Cosmetic Applicator with Radially Spaced Transfer Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging devices for cosmetics and similar products lack a simple, efficient means to apply content precisely as to size, shape, and quantity, and are often complex or unsuitable for single-use, portable applications.
Innovation Solution
A device with a radially spaced structure that allows content transfer from a reservoir to an applicator without peripheral sealing, enabling precise application of liquids, gels, or pastes, and featuring a breakable mechanism for opening and a disposable design for single-use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple opening for distributing content is used, then the device structure is simplified, but the content application precision in terms of size, shape, limit, and quantity is insufficient
Solution Approach 1:
The device is divided into two functional parts: a reservoir for content storage and an applicator for precise application. The applicator includes a distribution member with a tip that can be inserted into the reservoir, separating the storage function from the application function to achieve both simplicity and precision
Solution Approach 2:
A distribution member acting as an intermediary transfers content from the reservoir to the application surface. This intermediary component (rod with tip) enables precise content delivery while maintaining a simple overall device structure without complex dispensing mechanisms
2Manufacturing precision
If a complex device with multiple assemblies and flanges is used, then content distribution and application precision is improved, but the device becomes too complex for simple single-use applications
Solution Approach 1:
The invention extracts only the essential components needed for precise content application: a reservoir and a simple applicator with a distribution member. Complex elements such as multiple flanges, gutters, and expansion collars are removed, retaining only the breakable seal and tip structure necessary for controlled content delivery
Solution Approach 2:
The device is designed as a disposable single-use unit with a breakable seal that is destroyed upon first use. The reservoir and applicator are integrated into a non-resealable package that is discarded after content depletion, eliminating the need for complex reusable mechanisms while ensuring precise content application
3Device complexity
If a non-resealable packaging with deformable wall is used, then the device is simplified for single use, but it lacks a real means for distributing and applying content precisely
Solution Approach 1:
The applicator is pre-assembled with the reservoir in a sterile, ready-to-use configuration before sealing. The distribution member is positioned within the reservoir during manufacturing, so that upon breaking the seal, the content application mechanism is immediately functional without requiring assembly steps
Solution Approach 2:
The breakable seal automatically opens upon application of modest force to the deformable wall, allowing the distribution member to access the content. The device self-activates the content delivery mechanism through simple user pressure, eliminating the need for complex opening mechanisms while enabling precise content application

AI summary
The invention relates to a device (1) for containing, dispensing and applying to a substrate content in liquid, gel, cream or paste form, said device including a shaped semi-rigid wall (5), a closing wall (6) and an applicator (7) having an attachment portion (8) and an application portion (9) as an extension of one another. The device is characterised in that the shaped semi-rigid wall (5) comprises a portion (11) for receiving content, an attachment portion (12) with an inner projection and a protection portion engaging with the attachment portion and the application portion of the applicator; the closing wall (6) covers the semi-rigid wall; a breakable means (3) is placed between the attachment portion and the protection portion; a content-transfer passage (16) communicates with the content vessel and the application portion of the applicator, and is made with a structure having a radial spacing that ensures no peripheral tightness between the outer peripheral surface (17) of the attachment portion (8) of the applicator and the inner peripheral surface (18) opposite the attachment portion (12) of the shaped semi-rigid wall (5), the structure having the radial spacing extending in a communicating, continuous fashion along the axis between, on one side, the content vessel (2) and, on the other side, the breakable means (3) and the application portion (9) of the applicator (7); and in that the content to be applied from the application portion (9) of the applicator (7) is supplied from the outer peripheral shell (9a) thereof, while the content is capable of passing through the transfer passage (16) and of being applied as though with a brush.
