Description

[Detailed Description of the Invention] The present invention relates to an air pot in which liquid in a medium bottle is pushed out to the outside by pressurized air from an air pump disposed above the pot.

In conventional air pots, the inner bottle was housed in an outer case made of sheet metal, and the air pump was housed inside a lid separate from the outer case, so the overall structure of the pot was It becomes complicated, and the number of parts and assembly man-hours increase, resulting in high costs.

The present invention was made in order to improve the problems of the conventional air pot as described above, and the medium bottle and air pump are each housed in an exterior body made of a synthetic resin integral body, and the entire pot is It is an object of the present invention to provide an air pot whose structure can be simplified.

Hereinafter, the air pot of the present invention will be explained based on the illustrated embodiment. The air pot of the embodiment shown in FIGS. Part 2
Each of the storage chambers 5 and 6 of the exterior body 1 is formed by integrally molding the cylindrical wall 3 constituting the air pump storage chamber 6 in the upper part of the body, and each of the storage chambers 5 and 6 accommodates a medium bottle 7 and an air pump 8, respectively.
An inner plug unit 19 is interposed between t7 and the air pump 8.

The exterior body 1 is integrally molded from a synthetic resin material,
A partition wall 4 that partitions a medium bottle storage chamber 5 and an air pump storage chamber 6 is integrally formed on the exterior body 1.

A handle 20 is integrally formed on the rear outer surface of the body 2 of the exterior body 1.

A stopper insertion hole 17 communicating with the bottle opening 7a of the medium bottle 7 is formed in the partition wall 4 of the exterior body 1 at approximately the center thereof.

The plug body 11 of the inner plug unit 9 is removably fitted into the plug insertion hole 17.

The lower end 2a of the body 2 constituting the medium bottle storage chamber 5 is open, and a bottom member 21 is screwed into the lower end opening of the body 2.

Approximately in the center of the bottom member 21 is a medium screw member 22 that also serves as a bottle holder.
are screwed together, and the medium bottle 7 is tightly held by the medium screw member 22 between the medium screw member 22 and the lower surface of the opening edge of the stopper insertion hole 17.

The inner stopper unit 9 includes a stopper body 11, an inner bottle tube 14 for drawing up liquid that extends downward, and an outer bottle tube 15 for dispensing liquid that extends laterally.
It is installed and configured.

The bottle inner tube 14 and the bottle outer tube 15 communicate with each other via the stopper water passage 13, and the bottle inner pipe 14, the stopper inner water passage 13, and the bottle outer pipe 15 communicate the inside and outside of the medium bottle 7. It constitutes a series of fluid passages 10.

A vent passage 12 is formed in the stopper 11 of the inner stopper unit 9 for blowing pressurized air from the air pump 8 into the inner bottle 7.

Upper end 3a of cylindrical wall 3 constituting air pump storage chamber 6
is open upwards.

Further, an opening 23 is formed on the front side of the cylindrical wall 3 by cutting out the upper end in the vertical direction.

The distal end side of the bottle outer tube 15 is made to protrude outward from this opening 23.

Recessed grooves 25.25 are formed in the longitudinal direction on both side surfaces 24.24 of this opening 23, respectively.

These recesses R25, 25 are for fitting a hanging piece 35 of a pump holding member 33, which will be described later.

Further, guide grooves 26, 26 are formed in the inner surface of the cylindrical wall 3 in the vertical direction at positions displaced by 90 degrees to the left and right from the position of the opening 23, respectively.

The guide grooves 26, 26 function as a guide for the pump top plate when positioning the air pump 8 and driving the pump.

A recess 27 is formed on the inner rear side of the cylindrical wall 3.

This recess 27 is for fixing the pump holding member 33 by fitting the pump holding member 33 into the recess.

The air pump 8 is of a bellows type and can be moved in and out of the pump housing chamber 6.

The air pump 8 is housed in a state where it is placed on the upper part of the plug body 11, and at this time, a pump discharge port 29 formed in the pump bottom plate 28 communicates with the water passage 12 inside the plug.

The pump top plate 30 of the air pump 8 has an outer diameter that is approximately the same as the inner diameter of the cylindrical wall 3, and a guide groove 2 on the inner surface of the cylindrical wall 3 is located at an opposing position on the outer periphery of the pump top plate 30.
An outwardly directed projection 32°32 is formed which engages 6.26.

The protrusion 32.32 of the guide groove 26.2 is inserted into the guide groove 26.2 when the pump is driven.
It moves up and down along 6.

A pump suction port 31 is formed in the center of the pump top plate 30.

This suction port 31 is closed with a finger when the pump is pressed.

A pump holding member 33 for preventing the air pump from being pulled out is detachably attached to the upper end 3a of the cylindrical wall 3.

This pump holding member 33 is constructed by integrally forming a downwardly extending hanging piece 35 on the outer periphery of a narrow strip-shaped circular annular plate 34.

The annular plate 34 is formed to have an outer diameter that is approximately the same as the inner diameter of the cylindrical wall 3 and an inner diameter that is slightly smaller than the outer diameter of the pump top plate 30.

The hanging piece 35 has the same width as the opening width of the cylindrical wall opening 23 and the height almost the same as the height of the cylindrical wall 3, and the lower end of the hanging piece 35 has a hole for passing the outer bottle tube 15. A notch 36 is formed.

Also, vertical protrusions 3B, 3B are formed on both side surfaces 37, 37 of the hanging piece 35, respectively, to engage with recesses i25, 25 formed in the opening side surfaces 24, 24.

A small projecting piece 39 is integrally formed downward on the outer periphery of the annular plate 34 and on the opposite side of the hanging piece 35. A convex portion 40 is formed to fit into the concave portion 27 formed therein.

This pump holding member 33 includes vertical protrusions 38 of the hanging piece 35,
3B is pushed downward while engaging with the grooves 25, 25 of the opening 23, and the convex part 40 of the small projection piece 39 is elastically fitted into the concave part 27 on the rear inner surface of the cylindrical wall 3. 3
Attached to the top opening of the

In this air pot, when pouring liquid into the medium bottle 7,
Remove the pump holding member 33, insert your finger into the cylindrical wall opening 23 and take out the air pump 8 upwards, and then pull out the inner plug unit 9. It is now possible to drain the liquid.

In addition, in this air pot, when the air pump 8 is pressed, the pressurized air is blown into the medium bottle 7 through the in-stop conduit passage 12, and the pressurized air causes the liquid W in the medium bottle 7 to flow into the bottle tube. 14, it is possible to pour out to the outside through a series of liquid passages 10 consisting of a water passage 13 inside the stopper and a tube 15 outside the bottle.

In the air pot of the embodiment shown in FIG.
A partition wall that partitions the pump storage chamber 6 and the pump storage chamber 6 is constructed by a separate member, and the partition wall 41 is attached to the lower surface of a stepped portion 42 formed at the upper end of the body by being pressed from below.

That is, the partition wall 41 is pressed upward by the bottle opening 7a of the medium bottle 7, which is pressed by the medium screw member 22 of the bottom member 21 (FIG. 1).

Note that the other configurations are the same as in the case of FIG. 1, so the explanation thereof will be omitted.

Next, to explain the effects of the present invention, the air pot of the present invention has each housing chamber of the exterior body 1, which has a cylindrical wall 3 for housing the pump integrally molded with synthetic resin on the upper part of the body 2 for housing the medium bottle. Since the inner bottle 7 and the air pump 8 are housed in the inner chambers 5 and 6, the structure of the exterior part of the pot is simplified, unlike the conventional case where the inner chamber bottle and the air pump are each made of separate parts. Compared to the case of an air pot housed in a case and a lid, the number of parts and the number of assembly steps can be reduced, and since the exterior body 1 is integrally molded, the pot as a whole becomes more robust.
