The Plastic Lotion Pump Bottle should be well controlled and designed in the production, produced according to a certain production and processing technology, and has good performance and functions, which can fully demonstrate the important value in the industry.
1) When designing the extruded plastic emulsion pump bottle, if the material is high-density polyethylene or polypropylene, the cross-section of the plastic bottle should be rectangular or oval. For low-density polyethylene or other flexible plastic bottles, the cross-section is preferably circular. This facilitates squeezing the contents from the plastic bottle. The plastic parts used in conjunction with the plastic bottle mouth are mainly caps and sealants. The design of the plastic bottle mouth should focus on considering how to make the plastic bottle mouth better fit the plastic bottle with lid and sealant, which is the weak part of the mechanical performance of the plastic bottle. Therefore, the bottom of the plastic lotion pump bottle is usually designed to be concave. The corners of the plastic bottle and the recessed part are excessively bent. In order to facilitate the stacking of plastic bottles, the stacking stability of the plastic bottles is improved, and the bottom of the plastic bottles should be designed with internal grooves.
2) When marking the surface of the plastic lotion pump bottle, the surface of the label should be flat. A "frame" can be designed on the surface of the plastic bottle so that the label can be positioned accurately without moving. During blow molding, the part of the parison that expands the first contact always tends to be hardened first. Therefore, the wall thickness of this part is also larger. The edges and corners are the parts where the parison makes the last contact and expand, and the wall thickness of this part is small. Therefore, the edges and corners of the plastic bottle should be designed to be round.
