It is provided with external screw thread, is connected through a screw thread the top cup 110, connector 130 and bottom 120 releasable connections of cup, for another example, Ke Yitong
It crosses card slot connection or card slot and the mode of threaded connection will be by the top cup 110, connector 130 and bottom 120 releasable connection of cup.
Preferably, the top cup 110 has scale, facilitates viewing to measure volume of the body of paste beyond bottom 120 volumes of cup, prevents
It is excessive only to measure body of paste, causes to waste, further, it is preferable that the top cup 110 is transparent material.
Fig. 2 is the schematic diagram of a preferred embodiment of container of the present invention, and as described in Figure 2, the container 100 wraps
It includes:
Bottom cup 120, has an open end, and the open end has outer 121；
Cup 110 is pushed up, there are two open ends for tool；
Connector 130, one end are detachably connected with the top cup 110, and the other end is provided with interior along 131, pass through bottom cup 120
Outer 121 be placed on described interior along 131, the connector 130 is connect with bottom cup 120, that is to say, that the bottom
Cup 120 outers 121 outer diameter no more than the connector 130 it is interior along 131 outer diameter (internal diameter of connector 130) and be greater than institute
State it is interior along 131 internal diameter.
In order to guarantee the tight type of connection, it is preferable that the top cup 110 is threadedly coupled with the connector 130, for example,
The connector 130 is provided with internal screw thread, and one end of the top cup 110 is provided with external screw thread, is connected through a screw thread the top

Preferably, the internal diameter of the top cup 110 prevents top cup from moving 110 from bottom cup no more than the internal diameter of the bottom cup 120
When being removed on 120, from top 110 over flood paste of cup, the outer surface of contamination bottom cup 120, it is further preferred that the top cup
110 and bottom cup 120 in internal diameter and outer diameter cylindrical shape all the same.
Said vesse 100 is convenient for disassembly and assembly, and after excluding the bubble in container 100 in paste, removes top cup 110,
Connector 130 falls off from bottom cup 120 automatically, pushes up the removal of cup 110 and connector 130, not will cause the movement of bottom cup 120, prevents
Only bubble is again introduced into body of paste, increases the accuracy of body of paste volume.
Fig. 3 is the flow chart of body of paste density measuring method of the present invention, as shown in figure 3, the body of paste density measure side
Method includes:
Firstly, in step s310, the quality of bottom cup 120 is weighed, for example, adopting the quality for weighing bottom cup 120 in the balance；
In step s 320, the volume of measurement bottom cup 120, for example, using ultrasound volume measuring instrument or the method for titration
Measure the volume of bottom cup；
In step S330, container 100 is assembled, is measured using container 100 after assembling and is greater than bottom 120 volumes of cup
Container 100 equipped with paste is put into vacuum oven 200 by paste；
In step S340, the temperature in vacuum oven 200 is heated to prescribed limit, while using vacuum degree by small
200 internal classification of vacuum oven is vacuumized to big mode, it is preferable that, will when being vacuumized to vacuum oven classification
The vacuum degree of every level-one maintains the predetermined time, wherein the prescribed limit and predetermined time set according to paste material；
In step S350, vacuum degree reaches specified value in vacuum oven 200, maintains the predetermined time until the paste
There is no bubble, the specified value and the predetermined times in object sets according to paste material；
In step S360, stop heating, and lose heart to vacuum oven 200, so that reaching normal in vacuum oven 200
Mild normal pressure；
In step S370, top cup 110 is removed, removal overflows the paste of bottom cup 120, smears 120 rim of a cup of tumbler；
In step S380, the quality of the above-mentioned bottom cup 120 for filling with paste is weighed, the quality is subtracted into sky bottom cup
120 quality obtains the quality of paste；
In step S390, according to the quality and volume of paste, the density of paste is obtained.
Above-mentioned body of paste density measuring method to the container 100 for filling paste while being carried out by vacuum oven 200
It vacuumizes and heats, the bubble in paste could be excluded, because paste viscosity is larger, directlys adopt heating or vacuumize
Method cannot exclude the bubble in paste.
In addition, measuring paste using integral type volume, after heating and vacuumizing, original body of paste volume can become
It is small, paste surface irregularity, the exact volume for the paste that can not be learnt, body of paste density measuring method of the present invention
Body of paste more than bottom 120 volumes of cup is measured using Split container 100, guarantees the paste table after heating and vacuumizing
Face is higher than bottom cup rim of a cup, by smearing tumbler rim of a cup, it is ensured that the volume of paste is bottom cup volume.
Furthermore the method that body of paste density measurement method of the present invention is vacuumized using classification prevents pressure moment from becoming
It is small, cause paste to splash out.
Preferably, the 1/4-3/4 for being greater than bottom 120 volumes of cup and being no more than top 110 volume of cup is measured using container 100, into
One step preferably, 2/3 paste for being greater than bottom 120 volumes of cup and being no more than top 110 volume of cup is measured using container 100, because
For paste object amount is too many, and paste easily splashes out container 100 during bubble removing；Paste object amount is very little, cannot ensure paste
After bubble removing, the lowest part of the male and fomale(M&F) of the paste in container 100 is higher by bottom 120 top edges of cup, it is ensured that in bottom cup 120
Paste be paste after bubble removing.
In one embodiment of the invention, using paste density measurement device and method of the present invention to ointment into
Line density test the step of include:
Bottom 120 volumes of cup are titrated, obtain the volume of cup 120 on earth to get to the body of paste for filling with bottom cup 120
Volume；
Ointment is measured with the container 100 after assembling, the container 100 equipped with ointment is put into vacuum oven 200；
Temperature in vacuum oven is gradually heated to 60 DEG C~80 DEG C, by the vacuum degree in vacuum oven from-
0.02MPa, -0.04MPa, -0.06MPa classification vacuumize, and the vacuum degree of every level-one maintains about 5~10min；Vacuum degree is adjusted again
About 2~3h is vacuumized to -0.1MPa, and is lost heart during this period every about 3min once, until bubble-free (can in ointment in container
To control the observation of drying box transparent window by intelligence)；
Take out container 100, be put into vacuum oven after being cooled to environment temperature carefully remove top cup 110 (have a small amount of oil
Cream adheres on the wall)；
Bottom rim of a cup is smoothed out with sheet glass or plastic sheet, and overflows the ointment of bottom cup with clean clean article removal；
Weigh the mass M for measuring the above-mentioned bottom cup for filling with ointment in the balanceBrimmer, it is described fill with ointment bottom cup quality subtract
The quality of empty bottom cup, obtains the mass M of the ointment, M=MBrimmer-MEmpty cup, wherein MEmpty cupFor the quality of bottom cup；
According to density calculation formulaObtain surveyed ointment density.
Fig. 4 gives ointment and the comparison diagram before bubble and being discharged after bubble is discharged, as shown in figure 4, paste of the present invention
Volume density measurement method has been effectively discharged out the bubble in ointment, ensure that the accuracy of ointment cubing, to ensure that
The accuracy of ointment density measure.
Although content disclosed above shows exemplary embodiment of the present invention, it should be noted that without departing substantially from power
Under the premise of benefit requires the range limited, it may be many modifications and modify.According to the side of inventive embodiments described herein
Function, step and/or the movement of method claim are not required to the execution of any particular order.In addition, although element of the invention can
It is unless explicitly limited individual element it is also contemplated that having multiple elements to be described or be required in the form of individual.
