Description

밀폐용기 뚜껑{A cover of an airtight container}Airtight Container Cap {A cover of an airtight container}

본 고안은 밀폐용기에 관한 것으로, 특히 함체에 결합되는 뚜껑이 함체에서 발생되는 내압에 의하여 자연적으로 이탈되어지는 것을 방지토록 하고, 뚜껑에 형성되는 밀폐를 위한 테두리를 이중사출에 의한 연질로 형성할 경우에 함체와의 개폐시 유연성과 밀폐력은 물론 사출의 용이성을 동시에 만족토록 한 것이다.The present invention relates to a sealed container, in particular to prevent the lid coupled to the enclosure from being naturally separated by the internal pressure generated in the enclosure, and to form a soft edge by the double injection to form a rim for the closure formed on the lid In this case, it is to satisfy both flexibility and sealing force as well as ease of injection.

현재 이러한 2중사출에 의한 밀폐는 통상 접착과 밀착성이 우수한 토마라는 재질의 원료를 사용하여 성형토록 하고 있다.Currently, such double injection sealing is usually performed by using a raw material called Toma, which has excellent adhesion and adhesion.

그러나 이러한 토마를 원료로 테두리(110)를 뚜껑체(100)에 2중사출할 경우에는 통상 도5a내지 도5c에 도시된 바와 같이 뚜껑체(100)의 외주연으로 뚜껑체 보다 얇은 지지살(120)을 형성하고 상기 지지살의 상하로 테두리(110)를 도포토록 되는 형태로 사출성형하는 것이다.However, in the case of double injection of the edge 110 into the lid 100 using the toma as a raw material, as shown in FIGS. 5A to 5C, the support body 120 is thinner than the lid 120 as the outer periphery of the lid 100. ) And injection molding into a shape in which the edge 110 is doped with the support bar up and down.

그러나 이러한 것의 단점이 토마가 연질이기 때문에 성형된 이후에는 테두리를 지지해주는 것이 없어 내측으로 심하게 휘어짐으로 함체와의 결합에 문제점이 발생된다는 것이고 또한 이러한 연질의 것이 성형시 수축에 의한 치수의 변화로 원하는 밀폐력을 확보한다는 것이 여간 곤란한 것이 아니다.However, the disadvantage of this is that the toma is soft, so there is no support for the rim after being molded, so it is severely bent inward, causing problems in joining with the enclosure. Ensuring sealing force is not difficult at all.

따라서 이러한 휨의 문제점을 해결하기 위하여 통상 연질의 특성을 갖는 토마를 강질로 사용토록 함으로서 치수의 안정을 꾀하고 있으나 이럴 경우에는 강질은 밀폐력을 저하시킨다는 단점과 개폐시에 유연성이 덜어진다는 단점이 있는 것이다.Therefore, in order to solve such a problem of bending, it is usually intended to stabilize the dimensions by using a toma having a soft characteristic as a rigid, but in this case, the disadvantage of reducing the sealing force and the disadvantage of being less flexible during opening and closing. It is.

또한 이러한 테두리를 갖는 구조를 성형하기 위하여는 통상 슬라이드 금형에 의하여 제작되어짐으로 금형의 가격상승과 또한 사출시간의 지연과 슬라이드 작동되어질 경우에 발생되는 다양한 문제점 등으로 생산성이 떨어진다는 단점이 있는 것이다.In addition, in order to mold the structure having such a border is usually produced by the slide mold has a disadvantage in that the productivity is lowered due to the increase in the price of the mold and also the delay of the injection time and various problems that occur when the slide is operated.

따라서 본 고안은 이러한 문제점을 해소하기 위하여 뚜껑체의 외주연에 형성된 후렌지의 선단을 직하방으로 절곡토록 하여 수직살을 형성한 후 상기 수직살이 2중사출물에 내입되어지면서 성형토록 함으로서 성형의 용이성과 유연성은 물론 밀폐력을 만족토록 한 것이다.Therefore, in order to solve this problem, the present invention is to bend the tip of the flange formed on the outer periphery of the lid body to form a vertical bark after forming the vertical bark so that the vertical barb is embedded in the double injection molding to facilitate the molding and Flexibility is, of course, to satisfy the sealing force.

이하 첨부도면에 의거 본고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

우선 종래의 기술과 동일한 구성요소일 경우에도 서로 다른 참조부호를 갖도록 하였다.First, even the same components as in the prior art have different reference numerals.

도1은 본 고안의 기본적인 구조를 나타낸 것으로, 뚜껑체(10)의 외주연으로 형성된 후렌지(11)의 선단이 직하방으로 절곡되어져 수직살(12)이 형성되고 상기 수직살(12)이 내입되어지면서 2중사출에 의한 테두리(20)가 형성되는 것이다.Figure 1 shows the basic structure of the present invention, the front end of the flange 11 formed by the outer periphery of the lid body 10 is bent downwards to form a vertical flesh 12, the vertical flesh 12 is embedded It is to be formed by the edge 20 by the double injection.

이때 테두리(20)는 뚜껑체(10)의 후렌지(11)의 상부까지 연장되어지는 것이고, 상기 테두리(20)는 밀폐홈(21)이 형성되도록 외측과 내측으로 대향되도록 밀폐벽(22,23)을 형성하는 것이다.At this time, the edge 20 is extended to the upper portion of the flange 11 of the lid body 10, the edge 20 is sealed walls 22, 23 so as to face the outside and the inner side so that the sealing groove 21 is formed. ) To form.

이때 내측과 외측의 밀폐벽(22,23)의 서로 대응되는 벽으로는 모두 걸림수단(22a,23a)을 형성토록 함으로서 견고한 밀폐가 가능하게 되고 이러한 걸림수단(22a,23a)에 대응되도록 함체(30)의 상단변(31)에도 맞물림수단(32,33)을 형성토록 함으로서 밀폐력을 획보토록 함은 물론 개폐시에 독특한 소리의 발생으로 사용의 안정성을 갖도록 하는 것이다.At this time, both of the inner and outer sealing walls 22 and 23 correspond to each other so that the locking means 22a and 23a are formed so that a tight sealing is possible and the locking means 22a and 23a correspond to the enclosure ( By forming the engaging means (32, 33) in the upper side 31 of the 30) to ensure the sealing force as well as to ensure the stability of the use by the generation of a unique sound during opening and closing.

이러한 걸림수단과 맞물림수단은 대략적으로 만곡되어지도록 함으로서 개폐시 유연성을 확보토록 하면서 밀폐력을 우수하게 하고 개폐시의 잠금과 해제상태를 소리로 알 수 있도록 한 것이다.The locking means and the engaging means is to be approximately curved to ensure the flexibility during opening and closing while ensuring excellent sealing force and to know the lock and release state during opening and closing by sound.

또한 내측의 밀폐벽(23)에는 뚜껑체(10)의 수직살(12)이 내입되어지는 것이고, 이러한 수직살은 밀폐벽의 지지력을 확보토록 한 것이고이고 이러한 수직살은 밀폐벽보다는 짧게 형성토록 함이 유연성을 확보하게 되는 것이다.In addition, the vertical wall 12 of the lid body 10 is embedded in the inner sealing wall 23, and the vertical bark is to secure the supporting force of the closing wall, and the vertical bar is formed to be shorter than the closing wall. The ship will gain flexibility.

또한 이러한 내측의 밀폐벽(23)의 지지력을 확보하기 위하여 뚜껑체(10)의 수직살(12)의 전방으로는 수평살(13)을 형성하여 테두리의 지지력을 확보하게 되는 것이다.In addition, in order to secure the supporting force of the inner sealing wall 23, the horizontal bar 13 is formed in front of the vertical bar 12 of the lid 10 to secure the support force of the rim.

따라서 뚜껑이 함체와 결합될 경우에 뚜껑의 테두리가 연질로 되어 있고 뚜껑체의 수직살이 휨어짐을 지지하게 됨으로 종래와 같이 테두리의 내측으로 휨이 발생되지 않게 되는 것이고, 이러한 수직살이 2중사출성형시에 금형에서 지지력을 갖게 됨으로 2중사출시의 성형물의 흐름에 의한 형태의 변형이 발생되지 않게 되는 것이다.Therefore, when the lid is combined with the housing, the edge of the lid is soft and the vertical body of the lid supports the bending, so that the bending of the inside of the edge is not generated as in the prior art. Since the mold has a bearing force in the mold, deformation of the shape due to the flow of the molded product at the time of double injection does not occur.

또한 이러한 테두리의 대향되는 밀폐벽의 내측으로 걸림수단을 형성토록 하고 함체의 상단변에도 맞물림수단을 형성토록 함으로서 밀폐력을 우수하게 함은 물론 이러한 걸림수단과 맞물림수단에 의한 개폐시의 소리에 의하여 사용자에게 개폐되었음을 인지토록 하는 것이다.In addition, by forming the locking means to the inner side of the sealing wall facing the border and the engaging means on the upper side of the enclosure to improve the sealing force as well as the sound when opening and closing by the locking means and the engaging means. To be aware that it has been opened and closed.

따라서 연질의 토마를 이용하여 유연성과 밀폐력을 증대토록 할 수 있는 것이어서 성형의 용이성과 밀폐력은 물론 유연성을 동시에 만족시킬 수 있는 것이다.Therefore, it is possible to increase the flexibility and sealing force by using a soft toma to satisfy the ease of molding and sealing force as well as flexibility at the same time.
