Description

[Detailed description of the invention] This invention is a lock that locks the vertical sliding of the pressing body of the bellows pump in a pot that uses air pressure to pour out the liquid in the inner container by the pressure of the bellows pump inside the lid. It is related to the device.

Previously, in Utility Application No. 56-108360, the inventor of the present application provided a centrally annular flange at the lower end of the guide cylinder of the lid body, and provided a plurality of convex portions and concave portions in the circumferential direction of this flange. The body is formed into a cylindrical body, a longitudinal groove is bored in the circumferential wall of the cylindrical body to fit with the above-mentioned convex part, and a seat is provided at the lower end of the cylindrical body to pass through the above-mentioned concave part and come into contact with the lower surface of the collar. We devised a pneumatic pot with an operating knob that holds the catch and the upper end protrudes above the lid, but when the pusher was unlocked, the catch fell lower than the thickness of the gripping part of the operating knob. It was discovered that if the operating knob is moved in the locking direction by mistake while the pusher body is lowered, the catch may separate from the clamping part and the pusher body may be pulled out. To provide a pneumatic pot which has a simple structure, is easy to assemble, and reliably prevents the pusher from coming off even in the event of misuse, by further improving the invention.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 surrounds the outer periphery of the inner container 2 with an outer case 3, attaches a drain member 4 to the upper end of the outer case, and provides a liquid supply opening in the center of the drain member. The inner stopper 5 is removably attached to the opening, and the lid body 8 containing the bellows pump 6 and pusher body 7 is attached to the top surface of the draining member so as to be openable and closable, and the bellows pump is pressed by the pusher member to open the inner cavity of the inner stopper. This pot utilizes air pressure to forcefully feed air into the inner container through the inner stopper and discharge the liquid in the inner container from the discharge pipe 9 of the inner stopper, and the lid body 8 consists of an upper lid 10 and a lower lid 11. Ori,
The lid body includes a bellows pump 6, an upper plate 12 placed on the upper surface of the bellows pump, a bushing valve 13, a pusher 7 for pressing the upper surface of the bushing valve, and an operation knob 14 for regulating the vertical movement of the pusher. ing.

The lower lid 11 is fitted to the inner periphery of the lower end of the upper lid 10, and an air exhaust hole is bored in the center of the lower plate via a rubber valve 15.

The upper lid 10 is attached to the draining member 4 via a hinge device 16 so as to be openable and closable, and has a guide tube 17 extending downward from the center of the upper surface.

As shown in FIG. 2, an annular flange 18 is provided on the inner periphery of the lower end of the guide tube 17, and a plurality of convex portions 19 are provided on the inner periphery of the flange 18 at appropriate intervals along the inner circumferential direction. A plurality of recesses 20 and one horizontal hole 33 are provided.

This horizontal hole 33 is formed so as to be located in the vicinity of the inner side 27A of the holding portion of the operating knob that holds the seat of the pusher at the protruding position of the operating knob, which will be described later.

As shown in FIG. 2, the pushing body 7 is integrally formed with a pressing part 22 that moves up and down inside the guide cylinder of the upper lid and a cylindrical body 23 with a lower opening that moves up and down inside the collar 18 of the guide cylinder 17. A contact portion 24 is provided which contacts the bushing valve 13 from the lower surface of the pressing portion 22 at the center inside the cylinder body 23, and a plurality of contact portions 24 corresponding to the recesses 20 of the upper lid 10 are provided at appropriate intervals along the circumferential direction of the lower end of the cylinder body. The catch seat 25 is integrally molded.

The circumferential wall of the cylindrical body 23 has a convex portion 1 of the upper lid 10 and the guide cylinder.
There are provided a plurality of longitudinal grooves 26 through which the cylindrical body 9 can be inserted, and a vertical rib 34 through which the horizontal hole 33 can be inserted. It has been reached.

The lower end of this vertical rib is located above the collar, and when the pushing body is lowered, it fits into the horizontal hole of the collar with almost no gap, and when the operating knob is in the closed position, it is separated from the recess in the collar when the pushing body is inserted.

As shown in FIG. 2, the catch seat 25 protrudes outward from the peripheral wall of the cylindrical body, is provided inwardly from the disc-shaped pressing part on the upper part of the cylindrical body 23, and has a flange 18 between it and the lower end of the cylindrical body. There is a slight step that is more than the thickness of the wall.

This seat 25 is always located below the flange 18 of the guide tube 17, and the longitudinal groove 26 of the cylindrical body is connected to the convex portion 19 of the flange of the guide tube.
When located above, this seat 25 is not located below the recess 20 of the collar, but is always located below the collar 18 away from the recess.

The operating knob 14 has a holding part 27 at the lower end and an operating knob part 28 at the upper end. It is freely rotatable in the direction.

On the upper surface of this knob part, there are paper sheets attached to the open and closed positions, respectively.

The holding portion 27 of the operating knob 14 holds one of the seats 25 of the pushing body 7 between an inner side 27A and an outer side 27B.

The bellows pump 6 has its lower end inserted into an air discharge hole of the lower lid 11 via a rubber valve 15, and is provided with a spring S inside the bellows pump.

The upper plate 12 is formed in an annular shape with a central opening, and is placed on the upper surface of the bellows pump.

The bushing valve 13 is inserted into the upper center opening of the bellows pump and is lifted upward by a spring S.

There is one horizontal hole in the flange and a plurality of FALJ holes in the circumferential wall of the guide cylinder as described above, but one of them is formed so as to be located near the inside and outside of the clamping part at the position where the operating knob comes out. You can.

When assembling the pusher, first place the seat 25 of the pusher 7 on the upper cover 10.
Turn the pushing body while inserting it into the recess 20 of the lid 18 of the guide tube 17 from above, position the catch below the collar 18, position the vertical rib 34 above the horizontal hole 33, and press one catch with the operating knob. It is only necessary to insert the paper into the clamping portions 27 of 14.

When operating the push body, the operation knob 14 is rotated in the circumferential direction along the elongated hole 21 of the top cover 10 to the out position, and the seat 25 of the push body, which is clamped by the clamping portion 27 of the operation knob, is rotated in the circumferential direction. As shown in FIG. 3, the longitudinal groove 26 of the pusher body is positioned above the convex portion 19 of the collar 18 of the guide tube, and the vertical rib 34 is positioned above the horizontal hole 33 of the collar.

When the pusher is pressed in this state, the abutment part 24 of the pusher comes into contact with the upper surface of the bushing valve 13, and the bellows pump 6 is pushed down against the spring, passing from the bottom of the bellows pump into the inner container 2 through the inner cavity of the inner stopper 5. Air can be sent to the inner stopper, and the liquid can be discharged from the inner stopper discharge pipe 9 through the inner stopper water lift pipe 29.

Next, to lock the pusher, turn the operating knob circumferentially along the long groove of the top cover to the closed position in the opposite direction to when the pusher is activated, move the pusher seat in the circumferential direction, and press the pusher. If the longitudinal groove of the body is moved from above the convex part of the brim of the guide tube and the lower end of the cylindrical body without the longitudinal groove of the pushing body is positioned above the convex part, the lower end of the cylindrical body without the longitudinal groove will come into contact with the convex part. If the vertical ribs are brought into contact with each other and the vertical ribs are positioned above and outside the horizontal hole of the collar, the lower end of the vertical ribs will come into contact with the upper part of the collar, thereby locking the pusher.

As described above, in the present invention, a horizontal hole is bored in the circumferential surface of the flange at the lower end of the upper lid force guide cylinder, and this horizontal hole is inserted into the seat of the cylindrical body of the pusher at the position where the operating knob comes out. While it is provided close to the inside and outside of the clamping part, a vertical rib that can be inserted into the horizontal hole is integrally molded on the circumferential wall of the cylindrical body of the pushing body, so that the pushing body can be securely removed even in the event of misuse. It can be prevented.

In other words, even if you operate the operating knob while lowering the pushing body at the position where the operating knob is extended, and the seat clamped by the clamping part of the operating knob descends and moves away from the clamping part to a lower position, it will not move inside or outside the clamping part. In this case, the knob is inserted through the horizontal hole of the collar and comes into contact with the lowered vertical rib, thereby reliably preventing movement of the operating knob.

In addition, both the upper cover and the pusher have a simple structure, and can be locked with just the operating knob, so the number of parts is extremely small.Furthermore, the pusher's seat can be inserted into the recess in the flange of the guide tube from above the top cover, and the pusher can be rotated vertically. The assembly process is very simple as it can be assembled by simply aligning the rib above the horizontal hole in the flange and aligning the catch within the gripping part of the operating knob.
