Description

  The present invention relates to a caster-equipped polycontainer or polycontainer transport caster that stores and transports kerosene using a standard JIS or other standard polytank as it is.

  There is a plastic container as a container for storing and transporting kerosene and drinking water. These plastic containers are commercially available in 18 liter or 20 liter sizes. For example, when kerosene is filled in an 18-liter plastic container, the weight is about 15 kg, and a large amount of labor is required for transportation.

  For example, Japanese Patent Application Laid-Open No. 2004-26295 discloses one that facilitates transportation of this type of plastic container. What is disclosed in the publication is related to the title of the invention "Polytank for Movement", and aims to "provide a polytank that can be easily carried and at the same time the contents can be used up easily." FIG. 10 is an elevational view of the moving poly tank disclosed as the attached FIG. 1 in the publication.

In FIG. 10, reference numeral 101 denotes a moving handle, 102 denotes a moving plastic tank, 103 denotes a caster (moving vehicle), 104 denotes a bottom, 105 denotes a feeding port (feeding port), and 106 denotes a feeding port. (Feeding outlet), 107 is a fringe stop of the feeding / outlet pump, and 108 is a handle.
The “moving plastic tank” disclosed in the above Japanese Patent Application Laid-Open No. 2004-26295 is provided by “providing a moving handle and a caster” in the plastic tank (see claim 1 of the same patent claim). However, it can be easily moved "or the like (see paragraph number 0011 of the same publication).

  However, the polytank 102 shown here is simply a tank for transporting liquid made of polyethylene, and further equipped with wheels and expansion / contraction handles, and does not use a polytank that conforms to standards such as JIS. . As you know, poly containers suitable for safe storage and transportation of kerosene etc. must conform to JIS standard JISZ1710, not simply by attaching wheels to square containers. In addition, simply attaching a wheel and a telescopic handle to a square container causes problems in operation during transportation and workability for injecting and extracting kerosene and the like.

  That is, when carrying kerosene or the like and actually injecting kerosene into a tank such as a kerosene stove, it is necessary to use a pump or the like to draw it out from the inlet, etc. It is necessary to install, insert the nozzle into a tank inlet such as kerosene stove, lift the poly container, and even pour kerosene into the kerosene stove tank. For this reason, a lift handle for lifting is also required, as is the case with conventional plastic containers.
