The rubber-based packing 5 is attached to the bottom of the lid 4 to maintain airtightness in the container 1.

[0003] In the above configuration, a liquid detergent is put into the container 1, the opening 4 of the container 1 is closed by screwing the lid 4 with a female screw 3 and a female screw 3, and a pressure device (not shown) is used. By applying a predetermined pressure to the inside of the container 1, the container 1
A liquid detergent is supplied by pumping a predetermined amount of liquid agent from the inside.

[0004]

In such a conventional configuration, in order to supply the liquid detergent from inside the container 1, it is necessary to keep the inside of the container 1 airtight.

On the other hand, when the user frequently opens and closes the lid 4 such as when a liquid detergent is automatically supplied by a washing machine,
Loss of the lid 4 is a conceivable situation. For example,
It is also conceivable that the user drops the lid 4 and enters the gap of the washing machine so that the lid 4 cannot be removed.

Therefore, in the case where the function becomes inoperable due to the loss of the lid 4, it is desired to supply the lid 4 which is not lost.

The present invention solves the above-mentioned problems, and prevents the lid from being lost or dropped, keeps the inside of the container airtight, and can stably supply the liquid medicine without impairing the automatic liquid medicine supply function. It is intended to be.

[0008]

According to the present invention, in order to achieve the above object, an opening for introducing a liquid agent into a container is closed by a lid, the inside of the container is kept airtight, and the container is pressurized by pressurizing means. A predetermined pressure is applied to the inside of the container, and a predetermined amount of the liquid agent is pumped from the inside of the container, and the lid is integrally formed with an outer lid that covers the clothing inlet.

Thus, the lid can be prevented from being lost or dropped, the inside of the container can be kept airtight, and the liquid material can be supplied stably without impairing the liquid material automatic supply function. it can.

BEST MODE FOR CARRYING OUT THE INVENTION
A container having an opening for charging a liquid agent, a lid attached to the opening to keep the inside of the container airtight, and a pressurization for applying a predetermined pressure to the container and forcing a predetermined amount of liquid agent from inside the container Means, the lid is configured integrally with the outer lid covering the clothing slot, the loss of the lid, can be eliminated, it is possible to hold the inside of the container airtight,
The liquid agent can be supplied stably without impairing the liquid agent automatic supply function.

According to a second aspect of the present invention, in the first aspect of the present invention, the lid is formed below the outer lid, and the lid is positioned above the opening of the container. When the lid is closed, the lid covers the opening to keep the inside of the container airtight, so that the user can be prevented from forgetting to close the lid, and the liquid agent can be supplied stably.

[0012]

An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the water receiving tub 6 has a washing and dewatering tub 7 rotatably disposed inside, and a hanging rod 9
It is elastically supported through such as. An upper cover 10 is provided above the outer shell 8, and a water supply valve 11 for supplying water to the washing and dewatering tub 7 and a control device 12 for controlling the operation of the washing machine are provided in the upper cover 10.

The container 13 is provided inside the upper cover 10, and is charged with a liquid detergent (liquid agent) 14, and the opening 15 protrudes from the upper cover 10. The outer lid 16 is formed above the upper cover 10 so as to cover a clothing slot (not shown) provided in the upper cover 10, and a lid 17 for closing the opening 15 of the container 13 with the outer lid 16. The container 13 is integrally formed, and the inside of the container 13 can be kept airtight by the lid 17.
