DESCRIPTION OF THE PREFERRED EMBODIMENTS 1 is a head-pressing type liquid ejection container. The liquid ejection container may be of a known pump type or aerosol type. The illustrated example is a pump-type liquid ejection container, 2 is a container main body having a concave groove 3 provided around the upper end of the body, 4 is a mounting cylinder screwed to the neck of the container main body, 5
Is a head having a nozzle hole 6 opened on the front surface of the upper part, which is fitted to the upper end of the stem which is urged upward from the cylinder vertically installed in the container body, and has an engaging groove in the front-rear direction on its upper surface. 7 is drilled.

Reference numeral 10 denotes a cap fitted to the upper part of the container body, and the cap comprises a cap body, a bent plate member, and a slide plate.

The cap body 11 has a convex strip 13 provided on the inner surface of the lower end of the peripheral wall 12 fitted in the concave groove 3. An opening 15 is continuously formed from the rear portion of the top wall 14 that closes the upper end surface of the peripheral wall to the lower portion of the front surface of the peripheral wall through the upper end of the front portion of the peripheral wall. Recesses 16, 16 for engaging an outer plate of a slide plate, which will be described later, are formed on both left and right sides of the top wall 14 excluding both front and rear parts.

The bending plate member 20 is provided with a trigger 22 projecting from a front end of a horizontal plate 21 that closes the opening portion of the top wall obliquely downward and forward. A liquid passage window hole 23 is formed. Its a horizontal plate 21
The rear part is pivotally attached to the rear part of the peripheral wall by a pin 24, and as shown in FIG. 4, elongated notches 25, 25 are formed on both left and right sides of the front part, and a short notch 26, 26 is formed at the front end of the elongated notch. 26 are drilled respectively. The short cutout may be provided at the rear end. Further, from the lower surface of the horizontal plate 21, first engaging plates 27, 27 which engage with the left and right inner surfaces of the engaging groove 7 on the upper surface of the head 5 are hung down, and by the engagement, the horizontal plate 21, and hence the window hole 23 of the trigger. When the trigger 22 is pulled downward and rearward while the rotation of the head 5 with respect to the head is stopped, the lower ends of the first engaging plates 27, 27 come into contact with the bottom surface of the engaging groove to press down the head 5, and the head is pressed by the pressing down. Nozzle hole 6
The liquid can be jetted from the nozzle, and the liquid can be jetted forward through the window hole 23 in the upper part of the trigger.

The rotation preventing means of the head 5 is, for example, a vertical groove in the guide cylinder 4a rising from the mounting cylinder 4 screwed to the neck portion of the container body and the head 5, and vertically moved in the vertical groove. It can be formed with an engaging element, and various other means are conceivable.

The slide plate 30 is engaged with the recesses 16, 16 of the cap body described above from the left and right sides of the upper plate 31 placed on the upper surface of the front part of the cap body and the horizontal plate 21, and the outer plate 32,
The second engaging plates 33, 33 are hung by inserting the second engaging plates 33, 33 into the elongated notches 25, 25 already described. The second engagement plate engages the first engagement protrusions 34, 34 on its outer surface with the lower inner edge of the top wall 14 and the front inner surface of the second engagement plate with the lower edge of the horizontal plate 21, and has a short cutout 26. , 26 are provided with second engaging projections 35, 35 having a size capable of passing through the inside.

In the above structure, if the trigger operation is disabled, that is, if a safety device is desired, the slide plate 30 is moved backward as shown in FIG. The second engaging projections 35, 35 on the inner surfaces of the second engaging plates 33, 33 hanging from the slide plate 30 at the rearward moving position engage with the lower inner edges of the elongated cutouts 25, 25 of the horizontal plate to form the horizontal plate. 21 Front descent, and therefore trigger 22
It is impossible to pull the bot down.

When removing the above-mentioned safety device, FIG. 2 and FIG.
As shown in FIG. 5, the slide plate 30 may be pulled out to the front end, and at this time, the second engagement protrusions 35, 35 are located below the short cutouts 26, 26, so that the trigger 22 is moved downward and rearward from that state. When pulled, the front part of the horizontal plate 21 descends without being obstructed by the second engaging projections 35, 35 due to the swinging of the bending plate member 20 around the pin 24, and the first engaging plates 27, 27. Pushes down the head 5 to eject the liquid through the window 23.

When the short cutouts 26, 26 are provided at the rear ends of the elongated cutouts 25, 25, the safety device is removed by pushing the slide plate 30 backward, and the safety device is provided by pulling it forward. Will be done.

[0015]

The present invention is configured as described above, and is formed by the head-pressing type liquid ejection container 1 and the cap 10 with a trigger fitted to the upper part of the container body of the container. The trigger-type liquid ejection container can be made by simply fitting the above-mentioned cap to the head-down type liquid ejection container. Therefore, the manufacturer can use the head-down-type liquid ejection container as it is or as a trigger type by ejecting the cap. Since it can be shipped, the cost can be reduced due to the effect of mass production.

According to the first aspect of the present invention, the first engaging projections 34, 34 on the outer surface of the second engaging plates 33, 33 hanging from the slide plate 30 placed on the upper surface of the cap main body and the horizontal plate are attached to the cap main body. By engaging the lower inner edge of the top wall 14 and engaging the second engaging protrusions 35, 35 on the inner surface of the second engaging plate with the lower edge of the horizontal plate 21, the trigger 22 can be located in either the upper front or the lower rear. Even if the slide plate 30 is slid to move the second engaging protrusions 35, 35 downwardly through the short cutouts 26, 26,
Since the trigger can be operated, the operation of the safety device can be performed extremely easily and reliably.

In the case of the second aspect of the present invention, in addition to the above effects, the engaging groove 7 and the horizontal plate 21 formed on the upper surface of the head are provided.
A first engagement plate vertically extending from the lower surface and engaged in the engagement groove.
27 and the rotation of the head is blocked and the first engaging plate
Since the head 5 is pushed down by the horizontal plate by pulling the trigger 22 through the 27, there is an effect that the first engaging plate can perform both functions.
