5ml Heavy Bottom Child Resistant Jar with Black Lids

The 5ml Heavy Bottom Child Resistant Jar with Black Lids is a compact glass container designed for extractors, processors, and cannabis brands packaging single grams or small concentrate samples. The thick base prevents tipping during filling operations and gives retail displays a premium feel, while the push-and-turn child-resistant lid meets safety expectations without adding hassle to your workflow.

Key benefits

• Stays put on busy benches — The heavy-bottom design keeps jars planted when you're filling a dozen at a time, no more chasing tippy containers across your work surface.
• Built-in compliance layer — Child-resistant black lids add protection for mixed-use spaces and retail environments where safety matters.
• Right-sized for grams — 5ml capacity fits typical single-gram fills without wasting headspace or making your product look lost in an oversized container.
• Show off what's inside — Clear glass lets customers see color, clarity, and texture at a glance, which moves product faster than opaque packaging ever will.
• Clean, brandable look — The contrast of clear heavy glass with a matte black lid gives you a professional baseline that works with custom labels or minimal branding.
• Stacks and stores efficiently — Uniform dimensions mean these play nice with trays, bins, and inventory systems you're probably already running.

Best for

Licensed extractors and processors running compliant packaging programs will get the most value here, especially if you're filling retail grams or building sample packs for buyers. Home pressers and concentrate collectors who want their personal stash in the same quality glass they see at dispensaries will appreciate the upgrade from flimsy plastic containers. These also work well for brands still dialing in their packaging identity — the neutral black-and-clear aesthetic pairs easily with other glass jars and packaging formats without clashing.

How to use it

Fill each jar with your concentrate, leaving a small gap at the top so the lid seats cleanly without smearing product on the rim. Press down and twist the child-resistant lid until it clicks into place. That secure fit locks in terpenes and keeps the jar sealed until someone with the coordination to push-and-turn opens it.

For batch filling, line jars up on a dab mat or clean tray to keep your workspace organized and catch any drips. Once filled, label each one with strain info, batch numbers, dates, or whatever tracking system your operation runs. Store filled jars upright in bins or drawers with your other storage and packaging supplies.

When it's time to clean empties for reuse, let any residue cool completely, then soak jars and lids in isopropyl alcohol. Rinse with warm water and let everything air dry before the next round.

Specifications

Fit and compatibility

The 5ml format slots into most standard lab trays, display inserts, and foam cutouts designed for concentrate packaging. If you're already running 5ml glass in your operation, these should drop right into existing workflows. The jar dimensions also accommodate common label sizes used in dispensary and lab settings, so you won't need to redesign anything to start using them.

One thing to note: these are optimized for smaller fills. If you're packaging half-grams, 5ml gives you comfortable headroom. For two-gram fills or bulkier textures like sugar or crumble, you might find yourself wishing for a larger jar.

FAQ

• How much concentrate actually fits in a 5ml jar?
  Most extractors use these for single-gram fills of wax, shatter, rosin, or similar textures. Dense concentrates pack more mass into the same volume, while whipped or airy textures take up more space. Plan on comfortable gram fills with a little room to spare for the lid to close cleanly.
• Is the child-resistant lid actually effective?
  Yes. The push-and-turn mechanism requires coordinated pressure and rotation to open. Adults figure it out quickly, but it creates a real barrier for young children. It's the same style of closure you see on prescription bottles and compliant cannabis packaging.
• Can I reuse these after cleaning?
  For personal use, absolutely. Soak in isopropyl alcohol, rinse thoroughly, and let them dry completely before refilling. For commercial reuse, check your local regulations — some markets require single-use packaging, while others allow sanitized containers. Treat these like you would any other concentrate jars in your workflow.
• Will these work with my existing display cases?
  Most likely. The 5ml heavy-bottom format is common enough that standard tray inserts and display systems accommodate them. If you're switching from a different 5ml jar, measure the base diameter to confirm, but compatibility is rarely an issue.
• What tools do I need for filling?
  Nothing special. Standard lab spatulas or dab tools work fine for portioning product into the jars. For especially sticky concentrates, some processors prefer working over nonstick paper to catch any drips.
• How long can I store concentrates in these?
  Glass with a tight seal is solid for medium to long-term storage when you keep jars cool, dark, and away from temperature swings. The heavy-bottom construction handles minor bumps better than thin-walled alternatives, and the child-resistant lid maintains a good seal. For archival storage of large batches, some operators pair glass jars with additional barrier materials like mylar bags for extra protection.
• Can I use these for non-cannabis products?
  Definitely. The 5ml size and premium construction work just as well for cosmetic balms, salves, small samples, or lab specimens. They're essentially high-quality sample jars that happen to be optimized for concentrate workflows.

For operations standardizing their packaging, these 5ml jars deliver the combination of safety, visibility, and professional presentation that makes retail products look intentional rather than thrown together. According to Leafly's concentrate guide, proper storage containers help preserve terpenes and potency — and heavy-bottom glass does that job while looking good in the display case.
