Before ordering a full carton, check these points:<\/p>\n<ol>\n<li><strong>Izvedba vratu.<\/strong> Confirm the bottle is DIN18 (GL18). Our guide on how cap thread is measured shows how to verify this.<\/li>\n<li><strong>Teat and pipette.<\/strong> The collar must work with the teat size and pipette length you plan to use. A longer teat or a different pipette changes how the assembly sits.<\/li>\n<li><strong>Bottle and collar together.<\/strong> Thread a sample collar onto a sample bottle and check that it seats evenly with no wobble.<\/li>\n<li><strong>Your product.<\/strong> Test the actual formula with the actual materials, particularly if it is an essential oil blend or a solvent-containing product, since these can affect the teat and other parts over time.<\/li>\n<li><strong>Your process.<\/strong> If you apply collars by hand, grip and ring design matter more. If you use a capping machine, run a short trial first.<\/li>\n<\/ol>\n<h2>Common mistakes when selecting collars<\/h2>\n<ul>\n<li><strong>Izbira samo po barvi.<\/strong> A gold collar may look perfect and still lack the tamper-evident ring your retailer requires.<\/li>\n<li><strong>Me\u0161anje tipov vratu.<\/strong> Similar-looking collars with different threads will not seal properly.<\/li>\n<li><strong>Izpu\u0161\u010danje poskusnega zagona.<\/strong> Problems with fit or appearance show up quickly in a small trial and expensively in a full batch.<\/li>\n<li><strong>Treating child resistance as a styling choice.<\/strong> It is a functional and regulatory topic.

Lead time is typically 3-5 working days from payment, and we ship across the EU and the UK. If you are not sure which collar suits your product, order samples first and test them with your own bottles, teats and pipettes. We can also assemble complete droppers if you prefer to receive finished parts.<\/p>\n<h2>Pogosta vpra\u0161anja<\/h2>\n<h3>Do all collars in this range fit DIN18 (GL18) bottles?<\/h3>\n<p>Yes. Every collar in the Collars &#8220;SecureSeal&#8221; category is designed for DIN18 (GL18) bottle necks. Check your bottle&#8217;s neck finish before ordering.<\/p>\n<h3>Which collars have a tamper-evident ring?<\/h3>\n<p>The black and white ribbed PP collars, the prominent-ring black collar and the SecureFlow CRC\/TE collars. The aluminium and wooden collars do not have a tamper-evident ring.<\/p>\n<h3>Are aluminium collars fully metal?<\/h3>\n<p>No. The outer shell is aluminium, but the inner thread is polypropylene.<\/p>\n<h3>Can I request samples before ordering a carton?<\/h3>\n<p>Yes.
