Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
155 words
A packing container comprising a double walled cylindrical body, said body including a pliable cylindrical member which is turned inside out and folded back at about the center of the length of said cylindrical member to form said double walled cylindrical body, a first binding cord threaded about the periphery of the lower end of the inner layer of said cylindrical body, a second binding cord threaded about the periphery of the lower end of the outer layer of said cylindrical body, said first and second binding cords being tied independently to substantially close the bottom of said cylindrical body, an annular member inserted in the folded back upper end of said cylindrical body and a plurality of circumferentially spaced apart closed loop shaped hanging cords encircling said annular member and projecting above the upper end of said cylindrical body, said annular member being used to substantially close the upper end of said cylindrical body.
Claim 2
Dependent Claim
155 words
A packing container comprising a double walled cylindrical body, said body including a pliable cylindrical member which is turned inside out and folded back at about the center of the length of said cylindrical member to form said double walled cylindrical body, a first binding cord threaded about the periphery of the lower end of the inner layer of said cylindrical body, a second binding cord threaded about the periphery of the lower end of the outer layer of said cylindrical body, said first and second binding cords being tied independently to substantially close the bottom of said cylindrical body, an annular member inserted in the folded back upper end of said cylindrical body and a plurality of circumferentially spaced apart closed loop shaped hanging cords encircling said annular member and projecting above the upper end of said cylindrical body, said annular member being used to substantially close the upper end of said cylindrical body.
Claim 3
Dependent Claim
23 words
The container according to claim 1 wherein said cylindrical member comprises a cloth of synthetic fibers coated with a film of synthetic resin.
Claim 4
Dependent Claim
57 words
The container according to claim 1 wherein said lower ends of said inner and outer layers are folded back to form circumferential loops and said first and second binding cords are threaded through said circumferential loops, the opposite ends of said first and second binding cords extending outwardly through openings formed through said inner and outer layers.
Claim 5
Dependent Claim
60 words
The container according to claim 1 wherein said annular member comprises a third binding cord contained in the folded back upper end of said cylindrical body, the opposite ends of said third binding cord extending outwardly through said cylindrical member, and wherein said cylindrical body is provided with a plurality of circumferentially spaced apart openings for accommodating said hanging cords.
Claim 6
Dependent Claim
44 words
The container according to claim 1 wherein a bottom lid is disposed in the bottom of said container, for closing the bottom opening thereof, and said bottom lid is secured in position by means of tapes passing about said first and second binding cords.
Claim 7
Dependent Claim
35 words
The container according to claim 1 wherein the diameter of the bottom opening formed by tieing said first binding cord is smaller than that of the bottom opening formed by tieing said second binding cord.
Claim 8
Dependent Claim
101 words
The container according to claim 6 wherein a cylindrical auxiliary bottom member is connected at its one end to the lower end of said outer layer near said second binding cord, and a third binding cord is threaded about the periphery of the opposite end of said auxiliary bottom member, said third binding cord substantially closing the bottom opening of said container when said third binding cord is tied, said auxiliary bottom member depending downwardly from said second binding cord when said third binding cord is untied, thus defining a contamination free discharge chute for the content contained in said container.
Claim 9
Dependent Claim
34 words
The container according to claim 7 wherein said auxiliary bottom member is turned upwardly around the bottom corner of said container to expose the bottom oppenings formed by said first and second binding cords.

The container according to claim 1 wherein the bottom opening formed by said second binding cord is smaller than that formed by said first binding cord and wherein said outer layer is connected to said inner layer at points close to said first binding cord so that when said second binding cord is untied the lower end of said outer layer depends downwardly to form a discharge chute.
Claim 17
Dependent Claim
22 words
The container according to claim 15 wherein an inner bag is disposed in said container, said inner bag having an openable bottom.
Claim 18
Dependent Claim
58 words
The container according to claim 15 wherein an annular sheet of pliable material is secured onto the inner surface of said outer layer at the lower end thereof, the lower side of said annular sheet extending beyond said second binding cord so as to substantially close the bottom of said container when said second bonding cord is tied.
Claim 19
Dependent Claim
50 words
The container according to claim 1 wherein the bottom opening formed by said second bonding cord is substantially equal to or a little smaller than that formed by said first binding cord and a bottom lid is interposed between said first and second binding cords to close said bottom openings.
Claim 20
Dependent Claim
