Description

Technical Field

[0001] The utility model relates to the field of test instruments, in particular to a reagent bottle. Background Art

[0002] Reagent bottles are widely used in biology, chemistry and other fields. Most of the reagent bottles currently on the market, especially those used to collect and store dental plaque and gastric mucosa samples, have a conical bottom structure. This design is prone to substrate accumulation when drying the substrate, and it cannot be dried thoroughly, which may lead to false positive results of the sample. In addition, the conical bottom of the bottle also makes the substrate flattening effect poor, affecting the observation and interpretation of the sample. Utility Model Content

[0003] The utility model aims to provide a reagent bottle, which can improve the drying effect, speed up the drying efficiency, avoid substrate accumulation and facilitate observation and interpretation.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A reagent bottle comprises a longitudinally extending bottle body, wherein the axial cross section of the bottom of the bottle body is an arc shape with an opening upward, the side wall of the bottle body extends downward along its axial direction to form an annular base, and the horizontal height of the lowest point of the bottom wall of the bottle body is higher than the horizontal height of the lowest point of the annular base.

[0006] Compared with the prior art, the advantages of the utility model are:

[0007] 1. The arc-shaped structure design at the bottom of the bottle helps to evenly spread and dry the substrate, thereby avoiding false positives due to insufficient drying of the sample;

[0008] 2. Through the window set on the annular base, the operator can directly observe the substrate condition in the bottle through the window, so as to facilitate the result interpretation, and the drying heat source can directly dry the bottom of the bottle through the window, thereby improving the drying efficiency;

[0009] 3. The use of highly transparent polystyrene material improves the transparency of the bottle, making it easier to observe the sample in the bottle and to interpret the results. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The content of the utility model is described in detail below in conjunction with the accompanying drawings and embodiments of the specification, but the protection content of the utility model is not limited to the following:

[0017] Embodiment 1:

[0018] like Figures 1 to 4 As shown, it is a schematic structural diagram of Example 1 of a reagent bottle of the utility model, which includes a longitudinally extending bottle body 1, the axial cross-section of the bottom of the bottle body 1 is an arc shape with an opening upward, the side wall of the bottle body 1 extends downward along its axial direction to form an annular base 2, and the horizontal height of the lowest point of the bottom wall of the bottle body 1 is higher than the horizontal height of the lowest point of the annular base 2.

[0019] The annular base 2 is provided with a viewing window 3 for observing the bottom condition of the bottle body 1 .

[0020] The viewing window 3 is a notch extending upward from the lower end of the annular base 2 , and the horizontal height of the highest point of the notch is higher than the horizontal height of the lowest point of the bottom wall of the bottle body 1 .

[0021] The viewing window 3 is in an inverted U shape.

[0022] The windows 3 are arranged in two groups facing each other, and the windows 3 make the air around the bottom of the bottle body 1 flow more smoothly, which is helpful for uniform drying of the substrate and also makes it easy for the operator to observe the state of the substrate.

[0023] The bottle body 1 is made of transparent material.

[0024] The bottle body 1 is made of highly transparent polystyrene to enhance the perspective of the bottle body 1, making it easier to observe the sample in the bottle and to interpret the results.

[0025] The material of the annular base 2 is also transparent.

[0026] The side wall of the bottle body 1 is provided with scale lines. Since it is a conventional technique in the art to provide scale lines on the surface of a reagent bottle, the drawings of the present utility model do not show scale lines on the surface of the bottle body 1.

[0027] The upper part of the bottle body 1 is provided with a bottle cap 4 which is detachably connected thereto.

[0028] The upper portion of the bottle body 1 is provided with an external thread, and the bottle cap 4 is provided with an internal thread, and the two are threadedly connected to achieve disassembly and assembly.

[0029] The inner wall surface of the bottle cap 4 is provided with an elastic gasket which is sealed with the bottle body 1 to ensure the sealing between the bottle body 1 and the bottle cap 4 .

[0030] An annular convex edge 5 extends outward from the upper portion of the bottle body 1 , and the annular convex edge 5 is used for limiting the position and supporting the bottle cap 4 .

[0031] The inner diameter of the bottom of the bottle body 1 gradually decreases from top to bottom, and the axial cross-section of the bottom is an arc shape with an opening facing upward.

[0032] The height of the bottle body 1 is 25 to 30 mm.

[0033] The distance between the lowest point of the annular base 2 and the lowest point of the bottom wall of the bottle body 1 is 1-3 mm.

[0034] The outer diameter of the bottle body 1 is 8 to 12 mm.

[0035] The diameter of the bottle body 1 is 6 to 10 mm.

[0036] The bottle body 1, the annular base 2 and the annular convex edge 5 are integrally formed.

[0037] The outer wall of the bottle cap 4 is provided with anti-skid patterns for increasing friction.

[0038] Embodiment 2:

[0039] like Figure 5 As shown, it is a schematic diagram of the structure of Example 2 of a reagent bottle of the utility model. The basic structure of Example 2 is generally similar to that of Example 1. The difference between Example 2 and Example 1 is that the window 3 is a rectangular window opened on the side wall of the annular base 2, and the horizontal height of the highest point of the rectangular window is higher than the horizontal height of the lowest point of the bottom wall of the bottle body 1.
