Abstract

The utility model discloses a kind of liquid-leakage preventing rubber stopper, including rubber cylinder, end face at described rubber cylinder forms the depressed part of oriented rubber cylinder inner recess, upwardly extends along place and wrap up rubber cylinder and the ring surface of glass bottle opening outer wall after being turned over downwards in the circle of depressed part;Described rubber cylinder outer wall is formed cannelure and lower cannelure, between twice cannelure, forms rubber ring.This utility model is close to bottle wall by ring surface, enhances the rubber stopper sealing property to vial, thus reduces the sample contamination caused due to ingress of air;Extend the holding time of sample especially volatile solvent soln;Prevent the unrestrained of solution during rocking, it is ensured that measure the accuracy of numerical value, saved experimental cost.This utility model sealing is strong, simple in construction, and it is convenient to open, and has broad application prospects.

Description

A kind of liquid-leakage preventing rubber stopper
Technical field
This utility model relates to the sealed piece of the container of object or storing material or transport, specifically a kind of liquid-leakage preventing Rubber stopper.
Background technology
In chemical analysis field, vial is commonly used to contain all kinds of solution, carries out close by compressing rubber stopper with bottleneck Envelope, but this bottle stopper sealing means is single, as shorter in run into the volatile solvent soln holding time, and at the solution of mixing configuration Time, need to rock up and down, owing to there being gap between bottle stopper and bottle wall, liquid easily flows out from gap, causes damage, both wasted Experiment material have impact on again the accuracy of numerical evaluation result.
Utility model content
This utility model is contemplated to solve the problem of vial rubber stopper seal of the prior art difference, is proposed A kind of liquid-leakage preventing rubber stopper.
This utility model realizes according to techniques below scheme.
A kind of liquid-leakage preventing rubber stopper, including rubber cylinder, the end face at described rubber cylinder is formed in oriented rubber cylinder The depressed part of portion's depression, has upwardly extended along place in the circle of depressed part and has wrapped up rubber cylinder and glass bottle opening after being turned over downwards The ring surface of outer wall;Described rubber cylinder outer wall is formed cannelure and lower cannelure, is formed between twice cannelure Rubber ring.
Described rubber cylinder is cylindrical or reverse frustoconic.
Described ring surface is upper and lower isometrical or the occluding surface of undergauge.
This utility model obtains following beneficial effect.
This utility model effectively solves the problem of vial rubber stopper seal difference in prior art.So design This utility model is close to bottle wall by ring surface, enhances the rubber stopper sealing property to vial, thus reduce due to The sample contamination that ingress of air causes;Extend the holding time of sample especially volatile solvent soln;Prevent during rocking Trickling down of solution, it is ensured that measure the accuracy of numerical value, saved experimental cost.This utility model sealing is strong, simple in construction, It is convenient to open, and has broad application prospects.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use state diagram of the present utility model.
Wherein: 1. ring surface 2. rubber cylinder
3. go up 4. times cannelures of cannelure
5. depressed part.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described further by embodiment.
As shown in Figure 1-2, a kind of liquid-leakage preventing rubber stopper, including rubber cylinder 2, the end face at described rubber cylinder 2 is formed The depressed part 5 of oriented rubber cylinder 2 inner recess, has upwardly extended along place in the circle of depressed part 5 and has wrapped up after being turned over downwards The ring surface 1 of rubber cylinder 2 and glass bottle opening outer wall;Described rubber cylinder 2 outer wall is formed cannelure 3 and lower annular Groove 4, forms rubber ring between twice cannelure.
Described rubber cylinder 2 is cylindrical or reverse frustoconic.
Described ring surface 1 is upper and lower isometrical or the occluding surface of undergauge.
Using method of the present utility model is: rubber cylinder 2 is slowly filled in glass bottle opening, when the end face of rubber cylinder 2 Slightly above stop during glass bottle opening, then ring surface 1 is turned over downwards and wraps rubber cylinder 2 and glass bottle opening outer wall, annular The design in face 1 enhances the sealing of rubber stopper;When taking off this utility model, flip up ring surface 1, with hands tractive ring surface Rubber cylinder 2 is extracted from bottleneck by 1.This utility model design is simple, easy to use, good sealing effect.
