Disc Closure Assembly with Sliding Tracks for Leak-Tight Viscous Product Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container closure systems fail to provide a leak-tight and easy-to-operate solution that allows for simple horizontal opening and closing, while also enabling the container to be used as a tottle for viscous products, which are difficult to dispense when nearly empty.
Innovation Solution
A closure assembly featuring a disc-shaped closure with parallel tracks and railings for sliding engagement, combined with a resilient disc for leak-tight sealing, and a v-shaped edge for stable inversion, allowing easy horizontal operation and leak-proof closure, enabling the container to function both as a bottle and a tottle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded screw closure is used, then leak-tight closure is achieved, but ease of operation deteriorates requiring undue pressure
Solution Approach 1:
The closure assembly is segmented into distinct functional components: a disc-shaped closure element for sealing, a slider mechanism for operation, and a container head with integrated features. This segmentation allows each component to perform its specific function efficiently - the disc provides sealing, the slider provides easy operation, and they work together to resolve the contradiction between leak-tightness and ease of use.
Solution Approach 2:
The patent merges the closure function and the pouring spout function into a single integrated disc-shaped closure element. The closure element simultaneously provides leak-tight sealing when closed and acts as a pouring spout when opened, eliminating the need for separate components and resolving the contradiction by combining sealing reliability with operational simplicity in one unified structure.
2Ease of operation
If a flip-top closure is used, then ease of operation is improved, but leak-tight closure deteriorates
Solution Approach 1:
The disc-shaped closure element has different functional zones with different properties: one surface provides a smooth flipping action for ease of operation, while the opposing surface integrates a pouring spout structure that ensures leak-tight closure. This local differentiation of qualities within the single closure element resolves the contradiction between operational simplicity and sealing reliability.
3Ease of manufacture
If a standard bottle configuration is used, then ease of manufacture is improved, but adaptability deteriorates for viscous products
Solution Approach 1:
The container system is designed with multi-functionality: the container body can function as a standard bottle when placed upright, and the integrated closure element with pouring spout enables it to function as a tottle when inverted. This universal design allows the same manufactured product to adapt to different usage scenarios, particularly for viscous products, without requiring separate manufacturing processes.
4Device complexity
If the container is designed as a bottle only, then device complexity is reduced, but versatility deteriorates
Solution Approach 1:
The closure assembly incorporates dynamic elements including a movable disc-shaped closure that can transition between closed and open positions, and an integrated pouring spout that enables functional transformation. These dynamic features allow the container to switch between bottle and tottle modes without adding significant structural complexity, resolving the contradiction between simplicity and versatility.
