Tamper-Resistant Container Closure Using Cohesive Adhesive Seals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food and consumable liquid packaging systems lack tamper-resistant features, leading to concerns about the integrity and accuracy of contents during handling and delivery, with potential loss or tampering of receipts and packaging.
Innovation Solution
A tamper-resistant container system using adhesives, such as self-seal or pressure-seal cohesive materials, to create a permanent seal that cannot be broken without damaging the container, providing visual evidence of tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional packaging without tamper-resistant features is used, then the packaging system is simple and easy to manufacture, but the integrity and security of contents cannot be ensured during handling and delivery
Solution Approach 1:
The adhesive seal is applied in advance to the container closure before the container is filled and sealed. This preliminary application of the adhesive creates a pre-positioned tamper-resistant mechanism that activates when the container is properly closed, providing reliability without adding complex assembly steps during the filling process.
Solution Approach 2:
An adhesive-bearing strip or label acts as an intermediary element between the container body and closure. This intermediary component provides the tamper-resistant function by creating a bond that must be broken to access contents, thereby ensuring integrity while keeping the overall system relatively simple through the use of a separate, specialized component.
2Reliability
If adhesive seals are applied to create permanent seals, then tamper evidence is provided, but the manufacturing process becomes more complex with additional deposition steps
Solution Approach 1:
The adhesive is deposited on a separate strip or label in advance, before the final container assembly. This allows the adhesive application to be performed as a preliminary step in label production rather than as a complex step in container sealing, thereby maintaining tamper resistance while simplifying the overall manufacturing process.
Solution Approach 2:
The adhesive-bearing component is segmented as a separate strip or label that can be independently manufactured and then applied to the container. This segmentation allows the adhesive deposition process to be optimized separately from the container manufacturing, improving ease of manufacture while maintaining reliable tamper evidence.
3Loss of information
If receipts are attached to packaging, then proof of purchase is provided, but the receipts may become lost, detached, or separated from the food packaging
Solution Approach 1:
The receipt is merged with the adhesive-bearing strip or label, combining the purchase proof function with the tamper-resistant sealing function. This merging ensures that the receipt remains attached to the packaging throughout the supply chain, preventing loss or detachment while avoiding the need for separate attachment mechanisms.
Solution Approach 2:
The adhesive-bearing strip serves multiple functions: it provides tamper-resistant sealing, attaches the receipt to the packaging, and can provide structural support for the closure. This multi-functionality reduces device complexity by eliminating the need for separate components for each function.

Function Achieved in This Case
The system ensures the integrity of the contents by preventing unauthorized opening and provides clear visual evidence of tampering, enhancing customer trust and satisfaction.
Implementation Method 1
an adhesive deposited at predetermined locations on the upper portion of the container, wherein the adhesive is either a self-seal cohesive material or a pressure-seal cohesive material, and wherein the adhesive is positioned to adhere to itself when the upper portion of the container is closed

AI summary
A method for making a tamper-resistant container, comprising depositing a first adhesive on a container, wherein the container includes a closed lower portion, a middle portion adapted for storing contents, and a closeable upper portion, wherein the first adhesive is deposited at a predetermined location on an exterior surface of a first panel of the container; folding the closeable upper portion a first time; and subsequent to folding the closeable upper portion the first time, folding the closeable upper portion at least a second time such that the first adhesive contacts a second panel of the container, thereby securely sealing the container in a tamper-resistant manner.
