본 발명은 진공밸브 작동식의 밀폐용기에 관한 것이다.The present invention relates to a closed container of a vacuum valve operation.

일반적으로 용기본체에 뚜껑을 덮어 내용물을 밀봉 보관하는 밀폐용기로는 용기뚜껑에 패킹을 장착하여 뚜껑을 장착시 그 패킹이 용기본체의 테두리에 감합하여 틈새를 밀봉하게 하는 방식이 사용되고 있으며, 이에 덧붙여 뚜껑의 밀봉 체결력을 확보하기 위해 잠금날개를 구비한 밀폐용기가 많이 사용되고 있다.In general, as a sealed container that covers the container body and seals the contents, the packing is mounted on the container lid and the packing is fitted to the edge of the container body to seal the gap. In order to secure the sealing fastening force of the lid, a closed container with a locking wing is widely used.

그러나 단순히 뚜껑을 용기본체에 덮어 씌워 밀봉토록 하는 방식의 경우 밀폐력이 약하다는 문제가 있고, 잠금날개에 의한 체결 방식의 경우 뚜껑의 밀봉력은 우수하나 잠금날개를 열고 닫는 동작을 반복하여야 하므로 사용상에 있어 불편하다는 문제가 지적되고 있다.However, there is a problem that the sealing force is weak in the case of simply covering the lid on the container body to seal, and in the case of the fastening method by the lock wing, the sealing force of the lid is excellent, but the operation of opening and closing the lock wing must be repeated. Problem is pointed out.

이때문에 도 6에 도시하는 것과 같이 용기뚜껑(30)에 진공밸브(31)를 설치하고, 패킹(32)이 장착된 용기뚜껑(30)을 용기본체(33)에 덮어 장착한 상태에서 용기뚜껑(30)을 위해서 내리 눌러 용기내의 체적 감소분만큼의 공기를 진공밸브(31)를 통해 외부로 배출되도록 한 후 진공밸브(31)를 내리눌러 밸브시트(37)에 밀착하여 내외부의 연통 상태를 차단하게 되면 용기뚜껑에 벗김력이 작용하더라도 진공밸 브(31)가 용기 뚜껑의 밸브공(34)을 차단하고 있어 용기내에 진공압이 형성되는 것에 의해 용기뚜껑(30)이 벗겨지지 않도록 작용하며, 용기뚜껑(30)을 벗겨낼 때에는 진공밸브(31)를 밸브시트(37)로부터 들어올려 밸브공(34)을 통해 용기내외를 연통시키므로써 용기 뚜껑(30)이 아무런 저항없이 쉽게 벗겨지도록 한 진공밸브 작동식의 밀폐 용기를 제안되어 사용중에 있다.For this reason, as shown in FIG. 6, the vacuum valve 31 is installed in the container lid 30, and the container in which the container lid 30 with the packing 32 is covered with the container main body 33 is mounted. Press down for the cap 30 to allow the volume reduction in the container to be discharged to the outside through the vacuum valve 31, and then press down the vacuum valve 31 to closely contact the valve seat 37 to maintain internal and external communication. When it is blocked, even if peeling force acts on the container lid, the vacuum valve 31 blocks the valve hole 34 of the container lid, so that the vacuum lid is formed in the container so that the container lid 30 does not peel off. When the container lid 30 is peeled off, the vacuum valve 31 is lifted from the valve seat 37 to communicate with the inside and outside of the container through the valve hole 34 so that the container lid 30 can be easily peeled off without any resistance. Vacuum valve-operated sealed container is proposed have.

한편, 용기 뚜껑의 개폐 장착의 편의성 증진만이 아니고, 음식물을 장기간 보관할 목적이라면 용기 내부의 공기를 완전히 빼내어 진공화시키는 것이 바람직한데, 이 경우 용기뚜껑(30)을 내리 누르는 정도로는 용기뚜껑 표면의 변형에 따른 용기내용적의 감소분만큼만 공기가 진공밸브(31)를 통해 외부로 배출되므로 전체 용기 체적 대비 용기 내용적의 변화가 미미하여 용기체적만큼의 공기가 그대로 들어 있는 상태이므로 용기뚜껑(30)의 벗겨짐을 방지하는데에는 유효하나 음식물의 보관에는 용기내의 공기가 음식물에 영향을 주기 때문에 장기 보관에 별 도움이 되지 않는다는 점이 지적되고 있다.On the other hand, not only to increase the convenience of opening and closing the container lid, if the purpose of storing food for a long time it is desirable to completely evacuate the air inside the container, in this case deformed the surface of the container lid to the extent that the container lid 30 is pressed down Since the air is discharged to the outside through the vacuum valve 31 only by the reduction of the container content according to the present invention, the change in the container content is insignificant compared to the entire container volume, and thus the container volume 30 is kept intact, thus preventing the container lid 30 from being peeled off. It is pointed out that food storage is not helpful for long-term storage because the air in the container affects the food.

이때문에 진공펌프(35)를 사용하여 용기내의 모든 공기를 강제로 흡인하여 외부로 배출토록 하고 있는데, 이와같이 진공펌프(35)에 의한 강제 공기 배출의 경우 용기 내부에 잔존하는 공기가 거의 없게 되어 음식물을 장시간 보관시 부패 진행 속도가 크게 더더지는 장점이 있어 음식물을 부패로 부터 안전하게 보관할 수 있게 된다.For this reason, the vacuum pump 35 is used to force all air in the container to be sucked out and discharged to the outside. Thus, in the case of forced air discharge by the vacuum pump 35, there is almost no air remaining inside the container. When the food is stored for a long time, the decay speed is greatly increased, so that food can be stored safely from the decay.

그런데 상기한 진공펌프(35)에 의해 용기 내부의 공기를 외부로 배출하고자 하면 도 6에 도시한 것과 같이 마치 흡반처럼 생긴 접속부(36)로 진공밸브(31)의 전체 외주를 감싸도록 하여야 하므로써 접속부(36)가 지나치게 커져야 하며, 용기 뚜껑의 주변 구성의 상황에 따라서는 접속부(36)의 장착 연결이 제한될 수 밖에 없는 문제가 있어 진공펌프의 컴팩트화가 곤란하여 보관이 불편하고, 실리콘고무 흡반인 접속부(36)가 너무 커서 쉽게 파손될 우려가 있었다.However, when the air inside the container is discharged to the outside by the vacuum pump 35, the connection part must be wrapped around the entire outer circumference of the vacuum valve 31 by the connection part 36, which looks like a sucker as shown in FIG. (36) should be too large, there is a problem that the mounting connection of the connection portion 36 is limited depending on the circumstances of the peripheral configuration of the container lid, it is difficult to compact the vacuum pump, the storage is inconvenient, and the silicone rubber sucker There was a fear that the connection part 36 was too large and easily broken.

이에 본 발명은 상기한 점을 감안하여 제안한 것으로서 그의 목적으로 하는 것은 용기 내부를 진공상태로 밀폐시켜 뚜껑의 장착력을 확보함과 함께 진공펌프를 접속하여 용기 내부의 공기를 외부로 배출시켜 용기 내부를 진공화하여 음식물을 부패 없이 장기간 보관이 가능토록 하되, 진공펌프의 접속부가 컴팩트해져 보관이 간편하고 파손 우려가 없도록 진공밸브를 이중 구조화한 밀폐 용기를 제공하는데 있다.Accordingly, the present invention has been proposed in view of the above point, and its object is to seal the inside of the container in a vacuum state to secure the capping force of the lid and to connect the vacuum pump to discharge the air inside the container to the outside to the inside of the container. By vacuuming the food to be stored for a long time without corruption, but the compact connection portion of the vacuum pump is easy to store and provides a sealed container with a double structure of the vacuum valve so that there is no fear of damage.

The valve head 18 which abuts on the step surface 15 which forms a seat, and the separation prevention head 19 formed in the lower end of the said valve shaft rod 17, The separation prevention head 19 is a diameter reduction part. When exposed to the hole extended through the inner diameter of (16) is caught on the lower end surface 20 is not configured to be released from the hole unless pulled out by applying a large force, the valve shaft rod 17 is the inner side of the hole The second valve 7 is allowed to move up and down longer than the vertical height of the diameter reducing part 16 which protrudes.

그리고 도면에 도시하는 것과 같이 직경축소부(16)에는 상하 방향으로 좁은 폭의 제2공기유통슬릿홈(21)이 1개 이상 형성되어 있으며, 이 제2공기유통슬릿홈(21)은 하측의 이탈방지머리(19)가 하부단턱면(20)에 밀착하더라도 가려지지 아니하고 상하로 항시 트여 있는 상태를 가지도록 형성된다.As shown in the drawing, at least one second air flow slit groove 21 having a narrow width in the vertical direction is formed in the diameter reduction portion 16, and the second air flow slit groove 21 has a lower side. Even if the departure preventing head 19 is in close contact with the lower stepped surface 20 is formed to have a state that is not covered and always up and down.

이와같은 본 발명은 용기본체(2)에 음식물을 담고 용기뚜껑(3)을 용기본체(2)에 장착하면, 패킹(5)이 내벽면(22)에 밀착하여 그 접촉면의 틈새를 밀봉하게 되며, 이 상태에서 진공밸브(4)의 제1밸브(6)를 눌러 그의 밸브원판(9)이 용기뚜껑(3) 표면에 밀착하도록 한 후 진공펌프(23)의 접속부(24)를 제2밸브장착공(14)의 상부구멍(14a)에 접속하고 진공펌프(23)를 가동하면 흡인력에 의해 제2밸브(7)가 상승하여 밸브머리(18)가 밸브시트인 단턱면(15)로부터 이격되면서 용기 내부의 공기가 제2공기유통슬릿홈(21), 상부구멍(14a), 접속부(24), 진공펌프(23)측으로 흡인 이동되어져 용기 내부의 공기가 없어져서 진공화된다.In the present invention, the container body (2) containing food and the container lid (3) is mounted on the container body (2), the packing (5) is in close contact with the inner wall surface 22 to seal the gap of the contact surface In this state, the first valve 6 of the vacuum valve 4 is pressed so that the valve disc 9 thereof is brought into close contact with the surface of the container lid 3, and then the connecting portion 24 of the vacuum pump 23 is moved to the second valve. When it is connected to the upper hole 14a of the mounting hole 14 and the vacuum pump 23 is operated, the 2nd valve 7 is raised by a suction force, and the valve head 18 is spaced apart from the step surface 15 which is a valve seat. As the air in the container is sucked and moved to the second air flow slit groove 21, the upper hole 14a, the connection part 24, and the vacuum pump 23, the air in the container is removed and is evacuated.

이때 접속부(24)를 분리시키면 용기 내부의 진공압에 의해 제2밸브(7)가 흡착되어져 밸브시트(15)에 밀착하여 공기유통 상태를 차단하게 되며, 이로써 용기 내부가 공기가 거의 존재하지 않는 상태가 되어 음식물의 장기간 보관이 가능하게 된다.At this time, if the connection part 24 is separated, the second valve 7 is adsorbed by the vacuum pressure inside the container, and the air valve adheres to the valve seat 15 to block the air flow state. Thus, there is almost no air in the container. It becomes a state, and long-term storage of food is possible.

다음에 용기 뚜껑(3)을 개방할 때에는 제1밸브(6)의 손잡이(13)를 잡고 상측으로 제1밸브(6)를 잡아빼듯이 들어올리게 되며, 제1밸브(6)가 상승하여 밸브원판(9)이 용기뚜껑(3) 표면에서 이격되게 되면 제1공기유통슬릿홈(12)의 상단에 용기뚜껑(3)의 제1밸브장착공(11)에 접하거나 또는 그 상부로 고개를 내밀게 되어 용 기 내외가 제1공기유통슬릿홈(12)을 통해 서로 연통하게 되며, 이로써 진공압인 용기 내부에 비해 상대적 고압인 대기가 개방된 제1공기유통슬릿홈(12)을 통해 용기 내부로 유입되어 진공이 파기되며, 용기뚜껑(3)의 흡인력이 제거되므로써 용기뚜껑(3)을 가볍게 용기본체(2)로부터 벗겨낼 수 있게 되는 것이다.Next, when the container lid 3 is opened, the handle 13 of the first valve 6 is grasped to lift the first valve 6 upward, and the first valve 6 is lifted up. When the disc 9 is spaced apart from the surface of the container lid 3, the upper surface of the first air flow slit groove 12 is in contact with the first valve mounting hole 11 of the container lid 3 or the head is raised upward. The inside and the outside of the container communicate with each other through the first air flow slit groove 12, and as a result, into the inside of the container through the first air flow slit groove 12 in which the atmosphere having a relatively high pressure is opened compared to the inside of the container under vacuum pressure. Inflow of the vacuum is destroyed, the suction force of the container lid (3) is removed so that the container lid (3) can be lightly peeled off from the container body (2).

이상과 같은 본 발명은 진공펌프를 접속하여 용기내의 공기를 외부로 인출하여 진공화시킬 수 있도록 제2밸브를 제1밸브 중심에 형성하여 진공밸브를 2중으로 구성하므로써, 별도로 구비하고 보관하여야 하는 진공펌프를 컴팩트하게 구성할 수 있고, 공기의 흡인 성능이 향상되고 진공펌프 접속부의 수명도 길어지게 되는 효과가 있다. According to the present invention as described above, the second valve is formed at the center of the first valve so that the air in the container can be taken out and vacuumized by connecting a vacuum pump, and the vacuum valve must be separately provided and stored. The pump can be compactly configured, and the air suction performance is improved, and the life of the vacuum pump connection portion is also long.
