Transporting bag structure

Abstract

A transporting bag structure is provided, which includes: a bag body, including an opening and an accommodating space; and a channel pipe, connected the accommodating space and an outside space. A first end of the channel pipe is exposed out of the bag body. A second end of the channel pipe is located inside the accommodating space. A gas and a fluid flow into the accommodating space to form a gas layer and a fluid layer. The channel pipe penetrates the gas layer and enables the second end to be immersed in the fluid layer. The channel pipe is closed by being pressed in a segmented manner due to pressure differentials of the layers, so that the gas of the gas layer is not able to flow back out of the accommodating space via the channel pipe, and the fluid of the fluid layer is unable to flow back.

1 . A transporting bag structure, comprising:
 a bag body, comprising an opening and an accommodating space; and   a channel pipe, located at the opening and connecting the accommodating space and an outside space, wherein the channel pipe comprises a first end and a second end, the first end is exposed out of the bag body and located at the outside space, the second end is located inside the accommodating space, a gas and a fluid flow into the accommodating space via the channel pipe to form a gas layer and a fluid layer, and the channel pipe penetrates the gas layer and enables the second end to be immersed in the fluid layer, so that the gas of the gas layer is not able to flow back out of the accommodating space via the channel, and the fluid of the fluid layer is not able to flow back out of the gas layer.   
     
     
         2 . The transporting bag structure according to  claim 1 , wherein the bag body is formed with various bag shapes by binding at least one first plastic membrane through heat-sealing. 
     
     
         3 . The transporting bag structure according to  claim 2 , wherein a heat-resisting material is coated on a part at the heat-sealed binding of the bag body, and the part is not bound during the heat-sealing to form the opening. 
     
     
         4 . The transporting bag structure according to  claim 1 , wherein the channel pipe is formed of an upper second plastic membrane layer and a lower second plastic membrane layer. 
     
     
         5 . The transporting bag structure according to  claim 4 , wherein the channel pipe enables the second plastic membranes to be tightly attached to each other to form a segmented channel lock as the gas and the fluid stored in the bag body is incapable of exchange due to different densities and specific gravities and different internal pressures are generated in two spaces having different densities and specific gravities. 
     
     
         6 . The transporting bag structure according to  claim 1 , wherein the channel pipe is bound to the opening through heat-sealing, and an inside surface of the channel pipe is coated with a heat-resisting material in advance, so that during the heat-sealing, the opening and the channel pipe are bound through the heat-sealing, and the inside surface of the channel is not bound and connects the accommodating space and the outside space. 
     
     
         7 . The transporting bag structure according to  claim 1 , wherein the second end of the channel pipe further comprises a weight element, used to enable the second end of the channel pipe to be immersed in the fluid layer. 
     
     
         8 . The transporting bag structure according to  claim 1 , wherein the bag body further comprises an outlet portion, used to discharge the fluid.
