Plastic Container Opening Means with Articulated Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic containers with integrated dispensing devices are complex, expensive, and prone to errors in substrate discharge, often resulting in incomplete and uncontrolled dispensing, with components being difficult to assemble and clean.
Innovation Solution
A plastic container design featuring a container body and cover with an articulated connection section that allows for easy opening and controlled substrate release, using a loop-shaped or U-shaped connecting element to facilitate displacement and restore the container to a closed position, and optionally incorporating a piercer or flaps for precise substrate dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate components (container body, punch, sealing film) are used to create an integrated dispensing device, then the container can achieve substrate dispensing function, but the production cost increases and manufacturing complexity increases
Solution Approach 1:
The container body and container cover are merged into a single integrally molded unit, eliminating the need for separate components and assembly processes. The opening means is integrated directly into the container body structure, further reducing part count while maintaining the substrate dispensing function.
Solution Approach 2:
The container body serves multiple functions: it contains the substrate, provides the opening means for dispensing, and includes the articulated connection section for controlled opening. This multi-functionality eliminates the need for separate dispensing devices while achieving the same effect.
2Reliability
If a sealing film is used to close the container chamber, then the container can be sealed, but the severed film remains in the mixing container and is difficult to remove
Solution Approach 1:
The sealing function is extracted from a separate sealing film and integrated into the container cover structure itself. The container cover with integrated opening means opens cleanly without leaving residual film fragments in the mixing container, solving the removal difficulty.
3Ease of operation
If the substrate is discharged through a simple opening mechanism, then the container can be opened easily, but the substrate discharge is uncontrolled and may get stuck on the mixing container neck
Solution Approach 1:
The opening means is designed to move dynamically from a closed to an open position through the articulated connection section. This controlled movement allows precise substrate discharge along the container axis, preventing uncontrolled scattering and sticking on the mixing container neck.
4Ease of operation
If the container cover is pressed out of snap-in connection with large force, then the container can be opened, but the hinge bridge may break and the sealing lid may fall into the mixing container
Solution Approach 1:
The container cover opening is transformed from a static snap-in connection requiring large force to a dynamic articulated movement. The articulated connection section allows gradual, controlled opening with minimal force, preventing hinge bridge breakage and seal lid fallout.
Solution Approach 2:
The opening mechanism changes from requiring high force (static) to requiring minimal force (dynamic). The articulated connection section modifies the force parameter needed for opening, making it gentle and controlled rather than abrupt and high-force.

Function Achieved in This Case
The design enables cost-efficient production, controlled substrate release, and easy removal from mixing containers, reducing the risk of components sticking and ensuring complete dispensing into the mixing container.
Implementation Method 1
The upper border is connected to the container wall via an articulated connection section, the articulated connection section allowing the upper border to be displaced relative to the container wall

AI summary
The invention relates to a plastic container, comprising a container body (1), a container cover (2, 2', 2''), and an opening means (9) for opening the container cover (2, 2', 2''). The container body (1) comprises a container wall (3) and a container bottom (4) arranged in a lower region. A container opening (5) is formed at an upper end of the container body (1) lying opposite the container bottom (4). The container body (1) comprises a peripherally extending upper border (6) in the upper region. The container cover (2, 2', 2'') is fastened to the upper border (6) of the container body (1) in order to cover the container opening. According to the invention, the upper border (6) is connected to the container wall (3) at a distance radially outward from an upper edge (7) of the container wall (3) and by means of a flexible connecting portion (8), the flexible connecting portion (8) permitting sliding of the upper border (6) relative to the container wall (3) and to the opening means (9) such that the plastic container can be brought from a closed position into an open position.
