Description

  The present invention relates to a liquid application container for applying a liquid such as a chemical liquid, a cleaning liquid, a cosmetic liquid, and an adhesive liquid contained therein to an object.

As this type of liquid application container, for example, as shown in Patent Document 1 below, after a predetermined amount of liquid is once accumulated in a liquid reservoir, the application surface is pressed against the object to apply the liquid to the object. The structure applied to is known. In this liquid application container, it is possible to apply a certain amount of liquid stored in the liquid reservoir without causing the application amount to be excessive or insufficient.
By the way, depending on the type and application of the liquid to be applied, it may be preferable to apply a small amount (for example, several μg) of liquid several times to uniformly apply the liquid evenly to a desired range of the object. .
Utility Model Registration No. 2541327

  However, in the conventional liquid application container, for example, the amount of application varies easily every time it is applied due to the force pressing the application surface against the object, the inclination of the container, etc. There is a problem that it is difficult to uniformly apply the liquid to the desired range of the object without unevenness.

  The present invention has been made in consideration of such circumstances. After a certain amount of liquid is once stored, a small amount of liquid is applied several times from the inside, so that the desired range of the object can be uniformly distributed. It aims at providing the liquid application container which can apply | coat a liquid equally.

In order to solve the above-described problems and achieve such an object, the liquid application container of the present invention presses an application body that is inserted in and out of a minute hole against the object, thereby applying the liquid to the object. A liquid application container to be applied, which is provided with a stem erected so as to be able to be pushed in an upward biased state in a mouth portion of a container body containing the liquid, and the liquid in the container body by pushing the stem toward the inside of the container body A dispenser for discharging the liquid discharged from the container body through the inside of the stem, a liquid reservoir portion for storing the liquid discharged from the container body and storing the application body, and having the micropore formed at the tip, and the application The body is urged toward the micropore so that the tip of the coated body protrudes outside from the liquid reservoir, and the base end is brought into contact with the inner surface of the liquid reservoir to flow into the micropore. Paint with biasing body that blocks the road A first storage cylinder that includes a stopper mechanism and an overcap that is detachably attached and covers a front end portion of the liquid reservoir, and the front end of the liquid reservoir is inserted into an inner surface of the overcap And a second storage cylinder portion into which the tip of the application body is inserted , and contacts the inner surface of the liquid reservoir portion of the application body to block the flow path to the micropore. The tip side portion located on the minute hole side than the portion is formed in a smooth rod shape whose outer peripheral surface does not have a groove, and the tip portion of the liquid reservoir portion is formed in a top tube shape, At the top , the micropore having a diameter smaller than the inner diameter of the tip of the liquid reservoir is formed, and more than the portion of the liquid reservoir that the application body contacts and blocks the flow path to the micropore. The inner peripheral surface of the tip located on the micropore side has no groove Formed in smooth, the flow path, and said one of the distal portion of the applicator body, the outer peripheral surface of a portion positioned in the liquid reservoir of the tip portion, the inner peripheral surface of the distal end portion of the liquid reservoir, And extends straight in the axial direction over the entire area .
According to the present invention, since the ejector that pushes the stem toward the inside of the container body and discharges the liquid contained in the container body into the liquid reservoir portion is provided, the liquid contained in the container body is liquidized. It is possible to stabilize the amount fed into the reservoir.
Here, when the liquid is fed into the liquid reservoir, the urging body of the application plug mechanism urges the application body toward the microhole, and the base end side of the application body is the inner surface of the liquid reservoir. The flow path to the micropores is blocked by contact with the. Therefore, the liquid sent into the liquid reservoir does not flow into the micropore side and flow out to the 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. Thereby, the application body is pushed toward the inside of the liquid reservoir so as to be submerged from the minute hole. Then, the base end side of the application body also follows this and moves to the inside of the liquid pool portion, so that the base end side is separated from the inner surface of the liquid pool portion, and the flow path 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.
Therefore, it is possible to suppress a change in the coating amount each time coating is performed, and by applying a small amount of liquid a plurality of times, the liquid can be evenly applied to a desired range of the object without unevenness.
Since the liquid flows out through a slight gap between the minute holes and the application body, even if the application body is pressed, the liquid flows out as it is due to the influence of surface tension and the like. You can keep going.

Here, the discharge device is provided with a mounting cap for mounting the discharge device to the mouth portion of the container body, and the stem is directed toward the inside of the container body by pushing down the liquid reservoir portion toward the container body side. A stopper that restricts the movement of the overcap toward the container body may be provided between the mounting cap and the overcap.
In this case, a stopper for restricting the movement of the overcap toward the container body is provided between the mounting cap for mounting the discharger on the mouth of the container body and the overcap covering the tip of the liquid reservoir. Therefore, even if an external force is unexpectedly applied to the overcap with the overcap attached to the container, the overcap can be prevented from moving toward the container body. Therefore, it is possible to prevent the liquid reservoir from being pushed down toward the container body together with the stem due to an external force that has acted unexpectedly on the overcap, and the liquid is unexpectedly discharged from the container body and sent into the liquid reservoir. Can be prevented.

Further, the container body and the discharger may be arranged coaxially with each other, and the urging direction of the application body by the urging member may be orthogonal to the common axis of the container body and the discharger.
In this case, since the urging direction of the application body by the urging body is orthogonal to the common axis of the container body and the discharge device, the stem is directed toward the inside of the container body while the liquid application container is gripped. After being pushed in, the applied body can be pressed against the object in the same posture without changing the posture of the hand, and the operability can be improved.

Furthermore, the connecting cylinder that connects the discharger and the liquid reservoir may be formed with a pushing surface portion that extends in a direction orthogonal to the pushing direction of the stem.
In this case, since the pushing surface portion is formed in the connecting cylinder, the stem can be pushed easily and reliably toward the inside of the container body, and the operability can be further improved.

  According to the liquid application container according to the present invention, after a certain amount of liquid is once accumulated, a small amount of liquid is applied multiple times to uniformly apply the liquid to the desired range of the object without unevenness. be able to.

Here, the container body 13 and the cylinder 21 and the stem 22 of the discharger 14 are each formed in a circular shape in a cross-sectional view, and are arranged coaxially with the common shaft. Hereinafter, this common axis is referred to as an axis L. Further, along this axis L, the description will be given below with the mouth 13b side of the container body 13 as the upper side and the bottom side of the container body 13 as the lower side.

  A flange portion 21 a projects from the upper end portion of the cylinder 21 outward in the radial direction. The outer peripheral surface of the flange portion 21a is fitted in the mounting cap 23, and the mounting cap 23 is screwed to a male screw formed in the mouth portion 13b of the container body 13, whereby the discharge device 14 is It is attached to the mouth 13b of the body 13. Further, in this state, the flange portion 21 a is pressed through the packing 18 on the opening edge of the mouth portion 13 b of the container body 13.

  Here, at the upper end portion of the mounting cap 23, an inner tube portion 23a and an outer tube portion 23b surrounding the inner tube portion 23a are extended upward. The upper cylinder 24 fitted to the upper end portion of the stem 22 is fitted inside the inner cylinder portion 23a of the mounting cap 23 so as to be movable up and down. The upper cylinder 24 includes a small-diameter cylindrical portion 24a and a large-diameter cylindrical portion 24b that are arranged coaxially with the axis L, and is connected in this order from the upper side to the lower side. The inner cap 23a of the mounting cap 23 is fitted to the inner cap 23a so as to be movable up and down.

  Further, a rod member 25 is fitted inside the cylinder 21, and its upper end reaches an intermediate part in the stem 22. Further, a spring 26 that supports the stem 22 in an upward biased state is disposed in a cylindrical space defined by the outer peripheral surface of the rod member 25, the inner peripheral surface of the cylinder 21, and the lower end edge of the stem 22. Yes. Further, a portion located below the rod member 25 in the cylinder 21 communicates the inside of the pipe 27 connected to the lower end opening of the cylinder 21 and the inside of the cylinder 21 in accordance with the fluctuation of the internal pressure of the cylinder 21. A spherical valve body 28 for blocking is disposed.

  Here, in the present embodiment, the liquid reservoir 15 is connected to the discharger 14 via the connecting cylinder 29. The connecting cylinder 29 has a fitting cylinder part 30 in which the small-diameter cylinder part 24a of the upper cylinder 24 is fitted, and a fitting cylinder part 30 that surrounds the fitting cylinder part 30 from the outside in the radial direction and that the overcap 17 can be detached. The mounting cylinder portion 31, the outer peripheral surface of the fitting cylindrical portion 30 and the inner peripheral surface of the mounting cylindrical portion 31, and the upper surface of the connecting flange portion 32 extending upward. The stopper cylinder part 33 and a flange-shaped pushing surface part 34 projecting from the outer peripheral surface of the mounting cylinder part 31 over the entire circumference in the radially outward direction.

  A male screw is formed on a portion of the outer peripheral surface of the mounting cylinder portion 31 located above the push-in surface portion 34, and a female screw is formed on the inner peripheral surface of the open end portion of the overcap 17, and these male screw and female screw are formed. And the overcap 17 are detachably attached to the connecting cylinder 29. Further, a portion of the outer peripheral surface of the mounting cylinder portion 31 located below the push-in surface portion 34 is inserted inside the outer cylinder portion 23b of the mounting cap 23 so as to be movable up and down. Further, a flange portion 17a is projected from the open end of the overcap 17 over the entire circumference.

  The liquid reservoir portion 15 is formed in a cylindrical shape, and the base end side located on the lower side is inserted between the stopper tube portion 33 and the mounting tube portion 31 and fixed to the connecting tube 29. Thereby, the inside of the liquid reservoir portion 15 and the inside of the stem 22 communicate with each other through the inside of the upper cylinder 24 and the inside of the fitting cylinder portion 30 in the connecting cylinder 29. A flange portion 15 a that abuts against the upper end opening edge of the mounting cylinder portion 31 protrudes from the outer peripheral surface of the liquid reservoir portion 15. In addition, a minute hole 15b through which the application body 12 is inserted and retracted is formed at the center of the upper end (tip) of the liquid reservoir 15.

The application plug mechanism 16 includes an application body 12 and an urging body 35 that is formed integrally with the application body 12, and is stored in the liquid reservoir 15. In addition, the application body 12 and the urging body 35 may not be integrally formed, but the application stopper mechanism 16 may be configured by combining them independently of each other.
A portion on the tip 12b side of the application body 12 is formed as a rod-like body extending along the vertical direction, and is inserted into the micro hole 15b so as to be movable along the vertical direction. On the other hand, the diameter of the application body 12 on the base end 12a side is gradually increased from the tip end 12b side toward the base end 12a.

  The urging body 35 is a spring formed of, for example, a resin material, and the upper end is fixed to the base end 12a of the application body 12, and the lower end is fixed to the upper end edge of the stopper cylinder portion 33 via the fixing ring 12c. ing. The urging body 35 constantly urges the applicator body 12 upward, and causes the distal end 12b of the applicator body 12 to protrude outward from the liquid reservoir portion 15 in an unloaded state. The outer peripheral surface on the side is brought into contact with the inner surface of the liquid reservoir 15 to block the flow path 15c to the minute hole 15b.

  Here, on the inner surface on the upper end side of the overcap 17, the first storage cylinder portion 17b into which the upper end portion of the liquid reservoir portion 15 is inserted when the overcap 17 is attached to the attachment cylinder portion 31, and the minute hole 15b. A second storage cylinder portion 17c into which the tip of the application body 12 projecting outward is inserted and extends downward.

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. 2 and 3.
First, from the state shown in FIG. 1, the overcap 17 is rotated about the axis L with respect to the mounting cylinder portion 31 to unscrew the male screw and the female screw, and the overcap 17 is removed from the connecting cylinder 29.

Next, as shown in FIG. 2, by pushing down the pushing surface portion 34, the connecting cylinder 29, the liquid reservoir portion 15, and the upper cylinder 24 are also pushed down, and the stem 22 is pushed into the cylinder 21. At this time, the liquid pressure in the cylinder 21 increases, so that the liquid in the cylinder 21 flows between the stem 22 and the rod member 25, the inside of the stem 22, between the stem 22 and the upper cylinder 24, and the upper cylinder. 24 and the fitting cylinder portion 30 pass in this order and flow into the liquid reservoir portion 15. As a result, the liquid W is once stored in the liquid reservoir 15.
Thus, since the liquid W accommodated in the container body 13 is sent into the liquid reservoir 15 using the discharge device 14, the amount can be stabilized.

  Here, when the liquid W is stored in the liquid reservoir 15, the urging body 35 urges the application body 12 along the axis L toward the minute hole 15 b, and the base end 12 a of the application body 12. The side is brought into contact with the inner surface of the liquid reservoir 15 to block the flow path 15c to the minute hole 15b. Therefore, the liquid W sent into the liquid reservoir 15 does not flow into the minute hole 15b side and flow out to the outside.

  Next, after a certain amount of liquid W is stored in the liquid reservoir 15, the tip of the application body 12 is applied with a force that resists the urging body 35 while holding the liquid application container 10 as shown in FIG. 12b is pressed against the object. Thereby, the application body 12 moves toward the liquid reservoir 15 so that the tip 12a is submerged from the minute hole 15b. Then, the base end 12a side of the application body 12 is also moved to the inside of the liquid reservoir 15 along with this, so that the contact is released away from the inner surface of the liquid reservoir 15 and the flow path 15c toward the microhole 15b is released. Is released. As a result, the liquid W stored in the liquid reservoir 15 can be exuded by a minute amount to the outside through the gap between the minute hole 15b and the application body 12, and a very small amount (for example, several μg) of the object can be obtained. Liquid W can be applied.

Accordingly, it is possible to prevent the coating amount from changing every time the coating is performed. By applying a small amount of the liquid W a plurality of times, the liquid W can be evenly applied to the desired range of the object without unevenness. it can.
In addition, since the liquid W flows out through a slight gap between the minute hole 15b and the application body 12, even if the state where the application body 12 is pressed is maintained, the liquid W is affected by the surface tension and the like. W can be kept from flowing out as it is.

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, instead of the connecting cylinder 29 and the overcap 17 shown in the above embodiment, a configuration as shown in FIG. 4 may be adopted.

In the connecting cylinder 40 shown in FIG. 4, the outer end surface of the mounting cylinder part 41 into which the proximal end side of the liquid reservoir part 15 is inserted is radially outward at each position opposite to the axis line L in the radial direction. Pushing surface portions 42 are provided so as to protrude toward the surface. Further, on the outer peripheral surface of the mounting cylinder portion 41, a first engagement protrusion that extends along the circumferential direction between the pair of pressing surface portions 42 and at a portion positioned above the pressing surface portions 42. 43 protrudes. A pressing protrusion 44 extending downward is provided at one peripheral end of the first engagement protrusion 43.
On the other hand, the overcap 45 shown in FIG. 4 is provided with a second engagement protrusion 46 extending along the circumferential direction at an open end on the inner peripheral surface thereof.

In the above configuration, the overcap 45 is engaged with the first engagement protrusion 43 in a state where the second engagement protrusion 46 is pressed against the pressing protrusion 44, so that the mounting cylinder 40 is attached to the overcap 45. It is attached to the part 41.
Further, a stopper plate 47 extending downward is provided at the open end edge of the overcap 45. Then, in a state where the overcap 45 is mounted on the mounting tube portion 41 of the connecting tube 40 as described above, the lower end of the stopper plate 47 abuts or approaches the upper end edge of the outer tube portion 23b of the mounting cap 23, The side surface of the stopper plate 47 is in contact with or close to the side surface of the pushing surface portion 42.

As a result, even if an external force is unexpectedly applied to the overcap 45 in a state where the overcap 45 is attached to the container 48, the tip of the stopper plate 47 abuts on the upper end edge of the outer cylinder portion 23b. It is possible to prevent the cap 45 from moving toward the container body 13 side. Therefore, it is possible to prevent the liquid reservoir 15 and the connecting cylinder 40 from being pushed down toward the container body 13 together with the stem 22 by an external force that has acted unexpectedly on the overcap 45, and the liquid W is unexpectedly moved to the container body. It is possible to prevent the liquid 13 from being discharged and fed into the liquid reservoir 15.
Furthermore, in the liquid application container 48 configured as described above, when the overcap 45 is rotated with respect to the connecting cylinder 40 so that the second engagement protrusion 46 is separated from the pressing protrusion 44. The overcap 45 can be removed from the connecting cylinder 40 by releasing the engagement between the second engagement projection 46 and the first engagement projection 43 without hitting the stopper plate 47 against the pushing surface portion 42.

Moreover, it may replace with the connection pipe | tubes 29 and 40 shown in FIGS. 1-4, and a structure as shown in FIG. 5 may be employ | adopted.
The connecting cylinder 51 shown in FIG. 5 includes a fitting cylinder part 30 and a first attachment cylinder part that surrounds the fitting cylinder part 30 and extends upward from the inside of the outer cylinder part 23 b of the attachment cap 23. 52, a second mounting cylinder portion 53 extending outward in the radial direction of the container body 13 on the outer peripheral surface of the first mounting cylinder portion 52, and outward from the fitting cylinder portion 30 in the radial direction. A protruding cylindrical portion 54 that extends and communicates with the inside of the fitting cylindrical portion 30 and the liquid reservoir portion 15, and an outer peripheral surface of the protruding cylindrical portion 54 and a second mounting cylindrical portion 53 on the outer peripheral surface of the fitting cylindrical portion 30. And a stopper cylinder portion 55 that protrudes outward in the radial direction and has a fixing ring 12c fixed to a tip edge thereof. An upper end surface 52a of the first mounting cylinder portion 52 is a flat surface (pushing surface portion) extending along the radial direction. Further, the protruding cylinder portion 54 protrudes toward the tip end side in the liquid reservoir portion 15.

The base 15 of the liquid reservoir 15 is inserted between the inner peripheral surface of the second mounting cylinder 53 and the outer peripheral surface of the stopper cylinder 55 and is fixed to the connecting cylinder 51. Thereby, the urging direction of the application body 12 by the urging body 35 is orthogonal to the axis L, that is, the axis L 1 of the liquid reservoir 15 extends along the radial direction of the container body 13. The second mounting cylinder part 53, the protruding cylinder part 54, and the stopper cylinder part 55 are arranged coaxially with the axis L1 of the liquid reservoir part 15, respectively.
Further, a male screw is formed on the outer end of the second mounting cylinder 53 in the radial direction so that the overcap 17 is removably screwed. A flange portion 17 a protruding from the open end of the overcap 17 over its entire circumference is in contact with or close to the upper end edge of the outer cylinder portion 23 b of the mounting cap 23.

Even in the above-described configuration, even if an external force is unexpectedly applied to the overcap 17 or the first mounting cylinder portion 52 with the overcap 17 attached to the container 50, the flange portion 17a of the cap 17 is not affected. By contacting the upper end edge of the outer cylinder part 23b, it is possible to prevent the overcap 17 and the first mounting cylinder part 52 from moving toward the container body 13 side. Therefore, it is possible to prevent the liquid reservoir 15 and the connecting cylinder 51 from being pushed down together with the stem 22 toward the container body 13 due to an external force that has acted unexpectedly on the overcap 17 or the first mounting cylinder 52. It is possible to prevent the liquid W from being unexpectedly discharged from the container body 13 and fed into the liquid reservoir 15.
Further, since the aforementioned urging direction is perpendicular to the axis L, the posture of the hand is not changed after the liquid reservoir 15 is pushed down together with the stem 22 while the liquid application container 50 is held. It is possible to press the application body 12 against the object in the same posture, and the operability can be improved.

Furthermore, in each said embodiment, the pump provided with the stem 22 stood up so that it could push in from the upper end of the cylinder 21 arrange | positioned in the container body 13 and the upper end of the cylinder 21 as the discharge device 14 was shown. However, it can be applied to a so-called aerosol type dispenser that does not have the cylinder 21 instead.
Furthermore, instead of the discharger 14, for example, a conventionally known general pump or spray that does not have the upper cylinder 24 may be employed.

Further, the liquid reservoir portion 15 may be formed of a transparent or translucent material whose inside can be seen through from the outside.
In this case, the remaining amount of the liquid W in the liquid reservoir 15 can be visually confirmed, and the liquid W is fed into the liquid reservoir 15 before the application operation is performed again after performing the application operation once. It can be easily determined whether or not it is necessary.

  After a certain amount of liquid is once accumulated, a small amount of liquid is applied a plurality of times, so that the liquid can be uniformly applied to a desired range of the object.

It is a partial longitudinal cross-sectional view which shows the liquid application container shown as one Embodiment which concerns on this invention.
