The discharge port portion 16 has a cylindrical shape that opens downward, communicates with the internal space S of the container body 10, and faces the upper wall 12c of the container lower portion 12 with the space portion 14 interposed therebetween.

In the present embodiment, the discharge port 16 is provided coaxially with the filling port 15.

A discharge cap 30 made of synthetic resin is attached to the discharge port 16. In the present embodiment, the discharge cap 30 is configured to be attached to the discharge port 16 by screw coupling, but may have another configuration.

The discharge cap 30 includes a discharge port 31 for discharging the contents L stored in the internal space S to the outside. In the present embodiment, the discharge port 31 is configured as a spray nozzle that ejects the contents L in the form of mist.

The discharge cap 30 is provided with an on-off valve 40 made of synthetic resin. A connection cylinder 32 communicating with the discharge port 31 is fitted and fixed to the inner surface of the discharge cap 30 facing the internal space S, and the on-off valve 40 is arranged inside the connection cylinder 32. The on-off valve 40 has a valve body 41 that can move between a closed position that closes the intake hole 32a provided in the connection cylinder 32 and an open position that descends from the closed position and opens the intake hole 32a. The spring portion 42 that urges the 41 toward the closed position is integrally formed of a synthetic resin material.

In the on-off valve 40 having the above configuration, in a normal state where the pressure inside the internal space S is atmospheric pressure, the flange portion of the valve body 41 is in the closed position, and the intake hole 32a of the connecting cylinder 32 is closed to close the discharge port. The communication between 31 and the internal space S is cut off. Therefore, when the valve body 41 is in the closed position, the content L housed in the internal space S is held inside the internal space S without being discharged or leaked from the discharge port 31. On the other hand, when the pressure inside the internal space S of the on-off valve 40 becomes a predetermined value higher than the atmospheric pressure, the valve body 41 moves downward against the elastic force of the spring portion 42 due to the pressure and is in the open position. Therefore, the discharge port 31 is communicated with the internal space S. As a result, the content L pressurized to the atmospheric pressure or higher in the internal space S is taken into the inside of the connecting cylinder 32 through the intake hole 32a and then discharged to the outside from the discharge port 31.

The discharge cap 30 may be configured to have a pipe member 33 made of synthetic resin attached. In this case, the pipe member 33 is attached to the connection cylinder 32 of the discharge cap 30 so that one end 33a communicates with the intake hole 32a, and the other end 33b is bent in the middle and the lower part of the container as shown in FIG. It extends to 12 and is placed in the vicinity of the bottom wall 12a. By providing such a pipe member 33, the remaining amount of the content L can be reduced by sucking and discharging the content L from the bottom portion of the container body 10.

The discharge cap 30 is provided with a synthetic resin knob 50 arranged below the discharge port 31. As shown in FIG. 3, in the present embodiment, four pillar portions 51 extending in the vertical direction and arranged at equal intervals in the circumferential direction are integrally provided on the lower surface of the discharge cap 30, and the knob portion 50 is provided. Is formed in an annular shape centered on the axis of the discharge port 31, and is integrally connected to the lower ends of the four pillar portions 51. The distance between the discharge cap 30 and the grip portion 50 is set so that the user can pinch the grip portion 50 with his / her fingers. The user can apply a downward pulling force to the upper portion 11 of the container by inserting the hand into the space portion 14 with the palm facing upward, pinching the grip portion 50 with fingers and pulling downward.

The discharge cap 30 is provided with an outside air introduction hole 34 that allows the internal space S to communicate with the outside of the container body 10. Further, the discharge cap 30 is a synthetic resin outside air introduction valve that operates to close the outside air introduction hole 34 and open the outside air introduction hole 34 when the internal space S becomes a negative pressure (pressure less than atmospheric pressure). 35 is provided. By providing the outside air introduction hole 34 and the outside air introduction valve 35 having such a configuration, the contents L can be prevented from leaking to the outside from the outside air introduction hole 34 and the pressure inside the internal space S. After being discharged from the discharge port 31, outside air can be taken into the internal space S to maintain the pressure inside the internal space S at atmospheric pressure.

The outside air introduction hole 34 and the outside air introduction valve 35 may be provided in the block cap 20, or may be provided in both the block cap 20 and the discharge cap 30, but the discharge container 1 with a pump can be easily cleaned. Considering the fact that it can be obtained, it is preferable that the outside air introduction hole 34 and the outside air introduction valve 35 are provided in the discharge cap 30 as in the present embodiment.

As shown in FIGS. 1 and 2, the lower portion 12 of the container is integrally provided with a bellows pump portion 60 that can be expanded and contracted in the vertical direction. The bellows pump portion 60 is provided integrally with the container lower portion 12 by forming a part of the peripheral wall 12b of the container lower portion 12 into a bellows-shaped bent shape over the entire circumference. The bellows pump unit 60 expands and contracts in the vertical direction when a load in the vertical direction is applied, and operates so as to increase or decrease the pressure inside the internal space S of the container body 10. Further, when the load in the vertical direction is released, the bellows pump portion 60 can be restored to its original shape by its own elastic force from the state of being expanded and contracted in the vertical direction. The bellows pump portion 60 may be provided in the middle portion 13 of the container, or may be provided in both the middle portion 13 of the container and the lower portion 12 of the container.

Next, a method of using the discharge container 1 with a pump having the above configuration will be described.

First, prior to use, the closing cap 20 is opened to fill the internal space S from the filling opening 15 with a predetermined amount of the content L such as a disinfectant, and the closing cap 20 closes the filling opening 15. ..

In this state, the palm is turned upward, the hand is inserted into the space portion 14, the pinched portion 50 is picked up by the fingers, and the pulling portion is pulled downward to perform the pulling operation. At this time, the discharge port 31 is arranged above the palm.

When a downward pulling force is applied to the upper portion 11 of the container by the pulling operation, the pulling force is transmitted to the bellows pump portion 60 via the portion above the bellows pump portion 60 of the middle portion 13 of the container and the lower portion 12 of the container. Then, the bellows pump portion 60 is elastically deformed so as to reduce the vertical dimension. When the bellows pump portion 60 is elastically deformed so as to reduce the vertical dimension, the volume of the internal space S is reduced and the pressure inside the internal space S is increased. Then, when the knob portion 50 is pulled down to a certain extent and the pressure inside the internal space S becomes equal to or higher than a predetermined value, the on-off valve 40 opens and the content L stored inside the internal space S passes through the pipe member 33. It is discharged to the outside from the discharge port 31.

At this time, since the palm holding the gripping portion 50 is located below the discharge port 31, the content L is discharged toward the palm. Therefore, the content L can be discharged to the palm by a simple operation of picking the grip portion 50 and pulling it downward.

Here, in the conventional discharge container with a pump in which the pump is operated when the nozzle head is pushed down and the contents are discharged from the nozzle provided in the nozzle head, the contents are used as a disinfectant. Even if there is, since the nozzle head is pushed down by the hand before the contents are applied, the nozzle head becomes unsanitary, and then the hand of the user who uses the discharge container with a pump becomes dirty. There was a problem that there was a risk.

On the other hand, in the discharge container with a pump of the present embodiment, the discharge cap 30 is provided with a grip portion 50 arranged below the discharge port 31, and the grip portion 50 is picked up by a finger to perform a pulling operation. Since the object L is configured to be discharged from the discharge port 31, the content L discharged from the discharge port 31 is discharged to the palm of the hand that picks the grip portion 50, and also adheres to the grip portion 50. .. Therefore, when the content L to be filled in the internal space S is used as a disinfectant, the disinfectant is adhered to the knob 50 touched by the fingers of the hand each time the content L is discharged from the discharge port 31 to disinfect. be able to. As a result, the knob 50 that the fingers of the hand touch can be kept hygienic.

In particular, when the discharge port 31 is a spray nozzle that ejects the content L in the form of mist, the content L is ensured to adhere evenly and reliably to the grip portion 50 to keep the grip portion 50 more hygienic. It becomes possible.

The discharge container 1 with a pump is operated by manually pushing down the portion above the bellows pump portion 60 of the discharge container 1 with a pump, instead of pinching and pulling down the grip portion 50 as described above. , The bellows pump portion 60 can be elastically deformed so as to be reduced, and the content L can be discharged from the discharge port 31.

In the discharge container 1 with a pump having the above configuration, a part of the lower portion 12 of the container is configured as a bellows pump section 60, and the bellows pump section 60 is elastically deformed so as to reduce the vertical dimension to discharge the contents L. Since it is configured to discharge from 31, all the parts can be made of synthetic resin without the need to use a metal member such as a coil spring as a pump member. As a result, it is not necessary to separate the metal parts at the time of disposal, and the recyclability of the discharge container 1 with a pump can be improved.

It goes without saying that the present invention is not limited to the above-described embodiment and can be variously modified without departing from the gist thereof.

For example, in the above-described embodiment, the discharge container 1 with a pump is used for storing a disinfectant solution or a hand soap as a content, but the present invention is not limited to this, and for example, cosmetics, body soap, shampoo, and the like. It can also be used for storing various contents such as wash pigments.
