Reed Diffuser Caps & Stoppers

Reed diffuser caps and stoppers coordinate the bottle opening, transport seal and decorative presentation of the finished diffuser. A decorative collar or cap should not automatically be treated as the shipping seal; many projects use a separate plug or stopper before the consumer installs the reeds.Confirm the exact bottle opening, plug or stopper dimensions, fragrance contact, reed clearance and cap height on a filled sample. Test leakage during packing and transport, then check that the consumer can remove the seal and install the intended reed bundle without damaging the decoration.

Key Considerations for Reed Diffuser Caps & Stoppers

Measure the bottle opening and neck, then confirm plug insertion, stopper depth and decorative cap or collar fit on the exact bottle.

Sealing Performance

Test the filled bottle with the transport plug or stopper for leakage under the intended packing and shipment orientation.

Liner / Plug

The plug or stopper may be separate from the decorative display cap. Confirm material contact with the intended fragrance formula.

Decoration Options

Coordinate cap or collar color, metal finish, printing or other branding with the bottle decoration and gift box.

Testing Requirements

Validate leakage, plug retention, consumer removal, reed clearance, fragrance compatibility and surface contact on filled samples.

Assembly & Packing
