PET tanks

Technical field

The utility model is related to a kind of jar, more particularly to a kind of PET tanks for being used to place foodstuff article.

Background technology

PET plastic is the abbreviation of English Polyethylene terephthalate, abbreviation PET or PETP.PET plastic point Minor structure high degree of symmetry has certain crystalline orientation ability, so with higher film forming and become second nature.PET plastic has Good optical property and weatherability, amorphous PET plastic have good optical transparence.In addition PET plastic has excellent Good abrasion performance frictional property and dimensional stability and electrical insulating property.The bottle that PET makes is big, transparent good, nontoxic, anti-with intensity Infiltration, light weight, production efficiency height etc. are thus received and are widely applied.PET is milky or light yellow highly crystalline Polymer, smooth surface and it is glossy.Creep resistance, fatigue resistance, rub resistance are good, and abrasion are small and hardness is high, have thermoplasticity Maximum toughness in plastics；Electrical insulation capability is good, is affected by temperature small, but corona resistance is poor.Nontoxic, against weather, anti-ization It is good to learn stability of drug products, hygroscopicity is high, and the drying before molding is necessary.Weak acid resistant and organic solvent, but intolerant to hot-water soak, It is not alkaline-resisting.

The glass transition temperature of PET resin is higher, and crystallization rate is slow, and moulding cyclc is long, and molding cycle is long, molding shrinkage Greatly, poor dimensional stability, the molding of crystallization is in brittleness, and heat resistance is low etc..

The PET tanks of the prior art are blow moldings, and neck must be set near tank mouth, so as to blow molding and into Pickup after type, but be blow molded and need previously prepared bottle base, then carry out blow molding, the entire production cycle is longer, production efficiency compared with It is low, and equipment cost is also higher, thus there are manufacturing cost it is higher the problem of.

Utility model content

The utility model provides the PET tanks that a kind of production cycle is shorter and manufacturing cost is relatively low in view of the above problems.

The utility model solve problem above used in technical solution be：A kind of PET tanks having following structure are provided, it Including tank body, the tank body is followed successively by flange, can body and tank bottom from top to bottom, and the thickness of the flange is 0.4~1.6mm, institute The outer diameter for stating flange is equal to the sum that can body outer diameter adds 2~5mm；The can body outer diameter is 80~85mm, the can body and tank The wall thickness at bottom is 1~2.8mm；The middle part of the tank bottom is equipped with the indent of arc, and the depth of the indent is 2~6mm；The tank The inner wall of the nearly flange one end of body is equipped with the first inclined-plane, and it is corresponding that the corresponding wall thickness in the first inclined-plane upper end is less than the first inclined-plane lower end Wall thickness, and the upper end on the first inclined-plane is concordant with the upper surface of flange.

Preferably, the weight of the tank body is 40~65g.

Preferably, the height of the tank body is 60~110mm.

Preferably, the lower section on the first inclined-plane is equipped with the second inclined-plane and the successively on the inner wall of described nearly flange one end of can body Three inclined-planes, by the second chamfered transition between first inclined-plane and third inclined-plane, and the inclination side on the second inclined-plane and third inclined-plane To identical with the first inclined-plane；Angle between first inclined-plane and vertical line is more than the angle between third inclined-plane and vertical line, and Angle between second inclined-plane and vertical line is less than the angle between third inclined-plane and vertical line；Then in this way setting after, not only be convenient for into Type and demoulding also help saving raw material, and ensure the intensity of tank mouth.

Preferably, the vertical height on first inclined-plane is 1~3mm.

Preferably, the vertical height on second inclined-plane is 3~5mm, the vertical height on the third inclined-plane for 2~ 4mm。

Preferably, the middle part on second inclined-plane is equipped with convex ribs；Then after convex ribs setting, the intensity of tank mouth can be enhanced, and And also it can provide button bit for corking.

Preferably, the diameter of the tank bottom is less than the diameter of can body；Then in this way setting be more convenient for the utility model into Type and demoulding.

Preferably, a diameter of 56~60mm of the indent in tank bottom bottom opening, and the center of indent is in can body On axis.

After more than structure, compared with prior art, after the utility model due to setting in this way, ensureing using effect Under the premise of, can direct injection molding, eliminate blow-molding process, production efficiency can be greatly improved, also save blow moulding equipment Cost, and then the production cost of the utility model can be greatly reduced；And also no longer need to set neck, structure is simpler, makes Obtain the whole more coordination of the utility model and beauty.Therefore the utility model have that the production cycle is shorter and manufacturing cost relatively The characteristics of low.
