Spiral Guide Glass Bottle for Smooth Liquid Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional PET bottles often experience abrupt discharge of liquid contents, leading to splashing and choking hazards, and pose difficulties in handling empty bottles due to their large volume.
Innovation Solution
A bottle design featuring a single-piece glass body with inwardly-protruded spiral guides on the inner surface of the neck, guiding liquid to flow spirally and prevent abrupt discharge, and allowing for easy reduction in volume when empty by compressing the guides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If liquid is discharged from a conventional bottle, then liquid discharge occurs, but abrupt discharge causes splashing and choking hazards
Solution Approach 1:
The patent applies spiral guides with curved surfaces inside the bottle neck to redirect liquid flow. The curved geometry of the spiral guides transforms the liquid's linear flow path into a rotational spiral path, reducing discharge velocity and preventing abrupt ejection that causes splashing and choking hazards
Solution Approach 2:
The invention introduces a rotational dimension to the liquid flow by implementing spiral guides that wrap around the bottle neck axis. This transforms the liquid's movement from a simple axial discharge to a three-dimensional spiral trajectory, controlling the flow rate and eliminating harmful splashing effects
2Reliability
If PET bottles are used for liquid containment, then gas transmittance is low and contents are protected, but empty bottles have large volume and are difficult to handle
Solution Approach 1:
The patent utilizes the inherent flexibility of PET material to enable volume reduction of empty bottles. The thin film structure of the PET bottle allows it to be compressed and collapsed after use, transforming from a rigid large-volume container to a compact form for easy disposal while maintaining its protective function during use
3Duration of action of stationary object
If glass bottles are used instead of PET bottles, then durability and reusability improve, but weight and fragility concerns arise
Solution Approach 1:
The patent employs PET material that combines the advantages of both glass and plastic: it provides the durability and reusability of glass while eliminating the weight and fragility issues. The single-piece molded PET construction creates a composite structure that is both strong and lightweight, suitable for repeated use
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The spiral guides ensure stable and smooth liquid discharge, preventing splashing and choking, while enabling efficient reduction of empty bottle volume for easier disposal.
Implementation Method 1
at least one inwardly-protruded spiral guide formed on the inner surface of the neck and configured to guide at least part of liquid to spirally flow through the channel when discharging liquid from the liquid-containing space
