Beverage Container Closure With Vertical Open-Close Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage containers with complex structures and multiple parts are difficult to produce and maintain, and users face challenges in accessing and cleaning them effectively.
Innovation Solution
A closure system for beverage containers featuring a simple design with few parts, including an insert element with a continuous closure opening and a closure body with discharge openings, allowing for easy operation and secure handling, where the closure body moves vertically to seal or open passages for liquid, and includes flexible hooks for secure attachment and easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beverage containers use multiple individual parts and complex structure to ensure thermal insulation and prevent spillage, then reliability is improved, but device complexity increases and ease of manufacture deteriorates
Solution Approach 1:
The patent combines the closure body and insert element into a integrated closure system where the closure body fits within the insert element. The closure body includes integrated components (sealing element, discharge openings, engaging structures) that work together to provide thermal insulation, spillage prevention, and easy operation through a unified structure rather than separate parts.
Solution Approach 2:
The closure body serves multiple functions: it provides thermal insulation through its structure, prevents spillage via the sealing element and controlled discharge openings, enables easy operation through engaging structures, and allows cleaning access. This multi-functionality reduces the need for additional separate components.
2Reliability
If beverage containers use multiple individual parts to achieve sealing and drinking functions, then reliability is improved, but ease of operation deteriorates due to difficulty in accessing parts for cleaning
Solution Approach 1:
The closure is divided into two main segments: the closure body and the insert element. The closure body can be removed from the insert element by releasing the engaging structures, providing easy access for cleaning while maintaining reliable sealing when assembled. This segmentation allows cleaning of internal parts without disassembling the entire container.
3Ease of operation
If the closure body is completely removed from the container for drinking, then ease of operation is improved, but reliability deteriorates due to potential accidental spillage
Solution Approach 1:
The closure body can be dynamically positioned in different states: fully inserted for sealed storage, partially inserted to open discharge openings for controlled drinking, or completely removed for cleaning. The engaging structures allow easy transition between these states while the sealing element prevents spillage in the closed position.
Solution Approach 2:
The insert element acts as an intermediary between the closure body and the beverage container. It provides the sealing connection to the container while allowing the closure body to be attached or detached. The insert element's continuous closure opening and engaging structures mediate between the need for secure sealing and easy operation.
4Reliability
If the closure has many individual parts to ensure proper sealing and function, then reliability is improved, but ease of manufacture deteriorates due to increased production complexity and cost
Solution Approach 1:
The closure body and insert element are designed as integrated components that can be manufactured separately and assembled through simple engaging structures. The sealing element is integrated into the closure body, reducing the need for additional separate sealing components. This merging approach simplifies manufacturing while maintaining reliable sealing function.

AI summary
A closure for a beverage container is disclosed. Said closure comprises an inserted element (2) and a closing member (3) which can be inserted into a mouth of the inserted element (2). A first engaging structure (22) mounted on the internal face of the inserted element (2) can be connected to a second engaging structure (36) arranged on the external face of the closing member (3). The inserted element (2) further has a funnel section (25) above the first engaging structure (22). The closing member (3) has a closed top surface (32), a handle element (31), and an apron (35) with outlets (33). The engaging structures (22, 36) are designed such that the closing member (3) can be moved relative to the inserted element in a vertical direction between a first position in which the closing member (3) seals the mouth and a second position in which the outlets (33) open passages for a liquid.
