Description

Tissue culture bottle

Technical Field

The utility model relates to a microbial cultivation field, concretely relates to group banks up bottle with earth.

Background

The tissue culture bottle is a vessel for culturing strains, and the pollution of other strains in the culture process can seriously affect the strain culture effect. The tissue culture bottle in the prior art usually adopts a cylindrical bottle mouth, the outer side of the bottle mouth is provided with an external thread, and the bottle caps with the internal threads are matched with each other, so that the tissue culture bottle is sealed. In the process of pouring the culture solution in the tissue culture bottle, a small amount of culture solution is easy to remain in the thread gap between the bottle cap and the bottle mouth, so that sundry bacteria are bred in the gap, and further, the strains cultured in the tissue culture bottle are polluted.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the above-mentioned technique not enough, provide a group banks up bottle with earth, solve among the prior art technical problem that the thread gap easily breeds miscellaneous fungus and influence the bacterial cultivation effect.

In order to achieve the technical purpose, the technical proposal of the utility model comprises:

the bottle body part is conical in the outline;

the bottle mouth part is square and is arranged at the conical top;

the bottle cap is square, is covered on the bottle mouth part in a clamping connection mode, and the outer wall of the bottle mouth is a smooth surface.

Compared with the prior art, the beneficial effects of the utility model include: the body portion is the taper, and the group that compares in the straight tube-shape banks up the bottle with earth can assemble liquid to bottleneck portion flow in-process in empting the in-process, and is controlled more easily. Meanwhile, the square bottle mouth part is matched with the square bottle cap, and the clamping type matching method is used for replacing the original threaded matching of the bottle cap and the bottle mouth part. The fitting surface of bottle lid and bottleneck is the plain noodles, consequently can avoid empting in-process culture solution and remain in the gap of screw thread, and then has avoided the screw thread gap to breed miscellaneous fungus and influence the cultivation effect.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is 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 illustrative of the invention and are not intended to limit the invention.

The utility model provides a group banks up bottle with earth, including body 100, bottleneck portion 200, bottle lid 300 and accepting 400.

The bottle body 100 has a tapered profile, and has a truncated pyramid with four square corners, and in addition, rounded corners are provided on the bottom edge and the sidewall edge to avoid stress concentration. It should be noted that the bottle portion 100 is made of transparent material, and the sidewall of the bottle portion 100 is provided with a scale for weighing the liquid inside the bottle portion 100.

The bottle mouth 200 is square, and the outer wall of the bottle mouth is smooth and is arranged at the cone top. Meanwhile, a clamping groove 210 is formed on the square side line of the end face of the bottle mouth part 200.

The bottle cap 300 is square, and the cross section of the bottle cap 300 is inverted U-shaped, so that the bottle cap 300 is covered on the bottle mouth portion 200, and the square structure on the inner side of the bottle cap 300 is matched with the outer contour of the square bottle mouth portion 200. So that the bottle cap 300 is sleeved on the bottle mouth and clamped and fixed. Meanwhile, in order to meet the requirement of culturing strains, a breathable film 310 is additionally arranged on the top of the bottle cap 300.

It should be noted that the sealing property of the bottle cap 300 covering the bottle opening 200 should be ensured to ensure that the bacteria cultured in the bottle are contaminated by the bacteria in the external environment, so as to improve the manufacturing precision of the bottle cap 300 and the bottle opening 200 and to make the matching surfaces of the two closely fit. However, although the method can meet the sealing requirement, the manufacturing cost of the tissue culture bottle is greatly increased correspondingly. It is preferable to embed a rubber gasket inside the bottle cap 300 to satisfy the sealing requirement.

Containing part 400 includes containing basket 410 and splice bar 420, and containing basket 410 places in bottle portion 100, and containing basket upper limb upwards extends simultaneously and forms four splice bars 420, and the free end of splice bar 420 forms joint end 421 simultaneously, and joint end 421 cooperates with joint groove 210 and realizes containing part 400 fixed. In the actual use process, the material holding basket 410 holds the substrate to which the strains grow, and then the substrate is soaked in the culture solution in the bottle portion 100, and the material holding basket 410 can be adjusted to a certain degree according to the needs of the strains to be cultured, for example, a screen structure or a grating structure is adopted. The material containing part 400 is used for taking and placing experimental strains from the tissue culture bottle conveniently. Meanwhile, when the culture solution is poured, one corner of the bottle mouth part 200 can be selected for pouring due to the square bottle mouth part 200, and the situation that the liquid flows out of the clamping groove 210 is not needed to be worried about.

The utility model provides a group banks up bottle with earth, body portion 200 are the taper, compare in the group of the straight tube-shape group banks up the bottle with earth and can assemble liquid to bottleneck portion 200 flow in-process empting the in-process, controls the flow of empting more easily. Meanwhile, the square bottle mouth part 200 is matched with the square bottle cap 300, and the clamping type matching method is used for replacing the thread matching of the original bottle cap 300 and the bottle mouth part 200. Thereby avoided the thread gap to remain the culture solution and lead to miscellaneous fungus to breed, and then avoided miscellaneous fungus to pollute the cultivation bacterial of group banks up the interior of bottle with earth, influences the cultivation effect.

The above description of the present invention does not limit the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the scope of the claims of the present invention.
