Two-Piece Closure With Removable Liner For Custom Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure systems for containers, such as pharmaceutical containers, are limited in their ability to display custom messages after manufacture, making it difficult to convey time-sensitive information or updates, as messages must be selected and applied during manufacturing, preventing the use of efficient and timely information display.
Innovation Solution
A two-piece closure system comprising a transparent inner cap and an opaque outer cover, with a removable liner that can be inserted to display custom messages, allowing for selection and insertion of different liners based on desired information, such as dosage or promotional messages, post-manufacture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If messages are molded or imprinted directly into the closure during manufacturing, then the message is permanently applied to the closure, but the closure cannot display time-sensitive or custom information after manufacture
Solution Approach 1:
The closure is divided into separate components: a base closure and a removable liner. The liner can be detached and replaced with different liners containing different messages, allowing the closure to display custom or time-sensitive information without changing the base closure structure. This segmentation enables adaptability while maintaining simplicity of the main closure body.
Solution Approach 2:
The liner is designed to be removable and replaceable, transforming the static message display into a dynamic system. Different liners can be inserted depending on the required message, enabling the closure to adapt to different time-sensitive information needs while keeping the base closure simple and unchanged.
2Productivity
If messages are selected and applied during closure manufacturing, then efficient production is achieved, but pharmacies cannot update messages after receiving closures
Solution Approach 1:
By separating the message-bearing liner from the base closure, the manufacturing process can efficiently produce standardized base closures in bulk, while the custom liners are prepared separately and attached later. This allows pharmacies to receive closures ready for use and update messages by simply replacing liners, maintaining both manufacturing efficiency and post-manufacture adaptability.
Solution Approach 2:
The base closure is prepared in advance with the liner attachment mechanism pre-formed, but the specific message liner is left to be selected and attached later at the pharmacy. This preliminary preparation of the closure structure enables efficient manufacturing while preserving the ability to customize messages at the point of use.
3Duration of action of stationary object
If generic messages are used on closures, then closures can be used for a significant amount of time without replacement, but time-sensitive information cannot be displayed
Solution Approach 1:
The liner is designed as a disposable or replaceable component that can be discarded after use and replaced with a new liner containing updated information. This allows the pharmacy to maintain closures for extended periods by simply replacing the informational liners when messages become outdated, preserving both usage duration and information relevance.
Solution Approach 2:
The removable liner creates a dynamic system where the informational component can be updated independently of the structural closure. This allows pharmacies to extend closure usage by replacing liners with current information, preventing information loss while maintaining the physical closure for long-term use.

AI summary
A closure system including a transparent inner cap, an opaque outer cover, and a liner. The transparent inner cap includes a top wall, an open bottom, a sidewall, and an inner cap attaching mechanism disposed on an exterior surface of the sidewall. The opaque outer cover includes an open top, an open bottom, a sidewall, and an outer cover attaching mechanism disposed on an interior surface of the sidewall. The opaque outer cover is dimensioned and configured to be assembled with the transparent inner cap via the corresponding attaching mechanisms to form an assembled two-piece closure with the opaque outer cover substantially covering the sidewall of the transparent inner cap. The liner is operable to be inserted into the two-piece closure such that the liner is visible through the open top of the opaque outer cover and the top wall of the transparent inner cap.
