Abstract
The utility model relates to a high barrier property thermal insulation multi-layer plastic bottle, which comprises a bottle body, wherein the bottle body is composed of three layers or more than three layers of plastic walls; the material of a middle layer of the plastic walls adopts one of polycarbonate, polyethylene terephthalate or polyvinylidene chloride; the material of the other layers of the plastic walls adopts one of polycarbonate, mixture of polycarbonate and polyethylene terephthalate, or mixture of polycarbonate and polybutylene terephthalate, or polyvinylidene chloride; the total thickness of the bottle body is between 0.2MM to 3MM. The utility model with favorable gas barrier performance is suitable for packing of biological products, medicine, food and drink which have high requirements of gas tightness.
Description
One, technical field
The utility model relates to plastic container, and particularly the laminated plastics bottle is made the field.
Two, background technology
Plastic bottle is widely used in multiple product packing aspect as packing container.For medicine, especially the biological species medicine holds, just require secluding air at memory period, vacuumizing or additive method keeps amount of air near zero at the bottle inner chamber after removing air, in other words, promptly in long-time storing process, do not allow outside air (mainly being oxygen in the air) to infiltrate through the bottle wall.In addition, requirement has at least 120 ℃ of high temperature of tolerance and indeformable resistance to heat because sterilization needs also for food, beverage, drug packaging bottle.And existing monolayer plastic bottle such as polyethylene bottle or PVC bottle can not reach this requirement to the iris action and the heat resistance of gas.
Three, utility model content
The purpose of this utility model provides a kind of barrier temperature-resistant multi-layer plastic bottle, is intended to improve barrier property and resistance to elevated temperatures to gas.This later-model purpose realizes through following technical scheme: a kind of high barrier temperature-resistant multi-layer plastic bottle, comprise bottle, it is characterized in that, described bottle is made up of the plastics wall more than three layers or three layers, its interlayer plastics wall material is selected a kind of of polycarbonate, polyethylene terephthalate or polyvinylidene chloride for use, and the material of other layer plastics wall is selected a kind of of the compound of the compound of polycarbonate, polycarbonate and polyethylene terephthalate or polycarbonate and polybutylene terephthalate or polyvinylidene chloride for use; The gross thickness of bottle is between 0.2-3mm.
From technique scheme, (interlayer also refers to laminboard layer to the interlayer of this later-model laminated plastics wall, as for 3 layers of bottle, the 2nd layer is interlayer, for 4 layers of bottle, 2nd, 3 layers all can be interlayer, in the case, then with the 2nd layer or the 3rd layer be interlayer all can) material be polycarbonate, polyethylene terephthalate or polyvinylidene chloride, compare with the common polythene plastics, the three all has higher serviceability temperature and physical strength and better gas barrier property.Simultaneously, this is novel in the multi-layer forming process, generally adopts multilayer bottle manufacturing equipment to make ground floor plastics wall according to the order of sequence, second layer plastics wall, three-layer plastic wall or the like.Since between adjacent layer the mol wt of (having one at least) High molecular material can be variant or material through modification, the steric configuration of molecule may be inequality, after such bottle wall more than three layers or three layers is superimposed with each other, iris action to gas is just better than the plastic bottle that single-layer resin forms, the whole air-tightness of bottle is improved, secondly, ectonexine all adopts the heatproof plastics, and the resistance to elevated temperatures of bottle also is improved.
Four, description of drawings
Accompanying drawing is the constructional drawing of this novel embodiment.
Five, the specific embodiment
Accompanying drawing illustrates, bottle is made up of plastics wall more than three layers or three layers (wall is made up of bottom and sidewall), its interlayer plastics wall material is selected a kind of of polycarbonate, polyethylene terephthalate or polyvinylidene chloride for use, the material of other layer plastics wall is selected compound or the compound of polycarbonate and polybutylene terephthalate or a kind of (fire resistant resin) of polyvinylidene chloride of polycarbonate, polycarbonate and polyethylene terephthalate for use, and the gross thickness of bottle is between 0.2-3mm.Especially, comparable its sidewall in the bottom of whole bottle is thick.
Embodiment 1
With three layers of bottle is example, and its structure is: ground floor plastics wall 1 is the compound of polycarbonate and polyethylene terephthalate from inside to outside; Second layer plastics wall 2 is a polycarbonate, and three-layer plastic wall 3 is identical with the material of ground floor, and bottle is transparent.
Embodiment 2
With three layers of bottle is example, and its structure is: bottle ground floor from inside to outside is a polycarbonate, and the second layer is a polyethylene terephthalate, and the 3rd layer is polycarbonate, and bottle is transparent.
Embodiment 3
With three layers of bottle is example, and its structure is: bottle ground floor from inside to outside is a polycarbonate, and the second layer is a polyethylene terephthalate, and the 3rd layer is the compound of polycarbonate and poly terephthalic acid ethanol ester, and bottle is transparent.
Embodiment 4
With three layers of bottle is example, and its structure is: bottle ground floor from inside to outside is a polycarbonate, and the second layer is a polyvinylidene chloride, and the 3rd layer is polycarbonate, and bottle is transparent or semitransparent.
Embodiment 5
With three layers of bottle is example, and its structure is: bottle ground floor from inside to outside is a polycarbonate, and the second layer is the polyvinylidene chloride modified plastics, and the 3rd layer is the compound of polycarbonate and polyethylene terephthalate, and bottle is translucent or opaque.
Embodiment 6
With three layers of bottle is example, and its structure is: bottle ground floor from inside to outside is a polycarbonate, and the second layer is a polycarbonate, and the 3rd layer is the compound of polycarbonate and polyethylene terephthalate.
Embodiment 7
