Description

  The present invention relates to a volatilization container.

Conventionally, as a volatilization container, a container main body for storing a volatilizing agent, a closing part for closing the mouth of the container main body so as to be openable, and covering the mouth from the outside of the container main body along the container axial direction, There is known a configuration including a cover cap that is attached to a part, and an impregnated body that is disposed between the mouth part and the cover cap and impregnated with a volatilizing agent (see, for example, Patent Document 1).
A band-shaped cutout portion extending along the circumferential direction of the cover cap is connected to the opening edge of the cover cap via a weakened portion, whereby the container body and the cover cap are relatively aligned along the container axial direction. Movement is restricted.

  When opening the above-described volatilization container, first, the cutout part is separated from the cover cap through the weakening part in an inverted posture in which the container body side is positioned on the upper side and the cover cap side is positioned on the lower side. Next, the container body and the cover cap are moved relatively closer along the container axial direction. Then, the blocking plate is broken by the protrusion formed on the cover cap, so that the volatilizing agent in the container body flows into the inner space of the cover cap. The volatilizing agent that has flowed into the inner space of the cover cap is impregnated in the impregnated body, and then volatilized to the outside of the cover cap through the impregnated body.

Japanese Utility Model Publication No. 61-91228

However, in the above-described volatilization container, since the volatilization agent in the container main body flows out directly to the entire inner space of the cover cap, the volatilization agent may flow out in large quantities. In this case, more volatilizing agent than can be absorbed by the impregnated body flows out into the inner space of the cover cap and stays in the inner space of the cover cap without being absorbed by the impregnated body, so that the volatilizing agent may volatilize in large quantities. There is. As a result, it is difficult to maintain the volatilization effect over a long period of time.
In addition, the volatilizing agent may leak out of the cover cap due to a large amount of the volatilizing agent flowing into the inner space of the cover cap.

  The present invention has been made in view of such circumstances, and suppresses outflow of excess volatilizing agent, can maintain the volatilizing effect over a long period of time, and suppresses leakage of the volatilizing agent to the outside of the cover cap. The purpose is to provide a volatilization container that can be used.

In order to solve the above problems, the present invention proposes the following means.
The volatilization container according to the present invention includes a container main body that contains a volatilizing agent, a top cylindrical cover cap that covers the mouth of the container main body from the outside of the container main body along the container axial direction, and the cover cap. A volatilization container provided with an impregnated body impregnated with a volatilizing agent, wherein the cover cap has a top wall part with which the opening edge of the mouth can contact, and a plane viewed from the container axial direction. In view, a surrounding cylinder portion protruding from a portion located between the impregnated body and the mouth portion of the top wall portion and surrounding the mouth portion from a radially outer side perpendicular to the container axis, The surrounding tube portion is formed with a notch for dividing the surrounding tube portion in the circumferential direction around the container axis, and at least one of the cover cap side and the container body side includes the With the top wall and the opening edge of the mouth abutting, An inner radial direction with respect to parts, the outer side in the radial direction with respect to the surrounding tube section, communicating passage for communicating are formed, said cutout portion, from said tip edges of the surrounding cylindrical portion top wall Extending around the container axis direction in the surrounding tube portion extending to the top, and the communication path is formed in a portion of the top wall portion located in the notch portion. .

  Due to such a feature, the volatilizing agent flows out from the container main body into the cover cap with the opening edge of the mouth portion of the container main body in contact with the top wall of the cover cap. Then, the volatilizing agent that has flowed into the cover cap is guided from the inner side in the radial direction to the mouth part from the inner side in the radial direction to the outer side in the radial direction with respect to the surrounding cylinder part. The volatilizing agent guided to the outer side in the radial direction with respect to the surrounding tube portion is impregnated in the impregnated body by a capillary phenomenon or the like and then volatilizes.

Here, according to the configuration of the present invention, in the plan view along the container axial direction, the mouth portion from the outside in the radial direction is formed on the portion of the top wall portion of the cover cap located between the impregnated body and the mouth portion. Since the surrounding cylinder part which surrounds is projected, it can suppress that the volatile agent which flowed out from the container main body spreads directly in the whole in a cover cap.
In particular, the impregnated body is disposed on the outer side in the radial direction with respect to the surrounding tube portion, and the inner side in the radial direction with respect to the mouth portion and the outer side in the radial direction with respect to the surrounding tube portion are formed only by the communication path. Since it communicates, it can suppress that a volatilizing agent flows out toward an impregnated body in large quantities.
Thereby, since it can suppress that a volatilizing agent flows out more than necessary in a cover cap, it can suppress that a volatilizing agent volatilizes in large quantities. As a result, the volatilization effect can be maintained over a long period of time, and leakage of the volatilizing agent from the cover cap can be prevented.

  And since the notch part which divides the surrounding cylinder part in the circumferential direction is formed, the surrounding cylinder part becomes elastically deformable to radial direction. Thus, for example, when the impregnated body is attached to the outer side in the radial direction with respect to the surrounding tube portion in the cover cap, the impregnated body can be set in a state in which the surrounding tube portion is elastically deformed toward the inner side in the radial direction. . As a result, the mounting work of the impregnated body is simplified and the production efficiency of the volatilization container can be improved.

Further, of the ceiling wall portion, since the communication passage is formed in the portion located in the notch portion, it is possible to simplify the mold for molding the cover cap. As a result, the manufacturing efficiency can be further improved and the cost can be reduced.

  According to the volatilization container which concerns on this invention, while the outflow of an excess volatilizing agent can be suppressed and a volatilizing effect can be maintained over a long period of time, the leakage of the volatilizing agent to the exterior of a cover cap can be suppressed.

The closing plate 34 is formed in a disc shape, and the entire outer peripheral edge thereof is connected to the lower end portion of the seal cylinder 32 via the weakened portion 35. Thereby, the communication inside and outside the container body 2 through the mouth 3 is blocked. In the illustrated example, the closing plate 34 is located below the upper end edge of the mouth portion 3.

As shown in FIGS. 1 to 3, the cover cap 5 has the same shape (square shape) as the container body 2 in a cross-sectional view orthogonal to the container axis O direction, and the inner diameter is above the shoulder portion 13 of the container body 2. The container body 2 is mounted in a size that can be accommodated. Specifically, in the cover cap 5, the inner surface shape of the peripheral wall portion 42 is formed in the same shape as the outer surface shape of the reduced diameter portion 24 in the container body 2.
The peripheral wall portion 42 of the cover cap 5 includes a plurality of main wall portions 45 arranged at intervals along the circumferential direction, and a corner portion 43 that connects the adjacent main wall portions 45 in the circumferential direction. ing. The corner portion 43 and the main wall portion 45 are formed in a protruding arc shape toward the outer side in the radial direction, and are arranged in parallel four by four in the circumferential direction.

As shown in FIG. 2, each corner portion 43 is formed with a pair of slits 47 extending upward and spaced in the circumferential direction. And the part located between each slit 47 among the corner | angular parts 43 comprises the tongue piece part 48 which can be elastically deformed to radial direction.
Each tongue piece 48 is formed with a locking hole 51 in which the protrusion 26 of the container body 2 described above is locked in the opened state of the volatilization container 1 described later. The locking hole 51 extends along the circumferential direction in each tongue piece portion 48.
Furthermore, a plurality of volatilization windows 53 penetrating the corners 43 in the radial direction are formed at intervals in the container axis O direction at portions of the corners 43 positioned above the locking holes 51 described above. ing.

  In the unopened state (unused state) of the volatilization container 1, the cover cap 5 covers the mouth part 3 and the shoulder part 13 of the container body 2 from above, and the circumferential position is shifted with respect to the container body 2. In the state, it is assembled to the container body 2. Specifically, the corner portion 43 of the cover cap 5 and the main wall portion 22 of the container body 2 are aligned in the circumferential direction, the main wall portion 45 of the cover cap 5, the corner portion 21 of the container body 2, Of the opening edge of the cover cap 5 in a state in which is aligned in the circumferential direction, and a portion of the shoulder portion 13 of the container body 2 that is positioned at the corner 21 of the opening end edge of the cover cap 5 Are abutted in the container axis O direction. Thereby, the approach movement along the container axis | shaft O direction of the container main body 2 and the cover cap 5 is controlled.

Here, as shown in FIGS. 1 and 3, the opening edge of the cover cap 5 is formed on the shoulder 13 of the container body 2 described above at the portion located on each main wall 45 of the peripheral wall 42. A housing recess 46 for housing the bulged portion 28 is formed separately. The housing recess 46 is located at the center of the main wall 45 in the circumferential direction, and is formed in an arcuate shape that protrudes upward along the outer shape of the bulging portion 28. The bulging portion 28 and the housing recess 46 described above constitute a restricting portion that restricts relative movement of the container body 2 and the cover cap 5 in the circumferential direction.
Accordingly, the volatilization container 1 is relatively moved in the circumferential direction between the container body 2 and the cover cap 5 in a state (regulated state) in which the bulging portion 28 of the container body 2 is housed in the housing recess 46 of the cover cap 5. The container body 2 and the cover cap 5 are configured to be relatively rotatable in the circumferential direction in a state where the bulging portion 28 is separated from the housing recess 46 (regulation release state).

As shown in FIGS. 2 and 3, in the top wall portion 41 of the cover cap 5, the weakening portion 35 is broken at the portion facing the weakening portion 35 of the closing portion 4 in the container axis O direction. An opening 61 for opening the portion 3 is provided. The open portion 61 is formed in a cylindrical shape extending downward, and the lower end edge thereof is inclined toward a direction intersecting the container axis O direction.
In addition, a communication groove 62 that penetrates the opening 61 in the radial direction is formed in a part of the opening 61 in the circumferential direction. The communication groove 62 has a slit shape that extends over the entire opening 61 along the container axis O direction. In the illustrated example, the communication groove 62 is formed in the short part of the open part 61 having the shortest length along the container axis O direction.

  As shown in FIG. 1 to FIG. 3, a surrounding cylinder portion 64 that surrounds the opening portion 61 protrudes from a portion of the top wall portion 41 that is located radially outside the opening portion 61. . The surrounding cylinder portion 64 is located on the outer side in the radial direction than the closing portion 4 described above, and the length along the container axis O direction is shorter than the opening portion 61 described above.

  As shown in FIGS. 1 and 8, the surrounding cylinder portion 64 is formed with a pair of notches 66 extending along the container axis O direction at portions facing in one direction in the radial direction. Each notch part 66 is formed over the entire container axis O direction in the surrounding cylinder part 64 from the lower end edge (protruding edge) of the surrounding cylinder part 64 to the top wall part 41, and inside and outside of the surrounding cylinder part 64. It communicates in the radial direction. And the surrounding cylinder part 64 can be elastically deformed to radial direction by being divided by the notch part 66 in the circumferential direction.

  As shown in FIGS. 1 and 2, the surrounding cylinder portion 64 is formed with an engagement piece 60 extending downward in a portion facing in the other direction orthogonal to the above-described one direction in the radial direction. ing. The engagement piece 60 has an engagement portion 60 a that can be engaged with the neck ring 27 of the container body 2 from below. The engaging portion 60a is spaced downward with respect to the neck ring 27 when in the restricted state, and is engaged with the neck ring 27 from below when in the restricted state.

  As shown in FIGS. 1 and 8, a communication passage 71 that is recessed upward is formed in a portion of the top wall 41 that is located in each notch 66. The communication path 71 is a long groove extending along the radial direction, and in a plan view as viewed from the container axis O direction, the radial inner end portion is close to the open portion 61 inside the mouth portion 3, and the radial outer side. The end portion is located outside the surrounding tube portion 64. In the illustrated example, the communication passage 71 is formed at two locations corresponding to the notch portions 66.

  A support cylinder 65 that supports an impregnated body 72 (described later) from the outside in the radial direction is formed in a portion of the top wall 41 that is located outside in the radial direction with respect to the surrounding cylinder part 64. The support cylinder 65 is disposed at a radial interval with respect to the surrounding cylinder part 64 and surrounds the surrounding cylinder part 64. The support cylinder 65 is positioned on the outer side in the radial direction from the neck ring 27 of the container main body 2, and the length along the container axis O direction is longer than the surrounding cylinder part 64.

  As shown in FIGS. 2 and 3, an impregnation body 72 that impregnates a volatilizing agent that flows out from the container body 2 into the cover cap 5 is mounted between the surrounding cylinder portion 64 and the support cylinder 65. The impregnated body 72 has a cylindrical shape, and an upper end portion thereof is held between the surrounding tube portion 64 and the support tube 65, and a lower end portion protrudes below the surrounding tube portion 64 and the support tube 65. In the illustrated example, the lower end portion of the impregnated body 72 faces the volatilization window 53 in the radial direction. The impregnated body 72 is formed of a porous material such as a filter paper or a sponge body.

Next, the opening method of the volatilization container 1 mentioned above is demonstrated.
The volatilization container 1 of the present embodiment is always used in a state as shown in FIG. 5, that is, in an inverted position upside down with respect to the state of FIG. The Therefore, the opening method described below will be described in an inverted posture in which the cover cap 5 side is the lower side and the container body 2 side is the upper side. In the unopened state, as described above, the portion of the opening edge of the cover cap 5 that is located on the main wall portion 45 of the peripheral wall portion 42 and the portion of the shoulder portion 13 of the container body 2 that is located at the corner portion 21. Since they are abutted in the container axis O direction, the close movement of the container body 2 and the cover cap 5 along the container axis O direction is restricted. Moreover, since the bulging part 28 of the container main body 2 is in the restricted state in which it is accommodated in the accommodating recess 46 of the cover cap 5, the movement of the container main body 2 and the cover cap 5 in the circumferential direction is also restricted. .

  To open the volatilization container 1 described above, as shown in FIGS. 6 to 8, the container body 2 and the cover cap 5 are relatively rotated in the circumferential direction, and the corner portion 21 of the container body 2 and the cover cap are rotated. 5 corners 43 are aligned with each other in the circumferential direction. When the container body 2 and the cover cap 5 are relatively rotated in the circumferential direction, the bulging portion 28 of the container body 2 is released from the regulation recess 46 of the cover cap 5 and the opening edge of the cover cap 5 is released. Touch the top. In the illustrated example, the container body 2 and the cover cap 5 are rotated 45 ° in the circumferential direction from the unopened state described above. In the present embodiment, since the engagement piece 60 of the cover cap 5 is engaged with the neck ring 27 of the container main body 2 when the restriction is released, the container main body 2 and the cover cap 5 are rotated. It is possible to prevent the container body 2 from rattling against the cover cap 5 and the container body 2 from coming off the cover cap 5.

  In this state, the container main body 2 is inserted into the cover cap 5 and the container main body 2 and the cover cap 5 are brought close to each other along the container axis O direction, so that the reduced diameter portion 24 of the container main body 2 is within the cover cap 5. To enter.

  Thereafter, the weakened portion 35 is broken by the opening portion 61 of the cover cap 5 abutting against the weakened portion 35. Then, the closing plate 34 is detached from the seal cylinder 32, the opening 3 of the container body 2 is opened, and the volatilizing agent stored in the container body 2 flows out into the cover cap 5. At this time, the container main body 2 and the cover cap 5 are brought close to each other until the connecting ring 33 of the closing plate 34 contacts the top wall 41 of the cover cap 5. Thereby, in the cover cap 5, between the mouth part 3 of the container main body 2 and the impregnated body 72 is partitioned by the surrounding cylinder part 64, and the communication path 71 extends the mouth part 3 of the container main body 2 in the radial direction. By being arranged so as to straddle, the inner side in the radial direction with respect to the mouth portion 3 and the outer side in the radial direction with respect to the surrounding tube portion 64 communicate with each other only through the communication path 71.

  Further, when the container main body 2 and the cover cap 5 are brought close to each other, the container main body 2 enters the cover cap 5 while the tongue 26 of the cover cap 5 is elastically deformed radially outward by the protrusion 26. To do. When the connecting ring 33 of the closing plate 34 contacts the top wall 41 of the cover cap 5, the tongue piece 48 is restored and the protrusion 26 is locked in the locking hole 51. Further, the locking projection 25 of the container body 2 is accommodated in the accommodating recess 46 of the cover cap 5. Thereby, the relative movement of the container body 2 and the cover cap 5 in the opened state is restricted.

  Here, as shown in FIG. 8, the volatilizing agent that has flowed out of the container body 2 into the cover cap 5 passes through the gap between the opening edge of the mouth portion 3 (the connecting ring 33 of the closing portion 4) and the communication passage 71. Then, it is guided so as to ooze out to the outside in the radial direction with respect to the mouth portion 3. Thereafter, the volatilizing agent guided to the outside in the radial direction with respect to the mouth portion 3 is guided through the communication path 71 so as to ooze out to the outside in the radial direction with respect to the surrounding tube portion 64. The volatilizing agent is impregnated between the surrounding tube portion 64 and the support tube 65 by a capillary phenomenon or the like at an outer end portion in the radial direction of the communication passage 71 (a portion located outside the surrounding tube portion 64). The body 72 is impregnated. The volatilizing agent impregnated in the impregnated body 72 is led out through the volatilization window 53 of the cover cap 5 while volatilizing.

As described above, according to the present embodiment, the surrounding cylinder portion 64 surrounding the mouth portion 3 from the outside in the radial direction is formed in the cover cap 5 between the impregnated body 72 and the mouth portion 3 of the container body 2. Therefore, it is possible to suppress the volatilizing agent from spreading directly over the entire cover cap 5.
In particular, the impregnated body 72 is disposed on the outer side in the radial direction with respect to the surrounding tube portion 64, the inner side in the radial direction with respect to the mouth portion 3, and the outer side in the radial direction with respect to the surrounding tube portion 64. Since the communication path 71 communicates, a large amount of the volatilizing agent can be suppressed from flowing toward the impregnated body 72.
Thereby, since it can suppress that a volatilizing agent flows out more than necessary in the cover cap 5, it can suppress that a volatilizing agent volatilizes in large quantities. As a result, the volatilization effect can be maintained for a long time, and the volatilizing agent can be prevented from leaking directly from the volatilization window 53.

  In addition, according to the present embodiment, since the notched portion 66 that divides the surrounding tube portion 64 in the circumferential direction is formed, the surrounding tube portion 64 can be elastically deformed in the radial direction. Thus, for example, when the impregnated body 72 is attached to the cover cap 5, the impregnated body 72 is set between the surrounding tube portion 64 and the support tube 65 in a state in which the surrounding tube portion 64 is elastically deformed toward the inside in the radial direction. can do. As a result, the mounting work of the impregnated body 72 is simplified, and the production efficiency of the volatilization container 1 can be improved.

  Furthermore, in this embodiment, since the above-mentioned communication path 71 is formed in the part in which the notch part 66 is located in the surrounding cylinder part 64, the metal mold | die for shape | molding the cover cap 5 is simplified. Can do. As a result, the manufacturing efficiency can be further improved and the cost can be reduced.

As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
For example, when the above-described embodiment is adopted, the cross-sectional shape orthogonal to the container axis O direction in the container body 2 and the cover cap 5 is not limited to the above-described square shape, and can be changed as long as it is a non-circular shape. It is. For example, it may be triangular, pentagonal, elliptical or semicircular. In other words, the radii of the outer peripheral surface of the body portion 12 and the inner peripheral surface of the peripheral wall portion 42 may not be the same over the entire circumference. In addition, the design of the contact range in the circumferential direction between the shoulder 13 of the container body 2 and the opening edge of the cover cap 5 can be changed as appropriate.

Moreover, in embodiment mentioned above, the container main body 2 along the circumferential direction and the container axis | shaft O direction by abutting the shoulder part 13 of the container main body 2, and the opening edge of the cover cap 5 in an unopened state, Although the configuration in which the relative movement with the cover cap 5 is restricted has been described, the configuration is not limited thereto. That is, the relative movement along the container axis O direction between the container body 2 and the cover cap 5 in the unopened state may be restricted so that at least the closed portion 4 can be prevented from being opened unexpectedly.
In this case, for example, a restriction member that restricts relative movement of the container body 2 and the cover cap 5 in the direction of the container axis O is detachable or breakable, and the restriction by the restriction member is released. A configuration in which the container body 2 is allowed to enter the cover cap 5 can be employed. In addition, a rib that contacts the shoulder 13 of the container body 2 is provided in the cover cap 5 to restrict relative movement between the container body 2 and the cover cap 5 along the container axis O direction. When the container 2 is rotated in the circumferential direction, the container body 2 is provided with an accommodating portion that accommodates the rib described above and releases the restriction on relative movement between the container body 2 and the cover cap 5 along the container axis O direction. It does not matter as a structure arrange | positioned in the part 12 and the shoulder part 13. FIG.

Further, in the above-described embodiment, the configuration in which the closing portion 4 opens the mouth portion 3 by breaking the weakened portion 35 has been described. It is. In this case, the closing part may be configured so that the mouth part is opened in a state where the container body and the cover cap are assembled and the mouth part of the container body and the top wall part of the cover cap are in contact with each other. For example, after peeling off the closed part by hand, the mouth part of the container body and the top wall part of the cover cap are brought into contact (details will be described later), or the mouth part of the container body and the top wall part of the cover cap are The structure which pulls out the obstruction | occlusion part in the state contact | abutted, and open | releases an opening | mouth part may be sufficient.
Furthermore, the opening portion 61 is not limited to the cylindrical shape, and can be appropriately changed in design as long as the opening portion 3 is opened by pressing and removing the closing portion 4 such as a cross-shaped rib. .

  Furthermore, in the volatilization container of the present invention, in addition to the embodiment described above, for example, the following configurations can also be adopted. That is, in the volatilization container 100 shown in FIG. 9, a closing part 102 such as an aluminum seal that closes the mouth part 3 is detachably attached to the mouth part 3 of the container body 101 on the opening edge of the mouth part 3. ing.

On the other hand, as shown in FIG. 10 and FIG. 11, the cover cap 110 of the volatilization container 100 has a top tube shape, and protrudes downward from the top wall portion 111 and the outer peripheral edge of the top wall portion 111. It has a support cylinder 112 and a pedestal 115 that protrudes from the outer peripheral edge of the top wall 111 toward the outside in the radial direction.
The top wall 111 has a circular shape in plan view along the container axis O direction. An encircling tube portion 113 that protrudes downward is formed in a portion of the top wall portion 111 that is located on the radially inner side of the support tube 112.

  The surrounding cylinder portion 113 has an inner diameter larger than the outer diameter of the mouth portion 3 of the container main body 101, and surrounds the mouth portion 3 from the outside in the radial direction in a plan view along the container axis O direction. On the inner peripheral surface of the surrounding tube portion 113, a locking recess 113a is formed in which a locking projection 105 formed on the mouth portion 3 of the container body 101 is fitted undercut.

Here, in the surrounding cylinder portion 113, a pair of notches 117 extending along the container axis O direction is formed in a portion opposed in one direction in the radial direction. Each notch 117 is formed over the entire container axis O direction of the surrounding tube portion 113, and communicates the inside and outside of the surrounding tube portion 113 in the radial direction.
Further, a communication passage 119 that is recessed upward is formed in a portion of the top wall portion 111 of the cover cap 110 located in each notch 117. The communication path 119 is a long groove extending along the radial direction, and an inner end portion in the radial direction is located in the mouth portion 3, and an outer end portion in the radial direction is located outside the surrounding cylinder portion 113.

  The support cylinder 112 is disposed at a radial distance from the surrounding cylinder portion 113 and surrounds the entire circumference of the surrounding cylinder portion 113. In the cover cap 110, a cylindrical impregnated body 72 is mounted between the support cylinder 112 and the surrounding cylinder portion 113. The impregnated body 72 has an upper end portion disposed between the support tube 112 and the surrounding tube portion 113 and a lower end portion projecting downward from the support tube 112 and the surrounding tube portion 113. In the radial direction, the impregnated body 72 has a thickness smaller than the distance between the surrounding tube portion 113 and the support tube 112 and is disposed on the support tube 112 side (near the outer periphery).

  The pedestal portion 115 is formed in a flange shape extending over the entire circumference of the top wall portion 111, and the upper surface thereof is grounded together with the upper surface of the top wall portion 111 in the usage state (inverted posture) of the volatilization container 1. It has become. Thereby, the volatilization container 1 can be earth | grounded stably. The shape of the pedestal portion 115 can be appropriately changed in design. For example, the pedestal portion 115 may be provided intermittently in the circumferential direction, or may be erected above the top wall portion 111.

In order to open the volatilization container 100 configured in this way, first, as shown in FIG. 9, the container body 101 from which the cover cap 110 has been removed is placed in an upright posture with the mouth 3 facing upward. Then, the closing part 102 that closes the mouth part 3 is peeled off, and the mouth part 3 is opened.
Next, the surrounding cylinder part 113 of the cover cap 110 is undercut fitted into the mouth part 3 of the container body 101. At this time, the container main body 101 and the cover cap 110 are undercut fitted with the opening edge of the mouth 3 in the container main body 101 in contact with the top wall 111 of the cover cap 110.

  In this state, as shown in FIG. 12, the volatilization container 100 is turned upside down so that the mouth 3 is in an inverted posture. Then, the volatile agent accommodated in the container main body 101 flows out into the cover cap 110. The volatilizing agent that has flowed into the cover cap 110 passes through the gap between the opening edge of the mouth portion 3 and the communication passage 119 and is guided to ooze out toward the radially outer side with respect to the surrounding tube portion 113. . The volatilizing agent is introduced to the impregnated body 72 by a capillary phenomenon or the like at the outer end in the radial direction of the communication passage 119 after the volatilizing agent is guided radially outward with respect to the surrounding tube portion 113. Volatilizes from the impregnated body 72.

According to this configuration, the same effects can be achieved as in the above-described embodiment. In this case, since the inner side in the radial direction with respect to the mouth portion 3 and the outer side in the radial direction with respect to the surrounding tube portion 113 communicate with each other only through the communication path 119, the impregnated body 72 is covered from the outer side in the radial direction. Even if such a large cover cap is not used and the impregnated body 72 is exposed to the outside as in the illustrated example, the volatilizing agent can be prevented from leaking to the outside. As a result, the cover cap 110 can be simplified and made compact.
Further, since the surrounding tube portion 113 is divided in the circumferential direction by the notch portion 117, when the surrounding tube portion 113 is undercut fitted into the mouth portion 3 of the container body 101, The surrounding tube portion 113 can be elastically deformed by copying it. Thereby, the assembly | attachment property of the container main body 101 and the cover cap 110 can be improved.
Furthermore, even when the thickness of the impregnated body 72 is smaller than the distance between the surrounding tube portion 113 and the support tube 112, the surrounding tube portion 113 is elastically deformed in the radial direction as in the above-described embodiment. By setting the impregnated body 72, the mounting work of the impregnated body 72 can be performed more easily.

  Further, in the configuration of FIGS. 9 to 12 described above, the configuration in which the cover cap 110 and the container main body 101 are assembled by undercut fitting has been described. However, the assembly method can be appropriately changed, for example, FIG. As shown in FIG. 14, it may be assembled by screwing.

Specifically, in the volatilization container 120 shown in FIGS. 13 and 14, the surrounding cylinder portion 131 of the cover cap 130 has a double cylinder shape, and is spaced radially outward from the inner cylinder 132 and the inner cylinder 132. The outer cylinder 133 is provided with a gap, and the inner cylinder 132 and a connecting ring 134 that connects lower end edges of the outer cylinder 133 are provided.
The inner cylinder 132 has an inner diameter larger than the outer diameter of the mouth portion 3 of the container body 101. On the inner peripheral surface of the inner cylinder 132, a female screw portion 132a to which a male screw portion 135 formed in the mouth portion 3 of the container body 101 is screwed is formed.

A pair of notches 137 extending along the container axis O direction is formed in the surrounding cylinder portion 131 at portions facing in one direction in the radial direction. Each notch part 137 is formed over the entire container axis O direction of the surrounding cylinder part 131 and communicates the inside and outside of the surrounding cylinder part 131 in the radial direction.
In the illustrated example, the communication passage 139 has a radially inner end located in the inner cylinder 132 and a radially outer end located outside the surrounding cylinder 131 (outer cylinder 133). Yes. Of the inner tube 132, the outer tube 133, and the connecting ring 134 of the surrounding tube portion 131, the edge portions exposed in the notch portion 137 are closed by being connected to each other (see FIG. 15). .

  In order to open the volatilization container 120 configured in this way, first, the blocking part 102 (see FIG. 9) is peeled off, the mouth part 3 is opened, and then the cover cap 130 is attached to the mouth part 3 of the container body 101. The inner cylinder 132 is screwed. At this time, the container main body 101 and the cover cap 130 are brought close to each other until the opening edge of the mouth portion 3 in the container main body 101 contacts the top wall 111 of the cover cap 130.

  In this state, as shown in FIG. 15, the volatilization container 120 is turned upside down so that the mouth 3 is in an inverted posture. Then, the volatilizing agent accommodated in the container main body 101 flows out into the cover cap 130. The volatilizing agent that has flowed into the cover cap 130 is guided to the outside of the surrounding tube portion 131 through the gap between the opening edge of the mouth portion 3 and the communication path 139, and then volatilizes via the impregnated body 72. .

  According to this configuration, the same effects as the above-described embodiment can be obtained, and the container body 101 and the cover cap 130 can be reliably assembled by screwing.

  Moreover, although the structure of FIGS. 13-15 mentioned above demonstrated the structure which screws the cover cap 130 after peeling the obstruction | occlusion part 102, it is not restricted to this. For example, like the volatilization container 150 shown in FIGS. 16 and 17, the mouth 3 of the container main body 101 is closed by a film-like closing part 152, and among the top wall part 111 of the cover cap 130, You may arrange | position the opening part 151 which fractures | ruptures the closure part 152 and opens the opening | mouth part 3 in the part which opposes in the container axis O direction. In the example shown in the drawing, the open portion 151 has a rod shape extending along the container axis O direction, and its lower end portion is tapered.

  In order to open the volatilization container 150 configured in this way, as shown in FIG. 17, the volatilization container 150 is turned upside down with the mouth 3 of the container body 101 closed by the closing part 152, and the container body The inner cylinder 132 of the cover cap 130 is screwed into the mouth 3 of the 101. Thereby, the opening part 151 of the cover cap 130 hits the blocking part 152, the blocking part 152 is broken, and the mouth part 3 is opened. Thereafter, the volatilizing agent is volatilized through the impregnated body 72 in the same manner as described above. In addition, after breaking the closing part 152 by the opening part 151, it may be turned upside down from the upright position to the inverted position.

  According to this configuration, in addition to the same effects as the volatilization container 120 shown in FIGS. 13 to 15 described above, there is no need to peel off the blocking portion 152, so that the operability at the time of opening is improved. be able to.
