Is a head fitted with a nozzle 3.

A dome-shaped cap-shaped cover 11 is provided by fitting a lower portion of the peripheral wall 12 to the upper portion of the container body. When the direction of liquid ejection from the nozzle is defined as the front, the cover is
It has a U-shaped concave portion 13 whose upper surface and front and rear both sides are open when viewed from the front and rear direction. The inner surface of the recess is closed by an inner wall, but an opening 14 is formed at the center of the bottom of the inner wall, and the lower end of the head 2 described above is positioned in the opening, and the upright portions 15, 15 on the left and right of the recess are formed.
The head 2 is provided between them in a forward direction.

A notch 16 is provided on the outer surface in the left-right direction of one of the standing portions 15 and 15 in the left-right direction, and the standing portion is formed as a standing portion 15a. That notch
16 is formed in an L shape when viewed from the front-rear direction, that is, formed by a standing surface and a bottom surface extending laterally from the lower end of the standing surface.

Through holes 17, 17 are formed in the left-right direction at the upper portions of the width-raised upright portion 15a and the other upright portion 15, respectively. The positions of these through holes are provided above the upper surface of the head 2. It is apparently preferable that the through hole 17 of the raised portion is penetrated in the left-right direction, while the through hole 17 of the raised portion is formed only in the upper portion of the inner wall portion and not in the upper portion of the outer wall surface of the cover. In the illustrated example, the inner surface of the upper end of the other standing portion 15 is formed as an upwardly inclining wall 18, and a through hole 17 is formed in the inclining wall.

From the outer edge of the bottom surface of the notch 16 mentioned above, a rocking plate 20 is erected via a thin hinge 19, and a guard plate 21 which is elastically deformable in the lateral direction is projected from the upper end of the rocking plate. Insert the guard plate into the through holes 17, 17. The oscillating plate 20 is preferably formed with lateral plates 22 and 22 at its front and rear ends, and upper ends of the lateral plates attached to both front and rear sides of the guard plate base so as to have a large lateral width, as shown in the figure. As shown in FIG. 1, the guard plate 21 is provided so that the top surface of the tip part is in pressure contact with the top surface of the through hole 17 by elastic deformation of the guard plate when the tip part is in the through hole 17 of the other upright portion 15. Further, as shown in FIG. 2, when the tip of the guard plate is located in the through hole 17 of the raised portion 15a, the upper surface of the tip is pressed against the upper surface of the through hole by elastic deformation of the guard plate.

FIG. 3 shows a state in which the rocking plate 20 is tilted down and the guard plate 21 is pulled out from the through holes 17 in both the upright portions.
The cover 11 is integrally molded with a synthetic resin material in this state, and then the guard plate 21 is flexed against the elasticity as shown in FIG.
It can be inserted through.

[0015]

The present invention is configured as described above, and by making it as described in claim 1, when not in use, the guard plate 21 is passed through both through holes 17, 17 as shown in FIG. The head 2 is not inadvertently pushed down, and when in use, the swing plate 20 is tilted outward as shown in FIG. 2 to move the tip of the guard plate into the through hole 17 of the width rising portion 15a. It is possible to push down the head and the guard plate 21 can be moved via the swing plate 20, so that the operation is easy. Swing plate
Since 20 is erected from the bottom surface of the notch 16 provided outside the width rising portion 15a, the oscillating plate 20 can be placed within the range of the notch 16 and the oscillating plate 20 covers the cover 11. It does not get out of the way by protruding to the outside.

According to claim 2, the guard plate 21
It is possible to prevent the upper end of the head 2 from being opened due to the frictional resistance between the upper surface of the leading end of the above and the upper surface of the through hole 17 of the other standing portion 15 and the tip of the guard plate accidentally coming out of the through hole 17 of the other standing portion.

According to the present invention, the tip of the guard plate can be kept in contact with the upper surface of the through hole 17 of the width rising portion 15a by frictional resistance, and the tip of the guard plate moves to the upper part of the head. Therefore, there is no trouble that the pushing down of the head is hindered and the tip of the guard plate comes out of the through hole 17 and needs to be reinserted.

By forming as in claim 4, both through holes are formed.
Even when the guard plate 21 is inserted into the inside of the 17, 17, the upper part of the rocking plate 20 formed to be wide is located outside the through hole 17 of the raised upright portion, so that it is wide. The operation of pulling out and inserting the guard plate 21 by holding the upper part of the swing plate becomes easy.
