Abstract
A one-touch type self-inflatable tube comprises a tube body A containing a solution pouch B and a powder C. The sealed solution pouch B contains either a solution of a water-soluble organic acid in water when the powder comprises sodium bicarbonate, or contains a solution of sodium bicarbonate in water when the powder comprises water-soluble organic acid powder. The organic acid may be at least one selected from, or a mixture of lactic, ascorbic, tannic, citric, acetic, malic, fumaric, gluconic, and succinic acid. The self-inflatable tube according to the present invention reduces the work of introducing external gas into the tube, provides simple self-inflation equipment which is convenient to manage and reduces production costs. The tube may be used in the manufacturing of practical articles such as stick balloons often used as cheering tools, water tools, air cushions or life-jackets.
Description
ONE-TOUCH TYPE SELF-INFLATABLE TUBE
BACKGROUND OF THE INVENTION
This application claims priority to Korean Patent Application No. 2007-0103316, filed on October 15, 2007, in the Korean Intellectual Property Office, the entire contents of which are hereby incorporated by reference.
1. Field of the Invention
The present invention relates to one-touch type sell-inflatable tubes, more particularly, a one-touch type self-inflatable tube that can be conveniently and simply carried and delivered without gaseous contents at normal times and, when it is required, is self-inflated by pressing or hitting a solution pouch B included in the tube by hand to burst and/or tear the pouch and, thus, can be immediately used.
The term tube" in the present application generally means stick balloon often used as one of cheering tools, sword type balloon as toy for children, water tools such as swimming tube, air cushion, life-jacket, etc.
2. Description of the Related Art
As illustrated in Fig. 3, a conventional tube such as stick balloon has an air inlet part D fabricated by setting up a check valve D2 (for introducing air) in an opening part Dl on a part of the tube and heat fusing the opening part Dl. Thus, when using the tube, there is a requirement to introduce air through the check valve D2 into a tube body A. Fig. 3 is a cross-sectional view illustrating the conventional stick balloon type tube.
As described above, the conventional tube needs alternative work to introduce a gas into the tube body A in order to use the tube, which is moderately bothersome. In case of using the tube where there is no gas injection tool, the tube is often carried after pre-introduction of gas which results in inconvenience in cariying and delivering the tube.
Alternatively, if gas is introduced into the tube body A through mouth of a person, there are difficulties such as long time and quite a bit of effort required.
As another method proposed in the related parts in order to solve the problems described above, Korean Patent Laid-Open No. 2006- 0134407 disclosed a self-inflatable stick balloon which generates gas inside the stick balloon and self inflates by pricking a small pouch 1 with a protrusion pin 3 to induce a reaction of citric acid and sodium bicarbonate, even if external gas is not introduced therein, characterized in that the balloon is equipped with a gas generator E at one side thereof, comprising: (i) a small pouch 1 containing a solution prepared by dissolving citric acid in hydrochloric acid; (ii) a larger pouch 2 including the small pouch 1 and sodium bicarbonate powder; and (iii) a protrusion pin 3 for perforating the small pouch 1 if it is required, as shown in Fig. 4.
Fig. 4 is a cross-sectional view illustrating the stick balloon disclosed in Korean Patent Laid-Open No. 2006-0134407.
For the stick balloon illustrated in Fig. 4, the solution contained in the small pouch 1, which is citric acid dissolved in hydrochloric acid, contacts sodium bicarbonate powder in the larger pouch 2 when the small pouch 1 is torn or pierced by the protrusion pin 3, induces the reaction of citric acid and sodium bicarbonate to cause generation of carbon dioxide gas and expansion of the larger pouch 2 and, thus, bursts the larger pouch 2. As a result, carbon dioxide gas is diffused into the entire inside of the stick balloon so that the stick balloon is self-inflatable without introduction of external gas.
Herein, hydrochloric acid contained in the small pouch 1 plays a role of catalyst.
If sodium bicarbonate powder directly reacts with citric acid powder, carbon dioxide gas is very slowly generated and requires a lot of time to completely inflate the balloon. Therefore, using hydrochloric acid to dissolve citric acid increases contact velocity between citric acid and sodium bicarbonate.
However, since this method uses hydrochloric acid as a catalyst, amount of hydrochloric acid must be securely restricted due to inherent toxicity of hydrochloric acid. Also, as the hydrochloric acid catalyst was used in only a small amount, improvements in contact area and/or reaction velocity between sodium bicarbonate and citric acid were inevitably restricted. In order to overcome these problems, there was required an additional pouch 2 with greater volume to carry sodium bicarbonate within a restricted area, thereby causing a production process to be more complicated and increasing production costs.
Moreover, the hydrochloric acid catalyst disclosed in the above conventional method causes environmental pollution when the stick balloon is discarded.
According to the above conventional method, because amount of hydrochloric acid to be used must be securely limited, the small pouch I containing hydrochloric acid in a sealed condition has substantially little bulk feeling and, therefore, cannot be burst and/or torn by lightly pressing or hitting the pouch with an open hand.
Consequently, the known method necessarily used alternative protrusion pin 3 to burst and/or tear the small pouch 1 and, as a result, caused several problems such as complicated production processes, increase of production costs, and difficulties in handling the stick balloon.
SUMMARY OF THE INVENTION
Accordingly, the present invention is directed to solve the problems described above in regard to conventional methods and an object of the present invention is to provide a one-touch type self-inflatable tube that can be conveniently and simply carried and delivered without gaseous contents at normal times and, when it is required, can derive self-inflation by pressing or hitting a solution pouch B included in the tube by hand to burst and/or tear the pouch and, thus, can be immediately used.
Another object of the present invention is to provide a one-touch type self-inflatable tube with a plurality of advantages in that: it can easily burst and/or tear a pouch containing the catalyst without requiring alternative tools by using plenty of water as a catalyst in place of hydrochloric acid; improve contact area and contact velocity for reaction of citric acid and sodium bicarbonate without use of double pouches to inflate the tube in a short time; and eliminate environmental pollution problems at disposal of the tube; and fabricate the tube by a simple process with reduced production costs.
A still further object of the present invention is to provide a one-touch type self-inflatable tube capable of maintaining an inflated state for a much longer time.
Hereinafter, the present invention will be described in detail below with reference to the accompanying drawings.
As shown in Fig. 1 and Fig. 2, a one-touch type self-inflatable tube according to an embodiment of the present invention comprises a tube body A, a solution pouch B containing (i) a solution of a water-soluble organic acid in water and being sealed, and (ii) sodium bicarbonate powder C, wherein the solution pouch B and sodium bicarbonate powder C are included in the tube body A, respectively.
According to another embodiment of the present invention, there is provided a one-touch type self-inflatable tube, comprising a tube body A, a solution pouch B containing (i) a solution of sodium bicarbonate in water and being sealed, and (ii) a water-soluble organic acid powder C, wherein the solution pouch B and the water-soluble organic acid powder C are included in the tube body A, respectively.
In other words, with regard to the present invention, the one-touch type self-inflatable tube may use the water-soluble organic acid in water or the sodium bicarbonate in water as the solution contained in the solution pouch B. In case of pouring the water-soluble organic acid in water into the solution pouch B and sealing the same, sodium bicarbonate powder is directly included in the tube body A. Conversely, if the solution pouch B contains sodium bicarbonate in water then is sealed, the water-soluble organic acid powder is directly included in the tube body A. Fig. 1 is a cross-sectional view illustrating a one-touch type self-inflatable tube according to an embodiment of the present invention, which has a tube body A in a form of stick balloon, and Fig. 2 is a cross-sectional view illustrating a one-touch type self-inflatable tube according to another embodiment of the present invention, which has a tube body A in a rectangular form.
The tube body A may be fabricated in the form of any one selected from stick, polygon, circle, hollowed donut and life-jacket without limitation thereto.
The solution pouch B may be prepared of any one synthetic resin materials selected from polyester film, polyvinylchloride film, nylon fun and low density polyethylene film, etc. without limitation thereto.
The tube body A also may be prepared of any one synthetic resin materials selected from polyester film, polyvinylchloride film, nylon film and low density polyethylene film, etc. without limitation thereto. More preferably, the tube body A is made of nylon-polyethylene co-extrusion film in order to maintain inflation of the tube for quite a long term.
Polyethylene film has too high a carbon dioxide permeability, ranging from 70 to 80g/m2O24hoursOatm while nylon film is very expensive although it has relatively low carbon dioxide permeability of about 0. lg/m2ll24hoursflatm. Accordingly, the present invention preferably uses a co-extrusion film of the polyethylene film and the nylon film.
However, materials for the solution pouch B and the tube body A are not particularly limited in the present invention.
According to the present invention, citric acid as an example of water-soluble organic acids and sodium bicarbonate are reacted together in the tube body A by the following reaction scheme, to generate carbon dioxide and derive self inflation of the tube: H3C6H507 + 3NaHCO3 Citric acid sodium bicarbonate Na,3C6H507 + 3H20 + 3C02 -, Sodium citrates water carbon dioxide As shown in the above reaction scheme, 1 mole of citric acid reacts with 3 moles of sodium bicarbonate to generate 3 moles of carbon dioxide and this is an irreversible reaction.
Required potential content of citric acid and sodium bicarbonate depending on variation in volume of the tube and generation rate of carbon dioxide can be calculated according to the following ideal gas state equation: PV=nRT n = PV/RT wherein P is pressure (atm), V is volume (L), n is number of moles of gas, R is ideal gas constant (0.08205 literOatm/moleOK) and I is absolute temperature (2730).
For example, if n = imole, 1 mole of carbon dioxide is required and means that amounts of citric acid and sodium bicarbonate required are 1/3 mole and 1 mole, respectively.
Such water-soluble organic acid must not adversely affect human body and environments when the present inventive products are discarded and/or damaged, therefore, preferable are water-soluble organic acids for food additives. In general, sodium bicarbonate can react with inorganic acids such as hydrochloric acid, sulfuric acid, nitric acid, oxalic acid, etc. to generate carbon dioxide, other than the above water-soluble organic acids for food additives. However, carbon dioxide generated from these inorganic acids is harmful to human body and is not preferable to use in the present invention.
The water-soluble organic acid is not particularly limited, but includes lactic acid, ascorbic acid, tannic acid, citric acid, acetic acid, malic acid, fumaric acid, gluconic acid, succinic acid and mixture thereof and, preferably, is citric acid.
Citric acid is one of metabolic materials in animals and plants, which is an organic acid for food additives mostly obtainable from citrus fruits and useful in a variety of applications such as acidulant for fresh acidic taste, pH control agent, anti-oxidant, astringent, etc. Sodium bicarbonate used in the present invention is a material for food additives, which is well known to function as an expansion agent for foods.
The present invention also uses water in place of hydrochloric acid previously used as a catalyst.
Because the present invention uses water which is harmless to human body as the catalyst, it is advantageous as there is no particular restriction on amount of water to be used.
Therefore, first of all, contact velocity and/or reaction velocity for reaction of citric acid and sodium bicarbonate are increased by appropriately increasing the water amount to be used, which results in faster inflation of the tube. Also, because of endowing desirable bulk feeling to the solution pouch B, the pouch can be easily burst in one-touch mode including, for example, lightly hitting the pouch with an open hand, therefore, does not require alternative tools such as a protrusion pin to burst and/or tear the solution pouch.
The one-touch type self-inflatable tube according to the present invention is preferably fabricated by a process comprising the steps of: preparing a tube body A made of synthetic resin film, which has an opening at one side of the tube body; introducing the solution pouch B as described above and citric acid powder or sodium bicarbonate powder C into the tube body A, respectively; and heat fusing the opening.
In order to first carry the one-touch type self-inflatable tube of the present invention without gaseous contents, then, inflate the tube for use, the solution pouch B in the tube body A is burst and/or torn by hitting the solution pouch B with the open hand to admix citric acid and sodium bicarbonate together to derive reaction thereof and generate carbon dioxide, thereby accomplishing self inflation of the tube.
The present invention discloses a one-touch type self-inflatable tube, characterized in that the tube can be simply and conveniently carried and delivered without gaseous contents and, if it is required, can be self inflated by pressing or hitting a solution pouch placed in a tube body by hand.
The one-touch type self-inflatable tube according to the present invention has a plurality of advantages in that: a pouch containing the catalyst can be easily burst and/or torn without requiring alternative tools by using plenty of water as a catalyst in place of hydrochloric acid; contact area and contact velocity for reaction of citric acid and sodium bicarbonate are improved without use of double pouches to inflate the tube in a short time; and environmental pollution problems at disposal of the tube are eliminated; and the tube can be fabricated by a simple process with reduced production costs.
The present inventive tube can maintain an inflated state for a much longer time.
Accordingly, the one-touch type self-inflatable tube according to the present invention is effective to manufacture a variety of articles including, for example, stick balloon often used as one of cheering tools, toys for children, air cushion, life-jacket, water tools such as swimming tube, boat parts, etc.
