Abstract

The utility model relates to a bottle, in particular to a PET bottle which is applied in liquid storage and transportation and especially suitable for containing beverage with normal internal pressure or boost internal pressure. The utility model is characterized in that: the crown part (1) is provided with side wall which and outer diameter of side wall (D2) is approximately 1.08-1.10 times of the diameter (D1) of the internal side wall. The preferential value is 1.09 times. The top of the crown is also provided with flange (3) and the outer diameter (D3) of flange (3) is approximately 1.13-1.15 times of the diameter. The preferential value is 1.14 times. Further more, the height of the flange (3) is about 0.1 time of the diameter (D1) of the internal wall side. On the surface of the external wall side, the outline diameter (D4) of the screw (4) on the crown is about 1.24-1.28 times of the diameter of the internal wall side (D1), with preferential value 1.26 times.

Description

Bottle

Technical field

Theme of the present utility model is a kind of bottle, especially a kind of PET bottle, and this bottle is used for storing and transport liquid, particularly has the beverage of normal air pressure power or enhancing internal pressure.

Background technology

Bottle is the forming containers with shaping bottleneck.The bizet of this bottle has interior conduit, in the outside of this bizet the shaping screw thread is arranged, and generally is the Acme thread with down suction.

In the prior art, the external diameter of this bizet approximates 1.14 times of internal diameter greatly.This shaping bizet has outside thread.

This scheme needs great deal of raw materials---plastics.

Because this diameter is uniformly along whole outer surface, and this lip-deep screw thread has limited height, so it has reduced and the mating surfaces that covers screw thread.

The utility model content

The purpose of this utility model provides a kind of bottle, to reduce raw materials consumption and to improve the leak tightness of bottle cap.The utility model is a kind of for the bottle of forming containers form, bottleneck is arranged at its top, the top of bottleneck has bizet, this bizet has the screw thread that is used for and becomes the female cap cooperation, it is characterized in that: this bizet has wall, the external diameter of this wall approximates 1.08～1.10 times of inner diameter greatly, is preferably 1.09 times; And the top at bizet has flange, and the external diameter of this flange approximates 1.13～1.15 times of inner diameter greatly, is preferably 1.14 times, and the height of this flange approximates 0.1 times of inner diameter greatly; On outer wall surface, the outline diameter of the screw thread of this bizet approximates 1.24～1.28 times of inner diameter greatly, is preferably 1.26 times.

Provide following technological merit and practical advantage according to scheme of the present utility model:

---reduced the raw materials consumption in the bottle manufacturing process,

---reduced manufacturing cost,

---improve the leak tightness of lid;

---improved of the setting of the side surface of lid at the sealing surfaces place,

---reduced the weight of bottle,

---on the screw thread mating surfaces, have better power and distribute to improve the leak tightness of bottle.

Description of drawings

Show theme of the present utility model among Fig. 1, the figure shows the profile of bottle bizet when observing from the side.

The specific embodiment

Cylindrical shape bizet 1 is as the intrinsic part of this bottle and be positioned on the neck (not shown), and this cylindrical shape bizet 1 has the inside face that diameter is D1, and this inside face comprises pipeline 2.The diameter D2 of this bizet outside face approximates 1.09 times of diameter D1 greatly.The height h of flange 3 approximates 0.1 times of diameter D1 greatly; And the outer diameter D 3 of flange approximates 1.13～1.15 times of this inner diameter D1 greatly, is preferably 1.14 times.Bizet on outer wall surface has sectional type screw thread 4, and the outline diameter D4 of this screw thread 4 approximates 1.26 times of this inner diameter D1 greatly.Below this screw thread, this bizet 1 has the PET flange 5 of standard.

Claims

1. one kind is the bottle of forming containers form, bottleneck is arranged at its top, the top of bottleneck has bizet, this bizet has the screw thread that is used for and becomes the female cap cooperation, it is characterized in that: this bizet (1) has wall, the external diameter of this wall (D2) approximates 1.08～1.10 times of inner diameter (D1) greatly, is preferably 1.09 times; And have flange (3) at the top of bizet, the external diameter (D3) of this flange (3) approximates 1.13～1.15 times of inner diameter (D1) greatly, is preferably 1.14 times, and the height of this flange (3) approximates 0.1 times of inner diameter (D1) greatly; On outer wall surface, the outline diameter (D4) of the screw thread of this bizet (4) approximates 1.24～1.28 times of inner diameter (D1) greatly, is preferably 1.26 times.
