Definitions

  • the following disclosure relates to an air-filling type packaging material, and in particular, to an air-filling type packaging material that facilitates injection and sealing of air.
  • air-filling type packaging materials with improved shock-absorbing property are well-known.
  • synthetic films are applied to the outer surface thereof, and a plurality of air-cells filled with air are provided therein to improve their shock-absorbing property.
  • the present disclosure provides an air-filling type packaging material that does not require a high-quality check value and can be fabricated through a simple process.
  • Embodiments of the present invention provide air-filling type packaging materials including: a plurality of air-cells divided by adhesion of an upper sheet and a lower sheet and performing a shock-absorbing function; an air passage formed by adhesion of an upper sheet and a lower sheet such that external air flows into the air-cell; a communication passage formed by adhesion of the upper and lower sheets, and connected to the air passage at one side thereof and connected to the air-cell to discharge air at the other side thereof; and a sealing member disposed in the communication passage between a portion thereof connected to an air passage and a portion thereof connected to the air-cell to prevent air filled in the air-cell from flowing backward.
  • the communication passage may be disposed parallelly along a side surface of the air-cell.
  • the sealing member may be formed of a V-shaped sheet that is disposed between the upper sheet and the lower sheet, and faces the air passage at a sharp tip thereof and the air-cell at both ends thereof.
  • the sealing member may be disposed between the upper sheet and the lower sheet, and may adhere to the upper sheet and the lower sheet.
  • the air-filling type packaging material may further include an embossed sheet that allows the sealing member to more easily adhere to the upper sheet and the lower sheet.
  • the air-cell may have a bent shape.
  • the upper sheet and the lower sheet that form the air-cell may be partially adhered to each other such that the air-filling type packaging material is bent by blocking air from flowing into a portion of the air-cell.
  • the sealing member maintains the sealing of the respective air-cells, even when a portion of air-cells are damaged, other air-cells are not affected in their sealing characteristics, retaining their shock-absorbing function.
  • the air-filling type packaging material can be used not in a simple flat shape but in a cube-shape, its usability can increase and the time taken for packaging can be shortened.
  • An air-filling type packaging material may include an upper sheet 10 and a lower sheet 20.
  • the upper sheet 10 and the lower sheet 20 may adhere to each other to form partitions such as air-cells, air passages, and communication passages.
  • partitions such as air-cells, air passages, and communication passages.
  • FIG. 1 is a perspective view illustrating an air-filling type packaging material according to an embodiment of the present invention.
  • FIG. 2 is an exploded perspective view illustrating an air-filling type packaging material according to an embodiment of the present invention.
  • the air-filling type packaging material may include an air-cell 100, an air passage 200, and a communication passage 300.
  • the air-cell 100 may be divided by adhesion of the upper sheet 10 and the lower sheet 20 such that the air-cell 100 absorbs a shock from the outside.
  • the air passage 200 may allow air from the outside to pass through. More specifically, the air passage 200 may serve as an external air passage that allows air to flow into the air-cell 100.
  • the communication passage 300 may be connected to the air passage 200 at one side thereof (hereinafter, referred to as a communication passage air inlet 310), and may be connected to the air-cell 100 at the other side thereof (hereinafter, referred to as a communication passage air outlet 320).
  • the communication passage 300 may be disposed parallelly along the edge of the air-cell 100.
  • FIG. 3 is a cross-sectional view illustrating an air-filling type packaging material according to an embodiment of the present invention.
  • the air-filling packaging material may include an upper sheet 10 and a lower sheet 20, which adhere to each other to form an air-cell 10.
  • an air passage 200 may be disposed over an air-cell 100.
  • the air-cell 100 and the air passage 200 may be connected to each other through a communication passage 300.
  • external air received through the air passage 200 may flow into the communication passage 300 through a communication passage air inlet 310 of the communication passage 300.
  • External air flowing into the communication passage 300 may be discharged into the air-cell 100 through a communication passage air outlet 320 of the communication passage 300 connected to the air-cell 100, filling the air-cell 100 with air.
  • the air-filling type packaging material may include a sealing member 400.
  • the sealing member 400 of the air-filling type packaging material may facilitate air flow into the air-cell 100 and prevent air from leaking from the air-cell 100 to the outside.
  • the sealing member 400 may be formed inside the communication passage 300 such that air filled in the air-cell 100 does not leak.
  • the sealing member 400 may be formed of a synthetic resin sheet, and may be formed inside the communication passage 300.
  • the sealing member 400 may include a V-shaped sheet 410, whose sharp tip faces the air passage 200, and whose both ends face the air-cell 100.
  • the V-shaped sheet 410 may be disposed between the upper sheet 10 and the lower sheet 20, and may be adhered to the upper sheet 10 and the lower sheet 20 when the upper sheet 10 and the lower sheet 20 are adhered to each other.
  • FIG. 4 is a cross-sectional view taken along line A-A of FIG. 1 to illustrate an air-filling type packaging material according to an embodiment of the present invention.
  • External air flowing into the communication passage air outlet 320 may flows into the air-cell 100 to fill the air-cell 100.
  • air may flow backward into the V-shaped sheet 410 of the sealing member 400. Accordingly, both surfaces of the V-shaped sheet 410 facing the air-cell 100 may become more distant from each other, and may adhere to the inner sidewalls (i.e., the upper sheet 10 and the lower sheet 20 that form the communication passage 300) of the communication passage 300, respectively, preventing air from flowing backward to the outside.
  • the air-filling type packaging material may not require a separate operation that prevents air filled in the air-cell 100 from leaking to the outside.
  • the sealing member 400 may serve as a check valve.
  • the air-filling type packaging material may have a shock-absorbing function without a separate operation for retaining air filled therein.
  • the air-filling type packaging material may further include an embossed sheet 500.
  • the embossed sheet 500 may assist the sealing member 400 to effectively perform its function.
  • the embossed sheet 500 may be disposed in the V-shaped sheet 410 of the sealing member 400, and may assist the V-shaped sheet 410 to easily adhere to the upper sheet 10 and the lower sheet 20 when air flows backward.
  • air flowing backward may allow the V-shaped sheet 410 to smoothly adhere to the upper sheet 10 and the lower sheet 20.
  • FIG. 5 is a cross-sectional view illustrating an air-filling type packaging material according to another embodiment of the present invention.
  • the communication passage When a communication passage is linearly disposed along air-cells, and the air-cells are completely filled with air, the communication passage may be blocked.
  • the air-cells 100 and the communication passages 300 may be formed in a bent pattern, not in a linear pattern. In this case, even when the air-cells are filled with air, the air-filling type packaging material may maintain its straight and flat shape.
  • FIG. 7 is a cross-sectional view illustrating an air-filling type packaging material according to another embodiment of the present invention.
  • the air-filling type packaging material may be used while being folded in a cube-shape. Since it is not easy to fold a portion of the air-cell filled with air, other portions thereof that can be easily folded or bent may be adhered to the upper and lower sheets such that air is not filled therein.
  • the air-cell 100 may be easily folded at the portion W of the air-cell 100. Accordingly, the air-filling type packaging material can be utilized in various shapes such as box.
