Description

Triangular flask

Technical Field

The application relates to the cell culture device field, especially relates to a triangular flask.

Background

In recent decades, due to the rapid development of the biological product industry, the method of directly obtaining biological products from animal tissues has been far from meeting the market demand, animal cells are cultured in vitro in large scale by using a cell culture device to obtain certain protein, monoclonal antibody, interferon and virus vaccine products, disposable plastic triangular flasks have the characteristics of high transparency, firmness and stability, large capacity and easy fixation on a shaking bed for dynamic culture operation, and are widely applied in large scale bacterial culture, industrial fermentation, suspension cell culture and other aspects, however, the triangular flasks have extremely high operation frequency in a culture period, and need to be opened or closed frequently, the threads of the conventional bottle caps are fine threads with multiple layers, and the caps need to be opened or closed by turning knobs for multiple turns, so the operation is very inconvenient, and two hands are needed for operation, when other objects are held in one hand, it is difficult to open or close the lid with one hand.

SUMMERY OF THE UTILITY MODEL

An object of this application is to provide a triangular flask, solve because the uncap of triangular flask or close the lid need the many rings of knob bottle lid, cause the inconvenient and difficult technical problem of one-hand operation of operation.

In view of the above, the present application provides a triangular flask, comprising: a bottle cap and a bottle body;

the bottle cap is provided with a first double-thread;

the bottle body is provided with a second double-thread matched with the first double-thread;

the first double-thread and the second double-thread are both thick threads with the width of 5 mm.

Further, each thread of the first double thread encircles 1/4 circles of the inner side wall of the bottle cap, and each thread of the second double thread encircles 1/4 circles of the outer side wall of the bottle neck of the bottle body.

Further, the bottom of the bottle body is inwards concave.

Furthermore, the outer part of the bottle cap is provided with a longitudinal protruding strip.

Furthermore, the top of the bottle cap is provided with an air hole.

Furthermore, the air holes are wrapped with air permeable filter membranes.

Furthermore, the starting end of the second double-thread is triangular, and the tail end of the second double-thread is in a slope shape.

Compared with the prior art, the embodiment of the application has the advantages that:

the application provides a triangular flask, includes: a bottle cap and a bottle body; the bottle cap is provided with a first double-thread; the bottle body is provided with a second double-thread matched with the first double-thread; the first double threads and the second double threads are both coarse threads with the width of 5 mm. The utility model provides a triangular flask, be 5 mm's first double-thread through being provided with the width on the bottle lid, and set up on the body and be 5 mm's second double-thread with first double-thread matched with width, thereby reached and rotated 90 degrees lids of screwing of optional position, reduce the number of turns of spiral cover, and can singlehandedly accomplish the technological effect that the spiral cover becomes the operation, solved because the uncapping of triangular flask or closing the lid need the knob bottle lid multiturn, cause the inconvenient technical problem that just is difficult to the one-handed operation of operation.
