Histórico do cliente
Mosteb received a request from a fragrance research company in Lyon, France to design a bespoke decorative diffuser bottle. The institute required 200 ml clear glass bottles which were visually neat but professional enough to be evaluated for fragrance formulation testing and for client purposes.
The specified bottle had to be cylindrical in shape with thin vertical etched lines, stoppered with natural wood and could be used with standard wood reed diffusers. Consistent surface treatment and dimensional stability were also required for the project as the bottles would be reused in testing environments. They selected Mosteb due to our level of customization at the factory level, technical efficiency of communication, and experience in supporting applications of professional fragrances as opposed to retail application.

Desafios
- Acabamentos superficiais de má qualidade utilizados no passado: O instituto já havia colaborado com outros vendedores de frascos difusores decorativos, embora os tratamentos de superfície variassem significativamente entre os lotes. A corrosão desproporcional afetou a consistência visual em sessões de testes comparativos, além de diminuir a confiança na entrega de amostras a parceiros externos.
- Functional Issues During Extended Testing: There were also cases of an unstable base, and non-uniform tolerances of necks in some of the diffuser bottles causing the stopper and reeds to sit inconsistently and have different evaporation rates during prolonged testing.

Análise de Causa
| Issue | Likely Cause | Corrective Action |
| Uneven etched appearance | Inconsistent processing parameters | Standardized etching process |
| Reed instability | Neck dimensional variation | Improved neck mold control |
| Bottle movement | Insufficient base stability | Adjusted base structure |
| Batch variation | Lack of pre-production approval | Added sample and QC approval |


Solução
- Tempo de processamento fixo e processos de corrosão em profundidade com padronização.
- Definições de molde aprimoradas para manter o mesmo pescoço, na vertical.
- Adicione um pouco de espessura à base para aumentar a estabilidade na superfície de trabalho do laboratório.
- Fornecemos amostras de pré-produção e informações completas de controle de qualidade para aprovação antes da fabricação em larga escala.
Resultado
The final bottles had a more uniform etched look throughout the batch. The new neck size also helped to ensure that the stopper and reeds will remain in place during testing and the strengthened base for improved stability on laboratory work surfaces. After this project, the institute affirmed continuous relationship with Mosteb on future diffuser bottle customization programs.
