A Secure Close, Matched to the Glass
Closing
Screw caps, stoppers, and lids seal the bottle or jar between uses, protecting the contents from air, moisture, and contamination. Each is matched to its corresponding Miron® glass format by thread size, ensuring a secure and consistent close.
Screw caps are available in a wide range of thread sizes including DIN18, PP28, 31.5 STD, and 24/410, with surface options in ribbed, matt, and smooth. Each includes a violet PHAN sealing element, a three-layer laminate of PET film and EPE foam that provides an airtight hermetic seal. Tamper-evident and child-resistant variants are available, with Series II and Series III cap designs offering different levels of tamper protection. Lids are available in classic and modern styles for Miron cosmetic and vitamin jars with special threads. Stoppers are available for the Libra and Lyra apothecary jar range.
Closing closures are available in multiple finishes, including black, gold, and silver.

Yes. Samples are available for screw caps, lids, and stoppers. We recommend testing the closure together with the corresponding Miron bottle or jar to evaluate fit and seal quality before committing to a full order. Select the closure on the product page and add it to your
Miron offers three categories of closing closure: screw caps, lids, and stoppers. Screw caps are suited for bottles with standard thread finishes. Lids are designed for cosmetic and vitamin jars with special threads. Stoppers are available for the Libra and Lyra apothecary jar range. Each is matched to its corresponding glass format to ensure a secure, consistent close.
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 Miron screw caps and gives each cap a distinctive violet inlay.
Miron screw caps are available in DIN18, PP28, 31.5 STD, and 24/410 thread sizes, covering the full range of Miron bottle formats. The correct thread size for each bottle is listed on the individual product pages. If you are unsure which screw cap fits your bottle, our sales team is available to advise.
Series II closures are made from a single mold with 4 to 6 ridges on the side and a tamper-evident ring at the bottom that breaks on first opening. Series III closures have a thicker rim, are made from multiple molds, and use retention fingers on the tear strip rather than ridges, making them more difficult to manipulate and giving them a more refined appearance. Both provide tamper evidence. The choice between them depends on your product, your market, and the level of protection required.
