Therefore, the locked state between the claw 5c of the elastic piece 5d provided on the cover 5 and the protrusion 2c provided on the mouth portion 2a of the container 2 can be easily released as in the ejection container 1A. .. Similar to the ejection container 1A, the cover 5 can be removed from the container 2 simply by pulling it up from the container 2, as shown by the arrow in FIG.

For example, when attempting to refill the ejection container 1B using the replacement container 20 of FIG. 9, in the present embodiment, the cap 21 is removed from the replacement container 20, the cover 5 is attached to the container 2, and then the cover 5 is attached. The ejection head 4 is attached to the pump 3. In this case, the ejection head 4 can be attached so that the front wall 4w1 (spout outlet 4a) faces the front in a plan view as shown in FIG. 16A. This completes the replacement of the ejection container 1B. Further, in this case, as shown in FIG. 16B, the ejection head 4 can be attached so that the front wall 4w1 (spouting outlet 4a) faces diagonally with respect to the front surface in a plan view. However, in the case of mounting as shown in FIG. 16B, the ejection head 4 is rotated to the position of FIG. 16A so that the front wall 4w1 (spout outlet 4a) faces the front. This completes the replacement of the ejection container 1B.

In the present embodiment, the pump 3 can be finally removed as shown in FIG. 8, as described in the ejection container 1A. In this case, the container 2 can be filled with a liquid in the container 2 by using, for example, the refill container, similarly to the ejection container 1A.

As described above, according to the present invention, the contact between the deformation suppressing portion 4b and the elastic piece 5d is released by the removal of the ejection head 4 or by the rotation of the ejection head 4. Therefore, according to the present invention, by using the ejection head 4 as an operation piece, it is possible to provide a novel ejection container to which the container 2 can be attached and detached.

Further, in each of the above-described embodiments, the cover 5 has a wall 5e arranged at a position adjacent to the deformation suppressing portion 4b, which is outside the deformation suppressing portion 4b. In this case, the cover 5 and the container 2 are kept tightly locked to each other.

Further, in each of the above-described embodiments, the container 2 has a protrusion 2c on which the claw 5c can be locked on the outer surface 2f of the mouth 2a. In this case, the cover 5 and the container 2 can be more firmly locked to each other.

Further, referring to FIG. 12, in the ejection container 1B, the side surface of the ejection head 4 has an arc shape in a plan view. In the present embodiment, the side wall 4w3 of the ejection head 4 has an arc shape with a radius of curvature r. In this case, the ejection head 4 can be rotated compactly without contacting the inner side wall 5w6 of the cover 5.

Further, the ejection containers 1A and 1B are so-called card-type spray ejection containers. In each of the above embodiments, the container 2 and the cover 5 have a flat shape. In each of the above embodiments, the container 2 is narrower in thickness of the front wall 2w1 and the rear wall 2w2 than the width of the two side walls 2w3. Further, in each of the above-described embodiments, the thickness of the front wall 5w1 and the rear wall 5w2 of the cover 5 is narrower than the width of the two outer side walls 5w3. As described above, according to the present invention, the card-type spray can be provided with a refill function by using the ejection head 4 as an operation piece.

The above description describes an exemplary embodiment of the present invention, and various modifications can be made without departing from the scope of the claims. The various configurations adopted in this embodiment and the exemplary configurations described above can be interchanged or combined as appropriate.

For example, referring to FIG. 2, in the ejection container 1A, the ejection head 4 is a rectangle having a wide width in the left-right direction in a plan view. Further, the open space R5 formed on the cover 5 is also a rectangle having a wide width in the left-right direction. In this case, as shown in FIG. 2, the ejection head 4 can be easily attached to and detached from the ejection head 4 by using the inner side wall 5w6 of the cover 5 as a guide. Further, in the case of the ejection container 1A, for example, referring to FIGS. 1 and 6, at least one of the front wall 5w1 and the rear wall 5w2 of the cover 5 can be extended to the open space R5. In the present embodiment, for example, as shown in FIGS. 1 and 6, the edge portion e5 of the front wall 5w1 and the rear wall 5w2 of the cover 5 covers the lower end portions of the front wall 4w1 and the rear wall 4w2 of the ejection head 4. In addition, it is extended to a part of the open space R5.
