Solution Overview

Problem

Existing methods for forming bundles of containers, such as plastic bottles, often result in instability during transport due to nesting issues and require high strapping tension, and existing solutions fail to maintain cohesion after removal of articles without strapping.

Innovation Solution

The solution involves applying adhesive to the contact surfaces of containers, specifically designing them with flattened 'roll-off rings' to prevent nesting and ensuring cohesion through strategically placed adhesive applications, allowing for easy removal and reassembly without strapping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high tension is applied to the strapping to prevent nesting during transport, then the stability of containers during transport is improved, but the device complexity and cost increase

Engineering Contradiction:
Improvestability of containers during transportVSAvoidstrapping tension mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical strapping system with an adhesive bonding system. Instead of using mechanical strapping elements that require high tension to prevent nesting, the invention applies adhesive directly to the contact surfaces of the containers themselves, creating a chemical bonding mechanism that eliminates the need for complex mechanical restraint systems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The containers are designed with self-adhesive contact surfaces that automatically bond when containers are stacked or placed together. The adhesive is applied to the head or foot areas of the containers, allowing them to self-stabilize during transport without requiring external strapping mechanisms or additional tensioning devices.

Inventive Principle:
Principle #25Self-service

2Reliability

If strapping is used to hold articles together in a container, then the cohesion of articles is improved, but the ease of operation deteriorates when articles need to be removed or reassembled

Engineering Contradiction:
Improvecohesion of articlesVSAvoidremoval and reassembly of articles
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical strapping system with an adhesive bonding system. Instead of using mechanical strapping elements that require high tension to prevent nesting, the invention applies adhesive directly to the contact surfaces of the containers themselves, creating a chemical bonding mechanism that eliminates the need for complex mechanical restraint systems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The adhesive contact surfaces are designed to be uniform and consistent across all containers, allowing for standardized bonding behavior. This homogeneity ensures that containers can be easily removed and reassembled while maintaining consistent cohesion, as the adhesive properties are uniform throughout the container population.

Inventive Principle:
Principle #33Homogeneity

3Ease of operation

If adhesive is applied to contact surfaces to maintain cohesion without strapping, then the ease of operation is improved for removal and reassembly, but the strength of bonding may be insufficient under high transport conditions

Engineering Contradiction:
Improveremoval and reassembly of articlesVSAvoidbonding strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The adhesive is applied specifically to the head or foot contact surfaces of the containers, concentrating the bonding strength at the critical interface points where containers make contact. This localized application ensures sufficient bonding strength at the contact points while maintaining ease of operation, as the adhesive only needs to withstand forces at these specific locations rather than throughout the entire container surface.

Inventive Principle:
Principle #3Local quality

AI summary

The invention relates to a pack (2) without a wrapping film, which pack is formed in each case from a group of articles comprising at least two, preferably at least four articles (4) disposed in a non-nesting position, wherein neighbouring articles (4) touch one another in at least one spherically designed contact region (12) of the articles in one or more contact or touching surfaces (13). The contact and touching surfaces (13) of each article interrupt the spherical contact region (12) in the radial direction viewed in the circumferential direction, preferably in a positive manner, wherein at least a part of the contact and touching surfaces (13) and/or a sub-region thereof is provided with an application of adhesive (8).
