Rotating Slider Lid Structure for Hygienic Fluid-Tight Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lids for containers holding flowable substances have hygienic deficiencies and complex designs, particularly in their mechanism for opening and closing.
Innovation Solution
A lid with a form-fit and/or force-fit connection between a convexity on the lid and a slider that rotates around a vertical axis, featuring a content indicator system and a sealing mechanism that allows for easy production and improved hygiene by preventing substance accumulation and ensuring a secure, fluid-tight seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional lid design with opening/closing mechanism is used, then the lid can control substance removal, but the design becomes complicated and creates hygienic deficiencies with substance accumulation
Solution Approach 1:
The invention extracts the opening and closing function from a complex mechanical mechanism and implements it through a simple slider component that rotates around a vertical axis. The slider selectively covers or uncovers the opening, providing the required function without the complexity of traditional latch mechanisms, thereby eliminating substance accumulation zones while maintaining operational control.
Solution Approach 2:
Instead of using a complex mechanism to actively open the lid, the invention inverts the approach by using a simple slider that passively covers the opening when in its closed position. The opening action is achieved by simply rotating the slider away, rather than requiring multiple components to actively pry or lift the lid open, thus simplifying the overall design while maintaining hygiene.
2Ease of manufacture
If a form-fit connection between convexity and slider opening is used, then production is simplified and hygiene is improved, but the connection must accommodate production tolerances
Solution Approach 1:
The invention employs a form-fit connection between the convexity and the slider opening that is designed to accommodate normal production tolerances. The geometric shapes are configured such that slight variations in manufacturing dimensions do not prevent proper assembly or function. The connection relies on the interlocking form rather than precise dimensional matching, allowing easy manufacture while maintaining functional integrity.
3Device complexity
If the slider rotates around a vertical axis, then the structure is simplified and production is easier, but the sealing mechanism must ensure fluid-tight closure
Solution Approach 1:
The invention introduces a sealing element as an intermediary component between the slider and the lid body. This sealing mediator ensures fluid-tight closure while allowing the slider to rotate around a vertical axis with a simple structure. The sealing element compensates for any minor gaps that may exist due to the rotational movement, maintaining reliability without complicating the overall structure.

AI summary
The present invention relates to a lid for a container holding a flowable substance which comprises a mounting portion to be attached to the container and an opening to remove the flowable substance from the container, whereas the opening is opened and closed by means of a slider which is connected to the lid and rotates around a vertical axis.
