It relates to a fluid filler having a.

In general, cushioning packaging materials have been used, such as lightweight, shock-absorbing styrofoam, sponge, etc., but because of the bulky, difficult handling, and has the disadvantage of polluting the environment, in recent years, the air to compensate for these disadvantages Injectable packaging packs are proposed.

Air-injectable packaging packs are formed by fusion of the plastic packaging film in the horizontal and vertical directions to form an air bag, and each air bag is provided with a valve to inject air through the valve. In addition, the valve is arranged to form one or two valve films, but forming a release portion that is not bonded to each other when fused to form an injection passage for the injection of air.

As described above, the air-injection packaging pack is formed by a film paper and is configured in the air-injection method to perform a cushioning function, and thus has an advantage of easy handling and not causing environmental pollution. Due to these advantages, Republic of Korea Patent Publication No. 10-0547578, Republic of Korea Patent Publication No. 10-2009-0101553, Republic of Korea Patent Publication No. 10-0731542, Republic of Korea Patent Publication No. 10 As shown in -2009-0115240, various research and development activities are in progress.

For example, as shown in FIG. 1 and FIG. 2, the air-packed packing pack has a valve film 2 disposed on the inner side between the overlapping packing films 1 and 1a having an outer line, and the packing film 1, A plurality of air pockets 3 are constituted by an adhesive line 7 formed by adhering the outer periphery of 1a) and a plurality of rows of partition lines 6.

Then, the air injection passage (4) formed by the release portion 10 formed in the valve film (2) so as not to be bonded to each other at the time of fusion, and the air supply chamber (8) containing the air supplied to the air injection passage (4) Is provided, and a main air inlet (9) for injecting outside air is formed at one end of the air supply chamber (8).

As shown in FIG. 2, when the air is injected through the air injection passage 4 in the state in which the valve film 2 is in close contact with the upper packaging film 1 as illustrated in FIG. The tip end of the) is opened downward and the air is introduced into the air bag (3) to be filled. When the air is filled in the air bag 3 as described above, the valve film 2 is returned to its original position by the internal pressure and closes to the inner surface of the upper packaging film 1.

However, the conventional air-injected packing pack described above functions as a packing pack because when the external force such as vibration or shock is applied from the outside, the tip of the valve film 2 is opened and the air in the air bag 3 is exhausted. It has limitations that cannot be performed perfectly and does not ensure sufficient safety.

In particular, the conventional air-injectable packaging pack is in a situation that can not be applied to the material of the product, such as cushions, sheets, etc. because the valve film (2) can not be easily maintained when the irregular load is applied.

In the conventional air-injection packing pack, when the air bag 3 is formed in various directions, the air supply chamber 8 and the main air inlet 9 need to be separately provided in each direction, which leads to waste of raw materials and a manufacturing process. This complexity not only increases the manufacturing cost but also has the disadvantage of lowering productivity.

In addition, when the filling operation is completed, the air supply chamber 8 and the main air inlet 9 have a shape in which the utility disappears and the air supply is removed, and thus the aesthetic appearance is poor. In addition, if the removal is necessary, a separate removal process is required, which increases the manufacturing cost. Leaving it for refilling later may result in poor appearance and inconvenience in handling.

To help. Then, one surface treatment part is formed at one end of the valve film 140 to configure the external fluid supply path 109b after the fusion process is performed.

Subsequently, the valve film 130 is overlapped to the bottom of the valve film 140 to be disposed on the inner surface of the first envelope film 110, and then a fusion process is performed to form a fluid filler. That is, the valve fusion line 108 is formed through the fusion process so that the valve films 130 and 140 are fused to the first outer film 110, and the outer fusion line at the edges of the first and second outer films 110 and 120. A plurality of compartment fusion lines 107 are formed at predetermined intervals so as to form the 106 and form the desired fluid filling chamber 101 in the transverse direction. At this time, since the surface treatment portion 109c located in the valve fusion line 108 and the section fusion line 107 is not fused to each other even after the fusion process, the fluid movement path 109a and the external fluid supply path 109b are formed. do.

When the fusion process is performed, the flow path changing fusion unit 103 for positioning the fluid injection path 102 at both edge portions and the extension valve fusion units 104 and 105 for fixing the extension valve unit 131 are formed. .
