Abstract: A cleaner structure includes a main body, a forced element and an elastic element. The main body includes a first casing, a floating element, a second casing, first perforations and second perforations. The floating element is disposed within the first casing. The second casing is connected with the first casing for storing a cleaning agent. The elastic element is connected with the first casing and the forced element. During the water level of the liquid inside the toilet tank is changed from a low level to a high level, the second casing is at least partially immersed in the liquid, so that the cleaning agent is released to the liquid.

Abstract: A precipitated film and the fabricating method thereof are disclosed. The precipitated film includes a supporting layer having columnar crystals, and a functional layer formed on the supporting layer and having granular crystals. The precipitated film is fabricated by phase-changing one of two aqueous solutions, which are able to react with each other to form a solid precipitate inherently, into solid-state and then reacting with the other aqueous solution to form the precipitated film by a precipitation reaction.

Abstract: A method for forming structured or micro-structured film comprising the steps of: A. Coating a photocuring or heat-curing adhesive resin layer on a substrate layer; B. Molding or forming or imprinting a structured or micro-structured pattern including prismatic array on the adhesive resin layer by a tape die having the structured pattern preformed on the tape die; and C. Curing the photocuring or heat-curing adhesive resin layer on the substrate layer to obtain a layered film having a structured pattern surface. The structured pattern is formed on the tape, rather than on the rotary die or die roller, to prevent from sticking of the adhesive resin on the roller to prolong the service life of the production equipment and also to ensure a reliable film product quality.
