Rotary Chute Dispenser Cap for Precise Granular Product Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dispensers for granular and powdered products, such as salt, fail to provide precise dosing, as they allow only regulated but not accurate dispensing of the product.
Innovation Solution
A cylindrical body chute with a cradle-mounted design, featuring first and second angularly spaced openings, allows for relative rotation between a loading and discharge position, enabling precise dosing by pivoting on a virtual longitudinal axis with a manually operated flap, ensuring controlled product flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a disc with perforations and manual rotation is used, then the outflow of salt can be regulated, but precise dosing cannot be achieved
Solution Approach 1:
The chute is made rotatable around a vertical axis, transforming a static dispensing system into a dynamic one. By rotating the chute between different angular positions, the system can selectively align different openings with the container opening, enabling precise control over the amount of product dispensed while maintaining ease of operation through simple manual rotation.
2Adaptability or versatility
If holes of varied section are used in the cap, then more or less regulated dispensing is possible, but correct and precise dosage in required quantities is not permitted
Solution Approach 1:
The chute is divided into multiple angularly spaced openings instead of using a single opening or varied hole sections. Each opening can be independently aligned with the container opening through rotation, allowing precise dosing by selecting which opening is active. This segmentation enables both adaptability in dispensing regulation and precision in dosage control.

AI summary
A dispenser (a) applicable to cap of a container (b) for granular and/or powdered products. The present dispenser (a) comprises a cylindrical body chute (10) with the required capacity, which is mounted with the possibility of relative rotation, on a virtual longitudinal (11) axis, in a cradle (2) formed on the wall of a lateral recess of the cap (b) of the container (c), being said chute provided with a projecting peripheral flap (14) acting as a manually operated turning means. The wall of the cradle (2) has an opening (3) facing the interior of the container (c) and the chute (10) has first and second openings (12-13) angularly separated. Chute (10) can run between a product loading position, with the first opening (12) facing the opening (3) of the cradle and the second opening (13) closed by the wall of the cradle, and a product discharge position, with the first opening (12) closed by the wall of the cradle (2) and the second opening (13) facing the outside of the cap.
