What is the main function of foam bottle
source：m.fengrong.net | Release time：2025-09-02
The core function of foam bottle (also known as foam generator, foam spray bottle) is to mix liquid (such as detergent, nursing liquid, medicament, etc.) with air in proportion to generate delicate and stable foam. By optimizing the liquid form, the efficiency, effect or safety of use can be improved. It is widely used in many fields such as cleaning, personal care, medical care, industry, etc. Its function can be developed around two dimensions: "functional optimization" and "scene adaptation", as follows:
1、 Core function: Optimize liquid form and enhance usage value
The essence of foam bottle is to change the existing form of liquid through physical structure (such as built-in press pump, mixing chamber, screen, etc.) to solve the problem of "low efficiency, large waste and poor effect when liquid is used directly". The core role is reflected in three aspects:
1. Reduce liquid usage and minimize waste
The liquid in the foam state has a "larger coverage area" than the pure liquid - under the same volume, the surface volume of the foam is far larger than the liquid, which can be evenly attached to the target surface (such as tableware, skin, clothing) without repeated application or dumping.
For example, when foam bottles are used to separately pack detergent, one pump of foam can cover 3-4 dinner plates, while it takes 2-3 times the amount of liquid directly to achieve the same coverage effect. Long term use can reduce the liquid consumption by 30% -50%.
2. Improve cleaning/functional efficiency and reduce residue
Delicate foam can "penetrate the gap" and "extend the contact time":
Cleaning scenes (such as kitchen oil stain and bathroom scale): foam can be attached to vertical surfaces (such as walls and side walls of pots and pans), and will not flow as fast as liquid, so there is more time to decompose oil stain and dirt, and cleaning is better;
Care scenes (such as face cleaning and shaving): foam can wrap the dust and oil on the skin surface, while buffering friction (such as the contact between the razor and the skin), avoiding scratches, and foam is easy to be washed away when washing, reducing the damage to the skin caused by liquid residues.
3. Control liquid concentration and adapt to specific needs
Some foam bottles (such as press bottles with dilution function) can realize "automatic dilution" of liquid by mixing "liquid+air+water". For example, in the industrial scene, pour the high concentration disinfectant into a foam bottle, and automatically mix air and water when pressing to generate a low concentration foam, which not only avoids the risk of direct contact with the high concentration liquid, but also correctly controls the disinfection concentration to prevent excessive disinfection from damaging the surface of objects (such as metal, cloth).
2、 Scenario based function: Adapt to the special needs of different fields
The design of foam bottles will be adjusted according to the use scenarios (such as foam fineness, anti-corrosion materials, and pressure), and their functions will also be refined according to the scenarios. Common areas include:
1. Daily cleaning field (household, commercial)
Kitchen/bathroom cleaning: with detergent, scale remover and glass cleaner, foam has strong adhesion, and there is no need to spray repeatedly when cleaning vertical surfaces (such as range hoods and ceramic tile walls), so as to reduce liquid dripping and polluting the floor;
Local cleaning of clothes: put collar cleaner and stain remover, and foam can correctly cover the stain area (such as collar and cuff) to prevent liquid diffusion from polluting other fabrics, and it is easy to wash without residue;
Cleaning of public scenes: foam bottles of hand sanitizer in shopping malls and hotels can avoid direct contact with liquids (reduce cross infection), and the amount of foam can be controlled to reduce the cleaning cost of public areas.
2. Personal care field
Cleansing/Makeup removing: After the cleansing products (such as amino acid cleansing and soap based cleansing) are made into foam, the texture is more mild, reducing the friction of pure liquid on the skin, especially suitable for sensitive muscles; Makeup removing foam can wrap makeup particles, avoid greasy feeling of makeup removing oil/water, and it is more convenient to wash;
Shaving care: shaving foam (or foam bottle sub packaging shaving cream) can soften the beard, lubricate the skin, cushion the friction of the razor, reduce scratches, redness, and is more uniform than directly applying shaving cream;
Oral care: Some mouthwash foam bottles (such as children's mouthwash) convert liquid into foam to avoid children swallowing liquid directly. At the same time, foam can more fully contact the oral mucosa to improve the mouthwash effect.
3. Medical and health field
Skin administration/disinfection;
Oral/nasal care: foam for oral ulcer care and foam for nasal irrigation. The foam is mild in shape and will not hurt mucous membrane like liquid. It is suitable for children, the elderly and other sensitive people.
4. Industrial/Special Fields
Food processing cleaning: foam cleaning agent (such as pipeline cleaner and equipment disinfectant) in the food workshop can form a protective film on the food contact surface (such as conveyor belt, tank inner wall) to ensure that there is no dead corner in cleaning and disinfection, and meet food level safety standards (most materials are PP, PET, acid and alkali resistant);
Agriculture/gardening.
3、 Additional function: Enhance user experience and security
In addition to its core functions, foam bottles can also optimize the use experience through detailed design:
Avoid direct contact and reduce pollution: the pressed foam bottle does not need to open the bottle cap, and the liquid is sealed in the bottle all the time to avoid bacterial pollution caused by hand contact with liquid (such as hand sanitizer bottle in public places and household disinfectant bottle);
Control dosage and prevent misoperation: The quantitative pressing design (such as a fixed output pump) can prevent children or the elderly from losing control of the dosage when pouring liquids (such as accidentally pouring a large amount of detergent or disinfectant), reducing safety risks;
Portable and storage: small foam bottles (such as travel clothes) are small in size and have strong sealing property. They can be separately packed with shampoo and shower gel to prevent liquid leakage from polluting luggage, and meet the requirements of aviation security inspection for liquid carrying (liquid in foam bottles is not easy to overflow, and some can be carried with you).
