Removable Bottle Bottom Assembly for Tight Sealing and Hygienic Drinking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottles with removable bottoms for direct drinking pose issues with suboptimal tightness, difficult unscrewing, and hygiene concerns when converted into a glass.
Innovation Solution
A bottle design featuring a removable bottom with pressure-fitted shaped elements and a tightening collar for improved tightness, along with a metal counter-lid and polyethylene disc for enhanced hygiene and anti-tampering, allowing comfortable removal and use as a glass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bottom is screwed onto the shaped body of the bottle, then the bottle can be sealed, but the tightness is not optimal and unscrewing is difficult
Solution Approach 1:
The bottom assembly is segmented into multiple components: a bottom piece, a lid, and a tightening collar that can be independently manipulated. This segmentation allows the lid to remain sealed during opening operations while the bottom piece is removed, resolving the contradiction between maintaining tightness and enabling easy opening.
Solution Approach 2:
The functional elements for sealing (lid and tightening collar) are extracted from the bottom assembly and separated from the bottom piece. This allows the sealing mechanism to remain intact and effective while the bottom piece can be easily removed by simply unscrewing it from the bottle body.
2Adaptability or versatility
If the bottle body is converted into a glass for direct drinking, then no external glass is needed, but hygiene is compromised due to contact with lips
Solution Approach 1:
The bottom assembly is segmented into a removable bottom piece and a separate lid with tightening collar. This allows the lid to remain attached to the bottle body during drinking, creating a hygienic barrier between the beverage and the user's lips while still enabling direct drinking from the bottle opening.
Solution Approach 2:
The lid acts as an intermediary element between the beverage and the user's lips. It provides a hygienic surface for drinking while remaining attached to the bottle body, thus maintaining the bottle-to-glass conversion functionality without compromising hygiene.
3Ease of manufacture
If the bottom is screwed onto the shaped body, then the bottle can be assembled, but the tightness guarantee is not optimal
Solution Approach 1:
The lid and tightening collar are pre-assembled onto the bottom piece during manufacturing. This preliminary assembly ensures proper alignment and pre-compression of sealing surfaces, guaranteeing optimal tightness when the bottom assembly is screwed onto the bottle body, while maintaining ease of assembly.
Solution Approach 2:
The tightening collar is designed to modify the compression parameter on the sealing surfaces. By adjusting the tightening collar during assembly, optimal contact pressure is achieved between sealing surfaces, ensuring reliable tightness while maintaining simple assembly procedures.
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 design ensures better tightness, easier removal, and improved hygiene by preventing foreign body introduction, while the tightening collar acts as an anti-tampering indicator.
Implementation Method 1
Said bottom is provided with a plurality of elastic projections spaced from one another and distributed along a circumference
Implementation Method 2
a removable bottom comprising one or more shaped elements pressure-fitted to the shaped body of the same bottle
