Solution Overview

Problem

Existing containers require separate application tools, which are inconvenient to carry and can lead to contamination, and integrated tools with circular sections limit application area and amount adjustment.

Innovation Solution

A container with a cap integrated application tool and a rotatable wiper that includes a scraping portion and enlarged passages, allowing the tool to be mounted on the cap without separate carrying and enabling adjustable content application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate application tool is used to take content out of the container, then the content can be applied, but the user has to carry an additional tool and contamination risk increases

Engineering Contradiction:
Improveconvenience of useVSAvoidnumber of components to carry
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The application tool is merged with the cap of the container, forming an integrated assembly. The cap serves both as a closure for the container and as a holder for the application tool, eliminating the need to carry separate tools while reducing contamination risk through enclosed storage.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If the application tool has a circular section to be coupled to the container, then it can be mounted, but the application area is limited and amount adjustment is restricted

Engineering Contradiction:
Improveapplication areaVSAvoidcoupling mechanism constraints
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The application tool features a non-circular cross-section that corresponds to a matching non-circular opening in the cap. This asymmetric design provides unique orientation and secure coupling while allowing for varied application surfaces and improved adaptability to different content types and application areas.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The coupling mechanism between the application tool and cap allows for rotational movement and adjustable positioning. The tool can be rotated to different angles and positions within the cap, enabling dynamic adjustment of the application area and amount of content dispensed.

Inventive Principle:
Principle #15Dynamics

AI summary

The present invention relates a content container including an application tool and, more specifically, to a container which has an application tool coupled to a cap thereof and thus enables a user to take and apply a content thereof without a need to carry a separate tool. According to an embodiment of the present invention, a container may include: a container body in which a content is received; a cap including an application tool for applying the content; and a wiper having a through-hole formed therethrough, through which the application tool is to be inserted, wherein the wiper includes: a scraping portion for wiping off at least a portion of content attached onto the application tool; and enlarged portions for allowing the content attached on at least a portion of the application tool to pass therethrough.
