CONSTITUTION: An airtight container cap by dual-injection molding includes a main body having an integrally formed coupling part(10a) to be combined with a container(20), a coated layer(1) formed on the inner surface of the coupling part, and protrusion parts(2) protruded from the coated layer to the outside of the top part of the cap via many punched-out holes or opening parts for preventing the separation of the coating layer.

Description

2중 사출에 의한 밀폐용기 뚜껑{An airtight container cover which is made in double injection molding method}An airtight container cover which is made in double injection molding method}

본 발명은 플라스틱으로 제조되는 용기 뚜껑에 관한 것으로, 특히 밀폐력을 증대시키고, 밀폐를 위하여 사용되는 연질의 성형물이 경질의 성형물과 견고한 부착이 가능토록 하면서 성형 후에는 뚜껑의 평활도가 우수하게 하여 휨이 발생되지 않토록 한 것이다.The present invention relates to a container lid made of plastic, and in particular, to increase the sealing force, and to ensure that the soft molding used for sealing can be firmly attached to the hard molding, while the molding is excellent in the smoothness of the lid after bending It does not occur.

현재 밀폐를 위한 용기 뚜껑으로 사용되는 것으로는 도6에 도시된 바와 같이 2중 사출성형방식으로 뚜껑(10)의 몸체(11)를 먼저 성형한 후에 몸체(11)가 성형된 뚜껑의 외측테두리에 용기(20)와 결합되어지는 부분(10a)을 연질로 2중 사출성형토록 함으로서 결합되는 부분(10a)이 연질의 점성에 의하여 밀폐력을 향상토록 한 것이다.It is currently used as a container lid for sealing, as shown in Figure 6 is first molded the body 11 of the lid 10 by a double injection molding method, then the body 11 is formed on the outer edge of the lid The part 10a to be combined with the container 20 by soft injection molding is to improve the sealing force by the soft viscosity of the part 10a.

그러나 이러한 제품의 단점은 통상 사출성형되는 뚜껑의 몸체(11)가 1㎜정도의 두께로 성형되어지는 점을 감안하면 이러한 두께에 덧 씌우기 형식으로 2중사출성형할 경우에 덧씌워지는 부분의 두께가 0.1㎜정도인 점을 감안하면 덧씌워진 부분이 벗겨지게 되는 단점과 또한 2중 사출성형시에 뚜껑의 몸체(11)와의 성형조건의 차이로 냉각 시에 비틀림이 발생되어 뚜껑(10)의 평할도가 떨어지게 되는 단점이 있는 것이다.However, the drawback of such a product is that the thickness of the part which is overlaid in the case of double-injection molding in the form of overlaying on the thickness in consideration of the fact that the body 11 of the lid to be injection molded is molded to a thickness of about 1mm Is about 0.1 mm in that the overlaid part is peeled off and the twisting occurs during cooling due to the difference in molding conditions with the body 11 of the lid during double injection molding, the flatness of the lid 10 There is a disadvantage that falls.

따라서 이러한 비틀림을 방지하기 위하여 도7에 도시된 바와 같이 몸체(11)를 결합되어지는 부분(10a)이 포함되게 일체로 사출성형한 상태에서 결합되어지는 부분(10a)의 내측으로 연질을 코팅처리함으로서 코팅처리된 부분(13)의 점성으로 밀폐력을 향상시키고 있는 것이다.Therefore, in order to prevent such twisting, as shown in FIG. 7, the soft coating is applied to the inside of the portion 10a to be joined in the state of integrally injection molding to include the portion 10a to which the body 11 is coupled. By improving the sealing force by the viscosity of the coated portion (13).

그러나 내측으로만 코팅하기가 작업상 곤란함이 있고, 또한 코팅된 부분이 몸체(11)와 연결하는 수단이 없기 때문에 결국은 코팅된 부분이 떨어지게 된다는 단점이 있는 것이다.However, there is a disadvantage in that it is difficult to work only coating on the inside, and also because the coated part does not have a means for connecting with the body 11, and eventually the coated part falls off.

본 발명은 상기한 종래의 문제점을 해결하기 위하여 안출한 것으로서, 결합부분의 내측으로 2중사출에 의한 코팅층을 형성하면서 상기 코팅층은 뚜껑에 천공된 구멍 또는 개구부에 의하여 상부로 연장 돌출토록 하여 결합부분의 내측으로 형성된 코팅층이 탈리되지 않토록 하면서 코팅층에 의하여 밀폐력의 향상은 물론 외관을 우수하게 한 것이다.The present invention has been made in order to solve the above-mentioned conventional problems, while forming a coating layer by double injection into the inside of the coupling portion, the coating layer is extended to protrude upward by a hole or opening perforated in the lid portion While the coating layer formed to the inside of the coating layer is not to be detached to improve the sealing force as well as to improve the appearance.

이하에서는 첨부 도면을 참조하여 본 발명의 가장 바람직한 일 실시 예를 상세히 설명하기로 한다. 우선 종래의 구성과 동일한 부분에 대하여는 동일한 참조부호를 갖도록 하였다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, the same reference numerals are given to the same parts as the conventional configurations.

도1 내지 도4에 도시된 바와 같이, 뚜껑(10)이 용기(20)와 결합되는 부분(10a)을 뚜껑의 몸체(11)와 일체로 성형된 상태에서 결합되는 부분(10a)의 내측면으로 코팅층(1)을 형성하고, 상기 코팅층(1)은 그 상부로 천공된 구멍(3)을 통하여 뚜껑(10)의 상부로 돌출되면서 돌출부(2)를 형성하여 코팅층(1)이 임의대로 탈리되지 않토록 된 구성이다.1 to 4, the inner surface of the portion 10a to which the lid 10 is coupled to the container 20 in a state in which the lid 10a is integrally molded with the body 11 of the lid. To form a coating layer (1), the coating layer (1) protrudes to the upper portion of the lid 10 through a hole (3) perforated thereon to form a protrusion (2) to the coating layer (1) detached arbitrarily This is not a configuration.

이때 구멍(3)의 크기와 위치는 제품의 외관의 형태에 따라 약간씩의 차이를 갖게 되는 것이고, 이러한 구멍(3)의 대용으로 개구부(4)를 형성하여 사용할 수 있는 것이다.At this time, the size and position of the hole (3) will have a slight difference depending on the appearance of the product, it can be used to form the opening (4) in place of the hole (3).

또한 뚜껑(10)의 상부로 돌출되어진 돌출부(2)의 표면에는 제품의 상표나 마크등을 성형시에 일체로 형성할 수 있는 것이고, 이러한 마크나 상표등은 2중사출성형시에 사용되는 금형에만 각인토록 함으로서 저렴한 가격으로 다양한 제품의 생산이 가능하게 되는 것이다.In addition, the surface of the protruding portion 2 protruding to the upper portion of the lid 10 can be integrally formed with a trademark or mark of the product at the time of molding, such a mark or trademark is a mold used in the double injection molding Only by imprinting will be able to produce a variety of products at a low price.

또한 이러한 돌출부(2)를 뚜껑(10)의 외곽라인을 따라 일체로 형성하거나 일정간격을 유지하여 형성할 경우에는 다양한 디자인의 제품 생산이 가능하게 되는 것이다.In addition, when the protrusion 2 is integrally formed along the outer line of the lid 10 or formed by maintaining a predetermined interval, it is possible to produce products of various designs.

또한 뚜껑(10)이 용기(20)와 결합되어지는 부분(10a)을 2중 사출성형에 의하여 성형토록 하고, 돌출부(2)를 결합되어지는 부분(10a)의 내벽(12)에 천공된 구멍(12a)과 뚜껑의 상부에 천공된 구멍(3)을 통하여 일체로 사출성형토록 할 경우에도 밀폐력의 향상을 갖도록 하면서 뚜껑자체의 휨이 발생되는 것을 방지할 수 있는 것이다.In addition, the lid 10 is formed by double injection molding the portion 10a to be combined with the container 20, and the projections 2 are drilled in the inner wall 12 of the portion 10a to be joined. In the case of integrally injection molding through 12a and the perforated hole 3 in the upper part of the lid, it is possible to prevent bending of the lid itself while improving the sealing force.

따라서 코팅층(1)이 용기와 결합되는 부분(10a)이 일체로 사출성형된 상태에서 연질로 2중 사출성형됨으로서 용기 뚜껑의 휨이 발생되는 것을 방지하게 되고, 또한 성형된 코팅층이 뚜껑의 몸체에 형성된 구멍등을 통하여 뚜껑몸체와 일체로 사출성형되기 때문에 코팅층이 견고하게 고정되어지는 것이고, 이러한 코팅층이 뚜껑의 구멍을 통하여 상부로 노출되면서 돌출부를 형성하기 때문에 상기 돌출부에 상표등을 표기토록 함으로서 제품의 디자인을 우수하게 할 수 있는 것이다.Accordingly, the double layer injection molding is performed in a state in which the portion 10a to which the coating layer 1 is coupled to the container is integrally injection molded, thereby preventing warpage of the container lid, and the molded coating layer is formed on the body of the lid. Since the injection molding is integrally formed with the lid body through the formed holes, the coating layer is firmly fixed, and since the coating layer is formed through the opening of the lid to expose the protrusions, the product can be marked on the protrusions. I can make the design superior.

상술한 바와 같이 본 발명은 뚜껑의 용기와 결합되는 부분에 코팅층을 형성함으로서 뚜껑의 휨을 방지하게 되고, 코팅층이 뚜껑의 상부로 돌출되어짐으로 코팅층의 탈리를 방지하게 되고 동시에 디자인이 우수한 제품을 제공할 수 있는 것이다.As described above, the present invention prevents the cover from bending by forming a coating layer on a portion coupled to the container of the lid, and prevents the coating layer from being detached by protruding the coating layer to the top of the lid, and at the same time, provide a product having an excellent design. It can be.
