이하에 본 발명의 구성을 첨부한 도면을 참조하여 설명한다.The configuration of the present invention will be described below with reference to the accompanying drawings.

도 1은 본 발명에 의한 밀폐 용기 뚜껑의 패킹 고정 구조를 나타낸 단면도이며, 도 2는 본 발명의 패킹을 나타내는 저면도이고, 도 3은 본 발명 패킹의 요부 단면도이다.1 is a cross-sectional view showing a packing fixing structure of a sealed container lid according to the present invention, Figure 2 is a bottom view showing the packing of the present invention, Figure 3 is a sectional view of the main part of the packing of the present invention.

그리고 도 4는 본 발명의 패킹 고정부재를 나타낸 평면도이며, 도 5는 본 발명의 패킹 고정부재를 나타낸 정단면도이다.4 is a plan view showing the packing fixing member of the present invention, Figure 5 is a front sectional view showing the packing fixing member of the present invention.

도면에 있어 부호 1로 나타낸 밀폐 용기 뚜껑(1)의 저면(2)에는 일정 간격을 두고 동심을 이루는 2개의 수직벽(3)(4)이 돌출되어 있으며, 2개의 수직벽(3)(3) 사이에 링형의 장착요홈(5)이 형성되어 있다.On the bottom face 2 of the airtight container lid 1 indicated by reference numeral 1 in the drawing, two vertical walls 3 and 4 concentric are projected at regular intervals, and the two vertical walls 3 and 3 The ring-shaped mounting groove 5 is formed between the two poles.

상기 2개의 수직벽(3)(4)의 하단에는 패킹(6)이 위치하게 되는데, 이 패킹(6)은 고정면부(7)와 고정면부(7)로부터 경사지게 상승하여 용기본체(8)의 내벽면(9) 상측에 밀착하여 틈새를 밀봉하는 밀착면부(10)로 구성되고, 상기 밀착면부(10)에는 마치 골프공의 표면과 같이 공보 형상을 가지도록 작은 요홈들(11)이 형성되어 있으며, 이 작은 요홈(11)들은 부식에 의해 형성되거나 또는 금형에 의해 사출 성형시 형성되도록 할 수 있다.A packing 6 is positioned at the lower ends of the two vertical walls 3 and 4, and the packing 6 is inclined upwardly from the fixed surface portion 7 and the fixed surface portion 7 so that the container body 8 The inner wall surface (9) is in close contact with the upper surface portion 10 to seal the gap, the contact surface portion 10 is formed with small grooves (11) so as to have a publication shape as if the surface of the golf ball These small recesses 11 can be formed by corrosion or during injection molding by a mold.

그리고 상기 수평면으로 형성되는 고정면부(7)에는 상기 장착 요홈(5)의 폭에 상당하는 폭을 가진 호형상의 슬릿 구멍(12)이 전체 원호를 따라 일정간격으로 복수개가 형성되어 있다.In addition, a plurality of arc-shaped slit holes 12 having a width corresponding to the width of the mounting recess 5 are formed in the fixed surface portion 7 formed in the horizontal plane at regular intervals along the entire arc.

상기한 패킹(6)은 패킹고정부재(13)에 의해 고정되어지게 되는데, 패킹고정부재(13)에는 상기 호형상의 구멍(12)에 대응하여 그 구멍(12) 크기의 단면 형상을 가지는 복수개의 고정돌기(14)들이 수직으로 돌출 형성되어 있어, 상기 고정돌기(14)들이 패킹(6)의 호형슬릿구멍(12)을 통과하여 양측 수직벽(3)(4) 사이에 형성되는 링형 장착요홈(5)에 기밀하게 끼워져 장착되므로 패킹(6)의 외곽 부위인 고정면부(10)를 잡아 당기더라도 패킹(6)이 패킹고정부재(13)의 고정돌기(14)에 걸려 지지되므로 뚜껑(1)으로부터 이탈되는 일이 없게 된다.The packing 6 is fixed by the packing fixing member 13, and the packing fixing member 13 has a plurality of cross-sectional shapes having the size of the hole 12 corresponding to the arc-shaped hole 12. Two fixing protrusions 14 are formed to protrude vertically, so that the fixing protrusions 14 pass through the arc-shaped slit holes 12 of the packing 6 and are formed between the two vertical walls 3 and 4. Since the airtightly fits into the recess 5 and is pulled out, the packing 6 is supported by the fixing protrusion 14 of the packing fixing member 13 even when the fixing surface portion 10, which is an outer portion of the packing 6, is pulled out. It is not separated from 1).

이와같은 구성의 본 발명은 밀폐용기뚜껑(1)을 용기본체(8)에 닫고, 공기 연통 밸브(15)를 눌러 닫아 공기의 유통을 차단하게 되면, 패킹(6)의 밀착면부(10)가 용기본체(8) 내벽면(9)에 눌려지면서 밀착하여 틈새를 완전히 밀봉하게 되므로, 뚜껑(1)을 열려고 시도하더라도 용기본체(8)내부에 진공이 형성되기 때문에 열려지지 않게 된다.According to the present invention having the above configuration, when the airtight valve 15 is closed on the container body 8 and the air communication valve 15 is closed by closing the air flow, the contact surface 10 of the packing 6 is closed. Since the container body 8 is pressed against the inner wall surface 9 so as to close the gap completely, even if an attempt is made to open the lid 1, a vacuum is formed inside the container body 8 so that it cannot be opened.

따라서 만일 뚜껑(1)을 열고자 하면 공기 연통 밸브(15)을 들어 올려 개방하게 되며, 이로써 외부로부터 개방된 공기연통 밸브(15)를 거쳐 외부 공기가 용기본체(8)내로 유입되기 때문에 용기 내부에 진공이 형성되지 않아서 뚜껑(1)이 쉽게 탈거되는 것이다.Therefore, if the lid 1 is to be opened, the air communication valve 15 is lifted up and opened, thereby allowing the outside air to flow into the container body 8 through the air communication valve 15 opened from the outside. The vacuum is not formed in the lid 1 is easily removed.

그런데 여기서 본 발명의 중요한 특징은 패킹(6)의 밀착면부(10)가 부식처리에 의해 작은요홈(11)들이 형성되어 있어 그만큼 내벽면(9)과의 접촉면적이 작아지기 때문에 뚜껑(1)이 손쉽게 열려지게 되며, 내벽면(9)과의 밀착상태의 해제시 수많은 요홈(11)들이 충진된 공기로 인하여 쉽게 밀착 상태가 해제되면서 파열음의 발생도 방지하게 되는 것이다.By the way, the important feature of the present invention is that the contact surface portion 10 of the packing (6) is formed by the small grooves 11 are formed by the corrosion treatment, so that the contact area with the inner wall surface 9, the lid (1) This is easy to open, and when the release state of the close contact with the inner wall surface (9) is to be easily released due to the air filled with the numerous grooves 11 is to prevent the occurrence of the rupture sound.

이상과 같은 본 발명은 패킹에 복수개의 슬릿 구멍이 형성되고, 이 구멍을 관통하여 패킹 고정부재의 고정돌기가 뚜껑 저면에 형성된 링형 요홈에 기밀하게 끼워지면서 패킹을 눌러 고정시키므로써, 패킹고정부재를 분리해내지 않는 이상 패킹을 잡아당겨도 패킹이 분리되거나 밀림이 발생하는 일이 없게 되어, 뚜껑 장착시 패킹의 장착 위치 이탈로 인한 뚜껑 장착 불량 현상이 없어져 제품의 신뢰성을 제고하는 효과가 있다.In the present invention as described above, a plurality of slit holes are formed in the packing, and the packing fixing member is fixed by pressing the packing while the fixing protrusion of the packing fixing member is fitted into the ring-shaped groove formed on the bottom of the lid through the hole. If the packing is pulled out, the packing will not be separated or the rolling will not occur unless it is removed, and the lid is not mounted due to the deviation of the mounting position of the packing, thereby improving the reliability of the product.
