A pump operation is performed. One end of a curved lever is rotatably attached to the lid of the bottle container, and the other end of the curved lever is disposed above the discharge nozzle. When pouring the liquid in the bottle container, place the thumb of one hand on the tip of the lever, place the palm of the same hand under the tip of the pouring nozzle, and press down the curved lever in this state. The upper end of the movable tube is pressed. With this pressing, the movable tube moves down, and the content discharged from the discharge nozzle falls to the palm.
In this case, since the bending lever is operated with the palm turned upward, there is an inconvenience that the burden on the thumb is large.

Next, the liquid container described in Japanese Utility Model Publication No. 10-2587089 has a bubble receiving tray provided below a nozzle provided on a piston protruding from a cap of the container. When pouring the liquid in the bottle container, by pressing the nozzle with one hand and moving the piston up and down,
The liquid discharged from the discharging nozzle is dropped into the recess of the bubble tray, and the liquid is scooped from the bubble tray. In this case, although all the operations can be performed with one hand, there is a disadvantage that the operation of discharging the liquid from the container and the operation of scooping the discharged liquid from the bubble tray must be performed separately.

Further, in the liquid container described in Japanese Patent Application Laid-Open No. 8-119309, a metering pump is mounted laterally to a container body, a push button is attached to a stem supporting a piston of the metering pump, and the container is A grip for operating a push button is attached to the main body.

In this case, while the palm is turned up with one hand, the finger of this hand is engaged with the grip portion and the push button is pressed laterally with the same palm, so that one-handed operation can be realized, but the amount of liquid received by the palm And the burden on the arm is large.

The liquid container described in Japanese Patent Application Laid-Open No. 9-56630 is rotatably connected to a base having a nozzle portion which can be held by four fingers of a hand, and a support provided on the base. And a pump mechanism which operates by a piston movement accompanying the pressing by the lever. When pouring the liquid in the bottle, place the four fingers of the hand below the nozzle, touch the belly of the thumb to the end of the lever, and operate this lever with your thumb. Thereby, the liquid is discharged from the nozzle portion and taken out to the four fingers of the same hand. In this case, since the nozzle portion is held with the four fingers of the hand and the lever is operated with the thumb of the same hand, one-hand operation can be realized, but the amount of liquid that can be received with the four fingers is limited, There is a disadvantage that the burden on the arm is large.

The liquid container described in Japanese Patent Application Laid-Open No. H10-264955 has a hand-operated pump attached to the lid of the container, and extends from a push portion for operating the pump and is openable at the push portion. And a supporting member attached to the pushing portion and bent so as to open to the upper surface of the pushing portion. When pouring out the liquid in the bottle container, by pushing down the support with the back of the hand and operating the pressing portion, the liquid in the container is discharged from the bent pipe provided in the nozzle portion and the palm of the same hand To fall. In this case as well, the supporter is pushed down with the back of the same hand to operate the pressing portion while the palm is turned up with one hand, so that one-handed operation can be realized, but there is a disadvantage that the burden on the arm is large.

As shown in FIGS. 1 to 3, the liquid container of the first embodiment includes a bottle 1 as a container main body for storing liquid, a liquid discharge nozzle 2 communicating with the inside of the bottle 1, and a top portion of the bottle 1. An opening that opens to the outside is formed, and the base 3 is attached to the opening. The base 3 is equipped with a manual pump (not shown) that sucks the liquid inside the bottle 1 and discharges the liquid toward the discharge nozzle 2. Such a manual pump is described, for example, in Japanese Utility Model Laid-Open No. 60-171574 by the present applicant. Therefore, a detailed description of the manual pump will be omitted.

Above the base 3, there is provided manual operation means which is formed integrally with the nozzle 2 and which will be described later and which operates a manual pump by one-handed operation of a user. 1 An inwardly displaceable depressing head 4 is formed integrally with the discharge nozzle 2, and a substantially U-shaped operating member 5 is mounted outside the head 4.

The operating member 5 has a base 5 having a semicircular cross section.
c and arms 5a and 5b connected to both ends of the base 5c by hinges 5h. Further, a pair of ends of the operation member 5 respectively have operation protrusions 5 protruding to the side of the head 4 when attached to the outside of the press-down head 4.
Construct p. In this case, it is preferable that a plurality of grooves for slip prevention are formed in the operation protrusion 5p.

The operation member 5 is arranged such that when the operation protrusion 5p is operated with one hand to discharge the liquid from the nozzle 2, the liquid can be received by the palm that has operated the operation protrusion 5p. At this time, the operation protrusion 5p is disposed so that the user can operate it with the palm of the hand turned upside down between the fingertips of the hand.

Here, as means for attaching the operating member 5 disposed above the manual pump described above, for example, there is one shown in FIG. As shown in this figure, a downwardly projecting projection 5g is integrally formed on a base 5c of the operation member 5, and a groove 3g into which the projection 5g of the base 5c is fitted is integrally formed on the base 3. That is, the operation member 5 is fixed to the bottle 1 via the press-down head 4 by fitting the protrusion 5g into the groove 3g of the base 3. However, when the projection 5g of the operating member 5 is fitted to the groove 3g of the base 3, the pressing head 4 is previously set at a normal height position, that is, a height position where no downward force acts on the pressing head 4. It is preferable to adjust to.

The means for attaching the operating member 5 is shown in FIG.
However, the present invention is not limited to this structure.
