Child-resistant blister packaging
- Fits the blisters you already use, no redesign needed
- Child-resistant and senior-friendly, both independently tested
- Runs on standard cartoning equipment at regular production speed
Compliance should not force you to redesign your product
When a product can harm a child, child-resistant packaging is not optional. But many routes to compliance carry a hidden cost. Either you change the blister or the lidding itself, which means new tooling and new validation, or you end up with a pack that older patients struggle to open. Neither is acceptable when you need to bring a product to market on time.
The Locked4Kids carton takes a different route. The child-resistance is built into the carton, so your blister stays exactly as it is.
How the Locked4Kids carton works
Your blister strips sit in a tray inside the carton. The tray slides out like a drawer, but only when two hooks on top of the carton are pressed at the same time. The hooks are placed diagonally, on opposite sides.
Children cannot open it. They do not understand the mechanism, and their hands are too small to reach both hooks at once. An adult opens it in one simple movement. Because every component stays firmly connected, the pack closes again and stays child-resistant for the full course of treatment.
Child-resistant is only half the job
A pack that stops a child but also stops an older patient with arthritis is a failed pack. Child-resistant packaging only works if the patient can still reach their medication. In testing, every senior who tried opened the Locked4Kids packaging successfully, with no strength and no complicated movement required.
The packaging is certified to ISO 8317 for Europe and F=1 under US 16 CFR 1700.20 for the United States. Testing was carried out at BVI in Belgium, an ISO 17025-accredited laboratory. In a panel of 300 children, fewer than 1% opened the packaging before a demonstration and fewer than 4% after two five-minute rounds, against regulatory thresholds of 15% and 20%.
No new production line. No speed penalty.
The carton is built for high-speed automated production on standard pharmaceutical packaging equipment, including lines from Romaco, Uhlmann and Pentapack. Blister strips are loaded and inserted at the same speed as regular, non-child-resistant cartons.
The design can be customised to your product: single or multiple strip locking trays, clamshell designs, window packs, and inner or outer lidding. Both highly automated production and smaller hand-assembled runs are possible, so large and limited volumes both work.

Questions packaging teams ask
Does it work with our existing blister format?
Yes. The platform fits around 95% of blister packs currently on the market.
Do we need to change our blister or lidding?
No. The child-resistance is in the carton. Your primary blister integrates as it is, with no modifications needed.
Will it slow down our packaging line?
No. The carton runs on standard cartoning equipment at the same speed as regular, non-child-resistant cartons.
Is it senior-friendly?
Yes. Every senior tested opened the pack successfully, with no strength required.
Which markets does the certification cover?
The packaging is certified to ISO 8317 for Europe and to F=1 under US 16 CFR 1700.20 for the United States. It meets the Poison Prevention Packaging Act.
Can the carton be customised to our product?
Yes. Single or multiple strip locking trays, clamshell designs, window packs and inner or outer lidding are all available.
What volumes do you support?
Both highly automated production and smaller hand-assembled runs, so large and limited volumes are both possible.
