Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for defining a suction tube direction of a dispenser which defines the extending direction of the lower end of the suction tube inside the container after the dispenser is mounted on the container.

[0002]

2. Description of the Related Art For example, a dispenser that sucks up and pressurizes the liquid in a container by a reciprocating motion of a piston which is interlocked with the swinging of a trigger and the pressing of a nozzle head and discharges it from an outlet is called destruction of an ozone layer by CFC gas. Recently, due to environmental problems, it has attracted particular attention.

A so-called trigger type dispenser having a swingable trigger has, for example, a piston interlocked with the trigger, as disclosed in Japanese Patent Publication No. 57-032626. Then, the reciprocating motion of the piston in the cylinder communicating with the liquid flow path sucks and pressurizes the liquid in the container into the cylinder, and causes the liquid to flow out from the orifice (outlet) at the tip of the nozzle continuous with the flow path. Has been done.

In such a pump dispenser, usually, a suction tube communicating with the cylinder is provided so as to extend downward, and through the suction tube,
The liquid in the container can be sucked up into the cylinder.

[0005]

By the way, a trigger type dispenser used as an outflow means for cleaning detergent, floor liquid wax, etc. is usually held in a hand and used with its outlet (orifice) facing downward. . In other words, since the dispenser is often used by inclining forward (in the liquid outflow direction), when the remaining amount of the liquid is low, the liquid cannot be discharged unless the lower end of the suction tube is positioned in front of the container. There is a possibility that it will not be used up sufficiently and usage efficiency will be reduced.

Therefore, for example, there is known a structure in which the lower end of the suction tube is bent in advance in the liquid outflow direction, that is, in the front direction to prevent a decrease in liquid use efficiency. However, in such a configuration, since the suction tube is bent before the dispenser is attached to the container, the bent suction tube is an obstacle, and it is difficult to attach the dispenser from above. In particular, it is difficult to insert the dispenser into a container on a production line with an automatic machine, which may complicate the process of mounting the dispenser on the container and reduce workability.

Here, there is known a structure in which a guide having an inclined surface toward the outlet of the dispenser is fitted to the mouth of the container. In such a configuration, the extending direction of the lower end of the suction tube is automatically and forcibly defined in the liquid outflow direction due to the inclination along the inclined surface of the guide accompanying the insertion. Therefore, it suffices to insert the suction tube extending in the vertical direction into the mouth of the container from above, so that it can be sufficiently mounted by an automatic machine on the production line.

However, the setting of the guide to the mouth of the container can be performed only after the liquid is filled. Such a dispenser is usually sold as a finished product assembled by a manufacturer to a detergent company, etc.
After filling the container with liquid, it is installed on the same line, so to set the above guide to the mouth of the container,
It must be done on the detergent filling line by a detergent company.

That is, in the structure in which the guide is set at the mouth of the container, the guide cannot be set on the manufacturer side of the dispenser, so that the work is burdened on the detergent company side, and the filling is performed on the detergent company side. Inevitably, the workability of the mounting process is deteriorated.

An object of the present invention is to provide a suction tube direction defining structure of a dispenser which defines the extending direction of the lower end of the suction tube without providing a guide on the container.

[0011]

In order to achieve this object, according to the present invention, a direction defining guide having a guide piece slidable along the inside of the mouth of the container under abutment is provided. The suction tube at the lower end of the dispenser is fixed at a position aligned with the mouth of the container. The extension of the lower end of the suction tube can be regulated to the corresponding one direction by pushing out the direction regulating guide at the container mouth portion when the dispenser is attached.

[0012]

In this structure, since the suction tube is not bent before being attached to the container, the lower end of the suction tube can be easily inserted into the container. Since it is sufficient to fix the direction defining guide to the suction tube, the dispenser can be assembled on the manufacturer side.

[0013]

Embodiments of the present invention will now be described in detail with reference to the drawings.

As shown in FIG. 1, a suction tube direction defining structure 10 of a dispenser according to the present invention has a suction tube 14 extending below a dispenser 12.
It is configured such that the extending direction of can be defined after the dispenser is attached to the container 16.

As can be seen from FIG. 1, in the embodiment, for example, a so-called trigger type dispenser in which the liquid can flow out by swinging the trigger 18 is used.
This is illustrated as the dispenser 12. Such a dispenser (trigger type dispenser) 12 can be attached to the mouth 16a of the container 16 by, for example, screwing a rotatable bottle cap 20 provided at the lower end, and a suction tube inserted into the container. From 14, the liquid in the container is sucked up, pressurized, and discharged.

The dispenser 12 has a known structure disclosed in, for example, Japanese Examined Patent Publication No. 57-032626, and a piston slidable in the cylinder is connected to a trigger 18 so as to be interlockable. When the piston reciprocates in the cylinder in response to the swing of the trigger 18, the liquid in the container 16 becomes
It is sucked up from the suction tube 14 through the primary valve into the cylinder and is pressurized. Then, the pressurized liquid flows out of the cylinder through the secondary valve, is vortexed by the spinner at the tip of the outflow passage, and flows out as a spray flow from the dispenser front end 12a having an orifice serving as a liquid outlet in the center. Is sprayed).

Here, as shown in FIG. 1, in the present invention, at the position where the direction defining guide 22 having the guide piece 22a capable of contacting the mouth 16a of the container is aligned with the mouth of the container,
It is fixed to the suction tube 14. As can be seen from FIG. 2 in addition to FIG. 1, the direction defining guide 22 is formed to have a base portion 22b integral with the guide piece 22a, and can be fixed by fitting the base portion to the suction tube 14. There is. The base 22b of the direction defining guide is, for example,
It is formed in a pipe shape that allows the suction tube 14 to be fitted in the axial direction.

The guide piece 22a of the direction defining guide is formed in a shape slidable along the inner surface of the mouth of the container under the contact with the mouth 16a of the container, for example, in the shape of an inclined surface as shown in the drawing. Is positioned in the direction opposite to the spraying (outflow) direction of the liquid, and the direction defining guide 22 is fixed to the suction tube 14. Then, as shown in FIG. 3, the guide piece 22a of the direction defining guide is, for example,
At the initial position, the amount of protrusion is such that it can contact the inner surface of the bottle cap 20.

The dispenser 12 as described above is normally delivered to the detergent supplier from the manufacturer in a state where it is fully assembled including the direction defining guide 22, and is used in the production line of the detergent operator, that is, the liquid filling line or the like. After being filled with the liquid, it is mounted by an automatic machine or the like.

In the liquid filling line, the dispenser 12 is arranged in line with the mouth 16a of the container for which the liquid filling process has been completed, and is inserted from the lower end 14a of the suction tube 14 by lowering the dispenser with respect to the container 16. (See FIG. 3).

Here, before the dispenser 12 is attached to the container 16, the suction tube 14 is maintained in a vertically extended state because it is not regulated in any direction. That is, since the suction tube 14 is extended along the movement direction of the dispenser in the step of mounting the dispenser 12 on the container 16, the suction tube is easily inserted into the container and the mounting work is simplified. .

From the state of FIG. 4 in which the guide piece 22a of the direction regulation guide is brought into contact with the mouth 16a of the container, the dispenser 12
When the bottle cap 20 is further screwed to the mouth of the container, the bottle is pushed down under the slide of the guide piece along the inner surface of the mouth of the container, and the suction tube 14 serves as a liquid outlet. It is forcibly bent in the direction of the front end 12a of the dispenser. Then, as shown in FIG. 1, the extension direction of the lower end 14a of the suction tube is the outflow direction of the liquid under the contact between the guide piece 22a of the direction defining guide and the inner surface of the container mouth 16a. It is defined and held in the direction of the front end 12a.

According to this construction, since the extension direction of the lower end 14a of the suction tube is regulated to the outflow direction of the liquid from the dispenser 12, even if the container is tilted in the outflow direction of the liquid during use, the lower end of the suction tube is Is located in the first half of the bottom portion where the liquid with a small remaining amount is accumulated. Therefore,
Even when the container 16 is tilted and used, the liquid can surely flow out, and the liquid use efficiency of the dispenser 12 is improved.

Since the direction defining guide 22 need only be assembled when the dispenser 12 is assembled,
No additional work is required on the detergent side after filling the liquid. That is, the work of mounting the dispenser 12 on the container 16 can be performed in the same process as the conventional process, and therefore the workability on the side of the detergent company is not deteriorated.

Further, since the lower end 14a of the suction tube is automatically regulated in the liquid outflow direction when the dispenser 12 is attached to the container 16, the workability at the time of attachment is not complicated.

Here, in the embodiment, the direction defining guide 22 is exemplified as the structure having the pipe-shaped base portion 22b into which the suction tube 14 can be fitted, but if it can be fixed to the suction tube 14, Therefore, the shape of the base is not limited to the pipe shape, and the base may be formed in a substantially C-shaped cross section having an opening 24 along the axis as shown in FIG. 5, for example.

In such a structure, the suction tube
The direction defining guide 22 can be fixed to the suction tube by the work of fitting the base portion 22b in the direction orthogonal to the axis of 14. That is, since the direction defining guide 22 can be attached to the suction tube 14 after the dispenser 12 is assembled, even in a configuration in which the direction defining guide 22 cannot be fixed before fixing the suction tube to the dispenser body. The suction tube direction defining structure 10 of the invention can be applied. That is, since the direction defining guide 22 can be retrofitted, the range of dispensers to which the suction tube direction defining structure 10 of the present invention can be applied is expanded.

In the embodiment, the direction defining guide 22 is also used.
Is embodied as a configuration having a single plate-shaped guide piece 22a, but the number of guide pieces is not limited to this, and, for example, as shown in FIG. The direction defining guide may be formed in a shape having the guide piece of. According to the direction defining guide 22 having such a plurality of guide pieces 22a, the angle of the direction defining guide is stabilized with respect to the container mouth by the contact of the plurality of guide pieces with the inner surface of the container mouth 16a. Therefore, the displacement of the suction tube lower end 14a with respect to the container 16 in the extending direction is prevented.

Although the direction defining guide 22 is shown in FIG. 6 (A) as a structure having three guide pieces 22a, the number of guide pieces is not limited to this, and for example, two pieces may be used. It goes without saying that four sheets or the like may be used.

Further, although the plate-shaped guide piece 22a is illustrated, it is sufficient if the shape is such that it can be brought into contact with the mouth 16a of the container and can be slid along the inner surface of the mouth. For example, as shown in FIG. The guide piece of the direction defining guide may be formed in a substantially spherical shape as shown in FIG.

By the way, in the above embodiment, the direction defining guide piece 22 is embodied as a structure to be fixed to the suction tube 14, but it is not limited to this.
For example, as shown in FIG. 7, the dispenser may be attached to the packing 26 by press fitting.

The packing 26 is formed so as to be elastically deformable under the pressure of the pressing piece 28 that moves in association with the swing of the trigger 18, and the air from the outside circulates due to this elastic deformation, whereby the packing 16 of the container 16 is Configured to prevent negative pressure inside,
It is arranged.

As can be seen from FIG. 8 in addition to FIG. 7,
Suction tube direction regulation structure of this dispenser
In 110, the base portion 122b of the direction defining guide 122 is formed as, for example, a press-fitting piece that is fitted into the packing 26 under press-fitting, and is connected to the guide piece 122a via an elastically deformable connecting piece 122c. They are connected together. And
A pair of sandwiching pieces 122d that sandwiches the suction tube 14 and prevents the guide piece from being displaced with respect to the suction tube,
It integrally extends in the opposite direction of the guide piece 122a.

The direction defining guide 122 is an elastic deformation of the connecting piece 122c, that is, a guide piece for the press-fitting piece (base) 122b.
The elastic material 122a is formed so that it can be elastically deformed and can be press-fitted with elasticity.

Also in the direction defining guide 122, the guide piece 122a is the same as in the above-mentioned embodiment.
It is formed in such a shape that it can slide along the inner surface of the mouth with a protrusion amount capable of abutting on 16a.

Even in such a configuration, the suction tube 14 is pushed out together with the direction defining guide 122 under the contact of the guide piece 112a with the container mouth 16a when the dispenser 12 is attached to the container 16. Similarly to the above embodiment, the direction of the lower end of the suction tube can be reliably defined.

Since the direction-defining guide 122 is attached to the packing 26 while the press-fitting piece 122b is press-fitted, the deviation of the direction-defining guide from the dispenser 12 can be prevented. Therefore, in this configuration, the suction tube
The vertical position and the angular deviation of the guide piece 122a with respect to 14 can be sufficiently prevented, and the stability of the position of the guide piece is improved.

In such a direction defining guide 122, a notch 30 is provided in the press-fitting piece 122b as shown in FIG. By providing the notch 30, an elastic deformation space of the packing 26 can be secured, so that air can be circulated in conjunction with the swing of the trigger 18, and the function of using the packing for mounting the direction regulation guide 122 can be obtained. The decline can be stopped.

Here, in such a configuration, for example, as shown in FIG. 9, a flange is provided at the lower end of the press-fitting piece 122b.
122e should be installed. If the flange 122e is provided in this way, the flange can be used as a hooking piece when press-fitting, so that the press-fitting work of the press-fitting piece 122b into the packing 26, that is, the work of attaching the direction defining guide 122 to the dispenser 12 is easy. It becomes possible to automate and eventually automate.

Further, it is preferable to form the outer surfaces of the pair of holding pieces 122d as parallel flat surfaces. In this way, if the outer surfaces of the pair of sandwiching pieces 122d are made flat, it is possible to easily align the direction defining guides 122 in one direction, which is effectively used for alignment during automatic assembly. it can.

Further, for example, as shown in FIG. 10, a projection 32 may be provided on the upper surface of the press-fitting piece 122b so that it can be fitted into a corresponding recess (not shown) on the dispenser side. According to such a configuration, the rotation of the direction defining guide 122 with respect to the dispenser 12 is prevented by the fitting between the protrusion 32 and the recess, so that the angle stability of the guide piece 122a is further improved.

Here, the protrusion 32 is provided on the press-fitting piece 122b of the direction defining guide to prevent the rotation by fitting into the concave portion of the dispenser side. On the contrary, the protrusion is provided on the dispenser side in the direction. The press-fitting pieces of the regulation guide may each be provided with a recess.

Further, as shown in FIG. 11, a direction defining guide 122 may be formed integrally with the packing 26. In this case, the base of the direction defining guide 122 is formed as the packing 26.

Even in such a configuration, the mouth 16 of the container
Under the extrusion of the guide piece 122a by a, the direction regulation of the lower end of the suction tube 14 can be accurately obtained. Further, in this configuration, the packing 26 serves as the direction defining guide 122.
Since it is integrally formed as a part of the structure, the number of parts can be reduced and the configuration can be simplified and the workability can be improved.

It should be noted that the guide pieces 22a and 122a are provided at the mouth portion 16 of the container.
The shape is not limited to the shape shown in the figure, as long as the shape can be in contact with a and can slide along the inner surface of the mouth.

Further, in the embodiment, the trigger type dispenser having the swingable trigger 18 is exemplified as the dispenser 12, but the present invention is not limited to this.
The present invention can be applied to other dispensers, for example, a push type dispenser in which liquid is discharged by pushing the nozzle head.

Further, in the embodiment, the guide pieces 22a, 12a
The direction defining guides 22 and 122 are fixed by arranging 2a in the direction opposite to the liquid outflow direction.For example, in a dispenser of the type in which the liquid outflow direction is used as the upward direction, the guide piece causes the liquid outflow. It is good to arrange in the direction and to fix a direction guide. In this configuration, since the lower end of the suction tube is located at the rear end of the bottom portion that serves as a liquid reservoir when the dispenser is used upward, it is possible to prevent the use efficiency of the liquid from being lowered, as in the above embodiment.

The above-mentioned embodiments are for explaining the present invention, and do not limit the present invention in any way.
It goes without saying that the present invention includes all those which are modified or modified within the technical scope of the present invention.
