진공용기용 밸브장치{Valve device for vacuum containers} Valve device for vacuum containers

본 발명은 진공용기에 사용되는 밸브장치에 관한 것으로, 특히 밸브장치의 밸브 구조를 개선하여 밸브의 진공유지 능력을 향상시키면서 진공 해제를 용이하게 할 수 있는 밸브장치에 관한 것이다.The present invention relates to a valve device for use in a vacuum vessel, and more particularly to a valve device that can facilitate the vacuum release while improving the valve holding capacity of the valve device to improve the vacuum holding ability of the valve.

식품의 장기 보관을 위해 예전에는 주로 저온에서 보관하는 방법을 사용하였으나, 최근에는 진공용기를 사용하는 경우가 많아지고 있다. 이러한 용도의 진공용기에는 통상적으로 밸브장치가 구비되어서 진공펌프로 밸브장치를 통해 진공용기 내부의 공기를 배출시킨 후에 밸브장치를 폐쇄하여 용기 내 진공을 유지하고 필요한 경우에는 다시 밸브장치를 개방하여 용기 내 진공을 해제한다. For long-term storage of food was used in the past mainly the method of storing at low temperatures, but in recent years has been increasingly used vacuum containers. The vacuum container for this purpose is usually equipped with a valve device to discharge the air inside the vacuum container through the valve device with a vacuum pump, and then close the valve device to maintain the vacuum in the container and, if necessary, open the valve device again. I release my vacuum.

식품보관을 위한 진공용기에 사용되는 밸브장치의 일 예가 한국 공개특허 제2011-88085에 개시되어 있다. 밸브장치가 부착된 용기의 단면을 보여주는 도 1, 및 도 1의 밸브장치 부분을 확대한 것을 보여주는 도 2와 3을 참조하여 상기 공개된 밸브장치를 설명한다.An example of a valve device used in a vacuum container for food storage is disclosed in Korean Patent Laid-Open No. 2011-88085. The disclosed valve arrangement is described with reference to FIG. 1 showing a cross section of a vessel with a valve arrangement and FIGS. 2 and 3 showing an enlarged portion of the valve arrangement of FIG.

상기 밸브장치는 뚜껑(3)에 형성되는 밸브 결합부(4)와 밸브(10)로 구성된다. 밸브 결합부(4)는 뚜껑 상부에 형성되는 안착홈(5), 뚜껑 하부에 형성되며 공기 유동공을 갖는 돌기(7), 및 뚜껑을 관통하여 형성되는 통기공(6)을 포함한다. 가요성 재질로 제조되는 밸브(10)는 밀착면(20)을 가지며 밸브 결합부의 안착홈(5)과 결합하는 상부 디스크(11), 밸브 결합부의 돌기(7)와 결합하는 하부 디스크(12), 및 밸브 동체(14)를 따라 일측이 개방되도록 형성되는 중앙공(15)으로 구성된다. 상부 디스크(11)는 중앙에서 외측으로 갈수록 두께가 점점 얇아지며 밀착면(20)은 경사지게 형성된다.The valve device consists of a valve coupling portion 4 and a valve 10 formed on the lid 3. The valve coupling portion 4 includes a seating groove 5 formed in the upper portion of the lid, a protrusion 7 formed in the lower portion of the lid and having an air flow hole, and a vent hole 6 formed through the lid. The valve 10, which is made of a flexible material, has an adhesive surface 20 and has an upper disk 11 that engages with the seating groove 5 of the valve coupling portion, and a lower disk 12 that engages with the protrusion 7 of the valve coupling portion. , And a central hole 15 formed to open at one side along the valve body 14. The upper disk 11 is thinner and thinner from the center to the outside, and the contact surface 20 is formed to be inclined.

밸브(10)는 하부 디스크(12)가 통기공(6)을 통해 삽입되어 도 2에 도시된 바와 같이 위치된다. 이러한 삽입은 밸브에 형성된 중앙공(15)으로 인하여 용이하게 수행된다.The valve 10 is positioned as shown in FIG. 2 with the lower disk 12 inserted through the vent 6. This insertion is easily performed due to the central hole 15 formed in the valve.

진공용기 내부에 진공을 형성하려면, 도 2에 도시된 상태에서 진공펌프(미도시)의 흡입구를 상기 밸브장치에 밀착시켜 진공용기 내부의 공기를 외부로 강제배출시킨다. 펌프작동시 진공용기 내부 공기는 돌기(7)에 형성된 유동공과 통기공(6)을 통해 외부로 배출되며, 이러한 배출 시에 밸브의 상부 디스크(11)는 상부로 들어 올려지게 된다. 용기 내부에 진공이 형성되면, 도 3에 도시된 바와 같이, 상부 디스크(11)의 밀착면(20)이 안착홈(5)의 바닥과 밀착하여 통기공(6)을 폐쇄하게 된다. 용기 내부의 진공을 해제하려면, 밀착면(20)을 손가락 등으로 안착홈(5)의 바닥과 분리하거나 밸브 머리(17)를 좌,우로 밀어서 밀착면을 안착홈의 바닥과 분리하면 된다.In order to form a vacuum inside the vacuum container, the suction port of the vacuum pump (not shown) in close contact with the valve device in the state shown in Figure 2 forcibly discharges the air inside the vacuum container to the outside. During pump operation, the air inside the vacuum chamber is discharged to the outside through the flow hole and the vent hole 6 formed in the protrusion 7, and in this discharge, the upper disk 11 of the valve is lifted upward. When the vacuum is formed in the container, as shown in FIG. 3, the contact surface 20 of the upper disk 11 is in close contact with the bottom of the seating groove 5 to close the vent hole 6. To release the vacuum inside the container, the contact surface 20 may be separated from the bottom of the seating groove 5 with a finger or the like, or the valve head 17 may be pushed left and right to separate the contact surface from the bottom of the seating groove.

전술한 밸브장치는 구성이 간단하며 용이하게 진공용기 내부에 진공을 형성할 수 있다는 장점이 있으나, 장시간 진공이 유지되지 않으며, 진공 해제하는 것이 불편하다는 문제점이 있다.The above-described valve device has the advantage that the configuration is simple and can easily form a vacuum inside the vacuum vessel, but the vacuum is not maintained for a long time, there is a problem that it is inconvenient to release the vacuum.

본 발명의 목적은 공지 밸브장치의 구조를 개선하여 진공용기 내부의 진공이 장시간 유지될 수 있으며 내부의 진공 해제가 용이하도록 하는 밸브장치를 제공하는 것이다.An object of the present invention is to improve the structure of the known valve device to provide a valve device that can be maintained for a long time the vacuum inside the vacuum vessel and to facilitate the release of the vacuum inside.

상기 목적을 위해, 본 발명은 본체(2)와 이 본체에 탈,부착되는 뚜껑(3)으로 이루어진 진공용기에 사용되며 뚜껑(3)에 형성되는 밸브 결합부(4)와 밸브(10)로 구성되는 공지의 밸브장치에 있어서, 밸브의 밀착면에 원주방향으로 둥근 홈이 형성된 밸브장치를 제공한다. 이 홈은 진공용기 내부의 진공과는 별개의 독립된 진공을 제공함으로써 밸브 밀착면이 밸브 안착홈의 바닥과 더욱 밀착하게 하여 진공용기 내부에 형성된 진공을 장시간 유지하게 한다. 이 홈은 홈의 중심이 밸브의 중앙 축을 향해 편심되어 있는 것이 바람직하다. 이러한 편심에 의해 밸브 머리를 좌,우로 밀면 밸브 밀착면이 밸브 안착홈과 용이하게 분리된다.For this purpose, the present invention is used in the vacuum container consisting of the main body 2 and the lid 3 attached to and detached from the main body, and the valve coupling portion 4 and the valve 10 formed on the lid 3; A well-known valve device configured to provide a valve device in which a round groove is formed in a circumferential direction on a contact surface of a valve. This groove provides a vacuum independent of the vacuum inside the vacuum vessel, thereby making the valve contact surface more closely contact the bottom of the valve seating groove to maintain the vacuum formed inside the vacuum vessel for a long time. It is preferable that the center of the groove is eccentric toward the central axis of the valve. When the valve head is pushed left and right by such eccentricity, the valve contact surface is easily separated from the valve seating groove.

또한, 상기 밸브의 중앙동체에 밸브 결합부의 통기공과 밀착하는 돌기가 형성된다. 이 돌기는 통기공을 더욱 강력하게 폐쇄하는 역할을 하여 진공용기 내부에 형성된 진공을 장시간 유지하는데 도움이 된다.In addition, a protrusion is formed on the central body of the valve in close contact with the vent hole of the valve coupling portion. This protrusion serves to close the vent more strongly, which helps to maintain the vacuum formed inside the vacuum chamber for a long time.

또한, 상기 밸브 결합부의 안착홈 바닥과 통기공이 만나는 부분이 곡면으로 형성되며, 상기 밸브의 상부 디스크와 중앙동체가 만나는 부분 역시 상기 곡면에 상응하도록 곡면으로 형성된다. 이러한 구조는 밸브와 밸브 결합부가 더욱 밀착하게 하여 진공용기 내부에 형성된 진공을 장시간 유지하는데 도움이 된다.In addition, a portion where the bottom of the seating groove of the valve coupling portion and the vent hole meet is formed as a curved surface, and a portion where the upper disk and the central body of the valve meet is also formed as a curved surface corresponding to the curved surface. This structure makes the valve and the valve coupling portion more tightly, which helps to maintain the vacuum formed inside the vacuum container for a long time.

본 발명에 의하면, 구성이 비교적 간단한 밸브장치에 의해 진공용기 내부에 용이하게 진공이 형성되고 이 진공이 장시간 유지될 수 있다. 또한 본 발명에 의하면, 밸브 머리를 좌,우로 밀어서 밸브 밀착면이 밸브 안착홈과 용이하게 분리됨으로써 진공이 용이하게 해제된다.According to the present invention, a vacuum is easily formed inside the vacuum container by a valve device having a relatively simple configuration, and the vacuum can be maintained for a long time. In addition, according to the present invention, the valve head is easily released by pushing the valve head to the left and right to separate the valve seating groove from the valve seating groove.

이하에 첨부도면 4 내지 8을 참조하여 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings 4 to 8.

본 발명은 전술한 공지의 공기밸브장치의 구조를 개선한 것이다. 따라서, 도 4 내지 8을 참조하여 본 발명에 따른 공기밸브장치를 설명할 때, 도 1 내지 3에 도시된 공지의 공기밸브장치에서 이미 설명된 부분은 생략하고 개선된 구조부분만을 설명하며, 도 1 내지 6에서 동일한 참조번호는 동일한 기능을 하는 밸브요소를 나타낸다.The present invention improves the structure of the above-mentioned known air valve device. Therefore, when describing the air valve device according to the present invention with reference to FIGS. 4 to 8, the parts already described in the known air valve device shown in FIGS. The same reference numerals in 1 to 6 denote valve elements having the same function.

종래의 공기 밸브장치의 밸브 결합부(4)의 구조를 개선하였는바, 본 발명에 따른 공기밸브장치의 밸브 결합부(4')의 경우, 안착홈(5)의 바닥과 통기공(6)의 내벽(9)이 만나는 부분을, 도 7과 8에 도시된 바와 같이, 곡면으로 형성하였다. The structure of the valve coupling part 4 of the conventional air valve device is improved. In the case of the valve coupling part 4 'of the air valve device according to the present invention, the bottom of the seating groove 5 and the vent hole 6 are provided. The portion where the inner wall 9 meets was formed into a curved surface, as shown in FIGS. 7 and 8.

본 발명에 따른 공기밸브장치에 사용되는 밸브(10')는 가장 중요한 구조적 변경이 행해진 부분이다.The valve 10 'used in the air valve device according to the present invention is the part where the most important structural changes have been made.

우선, 밸브(10')의 밀착면(20)에 원주방향으로 둥근 홈(21')이 형성된다(도 6 참조). 이러한 홈(21')이 형성되면, 진공펌프로 용기 내부에 진공을 형성할 때, 이 홈(21')과 밸브 결합부(4')의 안착홈(5) 바닥 사이에 용기 내부에 형성되는 진공과는 별도로 독립된 진공부가 형성되며, 이 진공부는 밀착면(20)의 안착홈(5) 바닥에 대한 밀착을 강화시켜주는 역할을 한다. 이는 종래의 경우에 비해 진공용기 내부에 형성된 진공을 더욱 장시간 유지할 수 있게 해준다.First, a circumferentially rounded groove 21 'is formed in the contact surface 20 of the valve 10' (see Fig. 6). When such a groove 21 'is formed, when a vacuum is formed inside the container with a vacuum pump, the groove 21' is formed inside the container between the groove 21 'and the bottom of the seating groove 5 of the valve coupling part 4'. A vacuum unit is formed separately from the vacuum, and the vacuum unit serves to strengthen the adhesion to the bottom of the mounting groove 5 of the contact surface 20. This allows the vacuum formed inside the vacuum vessel to be maintained for a longer time than in the conventional case.

한편, 도 4와 5에 도시된 바와 같이, 홈의 중심이 밸브(10')의 중앙 축을 향해 편심되게 홈(21)이 형성되는 것이 바람직하다. 홈(21)이 이와 같이 편심되게 형성되면, 도 8과 같이 밸브(10')가 안착홈(5) 바닥과 밀착되어 용기 내부에 진공이 형성된 후 다시 이 진공을 해제하고자 밸브 머리(17)를 좌,우로 밀 때, 홈(21)의 편심 방향의 벽(22) 부분이 일종의 중간 지지부 역할을 하여서 밀착면(20) 말단부(29)가 안착홈(5) 바닥과 분리하는 것을 용이하게 한다. 따라서 편심 홈(21)은 평상시에는 홈(21)과 밸브 결합부(4')의 안착홈(5) 바닥 사이에 별도의 진공부를 형성하여 밀착면(20)의 안착홈(5)에 대한 밀착을 강화시키는 역할을 하고, 진공을 해제하고자 밸브 머리(17)를 좌,우로 밀 때 밀착면(20) 말단부(29)가 안착홈(5) 바닥과 용이하게 분리되도록 하여 용기 내의 진공 해제를 손쉽게 달성하게 한다.On the other hand, as shown in Figures 4 and 5, it is preferable that the groove 21 is formed so that the center of the groove is eccentric toward the central axis of the valve 10 '. When the groove 21 is eccentrically formed as described above, as shown in FIG. 8, the valve 10 ′ is in close contact with the bottom of the seating groove 5 to form a vacuum in the container, and then the valve head 17 is again released to release the vacuum. When pushed left and right, the eccentric wall 22 portion of the groove 21 acts as a kind of intermediate support to facilitate separation of the contact surface 20 end 29 from the bottom of the seating groove 5. Therefore, the eccentric groove 21 usually forms a separate vacuum portion between the groove 21 and the bottom of the seating groove 5 of the valve coupling part 4 ′ for the seating groove 5 of the contact surface 20. When the valve head 17 is pushed to the left or right to release the vacuum, the contact surface 20 and the distal end 29 are easily separated from the bottom of the seating groove 5 to release the vacuum. Make it easy to achieve.

다음으로, 본원 발명의 밸브(10')는 밸브의 중앙동체(14) 외벽에 돌기(27)가 형성된다. 이 돌기(27)는 밸브 결합부(4')의 통기공(6)과 밀착하여서 통기공(6)을 더욱 강력하게 폐쇄하는 역할을 하여 진공용기 내부에 형성된 진공을 장시간 유지하는데 도움을 준다. 이때, 과도한 밀착은 진공펌프로 용기 내부에 진공을 형성할 때 펌프질에 장애를 줄 수 있으므로, 돌기(27)의 크기는 진공펌프의 펌프질에 과도한 부담을 주지 않으면서 진공 용기 내부에 형성된 진공 유지를 위해 통기공(6)을 일차적으로 폐쇄할 수 있을 정도로만 형성되는 것이 바람직하다. Next, the valve 10 'of the present invention is provided with a projection 27 on the outer wall of the central body 14 of the valve. This projection 27 is in close contact with the vent hole 6 of the valve coupling portion 4 'serves to close the vent hole 6 more strongly to help maintain the vacuum formed inside the vacuum vessel for a long time. At this time, excessive adhesion may impede the quality of the pump when the vacuum is formed inside the container by the vacuum pump, the size of the projection 27 is to maintain the vacuum formed inside the vacuum container without excessive burden on the pump quality of the vacuum pump It is preferable to form only enough to be able to close the vent hole 6 primarily.

또한, 전술한 바와 같이, 상기 밸브 결합부(4')의 안착홈(5) 바닥과 통기공(6)의 내벽(9)이 만나는 부분을 곡면으로 형성한 것에 대응하여, 이 부분에 상응하는 밸브(10')의 부분, 즉 밸브(10')의 상부 디스크(11)와 중앙동체(14)가 만나는 부분 역시 상기 곡면에 상응하도록 곡면으로 형성된다. 이러한 구조는 용기 내부에 진공이 형성되는 경우, 밸브(10')와 밸브 결합부(4')가 더욱 밀착하게 하여 진공용기 내부에 형성된 진공을 장시간 유지하는데 도움이 된다. In addition, as described above, a portion where the bottom of the seating groove 5 of the valve engaging portion 4 'and the inner wall 9 of the vent hole 6 meet is formed into a curved surface, corresponding to this portion. A portion of the valve 10 ', that is, a portion where the upper disk 11 and the central body 14 of the valve 10' meet, is also formed to be curved to correspond to the curved surface. This structure helps to maintain the vacuum formed inside the vacuum container for a long time by making the valve 10 'and the valve coupling portion 4' become more in close contact when a vacuum is formed inside the container.

이상에서는 첨부도면을 기초로 본원 발명을 설명하였으나, 당업자라면 본원 발명의 범위 내에서 다양한 변경이 가능함을 알 수 있을 것이다. 예를 들면, 상기 구조적 변경 부분은 각기 독립적으로 또는 상호 조합하여 적용될 수 있을 것이다.In the above described the present invention based on the accompanying drawings, those skilled in the art will recognize that various changes are possible within the scope of the present invention. For example, the structural modifications may be applied independently or in combination with each other.
