본 발명은 밀폐용기를 여닫는 뚜껑에 관한 것으로, 더욱 상세하게는 용기를 밀폐시키기 위해 뚜껑을 여닫을 때 발생되는 충격으로 인해 절첩라인부의 양측 단부에 발생되는 크랙현상을 최소화할 수 있으며, 이에 따라 밀폐용기의 내구성을 향상시킬 수 있는 밀폐용기의 뚜껑에 관한 것이다.The present invention relates to a lid for opening and closing a sealed container, and more particularly, it is possible to minimize the crack phenomenon generated at both ends of the folding line part due to the impact generated when opening and closing the lid to seal the container, accordingly It relates to a lid of the sealed container that can improve the durability of the.

주지된 바와 같이, 밀폐용기는 음식물을 담아서 밀폐시키는 것으로, 이러한 종래의 밀폐용기는 개방단부를 갖도록 상부가 개방되어 음식물이 담기는 용기와, 상기 용기의 개방된 상부를 밀폐시키는 뚜껑으로 구성된다.As is well known, a hermetic container is a food container for hermetic sealing. The conventional hermetic container includes a container in which an upper part is opened to contain food and a lid for sealing an open upper part of the container.

도 1을 참조하여 종래의 밀폐용기를 상세히 살펴보면, 상기 용기(10)와 상기 뚜껑(20) 사이에는 실(30)이 설치되어 용기(10)를 기밀히 밀폐시키고, 상기 용기(10)에는 개방단부(11)의 외주면을 따라 록킹홈(12a)이 형성되도록 록킹림(12)이 구비되며, 상기 뚜껑(20)에는 상기 용기(10)의 록킹홈(12a)에 결합되도록 록킹돌기(21a)가 형성된 개폐손잡이(21)가 절첩라인부(22)로 연결된다. Referring to FIG. 1, a conventional sealed container is described in detail. A seal 30 is installed between the container 10 and the lid 20 to hermetically seal the container 10, and open the container 10. A locking rim 12 is provided to form a locking groove 12a along the outer circumferential surface of the end 11, and the lid 20 has a locking protrusion 21a to be coupled to the locking groove 12a of the container 10. Opening and closing handle 21 is formed is connected to the folding line portion (22).

따라서, 상기 용기의 개방단부(11)에 상기 실링(30)의 일면이 밀착되도록 상기 뚜껑(20)을 배치한 상태에서, 상기 개폐손잡이(21)를 절첩라인부(22)로 절첩시키면, 록킹돌기(21a)가 록킹홈(12a)에 결합되므로, 용기(10)의 개방단부(11)는 뚜껑(20)에 의해 밀폐된다.Therefore, when the lid 20 is arranged so that one surface of the seal 30 is in close contact with the open end 11 of the container, the opening / closing handle 21 is folded with the folding line portion 22, thereby locking. Since the projection 21a is coupled to the locking groove 12a, the open end 11 of the container 10 is closed by the lid 20.

여기서, 상기 용기(10)는 합성수지재 또는 유리재를 원료로 하여 성형되는데, 이같이 성형된 용기(10)는 분자와 분자 상호 간의 열적 상태변화에 따라, 형상과 치수가 수축되는 수축률이 반드시 일어나므로 제조된 용기(10)들은 치수가 정확히 일치하지 않게 된다. 즉, 도 1에서와 같이, 각각의 용기(10)들은 개방단부(11)와 록킹림(12) 저면 사이의 록킹구간(L)이 수축률에 따라 동일하게 형성되지 않으 므로, 일정한 공차범위 내의 록킹구간(L) 보다 두껍거나 또는 얇게 용기가 형성되는 것이다.Here, the container 10 is formed of a synthetic resin material or a glass material as a raw material, and thus the molded container 10 has a shrinkage rate that shrinks in shape and dimensions according to a thermal state change between molecules and molecules. The manufactured containers 10 do not exactly match the dimensions. That is, as shown in Figure 1, each of the containers 10, because the locking section (L) between the open end 11 and the bottom of the locking rim 12 is not formed equally according to the shrinkage rate, locking within a certain tolerance range The container is formed thicker or thinner than the section (L).

이때, 상기 록킹구간(L)이 얇게 이루어진 경우, 일정한 범위 내에서 탄성변형되는 실(30)에 의해 용기(10)를 뚜껑(20)으로 밀폐시키는데 지장이 없게 된다.At this time, when the locking section (L) is made thin, there is no problem to seal the container 10 with the lid 20 by the seal 30 elastically deformed within a certain range.

그러나 이와는 다르게 상기 록킹구간(L)이 두껍게 이루어진 경우, 록킹홈(12a)으로 록킹돌기(21a)가 결합될 때 절첩라인부(22)가 급격히 변형되면서 결합되어 절첩라인부(22)에 크리프가 증대되며, 이로 인해 발생되는 충격이 절첩라인부(22)의 양측 단부에 집중적으로 전달되어 결국에는 그 양측 단부에서 크랙이 발생되는 것이다.Unlike this, however, when the locking section L is made thick, when the locking protrusion 21a is coupled to the locking groove 12a, the folding line portion 22 is rapidly deformed to be coupled to the crease to the folding line portion 22. Increased, and the resulting impact is concentrated on both ends of the folding line portion 22, and eventually cracks are generated at both ends thereof.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출한 것으로, 본 발명은 용기를 밀폐시키기 위해 뚜껑을 여닫을 때 발생되는 충격으로 인해 절첩라인부의 양측 단부에 발생되는 크랙현상을 최소화할 수 있으며, 이에 따라 밀폐용기의 내구성을 향상시킬 수 밀폐용기의 뚜껑을 제공하는데 그 목적이 있다.The present invention has been made to solve the conventional problems as described above, the present invention can minimize the crack phenomenon occurring at both ends of the folding line portion due to the impact generated when opening and closing the lid to seal the container, Accordingly, an object of the present invention is to provide a lid of a sealed container that can improve durability of the sealed container.

상기 목적을 달성하기 위해 본 발명은, 상부가 개방된 용기의 외주면에는 록킹홈을 형성하도록 록킹림이 구비되고, 합성수지재로 이루어져 용기를 밀폐시키도록 결합되는 뚜껑에는, 록킹홈에 결합되도록 록킹돌기가 형성된 복수개의 개폐손잡이가 절첩라인부로 연결되는 밀폐용기에 있어서, 상기 뚜껑의 외주면에는 절첩라인부에 연결되도록 외향으로 돌출된 복수개의 연결부를 일체로 형성하되, 상기 개폐 손잡이의 록킹돌기가 용기의 록킹홈으로 결합될 때, 절첩라인부의 양측 단부로 전달되는 충격을 분산시키면서 단면적이 탄성변형되도록, 절첩라인부와 인접된 연결부의 저면에는 충격분산홈을 형성하는 것이다.In order to achieve the above object, the present invention is provided with a locking rim to form a locking groove on the outer circumferential surface of the top of the open container, the lid is made of a synthetic resin material coupled to seal the container, locking projection to be coupled to the locking groove In the closed container is formed a plurality of opening and closing handles are connected to the folding line portion, the outer peripheral surface of the lid is formed integrally with a plurality of connection parts projecting outward so as to be connected to the folding line portion, the locking projection of the opening and closing handle of the container When combined with the locking groove, the impact dispersion groove is formed on the bottom of the connection portion adjacent to the folding line portion so that the cross-sectional area is elastically deformed while dispersing the impact transmitted to both ends of the folding line portion.

여기서, 상기 충격분산홈은, 연결부의 양측 단부에 절첩라인부의 길이방향을 따라 형성되거나, 연결부의 양측 단부를 연결하도록 절첩라인부의 길이방향을 따라 형성될 수 있다.Here, the impact dispersion groove may be formed along the longitudinal direction of the folding line portion at both ends of the connecting portion, or may be formed along the longitudinal direction of the folding line portion to connect both ends of the connecting portion.

이러한 상기 충격분산환홈은 탄성변형과 함께 충격을 효율적으로 분산시키도록 반원형의 단면구조로 이루어지는 것이 바람직하다.The impact dispersion ring groove is preferably made of a semi-circular cross-sectional structure so as to effectively distribute the impact with the elastic deformation.

이하에서는 첨부된 도면에 따라서 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

먼저 첨부된 도면을 살펴보면, 도 2는 본 발명의 실시예에 의한 용기와 뚜껑이 분해된 분해사시도, 도 3은 본 발명의 실시예에 의한 뚜껑의 정면도, 도 4는 본 발명의 실시예에 의한 뚜껑의 저면도이다.Referring to the accompanying drawings, Figure 2 is an exploded perspective view of the container and the lid according to the embodiment of the present invention exploded, Figure 3 is a front view of the lid according to an embodiment of the present invention, Figure 4 is an embodiment of the present invention Bottom view of the lid.

첨부된 도 2에 도시된 바와 같이 본 발명은, 개방단부(110)를 갖도록 상부가 개방되어 음식물이 담기는 용기(100)와, 상기 용기(100)의 개방된 상부를 밀폐시키도록 결합되는 뚜껑(200)을 포함한다.As shown in FIG. 2, the present invention includes a container 100 containing an open end portion 110 and containing food, and a lid coupled to seal an open upper portion of the container 100. 200.

도 2에서 용기(100)를 원통형으로 도시하고 뚜껑(200)은 용기(100)의 형상에 부합되도록 원판형으로 도시하였으나, 필요에 따라서 용기(100)를 육면체 등의 다면체로 형성하고 이러한 용기(100)에 부합되도록 뚜껑(200)을 형성할 수 있음을 분명히 밝혀 둔다.In FIG. 2, the container 100 is illustrated in a cylindrical shape, and the lid 200 is illustrated in a disc shape so as to conform to the shape of the container 100. However, the container 100 is formed of a polyhedron such as a cube if necessary, and the container ( It is clearly noted that the lid 200 can be formed to conform to 100).

도 2를 참조하여 용기(100)를 상세히 살펴보면, 용기(100)의 개방된 상부에는 개방단부(110)가 형성되어 실(300)의 저면이 밀착되고, 이 개방단부(110)의 외주면을 따라 록킹림(120)이 일체로 형성되는데, 이때 록킹림(120)에는 하부를 따라 록킹홈(122)이 형성된다.Referring to the container 100 in detail with reference to Figure 2, an open end 110 is formed in the open upper portion of the container 100 is in close contact with the bottom surface of the seal 300, along the outer peripheral surface of the open end 110 The locking rim 120 is integrally formed, and the locking rim 120 is formed along the lower portion of the locking rim 120.

이러한 용기(100)는 최근 이슈화된 환경호르몬의 유해성에 가장 관련성이 적은 유리 및 도자기의 재질을 원료로 하여 성형하는 것이 바람직하지만, 필요에 따라 용기제조에 널리 사용되는 폴리에틸렌(PE, Polyethylene) 또는 폴리프로필렌(PP, Polypropylene) 따위의 합성수지재를 원료로 하여 성형할 수 있음은 자명하다.The container 100 is preferably molded from materials of glass and ceramics, which are least relevant to the hazards of environmental hormones, which are recently issued. However, if necessary, polyethylene (PE) or poly is widely used for manufacturing containers. It is obvious that synthetic resin materials such as propylene (PP, Polypropylene) can be molded as raw materials.

상술한 용기(100)의 개방단부(110)를 밀폐시키는 뚜껑(200)에는, 저면 가장자리를 따라 실장착홈(230)이 형성되어 실(300)이 장착되고, 외주면에는 외향으로 돌출된 복수개의 연결부(214)가 등간격으로 나뉜 사분점에 형성되며, 이 연결부(214)에는 개폐손잡이(210)가 절첩라인부(212)로 연결되는데, 이러한 개폐손잡이(210)에는 뚜껑(200)의 록킹홈(122)에 결합되도록 록킹돌기(210a)가 형성된다.In the lid 200 which seals the open end 110 of the container 100 described above, a seal mounting groove 230 is formed along a bottom edge thereof so that the seal 300 is mounted, and a plurality of protrusions protruded outward on the outer circumferential surface thereof. The connecting portion 214 is formed in the quadrant divided into equal intervals, the opening and closing handle 210 is connected to the folding line portion 212, the connecting portion 214, the opening and closing handle 210, the locking of the lid 200 The locking protrusion 210a is formed to be coupled to the groove 122.

도 3 및 도 4를 참조하여 뚜껑을 살펴보면, 연결부(214)의 저면에는 절첩라인부(212)와 인접되게 충격분산홈(214a)이 형성되며, 이 충산분산홈(214a)은 연결부(214)의 양측 단부에 절첩라인부(212)의 길이방향을 따라 형성되는 것이 바람직하다. 또한, 이 충격분산환홈(214a)은 효율적으로 탄성변형되면서 충격을 분산시키도록 반원형의 단면구조로 이루어지는 것이 바람직하다.Referring to the lid with reference to FIGS. 3 and 4, the impact dispersion groove 214a is formed at the bottom of the connection portion 214 adjacent to the folding line portion 212, and the dispersion dispersion groove 214a is the connection portion 214. It is preferable to be formed along the longitudinal direction of the folding line portion 212 at both ends of the. In addition, the impact dispersion ring groove 214a preferably has a semi-circular cross-sectional structure so as to disperse the impact while elastically deforming efficiently.

이에 따라, 개폐손잡이(210)를 절첩라인부(212)로 절첩시켜 록킹홈(122)에 록킹돌기(210a)를 결합할 때, 절첩라인부(212)의 양측 단부로 전달되는 충격을 분산시키게 된다. 또한, 용기(100)의 개방단부(110)와 록킹림(120) 저면 사이의 록킹구간(L)이 두껍게 형성된 경우, 개폐손잡이(210)의 절첩에 의해 록킹돌기(210a)가 록킹홈(122)으로 무리하게 결합될 때, 충격분산홈(214a)의 단면적이 탄성변형되므로, 절첩라인부(212)의 급격한 변형을 방지하게 된다.Accordingly, when the opening and closing handle 210 is folded into the folding line portion 212 to couple the locking protrusion 210a to the locking groove 122, the shock transmitted to both ends of the folding line portion 212 is dispersed. do. In addition, when the locking section L between the open end 110 of the container 100 and the bottom of the locking rim 120 is formed thick, the locking protrusion 210a is locked by the folding handle 210. When coupled to force), the cross-sectional area of the impact dispersion groove 214a is elastically deformed, thereby preventing a sudden deformation of the folding line portion 212.

이러한 뚜껑(200)은 개폐손잡이(210)의 록킹에 의해 충격분산홈(214a)의 단면적이 탄성변형되도록, 적절한 탄성을 갖는 폴리에틸렌(PE) 또는 폴리프로필렌(PP) 따위의 합성수지재로 이루어져 사출성형된다.The lid 200 is formed of a synthetic resin material such as polyethylene (PE) or polypropylene (PP) having an appropriate elasticity so that the cross-sectional area of the impact dispersion groove 214a is elastically deformed by locking the opening and closing handle 210. do.

이와 같이 구성된 본 발명의 용기와 뚜껑이 결합되는 작용을 도 5a 내지 도 5d를 참조하여 상세히 설명하면 다음과 같다.When the container and the lid of the present invention configured as described above will be described in detail with reference to FIGS. 5A to 5D.

먼저, 도 5a에서와 같이 뚜껑(200)의 실링(300)을 용기(100)의 개방단부(110)에 접촉시킨 상태에서, 한 손으로는 뚜껑(200)을 누르고, 다른 손으로는 도 5a에 도시된 화살표방향으로 개폐손잡이(210)를 눌러서 절첩라인부(212)를 중심으로 절첩시킨다.First, in the state in which the sealing 300 of the lid 200 is in contact with the open end 110 of the container 100 as shown in FIG. 5A, one hand presses the lid 200, and the other hand shows FIG. 5A. By pressing the opening and closing handle 210 in the direction of the arrow shown in the folding line 212 to the center.

그러면, 개폐손잡이(210)의 록킹돌기(210a)는 도 5b에서와 같이 용기(100)의 록킹림(120) 측면에 접촉되고, 이어서 도 5c에서와 같이 록킹림(120)의 저면에 접촉되는데, 이때 충격분산홈(214a)은 탄성변형되어 단면적이 변화됨에 따라 절첩라인부(212)에 집중되는 크리프를 분산시키게 된다.Then, the locking projection 210a of the opening and closing handle 210 is in contact with the side of the locking rim 120 of the container 100, as shown in Figure 5b, and then in contact with the bottom surface of the locking rim 120 as shown in Figure 5c In this case, the impact dispersion groove 214a is elastically deformed to distribute creep concentrated in the folding line portion 212 as the cross-sectional area is changed.

계속해서 개폐손잡이(210)를 누르면, 도 5d에서와 같이 용기(100)의 록킹홈(122)으로 록킹돌기(210a)가 결합되면서 일정한 충격이 발생되고, 이 충격은 단 면적이 얇은 절첩라인부(212)의 양측 단부에 집중적으로 전달되며, 이같이 전달된 충격은 절첩라인부(212)와 인접한 연결부(214)의 충격분산홈(214a)을 통해 분산되므로, 반복적인 개폐손잡이(210)의 절첩에 의해 발생되는 크랙현상이 현저히 감소된다.When the opening and closing handle 210 is continuously pressed, as shown in FIG. 5D, the locking protrusion 210a is coupled to the locking groove 122 of the container 100, and a constant shock is generated. Concentrated and transmitted to both ends of the 212, and thus the impact transmitted is distributed through the impact distribution groove 214a of the connection line 214 adjacent to the folding line portion 212, the folding of the repeatedly opening and closing handle 210 The crack phenomenon caused by is greatly reduced.

따라서, 용기(100)의 성형 후 수축률이 발생되어 록킹구간(L)이 두껍게 이루어진 경우나, 반복적인 개폐손잡이(210)의 절첩에 의해 발생된 충격이 절첩라인부(212)로 전달되는 경우에, 충격분산홈(214a)에서 절첩라인부(212)로 집중되는 크리프 및 충격을 분산시키므로, 결국에는 내구성이 우수한 뚜껑을 제공하게 되는 것이다.Therefore, when the shrinkage rate is formed after the molding of the container 100 and the locking section L is made thick, or when the impact generated by the folding of the repeatedly opening and closing handle 210 is transmitted to the folding line part 212. To distribute the creep and impact concentrated in the folding line portion 212 in the impact dispersion groove 214a, in the end will provide a lid with excellent durability.

한편, 첨부된 도 6은 본 발명의 다른 실시예에 의한 뚜껑(200)의 저면도로서, 본 발명의 다른 실시예에 의하면, 상기 충격분환홈(214a)은 절첩라인(212)의 길이방향을 따라 연결부(214)의 양측 단부를 연결하도록 형성되는 것이다.Meanwhile, FIG. 6 is a bottom view of the lid 200 according to another embodiment of the present invention. According to another embodiment of the present invention, the impact recirculation groove 214a is a longitudinal direction of the folding line 212. Accordingly, it is formed to connect both ends of the connecting portion 214.

따라서, 개폐손잡이(210)의 절첩에 의해 록킹돌기(210a)가 용기(100)의 록킹홈(122)으로 결합될 때, 충격분산홈(214a)의 탄성변형구간이 보다 넓게 분포되어 급격한 변형에 의한 크리프현상을 효율적으로 분산시키게 된다.Therefore, when the locking protrusion 210a is coupled to the locking groove 122 of the container 100 by the folding of the opening / closing handle 210, the elastic deformation section of the impact dispersion groove 214a is more widely distributed to the sudden deformation. This effectively disperses creep phenomenon.

이상의 설명은 본 발명에 의한 하나의 바람직한 실시예를 설명한 것에 불과할 뿐이며, 본 발명은 상술한 실시예에 한정되지 않고 첨부된 청구범위 내에서 다양하게 변형하여 실시할 수 있음을 분명히 밝혀 둔다.The foregoing descriptions merely illustrate one preferred embodiment according to the present invention, and it is apparent that the present invention is not limited to the above-described embodiments and can be modified in various ways within the scope of the appended claims.

이상에서 살펴본 바와 같이 본 발명에 따르면, 용기의 수축률에 의한 록킹구 간이 두꺼운 경우, 또는 반복적으로 뚜껑을 여닫을 때 발생되는 충격이 절첩라인부로 전달되는 경우, 충격분산홈의 탄성변형 및 충격분산에 의해 절첩라인부의 양측 단부에서 시작되는 크랙현상을 현저히 감소시킬 수 있는 매우 유용한 효과가 있다.As described above, according to the present invention, when the locking section due to the shrinkage rate of the container is thick, or when the shock generated when the lid is repeatedly opened and closed is transmitted to the folding line portion, the elastic dispersion and the impact dispersion of the impact dispersion groove are performed. There is a very useful effect that can significantly reduce the crack phenomenon starting at both ends of the folding line portion.
