The auxiliary lid of the crimping plate is an enlarged view of the assembled part.

상기 도면에서와 같이 본 발명의 밀폐용기(1)는 통상적인 밀폐용기와 같이 저장실(2a)을 갖는 본체(2); 상기 저장실(2a)을 개폐하는 뚜껑(3); 및 테두리에 설치된 제1패킹(4b)이 상기 저장실(2a) 내벽에 밀착되어 저장실(2a)에 저장된 음식물을 가압하고 내부에 관통된 구멍(4c)의 둘레에 플랜지(4d)가 돌출되며, 상기 구멍(4c)에는 보조뚜껑(4a)이 착탈가능하게 조립되어 그 테두리에 장착된 제2패킹(4a-1)이 플랜지(4d) 내벽에 밀착되어 저장실(2a)을 밀폐되게 가압하고, 상기 보조뚜껑(4a)에는 공기의 출입을 제어하는 마개(4a-2)가 장착된 압착판(4);을 포함한다.As shown in the drawing, the sealed container 1 of the present invention includes a main body 2 having a storage chamber 2a as in a conventional sealed container; A lid 3 for opening and closing the storage compartment 2a; And a first packing 4b installed at an edge thereof is in close contact with the inner wall of the storage compartment 2a to pressurize the food stored in the storage compartment 2a, and a flange 4d protrudes around the hole 4c penetrated therein. The auxiliary lid 4a is detachably assembled to the hole 4c, and the second packing 4a-1 attached to the edge thereof is in close contact with the inner wall of the flange 4d to pressurize the storage compartment 2a to be sealed. The lid 4a includes a pressing plate 4 equipped with a stopper 4a-2 for controlling the access of air.

이러한 밀폐용기에 있어서, 본 발명의 밀폐용기(1) 압착판(4)의 플랜지(4d)는 자유단부로 갈수록 지름이 작게 테이퍼면(4d-1)이 형성되고, 상기 테이퍼면(4d-1)의 내측 단부에는 상기 보조뚜껑(4a)의 제2패킹(4a-1)이 밀착되는 걸림턱(4d-2)이 돌출된다.In such a sealed container, the flange 4d of the pressurized plate 4 of the sealed container 1 of the present invention has a tapered surface 4d-1 having a smaller diameter toward the free end, and the tapered surface 4d-1. At the inner end portion of the), the locking step 4d-2 to which the second packing 4a-1 of the auxiliary lid 4a comes into close contact is protruded.

상기 플랜지(4d)의 테이퍼면(4d-1)은 자유단부로 갈수록 완만하게 경사지는데, 그 경사각은 저장실(2a) 내부 압력에 의해 보조뚜껑(4a)이 빠지지 않을 정도이어야 하고, 또한 압착판(4)을 저장실(2a)에서 빼내기 위해 사용자가 강제로 보조뚜껑(4a)을 잡아당길 때 플랜지(4d)에서 빠져나올 정도의 경사각을 가져야 함은 당연하다.The tapered surface 4d-1 of the flange 4d is gently inclined toward the free end, and the inclination angle of the flange 4d is such that the auxiliary lid 4a does not come out by the pressure inside the storage compartment 2a, and the pressing plate ( It is natural that the user should have an inclination angle enough to escape from the flange 4d when the user forcibly pulls the auxiliary lid 4a to remove the 4) from the storage compartment 2a.

이를 만족하기 위한 테이퍼의 비율은,The ratio of taper to satisfy this,

플랜지의 높이를 L, The height of the flange L,

플랜지의 확대부 구멍의 지름을 D,The diameter of the hole in the enlarged part of the flange is D,

플랜지의 축소부 구멍의 지름을 d,The diameter of the hole in the flange of the flange d,

라고 할 때 테이퍼 비율은 D-d/L가 되므로, 예컨대, 112-110/14이면, 테이퍼 비율은 1/7가 된다.In this case, the taper ratio is D-d / L, and therefore, for example, 112-110 / 14, the taper ratio is 1/7.

본 발명은 상기 테이퍼 비율은 1/7로 한정하지 않고 본 발명의 목적을 달성하기 위한 범위 내에서 결정될 수 있을 것이다.In the present invention, the taper ratio is not limited to 1/7 and may be determined within a range for achieving the object of the present invention.

상기 걸림턱(4d-2)은 플랜지의 축소부 구멍 단부에 돌출되게 형성되어, 상기 보조뚜껑(4a)이 빠지는 것을 방지하기 위한 것으로, 보조 안전장치의 기능을 하게 된다.The locking jaw (4d-2) is formed to protrude to the end of the hole of the reduction portion of the flange, to prevent the auxiliary lid (4a) to fall out, it will function as an auxiliary safety device.

이러한 걸림턱(4d-2)은 제2패킹(4a-1)이 걸림고정된 상태에서 사용시 빠지지 않도록 걸림턱(4d-2) 기능을 해야하고, 사용 후 압착판(4)을 저장실(2a)에서 제거하기 위해 마개(4a-2)를 잡아당겨 플랜지(4d)에서 보조뚜껑(4a)을 강제로 잡아당겨 먼저 분리시킬 때 제2패킹(4a-1)이 걸림턱(4d-2)을 통과할 수 있도록 완만하게 형성되어야 한다.The locking jaw 4d-2 should function as the locking jaw 4d-2 so that the second packing 4a-1 does not fall out when the second packing 4a-1 is locked, and the pressing plate 4 is stored in the storage compartment 2a after use. The second packing 4a-1 passes through the locking jaw 4d-2 when the stopper 4a-2 is pulled out to forcibly pull out the auxiliary lid 4a from the flange 4d to be removed. It should be formed gently so that it can be done.

이와 같이 구성되는 본 발명의 압착판(4)은 보조뚜껑(4a)이 끼워맞춤되는 플랜지(4d)의 상부가 좁고 하부가 넓은 형태로 테이퍼면(4d-1)이 형성되므로, 압착판(4)의 구멍(4c)에 보조뚜껑(4a)을 강제가 밀어넣으면 제2패킹(4a-1)이 구멍(4c) 내부로 억지끼움식으로 삽입된 다음 펼쳐지게 되므로, 이후 저장실(2a)의 압력을 받더라도 보조뚜껑(4a)은 제2패킹(4a-1)이 테이퍼 내면에 밀착되고 걸림턱(4d-2)에 걸리게 되면 구멍(4c)에서 빠지지 밀리지 않을 뿐만 아니라 빠지지 않게 된다.Since the pressing plate 4 of the present invention configured as described above has a tapered surface 4d-1 having a narrow upper portion and a lower lower portion of the flange 4d to which the auxiliary lid 4a is fitted, the pressing plate 4 When the auxiliary lid 4a is forcibly pushed into the hole 4c of the c), the second packing 4a-1 is inserted into the hole 4c by force insertion and then unfolded, so that the pressure of the storage compartment 2a is then increased. Even if the auxiliary lid (4a) is the second packing (4a-1) is in close contact with the inner surface of the taper and caught by the locking jaw (4d-2) not only does not fall out of the hole (4c) but also does not fall out.
