Packaging Arrangement with Perforated Opening and Latched Distal Strips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper boxes for packaging ink cartridges are complex to build and open, and they lack a reliable method to indicate if the box has been previously opened, often requiring glue to secure the lid, which complicates the construction and can interfere with the product inside.
Innovation Solution
A packaging arrangement featuring a box with a single paper board that folds into a hexahedron shape, using perforated lines and distal strips to create openings that can be covered without glue, allowing easy assembly and recognition of previous opening through latched distal strips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If upper-side panel 134 is glued on bonding surface 140 to form double-layered lid 147, then the lid is reinforced and the box can be opened without breaking other portions, but the building process becomes complicated
Solution Approach 1:
The lid is divided into two separate layers: upper-side panel 134 and bonding surface 140, which are glued together to form a double-layered structure. This segmentation allows each layer to perform its function independently while providing reinforcement without requiring a completely different design approach
Solution Approach 2:
Upper-side panel 134 and bonding surface 140 are merged through gluing to create a unified double-layered lid structure. This combining of separate elements provides the necessary strength while maintaining the modular construction approach
2Reliability
If right-side panel 133 is glued on right-side folding panel 139 and left-side panel 132 is glued on left-side folding panel 138, then the openings are covered, but the building process becomes complicated
Solution Approach 1:
The side panels (right-side panel 133 and left-side panel 132) are segmented from the folding panels (right-side folding panel 139 and left-side folding panel 138), allowing them to be separately constructed and then joined through gluing to cover the openings reliably
Solution Approach 2:
The side panels are prepared and glued to the folding panels in advance during the building process, ensuring that the openings are properly covered before the box is put into service, rather than requiring field assembly or adjustment
3Ease of operation
If hanging panel 143 is inserted into cut 142 to close the upper face, then the box can be closed again, but it is difficult to recognize that the box has been previously opened
Solution Approach 1:
The perforated line 145 is positioned and configured so that when the box is opened, the line breaks in a specific pattern that creates a visible indication. The breaking of this perforated line serves as a permanent marker that the box has been opened, similar to a color or state change that preserves information
4Ease of operation
If push-in area 141 is pushed into the interior to open the box, then the back panel breaks along perforated line 144, but the process is complex and time-consuming
Solution Approach 1:
Perforated line 144 is pre-formed in the back panel 136 at the exact location where breaking is needed for opening. This preliminary preparation allows the box to be opened quickly by simply pushing the perforated line, rather than requiring complex tools or procedures, significantly reducing opening time
Solution Approach 2:
The perforated line 144 is extracted as a separate feature from the main back panel structure, allowing it to break independently when force is applied to push-in area 141. This extraction enables the opening function to be performed separately from the main panel, simplifying the opening process

AI summary
A receptacle includes a first panel, a second panel opposite the first panel, and a third panel contiguous with the first and second panels on different sides. An opening is formed between a first side of the first panel and a second side of the second panel. A lid covers the opening. A first portion of the lid is contiguous with the first side of the first panel and with a second portion of the lid that folds into an interior of the receptacle. One of the first and second panels has a perforation extending from a first end of the second side of the one of the first and second panels to a second end of the second side of the one of the first and second panels. A portion of the perforation is positioned away from the second side of the one of the first and second panels.
