Why Disc Top Caps?
Disc top caps are the standard for one-handed dispensing in personal care. The push-open, pull-close mechanism controls flow without contact, making them the default closure for shampoo, conditioner, and body wash formats.
HB Packaging manufactures 33 disc top SKUs across 18–28mm neck finishes, with in-house mold capability for custom orifice sizing, color, and surface finish. For brands that need a reliable, factory-direct disc top at scale, this is the range to start from.



Choose the right liner for disc top caps
A good liner choice starts with your formula, bottle neck, filling process and how the product will ship, not the cap alone.
Often no liner; add foil for water-based formulas
Disc top caps can be sourced with or without a liner. If the product is water-based or likely to travel under pressure changes, specify an induction foil seal and run leak testing before bulk order.
Common order setups
No Liner
Best when the cap, bottle finish and formula pass leak testing.
Foil seal
Useful for watery formulas, freshness and extra shipping confidence.
Confirm the final setup with your formula, bottle material, neck finish and filling temperature before bulk production.
