Abstract

The utility model relates to the field of plastic bottle product structures, in particular to a double-wall plastic bottle. The double-wall plastic bottle comprises an inner bottle wall which is made of polyethylene. The double-wall plastic bottle is characterized in that the double-wall plastic bottle further comprises an outer bottle wall which is made of polypropylene, and the outer bottle wall and the inner bottle wall are bonded together. With the structure being adopted, the inner bottle wall made of the polyethylene guarantees holding feel and forming strength of a product, wrapping of the outer bottle wall made of the polypropylene enables the surface of the product to have enough brightness, and attractiveness of the product appearance is improved.

Description

The double-walled plastic bottle

Technical field

The utility model relates to plastic bottle product structure field, is specially a kind of double-walled plastic bottle.

Background technology

Plastic bottle is widely used in daily life, yet plastic bottle in the market mostly is single-wall structure, and with polyethylene (polyethylene, be called for short PE) for raw material carries out blowing production, so, the plastic bottle body of output does not exist luminance brightness high or hold good, the not stiff problem existence of sense.

Summary of the invention

The purpose of this utility model is, provides that a kind of luminance brightness own is high, the bottle flexibility is good, holds the plastic bottle of the comfortable double-walled construction of sense.

In order to achieve the above object, the utility model is achieved in that

A kind of double-walled plastic bottle, it comprises the inner bottle wall of being made by polyethylene, also comprises the outer blank wall of being made by polypropylene; Described outer blank wall wraps up inner bottle wall fully, and outer blank wall and inner bottle wall are bonding.

Described double-walled plastic bottle, the making material of described polyethylene inner bottle wall is HDPE 5502, the making material of described polypropylene outer blank wall is PP ST611.

Described double-walled plastic bottle, the inner bottle wall that polyethylene is made accounts for 80% of bottle quality; The outer blank wall that polypropylene is made accounts for 20% of bottle quality.

The utility model adopts the said structure design; The polyethylene inner bottle wall guaranteed product hold the sense and shaping strength, the parcel of polypropylene outer blank wall makes product surface have enough luminance brightness, has improved the aesthetics of product appearance.

Description of drawings

Fig. 1 is the schematic diagram that partly cuts open of the present utility model.

Fig. 2 is the partial enlarged drawing of Fig. 1.

The specific embodiment

Below further illustrate the utility model by specific embodiment.

As shown in Figure 1 and Figure 2, a kind of double-walled plastic bottle, it comprises the inner bottle wall 2 of being made by high density polyethylene (HDPE) (HDPE5502), also comprises the outer blank wall 1 of being made by high transparent polypropylene (PP ST611); Described outer blank wall 1 wraps up inner bottle wall 2 fully, and outer blank wall 1 is bonding with inner bottle wall 2.

Described double-walled plastic bottle, the inner bottle wall 2 that polyethylene is made accounts for 80% of bottle quality; The outer blank wall 1 that polypropylene is made accounts for 20% of bottle quality.

The utility model adopts the said structure design; The polyethylene inner bottle wall guaranteed product hold the sense and shaping strength, the parcel of polypropylene outer blank wall makes product surface have enough luminance brightness, has improved the aesthetics of product appearance; Simultaneously, adopt blow molding process when this double-walled plastic bottle is made, inner bottle wall and the moulding of outer blank wall when improving the product aesthetics, have been saved manufacturing cost.

Claims
