Pressable Container One-Way Valve to Reduce Material Remnants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressable containers, such as tubes for creams and sauces, often leave remnants due to inefficient ejection methods, where users cannot ensure all material is utilized without external devices or multiple holding positions.
Innovation Solution
The implementation of one-way conduction valves within pressable containers that switch between conducting and non-conducting states to facilitate complete ejection of materials without external assistance, ensuring all contents are used by preventing backflow and optimizing ejection through multiple valve positions.

Engineering Contradiction Analysis
1Quantity of substance
If users press the container and hold it in different positions to eject cream, then some cream can be ejected, but remnants are left inside and full utilization cannot be achieved
Solution Approach 1:
The valve mechanism automatically switches between conducting and non-conducting states based on pressure direction, eliminating the need for external devices or complex user maneuvers. The system serves itself by using the natural pressing action to activate the valve, which then prevents backflow automatically, ensuring complete material ejection without remnants.
Solution Approach 2:
The valve transitions between two dynamic states: conducting state when pressed from the bottom (allowing cream ejection) and non-conducting state when held in other positions (preventing backflow). This dynamic state change based on pressure direction ensures complete material utilization by adapting the valve function to the container's orientation and pressing direction.
2Quantity of substance
If a valve is added to enable one-way conduction, then full utilization of material is achieved, but the device complexity increases
Solution Approach 1:
The valve is divided into two functional segments: a conducting portion that allows flow in one direction and a non-conducting portion that prevents backflow. This segmentation enables the valve to perform multiple functions (ejection facilitation and backflow prevention) within a single integrated component, achieving complete material utilization without excessive complexity.
Solution Approach 2:
The valve changes its conduction parameter based on pressure direction. When pressure is applied from the bottom, the valve transitions to a conducting state with high permeability. When pressure is applied from other directions or the container is held in different positions, the valve transitions to a non-conducting state. This parameter change allows simple structural design to achieve complex functional behavior.

AI summary
A one-way valve adapted to be provided in a pressable container from which material is ejected wherein the valve includes: two adjacent tongues extending from a circumference of the pressable container, wherein the two adjacent tongues have two states: a first state wherein the tongues are not folded on a fold line, thereby the material passes between the tongues; and a second state wherein the tongues are folded on the fold line and prevent passage of material through them; and an opening, for ejecting the material therethrough at the first state, wherein the opening is disposed above the fold line at the first state, and below the fold line at the second state.
