Neckless Cosmetic Bottle With Lateral Closure Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The presence of a neck with smaller cross-sectional dimensions in cosmetic product bottles limits the size of applicators that can be used, as manufacturers seek to offer larger applicators without increasing the overall dimensions of the bottle.
Innovation Solution
The opening and closing means are positioned at a distance from the proximal and distal ends of the bottle, allowing for a neckless design that enables larger applicators to be used without increasing the bottle's overall dimensions, using a screwing, bayonet, or clipping system for sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a neck with smaller cross-sectional dimensions is present in the bottle, then the overall dimensions of the bottle body can be kept small, but the size of applicators that can be used is limited
Solution Approach 1:
The invention removes the neck structure from the bottle design, extracting the constraining element that limited applicator size. By eliminating the neck and its associated opening/closing mechanisms from the bottle body, the opening can be enlarged to accommodate larger applicators while maintaining a compact bottle body volume.
Solution Approach 2:
The opening and closing means are repositioned from the traditional neck location to the lateral wall of the bottle body, changing the spatial dimension where the sealing mechanism operates. This allows the opening to be larger while the closing mechanism acts on a different plane (lateral wall), resolving the conflict between opening size and bottle compactness.
2Area of moving object
If the opening of the bottle is enlarged to accommodate large applicators, then larger applicators can be used, but the overall size of the bottle increases
Solution Approach 1:
The closing mechanism is relocated from the axial direction (neck) to the lateral wall, allowing the bottle opening to be enlarged in the axial direction without increasing bottle dimensions in other directions. The closing means operate on the lateral surface, decoupling the opening size from the overall bottle footprint.
Solution Approach 2:
The bottle structure is segmented into distinct functional zones: the body containing the product, the lateral wall housing the closing mechanism, and the enlarged opening for applicator insertion. This segmentation allows each component to be optimized independently, with the opening maximized for applicator access while the body remains compact.
3Reliability
If opening and closing means are located at the neck, then a tight seal can be ensured, but the applicator size is limited by the neck cross-section
Solution Approach 1:
The opening and closing means are extracted from the neck location and repositioned to the lateral wall of the bottle body. This removes the constraint where the closing mechanism had to operate within the limited neck cross-section, allowing both a tight seal and a larger opening for applicators.
Solution Approach 2:
The lateral wall acts as an intermediary surface for the closing mechanism, providing a larger area for sealing operations away from the bottle opening. This intermediate location allows the closing means to ensure tight sealing without constraining the opening size needed for large applicators.
