The lateral wall and the bottom of box body 4 have air cavity 41, and be provided with compressed gas in the air cavity 41, can guarantee that air cavity 41 has better buffering effect, can avoid external collision to cause the inside article of box body 4 structure to damage, integrate air cavity 41 in bilayer structure, need not additionally set up solitary gasbag, the structure is simpler, and can not occupy the inside space of box body 4 structure, can not cause the waste in space, and communicating pipe 42 establishes the lateral wall top of box body 4 and is sealing in the realization that is also more convenient.
Since the box body 4 will form a side wall and a bottom plate in the later forming process, the air cavities 41 formed in the first isolation region 111 need to be respectively arranged on the side wall and the bottom plate, so the first isolation region 111 includes a plurality of middle isolation strips 1111 and side isolation strips 1112, the middle isolation strips 1111 run through the two ends of the first outer sheet 1 in parallel, and the side isolation strips 1112 are obliquely arranged on the two sides of the middle isolation strips 1111. That is, the middle spacer 1111 may be transversely connected from one sidewall to the other sidewall via the bottom plate, and the side spacers 1112 are disposed on the other two sidewalls.
In this case, the air chamber 41 constituting the box body 4 is likely to be deformed by stretching during the plastic suction or molding, and therefore, the shapes of the middle barrier 1111 and the side barrier 1112 are preferably set to be wide at the top and narrow at the bottom, that is, the shapes of the middle barrier 1111 and the side barrier 1112 in the first isolation region 111 are preferably set to be wide at both ends and narrow at the middle.
Further, referring to fig. 1, as an embodiment of the method for producing the inflatable structure provided by the present invention, the first isolation layer 11 and the second isolation layer 21 each further include a third isolation region 113 for forming a connection portion connecting the air cavity 41 and the communicating tube 42, and the third isolation region 113 is disposed at a connection portion between the first isolation region 111 and the second isolation region 112. Specifically, the effect of third isolation region 113 is used for forming connecting portion, connecting portion set up the tip at air cavity 41, and connecting portion can connect the trachea, thereby guarantee when aerifing, gas can enter into the trachea, and give each air cavity 41 by the even transport of connecting portion of trachea one side, the gas velocity is faster and more convenient, can seal trachea and connecting portion pressure-sensitive closure simultaneously when sealing up the trachea, also can only carry out the pressfitting with connecting portion and seal, thereby make air cavity 41 form into independent sealed air cavity 41.
Further, referring to fig. 1, as a specific embodiment of the method for producing the inflatable structure provided by the present invention, the first isolation layer 11 and the second isolation layer 21 further include a fourth isolation region 114 for forming an inflation port connected to the air cavity 41 or the communicating tube 42, and the fourth isolation region 114 is located at an outer edge of the air cavity 41 or the communicating tube 42. The interior of the air chamber 41 can be inflated through an inflation port, i.e., one end of the connection port is disposed at the side of the air chamber 41 or the outer edge of the communication pipe 42, and the other end extends out of the first outer sheet 1.
Further, as a specific embodiment of the method for producing the inflatable structure provided by the present invention, the first isolation layer 11 and the second isolation layer 21 both use ink or texture layers. The printing ink layer and the texture layer can both play a good isolation effect, and can avoid bonding in modes such as high frequency, ultrasonic wave, heating or laser, so that the region isolated by the first isolation layer 11 can not be bonded, a relatively independent region is realized, and a plurality of independent and communicated air cavities 41 are formed during subsequent plastic uptake or mould pressing.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
