Description

  The present invention relates to a volatile liquid spraying device that sprays a volatile liquid into the atmosphere.

  Various devices for spraying volatile liquids such as fragrances and deodorants into the atmosphere have been provided, but the basic configuration is to suck up the volatile liquid filled in the container with a suction core. The sucked volatile liquid is volatilized outside the container and dispersed in the atmosphere (see Patent Document 1).

Japanese Utility Model Publication No. 06-38996

By the way, volatile liquids will volatilize if left in the atmosphere, so in the stage before use, the mouth of the container containing the volatile liquid is covered with a cap or seal. The configuration to be kept is common.
Therefore, when using, the effort which removes a cap, a seal | sticker, etc. from a mouth part was required. In particular, in many cases, a cover body in which a spray hole for spraying a volatile component of a volatile liquid is detachably fixed to the upper portion of the container. In this case, the procedure of attaching the cover body after removing the cap, the seal, and the like is a procedure that is extra time consuming.

  The present invention has been made in consideration of such circumstances, and its purpose is to provide a volatile liquid spraying device that can quickly set a volatile liquid to a volatilizable state without taking time and effort during use. Is to provide.

A movable body provided with a blade portion at a tip portion located on the bottom side of the container, a columnar suction core that is held by the movable body and volatilizes after the volatile liquid is sucked out of the container, and the container A peripheral cylindrical portion mounted on the outer peripheral surface and capable of descending in the container axial direction; and a top wall portion continuously provided on the peripheral wall portion; The cover body moves downward as the cover body descends, and the blade portion causes the bottom of the insertion tube Without even communicates the inside and the insertion tube by partially open vessel, said volatile liquid, characterized in that to reach the wicking core.

  In the volatile liquid spraying apparatus according to the present invention, the bottom of the insertion tube attached to the mouth is closed before use. Therefore, the volatile liquid filled in the container does not touch the atmosphere outside the container. Therefore, the volatile liquid does not volatilize before use.

  On the other hand, when used, the cover body is lowered in the container axial direction. Then, a downward force is applied to the base end portion of the movable body in which the top wall portion of the cover body protrudes out of the container. Thereby, both the movable body and the suction core held by the movable body move downward in the insertion cylinder. As a result of the downward movement, the blade provided at the distal end of the movable body presses against the bottom of the insertion tube, and at least a part of the bottom is opened. Thereby, the inside of an insertion cylinder and the inside of a container can be connected, and the volatile liquid with which the inside of a container is filled can reach a suction core. Then, the volatile liquid is sucked upward by the suction core and then volatilized by touching the atmosphere outside the container. Then, the volatilized component is dispersed around the device.

  Thus, by lowering the cover body in the container axial direction, the volatile liquid can be volatilized and dispersed in the atmosphere.

Furthermore, an impregnation plate impregnated with the volatile liquid is fixed.

  In the volatile liquid spraying apparatus according to the present invention, the impregnated plate can be impregnated with the volatile liquid sucked up by the suction core outside the container. At this time, the impregnated volatile liquid spreads over the entire impregnating plate, so that it becomes easier to touch the atmosphere. That is, since the surface area of the impregnation plate is large, the volatile liquid can be exposed to the atmosphere over a wider range. Therefore, the volatile liquid can be volatilized more efficiently, and the spraying performance can be improved.

Hereinafter, an embodiment of a volatile liquid spraying apparatus according to the present invention will be described with reference to FIGS. 1 to 6.
As shown in FIGS. 1 and 2, the volatile liquid spraying device 1 of the present embodiment is a device that sprays the volatile liquid W into the atmosphere, and includes a container 2, an insertion cylinder 3, a movable body 4, and the like. A suction core 5 and an outer cover (cover body) 6 are provided.
In the present embodiment, a case where the movable body 4 is lowered by rotating and lowering the exterior cover 6 will be described as an example.

  FIG. 1 is an external perspective view of the volatile liquid spraying device 1. FIG. 2 is a longitudinal sectional view of the volatile liquid spraying apparatus 1. In addition, each central axis of each component is located on a common axis. In the present embodiment, this common axis is referred to as a container axis O, a direction orthogonal to the container axis O is a radial direction, and a direction around the container axis O is a circumferential direction. Examples of the volatile liquid W include fragrances, deodorants, and insecticides.

The container 2 is formed in a bottomed cylindrical shape having a bottom portion 10 and a mouth portion 11, and a volatile liquid W is filled therein. On the outer peripheral surface of the mouth portion 11, a male screw portion 11a to which the female screw portion 20a of the insertion tube 3 is screwed is formed. Moreover, the container 2 of this embodiment is formed so that an outer peripheral surface may become a step, the bottom part 10 side becomes the large diameter part 12, and the opening part 11 side becomes the small diameter part 13. FIG. The large-diameter portion 12 and the small-diameter portion 13 are connected via a step portion 14.
Further, on the outer peripheral surface of the small diameter portion 13, a male screw portion 13 a that is screwed into a female screw portion 40 a formed on the peripheral wall portion 40 of the exterior cover 6 is formed.

The insertion cylinder 3 is a member formed in a bottomed cylindrical shape, and is inserted into the mouth 11 of the container 2 and is inserted into the container 2 from the mouth 11 toward the bottom 10 of the container 2. Yes.
More specifically, the insertion tube 3 surrounds the periphery of the mouth portion 11 and has an outer tube 20 in which a female screw portion 20a screwed to the male screw portion 11a is formed on the inner peripheral surface, and a radially inner side of the outer tube 20 And an inner cylinder 21 whose lower end is shielded by the bottom 22, and a continuous portion 23 that connects the upper end of the outer cylinder 20 and the upper end of the inner cylinder 21.
The insertion tube 3 can be attached to the mouth portion 11 of the container 2 by screwing the female thread portion 20 a of the outer tube 20 into a male screw portion 11 a formed in the mouth portion 11.

The inner cylinder 21 is a cylindrical member that is inserted into the container 2 from the mouth 11 when the insertion cylinder 3 is mounted, and is formed to extend from the mouth 11 toward the bottom 10 of the container 2. The lower end portion is designed to be located near the bottom portion 10. And the bottom part 22 mentioned above is provided in a row by this lower end part.
Thereby, unless the bottom part 22 opens, the volatile liquid W does not penetrate | invade in the inner cylinder 21 inserted in the inside of the container 2. FIG.
Here, an annular groove 24 formed in an annular shape around the container axis O is formed in the bottom portion 22 of the present embodiment. Since the annular groove 24 functions as a weakened portion having lower rigidity than other portions, the bottom portion 22 is designed so that the bottom portion 22 can be easily opened with the annular groove 24 as a base point.

By the way, the upper end portion of the inner cylinder 21 is provided with an abutting cylinder 21 a that has a larger diameter than the lower end side and abuts against the inner peripheral surface of the mouth portion 11. Thereby, shakiness of the insertion cylinder 3 can be suppressed, and the insertion cylinder 3 can be stabilized. Moreover, even if the container 2 is tilted excessively, the volatile liquid W does not leak from between the contact cylinder 21a and the mouth portion 11.
Further, as shown in FIG. 3, four guide ribs 25 for guiding the downward movement of the movable body 4 described later are formed around the container axis O every 90 degrees on the inner peripheral surface of the contact cylinder 21a. Yes. 3 is a cross-sectional view taken along line AA shown in FIG. However, the number of guide ribs 25 is not limited to this number, and may be designed freely. Further, the positions of the guide ribs 25 need not be uniform in the circumferential direction, and may be formed unevenly.

As shown in FIG. 2, the movable body 4 is housed in the insertion tube 3 so that the movable body 4 can move downward and the base end portion protrudes out of the container 2. This is a member provided with a blade portion 30a.
More specifically, as shown in FIGS. 2 and 4, the movable body 4 of the present embodiment has a rod portion 30 that is formed in a cylindrical shape and elongated along the container axis O, and the rod portion. And a plate 31 attached to the base end portion of 30.
FIG. 4 is a perspective view of the movable body 4 holding the suction core 5. Further, in order to make the drawing easier to see, a state where the light passes through the plate 31 is shown.

  The rod portion 30 is formed in such a size that a slight gap is secured between the rod portion 30 and the inner tube 21 when the rod portion 30 is accommodated in the insertion tube 3. The tip of the rod portion 30 is formed so as to protrude downward at only one location in the circumferential direction. The protruding portion is the above-described blade portion 30a. By pressing the blade portion 30 a against the bottom portion 22 of the insertion cylinder 3, at least a part of the bottom portion 22 can be opened.

Further, the base end portion of the rod portion 30 protrudes outside the container 2 and the plate 31 is integrally attached to the end portion. The plate 31 is a plate extending along a plane perpendicular to the container axis O, and is formed in a circular shape in plan view. However, it may be formed in an elliptical shape in a plan view, a rectangular shape, or a polygonal shape. A rib 31 a protruding in a triangular shape is formed at the approximate center of the lower surface of the plate 31.
Further, a notch portion 32 cut out along the circumferential direction is formed at the proximal end portion of the rod portion 30 so as to face each other with the container axis O interposed therebetween.

The movable body 4 configured in this manner holds a suction core 5. The suction core 5 is formed in a long cylindrical shape having a length similar to that of the rod portion 30 with a nonwoven fabric or the like, and plays a role of volatilizing after sucking the volatile liquid W out of the container 2. . The suction core 5 is adjusted in length so that the lower end portion does not protrude from the rod 30.
Moreover, in this embodiment, the suction core 5 is inserted and inserted from the tip of the rod portion 30 of the movable body 4. At this time, the proximal end portion of the suction core 5 is in contact with the plate 31. Therefore, a part of the suction core 5 is exposed through the notch 32. In addition, the rib 31 a formed on the plate 31 causes the proximal end portion of the suction core 5 to slightly bulge outward in the radial direction, and a force is applied so that the force protrudes from the notch portion 32 to the outside of the rod portion 30. Yes.

Further, an impregnation plate 35 that is in contact with the suction core 5 and impregnated with the volatile liquid W sucked up by the suction core 5 is fixed to the base end portion of the movable body 4.
The impregnated plate 35 is an impregnated body formed in the shape of a circle in plan view with the same material as the suction core 5, and the gap between the end surface 32 a of the arc-shaped rod portion 30 that appears by the notch portion 32 and the plate 31. It is fixed by being sandwiched between. Specifically, as shown in FIG. 5, the movable body 4 holding the suction core 5 is inserted into the slit 35 a formed at the center of the impregnation plate 35 so that the base end is fixed. It has become. 5 is a cross-sectional view taken along line BB shown in FIG.
In particular, as described above, a part of the suction core 5 is exposed through the notch 32, so that the exposed portion and the impregnation plate 35 come into contact with each other. In addition, since force is applied to the suction core 5 so as to protrude from the notch portion 32 to the outside of the rod portion 30 by the rib 31a, the rib 31a comes into close contact with the impregnation plate 35.

As shown in FIGS. 1 and 2, the exterior cover 6 is a member formed in a cylindrical shape with a peripheral wall portion 40 and a top wall portion 41, and covers the movable body 4 and the container 2 from above.
If it demonstrates in detail, the surrounding wall part 40 will be formed so that the circumference | surroundings of the small diameter part 13 of the container 2 may be surrounded, and the internal thread part 40a threadedly engaged with the external thread part 13a is formed in the internal peripheral surface. Therefore, the peripheral wall 40 can be rotated and lowered around the container axis O. That is, the outer cover 6 itself can be rotated and lowered around the container axis O.

  The top wall portion 41 is connected to the upper end portion of the peripheral wall portion 40, and is formed with a spray hole 42 that discharges and spreads the component in which the volatile liquid W has volatilized to the outside of the exterior cover 6. The spray hole 42 of the present embodiment is formed at a position slightly deviated radially outward from the center of the top wall 41 and has a circular shape in plan view. Further, the spray hole 42 is shielded by the impregnation plate 35 extending to the vicinity of the inner peripheral surface of the peripheral wall portion 40.

  Further, the lower surface of the top wall portion 41 is in contact with the proximal end portion of the movable body 4, specifically, the plate 31. Therefore, the movable body 4 can be pushed down and moved downward by rotating and lowering the exterior cover 6. Further, by moving the movable body 4 downward, the blade portion 30a is pressed against the bottom portion 22 of the insertion tube 3 to open at least a part of the bottom portion 22 so that the insertion tube 3 and the container 2 communicate with each other. The volatile liquid W can reach the suction core 5. This point will be described later in detail.

By the way, in this embodiment, the strip | belt-shaped regulation member 45 which can be removed on the outer peripheral surface of the container 2 is formed over the perimeter. The regulating member 45 has a lower end portion placed on the stepped portion 14 of the container 2, and an upper end portion formed on a lower end portion of the peripheral wall portion 40 of the exterior cover 6 by a weakened portion (a thin portion or a plurality of connecting pieces). Easy to break and connected. Further, a knob 45 a is provided at the end of the regulating member 45 when the regulating member 45 is removed. Then, by removing the regulating member 45 using the knob 45a, a gap can be opened between the lower end portion of the peripheral wall portion 40 of the exterior cover 6 and the stepped portion 14 of the container 2, so that the exterior cover 6 Can be rotated and lowered.
That is, it is designed so that the outer cover 6 cannot be rotated and lowered unless the regulating member 45 is removed. Therefore, the restricting member 45 restricts the rotation and lowering of the exterior cover 6.
The regulating member 45 may not be connected to the exterior cover 6 via the weakened portion. In this case, the upper end portion of the regulating member 45 may be in contact with or close to the lower end portion of the peripheral wall portion 40 of the exterior cover 6.

Further, as shown in FIGS. 2 and 4, the movable body 4 according to the present embodiment has a flow groove (flow) that circulates the volatile liquid W from the tip of the blade portion 30 a toward the suction core 5 by a capillary phenomenon or the like. Road) 46 is formed.
The flow groove 46 is formed on the inner peripheral surface of the rod portion 30 of the movable body 4. Specifically, it is formed so as to extend from the front end portion of the blade portion 30a to reach the suction core 5 directly above, and then extends about ¼ turn along the circumferential direction. Thereby, when opening is opened in the bottom part 22 of the insertion cylinder 3 by the blade part 30a, even if the opening is slight, the volatile liquid W is made to reach the suction core 5 through the flow groove 46. Can be done.
When the flow groove 46 is formed, the flow groove 46 is formed from the tip of the blade portion 30 a toward the top until reaching the suction core 5, and is then formed on the inner peripheral surface of the rod portion 30 so as to surround the suction core 5 once. It may be formed in a ring shape.

Next, the case where the volatile liquid W is spread in the atmosphere using the volatile liquid spraying apparatus 1 configured as described above will be described.
First, the state before use will be briefly described.
In the stage before use, as shown in FIG. 2, the mouth 11 of the container 2 is closed by the bottomed cylindrical insertion cylinder 3, and the bottom 22 of the insertion cylinder 3 is closed. Therefore, the volatile liquid W filled in the container 2 does not touch the atmosphere outside the container 2. Accordingly, the volatile liquid W is prevented from volatilizing at the stage before use.
Further, since the rotation lowering of the outer cover 6 is restricted by the regulating member 45, the outer cover 6 is prevented from rotating and lowering unexpectedly or accidentally.

Then, the case where it uses is demonstrated.
First, the regulating member 45 is removed using the knob 45a. At this time, the upper end portion of the restricting member 45 is simply connected to the peripheral wall portion 40 so as to be easily broken, so that it can be easily removed and can immediately move to the subsequent rotating and lowering operation of the exterior cover 6. it can.

  After removing the regulating member 45, as shown in FIG. 6, the exterior cover 6 is rotated around the container axis O and is rotated and lowered to the container 2 side. Then, along with this, the top wall portion 41 of the exterior cover 6 applies a downward force to the proximal end portion of the movable body 4 protruding out of the container 2. Thereby, both the movable body 4 and the suction core 5 held by the movable body 4 move downward in the insertion tube 3. As a result of the downward movement, the blade portion 30 a provided at the distal end portion of the movable body 4 presses against the bottom portion 22 of the insertion cylinder 3 and opens at least a part of the bottom portion 22. Thereby, the inside of the insertion cylinder 3 and the inside of the container 2 can be communicated, and the volatile liquid W filled in the container 2 can reach the suction core 5.

  Then, the volatile liquid W is sucked upward by the suction core 5 and then volatilized by touching the atmosphere outside the container 2. The volatilized component is sprayed around the volatile liquid spraying device 1 through the spraying hole 42 of the outer cover 6.

  Thus, by rotating and lowering the exterior cover 6 around the container axis O, the volatile liquid W can be volatilized and dispersed in the atmosphere. In particular, unlike the conventional case where it takes time and effort to remove the cap, the seal, etc. from the mouth portion 11, the volatile liquid W can be removed without taking time and effort by simply rotating and rotating the exterior cover 6. It can be quickly set to a volatizable state. Therefore, it is very easy to use and excellent in convenience.

Moreover, according to the volatile liquid spraying apparatus 1 of this embodiment, the following effects can also be achieved.
First, since the annular groove 24 is formed in the bottom part 22 of the insertion cylinder 3, when the blade part 30a is pressed against the bottom part 22, it is easy to open an opening in the bottom part 22 using the annular groove 24 as a base point. Therefore, the volatile liquid W can be set to a state where it can be volatilized more quickly.
Moreover, since the downward movement of the movable body 4 is guided by the guide ribs 25, rattling or the like hardly occurs during the downward movement. Therefore, the blade portion 30a can be reliably pressed against the bottom portion 22 of the insertion cylinder 3, and the opening can be easily opened in the bottom portion 22 in this respect as well.

  Further, when the opening is opened in the bottom portion 22 of the insertion tube 3, even if the opening is slight, the volatile liquid W is sucked up by the capillary phenomenon or the like through the flow groove 46 and reaches the suction core 5. Can be made. Therefore, the reliability of spraying can be improved.

Further, since the impregnation plate 35 is fixed to the base end portion of the movable body 4, the impregnation plate 35 can be impregnated with the volatile liquid W sucked up by the suction core 5 outside the container 2. In particular, the volatile liquid W impregnated in the impregnating plate 35 spreads over the entire impregnating plate 35, so that it becomes easier to touch the atmosphere. That is, since the surface area of the impregnation plate 35 is large, the volatile liquid W can be exposed to the atmosphere over a wider range. Therefore, the volatile liquid W can be efficiently volatilized and the spraying performance can be improved.
Moreover, since the impregnation plate 35 is disposed so as to shield the spray hole 42, the volatile component can be immediately sprayed through the spray hole 42. Accordingly, the spraying performance can be further enhanced.

  Further, since the outer peripheral surface of the abutting tube 21a of the insertion tube 3 is in contact with the inner peripheral surface of the mouth portion 11, the backlash of the insertion tube 3 attached to the mouth portion 11 is suppressed, and the insertion tube 3 is stabilized. Can be achieved. Therefore, the movable body 4 can be smoothly moved downward within the insertion cylinder 3.

  During use, the air that has entered the exterior cover 6 from the spray hole 42 is designed to reach the container 2 through the gap between the insertion tube 3 and the movable body 4. Thereby, air replacement can be suitably performed by the amount of the volatile liquid W sucked up. Therefore, it is possible to prevent the inside of the container 2 from becoming a negative pressure, and it is possible to favorably suck up the volatile liquid W.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, in the above embodiment, the rod portion 30 is formed in a cylindrical shape, but is not limited to this case, and may be designed freely. Any shape that can hold at least the suction core 5 and can move downward while being accommodated in the insertion tube 3 may be used.
In addition, although the circular spray hole 42 in plan view is formed in the top wall portion 41 of the exterior cover 6, it is not limited to a circular shape, and may be freely designed such as an elliptical shape, a polygonal shape, a corrugated shape, a geometric shape, or the like. Absent. Further, the number of spray holes 42 may be freely designed.

In the above embodiment, the exterior cover 6 and the movable body 4 are separate members, and the push-down plate 31 is in contact with the lower surface of the top wall portion 41 of the exterior cover 6. The plate 31 may be connected and the exterior cover 6 and the movable body 4 may be integrally formed.
In this case, since the movable body 4 does not fall by itself when the exterior cover 6 does not rotate, the blade portion 30a hits the bottom 22 of the insertion tube 3 before use, or the exterior cover 6 rotates and descends. It is possible to prevent the movable body 4 from further descending toward the bottom 10 of the container 2 later. In particular, in the above embodiment, when the outer cover 6 is rotated and lowered, the lower end portion of the peripheral wall portion 40 hits the stepped portion 14 of the container 2, so that the lowering amount of the outer cover 6 can be limited. Therefore, it is possible to simultaneously prevent the movable body 4 from being lowered excessively.

When the exterior cover 6 and the movable body 4 are separate members as in the above embodiment, a slight gap is opened between the rod portion 30 of the movable body 4 and the inner cylinder 21 of the insertion cylinder 3. Instead, the rod portion 30 may be slidably contacted with the inner cylinder 21 in the container axis O direction.
In this case, it is possible to prevent the movable body 4 from descending when the exterior cover 6 is not rotated by using the frictional force generated by the sliding contact. Accordingly, similarly, the blade portion 30a hits the bottom portion 22 of the insertion tube 3 before use, or the movable body 4 further descends toward the bottom portion 10 of the container 2 after the outer cover 6 is rotated and lowered. Can be prevented.

  However, when the rod portion 30 is slidably contacted with the inner cylinder 21, the air at the time of air replacement becomes difficult to circulate. Therefore, the concave groove for circulation is used as the inner peripheral surface of the inner cylinder 21 or the rod. What is necessary is just to form along the container axis | shaft O in either of the outer peripheral surfaces of the part 30. FIG.

Furthermore, when the exterior cover 6 and the movable body 4 are separate members, the movable body 4 even if there is a slight gap between the rod portion 30 of the movable body 4 and the inner cylinder 21 of the insertion cylinder 3. You may provide the member which controls that 4 falls by itself.
For example, a protrusion that protrudes radially outward is formed on the outer peripheral surface of the rod portion 30, and a locking protrusion that can be overcome when the movable body 4 descends on the inner peripheral surface of the inner cylinder 21. Form. By doing so, the movable body 4 can be prevented from lowering when the exterior cover 6 is not rotated, and the movable body 4 can be lowered when the exterior cover 6 is rotated. And when comprised in this way, since air can be distribute | circulated using between the rod part 30 and the inner cylinder 21, air replacement can be performed reliably.

In the above embodiment, when the outer cover 6 is rotated and lowered, the movable body 4 is simply moved downward without rotating. However, the outer cover 6 is moved downward while rotating as the outer cover 6 rotates. You may comprise as follows.
In this case, for example, protrusions and recesses that engage with each other are formed on the lower surface of the top wall portion 41 of the exterior cover 6 and the upper surface of the plate 31, respectively, and the rotational force of the exterior cover 6 is controlled by the movable body 4. It is sufficient to use a configuration that tells In particular, by moving the movable body 4 downward while rotating, the blade portion 30a can be pressed against the bottom portion 22 of the insertion tube 3 while rotating, and the opening can be opened in the bottom portion 22 more efficiently. Therefore, the volatile liquid W can be set to a state where it can be volatilized more quickly.

In the above embodiment, the case where the outer cover 6 is rotated and lowered has been described as an example. However, the outer cover 6 may be attached to the container 2 so as to be able to be lowered in the container axis O direction. Even in this case, the same effects can be achieved.
However, it is possible to prevent the movable body 4 from suddenly moving downward by configuring the exterior cover 6 to rotate downward as in the above embodiment. Therefore, the opening can be reliably opened while the blade portion 30 a is reliably pressed against the bottom portion 22 of the insertion tube 2. Therefore, it is more preferable.

  Further, the spray holes 42 may be provided in the peripheral wall portion 40 of the exterior cover 6, or may be provided in both the peripheral wall portion 40 and the top wall portion 41. Further, the number and shape of the spray holes 42 are not limited to the above embodiment.
