[0011]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 4 shows an embodiment of the discharge container according to the present invention. The illustrated container 21 has a cap 24 fixed to the mouth 23 of the container main body 22 by screwing, a cylinder 25 attached to the cap 24 and extending inside the container main body 22, and a vertical movement into the cylinder 25. A hollow stem 26 extending as much as possible, and a valve body housed in the cylinder 25
27, a piston 28 fitted to the stem 26, and a head with a nozzle having a nozzle 29 fitted to the upper end of the stem 26.
30 and a spring 31 interposed between the head with nozzle 30 and the cap 24.

Here, the stem 26 is composed of a first member 26A fitted to the nozzle-mounted head 30 and a second member 26B fitted to the inner surface thereof. It is slidably held. A holding portion 32 is provided near the lower end of the second member 26B of the stem 26, and the upper end of the valve body 27 is held by the holding portion 32. A guide plate 33 is provided at a lower portion of the valve body 27 to guide the liquid contents sucked into the cylinder 25 and flow, and a temporary difference with a stopper 35 described later is provided by a step provided at the upper portion of the guide plate 33. Performs the function of maintaining the set state. Further, a suction pipe 34 is attached to a lower portion of the cylinder 25. In addition, valve body 27
Is equivalent to the valve element 7 in the container 1 of FIG.

In the present container 21, a stopper 35 is further provided in the cylinder 25. The stopper 35 holds the attitude and position of the valve body 27 in the cylinder 25 as described later, and regulates the stroke of the head 30 with the nozzle.

FIG. 5 shows the stopper 35, FIG. 5 (a) shows its outer shape, FIG. 5 (b) shows a vertical section, and FIG. 5 (c)
FIG. 6 is a sectional view taken along line AA in FIG. As shown, the stopper 35 has a hollow cylindrical shape, and two ribs 36 are formed on the outer periphery. The rib 36 is for reducing the contact area between the stopper 35 and the stopper 35 when the stopper 35 is housed in the cylinder 25, thereby reducing the frictional resistance. As shown in FIGS. 5B and 5C, the inner surface of the stopper 35 includes an undercut for maintaining the temporarily set state in cooperation with the step provided above the guide plate 33, and a ring. A hollow hole 37 is provided, through which the valve body 27 is inserted. The upper and side surfaces of the guide plate 33 abut against the ring end surface of the stopper 35 and the inner surface of the stopper 35, so that the valve body 27 can be more reliably prevented from falling down. Around the hole 37, a plurality of flow paths 38 for flowing the contents of the container 21 are provided. Further, as will be described later, the height H of the stopper 35 depends on the head 30 with the nozzle of the container 21.
It has the function of regulating the stroke of the vehicle. The shape of the portion where the upper surface of the guide plate abuts is not necessarily a ring, and various shapes such as a rib extending from the inner surface of the stopper can be selected.

FIG. 6 shows a state in which the valve body 27 is
This shows the procedure for setting the camera together with 35. First, FIG.
As shown in (a), the step provided in the upper part of the guide plate of the valve body 27 passes over the undercut on the inner surface of the stopper 35 and the valve body
27 is inserted and provisionally set in the stopper 35, and placed in the cylinder 25 in that state. As shown in FIG. 6B, the valve body 27
The position and the upright posture are held by the stopper 35. Therefore, the stem 26 can be continuously set in the cylinder 25 without holding the position and posture of the valve body 27 by other members, tools, and the like.

As described above, the stopper 35 not only keeps the position and posture of the valve body 27 in the cylinder, but also has the function of defining the stroke of the head 30 with nozzle.
FIGS. 7A and 7B show this, in which FIG. 7A shows a state where the head with nozzle 30 is not pushed down, and FIG. 7B shows a state where it is pushed down. Here, the container body 22 is omitted.

From the state shown in FIG. 7 (a), the user pushes down the nozzle-equipped head 30 in order to discharge the contents of the container body (not shown). At this time, the stem 26 and the piston 28 also descend together with the nozzle-equipped head 30, but when the lower end of the second member 26B of the stem 26 contacts the upper end of the stopper 35,
The nozzle-equipped head 30 can no longer be depressed. That is, the stroke L of the head 30 with nozzle is
As is apparent from the figure, the height is regulated by the height H of the stopper 35. This means that the amount of contents discharged by the pump action of the nozzle-equipped head 30 is always kept constant. In other words, by appropriately setting the height H of the stopper 35, the user can always discharge and use an appropriate amount of the content from the container 21.

As described above, the discharge container according to the present invention is provided with the stopper for stably maintaining the position and the posture of the valve element in the cylinder at the time of assembly. By appropriately setting the height of the stopper, the stroke amount of the nozzle-equipped head can be regulated, whereby the discharge amount can be easily changed only by replacing the stopper member. Can be changed, and an appropriate amount of contents can always be discharged.

The present invention is not limited to the above embodiment, but can be applied to other types of discharge containers having the same configuration. Also, two or more ribs 36 provided on the outer surface of the stopper 35 shown in FIG. 5 can be provided.
