At the same time, the L sticky material overflowing from the fitting part of the pot 12 is discharged from the pot notch 120 and guided into the groove of the upper frame 1 to L part by the stopper 25, and then the upper frame 1 hinge The liquid is stored in a container 26 that is removably fitted to the lower part of the body.

13 is the pot pasoki/14' (i- through the upper part of the pot 12 [
- A pressure lid that airtightly covers one part, and a flange-like locking part 13b having a cutout part 131L'i is integrally provided on the outer periphery as shown in FIG. It has a notch 12b corresponding to the locking part 13b, and the other parts are locked. : Fitting part 12JLi-body with a cross-sectional shape to be held and attached to the bayonet
'Closing FiE valley A: All fitting operations of the pressure lid 13 and pot 12 constituting 4 are performed. Reference numeral 16 denotes a nozzle having a communication hole for communicating the inside and outside of the container and attached to the outer upper surface VC of the pressure lid 13, and a pressure adjusting weight 16 is freely set at the tip to adjust the internal pressure of the container.

j The toner adjustment weight 16 protrudes from the opening in the outer cover 5 to the outside air with the pressure cover centered on the lower surface of the outer cover 3
, 17 is a holding shaft, which has a central upper surface VC of the pressure lid 13 and is firmly fastened to the connecting shaft 18 via the pressure lid 13. 1
9 is an inner lid with several small holes and is inserted from the nozzle 16.
-'H installed at the bottom of the pressure lid 13 to prevent the lint etc. from blowing out;
The inner lid packing 2o for removably mating with the connecting shaft 18Jζ section is inserted into the central through hole V, and the pan barb/14 inserted on the outer peripheral wall is pressed against the pressure lid 13 below and held. ing.

21 is a pressure knob for rotating the 13 pressure lids,
It is located on the outside of the lid and is directly connected to the pressure lid 13 by a connecting fitting 26.

The pressure cover body, which is formed by equipping the pressure cover 13 with various parts, is removably fitted into a holder gasket 11 attached to the lower surface of the cover body, and is rotatably provided.

Next, the operating method in the above configuration will be explained.

A pot 12 is stored in a protective frame 1 with its position regulated. The holding shaft 17 of the pressure lid body is fitted into the holder backing 11 attached to the lower surface of the lid body. Pressure lid locking part 13b and pot notch part 12
When the lid is closed and locked on the main body with the pressure lid locked at the position corresponding to b, the pressure lid locking portion 13-

In addition, by riveting a cross-sectional support metal fitting to securely fix it to the rotation stopper metal pan, and by attaching all the locks to this support metal fitting, the entire support metal fitting can be provided with a short length, so that it can be easily rotated in the vertical direction. It can be strongly supported with a thin plate without deforming even when subjected to force.

k. By inserting a stopper into the notch provided in the protective frame and upper frame to regulate and control the position of the pot, there is no possibility that the pot will leak out from the notch in the opening section of the pot. It goes around u etc. 1] and is led to the second drainage channel formed, and the (kV #t
