500ml Diffuser Bottles

Start with the target fragrance fill, bottle stability, opening size and the intended reed system. The bottle should remain stable when the reeds are installed, and the opening should provide enough clearance for the selected reed quantity and diameter without being unnecessarily large.

Then confirm the transport plug or stopper, decorative cap, fragrance compatibility, evaporation rate, decoration and retail packaging on the filled assembled sample. Diffuser performance depends on the bottle, fragrance, reeds and closure working together.

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.

Export packing is selected according to product shape, weight, finish, accessories and shipping method. Common protection includes partitions, molded trays, inner bags or wraps, cartons, corner protection, pallet wrapping and extra separation for decorated surfaces.

Heavy, shaped or protruding products need different protection from simple round containers. Final packing should be approved with the actual product and component set rather than copied from another model.
