, 사용자가 피스톤(30)을 반복해서 눌러주면, 병(1) 내부의 모든 공기는 펌프실(11)을 통해 외부로 배출되며, 그에 따라 병(1) 내부는 진공상태가 될 수 있다.Therefore, when the user repeatedly presses the piston 30, all the air inside the bottle 1 is discharged to the outside through the pump chamber 11, and thus the inside of the bottle 1 may be in a vacuum state.
이후, 사용자는 피스톤(30)을 하강시켜 소정각도 회전시킴으로써 제1이탈방지부재(40)에 걸림되도록 하여 고정시킨다. 이 경우, 제1배출구(21)는 제1개폐부재(12)에 의해 압착된 상태가 되므로 병(1) 내부는 완전히 밀폐될 수 있다. 나아가 압착부재(80)는 날개부(122)를 압착하고 있으므로, 날개부(122)와 접촉하는 면에 스크래치가 있더라도 병(1) 내부로 최대한 공기가 들어가지 않도록 한다. Thereafter, the user lowers the piston 30 and rotates the predetermined angle so as to be locked to the first release preventing member 40. In this case, since the first outlet 21 is compressed by the first opening / closing member 12, the inside of the bottle 1 may be completely sealed. Furthermore, since the crimping member 80 is crimping the wing 122, even if there is a scratch on the surface in contact with the wing 122 so that air does not enter the bottle 1 as much as possible.
상술한 바와 같은 구성을 가지는 본 실시예에 따른 병마개(10)는 와인병에 매우 유용하게 사용될 수 있다. Bottle cap 10 according to the present embodiment having the configuration as described above can be used very usefully for wine bottles.
일반적으로, 와인이 남은 와인병을 패킹과 같은 병마개로 막아 내부를 밀폐시킨 상태로 보관하게 되는데, 이 경우에도 와인병 내부에는 공기가 존재하게 되므로 와인의 맛과 향기가 변질될 염려가 있는데, 본 실시예에 따른 병마개(10)를 사용하여 와인병에 존재하는 공기를 모두 외부로 배출하여 진공상태로 만든 후에 와인병 내부를 완전히 밀폐시킨다면 그만큼 와인의 맛과 향기가 유지될 수 있기 때문이다.In general, the wine bottle left the wine bottle is sealed with a bottle cap such as packing to keep the inside sealed, even in this case there is a risk that the taste and aroma of the wine because the air is present inside the wine bottle. This is because if the bottle cap 10 according to the embodiment discharges all the air present in the wine bottle to the outside to make a vacuum state and then completely seals the inside of the wine bottle, the taste and aroma of the wine can be maintained.
