Description

A kind of chemical raw material storage container

Technical field

The utility model belongs to chemical raw material technical field of memory, is specifically related to a kind of chemical raw material storage container with high obstructing performance.

Background technology

At present, along with the development in market and improving constantly of people's lives, people also constantly propose new requirement to the requirement of commodity packaging, the particularly storage of chemical raw material, require that storage container has good barrier property, go bad to avoid the material in container to hint obliquely at by ambient atmos, the packing container that the past adopts usually is glass container.

Because plastic packaging containers is compared with glass container, have lightweight, cost of transportation is low, can good decorative property, not easily broken, be suitable for premium properties such as transporting for long-distance especially, avoid the environmental pollution caused because packing container is damaged, as during by glass bottle packaging agricultural chemicals or other poisonous chemical products, serious environmental pollution can be caused after vial breakage.Compared with canister, it is low that they have again cost, the advantages such as machine-shaping is easy, are therefore also widely used in medical industry, food industry, cosmetics industry and chemical industry, as plastic bottle is used for packaged beverage, shampoo, chemical products and edible blend oil etc. widely.

But the common plastic containers be made up of a kind of raw material merely, because the chamber wall molecular gap of common plastic containers is very large, in air gas can penetrate bottle the asking gap of wall and enter container make the inside material go bad, that is their barrier property, particularly gas barrier properties, well below glass or canister, therefore its content easily goes bad, thus can only ensure that within shorter a period of time its content does not change, this is restricted with regard to making the range of application of these plastic containers.

Utility model content

The purpose of this utility model is solve above-mentioned technical problem and provide a kind of chemical raw material storage container with high obstructing performance.

For achieving the above object, the utility model adopts following technical scheme:
