Solution Overview

Problem

Conventional shipping and reshipping packagings require external adhesive means, such as tape, for secure resealing, which may not always be available to the user.

Innovation Solution

A packaging design featuring a closure strip with both severable and permanent segments, where the permanent segment remains integral after separation, and is covered with a peelable adhesive protection, allowing for secure resealing without external means.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a closure strip with only severable segments is used, then the packaging can be easily opened, but the packaging cannot be securely resealed without external adhesive means

Engineering Contradiction:

Improveease of openingVSAvoidres sealing capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The closure strip is divided into multiple segments: severable segments that can be broken to open the packaging, and permanent segments that remain attached to provide a surface for adhesive application during resealing. This segmentation allows the closure strip to serve dual functions of easy opening and secure resealing capability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The closure strip is designed to perform multiple functions: it provides initial closure, enables easy opening through severable segments, and facilitates secure resealing through permanent segments with adhesive application surfaces. This multi-functionality eliminates the need for separate adhesive means

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If external adhesive means are required for resealing, then secure closure is achieved, but the packaging becomes dependent on external resources not always available to users

Engineering Contradiction:

Improveclosure securityVSAvoidindependence from external means

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The packaging incorporates all necessary components for secure closure within itself. The permanent segments of the closure strip include integrated adhesive application surfaces and peelable protection layers, allowing the packaging to seal itself without requiring external adhesive tape or other means

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If a closure strip with both severable and permanent segments is used, then secure resealing is enabled, but the closure strip structure becomes more complex

Engineering Contradiction:

Improveres sealing capabilityVSAvoidclosure strip structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the closure strip have different properties: severable segments are designed to be broken, while permanent segments are designed to remain attached and receive adhesive. This local differentiation of properties allows each segment to perform its specific function optimally

Inventive Principle:

Principle #3Local quality

AI summary

The invention relates to a shipping and reshipping packaging unit comprising a packaging body (C) and at least one closure panel (27, 77) and means for maintaining the closure panel (27, 77) in a closed position of the packaging body (C) by adhesion, characterized in that the maintaining means comprise at least one closure strip (B) comprising at least one separable portion (31, 33, 52) connected to the rest of the closure strip (B) and/or to the rest of the packaging unit, namely the body and/or the closure panel (27, 77), by at least one weaker line, and at least one permanent portion (32, 51, 53) that is substantially aligned with the separable portion (31, 33, 52) and remains integral with the rest of the packaging unit after separation of the separable portion (31, 33, 52), the closure strip (B) bearing, on a face, referred to as internal face, intended to be oriented towards the interior of the packaging unit when the latter is closed, at least one rectilinear adhesive strip (40) extending at least partially along the length of the closure strip (B), including over the separable portion (31, 33, 52) and permanent portion (32, 51, 53) and being covered by a protector that is peelable into a plurality of individually peelable portions (41, 42, 42) corresponding at least to the separable and permanent portions of the closure strip (B).
