Solution Overview

Problem

Existing film containers for pharmaceutical active substances lack effective childproof mechanisms, posing a risk of accidental access by children to potentially toxic medications.

Innovation Solution

Incorporating a releasably fastened sliding element for each accommodating chamber that must be manually actuated to expose the filling area, combined with a tear-off or tear-open tab, to create an additional childproof lock that is difficult for children to open but easily accessible for adults.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional sealed film container is used, then the filling is protected from environmental effects, but children can accidentally access the filling

Engineering Contradiction:
Improvechildproof securityVSAvoidaccessibility for adults
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The closure region is segmented into a sealed edge region and an unsealed removal region, with the latter forming a tab that can be pulled to initiate opening. This segmentation allows the container to remain securely sealed during normal use while enabling deliberate opening by adults who can perform the pulling action.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A physical marking in the form of an incision or line is pre-formed in the closure region, extending from the edge toward the center but not reaching it. This preliminary marking guides the opening action and makes it clear to adults where to apply force, while the incomplete nature of the incision maintains security against accidental opening by children.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the closure region is made broader to form a tab for pulling, then the container can be opened by adults, but the structural integrity may be compromised

Engineering Contradiction:
ImproveopenabilityVSAvoidstructural integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The closure region is divided into a sealed edge region that maintains structural integrity and an unsealed removal region that forms the pullable tab. This segmentation allows the tab to be broadened for easy gripping and pulling without compromising the strength of the main sealed structure that protects the filling.

Inventive Principle:
Principle #1Segmentation

AI summary

A film container includes a bottom film and a top film connected thereto for forming at least one accommodating chamber for a filling, in particular a pharmaceutical active substance formulation. A detachably fastened sliding element which covers the accommodating chamber is assigned to the accommodating chamber as a safeguard.
