Case Study: Custom Wide-Mouth Shampoo Bottles Enhance User Refilling Experience

🧴 Customer Pain Point

An e-commerce client reported an issue where consumers were experiencing frustration when refilling shampoo from large refill packs into traditional narrow-neck bottles. Due to the narrow neck, liquid often spilled out, leading to waste, inconvenience, and negative reviews. This problem was especially prominent in products like shampoos and conditioners, which are thicker and harder to control. Consumers often had to shake the bottle excessively, which resulted in inaccurate pouring. Not only did this affect user experience, but it also led to increased complaints and negative feedback, damaging the brand's reputation and impacting sales.

🛠 PauPack Solution

To address this issue, PauPack developed an innovative solution tailored to the client's needs. We designed a wide-mouth bottle with a spill-preventing, flow-directing spout. This design allowed the liquid to pour out smoothly without the risk of spilling, ensuring a more accurate and controlled pouring experience. In addition, to meet the demand for users to control the amount of liquid being dispensed, we added clear, visible volume markings on the transparent bottle body. This feature made it easy for consumers to monitor the amount of liquid inside, preventing over-pouring and reducing waste.

Furthermore, we also enhanced the bottle's sealing mechanism to ensure no leakage during transportation. By improving the tightness between the bottle and the cap, we ensured that the product remained secure during shipping and storage. We worked closely with the client to optimize the materials of both the bottle and cap to ensure a perfect fit and maximum functionality.

✅ Results

The new bottle design successfully addressed the issues raised by customers and led to a significant improvement in consumer satisfaction. Post-launch data revealed that customer repurchase rates increased significantly, and product reviews improved drastically, with a marked reduction in negative feedback. The most notable outcome was the 65% increase in monthly sales compared to the previous period after the new bottle was introduced. This case demonstrates PauPack's ability to innovate in packaging design and how our customized solutions can create tangible business value and enhance market competitiveness.

Through this case, PauPack showcased our deep understanding of market needs and our ability to respond swiftly to customer pain points. Our design not only solved practical issues but also enhanced the brand's image with thoughtful innovations, helping our client gain a stronger foothold in the market.
