Dispensing Container With Flexible Bottom and Chemical Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions for liquid and pasty products require pre-filling during production and often have issues with sealing and protection of the contents, as well as unsightly and aggressive injection points.
Innovation Solution
A container with a rigid body and a flexible bottom connected via chemical adhesion, where the bottom is designed to deform under manual pressure, reducing internal volume and ensuring a tight seal, and features a tamper-evident cap and oxygen-scavenging material for enhanced protection and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the body and bottom are connected by chemical adhesion, then the tightness and reliability of the seal is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent combines the bottom and body into a single integrated component through chemical adhesion, eliminating the need for separate assembly steps and ensuring a reliable seal. The bottom is chemically bonded to the body during the molding process, creating an inseparable connection that guarantees tightness while simplifying the overall manufacturing process.
2Strength
If the body is made of rigid material, then the protection and stability of the container is improved, but the ease of manufacture decreases due to injection point visibility
Solution Approach 1:
The patent applies local quality by making the bottom material opaque or colored to hide the injection point on the rigid body. The bottom serves as a local mask that conceals the unsightly injection trace while maintaining the structural integrity and rigidity of the body for product protection.
3Ease of operation
If the bottom is made flexible for manual pressure deformation, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent changes the physical parameter of the bottom material from rigid to flexible, allowing it to deform under manual pressure. This flexibility enables easy operation by finger pressure while the chemical adhesion to the rigid body ensures precise manufacturing and controlled deformation characteristics.
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
The container provides improved protection and ease of filling, with a seamless and tamper-proof connection that hides injection points, ensuring product integrity and user reassurance through a secure and aesthetically pleasing design.
Implementation Method 1
the bottom is made of a flexible material to allow the deformation of the bottom under manual pressure and in which the bottom is made so that the deformation of the bottom has the effect of reducing the internal volume of the container
Implementation Method 2
the connection between the body, made of rigid material, and the bottom, made of flexible material, is a connection by chemical adhesion

AI summary
The container (10) has a container body (20) whose end is fixed to bottom (30). A dispenser (50) is formed with an opening (52) allowing output of content from the container. A cap (40) allows closing of the opening. The body is made of rigid material e.g. non-deforming thermoplastic material, and the bottom is made of flexible material e.g. flexible thermoplastic material, to allow deformation of the bottom under manual pressure, where deformation of the bottom include effect of reducing volume of the container. Connection between the body and the bottom is chemical adhesive bond. The material for the body contains an oxygen scavenging agent to improve capacity of the container to avoid entry of oxygen inside the container.
