Description

식품보존용 밀폐용기{Airtight container for preserve food}Airtight container for preserve food

본 발명은 용기 내부의 공기를 외부로 배출시켜 용기와 뚜껑이 씰링부재를 통해 밀착되도록 한 식품 보존용 밀폐용기에 관한 것이다.The present invention relates to a closed container for food preservation to discharge the air inside the container to the outside to close the container and the lid through the sealing member.

일반적으로 각종 야채와 생선 등의 식품은 그 신선도의 유지가 매우 중요하며, 최소한 식품을 섭취하기 전까지는 변질되지 않은 상태로 유지되어야만 한다.In general, it is very important to maintain the freshness of various foods such as vegetables and fish, and at least until food is consumed, it must be kept intact.

식품의 변질은 외기와 접촉되는 상태에서 일정 시간을 방지시키게 되면 식품에 공기 중에 포함되어 있는 미생물이나 기타 유해 물질들이 접촉하면서 쉽게 산화되면서 변질이 이루어지게 된다.When the food is prevented from being in contact with the outside air for a certain time, the food is easily oxidized as the microorganisms or other harmful substances contained in the air come into contact with the food.

이런 식품 중에서 특히 발효식품은 반대로 미생물의 증식에 의해 더욱 활성화되어야만 하는 식품이지만 식품의 발효 및 숙성 속도가 지나치게 빨리 진행되면 보존성이 좋지 못하게 되는 폐단이 있다.Of these foods, especially fermented foods, on the contrary, foods that must be activated more by the growth of microorganisms, but if the fermentation and fermentation rate of the food proceeds too fast, there is a disadvantage that becomes poor storage.

따라서 식품의 발효 및 부패를 보다 지연시키기 위해서는 외부 공기와의 접촉이 차단되도록 하는 것이며, 이를 위해 제안된 것이 밀폐 용기가 알려져 있다.Therefore, in order to further delay the fermentation and decay of the food is to block the contact with the outside air, the proposed container for this is known.

도 1에 도시된 바와 같이, 종래의 식품 보존용 밀폐용기로서 국내 등록실용신안 제20-0424953호가 널리 알려져 있다. 이 식품 보존용 밀폐용기는 일정 크기의 수용 공간을 갖는 용기(10)와, 상기 용기(10)의 개방된 상부면을 커버하는 뚜껑(20)과, 상기 뚜껑(20)의 상부면 중앙에는 용기의 내부에 진공압이 형성될 수 있도록 하는 펌핑수단(30)과, 진공압 상태를 해제시킬 수 있는 진공압 제거부재(40)와, 상기 뚜껑(20)을 닫았을 때 용기(10)와 밀착되도록 뚜껑(20)의 단부를 따라 부착되어진 씰링부재(50)로 구성되어 있다.As shown in Figure 1, the domestic registered utility model No. 20-0424953 is widely known as a conventional container for food preservation. The food preservation container includes a container 10 having a storage space of a predetermined size, a lid 20 covering an open upper surface of the container 10, and a container in the center of the upper surface of the lid 20. Pumping means 30 to allow a vacuum pressure to be formed in the interior, a vacuum pressure removing member 40 to release the vacuum pressure state, and close the container 10 when the lid 20 is closed It consists of a sealing member 50 is attached along the end of the lid 20 so as to.

한편, 도 2에 도시된 바와 같이, 용기(10)와, 상기 용기(10)의 개방된 상부면을 커버하는 뚜껑(20)과, 상기 뚜껑(20)의 상부에 설치되어 용기(10) 내부의 공기를 선택적으로 배출시키거나 인입시키는 체크밸브(60)와, 상기 뚜껑(20)을 닫았을 때 용기(10)와 밀착되도록 뚜껑(20)의 단부를 따라 부착되어진 씰링부재(50)로 구성된 밀폐용기도 알려져 있다.Meanwhile, as shown in FIG. 2, the container 10, a lid 20 covering the open top surface of the container 10, and an upper portion of the lid 20 are installed inside the container 10. A check valve 60 for selectively discharging or drawing air in the air, and a sealing member 50 attached along the end of the lid 20 to be in close contact with the container 10 when the lid 20 is closed. Sealing containers are also known.

이러한 밀폐용기는 도 1과 같이 용기 내부를 진공상태로 만들 수는 없지만 용기 내부를 대기압보다 낮은 압력상태로 만들어서 강한 밀폐력을 갖도록 함으로서 진공용기와 대등한 음식보존 효과를 기대할 수 있도록 되어 있다.Such a sealed container can not make the inside of the container in a vacuum state as shown in FIG. 1, but by making the inside of the container a pressure lower than atmospheric pressure to have a strong sealing force, it is possible to expect a food preservation effect equivalent to that of a vacuum container.

즉, 상기 체크밸브(60)의 내부에는 용기(10)의 내부와 외부를 연통시키는 연통공(61)이 있고, 연통공(61) 내부에는 승강시 연통공(61)이 개방되도록 볼(62)이 설치되어 있는데, 조리시 용기(10)의 온도가 상승되면 용기(10)의 내부압력의 증가로 볼(62)이 상승하면서 팽창된 용기(10)의 내부공기가 외부로 배출된다. 그리고 조리후에는 볼(62)이 하강하여 연통공(61)을 막은 상태에서 용기(10)가 식게 되며 그 결과 용기(10)의 내부에 잔존하는 공기들이 냉각수축하면서 자연스럽게 용기(10)와 뚜껑(20) 사이에 강한 밀폐력이 형성되는 것이다.That is, the inside of the check valve 60 has a communication hole 61 for communicating the inside and the outside of the container 10, the inside of the communication hole 61 when the elevating communication hole 61 to open the ball 62 When the temperature of the container 10 is increased during cooking, the ball 62 rises due to an increase in the internal pressure of the container 10 and the internal air of the expanded container 10 is discharged to the outside. After cooking, the bowl 62 descends to cool the container 10 in a state in which the communication hole 61 is blocked, and as a result, the air remaining in the container 10 cools and contracts, and the container 10 and the lid naturally. Strong sealing force is formed between (20).

그리고 용기(10)로부터 뚜껑(20)을 분리하고자 할 때, 체크밸브(60)를 잡아당기게 되면, 체크밸브(60)와 뚜껑(20) 사이에 틈새가 발생되고, 이 틈새로 외기가 침투하면서 밀폐력이 해제되므로 뚜껑(20)을 용이하게 개방할 수 있다.In addition, when the lid 20 is to be removed from the container 10, when the check valve 60 is pulled out, a gap is generated between the check valve 60 and the lid 20, and the outside air penetrates into the gap. Since the sealing force is released, the lid 20 can be easily opened.

그러나, 종래의 식품보존용 밀폐용기들은 모두 용기 내부가 밀폐상태이므로 외부와의 높은 기압차로 인해 시간이 지남에 따라 씰링부재를 통해 외기가 용기 내부로 침투할 수밖에 없다.However, all the conventional food preservation airtight containers are all sealed inside the container, and due to the high air pressure difference with the outside, the outside air has no choice but to penetrate into the inside of the container through the sealing member.

이는, 씰링부재와 용기와의 밀착상태가 아무리 우수하다 하더라도 외기와 용기 내부를 오로지 씰링부재로만 의존하고 있기 때문에 만일 씰링부재가 노후화되거나 씰링부재의 밀착단부에 결함이 있는 경우 외기가 침투하는 것을 막을 수 없기 때문이다.This prevents air from penetrating in case the sealing member is deteriorated or there is a defect in the sealing end of the sealing member because the sealing member and the container are dependent only on the outside member and the inside of the container, no matter how excellent the adhesion state between the sealing member and the container is obtained. Because you can't.

더군다나 씰링부재의 밀착단부에 먼지나 머리카락과 같은 불순물이 달라붙어 있는 경우, 상기 불순물들은 씰링부재와 용기와의 밀착면을 국부적으로 들뜨게 하면서 외기의 침입을 촉발시키게 된다.In addition, when impurities such as dust or hair adhere to the close end of the sealing member, the impurities trigger the invasion of the outside air while locally lifting the close contact surface between the sealing member and the container.

특히, 상기 씰링부재는 인체에 무해하면서 탄성력과 밀착력이 우수한 실리콘재질로 주로 제작되는 점을 감안할 때, 공기투과성이 있는 실리콘의 재질특성상 높은 밀폐압이 인가될 경우 외기가 미세하게나마 지속적으로 씰링부재를 투과하여 용기 내부로 침투하게 된다.In particular, in view of the fact that the sealing member is made of a silicone material which is harmless to the human body and is excellent in elasticity and adhesion, the sealing member is continuously kept in fine air even when a high sealing pressure is applied due to the material characteristics of the air permeable silicone. It penetrates and penetrates into the container.

따라서, 시간이 지남에 따라 용기 내부로 외기의 침입량이 증가하게 되고 이에 따라 밀폐압이 충분히 형성되지 않아 용기의 내부에 담긴 식품들을 신선하게 보관되지 못하게 되면서 제품의 신뢰도가 크게 떨어지게 되는 문제점이 있다.Therefore, as time passes, the amount of infiltration of outside air into the container is increased, and thus, the sealing pressure is not sufficiently formed, thereby preventing the food contained in the container from being freshly stored, thereby greatly reducing the reliability of the product.

본 발명은 상기한 문제점들을 해결하기 위해 안출된 것으로서, 씰링부재의 노후화나 결함으로 인해 용기 내부로 외기가 침투하거나 실리콘 재질로 제작된 씰링부재의 공기투과성질로 인한 용기 내부로의 외기의 침투하는 것이 방지되어, 장시간의 보관에도 용기 내부에 담긴 식품들을 장기간동안 신선하게 보존할 수 있게 되는 식품보존용 밀폐용기를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, the outside air penetrates into the container due to the aging or defect of the sealing member or to penetrate the outside air into the container due to the air permeability of the sealing member made of silicone material The purpose of the present invention is to provide an airtight container for food preservation that prevents food from being stored in the container for a long time, even if stored for a long time.

상기 목적을 달성하기 위해, 본 발명의 식품보존용 밀폐용기는 일정 크기의 수용 공간을 갖는 용기와 상기 용기의 개방된 상부를 커버하는 뚜껑과 상기 뚜껑의 가장자리부 내측을 따라 설치된 씰링부재를 구비하고, 용기 내부의 공기를 외부로 배출시켜 용기와 뚜껑이 씰링부재를 통해 밀착되도록 한 식품보존용 밀폐용기에 있어서; 상기 용기의 상단은 뚜껑의 가장자리부가 안착되도록 수평절곡부와 수직절곡부로 이루어진 테두리부를 구비하며, 상기 씰링부재는 상기 용기의 테두리부를 이루는 수직절곡부의 상단면과 상기 뚜껑의 상단에 동시 밀착되는 제1밀착부와, 상기 용기의 테두리부를 이루는 수직절곡부의 수직면의 상단과 밀착되는 밀착돌기를 가지며상기 뚜껑의 측단면에 밀착되도록 상기 제1밀착단부로부터 하향연장된 제2밀착부와, 상기 용기의 테두리부를 이루는 수평절곡부의 수평면과 상기 뚜껑의 하단면에 동시 밀착되도록 상기 제2밀착부로부터 수평연장된 제3밀착부와, 상기 제3밀착부로부터 하향연장된 수직면에서 상기 용기의 수직내벽면에 밀착되게 돌출되며 상기 용기와의 밀착면적을 극대화시키도록 밀착단부가 위를 향해 연장형성된 제4밀착부와, 상기 용기의 내부가 밀폐상태가 될 때 상기 제3밀착부와 제4밀착부와 용기의 내벽면에 의해 형성되는 외기차단영역부를 가지는 것을 특징으로 한다.In order to achieve the above object, the food preservation closed container of the present invention includes a container having a receiving space of a predetermined size, a lid for covering the open top of the container and a sealing member installed along the inner edge of the lid and In a closed container for food preservation, the air inside the container to the outside to close the container and the lid through the sealing member; The upper end of the container has an edge portion consisting of a horizontal bending portion and a vertical bending portion to seat the edge portion of the lid, the sealing member is in close contact with the upper surface of the vertical bending portion forming the edge of the container and the top of the lid at the same time A second contact part extended downward from the first contact end part so as to be in close contact with the side end surface of the lid, the contact part having a close contact with an upper end of a vertical face of the vertical bending part forming the edge of the container; A third contact portion horizontally extended from the second contact portion so as to be in close contact with the horizontal plane of the horizontal bending portion forming the bottom portion and the bottom surface of the lid, and a vertical inner wall surface of the container from the vertical surface extended downward from the third contact portion A fourth contact portion which protrudes to extend and the contact end portion extends upward to maximize the contact area with the container, and When the inside of the machine is in a closed state, characterized in that it has an external air blocking area portion formed by the third and fourth contact portion and the inner wall surface of the container.

상기와 같이 구성된 본 발명은 씰링부재가 용기에 밀착되는 제1밀착부 내지 제4밀착부를 구비하므로 총 4단계에 걸쳐 외기가 차단되는 매우 견고한 차폐구조를 갖게 될 뿐만 아니라, 용기 내부가 밀폐상태가 될 때 상기 제3,4밀착부와 용기의 내벽면에 의해 형성되는 외기차단영역부를 형성하게 되므로 씰링부재가 노후화되거나 씰링부재에 결함이 있는 경우 제1밀착부를 통해 외기가 침투한다 하더라도 침투한 외기는 외기차단영역부로 유입되면서 용기 내부로의 유입이 저지되므로 용기 내부에 담긴 식품들을 장기간동안 신선하게 보존할 수 있게 되는 효과가 있다.The present invention configured as described above is provided with a first contact portion to the fourth contact portion in which the sealing member is in close contact with the container not only has a very solid shielding structure in which the outside air is blocked in a total of four stages, the interior of the container is sealed When the sealing member is aging or there is a defect in the sealing member when the sealing member is aging or there is a defect in the sealing member, the outside air penetrates even if the outside air penetrates through the first adhesive part. Since the inflow into the outside of the container is prevented from flowing into the outside blocking area, the food contained in the container can be kept fresh for a long time.

특히, 용기 내부의 압력과 용기 내부와 외기차단영역부 간의 압력차가 크지 않기 때문에 외기차단영역부 내부의 공기가 제3,4밀착부를 투과하려는 힘이 작아서 외기차단영역부 내부의 공기가 제3,4밀착부를 투과하여 용기 내부로 침투하는 것이 최대한 억제되므로 실리콘으로 제작된 씰링부재가 공기투과 성질로 인한 외기의 유입을 최소화할 수 있는 효과가 있다.In particular, since the pressure inside the container and the pressure difference between the inside of the container and the outside air blocking zone portion are not large, the air inside the outside air blocking zone portion has a small force that penetrates the third and fourth close parts, and thus the air inside the outside air blocking zone portion is reduced to 3, 4 Since the penetration through the close contact with the inside of the container is suppressed as much as possible, the sealing member made of silicon has an effect of minimizing the inflow of outside air due to air permeability.

아울러, 제1밀착부와 제2밀착부의 밀착돌기에서 외기침입경로가 꺽이게 되므로 외기침입이 매우 어려워지는 효과가 있다.In addition, since the outside air intrusion path is bent in the close contact protrusion of the first and second close contact parts, the invasion of the outside air becomes very difficult.

또한, 수직절곡부의 하단에 제2밀착부의 하단과 밀착되는 밀착돌기가 더 형성된 경우, 총 5단계에 걸쳐 외기가 차단되므로 차폐선능이 더욱 향상될 뿐만 아니라, 상기 밀착돌기를 통해 제2밀착부 하단에서 제3밀착부측으로 외기침입경로가 꺽이게 되므로 외기침입이 매우 어려워지는 효과가 있다.In addition, when a close contact is formed in close contact with the bottom of the second close contact portion of the vertical bent portion, since the outside air is blocked in a total of five stages, the shielding ability is further improved, and the bottom of the second close contact through the close contact protrusion Since the outside air intrusion path is bent to the third contact portion side, the outside air invasion becomes very difficult.

본 실시예에서 상기 배기수단으로는 상기 뚜껑(20)의 상부에 설치되어 밀폐한 용기(10)의 내부를 외부로 배출시키거나 입입시키는 체크밸브(60)가 채용되었다. 그러나, 상기 배기수단은 종래의 펌핑수단 및 진공압 제거부재로 구성되어도 무방하다.In this embodiment, as the exhaust means, a check valve 60 which is installed at the upper portion of the lid 20 and discharges or enters the inside of the sealed container 10 to the outside is adopted. However, the exhaust means may be composed of a conventional pumping means and a vacuum pressure removing member.

본 실시예에서 상기 씰링부재(100)를 제외한 나머지 뚜껑(20)과, 용기(10), 체크밸브(60)들은 종래와 유사한 구성과 작용을 하므로 상세한 설명은 생략하기로 한다.In the present embodiment, except for the sealing member 100, the remaining lid 20, the container 10, the check valve 60 has a similar configuration and operation as the conventional description will be omitted.

본 발명을 구성하는 용기(10)의 상단은 뚜껑(20)의 가장자리가 안착되도록 수평절곡부(15a)와 수직절곡부(15b)로 이루어진 테두리부(15)를 구비하고 있다.The upper end of the container 10 constituting the present invention is provided with an edge portion 15 consisting of a horizontal bent portion 15a and a vertical bent portion 15b so that the edge of the lid 20 is seated.

상기 씰링부재(100)는 상기 뚜껑(20)을 닫았을 때 용기(10)와 밀착되도록 뚜껑(20)의 단부를 따라 설치된다. 상기 씰링부재(100)은 실리콘 재질로 제작된다. 실리콘은 어떠한 형태의 다른 탄성체 소재와도 비교할 수 없는 안정된 화학구조를 가지고 있으며, 부식성이 없고 산화되지 않는 화합물로서 내열, 내한, 전기절연, 화학적 안전성, 내마모성, 광택성, 풍부한 탄성 등 여러 가지 특성을 갖추고 있기 때문에 식품보존용 밀폐기의 차폐용으로 매우 적합하다.The sealing member 100 is installed along the end of the lid 20 to be in close contact with the container 10 when the lid 20 is closed. The sealing member 100 is made of a silicon material. Silicon has a stable chemical structure that is unparalleled with any other elastomeric material. It is a non-corrosive and non-oxidizing compound. It has many properties such as heat resistance, cold resistance, electrical insulation, chemical safety, abrasion resistance, glossiness and rich elasticity. It is very suitable for the shielding of food preservation sealers.

상기 씰링부재(100)는 제1밀착부(110) 내지 제4밀착부(140)를 구비한다.The sealing member 100 has a first contact portion 110 to the fourth contact portion 140.

상기 제1밀착부(110)는 씰링부재(100)의 최상단을 이루면서 용기(10)의 테두리부(15)를 이루는 수직절곡부(15b)의 상단면(15c)과 상기 뚜껑의 상단에 동시 밀착된다.The first contact portion 110 forms the uppermost end of the sealing member 100 and is in close contact with the upper end surface 15c of the vertical bending portion 15b constituting the edge portion 15 of the container 10 and the upper end of the lid. do.

상기 제2밀착부(120)는 상기 뚜껑(20)의 측단면에 동시 밀착되도록 상기 제1밀착부(110)로부터 하향연장된다. 아울러 상기 제2밀착부(120)는 용기(10)의 테두리부(15)를 이루는 수직절곡부(15b)의 수직면의 상부와 밀착되도록 상기 수직면을 향해 돌출된 밀착돌기(121)를 가진다.The second contact portion 120 is extended downward from the first contact portion 110 to be in close contact with the side end surface of the lid 20 at the same time. In addition, the second contact portion 120 has a contact protrusion 121 protruding toward the vertical surface so as to be in close contact with the upper portion of the vertical surface of the vertical bending portion 15b constituting the edge portion 15 of the container (10).

따라서, 상기 제2밀착부(120)는 밀착돌기(121) 이하의 부위에서 수직절곡부(15b)의 수직면과 일정거리 이격된 상태를 유지하게 된다. 이는 용기(10)에 뚜껑(20)을 덮었을 때 수직절곡부(15b)와 제2밀착부(120)와의 마찰력으로 인해 뚜껑(20)이 원활하게 닫히지 않게 되는 불편함을 최소화하기 위함이다.Therefore, the second close contact portion 120 maintains a state spaced apart from the vertical surface of the vertical bending portion 15b at a portion below the close contact protrusion 121. This is to minimize the inconvenience that the lid 20 does not close smoothly due to friction between the vertical bending portion 15b and the second contact portion 120 when the lid 20 is covered with the container 10.

상기 제3밀착부(130)는 용기(10)의 테두리부(15)를 이루는 수평절곡부(15a)와 상기 뚜껑(20)의 하단면에 동시 밀착되도록 상기 제2밀착부(120)로부터 수평연장된다.The third contact portion 130 is horizontal from the second contact portion 120 to be in close contact with the horizontal bending portion 15a constituting the edge portion 15 of the container 10 and the bottom surface of the lid 20 at the same time. Is extended.

상기 제4밀착부(140)는 상기 제3밀착부(130)로부터 하향연장된 수직면에서 용기(10)의 수직내벽면(12)에 밀착되게 돌출형성된다. 그리고, 상기 용기(10)와의 밀착면적을 극대화시키도록 밀착단부(141)가 위를 향해 연장형성된다.The fourth close contact portion 140 protrudes to be in close contact with the vertical inner wall surface 12 of the container 10 in a vertical plane extended downward from the third close contact portion 130. In addition, the close end 141 extends upward to maximize the close contact area with the container 10.

이와 같이 구성된 씰링부재(100)는 제1밀착부(110) 내지 제3밀착부(130)에 의해 뚜껑(20)의 가장자리를 따라 끼워져 설치될 수 있게 된다.The sealing member 100 configured as described above may be fitted along the edge of the lid 20 by the first contact part 110 to the third contact part 130.

따라서, 뚜껑(20)을 닫고 체크밸브(60)를 통해 용기(10)의 내부에 정상적인 밀폐압이 형성되면, 상기 씰링부재(100)의 제1밀착부(110)가 용기(10)의 수직절곡부(15b)의 상단면에 견고하게 밀착되므로 사용자는 육안으로 뚜껑(20)이 용기(10)에 밀착되었는지의 여부를 통해 용기(10)의 밀폐상태를 쉽게 파악할 수 있게 된다.Therefore, when the lid 20 is closed and the normal sealing pressure is formed inside the container 10 through the check valve 60, the first contact part 110 of the sealing member 100 is perpendicular to the container 10. Since the top surface of the bent portion 15b is firmly adhered, the user can easily grasp the closed state of the container 10 by visually checking whether the lid 20 is in close contact with the container 10.

아울러, 뚜껑(20)을 닫고 체크밸브(60)를 통해 용기(10)의 내부에 정상적인 밀폐압이 형성되면, 제1밀착부(110)와 제2밀착부(120)의 밀착돌기(121)가 수직절곡부(15b)에 밀착되는 동시에 제3밀착부(130)가 수평절곡부(15a)에 밀착되고 제4밀착부(140)는 용기(10)의 수직내벽면(12)에 밀착된다. 따라서, 씰링부재(100)와 용기(10)는 총 4개소에서 걸쳐 균일하게 밀착되면서 용기(10) 내부를 완전히 차폐시키게 된다. 이때, 제1밀착부(110)와 제2밀착부(120)의 밀착돌기(121)와의 연결부위가 직각으로 이루어져 있기 때문에 외기의 침입경로가 직각으로 꺽인 형태를 갖게 되어 외기침입이 매우 어려운 상태가 된다.In addition, when the normal sealing pressure is formed inside the container 10 through the check valve 60 by closing the lid 20, the contact protrusion 121 of the first contact portion 110 and the second contact portion 120. Is in close contact with the vertical bent portion 15b and at the same time the third close portion 130 The fourth bent portion 140 is in close contact with the horizontal bent portion 15a and is closely attached to the vertical inner wall surface 12 of the container 10. Therefore, the sealing member 100 and the container 10 are completely in close contact with each other in four places to completely shield the inside of the container 10. At this time, since the connection portion between the first contact portion 110 and the contact protrusion 121 of the second contact portion 120 is formed at right angles, the intrusion path of the outside air is bent at a right angle, which makes it difficult to invade the outside air. Becomes

한편, 상기 씰링부재(100)는 상기 용기(10) 내부가 밀폐상태가 될 때 상기 제3,4밀착부(130,140)와 용기(10)의 내벽면에 의해 형성되는 외기차단영역부(150)를 가진다. 상기 외기차단영역부(150)는 제3밀착부(130)와 제4밀착부(140)의 이격공간으로서, 외기를 수용하여 용기(10)의 내부로 직접 침투하지 못하도록 저지한다.On the other hand, the sealing member 100 is the outside air blocking region portion 150 formed by the third, fourth contact portion 130, 140 and the inner wall surface of the container 10 when the inside of the container 10 is in a sealed state Has The outside air blocking region portion 150 is a spaced space between the third contact portion 130 and the fourth contact portion 140, and blocks the outside air so as not to penetrate directly into the inside of the container 10.

한편, 도 5에 도시된 바와 같이, 상기 수직절곡부(15b)의 하단에는 제2밀착부(120)의 하단과 밀착되는 밀착돌기(15d)가 더 형성될 수도 있다. 이 경우, 뚜껑(20)이 완전히 닫히기 직전을 제외하고는 뚜껑(20)이 닫히는 과정에서 제2밀착부(120)와 상기 밀착돌기(15d)가 접촉되지 아니하므로 뚜껑(20)이 원활하게 닫히게 되는 동시에 씰링부재(100)와 용기(10)의 테두리부(15)와의 밀착부위가 한군데 더 추가되므로 밀폐성능은 더욱 향상되게 된다. 특히, 외기의 침입경로가 밀착돌기(15d)를 통해 제2밀착부(120)의 하단에서 제3밀착부(130)측으로 꺽이는 형태를 갖게 되므로 외기침입이 매우 어려운 상태가 된다.On the other hand, as shown in Figure 5, the lower end of the vertical bending portion (15b) may be further formed in close contact with the lower end of the second contact portion 120 (15d). In this case, except that immediately before the lid 20 is completely closed, the lid 20 is smoothly closed because the second contact portion 120 and the contact protrusion 15d do not contact each other in the process of closing the lid 20. At the same time, the sealing member 100 and the close contact portion of the edge portion 15 of the container 10 are added to one more place so that the sealing performance is further improved. In particular, since the intrusion path of the outside air has a form of bending from the lower end of the second contact part 120 to the third contact part 130 side through the contact protrusion 15d, it is very difficult to invade the outside air.

이와 같이 구성된 본 발명의 식품보존용 밀폐용기는 다음과 같은 원리에 의해 용기(10) 내부로 외기가 침투되는 것이 최대한 억제된다.The sealed container for food preservation of the present invention configured as described above is suppressed as much as possible from outside air penetrating into the container 10 by the following principle.

먼저, 뚜껑(20)을 닫은 상태에서 용기(10)를 잠시 가열하거나, 용기(10)가 가열된 상태에서 뚜껑(20)을 닫는다. 이렇게 하면, 시간이 경과함에 따라서 용기(10)가 식게 되는데, 용기(10)가 식으면서 용기(10) 내부의 공기가 수축하게 됨과 동시에 체크밸브(60)를 통해서 외기가 용기(10)의 내부로 유입되는 것이 차단되고 있는 상태이므로 용기(10) 내부에는 밀폐압이 형성된다. 이러한 밀폐압은 용기(10)가 식어감에 따라 점차로 강력해지며 이 과정에서 용기(10)와 실링부재(100) 사이의 밀착력도 강해진다.First, the container 10 is heated briefly while the lid 20 is closed, or the lid 20 is closed while the container 10 is heated. In this case, as the time passes, the container 10 cools. As the container 10 cools, the air inside the container 10 contracts, and at the same time, the outside air is supplied to the inside of the container 10 through the check valve 60. Since the inflow to the state is blocked, the sealed pressure is formed inside the container 10. This sealing pressure is gradually stronger as the container 10 cools, and in this process, the adhesion between the container 10 and the sealing member 100 also becomes strong.

그 결과, 본 발명의 식품보존용 밀폐용기는 씰링부재(100)의 제1밀착부(110)를 통해 외기가 1차로 차단되고 제2밀착부(120)의 밀착돌기(121)에 의해 외기가 2차로 차단되며 제3밀착부(130)에 의해 외기가 3차로 차단되고 제4밀착부(140)를 통해 외기가 4차로 차단되는 매우 견고한 차폐구조를 갖게 된다.As a result, the airtight container for food preservation of the present invention is primarily blocked by the outside air through the first contact portion 110 of the sealing member 100 and the outside air by the contact protrusion 121 of the second contact portion 120. It is blocked by the second and has a very solid shielding structure that the outside air is blocked by the third by the third contact portion 130, and the outside air by the fourth contact portion 140 is blocked fourth.

특히, 제4밀착부(140)의 밀착단부(141)가 위를 향해 연장형성된 관계로 밀폐압이 증가할수록 밀착단부(141)가 아래로 탄성변형되고, 결국 용기(10)의 수직내벽면(12)에 더욱 긴밀하게 밀착되면서 차폐력을 극대화시키게 된다.In particular, since the close end portion 141 of the fourth close portion 140 extends upward, as the sealing pressure increases, the close end portion 141 elastically deforms downward, resulting in a vertical inner wall surface of the container 10 ( Closer contact with 12) maximizes shielding power.

한편, 뚜껑(20)이 하강함에 따라서, 제1밀착부(110)와 제2밀착부(120) 사이에는 외기차단영역부(150)가 형성된다. 따라서, 씰링부재(100)가 노후화되거나 씰링부재(100)에 결함이 있거나 씰링부재(100)에 불순물이 묻어있는 경우 제1밀착부(110)와 제2밀착부(120)와 제3밀착부(130)를 통해 외기가 용기(10)의 내부로 침투한다 하더라도 침투한 외기는 외기차단영역부(150)로 유입되면서 용기(10) 내부로의 유입이 저지된다. 이와는 반대로 제4밀착부(140)와 용기(10)의 수직내벽면(12)과의 밀착상태가 불량해지더라도 제1밀착부(110)와 제2밀착부(120)와 제3밀착부(130)에 의해 외기가 용기(10) 내부로 유입되는 것을 충분히 막을 수 있다.On the other hand, as the lid 20 is lowered, the outside air blocking region portion 150 is formed between the first contact portion 110 and the second contact portion 120. Therefore, when the sealing member 100 is aging, the sealing member 100 is defective, or when the sealing member 100 has impurities, the first contact part 110, the second contact part 120, and the third contact part Even though the outside air penetrates into the inside of the container 10 through the 130, the infiltrating outside air is introduced into the outside air blocking area portion 150, thereby preventing the inflow into the inside of the container 10. On the contrary, even if the contact state between the fourth contact portion 140 and the vertical inner wall surface 12 of the container 10 becomes poor, the first contact portion 110, the second contact portion 120, and the third contact portion ( 130, the outside air may be sufficiently prevented from flowing into the container 10.

뿐만 아니라, 최초의 외기차단영역부(150)의 내부에는 공기가 포함되어 있으나, 용기(10)의 내부에 밀폐압이 형성되는 과정에서 외기차단영역부(150) 내부의 공기 상당부분이 용기(10) 내부로 유입되면서 외기차단영역부(150) 내부의 압력은 용기(10) 내부의 압력보다는 크고 용기(10) 외부의 압력보다는 작게 된다.In addition, although the air is included in the first outside air blocking region 150, a substantial portion of the air inside the outside air blocking region 150 is formed in the process of forming a sealed pressure in the inside of the container 10. 10) The pressure inside the outside air blocking area portion 150 is larger than the pressure inside the container 10 while being introduced into the inside, and smaller than the pressure outside the container 10.

따라서, 용기(10) 내부와 외기차단영역부(150) 간의 압력차가 크지 않으므로 외기차단영역부(150) 내부의 공기가 제3,4밀착부(130,140)를 투과하려는 힘이 작고, 그 결과 외기차단영역부(150) 내부의 공기가 제3,4밀착부(130,140)를 투과하여 용기(10) 내부로 쉽게 침투하려는 것을 최소화할 수 있게 된다.Therefore, since the pressure difference between the inside of the container 10 and the outside air blocking region portion 150 is not large, the force of the air inside the outside air blocking region portion 150 to pass through the third and fourth contact portions 130 and 140 is small, and as a result, the outside air The air inside the blocking area 150 may penetrate the third and fourth close parts 130 and 140 to easily penetrate the inside of the container 10.
