Child-Proof Capsule Reducer Anchoring via Radial Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child-proof capsules with syringe dosers often have small parts that can detach during use, posing a risk of accidental ingestion by children, and are difficult to package automatically without deformation.
Innovation Solution
A child-proof capsule design featuring a reducer with radial projections and annular cavities that securely anchor to the container, preventing accidental detachment and allowing easy insertion with automatic packaging machines, while maintaining stability and preventing deformation during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a syringe doser is applied on a child-proof capsule with a perforated cap reducer, then a predetermined dose of product can be dispensed, but the reducer can detach from the container and fall or remain connected to the syringe, creating a risk of accidental ingestion by children
Solution Approach 1:
The reducer is integrated with the capsule structure by providing radial projections on the reducer that insert into recesses in the capsule, and annular cavities in the capsule that receive the reducer. This merging ensures the reducer remains securely attached to the container throughout the dosing process, eliminating the risk of detachment and accidental ingestion while maintaining ease of syringe application.
2Ease of manufacture
If a traditional reducer design is used in child-proof capsules, then the capsule can be assembled, but the reducer hole deforms during packaging, affecting the functionality and safety
Solution Approach 1:
The capsule structure incorporates annular cavities at specific locations to receive and support the reducer, providing localized structural reinforcement. This local quality enhancement prevents deformation of the reducer hole during packaging and use, while maintaining ease of assembly with automatic packaging machines.
3Reliability
If the capsule is designed with child-proof mechanisms, then safety against children is improved, but the capsule becomes more complex and difficult to package automatically
Solution Approach 1:
The reducer is nested within the capsule structure, with radial projections fitting into recesses and annular cavities receiving the reducer. This nesting arrangement provides child-proof safety mechanisms while maintaining a compact, simple structure that is easy to assemble with automatic packaging machines, avoiding excessive complexity.

AI summary
The capsule comprises: an internal capsule (4), which inserts removably in a mouth (2) of a container (1) to be closed, having an external cover (5), creating a security opening of the container (1); a reducer (7) which is applied on the mouth (2) of the container (1) and which is provided with an upper wall (70), in which a hole (71) is afforded, in which a syringe doser (8) can be introduced. The reducer (7) comprises: at least a radial projection (72) in the upper wall (70) thereof, which inserts in an annular recess (40) internally afforded in the upper part of the internal capsule (4); a first annular cavity (73), delimited by an external wall (74) and an internal wall (75) which develop axially below the upper wall (70) of the reducer (7), in which upper wall (70) an overhang (20) developing axially from the upper end of the mouth (2) of the container (1) is anchored.
