Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a spout-equipped container for liquids, such as a pot or bottle, having a cylindrical spout.

Conventional technology and its problems Conventionally, liquid containers such as beverage pots made of synthetic resin molded products and glass bottles have been used.
As shown in Fig. 1, a cap 3' is attached to the opening at the center of the upper part of the container 1' by screwing means, etc., and a cylindrical spout 4' is attached to the shoulder 5' of the container 1' around the cap 3'. A small cap 7' for closing the spout 4' is connected, for example, to the base of the spout 4' by a connecting leg 10'.

In the case of such a container with a spout, it is desirable to have a small hole for ventilation in order to smoothly pour out liquid from the spout, but it is not recommended to have a ventilation hole that is always open and communicating. This type of container, which is used to store liquids such as drinking water, is not preferable because it has problems with liquid leakage and hygiene, especially when carried or tipped on its side. Therefore, in the above-mentioned container with a spout, it is desirable to provide a ventilation means for communication through the opening during pouring.

For example, in a bottle lid having a spout, the lid plate of the lid body that is fitted into the bottle spout is equipped with a ventilation means that communicates with the opening during pouring.
A top cover that covers the top of the spout in an openable and closable manner is rotatably and removably attached with an annular edge that fits into the filling port in the center of the lid body, and by rotating the top cover,
It has been proposed that the spout on the periphery of the lid body can be opened and closed, and that the ventilation holes on the periphery of the lid plate and the notch on the periphery of the top lid can be shifted or aligned. -11462).

However, in the case of the above-mentioned top lid rotation method, when the spout is closed, the peripheral part of the top lid only covers and blocks the top surface of the spout and ventilation hole in the lid body, and the state is completely sealed. is difficult to obtain, so if the bottle falls on its side,
There is a risk that the internal liquid may leak between the lid body and the top lid through the spout and the ventilation hole, and further leak to the outside. In other words, although this type of top lid rotating type can be used for lids on bottles with relatively small diameters, it is also used for relatively wide-mouth containers for storing drinking water, etc., especially cylindrical containers that are sometimes used for portable use. Containers with spouts cannot be used due to hygienic problems such as liquid leakage when tipped over.

In view of the above, the present invention utilizes the attachment of a closing member to the spout in a container having a cylindrical spout so that the ventilation hole can be opened and closed by rotation of the closing member, thereby dispensing liquid. In addition, when the spout is closed, the spout and the ventilation hole can be reliably maintained in a completely sealed state, and there is no risk of liquid leakage even when the spout is tipped on its side, making it suitable for portable use. The purpose is to provide a container with a spout for drinking water, etc.

Means for Solving the Problems The present invention, which solves the above problems, is a container in which a cap is attached to the upper opening of the container, and a cylindrical spout is provided on the periphery of the cap or on the shoulder of the container. A closure member for the spout is attached to the center of the cap, and the closure member is made of an elastic material such as rubber and includes a closure that can be freely fitted to the spout and a closure member attached to the center of the cap. The fitting shaft portion has a fitting shaft portion for the mounting hole provided at both ends, and the fitting shaft portion has a slightly larger diameter than the mounting hole, and a circumferential recess corresponding to the peripheral edge of the mounting hole is formed in a part of the fitting shaft portion. A constricted portion formed by a groove is provided, and the constricted portion of the fitting shaft portion is fitted into the mounting hole and is rotatably attached, and the fitting shaft portion of the closing member and the cap are provided with a constricted portion for attaching the cap. The periphery of the hole is characterized in that a notch is provided on the peripheral edge of the hole so that when the closing member is rotated through a predetermined angle from the spout closed position, the notch coincides with each other and becomes a small ventilation hole.

Effect According to the present invention having the above-described configuration, in the closed state where the plug of the closing member fits into the spout,
The notch on the periphery of the mounting hole in the center of the cap is located at a position different from the notch on the fitting shaft of the closing member, and is blocked by the large diameter portions above and below the circumferential groove of the fitting shaft. Also, since the notch in the fitting shaft is also covered by the peripheral edge of the mounting hole, a sealed state is maintained. In particular, since the closing member is made of an elastic material, the fitting shaft portion elastically fits and tightly contacts the periphery of the mounting hole of the cap due to the elasticity of the material, thereby reliably achieving the sealing action. The closure can also be tightly fitted to the spout by elastic force. Therefore, even if the container falls on its side, there is no risk of the internal liquid leaking out from the fitting portion.

When pouring out the liquid inside, the plug fitted to the spout is released using its elasticity to open the spout, and the plug is moved around the fitting shaft with its elasticity. By rotating the cap at a required angle against the force of fitting, the notch on the cap side and the notch on the fitting shaft side can be aligned and communicated with the opening. If the dispensing operation is performed in this state, The above-mentioned notch portion serves as a small ventilation hole, allowing the liquid inside to be easily poured out.

Fitting, detaching, and rotating operations of the closing member to the spout can be easily performed by utilizing the elasticity of the material of the closing member.

Embodiment Next, an embodiment of the present invention will be described based on the drawings.
1 is a container made of synthetic resin or glass molded by blow molding or other means, and a cap 3 is attached to an opening 2 at the top by means of screwing with an internal screw or fitting means using elasticity as shown in the figure. It is provided in a removable manner. Positioning of a stopper or the like on the cap 3 side and the container 1 side that are engaged with each other so that the cap 3 is fixedly attached to the container 1 at a fixed position in a certain direction in relation to the spout described later. It is better to provide means for Reference numeral 4 designates a spout provided on the shoulder 5 of the container 1, and as shown in the figure, the spout protrudes so that its tip is approximately at the same height as the top surface of the cap 3. Although not shown, it is also possible to provide a spout around the cap 3. In this case, a means for positioning the cap 3 is not required, and the entire upper part of the container 1 does not have an open shoulder. This method can also be applied to containers of this type.

Reference numeral 6 denotes a closing member for the spout 4, which is attached to the center of the cap 3 described above. This closing member 6 is made of an elastic material such as rubber, and includes a closing body 7 that can be freely fitted to the spout 4, and a shaft portion 9 that fits into a mounting hole 8 provided in the center of the cap 3.
In the case of the figure, a plug-shaped plug 7 and a fitting shaft portion 9 are provided at both ends of one side (lower surface) of a band-like connecting portion 10 to protrude. It becomes. The fitting shaft portion 9 of the closing member 6 is formed to have a diameter slightly larger than the diameter of the mounting hole 8 in the center of the cap 3, and has a diameter corresponding to the peripheral edge 11 of the mounting hole 8 at the central portion in the axial direction. Mounting hole 8 formed by circumferential groove 12
The constricted portion 13 having approximately the same diameter as the upper and lower large diameter portions 9a, 9
b. The closing member 6 is attached to the circumferential groove 12 of the fitting shaft 9 with respect to the mounting hole 8 at the center of the cap.
The constricted portion 13 is also fitted so as to fit together, and is rotatably attached around the fitting shaft portion 9. Further, the circumferential groove 12 of the fitting shaft portion 9
The outer periphery of the upper and lower large diameter portions 9a, 9b and the peripheral edge 11 of the mounting hole 8 are aligned with each other for ventilation when the closing member 6 is rotated by a required angle from the position where the spout is closed by the closing body 7. Cutouts 14 and 15 serving as small holes are provided. If the positions of the notch 14 on the fitting shaft 9 side and the notch 15 on the cap 3 side are shifted by a required angle (for example, 90 degrees) when the closing member 6 is in the spout closed state, It may be located anywhere on the fitting shaft 9 and the peripheral edge 11, but in the illustrated embodiment, the peripheral edge 11 of the mounting hole 8 on the cap 3 side has a hole in the direction perpendicular to the direction facing the spout 4. Notches 15, 15 are provided on both sides, respectively.
On the other hand, the fitting shaft portion 9 is provided with a notch 14 at one location on the side of the spout 4 facing the closing body 7, and the notch 14 is provided at one location on the side of the spout 4 facing the closing body 7. , 15 can be matched. Further, stoppers 16, 16 are provided on the upper surface of the cap 3 to prevent the closing member 6 from rotating around a required angle, so that the closing member 6 is stopped at a predetermined rotational position.

Note that if the fitting shaft portion 9 has a large diameter portion 9a also at the upper part of the circumferential groove 12, the connecting portion 10 will not come into close contact with the upper surface of the cap 3, so that the notch 14 will be located on the side facing the closure 7. Even if the notches 14 and 15 match, ventilation will not be obstructed. The notches 14 and 15, which serve as small ventilation holes, may be not only vertical grooves as shown in the figure, but also penetrating holes.

As the above-mentioned closing member 6, the closing body 7 for the spout 4 can be formed into a cap shape, and the connecting part 10 connecting the closing body 7 and the fitting shaft part 9 can be formed into a band-like shape as shown in the figure. In addition, it is also possible to form it into a plate shape or a round bar shape with a width narrower than the diameter of the fitting shaft portion 9 as long as it has appropriate elasticity.

When using the container constructed as described above, after removing the cap 3 and storing a liquid such as drinking water through the upper opening 2 of the container 1, the cap 3 is attached to the opening 2 and the spout 4 is closed. Closing member 6
It is closed by fitting the plug 7. At this time, the notch 15 formed on the peripheral edge 11 of the mounting hole 8 in the center of the cap 3 and the notch 14 formed on the fitting shaft 9 of the closing member 6 for the mounting hole 8 are in shifted positions.
Therefore, the notch 15 is closed by the upper and lower large diameter portions 9a and 9b of the circumferential groove 12 of the fitting shaft portion 9, and the notch 14
is closed at the peripheral edge 11 and maintains a sealed state. In particular, since the closing member 6 is made of an elastic material, the fitting shaft portion 9 elastically fits tightly against the cap 3 due to the elasticity of the material, thereby reliably achieving the front sealing action. Body 7 also spout 4
A tight fit can be achieved by the elastic force. Therefore, even if the container falls on its side, there is no risk of the internal liquid leaking out from the fitting portion.

When pouring out the liquid inside, the spout 4 is opened by removing the plug 7 fitted to the spout 4, and the plug 6 is moved to the fitting shaft 9.
The notch 15 on the cap 3 side and the notch 14 on the fitting shaft 9 side may be aligned by rotating the cap 3 by a required angle against the elastic fitting force. , 15 can be opened and communicated with each other, and this becomes a small ventilation hole. If the container 1 is tilted in this manner and the pouring operation is performed, the notches 14, 15
Air flows in through the small ventilation holes to promote a smooth flow of fluid, and even if the diameter of the spout 4 is small, the fluid can be poured out easily. In addition, at this time, the closing member 6 moves so that the closing body 7 moves away from the position of the spout 4 and faces to the side.Moreover, due to the elasticity of the material, the closing member 6 maintains the state facing to the side and pours out. It does not interfere with operation.

After pouring, the closing member 6 is rotated back to its original position and the closing body 7 is fitted into the spout 4, and the notches 14 and 15, which will become ventilation holes, are shifted again, preventing ventilation. The container is kept in a sealed state.

Effects of the Invention As described above, according to the present invention, the notch that becomes the small ventilation hole can be opened and closed by rotating the closing member by using the attachment of the closing member to the spout, and when pouring out liquid. The ventilation holes formed by the notches can be made to communicate with each other, making it easy to pour out liquid even if the spout has a relatively small diameter.Furthermore, when the spout is closed, the notch can be kept in a sealed state, and the closing member can be closed. The fitting part for installation and the spout can be reliably held in a sealed state, and the inside of the container can be almost completely sealed, so there is no risk of liquid leaking if the container is tipped over, and the stored liquid can be stored in a sanitary manner. Can be protected.
In addition, due to the elasticity of the material of the closing member, even if the container diameter is relatively large or the spout is protruding into a cylindrical shape, the fitting of the closure to the spout, the removal operation, and the rotation of the spout can be prevented. Movement operations can be performed easily without any problems. Therefore, the present invention is highly suitable for use as a portable beverage pot or other container with a spout that may be used in a portable manner. It also looks good and has excellent design effects.
