Multi-compartment dispensing package with frangible tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-compartment dispensing packages face challenges in ease of assembly and functionality, particularly in separating and accessing individual compartments efficiently.
Innovation Solution
A square-profile dispensing package with a cover sheet and base member, featuring frangible separation lines, adhesive closure members, and foldable tabs, allowing for easy separation and access to compartments while maintaining sealed units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If frangible separation lines are used to connect compartment units, then ease of separation is improved, but structural strength deteriorates
Solution Approach 1:
The base member is divided into multiple compartment units that are connected by frangible separation lines, allowing the package to be segmented into individual compartments for easy separation and access to contents
2Reliability
If adhesive closure members are used to seal compartments, then reliability of sealing is improved, but ease of opening deteriorates
Solution Approach 1:
The closure member is pre-applied with adhesive to seal the compartment, but includes a perforated lift tab that allows easy initiation of opening by pulling the tab, which then facilitates easy peeling of the entire closure member
Solution Approach 2:
The lift tab acts as an intermediary element between the user's finger and the adhesive closure member, providing a non-adhesive grip point that enables easy removal of the sealed closure member without directly contacting the adhesive surface
3Quantity of substance
If multiple compartment units are connected in an array, then quantity of storage is improved, but device complexity deteriorates
Solution Approach 1:
Multiple compartment units are merged into a single integrated base member with a common frangible separation line network, allowing multiple compartments to be connected and separated as a unified structure rather than individual separate packages
Solution Approach 2:
The base member serves multiple functions: it provides structural support for multiple compartments, contains the adhesive closure member array, and includes frangible separation lines that enable various separation patterns (individual compartments or groups), making it a multi-functional integrated package
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 solution enables efficient separation and access to individual compartments, improving usability and assembly ease while ensuring sealed units remain secure until needed.
Implementation Method 1
The closure member has an adhesive layer on its undersurface for releasably securing the closure member to the flange of the compartment unit
Implementation Method 2
The flanges of the multi-compartment base are detachably connected along frangible separation lines connecting the corners so that each compartment unit may be separated from the other compartment units

AI summary
A multi-compartment package for dispensing plural items is disclosed. The package includes plural individual sealed compartment units which are releasably secured to each other. Each compartment unit includes a flanged base from which a chamber depends. The chamber serves to hold an item to be dispensed and is surrounded by a flange. A closure member, in the form of a respective portion of a frangible cover sheet, is adhesively secured to the flange of each compartment unit. Each compartment unit includes at least one foldable tab in a corner of its flange, which can be folded down to enable the closure member to be removed from the compartment unit after the compartment unit is separated from other compartment units of the package.
