Cosmetic Cap with Nested Inner Container for Dual Function

Solution Overview

Problem

Conventional cosmetic container caps have a single function and a common appearance, lacking innovative design or utility value, and do not allow for separate application of perfumes without opening the main package.

Innovation Solution

A cap design comprising an outer cover, inner cover, inner container, and base with threaded connections, allowing the cap to serve as both a seal and a container for cosmetics like balm or solid perfume, with a washer or parafilm to prevent overflow, and a connection sleeve for easy attachment to the container.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the cap is designed with a single sealing function, then the structure is simple, but the utility value and appearance are common and lack innovation

Engineering Contradiction:

ImprovefunctionalityVSAvoidstructure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cap is designed to perform multiple functions: it serves as a seal for the container and simultaneously as a functional container for holding additional cosmetic products such as perfume, balm, or solid perfume. This multi-functionality transforms a simple sealing component into a versatile accessory that provides both protective and storage capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The design incorporates an inner container nested within the cap structure. The inner container is positioned inside the cap's internal space, allowing the cap to hold additional cosmetic products while maintaining its primary sealing function. This nesting arrangement maximizes space utilization and enables the cap to serve dual purposes.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If the cap structure is expanded to include inner container and multiple components, then the utility value increases, but the manufacturing complexity increases

Engineering Contradiction:

Improveutility valueVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The cap is divided into distinct components including an outer cap structure and an inner container, each with specific functions. The inner container can be separately manufactured and then assembled into the cap, allowing for specialized production of each component while maintaining overall functionality. This segmentation enables flexible manufacturing approaches.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The inner container and cap are combined through threading mechanisms where the inner container features external threads that engage with internal threads in the cap. This merging creates a secure, integrated assembly that functions as a unified multi-functional unit while allowing the components to be manufactured separately using standard threading processes.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If the cap serves as both seal and container, then the surprise gift effect is achieved, but the device complexity increases

Engineering Contradiction:

Improveuser experienceVSAvoidcap structure

Core Design Contradiction:

Ease of operationVSDevice complexity

The cap is designed to perform multiple functions: it serves as a seal for the container and simultaneously as a functional container for holding additional cosmetic products such as perfume, balm, or solid perfume. This multi-functionality transforms a simple sealing component into a versatile accessory that provides both protective and storage capabilities.

AI summary

A cap. The cap comprises an outer cover, an inner cover, an inner container, and a base. The outer cover comprises an outer cover top and an outer cover body protruding from the outer cover top, and the outer cover top and the outer cover body form an inner cavity. The inner cover is set in the inner cavity of said outer cover, and a first female thread is set on the inner circumference of the inner cover body; a first male thread is set on the outer circumference of the inner container body, the first male thread matching the first female thread. The base comprises a base top and a base body protruding from the base top, a second female thread is set on the inner circumference of the base body, and the base top is connected to the inner container bottom of the inner container.
