Buckle cap culture tube

Abstract

The invention discloses a button-cap type culture tube, which is composed of a tube body and a tube cover, and is characterized in that: an annular protrusion of the tube body is processed on the outer wall of the top end of the tube body, and a concave inner clip is arranged in the middle of the top of the tube cover The outer wall of the inner plug with a cross-section of "W" shape is smooth and can closely match the inner wall of the tube. The upper end of the outer wall of the inner plug is processed with a tube cover ring-shaped protrusion that can squeeze the inner wall of the tube. On the top of the tube cover The bottom of the annular edge is provided with the bottom surface of the annular edge of the pipe cover which coincides with the top surface of the pipe body. The inner wall and the outer wall of the pipe cover are respectively processed with a plurality of inner vertical reinforcing ribs and outer vertical reinforcing ribs arranged at even intervals, and an annular protrusion of the pipe cover is arranged on the outer wall of the bottom end of the pipe cover. The invention has the advantages of not only realizing the sealing fit between the tube body and the tube cover, but also reducing the height of the tube body, saving raw materials, reducing product volume, preventing liquid leakage, ensuring that the tube cover will not be deflected after being closed, and that the tube cover will not be deflected when it is opened. It will fall off directly, has the advantages of simple structure and convenient use.

Description

technical field [0001] The invention relates to a medical device, in particular to a button-cap culture tube. Background technique [0002] Buckle cap culture tube is a commonly used medical device, made of transparent polymer material polypropylene (PP), mainly used to hold a certain volume of liquid, widely used in tissue culture, bacteriology, clinical, scientific research and other fields . Most of the culture tubes currently on the market are composed of a tube body and a tube cover that are sealed and matched by threads. Due to the thread design, the height of the tube body is high, which wastes raw materials on the one hand and increases the volume of the product on the other hand. Contents of the invention [0003] The purpose of the present invention is to provide a buckle-cap culture tube that can better realize the sealing fit between the tube body and the tube cover, reduce the height of the tube body, save raw materials, reduce product volume, simple structur...

AI Technical Summary

Problems solved by technology

Most of the culture tubes currently on the market are composed of a tube body and a tube cover that are sealed and matched by threads. Due to the thread design, the height of the tube body is relatively high. On the one hand, raw materials are wasted, and on the other hand, the volume of the product is increased.
