Pressure-Release Closure for Child-Safe Paper Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions fail to prevent children under a certain age from opening toxic or easily swallowed materials, and materials like paper-based packaging face challenges in meeting mechanical strength requirements while being user-friendly and environmentally friendly.
Innovation Solution
A packaging design with a closure that can be released by pressure applied to specific areas of the outer surface, using paper materials like corrugated cardboard, where the closure is made to be rotationally or laterally displaceable, and incorporates a latching element with a recess system that ensures secure opening only with adult-sized pressure, featuring a tab and groove mechanism for reliable operation and invisible recesses for design simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If small pins are used to latch into holes in the closure to prevent child opening, then child safety is improved, but the device complexity and difficulty of daily use increase
Solution Approach 1:
The invention extracts the visible pin mechanism from the closure structure and replaces it with a pressure-sensitive release system integrated into the container wall. The release means consists of a pressing surface on the container wall that, when pressed with sufficient force, directly moves the closure without requiring separate visible pins or complex latching mechanisms.
Solution Approach 2:
The closure system is designed to be self-actuating through pressure applied to the container wall. The release means includes a pressing surface that, when subjected to sufficient force, directly translates this pressure into closure movement, eliminating the need for separate actuating mechanisms or visible pins.
2Object-generated harmful factors
If paper materials like corrugated cardboard are used for the container, then environmental friendliness is improved, but the mechanical strength and edge strength deteriorate
Solution Approach 1:
The invention employs composite construction by integrating the release means directly into the paper container wall structure. The release means includes a pressing surface formed from the container wall material itself, creating a integrated paper-based system that maintains structural integrity while enabling the pressure-release function.
3Ease of operation
If the closure is made rotationally displaceable to uncover the opening, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
Instead of rotating the closure to open it, the invention inverts the approach by having the closure move laterally in the direction of the opening. The release means, when pressed, directly moves the closure laterally to uncover the opening, simplifying the mechanism while maintaining ease of operation.

AI summary
A packaging comprising a container having a first surface in which an opening is arranged, wherein a closure is arranged below the first surface which is displaceable relative to the opening in order to open the opening, has a release means which releases the closure when pressure is applied to a surface of the container outside the opening.
