Cuboidal Cosmetic Container Cap with Twist-Proof Corner Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for liquid cosmetic substances do not provide an aesthetically pleasing and twist-proof way to hold the container when the cap is removed, compromising the visual appeal and stability.
Innovation Solution
A cuboid container with a cuboidal shape and a cap design featuring a first receptacle for placement on the dispensing device and a second receptacle configured as a three-sided pyramid, allowing the container to be held positively and twist-proof when the cap is used as a holder, with optional weight enhancement and secure fastening means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cap is designed with a simple receptacle structure, then the manufacturing complexity is reduced, but the container cannot be held in a twist-proof manner
Solution Approach 1:
The first receptacle is designed to pass through the second receptacle, creating a nested structure where the cylindrical first receptacle is positioned within the pyramidal second receptacle. This nested configuration allows both receptacles to coexist in the cap without requiring separate cap structures, maintaining manufacturing simplicity while enabling the container to be held in a fixed, twist-proof orientation when placed in the pyramidal second receptacle.
Solution Approach 2:
The second receptacle is designed with an asymmetric pyramidal shape having four sloping sides that converge to an apex, which corresponds to the rectangular corner region of the container. This asymmetric geometry provides a unique fitting relationship that prevents the container from being placed in any orientation other than the correct one, ensuring twist-proof positioning while maintaining a relatively simple cap structure.
2Device complexity
If the first receptacle does not pass through the second receptacle, then the cap structure is simpler, but the cap cannot simultaneously accommodate both receptacles efficiently
Solution Approach 1:
The first receptacle passes through the second receptacle, creating a nested configuration where the cylindrical first receptacle is positioned within the pyramidal second receptacle. This nested structure allows both receptacles to be accommodated within the cap's volume without requiring additional cap structures, thereby maintaining relatively simple cap structure while enabling the cap to perform multiple functions: holding the dispensing device via the first receptacle and holding the container via the second receptacle.
Solution Approach 2:
The first receptacle extends in the longitudinal direction of the cap, passing through the second receptacle from one end to the other. This dimensional arrangement allows the first receptacle to occupy the longitudinal space within the cap while the second receptacle provides lateral support structure. The through-going configuration enables efficient space utilization and simultaneous accommodation of both receptacle functions within the cap's overall structure.

AI summary
A cuboidal container for storing a liquid cosmetic substance includes a neck with an opening on an upper face of the container. A dispensing device is secured to the opening. The dispensing device is a pump connected to a dispensing head and a rising line guided in the interior of the container. A cap for the container has a cap upper face with a flat surface and a cap lower face with a first receptacle adapted for placement of the cap on the dispensing device. The cap lower face as a second receptacle designed as a three-sided pyramid designed to receive one of four corner regions on a lower face of the cuboidal container so that the container is held in the second receiving area in a form fitting and rotationally fixed manner in an aesthetically pleasing position when the cap is removed and resting on a flat surface.
