[0021]According to the packing bag for transportation of claim 1, the packing bag for transportation includes: the body having the opening; and the openable and closable sealing part for sealing the opening, the body including: the two packing material sheets each formed of the thermoplastic synthetic resin film; the absorbing material sandwiched between the two packing material sheets, the absorbing material being obtained in such a manner that the synthetic fiber drawn into a fibrous form is subjected to the hydrophilic treatment and then woven into cloth; and the sides sandwiching the absorbing material, which are heat-sealed at the portions excluding the opening. Accordingly, when heat-sealing sides of the two packing material sheets which sandwich the absorbing material therebetween, the synthetic fiber forming the absorbing material is fused to fill pores of fibers, to thereby be welded to the packing material sheets. As a result, heat-sealed parts are sealed so as to prevent penetration of liquid. In a case where liquid leaks in the body, the liquid absorbed by the absorbing material does not seep through the heat-sealed parts out of the body.
[0022]Further, regarding the absorbing material, the synthetic fiber drawn into a fibrous form is subjected to the hydrophilic treatment, and hence the absorbing material attracts the liquid leaking in the body, with the result that the liquid can be absorbed and kept in the pores of fibers of the absorbing material.
[0023]According to the packing bag for transportation of claim 2, the synthetic fiber subjected to the hydrophilic treatment according to claim 1 is obtained in such a manner that the thermoplastic resin subjected to the hydrophilic treatment is laminated on the surface of the synthetic fiber, and hence the thermoplastic resin laminated on the surface of the synthetic fiber attracts the liquid leaking in the body, with the result that the liquid can be absorbed and kept in the pores of fibers of the absorbing material.
[0024]According to the packing bag for transportation of claim 3, the synthetic resin drawn into the fibrous form according to claim 1 or 2 includes a synthetic resin having a hydrophilic group, and hence the synthetic resin more effectively attracts the liquid leaking in the body, with the result that the liquid can be absorbed and kept in the pores of fibers of the absorbing material.
[0025]According to the packing bag for transportation of claim 4, the sealing part for sealing the opening of the body according to any one of claims 1, 2, and 3 includes a slide zipper or a seal zipper, and hence operations of opening and sealing are facilitated. As a result, when opening the opening of the packing bag, dangerous tools such as scissors and a knife are not needed.
[0026]According to the packing bag for transportation of claim 5, the thermoplastic synthetic resin film forming each of the packing material sheets according to any one of claims 1, 2, 3, and 4 is transparent, and hence a state of an object contained in the body can be recognized from an outside of the body. In a state in which the body is still sealed, for example, a label or a bar code attached to the object contained in the body can be recognized from the outside of the body.
Problems solved by technology
In a case of transporting a container containing liquid, the liquid may spill out due to a breakage of the container, looseness of a cap, or the like, which may stain other articles of transport.
This manufacture of this packing bag inevitably requires much time and high cost, and hence there has been a expectation for simplification of the packing bag.
Therefore, manufacture of the envelope requires much time and effort, and hence the envelope is not necessarily satisfactory in terms of cost.
The transportation of the container requires that the container be sealed in a packing bag which is fabricated so as to prevent a leakage of liquid, but the envelope as proposed above is disadvantageous in terms of cost.
Accordingly, there is a problem of more inexpensive packing bag.
As a result, the packing bag is inadequate to prevent a leakage of liquid.
However, the fibrous structure made of the thermoplastic resin hardly absorbs liquid, and hence is inadequate as the absorbing material.
However, in a case where a content of the thermoplastic resin powder is low, when the packing materials each formed of the synthetic resin film are heat-sealed together, the pores of fibers of the fibrous structure of the absorbing material are not completely filled with the fused thermoplastic resin, and the capillarity action occurs at the heat-sealed parts, with the result that the liquid contained in the body seeps out.
However, the pores of fibers of the fibrous structure of the absorbing material are filled with the thermoplastic resin powder, and hence the pores of fibers of the fibrous structure are reduced, which causes a problem in that an amount of absorbed liquid is reduced.
However, this packing bag requires much time and effort for positioning the absorbing material.
Accordingly, this packing bag is inadequate for mass production, and needs high cost.

Description
TECHNICAL FIELD[0001]The present invention relates to a packing bag for transportation, which is used for transporting articles such as a container containing liquid, and food containing an exudative fluid.BACKGROUND ART[0002]In a case of transporting a container containing liquid, the liquid may spill out due to a breakage of the container, looseness of a cap, or the like, which may stain other articles of transport. Conventionally, in order to prevent this problem, the container is covered with an absorbing material for absorbing the spilled liquid, and the covered container is put into a packing bag. Then, double packing is performed by putting the container into another packing bag, or the container is put into, instead of the another packing bag, a tough container capable of preventing a breakage. This manufacture of this packing bag inevitably requires much time and high cost, and hence there has been a expectation for simplification of the packing bag.[0003]In order to meet t...
