Hobbocks with clamping rings – can be reclosed easily any number of times

The ideal hazardous materials container: Hobbocks with clamping ring

Hobbocks are conical metal buckets starting at a capacity of about 12-litres. Due to their conical shape, when empty these tinplate containers (tinned sheet steel) can be easily nested, thus saving space.

The ringless bucket edge makes it easy to pour out the contents cleanly. A rubber seal in the lid ensures a high degree of tightness and storage stability.

The interior of our hobbocks are available either coated or uncoated, so that products that contain water can also be safely filled and stored. They are also suitable for storing food. In this case, a food-compliant internal coating is used as standard.

Suitable for a wide range of products, from wet to dry, heavy to light

Depending on the application, hobbocks are available from a design with a simple press-in lid (for example, for storing solid filling materials such as dry pet food) to a "heavy-duty" version with clamping ring for transport and secure storage of products classified as hazardous materials.

We also offer the option of a clamping ring hobbock in a light version (Flex) with a slightly thinner body that is approved for RID-ADR hazardous goods handling (suitable for transport by road or rail), or in a slightly thicker body plate for approval according to UN standards (for transport by ship or plane).

AirLock – the innovative solution for automated sealing of clamping ring containers

Pirlo’s hobbocks can be closed automatically using our specially developed sealing machine technology. The AirLock sealing machine works purely pneumatically, as it was designed for use in potentially explosive atmospheres. The tamper-evident seal with a safety pin is created on a patented belt magazine. The Airlock can be integrated into a filling line, where it can safely and reliably seal up to 6 containers per minute (depending on the package design and filling conditions). The containers range in sizes from 5-litres to 30-litres.
