[0004]
[Problems to be solved by the invention]
By the way, the above-mentioned volatilization device has a structure in which the user breaks the shielding member with another member and uses the liquid formulation by absorbing the liquid formulation into the liquid absorbing member. In the case of such a structure, when the liquid preparation remains in a small amount, it is difficult to flow into the broken portion of the shielding member. For this reason, the above-mentioned volatilization device has room for improvement in that it cannot absorb the liquid preparation smoothly until the end.
[0005]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a volatilization device that can efficiently absorb and volatilize liquid preparations for business purposes.
[0006]
[Means for Solving the Problems]
The object of the present invention is to store a liquid preparation inside, a storage container having an upper opening formed therein, a liquid absorbing member to which the liquid preparation is supplied, and a method in which the liquid absorbing member is used before the liquid absorbing member is used. A volatilization device comprising a shielding member arranged so as not to come into contact with the preparation, and a lid member that can be fitted to the storage container so as to seal the opening in advance, wherein the lid member has A pillar portion is provided that extends into the storage container and houses the liquid absorbing member, and a distal end surface of the pillar portion has a protrusion formed with a hole communicating with the inside of the pillar portion, A toothed projection for breaking a part of the shielding member by lowering the lid member for business use, and the projection is provided in a state where the toothed projection is in contact with or close to the bottom of the storage container. This is achieved by a volatilization device characterized in that there is a gap between the part and the bottom.
[0007]
With the volatilization device having such a configuration, when the user lowers the lid member for errands, the shielding member is broken by the tooth-shaped protrusion formed on the tip end surface of the column portion of the lid member. The liquid preparation contained in the storage container flows into the column from the hole of the projection of the part. Then, the liquid preparation that has flowed in is absorbed by a liquid absorbing member disposed inside the column. The active ingredient in the liquid preparation absorbed by the liquid absorbing member is volatilized in the atmosphere outside the volatilization device.
Further, when the lid member is lowered, the projection and the storage container do not come into contact with each other, so that the liquid formulation smoothly flows into the hole of the projection, and the liquid formulation in the storage container smoothly flows to the end. Can absorb liquid.
In the above-described volatilization device, the liquid absorbing member and the liquid preparation can be prevented from coming into contact with each other in advance by the shielding member. In addition, the volatilization device does not require a user to perform a complicated operation such as removing the shielding member from the storage container and attaching the lid member to the storage container so that the liquid-absorbing member comes into contact with the liquid preparation in business. Is good. At this time, the liquid preparation does not adhere to the user's hand.
Further, since it is not necessary to remove the lid member from the storage container, it is possible to prevent the liquid preparation from spilling or leaking from the volatilization device.
Further, since the shielding member can be broken by rotating the lid member for errands, the user does not need to apply a large force compared to a configuration in which the shielding member is simply pierced perpendicularly.
In addition, since there is no need for a so-called discard cap, which is taken out of the volatilization apparatus and discarded before use, the number of components in the volatilization apparatus can be reduced.
Further, it is possible to easily imagine the usage form of the volatilization device during distribution. The packaging form can be reduced.
[0008]
In the above-mentioned volatilization device, it is preferred that the projection and the tooth-shaped projection are arranged via a gap capable of holding the liquid preparation by surface tension.
In this way, when the remainder of the liquid preparation is small, the liquid preparation in the storage container is held at the tip end surface of the column by the surface tension of the projection and the toothed projection, and the held liquid preparation is projected. Flows into the inside of the column through the hole. For this reason, even if the liquid preparation becomes small, the liquid absorbing member can smoothly absorb the liquid.

The said volatilization apparatus WHEREIN: A 1st engagement protrusion is formed in the said cover member, and the said cover member and the said storage container are engaged with the said storage container by this 1st engagement protrusion. It is preferable to form a second engagement projection capable of holding a position where the projections fit each other.
With this configuration, the first engagement protrusion and the second engagement protrusion are engaged with each other, so that, for example, even when the stopper is not attached in the manufacturing stage, the lid member is fitted to the storage container. It is possible to maintain the state in which the cover member has been rotated, and it is possible to prevent the lid member from rotating unexpectedly. The lid member can be prevented from coming off the storage container due to vibration during distribution.
[0010]
The above-mentioned volatilization device is provided so that the tooth-like projection may be curved along the direction in which the lid member rotates on the distal end surface, and gradually moves forward in the rotation direction of the lid member. This is achieved by a volatilization device characterized by being inclined to increase the amount of protrusion.
With the volatilization device having such a configuration, by lowering the lid member while rotating it, the tooth-shaped projection breaks through the shielding member, and cuts out a predetermined range of the shielding member. The liquid preparation is divided so as to be able to flow in with the other shielding member. For this reason, the liquid preparation in the storage container can flow smoothly.
[0011]
The above-described volatilization device is provided by a volatilization device comprising a stopper that is removable for business while restricting the lid member from lowering before use, and a knob portion is formed on the stopper. Is done.
With the volatilization device having such a configuration, the user can remove the stopper by grasping the knob portion and pulling it out at the time of use.
[0012]
The above-described volatilization device is achieved by a volatilization device, wherein a slit extending in a vertical direction of the pillar portion is formed in the pillar portion.
With a volatilization device having such a configuration, when the shielding member is broken in an errand, the liquid preparation in the storage container flows into the column from the slit as well as from the hole of the protrusion, The liquid preparation can be absorbed more smoothly.
[0013]
The above-mentioned volatilization device opens a supply opening for supplying the liquid preparation to the liquid absorbing member due to a part of the shielding member being broken by the tooth-shaped protrusion, and communicates the inside of the storage container with the atmosphere. This is achieved by a volatilization device, further comprising simultaneous opening means for simultaneously opening the air insertion opening due to breakage of a part of the shielding member.
With the volatilization device having such a configuration, when the user lowers the lid member for errands, a part of the shielding member is broken by the tooth-shaped protrusion formed on the columnar tip surface of the lid member. Since the supply opening for supplying the liquid preparation to the liquid absorbing member is opened, the air insertion opening is opened by breaking a part of the shielding member for communicating the inside of the storage container with the atmosphere. Then, the liquid preparation contained in the storage container flows into the pillar from the hole of the protrusion of the pillar. At this time, the inside of the storage container is communicated with the atmosphere. Therefore, the inflowing liquid preparation is more efficiently absorbed by the liquid absorbing member disposed inside the pillar portion.
[0014]
In the above-mentioned volatilization device, an air hole communicating with the inside of the shielding member and a tooth-like projection are formed at a base end of the pillar portion of the lid member, and the shielding member is The volatilization device is characterized in that the lid member is lowered to be broken by the tooth-shaped protrusion, and a protrusion for communicating the inside of the storage container to the atmosphere through the air hole is further formed. Is done.
With the volatilization device having such a configuration, when the user lowers the lid member for errands, a part of the shielding member is broken by the tooth-shaped protrusion formed on the columnar tip surface of the lid member. At the same time, the projection of the shielding member is broken by the tooth-shaped member formed at the base end of the column of the lid member, and the liquid preparation contained in the storage container through the hole of the projection of the column is used for the column. Inflow inside. At this time, the inside of the storage container is communicated with the atmosphere by the air hole of the lid member and the broken projection of the shielding member. Then, the inflowing liquid preparation is more efficiently absorbed by the liquid absorbing member disposed inside the pillar portion.
In addition, the air hole of the lid member may be either one that is previously opened or one that is opened for business.
[0015]

It is schematically constituted by a lid member 14 provided so as to be fitted to the container 11.
[0018]
The storage container 11 has a main body 11a in which a space for accommodating the liquid preparation L is formed, and a cylindrical erected portion 11b raised upward (upward in FIG. 1) from the main body 11a. Is configured. A portion of the main body 11a surrounded by the standing portion 11b is formed to be open, and an opening 11e is defined by an inner peripheral surface of the standing portion 11b. The standing portion 11b has a male thread portion 23 formed on the outer peripheral surface thereof.
[0019]
The shielding member 13 has a cylindrical shape, and is inserted into the storage container 11 through the opening 11e. At this time, the shielding member 13 is disposed in a state where one end is immersed in the liquid preparation L of the storage container 11, and this end is sealed by the end face 13a. In other words, the shielding member 13 has a cylindrical shape with a bottom.
This shielding member 13 is provided with a thin portion 13b by cutting in the circumferential direction on the outer peripheral side on the inner surface side of the end surface 13a constituting the bottom surface.
[0020]
At the upper end of the shielding member 13, a jaw 13 c is annularly protruded. The jaw 13c is engaged with and fixed to the upper end of the standing portion 11b of the storage container 11 with the shielding member 13 inserted into the storage container 11. At this time, the shielding member 13 is arranged such that the sealed lower end is immersed in the liquid preparation L in the storage container 11 with a slight gap from the bottom 11c of the storage container 11.
In addition, as a material of the shielding member 13, for example, a resin, a metal, a water-resistant laminated material, rubber, wood, bamboo, or the like can be used.
[0021]
The liquid absorbing member 12 has a volatile portion 12a exposed above the lid member 14 and a liquid absorbing portion 12b that absorbs the liquid preparation L.
The lid member 14 has a column 15 extending inside the storage container 11, and the liquid absorbing section 12 b of the liquid absorbing member 12 is arranged inside the column 15.
A plurality of slits 15a extending in the vertical direction are formed on the tip end side of the pillar portion 15.
[0022]
FIG. 2 is a perspective view of a main part of a tip end surface of the pillar shown in FIG.
As shown in FIG. 2, the tip end face 16 of the pillar 15 has a protrusion 16 a in which a hole 16 c communicating with the inside of the pillar 15 is formed. Further, a pair of tooth-shaped protrusions 16b are formed on the outer peripheral side of the tip end surface 16 of the pillar portion 15 along the circumferential direction. In addition, these tooth-shaped protrusions 16b slightly protrude from the protrusion 16a formed at the center of the column portion 15. Further, a plurality of openings 16d are formed on the distal end surface 16 of the pillar portion 15 on the outer peripheral side of the protrusion 16a.
[0023]
The lid member 14 has a head portion 17 that is folded outward at the upper end portion of the pillar portion 15.
An internal thread 21 is formed on the inner peripheral surface of the head 17, and is configured to be screwed into a male thread 23 formed on the standing portion 11 b of the storage container 11.
[0024]
As shown in FIG. 3A, when the cover member 14 grips the head portion 17 and rotates in the direction of arrow R in the figure, the head portion 17 is screwed, whereby the column portion 15 is lowered (see FIG. 3A). (In the direction of the middle arrow P), the tooth-shaped protrusion 16b formed on the front end face 16 bites while slidingly contacting the thin portion 13b of the end face 13a of the shielding member 13, and as shown in FIG. 13 is cut and cut off.
[0025]
As shown in FIGS. 2 and 3, the tooth-shaped protrusion 16 b is formed so as to be curved along a rotation direction R for screwing the lid member 14, and the rotation direction R of the lid member 14 is forward. It is inclined so that the amount of protrusion gradually increases toward.
In other words, in the tooth-shaped protrusion 16b having such a shape, the cover member 14 is rotated to lower the column portion 15, so that the tooth-shaped protrusion 16b easily breaks through the end face 13a of the shielding member 13 and a predetermined range. Is cut out and separated to allow inflow.
[0026]
As shown in FIG. 2, in the volatilization device 10 according to the present embodiment, the protrusion 16 a and the tooth-shaped protrusion 16 b are arranged via a gap capable of holding the liquid preparation L by surface tension. That is, the interval between the projection 16a and the tooth-shaped projection 16b in the column radial direction is formed so that the liquid preparation L can be held by surface tension.
Further, a gap is formed between the protrusion 16a and the bottom 11c in a state where the tooth-shaped protrusion 16b is in contact with the bottom 11c of the storage container 11. In other words, the tooth-shaped protrusion 16b contacts the bottom 11c of the storage container 11, and the protrusion 16a does not contact the bottom 11c with the lid member 14 lowered to the limit.
[0027]
As shown in FIG. 4, an engagement protrusion (first engagement protrusion) 22 is formed on the inner peripheral surface of the cover member 14 on which the female screw portion 21 is formed. As shown in FIG. 5, a pair of engagement projections (second engagement projections) 24 are formed on the outer peripheral surface of the standing portion 11 b of the storage container 11 on which the male screw portion 23 is formed. I have.
When the lid member 14 is fitted to the upright portion 11b and rotated downward, the engagement protrusion 22 on the lid member 14 comes into contact with one of the engagement protrusions 24 on the upright portion 11b. When the cover member 14 is further pushed, the engagement protrusion 22 of the cover member 14 is disposed between the other engagement protrusions 24 over the one of the engagement protrusions 24 in contact with each other, and the rotation of the cover member 14 is restricted. Is done.
[0028]
As shown in FIG. 1, a stopper 19 that is detachable from the standing portion 11 b is provided at a root portion (a lower portion in FIG. 1) of the standing portion 11 b of the storage container 11. As shown in FIG. 6, the stopper 19 has an annular portion 19a partially having a notch 19c, and a knob 19b provided substantially on the opposite side of the notch 19c.
[0029]
The stopper 19 is mounted in such a manner that the notch portion 19c is pressed against the root portion of the upright portion 11b of the storage container 11 so as to be fitted into the annular portion 19a. Then, with the stopper 19 attached to the upright portion 11b, the lowering of the lid member 14 is prevented.
The stopper 19 is detached from the standing portion 11b by gripping and pulling the knob 19b. Then, by removing the stopper 19 from the standing portion 11b, the prevention of the pushing of the lid member 14 is released.
[0030]
As shown in FIGS. 1 and 7, the lid member 14 has a plurality of support pieces 17a formed at an edge of the upper opening 17b at the upper end thereof at intervals in the circumferential direction. The support piece 17a supports the liquid absorbing member 12 upward such that the volatile portion 12a does not contact the upper end surface of the head 17 of the lid member 14 in a state where the liquid absorbing member 12 is mounted on the vaporizing device 10. For this reason, since air appropriately flows into the liquid absorbing part 12b from between the volatilization part 12a and the head 17, volatilization of the liquid preparation L in the volatilization part 12a becomes smooth.
[0031]
Next, the operation of the volatilization device 10 having the above-described configuration in business will be described.
When the volatilization device 10 is used, the stopper 19 attached to the base of the standing portion 11b of the storage container 11 is removed by gripping the knob 19b and pulling the same.
Next, the head 17 of the lid member 14 is gripped and rotated in the screwing direction (the direction of arrow R in FIG. 3).
[0032]
In this case, the engagement protrusion 22 on the lid member 14 disposed between the engagement protrusions 24 on the upright portion 11b gets over the engagement protrusion 24 on the front side in the screwing direction, and the rotation of the lid member 14 is performed. Restrictions are lifted.
When the lid member 14 is further rotated, the pillar 15 of the lid member 14 is lowered while rotating. When the tooth-shaped projection 16b of the tip end surface 16 of the pillar portion 15 bites while slidingly contacting the thin portion 13b of the end surface 13a of the shielding member 13, when it is further rotated, a part of the end surface 13a of the shielding member 13 is cut off and cut off. Can be The end of the shielding member 13 is opened, the tooth-shaped projection 16b abuts on the bottom 11c of the storage container 11, and the projection 16a is disposed with a slight gap from the bottom 11c of the storage container 11. Here, the tooth-shaped protrusion 16b may be configured to be close to the bottom 11c of the storage container 11 (located through a slight gap) as long as the flow of the liquid preparation is not hindered.
[0033]
Thereby, the liquid preparation L stored in the main body 11a of the storage container 11 flows into the inside from the end surface 13a of the shielding member 13, and the hole 16c of the column 15, the opening 16d, and the slit 15a. The liquid also flows into the inside and is absorbed by the liquid absorbing portion 12b of the liquid absorbing member 12.
Then, the liquid preparation L absorbed by the liquid absorbing portion 12b of the liquid absorbing member 12 is sucked up by the liquid absorbing portion 12b and volatilized into the air from the volatilizing portion 12a at the upper end.
[0034]
Here, the volatilization part 12a is arranged with a gap without being in close contact with the upper end of the lid member 14 by the support piece 17a. For this reason, since the space between the support pieces 17a is opened, outside air flows into the storage container 11 appropriately from this opening portion, and the liquid preparation L smoothly absorbs the liquid preparation L into the liquid absorption section 12b of the liquid absorption member 12. Is done.
[0035]
As described above, in the volatilization device according to the present embodiment, the protrusion 16a is disposed at a position slightly spaced from the bottom 11c of the storage container 11 in a state where the column 15 is lowered for business. Have been. Further, the protrusion 16a and the tooth-shaped protrusion 16b are arranged via a gap capable of holding the liquid preparation L by surface tension. For this reason, the volatilization of the liquid preparation L proceeds, the remaining amount of the liquid preparation L in the storage container 11 decreases, and even if the liquid preparation L slightly remains at the bottom 11c of the storage container 11, the liquid preparation L is maintained. Is held by the distal end surface 16 and is reliably absorbed by the liquid absorbing portion 12b of the liquid absorbing member 12 through the hole 16c. Thereby, the volatilization device 10 can smoothly absorb the liquid preparation L in the storage container 11 to the end.
[0036]
In addition, in the volatilization device 10 having the above-described structure, it is troublesome that a user removes the shielding member 13 from the storage container 11 and attaches the lid member 14 to the storage container 11 so that the liquid absorbing member 12 comes into contact with the liquid preparation L in business. Since there is no need to perform a complicated operation, it is possible to improve the usability, and at this time, it is possible to eliminate a problem that the liquid preparation L adheres to the user's hand.
Since there is no need to remove the lid member 14 from the storage container 11, it is possible to prevent the liquid formulation L from leaking from the volatilization device 10.
Further, since the shielding member 13 can be broken by rotating the lid member 14 for errands, the user does not need to apply a large force compared to a configuration in which the shielding member 13 is simply pierced perpendicularly. .
In addition, since it is not necessary to take out and discard a so-called discard cap from the volatilization device 10 before use, the number of components in the volatilization device 10 can be reduced.
Further, it is possible to easily imagine the usage form of the volatilization device 10 at the time of distribution, and it is possible to further reduce the packaging form.
[0037]
The volatilization device 10 is configured such that the engagement protrusion 22 of the cover member 14 and the engagement protrusion 24 of the upright portion 11b are engaged with each other. The state where the member 14 is fitted to the storage container 11 can be maintained. Therefore, it is possible to prevent the lid member 14 from rotating unexpectedly before use.
In the above example, one engagement protrusion 22 is formed on the cover member 14 side, and two engagement protrusions 24 are formed on the standing portion 11b side. As long as the rotation can be restricted, the number and formation positions of the engagement protrusions 22 and 24 are not limited to the above example. For example, two engagement protrusions 22 are formed on the lid member 14 side, and the standing portion 11b is formed. One engagement protrusion 24 may be formed on the side.
[0038]
In addition, by lowering the cover member 14 while rotating it, the tooth-shaped protrusion 16b cuts out a predetermined range of the end surface 13a of the shield member 13 while breaking through the bottom surface 13a of the shield member 13, and the cut-out portion can flow in. And the liquid preparation L in the storage container 11 can flow into the pillar portion 15 smoothly.
Furthermore, the user can remove the stopper 19 by grasping and pulling out the knob 19b of the stopper 19 at the time of use, release the prohibition of rotation of the lid member 14, and make the lid member 14 usable.
In addition, when the shielding member 13 is broken during business, the liquid preparation L of the storage container 11 flows into the column 15 not only from the hole 16c of the projection 16a but also from the slit 15a. The liquid can be more smoothly absorbed by the liquid absorbing portion 12b of the liquid absorbing member 12.
[0039]
Next, a second embodiment according to the present invention will be described with reference to FIGS. FIG. 8 is an overall sectional view of a volatilization device according to a second embodiment of the present invention. In the second embodiment, members and the like having the same configurations and operations as the members and the like already described are denoted by the same reference numerals or corresponding reference numerals in the drawings, and the description thereof will be simplified or omitted.
[0040]
As shown in FIG. 8, a volatilization device 30 according to a second embodiment of the present invention has a projection 13d formed on a shielding member 13, an air hole 17e (see FIG. 9) and a tooth 17 on a head 17 of a lid member 14. A projection 17f is formed.
[0041]
FIG. 9 is a cutaway perspective view of a main part of the shielding member 13 and the lid member 14 shown in FIG.
As shown in FIG. 9, two pairs of protrusions 13 d are formed on the inner periphery of the jaw 13 c near the upper end of the shielding member 13. The protrusions 13d may be formed only in one pair instead of two. The projection 13d has its top plate formed to be thin, and is broken by the toothed projection 17f of the lid member 14 when the lid member 14 is lowered for business. Thereby, the inside of the storage container 11 and the inside of the shielding member 13 communicate with each other. In addition, it goes without saying that the projection 13d may not only be formed with a thin top plate portion but also formed with a thin side plate portion.
[0042]
A pair of air holes 17e are arranged so as to penetrate the bottom of the inner peripheral wall of the head 17 which is the base end of the pillar 15 of the lid member 14. These air holes 17e allow the outer periphery of the pillar portion 15, that is, the inside of the shielding member 13 to always communicate with the outside air (atmosphere).
[0043]
The tooth-shaped protrusions 17f are arranged in two pairs along the circumferential direction on the bottom of the inner peripheral wall of the head 17 outside the air hole 17e. These tooth-shaped projections 17f are arranged so that the top plate portion of the projection 13d of the shielding member 13 can be broken when the lid member 14 is lowered for business as described above. The tooth-shaped protrusion 17f has a rectangular shape as shown in FIG. 9 unlike the triangular tooth-shaped protrusion 16b as shown in FIG. 2, but the shape is as far as possible. Optional.

Accordingly, the simultaneous opening means simultaneously opens the above-described air insertion opening and the supply opening for supplying the liquid preparation L to the liquid absorbing member 12 and, at the same time, a line passing through the tip of the tooth-shaped projection 17f (that is, 8, an imaginary line extending in the lateral direction in FIG. 8) and a line passing through the tip of the toothed projection 16b (that is, an imaginary line extending in the lateral direction in FIG. 8 parallel to the line passing through the tip of the toothed projection 17f). The distance (length) of a perpendicular line (i.e., an imaginary line extending in the vertical direction in FIG. 8) between the line and the line passing through the top surface of the protrusion 13 d (i.e., in FIG. 8) A line perpendicular to the line between the imaginary line extending in the lateral direction and the line passing through the top surface of the thin portion 13b (that is, the imaginary line extending in the lateral direction in FIG. 8 is parallel to the line passing through the top surface of the projection 13d). When the line (that is, the imaginary line extending in the vertical direction in FIG. 8) is extended, the distance of the line ( Is) and so are substantially equal, there needs to be configured.
[0050]
Note that the present invention is not limited to the above-described embodiment, and appropriate modifications and improvements can be made.
For example, as shown in FIG. 13, the volatile portion 32a of the liquid absorbing member 32 may be shaped like a petal. Further, a ring portion 33 to which a decorative portion 34 imitating a leaf is attached at a circumferential interval between the head portion 17 of the lid member 14 and the lower flange portion 17c is fitted, so that an artificial flower-like volatilization device can be obtained. Good. In such a structure, the user can rotate the lid member 14 without touching the volatile portion 32a by gripping the lower flange portion 17c. As shown in FIG. 13, a pair of fitting pieces 17d are provided on the outer peripheral side of the head 17 and the inner peripheral side of the lower flange 17c, and a ring 33 is provided between the head 17 and the lower flange 17c. The ring portion 33 may be sandwiched between the fitting pieces 17d so that the fitting can be securely performed. By doing so, when viewed from the outside of the volatilization device (for example, from the right side in FIG. 13), the ring portion 33 is housed between the head portion 17 and the lower flange portion 17c and cannot be seen, so that the decorativeness is further improved.
