Folded Paperboard Container Carrier for Stronger Bottle Batches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging methods for containers using plastic films or straps result in significant waste, energy consumption, and environmental harm, while alternative solutions like cardboard trays or rigid sheets lack strength and ease of handling.
Innovation Solution
A packaging device comprising a rigid or semi-rigid sheet with two parts - a support part with orifices for container necks and a reinforcing part with a foldable opening, allowing easy handling and separation of containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic film is used to wrap containers, then the batch can be held together and handled, but environmental harm increases and energy consumption increases
Solution Approach 1:
The invention changes the material parameter from plastic film to rigid or semi-rigid paperboard, fundamentally altering the environmental characteristics while maintaining the batch holding function through structural design with orifices and reinforcing elements
Solution Approach 2:
The packaging device uses composite construction combining rigid and semi-rigid paperboard materials to achieve both structural strength for holding containers and environmental friendliness, eliminating the need for plastic film while maintaining reliability
2Reliability
If plastic strap is used to surround containers, then the batch can be held together, but additional fastening means are required
Solution Approach 1:
The invention merges the functions of support and reinforcement into a single integrated paperboard sheet structure, eliminating the need for separate plastic straps and additional fastening means while maintaining batch holding capability
Solution Approach 2:
The rigid or semi-rigid sheet performs multiple functions simultaneously: supporting containers through orifices, reinforcing the batch structure through folded parts, and providing handling capability through integrated design, replacing multiple separate components
3Device complexity
If cardboard tray is used to support containers, then additional fastening means are not required, but handling and transport become difficult
Solution Approach 1:
The invention transitions from a flat cardboard tray to a three-dimensional structured sheet with folded reinforcing parts and orifices, creating handling loops and structural features that enable easy grasping and transport while maintaining simplicity
4Ease of operation
If rigid cardboard sheet is used to hold containers, then handling is improved, but batch strength is not guaranteed for large format containers
Solution Approach 1:
The invention uses dynamic structural features including folded reinforcing parts that can adapt to different container sizes and weights, providing adjustable strength while maintaining handling ease through the same basic structure
Solution Approach 2:
The combination of rigid and semi-rigid paperboard materials creates a composite structure that provides enhanced strength for large format containers while retaining the handling advantages of rigid sheet design

AI summary
Described is a device for packaging at least two containers in a batch and methods for packaging containers using the device. The containers can be bottles with a neck. The device includes at least one sheet of semi-rigid or rigid material. The sheet has at least two parts, a first support part with at least two orifices for receiving the necks of the containers, and a second reinforcing part with at least one opening. The sheet has at least one fold line separating the first part and the second part, and the opening is able to cover at least one of the orifices of the support part in a covering folding position of the reinforcing part.
