For more than 20 years, MEGAPLAST has gained the trust of many famous cosmetics brands in the world with its rigorous production process and excellent product quality. Well-known brands that have used MEGAPLAST PP vacuum bottle packaging products include: L'OREAL, WELLA, BODY SHOP, Johnson-Johnson, NIVEA and OLAY and many other well-known brands.
The main component of the patented design of the MEGAPLAST PP vacuum bottle lies in it (see the attached drawing)
1. Upper valve
2. Bellows telescopic plastic tube
3. Lower valve
The three parts replace the slingshots, steel balls and other components of the conventional vacuum flask. When the pump head is pressed, the Bellows (the telescopic plastic tube) moves up and down, causing the upper valve and the lower valve to open and close to form a bottle. The gas pressure is lower than the outside of the bottle, so the gas pressure outside the bottle pushes the Piston upward and generates a thrust force to squeeze the emulsion out of the bottle.
Slingshots and steel balls of traditional vacuum flasks are in contact with the emulsion in the bottle and are prone to corrosion of the slingshots and balls due to the emulsion, causing the emulsion to spoil. At the same time, the main parts of the MEGAPLAST bottle are all molded by pp. pp materials are relatively plastic such as as and ps. Material, chemical and physical properties are quite stable, pp material itself has a better gas density, to further avoid the possible problems caused by the bottle material issues such as chemical reactions, toughness is not easy to rupture and so on. Therefore, MEGAPLAST PP Vacuum bottles are particularly suitable for anti-corrosion requirements of the emulsion products.
Another patent for the MEGAPLAST PP vacuum bottle is its A30-07 pump head. This pump head has a valve inside the emulsion outlet. It opens only when the emulsion is extruded. After the emulsion is extruded, the valve will close automatically. The possibility of contact with the air in the bottle is minimized and the "vacuum" effect of the vacuum bottle is fully utilized.
Currently, only MEGAPLAST vacuum flasks in the world completely abandon metal slingshots and steel balls. The entire bottle body is made of plastic: the bottle body is molded from pp, the patented Upper valve, Bellows (retractable plastic tube) and The lower valve is made of EVA injection molded, Piston (piston) and caps are injection moulded with pe. The plastic materials used in the above parts are naturally decomposable, so the MEGAPLAST PP vacuum flask is a real one. Environmentally friendly products.
