In a cream-type liquid pouring container with a pump bottom that contains the contents in an opaque container body, when the sliding bottom plate reaches a certain ascending position, the sphere mounted on the lower surface of the sliding bottom plate is dropped, A container in which a sphere collides with the inner surface of the container to generate sound when the container is shaken in that state has been known (for example, see Patent Document 1).
JP 2002-320886 A

However, in the container described in Patent Document 1, when the spherical body holding part of the sliding bottom plate comes into pressure contact with the lower end of the cylinder of the pump, the spherical body is dropped. It was impossible to know when the liquid content was low and the remaining amount was constant.
Therefore, there is a possibility that a problem arises in that it is not known when to seek a new container and prepare to replace it.

  An object of the present invention is to solve the above problems, and in a liquid dispensing container having an opaque container main body for light shielding, the content liquid is reduced when the content liquid is poured out, and a certain amount remains. It is an object of the present invention to provide a cream-type liquid pouring container of a bottom-up type with a pump that can detect when the sound is generated by the generation of sound by a whistle.

In order to solve the above problems, the present invention provides an opaque container body as a liquid dispensing container, a pump attached to the mouth tube portion of the container body, and a nozzle head attached to the upper end, and a barrel of the container body.

A whistle support tube for supporting a whistle on the bottom plate. The plug body has a plug portion for closing the upper end of the whistle body, and the lower end of the whistle body communicates with the atmosphere. The configuration is characterized in that sound is generated by the passage of air.
Further, as an embodiment of the plug body, a configuration is adopted in which the plug body is provided with a small hole through which air flows on the bottom surface of the plug portion.

A plug that closes the whistle support is suspended from a locking piece on the bottom surface of the bottom plate of the sliding bottom plate by a wire having a certain length, and a whistle that supports the whistle body whose lower end communicates outside air to the bottom plate of the bottom lid. When the support was erected and the sliding bottom plate was in a certain raised position, the plug was removed from the whistle support and produced a sound, so the remaining amount of the liquid content was constant. I can know that.
Further, the remaining amount to be confirmed can be adjusted by changing the length of the wire.

  A nozzle head C provided with a nozzle 16 is mounted on the stem 15 of the piston 11 via a mounting cylinder 17, and a spring 18 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 discharging the content liquid from the nozzle 16 by moving the nozzle head C up and down. It is not limited to a device.

As shown in FIG. 1.2, the sliding bottom plate D includes an annular inclined plate 21 provided with a skirt-like elastic peripheral wall 20 slidably fitted on the inner surface of the body peripheral wall 3, and an inner portion of the inclined plate 21. A cylindrical body 23 is provided vertically from the periphery and has a bottom plate 22 connected to the lower end.
The inclination angle of the inclined plate 21 substantially coincides with the inclination of the shoulder 2, and the cylindrical body 23 has a size that covers the outer periphery of the lower part of the cylinder 10 of the pump B. The content liquid above is almost completely dispensed.

  A locking piece 24 having a bulging ring at the lower end is suspended from the lower surface of the bottom plate 22, and a wire rod 26 having a cylindrical plug 25 suspended at the lower end is connected to the locking piece 24. The provided locking ring 27 is fitted and locked.

The plug body 25 is composed of a cylindrical body 28 and a cylindrical plug section 29 having a reduced diameter below. A bottom hole 30 of the plug section 29 has a small hole 31 communicating with air at the center.
In addition, instead of the small holes 31 on the bottom surface 30, a ventilation groove through which air communicates may be provided on the peripheral surface of the plug body 25.
The locking ring 27, the wire rod 26, and the spherical pendulum 25 are integrally formed, but may be formed and joined as separate bodies.

The bottom cover E is composed of a bottom plate 35 and a side peripheral wall 36 erected on the periphery of the bottom plate 35. The bottom plate 35 has a support cylinder 37 on which the bottom plate 22 of the sliding bottom plate D is placed and a whistle holding cylinder. 38 is erected.
A reinforcing rib 39 is provided between the outer periphery of the support cylinder 37 and between the outer periphery and the bottom plate 35.

The whistle holding cylinder 38 is erected on the inner side of the support body 37, and a stepped portion 40 is provided on the upper portion thereof, and the upper end thereof is a sealed portion 41 into which the plug portion 29 of the plug body 25 is inserted.
The diameter of the lower portion of the whistle holding cylinder 38 is reduced to form an insertion portion 43 for the whistle 42.

The whistle 42 includes a flange portion 44 placed on the stepped portion 40 and a whistle body 45. The whistle body 45 has an air hole communicating with the small hole 31, a reed valve and other known sound generating mechanisms. In addition, a sound generating hole for generating sound by the passage of air is provided, and the sound generating hole is closed by a plug portion 29.
The lower end of the whistle body 45 protrudes from the whistle holding cylinder 38 and communicates with the atmosphere.
The sound intensity, tone color, and the like of the whistle 42 can be appropriately determined by selecting a sound generation mechanism.

Next, the effect of this liquid pouring container is demonstrated.
In the liquid dispensing container of the present invention, a creamy liquid is stored as the contents, and the content liquid in the container main body A is sucked up by the pump B by the operation of pushing down the nozzle head C and is discharged from the nozzle 16. The

In response to the suction of the liquid content, the inside of the container body A becomes negative pressure, the sliding bottom plate D rises, and air is introduced from the lower end of the whistle body 45 of the bottom lid E through the air hole and the small hole 31 of the plug body. The
As the sliding bottom plate D rises, the wire 26 is pulled up through the locking ring 27 that engages with the locking piece 24 on the bottom surface of the bottom plate 22, and when the sliding bottom plate D rises to a certain position, as shown in FIG. In addition, the wire rod 26 is pulled and given a constant tension.

When further raised, the plug body 25 is removed from the whistle support tube 38 as shown in FIG.
By removing the plug body 25, air flows through the large-diameter sound generating hole, sound is generated, and the whistle 42 sounds.
At that time, since the air suddenly flows during the removal, the generation of sound stands out and can be clearly recognized.
After the plug body 25 is removed, the air flow is introduced through a large-diameter sound generating hole, a sound is generated every time the content liquid is sucked, and the whistle 42 sounds.

Therefore, when the content liquid is poured out and reaches a certain remaining amount, the whistle sounds, so that it can be confirmed that the certain remaining amount has been reached.
After that, since a sound is generated and a whistle sounds every time, it is possible to confirm that the liquid content is low and to prepare the next new liquid dispensing container. I can know.

  When changing the remaining amount of a certain amount to be confirmed, it can be changed as appropriate by adjusting the length of the wire 26.

  In the above-described embodiment, the sound generating hole and the whistle main body 54 having the air hole are used. However, depending on the sound generating mechanism, when flowing through the small hole 31, no sound is generated and the plug 25 is removed. Since the sound can be generated in the case of flowing by the air, the air hole in the whistle body 45 may not be provided.

  Moreover, in the said embodiment, although the small hole 31 was provided in the plug body and the air | atmosphere introduction with the raise of a sliding bottom plate was always performed through the whistle body, as another example, the small hole 31 of the plug body was eliminated. The air is introduced separately, and an air introduction hole is drilled in the bottom plate around the whistle support tube of the bottom lid. When the whistle support tube is closed by the plug, air is introduced through the air introduction hole, After the body is removed, air may be introduced through the whistle body.

In the case of the present embodiment, sound is generated when the plug body is removed, and thereafter, the atmosphere flows in through the larger diameter whistle body, so that the same effect as the embodiment can be obtained.
Further, when the plug is removed, the flow path through the air introduction hole may be blocked.

In the liquid raising container of the bottom raising type with a pump according to the present invention, the plug that closes the whistle support of the bottom cover is removed with a certain rise of the sliding bottom plate, and a sound is generated to smooth the whistle. Therefore, it can be known that the content has become below a certain remaining amount.
And this invention can be utilized for the liquid extraction container which has an opaque container main body irrespective of the kind of content liquid, Furthermore, it can utilize also in the case of a translucent container.

It is a partial cross section elevation of this invention liquid pouring container. It is the partial cross section elevation which expanded the sliding baseplate and bottom cover which are going up. It is a partial cross section elevation when a sliding bottom plate raises to a fixed position. It is a partial cross section elevation when a plug body leaves | separates from a whistle holding cylinder.
