Note that the cut line to be separated may be a completely separated line. In this case, the cut line is not stocked in the form of being wound in a roll, but is stocked in a stacked state.

  The airtight bag type cushioning material 1 is manufactured by using a bag making machine. This bag making machine uses a general-purpose machine that has been modified in advance so that it can be used for manufacturing the airtight bag type cushioning material 1. Here, since the bag making machine is a general purpose machine, the description thereof is omitted. The thermal bonding process of the longitudinal side edges 4, 5, 6, and 7 is performed in a state where the front side long film 2 and the back side long film 3 are moved, The thermal bonding step and the severing step except for the thermal bonding steps 5, 6 and 7 are performed in a state where the movement is stopped for a moment, thereby speeding up the production and producing a good product.

  The finished product 8 manufactured by performing the manufacturing process, that is, the sealed bag type cushioning material 1 is an inflatable / deflatable type sealed bag having an air supply / exhaust port 15 as shown in FIGS. The inward supply / discharge passage 19 and the closed portion 20 communicating with the supply / exhaust port 15 are formed by thermally bonding the vicinity of the supply / exhaust port 15 to provide the inward protruding portion 28, and the rim portion of the supply / discharge port 15 The outward projecting portion 29 is provided by extending outwardly, and both lateral edges of the outward projecting portion 29 are thermally bonded to form an outward supply / discharge passage 23 communicating with the supply / exhaust port 15. This is an inflatable / shrinkable cushioning material used as the air supply / exhaust pipe 30. Although the supply / exhaust pipe 30 is a short pipe in the drawing, it is possible to make a desired long supply / exhaust pipe by lengthening the heat bonding portions 24, 25 for forming the outward supply / discharge passage 23. It is.

  The long film 2 for the front side and the long film 3 for the back side include a base substrate made of ONY (stretched nylon), PET (polyethylene terephthalate) or OPP (stretched polypropylene), LLDPE (linear low density polyethylene), A laminate film formed by laminating a sealant substrate made of LDPE (low density polyethylene) or EVA (ethylene vinyl acetate) is used. This laminate film is expressed as a single unit on the drawing.

  The long film 2 for the front side and the long film 3 for the back side need only be heat-bondable, so other composite materials having a thermoplastic film layer on the bonding surface, single-leaf thermoplastic film are used. it can. Moreover, a tubular film can be employed in the present invention. In the case of manufacturing with this tubular film, it is possible to omit the thermal bonding process of the side edges 4, 5, 6, and 7 in the longitudinal direction, and the process can be simplified. In addition, the manufacturing method of the airtight bag type | mold shock absorbing material which concerns on Claim 10 also extends to the manufacturing method of the airtight bag type | mold buffering material by this tube-shaped film adoption.

  Further, the heat bonding locations 21 and 22 forming the inward supply / discharge passage 19 and the closing portion 20 are formed by tapering inner edges 32 and 33 of the heat bonding locations 21 and 22 so that the front end side becomes narrower and the heat bonding locations 21 and 22. The front end sides 34 and 35 of the head 22 are perpendicular to the inward supply / discharge path 19 and the outer corners of the front end sides 34 and 35 are arc-shaped with a small diameter (see FIG. 2). For this reason, when inflated, the tip portions 36 and 37 of the heat bonding portions 21 and 22 are pulled and crushed by the internal pressure, and at the same time the line portion 38 connecting the inner edge 32 and the inner edge 33 is bent. The air has not escaped. This was confirmed by an actual test.

  In the present invention, the inward supply / discharge passage 19 and the closing portion 20 are configured by, for example, thermal bonding portions 21 and 22 having various patterns as shown in FIGS. 12 (A), (B), (C), and (D). It can be implemented by. In addition, the part shown as a pointed drawing in the figure is a thermal bonding part. When these are both inflated, the tip portions 36 and 37 of the thermal bonding portions 21 and 22 are pulled away from each other by the internal pressure, and at the same time, the inner edge 32 and the inner edge 33 are connected. The portion 38 on the line is bent so that the air is difficult to escape. This was confirmed by an actual test. Although good results were obtained with patterns other than those described above, the disclosure thereof was omitted here.

  In fact, the sealed bag-type cushioning material 1 of the present invention composed of the above materials and the above-described configuration has a vertical side of 590 mm, a horizontal side of 460 mm, a width diameter of each thermal bonding portion of 10 mm, a maximum diameter of the supply / discharge port 15 of 24 mm, and a minimum diameter. A prototype of the airtight bag-type cushioning material 1 having a length of 14 mm, the length of the inward supply / discharge passage 19 of 20 mm, the length of the outward supply / discharge passage 23 of 40 mm, and a total thickness of 80 μ, filled with air, and expanded to the above-mentioned As shown in the figure, it was bent and closed.

  The airtight bag-type cushioning material 1 immediately leaves the air supply / exhaust passage 23, the supply / exhaust port 15, and the inward supply / exhaust passage 19 in a separated state using a fingertip, or when a straw is inserted. Start to leave.

Are packed in a packing box 42, and the sealed bag type cushioning material 1 is crushed on the upper surface of the packages 43. And the air supply / exhaust pipe 30 of the airtight bag type cushioning material 1 is protruded out of the packaging box through the drawer port 40. In this case, a part of the airtight bag type cushioning material 1 can be sandwiched between the inner surface of the side wall of the packing box 42 and the side surface of the luggage 43. If it does in this way, since a buffer material will enter also between a load and a box inner side, a buffer effect will become still better. Next, as shown in FIGS. 15 and 16, the packaging box 42 is closed and the closed state is not opened unless the lid opening operation is performed. In this way, air is supplied from the mouth of the air supply / exhaust pipe 30 protruding outside the packing box 42, and the air-tightness of the sealed bag type cushioning material 1 is expanded to stop the air supply. Then, the closing portion 20 is automatically closed by the internal pressure of the airtight bag type cushioning material 1 due to the stop of the air supply, and as a result, the luggage 43... Is held and fixed by the internal pressure of the expanded airtight bag type cushioning material 1. Is done. After this holding and fixing, as shown in FIGS. 18 and 19, the outer projecting portion of the air supply / exhaust pipe 30 is covered with a packaging adhesive tape 45 to complete. When performing the pasting work with the packing adhesive tape 45, as shown in FIG. 18, it is desirable to close the drawer port 40 together. It should be noted that the operation of pasting and closing the mouth of the air supply / exhaust pipe 30 by the last packing adhesive tape 45 can be performed by delivery for home delivery or others. In this way, leakage of inside air from the outward projecting portion of the air supply / exhaust pipe 30 is double-blocked by the sealing function by the closing portion 20 and the sealing function by the packing adhesive tape 45 and the delivery slip for delivery. And the leakage prevention of the inside air of the airtight bag type cushioning material 1 can be completed more completely. Note that a packing product such as a staple can be used instead of the packing adhesive tape 44 for maintaining the closed state of the packing box 42.

  The corrugated cardboard packaging box 42 has a structure that is not significantly different from that of a general-purpose one. Therefore, detailed description thereof will be omitted here, and different portions, that is, the outlet 40 of the air supply / exhaust pipe 30 will be described next. .

  As shown in FIG. 20, the outlet 40 cuts the opening / closing lid 41 along a cut line 50 including an upward inclined portion 47, a horizontal line portion 48, and a downward inclined portion 49, and the bottom end and the downward inclined portion of the upward inclined portion 47. A portion formed on the line connecting the hem side ends of the portion 49 is provided with a short straight cut line 51 that makes it easy to bend the portion on the line, and a portion surrounded by the upward inclined portion 47, the horizontal line portion 48, and the downward inclined portion 49 is formed. It is configured to function as the closing lid 52. The cut line 50 can be implemented by a perforated cut line that opens when it is pushed in or pulled out by a finger or the like, and the straight cut line 51 is a perforated cut line that can undulate the closure lid 52 with a finger or the like. Can be implemented. The drawing port 40 may be configured so as to allow the air supply / exhaust pipe 30 to be taken out, so that a short straight cut line, a short broken line cut line or a hole, a U-shaped cut line, It may be a curved cut line such as an arcuate cut line. Moreover, the structure which provides the drawer | drawing-out opening | mouth 40 by the method of opening with the tool and knife which have a sharp point in the use field may be sufficient as this invention. Furthermore, the drawer port 40 may be provided on the side wall, the bottom wall, and the bottom lid of the packing box 4.

  Further, the sealed bag type cushioning material 1 and the packing box 42 can be provided to the user in a separate state. Therefore, the user can manage the stock of the airtight bag type cushioning material 1 and the packing box 42 and use them arbitrarily.

  When the sealed bag type cushioning material 1 and the packaging box 42 are provided separately as described above, the sealed bag type cushioning material 1 is cut into a perforated cut line, a thin-walled cut line, or a tear line such as a tear line. Products can be provided in the form of rolls. Therefore, the sealed bag-type cushioning material 1 is convenient because it can be used by separating one by one as necessary. Moreover, it is preferable because it is easy to manage.

  Further, the user can obtain only the airtight bag type cushioning material 1 and can pack it using the packing box without the drawer opening 40 already owned. In this case, the packaging box without the drawer port 40 has some inconvenience that it is necessary to cut and provide the drawer port with a cutter knife or the like, but it can be used relatively easily.
