Pill Container Spring Tab Lid Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pill containers with hinged lids often result in lids becoming deformed and bent when in a closed position, and existing solutions, such as using a resilient pushing bar, are not entirely satisfactory.
Innovation Solution
A container design featuring a base with a molded-in integral spring tab that engages with the lid to pivot it from a closed to an open position, utilizing a hook and catch arrangement for locking and unlocking, and a push button assembly to facilitate easy opening by releasing the spring tab's push against the lid's interior surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional pill container with hinged lid is used, then the container structure is simple, but the lid becomes deformed and bent when in closed position
Solution Approach 1:
The patent introduces a resilient pushing bar that changes the mechanical parameters of the lid system by providing continuous upward force. This force counteracts the downward pressure from the closed lid, preventing deformation while maintaining structural simplicity.
Solution Approach 2:
The resilient pushing bar acts as an intermediary element between the lid and base. It transmits and modifies forces, providing the necessary support to prevent lid deformation without requiring complex structural changes to the lid or base themselves.
2Shape
If a resilient pushing bar is used to prevent lid deformation, then lid shape is maintained, but the device complexity increases
Solution Approach 1:
The patent merges the pushing bar function with the existing lid and base structures. The pushing bar is integrated into the container assembly, combining multiple functions (support, sealing, and structural connection) into a unified design that minimizes additional complexity.
Solution Approach 2:
The resilient pushing bar modifies the force parameters within the container system, providing continuous upward support force that prevents lid deformation. This parameter change approach allows simple structural additions to achieve complex functional requirements.
3Reliability
If the lid is securely locked in closed position, then containment is reliable, but the opening process becomes difficult
Solution Approach 1:
The resilient pushing bar performs preliminary action by continuously applying upward force to the lid throughout the closing process. This pre-applied force reduces the net force required by the user to open the lid, making the opening operation easier while maintaining secure locking during normal use.
Solution Approach 2:
The system provides tactile feedback through the resilient pushing bar, which the user can feel and use as guidance during the opening process. This feedback mechanism helps users understand the locking state and provides a natural opening motion, improving ease of operation while maintaining reliability.
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 design ensures the lid can be easily and reliably opened without deformation, providing a secure closed position and preventing loose parts from entering the container, enhancing user safety and convenience.
Implementation Method 1
a molded in, integral spring tab projecting from an exterior of the back portion... the spring tab being in pushing engagement against the interior surface of the lid, when the lid is in the closed position

AI summary
A pill container includes a base with a cavity and a lid movable between a closed position and an open position. The base has an integral spring tab such that when the lid is unlocked from the base, the spring tab pushes against an interior part of the lid to move the lid from the closed position to the open position.
