Segmented Thread Ribs for Rapid Container Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container designs with screw-type closures are inconvenient to use due to the need for precise alignment and rotation, often requiring complex threading and overlapping ribs, which can be cumbersome and aesthetically unappealing.
Innovation Solution
A container design featuring thread ribs on the lid and base with a circumferential angle of 90 degrees or less, allowing for rapid rotary attachment and closure with only two thread ribs spaced apart, enabling easy alignment and minimal vertical movement, and incorporating stop sections for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw-type closures with complex threading are used, then secure closure is achieved, but ease of operation deteriorates due to requiring precise alignment and rotation
Solution Approach 1:
The threading is segmented into discrete thread ribs with circumferential gaps rather than continuous threading. This segmentation allows the lid and base to be aligned and closed with minimal rotation, eliminating the need for precise alignment while maintaining secure closure through the interlocking thread ribs.
Solution Approach 2:
Instead of requiring full 360-degree rotation for closure, the invention uses partial action with thread ribs extending over circumferential angles of 90 degrees or less. This partial threading approach achieves secure closure with minimal rotational movement, significantly improving ease of operation.
2Reliability
If multiple overlapping thread ribs are used, then closure security is improved, but device complexity increases
Solution Approach 1:
The closure mechanism is segmented into a limited number of discrete thread ribs (at least two) positioned at specific circumferential locations rather than using multiple overlapping continuous threads. This reduces structural complexity while maintaining closure security through the spaced arrangement of thread ribs.
Solution Approach 2:
The thread ribs are positioned asymmetrically with circumferential gaps between them rather than being uniformly distributed. This asymmetric placement simplifies the overall structure by eliminating the need for symmetric overlapping patterns while still achieving secure closure through the strategic positioning of thread ribs.
3Reliability
If thread ribs extend over large circumferential angles, then closure security is improved, but ease of operation worsens due to requiring more rotation
Solution Approach 1:
The thread ribs are designed to extend over circumferential angles of 90 degrees or less, utilizing partial action rather than full-circle threading. This allows the lid and base to be quickly aligned and closed with minimal rotation, reducing closure time while maintaining adequate closure security through the interlocking action of the thread ribs.
Solution Approach 2:
The circumferential angle parameter of the thread ribs is optimized to 90 degrees or less, changing the traditional parameter of larger threading angles. This parameter change reduces the rotational distance required for closure, thereby reducing closure time while the vertical spacing and positioning of thread ribs maintain closure security.

AI summary
The invention relates to a container (1), comprising a container cover (2) and a container bottom part (3), wherein the container cover (2) and the container bottom part (3) can be screwed to each other by means of thread forms in the form of thread ribs (5, 6, 7, 8) on the container cover (2) and on the container bottom part (3) by rotating the cover and the bottom part in relation to each other about a screwing rotational axis (A). The thread ribs (5, 6, 7, 8) formed on the container cover (2) and on the container bottom part (3) are formed over a circumferential angle of 90 degrees or less and leave a distance in the circumferential direction on the cover and the bottom part, wherein on the cover and the bottom part at least two thread ribs (5, 6, 7, 8) are formed in an opposed position, wherein furthermore in a superimposed position in the direction of the screwing rotational axis (A) of a thread rib (5, 6, 7, 8) of the bottom part or of the cover in the course of a threaded connection, a complete overflow in the circumferential direction is possible only in one of the two opposed positions.
