What is the main purpose of glass foam pump bottle
The working principle and structural advantages of glass foam pump bottle
Glass Foam Pump Bottle consists of two parts: bottle body and foam pump head. The glass bottle body is heavy, environmentally friendly and recyclable, suitable for the needs of the mid-to-high-end market. The foam pump head mixes the liquid in the bottle with air through the mixing system in the pump core, and releases fine and uniform foam through the nozzle. This structure can achieve the convenient experience of "no friction foaming", and has obvious advantages in use comfort and hygiene control.
Shaoxing Roman Plastic Co., Ltd. always adheres to high standards in foam pump structural design and material selection. The company has more than 50 injection molding equipment and 15 assembly and packaging lines, and has integrated service capabilities from structural development, process design to mass production, ensuring that each foam pump bottle can meet the strict requirements of the international market in terms of function and appearance.
Analysis of main application areas
1. Skin care and cleansing products
One of the most widely used areas of glass foam pump bottles is skin care products such as cleansing foam, amino acid cleanser, and makeup remover foam. By lightly pressing the pump head, users can obtain rich and dense foam, which reduces the pulling of the skin and is especially suitable for sensitive skin and high-end skin care brands.
For example, some international skin care brands choose to use silk screen printing or UV spraying on the surface of glass bottles to enhance the visual impact, and at the same time use highly sealed foam pumps to extend the shelf life of the contents. Shaoxing Roman Plastic Co., Ltd. provides full-process OEM/ODM services from bottle design, material selection, customized decoration to functional pump head assembly to help customers create brand-exclusive product lines.
2. Hand cleaning and wash-free products
Since the epidemic, the demand for hand cleaning products has increased significantly, and foam hand sanitizers and wash-free foam disinfectants have become regular daily necessities. Foam pump bottles have significant advantages in this field, such as "controllable dosage, avoiding residues, and not polluting the environment", and are very popular among hotels, offices and home users.
The foam pump bottles produced by Shaoxing Roman support large-capacity (300ml-500ml) and portable specifications. Through a reliable sealing structure, they effectively prevent the volatilization of alcohol components and meet the durability requirements in high-frequency use scenarios.
3. Baby care products
Infants and young children have delicate skin, so skin care and cleaning products must be mild and non-irritating. The fine foam output by the glass foam pump bottle can be directly used for baby shampooing, bathing, hand washing, etc., avoiding irritation caused by direct contact with concentrated liquids.
Shaoxing Roman has developed a low-elasticity, easy-to-operate pump head design specifically for baby products, ensuring that even parents can easily release foam with one hand, while using food-grade raw materials to ensure product safety.
4. Men's care and aftershave products
For men's shaving foam, aftershave cleansing foam, oil control cleansing and other products, the glass foam pump bottle is also an ideal choice for both function and brand image. Shaving foam needs to be dense and highly adherent, and the pump head design needs to have stronger gas mixing ability.
Shaoxing Roman has rich experience in controlling the ratio of foaming pressure and pump core flow, and can provide precisely matched nozzle solutions for different products to ensure that men's products remain efficient and comfortable during use.
5. Pet cleaning products
Pet-specific foam cleaning products have grown rapidly in recent years, such as pet-specific hair washing foam and dry cleaning foam. This type of product requires a sturdy bottle body that is resistant to falling and a safe and easy-to-operate spray head. The thick-walled structure and stable base of the glass foam pump bottle just meet the high standards of the pet products industry for packaging.
Shaoxing Roman provides a variety of capacity and pump types, and supports small-batch customization to help pet care brands quickly respond to market changes and increase product added value.
How is the foam release effect of glass foam pump bottle
The technical mechanism of foam release
The core function of the foam pump is to convert liquid into delicate and stable foam. Its main structure includes:
Liquid storage bottle (i.e. glass bottle part)
Liquid outlet pump core and spring assembly
Foaming chamber and gas mixing membrane
Pressing head and outlet nozzle
Through the pressing action, the pump core sucks the liquid and air in the bottle into the foaming chamber at a set ratio (usually 1:5 to 1:10), and after mixing, it is sheared and compressed through the filter structure to form foam output. Therefore, the quality of the foaming effect depends on the accuracy and sealing of the pump head structure, the rebound speed, the foaming aperture design, and the liquid output of the pump core.
Advantages of glass foam pump bottles
1. Fine and uniform foam, improving skin feel
High-quality glass foam pump bottles can stably output fine foam with a bubble diameter of less than 0.5mm, which is soft and dense, easy to expand on the skin surface, and has excellent feel. It is especially suitable for baby washing, sensitive skin cleansing and other fields that require extremely high foam softness.
2. Precise quantitative control of use costs
Shaoxing Roman Plastic Co., Ltd. uses advanced injection molding technology and automated assembly equipment to ensure that the liquid output of each pump head is controlled within the error range of **±5%** to achieve precise quantitative control. The quantitative release function helps consumers control the dosage and avoid waste, and also helps brands stabilize the formula usage cycle.
3. Efficient gas mixing structure, fast foaming
Traditional plastic bottles have a certain lag between air intake and liquid discharge, while the structurally optimized glass foam pump head can complete the gas mixing and foaming process within 0.2 seconds, improving the smoothness of pressing and the speed of foam generation.
4. The pump head resets quickly and is suitable for high-frequency use.
The pump core spring is made of stainless steel and has been treated with rust prevention. It can achieve a lifespan of up to 20,000 presses and is suitable for high-frequency use in commercial scenarios, such as hotels, public restrooms, chain beauty stores, etc.
What are the transportation and storage conditions of glass foam pump bottles?
Key factors to consider during transportation
Since glass is more fragile than plastic, it must be fully protected throughout the transportation chain. Here are a few key requirements:
Buffering packaging and shock-resistant design
Foam pump bottles should be packed with high-density foam, honeycomb cardboard or corrugated interlayers to effectively reduce vibration and impact during transportation. For high-end customized bottle shapes, customized mold trays or grid partitions should be used to keep the bottle body from shifting.
Separate packaging and pump head protection
To prevent the pump head from failing due to pressure extrusion or external force collision, it is recommended that the pump head and glass bottle body be packaged separately, or a protective cover be installed. In addition, a fixing device should be set at the pump head spring part to prevent elastic fatigue.
Labels, anti-scratch protection
If the bottle surface is UV sprayed, silk-screened or electroplated, an OPP protective film should be applied to avoid damage to the appearance due to scratches, especially in multi-batch stacking transportation.
Environmental control and logistics selection
It is recommended to use constant temperature transportation to avoid expansion or contraction of the bottle due to extreme temperature. For long-distance or export transportation, air transportation or container shipping can be given priority, and warnings such as "fragile", "handle with care" and "do not invert" should be clearly marked.
Professional specifications for storage conditions
In the warehousing stage, the storage conditions of glass foam pump bottles must be strictly controlled to ensure that the product remains in good condition before filling.
Temperature and humidity control
The storage environment temperature is recommended to be controlled at 5℃～35℃, and the relative humidity is between 40%～65% to avoid condensation on the bottle or oxidation of pump head parts due to moisture.
Stacking method and weight limit standard
It is recommended to not exceed three layers of stacking, and a flat interlayer is required between each layer, and the stack height and single stack weight are controlled to prevent the bottom layer of bottles from being compressed and damaged.
Light-proof and dust-proof management
Glass bottles with spraying or color printing should be stored in a light-proof and dust-proof environment to prevent discoloration or ink shedding caused by ultraviolet radiation.
First-in-first-out principle
In order to ensure that the packaging materials do not have surface aging or pump head elasticity decline before use, a strict FIFO (First In First Out) management system should be established.
Routine inspection and maintenance
Regularly check whether the bottles in stock have surface cracks, abnormal pump head elasticity or reduced sealing performance, and keep records to ensure stable and consistent quality out of the warehouse.
