Liquid container

Abstract

A liquid container includes a container member including two layers of sheets at least, a spout and an elastic body provided on the container member. The two layers of sheets are flexible and disposed opposite one another. The container member has a sealed space. The elastic body is capable of elastic recovery from a first state in which the elastic body is extended along a direction of an axial line of the spout to a second state in which the elastic body is in a coiled shape as seen in an intersecting direction, which intersects the direction of the axial line and which is generally parallel to the two layers of sheets. A width of the elastic body on a virtual straight line is less than a width of the sealed space on the virtual straight line, which extends in the intersecting direction.

What is claimed is: 
     
         1 . A liquid container, comprising:
 a container member including two layers of sheets at least, the two layers of sheets being flexible and disposed opposite one another, the container member having a sealed space scaled in a portion sandwiched between the two layers of sheets;   a spout having a hollow portion communicatively connected to the sealed space; and   an elastic body provided on the container member, the elastic body being capable of elastic recovery from a first state in which the elastic body is extended along a direction of an axial line of the spout to a second state in which the elastic body is in a coiled shape as seen in an intersecting direction, the intersecting direction intersecting the direction of the axial line and being generally parallel to the two layers of sheets, a width of the elastic body on a virtual straight line being less than a width of the sealed space on the virtual straight line, the virtual straight line extending in the intersecting direction.   
     
     
         2 . The liquid container according to  claim 1 ,
 wherein the elastic body is provided on one of the two layers of sheets, in a central portion of the sealed space in the intersecting direction.   
     
     
         3 . The liquid container according to  claim 1 ,
 wherein the elastic body is provided in a portion of one of the two layers of sheets, the portion being configured to contact a horizontal surface when a liquid is contained in the sealed space and the liquid container is placed on the horizontal surface in an orientation in which one of the two layers of sheets is disposed above the other.   
     
     
         4 . A liquid container, comprising:
 a container member including two layers of sheets at least, the two layers of sheets being flexible and disposed opposite one another, the container member having a sealed space sealed in a portion sandwiched between the two layers of sheets;   a joined portion where the two layers of sheets are joined to one another;   a spout having a hollow portion communicatively connected to the sealed space; and   an elastic body provided on the container member, the elastic body being capable of elastic recovery from a first state in which the elastic body is extended along a direction of an axial line of the spout to a second state in which the elastic body is in a coiled shape as seen in an intersecting direction, the intersecting direction intersecting the direction of the axial line and being generally parallel to the two layers of sheets, the elastic body being provided in a part of the joined portion extending along the direction of the axial line.   
     
     
         5 . The liquid container according to  claim 4 ,
 wherein a width of the elastic body on a virtual straight line is less than a width of the scaled space on the virtual straight line, the virtual straight line extending in the intersecting direction.   
     
     
         6 . The liquid container according to  claim 5 ,
 wherein the two layers of sheets are formed by two sheets disposed opposite one another, and   wherein the joined portion is a portion where peripheral edges of the two sheets are joined to one another.   
     
     
         7 . The liquid container according to  claim 6 , wherein
 the elastic body is sandwiched between the two sheets in the joined portion.   
     
     
         8 . The liquid container according to  claim 5 ,
 wherein a width of the elastic body on the virtual straight line is less than a width of the joined portion, on the virtual straight line, in which the elastic body is provided.   
     
     
         9 . A liquid container, comprising:
 a container member including two layers of sheets at least, the two layers of sheets being flexible and disposed opposite one another, the container member having a sealed space sealed in a portion sandwiched between the two layers of sheets;   a spout having a hollow portion communicatively connected to the sealed space; and   a pouch portion provided on the container member, the pouch portion being in a shape of a pouch and extending along a direction of an axial line of the spout, a width of the pouch portion on a virtual straight line being less than a width of the scaled space on the virtual straight line, the virtual straight line extending in an intersecting direction, the intersecting direction intersecting the direction of the axial line and being generally parallel to the two layers of sheets.   
     
     
         10 . The liquid container, according to  claim 9 , further comprising:
 a joined portion where the two layers of sheets are joined to one another,   wherein the pouch portion is provided in a part of the joined portion extending along the direction of the axial line.   
     
     
         11 . The liquid container according to  claim 10 ,
 wherein the two layers of sheets are formed by two sheets disposed opposite one another, and   wherein the joined portion is a portion where peripheral edges of the two sheets are joined to one another.   
     
     
         12 . The liquid container according to  claim 11 , wherein
 the pouch portion is formed in a portion sandwiched between the two sheets in the joined portion.   
     
     
         13 . The liquid container according to  claim 9 ,
 wherein the pouch portion is provided on one of the two layers of sheets, in a central portion of the sealed space in the intersecting direction.   
     
     
         14 . The liquid container according to  claim 10 ,
 wherein a width of the pouch portion on the virtual straight line is less than a width of the joined portion, on the virtual straight line, in which the pouch portion is provided.   
     
     
         15 . The liquid container according to  claim 9 ,
 wherein the pouch portion is provided in a portion of one of the two layers of sheets, the portion being configured to contact a horizontal surface when a liquid is contained in the sealed space and the liquid container is placed on the horizontal surface in an orientation in which one of the two layers of sheets is disposed above the other.
