Blister Pack Peelable Label for Information and Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blister packs for pharmaceutical products face challenges in providing adequate space for branding, safety information, and tamper resistance, with the closure layer being prone to damage during transit or use, and separate information inserts being cumbersome and easily misplaced.
Innovation Solution
A peelable label with a permanently secured and releasably adhered design is applied to the closure layer, allowing additional information to be printed on both sides and providing protection to the closure layer, reducing the need for separate inserts and minimizing the risk of label detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a separate information insert is provided with the blister pack, then product information and safety information can be provided, but the information insert is cumbersome and easily misplaced
Solution Approach 1:
The patent merges the separate information insert with the closure layer by printing information directly on the closure layer. This integration eliminates the need for a separate paper leaflet, preventing it from being misplaced while reducing packaging complexity. The closure layer serves dual purposes: sealing the product and conveying information.
2Loss of information
If printed text is provided on the closure layer, then branding and product information can be provided, but there is limited space for printing
Solution Approach 1:
The patent utilizes the three-dimensional surface of the closure layer, including curved and folded surfaces, for printing information. By wrapping the information around the closure layer and utilizing multiple faces and surfaces, the effective printing area is significantly increased beyond what would be available on a flat two-dimensional surface.
3Ease of operation
If the closure layer is made brittle to allow product dispensing, then the product can be easily pushed through, but the closure layer is liable to damage during transit or use
Solution Approach 1:
The patent modifies the physical parameters of the closure layer by incorporating a hinge that creates a localized flexible zone. This allows the closure layer to maintain overall brittleness for product dispensing while having a specific region with altered mechanical properties that provides flexibility and damage resistance during handling and transit.
4Reliability
If the closure layer is made resistant to damage, then the closure layer integrity is maintained, but the product becomes difficult to dispense
Solution Approach 1:
The patent segments the closure layer into distinct functional zones: a rigid sealing portion that maintains integrity and protects the product, and a flexible hinge portion that enables easy product dispensing. This segmentation allows each zone to optimize its properties for its specific function without compromising the other.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The peelable label effectively provides essential information while maintaining closure layer integrity, ensuring product safety and usability, and can be reattached after use, reducing the likelihood of misplacement and damage.
Implementation Method 1
the peelable label comprises a laminate having a lower layer and an upper layer wherein the peelable label comprises a cut in the lower layer substantially in register with the junction between the first portion and the second portion, wherein the first portion of the peelable label is permanently secured to the closure layer or the panel, and the second portion of the peelable label is releasably adhered to the closure layer

AI summary
There is disclosed a container (100) comprising: a panel (102) which defines one or more pockets (104) in the surface thereof, wherein the one or more pockets (104) are for holding a product (130); a closure layer (106) disposed on the panel (102) for sealing the product (130) in the pockets (104); and a peelable label (108) disposed on the closure layer (106). The peelable label has a first portion (110) and a second portion (112), wherein the first portion (110) of the peelable label (108) is permanently secured to the closure layer (106) or the panel (102), and the second portion (112) of the peelable label (108) is releasably adhered to the closure layer (106).
