Sealed Freshness Bread Box with Adjustable Vents

Dimensions: 28 × 17 × 14 cm external; internal usable height 12 cm supports vertical storage of most UK supermarket loaves (e.g., Warburtons Medium, Hovis Soft White). Weight: 420 g—balanced for one-handed lifting yet stable enough to remain upright when filled. Capacity: Confirmed capacity for one 800 g loaf + two wrapped sandwiches, or eight standard bagels in concentric arrangement. Material: Recyclable polypropylene (PP5) with matte surface and non-reflective finish—resists fingerprint smudges and cleans easily with soapy water or vinegar solution. Three interlocking systems define performance: the lid’s continuous sealing lip compresses evenly on closure; valves rotate 90° between fully open (max airflow) and fully closed (minimal exchange); date zone uses chemically treated surface for reliable dry-erase adhesion without ghosting. No batteries, no apps, no consumables—just mechanical reliability aligned with EU Ecodesign principles of repairability and longevity. Adapted for British living patterns: works equally well in rural cottages with variable humidity, urban flats with central heating dryness, and coastal homes prone to salt-air exposure—the sealed + vented hybrid approach delivers consistent results regardless of local microclimate conditions.
