🌟 Introduction

Widely used in cosmetics, pharmaceuticals, household cleaning and other fields, it has become a common choice for packaging liquid products due to its excellent sealing and chemical stability.

In order to ensure the safety and functionality of glass spray bottles in use and to enhance the user experience, strict quality inspection becomes an indispensable link. The goal is to avoid leakage, breakage or uneven spraying due to bottle defects.

This paper analyzes the quality inspection of glass spray bottles and discusses its important role in ensuring product performance and safety. It focuses on the inspection methods and applicable standards at different stages of the production and factory processes to ensure that the products comply with industry specifications and meet market demands.

🌟 Glass spray bottle structure and key quality requirements

Main Components

• • Bottles: Glass bottles are responsible for storing liquids and need to have good sealing and chemical resistance to prevent the contents from being outsourced or contaminated.
  • Sprayer: Includes spray head, pump and connecting tube, responsible for atomizing the liquid and spraying it out. The design of the spray head determines the uniformity and flow rate of the spray, while the pump affects the transfer of pressure from the spray head.

Quality Requirements

• • Appearance Quality: the surface of the bottle should be free of obvious defects, such as bubbles, cracks, impurities, etc.; the color is uniform, high transparency, to ensure the appearance of the aesthetic and to obtain consumer recognition.
  • Dimensional accuracy: the dimensions of the bottle body must comply with the design standards, especially the diameter and thread size of the bottle mouth to ensure a close fit with the sprayer and avoid poor sealing.
  • Mechanical properties: the bottle body needs to have impact and pressure resistance to ensure that the glass bottle body will not be ruptured due to excessive external force during the whole process of transportation and use.
  • Functionality: the spray uniformity of the sprayer and the stability of the spray volume must meet the design requirements to ensure that the amount of liquid sprayed each time the use of the same amount of spray, spray effect is good.
