Unlocking Packaging Safety: The Genius of MedLock’s CR/TE Caps

When it comes to regulated cannabis packaging, the closure is where safety begins. It’s the point where compliance meets design—and the smallest component can make the biggest impact on your product’s integrity. MedLock’s Click-Lock™ closure system redefines what’s possible by combining child resistance (CR) and tamper evidence (TE) into a single, intuitive twist. For licensed producers across Canada, this innovation simplifies compliance, reduces operational costs, and protects consumer trust at every turn.

The Science Behind the Click

At first glance, the Click-Lock™ cap may seem simple. But beneath its smooth exterior lies a system of engineered precision. Each cap includes torque-stop teeth, a gasketed seal, and a frangible tamper band—three key components that deliver the highest level of regulatory safety without slowing production lines.

• Torque-stop teeth prevent over-tightening, ensuring a consistent seal on every container.

• The inner gasket and valve create a leak-proof barrier for liquids, oils, and tinctures.

• The frangible band breaks visibly upon first opening, providing tamper evidence without the need for secondary seals or heat bands.

This patented one-step design eliminates the need for separate tamper-evident bands and simplifies filling operations—a major advantage for high-throughput cannabis producers who demand both speed and safety.

Certified Protection in One Motion

Every Click-Lock™ closure is independently tested and certified to meet or exceed global safety standards: CPSC 16 CFR 1700.20, ISO 8317, FDA, and Health Canada ACMPR. These certifications verify that each cap requires a defined combination of strength and dexterity to open—child-resistant for those who need protection, yet simple for adults to access responsibly.

Unlike multi-part closure systems, the Click-Lock™ delivers this performance without added assembly or shrink sealing. This not only saves time but also reduces material use, energy consumption, and equipment maintenance.

In short: one cap, one motion, total compliance.

Engineered for Every MedLock Container

The Click-Lock™ closure system secures every major MedLock packaging format:

• PET Jars for dried flower and concentrates

• PET and Amber Glass Bottles for oils, tinctures, and extracts

• Pop-Top Vials for capsules and edibles

• Packer Bottles for confection and supplement lines

Each pairing maintains consistent CR/TE functionality across formats, making compliance seamless throughout your product line. LPs can standardize closures, simplify SKU management, and streamline regulatory documentation—all without sacrificing design flexibility.

The Consumer Experience: Secure, Yet Simple

True compliance should never frustrate the end user. MedLock’s engineering team focused on creating a closure that feels natural in the hand, with smooth torque and clear tactile feedback. The “click” confirms secure locking—both for the consumer and the fill-line operator.

This combination of form and function turns safety into an experience. It’s packaging that communicates trust through sound, touch, and consistency.

Consumer benefits:

• Easy, intuitive opening for adults

• Clear audible “click” when sealed

• Visual tamper indicator for reassurance

• Re-closable, leak-proof performance for repeated use

 

Aesthetic and Branding Flexibility

Safety doesn’t mean sacrificing style. Click-Lock™ caps can be Pantone® colour-matched and produced in matte, gloss, or textured finishes to align with your brand’s visual identity. Custom geometries and engravings are available for premium or limited-edition products, providing brand differentiation while maintaining certification compliance.

Whether you need a sleek matte black finish for a premium extract line or a colour-coded cap system for product segmentation, MedLock’s in-house customization service makes it possible—all while maintaining CR/TE certification integrity.

Simplifying Operations and Reducing Costs

The Click-Lock™ closure was designed not just for compliance, but for efficiency. By removing the need for heat-shrink bands and additional sealing steps, it reduces:

• Capital equipment investment

• Energy consumption on filling lines

• Operator time per unit

• Material waste from secondary seals

LPs gain faster throughput, lower overhead, and fewer points of potential error. Combined with MedLock’s in-stock availability and low MOQs, this closure system supports agile operations and scalable growth.

Compliance, Safety, and Sustainability in One Cap

MedLock manufactures Click-Lock™ closures in both HDPE and EcoPure® biodegradable resin. Both materials are fully recyclable, and the EcoPure® variant is certified biodegradable under ASTM D5511. This ensures every cap aligns with sustainability goals while maintaining safety and compliance standards.

By integrating CR/TE features with sustainable materials, MedLock helps LPs meet regulatory, environmental, and consumer expectations simultaneously.

The Genius Is in the Details

MedLock’s Click-Lock™ closure embodies the company’s philosophy: innovation through compliance. It’s a simple design that solves complex problems—meeting safety standards, lowering costs, and improving the user experience all at once.

For LPs, this means fewer steps to achieve full certification and complete peace of mind at every audit. For consumers, it means confidence in every click.
