Description
Technical field
The present invention relates to annular groove plastic bottle idiosome injection mold, particularly relate to PET material make plastic bottle outside have
Deep annular groove, plastic bottle oral area have externally threaded injection mold and using method thereof.
Background technology
PET bottle is the beverage packaging that current usage amount is maximum, is widely used in food, chemical industry, drug packaging etc. numerous
Field.PET bottle surface is smooth and glossy.Resistance to creep, fatigue resistance, rub resistance and good stability of the dimension, wear away little and
Hardness is high, has toughness maximum in thermoplastic；Electrical insulation capability is good, and temperature influence is little, but corona resistance is poor.Nothing
Poison, against weather, chemical proof good stability, water absorption rate is low, weak acid resistant and organic solvent.
Traditional pickle jar uses glass, ceramic material to make, and is provided with tank, the altar lid base above altar mouth outside altar mouth
Stretch into bottom of gullet, add appropriate water in the sink and just can seal altar mouth.Due to glass and pottery fragility, often because of
Damage for imprudence collision, use very inconvenient.Annular groove plastic bottle is traditional glass, the succedaneum of pottery pickle jar, plastics
