Inverted Bottle Bottom Design for Deformation Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content filling bottle designs face challenges with reduced pressure deformation, material costs, and sanitation issues during hot and aseptic filling processes due to the need for auxiliary tools and complex bottle shapes.
Innovation Solution
A method and device for producing a content filling bottle with a synthetic resin bottle featuring a hollow body, an inversion part that projects outwardly and can be recessed inwardly, where the auxiliary tool is installed after sealing, allowing for efficient filling and sealing operations without compromising sanitation or stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inversion part of the bottom part is projected outwardly before filling to prevent reduced pressure deformation, then the deformation prevention function is improved, but the bottle becomes unstable and cannot stand on its own
Solution Approach 1:
A support member is introduced as an intermediary element between the bottle and the support surface. The support member has a support portion that contacts the support surface and an accommodation portion that receives the inverted bottom part of the bottle, enabling the bottle to stand stably even when the inversion part projects outwardly
Solution Approach 2:
The support member creates a complementary structure that mirrors the inverted bottom part geometry, providing a matching accommodation portion that perfectly receives the inverted inversion part, ensuring stable support and easy placement
2Stability of the object's composition
If a cylindrical auxiliary tool is installed in the bottom part to assist self-standing, then the stability is improved, but sanitation is compromised during hot filling due to washing water contamination
Solution Approach 1:
The support member is designed with a removable configuration that allows it to be installed on empty bottles before filling, and then easily removed after filling and sealing, preventing contamination during the washing process while maintaining stability during handling and transport
Solution Approach 2:
The support member is temporarily attached to the bottle during the filling process for stability, then removed and reused for the next bottle, eliminating sanitation issues while maintaining the stability benefit during critical operations
3Stability of the object's composition
If the auxiliary tool remains installed in the bottle for aseptic filling sterilization, then the stability is maintained, but the number of operation steps increases reducing efficiency
Solution Approach 1:
The support member is designed to be self-contained with integration features that allow automatic or semi-automatic attachment and detachment, reducing manual intervention and enabling the system to handle its own support member management without additional complex mechanisms

AI summary
The present invention provides a method and device for producing a content filling bottle including a bottom part that is inverted between a concave shape and a convex shape to prevent a body part from being subjected to reduced pressure deformation, the method and device being capable of efficiently producing a sanitary and high-quality content filling bottle. Contents are filled into an empty bottle 1 with an inversion part 11 projecting outwardly from the body part. A cap 6 is fitted onto an opening of the bottle 1 to seal the bottle 1. An auxiliary tool 27 is then installed on the bottom part 5 of the bottle 1. Then, the bottom part of the bottle 1 with the auxiliary tool 27 installed thereon is supported via the auxiliary tool 27. The downwardly projecting inversion part 11 is pressed up so as to be inverted and recessed inwardly into the bottle 1. Subsequently, with the opening of the bottle 1 gripped, the auxiliary tool 27 is separated from the bottle 1.
