따라서 본 발명은 종래의 문제점을 해결하고자 하는 것으로, 용기뚜껑의 상면을 누름으로써 용기 내부의 공기를 외부로 배출시켜 간단한 조작으로 용기 내부가 진공상태가 되도록 하여 저장된 음식을 장기간 보관할 수 있도록 하고자 한다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made in an effort to solve the conventional problems, and it is an object of the present invention to provide an apparatus and a method for discharging air inside a container by pressing the top surface of the container lid.

상기와 같은 목적을 달성하기 위하여 용기뚜껑을 경질의 합성수지로 성형하고 상기 용기뚜껑의 상면 테두리 부분 일측에는 용기 내부에 공기를 배출하는 체크밸브를 구비하고 상면의 중앙에는 뚜껑의 다른 부분보다 살두께를 얇게 가공하면서 상면으로 볼록하게 형성하여 펌프기능을 할 수 있는 누름부를 형성하여 누름부를 누름으로 용기내부의 공기를 간단하게 배출하여 용기내부를 진공상태가 되도록 한 것이다.In order to achieve the above object, the container lid is formed of a hard synthetic resin, and a check valve for discharging air into the container is provided at one side of the upper edge of the container lid. At the center of the upper surface, A pressing portion is formed so as to be convex on the upper surface while being thinly processed so that a pump function can be performed. By pushing the pressing portion, the air inside the container is simply discharged so that the inside of the container is evacuated.

또한 용기함체와 결합시 긴밀한 밀폐를 위해 용기뚜껑에 구비되는 패킹을 용기뚜껑의 테두리에 일체로 형성하거나 간단한 끼임으로 분리결합이 가능토록 하여 세척을 용이토록 한 것이다.In addition, the packing provided in the container lid is integrally formed on the rim of the container lid for tight sealing when the container lid is coupled with the container lid, or is separated from the container lid by a simple fitting.

따라서 본 발명은 별도로 구비되는 펌프를 사용하지 않고 뚜껑에 형성된 펌프기능을 하는 누름판을 손으로 직접 누름으로써 뚜껑에 형성된 체크밸브를 통해 용기 내부의 공기가 빠져나가도록 하여 밀폐용기를 간단한 조작으로 진공상태가 되도록 함으로써 사용의 용이성은 물론 취급이 용이하게 되는 것이다.Therefore, according to the present invention, the push plate, which functions as a pump, formed in the lid is directly pressed by a hand without using a separate pump, so that the air in the container is allowed to escape through the check valve formed in the lid, The ease of use as well as the ease of handling are facilitated.

또한 용기함체와 긴밀한 밀폐를 위해 용기뚜껑에 형성되는 패킹을 간단한 조작으로 분리결합토록 함으로써 용기의 세척을 용이하게 할 수 있게 되는 것이다.Further, the packing formed on the container lid is separated and coupled with a simple operation for close sealing with the container casing, thereby facilitating the cleaning of the container.

이하 첨부된 도면을 참조하여 본 발명의 구성과 효과를 상세하게 설명하면 다음과 같다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the structure and effects of the present invention will be described in detail with reference to the accompanying drawings.

도1 내지 도3에 도시된 바와 같이 본 발명은 용기함체(10)와 밀폐를 위해 하단 테두리에 패킹(160)이 구비된 용기뚜껑(20)으로 구성하고, 상기 용기뚜껑(20)의 상면은 테두리에서 내측으로 내입되어 용기함체(10) 내부의 공기가 빠져나가도록 상면에 통기공(22a)이 형성된 장착부(22)에 결합되는 체크밸브(23)와, 용기(10) 내부를 진공상태로 유도하는 펌프기능을 하는 누름부(21)와, 용기함체(10)에 밀폐를 위하여 상기 용기뚜껑(20)의 이면 테두리에 패킹(30)을 형성한 것이다.1 to 3, the present invention comprises a container lid 20 having a packing 160 at its lower edge for sealing the container lid 10, and the upper surface of the container lid 20 A check valve 23 coupled to a mounting portion 22 having a vent hole 22a formed on an upper surface thereof so as to allow the air inside the container housing 10 to escape from the rim of the container 10, And a packing 30 is formed on the rear edge of the container lid 20 for sealing the container enclosure 10.

이때 상기 용기뚜껑(20)은 경질의 합성수지로 성형되어지는 것이고, 상면에 형성된 누름부(21)의 누름작동을 위하여 상기 누름부(21)는 내입된 테두리에서 내측방향으로 살두께가 점점 얇게 형성하면서 상향으로 볼록하게 형성하여 누름이 가능토록 한 것이다.In order to press the pressing part 21 formed on the upper surface of the container lid 20, the pressing part 21 is formed to be gradually thinner in the inward direction from the inside edge of the container lid 20 So that it can be formed convex upward.

따라서 용기함체(10)에 용기뚜껑(20)이 패킹(30)에 의해 긴밀하게 결합된 상태에서 용기뚜껑(20)의 상면에 형성된 누름부(21)를 반복적으로 연속해서 누르면 용기함체(10) 내부의 공기가 체크밸브(23)를 통해 외부로 배출되어 용기내부가 진공이 걸려지게 되는 것이다.When the container lid 20 is tightly coupled to the container housing 10 by the packing 30 and the pressing portion 21 formed on the upper surface of the container lid 20 is repeatedly and continuously pressed, The inside air is discharged to the outside through the check valve 23, and the inside of the container is vacuumed.

또한 상기 볼록하게 형성된 누름부(21)의 중앙에는 누름작동이 용이하도록 중앙을 평평하게 형성하거나 내측으로 오목하게 형성한 누름면(21a)을 하여 손가락의 접촉면을 더 많게 하여 누름작동이 원활하면서도 용이토록 한 것이다.In addition, the center of the convexly formed pressing part 21 is formed flat at the center so as to facilitate the pressing operation or the pressing face 21a formed concavely inwardly to make the contact surface of the finger more smooth, That's it.

또한 상기 누름부(21)가 형성된 용기뚜껑(20)의 내입된 테두리면에는 단턱부(24)를 형성하여 누름부(21)가 누름작동될 때 누름부(21)만 눌려질 수 있도록 보강역할을 하게 되는 것이고, 상기 용기함체(10)의 바닥면이 누름부(21)의 누름면(21a)에 안착되어 밀폐용기를 다단으로 적층이 가능토록 하면서도 다단으로 적층된 밀폐용기가 임의로 쓰러지지 않고 안정적인 적층된 상태를 유지하게 되는 것이다.The stepped portion 24 is formed on the inner peripheral surface of the container lid 20 in which the pressing portion 21 is formed so that the pressing portion 21 can be pressed only when the pressing portion 21 is pressed, And the bottom surface of the container housing 10 is seated on the pressing surface 21a of the pressing portion 21 so that the hermetically sealed container can be stacked in multiple stages while the closed container stacked in multiple stages does not collapse arbitrarily, And the laminated state is maintained.

이때 용기함체(10)의 하단 모서리는 만곡되어 단턱부(24)에 닿지 않게 되고 바닥면에는 바닥테(11)가 형성되어 볼록하게 형성된 누름부(21)에 바닥테(11)가 밀착되어 안정적으로 적층이 되면서 간혹 외압에 의해 상단에 적층된 밀폐용기가 미끄러지더라도 단턱부(24)와 상면의 내입된 테두리 부분으로 용기함체(10)의 만곡된 모서리 부분이 밀착되어 살짝 기울어지고 완전히 넘어지지 않게 되는 것이다. At this time, the bottom edge of the container enclosure 10 is curved and does not touch the step 24, and the bottom frame 11 is formed on the bottom surface, and the bottom frame 11 is brought into close contact with the pressing portion 21, The curved edge portion of the container housing 10 is closely adhered to the rim portion of the upper surface of the step 24 and the inner surface of the upper surface of the upper surface of the container 24 to be slightly tilted and not completely collapsed .

그러나 상기에 상술되어진 밀폐용기의 적층구조가 본 발명의 목적을 제안하는 것은 아니고 다양한 적층형태로 적층이 가능한 것이다.However, the above-described laminated structure of the closed container does not suggest the object of the present invention, but can be laminated in various laminated forms.

이때 상기 누름부(21)의 일측으로 장착부(22)를 형성하여 체크밸브(23)가 장착되도록 하였고, 상기 장착부(22)는 상면의 하단으로 돌출되어 바닥면에 통기공(22a)이 형성되며, 상기 장착부(22)의 통기공(22a)이 형성된 하단 테두리에 통기로(22b)를 형성하고, 상기 체크밸브(23)는 장착부(22)의 통기공(22)보다 직경이 작고 길이가 긴 몸통(23a)과 상기 몸통(23a)을 중심으로 상단과 하단에 밀착편(23b,23c)이 형성되어 분리되지 않게 장착되는 것이다.At this time, a mounting portion 22 is formed at one side of the pushing portion 21 so that a check valve 23 is mounted. The mounting portion 22 protrudes to the lower end of the upper surface, and a vent hole 22a is formed on the bottom surface The check valve 23 is formed to have a smaller diameter than the vent hole 22 of the mounting portion 22 and a longer length than the vent hole 22 of the mounting portion 22. The vent hole 22b is formed at the lower end of the mounting portion 22, Tight fitting pieces 23b and 23c are formed on the upper and lower ends of the body 23a and the body 23a so that they are not detached.

따라서 이러한 체크밸브(23)는 평상시에는 상단에 위치된 밀착편(23b)이 장착부(22)의 관통공(22a)을 밀착시켜 밀폐토록 되고 하단의 밀착편(23c)은 장착부(22)의 하단으로 돌출된 통기로(22b)가 형성된 테두리선단과 떨어진 상태로 장착되어 진공을 걸기 위하여 누름부(21)를 누를 경우에는 용기내부가 누름에 의한 압력에 의해 내부공기가 체크밸브(23)가 승강되어 상단에 형성된 밀착편(23b)은 밀착된 상태에서 떨어지게 되고 하단에 형성된 밀착편(23c)은 통기로(22b)가 형성된 장착부(22)의 테두리선단에 밀착되면서 내부공기가 통기로(22b)를 통해 외부로 배출되고 내부공기가 배출되면 체크밸브(23)가 하강되어 상단의 밀착편(23b)이 통기공(22a)을 막게 되면서 진공이 걸려지게 되는 것이고, 진공을 해제하기 위하여 체크밸브(23)를 기울이면 상단의 밀착편(23b)이 벌려지면서 통기공(22a)을 통해 공기가 유입되어 진공이 해제가 되어 용기뚜껑(20)을 쉽게 분리할 수 있게 되는 것이다.Therefore, in the check valve 23, normally, the close contact piece 23b positioned at the upper end is brought into tight contact with the through hole 22a of the mount portion 22, and the close contact piece 23c at the lower end is closed at the lower end The check valve 23 is moved up and down by the pressure caused by the pressing of the inside of the container when the pressing portion 21 is pressed to attach the vacuum, And the close contact piece 23c formed at the lower end is brought into close contact with the edge of the mounting portion 22 in which the air passage 22b is formed so that the inner air flows into the air passage 22b, The check valve 23 is lowered so that the upper end close contact piece 23b closes the vent hole 22a and the vacuum is caught. In order to release the vacuum, the check valve 23 23 are tilted, the upper close contact piece 23b is tilted As the air is drawn in through the vent holes (22a), the vacuum is released is it is possible to easily separate the container lid (20).

또한 상기 체크밸브(23)와 누름부(21)가 형성된 용기뚜껑(20)의 상면의 어느 일측에는 통기공(25a)이 형성된 장착돌부(25)를 형성하고 상기 장착돌부(25)에 진공상태를 외부에서 확인토록 하는 튜브(26)를 끼임장착하여 누름부(21)의 펌핑작동으로 용기 내부의 공기가 체크밸브(23)를 통해 배출되어 용기 내부가 진공상태가 되면 진공압에 의해 튜브(26)가 찌그러짐이 발생되어 외부에서 쉽게 육안으로 용기의 진공상태를 식별할 수 있게 되는 것이다.A mounting protrusion 25 having a vent hole 25a is formed at one side of the upper surface of the container lid 20 on which the check valve 23 and the pressing portion 21 are formed and the mounting protrusion 25 is vacuum- The air in the container is discharged through the check valve 23 and the inside of the container is evacuated by the pumping operation of the pushing part 21. The tube 26 26 are distorted and the vacuum state of the container can be easily recognized from the outside with the naked eye.

상기 튜브(26)는 상단이 볼록하게 형성되어 장착돌부(25)에 끼워진 상태에서 튜브(26)의 볼록한 부분이 장착돌부(25)의 통기공(25a)이 형성된 상단보다 높게 형성되어 진공이 걸려지면 볼록한 부분이 찌그러지면서 장착돌부(25)의 상면에 밀착되는 구조이다.The convex portion of the tube 26 is formed to be higher than the upper end of the mounting projection portion 25 where the vent hole 25a is formed so that the tube 26 is caught by the vacuum The convex portion on the ground is pressed against the upper surface of the mounting projection portion 25 while being collapsed.

한편 본 발명에서는 밀폐용기(10)의 밀폐력을 우수토록 하기 위하여 용기뚜껑(20)의 이면테두리에 하향으로 돌출된 돌기테(27)를 형성하여 상기 돌기테(27)에 일체로 밀착면(31)과 밀착날개(32)로 이루어진 패킹(30)을 사출성형하였고, 상기 패킹(30)은 용기뚜껑(20)을 용기함체의 결합시 밀착날개(32)가 용기함체(10)의 내벽에 긴밀하게 밀착되어 밀폐구조를 갖게 되는 것이다.In order to improve the sealing performance of the closed container 10, a protruding frame 27 protruding downward from the rear edge of the container lid 20 is formed, and the protruding frame 27 is integrally formed with the close contact surface 31 The packing 30 is formed by injection molding the container lid 20 into the inner wall of the container enclosure 10 when the container lid 32 is engaged with the container enclosure So as to have a closed structure.

또한 상기 패킹(30)을 용기뚜껑(20)에서 탈,부착할 수 있도록 장착하여 세척을 용이하게 함으로써 위생적인 사용이 가능토록 한 것이다.Further, the packing 30 is mounted on the container lid 20 so as to be detachable so as to facilitate cleaning, thereby enabling hygienic use.

이를 위하여 상기 용기뚜껑(20)의 이면 테두리에 하향으로 돌출된 돌기테(27)에 끼워질 수 있도록 밀착면의 살두께를 두껍게 한 상태에서 밀착면에 끼임홈을 형성토록 하여 간단하게 끼임토록 하고 상기 패킹은 고무 또는 실리콘 재질로 이루어져 이러한 재질의 특성인 점착력의 우수성으로 긴밀한 끼임상태를 유지하여 임의로 분리되지 않게 되는 것이다.In order to achieve this, in order to fit the protruding protrusion 27 protruding downward on the rear edge of the container lid 20, the fitting surface is made thick so that the fitting surface is easily formed to fit the fitting surface Since the packing is made of rubber or silicone material, the packing is kept in a tight state due to the excellent adhesive property, which is a characteristic of the material, so that the packing is not arbitrarily separated.

한편 본 발명에서는 용기뚜껑(20)의 외형을 원형 또는 사각으로 형성할 수 있으며, 상기에 설명한 바와 같이 용기뚜껑(20)에 장착되는 체크밸브(23)와 튜브(26)의 위치가 한정되어지는 것은 아니다.In the present invention, the outer shape of the container lid 20 may be circular or rectangular, and the position of the check valve 23 and the tube 26 mounted on the container lid 20 may be limited It is not.

또한 상기 밀폐용기는 구조상으로 소규모 크기로 형성되어지고 반찬 등을 담을 수 있는 용기에 적용가능한 것이며, 상기 누름판(140)을 뚜껑(20)에 넓게 형성할수록 용기 내부를 진공상태로의 유도가 더욱 용이하게 되는 것이다. Further, the hermetically sealed container is formed in a small size in terms of structure, and is applicable to a container that can hold a side dish or the like. As the pressure plate 140 is formed wider on the lid 20, It will be done.

따라서 본 발명은 별도로 구비되는 펌프를 사용하지 않고 용기뚜껑(20)에 형성된 누름판(21)을 손으로 누름으로써 용기 내부에 공기가 빠져나가도록 하고 용기뚜껑(20)에 형성된 체크밸브(23)를 통하여 외부의 공기유입을 차단함으로써 용기 내부가 진공상태가 되어 저장된 반찬 등이 상하지 않고 장기간 보관될 수 있게 된다.Therefore, according to the present invention, by pushing the pressure plate 21 formed on the container lid 20 without using a separate pump, the air can be escaped into the container and the check valve 23 formed on the container lid 20 So that the inside of the container becomes a vacuum state, so that the stored side dishes can be stored for a long period of time without being damaged.
