AI Technical Summary

Technical Problem

Existing packaging assemblies for products like cosmetics cannot be stored in an inverted position without using a significant amount of material, and there is a need for eco-friendly solutions that reduce material usage and waste while ensuring stability and preventing water accumulation.

Method used

A sealing device with a cylindrical mounting skirt and an obliquely extending outer skirt, featuring a larger diameter at the upper end, which provides stability in an inverted position, reduces material usage, and includes design features like openwork structures and stability studs to enhance stability and prevent water accumulation.

Benefits of technology

The solution ensures good stability in inverted storage positions while minimizing plastic material use, reducing environmental impact, and preventing water retention, thus optimizing packaging for transport and disposal.

Abstract

A sealing element (20) for a product packaging and dispensing assembly (1), particularly for cosmetics, comprising a container (10) having an opening and defining an internal volume for receiving the product, the sealing element (20) comprising a mounting skirt (22) axially delimited by an open lower end and a radial upper wall (24) provided with a dispensing orifice (25) and comprising removable fastening means (22b) configured to cooperate with the neck of the container (10). The sealing element (20) comprises an outer skirt (27) radially surrounding the mounting skirt (22) and extending axially obliquely at a non-zero angle (α1) from a lower end connected to the mounting skirt (22) to an upper end (27b) extending axially beyond the radial upper wall (24).
