Punch with Relief Patterns for Hollow Glass Decoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method and device to manufacture hollow glass articles, such as bottles or jars, that allow for the creation of personalized decorations in relief or hollow patterns inside the glass, independent of the article's shape, to enhance branding and product recognition in the perfumery and cosmetics industry.
Innovation Solution
A method and device that involve a mold with a ring mold and a punch with a frustoconical end part having raised or recessed patterns, allowing the punch to form the glass article while simultaneously printing the patterns on the internal face, using a guide sleeve for precise positioning and a cooling element for efficient glass shaping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a punch is used to form the glass article, then the article acquires its final shape, but additional steps are required to add internal decorations
Solution Approach 1:
The patent combines the forming function and decoration function into a single punch tool. The punch includes both a frustoconical end part for shaping the glass and raised or recessed patterns on its cylindrical part for creating internal decorations. This merging of functions allows simultaneous formation and decoration in one operation, eliminating the need for separate decoration steps and improving manufacturing efficiency.
2Adaptability or versatility
If patterns are added to the punch, then internal decorations are created, but the punch design becomes more complex
Solution Approach 1:
The punch is divided into distinct functional segments: a frustoconical end part for forming the glass article shape and a cylindrical part with raised or recessed patterns for creating internal decorations. This segmentation allows each part to perform its specific function independently while maintaining overall simplicity. The patterns are added as surface features on the cylindrical segment rather than complex internal structures, preserving manufacturing ease.
3Manufacturing precision
If the punch projects into the mold cavity, then the article is formed with internal patterns, but the ring mold must be positioned precisely
Solution Approach 1:
The patent introduces a ring mold as an intermediary component positioned at the lower part of the mold cavity. This ring mold serves as a guide and support structure that enables precise positioning of the punch during the forming operation. The ring mold's central opening allows the punch to pass through while its structure provides reference surfaces for accurate alignment, ensuring consistent pattern positioning without requiring complex positioning mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the formation of hollow glass articles with internal relief or hollow patterns in a single operation, allowing for customized designs that enhance branding and product recognition, while maintaining the elasticity of molten glass for easy release.
Implementation Method 1
a punch comprising at least one pattern in relief and/or in hollow is introduced into the impression
Implementation Method 2
a cooling element for efficient glass shaping

AI summary
The device includes a mold (20) having an impression (21) of shape corresponding substantially to the external shape of the glass article (1) and a punch (10) movable between a passive position outside the impression (21) and an active position inside this impression (21) and including a hollow body having on at least one external face at least one pattern (15) in relief and/or intaglio.
