When the first fusion line 22a is formed, the inner sheet 30 and the endothelial 10 are not bonded to each other due to the heat-resistant member 31, so that only the inner sheet 30 and the outer shell 20 are bonded to each other. A pressure passage 31A is formed between the inner sheet 30 and the outer shell 20. The pressure passage 31A will be described in detail later.

In addition, since the first fusion portion 33 overlaps and heat-bonds wider than the application width of the heat resistant member 31 along the first fusion line 22a, an intermediate portion of the first fusion portion 33 (the The portion overlapping with the heat resistant member 31 is only the inner sheet 30 and the outer shell 20 are thermally bonded to each other, the upper portion and the lower portion of the first fusion portion 33 is the inner shell 10 and While both the outer shell 20 and the inner sheet 30 are thermally bonded, the outer shell is formed by the first fusion line 22a and the first fusion portion 33 between the adjacent first fusion portions 33. The passage in which the inner sheet 30, which is thermally bonded to 30, is formed to be spaced apart from the endothelial 10, is characterized by functioning as a first passage 33A in communication with the air injection portion 22.

At this time, since the heat-resistant ink is continuously applied in the drawings of the present specification, the first passage communicates along the longitudinal direction of the heat-resistant ink to form an auxiliary air injection passage, which is the coating of the heat-resistant ink as described above. It may be formed differently according to the section (for example, when discontinuous application of the heat ink) which can be implemented in various modifications according to the choice of those skilled in the art should not be limited to the interpretation of the present invention.

Therefore, since the first fusion portion 33 is formed to be wider than the width of the heat-resistant ink is applied in the vertical direction (the direction perpendicular to the longitudinal direction in which the heat-resistant ink is applied) (the first fusion portion extends to the air injection portion at this time) The inner portion and the outer portion of the first fusion portion are bonded to each other while the inner shell 10 and the outer shell 20 are bonded to each other between the upper portion of the neighboring first fusion portion 33. An inlet of the air supply valve (hereinafter referred to as a first supply part 33a) is formed, and an intermediate portion of the first fusion part 33 includes the outer shell 30, the inner sheet 20, and the inner shell ( The second supply part 33b connected to the first supply part 33a is formed between the adjacent middle parts of the first fusion part 33 while 10 is thermally bonded to each other, and a lower portion of the first fusion part 33 is formed. The inner shell 10 and the outer shell 20 are bonded to each other while the neighboring portion of the lower first fusion unit 33 Thus it is formed a third supply part (33c) connected to the second supply part (33b).

Hereinafter, the configuration through the first fusion unit 33 will be referred to collectively as first to third supply units, which is formed by air through a first passage 33A formed between neighboring first fusion units as described above. It is a structure for demonstrating supply, and it does not supply air directly through a said 1st fusion | melting part.

The first supply part 33a of the present invention has a function of guiding the air injected into the air injection part 22 to the air filling part 21. Therefore, the air injected into the air injection unit 22 opens the first passage 33A formed between the inner sheet 30 and the endothelium 10 (the first supply unit 33a) and the first passage. The air filling into the air filling portion proceeds via 33A.

Subsequently, the air supply valve according to the present invention includes a second fusion unit 34 corresponding to the first fusion unit 33 as illustrated in FIGS. 1 to 5, and the second fusion unit ( 34 is thermally bonded to each other only a portion of the inner shell 10 and the inner sheet 30, the passage formed between the adjacent second fusion (that is, the non-welded) is the first passage (33A) and Connected to the second passage 34A.

In addition, the air supply valve further comprises a third fusion unit 35 is formed spaced apart from the second fusion unit 34, the third fusion unit 35 is the inner shell 10 and the inner sheet A portion of the 30 is thermally bonded to each other so that a passage formed between the adjacent third fusion portions 35 (that is, the non-fusion portion) is connected to the second passage 34A to extend the air path. It functions as a third passage 35A.

That is, the second fusion unit 34 is connected to the first fusion unit 33 and a part of the inner sheet 30 and the endothelium 10 in a direction perpendicular to the longitudinal direction of the heat resistant member 31. Is preferably formed in a bonded form, the second passage (34A) is formed of the same or similar width as the first fusion unit 33 and the air can be supplied between the adjacent second fusion unit 34 Is formed to facilitate the air supply to the air filling unit 21 and at the same time function as the air supply valve to be described later can prevent the air outflow through the double seal.

In the drawings of the present specification, the second fusion unit may be formed to overlap with the first fusion unit 33 and may be formed in a shape similar to '口' in consideration of the convenience of manufacturing and expansion and contraction during air filling. The second fusion portion can be deformed into any form capable of performing the above functions.

In addition, the third fusion portion 35 is configured on the lower extension line of the second passage 34A, and the third fusion portion 35 also has a portion of the inner sheet 30 and the endothelial 10 bonded thereto. It is formed in the form, the third passage 35A is formed between the adjacent third fusion portion 35, and the bypass passage formed in the left and right directions to extend the air supply path It is preferable.

To this end, in the drawings of the present specification, it is possible to check the third fusion formed in a shape similar to the 'TT' and 'ㅠ' characters, which can also be modified in any form capable of performing the above-described function.

The third fusion portion 35 is formed in plural so as to be arranged in a zigzag up and down to extend the entire length of the third passage (35A) to block the flow of the supplied air in the reverse direction to improve the airtightness of the air filling portion 21 You can.

Subsequently, as the second embodiment of the present invention, as shown in FIGS. 8 to 12, when the air is filled, the endothelial 10 is expanded to correspond to the outer shape of the package object O to pressurize the package object O. It comprises a; fixing means formed by bonding a portion of the endothelial 10 and the outer shell 20 to be fixed.

Other configurations except for the fixing means are the same as in the first embodiment, and will be omitted for convenience of description.

As shown in FIG. 11, the air filling unit 21 of the present invention expands the inner skin 10 and the outer skin 20 in the inner and outer directions when filling the air, respectively.

At this time, the endothelial 10 is in close contact with the outer shape of the packaging object O1 in the receiving portion 12 (see FIG. 9) to be fixed by pressurizing the packaging object O1 through the internal pressure of the air filling part 21. It is preferable to prevent the flow of the package object O1 in the part 12 (refer to FIG. 2).

However, the outer shell 20 may also prevent the inner shell 10 from being closely adhered to the outer shape of the package object O1 by offsetting the inner expansion force of the endothelial 10 while expanding outward by air filling.

Especially in the case of the package object (O1) in the case of the package object (O1) that is easily damaged or damaged due to the flow of the package object in the receiving portion of the package bag (for example, a large number of eggs contained in an egg plate, fruit in a container similar to an egg plate, and a bulb) Due to the high degree of bending, the endothelial may be completely intimately packed to be packaged.

Therefore, when the endothelial 10 is in close contact with the package object O1 and cannot be firmly fixed, the package object O1 flows and collides with each other within the receiving portion 12 (see FIG. 9) when transporting the package. May occur.

Therefore, the present invention has introduced the front and rear fixing means of the package object (O1) to prevent the package object (O1) up and down, left and right flow.

11 illustrates a plurality of eggs contained in the egg plate, but this is for convenience of description and is not limited to those shown in the drawings of the present specification.

First, as shown in FIGS. 8 to 12, the fixing means includes one or more first adhesive parts 36 arranged in the center along the longitudinal direction of the air filling part 21.

The lengthwise direction of the air filling part 21 may vary depending on the shape and size of the package object O1 accommodated in the receiving part 12 (see FIG. 9), which can be seen in partial cross-sectional views of FIG. 11. As shown in the drawings of the present specification, for convenience of explanation, the individual packaging objects O1 arranged in two rows are representatively inserted into the accommodation portion 12 in the vertical direction, and thus the first adhesive portion is described. Reference numeral 36 has the form of a horizontal adhesive line orthogonal to the longitudinal direction of the air filling unit 21.

Although not shown in the drawing, the first adhesive part is not limited to the horizontal adhesive line, and is formed in the form of a vertical adhesive line or a diagonal adhesive line or a polygonal adhesive line or a circular adhesive line according to the package object O1 (P1). Can,

In particular, when formed in the form of a polygonal adhesive line or a circular adhesive line may be made to include a cutout that the endothelial and the outer skin is not bonded for the communication of the air filling unit.

In addition, it is obvious that the first adhesive part may be formed in a curved shape according to the shape of the package object as well as the straight form shown in the drawing.

In addition, the first adhesive part 36 is formed with one or more first adhesive parts 36 spaced apart from each other at predetermined intervals according to the size or length of the package object O1.

In addition, the first adhesive portion may be arranged between the individual package object (P1), but more preferably, as shown in [A] of Figure 5, the protruding end of the individual package object (P1) and More preferably, they are formed on the same line.

Through the first adhesive portion 36 formed on the same line as the protruding end of each package object P1, the air filling portion 21 of the present invention comprises an unfilled section of the air when the endothelial 10 is filled. The expansion pressure pressurized inwardly is increased,

By only partitioning and expanding the air filling portion 21 on the same line as the bent portion of the package object O1, the present invention provides that the endothelium 10 is formed to be in close contact with the outer surface of the package object O1, and thus the vertical flow of the package object O1 is increased. Can be prevented.

In addition, as the air filling portion 21 expands to the same width through the first adhesive portion 36, the present invention provides an air filling portion 21 having a uniform thickness to absorb shocks in all directions against external impacts. It is possible to reduce the volume of the entire package by not expanding the air filling portion 21 is biased.

Next, the fixing means of the present invention is characterized in that it comprises one or more second adhesive portion 37 which is arranged at both ends in the longitudinal direction of the air filling portion (21).

The second adhesive portion 37 is formed adjacent to both edge portions 38 of the inner shell 10 and the outer shell 20 to press the package object O1 of the receiving portion 12 inward from both sides. By fixing, the lateral flow of the package object O1 can be prevented.

As shown in FIG. 8, the present invention is formed at a position where the first adhesive portion 36 and the second adhesive portion 37 intersect each other, whereby the first and second adhesive portions 36 and 37 are formed. By preventing the flow through each other to prevent the omnidirectional flow of the package object (O1).

In addition, the second adhesive portion 37 may be formed adjacent to both edge portions 38 of the inner shell 10 and the outer shell 20 to reduce the volume of the package by excluding unnecessary air filling portions 21.

Naturally, the second adhesive part may be implemented in various forms according to the size or shape of the package object P1.

Therefore, in the present invention, the internal pressure of the air filling part 21 acts toward the inside of the receiving part 12 through the first adhesive part 36 and the second adhesive part 37, thereby preventing the air filling part 21. While ensuring a buffer function, it is possible to prevent the flow in the receiving portion 12 of the package object (O1).

In addition, the present invention has the effect of reducing the volume by preventing the external expansion of the outer shell more than necessary due to the first adhesive portion 36 and the second adhesive portion 37, which is the entire package using the buffer packaging bag according to the present invention The volume can be reduced and the transportation can be carried out very easily.

That is, in the case of the buffer packaging bag having no fixing means, the outer shell 20 is unnecessarily inflated to the outside, which attenuates the internal expansion force of the inner shell 10 so that the package object of the receiving unit 12 cannot be firmly fixed. As well as

While the outer shell 20 is unnecessarily expanded in a round shape as a whole, the entire volume is increased, which may cause inconvenience in transporting the package.

The present invention can ensure the internal expansion force of the endothelial 10 by introducing the fixing means and at the same time as shown in Figure 11, by reducing the volume of the entire package by partially expanding the outer shell 20 to have a uniform volume. There is,

In particular, the first adhesive part 36 or the second adhesive part 37 may be formed in a portion where the flow is relatively low and the buffer function is less required, thereby solving the problem of volume increase due to overexpansion.

Hereinafter will be described a method of manufacturing a buffer packaging bag according to the present invention.

The left and right ends are bonded to each other, and the eccentric, that is, the upper edge portion 39 of the endothelium 10 and the outer shell 20 extending from the input portion 11 are adhered to each other.

In addition, the step (2) is the second fusion unit 34 and the third fusion unit (34) after overlapping each component of the buffer bag according to the present invention, in particular the endothelial 10 and the inner sheet 30 35) at the same time,

Thereafter, after overlapping the outer shell, a separate heat-resistant member is placed on the input part 11 side in the folded state, and the first fusion line 22a and the second fusion line 22b and the four sides of the packaging bag, the left and right edges, and the One fusion unit 33 can be formed at the same time, depending on the case may be made in sequence depending on the working conditions, and the order is irrelevant.
