1. Material: The material requirements of the glass bottle are the same as the standard sample.

2. Dimensions: The outer diameter of the bottle body, the inner and outer diameters of the bottle mouth, the bottle height, the outer diameter of the thread, and the thickness of the bayonet, etc. are measured with a vernier caliper and height ruler with a minimum scale value of 0.01mm.

3. Air-tightness requirements: Fill the product with water, and lay it down (or upside down) on the absorbent white paper in the vacuum box. Vacuum for 15 minutes, the loss rate must not be large

At 0.5%. Vacuum box air pressure refers to the product material is ordinary material -0.06MPa, the product material contains volatile components: -0.08MPa.

Physical and chemical performance standards

Heavy metal content: the sum of the total content of lead, cadmium, mercury and hexavalent chromium ≤ 200mg / KG, arsenic-free

Internal stress: ≤3

Thermal shock resistance: 42 ° C

Inner surface water resistance: HC3

Impact resistance: 0.6J

Content requirements

Take a certain amount of water and fill it with a measuring cylinder to the shoulder of the bottle. Calculate whether it meets the requirements of the net content. If necessary, use the actual contents for testing. When filling the contents to the shoulder of the container (beautiful filling height), Greater than the marked value of the product is less than 105% of the marked value of the product.

Compatibility requirements

Bottles and caps (nozzles), gaskets, inner plugs (inner bowls) need to cooperate smoothly, and there should be no overtightening, too loose, crooked head, or slippery teeth; the distance between the bottle and the cap (nozzle) is 0.3-0.8mm between.
