Description

Tamper Evident Closure Design

A leading company, in collaboration with Desall, is looking for an innovative cap for the personal care, cosmetics, and food sectors, that integrates a safety system capable of visibly indicating first opening or tampering. The cap must incorporate this safety system, using a component that must be removed, broken, or altered in shape in a way that cannot be reversed. This system is used on products that, once opened, may be subject to alteration or are of high value, thereby protecting consumers from unsafe or tampered products. 


To develop an effective and innovative closure for the e-commerce sector, the project should follow these key principles:

- Compatibility: The cap should preferably be compatible with threaded bottle necks and/or press-fit necks.

- Plastic reduction: Minimize non-essential components and optimize the design by reducing thickness without compromising functionality.

- Simplified design: Avoid complex structures that increase costs and make the product harder to use. Develop a system that highlights tampering without completely separating the components.

- Ease of recycling: Use a single component or easily separable parts to improve sustainability.

- Customization: Possibility to add a logo or the customer’s brand name.

- Airtight seal: The cap must ensure an airtight closure.
