Solution Overview

Problem

Existing packaging for brush products often relies heavily on plastic materials, lacking sustainability and tamper-proof features while providing a poor unpacking experience.

Innovation Solution

A paper-based packaging system comprising a tray-like body with a lid element, featuring tear-open elements that ensure tamper-proof integrity and a pleasant unpacking experience, using materials like cardboard or corrugated cardboard with optional plastic coatings below 50% weight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If plastic material is used for packaging, then packaging strength and sealability are improved, but sustainability and environmental friendliness deteriorate

Engineering Contradiction:
Improvepackaging strengthVSAvoidenvironmental harm
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameter from plastic to paper-based material, achieving sustainability while maintaining packaging functionality through optimized paper board structure and design

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite paper-based structures with multiple layers and components (tray-like body, lid element, tear-open elements) to achieve the strength and functionality previously provided by plastic materials

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If traditional paper-based packaging is used, then sustainability is improved, but tamper-proof capability deteriorates

Engineering Contradiction:
Improveenvironmental harmVSAvoidtamper-proof capability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The lid element is segmented into tear-open elements that can be separated from the main body, creating visible separation evidence that indicates whether the packaging has been tampered with

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tear-open elements are pre-configured in a sealed state during manufacturing, providing inherent tamper-evident functionality before the product reaches the consumer

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If traditional packaging is used, then manufacturing simplicity is improved, but consumer experience deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidunpacking experience
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The packaging is divided into modular components (tray-like body, lid element, tear-open elements) that can be easily assembled and disassembled, improving both manufacturing efficiency and consumer unpacking experience

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tear-open elements are pre-configured with tear lines or separation features that guide the consumer through an easy and satisfying opening process

Inventive Principle:
Principle #10Preliminary action

AI summary

The present application is concerned with a paper-based packaging (1A) for at least one brush product and optionally at least one brush product accessory, the packaging having a tray-like body (10) for receiving the at least one brush product and optionally the at least one brush product accessory in at least one receptacle (19) formed by the tray-like body, the tray-like body having a bottom wall (15) and four side walls (11, 12, 13, 14) essentially perpendicularly extending from the bottom wall, a lid element (20A) essentially gap-free fitting over the tray-like body, the lid element having a top wall (21) and four side walls (22A, 23A, 24A, 25A) essentially perpendicularly extending from the top wall, where at least two oppositely arranged side walls of the lid element comprise portions that are secured at respective opposite side walls of the tray-like body, where each of the two oppositely arranged side walls of the lid element comprise at least one tear-open element (24A, 25A), where either the tear-open elements are the portions glued to the side walls of the tray-like body or the tear-open elements are arranged between the portions secured to the opposite side walls of the tray-like body and the top wall, so that in case the tear-open elements are torn open, the remaining portion of the lid element can be removed from the tray-like body.
