The outside of the taper plastic burette is arranged with a taper plastic burette cap matched with the shape. The plastic drop bottle has an easy operation, and the amount of the reagent can be fetched precisely, which can effectively avoid the pollution and waste of the reagent, prolong the durability of the drop bottle and the reagent and reduce the experiment cost. The utility model is applicable for various experimenting institutions to make the experiments such as chemistry and medication.

Description

Convenient squash type plastic dropping bottle

Technical field

The utility model relates to the reagent drop bottle that uses in the chemical laboratory, refers to a kind of convenient squash type plastic dropping bottle particularly.

Background technology

At present, the reagent drop bottle overwhelming majority or the glassware used always in the chemical laboratory mainly are made up of glass ground joint bottle, glass dropper and Rubber end three parts.Blow-by between the reagent drop bottle ubiquity bottle of this glass structure and the dropper, solvent or reagent is the deficiency of volatilization easily, causes chemical reagent and airborne oxygen generation chemical action and pollutes or go bad.What is more, and all ingredients that leaves in the drop bottle in the reagent cabinet usually carries out gas-phase reaction because of poorly sealed by environment, thereby cause environmental pollution and cause the corrosion of Laboratory Instruments equipment.In addition, this glass dropper bottom thin is easily fractureed, Rubber end is also easily by the chemical reagent corrosion-deformation, and practical operation must be very careful, thereby exists reagent to take the short partially defective in service life of inconvenience, reagent dosage difficult accurately grasp, drop bottle.

Summary of the invention

The purpose of this utility model will solve the existing in prior technology deficiency exactly, provide a kind of easy and simple to handle easily, the reagent amount of getting accurately, can effectively avoid the relative convenient squash type plastic dropping bottle of growing of reagent contamination with waste and service life.

For achieving the above object, the convenient squash type plastic dropping bottle that the utility model is designed, have a plastic bottle body and the close-connected plastic outer cover of the bottleneck thread with plastic bottle body, described plastic bottle body is the flexible plastic bottle, be provided with the conical plastic dropper that a manufacturing integrated with it forms above the described plastic outer cover, the awl bottom branch of described conical plastic dropper directly communicates with the flexible plastic bottle, the cone top part of described conical plastic dropper is divided into sharp mouth liquid droping port, and the outside of described conical plastic dropper is provided with a conical plastic dropper cap that is complementary with its shape.

Advantage of the present utility model is, designed drop bottle is mainly combined by tight connection of plastic outer cover screw thread of flexible plastic bottle and band conical plastic dropper, except that sharp mouth liquid droping port, whole drop bottle constitutes a closed system, and the outside design of sharp mouth liquid droping port has had the conical plastic dropper cap of dustproof effect, and the tight structure of on the one hand this enclosing cover screw thread envelope, the tiny sharp mouth liquid droping port structure of far-end and conical dropper cap can prevent effectively that reagent from leaking outside, avoiding reagent contaminated with extraneous the contact; Whole on the other hand drop bottle adopts alkaline-resisting oxidation resistant plastic material to make, and has very long service life, except that the concentrated sulfuric acid and two kinds of strong oxidising agents of nitric acid can not use, but the equal splendid attire of other reagent, and be convenient to take, storage and transport; Simultaneously, only need push the flexible plastic bottle gently, just can take the reagent in the drop bottle easily, and the tiny sharp mouth liquid droping port of diameter is easy to accurately control reagent dosage, be very suitable for various experiment mechanism and carry out experiments such as chemistry, medicine.

Description of drawings

Accompanying drawing is a kind of main sectional structure schematic diagram of convenient squash type plastic dropping bottle.

The specific embodiment

Below in conjunction with accompanying drawing and example convenient squash type plastic dropping bottle of the present utility model is described in further detail:

Convenient squash type plastic dropping bottle shown in the figure is made up of plastic outer cover 2 and a conical plastic dropper cap 3 of a flexible plastic bottle 1, a band conical plastic dropper 5.Plastic outer cover 2 is connected by the screw thread tight seal with the bottleneck of flexible plastic bottle 1, can prevent that reagent from leaking outside.Above the plastic outer cover 2 be and the conical plastic dropper 5 of its integrated extrusion molding, the awl bottom branch of conical plastic dropper 5 is engaged on the plastic outer cover 2, and it directly communicates with flexible plastic bottle 1 inner chamber; The cone top part of conical plastic dropper 5 is divided into sharp mouth liquid droping port, and the every amount of reagent that can ooze is as required set the diameter of this liquid droping port.The outside of conical plastic dropper 5 is supporting to be provided with a conical plastic dropper cap 3, it can be put when not taking reagent, prevents that test solution is by dust pollution.What be provided with above the bottleneck of flexible plastic bottle 1 and between the inboard of plastic outer cover 2 that a polytetrafluoroethylmaterial material makes compresses seal washer 4, can not reveal by the junction of two parts further to guarantee reagent.Flexible plastic bottle 1 is preferably translucent flexible plastic bottle 1, and the scale marker of expression reagent liquid level is set on its body, and drop bottle had both had the alkaline-resisting oxidation resistant long-life like this, is convenient to again directly observe and operation.The utility model only need push flexible plastic bottle 1 in use slightly, and reagent wherein can ooze by conical plastic dropper 5, and the consumption of reagent is easy to control, and is convenient to operation.
