Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air-type pot in which a bellows is compressed to forcefully send air into the pot, and liquid in the pot is poured out.

Conventionally, in this type of air-type pot,
In order to prevent hot water from being poured out unexpectedly by accidentally pressing the pusher, it is normal to provide a lever that selectively prevents the pusher from moving up and down. However, it was complicated and difficult to assemble, resulting in high costs.

The present invention solves the above-mentioned conventional drawbacks and provides a pneumatic pot equipped with a lever for regulating the sliding of a pushing body, which has a simple structure and is easy to assemble.One embodiment of the present invention will be described below. will be explained with reference to the attached drawings.

In the figure, reference numeral 1 designates a thin-walled, hollow lid that accommodates a telescopic bellows 2 and is provided on a pot body 3 so as to be openable and closable.A cylindrical portion 4 that opens upward is provided at the center of the top surface of the lid. At the lower end of the cylindrical portion 4, there is provided a flange portion 6 having a plurality of notches 5 and erected horizontally in the center direction. Further, an opening window 7 is provided approximately at the center of the front surface of the lid body 1, and thin ribs 8 protruding outward are provided at positions on the outer periphery of the cylindrical portion 4 at arbitrary angles from the center of the opening window 7. It is vertically extended and erected, and is integrally formed of synthetic resin or the like.

Reference numeral 9 denotes a pushing body for the bellows 2 provided in the cylindrical portion 4, which has a slightly smaller diameter than the inner diameter of the cylindrical portion 4, and includes a disk portion 10 on which the hand is placed when pressing, and the flange portion 6.
A cylindrical pusher main body 11 having a diameter slightly smaller than the inner diameter formed by the inner end of the pusher main body 11; A plurality of stoppers 12 extend from the back surface of the pusher body 10 to near the lower end thereof, and a plurality of protruding pieces 13 protrude radially outward from the lower end of the pushing body 11. A cross-shaped rib 14 is erected at the center of the back surface and is integrally formed of synthetic resin or the like.

Reference numeral 15 denotes a lever having a substantially triangular cross section curved to one side, and a guide portion provided by extending the lower end of the inwardly curved piece to extend one stopper 12 of the pusher body 9 to the lower end of the pusher body 11. An engaging portion 17 having a substantially U-shaped groove 17a that engages with the groove 16 is provided,
Approximately at the center of the curved piece close to the inner wall of the lid 1, there are an operating knob 18 provided to protrude from the opening window 7 of the lid 1, and a display section 19 provided to be visible from the opening window 8. Further, a claw part 20 is provided at the end thereof, which is formed by a substantially U-shaped notch groove, and which applies a brake during operation, and is reversibly provided at the lower end thereof, so that the tip thereof is located near the engagement piece 17. It is provided with a reversible piece 22 that locks onto a protrusion 21 provided on the inner wall of the body, and is reinforced with connecting ribs 30 at both ends of both pieces, and is integrally formed of a synthetic resin such as polypropylene.

23 is a protection plate, which includes a convex portion 24 integrally provided on the upper end surface of the bellows 2 by hollow molding or the like;
An engaging portion 25 that engages and loosely fits into the inner periphery of the pusher main body 11 of the pusher 9 is provided upwardly in a ring shape at the center thereof, and is formed in a substantially disk shape.

Reference numeral 26 denotes a check valve that is vertically slidably provided at the suction port 2a at the upper end of the bellows 2, and is urged upward together with the pusher 9 by a spiral return spring 27 built into the bellows 2. The protective plate 23 maintains a constant opening between the check valve 26 and the suction port 2a of the bellows 2. Note that 28 is a seal packing that is provided in the check valve 26 and closes the inlet port 2a of the bellows 2 when the check valve 26 slides downward. Reference numeral 29 denotes an opening/closing lever for unlocking and locking when opening and closing the lid 1.

To explain how to assemble the above structure, first, the pusher 9 is placed inside the inner diameter of the cylindrical portion 4 and flange portion 6 of the lid 1, and then the reversible piece 22 is opened and the lever 15, which is formed into a substantially V-shape, is opened. While pressing the inner curved piece and the outer curved piece to further deform the approximately V-shaped tip angle to an acute angle, align it with the narrow rib on the outer periphery of the cylindrical part 4 of the lid body 1, as shown in FIG. Press fit. As the press-fit progresses, the guide portion 1 of the pushing body 9 will move as shown in FIG.
6 is engaged with the groove 17a of the lever 15, the operating knob 18 of the lever 15 is inserted into the opening window 7 of the lid body 1, and the reversible piece 22 of the lever 15 is further rotated and bent in the direction of the arrow A. Tip protrusion 2
1 and complete.

To explain the sliding operation in this configuration, first, when dispensing the liquid in the pot, the operation knob 1 protruding from the opening window 7 on the front of the lid body 1 is used.
8 in the horizontal direction and the pusher body 9 is rotated inside the lid body via the lever 15, the plurality of stoppers 12 of the pusher body 9 are pressed against the cutouts of the flange portion 6, as shown in FIG. It is located above the notch 5. In this state, the pushing body 9 can be lowered, and the pressure of the pushing body 9 causes the check valve 26 to close the inlet port 2a of the bellows 2, and further, as the pushing body 9 presses down, air is forced to flow from inside the bellows 2 into the pot. It is used for dispensing liquid. On the other hand, when dispensing the liquid in the pot is completed, the operation knob 18 is slid in the opposite direction to rotate the push plate 9 so that the stopper 12 and the notch 6 do not match, and the push body This prevents the number 9 from falling.

As is clear from the above description, according to the present invention, the lever that selectively blocks the pushing body is deformed using the elasticity of synthetic resin and inserted into the lid body, and the jig or the like is inserted using the hinge effect. Since it is locked without the need for it, its assemblability is further improved, and its structure is simple, and it is possible to reduce assembly costs and material costs.

Furthermore, in synthetic resin molding, dimensional deformation may occur depending on the molding conditions, but in the case of a lever, the operating force must be kept within a certain range, which is contradictory. The thin ribs standing upright on the outer circumference of the body are in contact with each other to reduce friction, and the height of these thin ribs absorbs the dimensional change of the reversible piece, which affects the operating force the most, resulting in changes in the operating force. It also makes it possible to reduce
