Frequent Problems In The Production Of 10ml Pen Sprayer Bottle

(1) When designing extruded 10ml Pen Sprayer Bottle, if the material is high-density polyethylene or polypropylene, the cross-section of the plastic bottle should be rectangular or elliptical. For low-density polyethylene or other flexible plastic bottles, the horizontal The cross section is preferably a circle. This facilitates the extrusion of the contents from the plastic bottle. The plastic parts used in conjunction with the plastic bottle mouth are mainly caps and seals. The design of the plastic bottle mouth should focus on how to make the plastic bottle mouth better fit the lid and sealer. The bottom of the plastic bottle is the weak part of the mechanical properties of the plastic bottle. Therefore, the bottom of the plastic bottle is generally designed to be concave; the corners of the plastic bottle and the concave portion are excessively curved. In order to facilitate the stacking of plastic bottles, the stacking stability of the plastic bottles is increased, and the bottom of the plastic bottles should be designed with inner grooves.

(2) When the surface of the 15ml Alum Perfume Bottle is marked, the surface of the label should be flat. A “sash” can be designed on the surface of the plastic bottle to make the label accurately positioned without moving. At the time of blow molding, the portion where the parison inflates first contacts always tends to be hardened first. Therefore, the wall thickness of this part is also larger. The edge and the corner portion are the portions where the parison inflates the last contact, and the wall thickness of the portion is small. Therefore, the edges and horns of the plastic bottle should be designed to be rounded. Changing the surface shape of the plastic bottle, such as the middle of the plastic bottle is relatively thin, increasing the circumferential groove or rib of the surface of the plastic bottle, which can improve the rigidity and bending resistance of the plastic bottle. Longitudinal grooves or ribs eliminate the offset, sagging or deformation of plastic bottles under long-term load.
