Description

잠금수단이 형성된 플라스틱 뚜껑을 갖는 금속 밀폐용기{A metal airtight container having a plastic lid with four locking devices}A metal airtight container having a plastic lid with four locking devices}

본 발명은 플라스틱 뚜껑으로 잠김토록 되는 금속 밀폐용기에 관한 것으로, 특히 뚜껑에 일체로 형성되는 잠금수단이 금속 본체에 형성된 결합돌부에 맞물리면서 잠김토록 한 것이다.The present invention relates to a metal hermetically sealed container to be locked with a plastic lid, in particular, the locking means formed integrally with the lid is to be locked while engaging the engaging protrusion formed on the metal body.

종래에 플라스틱 뚜껑에 일체로 잠금수단이 형성되어 본체와 결합에 의하여 잠김토록 하는 것으로는 도5에 도시된 바와 같이 봅체에는 결합돌부를 형성하고 뚜껑에는 결합홈이 형성된 잠금수단을 구비토록 함으로서 잠김이 가능토록 하였다.Conventionally, the locking means is integrally formed on the plastic lid to be locked by the coupling with the main body, as shown in FIG. 5, as shown in FIG. 5, the bobbin is formed by the coupling protrusion and the lid is provided with the locking means formed with the coupling groove. It was possible.

그러나 이러한 용기의 단점은 플라스틱 본체에 수납되어지는 내용물에 의하여 용기 본체가 변색되어지거나 또는 플라스틱 특유의 환경호르몬에 대한 부정적인 이미지로 인하여 인체에 무해한 플라스틱 재질을 사용한다고 하더라도 부정적인 면이 있었다.However, the disadvantage of such a container has a negative side even if the container body is discolored by the contents stored in the plastic body or if the plastic material that is harmless to the human body is used due to the negative image of the environmental hormone unique to the plastic.

또한 종래에도 스텐레스를 이용하여 잠금수단을 구비한 것이 있었으나 이러한 것의 단점은 내용물이 보이지 않는다는 점과 이러한 것을 제작할 경우에 별도의 용접수단이나 또는 결합수단이 필요하다는 것이다.In addition, in the prior art, there were ones provided with locking means using stainless steel. However, the disadvantages of this are that the contents are not visible and that a separate welding means or a coupling means is required when manufacturing the same.

따라서 이러한 스텐레스의 용기는 상당히 고가의 제품으로 시판되어짐으로 일반인들의 범용적인 사용이 불가능한 것이다.Therefore, these stainless steel containers are commercially available as a very expensive product is impossible for the general public.

따라서 최근에는 스텐레스 본체에 투명한 플라스틱 뚜껑이 결합토록 하는 용기가 시판되고 있으나 이러한 것은 뚜껑이 본체에 단지 가압에 의하여 끼워지는 것에 불과하여 잠금기능이 없다는 단점이 있는 것이다.Therefore, in recent years, a container for allowing a transparent plastic lid to be bonded to a stainless steel body is commercially available, but this is a disadvantage that the lid is merely inserted into the body by pressing and there is no locking function.

이러한 문제점은 스텐레스의 용기 본체에 잠금기능을 갖도록 하기 위하여는 스텐레스 본체가 스텐레스 평판을 프레스의 드로잉 공법으로 두드려서 용기로 구현토록 하기 때문에 용기 본체의 측면으로 돌출되는 결합돌부를 구현시키거나 또는 상측의 테두리에 결합돌부를 구현시키는 것이 불가능하기 때문이다.In order to have a locking function on the container body of the stainless steel, the stainless steel body implements the container by tapping the stainless flat plate by the drawing method of the press, thereby implementing the engaging protrusion protruding to the side of the container body or the upper edge. This is because it is impossible to implement a coupling protrusion in the.

따라서 본 발명의 스텐레스 테두리에 결합돌부가 형성되는 테두리단부재를 플라스틱으로 별도 성형하여 결합토록 함으로서 뚜껑의 결합홈이 형성된 잠금수단과 결합토록 한 것이다.Therefore, the edge end member in which the engaging protrusion is formed on the stainless steel rim of the present invention is molded by plastic so as to be combined with the locking means in which the coupling groove of the lid is formed.

이하에서는 첨부 도면을 참조하여 본 발명의 가장 바람직한 일 실시 예를 상세히 설명하기로 한다. 우선, 각 도면을 설명함에 있어 동일한 구성 요소들에 한해서는 비록 다른 도면상에 도시되더라도 동일한 참조부호를 사용토록 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in describing the drawings, the same reference numerals are used to refer to the same elements even though they are shown in different drawings.

도 1 내지 도 3에 도시된 바와 같이 본 발명은 투명한 플라스틱 뚜껑(10)에는 일체로 절첩되어지는 잠금날개(11)가 구비되고 잠금날개(11)에는 잠금수단(11a)이 구비되어지며 상기 뚜껑(10)과 결합되는 용기본체(20)는 스텐레스 평판을 프레스로 가공하여 상측 테두리단이 ∩자형으로 말려지게 되고 상기 ∩자형으로 말려진 부분에는 결착수단(31)이 강구된 테두리단부재(30)를 플라스틱으로 별도 성형하여 테두리단부재(30)의 밀착면(32)이 상기 용기체(20)의 테두리단의 ∩자형의 내측으로 끼워지면서 ∩자형의 하단이 말려지면서 테두리단 부재가 결합되어지는 구성이다.As shown in FIGS. 1 to 3, the present invention is provided with a locking wing 11 which is integrally folded on the transparent plastic lid 10, and a locking means 11a is provided on the locking wing 11. The container body 20 coupled to the 10 is processed by a stainless steel plate by pressing the upper edge end is curled in a U-shape, and the edge end member 30 in which the binding means 31 is formed in the U-shaped curled portion. ) Is molded separately from the plastic, and the contact surface 32 of the edge end member 30 is inserted into the U-shaped inner side of the edge of the container body 20 while the lower end of the U-shape is rolled and the edge end member is coupled. Losing composition.

이때 테두리단 부재(30)에 형성되는 결착수단(31)은 뚜껑(10)에 형성되는 잠금날개(11)의 잠금수단(11a)에 따라 일정간격이 유지되게 돌출되어지거나 일체로 연장되게 돌출되어지는 것이다.At this time, the binding means 31 formed on the edge end member 30 is protruded to maintain a predetermined interval or protrude integrally in accordance with the locking means (11a) of the locking blade (11) formed on the lid (10). To lose.

또한 결착수단(31)에는 하방으로 돌출되어지는 결착돌부(31a)를 형성하여 뚜껑(10)의 잠금날개(11)에 형성된 잠금수단(11a)에 걸려지게 함으로서 용이하게잠금상태가 해제되지 않게 한 것이다.In addition, the fastening means 31 is formed with a fastening protrusion 31a protruding downward so as to be caught by the locking means 11a formed on the locking blade 11 of the lid 10 so that the locking state is not easily released. will be.

또한 테두리단부재(30)의 밀착면(32)의 전방으로는 용기본체(20)의 ∩자형에 내입된 상태에서 ∩자형을 가압할 경우에 ∩자형의 선단이 말려지면서 테두리단부재(30)를 고정토록 하기 위하여 만곡돌부(33)를 형성하여 ∩자형에 내입되어 가압된 상태에서는 임의대로 테두리단부재(30)가 이탈되어지지 못하게 되는 것이다.In addition, the front end of the contact surface 32 of the rim end member 30 is pressed in the U-shape in the state of being embedded in the U-shape of the container body 20, the U-shaped end is curled while the rim end member 30 In order to fix the curved protrusion 33 is formed in the U-shaped indented state in the pressurized state the edge end member 30 will not be detached.

한편, 상기 뚜껑(10)의 테두리단에는 상기 용기체(20)의 테두리단 삽입을 위한 결합요입부(12)와 이 결합요입부(12)에 삽입 고정되어 밀착토록 하기 위한 패킹(13)이 형성되어짐은 물론이다.On the other hand, at the edge of the lid 10, the coupling inlet 12 for inserting the edge of the container body 20 and the packing 13 for inserting and fixed to the coupling inlet 12 is tight Of course it is formed.

따라서 상기와 같이 구성된 본 발명의 밀폐용기는 뚜껑(10)에 강구되어진 잠금수단(11a)이 용기본체의 테두리단부재에 장착되어진 결착수단(31)과 맞물리게 되면서 잠금기능을 하게 되는 것이고, 이러한 잠금기능은 스텐레스로 제작되어진 용기본체에 투명한 재질의 합성수지 뚜겅이 간단하여 결합토록 함으로서 간편한 조립은 물론 저렴한 가격의 제공이 가능하게 된 것이다.Therefore, the closed container of the present invention configured as described above is to be locked while the locking means (11a) is formed on the lid 10 is engaged with the binding means 31 mounted on the frame end member of the container body, such a lock The function is that the synthetic resin cover made of stainless steel is simply combined with the container body made of stainless steel, so that it is possible to provide simple assembly and low price.

상술한 바와 같이 본 발명의 밀폐용기는 용기와 뚜껑과의 고정을 위한 잠금장치가 형성되어 종래에 플라스틱 뚜껑과 금속재 용기로 이루어진 밀폐용기에서 발생되는 밀폐력 저하의 문제점을 해결할 수 있는 것이다.As described above, the closed container of the present invention is formed with a locking device for fixing the container and the lid to solve the problem of a decrease in the sealing force generated in the conventional closed container made of a plastic lid and a metal container.
