Universal frame forming device for e.g. photograph, has multiple transparent tubes, where one tube has orifice through which liquids or solids are introduced into inner space of tubes and orifice is closed by plug after filling tubes

摘要

The device has several transparent tubes (1-4) with round, square or rectangular sections and assembled by sticking or welding to render tight connection of the tubes to form a frame made of polymethyl methacrylate. One of the tubes has an orifice (5) through which liquids or solids are introduced into an inner space of the tubes. The orifice is closed by a plug (6) after an operation of filling the tubes.
