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 of remaining amount is obtained. An object of the present invention is to provide a cream-type liquid pouring container of a bottom-up type with a pump so that it can be known.

  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 liquid dispensing container comprising a sliding bottom plate inserted into the peripheral wall so as to be able to rise and a bottom lid attached to the lower end of the container main body, and the sliding bottom plate has a bottom plate continuously provided at the lower end. It has a cylindrical body, a locking piece is provided on the bottom plate bottom surface, and a locking ring is attached to the locking piece and a wire rod with an upper plug member suspended is attached to the bottom plate. A holding cylinder is erected on the bottom plate, and a locking plate for supporting the upper plug member is connected to a predetermined position of the holding cylinder, and the bottom plug is connected to the upper plug member from the lower side of the locking plate. The structure characterized by having attached the member is employ | adopted.

  A stopper member on the bottom surface of the bottom plate of the sliding bottom plate is suspended by a wire member having a certain length, and a holding cylinder holding the bottom stopper to be locked to the stopper member is provided on the bottom plate of the bottom cover, and slides. When the bottom plate is in a certain raised position, the bottom plug is separated from the holding cylinder and falls, and the upper plug member can swing around the locking piece.

By confirming that the bottom stopper has fallen, it can be known that the remaining amount of the liquid content has reached a certain level.Further, by shaking the container, the stopper member becomes a pendulum on the inner peripheral wall of the container body. Since the sound is generated by the collision, it can be known that the remaining amount of the content liquid is below a certain amount.
Further, the remaining amount to be confirmed can be adjusted by changing the length of the wire.

The content liquid is press-fitted through the opening.

  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 sucking up the content liquid by moving the nozzle head C up and down and discharging the content liquid from the nozzle 16. The pump device is not limited to the above.

As shown in FIGS. 1 and 2, the sliding bottom plate D includes an annular inclined plate 21 provided with a skirt-like elastic peripheral wall 20 that is 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 portion 2, and the cylinder body 23 is sized to cover the outer periphery of the lower part of the cylinder 10 of the pump B. The liquid content 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 with an upper plug member 25 suspended from the lower end is connected to the locking piece 24. The locking ring 27 is fitted and locked.
The locking ring 27, the wire material 26, and the upper plug member 25 are integrally formed, but may be formed and joined as separate bodies.

The upper plug member 25 includes an upper cylindrical portion 30, a bottomed lower cylindrical portion 31, and a locking projection 32 that is suspended from the lower surface of the lower cylindrical portion 31.
When the sliding bottom plate D is placed on the bottom cover E, the locking ring 27 is accommodated in the inner periphery of the upper cylindrical portion 30, and the tip of the locking piece 24 is accommodated in the inner periphery of the lower cylindrical portion 31. It has become.

The bottom cover E is erected on an annular bottom plate 35, an inner peripheral edge of the bottom plate 35, a holding cylinder 36 on which the bottom plate 22 of the sliding bottom plate D is placed, and an outer peripheral edge portion of the bottom plate 35. It comprises a side peripheral wall 37 that fits into the attachment portion 5 at the lower end of the A peripheral wall 3.

The engagement cylinder 41 has a diameter slightly smaller than the diameter and the inner periphery engages with the locking protrusion 32 of the upper plug member 25 of the sliding bottom plate D.

When the bottom plug member 39 and the locking projection 32 of the upper plug member 25 of the sliding bottom plate D are engaged with the inner peripheral edge of the locking plate 38, the upper plug member 25 and the bottom plug member 39 are allowed to flow through the air. It is installed with a gap to become a road.
In addition, by forming an air hole serving as an air flow path at a predetermined position of the bottom plate 35, the upper plug member 25 and the bottom plug member 39 are not provided with a gap on the inner peripheral edge of the locking plate 38. The engagement tube 41 of the bottom plug member 39 may be formed so as to be mounted.

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

As the content liquid is sucked, the inside of the container main body A becomes negative pressure, the sliding bottom plate D rises, and the atmosphere is introduced from the air flow path of the bottom lid E.
As the sliding bottom plate D rises, the wire 26 is pulled up through a locking ring 27 that engages with a locking piece 24 on the bottom surface of the bottom plate 22.

As shown in FIG. 3, when the sliding bottom plate D rises to a certain position, the upper plug member 25 is pulled up by the wire 26, and when the sliding bottom plate D rises further, as shown in FIG. 25 and the bottom plug member 39 are disengaged, the upper plug member 25 is pulled upward, the bottom plug member 39 is blocked by the locking plate 38, and falls out of the container.
It is possible to know that the content liquid has reached a certain remaining amount by dropping the bottom plug member 39.

  At that time, if the liquid pouring container is held in hand, the bottom plug member 39 can be clearly dropped, and if it is placed on the base plate or floor surface, Since the sound is generated when the bottom plug member 39 collides with the placement surface, it can be recognized that the remaining amount is constant.

  Even when the bottom plug member cannot be confirmed, if the user shakes the liquid dispensing container when the user thinks that the remaining liquid is low, the top plug member 25 collides with the inner surface of the body peripheral wall 3 of the container and makes a sound. Therefore, it can be confirmed that the content liquid exceeds a certain remaining amount and is low, and it is possible to know that the next new liquid dispensing container must be prepared.

  When changing the remaining amount to be confirmed, it can be changed as appropriate by adjusting the length of the wire 26 or the position of the locking plate 38 of the holding cylinder 36 of the bottom cover E.

In the liquid raising container of the bottom raising type with a pump, as the sliding bottom plate rises, the top stopper member of the bottom lid can be detached from the bottom lid and swing, and the bottom stopper member falls. You can know that the amount is below a certain level.
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 main body.

It is a partial cross section elevation of this invention liquid pouring container. It is the partial cross section elevation which expanded the sliding bottom plate 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 bottom plug member leaves | separates from an upper plug member and falls.
