Since the heat-resistant material 18 is coated so that the two inner films 17 cannot be heat-sealed together to form the air inlet 12, in the embodiment of the present invention, the heat-resistant material 18 may be coated on both opposite surfaces of the two inner films 17.
Specifically, referring to fig. 2A to 2D, the heat-resistant region 171 extends from the left side edge to the right side edge of the inner film 17, and a part of the heat-resistant region 171 is located on the inflation passage 11. The second transverse heat-seal line 15b is located in the heat-resistant region 171.

The sleeper structure 13 is like a sleeper on a rail, and can enable the pressing wheel 31 to roll stably and disperse the pressure generated by the rolling of the pressing wheel 31. In addition, buffer air column 141 provides the gripping force required for puck 31 to roll during transport.
In the embodiment of the present invention, each air inlet 12 is specifically located between two adjacent upper pillow portions 131. The bottom end of each lower pillow 132 is flush with the transverse rolling line L, which means that the bottom end of the lower pillow 132 is flush with and flush with the rolling line L. The width range H of the rolling track 4 refers to the width of the rolling track 4 along the first direction, and the first direction is the direction in which the first transverse heat-sealing line 15a faces the second transverse heat-sealing line 15 b.
Wherein adjacent sleeper structures 13 are separated by heat sealing means (heat sealing zones). The sleeper structure 13 is provided to smoothly roll the pressing rollers 31 and to disperse the pressure generated when the pressing rollers 31 roll.

In one embodiment of the present invention, there are two air inlets 12 in the air chamber 14, so that there are two buffer section air columns 141, and one air chamber 14 only includes one main section air column 142.
In the embodiment shown in fig. 1, there are three gas inlets 12, three buffer section gas columns 141, and one main section gas column 142 is connected in sequence. Therefore, it can be understood that the number of the gas inlets 12 included in the gas chamber 14 affects the number of the buffer stage gas columns 141 and the size of the main stage gas column 142, and that the larger the number of the gas inlets 12 in the gas chamber 14, the larger the buffer stage gas columns 141 and the larger the main stage gas column 142. The present invention is not limited, as may be desired by the user and the associated practitioner.
In the embodiment of the present invention, the heat-resistant material 18 is coated in the heat-resistant region 171 in various ways. As shown in fig. 2A to 2D, the heat-resistant material 18 is continuously coated on the heat-resistant region 171 of one of the opposite surfaces of the two inner films 17 in parallel with the first transverse heat-seal line 15 a. If the heat-resistant material 18 is continuously coated in the heat-resistant region 171, an opening is formed first when the second transverse heat-sealing line 15b is formed by heat-sealing, and when the sleeper structure 13 is formed, the upper pillow portion 131 is located in the heat-resistant region 171, the lower pillow portion 132 is located outside the heat-resistant region 171, and the lower pillow portion 132 has a function of blocking the air flow and inflating, and the opening region is divided into the plurality of air inlets 12.
In another embodiment, the heat-resistant material 18 is coated on the heat-resistant region 171 of one of the opposite surfaces of the two inner films 17 at intervals, for example, the heat-resistant material 18 is coated on the inner film 17 in a dotted line shape or each heat-resistant material 18 is coated on the heat-resistant region 171 at intervals in a "T" shape. Thus, when the second transverse heat-seal line 15b is formed by heat-sealing, a plurality of air inlets 12 (at the positions of the heat-resistant material 18) are formed. However, the present invention is not limited.
In the present embodiment, each tie structure 13 further includes a cushioning node 133, the cushioning node 133 being formed on the upper pillow portion 131 and the lower pillow portion 132. The bumper node 133 serves to prevent the outer membrane 16 and the inner membrane 17 from collapsing during heat sealing to form the sleeper structure 13 and to prevent the inner membrane 17 from everting during inflation and adversely transporting the inflation. As shown in fig. 2A, each of the sleeper structures 13 has a substantially rectangular shape, and each of the sleeper structures 13 includes an upper pillow portion 131 and a lower pillow portion 132, the upper pillow portion 131 is connected to the lower pillow portion 132, the upper pillow portion 131 is located in the heat-resistant region 171, and the lower pillow portion 132 is located outside the heat-resistant region 171. In the embodiment shown in fig. 2B, the sleeper structure 13 is generally square.
In the above embodiments, the configuration of the sleeper structure 13 will affect the configuration of the buffer section air column 141, for example, in one embodiment, the buffer section air column 141 is connected to the main section air column 142 by a width-narrowing. In another embodiment, the buffer section gas column 141 is a narrow and wide continuous main section gas column 142. In other words, the present invention is not limited to the type of tie structure 13, and may be a geometric shape. In some embodiments, the shape of the block, the square, the triangle, the U-shape, the trapezoid, or the V-shape is at least one, as required by the manufacturer. In the embodiment shown in fig. 2C, the bottom of the sleeper structure 13 is rounded, or U-shaped. In one embodiment, the bottom of the sleeper structure 13 is generally V-shaped.
In addition, in the embodiment of the present invention, the air sealing body 1 further includes a plurality of heat sealing portions 20, the heat sealing portions are located in the main section air column and/or the buffer section air column, and the heat sealing portions are located between one of the two inner films and the outer film corresponding to the inner film, and the heat sealing portions are at least one of heat sealing points and heat sealing lines.
The heat seal is located in the cushion section gas column in fig. 2A, the main section gas column in fig. 2B, and the cushion section gas column and the main section gas column in fig. 2C. Wherein each heat seal 20 comprises a heat seal point, a heat seal line, or a combination of at least two. The heat sealing portion 20 is configured as shown in fig. 2C, and may be formed by combining one of the inner films 17 with the outer film 16, and when the inner film 17 is inflated, the un-attached inner film 17 will be attached to the attached inner film 17 and outer film 16 after the main section air column 142 is expanded, so as to prevent the gas from flowing back.
Referring to fig. 2A, in the embodiment of the present invention, the longitudinal heat-sealing lines 19 include a first longitudinal heat-sealing line and a second longitudinal heat-sealing line, and a longitudinal tearing line 193 is disposed between the first longitudinal heat-sealing line and the second longitudinal heat-sealing line. In this way, the manufacturer or user can tear the desired (e.g., the inflated portion of the air sealing body 1) air sealing body 1 by the longitudinal tear line 193 according to the requirement, and is not limited to inflating the entire air sealing body 1 and then cutting the same.
Please refer to fig. 3, which is a schematic view illustrating a usage status of an embodiment of the air sealing body 1. Because the air sealing body 1 needs to be inflated by the processing machine 3 for use, the processing machine 3 comprises an inflating rod 32 and a plurality of pressing wheels 31, the inflating rod 32 inflates the air sealing body 1, and each pressing wheel 31 respectively presses the rolling track 4 of the air sealing body 1 to convey the air sealing body 1.
Since the airtight body 1 includes the sleeper structures 13, each sleeper structure 13 includes the upper pillow portion 131 and the lower pillow portion 132, the upper pillow portion 131 is located in the heat-resistant region 171, the lower pillow portion 132 is located outside the heat-resistant region 171, and the bottom end of each lower pillow portion 132 is aligned with the transverse rolling line L, and the width range H of the rolling track 4 at least includes the inflation channel 11 to the rolling line L. The sleeper structure 13 is like a sleeper on a rail, and can enable the pressing wheel 31 to roll stably and disperse the pressure generated by the rolling of the pressing wheel 31. In addition, buffer air column 141 provides the gripping force required for puck 31 to roll during transport.
Referring to fig. 2C and 2D, in this embodiment, the second transverse heat-sealing line 15B forms a curved structure at each air inlet 12, further affecting the shape of the buffer section air column 141, and protrudes toward the first transverse heat-sealing line 15a at a position opposite to the air inlet 12 after expansion, unlike the buffer section air column 141 in the embodiment of fig. 2A and 2B. By the arrangement mode, the tension, the holding force and the grinding force for conveying the pressing wheel 31 in the processing machine table 3 can be increased.
In other words, the second transverse heat-sealing line 15b may be a straight line, or may have a curved (or bent) structure, as shown in fig. 2C and 2D.
In the embodiment of the present invention, the width range H of the rolling track 4 further includes the width of the first transverse heat-sealing line 15 a. The width range H of the rolling track 4 depends on the arrangement of the pressing wheel 31 in the processing machine 3, and the invention is not limited thereto.
In the embodiment of the present invention, as shown in fig. 2A to 2C, the top edge line of the inner film 17 (the top edge line is the edge line of the inner film 17 away from the first transverse heat seal line 15 a) is flush with the top edge line of the outer film, that is, the height of the inner film 17 (the height in the direction perpendicular to the length direction of the first transverse heat seal line 15 a) is equal to the height of the outer film 16. In fig. 2D, the tip edge line of the inner film 17 is lower than the tip edge line of the outer film 16, that is, the height of the inner film 17 is lower than the height of the outer film 16.
Without the design of the sleeper structure 13 and the buffer section air column 141, the air-filling rod 32 directly fills the main section air column 142, and once the main section air column 142 becomes larger in volume and is formed, the pressing wheel 31 cannot smoothly support the air sealing body 1, and at this time, the air sealing body 1 is displaced. The air sealing body 1 of the embodiment of the invention is provided with a sleeper structure 13 and a buffer section air column 141, the sleeper structure 13 can enable the pressure wheel 31 to be stably conveyed in the inflating process, and the pressure in rolling is dispersed; buffer section air column 141 provides the tension, grasping force and grinding force of pressure roller 31, so that pressure roller 31 rolls smoothly, and thus air sealing body 1 does not separate from the inflated conveying track.
According to the air sealing body 1 with the buffering function provided by the embodiment of the invention, the sleeper structure 13 and the buffer section air columns 141 are provided, so that the rolling and the transmission of the pressing wheel 31 are facilitated, the sleeper structure 13 helps the pressing wheel 31 to stably transmit and disperse pressure, and the pressing wheel 31 does not directly contact with the main section air columns 142, so that the pressing wheel 31 cannot smoothly roll and transmit the air sealing body 1 due to the fact that the volume of the main section air columns 142 is increased when the main section air columns 142 are inflated, the air sealing body 1 cannot be displaced, and inflated and uninflated parts of the air sealing body can be smoothly transmitted.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
