Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to experimental vessel field, concretely is a novel reagent bottle for laboratory. BACKGROUND
[0002] In the daily operation of the laboratory, the reagent bottle is an indispensable experimental instrument, which undertakes the key task of containing and storing various chemical reagents. Whether it is basic scientific research or application type experimental analysis, the use frequency of the reagent bottle is extremely high.
[0003] However, the current reagent bottle commonly used in the laboratory has a more prominent problem in the actual use process: when the reagent pouring operation is carried out, the reagent is often attached to the bottle wall, that is, the so-called "hanging cup" phenomenon. This seemingly insignificant problem can cause a series of adverse consequences. On the one hand, the hanging cup causes the reagent to be unable to be completely used, resulting in waste of the reagent. For some special reagents that are expensive and difficult to prepare, even a small amount of waste will accumulate over a long period of time and will bring a not inconsiderable economic burden to the laboratory. On the other hand, if the residual reagent is not cleaned in time, it may dry and crystallize on the outer wall of the reagent bottle, affecting the use of the subsequent reagent, and even contaminating the subsequent reagent, thereby interfering with the accuracy of the experimental results. SUMMARY
[0004] In view of the above technical problems, the utility model provides the following technical scheme:

[0011] Further, the upper part of the bottle body is tapered, and the bottom is narrowed, so as to increase stability.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0024] Example 1
[0025] like Figures 1-3 As shown, a novel reagent bottle for laboratory use includes a bottle body 101 and a cap assembly 102. The bottle body 101 is made of borosilicate glass, tapering at the top and narrowing at the bottom to form a smaller diameter base, enhancing stability during placement. The outer wall of the bottle opening has external threads that mate with the internal threads of the outer cap 205 of the cap assembly 102. A silicone sealing gasket is provided inside the outer cap 205 at the contact point with the bottle opening to ensure reagent sealing; the silicone sealing gasket has a hardness of 50 Shore A. The inner cap 204 is made of polypropylene, and the outer cap 205 is made of polyethylene or polypropylene. The sealing gasket is made of polytetrafluoroethylene or silicone rubber. The inner cap 204 is connected to the upper part of the outer cap 205 via external threads and has a spiral flow channel 201 inside, with a depth of 0.5 mm and a thickness of 0.1 mm, extending to the flow port 202. The guide port 202 extends outward by 1.5 mm and is tilted at a 15° angle to guide the reagent outward in a directional manner and reduce residue at the bottle mouth.
[0026] Example 2
[0027] The technical features in this embodiment are basically the same as those in Embodiment 1. The same technical features and solutions will not be repeated here. Only the differences between Embodiment 2 and Embodiment 1 will be described here.
[0028] like Figures 5-6 As shown, in this embodiment, an anti-slip part 203 is provided in the middle of the outer wall of the bottle body 101. The anti-slip part 203 adopts a short diagonal texture design, the groove depth is 0.4 mm, and the surface is integrally molded with the bottle body through injection molding, conforming to the curvature of the experimenter's palm. This design can enhance the friction when gripping and prevent the reagent bottle from slipping. In addition, the anti-slip part 203 can also be replaced with a granular groove structure, such as... Figure 7Particle diameter 0.5mm, depth 0.3mm, suitable for different experimental habits of experimenters.
[0029] Embodiment 3
[0030] In this embodiment, in order to distinguish different reagent bottles, an identification label is pasted on the outer wall of the bottle body 101. The identification label 103 is composed of a base paper 206 and an adsorbing film 207. The base paper 206 has a thickness of 0.2mm and is made of waterproof kraft paper. The adsorbing film 207 is a PET electrostatic adsorbing film with a thickness of 0.12mm and is adsorbed on the middle part of the bottle body 101 through electrostatic adsorption. The label content can be handwritten or printed, and when replaced, the old label can be directly peeled off and a new label can be adsorbed to realize repeated use. This design avoids the problem of residual glue stains after tearing off the traditional adhesive label, thereby reducing the maintenance cost.
[0031] As shown in Figures 4-6 , the identification label 103 is adsorbed on the middle part of the bottle body, and the edge of the identification label 103 is slightly rolled to facilitate the user to peel it off. The technology adopted by the adsorbing film 207 is mainly based on the principle of electrostatic adsorption. The existing electrostatic adsorption is easy to paste, can be recycled, is corrosion-resistant (solvent type), and can be written with a marker pen. The water-based pen can be cleaned with water or alcohol, and the oil-based pen can be cleaned with acetone reagent. In the current environment of reducing cost and increasing efficiency, the use of this material can not only prolong the placement period of the label, but also reduce the cost of the label. The electrostatic adsorption is provided with a plurality of identification columns. The left side is the reagent name, chemical formula, preparation concentration, preparer, preparation date, and expiration date. These fields can be handwritten to write information. The right side is a hazard level icon and a bar code. The top of the label is provided with a color band (red represents flammable, yellow represents corrosive, etc.). The format of the identification label 103 is realized through UV printing technology. The color area can use fluorescent pigments to improve the recognition degree.
[0032] Embodiment 4
[0033] As shown in , in this embodiment, the flow guide groove 201 is used in cooperation with the flow guide port 202. The spiral structure of the flow guide groove 201 can guide the reagent to flow along the groove. The flow guide groove 201 is processed by CNC to reduce the contact area with the bottle opening. The flow guide port is an extension of the outer part of the inner cover 204, and the inclination angle is 15°, which further concentrates the reagent to the flow guide port 202. The actual test shows that this design can reduce the reagent residue by about 60%. In addition, the material of the bottle body 101 can be replaced by polypropylene plastic which is resistant to chemical corrosion, and is suitable for containing organic solvents.
[0034] In use, first take off the original bottle cap of the reagent bottle, screw the outer cover of the bottle cap assembly to the bottle mouth of the bottle body through the thread, ensure that the silica gel sealing washer inside the outer cover fully contacts with the bottle mouth to realize sealing, prevent reagent leakage or volatilization. Then, screw the inner cover into the threaded interface in the upper part of the outer cover through the outer thread thereof until completely fixed. When pouring reagent, the operator needs to tightly hold the anti-skid part of the outer wall of the bottle body with the palm, uses the short oblique line or granular groove texture to enhance the friction force, prevents slipping. Slowly tilt the bottle body, the reagent flows along the spiral flow guide groove inside the inner cover under the action of gravity, and flows out through the flow guide port. The inclined angle design of the flow guide port further guides the reagent to accurately transfer to the target container or instrument, significantly reduces the bottle mouth residue. For high viscosity or volatile reagent, the flow efficiency can be optimized by adjusting the pouring angle and speed. After use, the electrostatic adsorption type identification label can be removed to update the information or clean the bottle body, ensure the convenience and safety of next use.
