Description

With the reagent bottle of plastic packaging

Technical field

The utility model relates to liquid reagent packaging, more particularly, relates to a kind of reagent bottle with plastic packaging.

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 depth of thread generally at 0.5-1mm, thus makes the binding force of bottle cap and bottleneck, 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.

Utility model content

The purpose of this utility model aims to provide a kind of reagent bottle with plastic packaging, can improve leak tightness, avoids leaking, and is conducive to the preservation of reagent.

The reagent bottle of this band plastic packaging comprises the body of 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 three circles, and depth of thread is more than 1.5mm, the screw thread of described bottleneck and the screw thread of bottle cap suitable; Described bottle cap is also provided with plastic packaging film.

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

Described packing seal is polytetrafluoroethylmaterial material.

Described screw thread is three circles.

Described depth of thread is 1.8mm.

Described plastic packaging film extends downwards and has wrapped up whole body, and is provided with tear line being positioned on the plastic packaging film on bottleneck.

Described plastic packaging film is HDPE material, and thickness is 20.

The reagent bottle of band plastic packaging of the present utility model comprises the body of 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 three circles, and depth of thread is more than 1.5mm, the screw thread of described bottleneck and the screw thread of bottle cap suitable, described bottle cap is also provided with plastic packaging film.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 and the degree of depth, 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.Certain protective effect can be played to bottle cap and body by HDPE plastic packaging film, further raising is played to integral sealing, also be conducive to the long-term preservation of reagent simultaneously.

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 the reagent bottle of band plastic packaging 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 bottleneck inwall end is provided with arc angling 4; the bottleneck that this chamfering 4 is upwards tightens 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.

And, described bottle cap 2 is also provided with plastic packaging film 7, this plastic packaging film 7 extends into bottleneck downwards, by bottleneck surrounding parcel main (see Fig. 1), certainly can also extend downwards and whole body 1 be wrapped up (sealing effectiveness is better), and on the plastic packaging film 7 be positioned on bottleneck, be provided with tear line 8, be convenient to tear plastic packaging film 7 in use.

Described plastic packaging film 7 can adopt high density polyethylene (HDPE) (High Density Polyethylene, referred to as " HDPE ") material, and thickness is 20.Certainly, other capsulation materials can also be adopted.

By above-mentioned plastic packaging film 7, certain protective effect can be played to bottle cap 2 and body 1, further raising is played to integral sealing, also be conducive to the long-term preservation of reagent in bottle simultaneously.

Further, the screw thread 3 of described bottle cap 2 is designed to more than three circles, and screw thread 3 depth design is more than 1.5mm, and the screw thread 3 of described bottleneck is suitable with the screw thread 3 of bottle cap 2.So, bottle cap 2 screw thread 3 quantity and the degree of depth increase, and greatly increase the foundation area of bottle cap 2 and whorl of bottleneck 3, greatly improve the binding force of bottle cap 2 and bottleneck, make leakproof, anti-corrosion performance also has great lifting.

As a preferred embodiment, described screw thread 3 is designed to three circles, and described screw thread 3 depth design is 1.8mm.

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, effective sealing can be carried out to bottleneck by packing seal, improve overall tightness further.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 provided with pilfer band 6, can play anti-theft function.

In addition, can also, by suitably increasing bottle cap 2 thickness, play shockproof, breakage-proof, anticracking, corrosion prevention, increases degree of damping, is convenient to the effects such as client opens.

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.
