Break-Off Lid Container for Stable Upright Dental Adhesive Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental adhesive containers either remain integrally connected after opening, leading to instability and inconvenience in use, or separate into body and lid, causing leakage and bulkiness during shipping and storage.
Innovation Solution
A container design featuring a container body with engaging and auxiliary protrusions that allow the lid member to maintain the body in an erected position after separation, using a brittle junction that can be broken for easy disassembly and reassembly, with an elastic closing member to prevent content leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the container body and lid member remain integrally connected after opening, then the container can be discarded without separation, but the container becomes long in longitudinal direction and loses stability when erected
Solution Approach 1:
The container is divided into two separable parts: a container body and a lid member connected by a brittle portion. This segmentation allows the container to be stable when erected (lid provides support) while enabling easy separation for disposal by breaking the brittle connection point.
2Stability of the object's composition
If the container body and lid member are separated by breaking the junction, then the container can be stabilized when erected, but the content may leak out during separation
Solution Approach 1:
The brittle portion is pre-designed with a specific breaking point that separates the lid from the container body. The breaking point is positioned and structured so that when force is applied to separate the lid, the brittle junction breaks in a controlled manner that prevents adhesive content from leaking out.
3Stability of the object's composition
If a large pedestal is formed to enable stable standing, then the container can be erected stably, but the container becomes bulky and difficult to pack
Solution Approach 1:
Instead of increasing the horizontal footprint (pedestal size) for stability, the invention uses the vertical dimension by having the lid member extend upward. The lid acts as a vertical support element that provides stability when the container is erected, without increasing the horizontal space required for packaging.
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 container maintains stability and prevents content leakage while allowing for easy handling and storage, reducing bulkiness during shipping and enabling efficient use of the lid member before disposal.
Implementation Method 1
a brittle portion 68 is formed between the container body 62 and the lid member 63, the brittle portion 68 being bonded by melt-adhesion or the like method

AI summary
A container which is not bulky at the time of shipping and can be stably stood on a suitable place. The container includes a lid member for closing a take-out opening (brittle portion) of the container body 2. On the lower outer side of the container body, there are formed slits for fitting the lid member to the container body after the container body and the lid member are separated apart, and auxiliary leg portions that protrude outward of the container body. The lid member is forming holding leg portions that protrude outward therefrom. Wing portions of the holding leg portions are inserted in the slits to fit the lid member to the container body, and the erected attitude of the container body is supported by the holding leg portions.
