[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trigger-actuating attachment for a trigger-type pump, a trigger-type ejection container to which the attachment is attached, and more specifically, a trigger-shaped member called a trigger. In a trigger type pump for ejecting liquid inside a liquid container such as various chemicals by operating with an attachment, an attachment to prevent the trigger from being activated and a trigger type to which such an attachment is attached. Regarding the ejection container.

[0002]

2. Description of the Related Art Generally, this type of trigger pump is
It is composed of a pump main body and a cap portion which is provided at a lower portion of the main body and can be screwed into the container.

A pump is attached by attaching such a cap portion to the mouth portion of a liquid container, and a piston is operated by pulling a trigger in an assembled state,
The structure is for ejecting the liquid inside the liquid container.

[0004]

Various liquids such as chemicals, detergents, cosmetics, etc. are stored inside the container in which such a trigger type pump is mounted, and the piston is operated by pulling the trigger. By doing so, the liquid inside the container is sucked and ejected in the form of a mist or foam, so the operation is similar to the operation of pulling the trigger of a handgun.

Therefore, as compared with other types of pump dispensers, this trigger type pump is often used in a mischief or for amusement especially for children and the like. Such mischief that activates the trigger by children, etc. or spray for play must be prevented at home, but it may occur at stores where products are displayed. However, it is necessary to prevent inadvertent discharge of the inner solution due to the operation of the trigger due to such mischief.

From the viewpoint of safety measures, the structure of the trigger is such that the liquid inside is not inadvertently sprayed or discharged.
A nozzle that can switch between a jettable open circuit and a jettable non-closed circuit is provided to switch between the open circuit position and the closed circuit position.However, when the nozzle position is in the closed circuit position direction, it is not provided. When the trigger is operated, due to the structure, the content liquid forcibly sucked up into the pump cylinder by the operation of the trigger is compressed and remains inside the trigger body without being discharged because the outlet is closed. become. In that case, when the nozzle position is rotated in the opening direction, the content liquid may be suddenly sprayed and discharged. If such an internal solution is a chemical or the like that may pose a danger to the body, the above-mentioned careless discharge, spray, etc. become a serious problem.

In particular, recently, non-gas type trigger pumps which do not use gas have been widely used due to the problem of air pollution. Among them, hypochlorous acid-based chemicals etc. are used for cleaning molds. The products used as
It is harmful though the content liquid is diluted, and in the case of such chemicals, especially in stores, etc., when the content liquid is compressed by intentionally actuating the trigger without opening the nozzle to the open position, etc., Even in a used empty container that has been consumed with liquid, the remaining content liquid may be suddenly sprayed by actuating the trigger, and a danger to the body cannot be avoided.

Therefore, in order to solve such a problem, various trigger type pumps having a safety device or the like for preventing the trigger operation have been developed.

However, in both cases, the structure of the safety device for preventing the operation is complicated, and the structure of the trigger type pump itself needs to be improved. However, there is a problem that it is difficult to provide it to

Therefore, attempts have been made to simplify the structure of the safety device, but in any case, the structure of a general-purpose trigger type pump without a safety device is modified to be a dedicated product. Without it, a trigger pump with a safety device cannot be provided for some applications such as cleaning agents.

The present invention has been made in order to solve such a problem, and it is not necessary to modify the trigger operating structure or mechanism of a general-purpose trigger type pump, and the general trigger type pump can be used as it is. Even if used, it is possible to suitably block the operation of the trigger, thereby eliminating the cost of modifying the trigger type pump, etc., and an attachment for blocking the operation of the trigger, and a jet equipped with such an attachment. An object is to provide a container.

[0012]

The feature of the attachment for preventing actuation is that the base 1 that can be mounted immediately below the mouth 20 of the container 19 in which the trigger type pump 25 is mounted and the rear surface side of the trigger 14 of the trigger type pump 25 are in contact with each other. In order to prevent the trigger 14 from operating, the attachment is configured with the stopper 4 that is continuously provided on the base 1.

The stopper 4 includes a support column 5 standing on the upper surface of the base 1 and a contact portion 6 for contacting the rear surface of the trigger 14.
And a erection portion 7 erected on the contact portion 6 and the pillar portion 5
Composed of and.

Further, a stopper 4 having such a configuration is formed into a flat surface substantially H-shaped.

On the front side of the stopper 4, preferably,
The protrusion 8 that is engaged in the groove 26 of the trigger 14 is formed.

The base 1 can be formed, for example, in a substantially ring shape.

In this case, the protrusion 3 can be formed on the inner peripheral surface of the base 1.

Further, the feature of the trigger type ejection container is that the base 1 which can be mounted directly below the mouth 20 of the container 19 in which the trigger type pump is mounted, and the trigger of the trigger type pump.
In order to prevent the operation of the trigger 14 by coming into contact with the rear surface side of the trigger 14, an attachment 9 for preventing the operation of the trigger, which comprises a stopper 4 connected to the base 1, the base 1 being the mouth of the container 19. It is to be mounted directly under the section 20.

In this case, the base 1 is formed in a substantially ring shape.
Thus , the flange portion 1b is formed on the upper surface of the base 1, the projection 3 is formed on the inner peripheral surface, and the projecting portion 27 and the small projecting portion 22 are formed immediately below the mouth portion 20 of the container 19. The protrusion 3 of the base 1 is engaged with the small protrusion 22 of the container 19, and the flange portion 1b of the base 1 is locked to the protrusion 27 of the container 19.

It is also possible to form a large protrusion 23 having a larger outer diameter than the inner peripheral surface of the base 1 under the small protrusion 22.

[0021]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

1 to 6, reference numeral 1 is a substantially ring-shaped base that can be externally fitted directly under the mouth of a container in which a trigger type pump is mounted, and is shown in FIGS. As shown in FIG. 6, it is formed in a substantially L-shaped cross section having an opening 2 on the upper surface.

A protrusion 3 is formed on the inner peripheral surface of the ring body 1 so as to engage with a small protrusion 22 of a mouth 20 of the container 19 described later.

Numeral 4 is a stopper which comes into contact with the rear surface side of the trigger 14 of the trigger type pump to prevent the operation of the trigger 14, and the stopper 4 stands upward along the outer edge of the upper surface of the base 1. The support 5 is provided, a contact portion 6 that contacts the rear surface side of the trigger 14, and a erection portion 7 erected on the contact portion 6 and the support portion 5.

The column portion of the column 5 is the trigger 14
Is arranged substantially straight so as to face the rear surface side, the contact portion 6 is arranged so as to be substantially parallel to the strut portion 5 and slightly inclined, and the erection portion 7 is further arranged to contact the strut portion 5 and the contact portion 6. It is arranged vertically so as to be orthogonal to the portion 6.

Therefore, as shown in FIG. 2, the stopper 4 is formed in a generally H-shaped plane.

Next, a description will be given of a case where the trigger operation preventing attachment 9 having the above-mentioned structure is attached to a container together with the trigger type pump.

First, the structure of this trigger type pump will be described. As shown in FIG. 7, the pump body 10 includes a pump body 11 and a cover body 12 fitted onto the pump body 11.
And a nozzle portion 13 provided on the front part of the pump body 11 for injecting liquid, and a trigger 14 that functions as a trigger when the liquid content is ejected.

Reference numeral 15 denotes a tube for sucking the liquid in the container, which is inserted from the pump body 11 to the cap portion 16 and the tip of which is bare under the cap portion 16.

Reference numeral 18 is a main body cylinder, and 17 is a piston that reciprocates in the cylinder 18.

The trigger 14 is connected to the front part of the piston 17, and the swinging motion of the trigger 14 is converted into the reciprocating motion of the piston 17.

Before attaching the trigger type pump having such a structure to the mouth portion 20 of the container 19, immediately below the mouth portion 20 of the container 19 to which the trigger type pump is attached, as shown in FIG. First, the operation preventing attachment 9 as described above is attached.

To explain this more specifically, the threaded portion 21
A projecting portion 27 is formed immediately below the mouth portion 20 of the container 19 in which is formed, and one projecting portion 22 is formed on the projecting portion 27.
Further, a single large protrusion 23 is formed on the lower part thereof.

The outer diameter of the large protrusion 23 is larger than the inner peripheral surface of the base 1.

Then, the base 1 of the attachment 9 is placed directly below the mouth 20 of the container 19 so that the flange 1b of the base 1 of the attachment 9 is locked to the projecting portion 27 of the container 19. Fit.

At this time, the protrusions 3 formed on the inner peripheral surface of the base 1 are engaged with the small protrusions 22 of the container 19.

As a result, the attachment 9 is mounted immediately below the mouth portion 20 of the container 19 so as to be rotatable below the mouth portion 20 of the container 19 without being detached downward. Of.

Further, since the outer diameter of the large protrusion 23 is formed to be larger than the inner peripheral surface of the base 1, it is also preferable to forcibly remove the attachment 9 forcibly. .

Next, after the attachment 9 is attached in this manner, the trigger type pump is attached.

That is, the cap portion of the trigger type pump
By screwing the 16 threaded portions 24 into the threaded portions 21 of the mouth 20 of the container 19, the trigger type pump can be attached.

In this way, as shown in FIG.
The trigger type pump 25 is attached to the mouth 20 of the valve 19. After that, by further rotating the base 1, the attachment 9 is placed so that the attachment 9 is located immediately below the trigger type pump 25. The mounting position of is to be adjusted.

Then, the contact portion 6 of the stopper 4 of the attachment 9 is brought into contact with the rear surface side of the trigger 14 of the trigger type pump, and further, as shown in FIG. The protrusion 8 is inserted into the groove 26 of the trigger 14 and engaged.

As a result, the attachment 9 is positioned at a specific position immediately below the trigger according to the direction of the trigger pump, and the attachment 9 prevents the trigger 14 from operating. still,
Even if the strut portion 5 of the attachment 9 is pushed and bent by the operation of the trigger 14, the strut portion 5 comes into contact with the outer side surface of the mounting cap portion 16 that is screwed into the container mouth portion, thereby preventing movement of the trigger.

That is, since the contact portion 6 of the stopper 4 comes into contact with the rear surface of the trigger 14 and the protrusion 8 of the contact portion 6 is inserted and locked in the groove portion 26 of the trigger 14,
Trigger 14 cannot be pulled backwards.

Therefore, since the forced movement of the content liquid and the compression of the content liquid due to the movement of the trigger do not occur, the liquid in the container does not spout carelessly.

Next, when it is desired to eject the liquid in the container, first, the nozzle is rotated to the open position and the base 1 is rotated to release the operation preventing state of the trigger 14 by the attachment 9. .

More specifically, by rotating the base 1, the protrusion 8 of the contact portion 6 of the stopper 4 is rotated.
11 is forcibly disengaged from the groove portion 26 of the trigger 14, and the engagement state between the contact portion 6 of the stopper 4 and the rear surface side of the trigger 14 is released.

Then, as shown in FIG. 12, the attachment 9 is rotated in one direction (arrow direction in FIG. 12).

As a result, the operation blocking state of the trigger 14 by the attachment 9 is released.

Therefore, the trigger 14 can be pulled backward.

When the trigger 14 is pulled backward, the piston 17 moves back in the cylinder 18, whereby the liquid in the container 19 is sucked by the tube 15, passes through the inside of the pump body 11, and is discharged from the nozzle portion 13. The liquid will be ejected.

As described above, in this embodiment, the contact portion 6 of the stopper 4 of the attachment 9 is brought into contact with the rear surface side of the trigger 14, and the protruding portion 8 of the contact portion 6 is inserted into the groove portion 26 of the trigger 14. The operation of the trigger 14 can be suitably blocked by simply engaging with each other, and by releasing the engagement state and rotating the attachment 9, it is possible to suitably prevent the trigger 14 from operating. It can be canceled.

In the above embodiment, the attachment 9
Since the protrusion 8 is formed on the contact portion 6 of the stopper 4 of
This is engaged with the groove portion 26 on the rear surface side of the trigger 14, and the preferable effect that the operation of the trigger 14 can be blocked more reliably was obtained. However, it is not necessary to form such a protruding portion 8 according to the present invention. Is not an indispensable condition.

The shape of the protruding portion is not particularly limited to a substantially semicircular shape, a square shape, or the like.

[0057]

Further, in the present embodiment, the support column 5 of the stopper 4 is formed in a plate shape, but the shape of the support column 5 is not limited to this embodiment.

However, as in the embodiment, the contact portion 6, the erection portion 7 and the support portion 5 of the stopper 4 are all formed in a plate shape, and the contact portion 6 and the support portion 5 are formed so as to face the trigger 14. Are arranged substantially in parallel with each other, and a plate-shaped erection portion 7 is arranged so as to be orthogonal to the contact portion 6 and the column portion 5.
When the erection portion 7 is erected on the contact portion 6 and the strut portion 5 in a vertical direction, the contact portion 6 and the strut portion 5 are reinforced by the erection portion 7, and the trigger 14 operates more reliably. It has the effect of being blocked by.

[0060]

In addition, in this embodiment, the base 1 is formed in a substantially ring shape, so that a preferable effect that the trigger 14 can be easily rotated for releasing the blocking is obtained. Forming in a substantially ring shape is not an essential condition for the present invention. For example, a part of the ring may be cut out to have a substantially C-shape. still,
It is also possible to apply so-called rib processing or grain processing to the outer peripheral surface of the base 1, and in this case, an anti-slip effect can be obtained when the base 1 is gripped, and rotation operation can be performed easily. The effect is that you can.

Further, the internal structure of the trigger type pump attached to the mouth of the container is not limited to the above embodiment, and the design can be changed arbitrarily.

[0063]

As described above, according to the present invention, the base which can be mounted directly below the mouth of the container in which the trigger type pump is mounted and the rear surface side of the trigger of the trigger type pump are brought into contact with each other. In order to prevent the operation of the trigger, the attachment is configured with the stopper that is connected to the base, so the operation of the trigger can be suitably blocked by the operation of bringing the stopper of the attachment into contact with the rear surface side of the trigger. Also, by rotating the attachment, it is possible to suitably release the operation blocking state of the trigger, and it is possible to realize the function of the safety device that blocks the operation of the trigger with a simple structure. .

As a result, unlike the conventional safety device for preventing trigger operation, it is not necessary to modify the structure of the trigger type pump itself, and the attachment as described above is attached directly below the mouth of the container. The trigger type pump with the above structure can be used as it is. As a result, there is an effect that the cost required for modifying the trigger type pump is unnecessary, and there is a great effect that the structure of the entire trigger type pump is not complicated.

Further, the stopper is provided with a support column which is erected on the upper surface of the base, a contact portion which comes into contact with the rear surface side of the trigger,
The contact portion and the support portion are provided on the support portion, and are formed so as to have a substantially H-shaped plane as a whole. Therefore , the support portion functions as a rib and is reinforced by the rib portion. The resulting structure has the effect of more reliably blocking the operation of the trigger.

Furthermore, when the protrusion is formed on the front side of the stopper so as to be inserted into the groove of the trigger, the stopper is more reliably prevented from being detached from the trigger, and the trigger is prevented from operating. The effect is that it can be performed more reliably.

Further, when the base is formed in a substantially ring shape, there is an effect that the turning operation for releasing the trigger operation inhibition can be easily performed.

Further, the trigger type ejection container of the present invention is
A base that can be mounted directly below the mouth of the container where the trigger pump is mounted, and a base that is connected to the rear surface of the trigger of the trigger pump to prevent the trigger from operating Since the base of the attachment for blocking the operation of the trigger consisting of the stopper is mounted just below the mouth of the container, the trigger itself is not modified at all as described above, and it serves as a safety device. Functions can be added.

In this case, the base is formed in a substantially ring shape, the flange is formed on the upper surface of the base, and the projection is formed on the inner peripheral surface, and the projection and the small projection are formed just below the mouth of the container. to form, since the flange portion of the engage and base the base of the projection to the small projections of the container engaged with the protruding portion of the container, there is an effect that is not the attachment is inadvertently disengaged .

In particular, when a large protrusion having an outer diameter larger than the inner diameter of the base is formed below the small protrusion, forcibly removing the attachment by mischief or the like is preferably prohibited. There is an effect. Further, even when spraying, there is an advantage that the presence of the large protrusions facilitates grasping.
