Description

밀폐용기의 밀폐장치{Sealed Packing Apparatus for Sealed Container}Sealing device for sealed container {Sealed Packing Apparatus for Sealed Container}

본 발명은 밀폐용기에 특이한 구조를 적용하여 유체(액체 또는 기체)의 누설을 방지하는 밀폐용기의 밀폐장치에 관한 것이다.The present invention relates to a sealing device for a sealed container by applying a specific structure to the sealed container to prevent the leakage of fluid (liquid or gas).

일반적인 밀폐용기는 도1에 도시한 바와 같이, 상부가 개방된 용기몸체(1)와, 이 용기몸체(1)를 개폐하는 용기커버(2)과, 이 용기커버(2)를 용기몸체(1)의 개방부에 닫아 잠그기 위한 잠금플랜지(3)를 갖추고 있다. As shown in FIG. 1, a general sealed container includes a container body 1 having an open top, a container cover 2 for opening and closing the container body 1, and a container cover 2 with the container body 1 It is equipped with a locking flange (3) for closing and closing the opening of the).

상기 용기몸체(1)는 통상 사각의 통으로 이루어져 내부에 저장공간을 형성한다. 또한, 용기몸체(1)의 네 측벽(1a)(1b)의 개방 단부에는 잠금돌기(4)가 마련되는데, 이 잠금돌기(4)들은 용기몸체(1) 측벽(1a)(1b)의 외면을 따라 다수개가 돌출되게 형성되어 있다. 상기 용기커버(2)의 저면에는 가장자리를 따라 패킹이 삽입되는 시일링홈(미도시)이 형성되어 있어서, 용기몸체(1)의 개방단부가 시일링홈에 삽입되어 패킹을 누르게 된다. 그리고 상기 잠금플랜지(3)는 용기커버(2)의 네변에 각각 바깥측으로 선회(도면에서 화살표 방향) 가능하게 일체로 이루어지며, 각각에는 상기 잠금돌기(4)에 대응하는 잠금홀(5)이 형성되어 있다.The container body 1 is usually made of a rectangular tube to form a storage space therein. In addition, the locking projections 4 are provided at the open ends of the four sidewalls 1a and 1b of the container body 1, and the locking protrusions 4 are the outer surfaces of the side walls 1a and 1b of the container body 1. Along the plurality is formed to protrude. The bottom surface of the container cover (2) is formed with a sealing groove (not shown) through which the packing is inserted along the edge, the open end of the container body (1) is inserted into the sealing groove to press the packing. The locking flange 3 is integrally formed on four sides of the container cover 2 so as to be able to pivot outwardly (in the direction of the arrow in the drawing), and each of the locking holes 5 corresponding to the locking protrusion 4 is provided. Formed.

이에 따라 내용물 보관할 때에는 용기몸체(1)의 저장공간에 내용물을 넣고 용기커버(2)를 덮게 되며, 이러한 상태에서 용기커버(2)에 마련된 잠금플랜지(3)들을 각각 하측을 내려 누르면, 용기몸체(1)의 측벽(1a)(1b)에 마련된 잠금돌기(4)가 잠금홀(5)에 탄성 결합되어 용기커버(2)가 견실하게 잠겨진다. 그리고, 잠금플랜지(3)를 바깥측을 향하여 상측으로 들어 올리면, 잠금돌기(4)들의 구속이 해제되며 이로 인해 용기커버(2)를 열 수 있다.Accordingly, when the contents are stored, the contents are placed in the storage space of the container body 1 and the container cover 2 is covered. In this state, the locking flanges 3 provided on the container cover 2 are lowered, respectively, to lower the container body. The locking projection 4 provided on the side walls 1a and 1b of (1) is elastically coupled to the locking hole 5 so that the container cover 2 is securely locked. Then, when the locking flange 3 is lifted upward toward the outside, restraint of the locking protrusions 4 is released, thereby opening the container cover 2.

그런데, 밀폐용기의 크기가 크게 되면, 패킹과 용기몸체의 접촉면적이 커짐에 따른 반발력의 증가로 인해 용기를 밀폐할 때에 접촉면의 압입성능이 저하되어 용기커버 자체의 변형, 운반시 유동 등에 의해 유체(액체 또는 기체)의 누설현상이 발생된다는 문제점이 있었다.However, when the size of the sealed container is increased, the indentation performance of the contact surface decreases when the container is closed due to an increase in repulsion force due to an increase in the contact area between the packing and the container body. There was a problem that leakage phenomenon (liquid or gas) occurs.

또한, 대형 밀폐용기의 경우에는 용기커버의 잠금플랜지 사이의 간격이 크게 되므로, 용기 자체의 밴딩과 잠금플랜지로 잠글 때에 지렛대의 원리에 의해 용기커버가 중심방향으로 솟아오르려는 경향이 발생되어, 용기커버의 잠금플랜지 사이의 간격 부분에 국부적인 들뜸현상이 발생하여 밀폐성이 저하된다는 문제점이 있었다.In addition, in the case of a large closed container, the gap between the locking flange of the container cover becomes large, and thus the tendency of the container cover to rise in the center direction due to the principle of the lever when locking with the bending of the container itself and the locking flange occurs. There was a problem in that the local lifting phenomenon occurs in the gap between the locking flange of the cover to reduce the sealing.

또한, 대형 밀폐용기의 경우에는 용기커버 자체의 변형(휨, 뒤틀림 등)과 패킹의 자중으로 인해 용기커버를 탈착할 때에 패킹이 빈번히 이탈되는 문제점이 있으며, 패킹의 조립상태에 변형이 발생하게 되면, 패킹의 처짐 및 뒤틀림으로 인한 단면적의 불규칙적인 감소, 패킹이 삽입되는 시일링홈에 이물삽입우려, 내구력 저하, 용기커버의 개폐작업성 저하 등의 여러가지 문제점이 발생하게 된다.In addition, in the case of large closed containers, the packing is frequently detached when the container cover is detached due to the deformation (bending, warping, etc.) of the container cover itself and the weight of the packing. If the deformation occurs in the assembly state of the packing, , Irregular reduction of the cross-sectional area due to sagging and twisting of the packing, foreign matters inserted into the sealing groove into which the packing is inserted, lowering durability, lowering the opening and closing workability of the container cover will occur.

따라서, 본 발명은 상기 문제점을 해결하기 위해 이루어진 것으로서, 특히 대형 밀폐용기의 경우에 유체의 누설을 방지하는 밀폐용기의 밀폐장치를 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, and in particular, in the case of a large hermetic container, to provide a hermetic sealing device for preventing a leakage of a fluid.
