Solution Overview

Problem

Existing container caps for storing grain-type supplementary contents are complicated to manufacture and inconvenient to recycle due to internal contamination, as they require multiple coupled members.

Innovation Solution

A container cap with a simplified structure featuring a cap body and an upper lid, where the upper lid includes a pushing part that fractures an outlet plate by vertical movement, allowing easy drinking and recycling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a container cap with multiple coupled members is used to store grain-type supplementary contents, then the functionality is improved, but the manufacturing complexity increases and recycling becomes inconvenient

Engineering Contradiction:
ImprovefunctionalityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple previously separate components (cap body, lid, and supplementary content storage) into a single integrated container cap structure. The grain-type supplementary contents are stored within the cap body itself, eliminating the need for separate storage chambers or additional coupled members, thereby simplifying manufacturing while maintaining functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The container cap is designed to perform multiple functions within a single structure: it seals the container, stores grain-type supplementary contents, and allows for easy opening and closing. The integrated design enables the cap to serve as both a sealing mechanism and a storage container, reducing the need for multiple specialized components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a container cap with multiple coupled members is used to store grain-type supplementary contents, then the functionality is improved, but recycling convenience deteriorates due to internal contamination

Engineering Contradiction:
ImprovefunctionalityVSAvoidrecycling convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

By integrating the storage function directly into the cap body rather than using separate coupled members, the patent creates a single-component structure that can be easily separated from the container. This eliminates the risk of internal contamination between multiple members during recycling and allows for straightforward disposal or reuse of the entire cap assembly.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If a container cap with multiple coupled members is used, then specific functions are achieved, but coupling with the container becomes inconvenient

Engineering Contradiction:
ImprovefunctionalityVSAvoidcoupling convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines all functional elements into a single integrated cap structure that couples with the container as one unit. This eliminates the need for multiple coupling interfaces between separate members, simplifying the coupling process and reducing the risk of misalignment or improper assembly.

Inventive Principle:
Principle #5Merging (Combining)

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 cap enables convenient consumption and recycling by forming a discharge hole through vertical movement of the pushing part, maintaining an integrated structure without separation from the container inlet.

Implementation Method 1

an elastic deformation part 212 configured to couple the pushing part 210 with the upper lid 200 so as to be movable vertically with respect to the upper lid 200

Methodology Applied
Scientific EffectElastic deformation: Elasticity

AI summary

The present invention relates to a container cap and, more specifically, to a container cap coupled to a container inlet, and a container to which same is coupled. Disclosed is the container cap comprising: a cap body (100) coupled to a container inlet (12) of the container (10) in which contents are contained; and an upper lid (200) coupled to the cap body (100) to cover the upper side of the cap body (100), wherein the cap body (100) includes an outlet plate (110) which is fractured from an upper plate part (101) to form a discharge hole (102) through which the contents contained in the container (10) are discharged, and the upper lid (200) includes a pushing part (210) which is formed in correspondence to the outlet plate (110) and which fractures the outlet plate (110) by means of the vertical movement thereof.
