Fig. 7 is the explanatory diagram of container cover 13V, and Fig. 7 (a) is the top view of container cover 13V, and Fig. 7 (b) is container cover 13V
Upward view.
As illustrated, the peristome that container cover 13V is formed as through hole 13a is rotational symmetric configuration in a top view.
The peristome of first through hole TH1 is the first peristome TH1x, in a top view along being set in first connecting portion
The first imaginary circle IC1 configuration of 131A.Additionally, the peristome of the second through hole TH2 is the second peristome TH2x, it is set in second even
Socket part 131B and along the circle with the first imaginary circle IC1 concentric be second imaginary circle IC2 configuration.Additionally, in a top view, with
The center C of heart circle is overlapped with the central shaft CA of fitting portion 132.

Second peristome TH2x will be aggregated into multigroup unit α, can suitably adjust configuration as needed.And then, in the appearance of this variation
In device lid, it is also possible to each unit α need not be collected in the case that there are multiple second peristome TH2x.
Fig. 9 is the explanatory diagram of the effect for said vesse lid 13V is described, is the figure of top view container cover 13V.Fig. 9
A () shows that through hole is along the circumferential direction configured to existing container cover 13Z of string, Fig. 9 (b) shows the container of the present application
Lid 13V.
As described above, container cover 13V spiral shell inherently carries out the fixing fixture 17 of air-tightness to pipe arrangement.Thus, for example, dimension
When the pipe arrangement of dirty being changed in shield upkeep operation, or need when suspecting that air-tightness is impaired on the position of fixture 17
When fixture 17 is carried out increase with packing process, need to carry out the rotating operation to fixture 17 using instrument.
But, in the case of container cover 13Z shown in Fig. 9 (a), it is arranged with multiple fixtures 17, institute in a circumferential direction
To be not inserted into the space of instrument.Additionally, when using instrument T rotational fixture 17, instrument T occurs to do with the fixture 17 of surrounding
Disturb, it is possible that fixture 17 cannot be taken off.
And then, if arranging gap in order to be able to take off fixture 17 between fixture 17, then need to increase container cover
The volume of 13Z itself, or reduce the quantity of through hole.
On the other hand, as shown in Fig. 9 (b), in container cover 13V, multiple through holes are separately configured highly different the
One connecting portion 131A and second connecting portion 131B.Therefore, even the quantity of through hole of setting and the container cover shown in Fig. 9 (a)
13Z identical situation, fixture 17 also can be distributed.Further, since the upper surface 131A1 of first connecting portion 131A is higher than
Second connecting portion 131B, thus when the fixture 17 being arranged on first connecting portion 131A being rotated using instrument T etc., do not allow
Easily disturb with other fixtures 17.
Additionally, second connecting portion 131B is formed as truncated cone body shape, and upper surface 131B1 tilts for taper.Therefore, with upper
Surface 131B1 as the upper surface 131A1 of first connecting portion 131A compared with the situation that vertical direction is vertically formed, fixture
17 upper end tilts to peripheral direction.Thus, even in the case of being provided with multiple fixtures 17, being also easily guaranteed that instrument T
Entrance gap.
And then, in second connecting portion 131B, through hole is separated with each two for a unit α, in separate unit α each other
Between there is sufficiently large distance (as shown in fig. 7, meeting the relation of W1 ＞ W2).Therefore, it is possible to be easily guaranteed that between the entrance of instrument T
Gap, and the decline of work efficiency can be suppressed.
