Tamper-Evident Container With Pivoting Lid And Reclosing Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for consumer articles, such as cigarettes, lack a secure and cost-effective method for reclosing without an inner frame or self-adhesive label, while maintaining tamper evidence and ensuring the product's integrity.
Innovation Solution
A container design featuring a laminar blank with separation lines and a detachable lid that pivots about a hinge line, incorporating an inner front panel with reclosing means like slits or hook-and-loop fasteners to securely re-close the container after opening, eliminating the need for an inner frame or self-adhesive label.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an inner frame or self-adhesive label is used for reclosing, then secure reclosing is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent removes the inner frame and self-adhesive label from the container structure, retaining only the essential box and lid components. The reclosing function is achieved through the lid's distal end engaging with a recess in the box front wall, eliminating unnecessary structural elements while maintaining secure reclosing capability.
Solution Approach 2:
The container structure itself provides the reclosing mechanism through the engagement between the lid's distal end and the recess in the box front wall. This self-contained design eliminates the need for separate reclosing components like inner frames or adhesive labels, allowing the container to service its own reclosing function.
2Reliability
If an inner frame or self-adhesive label is used for reclosing, then secure reclosing is achieved, but manufacturing cost increases
Solution Approach 1:
The patent eliminates the inner frame and self-adhesive label components, reducing the bill of materials and assembly steps. The reclosing function is achieved through the simplified engagement between the lid and box front wall recess, directly reducing manufacturing cost while maintaining functionality.
Solution Approach 2:
The reclosing function is merged into the basic lid and box structure itself, rather than being a separate feature requiring additional components. The distal end of the lid and recess in the box front wall work together as an integrated reclosing mechanism, simplifying manufacturing.
3Reliability
If tamper evidence features are added, then product integrity is protected, but device complexity increases
Solution Approach 1:
The container structure itself provides tamper evidence through the integrity of the separation lines and the engagement mechanism between the lid and box. Any attempt to tamper with the container would visibly disrupt these features, eliminating the need for separate tamper-evident components while maintaining the functionality.

AI summary
A container for consumer articles comprises a box for housing the consumer articles. The box comprises a box front wall, a box back wall and a box top wall. A lid is defined by separation lines in the box front wall and in the box top wall, such that the lid is at least partly separable from the remainder of the box, wherein upon separation from the remainder of the box the lid is pivotable about a hinge line between an open position in which consumer goods can be removed from the container through an access opening of the container and a closed position in which the interior of the container is inaccessible. The container further comprises an inner front panel underlying and attached to at least a portion of the box front wall. The inner front panel is configured to releasably keep the lid in a closed position when the lid has been at least partly separated from the box.
