Decorative Bottle Cap Attachment for Reduced Neck Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle assemblies with aesthetic collars have external dimensions that are relatively large due to the attachment of the aesthetic fret to the neck, which results in bulkiness and inefficient integration, particularly in rectangular or square cross-section designs.
Innovation Solution
A bottle assembly with a neck featuring rounded corners and indentations, an aesthetic collar with specific fastening systems, including internal and external clamping means, anti-fluttering means, and centering mechanisms, to reduce thickness and improve integration by securing the collar only at the corners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the aesthetic collar is attached to the neck using a conventional fastening system, then the attachment is secure, but the external dimensions and thickness around the neck become relatively large
Solution Approach 1:
The fastening system is segmented into four separate attachment points (lugs) positioned at the corners of the rectangular neck, rather than a continuous rim. This segmentation allows the aesthetic collar to be secured firmly at critical points while eliminating material and thickness in the intermediate regions, thus resolving the contradiction between secure attachment and reduced thickness.
Solution Approach 2:
The neck cross-section is designed with non-uniform thickness: thicker at the corners where lugs are positioned for secure attachment, and thinner at the mid-points between corners. This local variation in quality optimizes both attachment security at critical locations and overall thickness reduction for aesthetic purposes.
2Reliability
If the aesthetic collar completely encompasses the rim and attachment means, then the attachment is secure, but the external dimensions increase
Solution Approach 1:
The aesthetic collar encompasses only the four corner lugs rather than a complete continuous rim. This partial action provides sufficient attachment reliability at the critical corner positions while significantly reducing the external dimensions and material required compared to a full circumferential attachment system.
3Shape
If the neck has a rectangular section for aesthetic reasons, then the aesthetic appearance is improved, but the integration with the fastening system becomes less efficient
Solution Approach 1:
The functional elements (fastening lugs) and aesthetic elements (rectangular neck shape with rounded corners) are merged into a single integrated design. The rectangular cross-section with rounded corners serves both aesthetic purposes and provides natural corner positions for the lugs, eliminating the need for separate attachment structures and simplifying the overall integration.

AI summary
The invention relates to an assembly (200) comprising: - a bottle (102) having a rectangular neck (114), where each corner has a depression (116); - a decorative cap (104) positioned on the neck (114) and comprising a first plate (104a) through which a first window (104b) extends, and a first outer skirt (104c); - an attachment system (208) comprising a second plate (208a) through which a second window (208b) extends and which is positioned between the neck (114) and the first plate (104a); - four lugs (208c) secured to the second plate (208a), where each lug (208c) is positioned under one of the shoulders of the neck (114); and - attachment means (250) which fasten the decorative cap (104) to said attachment system (208). With such an arrangement, the attachment system has a special shape which makes it possible to reduce thicknesses around the neck.
