Hose-Free Spray Container With Partitioned Internal Flow Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid containers with pumps for dispensing contents, such as cosmetic bottles, often have an aesthetic issue due to the visible hose connecting the pump to the container, which can be mitigated by omitting the hose through an improved channel structure.
Innovation Solution
A container design featuring a body with a partitioned outflow channel, a body cover, a pump support, and a shoulder that allows for the pump to be directly coupled without a hose, maintaining pressure through external air inflow to ensure efficient dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hose is used to connect the pump to the container, then the pump can effectively draw liquid content, but the overall aesthetic of the container is lowered due to the visible hose
Solution Approach 1:
The patent removes the hose from the system by integrating the outflow channel directly into the container body. The partition wall creates an internal channel that eliminates the need for external hoses, thereby maintaining aesthetic appearance while preserving pump functionality.
Solution Approach 2:
The patent merges the outflow channel function directly into the container body structure. By forming the channel through the partition wall of the container body, the patent combines what were previously separate components (hose and container) into a unified structure.
2Object-affected harmful factors
If the container body is made from opaque material, then the hose may not be seen from the outside, but the aesthetic appeal is reduced compared to transparent materials
Solution Approach 1:
The patent eliminates the hose entirely by integrating the outflow channel into the container body structure. This removes the need for opaque materials to hide the hose, allowing the container to be made from aesthetically pleasing transparent or translucent materials without compromising the hidden hose issue.
3Device complexity
If a partition is provided in the container body, then the outflow channel can be formed without a hose, but the structural complexity increases
Solution Approach 1:
The patent divides the container body into different functional zones using a partition wall. This segmentation creates the outflow channel while maintaining a relatively simple overall structure that can be manufactured using conventional molding techniques, balancing structural functionality with manufacturing ease.
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 design provides a simplified structure with improved aesthetics by eliminating the visible hose while maintaining effective dispensing of liquid contents, even when made of transparent materials.
Implementation Method 1
the content that was previously drawn into the pump may be pressurized, moved up along the discharge path
Implementation Method 2
the suctioning force of the pump may be applied on the inside of the hose, allowing the content held in the body to be drawn in through the hose and into the pump
Implementation Method 3
the content that was previously drawn into the pump may be pressurized, moved up along the discharge path
Implementation Method 4
sprayed through the nozzle

AI summary
A container for spraying liquid includes a body, a body cover, a pump, a pump support, and a shoulder. The body includes a filling space and a body outflow channel which has a smaller cross-sectional area compared to the filling space due to a partition. A content injected into the filling space enters the body outflow channel at a lower portion of the partition, and an upper body hole is formed at an upper portion of the partition as an exit from the body outflow channel. The body cover is coupled to an upper portion of the body and includes a cover channel communicating with the upper body hole and a pump insertion space communicating with the cover channel. The pump is inserted in the pump insertion space, and the pump support is coupled to an upper portion of the body cover to support the pump. The shoulder is coupled to an upper portion of the pump support to press the pump support downward.
