Clamshell Container with Twist Lock for Large Item Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locked bottles can only securely store items that fit through the neck, limiting the size of items that can be securely stored.
Innovation Solution
A clamshell container device with a twist-on combination lock or other locking mechanisms that allows items larger than the neck size to be securely stored by using a hinge and clip wings for a tight seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional locked bottle is used, then security against unauthorized access is provided, but the size of items that can be securely stored is limited to items that fit through the neck
Solution Approach 1:
The closure device is divided into a cap portion and a collar portion that can rotate relative to each other. The collar portion can be independently rotated to unlock while the cap remains on the bottle, allowing the opening mechanism to be separated from the sealing function. This segmentation enables larger items to be accessed while maintaining security through the independent locking collar.
Solution Approach 2:
The collar portion is designed to fit over the neck of the bottle and contain the locking mechanism within its structure. The cap fits over the collar, creating a nested arrangement where the locking function is embedded within the overall closure system. This nesting allows the security mechanism to be integrated without preventing access to larger items.
2Reliability
If a locking mechanism is added to secure the bottle, then unauthorized access is prevented, but the device complexity increases
Solution Approach 1:
The locking function is extracted as a separate collar portion that can be independently rotated and removed. This extraction allows the security mechanism to function independently from the cap, simplifying the overall design by separating the locking function from the sealing function. The collar can be easily manipulated to lock or unlock without requiring complex integrated mechanisms.

AI summary
A container device and lock and method for locking the container device are disclosed. The container device may be a clam shell container which is secured with a twist on closure. This clam shell container allows for storage of items which are larger than the neck size of a twist-on closure. The container device may have wings on the side of the closure to secure a tight fit with a gasket to make the device water and smell resistant. This device can be used to secure items from unauthorized users. Medications are a common item which can be secured within this device.
