Cushion panel with different transparency and bag having the same

Abstract

Described herein are a cushion panel with different transparency which exhibits high impact-absorbing capability and is superior in design, and a bag having the cushion panel, the cushion panel including a transparent outer film, a translucent inner film for creating a closed space together with the outer film, and a plurality of cushion cells which are provided by adhering the outer film to the inner film along lines, which become transparent by thermal adhering between the outer film and the inner film.

1 . A cushion panel with different transparency, comprising:
 a transparent outer film having a thickness of about 0.3-0.8 mm;   a translucent inner film having a thickness of about 0.3-0.8 mm for creating a closed space, together with the outer film, by thermally adhering edges of the inner film to the outer film; and   a plurality of cushion cells provided by thermally adhering the outer film to the inner film along inner lines, the cushion cells partitioning the closed space into several spaces;   wherein a passage is formed to allow neighboring cushion cells to communicate with each other, and   wherein a width of the inner adhering lines is 3 mm-6 mm and the inner adhering lines become transparent a sufficient amount to allow an item positioned inside the inner film to be seen from outside the outer film, and transparency of the inner adhering lines is higher than that of other parts of the cushion panel.   
     
     
         2 . The cushion panel with different transparency as set forth in  claim 1 , wherein each of the cushion cells has a polygonal structure which has at a vertex thereof the passage. 
     
     
         3 . The cushion panel with different transparency as set forth in  claim 1 , wherein the passage has a width of from 3 to 6 mm. 
     
     
         4 . The cushion panel with different transparency as set forth in  claim 1 , wherein each of the cushion cells is filled with air, and the closed space is air-tightly sealed. 
     
     
         5 . The cushion panel with different transparency as set forth in  claim 1 , wherein an outer adhering line is formed along edges of the outer and inner films and a corner of the outer adhering line is rounded. 
     
     
         6 . The cushion panel with different transparency as set forth in  claim 1 , wherein the inner film has a lower friction coefficient than the outer film. 
     
     
         7 . The cushion panel with different transparency as set forth in  claim 6 , wherein the inner film has on a surface thereof a pattern so that the inner film is less transparent than that of the outer film. 
     
     
         8 . The cushion panel with different transparency as set forth in  claim 1 ,
 wherein the transparent outer film and the translucent inner film are formed from thermoplastic polyurethane (TPU) resin.   
     
     
         9 . A bag with different transparency, comprising:
 upper and lower cushion panels, at least one of which is defined in  claim 1 ;   a holding space created by coupling edges of the upper and lower panels to each other;   a mouth communicating with the holding space; and   a fastener to close and open the mouth,   wherein a color and/or shape of an item contained in the holding space can be more clearly identified from outside of the bag through the inner adhering lines formed in the cushion panel than through other parts of the cushion panel.
