Abstract

A gas filler structure is provided.
[MEANS FOR SOLVING PROBLEMS] Three hydrophilic osmotic resin layers are mainly provided on the inner wall surface of a hollow cloth body, and at least one continuous S-shaped joining line (35) forming a sealed arc-shaped joining line (351) at both ends is provided outside the hollow cloth body. Both sides of the wall surface 312 are joined. Thereby, the three hydrophilic osmotic resin layers of the gas-filled body structure of the present invention are lightweight and have a waterproof osmotic heat retaining effect. In addition, since the width of the continuous S-shaped joining line is narrow, the amount of gas accommodated in the hollow cloth body 31 is increased, and the continuous S-shaped joining line is difficult to break, and the gas stored in the hollow cloth body leaks out. Thus, the gas filling structure 3 of the present invention is robust, lightweight, and has an optimal waterproof penetration heat retaining effect.

Description

  The present invention relates to a kind of gas filling structure. In particular, three hydrophilic permeation resin layers are installed on the inner wall surface of a kind of hollow cloth body, and both sides of the outer wall surface of the hollow cloth body are joined by at least one continuous S-shaped joining wire that forms a sealed arc-shaped joining wire at both ends. It relates to a gas filling structure.

  In winter when the climate is cold, people often wear winter clothing such as down jackets when going out. Since the down jacket is provided with feathers, it contains air and is inflated softly. In this way, the down jacket cuts off the cold in the outside world with air and feathers.

  However, when the down jacket receives external force and is compressed to discharge air, the heat retaining effect is reduced. In addition, the down jacket uses bird feathers, so there is a problem of off-flavor, and attention should be paid to infection with avian influenza. Furthermore, people with special constitutions must be careful about allergies.

  For this reason, gas-filled structures such as gas-filled clothing have been developed. The gas-filled garment forms a gas-filled space sealed on both sides of the gas-filled garment by various joining methods. The gas-filled space is very convenient to use because it can inject an appropriate amount of air by itself and block the cold air from the outside based on the user's need for heat insulation.

  However, the resin layers used in the known gas filling structure are divided into about three types, all of which have drawbacks.

  First, in the case of a PVC material, the bonding strength is weak, and the thickness of the resin layer needs to be 0.15 mm to 0.20 mm in order to satisfy the bonding strength required under general conditions. Moreover, if the thickness of the resin layer is thick, the weight of the resin layer is indirectly increased. In addition, PVC materials are not permeable and generate dioxins after combustion, which has an adverse effect on the environment.

  Next, TPU materials are thick, heavy, non-permeable, hard to touch, and expensive to process.

  Lastly, the TPU ventilation material has a low bonding strength, low gas retention, a particularly high processing cost, and a high processing abnormality rate.

  Furthermore, the known gas-filled structure also has drawbacks in its joining method. Although FIG. 1 is a three-dimensional view of a known gas filler structure, as shown in the figure, the resin layer used by the known gas filler structure 1 has a low bonding strength, so the bonding width of the bonding line 11 is wide. The wide joint line 11 easily leaks warm air around the human body from here, and cold air from the outside easily enters from here, and thus the heat retaining effect is lowered. Further, the wide joining line 11 reduces the amount of air that can be accommodated by the known gas filler structure 1 and further reduces the heat retention effect. Furthermore, since both ends of the joining line 11 are not combined, stress is likely to concentrate on the position. For example, when the known gas filler structure 1 is compressed by a relatively large external force, the joining line 11 is likely to break from both ends. Air leaks easily.

  FIG. 2 is a three-dimensional view of another known gas filler structure, but as shown in the figure, the joint shape used by another known gas filler structure 2 is circular. Although this structure has improved the problem of stress concentration, the joint diameter of the joint circle 21 is also large because the joint strength of the resin layer is weak, and the warm air around the human body is likely to leak from here due to the large joint circle 21. Also, the outside cold is easy to enter from here. Therefore, the heat retention effect is reduced. In addition, the large joining circle 21 reduces the amount of air that can be accommodated by another known gas filling structure 2, which also reduces the heat retention effect.

  The problem to be solved by the present invention is how to devise a solid and lightweight gas-filled structure and to exert the optimum waterproof penetration heat retaining effect.

  In order to solve the above problems, the present invention provides the following gas filling structure.

  In light of the above-noted achievements in the known gas filling structure, the present inventors have conducted research and developed a gas filling structure with many years of experience in the industry. This provides a gas-filled structure that is robust, lightweight, and has an optimal waterproof penetration heat retaining effect.

  The main object of the present invention is to provide a gas-filled structure, in which three hydrophilic permeable resin layers are provided on the inner wall surface of the hollow cloth body, and at least one continuous S forming a sealed arc-shaped joining line at both ends. The purpose is to join the both sides of the outer wall surface of the hollow cloth body with a shape joining line, the hollow cloth body is solid and has a relatively large gas filling space, and thus the gas filling structure is solid and lightweight and has the optimum waterproof penetration heat retaining effect That is, the gas-filled structure of the present invention has the following structure, the hollow cloth body has an inner wall surface and an outer wall surface, and the solvent-type hydrophilic penetrating resin layer is installed on the inner wall surface, The osmotic resin layer is installed on the solvent-type hydrophilic osmotic resin layer, the low melting point hydrophilic osmotic resin layer is installed on the low coefficient hydrophilic osmotic resin layer, and the low melting point hydrophilic osmotic resin layer is a gas-filled space. And at least one continuous S-shaped connecting line is on both sides of the outer wall. Joining, thereby limiting the thickness of the gas filling of the hollow cloth body, both ends of the continuous S-shaped joining line form a sealed arc-shaped joining line, the gas filling outlet is installed in the hollow cloth body, The gas filling space leads to the gas filling space, thereby filling or discharging the gas filling space, so that the gas filling structure of the present invention provides a gas filling structure having a strong, lightweight and optimum waterproof penetration heat retaining effect.

  As described above, the present invention is consistent with the three requirements of the utility model, novelty, inventive step, and industrial applicability. In terms of novelty and inventive step, the present invention is hollow by at least one continuous S-shaped joint line in which three hydrophilic permeable resin layers are installed on the inner wall surface of the hollow cloth body and a sealed arc-shaped joint line is formed at both ends. By joining both sides of the outer wall surface of the cloth body, the hollow cloth body is solid and has a relatively large gas filling space, and thus the structure of the gas filling body is solid, lightweight, and has the effect of providing the optimum waterproof penetration heat retaining effect. To do. With regard to industrial applicability, products manufactured according to the present invention can fully meet current market needs.

  Specific examples will be described in detail below with reference to the drawings so that the purpose, features, and functions of the present invention can be fully understood.

  3 to 7 are a three-dimensional view and a sectional view of the first optimum specific embodiment of the present invention, respectively, and a three-dimensional view of the second, third and fourth specific embodiments of the present invention. As shown in the figure, the gas-filled body structure 3 of the present invention has a hollow cloth body 31, a solvent-type hydrophilic osmotic resin layer 32, a low coefficient hydrophilic osmotic resin layer 33, a low melting point hydrophilic osmotic resin layer 34, and at least one continuous layer. An S-shaped joining line 35 and a gas filling / exhaust port 37 are included.

  The hollow cloth body 31 includes an inner wall surface 311 and an outer wall surface 312, and the material of the hollow cloth body 31 is nylon, nylon 66, or tetron.

  The solvent type hydrophilic osmotic resin layer 32 is placed on the inner wall surface 311, and the solvent type hydrophilic osmotic resin layer has a high osmotic force, and strengthens the adhesive force between the solvent type hydrophilic osmotic resin layer 32 and the inner wall surface 311. can do.

  The low-coefficient hydrophilic osmotic resin layer 33 is placed on the solvent-type hydrophilic osmotic resin layer 32, and the low-coefficient hydrophilic osmotic resin layer 33 makes the hollow fabric body 31 have a soft and plentiful hand.

  The low melting point hydrophilic osmotic resin layer 34 is placed on the low coefficient hydrophilic osmotic resin layer 33, and the low melting point hydrophilic osmotic resin layer 34 seals the gas filling space 36. The low melting point hydrophilic penetrating resin can be easily processed and bonded with low melting point characteristics, and can further enhance the bonding strength.

The thicknesses of the three hydrophilic penetrating resin layers 32, 33, and 34 are 0.03 mm to 0.05 mm, and an optimum example is 0.05 mm. Its thickness is thin, so its weight is light (60-70g / m ² ).

  The continuous S-shaped joining line 35 that forms the sealed arc-shaped joining line 351 at both ends is formed by high-frequency joining, ultrasonic joining, or heat fusion joining, and joined to both sides of the outer wall surface 312, thereby the hollow cloth body 31. Limit the thickness of the gas filling. The best example is the formation by high-frequency bonding, and the bonding strength reaches 150N / 5cm. In addition, since the continuous S-shaped joint line 35 that forms the sealed arc-shaped joint line 351 at both ends can disperse the stress on the average, even if the gas filling structure 3 is subjected to a relatively large external force, the stress is not reduced. There is no concentration and no destruction occurs. Further, the width is 1 mm to 2 mm, and the optimum example is 2 mm. Since the width is narrow, the volume of the gas filling space 36 is increased, and thus the heat retaining effect is improved.

  The gas filling outlet 37 is installed in the hollow cloth body 31 and communicates with the gas filling space 36. The gas filling space 36 can blow or discharge an appropriate amount of air from the gas filling / ejecting port 37 by itself as required by the user to keep warm.

  Using the gas-filled body structure 3 of the present invention, a gas-filled cap 4, a gas-filled ear cover 5, a gas-filled garment 6, a gas-filled glove 7, a gas-filled trouser 8, a gas-filled sleeping bag 9, or a gas-filled comforter 10 is manufactured. Can do.

  When the gas-filled body structure 3 is produced in the gas-filled garment 6, moisture discharged by the human body passes through the hollow cloth body 31, is absorbed by the solvent-type hydrophilic osmotic resin layer 32, and further, the low coefficient hydrophilic osmotic resin. Moisture is discharged into the outside atmosphere by the drainage movement between the layer 33 and the low melting point hydrophilic permeation resin layer 34. Thus, the warm air around the human body is stored inside without the human body feeling hot and humid. Moreover, since external cold wind and rainwater are isolated outside by the gas-filled clothes 6 and do not penetrate into the resin layer, windproof and waterproof effects, and ventilation and heat insulation effects can be achieved simultaneously.

  Further, three ventilation holes 61 are provided on the armpits on both sides of the gas-filled garment 6 to provide a function of ventilating sweat under the human armpit.

  The gas-filled structure of the present invention utilizes a solvent-type hydrophilic osmotic resin and can enhance the adhesive force by high frequency bonding (150 N / 5 cm), thereby extending the service life of the gas-filled structure.

The three hydrophilic permeable resin layers have high moisture permeability (5000g / m ² or more), high waterproofness (10000M / M or more), thin thickness (0.05mm or less), and light weight (60-70g / m ² ) Since the touch is flexible, it is possible to provide an optimal feeling of comfort during use.

  Furthermore, the processing method of the resin layer can be a traditional upper resin coating method, so the processing cost is low.

  In addition, the continuous S-shaped joint line that forms a sealed arc-shaped joint line at both ends disperses the stress on average, so it does not concentrate at a certain place, even if the gas filling structure receives a relatively large external force, A continuous S-shaped joint line that forms a sealed arc-shaped joint line at both ends is difficult to break. In addition, since the width is 2 mm or less, the gas filling volume of the hollow cloth body can be increased and the cold protection effect can be improved.
