This invention pertains to a versatile and innovative mixing cap designed for efficiently combining two separate components such as liquids, powders, or granulated substances just prior to use. The cap features a inventive mechanism that includes a variable thickness rubber container for storing the additive substance and a pressing plate connected via a threaded hall bar. The pressing mechanism is activated by a user-operated press button, which enables controlled release of the substance through apertures in the container into a liquid held within an attached bottle. The cap's unique design allows for precise control over the amount of substance released, accommodating a wide range of material types and viscosities, from nano-scale particles to high-viscosity liquids. This controlled pressurized release mechanism ensures thorough mixing without clumping, enhancing the solubility and dispersion of the substances within the liquid.

The invention discloses a preparation system and method for adding functional substances into tows, and relates to the technical field of cigarette tow manufacturing. In order to solve the problems that in the prior art, particulate matter addition is limited by acetone or a water-soluble additive, solid particles are prone to agglomeration, and spinning is difficult, functional substances (such as inorganic particles and organic particles) and cellulose diacetate acetone slurry are subjected to high-shear sanding dispersion through a dispersion system (a sand mill with a cooling jacket); secondary agglomeration of particles is inhibited by using slurry viscosity, and uniform mixing is realized by adjusting sanding parameters. The method breaks through the addition limitation of insoluble substances, improves the dispersion uniformity and addition concentration of functional substances, is low in improvement cost, and is adaptive to an existing production line. The problem of dispersion of functional substances in the acetate fiber tow is effectively solved, and the functional application range of the tow is expanded.
