Abstract:
1. A multi-sectional clamping type air enclosure, comprising: two outer films stacked together; two inner films stacked together and having two faces and positioned and enclosed between the two outer films; two parallel hot sealing lines positioned on one end of the two outer films for adhering the two outer films together, a first one of the hot sealing lines adhering the two outer films together and a second one adhering both the two outer films and the two inner films together; an air filling passageway positioned between the two hot sealing lines and including a space formed between the two outer films; a first air cylinder body including an air storable space defined between the two outer films at the opposite side of the second hot sealing line from the air filling passage and comprising a plurality of first air cylinders, wherein one end of the two inner films is disposed in the air filling passageway and another end is positioned in the first air cylinder body; a plurality of air inlets formed between the air filling passage and the first air cylinder body through the second one of the hot sealing lines, respectively in communication with the plurality of first air cylinders; a first hot sealing point and a second hot sealing point positioned in the air filling passageway and between the two hot sealing lines, the first hot sealing point lying between one of the two outer films and one of the two inner films which are adhered to each other at the first hot sealing point, the second hot sealing point lying between the other of the two outer films and the other of the two inner films which are adhered to each other at the second hot sealing point, wherein air entering said air filling passageway expands said air filling passageway, allowing the two outer films to be pushed apart outward from each other to thereby drive said inner films, that are not fixed to each other, to be pulled apart outward via said first hot sealing point and via said second hot sealing point; at least one second air cylinder body including an air storable space defined between the two outer films and communicating with the first air cylinder body, the second air cylinder body comprising: a plurality of second main air cylinders; a plurality of second side air cylinders; and a plurality of second auxiliary air cylinders disposed side by side with the second side air cylinders at two sides of the plurality of second main air cylinders, each of the second side air cylinders communicating with at least one second auxiliary air cylinder, a first of the second auxiliary air cylinders being farther away from the plurality of second main air cylinders than a second of the second auxiliary air cylinders, the first of the second auxiliary air cylinders having a length greater than a length of the second of the second auxiliary air cylinders that is closer to the plurality of second main air cylinders; a third air cylinder body communicating with the second air cylinder body and comprising: a plurality of third main air cylinders; and a plurality of third side air cylinders; and a plurality of third auxiliary air cylinders disposed side by side with the third side air cylinders at two sides of the plurality of third main air cylinders, each of the third side air cylinders communicating with at least one third auxiliary air cylinder, a first of the third auxiliary air cylinders being farther away from the plurality of third main air cylinders than a second of the third auxiliary air cylinders, the first of the third auxiliary air cylinders having a length greater than a length of the second of the third auxiliary air cylinders; at least one fourth air cylinder body communicating with the third air cylinder body and comprising: a plurality of fourth main air cylinders; a plurality of fourth side air cylinders; and a plurality of fourth auxiliary air cylinders disposed side by side with the fourth side air cylinders at two sides of the plurality of fourth main air cylinders, each of the fourth side air cylinders in communication with at least one fourth auxiliary air cylinder, a first of the fourth auxiliary air cylinders being farther away from the plurality of fourth main air cylinders than a second of the fourth auxiliary air cylinders, the first of the fourth auxiliary air cylinders having a length greater than a length of the second of the fourth auxiliary air cylinders that is closer to the plurality of fourth main air cylinders; and a plurality of air entering passageways connected to the air filling passageway and the first air cylinder body, and formed on one or more of the faces of the inner films, the air enters to expand the air filling passageway, the two faces of the inner films being adapted to be driven to pull apart outward at the hot sealing points to open the air entering passageway, causing the air in the air filling passageway to enter the first air cylinder body through the air entering passageways to allow the first air cylinder body and the second cylinder body to be filled with air and expanded, the air entering the first air cylinder body and then compressing at least one of the inner films to cover the air entering passageways to shield the first air cylinder body and the second air cylinder body, one or more of the auxiliary air cylinders being bent toward one or more of the main air cylinders to cause one or more of the side air cylinders to be approximately perpendicular to the one or more main air cylinders to clamp an article after the second air cylinder body and the fourth air cylinder body are bent toward the third air cylinder body.
