Technical Field
The utility model relates to a sealed technical field of tubular container especially relates to a promotion formula tube cap.
Background
In scientific research or production work in biological, medical and clinical fields, aseptic operation is one of important basic operations. Test tube containers used in aseptic operations often need to be protected and sealed with caps, stoppers, or sterile cloths, isolated from the outside environment, to prevent contamination by external microorganisms. A drawback of the caps, stoppers or sterile cloths conventionally used is that the tightness may be insufficient and leakage may easily occur during transfer or transportation of the test tube containers. Meanwhile, two-handed operation is generally required in opening and closing the cap, stopper or sterile cloth of the test tube, which increases the complexity of the operation and the risk of contamination, while reducing the working efficiency.
Chinese patent CN 203753598U discloses a wrenching type container cover and a container using the same. The wrenching type container cover at least comprises an upper cover and a lower cover, and the one-hand operation of opening and closing the container cover is realized by wrenching a wrenching part of a flat protrusion which extends upwards on the surface of the upper cover. Chinese patent CN 204675050U discloses a push type container cover, which can be opened or closed by pushing a tube cover with one hand.
However, the above container lids all have drawbacks.
