이하, 본 발명을 첨부한 도면을 참조로 하여 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 알루미늄 병마개의 조립되기전의 사시도이고, 도 2는 본 발명에 따른 알루미늄 병마개의 조립된 상태의 사시도이며, 도 3은 본 발명에 따른 알루미늄 병마개의 조립된 상태의 단면도이다.1 is a perspective view before assembly of the aluminum bottle cap according to the present invention, Figure 2 is a perspective view of the assembled state of the aluminum bottle cap according to the present invention, Figure 3 is a cross-sectional view of the assembled state of the aluminum bottle cap according to the present invention.

도시된 바와 같이, 본 발명은 알루미늄 박판으로 형성되어지는 대략 '캡'형상의 외부캡(10)과, 내주연에 나사산이 형성되어 있으며 외주면 상단 아래에 돌기(21)가 외주면을 따라 일정하게 형성되어 있으며 상기 외부캡(10) 속으로 삽입되어지는 병마개바디(20)로 이루어진다.As shown, the present invention has a substantially 'cap' shaped outer cap 10 is formed of a thin aluminum plate, the thread is formed on the inner circumference and the projection 21 is formed uniformly along the outer circumferential surface below the upper peripheral surface It is made of a bottle cap body 20 is inserted into the outer cap 10.

여기서 상기 외부캡(10)의 내경은 병마개바디(20)의 상단부 외경보다 0.5 ∼ 1㎜ 보다 크게 제작되어지고, 외부캡(10)의 깊이는 병마개바디(20)의 상단부에 형성된 돌기(21)를 충분히 덮을 수 있을 정도로 설정되어 제작되어진다.Here, the inner diameter of the outer cap 10 is made larger than 0.5 ~ 1mm than the outer diameter of the upper end of the bottle cap body 20, the depth of the outer cap 10 is a projection 21 formed on the upper end of the bottle cap body 20 It is set so as to cover enough.

한편 상기 돌기(21)는 외부캡(10)이 덮어져 압착된 후, 이 외부캡(10)이 돌기(21)에 의해 좌우로 유격되지 않을 정도의 크기로 제작된다. 이는 외부캡(10)을 이루고 있는 알루미늄 박판의 두께와 연관되어 있으나, 박판의 두께를 고려하지 않아도 될 정도로 제작되어야만 된다.On the other hand, after the protrusion 21 is covered by the outer cap 10 is compressed, the outer cap 10 is manufactured to a size such that the protrusion 21 is not spaced from side to side. This is related to the thickness of the aluminum sheet forming the outer cap 10, but should be manufactured to a degree that does not have to consider the thickness of the sheet.

상기와 같은 본 발명의 병마개의 제작방법을 이하에서 상세하게 설명하기로 한다.The manufacturing method of the cap according to the present invention as described above will be described in detail below.

먼저, 알루미늄 박판을 금형을 이용해 캡의 형상을 만든후, 이 외부캡(10)의 상단면에 여러가지 문양 내지 표장을 찍어 넣는다.First, after forming a shape of the cap by using a thin aluminum sheet metal mold, various patterns or marks are imprinted on the upper surface of the outer cap (10).

이어 병마개바디(20)를 사출과 같은 성형방법으로 제작한다. 이때 병마개바디(20)의 상단 외주면 아래에 돌기(21)가 형성되도록 미리 설정한다.Then, the bottle cap body 20 is manufactured by a molding method such as injection. At this time, the projection 21 is set in advance so that the protrusion 21 is formed below the upper outer circumferential surface of the bottle cap body 20.

다음으로 상기 외부캡(10)을 병마개바디(20)의 상단에 끼운후, 외부캡(10)의 상단과 병마개바디(20)를 고정수단으로 고정시킨 다음, 압착수단에 의해 병마개바디(20)의 돌기(21)를 덮고 있는 외부캡(10)부를 압착하여 누르면서 회전됨에 의해, 병마개바디(20)의 돌기(21) 형상이 외부캡(10)에 찍히면서 병마개바디(20)에 외부캡(10)이 견고하게 고정된다.Next, after inserting the outer cap 10 to the top of the bottle cap body 20, the top of the outer cap 10 and the bottle cap body 20 is fixed by the fixing means, the bottle cap body 20 by the pressing means By rotating while pressing and pressing the outer cap (10) covering the protrusion 21 of the cap 20 of the bottle cap 20 is taken on the outer cap 10, the outer cap (20) 10) is firmly fixed.

따라서 상기 병마개바디(20)에 외부캡(10)이 고정되어 결합되되, 이 외부캡(10)을 잡고서 회전하여도 이 외부캡(10)이 병마개바디(20)에서 이격되지 않게 된다. 물론 외부캡(10)의 재질이 알루미늄임에 따라 여러가지 문양을 각인할 수 있고, 여러 가지 문양을 인쇄할 수 있게 된다.Therefore, the outer cap 10 is fixedly coupled to the bottle cap body 20, and the outer cap 10 is not spaced apart from the bottle cap body 20 even when the cap is rotated while holding the outer cap 10. Of course, as the material of the outer cap 10 is aluminum, various patterns can be imprinted, and various patterns can be printed.

이상과 같이 상세하게 설명된 본 발명에 의하면, 병마개바디에 돌기를 형성하고, 이 돌기를 덮고 있는 외부캡을 강하게 압착하여 고정함에 따라, 종래에 필수적으로 사용되어 왔던 접착제 내지는 열가소성수지의 사용을 폐지할 수 있어 원가를 줄일 수 있음은 물론, 비교적 까다로운 공정인 접착 공정을 삭제할 수 있어 작업의 효율성이 향상되는 효과가 있다.According to the present invention described in detail as described above, by forming a protrusion on the bottle cap body, and by strongly pressing and fixing the outer cap covering the protrusion, the use of adhesives or thermoplastic resins that have been used in the past is abolished. In addition, the cost can be reduced, and the adhesive process, which is a relatively difficult process, can be deleted, thereby improving work efficiency.

또한 상기 외부캡이 병마개바디에 접착되는 방식에서 발생되던 외부캡의 거칠은 마무리가 본 발명에서는 이 부분이 말아 올려져 병마개바디의 안쪽으로 숨겨짐에 따라 외관 마무리가 깔끔해지는 효과가 있다.In addition, the rough finish of the outer cap generated in the manner in which the outer cap is bonded to the bottle cap body in the present invention has the effect that the exterior finish is neat as this part is rolled up and hidden inside the bottle cap body.
