Introduction of 18 L Open Head Metal Pail, Unlined Interior, Lever Lock Ring Lid

The 18 L open head metal pail is a heavy-duty open-top steel packaging container fitted with a lever lock ring (clamp ring) lid and bare unlined interior. It is designed for easy full opening, filling, scooping and inspection, widely used for industrial solids, semi-solids and compatible non-corrosive liquids.

Basic Specifications

Nominal capacity: 18 Liters

Material: Prime cold-rolled carbon steel / tinplate

Type: Open head, fully removable lid

Interior: Unlined bare steel, no epoxy, phenolic or any protective coating

Closure: Lever lock ring lid with rubber gasket; hand-operated lever clamp, no tools required for opening and closing

Handle: Swing metal bail handle with plastic grip for easy carrying

Exterior: Custom paint colour, offset printing or plain finish available

Certification: UN marking optional for dangerous goods packaging upon request

Key Advantages

Tool-free lever lock ring: Fast, reliable sealing and re-opening. Compared with lug lids, the lever clamp delivers more consistent compression and better leak resistance for transport and stacking.

Full open access: The entire lid can be removed, convenient for bulk filling, scooping, cleaning and visual checking of contents.

Unlined bare steel: Lower cost; suitable for products compatible with plain steel, no risk of lining peeling or contamination from coating.

High mechanical strength: Good impact, puncture and stacking performance for warehouse storage and overland/sea shipment.

Reusable & recyclable: Steel is 100% recyclable; the lock ring and gasket can be replaced for repeated use.

Flexible customization: Gasket material (nitrile, EPDM, silicone etc.) can be selected to match packaged goods.

Typical Applications

Only for materials compatible with bare steel (non-acidic, non-corrosive):

Paint, putty, plaster, construction fillers

Non-corrosive greases, waxes, pastes

Powder additives, granules, masterbatch

Hardware parts, workshop bulk storage

Non-aggressive industrial oils and compounds

Important Notes

The unlined interior will rust when exposed to water, acidic or solvent substances. Not suitable for corrosive, water-based or chemically aggressive products; always run compatibility test before mass packing.

Gasket selection is critical to avoid swelling, chemical attack or leakage.

If used for hazardous cargo, confirm UN certificate, marking and local transport regulations.
