Solution Overview

Problem

Existing liquid candy dispensing containers require excessive tongue movement, risking choking and inadequate taste distribution due to the design of rotating spherical bodies, which do not effectively target taste buds on the distal tongue.

Innovation Solution

A gasket part in the form of a spherical sector or dome with small holes, extending into the container neck, allowing controlled product flow upon tilting, and a cap with a gasket ring to prevent accidental leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a spherical body is used in a conventional roll-on container, then the container can be rotated on the user's tongue, but the container must move an excessive distance along the tongue causing choking and gagging

Engineering Contradiction:
Improveease of useVSAvoidchoking and gagging
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The spherical body is segmented into a spherical dome with multiple small holes distributed across its surface. This segmentation allows the liquid candy to be dispensed through multiple outlets simultaneously, reducing the distance the container needs to move along the tongue while ensuring adequate product application to the distal end.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of relying on the user to roll the entire spherical body along the tongue to bring the impregnated surface to the distal end, the invention inverts the approach by having multiple small holes distribute liquid candy directly to the distal end of the tongue where taste buds are concentrated, eliminating the need for excessive tongue movement.

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If a spherical body is used in a conventional roll-on container, then the container can be rotated on the user's tongue, but much of the product is not applied to the distal end of the tongue where taste buds are concentrated

Engineering Contradiction:
Improveease of useVSAvoidtasting quality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The spherical dome is equipped with multiple small holes strategically positioned to direct liquid candy to the distal end of the tongue where sweet taste buds are concentrated. This local quality enhancement ensures that the product is applied precisely where it is most effective for tasting, rather than relying on general distribution across the entire tongue surface.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention inverts the conventional approach by not relying on the user to manually position the impregnated surface against the distal end of the tongue. Instead, the multiple small holes in the spherical dome actively distribute liquid candy to this specific region, ensuring reliable product application to the taste-sensitive area regardless of user technique.

Inventive Principle:
Principle #13The other way round (Inversion)

3Ease of operation

If the cap is removed to allow product dispensing, then the user can consume the product, but the product may accidentally come out when the container is tilted

Engineering Contradiction:
Improveease of useVSAvoidleakage prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cap is designed with a gasket ring that comes into contact with the holes in the spherical dome during the closing maneuver. This preliminary action of the gasket ring sealing against the holes prevents the product from accidentally coming out when the container is tilted, while still allowing easy removal of the cap for product consumption.

Inventive Principle:
Principle #10Preliminary action

4Device complexity

If a spherical body is used, then the container has a simple structure, but the product flow control is poor

Engineering Contradiction:
Improvestructure simplicityVSAvoidproduct flow control
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The spherical body is segmented into a spherical dome with multiple small holes, providing controlled product flow through multiple outlets. This segmentation maintains relative structural simplicity while significantly improving flow control and distribution to the distal end of the tongue.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spherical dome functions as a porous structure with multiple small holes distributed across its surface. This porous configuration allows controlled dispensing of liquid candy through the holes, providing reliable flow control while maintaining the simplicity of the spherical form factor.

Inventive Principle:
Principle #31Porous materials

AI summary

Especially designed for the confectionery industry, the device of the invention consists of a hygienic and safe dispensing element for children's use, which allows optimal tasting of the product contained inside. For this purpose, the main body (1) of the container includes a tapered neck (2) on top to which is attached a gasket-dispenser (8) having a configuration in the form of a spherical dome, equipped with one or more holes (9) for the product to be dosed, complemented by the corresponding closing cap (5). The gasket-dispenser (8) extends downwards into a cylindrical tubular neck (10), the outer diameter of which is identical to the inner diameter of a perimeter narrowing (12) provided in the neck (2) of the main body (1) of the container.
