Divisible Bottle With Integrated Elastic Tube for Sterile Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breakable bottles for pharmaceutical or cosmetic liquids face issues with the sharp edge and size of the opening after breaking, making it difficult to apply the liquid safely and hygienically, especially on sensitive areas, and require additional assembly of separate dispensing devices which can compromise sterility and convenience.
Innovation Solution
A divisible bottle design with a one-piece body, a leaktight base, and an elastically deformable hollow tube integrated within the cap, allowing safe and precise dispensing without external parts, ensuring hygiene and ease of use by bending during rupture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate dispensing device is provided and assembled into the bottle after breaking, then the liquid can be dispensed more precisely and safely, but the sterility of the liquid cannot be guaranteed and the implementation becomes inconvenient
Solution Approach 1:
The dispensing device is integrated into the bottle structure itself, with the hollow tube formed as part of the bottle body. This merging eliminates the need for separate assembly operations, maintaining sterility while providing controlled dispensing through the integrated tube that extends from the rupture zone to the cap.
Solution Approach 2:
The hollow tube is pre-formed as part of the bottle structure before use, positioned to extend from the rupture zone to the cap. This preliminary preparation allows immediate sterile dispensing upon breaking, without requiring post-breakage assembly of separate components.
2Ease of operation
If a separate dispensing device is assembled into the bottle after breaking, then the liquid can be dispensed more precisely and safely, but the implementation becomes inconvenient and complex
Solution Approach 1:
The dispensing function is merged into the bottle structure itself. The hollow tube is formed as an integral part of the bottle body, eliminating separate dispensing components and assembly steps, thereby reducing device complexity while maintaining precise dispensing capability.
Solution Approach 2:
The bottle structure serves multiple functions: containment, controlled rupture, and precise dispensing. The hollow tube integrated into the bottle body provides both structural support and liquid conduction, eliminating the need for separate dispensing devices.
3Ease of operation
If the opening created after breaking is used directly, then the bottle is simple to use, but the opening has sharp edges and asperities making it unsafe for sensitive areas
Solution Approach 1:
The hollow tube acts as an intermediary between the rupture zone and the external environment. It provides a smooth, controlled opening for liquid dispensing, eliminating the harmful sharp edges and asperities of the direct rupture opening while maintaining simple operation.
Solution Approach 2:
The opening characteristics are differentiated: the rupture zone provides controlled separation, while the hollow tube provides a smooth dispensing opening. This local quality change ensures safety at the liquid exit point without complicating the overall simplicity of use.
4Ease of operation
If the opening has relatively large dimensions, then the bottle is simple to break and use, but precise application on a very localized area becomes problematic
Solution Approach 1:
The hollow tube serves as an intermediary that controls liquid flow precision. Its narrow dimensions enable precise localized application, while the simple breaking action at the rupture zone maintains ease of operation. The tube acts as a flow control element between the large rupture opening and the precise application point.
Solution Approach 2:
Different parts of the system have different dimensional characteristics: the rupture zone has large dimensions for easy breaking, while the hollow tube has narrow dimensions for precise application. This local quality differentiation resolves the contradiction between ease of operation and precision.

Implementation Method 1
said tube being elastically deformable, so that it can be bent without breaking during the rupture of the body
Implementation Method 2
a base arranged to be fixed with sealing in the main part of the body
Implementation Method 3
a part forming the bottom, separate from the body and secured to the upstream end of said body in a leaktight manner

AI summary
The bottle (1) has a bottom (14) integrated to an upper end of a body (2) in a sealed manner. A drip type liquid distribution device (18) comprises a base (20) tightly fixed with a main part (4) of the body and a hollow tube (23) connected to the base. The tube extends at inside of a cap (11) before rupture of the body and allows flow of liquid in the bottle to outside when the body is broken at level of a rupture zone (13). The tube is elastically deformed such that the tube is bent without breaking during rupture of the body.
