This product is a finalist in the category Packaging: Design & Materials of Cosmopack 2026
Product Description (No Prototypes accepted)
PURO is an aerosol applicator that spotlights a patent-pending telescopic cut-off mechanism integrated into the applicator. This technology actively closes the dispensing orifice immediately after actuation, thus interrupting product flow and eliminating product build-up. This action distinguishes PURO from standard aerosol actuators, which retain product after use. Instead, PURO actively controls the packaging’s post-dispense behavior, allowing for cleaner dispensing, improved hygiene, and consistent performance for foaming, gel, and post-foaming formulations. Among the innovation’s benefits are enhancing user experience by removing the need to repeatedly clean the applicator after use and improving retail tester presentation, keeping displayed products clean and visually appealing. The packaging is presented as a single-material, PCR-compatible design, offering a functional breakthrough without brands having to alter their formulations or filling processes.

Product Innovation
PURO introduces a novel approach to aerosol dispensing by integrating a patent-pending telescopic cut-off mechanism directly into the applicator. This technology actively closes the dispensing orifice immediately after actuation, interrupting product flow at the source and eliminating residual product build-up. Unlike standard aerosol actuators, which passively retain product after use, PURO actively controls post-dispense behaviour. The innovation enables cleaner dispensing, improved hygiene, and consistent performance for foaming, gel, and post-foaming formulations. Combined with a single-material, PCR-compatible design and standard 1” fit, PURO delivers a functional breakthrough without altering formulations or filling processes.

5. Enhances user experience by removing the need to clean the applicator after use
6. Improves retail tester presentation, keeping displayed products clean and visually appealing
7. Features a large, ergonomic finger pad for comfortable and intuitive actuation
8. Supports a wide range of application formats, including shower foams, shaving foams, gels, and post-foaming products
Research, Clinical Tests & Trials Results (Safety & Dermatological)
Consumer application testing (n=30 users, mixed gender, ages 20–55)
• 96% of participants correctly understood and operated the applicator mechanism on first use without instructions
• 87% of users rated the applicator as noticeably cleaner compared to standard foam and gel actuators
Observed use and behaviour testing (multiple-use cycles)
• 100% elimination of delayed foaming leakage observed in repeated tests with foaming and post-foaming formulations
• 0 visible residue under the overcap after use, even after extended standing time
Retail and hygiene-related evaluation
• 85% of participants stated they would prefer PURO-equipped products for shared or tester use due to improved hygiene
• Testers equipped with PURO remained visually clean and presentable throughout the testing period, with no uncontrolled foam release
Certifications, Patents & Regulatory Compliance

Sustainability List of Certifications
Puro is designed with sustainability in mind and to meet upcoming PPWR (Packaging and Packaging Waste Regulation) requirements. The applicator is a mono-material PP solution, without inserts unlike many other applicators, which improves recyclability. It can also be produced using PCR material, further reducing environmental impact. As a company, we are strongly committed to environmental protection and responsible production. We hold the following certifications: ISO 9001 – Certified Quality Management System supporting controlled and resource-efficient production, ISO 14001 – Certified Environmental Management System, ECOCERT COSMOS certification supporting sustainable and responsible solutions.
How to use it
1. Remove the overcap or unlock the safety mechanism, if applicable
2. Press the applicator to dispense the product as intended (foam, gel, or post-foaming formulation)
3. Release the applicator after use. The cut-off mechanism automatically closes the orifice, preventing residue and delayed foaming
4. Replace the overcap or lock the applicator after use
5. Use the product according to the cosmetic formulation instructions (daily, weekly, morning or evening, depending on the product)
6. No cleaning of the applicator is required between uses
7. Continue using until the product is finished
