Description

A spill-proof experimental threaded bottle

Technical field

The utility model relates to the technical field of laboratory containers, in particular to a laboratory threaded bottle that prevents spillage.

Background technique

Glass reagent bottles are containers used to hold reagents and solvents in laboratories, laboratories, hospitals, schools and other scenes. Reagent bottles are a general term, and there are many classifications in practical applications. Since many reagents or medicines will undergo various reactions under light, in order to store or contain them better, almost all types of reagent bottles are available in transparent and dark brown colors. Brown reagent bottles are specially used to contain light-resistant reagent bottles. Reagents that react and decompose; for bottle stoppers, they can be divided into ground mouth, non-grinding mouth, threaded cap, and rubber stopper. For general organic solvents or reagents, ground glass bottle stoppers are selected (two-way grinding mouth prevents moisture absorption); non-grinding The plug has limited sealing properties and is mainly used to hold reagents for immediate use; the threaded cap has good sealing properties; rubber plugs are often used for alkaline reagents.

In the biological field, it is often necessary to configure a culture medium to supply the growth and reproduction of microorganisms, plants and animal tissues. The culture medium is a nutrient matrix composed of different nutrients, generally containing water, nitrogen sources, carbon sources, growth factors, etc., when used It needs to undergo high-temperature sterilization. Because it contains various nutrients, it is easy to be contaminated and spoiled, so it needs to be prepared and used immediately. Glass reagent bottles (threaded caps) with good sealing properties need to be used during configuration. After the configuration is completed, they are sterilized at high temperature. Antibiotics are added to the bottles in a clean bench and placed in separate bottles. Currently, in major laboratories, on the basis of process optimization, liquid leakage often occurs when using transparent glass bottles to dispense liquids. This not only causes a certain loss of reagents, but also requires cleaning in a super-clean room after the experiment. The solidified culture medium spilled on the work surface caused inconvenience to the experimental operation. Therefore, there is an urgent need for a glass bottle mouth with threaded cap that is optimized on the basis of ensuring aseptic operation during dispensing to improve the situation of liquid leakage and unstable water discharge.

Figures 1, 2, 3 and 4 show a specific embodiment of a spill-proof experimental threaded bottle of the present invention. In this embodiment, the spill-proof experimental threaded bottle specifically includes: Bottle body 1, bottle body 1 is made of glass, and the bottle cap is made of polypropylene (PP). The bottle body 1 is provided with a bottle mouth 2, the outer circumferential surface of the bottle mouth 2 is provided with external threads 3, and the inner circumferential surface of the bottle cap is provided with internal threads. The bottle cap can be tightened on the bottle mouth 2 through the cooperation of the internal and external threads.

A plurality of guide walls 4 are provided on the inner wall of the bottle mouth 2. In this embodiment, four guide walls 4 are provided. The guide walls 4 are distributed along the circumferential direction of the bottle mouth 2. Two adjacent guide walls 4 are arranged on the inner wall of the bottle mouth 2. There is a confluence channel 6 for the liquid in the bottle to flow out between the flow walls 4. The inner wall of the bottle mouth 2 constitutes the bottom 7 of the confluence channel 6, and the outer surface 5 of the guide wall constitutes the channel wall of the confluence channel 6. The guide wall The outer surface 5 of the bottle mouth 2 is smooth. In the cross section of the bottle mouth 2, the outer surface 5 of the guide wall constitutes the chord of the inner circle of the bottle mouth 2. The confluence channel 6 is provided with a trumpet-shaped confluence opening 8 at one end facing the bottle body 1 .

Screw-thread bottles are available in five capacity specifications: 50 mL, 100 mL, 250 mL, 500 mL and 1000 mL. The inner diameter of the 50 mL threaded bottle is 1.8 cm, and the other inner diameters are 3 cm. There is no obvious change in appearance. By increasing the thickness of the inner wall of the bottle mouth, a simple drainage channel is designed, which can still maintain a stable output of water flow even when the bottle is large and difficult to handle and difficult to operate in a clean workbench. Reduce water flow width. The shape of the confluence trough 6 is approximately an inverted trapezoid when viewed inward from the bottle mouth. The width of the bottom 7 of the confluence trough 6 is 1/4-1/3 of the diameter of the bottle mouth 2. Taking the inner diameter of 3 cm as an example, the bottom of the trapezoid is 1 cm, the inverted trapezoidal design concentrates the water flow and makes it more stable. The formed confluence groove will not have any impact on the sealing of the bottle itself, and the depth of the groove is more conducive to drainage.

The anti-spill experimental threaded bottle provided by this utility model is designed with a simple drainage channel by increasing the thickness of the inner wall of the bottle mouth. Even when the bottle is large and difficult to handle and difficult to operate on a clean workbench during dispensing, It can still maintain stable output of water flow and reduce the width of water flow.
