An air-sealed body capable of automatically opening an air valve is provided. First, the two inner films are laminated between two outer films. An air passage and a plurality of air columns are formed through joining by means of heat-sealing. Air inlets are formed by heat-sealing in the two inner films at the places where the heat-resisting material is coated, and a plurality of heat-sealed blocks is formed through joining by means of heat-sealing at the sides of the air inlets. When air is filled in, the two outer films of the air passage are pulled open outward in a longitudinal direction, the air passage contracts in a lateral direction due to a drop height of the heat-sealed blocks. The two inner films are squeezed by the heat-sealed blocks to be pulled open outward in the longitudinal direction to open the air inlet.
An air-sealed body capable of automatically opening an air valve, comprising:
The air-sealed body capable of automatically opening an air valve according to claim 6, wherein the air-guiding portion is located at the air passage.
The air-sealed body capable of automatically opening an air valve according to claim 6, wherein each heat-sealed block comprises a positioning portion connected to the air-guiding portion, and the air inlets are located at the sides of the positioning portion.
The air-sealed body capable of automatically opening an air valve according to claim 8, wherein the positioning portion is joined to the first sides of the two inner films and the two outer films.
The air-sealed body capable of automatically opening an air valve according to claim 8, wherein the air-guiding portion is joined to the first sides of the two inner films and the two outer films.
A method for manufacturing an air-sealed body capable of automatically opening an air valve, comprising:
The method for manufacturing an air-sealed body capable of automatically opening an air valve according to claim 13, wherein the heat-resisting material is coated between the two inner films at a length equal to that of the first side.
The method for manufacturing an air-sealed body capable of automatically opening an air valve according to claim 13, wherein the heat-resisting material is coated between the two inner films at intervals.
The method for manufacturing an air-sealed body capable of automatically opening an air valve according to claim 18, wherein the air-guiding portion is located at the air passage.
The method for manufacturing an air-sealed body capable of automatically opening an air valve according to claim 19, wherein each heat-sealed block comprises a positioning portion connected to the air-guiding portion, and the air inlets are located at the sides of the positioning portion.
The method for manufacturing an air-sealed body capable of automatically opening an air valve according to claim 20, wherein the positioning portion is joined to the first sides of the two inner films and the two outer films.
The method for manufacturing an air-sealed body capable of automatically opening an air valve according to claim 20, wherein the air-guiding portion is joined to the first sides of the two inner films and the two outer films.
