【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partial vertical sectional view of a discharge container according to an embodiment of the present invention, and FIG. 2 is an external perspective view of the whole.

The discharge container includes a nozzle head 11 on the upper part of the container 10.

The container 10 is formed of a plastic material into a bottle shape, and a bellows 10b is formed on the body portion 10a. In the container 10, contents (not shown) such as shampoo and conditioner are stored.

The nozzle head 11 is attached to the mouth 10 c of the container 10. The nozzle head 11 has a tubular member 13, a discharge valve 14, and a shutoff member 16. In the tubular member 13, the inner tubular portion 18 is doubly provided inside the outer tubular portion 17. The outer cylinder part 17 is integrally formed with a beak-shaped nozzle 19 protruding from the outer circumference of the upper part, and the engaging projection 17a is partially provided on the inner circumference of the upper part, while the threaded part is provided on the inner circumference of the lower part. A vent hole 21 is provided vertically through the connecting portion 20 between the outer tubular portion 17 and the inner tubular portion 18. On the other hand, the inner cylindrical portion 18 is provided with a step portion 18a in the middle thereof and has a small diameter downward from the middle thereof to form a discharge passage 23 therein.

The discharge valve 14 is inserted into the discharge passage 23 in the inner cylinder portion 18 and the lower end thereof is placed on the step portion 18a.

The blocking member 16 is cap-shaped, and a small-diameter cylindrical portion 25 is provided inside the expanded-diameter cylindrical portion 24 concentrically therewith. The enlarged diameter cylindrical portion 24 has a short cylindrical shape and is provided with an engaging projection 24a partially on the outer periphery and a flange 24b on the upper edge. The small-diameter cylindrical portion 25 projects downwardly for a long time and has a vertical hole passage 25a therein. A connecting portion 26 is provided at a portion between the expanded diameter cylindrical portion 24 and the small diameter cylindrical portion 25 so as to be connected in the radial direction. A horizontal hole passage 27 is provided in the connecting portion 26 to communicate with the vertical hole passage 25a. A rubber tube 28 is fitted at the tip of the lateral hole 27.

Then, the enlarged diameter tubular portion 24 is rotatably fitted in the upper portion of the outer tubular portion 17 of the tubular member 13 except for the collar 24b, and the engaging projections 17a and 24a are engaged with each other to be removed. In addition, the small diameter cylindrical portion 25 is airtightly inserted into the discharge passage 23 to communicate the discharge passage 23 with the vertical hole passage 25a. At that time, an intake valve 22 for opening and closing the vent hole 21 is provided on the lower surface of the connecting portion 20, and the connecting portion 20 and the mouth portion 10c sandwich and support the intake valve 22.

Then, the upper end of the tube 15 is fitted to the lower end of the inner tubular portion 18 to communicate the inside of the tube 15 and the inside of the discharge passage 23. Then, the tube 15 and the inner cylinder portion 18 are passed through the mouth portion 10c of the container 10, the tube 15 is suspended in the container 10, and the outer cylinder portion 17 is screwed onto the outer periphery of the mouth portion 10c. Attach the nozzle head 11 to the container 10.

At that time, the discharge container is configured such that the discharge valve 14 blocks the discharge passage 23 by its own weight. Further, until the discharge container is used, the lateral hole passage 27 is displaced from the position of the nozzle 19 to block the passage from the discharge passage 23 to the nozzle 19.

Therefore, when using the discharge container, first, the blocking member 16 is rotated to align the arrow mark a in the direction of the nozzle 19 as shown in FIG. Then, as shown in FIG. 1, the horizontal hole passages 27 are aligned with the nozzles 19 and the insides of the nozzles 19 and the horizontal hole passages 27 communicate with each other. Therefore, the nozzle head 11 is pushed down, the bellows 10b portion is contracted, and the container 10 is contracted. Therefore, the pressure in the container 10 increases, and the discharge valve 14 is pushed up and opened by the pressure. Then, the content in the container 10 is guided into the nozzle 19 through the tube 15, the discharge passage 23, the vertical hole passage 25a and the horizontal hole passage 27, and discharged from the nozzle 19 to the outside.

After that, when the pushing down of the nozzle head 11 is released, the discharge valve 14 falls to the step portion 18a by its own weight and shuts off the discharge passage 23. At the same time, the intake valve 22 is opened by the restoring force of the bellows 10b portion, outside air is taken into the container 10 through the vent hole 21, and the container 10 is returned to its original state.

When the use of the discharge container is stopped, however, the blocking member 16 is rotated clockwise from the position shown in FIG. 3 by 90 degrees, for example, as shown in FIG. Then, the lateral hole passage 27 shifts from the position of the nozzle 19 and blocks the passage leading from the discharge passage 23 to the nozzle 19. At this time, the lateral hole passage 27 is sealed by the inner peripheral surface of the upper portion of the outer cylindrical portion 17.

In the above-described embodiment, the intake valve 22 that opens by the restoring force of the bellows 10b to take in the outside air is provided. However, although not shown, the intake valve 22 may not be provided, and the bellows 10b may be provided in a wide height range of the body 10a of the container 10. Then, after the contents are discharged, the container does not restore, and the container gradually shrinks and becomes smaller as the contents in the container decrease. Therefore, in this way, the volume of the container to be discarded can be reduced.

[0024]

[Effect of device]

 From the above, according to the present invention, when the container is contracted by contracting the bellows part, the discharge valve is opened by the increase of the pressure in the container and the content in the container is discharged from the nozzle. The height of the discharge container can be reduced by that amount, and the size of the discharge container can be reduced.

According to the second aspect, since the intake valve is opened by the restoring force of the bellows portion to take in the outside air into the container, the container is returned to its original state with a simple structure and the appearance of the container is improved. Can be maintained.

According to the third aspect of the present invention, when the shutoff member is externally operated to shut off the passage leading from the discharge passage to the nozzle, the content is not discharged from the nozzle even if the discharge valve is opened. It is possible to prevent leakage from the nozzle.
