Sealed and Protected
Screw caps
A secure, reliable close for every Miron bottle. Screw caps keep air, moisture, and contamination out. They protect the contents from filling to the last drop.
Available in PP28, DIN18, 31.5 STD, and 24/410 thread sizes, covering the full range of Miron® water bottles, syrup bottles, oil bottles, and dropper bottles. Choose between ribbed or smooth surface finishes depending on the look and grip feel you want to create. Each screw cap includes a violet PHAN sealing element, a three-layer laminate of PET film and EPE foam that provides an airtight hermetic seal with a distinctive violet inlay.
Tamper-evident options are available in Series II and Series IIID. Child-resistant variants require a push-and-turn action to open. All screw caps are made from PP or PEHD in black, and available in matte or glossy finishes.

Screw caps provide a secure, reliable close for Miron water bottles, syrup bottles, oil bottles, and dropper bottles. They protect the contents from air, moisture, and contamination between uses. Available in both standard and tamper-evident designs, they suit a wide range of food, cosmetic, and wellness applications.
Miron screw caps are available in PP28, DIN18, 31.5 STD, and 24/410 thread sizes. PP28 suits the Aquarius bottle range. DIN18 suits the Orion dropper bottle range up to 100 ml. The 31.5 STD suits oil bottles including the Castor and Pollux series. The 24/410 suits larger cosmetic and personal care bottles.
The violet PHAN sealing element is a three-layer laminate consisting of two outer layers of solid PET film and an inner layer of EPE foam. The foam core provides the resilience needed for an airtight hermetic seal, protecting the contents from air and moisture. It is a standard feature across all Miron screw caps and gives each cap a distinctive violet inlay.
Yes. Samples are available for screw caps. We recommend testing the cap together with the corresponding Miron bottle or jar to evaluate fit and seal quality before committing to a full order. Select the screw cap on the product page and add it to your sample request.
Miron screw caps are available in Series II tamper-evident design, with 4 to 6 ridges and a ring that breaks on first opening, and Series IIID, with a smooth finish, thick rim, and retention fingers for a more refined and secure close. Child-resistant variants require a push-and-turn action to open, making them well suited for pharmaceutical, supplement, and retail applications.
