Dropper Bottle Tip Insert for Precise Viscous Liquid Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dropper bottles are inadequate for dispensing high-viscosity liquids, as the existing piercing cap arrangement cannot produce a precise size and shape required for successful dispensing.
Innovation Solution
A tip insert for dropper bottles featuring a piercing point and a dispensing tip, along with an overcap that aligns and pierces the bottle top, allowing for precise dispensing of high-viscosity liquids by creating a controlled orifice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spike piercing arrangement is used to open the bottle, then the bottle can be easily opened and sealed, but the opening size and shape cannot be precisely controlled for high-viscosity liquids
Solution Approach 1:
The opening mechanism is divided into two separate components: a piercing spike for initial penetration and a separate precut tip for precise liquid dispensing. This segmentation allows each component to be optimized for its specific function - the spike for easy opening and the precut tip for precise control of high-viscosity liquid flow.
Solution Approach 2:
The precut tip is pre-formed with the exact opening size and shape needed for precise dispensing before the piercing operation. This preliminary preparation ensures that once the bottle is opened, the precise opening is already in place, eliminating the need to rely on the imprecise spike opening for high-viscosity liquid control.
2Manufacturing precision
If a precise tip opening is created before sealing, then precise dispensing of high-viscosity liquids is enabled, but the bottle cannot be sealed to preserve the liquid
Solution Approach 1:
The precut tip with the precise opening is manufactured and positioned in place before the bottle sealing operation. This allows the bottle to be completely sealed with the precise tip already in position, preserving the liquid until use. The sealing integrity is maintained because the precise opening is created in advance, not during or after sealing.
Solution Approach 2:
The tip assembly is separated into a precut precision portion and a piercing portion, allowing the precision element to be installed before sealing while the piercing element handles the opening operation. This segmentation resolves the conflict between needing a precise opening and maintaining sealing reliability.
3Ease of operation
If the bottle top is pierced by a spike, then the bottle can be opened, but the resulting opening is inconsistent in size and shape for precise dispensing
Solution Approach 1:
The opening system is segmented into a piercing spike that creates an initial opening and a precut tip that provides the final precise, consistent opening. The spike handles the variable task of penetrating the bottle seal, while the precut tip ensures consistent opening dimensions for precise dispensing of high-viscosity liquids.
Solution Approach 2:
The precut tip acts as an intermediary between the imprecise spike opening and the requirement for precise liquid dispensing. It receives the initial penetration from the spike and transforms it into a consistent, precisely-sized opening that ensures reliable dispensing of high-viscosity liquids.

Function Achieved in This Case
Enables the precise dispensing of high-viscosity liquids from sealed bottles by ensuring a consistent and controlled opening, overcoming the limitations of conventional dropper bottles with soft plastic resin.
Implementation Method 1
a piercing point at a lower end of the insert body for piercing a top surface of the bottle and for retaining the tip insert on the top surface of the bottle after piercing
Implementation Method 2
a dispensing tip at the insert body upper surface communicating with the passage for forming drops of the liquid from the bottle

AI summary
A tip arrangement for a bottle used for dispensing viscous liquid, such as drops of medicine, is provided. Embodiments include a tip insert having an insert body and a piercing point at a lower end of the insert body, for piercing a top surface of the bottle and for retaining the tip insert on the top surface of the bottle after piercing. A passage extends from a distal end of the piercing point, through the insert body, to an opposing upper surface of the insert body. A dispensing tip at the insert body upper surface communicates with the passage for precisely forming drops of the liquid from the bottle.
