DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottle containing soy sauce or the like therein.

[0002]

2. Description of the Related Art Conventionally, as containers for soy sauce, mirin or the like, a bottle body having a substantially cylindrical mouth, an inner plug attached to the mouth of the bottle body, and a cap detachably attached to the inner stopper. Are known. The inner stopper is provided with a spout for pouring contents such as soy sauce outside the bottle body.

[0003] When a large amount of the contents in the bottle body is poured from the spout at once, a so-called pulsation may occur in which the outflow of the contents periodically decreases or increases. If pulsation occurs when the contents are poured, the contents may scatter and adhere to clothes or the like. Since the pulsation occurs when a large amount of the content is to be poured compared to the diameter of the spout, it is conceivable to increase the diameter of the spout to prevent the pulsation. However, if the diameter of the spout is too large, it is difficult to adjust the outflow amount of the contents such that a large amount of the contents is erroneously poured even when only a small amount of the contents is desired. Further, in an inner plug having a spout that makes it easy to smoothly pour the contents while adjusting the amount of outflow, the structure of a cap attached to the inner plug to securely close the spout may be complicated. There is a disadvantage that there is.

[0004]

DISCLOSURE OF THE INVENTION The present invention solves such a disadvantage, and has a simple structure with a spout provided with a spout capable of pouring contents while smoothly adjusting the outflow amount without pulsation. Still another object of the present invention is to provide a bottle body having a cap that reliably closes a spout when attached to an inner plug.

[0005]

According to the present invention, there is provided a bottle body having a substantially cylindrical mouth, a bottle body attached to the mouth, and the inside and outside of the bottle body. A spout having a spout that communicates with the spout, and a cap that is detachably attached to the spigot and has a cap that closes the spout, wherein the spout faces the radial direction of the spigot. The caps are provided at two positions on the outer peripheral surface of the side wall so as to have substantially different diameters, and the closing portions are provided at two positions on the inner peripheral surface of the side wall facing in the radial direction of the cap so as to protrude substantially spherically. It is characterized by having been done.

[0006] According to the inner plug having such a configuration, when the content is poured out from one spout, the other spout serves as an air intake, so that pulsation does not occur. In addition, when a large amount of content is poured, a large-diameter spout is used, and when a small amount is poured, a small-diameter spout is used to easily adjust the outflow amount of the content.

When the cap is fitted into the inner plug and turned in the horizontal direction, the substantially spherical closing portion smoothly closes the spout while gradually increasing the contact area with the tip of the substantially cylindrical spout. Can be. In addition, the spout is provided at a position symmetrical in the radial direction of the inner plug, and the closing portion is provided on the side wall portion facing the radial direction of the cap, so one spout is closed by one of the closing portions. The other spout is then reliably closed by the other of the closures. The structure of the cap for closing the spout is as simple as providing a substantially spherical closing portion protruding at two positions on the inner peripheral surface of the side wall facing in the radial direction.

In the bottle having the above-mentioned structure, for example, when the cap is opaque, it may be difficult to confirm whether or not the spout of the inner plug is closed by the closing portion of the cap. If the spout is not closed, the contents may be deteriorated by contacting the outside air, or the contents may be unexpectedly spilled when the bottle is knocked down.

Therefore, in order to prevent such a situation, the side wall of the inner plug is continuously cut off from a predetermined portion of the outer peripheral surface thereof along a predetermined circumferential direction of the inner plug and formed over a predetermined distance. A groove is provided, and when the cap is fitted into the inner plug, a protrusion is provided on the inner peripheral surface of a side wall of the inner plug which is substantially at the same height as the groove, and the cap is attached to the inner plug. When the fitting is rotated in the predetermined circumferential direction, and the projection is brought into contact with the end of the groove, the two closing portions of the cap close the two spouts of the inner plug, and the projection is closed. The two closing portions of the cap are separated from the two spouts of the inner plug when the cap is separated from the end of the groove by at least the predetermined distance.

In the bottle body having such a configuration, when the cap is fitted into the inner plug and rotated in a predetermined circumferential direction, and the projection of the cap is brought into contact with the end of the groove of the inner plug, two spouts of the inner plug are provided. Is securely closed by the two closing portions of the cap. Therefore, the user can easily confirm that the two spouts of the inner plug are closed by the two closing portions of the cap by responding when the protrusion of the cap comes into contact with the end of the groove of the inner plug. . In addition, when a force is applied to the cap in the vertical direction, the protrusion contacts the side wall of the groove, so that the cap is prevented from easily coming off the inner plug.

When the cap is rotated by a predetermined distance in a direction opposite to the predetermined circumferential direction from a state in which the projecting portion is in contact with the end of the groove, the two closing portions are separated from the two spouts, respectively. Further, since the groove is provided over the predetermined distance, the protruding portion comes off the groove at this time. Therefore, when an upward force is applied to the cap, the cap can be easily removed from the inner plug without bringing the closed portion into contact with the spout of the inner plug and without hooking the protruding portion into the groove of the inner plug. be able to.
