Hinged Dental Package Assembly with Lever Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dentists face challenges in performing manual operations in the dental field due to the need to handle substances and packages with one hand, requiring a device that can be easily opened and closed with one hand while allowing safe storage and mixing of multiple components without exposure to air or light.
Innovation Solution
A package assembly featuring a container with a hinge mechanism and lever system that allows single-handed operation, including a breakable seal for airtight and tamper-evident closure, and optional features like a mixing cavity and applicator attachment for efficient dispensing and mixing of dental substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional package with separate lid and base is used, then the substance can be stored, but the dentist must use one hand to hold the package and another hand to operate the instrument, reducing operational efficiency
Solution Approach 1:
The lid and base are connected by a hinge mechanism to form an integrated package assembly, allowing the dentist to hold and operate the entire package with one hand while using the other hand for dental instruments, thereby resolving the contradiction between ease of operation and productivity
2Ease of operation
If the package is opened for dispensing, then the substance can be delivered, but the substance becomes exposed to air and light, compromising stability
Solution Approach 1:
The package is pre-filled and sealed with a breakable seal before use, maintaining substance stability during storage and transport. The seal breaks only when needed for dispensing, allowing the substance to be delivered while minimizing exposure time to air and light, thus resolving the contradiction between ease of operation and reliability
3Reliability
If multiple substances are stored separately, then contamination is prevented, but the dentist must manually handle multiple containers, increasing complexity
Solution Approach 1:
Multiple separate containers are nested within a single integrated package assembly, each maintaining its own seal for contamination prevention. The hinge mechanism allows the entire assembly to be held and operated as one unit, reducing the number of separate containers the dentist must handle and resolving the contradiction between reliability and device complexity

AI summary
The present invention is directed to a package assembly for placing it on a surface and for storing and/or delivering substances, preferably dental substances, comprising: at least one container with at least one base and at least one lid; and at least one hinge connecting the base and the lid; wherein the base and the lid comprise at least a first and second lever; the first and second levers are provided at the container essentially on the side of the hinge and; a projection of the first lever onto the surface and the second lever extend with their free ends essentially in a direction away from the hinge; and wherein the container can be opened or the lid can be removed from the base by moving the ends of the first and second lever towards to each other. The invention is further directed to a method for providing dental substances, a kit with an assembly, as well as the use of an assembly and a method for storing and/or delivering dental substances.
