The content liquid is pressed into the piston cylinder 11 through an opening provided on the outer periphery of the piston cylinder 11.

  A nozzle head C provided with a nozzle 15 is mounted on the upper portion of the piston cylinder 11, and a spring 16 is mounted between the nozzle head C and the mounting cap 12.

  The pump B and the nozzle head C only need to be capable of sucking up the content liquid from the nozzle 15 by moving the nozzle head C up and down, and the configuration thereof can adopt a conventionally known one. The pump device is not limited to the above.

The push-down member D includes a bottomed engagement tube 20 whose inner periphery is slidably fitted to the outer periphery of the cylinder 10 of the pump B, and a push bar 21 that is suspended from the center of the bottom wall of the engagement tube 20. Thus, the pump B is attached to the pump B so that a gap a is formed between the bottom surface of the bottom wall of the cylinder 10 of the pump B and the bottom wall of the engagement cylinder 20.
At a predetermined position of the engagement cylinder 20, an opening 22 serving as a flow path for the content liquid is formed so as to extend from the top to the bottom wall.

  The sliding bottom plate E is provided with an annular inclined plate 26 provided with a skirt-like elastic peripheral wall 25 that is slidably fitted into the inner surface of the body peripheral wall 3, and is suspended from the inner peripheral edge of the inclined plate 26. And a bottomed cylinder 28 provided with 27.

The bottom portion 27 includes an outer cylindrical portion 30 that is continuous with the inner peripheral edge of the bottom wall 28 a of the cylindrical body 28 and an inner cylindrical portion 31 that is continuous with the inner periphery of the lower end of the outer cylindrical portion 30.
The upper part of the inner cylinder part 31 is reduced in diameter toward the upper side, and the inner periphery of the upper end is an engaging part 32 into which the outer periphery of the push bar 21 of the push-down member D is slidably fitted.
On the inner periphery of the lower part of the inner cylinder part 31, a locking protrusion 34 for mounting the ball 33 in the inner cylinder part 31 in a liquid-tight manner is provided.

The bottom cover F is erected on the bottom plate 36 in which the inner cylinder 35 abuts the lower surface of the bottom wall 28a of the cylindrical body 28 of the sliding bottom plate E at the upper end, and the peripheral edge of the bottom plate 36. The side periphery cylinder 37 which an outer periphery engages with the inner periphery of the attachment part 5 of this is comprised.
An air hole 38 is formed at a predetermined position of the bottom plate 36.

Next, the effect of this liquid pouring container is demonstrated.
In the liquid dispensing container of the present invention, a cream-like liquid is stored as the contents, and the content liquid in the container main body A is sucked up by the pump B and discharged from the nozzle 15 by the pressing operation of the nozzle head C. The
Further, as the content liquid is sucked, the inside of the container main body A becomes negative pressure, the sliding bottom plate E rises, and the atmosphere is introduced from the air hole 38 of the bottom lid F.

  As shown in FIG. 2, when the sliding bottom plate E rises to a certain position, the push bar 21 of the pressing member D is inserted into the inner periphery of the engaging portion 32 of the inner cylindrical portion 31 of the bottom portion 27 of the sliding bottom plate E, It slides liquid-tightly, and the lower end of the push rod 21 comes into contact with the upper end of the ball 33 in the inner cylinder part 31.

When the sliding bottom plate E is further raised, as shown in FIG. 3, the lower end of the push rod 21 pushes down the ball 33, the ball 33 comes off from the inner cylinder portion 31, falls, and collides with the bottom lid F to generate sound. To do.
Since the ball 33 falls and generates a sound, it can be recognized that the content liquid has reached a certain remaining amount.

  Further, even if the ball 33 is missed when the ball 33 is dropped, if the pouring container is shaken, the ball 33 is moved into the inner surface of the inner cylinder 35 of the bottom lid or the inner surface or inner cylinder of the trunk peripheral wall 3 of the container body. Because it collides with the outer surface of 35 and generates sound, it can be recognized that the liquid content is less than a certain remaining amount, and knows that the next new liquid dispensing container must be prepared be able to.

  When the liquid is sucked up after the ball 33 is dropped, the sliding bottom plate E rises, and the upper surface of the bottom wall 28a of the cylindrical body 28 of the sliding bottom plate E contacts the lower surface of the bottom wall of the engaging tube 20 of the push-down member D. The push-down member D is slid and raised with respect to the cylinder 10 of the pump B by being pushed up in contact.

  When changing the remaining amount to be confirmed, the length of the push bar 21 of the push-down member D, the height of the interval a formed by the push-down member D and the cylinder 10 of the pump B, or the sliding bottom plate By adjusting the height of the bottom 27 in E, it can be changed as appropriate.

  In the above embodiment, the ball 33 is placed in the inner cylindrical portion 31 of the bottom portion 27 of the sliding bottom plate E. However, instead of the ball 33, as shown in FIG. You may make it attach the liquid-tight cylindrical member 40 made into the upper and lower two steps | steps latched via the latching protrusion 34. FIG.

  Even when the cylindrical member 40 is attached, as shown in FIG. 5, the sliding bottom plate E rises as the liquid contents are sucked up, and the inner cylindrical portion 31 of the bottom portion 27 of the sliding bottom plate E is engaged. The push rod 21 of the push-down member D is inserted into the inner periphery of the portion 32 and slides in a liquid-tight manner. The lower end of the push rod 21 pushes down the upper surface of the cylindrical member 40. As shown in FIG. It is possible to obtain the same effect as that of the above-described embodiment in which sound is generated by falling from the inside of the portion 31 and falling and colliding with the bottom lid F.

  Therefore, the present invention recognizes that, as the sliding bottom plate rises, it comes into contact with the push rod of the push-down member, is dropped, collides with the inside of the container, generates sound, and reaches a certain remaining amount. Any falling object can be used, and the configuration of the falling object is not limited to the configuration of the above embodiment.

According to the present invention, in a bottom-up type liquid dispensing container with a pump, as the sliding bottom plate rises, falling objects placed in the sliding bottom plate come off and collide with the container to generate sound, and certain residual You can know that the amount is less than the amount.
In addition, the present invention can be effectively used for a liquid dispensing container having an opaque container body regardless of the type of content liquid, and can also be used for a translucent container body.
