Dual Compartment Container With Puncture Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multiple compartment containers are complex and expensive to produce, limiting their design and volume options, and generate multiple disposable parts that are not environmentally friendly.
Innovation Solution
A container design featuring two separate container bodies connected by an interface device with a puncturable membrane, allowing easy mixing of contents without the need for separate lids or parts, produced using blow molding technology for cost-effectiveness and versatility in shape and size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple compartment containers are designed with separate closures and containers for each component, then the separate storage and distribution of components is achieved, but the number of disposable parts increases and environmental friendliness deteriorates
Solution Approach 1:
The patent merges multiple container bodies into a single integrated packaging structure that maintains separate compartments for different components. The container bodies are connected through a bottom wall with an opening, allowing components to be stored separately while using a single unified package that reduces disposable parts and waste generation.
2Manufacturing precision
If injection molding is used to create high accuracy fastening structures, then the sealing and fastening precision is improved, but the production cost and complexity increase
Solution Approach 1:
The patent segments the container structure into distinct components including multiple container bodies, a bottom wall with opening, and a closure member. This segmentation allows each component to be manufactured using suitable processes and assembled together, reducing production complexity while maintaining fastening accuracy through designed engagement features.
Solution Approach 2:
The closure member serves multiple functions: it closes the opening in the bottom wall, provides fastening structures for securing container bodies, and maintains sealing integrity. This multi-functionality reduces the need for separate specialized components, simplifying production while maintaining precision.
3Ease of manufacture
If a flared side wall shape is used for demolding, then the ease of manufacturing is improved, but the design flexibility and volume options are limited
Solution Approach 1:
The patent addresses the demolding constraint by designing the container bodies with appropriate dimensional characteristics that facilitate release from molds. The segmentation into separate bodies connected by a bottom wall allows each component to be molded independently with optimized shapes, then assembled, thereby maintaining design flexibility while ensuring manufacturability.

AI summary
The container (10) is suitable for the separate packaging and storage of at least two contents, which need to be combined in the preparation of a ready-to-use product. Two container bodies (1, 2) are assembled by using an interface device (3) as intermediate connecting means. A first connector (31 ) and a second connector (32) are used to form the device (3). A mixing mechanism is formed when coupling an inserting part of one of the connectors (32) with an annular bearing portion of the ther connector (31 ). The interface device comprises means, typically a puncturing structure (6), for releasing an internal passage (4) initially sealed by a closure member (5), allowing communication between a first compartment (C1 ) and a second compartment (C2). The respective connectors (31, 32) are thermoplastic pieces each integrally secured to a corresponding plastic container body (1, 2), preferably by induction sealing using a metal medium.
