As shown in Figure 1, the distance in the first opening 22 to first face 111 is greater than second face 112 described in
The distance in the first face 111.In this way, the bottle stopper ontology 1 is all placed in the cavity 21, so that the capacity bottle stopper 10
When just putting on the table, second face 112 can be avoided to be contacted with desktop, so as to avoid the pollutant on desktop to institute
Pollution caused by bottle stopper ontology 1 is stated, the experimental result of standard liquid is further ensured.
However, in other embodiments, first opening 22 can also be concordant with second face 112, at this time in order to
10 side of capacity bottle stopper can be put to pollution caused by second face 112, make the sleeve 2 by desktop when avoiding just putting
It is contacted with desktop.
As shown in Figures 1 to 4, the other end of the sleeve 2 is formed with the second opening 23, and first face 111 is connected to
At second opening 23, so that second opening 23 is closed in first face 111.This way it is possible to avoid dust and the external world
Pollutant enters the cavity 21 by second opening 23, and then ensure that the cleaning of the bottle stopper ontology 1.
As shown in Figure 1 to Figure 3, the capacity bottle stopper 10 further includes hand-held part 3, and the hand-held part 3 is connected to described first
On face 111.Being provided with for the hand-held part 3 is conducive to operation.The bottle stopper ontology 1, the sleeve 2 and the hand-held part 3 at this time
It is integrally formed.
As shown in figure 4, the hand-held part 3 may be omitted with, at this point, operator may not necessarily also contact the bottle stopper sheet
Body 1, it is only necessary to which holding the sleeve 2 can be completed operation.At this point, the bottle stopper ontology 1 and the sleeve 2 are integrally formed.
As shown in Figures 5 and 6, the capacity bottle stopper 10 further includes flange 4, in the axial direction of the capacity bottle stopper 10, institute
Stating flange 4 has the third face 41 being oppositely arranged and fourth face 42, and the third face 41 is connect with first face 111, described
Fourth face 42 is connected to close second opening 23 at second opening 23, and the area in the third face 41 is greater than described
The area in the first face 111.Closing second opening 23 can be to avoid dust and environmental contaminants by second opening 23
Into the cavity 21, and then it ensure that the cleaning of the bottle stopper ontology 1.
In the present embodiment, the bottle stopper ontology 1, the sleeve 2 and the flange 4 are integrally formed.
It is also possible that the hand-held part 3 is set on the fourth face 42, the bottle stopper ontology 1, the sleeve 2, the hand
It holds portion 3 and the flange 4 is integrally formed.
In embodiment not shown, first face 111 completely cuts off second opening 23 and the gap 211.In this way,
First face 111 is connected to the inner wall of the cavity 21 between first opening 22 and second opening 23
On, equally the cavity 21 can also be entered by second opening 23 to avoid dust and environmental contaminants.
