Description

식품보관용기의 누름식 뚜껑{Press-type lid of food storage container}Press-type lid of food storage container}

본 발명은 식품보관용기에 관한 것으로, 더욱 상세하게는 연신 투명필름이 적용된 누름식 뚜껑을 통해 식품을 용이하게 밀폐 보관할 수 있으며 보관 식품의 확인이 용이한『식품보관용기의 누름식 뚜껑』에 관한 것이다.The present invention relates to a food storage container, and more specifically, to a “push-type lid for a food storage container,” which allows food to be easily sealed and stored through a push-type lid to which a stretched transparent film is applied and makes it easy to check the stored food. will be.

일반적으로 음식물(식품)을 냉장고 등에 보관하는 경우 자체의 독특한 냄새 및 수분이 유출됨으로써 이를 방지하기 위해 식품을 식품보관용기에 담아 보관한다. 이러한 종래 식품보관용기는 상부가 개방된 용기본체와, 이 용기본체를 개폐할 수 있도록 잠금날개가 마련된 뚜껑으로 이루어져 있다. 용기본체는 합성수지를 원료로 사각 또는 원 통 형태로 사출 성형되며 내부에 저장공간이 형성된다. 또한, 용기본체 측벽의 개방단부에는 잠금날개를 걸기 위한 걸림돌기가 돌출되게 마련된다. 그리고 잠금날개는 뚜껑의 가장자리를 따라 바깥측으로 선회 가능하게 일체로 이루어지며, 각각에는 걸림돌기에 걸릴 수 있도록 걸림턱이 마련된다. 따라서 용기본체의 상부에 뚜껑을 덮은 후 잠금날개들을 각각 아래측으로 내리누르면, 걸림턱이 용기본체의 걸림돌기에 탄성 결합되어 뚜껑이 견실하게 잠긴다. 그리고 잠금날개를 상측으로 들어올리면, 걸림턱 구속이 해제되어 뚜껑을 개방할 수 있다.In general, when food is stored in a refrigerator, etc., its unique odor and moisture leak out. To prevent this, the food is stored in a food storage container. These conventional food storage containers consist of a container body with an open top and a lid with a locking wing to open and close the container body. The container body is injection molded into a square or cylindrical shape using synthetic resin as a raw material, and a storage space is formed inside. Additionally, a locking protrusion for hanging the locking blade is provided to protrude from the open end of the side wall of the container body. Additionally, the locking wings are integrally formed so as to pivot outward along the edge of the lid, and each is provided with a locking protrusion so that it can be caught on a locking protrusion. Therefore, when the lid is placed on the upper part of the container body and each locking wing is pressed down, the locking protrusion is elastically coupled to the locking protrusion of the container body and the lid is securely locked. And when the locking wing is lifted upward, the locking jaw is released and the lid can be opened.

그러나 종래 식품보관용기에서는 뚜껑을 개폐하기 위해 잠금날개들을 내리누르거나 들어올려야 하는 불편함이 있으며, 대부분의 용기본체와 뚜껑이 불투명재질로 이루어져 있어서 보관된 식품을 육안으로 확인할 수 없다. 또한, 뚜껑이 잠긴상태에서 전자렌지에 식품보관용기를 넣고 간편 조리를 하는 경우 식품보관용기 내부압력이 상승하여 조리 중에 터질 염려가 있다. 따라서 전자렌지를 통해 밀폐식 식품보관용기에 담긴 식품을 조리하는 경우 반드시 뚜껑 일부를 개방해야 하는 사용상의 불편함이 있다.However, in conventional food storage containers, there is the inconvenience of having to press down or lift the locking wings to open and close the lid, and since most container bodies and lids are made of opaque materials, stored food cannot be visually confirmed. Additionally, when a food storage container is placed in a microwave oven with the lid locked and simple cooking is performed, the internal pressure of the food storage container increases and there is a risk that the food storage container may explode during cooking. Therefore, when cooking food in an airtight food storage container using a microwave, part of the lid must be opened, which is inconvenient.

본 발명은 이러한 문제점을 해결하기 위한 것으로; 본 발명의 목적은 연신 투명필름이 적용된 누름식 뚜껑을 통해 식품을 손쉽게 밀폐 보관할 수 있으며 뚜껑을 개방하지 않고서도 보관 식품을 육안으로 확인할 수 있는 『식품보관용기의 누름식 뚜껑』을 제공하는 것이다.The present invention is intended to solve these problems; The purpose of the present invention is to provide a “push-type lid for a food storage container” that allows food to be easily hermetically stored through a push-type lid with a stretched transparent film and allows the stored food to be visually inspected without opening the lid.

The reason why the edge member 210 is configured in a square frame shape is because the food storage container 100 is square, and the shape of the edge member 210 may also vary depending on the shape of the food storage container 100. In an embodiment of the present invention, the border member 210 is preferably injection molded integrally with the skirt member 220 using synthetic resin as a raw material.

스커트부재(220)는 테두리부재(210)에서 아래측으로 연장되어 식품보관용기(100)의 벽면(120) 안쪽을 따라 아래로 투입 배치되는 것으로, 도 2 내지 도 4에 도시한 바와 같이, 이의 하단부 가장자리에는 식품보관용기(100)의 벽면(120)과 밀착될 수 있도록 외향 플랜지 형태로 연장된 연질의 밀착패킹(221)이 이중사출공법을 통해 일체로 형성되어 있다. 밀착패킹(221)은 내측에서 외측으로 갈수록 그 두께가 점차 얇게 이루어져 있는데, 이것은 탄성 변형이 용이하게 이루어지면서 식품보관용기(100)의 벽면(120)에 보다 견실하게 밀착되도록 하기 위함이다. 이러한 밀착패킹(221)은 실리콘 또는 엘라스토마로 구성할 수 있다. 또한, 스커트부재(220)의 하단에는 개방부를 따라 연신 투명필름(230)의 가장자리가 끼워지는 끼움부(222)가 아래로 돌출되게 마련되어 있다. 이러한 스커트부재(220)는 상하 높이방향으로 신축이 가능한 주름형으로 이루어져 있는데, 이것은 식품보관용기(100)에 담긴 식품 양에 따라 신축되면서 식품보관용기(100)를 견실하게 밀폐시키기 위함이다.The skirt member 220 extends downward from the edge member 210 and is placed downward along the inside of the wall 120 of the food storage container 100. As shown in FIGS. 2 to 4, the lower end thereof At the edge, a soft close-fitting packing 221 extending in the form of an outward flange so as to be in close contact with the wall 120 of the food storage container 100 is formed integrally through a double injection method. The close-fitting packing 221 has a thickness that gradually becomes thinner from the inside to the outside. This is to facilitate elastic deformation and more securely adhere to the wall surface 120 of the food storage container 100. This close packing 221 may be made of silicone or elastoma. In addition, at the bottom of the skirt member 220, a fitting portion 222 into which the edge of the stretched transparent film 230 is inserted is provided to protrude downward along the opening portion. This skirt member 220 is made of a pleated shape that can expand and contract in the vertical and horizontal directions. This is to securely seal the food storage container 100 by expanding and contracting according to the amount of food contained in the food storage container 100.

또한, 도 5를 참조하면; 스커트부재(220)의 하단부 내측에는 식품보관용기(100)의 내부압력이 높아질 경우 이를 배출시키기 위한 배기홀(242)이 천공된 밸브안착부(240)가 마련되어 있다. 밸브안착부(240)는 스커트부재(220)의 하단부 내측에 수평방향으로 마련되며, 여기에는 밸브고정홀(241)을 중심으로 복수개의 배기홀(242)이 천공되어 있다. 그리고 밸브안착부(240)에는 배기홀(242)을 선택적으로 개폐하는 체크밸브(250)가 배치된다. 체크밸브(250)는 밸브안착부(240)의 밸브고정홀(241)에 상부에서 아래로 끼워져 고정되는 고정축(251)과, 고정축(151)의 상단에서 외향플랜지 형태로 연장되어 자체의 탄성 복원력으로 배기홀(242)들을 선택적으로 개폐하는 연질의 밸브플레이트(252)로 정의된다. 이러한 체크밸브(250)는 탄성 복원력이 우수한 연질의 고무(본 발명의 실시 예에서는 실리콘 재질로 구성됨)로 이루어져 있어서, 자체의 탄성력으로 배기홀(242)을 닫는 방향으로 복원된다. 즉, 식품보관용기(100)의 내부압력이 대기압보다 높은 경우 밸브플레이트(252) 가장자리 부위가 들려져 배기홀(242)이 개방되게 된다. 특히, 체크밸브(250)의 밸브플레이트(252)는 얇은 박막(멤브레인:MEMBRANE)으로 이루어져 있어서, 식품보관용기(100)의 내부압력 변화에 따라 배기홀(242) 개폐가 즉각적으로 이루어지게 된다. 또한, 체크밸브(250)의 고정축(251)은 밸브플레이트(252)의 중앙부위에서 아래측으로 길게 연장되며 중도에 걸림턱이 형성되어 있다. 이에 따라 고정축(251) 하단부를 밸브고정홀(241)에 가조립한 후 이를 아래측으로 잡아당기면, 고정축(251)의 걸림턱 부위가 탄성 변형되면서 밸브고정홀(241)에 끼워져 결합되면서 밸브플레이트(252)가 배기홀(242)을 덮게 된다.Also, referring to Figure 5; Inside the lower end of the skirt member 220, a valve seating portion 240 is provided with an exhaust hole 242 for discharging the internal pressure of the food storage container 100 when it increases. The valve seating portion 240 is provided in a horizontal direction inside the lower end of the skirt member 220, and a plurality of exhaust holes 242 are drilled with the valve fixing hole 241 as the center. And a check valve 250 that selectively opens and closes the exhaust hole 242 is disposed on the valve seating portion 240. The check valve 250 has a fixed shaft 251 that is fixed by being inserted downward from the top into the valve fixing hole 241 of the valve seating portion 240, and extends in the form of an outward flange from the top of the fixed shaft 151 to form its own. It is defined as a soft valve plate 252 that selectively opens and closes the exhaust holes 242 with elastic restoring force. This check valve 250 is made of soft rubber (in the embodiment of the present invention, made of silicone material) with excellent elastic recovery force, and is restored in the direction of closing the exhaust hole 242 by its own elastic force. That is, when the internal pressure of the food storage container 100 is higher than atmospheric pressure, the edge of the valve plate 252 is lifted and the exhaust hole 242 is opened. In particular, the valve plate 252 of the check valve 250 is made of a thin film (membrane: MEMBRANE), so that the exhaust hole 242 is immediately opened and closed according to changes in the internal pressure of the food storage container 100. In addition, the fixing shaft 251 of the check valve 250 extends long downward from the center of the valve plate 252 and has a stopping protrusion formed in the middle. Accordingly, when the lower part of the fixing shaft 251 is temporarily assembled in the valve fixing hole 241 and then pulled downward, the locking portion of the fixing shaft 251 is elastically deformed and inserted into the valve fixing hole 241 and coupled to the valve plate. (252) covers the exhaust hole (242).

그리고 연신(延伸) 투명필름(230)은 에틸렌 중합체 및 공중합체로 제조되며 투명성이 높고 늘어나면서 복원력이 우수한 필름으로, 도 2 내지 도 4에 도시한 바와 같이, 필름고정테(260)를 통해 스커트부재(220)의 끼움부(222)를 따라 고정된다. 즉, 연신 투명필름(230)의 가장자리를 스커트부재(220) 하단의 개방부를 따라 형성된 끼움부(222)에 위치시킨 후 필름고정테(260)를 요철결합방식으로 끼움 고정함으로써, 연신 투명필름(230)은 인위적인 힘이 가해지지 않는 한 수평상태로 유지된다.And the stretched transparent film 230 is made of ethylene polymer and copolymer and is a film with high transparency and excellent resilience when stretched. As shown in Figures 2 to 4, it is attached to the skirt through the film fixing frame 260. It is fixed along the fitting portion 222 of the member 220. That is, the edge of the stretched transparent film 230 is placed in the fitting portion 222 formed along the opening at the bottom of the skirt member 220, and then the film fixing frame 260 is fitted and fixed in a concavo-convex coupling manner, thereby forming the stretched transparent film ( 230) remains horizontal unless artificial force is applied.

다음에는 이와 같이 구성된 본 발명에 따른 누름식 뚜껑을 통해 식품보관용기를 눌러 밀폐하는 과정 및 이에 따른 작용효과를 도 6 내지 도 8을 참조하여 설명한다.Next, the process of pressing and sealing a food storage container through the push-type lid according to the present invention configured as described above and the resulting effect will be described with reference to FIGS. 6 to 8.

먼저, 도 6에 도시한 바와 같이, 식품보관용기(100)의 내부에 보관하고자 하는 식품(F)을 넣는다. 그리고 본 발명에 따른 누름식 뚜껑(200)을 식품보관용기(100)의 상부에서 아래로 밀어넣는다(도 6과 도 7의 화살표 방향 참조). 즉, 도 7에 도시한 바와 같이, 손잡이(211)를 잡고서 테두리부재(210)가 식품보관용기(100)의 벽면(120) 상단부를 따라 끼워져 결합될 때까지 스커트부재(220)를 식품보관용기(100) 내부에 밀어넣는다. 이때, 연질의 밀착패킹(221)이 식품보관용기(100)의 벽면(120)에 밀착되면서 미끄러져 내려가기 때문에, 식품보관용기(100)의 내부압력이 상승한다. 이러한 내부압력은 체크밸브(250)가 개방되어 외부로 빠져나간다.First, as shown in FIG. 6, food (F) to be stored is placed inside the food storage container 100. Then, the push-type lid 200 according to the present invention is pushed downward from the top of the food storage container 100 (see the arrow direction in FIGS. 6 and 7). That is, as shown in FIG. 7, hold the handle 211 and hold the skirt member 220 in the food storage container until the edge member 210 is inserted and coupled along the upper part of the wall 120 of the food storage container 100. (100) Push it inside. At this time, since the soft tight packing 221 slides down while being in close contact with the wall surface 120 of the food storage container 100, the internal pressure of the food storage container 100 increases. This internal pressure is released to the outside when the check valve 250 is opened.

즉, 연신 투명필름(230)으로 하단부가 폐쇄된 스커트부재(220)가 식품보관용기(100) 내부로 내려가 내부압력이 상승하면, 도 8에 도시한 바와 같이, 체크밸브(250)의 밸브플레이트(252) 가장자리가 들려 내부압력이 외부로 배출된다. 그리고 식품보관용기(100) 내부압력이 대기압 수준으로 내려가면, 체크밸브(250)의 밸브플레이트(252) 자체의 탄성력으로 복원되어 배기홀(242)들을 다시 닫는다. 또한, 도 7에 도시한 바와 같이, 스커트부재(220)가 식품보관용기(100) 내부로 투입됨에 따라 연신 투명필름(230)은 식품보관용기(100)에 담겨진 식품(F)과 접하면서 늘어나며, 이로 인해 식품보관용기(100)에 담긴 식품(F)은 연신 투명필름(230)으로 눌려져 그 위치가 고정된다. 그리고 체크밸브(250)의 밸브플레이트(252)를 인위적으로 들어올리면, 누름식 뚜껑(200)을 손쉽게 들어올려 개방시킬 수 있다.That is, when the skirt member 220, whose lower end is closed with the stretched transparent film 230, goes down into the food storage container 100 and the internal pressure increases, as shown in FIG. 8, the valve plate of the check valve 250 (252) The edge is lifted and the internal pressure is released to the outside. And when the internal pressure of the food storage container 100 falls to the atmospheric pressure level, the valve plate 252 of the check valve 250 is restored by its own elastic force and closes the exhaust holes 242 again. In addition, as shown in FIG. 7, as the skirt member 220 is introduced into the food storage container 100, the stretched transparent film 230 stretches while contacting the food (F) contained in the food storage container 100. , As a result, the food (F) contained in the food storage container (100) is pressed by the stretched transparent film (230) and its position is fixed. And by artificially lifting the valve plate 252 of the check valve 250, the push-type lid 200 can be easily lifted and opened.

또한, 본 발명에 따른 누름식 뚜껑(200)의 체크밸브(250)에서는 식품보관용기(100) 내부압력이 높아지면 자연배기가 가능하기 때문에, 식품보관용기(100)에 누름식 뚜껑(200)을 닫은 상태에서도 전자렌지를 통한 직접 조리가 가능하여 이의 사용 편리성이 월등하다. 즉, 전자렌지를 통한 조리시 식품보관용기(100) 내부압력이 높아질 수 있는데, 이러한 경우에도 체크밸브(250)를 통해 자연 배기가 이루어져 식품을 안전사고 없이 조리할 수 있다.In addition, in the check valve 250 of the push-type lid 200 according to the present invention, natural exhaust is possible when the internal pressure of the food storage container 100 increases, so the push-type lid 200 is installed on the food storage container 100. Even when the food is closed, direct cooking using the microwave is possible, so the convenience of use is superior. That is, when cooking using a microwave oven, the internal pressure of the food storage container 100 may increase. Even in this case, natural exhaust is achieved through the check valve 250, so food can be cooked without safety accidents.

이와 같이, 본 발명에 따른 누름식 뚜껑(200)을 식품보관용기(100)에 눌러 덮으면; 스커트부재(220)의 밀착패킹(221)이 식품보관용기(100)의 벽면(120) 안쪽을 따라 밀착되면서 내려가 식품보관용기(100)를 밀폐할 수 있으며, 연신 투명필름(230)을 통해 식품(F)을 용이하게 확인할 수 있다. 특히, 연신 투명필름(230)이 늘어나면서 식품보관용기(100)에 보관된 식품(F)을 고정시킴으로서, 이동이나 보관 중에 손상을 방지할 수 있다. 또한, 누름식 뚜껑(200)을 눌러 덮는 과정에서 식품보관용기(100) 내부공기가 대부분 체크밸브(250)를 개방시키면서 배기홀(242)을 통해 외부로 배출됨으로써 보관 식품의 산패를 최소화할 수 있다. 그리고 식품보관용기(100)의 내부압력이 높아지는 경우에도 체크밸브(250)가 자동으로 개방됨으로써, 누름식 뚜껑(200)을 개방하지 않고서도 전자렌지를 통한 간편 조리도 용이하게 할 수 있다.In this way, when the push-type lid 200 according to the present invention is pressed and closed on the food storage container 100; The close packing 221 of the skirt member 220 can be lowered in close contact with the inside of the wall 120 of the food storage container 100 to seal the food storage container 100, and the food storage container 100 can be sealed through the stretched transparent film 230. (F) can be easily confirmed. In particular, as the stretched transparent film 230 stretches, it secures the food F stored in the food storage container 100, thereby preventing damage during movement or storage. In addition, in the process of pressing and closing the push-type lid 200, most of the air inside the food storage container 100 opens the check valve 250 and is discharged to the outside through the exhaust hole 242, thereby minimizing rancidity of stored food. there is. In addition, even when the internal pressure of the food storage container 100 increases, the check valve 250 is automatically opened, making it possible to easily cook food using a microwave oven without opening the push-type lid 200.

한편, 본 발명에서는 누름식 뚜껑(200)의 스커트부재(220)가 상하 높이방향으로 신축이 가능한 주름 형상으로 이루어져 있어서, 식품보관용기(100)에 담긴 식품 양에 따라 신축되면서 식품보관용기(100)를 밀폐할 수 있다.Meanwhile, in the present invention, the skirt member 220 of the push-type lid 200 is made of a wrinkled shape capable of expanding and contracting in the up and down height directions, so that it expands and contracts according to the amount of food contained in the food storage container 100, thereby forming the food storage container 100. ) can be sealed.
