Filling Device Segmented Receiving Element for Active Substance Applicator Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing filling and closing devices for active substance applicators face challenges in achieving precise positioning, reliable sealing, and automated removal due to the geometric arrangement of the application tube, which obstructs access to the sealing rim and makes it difficult to apply counter pressure for a hermetically closed seal.
Innovation Solution
A filling and closing device with a receiving element that includes a circumferentially extending pressure surface and a receiving channel, featuring a two-part configuration with a base element and a movable cover element, allows for exact positional fixation and counter pressure application despite the application tube's obstruction, ensuring a seal-tight sealing action and automated removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the application tube extends across the sealing rim to enable precise positioning and automated removal, then the applicator can be precisely positioned and automatically removed, but the application tube covers the support surface section and obstructs access to the sealing rim for applying counter pressure
Solution Approach 1:
The receiving element is divided into a base element and a cover element that can move relative to each other. The cover element can be opened to provide access to the sealing rim area for applying counter pressure, while the base element maintains positioning of the applicator. This segmentation allows both precise positioning and access to the sealing rim.
Solution Approach 2:
The cover element is designed to be movable relative to the base element, transitioning between a closed position that allows automated removal and an open position that provides access to the sealing rim. This dynamic configuration resolves the contradiction between maintaining positioning precision and enabling access for sealing operations.
2Extent of automation
If the application tube extends across the sealing rim to enable automated removal, then the applicator can be automatically removed, but it becomes difficult to apply counter pressure across the entire sealing surface for hermetic sealing
Solution Approach 1:
The receiving element is segmented into base and cover elements. The base element provides automated removal functionality through its interaction with the application tube, while the cover element can be opened to allow application of counter pressure for hermetic sealing. This segmentation enables both automated removal and reliable sealing.
Solution Approach 2:
The cover element is opened before the sealing operation to allow counter pressure application, and then closed afterward to enable automated removal. This preliminary action sequence ensures that sealing reliability is established before automated removal is executed.
3Ease of manufacture
If the application tube is positioned to open into the receiving space, then the active substance can be administered, but the tube obstructs the sealing rim area making hermetic sealing difficult
Solution Approach 1:
The receiving element is divided into base and cover elements that can move relative to each other. This segmentation allows the application tube to maintain its position for easy injection molding while the cover element can be opened to provide access to the sealing rim for precise sealing operations.
Solution Approach 2:
The cover element acts as an intermediary that can be opened to provide access to the sealing rim area. This intermediary structure allows the application tube to remain in its manufactured position while enabling precise sealing operations to occur through the opened cover element.

AI summary
The invention relates to a filling and closing device (20) for an applicator for active substances (1) and to a method for filling and closing such an applicator for active substances (1) by means of such a filling and closing device (20). The applicator for active substances (1) comprises an applicator tube (7) that overlaps the sealing edge (5), at least in part. The filling and closing device (20) comprises a receiving element (21) for the lower part (2) of the applicator for active substances (1), having a circumferential pressure surface (22) and a receiving channel (23) for the applicator tube (7), said receiving channel extending below the pressure surface (22). The receiving element (21) is constructed of at least two parts, having a base element (24) and a cover element (25) that is movable with respect to the base element (24). After completion of the filling and sealing process, the cover element (25) is moved relative to the base element (24), such that the receiving channel (23) formed therebetween is exposed. The filled and sealed applicator for active substances (1) can then be easily removed from the receiving element (21) by way of the applicator tube (7).
