Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pump container in which a liquid discharge pump having a push-down head with a discharge nozzle is mounted on the container. More specifically, the present invention relates to a pump container provided with a stopper that prevents the liquid from being accidentally discharged from the container when the container is in circulation, carried, or the like.

[0002]

2. Description of the Related Art Conventionally, as one of pump containers provided with a pump for discharging a liquid in a container, there is known one in which a liquid discharge pump having a pressing head with a discharge nozzle is mounted on the container. This liquid discharge pump is a vertical push type liquid discharge pump that sucks liquid from a container into the pump by pushing down a pressing head with a discharge nozzle and discharges the liquid from the discharge nozzle.

Various types of such liquid discharge pumps or pump containers equipped with such liquid discharge pumps are known, and their development and improvement are in progress. For example, the present inventor has proposed a liquid pump as shown in FIG. 7 as an improved pump container capable of improving the liquid tightness of a container equipped with a liquid discharge pump and preventing accidental liquid leakage. A pump container equipped with the discharge pump 10 can be proposed.

In the pump container of FIG. 7, a liquid discharge pump 10 is mounted on a container 1 having a movable inner tray 2. In this case, the liquid discharge pump 10 includes a cap 11 attached to the mouth and neck of the container 1 and a push-down head 12 with a discharge nozzle locked on the cap 11. In the pump 10, a cylinder 13, a piston 14 that moves up and down in the cylinder, a suction valve 16 provided as a check valve in a liquid suction path from the container 1 to the cylinder 13, and a discharge nozzle from the cylinder 13 are provided. A discharge valve 19 provided in the liquid discharge passage 15 as a check valve when the liquid is sent to 18, and a spring 21 for returning the push-down head 12 with a discharge nozzle to its original position when the push-down head 12 is pushed down are provided. Has been.

In such a pump container, by pressing the top surface of the push-down head 12 with a discharge nozzle,
The push-down head 12 with the discharge nozzle is pushed down, and when the push is released, the push-down head 12 with the discharge nozzle returns to the original position by the bias of the spring 21, and the push-down head 12 with the discharge nozzle moves up and down. Accordingly, the piston 14 also moves up and down, whereby the liquid in the container 1 is sucked by the liquid discharge pump 10 and discharged from the discharge hole 22 of the push-down head 12 with a discharge nozzle.

By the way, when such a pump container is filled with a liquid to make a product and the product is circulated, in order to prevent the liquid from being inadvertently discharged at the time of distribution, or the user once used the product. After that, in order to prevent the liquid from being accidentally discharged when carrying it in a bag etc., cover it with an overcap that covers the entire top surface of the liquid discharge pump, provide a lid on the discharge hole, and remove the head and cap. Between the head operation part, a stopper that prevents the head from being pushed down is provided, and a pump lock mechanism that consists of a screw mechanism at the top of the cylinder is provided so that the head can be fixed in the depressed state. Has been done.

[0007]

However, among the methods for preventing the inadvertent ejection of liquid, in the method using an overcap, the ejection nozzle 18 is lengthened so that the ejection nozzle 18 protrudes outside the container body. When forming, the shape of the overcap becomes complicated and becomes large, so that there is a problem that the designability is poor.

In the method of providing the discharge hole 22 with the lid, the lid does not prevent the pushing down head 12 with the discharge nozzle from being pushed down. Therefore, even if the lid is fitted in the ejection hole 22, if the ejection force of the liquid is large when the pressing head 12 with the ejection nozzle is pushed down, the lid will come off and the ejection of the liquid can be prevented. There is a problem that you cannot do it.

By the method of mounting the stopper that prevents the pressing down head 12 with the discharge nozzles from being pressed, it is possible to prevent the discharge of new liquid by the pressing down of the pressing head 12 with the discharge nozzles. However, if the product has already been used by the user, it is impossible to prevent the liquid from leaking out from the discharge hole even though the liquid remains in the pump.

The pump lock mechanism can prevent the liquid from being discharged at the time of distribution before the product is started to be used, but after the product is started to be used by the user, the user can lock the pump again. It is not easy to operate the mechanism, and it is also impossible to prevent the liquid retained in the pump from leaking out from the discharge hole.

The present invention is intended to solve the problems of the prior art as described above, and in a pump container equipped with a liquid discharge pump having a pressing head with a discharge nozzle,
An object of the present invention is to prevent the liquid from being inadvertently discharged at the time of distribution, carrying, etc.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be specifically described below with reference to the drawings. In each drawing, the same reference numerals represent the same or equivalent constituent elements.

FIG. 3 is a perspective view of the stopper 30A with a lid used in the embodiment of the present invention in a state where it is not attached to the container (FIG. 3A) and a perspective view when the stopper 30A is spread on a plane (the same). FIG. 1B is a top view of the pump container 100 of the embodiment in which the stopper 30A with the lid portion of FIG. 3 is mounted as a stopper on the same pump container as FIG. 7 (FIG. 1A). FIG. 2 is a front view (the same figure (b)), a side view (the same figure (c)), and a rear view (the same figure (d)). FIG. 2 shows a stopper 30A with a lid and a lid of the discharge hole. It is explanatory drawing in the case of making it function as.

The stopper 30A with a lid shown in FIG. 3 is a belt-shaped body made of polyolefin, polyester, nylon, polystyrene, polycarbonate, vinyl chloride, polyvinyl alcohol, vinylidene chloride, etc., alone, blended, or laminated. The mounting site of the container (ie,
A portion between the pressing head 12 with a discharge nozzle and the cap 11 when the liquid discharge pump 10 is not pressed down:
It is shaped to have a curvature that matches the curvature of the peripheral wall of the head operating portion X). Further, about 1/2 of the part in the longitudinal direction is branched by being divided into two in the thickness direction.

As shown in FIG. 1, the stopper 30A with the lid portion is divided in the thickness direction by being attached to the head operating portion X of the pump container 100 in which the liquid discharge pump 10 is attached to the container 1. The strip-shaped body 31 having a length L1 which is a combination of the strip-shaped body 31a which is not formed and the strip-shaped body 31b which is the shorter one of the two strip-shaped bodies which is divided in the thickness direction is the stopper of the pressing head 12 with the discharge nozzle. (See FIG. 3). The longer strip 32 of the two strips divided in the thickness direction also functions as a stopper in the mounted state in the same figure, but is formed at the end of the strip 32 as described later. When the ejection hole 22 is closed by the convex portion 33 that is formed, the belt-shaped body 32 is removed from the head operating portion X and does not function as a stopper. Therefore, in order to surely obtain the function as the stopper when the stopper 30A with the lid is attached, the length L1 of the belt-like body 31 which always functions as the stopper at this attachment position is
The circumference of the head operating portion X is preferably 1/4 to the entire circumference, and more preferably about 1/2 to 2/3.
Further, it is preferable that the width W1 is appropriately determined according to the height h of the head operating portion X so that the stopper 30A with the lid portion is just fitted into the head operating portion X.

Further, when the stopper 30A with the lid portion is mounted on the head operating portion X of the pump container as a stopper, the stopper 30A with the lid portion has the curvature of the head operating portion X as shown in FIG. 3 (a). Since it has a suitable curvature, it can be easily mounted only by fitting it into the head operating unit X.

On the other hand, a convex portion 33 is formed at the end of the longer strip (length L2) 32 of the two strips divided in the thickness direction of the stopper with stopper 30A. The convex portion 33 serves as a lid portion of the discharge hole 22 as shown in FIG. That is, as shown by the broken line in FIG.
The strip-shaped body 32 having the above is removed from the head operating portion X, and is further bent as shown by a dotted line to form the convex portion 33 into the ejection hole 2.
The protrusion 33 can be made to function as a lid of the ejection hole 22 by fitting the protrusion 33 into the discharge hole 22.

Therefore, the length L2 of the strip 32 should be at least longer than the distance from the head operating portion X to the ejection hole 22.

Further, when the strip-shaped body of the stopper 30A with the lid portion is manufactured, the joint portion P of the strip-shaped body 32 to the strip-shaped body 31 serving as the stopper of the push-down head 12 with the discharge nozzle is formed.
When the belt-shaped body 32 is formed thin so that the belt-shaped body 32 can be easily moved, and the belt-shaped body 32 itself is also formed to be easily bent, the projection 33 at the end of the belt-shaped body 32 is fitted into the discharge hole 22. In doing so, it becomes easy to bend the strip 32.

As described above, in the pump container of the present invention having the stopper 30A with the lid portion, the strip-shaped body 31 is fitted into the head operating portion X as a stopper to easily push down the pushing head 12 with the discharge nozzle. Can be prevented, and the convex portion 33 of the band-shaped body 32 can be connected to the discharge hole 22.
It is possible to prevent the liquid from leaking from the ejection hole 22 by fitting it into the. In this case, since the belt-shaped body 31 that serves as a stopper and the belt-shaped body 32 having the lid portion 33 are integrally formed, the pump container equipped with the stopper 30A with the lid portion includes both the stopper and the lid portion. However, it has a compact and excellent design.

Although the embodiment of the present invention has been described above with reference to the drawings, the pump container of the present invention can take various modes other than the above. For example, as shown in FIG. 4, in the pump container of the above-described embodiment, a circumferential recess A corresponding to the head operating part X is formed in the lower part of the side surface of the container 1, and the stopper 30A with a lid is used as a stopper. Alternatively, when it is used as the lid of the discharge hole, it is mounted as shown by the solid line in the same manner as the above-mentioned embodiment, but when the stopper 30A with the lid is not used as the stopper or the lid of the discharge hole, As indicated by the middle broken line, the recess A
It may be inserted into and stored.

The formation position of such a recess A is not limited to the lower portion of the container 1 as described above. For example, as shown by the alternate long and short dash line in FIG. 4, the recess B may be formed in the upper portion of the container 1, or the recess C may be formed in the cap 11.
When the recesses B and C are formed in the upper portion of the container 1 or the cap 11 as described above, the recesses are formed in order to prevent the container 1 from slipping even when the container 1 is wet with water when the container 1 is used in a bathroom or the like. When the stopper 30A with the lid portion is fitted into B and C, it is projected from the side surface of the container 1,
The stopper 30A with a lid fitted in the recesses B and C may function as a slip stopper.

Regarding the structure of the stopper 30A with the lid, the stopper 30A with the lid is used in the above-described embodiment.
When not attached, the strip-shaped body 31 serving as a stopper and the strip-shaped body 32 having the convex portion 33 serving as a lid are integrally formed so as to overlap in parallel as shown in FIG. Can take various forms as long as the strip-shaped body that serves as a stopper and the lid are provided in series. For example, the strip-shaped body 31 that serves as a stopper and the convex portion 3 that serves as a lid portion
