Sliding Casing Package for Consumer Goods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Confectionery and tobacco products face challenges in preserving aroma and moisture due to the need for reduced plastic usage in packaging, as existing solutions do not effectively minimize plastic consumption while maintaining product characteristics.
Innovation Solution
A package with a sliding opening design utilizing a tub-shaped container, a repositionable closing label, and a slidingly coupled casing made from wrapping materials like paper or cardboard, which minimizes plastic usage while maintaining the product's aroma and moisture levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic boxes are used to store consumer goods, then the aroma and moisture of the products are preserved, but the quantity of plastic used increases
Solution Approach 1:
The package is divided into two separate components: a container made of plastic that preserves product characteristics, and a casing made of paper or cardboard that provides structural support and sliding opening functionality. This segmentation allows each material to be used only where necessary, reducing overall plastic consumption while maintaining preservation capabilities.
Solution Approach 2:
The invention extracts the essential preservation function from the entire package structure and assigns it specifically to the container component, while the casing component is designed to be plastic-free. This extraction allows the plastic material to be confined to only the portion needed for preservation, minimizing total plastic usage.
2Ease of operation
If a sliding opening package is used, then access to consumer goods is facilitated, but the structural complexity increases
Solution Approach 1:
The package incorporates a sliding opening mechanism where the casing can move relative to the container along a sliding direction. This dynamic feature allows easy access to consumer goods by simply sliding the casing, while the simple linear sliding motion keeps the mechanical complexity low compared to other opening mechanisms.
Solution Approach 2:
The sliding opening mechanism is achieved by separating the casing and container as independent components that slide relative to each other. This segmentation simplifies the overall structure compared to integrated designs, as each component can be manufactured separately and assembled through simple sliding engagement.

AI summary
Package (1) with a sliding opening for consumer goods comprising: a group of consumer goods; a container (2) that is tub-shaped, which contains the group of consumer goods and comprises an extraction opening (20) for the extraction of consumer goods; a closing label (3), which is fixed in a repositionable manner to the first container (2) to open and close the extraction opening (20); a covering (4) of the first container (2), which is made starting from a blank of wrapping material; a casing (5) made starting from a blank of wrapping material. The casing (5) is arranged externally to the covering (4) and is slidingly coupled to the covering (4) to be movable between a closing position (A), in which access to the group of consumer goods is not allowed, and an opening position (B), in which access to the group of consumer goods is allowed.
