Abstract

A crystallized bottleneck structure of polyester beer bottle is characterized in that a protruded edge is arranged on the end portion of the bottleneck; a crystallized portion with crystallizing length between 0.5-19 mm is arranged downwardly from the end portion of the bottleneck and includes a non-crystallized layer at the core portion. The crystallized bottleneck structure is composed of a crystallized inner side and outer side, and a non-crystallized core portion; an arc transition region is arranged between the protruded edge and the top surface of the bottleneck. The crystallized bottleneck structure has flexibility and improved compression strength to prevent cracking while capping. Moreover, the bottleneck can be sealed not only by a plastic cap but also by a metal cap, and the sealed bottleneck can bear pressure larger than 175 PSI.

Description

A kind of crystallized mouth structure of polyester beer bottle

Affiliated field

The utility model relates to a kind of container that is used for the splendid attire fluent, relates to crystallized mouth structure of polyester beer bottle particularly.

Background technology

At present the beer bottle that uses mostly is glass bottle, because it is broken easily, even happen occasionally beer bottle nature explosion and the people's that causes injury phenomenon; So beginning to use instead plastic bottle, people take splendid attire beer, reported a kind of " Zero oxygen permeation plastic bottle that is used for beer and other purposes) " as Chinese patent application CN97198781.5, this is the container of the multiple-structure made of a kind of plastics, be used for splendid attire beer, fruit juice, condiment etc., wherein include one deck oxygen scavenger especially.It is complicated especially that the structure of this plastic beer bottle and manufacture craft all seem, need to use the low polymerization degree polyester of special formulation to produce, so that its manufacturing cost is higher, is difficult to large-scale production and puts on market.

Consider that from another point of view existing plastic beer bottle is because on its bottleneck and the bottom structure, for example whole crystallizations of bottleneck portion, bottleneck can not be high temperature resistant, deforms easily when bottleneck is heated and cause the bottleneck poor sealing; Bottle end diameter is identical with the body diameter, the bottle end, do not have the distressed structure of doing, make the integrated support hardness at the bottle end be not so good as glass bottle, therefore deform easily in actual use, especially when beer carries out high temperature sterilization, bottle almost can't keep original shape, even bottleneck distortion, the bottle end take place outwards protrudes and the phenomenon of astasia, and this directly has influence on applying it.

The utility model content

The purpose of this utility model provides a kind of follow-on crystallized mouth structure of polyester beer bottle, makes it improve sealing property greatly, improves to hold quality of beer.

The utility model is achieved in that the bottleneck port is provided with a protruding rim, it is downward to control the bottleneck top, be provided with the crystalline portion of crystallization length between 0.5-19mm, the core of described crystalline portion contains not crystallizing layer, and the bottleneck structure after the crystallization is made of inside portion, outside portion and the uncrystallized core of crystallization; Use the arc transition between described protruding rim and the bottleneck top end plane.

Core is non-crystallizable by making bottleneck form the complete crystallization of inside and outside sidepiece when the crystallization for the utility model, makes bottleneck have certain elasticity, improves bottleneck compressive strength, makes the bottleneck can embrittlement in the gland use; With the transition of multistage arc, make bottleneck except being applied to and also can be applied to the gland packing of crown cap plastic bottle closure seals between projection rim and the bottleneck top end plane, make bottleneck after the sealing can bear pressure greater than 175PSI.

Fig. 2 is Figure 1A-A cut-away view;

Specific implementation

As shown in Figure 1 and Figure 2, the utility model is achieved in that the bottleneck port is provided with a protruding rim, it is downward to control the bottleneck top, be provided with the crystalline portion of crystallization length between 0.5-19mm, the core of described crystalline portion contains not crystallizing layer, and the bottleneck structure after the crystallization is made of inside portion 1, outside portion 2 and the uncrystallized core 3 of crystallization; Cross with the arc limit between described protruding rim and the bottleneck top end plane.It is connected to each other by 5 sections circular arcs and forms (as Fig. 9).In the scope of arc radius R1 between 2-3mm; In the scope of arc radius R2 between 3-5mm; In the scope of arc radius R3 between 4-6mm; In the scope of arc radius R4 between 0.1-0.9mm; In the scope of arc radius R5 between 1.5-3mm.
