Solution Overview
Problem
Existing containers face issues with inconsistent external force required for deformation and varying shapes of the container body, leading to unpredictable discharge amounts and concentrations of contents, making it difficult to achieve a constant concentration of the diluted product.
Innovation Solution
The container features a deformation controlling recess with a progressively reduced width from the back face to the bottom face, ensuring consistent deformation and discharge, along with a reverse-oriented annular seal portion for precise detachment and smooth content flow, allowing for constant concentration and reduced residual contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the container body is deformed by external force to discharge contents, then the contents can be discharged from the container, but the external force required is not constant and the deformation shape varies, leading to inconsistent discharge amounts
Solution Approach 1:
The patent applies local quality by creating a deformation controlling recess with specific geometric characteristics (progressively reduced width from back face to bottom face) at a localized position on the container body. This localized structural feature ensures that deformation always initiates at the same position and follows a consistent path, making the discharge amount reliable and repeatable regardless of variations in applied external force.
Solution Approach 2:
The deformation controlling recess is pre-formed during container manufacturing, establishing the exact location and geometry where deformation will occur during use. This preliminary preparation ensures that when external force is applied, the container body deforms in a predictable and consistent manner, achieving reliable discharge amounts without requiring precise control of the external force magnitude.
2Quantity of substance
If the external force is increased to ensure complete discharge of contents, then more contents can be discharged, but the deformation shape becomes inconsistent and the force required varies
Solution Approach 1:
By concentrating the deformation control function in a specifically designed recess structure with progressively reduced width, the patent ensures that deformation follows a predetermined path regardless of the magnitude of external force applied. This allows complete discharge of contents while maintaining consistent deformation behavior and avoiding unpredictable shape changes.
3Shape
If the container body is made more rigid to maintain shape, then the deformation shape remains constant, but the external force required for deformation increases
Solution Approach 1:
The patent creates a localized deformation controlling recess with progressively reduced width that acts as a controlled weak point. This allows the rest of the container body to maintain its rigid structure for shape consistency, while the specific recess area deforms predictably under external force, achieving both shape consistency and manageable force requirements.
Solution Approach 2:
The container body structure is effectively segmented into a rigid outer structure and a localized deformable recess region. This segmentation allows the majority of the container to maintain its shape and rigidity, while the specific recess portion is designed to deform in a controlled manner, achieving both shape consistency and ease of deformation.
4Quantity of substance
If the deformation starts from the back face side, then the structure is simpler, but the deformed side wall may interfere with the lid member and prevent complete discharge
Solution Approach 1:
Instead of allowing deformation to start from the back face side as in conventional designs, the patent inverts the approach by designing the recess with progressively reduced width from back face to bottom face, causing deformation to initiate at the bottom face side. This inversion ensures the deformed side wall moves away from the lid member, preventing interference and enabling complete discharge, while the recess structure itself remains relatively simple.
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
This design enables consistent deformation with a small external force, ensuring constant content discharge and achieving a stable concentration of the diluted product, while minimizing residual contents and preventing interference from the deformed side wall.
Implementation Method 1
when the container body receives an external force from the bottom face, the stress tends to be concentrated at the end portion of this deformation controlling recess which portion has smallest width and is offset towards the bottom face
Implementation Method 2
a detaching seal portion which is detached in response to increase of pressure inside the container body associated with deformation of the container body

AI summary
Provided is a container with which its body can be deformed with a same external force until most of the contents has been discharged from the container body and to cause the final shape after the deformation to be a constant shape. Also provided is a container with which the contents discharged can be rendered constant, thus making it possible to obtain a diluted product having a constant concentration. The container includes a bottomed container body and a lid member, the container body and the lid member being sealed by an annular seal portion. There is provided a detaching seal portion which is detached in response to increase of pressure inside the container body associated with deformation of the container body. There is also provided a deformation controlling recess whose width is progressively reduced from a back face side of the flange toward the bottom face side.
