Description

  The present invention is applied to writing instruments such as sign pens and marking pens, cosmetic tools such as eyeliners, stamps, drug application containers, and the like, and stores various liquids such as ink, skin lotion, perfume, and medicine in their raw state. And an applicator that can be applied.

  2. Description of the Related Art Conventionally, applicators are known that store liquids such as ink and skin lotion in a state where they are absorbed by an occlusion body such as batting, but can be stored in a raw state and applied appropriately. For example, Patent Document 1 discloses a raw ink type applicator (writing instrument). In this writing instrument, a through hole through which a relay core is inserted is formed in a partition wall that divides a reservoir chamber and an ink storage chamber, and ink is applied between the inner wall of the through hole and the relay core by capillary force. A predetermined gap is formed so as to be held, and gas-liquid exchange is performed in this portion.

  The ink stored in the ink storage chamber is gas-liquid exchanged in the gap portion between the inner wall of the through hole and the relay core (so that air can flow into the ink storage chamber), so that Consumed (written). In this case, when the ink is consumed, the amount of consumed air enters the ink storage chamber through the gap portion. Further, when the internal pressure in the ink storage chamber increases due to a temperature change or the like, the ink is easily pushed out into the reservoir chamber through the through hole. In particular, when the temperature rises, the amount of expansion of the air becomes the amount of ink extrusion as it is, so that the ink is easily pushed out and a large amount of ink flows out into the reservoir chamber, or the applicator side becomes ink rich. When writing, large dots (ink leakage) may occur. For this reason, it is disclosed that the reservoir chamber is provided with a fibrous occlusion body that temporarily holds the extruded ink.

WO2004 / 000575

  In the direct liquid writing instrument as described above, when the internal pressure in the storage chamber for storing ink increases, the ink flows into the reservoir chamber through the gas-liquid exchange part, and the ink that flows in is held by the occlusion body. The application body is prevented from being in an ink-rich state (ink is ejected from the application body in the form of dots). In addition, the occlusion body provided in the reservoir chamber is in contact with the relay core over 360 °, and since the weaker than the capillary force of the relay core is used, the ink held in the occlusion body is returned to the relay core, It can also be reused on the application body side.

  However, if the writing instrument is used less frequently and used over a long period of time, the occlusion body may become saturated before the ink in the storage chamber is used up. When the ink is saturated in the occlusion body, the surplus ink may be transferred to the application body side through the relay core that penetrates the occlusion body without any gaps, thereby making the application body ink rich. When the coated body is in an ink-rich state, large dots may be produced or ink leakage may occur when writing.

  The present invention provides an applicator provided with an occlusion body that occludes liquid flowing out of a storage chamber in a reservoir chamber, and when the occlusion body is saturated, the application body is liquidized so that it is not returned to the relay member. An object is to provide an applicator that does not become rich.

  In order to achieve the above-described object, an applicator according to the present invention includes a main body, a storage chamber provided in the main body for storing liquid, a liquid provided in the main body and flowing out of the storage chamber. A reservoir chamber that can hold the reservoir chamber, a partition wall that partitions the reservoir chamber and the reservoir chamber, an application body that is provided at an end of the main body and that allows the liquid stored in the reservoir chamber to be applied, and A relay member for passing the liquid stored in the storage chamber through the partition wall to the application body side, and a gas-liquid exchange section formed on the partition wall and performing gas-liquid exchange between the liquid stored in the storage chamber; An occlusion body that is provided in the reservoir chamber in a non-contact state with the relay member and holds the liquid flowing out through the gas-liquid exchanging portion of the partition; and when the liquid flows out of the gas-liquid exchanging portion into the reservoir chamber, A derivative that induces liquid into the occlusion body; Characterized in that it has a.

  In the applicator configured as described above, the storage chamber in which the liquid is stored and the reservoir chamber capable of holding the liquid flowing out of the storage chamber are partitioned by the partition wall, and the liquid stored in the storage chamber has the partition wall. It is transferred to the application body side through the relay member that passes. The reservoir chamber is provided with an occlusion body that is not in contact with the relay member, and the liquid flowing out from the storage chamber side through the gas-liquid exchange section is transferred to and held by the occlusion body via the derivative. In this case, even if the occlusion body is saturated before the liquid in the storage chamber is used up, the occlusion body is not in contact with the relay member, so that the excess liquid is prevented from flowing out to the relay member. It is prevented that the body side is in a liquid rich state. Further, since the occlusion body is not in contact with the relay member, the liquid occluded in that portion does not move to the relay member side, and the application body side is prevented from becoming a liquid rich state.

  According to the present invention, in an applicator provided with an occlusion body that occludes liquid flowing out of the reservoir chamber in the reservoir chamber, the occlusion body is not returned to the relay member when the occlusion body is saturated. It is possible to prevent the liquid from being brought into a liquid rich state.

  Hereinafter, embodiments of an applicator according to the present invention will be described with reference to the drawings. The applicator described in the following embodiments is configured as a cosmetic applied to an eyeliner.

FIG. 1 is a longitudinal sectional view showing a configuration example of an applicator according to the present invention. First, the basic configuration of the present invention will be described with reference to this figure.
The applicator 1 according to the present invention includes a cylindrical shaft (main body) 3 having a hollow portion. The main body 3 includes a storage chamber 5 in which the liquid 100 is stored, and a reservoir chamber 6 that can hold the liquid 100 flowing out of the storage chamber 5. The storage chamber 5 and the reservoir chamber 6 have a partition wall. 7 is divided. In addition, a cap 8 for protecting an applied body, which will be described later, is detachably press-fitted into the holder portion 3a of the main body 3 at the front end side of the main body 3, and a cap-shaped tail plug 9 is provided at the rear end side. It is installed.

  The main body 3 may have a circular cross section or a non-circular shape (such as a polygonal shape). Further, the tail plug 9 may be press-fitted and fixed to the main body 3 or may be configured to be detachable. From this portion, the main body 3 is filled with liquid. And has a function of sealing. In addition, as long as the liquid is filled from the front end side, a configuration in which the tail plug 9 is not provided may be employed.

On the distal end side of the main body 3, a holder portion 3a having a diameter gradually reduced toward the distal end and having an opening 3b at the distal end is formed, and an application body (brush) 10 is attached to this portion. A fibrous holding body 10a for holding a liquid transferred via a relay member described later is provided inside the application body 10, and the liquid filled in the holding body 10a soaks into the application body 10. It is configured as follows. The holder portion 3a is formed with an atmosphere communication hole 3c communicating with the outside air, and the atmosphere communication hole 3c communicates with the reservoir chamber 6 via the inside of the holder portion 3a.
The holder portion 3 a may be formed integrally with the main body 3, or may be configured as a separate member from the main body 3, holding the application body 10 on this, and integrated with the main body 3. Further, communication with the outside air may be performed through the opening 3b.

  A through hole 7a is formed in the central portion of the partition wall 7, and an elongated and circular cross-sectional relay member 20 is inserted into the through hole 7a. The relay member 20 of the present embodiment is inserted so as to have a gap G between the inner surface of the through hole 7a and the outer surface thereof, and the distal end side is connected to the application body 10 (holding body 10a), The rear end side protrudes into the storage chamber 5.

The gap G is formed to such an extent that the liquid can be held by capillary force, and constitutes a gas-liquid exchange part with the storage chamber 5 in which the liquid is accommodated. That is, the liquid held in the gap G moves to the relay member 20 when the liquid is consumed on the application body 10 side, and when the liquid in the gap G is consumed, air flows into the storage chamber 5. Then, the gap G is again filled with the liquid. For this reason, the gap G has a function (gas-liquid exchange function; hereinafter, also referred to as a gas-liquid exchange part G) that causes the consumed air to flow into the storage chamber 5 when the liquid is consumed on the application body side.
In this case, the gap G formed between the outer surface of the relay member 20 and the inner surface of the through-hole 7a may be formed to such an extent that the liquid can be held by capillary force, although it depends on the viscosity of the liquid. The gap G is formed by a configuration in which gas-liquid exchange can be performed by contacting two or more locations with respect to the relay member 20, for example, the cross section of the through hole 7a is polygonal or elliptical (noncircular cross section). The relay member 20 may be formed by inserting a circular relay member. With such a configuration, the relay member 20 can be easily positioned. Alternatively, the relay member 20 may be inserted into the circular through hole, and one or more slits may be formed in the outer surface of the relay member 20 along the axial direction, or may extend radially at the edge of the through hole. Alternatively, one or more slits may be formed, or one or more protrusions may be formed on the inner surface of the through hole so as to contact the outer surface of the relay member 20.

  The gas-liquid exchange part may be formed in any part of the partition wall 7. For example, the relay member 20 may be fitted into the partition wall 7 without a gap, and a through hole may be formed in the other part so that air can move to the storage chamber 5 side. A gap may be formed between the inner surface of the main body 3 (see FIG. 7). That is, as long as air enters the reservoir chamber from the reservoir chamber and the liquid can be transferred to the application body side through the relay member 20, the configuration of the gas-liquid exchange unit can be appropriately modified.

  The relay member 20 is formed as a porous rod-like member by converging and compressing a large number of fibers parallel to the axial direction, and the liquid is applied along the outer surface and by an internal capillary force. 10 (holding body 10a) side. In this case, the relay member 20 only needs to have a structure that transfers the liquid stored in the storage chamber 5 with capillary force toward the application body with high sensitivity, and the porosity of the relay member 20 is that of the liquid stored in the storage chamber. It is appropriately selected depending on the viscosity. For example, it is preferable to use a liquid having a low porosity if the liquid has a low viscosity, and to use a liquid having a high porosity if the liquid has a high viscosity.

  The relay member 20 is not limited to a fiber member as long as it functions to transfer the liquid stored in the storage chamber to the application body 10. For example, it may be a molded product such as plastic, and may have a structure that can hold liquid by capillary force along the axial direction.

  The holding body 10a disposed inside the application body 10 may be integrated with the relay member 20, or, like the relay member, formed by converging and compressing a plurality of fibers. May be abutted against the front end surface of the relay member. That is, the holder itself also has a function of causing capillary action between the individual fibers and moving the liquid in the longitudinal direction so that the liquid is immersed in the application body 10. In addition, although the capillary force of the holding body 10a is set larger than the capillary force of the relay member 20, the liquid can easily move toward the application body 10, but the capillary forces of both may be set to be the same. .

  As shown in the figure, an occlusion body 30 that surrounds the relay member 20 and is in contact with the outer peripheral surface and occludes liquid is disposed in the reservoir chamber 6. Such an occlusion body 30 can be composed of, for example, a porous material (cotton or the like) such as a fiber material, and when the liquid flows out from the gas-liquid exchange part (gap G), the liquid is Any device having a holding function may be used. For this reason, the occlusion body 30 may be configured by, for example, a bellows-shaped member (molded product such as plastic) that sequentially holds the liquid by a capillary force along the axial direction in addition to the porous material described above. .

  The occlusion body 30 is installed in the reservoir chamber 6 in a non-contact state with respect to the relay member 20. That is, the relationship between the occlusion body 30 and the relay member 20 is configured such that the liquid held in the occlusion body 30 does not return to the relay member 20. In the configuration shown in the figure, a through hole 30a is formed in the occlusion body 30 in the axial direction, and the relay member 20 is inserted into the through hole 30a in a non-contact state over 360 °. It is configured to be in a non-contact state. That is, a gap S is formed around the relay member 20, and the liquid held in the occlusion body 30 cannot move to the relay member 20.

“Making the relay member 20 and the occlusion body 30 in a non-contact state” means that the liquid cannot move from the occlusion body to the relay member. A layer in which the liquid cannot move along the axial direction on the outer surface of the member 20 and / or the inner surface of the occlusion body 30 (formed by coating a resin or wax or baking the surface). May be formed.
By arranging such an occlusion body 30 in the reservoir chamber 6, even if the liquid leaks through the gas-liquid exchange part, the liquid is retained and the application body 10 is brought into a liquid rich state. Can be prevented.

  The occlusion body 30 only needs to be held in the reservoir chamber 6 in a non-contact state with the relay member 20. As shown in the figure, if a gap S is formed around the relay member 20 to make the occlusion body 30 in a non-contact state, a cylindrical shape that is press-fitted into the inner surface of the main body 3 at the lower end of the partition wall 7. The holder 7b is integrally formed, and the occlusion body 30 is disposed in this portion, so that it can be held in the reservoir chamber.

  If the gas-liquid exchange part (gap G) described above is in a normal use state, the liquid in the storage chamber 5 is held by capillary force, but the internal pressure of the storage chamber 5 increases, for example, the temperature increases. Then, the liquid flows out to the reservoir chamber side. A derivative 70 for guiding the liquid flowing out from the gas-liquid exchange part to the storage body 30 is disposed between the partition wall 7 and the storage body 30 so that the liquid flowing out can be held by the storage body 30. ing.

  The derivative 70 may be configured to be able to guide the liquid flowing out from the gas-liquid exchange unit to the occlusion body 30, and may be configured to form a liquid flow path so that the liquid can be transferred into the occlusion body 30. For example, molded products such as resin, slits formed in the partition walls 7 and the holders 7b, porous materials that can hold and transfer liquid by capillary force (for example, cotton material entangled with fibers, or suck liquid by capillary force) It is possible to configure the paper material such as a possible Japanese paper). In this case, the derivative 70 can increase the volume of the occlusion body 30 (increase the liquid occlusion amount) in the reservoir chamber by shortening the axial length, and the type of liquid to be stored, The size of the derivative 70 can be set as appropriate depending on the application. For example, the volume of the occlusion body 30 can be increased by making the derivative 70 a thin paper material.

Further, in the reservoir chamber 6, it is preferable to form a bottom portion 61 between the main body 3 and an annular liquid outflow prevention wall 60 surrounding the relay member 20. Such a liquid outflow prevention wall 60 is disposed between the occlusion body 30 and the application body 10, and when the occlusion body 30 on the application body side becomes saturated and can no longer hold liquid, the liquid outflow prevention wall 60 is retained. It has a function of storing liquid that cannot be produced.
In such a configuration, the occlusion body 30 described above is preferably disposed so as to be in contact with the inner surface of the main body 3 (the application body side of the occlusion body 30 may be in contact with the inner surface of the main body 3). Usually, since the liquid has a property of being transmitted through the contacted portion, surplus liquid can be reliably guided to the bottom 61 by keeping the occlusion body 30 in contact with the inner surface of the main body, and the liquid outflow The prevention wall 60 can reliably prevent the transfer to the relay member 20 (do not make the application body side rich in liquid).

Next, the operation of the applicator described above will be described.
As described above, by arranging the occlusion body 30 in the reservoir chamber 6, even if the liquid is pushed out from the storage chamber side through the gas-liquid exchange portion due to a temperature rise or the like, the liquid is stored via the derivative 70. The application body 10 side is not brought into a liquid rich state. In this case, the derivative 70 may be configured to hold a certain amount of liquid and guide the held liquid to the occlusion body 30, or the liquid flowing out from the gas-liquid exchange unit G may be directly passed to the occlusion body 30. The structure which guides toward may be sufficient. And when such an applicator is used over a long period of time (frequently used), the occlusion body 30 may become saturated before the liquid in the storage chamber is used up. However, even if the occlusion body 30 is saturated, the liquid is suppressed from flowing out to the relay member 20, and the application body 10 side is prevented from being in a liquid-rich state. Even if the occlusion body 30 is saturated and the liquid cannot be held, the liquid can be prevented from flowing out to the relay member 20 by providing the liquid outflow prevention wall 60.

  In the configuration described above, it is possible to set the liquid so that no liquid is excessive on the storage body side by considering the amount of liquid that can be held in the storage body 30 and the amount of liquid stored in the storage chamber 5. is there. Moreover, the relationship between the capillary force of the gas-liquid exchange part (gap) G, the capillary force of the derivative 70, and the capillary force of the occlusion body 30 can be set as follows.

The capillary force of the derivative 70 is set to be greater than or equal to the capillary force of the gas-liquid exchange part G, and the capillary force of the occlusion body 30 is set to be weaker than the capillary force of the derivative 70.
If such a relationship is set, the liquid can easily move from the gas-liquid exchange part G to the derivative 70 at room temperature, so that the derivative 70 can be used as a liquid reservoir. In this case, when the derivative 70 is saturated and the liquid flows out from the gas-liquid exchange part, the liquid is held by the occlusion body 30, so that the liquid is saturated by the occlusion body 30 as much as possible. It becomes possible.

The capillary force of the derivative 70 may be set to be weaker than the capillary force of the gas-liquid exchange unit G, and the capillary force of the occlusion body 30 may be set to be stronger than the capillary force of the derivative 70.
If the relationship is set as described above, since the derivative 70 does not suck the liquid from the gas-liquid exchange unit at normal temperature, the liquid transfer by the relay member 20 is not hindered and the smoothness of the application body 10 can be achieved. Liquid application is possible. Further, when the temperature rises and the internal pressure in the storage chamber increases, the liquid flows out to the derivative 70, and the liquid flowing out here moves to the occlusion body 30 having a stronger capillary force than the derivative 70. That is, the occlusion body 30 functions only when the internal pressure in the storage chamber increases (when the temperature expands), so that it is possible to prevent liquid from flowing unnecessarily to the occlusion body side.

Next, various embodiments that embody the basic configuration shown in FIG. 1 will be described.
Drawing 2 is a figure showing a 1st embodiment of an applicator.
As described above, the occlusion body 30 that holds the liquid flowing out from the gas-liquid exchange part G is made of a porous material in which fibers are entangled, and is a derivative disposed between the partition wall 7 and the occlusion body 30. 71 is comprised with the molded article.

  Specifically, the derivative 71 is formed of a bellows-shaped member (molded product such as plastic) that sequentially holds the liquid by the capillary force along the axial direction, and the occlusion body 30 so that the liquid can move directly. Is touching. In this case, the entire structure of the derivative 71 may be in surface contact with the occlusion body 30, or a part (for example, an outer diameter portion) of the derivative 71 may be in contact with the occlusion body 30.

  Such a molded product (occlusion body composed of a bellows-shaped member) is generally employed in a writing instrument such as a fountain pen, but has a smaller outer diameter and an axial direction as compared with such a known molded product. Since it is possible to use one having a shorter length, dimensional management and the like are facilitated. In addition, when the derivative 71 is formed of a molded product, it can be integrally formed with the partition wall 7, and by incorporating the partition wall 7 and the derivative 71 integrally, the incorporation into the main body 3 can be improved.

Moreover, the holder part 3a of this embodiment is shape | molded separately from the main body 3, and such a separate holder part 3a is integrally fixed with respect to the main body 3, and the application body 10 is attached. An air communication hole 3c is formed along the axial direction outside the portion to be held in the radial direction. And the rib 3d is formed in the storage chamber side of the holder part 3a, and the said occlusion body 30 is hold | maintained by this rib 3d so that it may be in a non-contact state with respect to the relay member 20. FIG.
The occlusion body 30 may be provided with a gap S1 between the inner surface of the main body 3, and by forming such a gap S1, the sensitivity of gas-liquid exchange can be improved. Further, a liquid outflow prevention wall 60 as shown in FIG. 1 may be disposed in the reservoir chamber 6.

  The derivative 71 is interposed between the occlusion body 30 and the partition wall 7, has a function of holding the liquid flowing out from the gas-liquid exchange part G, and further holds the liquid flowing on the surface of the relay member 20. It may have a function. Since the derivative 71 can be formed of a molded article such as a resin, even if an additive such as a preservative is contained in the liquid, the additive is not left inside like a fibrous material. 100% can be supplied to the coated body side.

  In the present embodiment, an air flow path is secured between the occlusion body 30 and the inner surface of the main body 3, and between the derivative 71 and the inner surface of the main body 3, and the gap G of the partition wall 7 Since it is in contact with the molded product, the air introduced from the outside can enter the storage chamber 5 side without resistance. Therefore, even when a liquid having a somewhat high viscosity is used, the application sensitivity can be improved without bringing the application body side into a liquid-rich state.

FIG. 3 is a diagram showing a second embodiment of the applicator.
In the present embodiment, as in the configuration shown in FIG. 2, the derivative 71 that induces the liquid flowing from the gas-liquid exchange unit is configured as a molded product together with the partition wall 7, and further protrudes into the storage chamber 5. A storage chamber occlusion body (a bellows-shaped member) 72 formed integrally with the partition wall 7 is provided. The storage chamber occlusion body 72 is in contact with the relay member 20 that terminates in the storage chamber, and the capillary force is set to be equal to or less than the capillary force of the gas-liquid exchange unit G.

  In such a configuration, the storage chamber occlusion body 72 installed in the storage chamber can hold the liquid, and the liquid that has become saturated here is transferred to the derivative 71 via the gas-liquid exchange section G. Will come to be. That is, by arranging the storage chamber occlusion body 72 in the storage chamber 5, the resistance at the time of liquid movement to the gas-liquid exchange section G and the liquid movement from the gas-liquid exchange section G to the derivative 71 Is reduced, and the sensitivity of gas-liquid exchange is improved. In addition, since the liquid can be supplied to the relay member side through the storage chamber storage body 72 that is initially saturated, the derivative 71 is not saturated at an early stage, and stable coating is performed over a long period of time. It becomes possible. Further, when the gas-liquid exchange part G is configured with gaps having a polygonal cross section (a gas-liquid exchange part is constituted by a plurality of gaps), the liquid can be held in all the gaps by capillary force (siphon phenomenon is It does not occur), it is possible to obtain a stable gas-liquid exchange action.

  In addition, although the storage chamber occlusion body 72 is configured by a bellows-shaped member integrally formed with the partition wall 7, it may be configured by a porous fibrous member. In such a configuration, it is possible to form a cylindrical holder on the storage chamber side of the partition wall 7 and press-fit and hold a fibrous member occlusion body in the holder.

FIGS. 4A and 4B are diagrams showing a third embodiment of the applicator, where FIG. 4A is a longitudinal sectional view, and FIG. 4B is a sectional view taken along line AA.
The derivative 73 of this embodiment is formed of a molded product integrally formed with the partition wall 7 and includes four slits 73a extending in the longitudinal direction at substantially 90 ° intervals. The liquid can be held by capillary force. Note that the number of slits, capillary force, and axial length (liquid storage amount) can be appropriately modified.

  In such a configuration, by setting the capillary force of each slit 73a stronger than the capillary force of the gas-liquid exchange part G of the partition wall 7, each slit can function as a liquid reservoir. Alternatively, if the capillary force of each slit 73a is set to be weaker than the capillary force of the gas-liquid exchange part G, the liquid flows to the occlusion body 30 via the slit 73a in a normal use state where there is no temperature change or the like. Therefore, stable liquid supply to the application body 10 is realized, and the occlusion body 30 is prevented from being saturated early.

  In addition, about the slit used as the derivative integrally formed with the partition wall 7, a shape (radiation groove) radially extending in the radial direction from the through hole 7 a may be formed on the reservoir chamber side of the partition wall 7. With such a configuration, the derivative can be thinned in the axial direction, and the amount of liquid stored in the occlusion body 30 can be increased.

FIG. 5 is a diagram showing a fourth embodiment of the applicator.
In the above-described embodiment, the derivative is disposed between the partition wall 7 and the occlusion body 30, but the derivative may be disposed on the application body side with respect to the occlusion body 30 as shown in FIG. The occlusion body 30 of this embodiment is held so as to abut against the partition wall 7, and the gap S by the through hole 30a has a larger diameter than the gas-liquid exchange part G. That is, the liquid flowing out from the gas-liquid exchange part G is configured to flow out into the derivative 75 through the gap S as it is.

The derivative 75 is made of a porous fiber material so as to contact the relay member 20 and the occlusion body 30 so that the liquid held in the derivative 75 can be transferred to the occlusion body 30 side. It is configured. For this reason, the capillary force of the occlusion body 30 is set to be stronger than the capillary force of the derivative 75. In such a configuration, since the liquid flowing out from the gas-liquid exchange part G passes through the through hole 30a of the occlusion body 30, a coating (outer skin) is formed on the inner surface of the through hole 30a so that the liquid does not enter. It is preferable to keep it. Since the derivative 75 also has a function of holding the liquid, the outer surface of the relay member 20 and the inner surface of the through-hole of the derivative 75 are coated so that the liquid does not move between the relay member 20 ( It is preferable to form a skin).
As described above, the position where the derivative is disposed can be appropriately modified.

FIG. 6 is a view showing a fifth embodiment of the applicator.
In this embodiment, the relay member is divided in the axial direction in the derivative 75 made of a porous fiber material, and the relay members 20A and 20B divided on the same axis are disposed. The derivative 75 of the present embodiment is composed of a porous fiber material and has a function of holding the liquid flowing out from the gas-liquid exchange part G, and its capillary force is set stronger than that of the gas-liquid exchange part G. , Keep the liquid saturated. By dividing the relay member in the derivative 75, it is possible to prevent a large amount of liquid from flowing through the relay member. That is, in the applicator that contains a low-viscosity liquid, it is easy for the liquid to flow through the relay member of the above-described embodiment, and the applicator side tends to be in a liquid-rich state, but by dividing the relay member inside the derivative 75, The derivative 75 functions as a liquid reservoir, and the liquid in that portion is supplied from the contact portion of the relay member 20A to the application body side. In this case, when a liquid further flows into the derivative 75, the excess liquid flows out to the occlusion body 30 and does not return to the relay member 20A.

  In the above-described structure, it is possible to effectively limit the amount of liquid supplied to the application body 10, but either one or both of the both end surfaces 20a and 20b of the relay member 20B are baked. By processing into a closed state, it is possible to further limit the amount of liquid flowing into the relay member 20B.

FIG. 7 is a view showing a sixth embodiment of the applicator.
In each embodiment mentioned above, although the gas-liquid exchange part was comprised by the clearance gap G between the inner surface of the through-hole 7a of the partition 7, and the outer surface of the relay member 20 penetrated here, a gas-liquid exchange part is provided. The position is not particularly limited. As in this embodiment, a slit 7c is formed at the peripheral edge of the partition wall 7, and a gap G is formed between the slit 7c and the inner surface of the main body 3 to form a gas-liquid exchange unit. You may make it fit with respect to the partition 7 without a gap.

  In this embodiment, the gas-liquid exchange part G is brought into contact with a derivative 75 composed of a porous fiber material installed between the partition wall 7 and the occlusion body 30, and the gas-liquid exchange part is transferred from the storage chamber 5. The liquid flowing out through G is held in the storage body 30 via the derivative 75. The liquid retained in the occlusion body 30 does not return to the relay member 20 due to the gap S.

FIG. 8 is a view showing a seventh embodiment of the applicator.
In this embodiment, in the structure shown in FIG. 7, an annular side wall 7e extending toward the storage chamber is formed at the peripheral end of the partition wall 7, and an axially extending groove (slit) is formed in a part of the outer periphery of the side wall. ) 7f is formed, and a gap G between the slit and the inner surface of the main body is used as a gas-liquid exchange part. That is, the storage chamber side of the partition wall 7 is formed in a cup shape, and an extension portion 7g extending to the storage chamber side is formed in the portion where the through hole 7a is formed, and the relay portion 7g is relayed in the extension portion 7g. The member 20 is fitted with no gap. Further, the relay member 20 slightly protrudes from the end portion of the extension portion 7g, and is configured so that liquid can flow in from the protruding portion. Further, the gas-liquid exchange part (gap G) communicates with the derivative 75, and the occlusion body 30 is disposed in contact with the derivative 75.

  In such a structure, since the gas-liquid exchange part G is always in the state of opening the storage chamber 5 by setting the storage amount of the liquid 100 to be the extension part 7g or less, the liquid in the storage part Tends to flow toward the coated body. That is, since the gas-liquid exchange can be performed without the resistance of the liquid, it is possible to supply the liquid smoothly to the application body side, particularly when a highly viscous liquid is accommodated. If the liquid is highly viscous, the liquid is difficult to enter the gas-liquid exchange part G even if the body is changed in the horizontal direction, and even if it enters, it is occluded by the occlusion body 30 via the derivative 75. Thus, the application member side is not returned to the relay member 20, and the application body side is not brought into the liquid rich state.

  Further, in the structure as described above, if the viscosity of the liquid to be stored is high, a gap is formed between the extension 7g and the relay member 20 so that gas-liquid exchange can be performed also in this part. Also good.
