The utility model has the advantages of the bright bottle type of blowing shoulder height.
Description
Technical field
The utility model relates to a kind of bottle base, particularly relates to the bottle base being applicable to blow high bright bottle-type.
Background technology
In beverage industry, the particularly beverage of dairy-type, traditional manner of packing is all adopt glass bottle or polyethylene (PE) bottle to pack, but along with the continuous reduction of International Crude Oil in recent years, polyethylene terephthalate (PET) resin processed by polycondensation from petroleum cracking derivant is then benefited a lot of, price is also continue to drop, in addition the packing cost of glass bottle but significantly rises, so under the pressure of cost pressure, in beverage industry, the bottle-type using PET resin to produce as Raw material processing is sought in more production commercial city, be used for alternative original glass bottle.And require that product design is packed and too large change does not occur glass bottle simultaneously.
Be limited to the difference between PET resin material self character and glass bottle, bottle base traditional so just cannot meet the blowing requirement of similar Glass Bottle, particularly requires that the PET resin bottle of blowing out as the bright imitated glass bottle profile of height cannot realize especially.
Summary of the invention
Technical problem to be solved in the utility model is just to provide a kind ofly can blow the bottle base being applicable to high bright bottle-type, to overcome the deficiency of existing bottle base.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind ofly be applicable to the bottle base of blowing high bright bottle-type, be made up of the base body between at the bottom of bottleneck, base and at the bottom of bottleneck and base, it is characterized in that: described base body is by the linear portion be positioned at below bottleneck, trapezoidal cylinder transition phase, and cylinder-shaped body section three part composition; The length of described linear portion is 4 millimeters-5 millimeters, and monolateral thickness is 2.1 millimeters-2.2 millimeters; The length of described trapezoidal cylinder transition phase is 12 millimeters-14 millimeters, and outer bevel angle is 21 degree of-22 degree, and interior bevel angle is 26 degree of-27 degree; Described cylinder-shaped body segment length is 26 millimeters-27 millimeters, and thickness is 3.4 millimeters-3.8 millimeters.
In further improvement of the utility model, the gradient of described cylinder-shaped body section is 0 degree 15 points-0 and spends 18 points, and the external diameter of described cylinder-shaped body section is 23 millimeters-24 millimeters.
Described linear portion and described trapezoidal cylinder transition phase adopt the circular sliding slopes of R10-R15.
Described trapezoidal cylinder transition phase and described cylinder-shaped body section adopt the circular sliding slopes of R25-R30.
Adopt said structure, because bottle base base body is made up of three parts, particularly interlude is designed to trapezoidal cylindrical transition section, when when heating bottle blowing, under the effect of trapezoidal cylinder transition phase, connect base body two ends, make base body can realize stretching very smoothly, in the process stretched at whole bottle blowing like this, just avoid and form stretching turning, and then avoid appearing at the apparent defect that bottle-type produces impression or became uneven in appearance, finally can realize the PET resin bottle-type of blowing the high bright similar glass bottle of outward appearance, solve technical barrier.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Fig. 1 is the cross-sectional view of prior art bottle base;
Fig. 2 is the cross-sectional view of the utility model bottle base;
Detailed description of the invention
As shown in Figure 2, bottle base of the present utility model, from top to bottom successively by 6 forming at the bottom of bottleneck 4, base body 5 and base.
Wherein, on base body 5, by the linear portion 51 be positioned at below bottleneck, trapezoidal cylinder transition phase 52, and cylinder-shaped body section 53 3 part composition.The length of bottleneck lower straight section 51 is 4 millimeters-5 millimeters, and monolateral thickness is 2.1 millimeters-2.2 millimeters; The outer bevel angle of trapezoidal cylinder transition phase 52 is 21 degree of-22 degree; Interior bevel angle is 26 degree of-27 degree, and trapezoidal cylinder transition phase 52 length is 12 millimeters-14 millimeters; Cylinder-shaped body section 53 length is 26 millimeters-27 millimeters, and thickness is 3.4 millimeters-3.8 millimeters.
Simultaneously the gradient of base body cylinder-shaped body section 53 is 0 degree 15 points-0 degree 18 points, and the external diameter of cylinder-shaped body section 53 is 23 millimeters-24 millimeters; Base body bottleneck lower straight section 51 and trapezoidal cylinder transition phase 52 adopt the circular sliding slopes of R10-R15; The trapezoidal cylinder transition phase 52 of base body and cylinder-shaped body section 53 adopt the circular sliding slopes of R25-R30.
Adopt above-mentioned Fig. 2 structure design, bottle base base body is made up of three parts, particularly interlude is designed to trapezoidal cylindrical transition section 52, when when heating bottle blowing, under the effect of trapezoidal cylinder transition phase 52, connect the linear portion 51 below the bottleneck of base body two ends and cylinder-shaped body section 53, make base body can realize stretching very smoothly, in the process stretched at whole bottle blowing like this, just avoid and form stretching turning, and then the apparent defect of impression or became uneven is produced in appearance in bottle-type, finally can realize the PET resin bottle-type of blowing the high bright similar glass bottle of outward appearance.
And contrast existing bottle base, as shown in Figure 1, the bottle base of prior art is still from top to bottom successively by 3 forming at the bottom of bottleneck 1, base body 2 and base.But what adopt in the transition phase 22 of base body 2 is that transition is steeper, the design that length is partially short, this transition phase 22 is when adding hot-stretch like this, enough intensity cannot be had to have connected linear portion 21 below the bottleneck of base body two ends and main paragraph 23, the gradient of base body main paragraph 23 is too little simultaneously, cannot coordinate the stretching of transition phase 22, when finally causing bottle blowing to stretch, bottle-type forms became uneven, cannot realize the bottle blowing effect of high bright bottle-type.
Preferred embodiment
Bottle base grammes per square metre: 23 grams; Bottle base length: 73 millimeters; Bottleneck lower straight segment length: 4.67 millimeters; Monolateral thickness: 2.19 millimeters; The outer bevel angle of trapezoidal cylinder transition phase: 21 degree 48 points; Interior bevel angle: 26 degree 20 points; Trapezoidal cylinder transition section length: 13 millimeters; Cylinder-shaped body segment length: 26.28 millimeters, thickness: 3.44 millimeters.
The gradient of base body cylinder-shaped body section simultaneously: 0 degree 18 points, the external diameter of cylinder-shaped body section: 23.83 millimeters; Base body bottleneck lower straight section and trapezoidal cylinder transition phase adopt the circular sliding slopes of R10; The trapezoidal cylinder transition phase of base body and cylinder-shaped body section adopt the circular sliding slopes of R30.
After implementing by technique scheme, use these 23 grams of bottle bases can blow range of capacity the bright bottle-type of height of 200 milliliters to 350 milliliters, and 250 milliliters of bottle-type of this programme bottle base blowing, plastics are evenly distributed, structural behaviour is good, bottle-type outward appearance is bright, visually almost as broad as long with glass bottle, product qualification rate reaching more than 99.5%.
Therefore, the utility model has the advantage of blowing high bright bottle-type.
But; those skilled in the art will recognize that; above-mentioned detailed description of the invention is exemplary; to better enable those skilled in the art understand the application; can not be interpreted as it is restriction to the application's protection domain; as long as according to the application disclose any equivalent change done of spirit or modification, all fall into the scope of the application's protection.
