Description

원터치 타입 자기팽창 튜브{One touch type self-inflatable tube}One touch type self-inflatable tube

본 발명은 원터치 타입 자기팽창 튜브에 관한 것으로서, 보다 구체적으로는 내부에 기체가 없는 상태로 간편하게 운반 및 휴대하다가 필요시 손으로 튜브내에 내장된 용액 봉지(B)를 눌러주거나 타격해 터트려 주면 자기팽창이 일어나 바로 사용이 가능한 원터치 타입 자기팽창 튜브에 관한 것이다.The present invention relates to a one-touch type self-expansion tube, and more specifically, to easily carry and carry with no gas inside, and if necessary, by pressing or hitting the solution bag (B) embedded in the tube by hand, the self-expansion The present invention relates to a one-touch type self-expansion tube that can be used immediately.

본 발명에 있어서는 튜브라는 용어를 응원용 도구 등으로 사용되는 막대풍선, 어린이 장남감으로 사용되는 칼 모양등의 풍선, 수영튜브 등과 같은 물놀이용 기구, 에어방석, 구명조끼용 튜브 등을 총칭하는 용어로 사용하였다.In the present invention, the term "tube" is used to refer to a balloon, such as a bar balloon used as a tool for cheering, a balloon shaped like a knife used for children's toys, a swimming tube such as a swimming tube, an air cushion, a life jacket, etc. Used.

종래의 막대풍선 등의 튜브는 도 3에 도시된 바와 같이 일측에 공기주입용 체크밸브(D2)가 개구부(D1) 내에 설치된 후 상기 개구부(D1)를 열융착 처리하여 형성된 공기주입부(D)가 구비되어 있고, 사용시에는 상기 공기주입용 체크밸브(D2)를 통해 외부에서 기체를 튜브본체(A) 내로 주입하는 작업이 필요하였다.As shown in FIG. 3, a conventional air balloon (D) is formed by heat-sealing the opening part D1 after an air injection check valve D2 is installed in the opening part D1 on one side thereof, as shown in FIG. 3. Is provided, and in use it was necessary to inject gas into the tube body (A) from the outside through the air injection check valve (D2).

도 3은 종래 막대풍선(튜브)의 단면도이다.3 is a cross-sectional view of a conventional bar balloon (tube).

상기와 같이 종래의 막대풍선(튜브)는 사용을 위해서는 튜브본체(A) 내에 기체를 주입하는 별도의 작업이 필요하여 번거롭고, 기체주입장치가 없는 장소에서 사용하기 위해서는 미리 기체를 주입하여 운반해야 하는 경우가 많아 운반 및 휴대가 불편하고, 사람의 입으로 튜브본체(A) 내에 기체를 주입하는 경우에는 속도가 느리고 많은 노력이 소모되는 문제 등이 있었다.As described above, the conventional bar balloon (tube) requires a separate operation for injecting gas into the tube body (A) for use, and has to be injected and transported in advance for use in a place without a gas injection device. In many cases, it is inconvenient to transport and carry, and when gas is injected into the tube body A into the mouth of a person, there is a problem that the speed is slow and a lot of effort is consumed.

또 다른 종래기술로서, 대한민국 공개특허 제2006-0134407호에서는 앞에서 설명한 여러 문제점들을 해결하기 위해서 도 4에 도시된 바와 같이 일측에 (ⅰ) 염산에 구연산이 용해된 용액이 밀봉된 작은 봉지(1), (ⅱ) 상기 작은 봉지(1)와 탄산수소나트륨 분말이 각각 담겨진 큰 봉지(2) 및 (ⅲ) 필요시 상기 작은 봉지(1)에 구멍을 뚫어주는 돌출핀(3)을 포함하는 기체발생장치(E)가 설치되어 외부에서 기체를 주입하지 않고도 사용시 상기의 작은 봉지(1)를 돌출핀(3)으로 찔러줌으로써 구연산과 탄산수소나트륨의 반응에 의해 기체가 막대풍선 내부에서 자체적으로 발생하여 자기팽창하는 막대풍선을 게재하고 있다.As another conventional technology, Korean Patent Application Publication No. 2006-0134407 discloses a small bag (1) in which a solution in which citric acid is dissolved in hydrochloric acid is sealed on one side as shown in FIG. (Ii) a gas generating comprising a small bag (1) and a large bag (2) each containing sodium bicarbonate powder and (iii) a protruding pin (3) for drilling holes in the small bag (1), if necessary When the device (E) is installed and used without injecting gas from the outside, the small bag (1) is used to stick the protruding pin (3) so that the gas is generated by the reaction of citric acid and sodium bicarbonate by itself. A self-expanding bar balloon is shown.

도 4는 대한민국 공개특허 제2006-0134407호에 게재된 막대풍선의 단면도이다.4 is a cross-sectional view of a bar balloon published in Korean Patent Laid-Open Publication No. 2006-0134407.

도 4에 도시된 종래의 막대풍선은 작은 봉지(1)를 돌출핀(3)으로 찔러 천공함으로써 작은 봉지(1) 내에 담기 용액, 다시말해 염산에 구연산에 녹아 있는 용액이 큰 봉지(2) 내에서 탄산수소나트륨 분말과 접촉하게 되고, 이로 인해 구연산과 탄산수소나트륨이 반응하여 탄산가스를 생성하여 큰 봉지(2)를 팽창시킨 후 파열시키고, 상기 탄산가스는 막대풍선 내부 전체로 확산되어 결국 막대풍선이 외부에서 기체를 주입하지 않아도 자체적으로 부풀어 오르게 된다.In the conventional bar balloon shown in FIG. 4, the small bag 1 is punctured by the protruding pins 3 and perforated, so that the solution contained in the small bag 1, that is, the solution dissolved in citric acid in hydrochloric acid is large in the bag 2. In contact with the sodium bicarbonate powder, which causes citric acid and sodium bicarbonate to react to produce carbonic acid gas, which expands and ruptures the large bag (2). The balloon will inflate itself without injecting gas from the outside.

이때, 작은 봉지(1) 내에 담긴 염산은 일종의 촉매제 역할을 한다.At this time, the hydrochloric acid contained in the small bag 1 serves as a kind of catalyst.

만약 탄산수소나트륨 분말과 구연산 분말을 그대로 반응시키면 탄산가스 발생속도가 너무 늦어 풍선이 모두 팽창되는데 너무 많은 시간이 소요되기 때문에 구연산을 염산에 용해시켜 탄산수소나트륨과의 접촉속도를 증가하였다.If the sodium bicarbonate powder and the citric acid powder were reacted as they are, the carbon dioxide gas generation rate was too slow, and it took too much time for all the balloons to expand, so that the contact rate with sodium bicarbonate was increased by dissolving citric acid in hydrochloric acid.

그러나, 상기의 종래기술에서는 촉매제로 염산을 사용하기 때문에 염산의 유독성으로 인해 사용량을 소량만 사용할 수밖에 없었고, 촉매제인 염산을 소량만 사용하기 때문에 탄산수소나트륨과 구연산과의 접촉면적 및 반응속도를 향상시키는데에는 한계가 있을 수밖에 없었다. 이를 극복하기 위해서는 탄산수소나트륨을 일정면적 내에 담아두는 큰 봉지(2)를 추가로 사용해야함으로 제조공정이 복잡하고 제조원가가 상승하는 문제가 있었다.However, in the above prior art, since hydrochloric acid is used as a catalyst, only a small amount of hydrochloric acid is used, and since only a small amount of hydrochloric acid is used as a catalyst, the contact area and reaction rate of sodium bicarbonate and citric acid are improved. There was no limit to this. In order to overcome this problem, a large bag (2) containing sodium bicarbonate in a certain area should be additionally used, resulting in a complicated manufacturing process and an increase in manufacturing cost.

또한, 상기의 종래기술에서는 촉매제로 염산을 사용하기 때문에 막대풍선의 폐기시 환경오염 문제가 발생 되었다.In addition, in the above prior art, since hydrochloric acid is used as a catalyst, an environmental pollution problem occurs when the bar balloon is disposed.

또한, 상기의 종래기술에서는 앞에서 설명한 바와 같이 촉매제인 염산을 소량만 사용해야 하기 때문에 이를 밀봉하는 작은 봉지(1)의 부피감(팽창감)이 거의 없어서 사용시 작은 봉지(1)를 손바닥 등으로 가볍게 눌러주거나 타격하는 방식으로 작은 봉지(1)를 터트릴 수가 없었다. 그 결과 종래기술에서는 작은 봉지(1)를 터트리기 위해서 별도의 돌출핀(3)을 구비해야 하기 때문에 제조공정이 복잡하고 제조원가도 상승하고, 사용도 번거러운 문제 등이 있었다.In addition, in the above-mentioned prior art, since only a small amount of hydrochloric acid, which is a catalyst, must be used as described above, there is little volume (expansion) of the small bag 1 that seals it, so that the small bag 1 is lightly pressed with a palm or the like during use. Could not break the small bag (1) in the way of hitting. As a result, in the prior art, a separate protruding pin 3 has to be provided to explode the small bag 1, and thus, the manufacturing process is complicated, the manufacturing cost is increased, and the use is cumbersome.

본 발명에서는 앞에서 설명한 종래의 문제점들을 모두 해결함으로써, 내부에 기체가 없는 상태로 간편하게 운반 및 휴대하다가 필요시(사용시) 손 등으로 튜브 본체내에 내장된 용액 봉지를 원 터치 방식으로 눌러주거나 타격해 터트려 주면 자기팽창 되는 튜브를 제공하고자 한다.In the present invention, by solving all the above-mentioned conventional problems, it is easy to carry and carry with no gas inside, and when necessary (when used), press or hit the solution bag built in the tube body with one-touch by hand or the like. To provide a tube that is self-expanding if given.

또한, 본 발명에서는 촉매제로서 염산 대신 다량의 물을 사용함으로써 돌출핀 등의 별도기구 없이도 촉매제가 담긴 봉지를 쉽게 터트릴 수 있고, 2중 봉지를 사용하지 않고도 구연산과 탄산수소나트륨의 접촉면적 및 속도를 향상시켜 단시간 내에 튜브를 팽창시킬 수 있고, 폐기시 환경오염 등의 오염문제가 없고, 제조원가가 저렴하고 제조공정이 간소한 원터치 타입 자기팽창 튜브를 제공하고자 한다.In addition, in the present invention, by using a large amount of water instead of hydrochloric acid as a catalyst, the bag containing the catalyst can be easily exploded without a separate mechanism such as a protruding pin, and the contact area and speed of citric acid and sodium hydrogen carbonate can be improved without using a double bag. It is possible to provide a one-touch type self-expansion tube that can be expanded in a short time, there is no pollution problem such as environmental pollution during disposal, and the manufacturing cost is low and the manufacturing process is simple.

또한, 본 발명에서는 팽창된 튜브가 팽창된 상태를 보다 오랫동안 유지하는 원터치 타입 자기팽창 튜브를 제공하고자 한다.In addition, the present invention is to provide a one-touch type self-expansion tube that maintains the expanded state for a longer time.

이하, 첨부한 도면 등을 통하여 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 원터치(One-touch) 타입 자기팽창 튜브는 도 1 내지 도 2에 도시된 바와 같이 튜브본체(A) 내에 (ⅰ) 수용성 유기산이 물에 용해되어 있는 용액이 밀봉되어 있는 용액 봉지(B)와 (ⅱ) 탄산수소나트륨 분말(C)이 각각 내장되어 있는 것을 특징으로 한다.The one-touch type self-expansion tube according to the present invention is a solution encapsulation in which a solution in which water-soluble organic acid is dissolved in water is sealed in the tube body A as shown in FIGS. B) and (ii) sodium hydrogencarbonate powder (C), characterized in that the respective built-in.

또한, 본 발명은 튜브본체(A) 내에 (ⅰ) 탄산수소나트륨이 용해되어 있는 용액이 밀봉되어 있는 용액 봉지(B)와 (ⅱ) 수용성 유기산 분말(C)이 각각 내장되어 있는 것을 포함한다.The present invention also includes a solution bag (B) and (ii) a water-soluble organic acid powder (C) in which a solution in which (i) sodium hydrogen carbonate is dissolved is sealed in the tube body (A).

다시말해, 본 발명에서는 용액 봉지(B)에 밀봉된 용액으로는 수용성 유기산이 용해된 물을 사용할 수도 있고, 탄산수소나트륨이 용해된 물을 사용할 수도 있다.In other words, in the present invention, water in which the water-soluble organic acid is dissolved may be used as the solution sealed in the solution bag (B), or water in which sodium hydrogencarbonate is dissolved may be used.

용액 봉지(B) 내에 수용성 유기산이 용해된 물이 밀봉된 경우에는 튜브본체(A) 내에 탄산수소나트륨 분말을 내장하고, 용액 봉지(B) 내에 탄산수소나트륨이 용해된 물이 밀봉된 경우에는 튜브본체(A) 내에 수용성 유기산 분말을 내장한다.When the water in which the water-soluble organic acid is dissolved is sealed in the solution bag (B), the sodium hydrogen carbonate powder is incorporated in the tube body (A), and when the water in which the sodium hydrogen carbonate is dissolved in the solution bag (B) is sealed, the tube The water-soluble organic acid powder is incorporated in the main body A.

도 1은 튜브본체(A)가 막대풍선 형태인 본 발명의 단면예시도 이고, 도 2는 튜브본체(A)가 사각형인 본 발명의 단면예시도 이다.1 is a cross-sectional view of the present invention in which the tube body A is in the form of a bar balloon, and FIG. 2 is a cross-sectional view of the present invention in which the tube body A is a quadrangle.

상기 튜브본체(A)는 막대형태, 다각형 형태, 원형형태, 가운데가 중공(中空)인 도넛형태, 구명조끼 형태 등으로 다양하게 제조될 수 있다.The tube body (A) may be manufactured in various forms such as rod-shaped, polygonal, circular, hollow donut, life jacket, and the like.

상기 용액봉지(B)의 재질은 폴리에스테르 필름, 폴리비닐클로라이드 필름, 나일론 필름, 저밀도 폴리에틸렌 필름 등의 합성수지 필름인 것이 바람직하다.The material of the solution encapsulation (B) is preferably a synthetic resin film such as polyester film, polyvinyl chloride film, nylon film, low density polyethylene film.

튜브본체(A)의 재질도 폴리에스테르 필름, 폴리비닐클로라이드 필름, 나일론 필름, 저밀도 폴리에틸렌 필름 등의 합성수지 필름이며, 보다 바람직하기로는 나일론-폴리에틸렌 공압출 필름인 것이 튜브가 팽창된 상태를 오랫동안 유지하는데 바람직하다.The material of the tube body (A) is also a synthetic resin film such as polyester film, polyvinyl chloride film, nylon film, or low density polyethylene film. More preferably, the nylon-polyethylene coextrusion film keeps the tube in an expanded state for a long time. desirable.

폴리에틸렌 필름은 탄산가스 투과도가 70~80g/㎡ ·24시간 ·atm 으로 너무 높고, 나일론 필름은 탄산가스 투과도가 0.1g/㎡ ·24시간 ·atm 으로 낮으나 가격이 비싸기 때문에 이들의 공압출 필름을 사용하는 것이 바람직하다.Polyethylene film has a high carbon dioxide permeability of 70 to 80 g / m2, 24 hours, atm, and nylon film has a low carbon dioxide gas permeability of 0.1 g / m2, 24 hours, atm, but is expensive. It is desirable to.

그러나 본 발명에서는 상기의 용액 봉지(B) 및 튜브본체(A)의 재질을 특별하게 한정하는 것은 아니다.However, in the present invention, the material of the solution bag (B) and the tube body (A) is not particularly limited.

본 발명에서는 수용성 유기산의 일례인 구연산과 탄산수소나트륨이 튜브본체(A) 내에서 아래와 같은 반응식으로 반응하여 탄산가스가 발생하여 튜브가 자기팽창된다.In the present invention, citric acid, which is an example of a water-soluble organic acid, and sodium bicarbonate are reacted in the tube body A by the following reaction to generate carbon dioxide gas, thereby causing the tube to self-expand.

Figure 112007073480216-PAT00001
Figure 112007073480216-PAT00001

Figure 112007073480216-PAT00002
Figure 112007073480216-PAT00002

상기 반응식에서 알수 있듯이 구연산 1몰(mole)과 탄산수소나트륨 3몰(mole)이 반응하여 탄산가스 3몰(mole)이 발생되며, 이 같은 반응은 비가역적이다.As can be seen from the reaction scheme, 1 mole of citric acid and 3 moles of sodium hydrogen carbonate react to generate 3 moles of carbon dioxide, and this reaction is irreversible.

한편, 튜브의 부피변화에 따른 구연산과 탄산수소나트륨의 내장량 및 탄산가스의 발생량은 하기의 이상기체 방정식을 활용하여 산출할 수 있다.Meanwhile, the amount of citric acid and sodium bicarbonate and the amount of carbon dioxide generated according to the volume change of the tube may be calculated using the following ideal gas equation.

PV = nRTPV = nRT

n = PV/RTn = PV / RT

상기식에서, P는 압력(atm)이고, V는 부피(L)이고, n은 기체의 몰 수 있고, R은 이상기체 상수(0.08205ℓ·atm/mole·K)이고, T는 절대온도(273℃)이다.Where P is pressure (atm), V is volume (L), n is mole of gas, R is ideal gas constant (0.08205 l · atm / mole · K), and T is absolute temperature (273) ℃).

예를 들면 n=1 몰로 산출되면 탄산가스가 1몰이 필요하며 이는 구연산 1/3몰 과 탄산수소나트륨 1몰이 필요함을 의미한다.For example, if n = 1 mol, 1 mol of carbon dioxide is required, which means that 1/3 mol of citric acid and 1 mol of sodium bicarbonate are required.

상기의 수용성 유기산은 본 발명품이 폐기혹은 훼손되었을 경우 인체 및 환경에 악영향을 미치지 않아야 되기 때문에 식품첨가용 수용성 유기산인 것이 바람직하다. 통상 탄산수소 나트륨은 이들 식품 첨가용 유기산 외에도 염산, 황산, 질산, 옥살산(수산) 등등의 산류와도 반응에 의해 탄산가스를 발생시키지만 인체에 유해하기 때문에 바람직하지 못하다. The water-soluble organic acid is preferably a water-soluble organic acid for food additives because the present invention should not adversely affect the human body and the environment when the present invention is discarded or damaged. In general, sodium hydrogen carbonate generates carbon dioxide by reaction with acids such as hydrochloric acid, sulfuric acid, nitric acid, oxalic acid (hydroxyl acid), etc. in addition to organic acids for food addition, but is not preferable because it is harmful to the human body.

상기 수용성 유기산으로는 젖산(Lactic Acid), 아스코르빈산, 탄닌산, 구연산, 초산, 사과산, 푸말산, 글루콘산, 호박산 또는 이들의 혼합물들을 사용할 수 있으며, 보다 바람직 하기로는 구연산을 사용하는 것이 좋다.Lactic acid, ascorbic acid, tannic acid, citric acid, acetic acid, malic acid, fumaric acid, gluconic acid, succinic acid or mixtures thereof may be used as the water-soluble organic acid, and more preferably citric acid may be used.

상기 구연산(citric acid) 은 자연에 존재하는 동식물의 대사물질로서 감귤류에서 가장 많이 얻을 수 있는 유기산이며,상쾌한 신맛을 나타내는 산미제, pH조절제, 산화방지제, 수렴제 등으로 다양하게 사용되는 식품첨가용 유기산이다.Citric acid (citric acid) is an organic acid most obtainable from citrus fruits as a metabolite of animals and plants existing in nature, organic acid for food additives used in various ways such as acidifiers, pH regulators, antioxidants, astringents etc. to be.

본 발명에서 사용된 탄산수소나트륨은 인류 오랜 역사 동안 식품의 팽창제로 사용되고 있는 물질로서 식품첨가용이다.Sodium bicarbonate used in the present invention is a food additive as a substance that has been used as a food expanding agent for a long history of humanity.

한편, 본 발명은 촉매제로서 종래의 염산 대신에 물을 사용하는 것을 특징으로 한다.On the other hand, the present invention is characterized by using water instead of conventional hydrochloric acid as a catalyst.

본 발명에서는 상기와 같이 촉매제로서 유해성이 없는 물을 사용하기 때문에 이의 사용량에 특별한 제한이 없는 장점이 있다.In the present invention, since there is no harmful water as a catalyst as described above, there is an advantage that there is no particular limitation on the amount of its use.

이로인해 물의 사용량을 적절하게 높혀 줌으로써 첫째 구연산과 탄산수소나 트륨의 반응속도 및 접촉속도를 상승시켜 보다 빠른 시간 내에 튜브를 팽창할 수 있고, 둘째 용액봉지(B)에 부피감(팽창감)을 원하는데로 부여할 수 있어서 손바닥으로 이를 가볍게 타격해 주는 등의 원터치 방식으로도 쉽게 용액 봉지(B)을 터트릴 수 있어서 돌출핀 등과 같이 용액 봉지를 터트리기 위한 별도 기구가 필요없게 된다.This increases the reaction rate and contact speed of citric acid and hydrogen carbonate or sodium by appropriately increasing the amount of water used, so that the tube can be expanded in a faster time, and second, the volume (expansion) of the solution bag (B) is desired. It can be given so that the solution bag (B) can be easily exploded in a one-touch manner, such as lightly hitting it with the palm, there is no need for a separate mechanism for popping the solution bag, such as a protruding pin.
