Description

[Detailed description of the invention] The present invention relates to bottom pouring type containers, particularly bottom pouring type magic bottles, and relates to a mounting structure for attaching the valve member of these liquid containers to the exterior body. be.

Conventional magic bottles have an injection spout formed only at the top, and in order to pour out the contents, the entire magic bottle must be lifted and tilted, or the contents must be pumped with an air pump, etc. It was designed to pump out liquid, and no special spout or valve member was provided. However, in the bottom-pour magic bottle that has been developed in recent years as shown in Figures 1 and 2, openings are formed at the top and bottom of the medium bottle, respectively, and the valve is inserted through the opening at the bottom. Since the liquid content is poured out through the valve, a valve member containing the valve is required, and it is necessary to attach this valve member to the exterior body.

Below, the structure of this bottom pouring type magic bottle will be explained as follows.
This will be explained based on the drawings and FIG. As shown in FIG. 1, this bottom pouring type magic bottle has a container body 1 placed and fixed on legs 2. The container body 1 is the second
As shown in the figure, the exterior body 3 is a cylindrical body 4.
, a shoulder body 5 placed and fixed on the body 4, and a bottom body 6 fixed to the lower end of the body 4,
The legs 2 are fixed to the bottom body 6. Reference numeral 7 denotes a medium bottle, which is a vacuum double bottle, housed in the exterior body 3, and is held under pressure by the shoulder body 5 and the tightening body 8 screwed into the center part of the bottom body 6. has been done.
The upper opening 9 of the inner bottle 7 communicates with the central opening 10 of the outer casing 3 to form an inlet, and the stopper 1
1 is becoming blocked.

On the other hand, a lower mouth pipe 12 is installed vertically at the lower end of the medium bottle 7 , and a lower opening 13 is opened in the lower mouth pipe 12 . It passes through the hole 14 and projects downward. A connecting pipe 15 made of a flexible material such as rubber is connected to the lower mouth pipe 12, and a spout 18 opens at the bottom surface of the main body 1 via a valve 17 operated by an operating member 16. is connected to. Further, a measuring port 19 is formed on the side of the connecting pipe 15,
The metering port 19 is connected to the lower end of a water level pipe 21 via a connecting tube 20. 6a is a bottom cover that covers the lower surface of the bottom body 6; 22 is the water level pipe 21;
This is a front panel equipped with a see-through window 23 through which you can see through.

The present invention provides a valve member 24 incorporating the valve 17.
This relates to the attachment structure for the bottom body 6.

Since the inner container of a magic bottle is generally made of glass, its dimensional accuracy is poor, and the diameter of the lower mouth tube 12 and the position of the lower opening 13 are not always constant and vary depending on the product. On the other hand, the valve member is
In order to ensure operability and the amount of outflow of the contents, it is necessary to set the mounting position very precisely. Therefore, the connecting pipe 15 is made of a flexible material such as rubber, and the connecting pipe 15 is made of a flexible material such as rubber.
It is necessary to be able to always mount the valve member 24 in a fixed position regardless of variations in the valve member 24, and to securely fix the valve member 24 with screws or the like.

However, if the connecting pipe 15 has flexibility,
Attachment work of the valve member 24 to the bottom body 6 may become difficult. That is, it is necessary to cover the bottom cover 6a below the valve member 24 and fix it to the bottom body 6, but if you try to fix the bottom cover 6a and the valve member 24 at once, the bottom cover 6a
At the time of attachment a, the position of the valve member 24 is not determined, so the position of the valve member 24 is easily misaligned, and it is difficult to obtain uniform operability and outflow amount. Also, there is no problem if the valve member 24 is fixed separately from the bottom cover 6a, but it is preferable to minimize the number of screwed locations when assembling this type of product. It is not preferable to screw the bottom cover 6a separately to the bottom cover 6a.

The present invention was developed in consideration of such circumstances, and when assembling the valve member 24 to the bottom body 6,
It can be easily temporarily fixed to set its position correctly, and then fixed together with the bottom cover 6a by screwing it to the bottom body 6 at once.

3 and 4 show the main parts of the present invention. The valve member 24 has a cylindrical outer shell 25 that houses the valve 17, is connected to the connecting pipe 15 at the rear end of the outer shell 25, and has a spout 18 at the bottom of the outer shell 25. It is integrally protruded. Further, wing portions 26 are integrally provided on both sides of the outer shell 25 and project laterally, and screw holes are bored at the tips of the wing portions 26. Further, a small hole 27 is formed at the root of the wing portion 26.

On the other hand, two holding pieces 28 are protruded from the bottom surface of the bottom body 6 and have bifurcated tips to hold the outer shell 25 of the valve member 24. The holding pieces 28 each hold the outer shell 25 with one holding piece 28b at the front end of the wing part 26 and the other holding piece 28a through the small hole 27 of the wing part 26. are doing.

A through hole 29 is formed in the bottom cover 6a at a position corresponding to the spout 18 on the lower surface of the bottom cover 6a.
A spout cover 30 is provided around the periphery of the spout cover 30 to protrude downward. Further, screw holes are bored in the overhanging portions 31 on both sides of the bottom cover 6a.

Therefore, in order to attach the valve member 24 to the bottom body 6 in the structure of the present invention, the valve member 24 is first connected to the connecting pipe 15, and then the valve member 24 is attached using the elasticity of the holding piece 28. Then, the outer shell 25 is held by the holding pieces 28. At this time, one of the holding pieces 28a is held through the small hole 27. As a result, the vertical position of the valve member 24 is regulated by the fitting portion of the holding piece 28, and the front and rear positions are regulated by the tip of one holding piece 28a and the small hole 27. Ru. Therefore, the valve member 24 is always held at a constant position relative to the bottom body 6 and is temporarily fixed.

Next, the bottom cover 6a is placed over the bottom surface of the bottom body 6. At this time, the outer shell 25 of the valve member 24 is attached to the holding piece 28.
Since it is held by the bottom body 6, it does not move relative to the bottom body 6 and the mounting position does not change. In this state, insert the screw 32 into the screw hole of the overhanging part 31 of the bottom cover 6a and the wing part 26 of the valve member 24,
2, the bottom cover 6a and the valve member 24 are fixed to the bottom body 6 at the same time.

According to the present invention, when assembling the valve member 24 to the bottom body 6, the valve member 24 is attached to the holding piece 28.
In addition, the valve member 24 can be temporarily fixed by a simple operation of simply fitting it in using its elasticity, and the position of the valve member 24 can be accurately set by the temporary fixing. After that, the valve member 24 and the bottom cover 6a are fixed to the bottom body 6 with the screws 32 at the same time, so the fixing work is extremely simple, and the mounting position of the valve member is stable, and the lower opening of the inner container 7 is fixed. The valve member 24 can always be fixed at a constant position regardless of variations in the dimensions of the pipe 12. Therefore, a stable product with a uniform operability of the valve 17 and a uniform amount of liquid content can be obtained.

In the above embodiment, two holding pieces 28 are provided, but depending on the structure of the valve member 24,
One may be used, or three or more may be provided.

As described above, the present invention provides an excellent structure that is extremely easy to assemble, the mounting position of the valve member 24 is stable, and the valve member does not shift during use.
