Fluid Container Transition Angle Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container designs for fluid products, such as shampoos and cosmetic creams, require high amounts of raw materials and result in large overall dimensions due to the need for a high collar to cover the truncated cone-shaped terminal area, leading to increased costs and a risk of the cap coming off when squeezed.
Innovation Solution
A container design with a reduced transition area angle (between 75° and 85°) and a snap-in cap connection, which reduces the height of the cap's collar and the overall dimensions, while maintaining mechanical resistance and preventing cap detachment during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the collar height is increased to cover the truncated cone-shaped terminal area, then the mechanical resistance and cap retention are improved, but the raw material usage and overall dimensions increase
Solution Approach 1:
The patent changes the geometric parameters of the transition area by reducing the inclination angle to between 75° and 85°, which allows the collar to be shorter while still providing adequate coverage and mechanical resistance. This parameter optimization resolves the contradiction between needing sufficient collar height for strength and minimizing material usage.
2Strength
If the collar height is increased to cover the truncated cone-shaped terminal area, then the mechanical resistance and cap retention are improved, but the overall dimensions of the unit increase
Solution Approach 1:
By optimizing the inclination angle of the transition area to between 75° and 85°, the patent achieves sufficient mechanical resistance with a reduced collar height, thereby minimizing the overall length of the container-cap unit while maintaining structural integrity.
3Productivity
If the inclination angle of the transition area is increased to favor product flow, then the dispensing efficiency is improved, but the collar height must be increased to cover the area
Solution Approach 1:
The patent optimizes the inclination angle within the range of 75° to 85°, which provides a balanced solution: the angle is sufficiently high to favor product flow from the inside towards the dispensing hole, yet low enough to allow the collar to cover the transition area with minimal height, thus avoiding increased overall dimensions.

AI summary
The present invention concerns a container (1; 71; 121; 201) for a fluid product, comprising: a main body (2; 72; 122) suited to define an inner area (3) suited to contain the product, the main body (2; 72; 122) ending with an edge (6; 126) in a terminal area (5; 125) of the container (1; 71; 121; 201); an opening (7) for dispensing the product associated with the terminal area (5; 125) of the container (1; 71; 121; 201); connection means (8) suited to allow the coupling of a closing element (50; 80; 90; 100; 110) for the opening (7), the connection means (8) comprising a projecting portion (9) that extends longitudinally along a main axis (X) from a base area (10) associated with the terminal area (5; 125) of the container (1; 71; 121; 201); a transition area (2; 212) suited to connect the edge (6; 126) of the main body (2; 72; 122) to the base area (10) of the connection means (8). At least one portion of the edge (6; 126) of the main body (2; 72; 122) and at least one portion of the base area (10) of the connection means (8) are crossed by an inclined axis (Z) that together with the main axis (X) of the projecting portion (9) defines an angle (A) included between 70° and 90°.
