Description

The present invention relates to a beverage container, and more particularly to a beverage container that enables or prevents the liquid in the container body from being discharged to the outside by opening and closing a valve mechanism provided on the stopper.

The tabletop pot, which holds the handle to pour beverages such as coffee and tea into the cup, opens and closes the valve mechanism provided in the liquid passage of the stopper by operating the operation lever, and the liquid content of the container body is poured from the spout. It is designed to be able to discharge to the outside or to prevent it. In a tabletop pot, if the valve is opened while the contents are hot and the internal vapor pressure is high, hot steam may spurt out from the spout and stain the surroundings or hang on the face. As a countermeasure against this, conventionally, when the pressure relief passage and the auxiliary valve body that opens and closes the pressure relief passage are incorporated in the main valve body that opens and closes the liquid passage of the valve mechanism, and the valve is opened when the internal vapor pressure is high. At first, only the auxiliary valve body is opened to allow high-pressure steam to escape into the plug through the depressurization passage, and then the main valve body is opened.

For example, in the tabletop pot described in Patent No. 391327, a valve rod with a flap (top) is slidably inserted vertically into a guide cylinder provided inside the plug, and is interposed between the upper surface of the guide cylinder and the lower surface of the flap. The valve rod is urged upward by the compression coil spring of 1, and the valve body (main valve body) that opens and closes the liquid passage is slidably inserted up and down under the valve rod, and is inserted between the valve rod and the lower surface side of the guide cylinder. While the valve body (main valve body) is urged downward by the second compression coil spring mounted, the lower end of the valve body (main valve body) on the lower surface side of the valve stem is bulged in a disk shape to subordinate. The valve body is used, and the gap between the valve rod and the valve body is used as a pressure relief passage.

When hot beverage is injected into the container body and the pressure inside the container body is increased by steam, when the operation lever is rotated, the valve body (main valve body) becomes a stopper due to the pressure inside the container. While being pressed against the lower end of the lower cylinder and blocking the liquid passage, the sub-valve body separates from the lower surface of the valve body (main valve body) due to the descent of the valve rod, the pressure release passage is opened, and high-pressure steam is plugged. Escape into the body. Along with this, the pressure inside the container body decreases, the valve body (main valve body) lowers downward due to the urging force of the second compression coil spring, the valve body (main valve body) opens, and the liquid passage is opened. .. As a result, even if the valve body (main valve body) is opened, there is no risk of high-pressure steam being discharged from the spout, and safety is increased.

However, in the conventional depressurization structure described above, the first compression coil spring that constantly urges the valve stem upward and the second compression coil spring that constantly urges the valve body (main valve body) downward are moved up and down. Since the configuration is arranged in two stages, there is a problem that the entire valve mechanism inevitably becomes large.
In addition, when the valve body (main valve body) is opened and the beverage liquid is poured into the cup, the area around the second compression coil spring on the lower side is immersed in the beverage, so that it is easy to get dirty and it takes time to clean. was there.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a beverage container capable of miniaturizing a valve mechanism.

A slight gap (pressure relief passage, which will be described later) is opened in the through hole 523 formed in the vertical direction, and the spring is movably inserted in the vertical direction. A vertically long valve rod 525 provided with a sub-valve body 524, and a coma portion 526 detachably attached or fixedly attached near the upper end portion of the inner bottom surface 312 of the valve rods 525. , A first coil spring 528 interposed between the ring-shaped first spring seat 527 formed near the outer periphery of the lower surface of the top portion 526 and the upper surface of the middle bottom surface 312 surrounding the guide portion 520. On the inner diameter side of the first coil spring 528, between the ring-shaped second spring seat 529 formed near the inner circumference of the lower surface of the coma portion 526 and the upper end surface 530 of the shaft portion 521 of the main valve body 522. It is composed of a second coil spring 531 interposed therebetween.

The first coil spring 528 of the valve mechanism 32 is always in a compressed state, and has a function of urging the top portion 526 upward together with the valve rod 525. The second coil spring 531 is in an uncompressed state when the valve rod 525 is returned upward (note that when the valve rod 525 is returned upward, it may be in a state of being compressed weaker than the first coil spring 528. ). The second coil spring 531 has a function of downwardly urging the main valve body 522 including the shaft portion 521 to the coma portion 526 mounted on the valve rod 525 when it is in the compressed state. A ring-shaped packing 533 that stops water in close contact with the hole wall 532 of the guide portion 520 is fitted on the outer periphery of the shaft portion 521 near the upper end. The lower end of the through hole 523 is a large-diameter hole 534 that bulges in the radial direction, and when the valve rod 525 is in a state of being returned upward, the auxiliary valve body 524 at the lower end of the valve rod 525 has a large-diameter hole 534. It is freely inserted and removed inside. A cap-shaped packing 536 that stops water in close contact with the hole wall 535 of the large-diameter hole portion 534 is fitted on the outer surface of the auxiliary valve body 524. The gap between the valve stem 525 and the through hole 523 forms the pressure relief passage 537.

The upper member 3b incorporates an operation lever 34 and a detachable lever 35 in the upper main body 33. The upper main body 33 includes a top plate portion 331 and a peripheral side surface 332, and the peripheral side surface 332 has a shape that is substantially tightly fitted to the peripheral side surface 311 of the lower main body 31, and is an inner infestation hole facing the outer infestation hole 315 at the time of fitting. A 333 is provided, and an operation recess 334 of the detachable lever 35 is formed on the left and right on the line provided with the inner indentation hole 333 in the top plate portion 331.
The operation lever 34 has an operation portion 341 whose tip portion is pivotally connected to the upper main body 33 to be rotatable, and which protrudes outward from the top plate portion 331 on the side opposite to the formation position of the upper liquid passage 313, and a rotation operation. It is provided with a pressing plate portion 342 that presses the top of the valve rod 525 to open the valve, and a blocking plate portion 343 that advances and retracts into the operating range of the attachment / detachment lever 35 with the rotation operation. The pressing plate portion 342 is constantly urged upward by the valve rod 525 urged upward by the first coil spring 528.

The attachment / detachment lever 35 is an L-shaped locking portion 351 having a horizontal plate portion protruding from the outer protrusion / exit hole 315 on the side of the plug body, and the standing portion protruding upward in the operating recess 334 to form an operation portion 352. Further, a compression coil spring 353 for a lever that urges the attachment / detachment lever 35 in the outward direction in the left-right direction is attached, and when the attachment / detachment lever 35 retracts by a predetermined distance (movement toward the center of the plug body), the operation lever 34 A collision portion 354 is provided so as to advance into the operating range of the blocking plate portion 343.

Before supplying the beverage, the shoulder member 2 is fixed to the container body 1, the beverage is poured into the container body 1 with the stopper body 3 removed from the shoulder member 2, and then the stopper body 3 is attached to the shoulder member 2. Attach to. At this time, the directions of the outlet 401 of the upper liquid passage 313 and the spout 22 are matched. In the first coil spring 528 and the second coil spring 531 when the operating lever 34 is not pressed by a finger, the main valve body 522 moves upward through the top portion 526 and the valve rod 525 by the first coil spring 528 in the compressed state. By being urged, the main valve body 522 returns upward, and is in close contact with the packing 314 to block the lower liquid passage 317, and the auxiliary valve body 524 closes the pressure release passage 537.

When the beverage in the container 1 is hot, the vapor pressure in the container 1 is high, and when the operation lever 34 is pressed with a finger to pour the beverage, if the main valve body 522 suddenly opens, the beverage is poured. Hot steam may spurt out from the mouth 22 to pollute the surroundings or hang on the face.
In this embodiment, when the steam pressure in the container body 1 is high, the main valve body 522 is strongly pressed upward by the steam pressure, and the upward urging force of the first coil spring 528 to pour the beverage. When the operation lever 34 is started to be pressed with a finger against the above, the auxiliary valve body 524 is lowered together with the valve rod 525 while the main valve body 522 is initially returned upward, and the pressure release passage 537 is opened. As a result, the high-pressure steam in the container body 1 escapes into the plug body through the pressure relief passage 537 and is pressure-removed (see arrow e in FIG. 4). When the vapor pressure drops and the force that presses the main valve body 522 upward weakens, the compression of the second coil spring 531 accompanying the pressing of the operating lever 34 increases the downward urging force on the shaft portion 521, and the main valve body 522 Move down. As a result, the space between the main valve body 522 and the lower opening end 316 of the peripheral side surface 311 is opened, and the lower liquid passage 317 is opened. Beverages in the container 1 can be poured into a cup (not shown) via a liquid passage including a lower liquid passage 317 and an upper liquid passage 313 and a spout 22 (see arrow f in FIG. 5).
When the pressing of the operating lever 34 is released, the valve rod 525 returns upward by the restoring force of the compressed first coil spring 528, and in conjunction with this, the operating portion 341 of the operating lever 34 rotates and returns upward. At this time, the main valve body 522 returns upward, closes the lower opening end 316, and returns to a state in which the lower liquid passage 317 and the inside of the container body 1 are blocked.

When the beverage container is used, the stopper 3 is in an assembled state in which the upper member 3b is fitted and mounted on the lower member 3a. In this state, the locking portion 351 of the detachable lever 35 is urged by the compression coil spring 353 for the lever. The lower member 3a and the upper member 3b are integrated with each other by penetrating the inner indentation hole 333 and the outer infestation hole 315 and projecting outward in the radial direction. The attachment / detachment of the stopper 3 to / from the shoulder member 2 is performed by retracting the locking portion 351 by operating the attachment / detachment lever 35 (retracting operation toward the center of the stopper against the urging force of the lever compression coil spring 353) and the attachment / detachment lever 35. The locking portion 351 protrudes outward in the radial direction due to the urging force of the lever compression coil spring 353 accompanying the release of the shoulder member 2, so that the shoulder member 2 is locked and released from the locking recess 24.

By providing the blocking plate portion 343 on the operation lever 34, in a state where the tip of the locking portion 351 of the attachment / detachment lever 35 is located in the outer indentation hole 315, even if the attachment / detachment lever 35 is to be retracted, the collision portion 354 will occur. Since the operation lever 34 collides with the blocking plate portion 343 and the retracting operation is prevented, when the operating lever 34 is lifted by the urging force of the first coil spring 528, the operation of the attachment / detachment lever 35 is performed from the peripheral side surface 311 of the locking portion 351. The tip of the locking portion 351 does not come out from the outer infestation hole 315 to the back due to the limitation of the protruding / non-protruding range (see FIGS. 6 and 7).

After removing the plug 3 from the shoulder member 2, the operation lever 34 is pushed down to release the blocking plate portion 343 from the operating range of the collision portion 354, and then the detachable lever 35 is retracted toward the center of the plug 3. Since the blocking plate portion 343 does not interfere with the locking portion 351, the tip of the locking portion 351 moves to the back of the outer haunting hole 315 and escapes from the outer hauling hole 315 (see FIG. 8), and in this state, the lower member 3a is pulled downward. , The fitting and mounting with the upper member 3b is released, and the lower member 3a and the upper member 3b are separated (see FIGS. 9 and 10).
Therefore, the attachment / detachment of the plug 3 to / from the shoulder member 2 can be performed in a state where the lower member 3a and the upper member 3b are integrated by operating only the attachment / detachment lever 35 without operating the operation lever 34. On the other hand, when cleaning the inside of the plug 3, the plug 3 can be easily disassembled into the lower member 3a and the upper member 3b by retracting the attachment / detachment lever 35 with the operation lever 34 lowered. In the state where the operation lever 34 is lowered and the attachment / detachment lever 35 is retracted, the upper member 3b is fitted to the lower member 3a, the inner appearance hole 333 and the outer appearance hole 315 are aligned, and the attachment / detachment lever 35 is released and engaged. The stop portion 351 can be easily assembled by penetrating the inner indentation hole 333 and the outer infestation hole 315 and projecting outward in the radial direction by the urging force of the compression coil spring 353 for the lever.

The upper liquid passage 313 opens an upper surface portion that is exposed upward when the upper member 3b is separated after the plug 3 is disassembled, and the upper liquid passage 313 that is easily contaminated by beverages is largely exposed to the outside. It is formed to be washable. That is, as shown in FIG. 11, a square cleaning opening 403 is formed on the upper surface side of the upper liquid passage 313, and a substantially square plate-shaped opening lid 420 that detachably closes the opening 403 is attached. Has been done. The opening 403 opens upward from the upper end of the U-shaped side wall 404 of the upper liquid passage 313.

As shown in FIG. 12, the opening lid portion 420 has a downwardly convex cross section, and a lid plate 421 having a flange-shaped upper peripheral edge portion and a peripheral groove 422 formed on the lower peripheral edge portion of the lid plate 421. It is composed of a square frame-shaped packing 423 that is detachably fitted to the container. When the opening lid 420 is fitted into the opening 403, the flange 424 comes into contact with the upper end surface 405 of the side wall 404, and the packing 423 is in close contact with the inner circumference near the upper end of the opening 403, so that the upper liquid passage 313 The water-stopping seal and the opening lid 420 are prevented from coming off. The front end portion 425 of the flange portion 424 projects slightly forward, and when the opening lid portion 420 is fitted into the opening portion 403, it abuts on the upper wall 402 of the outlet 401 formed on the peripheral side surface 311 to cause the outlet 401. There is no gap between the opening lid and the opening lid 420.

When using the tabletop pot, the opening lid portion 420 is fitted into the opening portion 403 while the front end portion 425 of the flange portion 424 is brought into contact with the upper wall 402 of the outlet 401 in advance to fit the opening lid portion 420 into the internal opening. The inside of the upper liquid passage 313 other than the 400 and the outlet 401 can be isolated from the outside to prevent the liquid from leaking from the beverage.
When the plug 3 is removed from the shoulder member 2 and disassembled into the upper member 3b and the lower member 3a for cleaning, the opening lid portion 420 is further removed from the opening 403 to make the inside of the upper liquid passage 313 larger to the outside. It can be exposed and washed (see FIG. 11. Note that the valve mechanism 32 is omitted in FIG. 11).

According to this embodiment, the shaft portion 521 provided on the upper part of the main valve body 522 is vertically and vertically fitted to the guide portion 520 provided on the inner bottom surface 312 of the plug body, and is formed through the main valve body 522. A valve rod 525 having an auxiliary valve body 524 at the lower end was inserted into the hole 523 so as to be movable up and down, and the gap between the valve rod 525 and the through hole 523 was used as a pressure relief passage 537 and attached to the upper end of the valve rod 525. A first coil spring 528 for urging the valve rod 525 upward is interposed between the top portion 526 and the inner bottom surface 312, and the top portion 526 and the upper part of the main valve body 522 are on the inner diameter side of the first coil spring 528. Since the second coil spring 531 for urging the main valve body 522 downward is interposed between the shaft portions 521 of the valve mechanism, the valve mechanism is compared with the case where the first and second coil springs are arranged vertically. Can be miniaturized.
Further, since the first and second coil springs 528 and 513 can be arranged above the inner bottom surface 312 of the plug body 3, the first and second coil springs are used when the main valve body 522 is opened and the drinking liquid is poured. The area around 528 and 513 can be prevented from being soaked in the drinking liquid to prevent stains, and the labor of cleaning can be reduced.

The present invention is applicable to beverage containers such as pots and thermos bottles, which enable or prevent the liquid in the container body from being discharged to the outside by opening and closing the valve mechanism.
