Caps & Closures

Find the right cap or closure for every container you carry. The Bottle Depot stocks wholesale caps and closures for glass bottles, jars, and vials — including screw caps, lotion pumps, fine mist sprayers, glass dropper tips, roller balls, bamboo lids, and aluminum jar lids. Whether you're sealing a 0.5 oz tincture bottle or a 16 oz pump bottle, we carry bulk closures sized to fit. Browse by type below, or use the filters to match your container's neck finish. Browse black closures, white closures, and more.

Screw Caps & Specialty Bottle Closures

Our bottle caps and closures cover the full range of neck finishes — including popular 28-400 caps with liners, plus 18-400 and 24-410 sizes compatible with Boston round, packer, syrup, and Euro-style glass bottles. Available in black and white with PE, foam, or pressure-sensitive liners for a leak-proof seal. For food, beverage, and essential oil applications, these screw caps provide a clean, tamper-resistant closure that holds up to shipping and storage. Sold in bulk quantities to keep your production line moving.

Pumps, Sprayers & Dropper Tips

Dispensing closures make a real difference in how customers experience your product. Our lotion pumps fit a range of bottle sizes — including pumps sized specifically for 16 oz bottles — and are well-suited for serums, lotions, shampoos, and body washes. Fine mist sprayers work for toners, facial mists, and cleaning formulas. Glass dropper tips are compatible with our amber and clear Boston round dropper bottles and sized for precise dispensing of tinctures, CBD oils, and essential oil blends. Roller balls are also available for roll-on perfume and oil applications.

Bamboo & Aluminum Jar Lids

Give your jars a finished look without sacrificing function. Our bamboo lids are a popular choice for candle brands, body butter, and artisan food products — they photograph well and communicate a natural, premium aesthetic. Aluminum lids offer a sleeker, more contemporary finish with excellent durability. Both are available through our full jar lids collection and compatible with several of our glass jar sizes. If you're building a private label line, a well-matched lid is one of the simplest ways to make your packaging look intentional.

Frequently Asked Questions

How do I know which cap fits my glass bottle?
Caps are sized by neck finish — a two-number code like 28-400, where the first number is the diameter in millimeters and the second refers to the thread style. Most of our Boston round bottles use 18-400, 20-400, or 28-400 finishes. Check your bottle's product page for the neck finish spec, then filter our caps collection by that size. When in doubt, order a sample first.

Do your caps come with liners?
Most of our screw caps include a PE or foam liner for a leak-proof seal. Liner type is noted on each product page. If you're packaging liquids — especially oils, tinctures, or anything acidic — a lined cap is the right choice. Unlined caps are typically used for dry goods or applications where airtight sealing is less critical.

Can I order caps without buying bottles?
Yes. All caps and closures are sold separately and available in bulk quantities. This is useful if you already have containers and just need to stock up on closures, or if you're testing a new dispensing format before committing to a full order.

What's the minimum order quantity for caps?
Minimums vary by product. Many of our bulk caps are available starting at quantities that work for small-batch producers, with per-unit pricing that drops as quantity increases. Check individual product pages for MOQ and pricing tiers.

Do you carry child-resistant closures?
Yes — we carry child-resistant (CRC) caps suitable for supplement, tincture, and pharmaceutical-adjacent applications. These are listed within the bottle caps category and can be filtered by size.

How fast do caps ship?
Orders ship within 3–5 business days to anywhere in the contiguous United States. We've served 5,000+ customers since 2018 and stand behind every order with a satisfaction guarantee. If something's wrong, we'll make it right.
