Flexible Sheet Beverage Pourer for Non-Drip Bottle Pouring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage pourers often result in dripping and spillage when pouring from glass bottles, especially at the end of the pour, leading to waste and soiling.
Innovation Solution
A one-piece, elastically flexible sheet pourer with embossed surfaces that forms a non-drip pour channel by conforming to the bottle's inner perimeter, preventing leakage by engaging the bottle's inner surface and guiding the flow through a channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional pourer is used, then the beverage can be poured, but dripping and spillage occur at the end of the pour
Solution Approach 1:
The invention uses a flexible sheet member that can be manually flexed and inserted into the bottle opening. The sheet conforms to the bottle's inner perimeter and forms a pour channel, preventing dripping without requiring the user to twist the bottle. The flexibility of the sheet allows it to adapt to the bottle opening while maintaining its drip-prevention function.
2Adaptability or versatility
If the sheet is made elastically flexible, then it can be manually inserted and conform to the bottle, but it may deform under beverage flow
Solution Approach 1:
The sheet member has different structural characteristics in different regions. The embossed upper surface creates raised regions and recessed regions that provide structural reinforcement where needed, while the overall sheet remains flexible for insertion. This local variation in structure allows the sheet to conform to the bottle opening while resisting deformation under beverage flow pressure.
Solution Approach 2:
The sheet member features an embossed upper surface with curved raised regions and recessed regions. These curved structures provide structural integrity and resistance to deformation while maintaining the flexibility needed for manual insertion and conformation to the bottle opening.
3Volume of moving object
If the sheet is made compact and flat, then it is easy to store and handle, but it lacks structural support for forming a stable pour channel
Solution Approach 1:
The upper surface of the sheet is segmented into raised regions and recessed regions through embossing. This segmentation creates a stable pour channel structure that maintains its shape during pouring, while the overall sheet remains compact and flat for easy storage and handling. The segmented structure provides the necessary structural support without increasing the overall volume.
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
Prevents dripping and spillage without the need for twisting the bottle, promoting aeration and maintaining a compact, flat design for ease of use.
Implementation Method 1
The sheet is adapted and configured to be manually flexed transversely to impart concavity to the upper surface, the flexed sheet being manually insertable through a round pour opening of a beverage bottle
Implementation Method 2
The lower surface of the sheet thus partially inserted and released is adapted and configured so to engage an inner surface of the beverage bottle as to restrict the beverage from flowing between the sheet lower surface and the beverage bottle inner surface

AI summary
A non-drip beverage pourer in the form of a one-piece, round, elastically flexible sheet with an embossed pouring surface. When flexed (folded or rolled) to form the pouring surface into a “U” or tube shape, partially inserted through a pour opening and into a neck of a bottle, and released, the sheet passively conforms to the shape of the bottle opening to form a pour channel. Raised and recessed features on the pouring surface cause the beverage to be aerated when poured from the bottle through the pour channel.
