Description

이중구조로 형성된 비닐밸브{A vinyl valve formed in double structure}A vinyl valve formed in double structure

본 발명은 2장의 얇은 비닐시트나 필름이 납작하게 눌려진 상태로 밀착되어 튜브나 비닐 팩 등의 주입구에 접착토록 됨으로서 기체나 액체를 주입시키기 위하여 사용되는 비닐밸브에 관한 것으로, 특히 내, 외부로 분리되어지는 이중구조로 형성되어 주입된 기체나 액체의 누수를 왁벽하게 방지토록 하기 위한 기밀성을 강화시킨 것이다.The present invention relates to a vinyl valve used to inject gas or liquid by adhering two thin vinyl sheets or films in a flat pressed state to be adhered to an inlet such as a tube or a plastic pack. It is formed in a dual structure to enhance the airtightness to prevent the leakage of the injected gas or liquid.

종래에 이러한 용도로 사용되는 비닐밸브(100)는 도 5에 도시된 바와 같이 2장의 얇은 비닐시트나 필름이 상, 하로의 통기구(101)(101a) 형성을 위하여 양측이 융착에 의하여 접착된 상태에서 가압에 의하여 밀착되어진 구조로서, 튜브(200) 등의 주입구(201)에 삽입되어진 상태에서 튜브(200) 등의 주입구(201)와의 접촉면으로 융착에 의한 접착부가 형성됨으로서 주입수단을 비닐밸브(100)의 통기구(101)(101a)에 삽입한 상태에서 기체나 액체의 주입이 가능하고 내용물이 주입된 후에는 외부로 유출되지 않토록 하는 것이었다.Conventionally, the vinyl valve 100 used for this purpose is a state in which two thin vinyl sheets or films are bonded to each other by fusion to form a vent hole 101 (101a) up and down as shown in FIG. As a structure that is in close contact by pressurization, the adhesive means is formed on the contact surface with the inlet 201, such as the tube 200 in the state of being inserted into the inlet 201, such as the tube 200, the injection means is a vinyl valve ( It was possible to inject gas or liquid in the state inserted into the vents 101 and 101a of 100, and to prevent it from flowing out after the contents were injected.

그러나 이러한 구조의 비닐밸브는 밀착 구조에 의해서도 비닐밸브의 통기구(101)(101a)를 완전히 차단시킬 수 없어 약간의 틈이 발생되고, 또한 비닐밸브가 접착되어진 튜브 등과의 접착부에 융착을 위하여 가해지는 열에 의한 늘어짐으로 얇아져서 약해짐은 물론 냉각 후 쭈그러지는 현상에 의하여 밸브가 접착되어진 튜브 등의 내부 압력 변화에 따른 터짐과 균열이 발생되어 주입된 내용물이 새게 되는 문제점이 있는 것이었다.However, the vinyl valve of such a structure is not able to completely block the vent valve 101 (101a) of the vinyl valve even by the close contact structure, so that a slight gap is generated, and the vinyl valve is applied for fusion to the bonding portion with the tube to which the vinyl valve is attached. The thinning and weakening due to the sagging of the heat as well as the crushing after cooling caused by the internal pressure change of the tube, such as the valve is adhered by the valve, there is a problem that the injected content leaks.

본 발명은 상기한 종래의 문제점을 해결하기 위하여 안출한 것으로서, 본 발명의 비닐밸브를 내, 외부로 구성되어지는 2개의 밸브체에 의한 이중 구조로 형성시켜 이중밀착구조에 의한 통기구의 이중차단효과 및 이중접착구조에 의한 기밀성을 강화토록 하고자 함이다.The present invention has been made in order to solve the above-mentioned conventional problems, the double-blocking effect of the vent by the double-closed structure by forming the vinyl valve of the present invention in a double structure by the two valve body is configured to the inside, the outside And to enhance the airtightness by the double adhesive structure.

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 과 도 2 에 도시된 바와 같이 본 발명의 비닐밸브는 2장의 얇은 비닐시트나 필름이 상, 하로의 통기구(11)(11a) 형성을 위하여 양측이 융착에 의하여 접착된 상태에서 가압에 의하여 밀착되어진 구조의 내부밸브(10)와, 상, 하로 통기구(21)(21a)가 형성토록 상기 내부밸브(10)와 동일한 밀착 구조로 이루어지면서 상기 내부밸브(10)가 내입된 상태에서 상측으로 융착에 의한 내부밸브(10)와의 접착부(22)가 형성되어진 외부밸브(20)로 구성되어 이중밀착구조에 의한 기밀성을 강화시킨 것이다.As shown in FIGS. 1 and 2, the vinyl valve of the present invention is formed by pressing in a state in which two thin vinyl sheets or films are bonded to each other by fusion for forming the vent holes 11 and 11a. The inner valve 10 has a close contact with the inner valve 10 such that the inner valve 10 and the upper and lower vents 21 and 21a are formed in close contact with each other, and the upper side of the inner valve 10 is upward. It is composed of an outer valve 20 in which the adhesive portion 22 is formed with the inner valve 10 by fusion, thereby enhancing the airtightness by the double close structure.

이때 상기 접착부(22)는 가열 가압에 의한 융착 또는 고주파 가열 등에 의한 융착 방식에 의하여 내입된 내부밸브(10)를 가로질러 접착토록 되는 것으로, 삽입된 내부밸브(10)의 통기구(11)(11a)가 막히지 않토록 내부밸브(10)의 내측으로는 이형제를 내삽토록 하거나 이형수단이 형성된 상태에서 융착토록 하여야 하는 것이다.At this time, the adhesive part 22 is to be bonded across the internal valve 10, which is embedded by the fusion method by the heating or pressurization or the fusion method by high-frequency heating, the vent holes (11) (11a) of the inserted inner valve 10 In order to prevent the c) from being blocked, the release agent should be inserted into the inner valve 10 or fused in a state where a release means is formed.

또한 상기 외부밸브(20)의 일면을 더 길게 형성하여 연장부(23)를 형성토록 함으로서 내부밸브(10)의 삽입이 용이하게 할 수 있는 것이고, 외부밸브(20)에 결합되어지는 내부밸브(10)를 외부밸브(20)의 상부로 노출시켜 결합토록 함으로서 기체나 액체 주입을 위하여 별도로 사용되는 대롱 등의 주입수단을 용이하게 삽입시킬 수 있도록 할 수 있는 것이다.In addition, by forming one side of the outer valve 20 longer to form an extension 23, the inner valve 10 can be easily inserted, and the inner valve coupled to the outer valve 20 ( By exposing 10 to the upper portion of the outer valve 20 to be coupled, it is possible to easily insert the injection means such as a separate ball for the gas or liquid injection.

또한 상기와 같이 이중구조로 이루어진 비닐밸브를 튜브(200) 등에 결합시킬 경우에는 외부밸브(20)에 내부밸브(10)를 먼저 내입시켜 융착에 의한 방식으로 접착시킨 상태에서 튜브(200) 등의 주입구(201)에 내부밸브(10)가 접착되어진 외부밸브(20)를 내입시켜 외부밸브(20)의 접착부(22)와 접해져 있는 튜브(200) 주입구(201)와의 접촉면을 융착에 의한 방식으로 접착토록 함으로서 비닐밸브의 접착부가 이중으로 융착토록 하여야 하는 것이다.In addition, in the case of coupling the vinyl valve having a double structure as described above, such as the tube 200, the inner valve 10 is first introduced into the outer valve 20, and the tube 200 is bonded in a fused manner. By injecting the outer valve 20 to which the inner valve 10 is attached to the inlet 201, the contact surface with the inlet 201 of the tube 200, which is in contact with the adhesive part 22 of the outer valve 20, is fused. By adhering to this, the adhesive part of the vinyl valve should be fused twice.

또한 상기 내부밸브(10)의 길이는 외부밸브(20)의 길이보다 짧게 형성시켜 외부밸브(20)에 내부밸브(10)가 내입되어진 상태에서 외부밸브(20)의 하단부를 내부밸브(10)의 하단부보다 길게 형성하여 어느 정도의 간격이 벌어지도록 하여 공간이 확보토록 되어야 이중밀착구조에 의한 내부밸브(10)의 통기구(11)(11a) 차단 효과를 최대한 증진시킬 수 있는 것이다.In addition, the length of the inner valve 10 is formed to be shorter than the length of the outer valve 20 to the lower end of the outer valve 20 in the state in which the inner valve 10 is in the outer valve 20, the inner valve 10 It is formed to be longer than the lower end of the gap so that a certain amount of space is to be secured to be able to maximize the blocking effect of the vent (11) (11a) of the inner valve 10 by the double close structure.

이러한 이유는 내부밸브(10)의 상단부에 형성되어지는 통기구(11)는 외부밸브(20)와 내부밸브(10)와의 1차 접착과정에서의 가압력과 튜브(200) 주입구(201)와의 2차 접착과정에서의 가압력에 의한 이중밀착으로 차단효과가 상승토록 되는 것이나, 내부밸브(10)의 하단부에 형성되어지는 통기구(11a)의 경우에는 약간의 틈이 발생되게 되기 때문에 외부밸브(20)의 하단부 외측으로 돌출될 경우에는 이중구조로 이루어진다고 볼 수 없고, 동일선상에 있을 경우에도 통기구(11a)에 발생되는 틈을 완전히 차단시킬 수 없기 때문이다.The reason for this is that the vent 11 formed at the upper end of the inner valve 10 has a secondary pressure between the pressurization pressure during the first bonding process between the outer valve 20 and the inner valve 10 and the inlet 201 of the tube 200. The blocking effect is increased by double close contact due to the pressing force in the bonding process, but in the case of the vent 11a formed at the lower end of the inner valve 10, a slight gap is generated. This is because, when protruding to the outside of the lower end, it cannot be regarded as having a double structure, and even when it is on the same line, the gap generated in the vent 11a cannot be completely blocked.

따라서 상기와 같이 구성되어진 본 발명의 비닐밸브는 밀착구조로 이루어진 외부밸브(20)와 내부밸브(10)에 의한 이중구조로 이루어져 외부밸브(20)의 하단부와 외부밸브(20)에 내입되어진 내부밸브(10)의 하단부 사이에 어느 정도의 간격이 벌어지도록 되어 공간이 확보됨으로서 비닐밸브가 접착되어진 튜브(200)에서 발생되어지는 내부압이 외부밸브(20)의 납작한 양 표면으로 작용되어 내부밸브(10)의 납작한 양 표면을 가압토록 하는 이중밀착구조로 이루어지도록 함으로서 내부밸브(10)의 하단부에 형성되는 통기구(11a)를 이중으로 차단시키는 효과를 얻을 수 있는 것이고, 또한 2 겹의 밸브체에 의한 접착부의 이중접착구조에 의하여 내부밸브(10)의 상단부에 형성되는 통기구(11)를 이중으로 차단시키는 효과를 얻을 수 있어 기밀성을 강화시킬 수 있는 것이다.Therefore, the vinyl valve of the present invention configured as described above has a double structure by the outer valve 20 and the inner valve 10 having a close contact structure, and the inside of the lower end of the outer valve 20 and the outer valve 20 are internally incorporated. The gap between the lower ends of the valves 10 is increased so that space is secured, so that the internal pressure generated from the tube 200 to which the vinyl valve is bonded is acted on both flat surfaces of the outer valve 20, thereby making the inner valve It is possible to obtain the effect of double blocking the air vent 11a formed at the lower end of the inner valve 10 by forming a double close contact structure to press both flat surfaces of (10). It is possible to obtain the effect of double blocking the vent 11 formed in the upper end of the inner valve 10 by the double adhesive structure of the adhesive portion by the adhesive portion to enhance the airtightness The.

본 발명의 비닐밸브는 내부밸브와 외부밸브에 의한 이중밀착구조에 의한 기밀성의 강화로 주입된 내용물이 새지 않게 되는 것이다.In the vinyl valve of the present invention, the injected contents are prevented from leaking by enhancing the airtightness by the double close contact structure by the inner valve and the outer valve.
