Abstract
The utility model discloses a kind of PET bottle bases for being blow molded triangle bottle-type, including base mouth and base body, the base body includes base wall and base bottom, the lateral cross section of the base wall is circular ring shape, the outer diameter of the base wall from top to bottom gradually increases, the periphery wall tool of the base body is there are three thickening layer, and three thickening layers are distributed in the base body periphery wall, and the thickness of the thickening layer is gradually reduced from centre to both sides.The utility model is suitable for being blow molded the bottle of triangle bottle-type, and body uniform wall thickness, bottom of bottle is smooth, and blowing effect is good.
Description
Technical field
The utility model is related to a kind of PET bottle bases, and in particular to a kind of PET bottle base for being blow molded triangle bottle-type.
Background technology
In current PET bottle base product, shape is essentially all cylindrical, and cylindrical bottle base design difficulty is relatively
Small, corresponding mould structure is also fairly simple, easy to process, so existing PET bottle base is all the cylinder of rule.It is cylindrical
Bottle base have relatively good effect to blowing round or little length and width difference bottle, but blow the bottle of some triangle bottle-type
When, typical circular PET bottle base blowing after, body wall unevenness is even, at inner wall bottom of bottle present waveform, blowing effect it is poor,
Yield rate is low.Therefore, in order to avoid disadvantage existing in the prior art, it is necessary to make improvement to the prior art.
Utility model content
The purpose of the utility model is to overcome shortcoming and deficiency in the prior art, provide a kind of improve and are blow molded effect
PET bottle base for being blow molded triangle bottle-type.
The utility model is realized through the following technical scheme：
A kind of PET bottle base for being blow molded triangle bottle-type, including base mouth and base body, the base body include base wall and base
The lateral cross section at bottom, the base wall is circular ring shape, and the outer diameter of the base wall from top to bottom gradually increases, the periphery wall of the base body
For tool there are three thickening layer, three thickening layers are distributed in the base body periphery wall, and the thickness of the thickening layer is from centre to two
Side is gradually reduced.
Further, the lateral wall of the base mouth has screw thread, and locating slot is offered on the screw thread.
Further, the wall thickness of the base wall from top to bottom gradually increases.
Further, the thickness at the base bottom is less than or equal to the thickest of the base wall.
Compared with the existing technology, three thickening layers, this three thickenings are arranged by the periphery wall at base bottom in the utility model
The centre position of layer is adapted with the blow molding position at three angles end of triangle bottle-type so that the bottle body wall thickness of blow molding
Evenly, base bottom is more smooth, improves blowing effect.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram for the PET bottle base that the utility model is used to be blow molded triangle bottle-type；
Fig. 2 is the vertical view for the PET bottle base that the utility model is used to be blow molded triangle bottle-type.
In figure：1- base mouths；2- base bodies；3- base walls；4- bases bottom；5- thickening layers.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, it is clear that described embodiment is only the utility model a part of the embodiment, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
A kind of PET bottle base for being blow molded triangle bottle-type of the utility model as depicted in figs. 1 and 2, including 1 He of base mouth
Base body 2, base body 2 include base wall 3 and base bottom 4, and the lateral cross section of base wall 3 is circular ring shape, and the outer diameter of base wall 3 from top to bottom gradually increases
Greatly, the periphery wall tool of base body 2 is there are three thickening layer 5, and three thickening layers 5 are distributed in 2 periphery wall of base body, the thickness of thickening layer 5 by
Centre is gradually reduced to both sides.
The lateral wall of base mouth 1 has screw thread, and locating slot is offered on screw thread.The locating slot be conducive to blowing when and bottle blowing die
Positioning convex tendon be adapted, so that the position of thickening layer 5 and the position at three angles end of bottle blowing die is adapted.
The wall thickness of base wall 3 from top to bottom gradually increases, and makes the body thickness of blow molding evenly.
The thickness at base bottom 4 is less than or equal to the thickest of base wall 3, and the bottom of bottle for being conducive to blow molding is more smooth.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
