Abstract
The invention discloses a kind of bottle base, 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 inwall entirety is straight line, described base body outer wall is positioned at below bottleneck and has outward-dipping changeover portion, and the main paragraph that described base body outer wall is positioned at below changeover portion slopes inwardly.The present invention has the advantage of the complicated bottle-type of blowing shoulder structure.
Description
Technical field
The present invention relates to a kind of bottle base, particularly relate to the bottle base being applicable to blow the complicated bottle-type of shoulder structure.
Background technology
In beverage industry, increasing along with product category, increasing enterprise, in order to attract the eyeball of consumer, puts into more energy in bottle-type appearance design, but constantly updating along with bottle-type outward appearance, structure day by day complicated.
As depicted in figs. 1 and 2, it is the ramp structure tilted inwards that existing bottle base adopts with the changeover portion 32 of base body 2 below bottleneck 1, such bottle base can not meet the blowing requirement of bottle-type, and especially for the bottle-type of shoulder structure complexity, existing bottle base especially cannot blow molding.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of bottle base can blowing the complicated bottle-type of shoulder structure, to overcome the deficiency of existing bottle base.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of bottle base, 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 inwall entirety is straight line, and described base body outer wall is positioned at below bottleneck and has outward-dipping changeover portion, and described base body outer wall is positioned at and slopes inwardly to the main paragraph below changeover portion.
In the present invention improves further, described base body outer wall also has the straightway parallel with base body inwall between changeover portion and bottleneck.
The outward-dipping 15-20 ° of described changeover portion, the thickest that described base body is positioned at the bottom position of described changeover portion is 4.4-5.5mm.
The main paragraph that described base body is positioned at below changeover portion slopes inwardly, and angle of inclination is 0.5-2.0 °.
The wall thickness that described base body is positioned at main paragraph position is 3.5-4.5mm.
Described base body inwall slopes inwardly 0.4-0.6 °.
The height of described straightway is 4-6mm, and described base body is to should the wall thickness of straight length portion be 1.5-2.5mm.
Adopt said structure, owing to forming an outward-dipping ramp structure below bottleneck with the transition position outer wall of base body, when when blowing shoulder structure complexity bottle-type, bottle base after heating, under the stretching action of stretching bar, first forms the transition product of a similar shuttle shape, and the maximum gauge place of this shuttle, namely most thick wall place, just in time corresponding bottle-type has the shoulder of labyrinth, is next aided with high pressure blow-gas again, just can guarantee that the shoulder place having labyrinth is shaping.
Therefore, the present invention has the advantage of the complicated bottle-type of blowing shoulder structure.

Detailed description of the invention
As shown in Figure 5 and Figure 6, bottle base of the present invention, from top to bottom successively by 3 forming at the bottom of bottleneck 1, base body 2 and base.
Wherein, on base body 2, inwall 21 entirety of base body 2 is straightway, and slightly slope inwardly 0.4-0.6 °.And the outer wall of base body 2, below bottleneck, be divided into straightway 31, changeover portion 32 and main paragraph 33 successively.Straightway 31 is parallel with inwall 21, is highly 4-6mm, and base body is to should the wall thickness of section part be 1.5-2.5mm; The outward-dipping angle of inclination of changeover portion 3 is 15-20 °; Base body 2 is to should the thickest place of section bottom be 4.4-5.5mm.Main paragraph 33 then slopes inwardly transition, and angle of inclination is 0.5-2.0 °, and base body 2 is to should the wall thickness of bottom (namely with junction at the bottom of base) of main paragraph 33 be 3.5-4.5mm.
Shown in composition graphs 7 and Fig. 8, owing to forming an outward-dipping inclined-plane below bottleneck 1 with the changeover portion place of base body 2, when when blowing shoulder structure complexity bottle-type, bottle base after heating, under the stretching action of stretching bar 001, first forms the transition product of a similar shuttle shape, and the maximum gauge place of this shuttle, namely most thick wall place, just in time corresponding bottle-type has the shoulder 6 of labyrinth, is next aided with high pressure blow-gas again, just can guarantee that shoulder 6 place having labyrinth is shaping.
And contrast existing bottle base, as shown in Figure 3 and Figure 4, it is the ramp structure tilted inwards that the bottle base of prior art adopts with the changeover portion of base body 2 below bottleneck 1, the wall thickness at this inclined-plane place is partially thin relative to other positions of base body like this, when blowing shoulder structure complexity bottle-type, bottle base after heating is under the stretching action of stretching bar 001, then form the transition product of a similar back taper, the shoulder 6 bottle-type having a labyrinth is then corresponding is the middle and lower part of back taper, wall thickness is relatively thin herein, when follow-up high pressure blow-gas, be difficult to shaping, or shaping rear wall thickness is too thin, strength character is not enough.
Preferred embodiment
Bottle base grammes per square metre: 74 grams; Bottle base length: 152 millimeters; Inwall entirety slopes inwardly 0.5 °, outer wall straightway: height 6 millimeters, the wall thickness at straightway place 2.1 millimeters; The angle of inclination on the inclined-plane of outer wall changeover portion: 18 °; Surface bottom thickest 4.5 millimeters, diameter 35.3 millimeters; Outer wall main paragraph slopes inwardly angle: 0.6 degree; Base body bottom: wall thickness 4 millimeters, diameter 32 millimeters;
After implementing by technique scheme, use these 74 grams of bottle bases to blow range of capacity is raised to 2.5 liters of shoulder shape complexity any bottle-type 1.8, and 1.9 litre flask types of this programme bottle base blowing, plastics are evenly distributed, structural behaviour is good, the bottle blowing speed of single mode 1200 bottles per hour can be realized, product qualification rate reaching more than 99.5%.
Therefore, the present invention has the advantage of the complicated bottle-type of blowing shoulder structure.
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.
