Updated:

Package safety incidents involving children remain a significant concern, with over 85,000 cases of accidental exposure to household chemicals and medications reported annually in the US alone. Current child-resistant packaging standards require that 85% of children under age 5 cannot open a package within 5 minutes, while 90% of adults between 50-70 years must be able to open it within the same timeframe.

The fundamental challenge lies in creating mechanisms that effectively discriminate between adult and child interactions while maintaining accessibility for seniors and those with limited dexterity.

This page brings together solutions from recent research—including deformable cap regions with rib-slot engagement, stretchable aluminum foil designs for blister packs, asymmetric seal mechanisms, and sensory deterrent features. These and other approaches focus on meeting safety standards while ensuring practicality for manufacturing and everyday use.

Child-resistant packaging for containers like bottles with a cap that prevents unintentional opening by kids. The cap has two deformable regions that, when pressed, release ribs that engage projections on the container. Rotating the cap allows it to slide off. The ribs in slots on the neck deform and move to wider sections as they rotate, allowing full removal. The deformable regions provide grip for intentional opening. The ribs and slots distribute forces to prevent unintentional rotation. The cap has instructions for opening.

4. Child-Resistant PTP Packaging Lid with Stretchable Soft Aluminum Foil

株式会社タケトモ, TAKETOMO KK, TAKETOMO CO LTD, 2024

Child-resistant lid material for PTP medication packaging that allows adults to easily remove the medication while making it difficult for children. The lid uses a thin, soft aluminum foil instead of a resin film. The soft aluminum foil stretches more than regular foil, making it harder to push out the medication with a small force. The foil thickness is 25-33 microns and the Mullen burst strength is 225-300 kPa. This provides senior-friendly ease of opening while being difficult for children. The soft aluminum foil is preferably 17-45 microns thick and alloy numbers 1N30, 8079, or 8021. The foil extrusion strength is at least 35N to prevent easy removal. The lid can have additional layers like a heat seal, printed layer, and overprint

10. Asymmetric Seal Bar Design for Child-Resistant Pouch Closure

QINGDAO DEJILI PACKAGING TECHNOLOGY CO LTD, QINGDAO DEJILI PACKAGING TECH CO LTD, 2024

Child-resistant sealing pouch with a unique design to prevent accidental opening by children. The pouch has a seal bar with two closing pieces that buckle together to seal. The upper extension piece of one closing piece is thermally connected to the inside of the pouch, but the other closing piece has an unconnected upper extension. The lower extension of the other closing piece folds up and attaches to the inside. This asymmetry in the closing piece extensions makes it harder for children to tear the seal apart since the forces don't align. It also prevents them from just pulling the top apart since it's connected to the pouch.
