Description

High added value presser for liquid reagent bottle

Technical field

The utility model relates to reagent bottle, more particularly, relates to a kind of high added value presser for liquid reagent bottle.

Background technology

The Packaging Bottle of chemical reagent, particularly liquid reagent generally more adopts coloured glass bottle, and uses plastic bottle closure to be sealed by screwed tight.Because a lot of chemical reagent has very strong corrosive property, volatility, in long-term preservation process, very high request is proposed to the leak tightness of reagent bottle.

At present, traditional reagent bottle adopts bottle cap to be generally a circle half or two circle screw thread, and the binding force of bottle cap and bottleneck is reported to the leadship after accomplishing a task, and easily leaks; Further, bottleneck inwall is through state, and having strong volatile liquid reagent directly can produce certain impulsive force to bottle cap, causes easily leaking; In addition, in bottle cap, the general packing seal adopted is rubber pad, or does not adopt packing seal, and sealing property is poor, is not suitable for the reagent packaging high to seal request.

In addition, current reagent bottle mostly is 250ml, 500ml equal-specification, but, high for some added values, with the reagent of dosage few (as 5 ~ 30ml), also there is no the reagent bottle of corresponding special high leakproofness.

Utility model content

The purpose of this utility model aims to provide a kind of high added value presser for liquid reagent bottle, is exclusively used in high added value liquid reagent, and has good airproof performance, avoids the advantages such as leakage occur.

This high added value presser for liquid reagent bottle, comprise the body of flash glass, the bottle cap of plastics, this bottle cap is connected with the bottleneck of body by screw thread, bottle cap inner top is also provided with packing seal, and described bottleneck inwall end is provided with arc angling, and the screw thread of described bottle cap is more than four circles, the screw thread of described bottleneck and the screw thread of bottle cap suitable, described bottleneck is also provided with inner cap, inside covers the liquid return trough being provided with a circle indent, the circle centre position of liquid return trough is provided with a minim pipette.

The top of described minim pipette is lower than inner cap upper surface.

Described packing seal is polytetrafluoroethylmaterial material, and in disc, surrounding and bottle cap are fitted fixing, middle to lower convexity.

Described screw thread is four circles.

Described bottle cap lower end is also connected with anti-theft ring, and anti-theft circular sleeve is located at bottleneck.

Described bottle base thickness degree is at more than 5mm, and upper surface at the bottom of bottle is plane, and lower surface is inner concave arc surface.

Described body capacity is 5-50ml.

High added value presser for liquid reagent bottle of the present utility model comprises the body of flash glass, the bottle cap of plastics, this bottle cap is connected with the bottleneck of body by screw thread, bottle cap inner top is also provided with packing seal, described bottleneck inwall end is provided with arc angling, the screw thread of described bottle cap is more than four circles, the screw thread of described bottleneck and the screw thread of bottle cap suitable, described bottleneck is also provided with inner cap, inside cover the liquid return trough being provided with a circle indent, the circle centre position of liquid return trough is provided with a minim pipette.Designed by the arc angling of bottleneck; can increase the area of contact of bottleneck and bottle cap, anti-leakage is extremely strong, and arc angling can also play certain stop and suppression to the gas that strong volatile reagent produces; thus play protection bottleneck and bottle cap, further increase leak tightness.By increasing thread turns, effectively can increase the area of contact of bottle cap and whorl of bottleneck, greatly improving the binding force of bottle cap and bottleneck, making leakproof, anti-corrosion performance significant increase.Adopt the packing seal of polytetrafluoroethylene material, there is extremely strong anticorrosive property and toughness, ensure that the perfection of bottle cap and bottleneck is fitted.The fine-still of high added value reagent can be facilitated to use by minim pipette, and unnecessary dropping liquid can be reclaimed by liquid return trough.

Detailed description of the invention

The technical solution of the utility model is further illustrated below in conjunction with drawings and Examples.

Refer to shown in Fig. 1 ~ Fig. 4, what high added value presser for liquid reagent bottle of the present utility model was same as the prior art is, equally also comprise the body 1 of flash glass, the bottle cap 2 of plastics, this bottle cap 2 is connected by the bottleneck of screw thread 3 with body 1, and bottle cap 2 inner top is also provided with packing seal.Unlike the prior art; described body capacity is designed to 5ml, 10ml, 15ml according to actual needs ... the low capacities such as 50ml; and described bottleneck inwall end is provided with arc angling 4; this chamfering 4 makes bottleneck upwards tighten up; design like this; not only can increase the area of contact of bottleneck and bottle cap 2; make its anti-leakage extremely strong; but also certain stop and suppression can be played to the gas that strong volatile reagent produces; thus play protection bottleneck and bottle cap 2, further increase leak tightness.

Further, the screw thread of described bottle cap is more than four circles, and the screw thread 3 of described bottleneck is suitable with the screw thread 3 of bottle cap 2.So, the increase of bottle cap 2 screw thread 3 quantity, greatly increases the foundation area of bottle cap 2 and whorl of bottleneck 3, greatly improves the binding force of bottle cap 2 and bottleneck, makes leakproof, anti-corrosion performance also has great lifting.As a preferred embodiment, described screw thread 3 is designed to four circles.

Described bottleneck is also provided with inner cap 7, and inner cap 7 lower end is fixed in bottleneck, and inner cap 7 upper end is provided with the liquid return trough 8 of a circle indent, and the circle centre position of liquid return trough 8 is provided with a minim pipette 9, and in order to fine-still reagent, the top of described minim pipette 9 is a little less than inner cap 7 upper surface.

And the effect of liquid return trough is: at the end of fine-still reagent, if when having reagent to spill to flow down along minim pipette 9 outer wall, collects by liquid return trough, avoid polluting.

Described packing seal is the disc suitable with bottle cap 2 inner top, surrounding and the bottle cap 2 of packing seal fit fixing, the centre of packing seal then to lower convexity, when bottle cap 2 is tightened mutually with bottleneck, to carrying out effective sealing, overall tightness can be improved further by packing seal.Sealing pad can adopt polytetrafluoroethylmaterial material, has extremely strong anticorrosive property and toughness, can ensure that bottle cap 2 is fitted with the perfection of bottleneck.

Described bottle cap 2 outer wall is also evenly provided with the fricting strip 5 of several vertical bar shape, conveniently screws, bottle cap 2 lower end is also connected with disposable pilfer band (not shown), and anti-theft circular sleeve is located at bottleneck.

At the bottom of described bottle, 6 Thickness Design are at more than 5mm, and at the bottom of bottle, 6 upper surfaces are plane, and lower surface is inner concave arc surface, and such shape is convenient to the processing of low capacity body, too increase intensity and the crushing resistance of bottom simultaneously.

Those of ordinary skill in the art will be appreciated that, above specification sheets is only one or more embodiments in the numerous embodiment of the utility model, and not with to restriction of the present utility model.Any equalization for the above embodiment changes, modification and the equivalent technical scheme such as to substitute, as long as meet spirit of the present utility model, all will drop in scope that claims of the present utility model protect.
