Description

진공밀폐용기{Vacuum airtight container}[0001] Vacuum airtight container [0002]

본 발명은 진공밀폐용기에 관한 것으로, 보다 상세하게는 각종 음식물을 진공상태로 보관할 수 있는 진공밀폐용기에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vacuum sealed container, and more particularly, to a vacuum sealed container capable of storing various foods in a vacuum state.

일반적으로 각종 야채, 육류, 어류 등과 같은 음식물은 공기 중의 미생물, 산소, 기타 유해 물질들과의 접촉으로 인해 쉽게 산화되면서 부패된다. 또한 발효식품의 경우에는 미생물의 번식이 더욱 활성화되면서 음식물의 발효가 지나치게 빨리 진행되어 보존성이 좋지 못한 문제가 있다. 이에 따라, 음식물의 변질 및 부패를 방지하거나 발효를 지연시키기 위해서는 음식물이 외부공기와 접촉하지 못하도록 차단해야만 한다. 이러한 목적을 위해서 상면이 개방되며 음식물이 저장되는 용기본체의 상면에 착탈되는 뚜껑으로 이루어진 밀폐용기가 제안되었다. 종래의 밀폐용기는 주지된 바와 같이 용기본체와 접촉되는 뚜껑의 테두리에 링 형상의 패킹을 결합하여 용기본체를 밀폐시켰다.Generally, foods such as various vegetables, meat, fish, etc. are easily oxidized and decayed due to contact with microorganisms, oxygen and other harmful substances in the air. In addition, in the case of fermented food, the propagation of the microorganism is further activated, and the fermentation of the food proceeds too quickly, resulting in poor preservability. Accordingly, in order to prevent deterioration and decay of food or to delay fermentation, food must be prevented from coming into contact with outside air. For this purpose, there has been proposed an airtight container made of a lid which is opened and closed on the upper surface of a container body in which foods are stored. Conventionally, the sealed container is sealed with a ring-shaped packing by joining the rim of the lid which is in contact with the container body as is well known.

그런데 이와 같이 종래의 밀폐용기는 용기본체를 밀폐시켜 외부공기가 용기의 내부로 유입되는 것은 차단하더라도, 용기본체의 내부에 잔류된 공기에 의해 용기본체에 저장된 음식물이 부패되거나 발효속도가 빨라지게 되는 문제는 여전히 해결되지 못하고 있다. 이에 따라, 뚜껑에 밸브를 장착하고 별도의 진공펌프를 이용하여 용기본체의 내부를 진공상태로 만들기도 하지만, 용기본체 및 뚜껑과 별체로 이루어진 진공펌프를 용기본체 및 뚜껑과는 별개로 보관해야 하므로 분실우려가 있고 분실시 용기본체의 내부를 진공상태로 만들수가 없고 진공펌프를 각 용기의 뚜껑마다 밸브와 위치정렬되게 장착하여 사용하고 사용후에는 분리보관해야 하므로 사용이 번거로운 문제가 있다.However, even if the conventional closed container hermetically closes the container body to block the introduction of the outside air into the container, the food stored in the container body is spoiled by the air remaining inside the container body or the fermentation speed is increased The problem is still not resolved. Accordingly, although a valve is attached to the lid and a separate vacuum pump is used to make the inside of the container body a vacuum state, the vacuum pump made of the container body and the lid and the separate body must be kept separate from the container body and the lid It is impossible to make the inside of the container body vacuum when it is lost and there is a problem that it is troublesome to use the vacuum pump because the vacuum pump is installed in the lid of each container so as to be aligned with the valve,

The pair of pivoting cylinders 31 has a horizontal portion 31a whose one end is rotatably coupled to each hinge portion 22 of the container cover 20 and a pair of pivotally extending upwardly bent portions 31a And a knee-like shape including a vertical portion 31b to which the knob 30 is vertically coupled. As shown in FIG. 2, the at least one pivoting cylinder 31 is formed with a knurling-like bending passage 34, 35 passing through the horizontal portion 31a and the vertical portion 31b, The inlet end 32 forms an inlet 32 into which the air in the container body 10 flows into the bending flow paths 34 and 35. [ It is a matter of course that the pivoting cylinder 31 in which the bending flow paths 34 and 35 are not formed has a hollow in which the handle 30 can be raised and lowered. 2, a cap 33a having an outlet 33 is coupled to the upper end of the vertical portion 31b of the rotary cylinder 31. As shown in FIG. A packing 39 is provided between the horizontal portion 31a of the pivoting cylinder 31 and the hinge portion 22 of the container cover 20.

상기 손잡이(30)는 사용자가 파지할 수 있는 파지부(37)와, 이 파지부(37)의 양단부에서 일체로 돌출되어 한 쌍의 회동실린더(31)에 승강가능하게 결합된 한 쌍의 수직연장부(36)를 포함한다. 이와 같은 손잡이(30)는 디귿자 형상을 이룬다.The handle 30 includes a grip portion 37 that can be gripped by a user and a pair of vertically coupled vertically protruding portions that protrude integrally from both ends of the grip portion 37 and are pivotally connected to a pair of pivoting cylinders 31 And includes an extension portion 36. Such a handle 30 has a diaphragm shape.

한편, 도 2와 같이 한 쌍의 수직연장부(36)는 일단이 각 회동실린더(31)의 내부로 승강가능하게 결합되고, 적어도 하나의 수직연장부(36)의 하단부에는 직경이 확장된 제1 및 제2확장판(36a,36b)이 상하로 일정간격(d) 이격 배치된다. 그리고 적어도 하나의 회동실린더(31) 또는 손잡이(30)의 수직연장부(36)에는 회동실린더(31)의 절곡유로(34,35)를 외부와 연통시키는 통기로(38)가 형성된다. 이 통기로(38)는 수직연장부(36)와 회동실린더(31) 사이 틈새가 되거나 또는 회동실린더(31)에 형성될 수도 있지만, 도 2와 같이 수직연장부(36)의 둘레면에 오목하며 상하로 연장된 형태를 예시하였다. 이때, 도 3과 같이 통기로(38)의 상단은 제1확장판(36a)의 상면을 관통하고 하단은 제2확장판(36b)의 상단보다 상측에 위치된다. As shown in FIG. 2, the pair of vertical extending portions 36 are coupled to one end of the rotary cylinder 31 so as to be able to move up and down, and at the lower end of the at least one vertical extending portion 36, 1 and the second extension plates 36a and 36b are vertically spaced apart from each other by a predetermined distance d. The at least one pivoting cylinder 31 or the vertically extending portion 36 of the handle 30 is provided with an air passage 38 for communicating the bending passage 34, 35 of the pivoting cylinder 31 with the outside. This vent path 38 may be a gap between the vertical extending portion 36 and the pivoting cylinder 31 or may be formed in the pivoting cylinder 31. However, And extended to the top and bottom. 3, the upper end of the ventilation passage 38 passes through the upper surface of the first expansion plate 36a, and the lower end thereof is positioned above the upper end of the second expansion plate 36b.

상기 제1체크밸브(40)는 손잡이(30)의 승강에 따라 용기본체(10)의 내부에 잔류된 공기가 회동실린더(31)의 절곡유로(34,35)상으로 배출되되 절곡유로(34,35)상의 공기가 용기본체(10)의 내부로 유입되는 것을 차단하도록 회동실린더(31)의 유입구(32)를 개폐한다. 제1체크밸브(50)는 용기커버(20)의 힌지부(22)의 통공(23) 또는 회동실린더(31)의 유입구(32)에 설치된다. The first check valve 40 allows the air remaining inside the container body 10 to be discharged onto the bending flow channels 34 and 35 of the rotating cylinder 31 as the handle 30 is lifted and lowered, Closing the inlet port 32 of the rotating cylinder 31 to block the air on the container body 10 from flowing into the container body 10. The first check valve 50 is installed in the through hole 23 of the hinge portion 22 of the container cover 20 or the inlet 32 of the pivoting cylinder 31.

상기 제2체크밸브(50)는 손잡이(30)의 승강에 따라 상기 통기로(38)을 개폐하는 것으로, 링 형상으로 이루어져서 손잡이(30)의 수직연장부(36)에 끼워지되 제1 및 제2확장판(36a,36b) 사이에 위치된다. 제2체크밸브(50)는 고무재 등으로 이루어져서 외측면이 회동실린더(31)의 내측면에 밀착되어, 회동실린더(31)의 절곡유로(34,35)를 상측유로(34) 및 하측유로(35)로 구획한다. 한편, 도 2와 같이 제2체크밸브(50)의 두께(t)는 손잡이(30)의 수직연장부(36)의 제1 및 제2확장판(36a,36b) 사이의 간격(d)보다 작게 형성되되 도 3과 같이 제1확장판(36a)의 하단에서 통기로(38)의 하단까지의 길이(d1)보다 작게 형성된다. 이에 따라, 도 2와 같이 제2체크밸브(50)는 손잡이(30)의 수직연장부(36)가 상승하면 제2확장판(36b)에 밀착되어 상측 및 하측유로(34,35)가 격리되도록 통기로(38)를 폐쇄시킨다. 도 3과 같이, 제2체크밸브(50)는 손잡이(30)의 수직연장부(36)가 하강하면 제1확장판(36a)에 밀착되어 상측 및 하측유로(34,35)가 연통되도록 통기로(38)를 개방시킨다.The second check valve 50 opens and closes the ventilation passage 38 as the handle 30 is lifted and lowered and is formed in a ring shape and fitted in the vertical extension 36 of the handle 30, 2 extension plates 36a, 36b. The second check valve 50 is made of rubber or the like so that its outer surface is in close contact with the inner surface of the rotating cylinder 31 so that the bending flow paths 34 and 35 of the rotating cylinder 31 are connected to the upper flow path 34 and the lower flow path 34, (35). 2, the thickness t of the second check valve 50 is smaller than the distance d between the first and second extension plates 36a and 36b of the vertical extension 36 of the handle 30 And is formed to be smaller than the length d1 from the lower end of the first expansion plate 36a to the lower end of the air passage 38 as shown in FIG. 2, when the vertical extension 36 of the handle 30 is raised, the second check valve 50 is brought into close contact with the second expansion plate 36b so that the upper and lower flow passages 34 and 35 are isolated from each other Thereby closing the air passage 38. 3, when the vertically extending portion 36 of the handle 30 descends, the second check valve 50 is brought into close contact with the first expansion plate 36a so that the upper and lower flow paths 34, (38) is opened.

상기 흡기밸브(60)는 용기커버(20)의 흡기공(24)에 설치되어 용기커버(20)에 의해 밀폐된 용기본체(10)의 내부의 진공상태를 해제하여 용기커버(20)를 용기본체(10)에서 보다 용이하게 분리시키도록 해준다. 이 흡기밸브(60)는 사용자가 잡아당기거나 측방으로 밀면 흡기공(24)을 개방시키는 형태가 바람직하다. The intake valve 60 is installed on the intake hole 24 of the container cover 20 to release the vacuum state inside the container body 10 which is sealed by the container cover 20, So that it can be easily separated from the main body 10. It is preferable that the intake valve 60 opens the intake hole 24 when the user pulls it or sideways.

이와 같이 구성된 본 발명의 제1실시예에 따른 진공밀폐용기에서 용기본체(10)의 내부를 진공시켜 음식물의 부패 및 발효속도를 늦추는 방법에 대해 설명한다. In the vacuum hermetic container according to the first embodiment of the present invention constructed as described above, a method of reducing the decay and the fermentation speed of the food by vacuuming the inside of the container body 10 will be described.

도 1과 같이 용기커버(20)를 음식물이 저장된 용기본체(10)에 장착하고, 도 2와 같이 손잡이(30)를 들어올리면 수직연장부(36)가 상승함에 따라 회동실린더(31)의 절곡유로(34,35) 중 하측유로(35)가 팽창된다. 이에 따라, 하측유로(35)의 압력이 용기본체(10)의 내부압력보다 상대적으로 작아지므로, 제1체크밸브(40)는 용기커버(20)의 힌지부(22)의 통공(23)을 개방시킨다. 또한 제2체크밸브(50)는 손잡이(30)의 수직연장부(36)가 상승함 따라 제2확장판(36b)에 밀착되어 통기로(38)를 폐쇄시킨다. 따라서 용기본체(10)의 내부에 잔류된 공기가 회동실린더(31)의 하측유로(35)상으로 진공흡입된다. As shown in FIG. 1, when the container cover 20 is mounted on the container body 10 in which the food is stored and the handle 30 is lifted as shown in FIG. 2, the vertical extension 36 rises, The lower flow path 35 of the flow paths 34 and 35 expands. As a result, the pressure of the lower flow path 35 becomes relatively smaller than the inner pressure of the container body 10, so that the first check valve 40 can be opened and closed in the through hole 23 of the hinge portion 22 of the container cover 20 Open. The second check valve 50 is brought into close contact with the second expansion plate 36b as the vertical extension 36 of the handle 30 rises and closes the ventilation passage 38. Therefore, the air remaining inside the container body 10 is sucked into the lower flow path 35 of the rotating cylinder 31 by vacuum.

그리고 도 3과 같이 손잡이(30)를 하강시키면 수직연장부(36)가 하강함에 따라 회동실린더(31)의 절곡유로(34,35) 중 하측유로(35)가 압축된다. 이에 따라, 하측유로(35)의 압력이 용기본체(10)의 내부압력보다 상대적으로 커지므로, 제1체크밸브(40)는 용기커버(20)의 힌지부(22)의 통공(23)을 폐쇄시킨다. 또한 제2체크밸브(50)는 손잡이(30)의 수직연장부(36)가 하강함에 따라 제1확장판(36a)에 밀착되어 통기로(38)를 개방시킨다. 따라서 회동실린더(31)의 하측유로(35)상에 압축된 공기는 개방된 통기로(38)를 통해 외부로 배출되고 용기본체(10)의 내부로는 유입되지 않는다. 3, when the handle 30 is lowered, the lower flow path 35 of the bending flow paths 34 and 35 of the rotating cylinder 31 is compressed as the vertical extending portion 36 is lowered. As a result, the pressure of the lower flow path 35 becomes relatively larger than the internal pressure of the container main body 10, so that the first check valve 40 can be opened and closed in the through hole 23 of the hinge portion 22 of the container cover 20 Closing. The second check valve 50 is brought into close contact with the first expansion plate 36a to open the ventilation passage 38 as the vertical extension 36 of the handle 30 descends. The compressed air on the lower flow path 35 of the rotating cylinder 31 is discharged to the outside through the opened air passage 38 and does not flow into the interior of the container body 10. [

이와 같은 과정을 반복함에 따라 용기본체(10)의 내부의 잔류된 공기가 외부로 모두 배출되어 용기본체(10)의 내부는 진공상태가 된다. 이에 따라, 용기본체(10)에 저장된 음식물의 부패 및 발효속도가 지연되어 좀 더 오래시간 신선함을 유지할 수 있게 된다. By repeating this process, the remaining air inside the container body 10 is discharged to the outside, and the inside of the container body 10 becomes a vacuum state. Accordingly, the decay and the fermentation speed of the food stored in the container body 10 are delayed, so that it is possible to maintain freshness for a longer time.

도 4 내지 도 7은 본 발명의 제2실시예에 따른 진공밀폐용기를 도시한 것으로, 손잡이(30)의 수직연장부(36)의 하단에 직경이 확장된 단일의 확장판(36c)이 구비된다. 이 확장판(36c)의 외주면에는 회동실린더(31)의 내주면에 밀착되는 패킹(39a)이 구비되어, 확장판(36c)에 의해 회동실린더(31)의 절곡유로(34,35)가 상측유로(34) 및 하측유로(35)로 구획된다. 그리고 배출구(33)가 형성된 너트체(33b)가 회동실린더(31)의 수직부(31b)의 상단에 나사결합된다. 한편, 통기로(38)는 수직연장부(36)의 확장판(36c)에 상하로 관통되며 복수개가 원주방향을 따라 이격 형성된다. 4 to 7 illustrate a vacuum sealed container according to a second embodiment of the present invention and a single expansion plate 36c having a diameter expanded at the lower end of the vertical extension 36 of the handle 30 is provided . The expansion plate 36c is provided with a packing 39a which is in close contact with the inner circumferential surface of the rotary cylinder 31 so that the bending flow channels 34 and 35 of the rotary cylinder 31 are connected to the upper flow channel 34 And the lower flow path 35, respectively. The nut member 33b formed with the discharge port 33 is screwed to the upper end of the vertical portion 31b of the rotary cylinder 31. [ On the other hand, the ventilation passage 38 is vertically passed through the extension plate 36c of the vertical extension portion 36, and a plurality of ventilation passages 38 are formed along the circumferential direction.

한편, 제1체크밸브(40)는 회동실린더(31)의 유입구(32)에 직접 결합되고, 제2체크밸브(50)는 판상으로 이루어져서 손잡이(30)의 확장판(36c)에 결합되되 일정부위가 절개되어 회동실린더(31)의 하측유로(35)의 압력의 증감에 따라 상하로 회동되어 통기로(38)를 개폐한다. The first check valve 40 is directly coupled to the inlet 32 of the pivoting cylinder 31 and the second check valve 50 is formed in a plate shape and coupled to the extension plate 36c of the handle 30, And is turned up and down in accordance with the increase or decrease in the pressure of the lower flow path 35 of the rotary cylinder 31 to open and close the air passage 38. [

그리고 회동실린더(31)의 수직부(31b)에는 손잡이(30)의 수직연장부(36)의 확장판(36c)이 걸려지는 걸림턱(31c)이 형성되어 손잡이(30)의 수직연장부(36)의 하강이 제한되므로, 사용자가 손잡이(30)를 승강시킬 때 과도한 힘을 주게 되더라도 수직연장부(36)와 파지부(37)가 회동실린더(31)와 충돌되어 파손되는 것이 방지된다. The vertical portion 31b of the pivoting cylinder 31 is formed with a latching protrusion 31c for latching the extension plate 36c of the vertical extension 36 of the handle 30, The vertical extension portion 36 and the grip portion 37 are prevented from colliding with the rotating cylinder 31 and being damaged even if the user gives excessive force when raising and lowering the handle 30.
