New product design contest on Desall and a multinational leader in the packaging industry invite you to design a new squeeze nebulization system for liquids specifically designed for disposable bottles.

Company description

This competition is sponsored by a prominent multinational company specializing in dispensing technologies in the packaging industry.

The brief is available in the following languages:
- English
- Italian

What we are looking for

Our goal is to find a new mechanical dispensing system that can nebulize liquids into the air through the compression (squeezing) of a dedicated area, a specific component, or the entire disposable bottle. The proposed solution must offer an innovative mechanism or type of interaction that sets it apart from the current market offerings, with a focus on environmental sustainability and minimizing the number of components needed for operation.


To ensure the proper development of your projects, please consider the following guidelines:

Product typology

Nebulization is the process of reducing a liquid into very small droplets, which can be achieved by passing it at high speed through narrow channels with particular geometries or by subjecting it to an air jet.

We invite you to design a mechanical nebulizer that operates differently from aerosol nebulizers. Unlike aerosol nebulizers that rely on the pressure of gas inside the bottle, the proposed mechanical nebulizer must push and nebulize the liquid through the mechanical compression of the dispenser.

The user interaction should involve squeezing a specific deformable part of the dispenser (e.g., the entire bottle, a dedicated area, or a specific component), to push the liquid out. Please note that solutions involving spray pumps activated by pressing a button will not be considered.

Please refer to the Inspiration section of the contest for examples of similar products and patents.

There are no constraints on the configuration of the elements with which the user will interact to nebulize the liquid, but it should be practical to dispense with one hand.
You may include the bottle containing the liquid in the project if it is a functional part of the dispensing system; otherwise, its design is optional.

The system will mainly be used in an upright position, with the nebulizer spray directed upwards. Ideally, the dispensing system should allow for nebulization of the liquid even when upside down, although the ideal condition is for the system to operate in all directions, 360°.

The system must be leak-proof, preventing accidental spillage when turned upside down or exposed to vacuum.

Overall technical feasibility is a critical consideration for the nebulizer’s design.

Usage mode
Consider the product’s usage mode when designing the dispensing mechanism. Explore alternative interaction modes and nebulization systems to current dispensing methods. Activate the dispenser by compressing (squeezing) a specific deformable part (the entire bottle, a dedicated area, or a specific component) that pushes the liquid out of the bottle. Avoid solutions that involve spray pumps activated by a button press.

Check out the Inspiration section of the contest for examples of similar products and patents.

You are invited to propose solutions that minimize the number of components in the dispensing mechanism and provide easy disassembly. Currently, traditional nebulization systems have nine parts, and some recently designed ones have four parts. The number of required parts should be around four or lower. Ideally, the parts should be designed with reduced material usage.

Materials and production technologies
Preferably, recyclable thermoplastic materials such as PE and PP should be used. The use of PET is allowed, but it is not the ideal solution as it has a lower recyclability percentage.
You are free to propose the use of other types of recyclable plastics, provided that they are compatible with mass production technologies, particularly injection moulding.
The use of other materials such as metals or non-recyclable plastics is not allowed.
The entire dispensing system and its individual components should preferably be made of a single material. Co-moulding is allowed if it does not compromise the recyclability of the product.

The parts will be produced through injection moulding or extrusion.

The product’s style or aesthetics are not the focus of this contest. Solutions that prioritize aesthetics over functionality will not be considered.
The solution sought is for the cosmetics, food, and hygiene sectors.

The product should be ergonomically designed for one-handed use, and the attached bottle should not exceed a capacity of 0.5 litres. No specific size constraints apply beyond these requirements.

Target audience
The dispenser design is targeted towards B2B customers operating in the cosmetics, food, and hygiene sectors. They will purchase the dispenser to market their products in the mass market.

Production cost
Your proposed dispenser should have the lowest possible production cost and be suitable for sale in the mass market. This can be achieved by reducing the number of components required for operation and adopting cost-reducing solutions in the design.

Required materials
Provide detailed descriptions and a series of images to present your projects effectively. The images visible in the gallery (up to 5) should have a 4:3 proportion, with accepted file formats being .jpg, .gif, or .png. The colour mode should be RGB, and the maximum size of a single file should be 1MB. For a better understanding of the project, you are encouraged to present at least one section and an exploded view of the mechanism, accompanied by a detailed description of the dispensing system’s operation. You are also invited to upload a .zip archive containing 3D files and high-resolution images of the proposals during the project upload phase. The maximum size for the .zip file is 100MB.

Judging criteria
The entries will be evaluated based on the following criteria:

Technical feasibility 5/5
Economic sustainability 5/5
Eco-friendliness 5/5
Degree of innovation 4/5
Functionality and usability 4/5

English – Desall is an international community, so all texts (abstract, description, tags, etc.) must be written in English.

Contest Timeline

Upload phase: 9 March 2023 – 11 July 2023 (1.59 PM UTC)
Concept review: 8 June 2023 (1.59 PM UTC)
Client vote: from 11 July 2023
Winner announcement: tentatively by the end of September 2023

Concept review (optional)
Participants have the opportunity to request an optional review of their project by the Desall team by the date indicated above. To do so, they must 1) save their project as a draft from the upload page and 2) send a request to the Desall team via email at or through the contact form. The review is not mandatory and only provides an opportunity for participants to receive feedback but does not constitute a necessary condition for participation or provide any advantage in the final evaluation by the Sponsor.

Participation criteria
Participation is free and open to creative talents of any nationality aged 18 or older. Participants may submit one or more projects, but only projects published on the website from the upload page dedicated to the contest will be accepted.

1°: €5000
The selection of winners will be the result of an indisputable evaluation by the Sponsor. Originality, feasibility, and coherence with the brief will be taken into consideration.

Extra Award (option right fee)
Throughout the duration of the option right, the Sponsor offers an additional opportunity to all participants by setting the compensation of €2500 for the purchase of the license for the economic exploitation of projects not recognized as winning proposals. For more information, log in and read the Contest Agreement from the upload page. For questions about the brief, use the “Have a question” button or write to


Since we are an international Community, all texts provided with your uploads (abstract, description, tags, etc.) should be written in English.
