31.5 mm Tamper Evident Cap with Integrated Orifice Reducer (Pourer Insert)
The 31.5 mm tamper-evident cap with an integrated orifice reducer is a reliable and efficient closure designed for oils, vinegars, syrups, sauces, and flavored spirits. Moreover, it ensures smooth and controlled dispensing, which significantly reduces spills and product waste. As a result, it provides a clean and user-friendly pouring experience.
This closure features a precisely engineered LDPE flow-reducer insert that offers a steady and drip-free stream. In addition, the HDPE outer cap includes a ribbed surface, allowing users to grip and open the bottle effortlessly. When the cap is first applied, it seals tightly; however, once opened, the tamper-evident band separates, leaving a visible ring on the bottle neck. Therefore, consumers can easily detect whether the product has been previously opened.
Made from food-grade and BPA-free materials, this closure is suitable for both industrial production and home bottling. Furthermore, it is compatible with a wide range of 31.5 mm glass bottles, including Marasca, Dorica, Quadro, and standard oil or syrup bottles. Consequently, it serves as a versatile solution across multiple industries.
