Composite Package Arching and Grip Panels for Beverage Cartons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Composite beverage cartons face issues with grip and ergonomics, leading to undesired deformations and uncontrolled pouring during distribution and consumption, despite complex deformation processes that affect dimensional stability and consumer preference for appearance and tactile properties.
Innovation Solution
A composite package design featuring a package base body with positive arching on the front side and grip panels on the rear side, eliminating edge creases for improved grip and ergonomics, along with a package laminate and sleeve blank that facilitate easy production and handling, including a chamfered gable and transverse sealing seam for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If complex deformation processes are used to shape the package, then the package can achieve desired forms and features, but dimensional stability is affected and deformation risks increase during distribution
Solution Approach 1:
Creases are pre-incorporated into the package laminate material during production to predefine package fold lines. This preliminary action allows the material to be folded along predetermined paths during packaging, achieving the desired shape while minimizing unexpected deformations and maintaining dimensional stability during distribution.
2Ease of operation
If traditional package designs with continuous edges are used, then manufacturing is simpler, but grip and ergonomics are poor leading to uncontrolled pouring
Solution Approach 1:
The package front side is segmented into a positive arching portion and a grip panel portion. The positive arching extends over projections defining the front side and passes into lateral package sides, while the grip panel is formed at least in sections in the region of projections defining the package rear side. This segmentation improves grip and ergonomics without significantly complicating manufacturing.
3Ease of operation
If grip panels are added to improve ergonomics, then tactile experience and grip capability are enhanced, but material complexity increases
Solution Approach 1:
The package laminate is designed with different local qualities: the front side features positive arching for structural integrity and aesthetic appeal, while the rear side features grip panels with modified surface properties for enhanced tactile experience and grip capability. This local differentiation optimizes each region for its specific function without requiring complete redesign of the entire package structure.

AI summary
A composite package, in particular a beverage carton package for liquid foodstuffs is depicted and described which consists at least partially of a package laminate, having a package base body including package edges, an at least partially angular package base and package gable wherein the package base body defines, in an idealised manner, a package front side, package rear side and at least two lateral package sides attaching to the package rear side as well as a package laminate and a package sleeve blank for manufacturing such a composite package. In order to improve grip and ergonomy for an easy to manufacture package, provision is made for the package front side to have a positive arching at least in sections which in each case passes into a lateral package side for a grip panel to be formed at least in sections in the region of the package rear side.
