Description

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 pressing head with a discharge nozzle is mounted. More specifically, the present invention relates to a pump container provided with a stopper for preventing liquid from being inadvertently discharged from the container when the container is distributed or carried.

[0002]

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

[0003] Various types of liquid discharge pumps or pump containers having such liquid discharge pumps are known, and their development and improvement are being promoted. For example, the present inventor has proposed an improved pump container 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 inadvertent liquid leakage. A pump container including the discharge pump 10 can be proposed.

The pump container shown in FIG. 7 is obtained by mounting a liquid discharge pump 10 on a container 1 having a movable inner plate 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 press-down head 12 with a discharge nozzle locked on the cap 11. Inside 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 suction path of the liquid from the container 1 to the cylinder 13, and a discharge nozzle from the cylinder 13 A discharge valve 19 is provided in the liquid discharge path 15 as a check valve for sending liquid to 18, and a spring 21 for returning the press-down head 12 with discharge nozzle to its original position when pressed down is provided. Have been.

In such a pump container, by pressing the top surface of the press-down head 12 with the discharge nozzle,
The press-down head 12 with the discharge nozzle is pushed down, and when the press is released, the press-down head 12 with the discharge nozzle returns to the original position by the bias of the spring 21, and the vertical movement of the press-down head 12 with the discharge nozzle is performed. 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 holes 22 of the press-down head 12 with discharge nozzles.

[0006] By the way, when such a pump container is filled with a liquid to produce a product and distributes the product, it is necessary to prevent the liquid from being inadvertently discharged at the time of distribution, or to use the product once by a user. Later, in order to prevent the liquid from being inadvertently discharged when carrying in a bag or the like, cover the entire top surface of the liquid discharge pump with an overcap, provide a lid on the discharge hole, provide a head and a cap. Between the head and the head operating section between the cylinders to prevent the head from being pushed down, and a pump lock mechanism consisting of a screw mechanism at the top of the cylinder to fix the head in the pushed down state. Have been.

[0007]

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

In the method in which a lid is provided in the discharge hole 22, the lid does not prevent the press-down head 12 with the discharge nozzle from being pressed down. Therefore, even if the lid is fitted in the discharge hole 22, if the discharge force of the liquid is large when the press-down head 12 with the discharge nozzle is pressed down, the lid comes off and the discharge of the liquid can be prevented. There is a problem that can not be.

In the method of mounting a stopper that prevents the pressing head 12 with the discharge nozzle from being pressed down, the discharge of new liquid due to the pressing down of the pressing head 12 with the discharging nozzle can be prevented. However, when the product is already used by the user, the liquid remains in the pump, but this liquid cannot be prevented from leaking from the discharge hole.

[0010] The pump lock mechanism can also prevent the discharge of liquid at the time of distribution before the product is started to be used. However, after the product is started to be used by the user, the pump lock mechanism is again operated by the user. It is not easy to operate the mechanism, and it is not possible to prevent the liquid staying in the pump from leaking from the discharge holes.

An object of the present invention is to solve such a problem of the prior art, and a pump container equipped with a liquid discharge pump having a press-down head with a discharge nozzle is provided.
It is an object of the present invention to prevent liquid from being inadvertently discharged during distribution, carrying, and the like.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. In each of the drawings, the same reference numerals represent the same or equivalent components.

FIG. 3 is a perspective view (FIG. 3A) of a state where the stopper 30A with a lid used in the embodiment of the present invention is not attached to a container, and FIG. FIG. 1 (b)), and FIG. 1 is a top view of the pump container 100 of the embodiment in which the stopper 30A with a lid of FIG. 3 is mounted as a stopper on the same pump container as FIG. 7 (FIG. 1 (a)). FIG. 2 is a front view (FIG. 2B), a side view (FIG. 2C), and a rear view (FIG. 2D). FIG. 2 shows a stopper 30A with a lid, and a lid of a 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 used for pumping a belt 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,
Portion between the press-down head 12 with discharge nozzles and the cap 11 when the liquid discharge pump 10 is not pressed down:
(Referred to as a head operating portion X). In addition, about a half portion in the longitudinal direction is branched by being divided into two in the thickness direction.

As shown in FIG. 1, the stopper with a lid 30A is divided in the thickness direction by being mounted on the head operating portion X of the pump container 100 in which the liquid discharge pump 10 is mounted on the container 1. The strip 31 having a length L1, which is a combination of the strip 31a which is not formed and the shorter strip 31b of the two strips divided in the thickness direction, is used as a stopper of the press-down head 12 with the discharge nozzle. (See FIG. 3). In addition, the longer one of the two strips divided in the thickness direction also functions as a stopper in the mounted state shown in the drawing, but is formed at the end of the strip 32 as described later. When the ejection hole 22 is closed by the projected portion 33, the strip 32 is detached from the head operating portion X, and does not function as a stopper. Therefore, in order to reliably obtain the function as a stopper when the stopper 30A with the lid is mounted, the length L1 of the strip 31 that always functions as a stopper at this mounting position is set as follows.
It is preferable that the length be 1/4 to the entire circumference in the circumferential direction of the head operating portion X, and it is more preferable that the length be approximately 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 such that the stopper with a cover 30A just fits into the head operating portion X.

When the stopper 30A with the lid is mounted on the head operating portion X of the pump container as a stopper, the stopper 30A with the lid has a curvature of the head operating portion X as shown in FIG. Since it has a suitable curvature, it can be easily mounted simply by fitting it into the head operating portion X.

On the other hand, a projection 33 is formed at the end of the longer one (length L2) 32 of the two strips divided in the thickness direction of the stopper 30A with the lid. The protrusion 33 serves as a lid of the discharge hole 22 as shown in FIG. That is, as shown by the broken line in FIG.
Is removed from the head operating portion X, and it is bent as shown by a dotted line to form the convex portion 33 into the discharge hole 2.
2, the protrusion 33 can function as a cover of the discharge hole 22.

Therefore, the length L2 of the band 32 is set to be at least longer than the distance from the head operating portion X to the discharge hole 22.

In the production of the band of the stopper 30A with the lid, the joining portion P of the band 32 to the band 31 serving as the stopper of the press-down head 12 with the discharge nozzle is provided.
When the belt 32 is formed to be thin so that it can be easily moved and the belt 32 itself is easily bent, the convex portion 33 at the end of the belt 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, the press-down head 12 with the discharge nozzle can be easily pushed down by fitting the band 31 as a stopper into the head operating portion X. Can be prevented, and the projection 33 of the strip 32 can be
, It is possible to prevent the liquid from leaking from the ejection holes 22. In this case, since the band 31 serving as the stopper and the band 32 having the lid 33 are integrally formed, the pump container equipped with the stopper 30A with the lid includes both the stopper and the lid. Despite the fact that it is compact and of good design.

Although the embodiment of the present invention has been described with reference to the drawings, the pump container of the present invention can take various forms. For example, as shown in FIG. 4, in the pump container of the above-described embodiment, a peripheral concave portion A corresponding to the head operating portion X is formed in a lower portion of the side surface of the container 1, and the stopper 30 </ b> A with a lid is used as a stopper. Alternatively, when used as a lid of a discharge hole, as in the above-described embodiment, this is attached as shown by a solid line, but when the stopper 30A with a lid is not used as a stopper or as a lid of a discharge hole, it is not shown in FIG. As shown by the middle broken line, the concave A
This may be inserted into the device so that it can be stored.

Further, the formation position of such a concave portion A is not limited to the lower part of the container 1 as described above. For example, as shown by a dashed line in FIG. 4, a concave portion B may be formed on the upper portion of the container 1, and a concave portion C may be formed on the cap 11.
When the recesses B and C are formed in the upper portion of the container 1 or the cap 11 in this manner, when the container 1 is used in a bathroom or the like, the recesses are used to prevent the container 1 from slipping even with hands wet with water. When the stopper 30A with a lid is fitted into B and C, the stopper 30A protrudes from the side of the container 1,
The stopper 30A with a lid fitted into the recesses B and C may function as a non-slip.

Further, regarding the configuration of the stopper 30A with the lid, in the above-described embodiment, the stopper 30A with the lid is used.
When not mounted, the band 31 serving as a stopper and the band 32 having a 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 band-shaped body serving as the stopper and the lid are continuously provided. For example, a band-like body 31 serving as a stopper and a convex portion 3 serving as a lid portion
3 is formed as an independent separate member, and the stoppers 30 with lids are connected by connecting them.
A may be configured.

A stopper 30B with a cover shown in FIG.

b) and the belt-shaped body 32 having the projection 33 serving as a lid,
It may be formed by branching up and down in parallel. In this case, when the band 32 having the convex portion 33 is bent and used as the lid of the ejection hole 22, the band 31 b which has been positioned in parallel with the band 32 having the convex portion 33 becomes the convex portion 33. The end 31c of the band 31b, which is located in parallel with the band 32 having the protrusion 33, is extended in order to prevent the band 32 having the protrusion 32 from being shifted in the direction of the initial position and reducing the effect as a stopper. It is preferable that the lower side of the band 32 having the convex portion 33 be aligned with the lower side.

A stopper 30C with a cover shown in FIG.
As described above, the band 31 having a stopper and the band 32 having the convex portion 33 serving as a lid may be branched substantially vertically.

The various stoppers 30 with lids include:
Further, in order to facilitate attachment / detachment to / from the container and insertion / removal of the lid portion 33 into / from the discharge hole 22, an anti-slip rib or a knob may be appropriately provided.
