CN201400338Y - Plastic bottle parison - Google Patents

Abstract

The utility model discloses a plastic bottle parison with an internal interlayer and the interlayer vertically separates the bottle parison interior into two relatively independent cavities that are not communicated with each other. The plastic bottle parison is a transmitting product in the course of plastic bottle blowing; and a plastic material is processed into a bottle parison which is then placed on a blower to be blown for forming. The existing plastic bottle parison is a single-cavity bottle parison, which is not suitable for the blowing of a double-cavity or multi-cavity bottle. The plastic bottle parison is applicable to blow a double-cavity plastic bottle and changes the shape of the interlayer, i.e. triple-cavity or multi-cavity plastic bottles can be made, thus meeting the blowing requirement of double-cavity, triple-cavity or multi-cavity plastic bottles.

Description

A kind of plastic bottle blank

Technical field

The utility model relates to a kind of plastic bottle blank, and particularly a kind of inside has the plastic bottle blank of interlayer.

Background technology

Plastic bottle blank is the excessive product before plastic bottle is shaped.Before the plastic bottle blowing, plastic raw materials be made plastic bottle blank, then, plastic bottle blank is placed in the bottle blowing machine blowing.Existing plastic bottle blank all is one one chamber, the also plastic bottle in one one chamber just of blowing, and be inapplicable for one two chambeies or multi-cavity plastic bottle.

The utility model content

Task of the present utility model provides a kind of plastic bottle blank that is used to blow one two chambeies or one multi-cavity plastic bottle.

Bottle base described in the utility model has interlayer, and interlayer vertically is divided into two relatively independent and not connected chambeies with plastic bottle blank base substrate inside, forms one two chamber plastic bottle blanks.The conversion interlayer be shaped as " Y " font or "+" font, can obtain one three chamber bottle bases or one four chamber bottle bases respectively.Thereby satisfy the blowing of one two chambeies, one three chambeies, one multi-cavity plastic bottle.

Figure four is "+" font bottle base mansion views

The specific embodiment

With reference to figure one, figure two, the plastic bottle blank that has interlayer 2 processes with base substrate 1, forms an integral body, and interlayer 2 vertically is divided into two independent and not connected chambeies with the inside of plastic bottle blank base substrate 1, forms one two chamber plastic bottle blanks.

In like manner, with reference to figure three,, obtain one three chamber plastic bottle blanks when interlayer 2 is processed as " Y " font.With reference to figure four,, obtain one four chamber plastic bottle blanks when interlayer 2 is processed as "+" font.Along with interlayer 2 shapes more change, promptly obtain one multi-cavity plastic bottle blank according to this, thereby satisfy the blowing of one two chambeies, one three chambeies, one multi-cavity plastic bottle.

Claims (2)

1, a kind of plastic bottle blank is characterized in that plastic bottle blank inside is provided with interlayer (2), and interlayer (2) is with inner two relatively independent and not connected chambeies, the formation one two chamber plastic bottle blanks of vertically being divided into of plastic bottle blank base substrate (1).

2, plastic bottle blank according to claim 1, what it is characterized in that conversion interlayer (2) is shaped as " Y " font or "+" font, can obtain one three chamber bottle bases or one four chamber bottle bases respectively.
