Perforated Carton Volume Reduction via Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container designs fail to efficiently reduce volume after partial consumption of contents, leading to space inefficiency during storage.
Innovation Solution
A container with perforations and creases that allow panels to be folded or removed, forming a secondary box after partial consumption, thereby reducing volume and optimizing storage space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the container maintains its original size after partial consumption, then structural integrity is preserved, but storage space efficiency deteriorates
Solution Approach 1:
The container is divided into multiple removable sections separated by perforations. Users can tear off used portions along the perforated lines, segmenting the container into smaller units that match the remaining content volume, thereby improving storage space efficiency without compromising the integrity of the remaining section.
Solution Approach 2:
The container transitions from a static fixed-volume structure to a dynamic variable-volume structure through foldable panels and removable sections. The container can be reconfigured or reduced in size according to the amount of content remaining, allowing the volume to adapt dynamically to usage levels.
2Volume of stationary object
If perforations and creases are added to enable volume reduction, then storage space efficiency improves, but device complexity increases
Solution Approach 1:
The container structure is segmented into standardized sections separated by perforations. This segmentation allows for simple tear-off operations without requiring complex mechanisms, maintaining ease of use while enabling volume reduction. The creases and folds are strategically placed to create natural separation points.
Solution Approach 2:
The container is designed with disposable sections that can be easily torn off and discarded. The perforated sections act as pre-defined failure points that allow users to remove used portions without affecting the remaining container structure, effectively implementing a disposable-section strategy to reduce overall container volume.
3Adaptability or versatility
If panels are made foldable and removable, then adaptability to content levels improves, but manufacturing precision requirements increase
Solution Approach 1:
The perforations and creases are pre-formed during manufacturing at precise locations to guide user actions. The fold lines are pre-creased to ensure accurate folding positions, and perforations are pre-punched to define exact tear-off points. This preliminary preparation of structural features ensures that users can achieve the desired volume reduction without requiring high precision during the actual usage phase.
Solution Approach 2:
The container is divided into discrete segments with clearly defined boundaries through perforations and creases. This segmentation creates modular units that can be independently manipulated, allowing the container to adapt to various content levels by removing whole segments rather than requiring precise partial modifications.

AI summary
The present invention relates generally to a container or a carton having a plurality of selectable volumes. The present invention is also directed to a container having a plurality of identified markings to reduce container volume upon partial consumption of content. The container includes a plurality of fold facilitating creases adapted to allow panels to be folded or removed alone a fold facilitating crease and/or perforation. At least one set of perforations or identified creases are provided in the box so as to form a shell and a second or a secondary box, where the shell is removed after the contents of the box have been partially consumed and space becomes available. The container may further include perforations, flaps, tabs, slits, indentations, notches, along or at an edge of the panel. A blank of bendable and creaseable material for forming a predefined selectable volume carton box is also disclosed.
