Concealed Tearable Strip for Secure Prize Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plastic packaging films with tearable strips for prizes, bonus points, and discounts are easily damaged during transportation and can be exposed, leading to disputes and increased packaging costs due to the need for complex ink printing and special coatings to keep the contents secret.
Innovation Solution
A plastic film with a concealed tearable strip design, where a first tearable strip on the outside is torn to reveal a second strip on the inside, which contains prize information, allowing for secure and cost-effective packaging by integrating the strips within the film body using adhesive bonding or other methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If tearable strips are directly attached to the outside surface of the packaging film, then the prize information is exposed and easily peeped, but the packaging process remains simple
Solution Approach 1:
The patent applies nesting by placing the second tearable strip containing prize information inside the first tearable strip. The second strip is concealed within the hollow portion of the first strip, creating a nested structure that protects the prize information while maintaining a relatively simple overall packaging structure.
Solution Approach 2:
The patent divides the tearable strip into two separate functional parts: the first tearable strip that serves as the outer protective layer, and the second tearable strip that contains the prize information. This segmentation allows the prize information to be hidden while still enabling the tearing function.
2Reliability
If tearable strips are exposed on the outside surface, then they are easily damaged during transportation or handling, but the packaging process remains simple
Solution Approach 1:
The second tearable strip is nested inside the hollow portion of the first tearable strip, providing physical protection against damage during transportation and handling. The outer first strip acts as a protective shell for the inner prize-containing strip.
Solution Approach 2:
The patent provides beforehand protection by designing the first tearable strip to enclose and protect the second tearable strip before any damage can occur during transportation or handling.
3Loss of information
If confidential printing or anti-fouling measures are applied to the plastic film, then prize information confidentiality is improved, but the packaging cost significantly increases
Solution Approach 1:
The patent uses ordinary plastic film material without expensive confidential printing or anti-fouling coatings. The confidentiality is achieved through the structural design of nested tearable strips rather than through costly material treatments or special inks.
Solution Approach 2:
The patent creates a structural copy or model where the first tearable strip replicates the protective function that would otherwise require expensive confidential printing or anti-fouling measures, but achieves the same goal through simple structural design.
4Loss of information
If complicated ink printing and special coating processes are used, then confidentiality is improved, but the packaging process becomes complicated and costly
Solution Approach 1:
The patent achieves confidentiality using ordinary plastic film without complicated ink printing or special coating processes. The solution relies on the simple structural arrangement of nested tearable strips made from常规 materials.
Solution Approach 2:
The patent replaces complicated printing and coating processes with a structural solution where the nested arrangement of tearable strips provides the same confidentiality function through geometric design rather than chemical or optical means.

AI summary
Disclosed is a plastic film with concealed tearable strip, which includes a film body; at least one first tearable strip having two sides respectively forming first and second joint sections; and at least one second tearable strip having two sides respectively forming a third joint section and an internal tear line. The first and second tearable strips each have one side connected to the film body. The first joint section has two sides each forming a tear line. The third joint section has one side forming at least one tear line. The third joint section and the internal tear line have inside faces respectively coupled to the first and second joint sections, whereby the first and second tearable strips are respectively located at outside and inside of the film body and the second tearable strip is concealed at the inside of the film body.
