PROBLEM TO BE SOLVED: To stably stack containers and provide a shading property and further make visible the liquid volume in the container from the outside, by constituting the container so that the upper face and the bottom face are mutually fitted, and mixing pigment or the like having a shading property at a specified ratio. SOLUTION: Projections 1, 1 are formed parallel on the upper central face of a thermoplastic polyethylene container body 10 colored in ultramarine and provided with a shading property, and the middle part is connected with a H-shape handle 2. And caps 14, 15 for inlet/outlet are provided at both sides. When these containers 10, 10 are stacked, the projections 1, 1 on the upper face of a lower container are fitted to the recessions 11 formed at the bottom face of the upper container to stabilize them. This shading container 10 is formed in the composition ratio of ultramarine of 9.88%, titanium oxide as white pigment of 6.15%, phthalocyanine blue dyes of 0.01%, solvent LPE-wax of 3.68%, and polyethylene resin pellet of 86.27%. |
