Description

내부압력 해제기능을 갖춘 음식물 보관용기용 밀폐뚜껑{A COVER FOR FOOD VESSEL}Sealing lid for food container with internal pressure release function {A COVER FOR FOOD VESSEL}

본 고안은 음식물 보관용기용 밀폐뚜껑에 관한 것으로, 더욱 상세하게는 음식물이 담겨진 보관용기를 견실하게 밀폐할 수 있으며 이를 개방시 내부압력(진공압)을 용이하게 해제할 수 있도록 『내부압력 해제기능을 갖춘 음식물 보관용기용 밀폐뚜껑』에 관한 것이다.The present invention relates to an airtight lid for a food storage container, and more specifically, to a food container containing a food container, which can be reliably sealed, and releasing the internal pressure (vacuum pressure) when it is opened 『internal pressure release function. It relates to a closed lid for food storage containers equipped with.

일반적으로 음식물을 보관하는 경우 자체의 독특한 냄새 및 수분이 유출됨으로써, 이를 방지하기 위해 음식물을 밀폐 보관용기에 담아 냉장고 등에 보관한다. 이러한 종래 밀폐 보관용기는 상부가 개방된 용기본체와, 이 용기본체를 개폐하는 뚜껑과, 이 뚜껑을 용기본체의 개방부에 잠그기 위한 잠금손잡이를 갖추고 있다.In general, when the food is stored, its own smell and moisture is leaked out, and in order to prevent this, food is stored in a sealed container and stored in a refrigerator. Such a conventional hermetic storage container is provided with a container body with an open top, a lid for opening and closing the container body, and a locking knob for locking the lid to an opening of the container body.

용기본체는 통상 사각 또는 원형으로 이루어져 있어서, 내부에 저장공간이 형성된다. 또한, 용기본체의 개방단부에는 잠금돌기가 마련되는데, 이 잠금돌기들은 용기본체 측벽의 외면을 따라 각각 돌출되게 형성된다.The container body is usually made of a square or circle, the storage space is formed therein. In addition, a locking protrusion is provided at the open end of the container body, and the locking protrusions are formed to protrude along the outer surface of the side wall of the container body, respectively.

뚜껑은 용기본체의 개방부를 여유있게 덮도록 판상으로 이루어지며, 이의 가장자리에는 실리콘패킹이 설치되도록 오목하게 패킹홈이 형성된다. 이에 따라 패키홈에 실리콘패킹이 끼운 상태에서 뚜껑을 덮으면, 실리콘 패킹과 용기본체의 개방단부가 밀착되게 된다. 그리고 잠금손잡이는 뚜껑의 네변에 각각 바깥측으로 선회 가능하게 일체로 이루어지며, 각각에는 잠금돌기와 대응하도록 잠금홀이 형성된다. The lid is formed in a plate shape so as to cover the opening of the container body with a margin, the packing groove is formed concave so that the silicon packing is installed at the edge thereof. Accordingly, when the lid is covered in the state in which the silicone packing is inserted into the package groove, the open end of the silicon packing and the container body is in close contact. And the locking handle is made integrally rotatably outward on each of the four sides of the lid, each lock hole is formed to correspond to the locking projection.

이에 따라 용기본체의 저장공간에 음식물을 넣고 뚜껑을 덮은 상태에서 잠금손잡이들을 각각 하측으로 내리 누르면, 용기본체에 마련된 잠금돌기가 잠금홀에 탄성 결합되어 뚜껑이 견실하게 잠긴다. 이 때, 패킹홈에 배치된 실리콘패킹은 용기본체의 개방단부에 접하면서 압착되어 내용물이 새는 것을 방지한다.Accordingly, when food is put into the storage space of the container body and the locking knobs are pressed downward in the state in which the lid is covered, the locking protrusions provided in the container body are elastically coupled to the locking holes so that the lid is securely locked. At this time, the silicon packing disposed in the packing groove is pressed while contacting the open end of the container body to prevent the contents leak.

그러한 이러한 종래 밀폐 보관용기에서는 용기본체의 내부압력과 대기압과의 압력차이로 인해 잠금손잡이를 상측으로 들어올려 록킹상태를 해제하여도 뚜껑 개방이 쉽게 이루어지지 않는다. 즉, 밀폐 보관용기를 냉장고의 같이 차가운 곳에 장시간 보관하면, 내부압력이 대기압보다 낮은 상태로 유지되는데, 이런 상태의 밀폐 보관용기를 꺼내 뚜껑을 갑작스럽게 개방하려 하면 대기압과의 기압차이로 인해 뚜껑 개방이 어려운 단점이 있으며, 이러한 현상은 밀폐 보관용기의 사이즈가 큰 경우가 더욱 심하다.In such a conventional hermetically sealed container, the lid is not easily opened even when the locking knob is lifted upward to release the locking state due to the pressure difference between the internal pressure of the container body and the atmospheric pressure. In other words, if the airtight container is stored in a cold place for a long time in the refrigerator, the internal pressure is kept lower than atmospheric pressure. If the airtight container is taken out of this state and the lid is suddenly opened, the airtight pressure is different from the atmospheric pressure. This is a difficult disadvantage, and this phenomenon is more severe if the size of the sealed container is larger.

또한, 종래 밀폐 보관용기는 뚜껑을 개방하지 않고 내부압력을 해제할 수 있는 별도의 구성이 없기 때문에, 뚜껑을 닫은 상태에서 전자렌지 등에 직접 조리용도로 사용할 수 없다.In addition, the conventional hermetically sealed container does not have a separate configuration capable of releasing the internal pressure without opening the lid, and thus cannot be used for cooking directly in a microwave oven or the like with the lid closed.

본 고안은 이러한 문제점을 해결하기 위한 것으로; 본 고안의 목적은 밀폐뚜껑에 밸브장치를 부설하여 음식물 보관용기의 내부압력이 대기압보다 낮은 상태에서도 밀폐뚜껑을 손쉽게 개방시킬 수 있는 내부압력 해제기능을 갖춘 음식물 보관용기용 밀폐뚜껑을 제공하는 것이다.The present invention is to solve this problem; An object of the present invention is to provide a sealed lid for a food storage container having an internal pressure release function that can easily open the sealed lid even when the internal pressure of the food storage container is lower than atmospheric pressure by installing a valve device on the sealed lid.

또한, 본 고안의 다른 목적은 밸브장치를 통해 밀폐뚜껑 개방을 용이하게 할 수 있는 것은 물론이며 밀폐력 역시 탁월하게 발휘할 수 있는 내부압력 해제기능을 갖춘 음식물 보관용기용 밀폐뚜껑을 제공하는 것이다.In addition, another object of the present invention is to provide a closed lid for a food storage container having an internal pressure release function that can facilitate the opening of the closed lid through the valve device, as well as excellent sealing force.

<본 고안에 따른 밀폐뚜껑의 밸브장치 작동 설명><Description of the operation of the valve device of the closed lid according to the present invention>

다음에는 이와 같이 구성된 본 고안에 따른 밀폐뚜껑의 밸브장치 작동 및 이에 따른 작용효과를 도 7 내지 도 9를 참조하여 설명한다.Next will be described with reference to Figures 7 to 9 the operation of the valve device of the closed lid according to the present invention configured as described above and the resulting effects.

먼저, 도 7에 도시한 바와 같이, 보관용기(10)의 저장공간에 보관하고자 하는 음식물(F)을 넣고 이의 개방부에 밀폐뚜껑(20)을 덮는다. 따라서 밀폐뚜껑(20)의 가장자리는 보관용기(10)의 개방부 외곽을 덮으며, 밀폐뚜껑(20) 하면의 패킹(23)은 보관용기(10)의 측벽 내면에 밀착된다. 즉, 패킹(23)의 밀착부(23a)가 탄성 변형되면서 보관용기(10)의 측면 내면에 밀착된다. 이러한 밀폐뚜껑(20)을 덮는 과정에서 보관용기(10)내의 공기 일부는 연통홈(143) → 승하강-가이드부(110)와 하부밸브체(140) 하부샤프트부(141)와의 사이틈 → 배기홈(112)을 통해 외부로 빠져나감으로써, 밀폐뚜껑(20)을 용이하게 덮을 수 있다(도 7의 점선 화살표 방향).First, as shown in Figure 7, put the food (F) to be stored in the storage space of the storage container 10 and covers the sealing lid 20 in its opening. Therefore, the edge of the sealing lid 20 covers the outer edge of the opening of the storage container 10, the packing 23 of the bottom of the sealing lid 20 is in close contact with the inner surface of the side wall of the storage container (10). That is, the close contact portion 23a of the packing 23 is in close contact with the inner surface of the side surface of the storage container 10 while being elastically deformed. Part of the air in the storage container 10 in the process of covering the sealing lid 20 is the communication groove 143 → the gap between the elevating-guide portion 110 and the lower valve body 140, the lower shaft portion 141 → By exiting through the exhaust groove 112 to the outside, it is possible to easily cover the sealing lid 20 (in the direction of the dashed arrow in Figure 7).

그리고 도 8에 도시한 바와 같이, 밀폐뚜껑(20)을 완전하게 덮고 밸브장치(100)의 상부밸브체(120)를 아래측으로 내리 누르면(화살표 A 방향), 승하강-가이드부(110)에서 상부밸브체(120)와 함께 하부밸브체(140)가 일체로 내려가게 된다. 이 때, 오-링(130)은 탄성 변형되면서 걸림테(111)를 넘어가 아래측에 위치됨으로써, 배기홈(112)을 차단한다. 따라서 보관용기(10)의 내부는 대기와 완전하게 차단된 상태로 유지된다. 이 때, 밸브장치(100)의 하강이동은 오-링(130)이 탄성변형되면서 걸림테(111)를 억지로 넘어가기 때문에, 하강정도는 사용자가 용이하게 인지할 수 있다.As shown in FIG. 8, when the upper lid 100 of the valve device 100 is completely covered with the sealing lid 20 completely lowered (arrow A direction), the lifting and lowering-guide part 110 is removed. The lower valve body 140 descends together with the upper valve body 120. At this time, the O-ring 130 is positioned below the latch frame 111 while being elastically deformed, thereby blocking the exhaust groove 112. Therefore, the inside of the storage container 10 is maintained in a state completely blocked from the atmosphere. At this time, the lowering movement of the valve device 100, because the O-ring 130 is elastically deformed and the locking frame 111 is forcibly crossed, the lowering degree can be easily recognized by the user.

따라서 밸브장치(100)를 통해 배기홈(112)을 개방하지 않고 밀폐뚜껑(20)을 인위적으로 개방할려고 할수록 보관용기(10)의 내부에는 진공압이 발생되며, 이로 인해 패킹(23)의 밀착부(23a)는 보관용기(10) 내면에 보다 밀착된 상태로 유지된다.Therefore, the artificial pressure to open the airtight lid 20 without opening the exhaust grooves 112 through the valve device 100 generates a vacuum pressure inside the storage container 10, and thus close packing of the packing 23. The part 23a is maintained in a state of being in close contact with the inner surface of the storage container 10.

한편, 밀폐뚜껑(20)을 개방하고자 하는 경우에는 상부밸브체(120)의 손잡이부(123)를 잡고 이를 상측으로 들어올린다(도 1참조). 상부밸브체(120)의 상측이동은 하부밸브체(140)의 스톱퍼부(142)가 뚜껑본체(21) 하면에 닿을 때까지 이루어진다. 이와 같이, 밸브장치(100)를 상측으로 들어올려 오-링(130)을 걸림테(111) 상측에 위치시키면, 승하강-가이드부(110)의 배기홈(112)과 연통홈(143)을 통해 보관용기(10) 내부와 대기가 연통된다. 따라서 밀폐뚜껑(20)을 개방하는 과정에서 대기중의 공기가 밀폐뚜껑(20)의 배기홈(112)과 연통홈(143)을 통해 보관용기(10) 내부로 유입되며, 이로 인해 밀폐뚜껑(20)을 용이하게 개방할 수 있다.On the other hand, if you want to open the closed lid 20, hold the handle portion 123 of the upper valve body 120 and lift it upwards (see Fig. 1). The upper movement of the upper valve body 120 is made until the stopper portion 142 of the lower valve body 140 touches the lower surface of the lid body 21. As such, when the valve device 100 is lifted upward and the o-ring 130 is positioned above the latch frame 111, the exhaust groove 112 and the communication groove 143 of the elevating-guide part 110 are positioned. Through the storage container 10 and the atmosphere is communicated through. Therefore, air in the atmosphere is introduced into the storage container 10 through the exhaust groove 112 and the communication groove 143 of the sealed lid 20 in the process of opening the sealed lid 20, thereby closing the sealed lid ( 20) can be easily opened.

한편, 본 고안에 따른 밀폐뚜껑(20)을 이용하면 보관용기(10)에 음식물(F)이 담겨진 상태 그대로 전자레인지를 통한 직접 조리가 가능하다. 즉, 본 고안에 따른 밀폐뚜껑(20)을 통해 닫힌 음식물 보관용기(10)를 직접 전자레인지에 넣고 이를 동작시키면, 음식물 보관용기(10) 내부에서는 음식물(F)이 조리되면서 수증기가 발생되고 내부압력이 대기압보다 높아진다. 이러한 보관용기(10)의 내부압력은 도 9에 도시한 바와 같이, 포핏밸브유닛(200)의 탄성부재(230;코일스프링)의 탄성 지지력을 이기면서 압력플레이트(220)를 상측으로 들어올림과 동시에 밸브홀(124)에 배치된 밸브몸체(210)를 상측으로 들어올린다(도 9의 화살표 B 방향 참조). 따라서 밸브몸체(210)의 밸브헤드부(212)가 밸브홀(124)의 밸브시트부(124b)로부터 떨어지면서 밸브홀(124)이 개방되고, 이로 인해 보관용기(10)의 내부압력이 외부로 배출된다. 그리고 보관용기(10)의 내부압력이 대기압 수준으로 떨어지면, 탄성부재(230;코일스프링)의 탄성 지지력에 의해 밸브몸체(210)가 하강되어 밸브홀(124)을 다시 폐쇄한다.On the other hand, using the closed lid 20 according to the present invention it is possible to directly cook through a microwave oven in the state in which the food (F) is contained in the storage container (10). That is, when the closed food storage container 10 directly into the microwave oven through the airtight lid 20 according to the present invention and operate it, the food storage container 10 inside the food (F) while cooking steam is generated and The pressure is higher than atmospheric pressure. As shown in FIG. 9, the internal pressure of the storage container 10 lifts the pressure plate 220 upward while winning the elastic support force of the elastic member 230 (coil spring) of the poppet valve unit 200. At the same time, the valve body 210 disposed in the valve hole 124 is lifted upward (see arrow B direction in FIG. 9). Accordingly, the valve hole 124 is opened while the valve head portion 212 of the valve body 210 is separated from the valve seat portion 124b of the valve hole 124, thereby causing the internal pressure of the storage container 10 to be external. Is discharged. When the internal pressure of the storage container 10 drops to the atmospheric pressure level, the valve body 210 is lowered by the elastic support force of the elastic member 230 (coil spring) to close the valve hole 124 again.

결국, 보관용기(10)에서 밀폐뚜껑(20)을 개방하지 않고서도 전자레인지에 직접 넣어 음식물(F)을 안전사고 없이 조리할 수 있음으로써, 이의 사용 편리성이 월등하게 향상된다.As a result, the food container (F) can be cooked directly without a safety accident without opening the closed lid 20 in the storage container 10, thereby improving its convenience of use.
