Liquid container

Abstract

A liquid container including a container body with a thermal insulation function for storing a liquid, a lid member detachably attached to an upper end opening of the container body, and a carrying handle rotatably and detachably attached to an upper part of the container body, wherein a handle attaching part of the carrying handle is engageable with a handle mounting part of the container body to prevent the carrying handle from being detached from the container body when the carrying handle is used to hang the liquid container, and the handle attaching part of the carrying handle is releasable from the handle mounting part of the container body to permit the carrying handle to be detached from the container body when the carrying handle is not used to hang the liquid container.

1 . A liquid container, comprising a container body with a thermal insulation function for storing a liquid; a lid member detachably attached to an upper end opening of said container body; and a carrying handle rotatably and detachably attached to an upper part of said container body, 
 wherein a part of a handle attaching part of said carrying handle is engageable with a part of a handle mounting part of said container body to prevent said carrying handle from being detached from said container body when said carrying handle is used to hang said liquid container, and said part of said handle attaching part of said carrying handle is releasable from said part of said handle mounting part of said container body to permit said carrying handle to be detached from said container body when said carrying handle is not used to hang said liquid container.    
   
   
       2 . A liquid container as set forth in  claim 1 , further comprising a plurality of component parts detachably attached to said container body in fixed positions, said part of said handle attaching part of said carrying handle being engaged with said part of said handle mounting part of said container body to prevent said carrying handle from being detached from said container body when all of said component parts have been attached to said container body in said fixed position.  
   
   
       3 . A liquid container as set forth in  claim 2 , wherein said part of said handle attaching part of said carrying handle is releasable from said part of said handle mounting part of said container body to permit said carrying handle to be detached from said container body when at least one predetermined component part among said plurality of component parts has been displaced or detached from its fixed position.  
   
   
       4 . A liquid container as set forth in  claim 1 , further comprising a liquid discharge passage for directing said liquid stored in said container body to the outside of said container body, wherein a valve unit having a liquid discharge port as an outlet to the outside of said passage and a cutoff valve for stopping a flow of liquid from said container body to said liquid discharge port is detachably installed in said liquid discharge passage.  
   
   
       5 . A liquid container as set forth in  claim 1 , further comprising a liquid level pipe for indicating the amount of liquid in said container body; and first and second packing seals attached to upper and lower ends of said liquid level pipe, wherein adhesion preventing means are provided on both upper and lower ends of said liquid level pipe where said first and second packing seals are attached for preventing breakage of said upper and lower ends of sail liquid level pipe and adhesion of said upper and lower ends of sail liquid level pipe to said first and second packing seals, and wherein said liquid level pipe can be detached from said body case with said first and said second packing being left on the container body.  
   
   
       6 . A liquid container as set force in  claim 5 , wherein each of said first and second packing seals has a plurality of annular projections at axially spaced points on a surface thereof to be in contact with said liquid level pipe.  
   
   
       7 . A liquid container, comprising a container body with a thermal insulation function for storing liquid; and a liquid discharge passage for directing said liquid stored in said container body to the outside of said container body, 
 wherein a valve unit having a liquid discharge port as an outlet to the outside of said passage and a cutoff valve for stopping a flow of liquid from said container body to said liquid discharge port is detachably installed in said liquid discharge passage.    
   
   
       8 . A liquid container, comprising a container body with a thermal insulation function for storing liquid; a liquid level pipe for indicating the amount of liquid in said container body; and first and second packing seals attached to upper and lower ends of said liquid level pipe, 
 wherein adhesion preventing means are provided on both upper and lower ends of said liquid level pipe where said first and second packing seals are attached for preventing breakage of said upper and lower ends of sail liquid level pipe and adhesion of said upper and lower ends of sail liquid level pipe to said first and second packing seals, and    wherein said liquid level pipe can be detached from said body case with said first and said second packing being left on the container body.    
   
   
       9 . A liquid container as set force in  claim 8 , wherein each of said first and second packing seals has a plurality of annular projections at axially spaced points on a surface thereof to be in contact with said liquid level pipe.
