Tube Body Design.

Our soft tube packaging material features a slender design with a standard 19mm tube diameter and a length of 97mm. It is comfortable to hold and allows for agile handling. The tube body undergoes rigorous wall thickness control during injection molding, ensuring that it does not deform or break easily under frequent compression while maintaining an appropriate level of rebound resilience.

• Key Design Feature: The core design features a snap-in mechanism rather than a traditional spiral cap. This design ensures both the tightness of the connection between the brush head and the body and ease of replacement, where the user can simply snap it into place and twist it off.    · Material: The parts that come into direct contact with the user’s mouth are typically made from a harder type of engineering plastic, such as PP or ABS, to ensure the durability and long-term stability of the snap-in mechanism.
• Sealing Mechanism: A miniature sealing ring or sealing lip is integrated within the snap-in mechanism. When the brush head is snapped into place, it creates a well-sealed, airtight space that effectively isolates the air and protects the contents’ activity.
• User Experience: The carefully designed angle and force of the latch mechanism achieve an optimal balance of “ease of locking and unlocking,” allowing users to perform these actions effortlessly without exerting much effort.
• Visual Design: The combination of the “Colored Tube” and the screen printing pattern inspired by “Russian Colorful Matryoshka Dolls” creates a distinct and visually striking appearance on the shelves. The screen printing process ensures both the fine detail and durability of the design. · Potential for Customized Printing: The “Russian Matryoshka” pattern is merely an example. The brand can undertake a comprehensive visual customization based on the product’s positioning.

Product advantages:

1. Reimagining the consumer experience: It transforms the traditional “passive use” into “active interaction and playful engagement,” significantly enhancing the interaction between users and products, thereby boosting the enjoyment and ritualistic aspects of the usage process.
2. Building a brand moat: This innovative packaging format itself serves as a powerful differentiator. Once consumers purchase the brush head system, it creates a “lock-in effect,” making them more likely to prefer products from the same brand or those that are compatible with the system, thereby establishing strong user loyalty.
3. Exploring new revenue streams: The brand can independently sell replacement brush heads, limited-edition brush heads (such as holiday-themed colors or collaborations with artists), or travel kits that include an empty tube paired with various brush heads, thereby creating additional profit centers beyond the main product offerings.
4. Promoting sustainable practices: Unlike “single-use” packaging, the system’s tube base can be reused. Consumers only need to purchase replacement cores (if the brand offers them) and replace the brush heads, which aligns with the current consumer trend towards environmental sustainability and reducing plastic waste. This approach helps the brand project a responsible image.
