<p>The present invention concerns a vessel comprising an integrated tube-and-cap assembly, wherein one or more tube(s) is connected by way of one or more hinge strap(s) or device(s) to one or more cap(s). The assembly is fabricated in one piece, wherein the tube and the cap have different light transmitting properties, since the material of either one or both of the tube and the cap comprises one or more colorants, which alter its light transmitting properties, and wherein the materials of the tube and the cap do not comprise the same colorant or mixture of colorants.</p> |
