Description

[Detailed description of the invention] The present invention relates to an air pot in which a bellows is compressed to forcefully send air into the pot and liquid in the pot is poured out, and the rise and fall of a pushing body that compresses the bellows is regulated. Regarding the safety device of air pots.

Conventionally, this type of air pot has been provided with a lever that selectively prevents the pusher from rising and lowering, especially in order to prevent hot water from being poured out by accidentally pressing the pusher when the lid is opened. The display and operation knob were provided at the rear of the upper part of the lid, making it difficult to tell whether or not the pushing body was in a state where the lifting and lowering was blocked, and also making it difficult to operate the lever. As a result, most of the pushing bodies are always in a state where they can be raised and lowered and do not perform their original function.

The purpose of the present invention is to improve the above-mentioned conventional drawbacks, to make it easier to distinguish the regulation display for raising and lowering the pushing body, and to improve its operability.
An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 designates a lid body that houses a bellows 2 and is provided on a pot body 3 so as to be openable and closable with a pivot shaft 4 at the rear thereof.A cylindrical part 5 with an opening is provided in the center of the upper surface of the lid body 1. At the lower end of this cylindrical section 5, there is provided a flange section 7 having a plurality of notches 6 and erected toward the center, and furthermore, an opening window 8 is provided at approximately the center of the front surface and is integrally formed with synthetic resin or the like. is formed. Reference numeral 9 denotes a pushing body for the bellows 2 provided in the cylindrical portion 5, and this pushing body 9 includes a disc portion 10 with which the hand is placed during operation, which has a diameter slightly smaller than the inner diameter of the cylindrical portion 5, and an end portion of the flange portion 7. The pusher body 11 has a cylindrical pusher main body 11 with a diameter slightly smaller than the inner diameter, and a plurality of stoppers 12 that loosely fit into the plurality of notches 6 of the flange portion 7 are provided on the outer periphery of the pusher main body 11. A plurality of protruding pieces 13 are provided at the lower end of the pusher body 11 to extend radially outward from the back surface of the disc part 10, and a plurality of protruding pieces 13 are provided at the lower end of the push body 11, and a plurality of protruding pieces 13 are provided at the center of the back surface of the disc part 10. is integrally formed of synthetic resin or the like with cross-shaped ribs 14 erected.

Reference numeral 15 denotes a lever having a substantially triangular cross section, and this lever 15 extends one lower end thereof to provide one stopper 12 of the pusher body 9 on the front side of the lid body 11, and extends to the lower end of the pusher body 11. An engaging piece 17 having a substantially U-shaped groove 17a that engages with the guide portion 16 provided as a slanted piece is provided, and the horizontal dimension is smaller than the vertical dimension from the groove 17a, which is approximately the center of the other inclined piece. At the elongated position, there is an operating knob 18 protruding from the opening window 8 of the lid body 1, a display section 19 facing the opening window 8, and an operating brake pawl consisting of a substantially U-shaped notch groove. 20, and a projecting piece 21 at its lower end that locks the end surface near the engaging piece 17, and is integrally formed of synthetic resin or the like.

Reference numeral 22 denotes a protection plate, which engages and loosely fits into the convex portion 23 integrally provided on the upper end surface of the bellows 2 by hollow molding or the like and the inner diameter of the pusher main body 11 of the pusher 9, and It is formed into a substantially circular disk portion with an engaging portion 24 erected upward in a ring shape at the center.

Reference numeral 25 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 26 built into the bellows 2. The check valve 25 and the inlet port 2a of the bellows 2 are maintained with a constant opening by the protection plate 22. Note 29
is the seal packing of the check valve 25, and 2 is the seal packing of the check valve 25.
Reference numeral 7 indicates an opening/closing lever for unlocking and locking when the lid body 1 is opened and closed by the pivot 2, 28 indicates a spout for pouring liquid in the pot, and 29 indicates a handle.

To explain the operation in the above configuration, first, when dispensing the liquid in the pot, the display part 1 of the lever 15 displayed on the opening window 8 on the front of the lid body 1 is pressed.
9, and then place your hand on the top of the lid 1, which is sized to fit in your palm, and slide your thumb horizontally on the operation knob 18 protruding from the opening window 8, to turn the lever 15. When the pusher 9 is rotated within the lid 1 through the pusher 9, the plurality of stoppers 12 of the pusher 9 are positioned above the notch 6 of the flange 7, as shown in FIG. In this state, the pushing body 9 can be lowered and the liquid in the pot can be poured out. On the other hand, when dispensing the liquid in the pot is completed, place your hand on the top of the lid 1 and use your thumb to slide the operating knob 18 in the opposite direction to the above to rotate the pusher 9. This prevents the stopper 12 and the notch 6 from being aligned with each other, thereby preventing the pushing body 9 from descending.

As is clear from the above description, according to the present invention, a pusher body that presses the bellows and can be moved up and down is provided on the top of the lid body with a built-in bellows, and rotates together with the pusher body to raise and lower the pusher. An engaging piece provided at one end of the lever for selectively blocking the movement is engaged with a guide portion extending from the lower end of the pushing body on the front side of the lid body, and the other end having the operation knob is connected to the pushing body. The opening window, located on the vertical wall of the front wall of the lid body, is located outward from the engaging part of the lever and the lever, and faces the opening window along with the display part.
The horizontal sliding operation of the lever that restricts the sliding of the pushing body is performed by keeping the operating knob, which is the point of effort, on the same plane as the point of action of the engaging part of the lever that engages with the pushing body and rotates. Since the point of force and the point of action are placed close to each other, it can be carried out smoothly while fully supporting the main body with one hand, and the lever itself can be made compact and simple, so distortion and deformation after molding are minimized, and the desired shape can be achieved. The shape can be obtained, and the operability after assembly to the lid body is further improved and stabilized.

Furthermore, since the operating knob for the lid is arranged on the front of the lid together with the display, it is possible to easily and reliably read whether the pusher is in a slidable state or in a restricted sliding state.
