Solution Overview
Problem
Cream-type cosmetic containers with highly viscous contents face challenges in efficient dispensing due to complex structures, leading to increased assembly time and manufacturing costs, particularly with vacuum-type dispensers that require separate pumping members.
Innovation Solution
A cream-type cosmetic container design featuring a pumping guide cap with a button part that elastically deforms to change internal pressure, allowing for uniform content discharge without a separate pumping member, utilizing a content suctioning part and valve members to manage content flow through elastic deformation and pressure changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vacuum-type dispenser with a separate pumping member is used to discharge highly viscous contents, then the contents can be discharged effectively, but the assembling time and manufacturing cost increase due to the complicated structure
Solution Approach 1:
The invention extracts and eliminates the separate pumping member (cylinder, piston, valve body) from the dispenser system. Instead, the container body itself is designed with an integrated pumping mechanism where the cap rotates to directly compress and discharge contents, removing unnecessary components while maintaining discharge effectiveness
Solution Approach 2:
The invention merges the pumping function into the container body structure. The cap rotation motion is directly coupled to content compression and discharge through integrated structural features (inclined surfaces, pumping chambers), combining storage and dispensing functions into a unified system
2Ease of operation
If a dispenser with a cylinder, valve body, and piston is used to pump contents, then contents can be discharged through a gap, but the assembling time and manufacturing cost increase
Solution Approach 1:
The container body structure provides self-service pumping functionality through its integrated design. The cap rotation automatically creates compression and discharge cycles without requiring separate pumping components, making the system self-sufficient and reducing assembly complexity
Solution Approach 2:
The invention replaces the complex mechanical pumping system (cylinder-piston-valve) with a simpler rotational compression mechanism. The cap rotation directly compresses contents through inclined surfaces and discharge gaps, substituting elaborate mechanical components with a more efficient motion-based system
3Reliability
If a complex pumping mechanism is installed to discharge highly viscous contents, then discharge function is achieved, but manufacturing cost increases
Solution Approach 1:
The invention employs simpler, more cost-effective components that can be manufactured at lower cost. The integrated cap-and-container design uses basic structural elements rather than expensive precision pumping components, reducing manufacturing complexity and cost while maintaining functionality
Solution Approach 2:
The invention changes the operational parameters from linear piston motion to rotational cap motion. This parameter change enables the use of simpler manufacturing processes and materials, reducing production costs while achieving the same viscous content discharge effect through different mechanical action
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
Enables efficient and uniform dispensing of highly viscous contents with reduced assembly time and manufacturing costs by eliminating the need for complex pumping mechanisms, ensuring consistent discharge with each pumping operation.
Implementation Method 1
a pumping guide cap coupled to an upper portion of the container body, elastically deformed according a pressurization by a user
Implementation Method 2
a content suctioning part disposed inside the container body, coupled to a lower portion of the pumping guide cap to form a space for storing contents, and suctioning a uniform amount of contents contained in the container body by an elastic deformation of the pumping guide cap

AI summary
Provided is a cream-type cosmetic container, which can easily discharge a highly viscous content without a separate pumping member by allowing a button part to downwardly move and then return to an original location and thus changing the internal pressure of the container body when a user pressurizes the button part, and thus can save the assembling time and the manufacturing cost.
