Description

Technical Field

[0001] The utility model relates to the technical field of corrosive chemical reagents, in particular to an inner cover of a corrosive liquid reagent bottle. Background Art

[0002] In chemical laboratories, corrosive liquid reagents are often used, such as hydrochloric acid, sulfuric acid, nitric acid and phosphoric acid. Because they are corrosive and dangerous, and liquid reagents are easy to leak from reagent bottles, reagent bottles containing corrosive liquid reagents are often equipped with inner covers inside the outer covers to increase sealing and prevent leakage of corrosive liquid reagents.

[0003] Because the inner cover is tightly combined with the reagent bottle, it is very difficult to open the cover. In addition, because liquid reagents are contaminative, during the repeated opening and closing process, the outer side of the inner cover and the mouth of the reagent bottle are often contaminated with corrosive liquid reagents. If it is opened directly by hand, there is a great safety hazard. Furthermore, during the filling, transportation and storage of the reagent, the ambient temperature will change, and negative pressure may be generated in the reagent bottle. In this case, it will be more difficult to open the inner cover.

[0004] Many patents have proposed special tools for opening reagent bottle caps, such as CN202311516838.1 a reagent bottle cap opener, CN202321988609.5 a reagent bottle automatic cap opener, CN202223448873.8 a reagent bottle cap opening pliers, etc. These tools are special tools and can only be used to open reagent bottle caps and cannot be used for other purposes. They have a narrow range of use, and the structures of these tools are relatively complex, so they are not easy to popularize. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a reagent bottle inner cover which is simple in structure, easy to open, low in manufacturing cost, and can be used in conjunction with general hardware tools. During the opening process, the hands of the experimenter do not contact the inner cover and the bottle mouth, thus avoiding the damage of the corrosive liquid reagent to the hands.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model relates to an inner cover of a corrosive liquid reagent bottle, comprising a cover edge and a cover body, wherein a vertical plate is arranged in the cover body.

[0008] Furthermore, the vertical plate is connected to the bottom surface of the cover body and the side surface of the cover body through the axis of the cover body.

[0009] Furthermore, the height of the vertical board is flush with the cover edge.

[0010] Furthermore, horizontal stripes are provided on both sides of the vertical plate at the center position of the vertical plate along the axial direction of the cover body.

[0011] Furthermore, the inner cover is made of plastic.

[0012] When opening the inner cover of the reagent bottle proposed by the utility model, the operation can be completed using universal hardware tools such as needle-nosed pliers or general pliers. The specific operation method is: hold the body of the reagent bottle with one hand, and use needle-nosed pliers or general pliers to clamp the horizontal cross-striped part of the vertical plate with the other hand, and pull it upward to open the inner cover. After use, use needle-nosed pliers or pliers to put the inner cover back, and then rinse the corrosive liquid reagent contaminated on the front end of the needle-nosed pliers or pliers with clean water. In the process of opening the inner cover and putting the inner cover back, there is no need to touch the mouth of the reagent bottle and the inner cover with your hands, which can effectively prevent the corrosive liquid reagent from harming the human body. In addition, needle-nosed pliers and pliers make it easier for people to apply force to the inner cover, making the inner cover easier to open.

[0013] Needle-nosed pliers or pliers are hardware tools commonly used in general scientific research laboratories, which are cheap and easy to obtain. The reagent bottle inner cover proposed by the utility model has the characteristics of being able to be used in conjunction with general hardware tools, so that the utility model has the advantages of strong practicality and easy popularization.

[0014] The height of the vertical plate of the inner cover of the reagent bottle proposed by the utility model is flush with the cover edge. The height of the vertical plate does not exceed the height of the cover body, and does not affect the outer cover pressing the inner cover. When the outer cover is tightened, the outer cover presses the inner cover, so that the inner cover seals the reagent bottle more tightly. If the height of the vertical plate is lower than the height of the cover body, when using needle-nosed pliers or pliers to clamp the inner cover, the force area is reduced, which is not conducive to the clamping operation.

[0015] The vertical plate not only provides a position for clamping with needle-nosed pliers or pliers, but also increases the strength of the inner cover, reduces the deformation of the inner cover, and acts as a reinforcing rib.

[0016] The vertical plate of the reagent bottle inner cover provided by the utility model is provided with horizontal stripes on both sides, and the horizontal stripes can increase the friction of the vertical plate to prevent slipping when the inner cover is clamped by needle-nosed pliers or pliers.

[0017] The inner cover of the reagent bottle proposed by the utility model is made of plastic material. The plastic material is soft and has certain toughness and elasticity, and can be well matched with the bottle mouth of the glass reagent bottle to achieve certain water tightness and air tightness. The plastic material has stable chemical properties and does not react with general corrosive liquid reagents. The plastic material is cheap and easy to obtain, and the cost of making the inner cover is low.

[0018] The beneficial effects of the utility model are:

[0019] (1) The inner cover of the corrosive liquid reagent bottle provided by the utility model can be used in conjunction with general hardware tools, is highly practical, and is easy to popularize.

[0020] (2) You can use needle-nosed pliers or ordinary pliers to open the inner cover of the reagent bottle, making the opening operation easier by applying force to the inner cover. The opening operation is easier than opening it with bare hands.

[0021] (3) When opening the inner cover, there is no need to touch the inner cover with your hands, which can effectively prevent the corrosive liquid reagents from harming the human body.

[0022] (4) The vertical plate serves as a reinforcing rib, which can enhance the strength of the inner cover and reduce the deformation of the inner cover.

[0023] (5) The height of the vertical plate is flush with the edge of the cover, which does not affect the tightening of the outer cover. The inner and outer covers are used together to achieve better sealing.

[0024] (6) The vertical plate with horizontal stripes can increase the friction of the clamping operation and prevent slipping.

[0025] (7) The inner cover has a simple structure, cheap materials and low production cost. BRIEF DESCRIPTION OF THE DRAWINGS
