Tamper Prominent Containers with Button Lock and PCC Image
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tamper-evident packaging solutions, such as tear strips and tear lines, are structurally weak and consumer-unfriendly, making it difficult to ensure product integrity and tamper evidence, particularly in reclosable containers.
Innovation Solution
The introduction of a button locking assembly with prominent continuity control (PCC) images that require a higher force to separate than the perforations, ensuring the PCC image is prominently displayed upon fracture, providing clear visual evidence of tampering and allowing repeated access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If tear strips are used for tamper evidence, then visual inspection capability is improved, but structural strength deteriorates due to weakened hinge areas
Solution Approach 1:
The invention divides the tamper evidence function into separate components: the button locking assembly (providing mechanical strength) and the PCC image (providing visual inspection capability). This segmentation allows each component to optimize its specific function without compromising the other, resolving the contradiction between visual inspection capability and structural strength.
Solution Approach 2:
The PCC image acts as an intermediary between the button locking assembly and the consumer. Instead of relying on the physically weakened tear strip to provide visual evidence, the PCC image prominently displays tamper evidence through optical means, eliminating the need to compromise structural integrity for visual inspection.
2Difficulty of detecting and measuring
If thin tear strips are used for tamper evidence, then visual inspection capability is improved, but ease of operation deteriorates due to difficult gripping and removal
Solution Approach 1:
The PCC image serves as an intermediary that provides visual inspection capability without requiring physical manipulation of thin, difficult-to-grab strips. The button locking assembly with its prominent image allows consumers to visually verify tamper evidence easily, eliminating the operational difficulties associated with traditional tear strips.
3Reliability
If button locking assembly is made strong to prevent tampering, then reliability is improved, but ease of operation deteriorates due to difficulty in separation
Solution Approach 1:
The invention applies local quality by making the button locking assembly strong overall for reliability, but creating localized weak points through perforations that guide the separation process. This allows the assembly to maintain high reliability during normal use while enabling easy separation when needed, resolving the contradiction between reliability and ease of operation.

AI summary
The present invention is directed to containers and packaging that incorporate novel tamper evident features that make prominent the evidence of tamper. In particular, the novel tamper prominent containers of the present invention comprise newly designed tamper prominent images, i.e., prominent continuity control (PCC) images. Additionally, the present invention provides novel methods of increasing prominence of the evidence of tamper with a container, e.g., of consumer goods, by incorporating prominent continuity control (PCC) images integrated with a button locking assembly that must be removed to open a locked container making prominent the evidence of tamper through clear visualization in the PCC image, e.g., prominently displaying an image of a broken lock after full fracture and removal of the button locking assembly.
