Plastic Closure Integrity Element Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plastic closures with hinge connections face challenges in standard assembly machine compatibility, recognizing the first opening, and securing integrity guarantee elements to prevent loss during use and disposal.
Innovation Solution
A plastic closure design featuring a lower part with a drinking spout and a cover connected by a hinge, where the cover has a locking hook on its outer side and aprons with hook locking windows, and an integrity guarantee element molded on the cover's jacket wall, which separates by swiveling and remains secured within the closure, allowing easy recognition of the first opening and preventing loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the integrity guarantee element is made as a separate guarantee band that engages over protruding beads, then the guarantee band can be constituted in a different color for visual recognition, but the separated parts become relatively large and are torn off and thrown away carelessly
Solution Approach 1:
The integrity guarantee element is segmented into two parts: a stationary guarantee band on the lower part and a movable platelet on the cover. This segmentation allows the guarantee band to remain on the container while the platelet moves during opening, preventing loss and enabling visual recognition through color differentiation.
Solution Approach 2:
The integrity guarantee element transitions from a two-dimensional band to a three-dimensional structure with a platelet that can move in space. The platelet is positioned to swing during opening, adding a dimensional aspect that prevents careless disposal while maintaining visual recognition capabilities.
2Ease of operation
If the integrity guarantee element is designed as a shield-shaped tilting plate that hooks on the lower part, then the closure can be opened by pressing and destroying a predetermined breaking point bridge, but the consumer can scarcely recognize the integrity of the product
Solution Approach 1:
The guarantee band is constituted in a different color from the plastic closure itself, enabling ready visual recognition. The platelet can also be colored differently, creating a visually distinct integrity indication that consumers can easily recognize without confusion.
Solution Approach 2:
The integrity guarantee element is divided into a stationary colored guarantee band and a movable platelet. This segmentation ensures that the colored band remains visible on the container to indicate integrity, while the platelet's movement during opening provides operational functionality.
3Reliability
If the integrity guarantee element is molded on the cover surface with locking hooks engaging in recesses in the lower part, then the guarantee band provides connection between closure and container, but the separated parts are relatively large and torn off carelessly
Solution Approach 1:
The integrity guarantee element is segmented into a stationary guarantee band and a movable platelet. The guarantee band remains anchored to the lower part providing reliable connection, while the platelet on the cover swings during opening and can be easily removed without loss, as it is guided to remain on the closure.
Solution Approach 2:
The platelet acts as an intermediary between the guarantee band and the cover. It transfers the connection function during closed state and enables easy separation during opening while preventing loss through its guided movement path that keeps it associated with the closure.
4Productivity
If conventional assembly machines are used with hinge connections, then standard assembly processes can be applied, but the machines have difficulty recognizing the first opening and handling the integrity guarantee element
Solution Approach 1:
The platelet is designed to swing dynamically during the first opening motion. This dynamic movement creates a detectable change that assembly machines can recognize to identify first opening events, enabling automated detection without compromising assembly speed.
Solution Approach 2:
The platelet is pre-positioned in a specific orientation during closure assembly. This preliminary positioning allows assembly machines to detect the initial state and recognize when the first opening occurs, facilitating automated process control while maintaining productivity.

AI summary
In order to prevent or minimize littering, the invention proposes a plastic closure (1) having a tamper-proof element. The plastic closure has a tamper-proof element that is as small as possible, and the plastic closure is largely secured against loss. The tamper-proof element consists of a plate (50), which is formed as part of the jacket wall (30) of the cover (3) by means of designed breaking point bridges (51, 52) and lies behind a first apron (25) in the closed state before the first opening and engages in a window (26) of the first apron by means of a locking hook. After the first opening, the plate (50) is separated from the cover and is held captive between the first apron (25) and a second, inner apron (27).
