Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for tightening a medium bottle of a liquid container, and particularly to a device for tightening a medium bottle having openings at the top and bottom.

Conventionally, liquids have been manufactured by incorporating a medium bottle, such as a so-called double-ended magic bottle, with opening holes at the top and bottom, and connecting a water level pipe, water injection pipe, etc. from the bottom opening hole of the medium bottle through a connecting pipe. Containers are suggested. In this type of liquid container, it is necessary to tighten the medium bottle in order to bring the top opening hole of the medium bottle into close contact with the bottle opening of the shoulder body. Therefore, as in the case of ordinary medium bottles that do not have an opening hole in the bottom, the upper end of the tightening body screwed onto the bottom body is slid into contact with the bottom of the medium bottle, and this tightening body is screwed against the bottom body. One possible method is to tighten the medium bottle by advancing the bottle.

However, with this method, the connecting tube connected to the bottom opening hole of the medium bottle protrudes outward, so when you try to tighten the bottom of the medium bottle with the tightening body, the connecting tube gets in the way and makes it difficult to tighten. The disadvantage is that you cannot rotate your upper body.

The present invention has been made in view of these conventional drawbacks, and its purpose is to provide a medium bottle tightening device for a liquid container that can easily tighten and secure a medium bottle without the connecting pipe getting in the way.

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

FIG. 1 shows an air pot which is an embodiment of the present invention, in which a medium bottle 2 consisting of a double vacuum bottle is housed inside a metal exterior body 1 constituting the container body.
The upper end opening hole 2a of this medium bottle 2 is supported by a bottle opening receiving part 3a of a shoulder body 3 placed and fixed on the upper end of the outer case 1 via a cap rubber 4. An opening hole 2b is provided at the center of the bottom of the medium bottle 2, and a connecting gasket 5 is tightly attached to the bottom opening hole 2b by a tightening ring 6.
The lower end of the water level pipe 11 is connected to the water level pipe 11 via a connecting pipe 7 and a connecting tube 9. On the other hand, the upper end of the water level pipe 11 is connected to a communication hole 12 provided in the bottle mouth holder 3a of the shoulder body 3 via a connecting tube 13, and the upper end of the water level pipe 11 is connected to the inside of the medium bottle 2. There is.

Since the medium bottle 2 is a so-called double-ended magic bottle in which the inner bottle and the outer bottle are joined and fixed at the upper and lower ends, there is no need to reinforce the inner bottle with asbestos as in conventional magic bottles. Normally, when asbestos is used, asbestos 1
There is a decrease in heat retention performance of about 1°C/24 hours per piece, but this can be prevented with double-mouthed magic bottles.

An inner plug 14 is attached to the upper surface of the bottle mouth receiving portion 3a of the shoulder body 3, and a water lift pipe 15 and a water injection pipe 16 are integrally attached to the inner plug 14.
A lid 17 is attached to the top surface of the shoulder 3 so as to be freely opened and closed via a seal packing 18. An air pump 19 is built into the lid 17.
The pressurized air is supplied to the seal packing 18 by the operation of
The liquid in the bottle 2 is then pumped through the inner plug 14 to the lift pipe 1 of the inner plug 14.
5 and the water is discharged to the outside via a water injection pipe 16.

In addition, 20 is a medium bottle protector that covers and protects the medium bottle 2.

A water level pipe cover 2 having a see-through window 24a at a position corresponding to the water level pipe 11 is provided on the front side of the exterior body 1.
4 is attached, and the liquid level in the water level pipe 11 can be visually observed through this see-through window 24a.
Further, behind the water level pipe 11, a display back plate part 26 with a striped pattern or the like printed is provided integrally with the exterior body 1, so that the liquid level inside the water level pipe 11 can be clearly confirmed. ing.

On the inner surface of the bottom of the exterior body 1, there is a female thread 30 on the inner peripheral surface.
An annular member 30 (fixed portion) having a diameter a is attached, and a bottom body 31 is screwed onto a female thread 30a of this annular member 30. Note that 32 is a rotating sole fitted to the bottom surface of the sole body 31. A female screw 31a is provided on the inner circumferential portion of the bottom body 31, and a tightening screw body 33 is screwed into the female screw 31a so as to be freely advanced and retractable. A substantially cylindrical tightening support 34 is slidably mounted on the upper surface of the tightening screw body 33, and a plurality of ribs 34a are provided radially protruding from the outer periphery of this tightening support 34. and an insertion opening 34b cut out in a U-shape through which the connecting tube 7 can be freely inserted.
is formed. Note that the insertion opening 34b is not limited to a U-shaped notch and may be a long hole, but in the case of a notch, the tightening support 34 and the tightening screw body 33 are installed after the connecting pipe 7 is attached. Workability is good because it can be moved. The outer end of the rib 34a is connected to a plurality of guide grooves 30b formed at the upper end of the annular member 30.
It is engaged with and guided so that it can move up and down.

Therefore, when the tightening screw body 33 is rotated and screwed upward with respect to the bottom body 31, the tightening support 34 is prevented from rotating by the engagement between the rib 34a and the guide groove 30b. Therefore, it moves only upward while slidingly contacting the tightening screw body 33, and the tightening support body 34
The upper end of the bottle pushes up the bottom of the medium bottle 2. As a result, the upper opening hole 2a of the medium bottle 2 can be brought into close contact with the bottle opening receiving part 3a via the cap rubber 4, and the medium bottle 2 can be tightened and fixed.

Note that if the connecting pipe 7 connected to the bottom opening hole 2a of the medium bottle 2 is made of a flexible material, the connection pipe 7 can be arranged between the bottom opening hole 2b of the medium bottle 2 and the water level pipe 11.
Even if there is a slight misalignment with the hole 1a of the exterior body 1 corresponding to the lower end, the arrangement can be made with a margin, and the resulting misalignment with the insertion opening 34b of the tightening support 34 can also be avoided. Can be easily modified.

Normally, in order to store the medium bottle 2, the annular member 30 is attached to the lower end of the outer case 1, and then the medium bottle 2 is inserted from the lower end opening of the outer case 1. If the size of the bottle is small and the gap with the medium bottle 2 is small, the medium bottle 2 cannot be inserted when the annular member 30 is first attached. Therefore, in such a case, first insert the inner bottle 2 into the exterior body 1, and then assemble the annular member 30, the connecting pipe 7, the tightening support 34, and the bottom body 31 in this order.

In the above embodiment, the bottom body 31 and the tightening screw body 33 are constructed as separate bodies, but they may be constructed as an integral part. In this case, the tightening support 34 can be tightened by screwing the integral part into the annular member 30.

2 and 3 show a second embodiment of the present invention,
A vertical guide rib 3 is provided on the outer surface of the tightening support 34.
4c is provided protrudingly, and this guide rib 34c is connected to the bottom body 31.
The guide grooves 31b are vertically movably engaged with a plurality of guide grooves 31b formed on the inner surface of the upper end (fixed part).
Also in this case, by screwing the tightening screw body 33 into the bottom body 31, the tightening support body 34 can be moved only in the vertical direction.

4 and 5 show a third embodiment of the present invention,
A tightening screw body 33 is attached to the inner flange 31c at the lower end of the bottom body 31.
are rotatably fitted together, and the tightening screw body 33
and the tightening support 34 are screwed together with screws 35, and a guide groove 31 is provided on the inner surface of the bottom body 31 with a guide rib 34d protruding from the outer surface of the tightening support 34.
d in a vertically movable manner. In this case, it is necessary to attach the tightening screw body 33 and the tightening support body 34 to the bottom body 31 in advance, and then attach this to the exterior body 1. At this time, when attempting to attach the bottom body 31 to the annular member 30 attached to the exterior body 1 by screwing, the tightening support 34 rotates together with the bottom body 31, and the insertion port 34b and the connecting pipe 7 interfere with each other. Therefore, it is necessary to attach the bottom body 31 to the exterior body 1 by fitting or locking.

Note that the present invention is not limited to the air pot as in the embodiment, but can be similarly applied to so-called hand pots in which liquid is poured by holding the handle and tilting the main body. Moreover, the water level pipe 11 can also be used as a water injection channel by connecting its upper end to the water injection pipe 16, and in this case, the water pumping pipe 15 of the inner stopper 14 becomes unnecessary.

As is clear from the above explanation, according to the present invention, the medium bottle is tightened using two parts, the tightening support and the tightening screw body, which are guided so as to move forward and backward only in the vertical direction. Even if a connecting pipe or the like is provided in the bottom opening hole of the bottle, the medium bottle can be easily and securely tightened and fixed.
