Description

액체용기 병마개 구조 및 금형장치{A structure of cap for the liquid bottle and its molding device}A structure of cap for the liquid bottle and its molding device

본 발명은 간장병, 식초병, 식용유병 등 주로 식음료병의 병마개를 구성함에 있어서, 파절기능에 의한 개봉편(開封片)의 성형을 위한 금형구조를 개선하여 금형의 제조방법을 보다 간편 용이하게 하고, 금형의 사용수명을 연장하며 제품 완성후 개봉편의 개봉작업이 손쉽게 이루어지도록 함을 목적으로 안출한 액체용기 병마개 구조 및 금형장치를 제공코자 하는 것이다.The present invention improves the mold structure for the molding of the open pieces by the fracture function in the configuration of the bottle cap of the food and beverage bottle mainly soy sauce bottle, vinegar bottle, edible oil bottle, etc. It aims to provide a liquid container bottle cap structure and mold apparatus for the purpose of extending the service life of the mold and making the opening work easier after the product is finished.

종래의 식음료병 마개에 적용된 개봉장치는 도 4에서 보는 바와 같이 개봉편(6)이 병마개의 본체와 같은 두께로서 동일한 평면을 유지한 상태로 구성하고 저면에 ∧형 할절홈(4b)을 형성하여 개봉편(6)을 손잡이(5) 고리로써 잡아당기면 상기 할절홈(4b) 부위가 강제로 찢어져서 개봉이 이루어지도록 구성한 것이다.The opening device applied to the conventional food and beverage bottle cap is configured in the state that the opening piece 6 is the same thickness as the main body of the bottle cap and maintains the same plane as shown in FIG. When the opening piece 6 is pulled out by the handle 5, the cutting groove 4b is forcibly torn so that the opening is made.

그러나 상기한 종래의 병마개 개봉장치는 개봉시 할절부가 잘 찢어지지 않아 힘이 많이 들고, 특히 금형 제작이 어려우며 금형의 장기 사용시 자체 마손현상이 발생하면 할절부의 두께가 상대적으로 두껍게 사출되므로 개봉시 파절이 용이하게 되지 않는 등 다수의 문제점이 있었던 것이다.However, the above-mentioned conventional bottle cap opening device has a lot of power due to the fact that the cutting part is not easily torn during opening, and in particular, it is difficult to manufacture the mold, and when the wear damage occurs during long-term use of the mold, the thickness of the cutting part is relatively thick, so that the fracture is easy during opening. There were a number of problems, such as not being done.

본 발명은 이상과 같은 종래의 병마개가 갖는 문제점에 착안하여 액체용기의 병마개 구조와 금형장치를 기존의 평면구조와는 달리 개봉편이 몸체보다 위로 융기된 입체적인 형태로 사출 성형되도록 형성하여 개봉편의 사출이 용이하고 금형의 제작 및 보수가 편리하며 개봉편의 개봉 시 힘이 적게 들도록 개량한 것이다.The present invention focuses on the problems of the conventional bottle cap as described above, unlike the conventional bottle cap structure and the bottle cap structure of the liquid container is formed so that the opening piece is injection molded in a three-dimensional form raised up than the body, the injection of the opening piece It is easy and easy to manufacture and repair mold, and it is improved to take less force when opening the piece.

본 발명에서 제공하는 병마개의 구성과 금형장치를 예시 도면에 의하여 상세히 설명한다.The configuration and mold apparatus of the bottle cap provided by the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 바람직한 실시예를 보인 병마개의 사시도이다.1 is a perspective view of a bottle cap showing a preferred embodiment of the present invention.

기존 병마개는 병마개 본체(1)에 겉뚜껑(2)이 일체로 연결되도록 사출성형하고 상부에는 호형의 안내벽(3)을 입설하여 그 내측 바닥부(4)에 도 4와 같이 할절홈(4b)을 형성하여 손잡이(5)를 잡아당기면 할절홈(4b) 내측에 형성되는 개봉편(6)이 찢어져서 내용물을 인출할 수 있도록 구성한 것이다.Existing bottle caps are injection molded so that the lid 2 is integrally connected to the bottle cap body 1, and a guide wall 3 of an arc shape is placed in the upper portion, and the cutout groove 4b as shown in FIG. 4 in the inner bottom portion 4 thereof. When the handle 5 is pulled out, the opening piece 6 formed inside the cutout groove 4b is torn so that the contents can be taken out.

본 발명은 상기 구성에 있어서 바닥부(4) 저면에 할절홈(4b)을 요설하지 않고 할절홈(4b)을 대신하여 개봉편(6)을 상기 바닥부(4)의 상부로 단이 지게 융기시켜 개봉편(6)의 주면과 바닥부(4)의 경계지점에 절개용의 얇은 할절부(6a)를 형성시킨 것이다.According to the present invention, the opening piece 6 is stepped up to the upper portion of the bottom portion 4 in place of the cutting groove 4b without concave cutting portion 4b at the bottom of the bottom portion 4. A thin cutout portion 6a for cutting is formed at the boundary point between the main surface of the unsealed piece 6 and the bottom portion 4.

상기 구성의 개봉편(6)과 할절부(6a) 형성을 위한 금형장치는 도 5에 표시한바와 같이 상금형(7)의 저면에 개봉편(6) 성형을 위한 요입부(7a)를 형성하고 하금형(8)에는 상기 개봉편(6) 저면을 형성하는 코어판(9)을 별개체로 형성하여 하금형(8)의 요입부(8a)에 코어판(9)을 결합하여 상기 상금형(7)의 요입부(7a)와 하금형(8)의 코어판(9)에 의해서 개봉편(6)이 바닥부(4) 위에 융기되어 사출성형하는 구성으로 된다.The mold apparatus for forming the opening piece 6 and the cutout portion 6a of the above configuration forms a recess 7a for forming the opening piece 6 on the bottom surface of the upper mold 7 as shown in FIG. 5. In the lower die 8, the core plate 9 forming the bottom surface of the opening piece 6 is formed as a separate body, and the core plate 9 is coupled to the recess 8a of the lower die 8 to the upper prize. The opening piece 6 is raised on the bottom part 4 by injection-molding by the recessed part 7a of the die 7 and the core plate 9 of the lower die 8.

이상과 같이 본 발명은 병마개의 성형을 위한 금형장치에 개봉편(6) 형성을 위한 상금형(7)의 요입부(7a)와 코어판(9)을 바닥부(4)의 높이보다 높게 설치하여 사출 후 개봉편(6)이 얇은 할절부(6a)에 의해 둘러싸이도록 형성한 것이므로, 병마개 완성 후 이를 개봉할 시에 손잡이(5)를 당겨주면 상기의 얇은 할절부(6a) 부분이 강제로 찢어지면서 개봉편(6)이 바닥부(4)로부터 분리되면서 개봉이 이루어지므로, 병마개의 개봉이 용이하고 개봉시 힘이 적게 들며 특히 금형의 제작이 용이하고 금형의 사용수명이 연장되는 이점이 있다.As described above, the present invention installs the recess 7a and the core plate 9 of the upper mold 7 for forming the opening piece 6 in the mold apparatus for forming the bottle cap higher than the height of the bottom 4. Since the opening piece 6 is formed so as to be surrounded by the thin cutout 6a after the injection, when the cap 5 is pulled out when the cap is opened, the thin cutout 6a is forced. Since the tearing is opened while the opening piece 6 is separated from the bottom portion 4, the opening of the bottle cap is easy, and the opening force is low, and in particular, the production of the mold is easy and the service life of the mold is extended.

상기와 같은 본 발명에서 제공하는 병마개의 구성 및 금형장치에 의한 효과를 보다 구체적으로 살펴보면 다음과 같다.Looking at the effect of the configuration of the bottle cap provided by the present invention as described above and the mold apparatus in more detail as follows.

① 개봉편(6)이 바닥부(4)로부터 단이지게 융기되어 주면의 얇은 할절부(6a)가 경계면을 이루고 있어 손잡이(5)를 위로 잡아 당기면 바닥부(4)와 같은 두께를 갖는 개봉편(6)이 일측으로부터 위로 들어 올려지면서 할절부(6a)가 용이하게 파절되므로 힘이 적게 들며, 개봉편(6)의 개봉이 손쉽게 이루어진다.① Opening piece 6 is raised from the bottom part 4 so that the thin cutout part 6a of the main surface forms an interface, and when the handle 5 is pulled up, the opening piece has the same thickness as the bottom part 4. As the 6 is lifted up from one side, the cutout portion 6a is easily fractured, so it takes less force, and the opening piece 6 is easily opened.

② 금형장치는 코어판(9)을 별개체로 결합하여 형성한 것이므로 코어판(9)의 두께를 가감조절하므로써 상기 할절부(6a)의 두께조절이 자재로와 사용 용도에 따라서 개봉의 강도(씰링강도)를 조절할 수 있다.(2) Since the mold apparatus is formed by combining the core plate 9 separately, the thickness control of the cutout portion 6a is performed by adjusting the thickness of the core plate 9 according to the material and the intended use. Sealing strength) can be adjusted.

③ 금형을 장기 사용하는 경우 상금형(7)의 요입부(7a) 또는 코어판(9)의 마손으로 할절부(6a)의 두께가 두꺼워지는 경향이 발생하지만, 본 발명은 코어판(9)의 높이를 조정하므로써 할절부(6a)의 두께 변화를 조절할 수 있어 금형의 사용수명을 연장할 수 있고 수리 및 보수가 용이하다.(3) When the mold is used for a long time, the thickness of the cutout portion 6a tends to become thick due to the wear of the recess 7a or the core plate 9 of the upper die 7, but the present invention is a core plate 9 By adjusting the height of the mold, the thickness change of the cutout portion 6a can be adjusted, thereby extending the service life of the mold and making it easy to repair and repair.

④ 금형 제조시 코어판(9)의 규격에 따라 할절부의 두께를 자유로이 설정할 수 있어 금형의 제조가 용이하고 금형비를 절감할 수 있다.④ The thickness of the cutout part can be set freely according to the standard of the core plate 9 during the mold manufacturing, so that the mold manufacturing is easy and the mold cost can be reduced.
