Because the container of this prior art is actually two containers, a bulge is promptly arranged in a rectangular vessel, the correlative charges of therefore making this container can be too high.And, because pressure fluid just is stored in the circular portion of container, be not utilized around the inside of the rectangular vessel of bulge.Therefore, this container can not be optimized shelf storage.

Also have, be used to store and disperse the container of pressure fluid to have manual pumps usually to the liquid supercharging.A problem of conventional pump relates to the location and the configuration of pump handles.Existing conventional pump handles is to integrate to be fixed on the tang of pump handles.The projection at this container assemblies top has hindered the storage convenience of container assemblies, perhaps piles up other containers or object thereon.

The configuration of conventional pump has increased the possibility of infringement handle and tang in addition, because outstanding on the handle slave unit, can't resist the object that may fall and the bump of other objects.

Therefore, the pressure container that needs a kind of single container of non-circular horizontal cross section in the prior art.In addition, also need to have the pressure container of folding type inflatable pump handle in the prior art.In addition, also need a kind of pressure container that can pile up with effective and efficient manner in the prior art.
