Even in a stationary dispenser, there are cases where it is desired to change the direction of liquid discharge. For example, when trying to receive the discharged liquid in another container such as a cup, depending on the shape and size of the container, it may not be possible to properly place the container right below the nozzle. Difficulties also arise when the container on the dispenser side is large.

The device of Patent Document 2 is a device used for a handheld spray type dispenser, and cannot be used as is for a stationary type dispenser like Patent Document 1.
In addition, both the devices of Patent Document 2 and Patent Document 3 are basically used for a dispenser that discharges liquid in a horizontal direction, and can be used as they are in a pump dispenser that discharges a liquid downward like Patent Document 1. It is not possible.

The present invention was developed in response to the above-mentioned problems. That is, an object of the present invention is to provide a stationary type pump dispenser that discharges liquid downward, which can change the direction of liquid discharge.

As a result of extensive studies, the inventor of the present invention found that the direction of liquid discharge can be changed by making the nozzle of the pump dispenser a movable nozzle equipped with a downwardly directed nozzle opening and an extension hose section. The present invention is based on this knowledge.

The present invention is a pump dispenser A equipped with a movable nozzle 1 capable of changing the discharge direction of liquid, and includes a container 2 for storing liquid and a dispenser section 3 attached to the container 2. The part 3 includes a cylindrical cylinder part 4, a piston shaft part 5 that slides inside the cylinder part 4, a nozzle head part 6 attached to the upper end of the piston shaft part 5, and a nozzle head part 6 attached to the lower part of the cylinder part 4. The movable nozzle 1 provided at the tip of the nozzle head section 6 has a first valve FV with a first valve FV attached to the nozzle head section 6, and a second valve SV mounted on the nozzle head section 6. The pump dispenser A consists of a bendable extension hose section 12 attached via a connecting spout 13 to the pump dispenser A.

The present invention resides in the pump dispenser A described above, in which at least a portion of the extension hose portion 12 is bellows-shaped.

The present invention resides in the pump dispenser A described above, in which the length L1 of the extension hose portion 12 is shorter than the distance L2 from the nozzle opening 11 to the piston shaft portion 5.

The present invention resides in the pump dispenser A described above, in which the extension hose portion 12 is fixed to the connection spout 13, and the connection spout 13 is press-fitted into the nozzle port 11.

The present invention resides in the pump dispenser A described above, in which the spring body of the second valve SV mounted on the nozzle port 11 is held in a compressed state by press-fitting and fixing the connecting spout 13.
Further, the present invention may be an appropriate combination of the above configurations.

The pump dispenser A of the present invention is equipped with a movable nozzle 1 provided at the tip of a nozzle head section 6, and the movable nozzle 1 is composed of a nozzle port 11 that opens downward, and an extension hose section 12 attached to the nozzle port 11. This allows the direction of liquid discharge to be changed freely.
In addition, in the pump dispenser A that is a stationary type and discharges liquid downward, it is necessary to push down the nozzle with one hand to discharge the liquid, but the movable nozzle 1 is attached to the nozzle opening 11 and the nozzle 1 is attached to the nozzle opening 11. The extended hose portion 12 allows easy operation with the other hand.

In the pump dispenser A, since at least a portion of the extension hose portion 12 is bellows-shaped, the direction of liquid discharge can be changed with a simple configuration.
Further, when the extension hose section 12 is made of a material having a certain hardness, it is possible to maintain the state in which the liquid discharge direction is changed without applying force to the extension hose section 12.

In the pump dispenser A, the length L1 of the extension hose portion 12 is shorter than the distance L2 from the nozzle port 11 to the piston shaft portion 5, so that when attempting to change the direction of liquid discharge, unexpected Even if the extension hose part 12 is operated incorrectly, the tip of the extension hose part 12 can be prevented from hitting the piston shaft part 5. Therefore, even if the liquid is accidentally discharged, the piston shaft portion 5 can be prevented from becoming contaminated with liquid.

In the pump dispenser A, the extension hose part 12 is fixed to the connection spout 13, and the connection spout 13 is press-fitted into the nozzle port 11, so that the extension hose part with a different diameter can be adjusted by selecting the connection spout 13. 12 can be easily attached to the nozzle opening 11, which is extremely useful.

In the pump dispenser A, the spring body of the second valve SV attached to the nozzle port 11 is held in a compressed state by press-fitting and fixing the connecting spout 13, so that the spring body of the second valve itself is directly brought into the compressed state. It has the advantage of not having to be installed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings as necessary.
In addition, in the drawings, the same elements are given the same reference numerals, and overlapping explanations will be omitted.
In addition, the positional relationships such as top, bottom, left, and right are based on the positional relationships shown in the drawings unless otherwise specified. Furthermore, the dimensional ratios in the drawings are not limited to the illustrated ratios.

FIG. 1 is a sectional view illustrating a pump dispenser A.
The pump dispenser A of the present invention is used stationary and, in principle, discharges liquid downward.
The pump dispenser A of the present invention includes a container 2 containing a liquid and a dispenser section 3 attached to the container 2. The container 2 and the dispenser part 3 are attached by screwing together the opening of the container 2 and the cap part provided on the dispenser part 3.

FIG. 2 is a sectional view illustrating the movement of the dispenser section 3.
The dispenser part 3 includes a cylindrical cylinder part 4, a piston shaft part 5 that slides inside the cylinder part 4, a nozzle head part 6 attached to the upper end of the piston shaft part 5, and a nozzle head part 6 attached to the lower part of the cylinder part 4. The first valve FV is mounted on the nozzle head part 6, and the second valve SV is mounted on the nozzle head part 6.

The cylinder portion 4 has a cylindrical shape with a reduced diameter on the lower end side, and has a first valve seat SVS for mounting the first valve FV on the lower inside thereof.
Furthermore, a flange portion extending outward from the cylinder portion 4 is provided on the outer upper side of the cylinder portion 4 .
Moreover, a bottomed cylindrical chap-lit part 7 is provided further above the flange part.
A hole is provided in the center of the chap-lit portion 7, and a piston shaft portion 5, which will be described later, can slide through the hole.
Moreover, a female thread is cut on the inner side surface of the hole, so that it can be screwed into a nozzle head section 6, which will be described later.

The piston shaft portion 5 has a hollow cylindrical shape and is slidable in the vertical direction within the cylinder portion 4.

Further, the lower end side of the piston shaft portion 5 has a tapered diameter and is provided with a plurality of slits.
Thereby, when the piston shaft portion 5 slides within the cylinder portion 4 and reaches the bottom dead center, it becomes possible to elastically press the first valve FV against the first valve seat SVS.
Further, the liquid within the cylinder portion 4 is allowed to flow into the piston shaft portion 5.

The nozzle head section 6 is provided at the upper end of the piston shaft section 5 and extends laterally so as to be orthogonal to the piston shaft section 5.
The nozzle head section 6 has a receiving base, a lid section, and a nozzle section. The receiving base and the lid are connected at the end on the piston shaft section 5 side via a hinge section.
This allows the lid to be opened and closed relative to the receiving base.

The receiving base is a bottom plate having two holes: a piston shaft side inlet which is a hole communicating with the inside of the piston shaft part 5, and a nozzle side outlet which is a hole communicating with the nozzle part located a certain distance away from the piston shaft side inlet. and a receiving base side standing wall part formed on the bottom plate part so as to stand up so as to surround the nozzle side discharge port and the piston shaft part 5 side entrance.

Further, the lid portion includes a ceiling plate portion, a lid-side standing wall portion that stands up on the ceiling plate portion, and a cover wall portion provided on the outside thereof.
When the lid is closed with respect to the receiving base, a flow path communicating from the piston shaft portion 5 to the nozzle portion is formed between the lid portion and the receiving base, and has a piston shaft side inlet and a nozzle side discharge port. It is formed by a receiving base side standing wall part and a receiving base side standing wall part surrounding these.

That is, the flow path between the lid and the receiving base is surrounded by the double wall of the receiving base-side vertical wall and the lid-side vertical wall.
This makes it possible to prevent liquid from flowing out even if one of them is damaged.
Further, since the lid part can be opened and closed with respect to the receiving base, it is possible to open the lid part and clean the flow path easily.

The nozzle part has a cylindrical shape and communicates with the nozzle-side discharge port of the receiving base. The nozzle portion is provided facing downward at the end opposite to the hinge portion.
Further, a second valve SV is attached to the nozzle portion.
The second valve SV presses the second valve seat SVS, which is a wall surface defining the nozzle-side discharge port, upward by its elastic force.
When the second valve SV closes the second valve seat SVS, it becomes possible to reliably shut off the liquid remaining in the nozzle head portion 6 from the outside, and it is possible to prevent deterioration of the liquid.

A male screw is cut at the lower end of the nozzle head section 6, and is provided so that it can be screwed into the chap-lit section 7 described above. By screwing the nozzle head part 6 and the chap-lit part 7 together, it becomes possible to suppress sliding of the piston shaft part 5. Thereby, when discharging the liquid is not necessary such as during storage, it is possible to prevent the pump dispenser A from being accidentally touched and discharging the liquid by mistake.

FIG. 3 is a perspective view showing the connection spout 13 and the extension hose part 12 of the movable nozzle part 1, in which (A) shows the connection spout 13 and (B) shows the extension hose part 12.
The nozzle head section 6 has a movable nozzle 1 provided at a nozzle section at the tip thereof.
The movable nozzle 1 includes a nozzle port 11 communicating with the piston shaft portion 5 and opening downward, and an extension hose portion 12 attached to the nozzle port 11.

FIG. 4 is a sectional view showing the connection spout 13 and the extension hose part 12, and (A) is
(B) shows a state in which both are not fixed, and (B) shows a state in which both are fixed and integrated.
The extension hose section 12 has a cylindrical shape, and its central portion is provided in a bellows shape. By deforming the bellows-shaped portion, the direction of the extension hose portion 12 changes. Therefore, the direction of liquid discharge can be changed with a simple configuration.
The movable nozzle 1 attached to the tip of the nozzle head section 6 includes a bendable extension hose section 12, which is housed inside the nozzle opening 11.
The extension hose portion 12 is press-fitted into the nozzle port 11 via a connection spout 13 having a center hole.
This connection spout 13 is a part that is interposed when the extension hose part 12 is attached to the nozzle port 11 and serves as a connection between the two.
The extension hose portion 12 is inserted into the center hole of the connection spout 13 to fix them together, and as the fixing means, for example, ultrasonic welding is employed.
When polypropylene resin is used as the material for the extension hose portion 12 and the connection spout 13, they can be efficiently fixed by ultrasonic welding.
Here, for example, in order to attach the extension hose part 12 with a large diameter to the nozzle port 11, it is sufficient to attach it to the nozzle port by fixing it to a connection spout with a larger center hole.
By selecting the connecting spout 13, extension hose sections 12 having different diameters can be easily attached to the nozzle port 11, which is extremely useful.
As described above, the extension hose part 12 can be attached to the nozzle port 11 by simply press-fitting the connection spout 13, which is integrated with the extension hose part 12, into the nozzle port 11, so the assembly is efficient. be.

FIG. 5 is an enlarged sectional view illustrating the movable nozzle 1 in the nozzle head section 6. As shown in FIG.
By the way, the present invention has another advantage that the spring body of the second valve SV can be assembled in a compressed state by the movable nozzle part 1.
By attaching the connecting spout 13 integrated with the movable nozzle part 1, more specifically, the extension hose part 12, to the nozzle port 11, the upper end of the connecting spout 13 pushes up the spring body, more specifically, the seat part SVa of the spring body. The spring body can be put into a compressed state.
Note that the fact that the spring body is in a compressed state means that the valve body SVB is pressed upward by the spring body and is in pressure contact with the valve seat SVS.
In this case, there is an advantage that it is not necessary to directly attach the spring body of the second valve SV in a compressed state.
That is, in order to attach the spring body itself in a compressed state, it is necessary to give the inner wall of the nozzle port 11 a fine special shape that matches the spring body, which is no longer necessary.

The extension hose portion 12 is made of resin having a certain hardness. This makes it possible to maintain the changed liquid discharge direction without applying any force to the extension hose section 12.

The extension hose portion 12 can change the direction of its tip while maintaining connection to the nozzle port 11.
When it is desired to change the direction of liquid discharge in the pump dispenser A, change the direction of the extension hose section 12 in advance, or place your hand on the extension hose section 12 and press down the nozzle section with the direction fixed.

Here, the discharge of liquid by the pump dispenser A will be described.
When the cylinder section 4 and the cylinder section 4 connected thereto are at the top dead center, the inside of the nozzle head section 6, the inside of the cylinder section 4, and the inside of the piston shaft section 5 are filled with liquid. At this time, by pushing down the nozzle part, the pressure in the space filled with these liquids increases, and liquid pressure is applied to the first valve FV and second valve SV, pushing both of them downward. As a result, the first valve FV is closed and the second valve SV is opened. Therefore, liquid is discharged to the outside from the nozzle port 11 and the extension hose portion 12 communicating therewith.

At this time, since a part of the extension hose part 12 is formed of a resin having a bellows shape and a certain hardness, the discharge direction can be changed freely.

When the liquid pressure in the nozzle head section 6, cylinder section 4, and piston shaft section 5 decreases due to the discharge of the liquid, the downward pressure applied to the first valve FV and the second valve SV is released. This opens the first valve FV and closes the second valve SV.
Therefore, the discharge of the liquid to the outside is interrupted, and the liquid flows into the piston shaft portion 5 from the container 2.

When the nozzle part is pushed up again to pour out the liquid and reaches the top dead center, the inside of the nozzle head part 6, the cylinder part 4, and the piston shaft part 5 become negative pressure, and the pressure flows through the first valve FV. Liquid is sucked up from inside the container 2 into these spaces.

Further, the length L1 of the extension hose portion 12 is formed shorter than the distance L2 from the nozzle opening 11 to the piston shaft portion 5. Therefore, when the direction of the extension hose part 12 is changed as shown in FIG. 5, even if the extension hose part 12 is operated incorrectly, the tip of the extension hose part 12 is prevented from hitting the piston shaft part 5. can do. Further, even if the liquid is accidentally discharged, it is possible to prevent the vicinity of the chap lit portion 7 from becoming contaminated with liquid.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments.

In the embodiments described above, the central portion of the extension hose portion 12 is bellows-shaped, but the entire extension hose portion 12 or the ends thereof may be bellows-shaped.
Alternatively, it may have a simple cylindrical shape. In this case, it becomes possible to reduce the number of manufacturing steps.

In the above embodiment, the extension hose portion 12 is made of a resin having a certain hardness, but it may be made of a resin having flexibility. In this case, the liquid discharge can be changed with less force, and even a person with weak strength such as a child can easily handle the liquid.

In the embodiments described above, the extension hose section 12 is attached to the nozzle port 11 by being attached to the nozzle section, but the present invention is not limited thereto. For example, it may be inserted into the nozzle opening 11, or it may be inserted through a packing or the like, or a mounting device or the like may be used.
In this case, the attachment of the extension hose part 12 to the nozzle port 11 can be made stronger, and it becomes possible to prevent liquid leakage.

In the pump dispenser A of the present invention, the container 2 is not limited. For example, it is possible to suitably use a container 2 made of resin, a pail can, or the like.

In the above embodiment, the length L1 of the extension hose section 12 is shorter than the distance L2 from the nozzle opening 11 to the piston shaft section 5, but the present invention is not limited to this. When the length L1 of the extension hose section 12 is longer, it becomes possible to discharge the liquid to a remote position.

The pump dispenser A of the present invention can be widely used when changing the direction of liquid discharge in the pump dispenser A that discharges liquid downward.
For example, it can be used for household purposes such as hand washing soap in washrooms and dish detergent in the kitchen, as well as industrial purposes such as chemicals in manufacturing sites.
