 A pot fitted with a cup that also serves as a lid is mainly used as a portable pot. In this type of pot, an inner stopper is fitted in the opening of the container body, and a cup is covered above the inner stopper with the mouth facing downward, and the cup covers the outer surface of the inner stopper and the container body. The cup was detachably attached by screw fitting, bayonet fitting, or hinge lock device.

[0003]

[Problems to be solved by the device]

 In the above-mentioned cup mounting structure, there is the inconvenience that the screw has to be turned on and off about once in the case of screw fitting, and the bayonet fitting has to be turned by a certain angle to put in and take out. It was Further, the one using the hinge lock device has the inconvenience of having to operate the lock lever.

On the other hand, it is known that a magnet is attached to the peripheral edge of the opening of the container body and a magnet of different polarity is attached to the peripheral edge of the lower surface of the lid as a means of utilizing the attractive force of the magnet (actual flat 1-78). 553).

However, in this case, the magnets may be attracted to each other in a state where the center of the lid does not coincide with the center of the container body. Once attracted, a force is applied to align the centers. There are inconveniences such as the need to move the lid. In addition, since the magnets are attached to the peripheral edge of the opening of the container body and the peripheral edge of the lower surface of the lid, the size of the magnet becomes large, which is uneconomical.

Therefore, the present invention provides a cup which is simple in structure and can be attached and detached with one touch, because the operation such as the above-described rotation and the like such as the centering of the cup with respect to the container body is not required when attaching and detaching the cup. An object is to provide a liquid container provided with the liquid container.

【Example】

 The liquid container of the first embodiment shown in FIG. 1 is a portable pot, in which a cup 3 is detachably fitted in an opening 2 of a container body 1. The container body 1 is formed by fixing a lower part of an outer peripheral wall of a shoulder member 5 to an upper end part of a stainless steel vacuum double bottle 4, and the part from the upper end of the shoulder member 5 to the inner peripheral wall is the opening 2 described above. There is. A screw 6 is provided on the inner peripheral wall of the opening 2, and an inner plug 7 is detachably screwed into the opening 2. A packing 8 is attached to the inner plug 7, and the packing 8 is pressed against the stepped portion at the lower portion of the inner peripheral wall.

The upper end surface of the inner plug 7 is provided with two recesses 9 and 9 for picking, and a lower magnet set 12 is provided at the center of the upper surface of the pick 11 between the recesses 9 and 9. Mounted. The lower magnet set 12 has a magnet 14 housed in a plastic case 13 whose lower surface is open. The lower surfaces of the case 13 and the magnet 14 are attached to the upper surface of the knob 11 by adhesion.

The attachment of the magnet 14 is not limited to the above method, and the magnet 14 may be attached inside the upper surface of the knob 11 without using the case 13, for example.

A cup 3 having a downward drinking mouth is covered so as to cover the upper portion of the inner plug 7 and the outer peripheral surface of the shoulder member 5. The inner peripheral surface of the cup 3 approaches the outer peripheral surface of the shoulder member 5, and the drinking mouth rests on the step portion 15 formed at the lower end portion of the shoulder member 5.

With the drinking cup of the cup 3 resting on the step 15, the upper magnet set 16 is bonded to the bottom surface of the cup 3 at a position where the lower magnet set 12 and the center come close to or come into contact with each other. .. The upper magnet set 16 also has the magnet 18 housed in the case 17, but the polarity of the lower surface of the magnet 18 is different from that of the upper surface of the magnet 14 and exerts an attractive force on each other. The cup 3 is attached to the container body 1 by its suction force.

Instead of mounting the magnet 18 by the case 17, a recess may be formed in the bottom surface of the cup 3 and the magnet 18 may be housed in the recess.

When the cup 13 is removed, the cup 3 may be simply pulled away from the container body 1 by a force stronger than the attraction force between the magnets 14 and 18.

When returning the cup 3 to the original position, the drinking port of the cup 3 is dropped while being guided along the outer peripheral surface of the shoulder member 5. Then, the cup 3 receives the attraction force between the magnets 14 and 18, and at the same time, the drinking mouth is placed on the stepped portion 15 with the container body 1 and the center aligned.

The magnets 14 and 18 are preferably attached at the center of the product as shown in the figure, but the magnets 14 and 18 are not necessarily limited to this position and may be attached at any position above the inner plug 19. Alternatively, one of the magnets 14 and 18 may be used and the other may be made of a metal capable of adsorbing the magnet.

Next, a second embodiment shown in FIG. 2 is a pot in which an opening / closing valve 20 is incorporated in an inner plug 19, a valve hole 21 is provided at the lower end of the inner plug 19, and the valve hole 21 is opened / closed. The valve rod 23 of the valve body 22 is slidably inserted into a guide cylinder 24 provided in the center of the valve hole 21. Further, a spring 25 for urging the valve body 22 in the valve opening direction is attached.

A discharge port 26, which communicates with the valve hole 21 inside, is provided on the side surface of the upper end portion of the inner plug 19, and an operation member 27 having a tip inserted through the upper surface of the discharge port 26 is horizontally slid. It is provided to ride freely.

An inclined cam surface 28 is provided on the lower surface of the operation member 27, and the upper end of the valve rod 23 approaches the inclined cam surface 28. At the center of the upper surface of the operating member 27, the lower magnet set 12 similar to that of the first embodiment is attached at a position which coincides with the center of the container body 1 in the closed position.

Similarly to the case of the first embodiment, the cup 3 also has a drinking mouth mounted on the stepped portion 15 of the shoulder member 5, and a lower magnet set 12 and an upper magnet set 16 whose center coincides with the center are attached to the bottom surface of the cup 3. Be done.

In the pot of the second embodiment, the cup 3 is attached and detached in the same manner as in the first embodiment, but in the case of this embodiment, the operating member 27 is ejected as shown by the chain double-dashed line. When the valve body 22 is opened, that is, when it is pushed toward the outlet 26 side, the magnets 14 and 18 are not attracted, and the cup 3 is not set to the correct position. As a result, the user can be notified that the valve is open.

Further, as shown in FIG. 3, when the north and south poles are formed on the facing surfaces of the magnets 14 and 18, respectively, and those having different poles are made to face each other, the operating member 27 is in a valve closed state. At this time, the cup 3 is adsorbed and set in the correct position. However, when the operating member 27 is in the valve open state, the magnets 14 and 18 having the same polarities face each other and repel each other, so that the cup 3 is released. It is not set in the correct position. This allows the user to be notified that the valve is open.

Although the cup 3 is forcibly pulled apart by hand when the cup 3 is removed, the magnet 18 attached to the cup 3 is configured to be movable by sliding, rotating, etc. It is also possible to make the cup 3 easily come off by adsorbing the magnet provided on the same side with the same polarity before the movement and repulsing the same with the same polarity after the movement.
