Description

  The present invention relates to a liquid application container capable of applying a liquid such as a chemical solution contained therein to an object.

Various types of liquid application containers that can apply a liquid such as a chemical liquid, a cleaning liquid, a cosmetic liquid, and an adhesive liquid to an object have been provided. For example, instead of simply applying a liquid, a predetermined amount of liquid is once stored in the liquid reservoir, and then the application surface is pressed against the object to apply the liquid to the object. A liquid application container that can be used is known (see Patent Document 1).
According to this type of liquid application container, it is possible to apply a certain amount of liquid stored in the liquid reservoir without being excessively applied or insufficiently applied.
Utility Model Registration No. 2541327

However, the following problems still remain in the conventional liquid application container.
First, when applying various liquids, a small amount of liquid (for example, a few micrograms of liquid) is applied multiple times according to the application and purpose of application, and evenly in the desired range of the object. It may be preferred to apply to
In such a case, since the amount of liquid is very small, it is difficult to temporarily store only this amount in the liquid reservoir. Therefore, only a very small amount of liquid must be applied from a certain amount of liquid. However, in conventional liquid application containers, the application amount varies easily with each application, depending on the pressure during application (pressure to grip the container, pressure to press the application surface against the object, etc.), inclination of the container, etc. Resulting in. Therefore, it has been very difficult to apply a minute amount of liquid uniformly in a desired range of the object by a plurality of application operations.

  The present invention has been made in consideration of such circumstances, and its purpose is to temporarily store a certain amount of liquid and then apply a small amount of liquid in a plurality of times to reliably apply the object. It is an object of the present invention to provide a liquid application container that can uniformly apply a liquid to a desired range without any unevenness.

In order to achieve the above object, the present invention provides the following means.
A liquid application container according to the present invention is a liquid application container that applies a liquid to an object by pressing an application body that is inserted in and out of a minute hole against the object, and has a squeeze property in an axial direction. A container body that discharges the liquid contained inside when the bottom surface is pushed with a fingertip from the mouth side to the outside, and the container body is housed inside with the bottom surface of the container body exposed. An outer cylinder, a notch groove formed in the outer cylinder and exposing the bottom surface side of the container main body by a certain pushing allowance, and an opening side of the container main body, and the application body is arranged inside In addition, the liquid discharged from the container main body is collected, a liquid reservoir portion having the micro hole formed at the tip thereof, and stored in the liquid reservoir portion, and the application body is biased toward the micro hole. The base end side of the coated body is the inner surface of the liquid reservoir And a coating stopper mechanism having an urging body to block the flow path to the micropores by contacting, in the interior of the container body, when the container body is pushed beyond the press allowance Further, a stopper is provided that contacts the bottom surface and restricts further pressing .

In the liquid application container according to the present invention, first, the bottom surface of the container body housed in the outer cylinder is pushed in with a fingertip, and the liquid housed in the container body is discharged into the liquid reservoir. At this time, since the cutout groove is formed in the outer cylinder, the container body can be pushed by a certain pushing amount by one pushing operation. That is, the amount of pushing can be made as uniform as possible by pushing the container body until the fingertip touches the notch groove. Accordingly, the amount of liquid fed into the liquid reservoir can be made uniform, and a certain amount of liquid can be stored in the liquid reservoir.
By the way, when the liquid is stored in the liquid reservoir, the urging body of the application plug mechanism urges the application body toward the minute hole, and the base end side of the application body is brought into contact with the inner surface of the liquid reservoir. Therefore, the flow path to the micropores is blocked. For this reason, the liquid sent into the liquid reservoir does not flow into the micropores and flow outside.

Next, after the liquid is once stored in the liquid reservoir, the application body is pressed against the object with a force against the urging body while holding the outer cylinder. Accordingly, the application body moves along the axis so as to be immersed in the liquid reservoir. Then, the base end side of the application body is also linked to the inside and moves to the inside of the liquid reservoir, so that the flow path away from the inner surface of the liquid reservoir and toward the minute hole is opened. As a result, the liquid stored in the liquid reservoir can be exuded by a minute amount to the outside through the gap between the minute hole and the application body, and a minute amount of liquid can be applied to the object.
In particular, since the liquid flows to the outside through a slight gap between the micropores and the application body, even if the application body is pressed, the liquid continues to flow out due to the influence of surface tension and the like. Can be suppressed. Therefore, a small amount of liquid can be reliably applied in a plurality of times by a single application operation. As a result, it is possible to suppress variation in the coating amount for each coating operation, and the liquid can be evenly applied to the desired range of the object without unevenness.

  The liquid applicator container according to the present invention is characterized in that, in the liquid applicator container according to the present invention, a bellows portion for extending and contracting the container main body in the axial direction is formed on the outer peripheral surface of the container main body. Is.

  In the liquid application container according to the present invention, the bellows portion is formed on the outer peripheral surface of the container main body. Therefore, when the container main body is pushed in with a fingertip, the bellows portion is in a state of being shrunk by initiative. Therefore, in addition to the effect by the notch groove, the pushing amount of the container body can be made more uniform by forming the bellows part. As a result, a more accurate amount of liquid can be sent into the liquid reservoir each time.

  In the liquid application container according to the present invention, even if the user pushes the container body further beyond the pushing allowance, the bottom surface of the container body comes into contact with the stopper, so that further pushing is restricted. Therefore, a more accurate amount of liquid can be fed into the liquid reservoir.

  According to the liquid application container according to the present invention, after a certain amount of liquid is once stored in the liquid reservoir, a small amount of liquid can be reliably applied in a plurality of times. Therefore, it is possible to apply the liquid evenly over the desired range of the object without unevenness. In particular, when it is desired to reliably apply a predetermined amount of liquid to an object, the liquid application container according to the present invention can be suitably used.

Hereinafter, an embodiment of a liquid application container according to the present invention will be described with reference to FIGS. 1 to 4.
The liquid application container 1 according to the present embodiment applies the liquid W to the object by pressing the application body 2 that is inserted in the minute hole 5b along the axis L so as to be able to protrude and retract, against the object (not shown). It is a container that can. The liquid W may be anything such as a chemical liquid, a cleaning liquid, a cosmetic liquid, or an adhesive liquid, and may be appropriately selected according to the object.

As shown in FIGS. 1 and 2, the liquid application container 1 includes a container main body 3 that stores the liquid W therein, an outer cylinder 4 that stores the container main body 3 therein, and a liquid in which the liquid W is temporarily stored. The reservoir 5 includes an application stopper mechanism 6 for flowing a small amount of liquid W out of the stored liquid W, and a cap 7 that covers when not in use.
FIG. 1 is an external view of the liquid application container 1. 2 is a cross-sectional arrow view AA of the liquid application container 1 shown in FIG.

  The container body 3 is a portion that becomes an inner cylinder, and is formed by a resin material or the like so as to have a squeeze property in the direction of the axis L. Therefore, the container body 3 is configured to discharge the liquid W, which is deformed in the direction of the axis L and accommodated therein when the bottom surface 3a is pushed with a fingertip, from the mouth 3b side. A male screw 3c is formed in a spiral on the outer peripheral surface of the mouth 3b. A bellows portion 3d is formed on the outer peripheral surface of the container main body 3 on the side of the bottom surface 3a to expand and contract the container main body 3 in the axis L direction by a predetermined amount. Thereby, when the container main body 3 is pushed in with a fingertip, the part of the bellows part 3d takes the initiative and shrinks compared with other parts.

  The outer cylinder 4 is, for example, injection-molded with a resin material or the like, and accommodates the container body 3 therein with the bottom surface 3a of the container body 3 exposed. More specifically, the outer cylinder 4 can store the container body 3 on one end side and the liquid reservoir 5 on the other end side with the partition wall 4a interposed therebetween. In the partition wall 4 a, the cylindrical member 4 b extends along the axis L direction by a length substantially equal to the entire length of the container body 3. And the inside of this cylinder member 4b becomes a storage chamber in which the container main body 3 is stored. Moreover, the internal thread 4c by which the above-mentioned external thread 3c is screwed is formed in the internal peripheral surface of the cylinder member 4b near the partition 4a. By screwing the male screw 3c formed in the mouth portion 3b of the container main body 3 to the female screw 4c, the container main body 3 and the outer cylinder 4 can be fixed to each other with the container main body 3 stored in the storage chamber. It has become. A packing 8 that prevents the liquid W from leaking is interposed between the partition wall 4 a of the outer cylinder 4 and the mouth portion 3 b of the container body 3.

Two cutout grooves 10 that expose the bottom surface 3a side of the container main body 3 accommodated therein by a certain pushing allowance H are formed at the tip of the cylindrical member 4b so as to face each other with the axis L interposed therebetween. In the present embodiment, the push allowance H is exemplified as a case where the push allowance H substantially coincides with the expansion / contraction amount (stroke amount) of the bellows portion 3d.
In addition, a hollow projecting member 4d projects along the axis L direction toward the opposite side of the cylindrical member 4b at the center of the partition wall 4a. The projecting member 4d communicates with a storage chamber in which the container body 3 is stored. In addition, a minute opening 4e is formed at substantially the center of the end face of the protruding member 4d. Thereby, the liquid W discharged from the container main body 3 passes through the inside of the protruding member 4d, and then flows from the minute opening 4e to the outside of the outer cylinder 4.

  Further, a first fixed cylinder 4f for fixing the application plug mechanism 6 extends along the axis L direction so as to surround the protruding member 4d around the partition 4a, and the first fixed cylinder 4f A second fixed cylinder 4g for fixing the liquid reservoir 5 extends along the axis L direction so as to surround the periphery. A male screw 4h is formed on the outer peripheral surface of the second fixed cylinder 4g located outside the fixed cylinders 4f and 4g.

The liquid reservoir 5 is, for example, injection-molded with a resin material or the like, and plays a role of storing the liquid W discharged from the container body 3 through the minute opening 4e of the protruding member 4d. The liquid reservoir 5 is fixed in a state where the base end side is inserted between the two fixed cylinders 4f and 4g. That is, the liquid reservoir 5 is fixed to the outer cylinder 4 in a state of being disposed on the mouth 3b side of the container body 3. At this time, on the outer peripheral surface of the liquid reservoir portion 5, a flange portion 5 a that contacts the end portion of the second fixed cylinder 4 g is formed. Thereby, the liquid reservoir 5 is firmly fixed in a stable posture.
The liquid reservoir 5 is formed so that the outer diameter gradually narrows toward the tip, and a micro hole 5b through which the application body 2 is inserted is formed at the approximate center of the tip.

The coating plug mechanism 6 includes an application body 2 and an urging body 11 formed integrally with the application body 2, and is stored in the liquid reservoir 5. The applicator body 2 and the urging member 11 may not be integrally molded, and the applicator plug mechanism 6 may be configured in combination.
The application body 2 is formed in a rod shape from the base end 2a side to the tip end 2b, and is inserted into the minute hole 5b while being movable along the axis L. On the other hand, the base end 2a side of the application body 2 is in a state of expanding and expanding in the radial direction.
The biasing body 11 is a spring formed of, for example, a resin material, one end side is fixed to the base end 2a side of the application body 2, and the other end side is an end surface of the first fixed cylinder 4f via the fixing ring 2c. It is fixed on the top. The urging body 11 constantly urges the application body 2 to project the distal end 2b of the application body 2 from the liquid reservoir 5 to the outside, and the base end 2a side of the application body 2 is liquid. By making contact with the inner surface of the pool portion 5, the flow path to the minute hole 5b is blocked.

The cap 7 is formed of a resin material or the like so as to be smoothly curved toward the tip, and a female screw 7a is formed on the inner peripheral surface of the cap 7 to be screwed onto the male screw 4h. Thus, the cap 7 can be fixed to the outer cylinder 4 by covering the cap 7 when not in use, and screwing the cap 7 and screwing the male screw 4h and the female screw 7a.
In addition, on the inner surface of the front end side of the cap 7, a first storage cylinder 7b into which the front end of the liquid reservoir 5 is inserted when the cap 7 is fixed, and a second storage cylinder 7c into which the front end of the application body 2 is inserted. Is formed in a state extending along the direction of the axis L.

Next, a case where a small amount of liquid W is applied to an object using the liquid application container 1 configured as described above will be described with reference to FIGS. 3 and 4.
FIG. 3 is a view showing a state in which after the cap 7 is removed, the bottom surface 3 a of the container body 3 is pushed in to feed the liquid W into the liquid reservoir 5. FIG. 4 is a diagram showing a state in which a small amount of liquid W is applied from the liquid W stored in the liquid reservoir 5 by pressing the application body 2 against an object (not shown).

First, from the state shown in FIGS. 1 and 2, the cap 7 is twisted to unscrew the male screw 4h and the female screw 7a, and the cap 7 is removed. Next, as shown in FIG. 3, the bottom surface 3a of the container main body 3 accommodated in the outer cylinder 4 is pushed in with a fingertip, and the liquid W accommodated in the container main body 3 is discharged from the mouth part 3b. Then, the liquid W discharged from the mouth 3b passes through the protruding member 4d constituting the outer cylinder 4, and then flows into the liquid reservoir 5 through the minute opening 4e. Thereby, the liquid W can be temporarily stored in the liquid reservoir 5.
In addition, the container body 3 is exposed by a certain pushing allowance H by the notch groove 10 formed in the cylindrical member 4 b of the outer cylinder 4. Therefore, in performing one pushing operation, the pushing amount can be made as uniform as possible by pushing the container body 3 with the fingertip until the notch groove 10 is touched. Accordingly, the amount of the liquid W fed from the container body 3 into the liquid reservoir 5 can be made uniform, and a certain amount of the liquid W can be stored in the liquid reservoir 5.

  In addition, since the bellows portion 3d is formed in the container main body 3, when the container main body 3 is pushed in with a fingertip, the portion of the bellows portion 3d takes the initiative and contracts by a predetermined amount. Therefore, in addition to the above-described effect by the notch groove 10, the amount of pushing of the container body 3 can be made more uniform by forming the bellows portion 3d. As a result, a more accurate amount of liquid W can be fed each time.

  By the way, when the liquid W is stored in the liquid reservoir 5, the biasing body 11 biases the application body 2 toward the minute hole 5 b along the axis L direction, and the base end 2 a of the application body 2. The side is brought into contact with the inner surface of the liquid reservoir 5 to block the flow path to the microhole 5b. Therefore, the liquid W sent into the liquid reservoir 5 does not flow into the minute hole 5b side and flow out to the outside.

  Next, after a certain amount of liquid W is stored in the liquid reservoir 5, as shown in FIG. 4, the tip 2b of the application body 2 is moved toward the object by a force against the urging body 11 while gripping the outer cylinder 4. Press against. As a result, the application body 2 moves along the axis L so as to be immersed in the liquid reservoir 5. Then, since the base end 2a side of the application body 2 is also linked to the inside of the liquid reservoir portion 5, the contact is released away from the inner surface of the liquid reservoir portion 5, and the flow path toward the microhole 5b is reached. Is released. As a result, the liquid W stored in the liquid reservoir 5 can be exuded by a minute amount to the outside through the gap between the minute hole 5b and the application body 2, and a very small amount (for example, several μg) of the object. The liquid W can be applied.

  In particular, since the liquid W flows to the outside through a slight gap between the minute holes 5b and the application body 2, even if the state where the application body 2 is pressed is maintained, the liquid W is affected by the surface tension and the like. It can be suppressed that it continues to flow out. Therefore, a small amount of liquid W can be reliably applied in a plurality of times by a single application operation. As a result, it is possible to suppress variation in the coating amount for each coating operation, and the liquid W can be evenly applied to the desired range of the object without unevenness.

  As described above, according to the liquid application container 1 of the present embodiment, after a certain amount of the liquid W is once stored in the liquid reservoir 5, a small amount of the liquid W is reliably applied in a plurality of times. can do. Therefore, the liquid W can be uniformly applied to the desired range of the object without unevenness.

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

  For example, in the above embodiment, the two notched grooves 10 are formed in the cylindrical member 4b of the outer cylinder 4, but one or three or more may be used. Further, the notch groove 10 may be formed deeper to further secure the push allowance H. Moreover, although the case where only one stage of the bellows portion 3d was formed was described as an example, two or more stages may be formed.

Further, as shown in FIG. 5, a stopper 20 is provided in the container body 3 to contact the bottom surface 3a when the container body 3 is pushed beyond the pushing allowance H and to restrict further pushing. It doesn't matter. For example, the stopper 20 has a cylindrical shape extending along the direction of the axis L, and is fixed to the mouth 3b side. The stopper 20 is formed with a plurality of minute through holes 20a so as not to block the flow of the liquid W. However, the shape of the stopper 20 is not limited to a cylindrical shape, and may be a plate shape extending in the direction of the axis L.
By providing the stopper 20 in this way, even if the user further pushes the container body 3 beyond the pushing allowance H, the bottom surface 3a of the container body 3 contacts the stopper 20, so that further pushing is restricted. Is done. Therefore, a more accurate amount of the liquid W can be fed into the liquid reservoir 5.
