Reed Diffuser Caps & Stoppers

Many reed diffuser products use a separate sealing plug or transport closure to reduce leakage during filling, packing and shipping. A decorative cap is not automatically the transport seal.

Match the plug or closure to the exact bottle opening and test it with the intended fragrance. Also confirm how the consumer removes the seal and inserts the reeds, and make sure the final retail pack has enough space for the bottle, cap, plug and reeds.

The opening determines how the reeds enter the bottle and contributes to the exposed liquid area, while reed quantity, diameter, material and length affect fragrance transfer and evaporation. A larger opening or more reeds does not automatically mean better performance and can shorten product life.

Test the actual fragrance base and reed set in the selected bottle under realistic room conditions, then balance scent output, evaporation rate and expected use duration before production.

Provide the exact container model whenever possible. If a model is not available, measure the finished opening or neck and include the dimensions that control component fit: outside and inside diameter, thread or crimp specification, rim or lid-seat geometry, relevant heights and any insertion depth.

For pumps, also provide the neck finish and required dip-tube length. For lids and stoppers, a technical drawing or physical sample is strongly preferred because nominal diameter alone does not describe threads, tapers, gaskets, inserts or fit tolerances.

Separate accessory orders may be possible, but compatibility must be confirmed before production. Provide the Bright Glassware model number or the exact bottle or jar opening/neck dimensions, required material and finish, quantity and, when possible, a drawing or physical sample.

Do not assume an accessory will fit only because the nominal diameter looks similar. Opening geometry, thread or insertion details, tolerances and component construction should be checked on representative samples.
