Analysis the advantages and disadvantages of two kinds of hose cosmetics lid, plastic bottle cap - Card covered by jaw or card buckle and so on the lid of the structure are connected to the container, usually referred to as card buckle cover. Card buckle cover design is based on the high toughness of plastic itself, PP/PE this toughness good material, in particular, can give full play to the advantages of the claw structure. During the installation process, when the pressure to pull on the bottle of ratchet structure, card buckle jaw short deformation happens. Then, under the action of the elastic material, rapid restorable, jaw hold container port. Therefore, the lid can be fixed on the container. This efficient connection method is particularly popular in the industrial mass production. Characteristics: plastic covered the advantages and disadvantages of the analysis through the press will cover is fixed on the container port. Advantages: easy installation, low manufacturing cost. Disadvantages: uneven axial force, will pull out under a certain force. Purpose: in the low cost of fast-moving consumer goods packaging requirements are a good choice. Second, the plastic cover - Welding cover by hot melt welding wire and other structure directly welded to the lid on flexible packaging called welding cover. It is actually a spiral cover and clamp cover derivatives, it only separation in the export and assemble them into the container. After weld cap is plastic flexible packaging of a new type of bottle caps. Widely used in cosmetic, medicine, food and other industries. Analysis on the advantages and disadvantages of plastic welding cover features: weld cap opening part adopts hot melt welding on the flexible packaging way. Advantages: low cost, environmental protection. Faults: consumers' experience in the process of use is not very good. Use occasions: on some additional products such as promotional products are widely used.
