Description

  The present invention contains various liquids (skin water, perfume, ink, etc.) such as a cosmetic tool such as an eyeliner, a pen (writing tool), and a stamp, and supplies the liquid toward an application unit. It relates to a supply device.

  As a liquid supply apparatus as described above, for example, Patent Document 1 discloses that a liquid is contained in a pen-type main body, and this is disposed on the leading end side of the relay core via a porous relay core disposed in the center. The structure supplied to the provided application part is disclosed. Specifically, the cavity of the main body is divided into a liquid storage chamber and a reservoir chamber for storing liquid via a partition, and the relay core is inserted at a predetermined interval in the center of the partition. A through hole is formed. Further, the partition wall is formed with a partition wall extending portion that extends toward the liquid storage chamber and has a gap that can hold the liquid by capillary force between the relay core and the partition wall. The extension portion is formed to be higher than the liquid stored in the liquid storage chamber when the application portion is directed downward. Further, a liquid absorber that penetrates the relay core and absorbs the liquid is disposed in the reservoir chamber.

Japanese Patent No. 3909775

  In the above-described liquid supply device, in a state where the application unit faces downward, the partition extension portion prevents the liquid from coming into contact with the relay core, so that the application unit side does not become liquid rich. However, when the posture changes or the temperature changes (temperature rise), the liquid stored in the liquid storage chamber enters the gap between the partition wall extension and the relay core from the end of the partition wall extension. Further, since the relay core is formed of a porous material, the liquid that has entered is absorbed into the relay core and moves to the application portion side where the capillary force is strong.

Further, with respect to the liquid absorber disposed in the reservoir chamber on the application unit side, when there is no change in posture or temperature, there is no movement of the liquid in the liquid storage chamber, and the liquid absorber is in an unsaturated state (saturated It is desirable to be in an inaccessible state.
Therefore, for the capillary force of the relay core and the liquid absorber, it is desirable to reduce the liquid absorber and increase the difference between them to some extent, but the strength of the capillary force of the liquid absorber is Due to instability (porosity varies), it is difficult to set the difference between the two in a certain range during mass production. Specifically, if the difference between the two becomes too large, it becomes impossible to absorb the ink pushed into the relay core due to a change in posture or temperature, and if the difference between the two becomes too small, In this case, the liquid absorber easily approaches a saturated state, and the function of absorbing the liquid is impaired. That is, there is a problem that the capillary force of the liquid absorber has a large degree of variation for each member, and for the reason described above, the application part side tends to be in a liquid rich state.

  The present invention has been made paying attention to the above-described problem. The liquid storage chamber and the reservoir chamber are divided by a partition wall formed with a through hole, and the liquid storage chamber is inserted through a relay core inserted through the through hole. In the liquid supply device that supplies the liquid contained in the room to the coating unit provided at the tip of the relay core, the liquid supply that does not become a liquid-rich state on the coating unit side even if a change in posture or temperature changes. An object is to provide an apparatus.

  In order to achieve the above-described object, a liquid supply apparatus according to the present invention divides a main body having a cavity portion and the cavity portion into a liquid storage chamber in which liquid is stored and a reservoir chamber in communication with the atmosphere, A partition wall having a through-hole formed in the central portion, an application portion that is provided in the main body and applies the liquid in the liquid storage chamber, supplies the liquid in the liquid storage chamber to the application portion, and A porous relay core that is inserted into the inner wall with a predetermined gap, and protrudes from the partition wall toward the liquid storage chamber side, and has a predetermined clearance from the outer peripheral surface of the relay core. A partition wall extending portion through which the relay core is inserted so as to protrude into the chamber, and the partition wall extending portion is in contact with two or more locations with respect to the inserted relay core on the liquid storage chamber side A portion of the relay core is formed. The peripheral surfaces, wherein the cover a range extending at least from the bulkhead to the contact portion is covered.

  According to the liquid supply device having the above-described configuration, the liquid in the liquid storage chamber has a gap between the through hole formed in the partition and the relay core, and a gap between the partition extension and the relay core. The gas-liquid exchange operation is performed through the outer peripheral surface of the relay core projecting outside the partition wall extension portion (the portion where the cover is not covered) and flows into the relay core and supplied to the coating unit via the relay core. . In this case, even if the posture is changed and the application part is directed downward, the partition wall extending part does not cause the liquid to flow into the reservoir chamber, and the application part does not become liquid-rich. In addition, even if the orientation changes, such as when it is turned sideways, or when the temperature rises (internal pressure rises), the contact portion is formed at the end of the partition wall extension portion. Since the cover is covered on the outer peripheral surface of the relay core as described above even if liquid flows in from this portion, it is difficult for the liquid to flow into the gap between the relay core and the relay core. It does not flow in and the application part does not become liquid rich. In other words, even if the application part becomes downward due to temperature rise or posture change, the liquid does not flow into the relay core from the gap between the partition wall extension part and the relay core. A rich state can be prevented.

  In the configuration described above, the reservoir chamber is provided with a liquid absorber that penetrates the relay core and can be impregnated with liquid, and the cover is covered on the outer peripheral surface of the relay core in the liquid absorber. Is preferred.

  In such a configuration, even if the liquid flows into the gap between the partition wall extending portion and the relay core, and the liquid flows into the reservoir chamber through the through hole formed in the partition wall, the liquid absorber Therefore, it is prevented that the liquid is rich on the application part side. In addition, since the cover is covered on the outer peripheral surface of the relay core that comes into contact with the liquid absorber, the liquid flowing through the relay core is not absorbed by the liquid absorber. The application part side is not in a liquid poor state.

  In the configuration in which such a liquid absorber is provided in the reservoir chamber, it is preferable that a region that does not cover the cover is provided on a part of the outer peripheral surface of the relay core in the liquid absorber.

  In such a configuration, when a large amount of liquid flows into the relay core, the liquid is absorbed by the liquid absorber through a portion that does not cover the cover. Can be effectively suppressed.

  Moreover, in the above-described configuration, it is preferable that a contact portion that contacts two or more locations with respect to the relay core to be inserted is formed in the through hole of the partition wall.

  In such a configuration, since it is difficult for the liquid to flow into the reservoir chamber from the gap between the through hole of the partition wall and the relay core, and the internal pressure of the partition wall portion is relatively increased, the posture has been changed, for example, the sideways. Even if the temperature rises (internal pressure rise) in the state, the liquid can be more difficult to flow from the end of the partition wall extension part into the gap between the partition wall extension part and the relay core. It will not be wasted.

  Moreover, in the above-described configuration, it is preferable that the outer peripheral surface of the relay core protruding from the partition extending portion is covered with the cover member except for the protruding end region.

  In such a configuration, the amount of liquid flowing into the inside from the outer peripheral surface of the relay core protruding from the partition extending portion can be limited even if there is a change in posture, temperature rise, etc. A rich state can be effectively prevented, and liquid is not wasted.

  In the above-described configuration, the liquid absorber is preferably set so that the porosity on the liquid storage chamber side is low and the porosity on the application unit side is high.

  In such a configuration, even if the liquid flows into the liquid absorber through the through hole of the partition wall, the liquid is held on the liquid storage chamber side having a low porosity. A liquid seal is formed on the side. For this reason, the inflow of the liquid from the liquid storage chamber side can be prevented, and the wasteful consumption of the liquid can be suppressed.

  Further, in the above-described configuration, the initial storage amount of the liquid stored in the liquid storage chamber is set to a position that does not contact the relay core protruding from the partition wall extension portion in a state where the main body is placed on a horizontal plane. It is preferable.

  In such a configuration, the liquid stored in the liquid storage chamber does not flow in a large amount to the application unit side via the relay core even when the main body is placed in a horizontal state or the application unit is moved downward due to the posture change. In addition, since the amount flowing into the gap between the partition wall extending portion and the relay core is also reduced, it is possible to effectively prevent the liquid rich state on the application portion side and to suppress the wasteful consumption of the liquid. It becomes.

  In the configuration described above, the initial amount of liquid stored in the liquid storage chamber is such that the main body is placed on a horizontal surface so that the application unit faces upward, and is on the end surface of the partition wall extension. It is preferable that the position is set so as not to contact.

  In such a configuration, in a state where the main body is placed on a horizontal surface with the application portion facing upward, the liquid stored in the liquid storage chamber is in the gap between the partition wall extension portion and the relay core. The liquid rich state on the application part side can be surely prevented without flowing in, and wasteful consumption of liquid can be suppressed. In addition, even if the temperature rises suddenly in the above state or the posture is changed from that state, the liquid volume to be accommodated is small and it is difficult for the liquid to flow into the gap between the partition wall extending portion and the relay core. Therefore, it is possible to effectively prevent the liquid rich state on the application part side.

  According to the present invention, it is possible to obtain a liquid supply apparatus that does not become a liquid-rich state on the application unit side even when a posture change, a temperature change, or the like occurs.

Embodiments of the present invention will be specifically described below with reference to the drawings.
FIG. 1 is a diagram showing a first embodiment of the present invention. The liquid supply apparatus according to this embodiment is configured as an eyeliner that is a cosmetic tool, and includes a main body 1 having a hollow portion and formed in, for example, a cylindrical shape. The hollow portion of the main body 1 includes a storage chamber 3 in which a coating liquid (eyeliner liquid) H is stored by a partition wall 2 arranged in a direction orthogonal to the axial direction, and a reservoir chamber that receives ink flowing out of the storage chamber 3. It is divided into four. Further, a cap-shaped tail plug 5 detachably attached to the main body 1 is attached to the tail end side of the main body 1, and a tip 7 having an opening 7 a is formed on the front end side of the main body 1. A coating portion 8 is attached to the reservoir chamber 4 with an air communication hole 7b opened in the reservoir chamber 4 interposed therebetween.

  The partition wall 2 is configured by press-fitting a disk-shaped member into the inner peripheral surface of the main body 1. As shown in FIG. 1 (c), an elongated relay core 10 is predetermined at the center. The through hole 2a is formed so as to be inserted with a gap G (a gap that allows the atmosphere to move to the storage chamber 3 side and exchange gas and liquid). The relay core 10 is formed as a porous rod-shaped member by, for example, converging and compressing a large number of fibers parallel to the axial direction, and the surface thereof, excluding the rear end region 10a, A cover 11 made of a material such as a resin through which the coating liquid cannot pass is covered.

  In this case, the relay core 10 does not exchange gas and liquid inside (does not form an air passage) so that the coating liquid H stored in the storage chamber 3 by capillary force can be supplied toward the coating unit 8 with high sensitivity. Thus, it is formed so that the porosity is as low as possible. Further, the cover 11 may be made of a material that does not allow the coating liquid to substantially flow into the interior, and may be coated on the surface thereof. For example, the rear end region 10a is masked and impregnated with a resin liquid. The relay core can be formed by covering the surface of the relay core or by inserting the relay core 10 into a liquid-impermeable cover body previously formed in a cylindrical shape. For this reason, the coating liquid can flow into the relay core 10 covered with the cover 11 from the rear end region 10a.

  The partition wall 2 protrudes toward the storage chamber 3 along the relay core 10 and includes a partition wall extending portion 2b having a clearance so as to maintain the predetermined gap G toward the tail plug 5 as it is. (In the figure, such a gap is indicated by G ′). In this case, the partition wall extending portion 2b may be integrally formed of the same material as that of the partition wall 2, or may be configured by integrating different members.

  The application part 8 is connected to the front end of the relay core 10, and the rear end side protrudes into the storage chamber 3 from the rear end opening 2c of the partition wall extension part 2b (projects into the tail plug 5). The cover 11 is covered except for the outer peripheral surface of the rear end region 10a of the protruding relay core 10. In this case, the application unit 8 provided on the distal end side may be configured so that the application liquid H accommodated in the storage chamber 3 can be applied along the eyeline. For example, the same material as the relay core 10 is used. Thus, it is possible to configure the relay core with a diameter that is integrated with the tip of the relay core, or that can be connected to the front end of the relay core, such as a brush-like member or a member having moisture retention. Moreover, the capillary force in the application part 8 is set to be larger than that of the relay core 10, and the coating liquid that has entered the relay core moves into the application part 8 and can be applied from the surface thereof. . Note that the capillary force of the relay core 10 is set to be substantially uniform along the longitudinal direction, but it is preferable that the capillary force on the application portion side is increased, and thus the relay force is relayed via the rear end region 10a. It becomes possible to make it easier for the coating liquid flowing into the core 10 to flow toward the coating unit 8 side.

  The cover 11 is also formed on the surface of the relay core 10 protruding into the storage chamber 3, so that the coating liquid stored in the storage chamber 3 is introduced from the rear end region 10 a of the relay core 10 to the inside. It flows in and can be supplied to the application unit 8.

  In the rear end opening 2c of the partition wall extension 2b, as shown in FIG. 1 (b), a part (at least two or more) of the outer periphery of the relay core 10 is inserted. A contact portion 2A is formed. The contact portion 2A serves to position the relay core 10 and prevents the coating liquid from flowing into the partition wall extension portion 2b via the rear end opening 2c. Specifically, the contact portion 2A is configured as a contact piece (projection piece) that contacts the outer wall of the relay core 10 at four positions on the inner wall of the rear end opening 2c at approximately 90 ° intervals. This makes it difficult for the coating liquid in the storage chamber 3 to flow into the partition wall extension 2b (for example, by making a gap of about 0.02 mm so that it does not easily flow into the partition wall extension). ) When there is a large environmental change such as when the temperature rises, the coating liquid in the storage chamber can flow into the gap G ′ from the gaps between the contact pieces formed at four locations. It has become.

  In addition to the projecting piece, the abutting portion 2A can be appropriately modified such that the inner wall of the rear end opening 2c has a polygonal shape or an elliptical shape. In addition to the position of the rear end opening 2c of the partition wall extending portion 2b, the position where the contact portion is formed is a position that slightly enters the partition wall extending portion 2b (it may be on the rear end opening side). May be preferable). Or you may form such a contact part also in the part of the through-hole 2a of the partition 2 into which the relay core 10 is penetrated.

  In the reservoir chamber 4 described above, as shown in the figure, it is preferable to dispose a liquid absorber 12 through which the relay core 10 covered with the cover 11 can be inserted and impregnated with the coating liquid H. Such a liquid absorber 12 is made of a porous material (cotton or the like) such as a fiber material. By disposing such a liquid absorber 12, the gap G ′ is passed through the gap G. Thus, it is possible to hold the inflowing coating liquid, and a liquid rich state is prevented on the application unit side. In addition, since the outer peripheral surface of the relay core 10 that contacts the liquid absorber 12 is covered with the cover 11, the liquid flowing through the relay core 10 is not absorbed by the liquid absorber 12, At the time of liquid application, the application part side is not in a liquid poor state. Such a liquid absorber 12 may be configured not to be provided in the reservoir chamber 4 as in an embodiment described later.

  According to the eyeliner having the above-described configuration, the coating liquid H accommodated in the storage chamber 3 includes the through hole 2a formed in the partition wall 2 and the gap G between the partition wall extending portion 2b and the relay core 10. The gas-liquid exchange action is performed via the ′, and flows into the relay core from the rear end region (portion where the cover is not covered) 10a protruding from the partition extending portion 2b and moves to the application unit 8 side. To do. In this case, the coating liquid H can come into contact with the rear end region 10a of the relay core 10 by changing the posture, and the coating liquid H that has come into contact with the rear end region immediately moves to the application unit 8 side. Then, it is used (applied) in the application unit 8. Further, since only the rear end region of the relay core 10 is exposed (the cover 11 is not covered), even if there is a change in posture or a temperature rise, the outer peripheral surface of the relay core 10 protruding from the partition wall extension 2b. The amount of the coating liquid flowing into the inside can be restricted, and the liquid rich state on the coating unit 8 side can be effectively prevented.

  In addition, since the partition wall extending portion 2b protrudes into the storage chamber 3, the partition wall extending portion 2b causes the coating liquid to flow into the reservoir chamber 4 even when the posture is changed and the coating portion 8 faces downward. There is nothing, and the application part 8 does not become a liquid rich state. Further, even if the temperature rises (internal pressure rise) occurs in a state where the body 1 is turned sideways or the like, and the coating liquid flows into the partition wall extension 2b, the cover 11 is formed on the surface of the relay core 10. Since it is covered, the coating liquid does not enter the relay core 10, and as a result, the coating unit 8 does not become liquid rich. In this case, it is conceivable that the coating liquid flows into the partition wall extending portion 2b and further flows into the reservoir chamber 4 through the through hole 2a of the partition wall 2 described above. Since the body 12 is disposed and the applied coating liquid H is absorbed, the coating unit 8 does not become liquid-rich.

In addition, as described above, the contact end 2A is formed at the opening end 2c of the partition wall extension 2b, so that the coating liquid does not easily flow into the inside (by surface tension in the vicinity of the opening end 2c). Therefore, it is possible to prevent the coating liquid from flowing out toward the reservoir chamber 4 as much as possible.
That is, even if the temperature rises and the internal pressure increases, or even if the coating liquid comes into contact with the opening end of the partition wall extension portion due to a change in posture, the coating is applied from the gap between the partition wall extension portion 2b and the relay core 10. Since it is difficult for the liquid to flow into the partition wall extending portion 2b, it is possible to prevent the liquid rich state on the application unit 8 side and to prevent wasteful consumption of the coating solution.

  Further, even when the liquid absorber 12 is disposed in the reservoir chamber 4, as described above, the outer peripheral surface of the relay core 10 is covered with the cover 11, and thus flows through the relay core 10. The application liquid is not absorbed by the liquid absorber 12, and the application unit 8 side is not in a liquid poor state during application. That is, the liquid absorber 12 only needs to absorb the coating liquid flowing out from the through hole 2 a of the partition wall 2 and prevent the coating unit 8 from becoming liquid-rich, so that the capillary tube is related to the relay core 10. There is no need to strictly manage force.

  Next, another embodiment of the present invention will be described. In the embodiment described below, the same components as those in the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted.

FIG. 2 is a diagram showing a second embodiment of the present invention.
In this embodiment, a region (notch portion 12 a) that does not cover the cover 11 is formed on the outer peripheral surface of the relay core 10 that penetrates the inside of the liquid absorber 12 disposed in the reservoir chamber 4. That is, the outer peripheral surface of the relay core 10 and the liquid absorber 12 are in partial contact with each other by the notch 12a.

  In such a configuration, when a large amount of coating liquid flows into the relay core 10 due to a temperature rise or the like, the coating liquid is absorbed by the liquid absorber 12 through a portion that does not cover the cover 11. Therefore, the liquid rich state on the application unit 8 side can be more effectively suppressed. In such a configuration, it is possible to increase the area that can contact the coating liquid H in the rear end region of the relay core 10.

FIG. 3 is a diagram showing a third embodiment of the present invention.
As described above, the cover 11 that covers the outer periphery of the relay core 10 is configured so that the coating liquid can flow into the relay core in the storage chamber 3 and is applied to the partition wall extension 2b. Even if the liquid flows in, it is sufficient that it does not flow into the relay core 10.

  For this reason, the cover 11 is at least within the range from the region where the partition wall 2 serving as the boundary with the reservoir chamber 4 is disposed to the contact portion 2A formed in the partition wall extension 2b. It only has to be formed. That is, if the cover 11 is covered in such a range, even if the coating liquid enters the partition wall extension portion 2b, it does not flow into the relay core 10, so that the liquid rich state on the coating portion 8 side is achieved. It becomes possible to suppress effectively. In addition, although it is preferable that the cover 11 is coat | covered by the outer peripheral surface of the relay core 10 in the partition extension part 2b, the notch part etc. may be partially formed.

FIG. 4 is a diagram showing a fourth embodiment of the present invention.
As described above, since the contact portion 2A is formed in the partition wall extension portion 2b, it is difficult for the coating liquid to flow into the partition wall extension portion 2b. As a result, the through hole 2a formed in the partition wall 2 is obtained. Therefore, the liquid absorber may not be provided in the reservoir chamber 4 because the application liquid is prevented from flowing into the reservoir chamber 4 from the inside.

Thus, the manufacturing cost can be reduced by disposing the liquid absorber in the reservoir chamber 4.
In the case where the liquid absorber 12 is not disposed in the reservoir chamber 4, contact portions that contact two or more locations with respect to the outer periphery of the inserted relay core 10 are formed in the through hole 2 a of the partition wall 2. It is preferable to keep it.

  That is, by forming a contact portion similar to the above-described contact portion 2A in the through hole 2a portion of the partition wall 2, the reservoir chamber 4 is removed from the gap between the through hole 2a of the partition wall 2 and the relay core 10. Since the coating liquid does not easily enter the interior and the internal pressure of the partition wall 2 increases, the coating liquid remains in the partition wall even if the temperature rises (internal pressure rise) in a state of posture change such as when the body 1 is turned sideways. It can be made more difficult to enter the partition wall extension from the opening end of the extension 2b, and the coating liquid is not consumed wastefully.

5A and 5B are views showing a fifth embodiment of the present invention, in which FIG. 5A is a diagram showing an overall configuration, and FIG. 5B is a cross-sectional view taken along the line CC in FIG.
In this embodiment, a second partition wall 30 is formed in the reservoir chamber 4, and a through hole 30 a through which the relay core 10 is inserted is formed at the center of the partition wall 30. In this case, a contact portion 30A similar to the above-described contact portion 2A is formed in the through hole 30a, so that the coating liquid flowing out from the through hole 2a of the partition wall 2 is between the partition wall 2 and the partition wall 30. However, the liquid on the application part side is not required to be provided in the reservoir chamber 4 as in the above-described fourth embodiment. A rich state can be prevented. Of course, a similar contact portion may be formed in the through hole 2 a of the partition wall 2, or a liquid absorber may be disposed in the reservoir chamber 4.

FIG. 6 is a diagram showing a sixth embodiment of the present invention.
In this embodiment, the initial storage amount of the coating liquid H stored in the storage chamber 3 is set to a relay core projecting from the partition wall extending portion 2b in a state where the main body 1 is placed on the horizontal plane P (the relay core is exposed). Is set to a position not in contact with the end region 10a).

  In such a configuration, a large amount of the application liquid H stored in the storage chamber 3 is applied via the relay core 10 even when the main body 1 is placed in a horizontal state or the application unit 8 is positioned downward due to a change in posture. And the amount of the liquid flowing into the gap between the partition wall extending portion 2b and the relay core 10 is reduced, so that the liquid rich state on the application portion 8 side can be effectively prevented and the application liquid It is possible to suppress unnecessary consumption.

FIG. 7 is a diagram showing a seventh embodiment of the present invention.
In this embodiment, the initial storage amount of the coating liquid H stored in the storage chamber 3 is the end surface of the partition wall extending portion 2b with the main body 1 placed on the horizontal surface P so that the coating portion 8 faces upward. The position is set so as not to touch.

  In such a configuration, in a state in which the main body 1 is placed with the application portion 8 facing upward, the application liquid stored in the storage chamber 3 is between the partition wall extension portion 2 b and the relay core 10. The liquid does not flow into the gap, and the liquid rich state on the application unit 8 side can be surely prevented, and wasteful consumption of liquid can be suppressed. Furthermore, in the state shown in FIG. 7, even if the temperature suddenly rises or the posture is changed from that state, the coating liquid does not flow into the gap between the partition wall extending portion 2b and the relay core 10, or Since it is difficult to flow in, the liquid rich state on the application unit 8 side can be more effectively prevented.

FIG. 8 is a diagram showing an eighth embodiment of the present invention.
In this embodiment, the liquid absorber 12 disposed in the reservoir chamber 4 is configured such that the porosity on the storage chamber 3 side is low and the porosity of the application unit 8 is high. Specifically, the liquid absorber 12 made of a single material is fitted into a holder 2D formed integrally with the partition wall 2, and a small diameter holding portion 2f and a large diameter holding portion 2g are formed on the holder 2D. Thus, the porosity of the liquid absorber 12 is changed with a simple configuration. That is, the compressive force is strong in the small-diameter holding portion 2f on the storage chamber side, and the porosity of the liquid absorber 12 is low (region indicated by Y), and the compressive force is weak in the large-diameter holding portion 2g on the application portion side. The porosity of the liquid absorber 12 is increased (region indicated by the symbol X).

  In such a configuration, even when the coating liquid flows into the liquid absorber 12 through the through-hole 2a of the partition wall 2, the coating liquid is held on the storage chamber 3 side where the porosity is set low, In the liquid absorber 12, a seal with the coating liquid is formed on the storage chamber side. For this reason, the inflow of the coating liquid from the storage chamber 3 side can be suppressed, and wasteful consumption of the coating liquid can be more effectively suppressed.

As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, A various deformation | transformation is possible.
In the above-described embodiment, the eyeliner that is a cosmetic tool is illustrated as an example of the liquid supply device. However, other devices that store and apply various liquids, such as writing tools, stamps, shoe cleaners, and hair dyes. It is possible to apply to. In this case, the application part connected to the relay core, the shape of the main body 1 and the amount of liquid accommodated can be appropriately modified according to the intended use.

  Moreover, about the cover 11 coat | covered with the relay core 10 in embodiment mentioned above, although it is preferable to coat | cover all the axial directions along the outer peripheral surface of the relay core 10, the notch part is partially formed. May be. Further, the cover 11 may be configured as a member into which the relay core 10 can be inserted, and this may be integrated with the partition wall 2, and the partition wall extension portion 2 b may be configured separately from the partition wall 2. Further, the gap G ′ defined by the partition wall extending portion 2 b may not have the same shape as the gap G of the partition wall 2.

In the above-described embodiment, the example in which the liquid is previously stored in the main body 1 has been described. However, it may be configured as a simple container that does not store the liquid. That is, the user who purchased the container may be configured as a container in which various liquids are stored in the storage chamber 3 and applied by the application unit 8 according to the usage mode. With such a configuration, the operational effects obtained in the above-described embodiments can be obtained, and the storage chamber 3 can be easily filled with the liquid simply by removing the tail plug 5.
