KEIRA stackable watering cans in 7:1 formation – 1L, 2L, 5L and 10L nested together

7:1 Stackable Watering Cans
Already PPWR 2030 Compliant

Only 14% empty space instead of 90%+ air.
Same quantity – 1 truck instead of 7. –86% CO₂

The Problem

Conventional watering cans waste 90% of every truck on air

Standard conical shapes cannot nest. Each truck ships mostly empty space — an enormous waste of fuel, logistics cost, and CO₂ emissions.

90% empty space

Conventional cans

14% empty space

KEIRA 7:1

From 12 August 2026, PPWR Regulation (EU) 2025/40 requires max 50% empty space.

Technology & IP Protection

Legally Protected for the Next 70+ Years

Copyright (Urheberrecht)

Cour d'Appel de Paris, 2017

The unique V-geometry of KEIRA watering cans has been confirmed as a copyrighted work of applied art by the Paris Court of Appeals. Protection lasts 70 years post mortem auctoris.

Gebrauchsmuster V2

Granted by DPMA

The one-piece Einschuss (single-injection) production method is protected as a utility model by the German Patent and Trade Mark Office. A technical barrier competitors cannot bypass.

Market Exclusivity

No one can legally copy the V-geometry

Combined copyright and utility model protection creates a dual legal shield. The KEIRA system is the only stackable watering can that can be legally manufactured and sold in the EU.
