[Industrial applications]

 The present invention relates to a discharge container in which compressed air and a substance to be discharged are housed in a container body and the substance to be discharged is discharged to the outside by the operation of this compressed air, and in particular, the compressed air in the container body is replenished. It relates to a discharge container equipped with a compressed air replenishment function.

[0002]

[Prior art]

 Generally, in a discharge container in which the substance to be emitted is released to the outside by the action of the compressed air stored in the container body, in order to release the substance to be emitted to the outside, Therefore, at the manufacturing and shipping stage, compressed air is stored in the container body at a high pressure.

The pressure of the compressed air stored in the container body is set in the initial state where a large amount of substances to be discharged are contained in the container body, and the compressed air is discharged by subsequent use. When the amount of the substances is reduced, the volume of the compressed air in the container body is increased with the reduction of the substances to be released, and the pressure of the compressed air is gradually reduced.

This pressure drop occurs remarkably in compressed air as compared with other pressurizing gases, and as a result, a sufficient pressure cannot be obtained in the container body in the state of the latter stage of use in which the substances to be released are reduced. In some cases, the container may be in an unusable state (cannot be discharged) even though the discharged substance remains in the container body, and the discharged substance must be disposed of in a state where it is not completely used up. .

Therefore, in order to solve such a drawback, there is a conventional one disclosed in Japanese Utility Model Laid-Open No. 2-70749, which is different from the fixed side member provided on the fixed side member provided in the container body. The movable side member provided with the body is fitted, and the space formed between the two is reduced at the time of fitting to compress the air in the space, and the compressed air is replenished into the container body. The pressure of the compressed air in the container body was increased by.

[Problems to be solved by the device]

 However, since the one disclosed in Japanese Utility Model Laid-Open No. 2-70749 uses a movable side member that is separate from the container body, when the replenishment work is not performed, the movable side member is stored somewhere. In addition, it is necessary to take out the movable side member from a predetermined place and fit it into the fixed side member also in the refilling work, which is a troublesome handling.

In view of this, the present invention provides a discharge container having a compressed air replenishment function that enables the compressed air replenishment work to be performed in a simple procedure and facilitates its handling. The purpose is to

[0008]

[Means for Solving the Problems]

 The discharge container equipped with the compressed air replenishing function of the present invention is provided on the container body that discharges the substance to be discharged by the action of the stored compressed air and a part of the container body. Cylinder equipped with a primary valve that opens from the inside toward the inside of the container body, a secondary valve that opens from the outside of the container body toward the inside of the cylinder, and a space that follows the primary valve inside the cylinder It has a guided part (for example, a protrusion) for sliding in the longitudinal direction of the cylinder to open and close the primary valve and the secondary valve by changing the volume of the part, and it does not rotate with respect to the cylinder as a whole. And a piston provided on the container body, which is provided on the container body in a state where the rotation position is held by the elastic member, and is rotatable with respect to the cylinder against the bias of the elastic member. A spiral guide that corresponds to the guide For example, a rotating member provided with a spiral groove portion) is provided, and further, the rotating member is provided with a string-shaped member with one end attached to the outer peripheral surface of the rotating member and wound around the outer peripheral surface. It is a thing.

[0009]

[Action]

 In this way, when the rotating member is rotated against the biasing force of the elastic member, the guided portion of the piston is guided by the spiral guide portion, so that the piston moves in the space of the cylinder. It moves in the direction of reducing the volume. As a result, the air contained in the space is compressed, and when the pressure becomes higher than the pressure in the container body, this compressed air enters the container body via the primary valve. At this time, the secondary valve is closed.

Further, when the rotating member is released from this state, the rotating member is rotated toward the original state by the urging force of the elastic member, whereby the guided portion is re-formed into the spiral guide portion. As a result, the piston is slid in the direction to return it to its original state. At this time, external air enters the space inside the cylinder via the secondary valve, and this air becomes compressed air to be replenished next time. When the rotary member is provided with a string-shaped member, the compressed member is replenished by pulling the string-shaped member to rotate the rotary member.
