Packaging Device Depression Zone Lid Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic packaging devices are prone to accidental opening during storage or transport due to their design, which can lead to uncontrolled opening, and existing solutions either complicate user access or result in a non-compact, aesthetically unappealing shape.
Innovation Solution
A packaging device with a container featuring a depression zone on its shoulder that allows easy access to the lid's free edge for actuation, eliminating outward projections and incorporating a hinge system with an elastic hinge for easy opening, while maintaining a compact and ergonomic design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connection between the lid and the base is reinforced to prevent accidental opening, then reliability is improved, but ease of operation deteriorates due to difficulty in opening particularly on first opening
Solution Approach 1:
The opening mechanism is segmented into two functional zones: a reinforced connection zone (base-lid hinge) that provides security against accidental opening, and an accessible actuation zone (depression zone on the container shoulder) that enables easy user opening. This segmentation allows different parts of the system to have different functional characteristics - security where needed and ease of operation where needed.
Solution Approach 2:
The depression zone acts as an intermediary element between the user's finger and the lid-opening function. Instead of requiring direct access to the lid or a complex opening mechanism, the depression zone serves as a mediator that transmits the user's opening action to the lid through the reinforced connection, enabling easy operation while maintaining security.
2Ease of operation
If a tab projects outwards from the lid to allow easy opening, then ease of operation is improved, but reliability deteriorates due to risk of accidental opening during storage and transport
Solution Approach 1:
Instead of projecting a tab outwards from the lid (conventional approach), the invention inverts the approach by creating a depression zone inwards into the container shoulder. This inversion allows the user's finger to access the lid through the depression zone without any outward projections, thereby maintaining ease of operation while eliminating the risk of accidental opening during storage and transport.
Solution Approach 2:
The depression zone is nested within the container shoulder structure, creating a recessed space that accommodates the user's finger while keeping the overall device compact. This nesting approach allows the opening mechanism to be integrated within the container structure rather than adding external projections, maintaining security while enabling easy operation.
3Shape
If the height of the cap is reduced to create a compact shape, then aesthetic appearance and material usage are improved, but ease of operation deteriorates due to difficulty in accessing the opening mechanism
Solution Approach 1:
The invention moves the opening mechanism access from a horizontal direction (outward projections on the lid) to a vertical dimension (depression zone in the container shoulder). This dimensional change allows the user to access the opening mechanism from below through the depression zone, enabling easy operation while maintaining a compact overall height. The depression zone creates a vertical pathway for finger access without requiring outward projections that would increase the horizontal footprint.

AI summary
The invention relates to a packaging device having a container (10) comprising an end wall (11), a side wall (12) extending from the end wall (11), the upper portion of the side wall forming a shoulder (13), a neck (14), defining an opening (15) of axis X, extending from the shoulder (13), and a dispensing head (2) intended to be mounted on the container, the dispensing head (2) comprising: - a base (20) comprising a transverse wall (21) provided with a dispensing orifice (2), an external skirt (23) extending from the peripheral edge of the transverse wall (21) and a fastening means (24), and - a lid (30) hinged to the base (20) about a pivot of axis Y perpendicular to the axis X having a free lower edge (321) which faces the shoulder (13) of the container (10) in the closed position. According to the invention, a depression zone (16) formed in the region of the shoulder (13) of the container (10) leaves a part (322) of the free edge of the lid accessible so as to allow the lid (30) to be pivoted by actuation of the part (322) of the free edge that is accessible from the depression zone (16).
