Container for viscous liquid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containers for viscous liquids like caramel are difficult to control, leading to inconvenience in handling and preparation, as the viscous liquid adheres to the container walls, attracting dirt, dust, and insects, and the flow is slow, compromising food safety and sanitation.
Innovation Solution
A container design featuring a flexible main body with a one-way valve and flow control valve, allowing controlled dispensing of viscous liquids by applying force to deform the dome-shaped one-way valve and utilizing air pressure to return to the original state, preventing wall attachment and ensuring easy pouring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container is tilted to make caramel flow out, then the caramel can be dispensed, but the amount of caramel poured out is difficult to control
Solution Approach 1:
The patent employs a flexible main body that can be dynamically compressed by hand pressure to control caramel flow. The deformation of the flexible body creates pressure to push caramel through the one-way valve, allowing precise control of dispensing amount through dynamic manual compression rather than static tilting
Solution Approach 2:
The one-way valve acts as an intermediary mechanism between the flexible main body and the dispensing opening. It allows caramel to flow outward when pressure is applied but prevents backflow, enabling controlled unidirectional dispensing and precise control of the amount poured out
2Ease of operation
If the container is tilted for caramel flow, then caramel can be poured out, but caramel flows attach to and move vertically along the outer wall of the container
Solution Approach 1:
The invention extracts the caramel flow path from the container outer wall by using an inner dispensing channel formed by the flexible main body. Caramel flows through the internal space and exits through the opening at the bottom, completely separating the flow path from the outer wall surface, thus eliminating wall attachment
Solution Approach 2:
The flexible main body forms an internal channel that guides caramel flow away from the outer wall. The flexibility allows the body to deform under compression, pushing caramel through the internal path and preventing contact with the external container surface
3Loss of time
If the container is used for a while, then the amount of caramel decreases, but it takes longer to wait for caramel to flow from the bottom side to the opening
Solution Approach 1:
The flexible main body maintains dynamic responsiveness throughout use. Even as caramel quantity decreases, hand compression continuously generates pressure to push remaining caramel toward the opening, maintaining consistent flow speed and preventing the increased waiting time that would occur with static containers
4Object-affected harmful factors
If caramel is not cleaned completely after use, then food safety and kitchen sanitation problems occur, but the container design should prevent this
Solution Approach 1:
The invention extracts the caramel flow path from the outer wall and confines it to an internal channel formed by the flexible main body. This separation means caramel never contacts the outer wall surface, eliminating the cleaning problem entirely - the exterior remains clean while the interior channel can be easily rinsed
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 allows for precise control of viscous liquid output, preventing wall attachment and enhancing food safety and sanitation by facilitating quick and clean dispensing, reducing the risk of contamination and attracting pests.
Implementation Method 1
a dome is set under a central hole thereof and used for closing the central hole. The dome is projecting toward an inner side of the central hole and is arranged with a gap
Implementation Method 2
External air flows through the gap between the flow control valve and the second cover to push and move the flexible piece of the flow control valve for entering into the main body when the force applied is released. Thus the main body is turned back to the original shape

AI summary
A container for viscous liquid is revealed. A first cover set with a one-way valve and a second cover arranged with a flow control valve are disposed on two ends of a main body of the container respectively. The first cover is suspended on a supporting member. Thereby a force is applied to the main body for pouring out viscous liquid such as caramel. Thus caramel pushes against a dome of the one-way valve and a gap on the dome is opened to make the caramel out. Once no force is applied, external air flows through a gap between the flow control valve and the second cover to push a flexible piece of the flow control valve and enter the main body. Thus both the main body and the dome of the one-way valve return back to the original shape. Thereby the caramel can be handled easily.
