Description

[Detailed Description of the Invention] The present invention relates to a charm bottle that has a built-in medium bottle with both upper and lower ends open.

Traditionally, mamahopintoshi, which has a medium bottle with an open top, has a so-called hand pot type in which you hold the handle in your hand and tilt the main body to inject liquid from the top spout to the outside, and a built-in air pump. By pressing this air pump,
The so-called air pot type is generally used, in which the liquid inside is injected to the outside through a water injection pipe.

Hand pot type magic bottles have a simple structure and are therefore inexpensive, but they have the disadvantage that filling operations are troublesome, and large-capacity ones are heavier, making them even more difficult to operate.

In addition, with air pot type magic bottles, liquid can be easily injected by simply pressing the air pump, but the injection mechanism is complicated, which increases costs and poses safety issues. there were.

The present invention was devised in view of the above-mentioned conventional drawbacks, and an object of the present invention is to provide an inexpensive magic bottle that is excellent in liquid injection operability and safety.

Fig. 1 shows an example of the magic bottle according to the present invention, in which 1 is a metal body, 6 is a medium bottle made of a vacuum double bottle with both upper and lower ends open, 8 is a synthetic resin shoulder body, and 29 is a stopper. 36 is a bottom body, and 45 is a liquid injection pipe.

An inner winding part 2 is formed at the upper end of the body 1,
An annular body 12 whose upper end surface is in contact with the inner winding part 2 is disposed inside the body 1, and a female thread 13 provided on the inner peripheral surface of the annular body 12 is connected to a female thread 13 provided on the outer peripheral surface of the lower end of the shoulder body 8. By screwing the male screw 9, the shoulder body 8 and the body 1 are fixed together.

Note that 15 is a set screw.

A handle shaft insertion hole 3 is formed near the upper end of the body 1, and after inserting the handle shaft 16a of the handle 16 into the handle shaft insertion hole 3, a bushing 17 and an E-ring 18 are fitted onto the handle shaft 16a. The bushing 17 and the annular body 12 engage with each other to restrict the downward movement and slow rotation of the annular body 12, thereby facilitating the screwing operation of the shoulder body 8 to the annular body 12.

A female screw 10 is formed on the inner peripheral surface of the shoulder body 8, and a male screw (first screw) 20 of an upper mouth member 19 made of synthetic resin is screwed into the female screw 10 from above. .

The female thread 10 and the male thread 20 are provided with ratchet teeth 10a, 20a as shown in FIG. 2, and are configured so that once they are screwed together, they will not loosen.

The upper spout member 19 has a hot water supply spout 21 at the top, and a bottle spout holder 22 for receiving the upper end opening 6a of the medium bottle 6 at the bottom. A sliding ring 27 provided with a mouth rubber 26 is slidably arranged.

Then, when the cap rubber 26 and the sliding ring 2 are fitted into the upper end opening 6a of the medium bottle 6 and the upper spout member 19 is tightened, the upper spout member 19 and the sliding ring 27 are slid relative to each other. is configured to operate.

22a, 27a, and 27b are protrusions for obtaining sliding properties.

When it is turned and when it is turned outward as shown by the dashed line, it is elastically positioned at each position by a presser spring 55.

Next, a method for assembling the magic bottle having the above structure will be explained.

First, the lower mouth member 41 is fitted into the center of the bottom body 36, the liquid injection pipe 45 is inserted from the outside, and the nut 47 is screwed onto the inner end 46 of the liquid injection pipe 45. The lower mouth member 41 and the liquid injection pipe 45 are integrated.

Next, place the lower inner winding part 4 of the body 1 on the stepped part 38 of the bottom body 36, insert the bottom mounting nut 31 into the body 1 from above, and screw it onto the male screw 37 of the bottom body 36. As a result, the inner winding portion 4 at the lower end of the body 1 is clamped and fixed.

Then, the medium bottle 6 is inserted into the body 1 from above, and the lower end opening 6b of the medium bottle 6 is pressed against the lower mouth member 41 via the mouth rubber 40.

Here, the annular body 12 is arranged inside the upper end of the body 1, and the handle shaft 16a is prevented from being removed with a bush 17 and an E-ring 18, and the bush 17 restricts the descent and reverse rotation of the annular body 12. In this state, after screwing the male screw 9 of the shoulder body 8 onto the annular body 12, the set screw 1 is inserted from the outside of the body 1.
5 into the annular body 12 and the shoulder body 8, and then connect the body 1 and the annular body 1.
2 and the shoulder body 8 are integrated.

After that, the cap rubber 26 and the sliding ring 27 are placed on the upper end opening 6a of the medium bottle 6, and the upper cap member 19 is inserted into the shoulder body 8 from above.
The inner bottle 6 is pushed down through the cap rubber 26 and the sliding ring 27 to open the openings 5a at the upper and lower ends of the inner bottle 6.

6b is clamped and fixed between the upper opening member 19 and the lower opening member 41 with airtightness.

Then, the plug body 29 is screwed onto the male thread 24 of the hanging piece 23 of the upper opening member 19 to complete the assembly.

As mentioned above, each part of this magic bottle can be assembled sequentially from above, so assembly work is easy.

In particular, in the case of the conventional method of fixing the medium bottle 6 by tightening it from below, it is easy for the center of the medium bottle 6 to shift during assembly, but in the present invention, while aligning the center of the medium bottle 6, 19, so there is no need to worry about misalignment.

Moreover, since the weight of the middle bottle 6 does not act on the upper mouth member 19 for tightening the middle bottle 6, the upper mouth member 19 and the shoulder body 8
There is no need to worry about the screw connection loosening.

Note that the first screw 20 and the second screw 2 of the upper opening member 19
4 are all male threaded, but it goes without saying that they may be female threaded in relation to the shoulder body 8 and the plug body 29.

As is clear from the above explanation, according to the present invention, the upper and lower end openings of the medium bottle are clamped and fixed by the upper and lower opening members, so there is no fear of liquid leakage, and there is no need to worry about liquid leakage. Since the bottle is made of a vacuum-made double bottle, its heat retention is no different from that of conventional magic bottles.

Furthermore, the liquid content can be poured out by simply opening and closing the water stop valve on the injection pipe, so there is no need to lift the handle, which provides good operability and an extremely simple structure. You can get cheap magic bottles.
