Description
본 고안은 병마개에 관한 것으로, 더욱 상세하게는 병마개가 일체형으로 되어 병마개 제조시 작업공정이 단순해지고, 병마개의 바닥부에 형성된 돌기들에 의해 잠겨진 상태에서 기밀성이 우수해지는 플라스틱 병마개에 관한 것이다.The present invention relates to a bottle cap, and more particularly, to a plastic bottle cap which is excellent in the airtightness in the locked state by the projections formed on the bottom of the bottle cap is simplified by the integrated process of the bottle cap is integrated.
주지된 바와 같이, 병마개는 병과 같은 용기에 충진된 내용물이 외부로 유출되는 것을 방지하도록 하는 물품인데, 종래에는 도 4에 도시된 것과 같이, 병마개(100)는 내측면에 병목의 상단 외주부에 형성된 나사산과 일치하는 나산산을 갖추고 있고, 바닥면에 바닥면의 원주와 거의 같은 크기의 라이너(110)가 위치되어 있다. 따라서, 병마개(100)가 병목(200)의 나사산을 타고서 아래로 전진하면서 병목(200)의 병구(201)가 라이너(110)를 강하게 밀착하면서 고정된다. 이에 병에 충진된 내용물이 외부로 유출되지 않는다. 여기서 상기 병마개(100)은 일반적으로 알루미늄과 같은 재질로 제작되나, 최근에는 플라스틱과 같은 재질로도 제작되고 있다.As is well known, the bottle cap is an article which prevents the contents filled in a container such as a bottle from leaking to the outside, and as shown in FIG. 4, the bottle cap 100 is formed on the inner side of the upper outer circumference of the bottleneck. Liner 110 is provided with a thread that coincides with the thread and is approximately the same size as the circumference of the bottom. Therefore, the bottle cap 100 is fixed while the bottleneck 201 of the bottleneck 200 is in close contact with the liner 110 while the bottle cap 100 moves forward by riding the thread of the bottleneck 200. The contents filled in the bottle does not leak to the outside. Here, the bottle cap 100 is generally made of a material such as aluminum, but recently, it is also made of a material such as plastic.
도 5에 도시된 또 다른 병마개(200)는 내측면에 병목의 상단 외주부에 형성된 나사산과 일치하는 나산산을 갖추고 있고, 바닥면에 병목의 상단을 밀착고정할 수 있는 리브(102)가 일체형으로 형성되어 있다. 따라서, 병마개(101)가 병목(200)의 나사산을 타고서 아래로 전진하면서 병목(200)의 병구(201)가 리브(102)와 면접하면서 강하게 밀착고정된다. 이에 병에 충진된 내용물이 외부로 유출되지 않는다. 한편 상기 병마개(101)는 일반적으로 플라스틱과 같은 재질로 제작되고 있다.Another bottle cap 200 shown in Figure 5 has a thread on the inner side of the bottle thread corresponding to the thread formed on the outer periphery of the top of the bottleneck, the bottom 102 is integrally ribs 102 that can securely close the top of the bottleneck Formed. Accordingly, the bottle cap 101 is advanced downward while riding on the thread of the bottleneck 200, and the bottleneck 201 of the bottleneck 200 is firmly fixed while interviewing the rib 102. The contents filled in the bottle does not leak to the outside. On the other hand, the bottle cap 101 is generally made of a material such as plastic.
여기서 상기 병마개(100)는 별도의 라이너(110)가 필요하게 되고, 이것에 의해 병마개(100) 속으로 라이너(110)를 끼워넣는 추가적인 작업을 해야만 되어 작업시간이 많아져 비용이 증가되는 문제점이 발생하게 된다.Here, the bottle cap 100 requires a separate liner 110, and thus, the additional work of inserting the liner 110 into the bottle cap 100 requires additional work, thereby increasing the work time and increasing the cost. Will occur.
한편 용기속의 내용물이 오래 보존하고자 용기를 살균할 때에는 상기 또 다른 병마개(101)의 리브(102)가 팽창하였다가 수축됨으로 인해 병구(201)와 병마개(101) 사이에 미세한 틈이 발생하게 되어 기밀 유지가 힘들게 되는 문제점이 발생하게 된다.Meanwhile, when sterilizing the container in order to preserve the contents in the container for a long time, a fine gap is generated between the bottle cap 201 and the bottle cap 101 due to the expansion and contraction of the rib 102 of the another bottle cap 101. Problems occur that are difficult to maintain.
이에 본 고안은 상기와 같은 제반 문제점들을 해소하기 위해 안출된 것으로, 병마개가 일체형으로 되어 병마개 제조시 작업공정이 단순해지고, 병마개의 바닥부에 형성된 돌기들에 의해 잠겨진 상태에서 기밀성이 우수해짐은 물론 높은 온도에서도 별다른 변형이 발생되지 않게 되는 플라스틱 병마개를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and the bottle cap is integrated to simplify the work process when manufacturing the bottle cap, and the airtightness is excellent in the locked state by the protrusions formed at the bottom of the bottle cap. Its purpose is to provide a plastic bottle cap that will not cause any deformation even at high temperatures.

이하, 본 고안을 첨부한 도면을 참조로 하여 상세하게 설명하기로 한다.Hereinafter, with reference to the accompanying drawings of the present invention will be described in detail.
도 1은 본 고안에 따른 병마개의 단면도이고, 도 2는 일반적으로 사용되는 병의 병목을 단면으로 나타낸 도면이며, 도 3은 본 고안에 따른 병마개에 병목이 잠겨진 상태의 단면도이다.1 is a cross-sectional view of the bottle cap according to the present invention, Figure 2 is a view showing a bottleneck of the bottle generally used, Figure 3 is a cross-sectional view of the bottle cap is locked to the bottle cap according to the present invention.
도시된 바와 같이, 본 고안은 바닥부(3)에는 제1돌기(3-2)와 제2돌기(3-3)가 형성되어 있고 돌기 안쪽에는 단부가 꾸부러진 밀착부(3-1)가 형성되어 있고, 측면부(4)에는 다수개의 나사산(4-1)이 형성되어 있고 이 측면부(4)의 단부에는 삼각형 단면의 돌기단(4-2)이 원주 전체에 걸쳐 형성되어 있다. 그리고, 상기 구성요소들은 일체로 성형된다.As shown in the present invention, the bottom portion 3 has a first protrusion 3-2 and a second protrusion 3-3 formed therein, and the inside of the protrusion has an adhesive part 3-1 having an end portion thereof. A plurality of threads 4-1 are formed in the side surface portion 4, and a projection end 4-2 having a triangular cross section is formed over the entire circumference at an end portion of the side surface portion 4. The components are then molded integrally.
이렇게 형성된 본 고안의 병마개(1)가 병목(10)에 결합되는 과정을 상세하게 설명하기로 한다.The bottle cap 1 of the present invention formed as described above will be described in detail in the process coupled to the bottleneck 10.
먼저, 병목(10)의 상단인 병구(13)에다 병마개(1)를 예비로 얹은 다음 우측방향(시계방향)으로 돌리게 되면, 병마개(1)의 나사산(4-1)이 병목(10)의 나사산(11)을 타고서 아래방향으로 전진하게 되면서 병구(13)가 병마개(1)의 밀착부(3-1)에 닿게 된다. 이때 최초의 회전력보다 강하게 병마개(1)를 우측방향으로 계속 돌리게 되면, 병목(10)의 병구(13)가 밀착부(3-1)와 밀착되면서 전진하게 되고 이어 제1돌기(3-2) 및 제2돌기(3-3)와 강하게 밀착된다. 이때, 병목(10)의 최종 나사산(12)이 측면부(4)의 단부에 형성된 돌기단(4-2)을 넘어 이 돌기단(4-2)에 걸리게 되어 병목(10)에 병마개(1)가 견고하게 고정되게 된다.First, when the bottle cap 1 is preliminarily put on the bottle cap 13, which is the upper end of the bottleneck 10, and then turned to the right (clockwise), the thread 4-1 of the bottle cap 1 is The bottleneck 13 is in contact with the contact portion 3-1 of the bottle cap 1 while being advanced downward by taking the thread 11. At this time, if the bottle cap 1 is continuously turned to the right direction more strongly than the initial rotational force, the bottleneck 13 of the bottleneck 10 is advanced while being in close contact with the close contact portion 3-1 and then the first protrusion 3-2. And it is in close contact with the 2nd protrusion 3-3. At this time, the final thread 12 of the bottleneck 10 is caught by the protrusion end 4-2 beyond the protrusion end 4-2 formed at the end of the side portion 4, and the bottle cap 1 on the bottleneck 10. Is firmly fixed.
따라서 상기와 같이 견고하게 고정되는 병마개(1)는 내용물의 살균을 위해 높은 온도의 열(약 90℃ 이상)을 가해도 강하게 밀착되는 밀착부(3-1) 및 제1,2돌기(3-2,3-3)에 의해 내용물의 누수가 발생하지 않게 된다. 이는 밀착부(3-1)가 열을 받아서 팽창했다가 수축을 하더라도 도 3에 도시된 것처럼 밀착부(3-1)가 탄성력을 갖고서 결합되어 있어서 팽창 및 수축으로 발생되는 변형을 충분히 극복할 수가 있기 때문이다.Therefore, the bottle cap 1, which is firmly fixed as described above, has a close contact portion 3-1 and the first and second protrusions 3-1 that are tightly adhered even when high temperature heat (about 90 ° C. or more) is applied to sterilize the contents. 2,3-3) prevents leakage of the contents. Even if the close contact portion 3-1 expands and contracts under heat, as shown in FIG. Because there is.
상기 병마개(1)는 바람직하기로 플라스틱 내지 다양한 합성수지로 제작되게 된다.The bottle cap 1 is preferably made of plastic or various synthetic resins.
여기서 병목(10)에서 병마개(1)를 제거할 때에는 상기 돌기단(4-2)이 파손될 수 있는 정도의 힘으로 병마개(1)를 좌측방향(반시계방향)으로 강하게 돌리게 되면, 상기 병목(10)의 최종 나사산(12)이 돌기단(4-2)을 파손하면서 병목(10) 및 병마개(1)의 나사산(4-1, 11)에 의해 회전하게 되어 병목(10)에서 병마개(1)가 제거된다.When the bottle cap 1 is removed from the bottleneck 10, if the bottle cap 1 is strongly turned to the left (counterclockwise) with the force that the protrusion end 4-2 may be damaged, the bottleneck ( The final screw thread 12 of the 10 is rotated by the screw threads 4-1 and 11 of the bottle cap 10 and the bottle cap 1 while the protrusion end 4-2 is broken. ) Is removed.
이렇게 제거된 병마개(1)는 측면부(4)의 돌기단(4-2)의 파손으로 인해 다시 견고하게 병목(10)에 결합될 수 없게 된다. 즉, 한번 사용된 병마개(1)는 다시 병목(10)에 고정할 수 없게 된다. 따라서, 종래에 사용되던 안전띠(봉인)를 사용하지 않아도 용기의 사용된 유무를 간단하게 확인할 수 있게 된다.The bottle cap 1 thus removed cannot be firmly coupled to the bottleneck 10 due to the breakage of the protruding end 4-2 of the side part 4. That is, once used bottle cap 1 can not be fixed to the bottleneck 10 again. Therefore, it is possible to easily check the presence or absence of the container without using the safety belt (seal) used in the related art.
이상과 같이 자세하게 설명한 본 고안에 의하면, 병마개가 일체형으로 되어 병마개 제조시 작업공정이 단순해지고, 병마개의 바닥부에 형성된 돌기들에 의해 잠겨진 상태에서 기밀성이 우수해짐과 더불어 높은 온도에서도 별다른 변형이 발생되지 않게 됨에 따라, 탄산가스를 함유하는 음료수 및 드링크제용으로 사용할 수가 있다. 또한 안전띠(봉인)를 사용하지 않아도 용기의 사용된 유무를 간단하게 확인할 수 있는 효과가 있다.According to the present invention described in detail as described above, the bottle cap is integrated to simplify the work process at the time of manufacturing the bottle cap, excellent sealing property in the locked state by the protrusions formed on the bottom of the bottle cap, and also a different deformation occurs at high temperature. As a result, it can be used for beverages and carbonated drinks containing carbon dioxide gas. In addition, there is an effect that can be easily checked whether the container is used even without using a seat belt (sealing).
