Bottle Container Unsealing Prevention Mechanism

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Bottle containers with unsealing prevention members face issues such as marks left on the cap after unsealing, difficulty in providing unsealing prevention for non-circular caps, concealment of engagement pieces making it hard to identify unsealing, complex assembly processes, and challenges in sealing and ensuring the unopened condition, especially for bottles that cannot be filled from the bottom.

Innovation Solution

A bottle container design featuring a cylindrical neck with a male thread, a shoulder part with a male and female thread, an unsealing prevention member, and a cap with an unsealing means, where the unsealing prevention member is positioned between the shoulder part and cap, allowing for a single assembly process, preventing reverse rotation, and ensuring the unopened condition by maintaining the shoulder part's position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separable connection piece is used as an unsealing prevention member on the cap, then the unsealing prevention function is achieved, but marks are left on the cap after unsealing which reduce the esthetically pleasing look

Engineering Contradiction:

Improveunsealing prevention functionVSAvoidaesthetic appearance of cap

Core Design Contradiction:

ReliabilityVSShape

Solution Approach 1:

The unsealing prevention member is extracted from the cap and placed as a separate component between the cap and container body. This allows the cap to be removed cleanly without leaving marks, while the separate unsealing prevention member remains visible to indicate unsealing status.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

A separate unsealing prevention member is introduced as an intermediary component between the cap and container body. This mediator performs the unsealing prevention function and provides visual indication, while allowing the cap itself to be removed cleanly without marks.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Shape

If the unsealing prevention member is concealed by the shoulder part, then the assembly appearance is improved, but it becomes difficult to identify whether the container has been unsealed

Engineering Contradiction:

Improveassembly appearanceVSAvoidunsealing status identification

Core Design Contradiction:

ShapeVSLoss of information

Solution Approach 1:

The unsealing prevention member is positioned in a specific location (between cap and container body, visible from front) where it can provide visual information about unsealing status without interfering with the overall assembly appearance. Different parts serve different functions: the shoulder part provides aesthetic coverage while the unsealing prevention member provides status indication.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If multiple separate components (pouring cover, shoulder part, cap) are installed, then functional requirements are met, but the assembly process becomes complex

Engineering Contradiction:

Improvefunctional requirementsVSAvoidassembly process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pouring cover and shoulder part are merged into a single integrated component. This reduces the number of separate assembly steps while maintaining all necessary functions (pouring opening and engagement with container body). The unsealing prevention member is positioned to be installed simultaneously with the cap, further simplifying the process.

Inventive Principle:

Principle #5Merging (Combining)

4Reliability

If the container opening is sealed separately from the cap installation, then sealing function is ensured, but the process becomes more complex and the unopened condition cannot be reliably ensured

Engineering Contradiction:

Improvesealing functionVSAvoidassembly process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The sealing function is merged with the cap installation process. The cap itself serves as the sealing element when installed on the container body, eliminating the need for separate sealing steps. The unsealing prevention member works in conjunction with the cap to ensure the unopened condition is maintained until intentional unsealing.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A bottle container in which sealing of the opening of a container body filled with a chemical liquid etc. and installation of a shoulder part, an unsealing member, and a cap can be made at the same time and that has a shoulder part fall-off prevention mechanism. A bottle container (1) has a container body (2) having a hollow cylindrical neck (21) whose upper part is open and having a step formed on a container body shoulder; a shoulder part (3) screwed on the outer peripheral surface of the neck (21) and having on its upper surface a hollow cylindrical body (32) that has a spout at its head; a cap (4) screwed on the outer peripheral surface of the hollow cylindrical body (32) and having a spout sealing means; and an unsealing prevention member (5) installed between the shoulder par (3) and the cap (4). A projection-like reversing prevention member (38) is formed on the lower surface of the shoulder part (3), and the reversing prevention member (38) and the step of the container shoulder are in contact with each other in the direction in which reversing is impossible, forming a reversing prevention means.
