Solution Overview
Problem
Existing technologies fail to adequately protect cosmetic contents from environmental factors such as retinol, vitamins, etc., are prone to chemical changes due to external environments, such as retinol, vitamins, etc., are included in the contents, the contents may be deteriorated due to exposure to light, oxygen, moisture, etc., during the distribution, storage, and other processes of cosmetic containers, the dropper-type cosmetic containers have a limitation in that it is insufficient to solve the problem of the contents may be deteriorated by external environments, the dropper-type cosmetic technologies have a limitation in that it is insufficient to protect the contents from being effectively sealed from being deteriorated by external environments.
Innovation Solution
A content container with a container body, neck portion, discharge portion, shoulder portion, and overcap, where the discharge portion descends from a first to a second position by external force, exposing a communication hole to transfer contents via a nozzle portion, and is sealed by coupling protrusions and grooves, preventing leakage and deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a dropper-type or tube-type cosmetic container is used, then the contents can be discharged conveniently, but the contents are exposed to external environments (light, oxygen, moisture) during storage and distribution, causing deterioration
Solution Approach 1:
The container is divided into separate functional parts: a container body for storage, a discharge portion with communication hole for controlled discharge, and a neck portion with sealing structure. This segmentation allows the sealing function to be independent from the discharge function, solving the contradiction between convenient discharge and environmental protection during storage.
Solution Approach 2:
The communication hole acts as an intermediary mechanism that controls the transition between sealed and discharged states. When the discharge portion descends, the communication hole moves from a blocked position (above the opening portion) to an exposed position (below the opening portion), mediating between the sealed container and the discharge nozzle, thereby protecting contents during storage while enabling controlled discharge.
2Ease of operation
If the discharge portion is always exposed for easy discharge, then the contents can be accessed easily, but the contents are exposed to external environments causing deterioration
Solution Approach 1:
The discharge portion is designed to be movable, transitioning between a retracted position (first position) where the communication hole is blocked and a descended position (second position) where the communication hole is exposed. This dynamic structure allows the container to switch between protected storage state and accessible discharge state, resolving the contradiction between easy access and protection from deterioration.
Solution Approach 2:
The sealing structure provides localized protection at the communication hole area. The bottom of the discharge portion selectively blocks or exposes the communication hole based on its position, creating a local quality change that protects the contents when stored and allows access when discharged, without requiring the entire container structure to change.
3Object-affected harmful factors
If a sealing mechanism is added to protect contents from external environments, then the contents are protected during storage, but the structure becomes more complex
Solution Approach 1:
The sealing function is merged with the discharge portion itself rather than being a separate mechanism. The bottom of the discharge portion serves dual purposes: it seals the communication hole when retracted (protection function) and exposes it when descended (discharge function). This merging eliminates the need for additional sealing components, achieving protection without increasing structural complexity.
Solution Approach 2:
The discharge portion performs multiple functions: it serves as both the discharge nozzle and the sealing mechanism. The same component that controls content discharge also provides the sealing action by positioning the communication hole either blocked or exposed. This multi-functionality reduces the number of separate parts needed, maintaining structural simplicity while achieving effective protection.
4Reliability
If a locking mechanism is added to ensure tight sealing, then the contents are tightly sealed, but the operation becomes more complicated
Solution Approach 1:
The locking mechanism is designed to be self-actuating through the rotational motion of the overcap. When the overcap is rotated, it drives the discharge portion to descend automatically, which in turn automatically exposes the communication hole and initiates discharge. The system serves itself by converting a simple rotational input into the complex sequence of unlocking and discharge actions, maintaining operational simplicity while ensuring tight sealing during storage.
Solution Approach 2:
The coupling protrusions and coupling grooves are pre-configured in specific positions and orientations. The first coupling protrusion and first coupling groove engage to lock the discharge portion in the retracted (sealed) position, while the second coupling protrusion and second coupling groove are positioned to engage when the discharge portion descends. This preliminary configuration of coupling elements ensures that the tight sealing is automatically maintained through the mechanical design, without requiring complex active locking controls.

AI summary
A content container is provided according to one embodiment of the present invention. The content container includes: a container body accommodating content; a neck portion which is formed on the upper end of the container body and has an opening portion formed therein, the opening portion being in communication with the inside of the container body; and a discharge portion which is at least partially accommodated in the neck portion so as to seal the opening portion and has a nozzle portion for discharging the content, on the upper portion thereof. The discharge portion has at least one communication hole formed in the lower end thereof, for transferring the content in the container body to the nozzle portion. When the discharge portion is descended from a first position to a second position by the external force of a user, the communication hole is exposed to the inside of the container body so that the content in the container body can be transferred to the nozzle portion via the communication hole.
