Pharmaceutical Container Label with Peelable Window for Visual Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pharmaceutical container labels with light-blocking properties make it difficult to accurately check the contents from the outside due to the formation of light incident parts, such as perforated lines, when a window is created for visual inspection.
Innovation Solution
A two-layer label system where a lower-layer label with light-blocking properties is adhered to the container, and an upper-layer label is peelably stuck to cover a non-adhesion portion, allowing for visual inspection without forming a light incident part, as the upper-layer label peels off integrally with the non-adhesion portion, exposing the window.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a window is formed by cutting a perforated line in a light-blocking label, then visual checking of contents becomes possible, but the cut line becomes a light incident part that allows light to enter
Solution Approach 1:
The patent introduces an upper-layer label as an intermediary component that covers the cut line of the lower-layer label. This upper-layer label acts as a mediator that allows the cut line to exist for window formation while preventing light from entering through it, thus resolving the contradiction between visual checking and light blocking
2Object-affected harmful factors
If a light-blocking label is adhered to the container, then light-blocking property is maintained, but it becomes difficult to accurately check the contents from the outside
Solution Approach 1:
The patent divides the label into two separate layers: a lower-layer label for light-blocking and an upper-layer label for visual checking. This segmentation allows each layer to perform its specific function independently, resolving the contradiction between maintaining light-blocking properties and enabling accurate visual inspection
3Ease of manufacture
If a perforated line is formed in the label for window creation, then the window formation becomes smooth, but the perforated line creates a light incident part
Solution Approach 1:
The upper-layer label serves as a mediator that covers the perforated line created in the lower-layer label. This allows the perforated line to facilitate smooth separation and window formation while the upper-layer label prevents light from entering through the resulting cut line
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
Enables easy visual checking of contents without light entering through the cut line, ensuring accurate monitoring of content state without being affected by the color of the lower-layer label, and maintaining light-blocking properties.
Implementation Method 1
an upper-layer label which is peelably stuck to an outer surface of the lower-layer label so as to cover at least the non-adhesion portion and to adhere to the non-adhesion portion

AI summary
A pharmaceutical container label 1 to be stuck to an outer circumferential surface 12r of a pharmaceutical container 100 having translucency, includes: a lower-layer label 2, having light-blocking property, to be adhered to the outer circumferential surface 12r of the pharmaceutical container 100 so as to form a non-adhesion portion 2B; and an upper-layer label 3 which is peelably stuck to a surface 2a of the lower-layer label 2 so as to adhere to the non-adhesion portion 2B. When the upper-layer label 3 is peeled off, the non-adhesion portion 2B is integrally peeled off, a region covered with the non-adhesion portion 2B is exposed, and the exposed region serves as a window 15 which allows visual checking of the contents.
