Description

[Detailed description of the invention] This invention is based on an air pot, more specifically, a resin shoulder body is placed and fixed on the upper end of the body housing a medium bottle, and a lid body with an air pump built into the hinge at one end of the shoulder body. The present invention relates to an air pot which is supported so as to be openable and closable, and has a spout cover attached to the outside of the body to cover a water conduit pipe extending to a water injection pipe.

In conventional air pots, water is supplied through a lift pipe attached to the inner stopper that hangs down to the bottom of the medium bottle, and a water injection pipe that protrudes outside the main body, and water is injected from a spout at the tip of the water injection pipe that opens at the top of the main body. However, with this, the spout was located at a high position, which caused the inconvenience of having to lift the receiver up to the spout whenever pouring water. Therefore, in order to lower the spout to a position optimal for the height of a typical receiver, air pots are provided that are provided with a water guide pipe that is connected to a water injection pipe and extends downward. In order to prevent the water pipe from being damaged or falling off, the area around the water pipe is covered with a spout cover attached to the outside of the fuselage. Because it is stopped, the installation work is troublesome, and because the spout cover has a U-shaped cross section with an opening on the body side, if water overflows to the outside of the water pipe, it may cause rust on the body. There is a drawback.

The present invention was created in view of these drawbacks.
The purpose of the present invention is to provide a spout cover mounting structure for an air pot that does not require screws or other mounting members to attach the spout cover to the body, allows for easy and reliable installation, and prevents the body from rusting. do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, which are examples of the present invention.

In FIG. 1, 1 is a metal body that accommodates a medium bottle 5 and has one mounting hole 2 and two beads 3 formed on the front surface, and 6 is placed on the upper end step 4 of the body 1. a synthetic resin shoulder body fixed to the body 1 by screwing a mounting nut 11 from the inside of the body 1;
Reference numeral 12 denotes a lid body which incorporates an air pump 13 and is supported by a hinge portion 6a at one end of the shoulder body 6 so as to be openable and closable;
1 is a hook mechanism provided at the tip of the lid body 12;
5 is an inner stopper fitted into the mouth of the inner bottle 5. The front surface of the shoulder body 6 has a beak-shaped spouting part 7 having an insertion opening 7a to which the spout of the water filling pipe 16 of the inner stopper 15 corresponds.
As shown in FIG. 2, on the outer surface of the spouting part 7, horizontal protrusions 8 are provided on both sides of the upper part, and engagement claws 9 are provided at the bottom of the protrusions.
is formed. In addition, on the top surface of the spouting part 7,
A receiving pawl 10 that engages with and disengages from the hook pawl 14a of the hook mechanism 14 is provided in a protruding manner.

Reference numeral 17 denotes a cylindrical spouting part cover made of synthetic resin, the upper end opening of which is shaped to fit on the outside of the spouting part 7 of the shoulder body 6, and this upper end opening has a flange facing inward. 18 is formed, and a horizontal protrusion 19 and an engaging pawl 20 are formed on the lower inner surface of the flange. A hook portion 21 having a downwardly hanging tip is integrally provided on the rear surface of the spout cover 17, and an engagement hole 22 is provided below the hook portion 21.

Reference numeral 23 denotes a water conduit, the upper end of which fits into the outer periphery of the insertion port 7a of the spouting part 7, and the lower end thereof integrally provided with a lower plate 24 for closing the lower end opening of the spouting part cover 17. ing. An opening 25 for inserting a finger is formed in the lower plate 24, and two elastic pieces 26 and 27 are erected on the front and rear edges of this opening, and the rear side of the rear elastic piece 27 is provided with the above-mentioned pouring material. A hook 27a that engages with the engagement hole 22 of the section cover 17 is formed. 2
Reference numeral 8 denotes a connector for connecting and holding the elastic pieces 26 and 27. When the front elastic piece 26 is bent forward by inserting a finger into the opening 25, the rear elastic piece 27 is connected and held by the connector 28. Following the front elastic piece 26, it bends forward, and the hook 27a comes out of the engagement hole 22.
The water conduit 23 can be removed from the spout cover 17.

The spout cover 17 is integrated with the shoulder body 6 into the body 1.
mounted on. That is, when the upper end opening of the spouting part cover 17 is fitted into the spouting part 7 of the shoulder body 6 from the horizontal direction, the protrusion 8 of the spouting part 7 is inserted into the spouting part cover 1.
7 is fitted between the flange 18 and the protrusion 19, and the engaging claws 9 and 20 engage with each other just before the fitting is completed, so that the spout cover 17 is vertically moved relative to the shoulder body 6.・Fixed in the front and back direction. The shoulder body 6 and spout cover 17 integrated in this way are attached to the body 1.
When placing the spout cover 17 on the upper step 4, insert the hook 21 of the spout cover 17 into the mounting hole 2 of the body 1, and then attach the shoulder body 6.
and the spouting part cover 17 are pushed down together. As a result, the hook portion 21 engages with the lower edge of the attachment hole 2, the inner surface of the hook portion 21 is pressed against the bead 3, and the rear surface of the spout cover 17 is brought into close contact with the front surface of the body 1. In this state, by screwing the mounting nut 11 into the threaded portion 6b of the shoulder body 6 from the inside of the body 1, the upper end step 4 of the body 1 is connected to the shoulder body 6 and the mounting nut 1.
1 and the shoulder body 6 is fixed to the body 1.

As mentioned above, the spout cover 17 has an upper part that is positioned and fixed in the vertical and front-back directions relative to the spout part 7 of the shoulder body 6, and a lower part that is positioned and fixed in the front-rear direction with respect to the body 1. Even if an external force is applied to the cover 17 in any of the vertical, horizontal, and longitudinal directions, it will not rattle or come off.

Generally, there are two types of air pot shoulder bodies: those made of resin and those made of metal.Resin shoulder bodies allow for easy disassembly of the shoulder body and body by removing the mounting nuts, and are easy to pour out. It has the feature that protrusions, engaging claws, etc. can be integrally formed on the part. The present invention takes advantage of the characteristics of the resin shoulder body to provide an air pot that is easy to assemble and can be replaced even if the spout cover is damaged.

In the above embodiment, when the upper end of the spouting part cover 17 is fitted to the outside of the spouting part 7 of the shoulder body 6, the upper surface of the collar part 18 becomes flush with the upper surface of the peripheral edge of the shoulder body 6. When the lid 12 is closed, no gap is generated between the spout cover 17, the shoulder body 6, and the lid 12, and the air pot can have a good appearance.

Further, the fitting structure between the spouting part cover 17 and the spouting part 7 of the shoulder body 6 is not limited to that of the above embodiment. Any structure that can be fixed in the vertical and front-back directions is sufficient.

As is clear from the above explanation, according to the present invention, the upper part of the spout cover is fitted into the spout part of the shoulder body from the horizontal direction, and the lower part is fitted into the mounting hole of the body from above. Therefore, the spout cover can be easily attached to the torso and shoulder body without using any screws or other mounting parts, and since the spout cover is fixed in two places, the top and bottom, it can be installed extremely firmly. . Since the spout cover is cylindrical, even if water overflows to the outside of the water pipe or steam enters the spout cover, the water will not adhere to the body, preventing rust. be able to.
