Paperboard Wine Container With Adhesive Shell Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional glass wine bottles are heavy, costly to transport, prone to breakage, and have high manufacturing costs, while pulp moulded cardboard bottles with plastic linings have reduced shelf life and difficulties in printing and manufacturing costs.
Innovation Solution
A container design featuring a paperboard outer shell formed from separate flat sheet elements bonded together with a heat-activated adhesive, including a cylindrical main body, neck, and base, with an inner lining and fitment to support a bag, allowing for printing on the outer surface and improved handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glass bottles are used for wine storage, then wine quality is maintained, but weight and transportation costs increase significantly
Solution Approach 1:
The bottle is divided into two separate components: an outer glass bottle for wine storage and an inner paperboard shell for protection and handling. This segmentation allows the glass bottle to maintain wine quality while the paperboard shell reduces overall weight and transportation costs.
Solution Approach 2:
The invention uses a composite structure combining glass and paperboard materials. The glass provides excellent wine storage properties while the paperboard shell offers lightweight protection, creating a hybrid container that optimizes both quality maintenance and weight reduction.
2Reliability
If glass bottles are used, then wine quality is maintained, but breakage risk increases
Solution Approach 1:
The paperboard shell is designed to surround and cushion the glass bottle before any impact occurs. This protective outer layer absorbs shocks and prevents direct contact between the glass bottle and external forces, thereby reducing breakage risk while maintaining wine quality.
Solution Approach 2:
The composite structure of glass inner bottle and paperboard outer shell combines the chemical inertness of glass with the shock-absorbing properties of paperboard, creating a container that maintains wine quality while resisting breakage.
3Weight of moving object
If pulp moulded cardboard bottles with plastic linings are used, then weight is reduced, but shelf life decreases
Solution Approach 1:
The paperboard shell is made from homogeneous food-grade paperboard material without plastic linings, ensuring chemical consistency and avoiding contamination that could reduce shelf life. This homogeneous structure maintains wine quality while keeping the bottle lightweight.
Solution Approach 2:
The paperboard shell is designed as a disposable protective outer layer that can be easily discarded after use, reducing the need for durable but potentially harmful plastic linings. This approach maintains weight reduction benefits while preserving wine shelf life through chemical inertness.
4Weight of moving object
If pulp moulded cardboard bottles are used, then weight is reduced, but manufacturing cost increases
Solution Approach 1:
The manufacturing process is segmented into independent steps: producing the glass bottle, producing the paperboard shell, and assembling them. This segmentation allows each component to be manufactured using optimized, cost-effective processes rather than requiring complex integrated manufacturing.
Solution Approach 2:
The paperboard shell undergoes parameter changes through moisture control and adhesive application processes that optimize its structural properties for protection while maintaining manufacturing simplicity and cost-effectiveness.

AI summary
A container has a paperboard outer shell and an inner lining. The container also has a main body portion, a neck portion providing an opening of the container and a base on which the container may be supported in use. The outer shell has a first side wall element including a part of the neck portion and a part of the main body portion of the container; a second side wall element including a part of the neck portion and a part of the main body portion of the container; and a third base element including the base of the container. The first, second and third elements are separate elements bonded together to form the shell, and are formed from flat sheet material pressed to form the 3-dimensional shape of the shell.
