Abstract

The utility model relates to a bilayer PET (Polyethylene Terephthalate) bottle, comprising an inner layer and an outer layer. The inner layer is a hollow cavity surrounded by a bottle neck, a bottle body and a bottle bottom, the outer layer covers the exterior of the inner layer, and the distance between the outer layer and the inner layer is within 0-10mm. The bilayer PET bottle disclosed by the utility model is not easy to deform and improves storage quality.

Description

A kind of double-layer PET bottle

Technical field

The utility model belongs to packaging field, is specifically related to a kind of double-layer PET bottle.

Background technology

PET is the saturated polyester that terephthalic acid and ethanediol are polymerized for " gathering terephthaldehyde's diethylester " (Polyethylene Terephthalate); Itself have the good transparency, glossiness and gas barrier property; Meet the foodsafety standard, and recyclable processing is used again.The PET bottle is owing to light weight, and keeping quality is good, and is emphasical heat-resisting, withstand voltage, functions such as low environment contaminative and energy resource consumption property, and make the PET bottle become the main material of drinking packing the today that comes back in environmental consciousness.

Along with the continuous progress of science and technology and the scale of production, PET bottle blowing machine degree of automation is increasingly high, and production efficiency is also increasingly high.Equipment capacity improves constantly, and is developed into by several thousand bottles of per hour production and per hour produces several ten thousand bottles now in the past.Along with the increase of quantity, requirements for quality also needs progressively to improve.Some PET bottles in the market exist yielding, are prone to break, thus the quality of interior dixie cup of influence or object.So making a kind of solid and reliable bottle is urgent problem.

Summary of the invention

Goal of the invention: the purpose of the utility model is in order to overcome deficiency of the prior art, to provide a kind of not yielding, improving the double-layer PET bottle of preserving quality.

Technical scheme: in order to solve the problems of the technologies described above; The described double-layer PET bottle of the utility model; It comprises internal layer and skin, and said internal layer is by bottleneck, the hollow reservoir that the bottle and the bottle end surround; It is outside that said skin is wrapped in said internal layer, and the distance between said skin and the internal layer is between 0-10mm.

Said outer field thickness is between 1-5mm.

Be provided with handle at said outer field neck.

Said handle be shaped as circle, oval and square.

Beneficial effect: the utility model compared with prior art; Its remarkable advantage is: the internal layer coated outside layer of protecting formula at the utility model is outer; Improve the anti-extrusion degree of bottle, made integral structure more firm, thereby guaranteed the quality of object in the bottle.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, the described a kind of double-layer PET bottle of the utility model, it comprises internal layer 1 and outer 2; Said internal layer 1 is by bottleneck 3; The hollow reservoir that bottle 4 and the bottle end 5 surround, said outer 2 are wrapped in said internal layer 1 outside, said outer 2 and internal layer 1 between distance between 0-10mm; Said outer 2 thickness is between 1-5mm; Be provided with handle 6 at said outer 2 neck; Said handle 6 be shaped as circle, oval and square.The internal layer coated outside of the utility model the layer of protecting formula outer, improved the anti-extrusion degree of bottle, make integral structure more firm, thereby guaranteed the quality of object in the bottle.

The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
