Description

[Detailed Description of the Invention] This invention relates to a plug device provided at the spout of a water bottle.

Water bottles are required to be easy to handle, but because they are often carried in bags, backpacks, etc., a reliable stopper device that does not leak water is particularly required.

In order to meet both of these requirements, plug devices with various structures have already been proposed.

However, there are some aspects of the above requirements that cannot be met, and in order to overcome this, the number of parts is large and the structure is complicated, resulting in an increase in cost and also being inconvenient for cleaning etc. .

Conventionally, the structure was relatively simple and the handling was easy.
For example, the one shown in FIG. 1 is known.

In this device, a stopper C is screwed onto the inner periphery of a cylindrical spout B integrally formed on the shoulder part A of the water bottle, and the stopper C is attached to the hemispherical bottom part C.
1, and the lower end opening b of the spout B.
1, a valve backing E is provided at the lower end of the bottom portion C1 that protrudes downward from the lower end opening b1 to open and close the lower end opening b1.
A communication hole F is provided just above the fitting portion of the valve backing E, and by rotating and moving the plug C upward, the valve backing E is inserted into the lower end opening b1 of the spout B. By pressing it to the closed state and moving it downward in the opposite direction, the valve backing E is separated from the lower end opening b1 of the spout B, and the valve backing E is brought into the open state.

Therefore, the operation of the stopper C is opposite to the frame type that Akitatsu is accustomed to, that is, the open state when the stopper moves upward, and the closed state when the stopper moves downward, so it cannot be used. In addition to being confused or having a sense of discomfort,
In some cases, it is easy to misidentify the closed and open states, leading to failures such as attempting to pour the contents when they are not, or handling them as if they were closed, causing the contents to leak. It is.

Also, in an attempt to eliminate some of the confusion in the above operations,
The threading of the stopper C into the spout B is a left-hand thread, and as we are accustomed to, when the stopper C is turned to the left, it opens and when it is turned to the right, it closes. However, the relationship between the vertical movement of the plug C at each rotation is still reversed, and on the contrary, the relationship between the vertical movement of the plug C and the direction of rotation of the plug C is reversed.
Since the relationship between the vertical movement direction of the stopper and the open/closed state of the stopper is reversed from the normal case, it is more likely to be misrecognized.

In addition, the plug C is moved upward, that is, it is in the closed state in a protruding state, but if the cap G applied to the shoulder A is removed or the cap F is not applied, the plug C C
Especially when the head collides with or gets caught in another object.

The external force at this time generally acts in the direction of pushing the plug C,
In addition, as a result, a rotational force is generated in the downward direction of the stopper C, causing the stopper C to open by itself, and the stability of the closed state is poor, and it may open naturally due to vibrations while being carried. There is a tendency for the lid to close, and a reliable closing function cannot be expected.

Furthermore, the plug C is fitted onto the inner periphery of the spout B, and only the tip spout B2 protrudes from the spout B, which is too small to be operated by holding that part. ,
This is unfavorable from a hygienic point of view, and an operating ring H that covers the outer periphery of the spout B as shown in the figure is attached to the exposed part of the stopper C so as to rotate together, and the operating ring H is used to operate the spout B. Extra parts must be provided just for operation.

Then, the plug body C is the lower end opening hole b1 of the valve backing E.
It is difficult to remove the valve backing E because it gets caught on the valve body, and it is also difficult to remove the valve backing E and clean every corner of the valve body C by removing it.

In view of the above-mentioned points, the object of this invention is to provide a water bottle stopper device that has a simple structure, has an excellent closing function, and is easy to operate and disassemble and clean.

To explain the embodiment shown in FIGS. 2 to 4, 1 is a water bottle main body, which is entirely made of transparent synthetic resin such as polypropylene, and is integrated with a cylindrical spout 2 that projects upward. Blow molded.

The water bottle body 1 is covered with a two-part outer case 3, and the case 3
A two-part heat insulating wall 4 is interposed between the water bottle body 1 and the water bottle body 1.

5 is a decorative band that covers the seam of the two-part outer case 3.

The case 3 has a vertically long internal capacity display window 7 on one side of which a transparent plate 6 is fitted.

8 is a bottom coupling plate of the case 3, and 9 is a mouth coupling ring of the case 3.

The cylindrical spout 2 of the water bottle main body 1 is formed in a step-like manner from the shoulder of the main body 1 and protrudes from the upper opening 10 of the case 3, and a ring retainer 11 is screwed onto the upper outer periphery of the maximum diameter root portion 2a. 12, and a cylindrical stopper 13 is screwed 14 into the outer periphery of the first step portion 2b on the root portion 2a from the distal end thereof in a right-handed screw shape.

This cylindrical plug body 13 has a valve body part 13a located on its central axis and in contact with and away from the tip spout 15 of the cylindrical spout 2 in the axial direction, via a radial arm 13b extending around the valve body part 13a, It is held rotatably.

As a result, the cylindrical plug body 13 is rotated in the loosening direction or the tightening direction and moves upward or downward, releasing or pressing the valve body portion 13a against the pouring field 15, as shown in FIG. Open the spout 15 or close it as shown in FIG.

The radial arms 13b on the outer periphery of the valve body 13a are continuous with an outer annular body 13C, and this outer annular body 13C is formed by a liquid injection guide part 13d whose diameter gradually decreases at the tip of the cylindrical plug 13. A communication portion 13f is formed between the radial arms 13b and the upper and lower portions of the valve body portion 13a of the cylindrical stopper 13, which is received between the step portion 13e and the edge of the spout 150, and is formed between the radial arms 13b. 15 is opened, the contents flow out from the spout 15 into the cylindrical stopper 13, and then are poured out from the liquid injection guide part 13d through the communication part 13f.

In addition, since the valve body part 13a can also move up and down with respect to the cylindrical plug body 13, the valve body part 1 can be moved by rotating the plug body 13 toward the slack side.
Even if the pressure of 3a is released, the valve body 13a does not immediately open the spout 15, and may be pushed by the liquid that is about to flow out when the water bottle body 1 is tilted, or the valve body 13a may close the spout 15. It moves automatically when facing downward,
Open spout 15.

Of course, the valve body part 13a can be held so as not to move in the axial direction relative to the cylindrical plug body 13, and can be moved together with the upper and lower parts of the plug body 13 to immediately open and close the spout 15.

The cylindrical spout 2 has an annular groove 16 formed on the outer periphery of the second stage portion 2C, and a backing 17 that connects to the inner periphery of the cylindrical stopper 13 is attached to the groove 16. Prevents leakage of contents.

Further, a backing 18 is attached to a portion of the valve body 13ay that is pressed against the edge of the spout 150, so that the spout 15 can be reliably closed.

Since the valve body portion 13a is rotatable relative to the cylindrical stopper 13, when the cylindrical stopper 13 is rotated in the cottoning direction and presses the backing 18 against the rim of the spout 15, Alternatively, when gradually releasing the pressure of the backing 18 by rotating it toward the slack side, the valve body The part 13a receives the contact resistance and slides against the cylindrical plug 13 and stops together with the backing 18,
This prevents the backing 18 from sliding against the spout 15 and from twisting thereby.

Reference numeral 19 denotes a cap that also serves as a cap, and its lower end is elastically fitted into an annular groove 20 formed on the outer periphery of the ring presser 11, so that it can be attached and detached.

The spout 15 can be opened and closed by the valve body 13a simply by rotating the cylindrical stopper 13 in the loosening direction or the tightening direction, so the operation is simple and the cylindrical stopper 13 is easy to remove. The pouring spout 2 and the stopper 13 can be easily cleaned from every corner.

When dispensing the liquid content, the valve body 13a is located at the center of the liquid and at first glance it seems to be in the way, but the outlet passage is enlarged near the valve body 13a and the force of the liquid is damped. After the liquid is poured, the flow diameter is narrowed and poured by the liquid injection guide part 13d, which not only prevents the liquid from scattering to the surroundings, but also facilitates quiet and stable pouring in a laminar flow state. It is easy to receive the liquid into other containers.

Note that a knurling pattern 21 is provided on the outer periphery of the cylindrical stopper 13 to facilitate rotational operation.

The communication part 13f around the valve body part 13a is the communication part 13f around the valve body part 13a.
It may be a through hole that is appropriately opened in itself.

In the embodiment shown in FIG. 5, the valve body portion 13a is
3, and a liquid injection guide portion 13d is a separate member that is elastically fitted to the cylindrical plug body 13, and 13g is its elastic engagement portion.

In this case, the valve body part 13a is held by integral molding, so there is no need to assemble it, and the liquid injection guide part 13d
It is sufficient to simply fit the

Other structures are the same as those in the previous embodiment.

In the embodiment shown in FIG. 6, a hollow protrusion 22 as shown by the imaginary line is integrally blow-molded on the outer periphery of the distal end of the closed spout 2, and by cutting it out, a horizontal spout can be created. A plurality of valve bodies 15 are opened, and the inner circumferential stepped part formed by the liquid injection guide part 13d of the cylindrical plug body 13 is connected to the annular valve body part 13a.
By moving the spout 15 of the spout 2 toward and away from the opening portion of the spout 15 in the direction of the central axis of the spout 2, the spout 15 is communicated with the outside from the liquid injection guide portion 13d, or the communication is made. The spout 15 is opened and closed indirectly by cutting off the spout 15, further simplifying the structure.

The spout 2 in this embodiment can be easily formed by integrally blow molding the shoulder part of the water bottle body 1 when the shoulder part is separated from other parts. The body can be made of any material other than synthetic resin, such as aluminum.

Such a water bottle main body 1 with a split body and shoulder is easy to clean inside, and it is convenient to remove the body from the cover and freeze the liquid inside.

According to this invention, the structure is as simple as screwing a cylindrical stopper equipped with an opening/closing valve body for the tip spout of the spout onto the outer periphery of the spout that is integrally blow-molded on the water bottle main body side. Moreover, the cylindrical stopper is a normal screw, that is, a right-hand screw,
Rotation in the tightening direction causes the cylindrical plug to move downward and close, and rotation in the loosening direction causes the cylindrical plug to move upward and open. It is easy to use and does not have a Japanese feel, and also eliminates the inconvenience caused by misunderstanding the closed and open states.

In addition, even if the bulge-shaped stopper hits another object in the closed state, it will not open, ensuring a reliable closing function.
