Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an applicator having a liquid discharge unit in an applicator main body for containing a coating liquid.

  Conventionally, when the tip end of the front shaft is simply increased in order to widen the application width, the applicator is vertically stood in order to ensure that both widthwise end portions of the tip end of the front shaft contact the object to be coated. Since it must be applied in the state, and the user's holding method of the application tool is limited and there is a possibility that usability may be deteriorated, the tip axis is deformed in such a direction as bending the center axis of the tip axis. At the time of application, even if the applicator is held by tilting the application tool back and forth or left and right in the moving direction, at least the tip of the front shaft can be made substantially upright by deforming the front shaft. The ingredients are known.

Japanese Utility Model Publication 7-31172

However, in the applicator described in Patent Document 1, in order to incline the applicator back and forth or to the left and right in the moving direction, the front shaft is deformed using the thickness difference between the groove portion provided on the front shaft and both side portions. However, since deformation of the material of the fore-end shaft itself is used, there is a risk that it may be deformed at an unexpected position, and it may not be possible to apply it by tilting it at a desired angle.
In addition, when the material of the front shaft is configured to be elastically deformed, there is a fear that the application mark will not be as expected because an unexpected force is generated to return the bent front shaft to the original state by the elastic force. The

  The present invention is a first aspect of an applicator in which a separate application member is rotatably connected by a bearing joint structure to a liquid discharge portion of an applicator body containing an application liquid, and the bearing joint structure The second aspect of the present invention is a coating tool having a ball joint mechanism in which a concave portion is formed in one of the liquid discharge portion or the application member and a convex portion is formed in the other, and at least one of the concave inner surface or the convex outer surface is formed by a curved surface. Further, the application member has an application surface which spreads the application liquid, and the application surface is provided with a projection which forms a gap between the application surface and the application surface. It is a summary.

  According to the present invention, the separate application member is rotatably connected to the liquid discharge portion of the applicator body by the bearing joint structure, so that the applicator body is rotated within a predetermined range with respect to the application member. It is easy to control the movement of the applicator body with respect to the application member, and it is possible to obtain a desired application mark with a wide application width.

The applicator according to the present invention comprises: an applicator body having an application liquid storage portion for containing an application liquid, and a liquid discharge portion having a discharge port which is an outlet for discharging the application liquid onto the surface to be coated; And an application member configured as a separate member are connected by a joint structure of a bearing by a combination of elements such as a hinge and a ball joint.
The application member can apply the application liquid to the application surface by interposing the application liquid discharged from the liquid discharge unit between the application member and the application surface.
In the present invention, “front” refers to the tip end side of the liquid discharge unit, and “rear” refers to the opposite side.

FIGS. 1 to 7 show the case where the rotation due to the bearing joint structure is a hinge-like rotational movement centering on a rod-like rotation axis.
The application member and the applicator body are coaxial centers on the application member and the applicator body such that the recess and the projection form a rotational axis of rotation restraint motion of the application member. To form a hinge-like bearing joint structure in which the convex portion is a rotary shaft and the concave portion is a rotary bearing. With this bearing joint structure, the tilt of the applicator body with respect to the application member can be changed by the rotational movement of the applicator body with respect to the application member, so it is easy to control the movement of the applicator body with respect to the application member It is possible to obtain a wide application mark as expected. The number of the convex portions is not limited to one, and two or more convex portions may be formed as long as they are linearly extended, and the convex portions and the concave portions may be formed on any one of the application member and the applicator body. And the other may also be formed with a recess and a protrusion. When a plurality of protrusions are provided, the recesses may be formed to respectively contain the protrusions.
The bar-like shape of the convex portion may be cylindrical, and the concave portion containing the convex portion may be cylindrical as well, and by making the curved surfaces mutually, smoother rotational motion can be performed, but the present invention is limited thereto. Alternatively, only one of the outer surface of the convex portion and the inner surface of the concave portion may be formed as a cylindrical surface as long as the convex portion is a rotational shaft and the concave portion is a rotational bearing.
The convex portion and the concave portion may be integrally formed on the application member or the applicator body, or may be separately formed.

FIGS. 8 to 17 show the case where the bearing joint structure is a ball joint mechanism which is a spherical rotational motion in which the restraining motion is not defined in one direction.
The application member and the applicator body form a convex portion on either one of the application member and the applicator body, the other includes the convex portion, is guided by the outer surface of the convex portion, and rotates By forming a moving recess and forming at least one of the convex outer surface or the recess inner surface as a curved surface, a bearing joint structure consisting of a ball joint mechanism capable of spherical rotational movement in which a restraining motion is not defined in one direction is formed. ing. With this bearing joint structure, it is possible to change the tilt of the applicator body with respect to any direction in the radial direction from the center within the range rearward from the center of the spherical rotational movement, and in a state where it remains inclined. Since the applicator body can be moved circularly from the center of the spherical rotational movement, the range of movement is wider than the bearing joint structure consisting of the rotational movement, and the movement of the applicator body relative to the application member is controlled It is easy to do, and it is possible to obtain a wide application mark as expected.
The curved surfaces of the convex portion and the concave portion may not be completely continuous curved surfaces as long as they can spherically rotate.
Further, by forming the curved surface as a spherical surface, a smoother spherical rotational movement is possible.
The convex portion and the concave portion may be integrally formed on the application member or the applicator body, or may be separately formed.

  The material of the application member is a resin such as polyoxymethylene, polybutylene terephthalate, polyethylene, polypropylene, polyamide, polyetherketone, polyetheretherketone, acrylic resin, polycarbonate, polyurethane, vinyl chloride resin, silicone resin, rubber, elastomer, etc. A single material or a mixture of materials or metal-plated materials such as these resins, metals or alloy materials such as aluminum, iron, stainless steel, brass, nickel, brass, etc., acrylic fiber whose coating member itself holds ink, nylon It may be a fiber, there is no deterioration such as dissolution or decomposition of the application member due to the application liquid, shape change such as swelling or contraction does not significantly impair the rotation or the application performance, and the bearing joint occurs at the time of rotation of the applicator body Wear resistance of the structure, mechanical motility of the bearing joint structure, etc. Considering, it may be appropriately set.

The material of the coating liquid storage unit may be any material that does not deteriorate or change in shape due to swelling, dissolution, decomposition, etc. by the coating liquid, and has low water vapor permeability, and it is better if formability is good. For example, when it is necessary to press the coating solution storage unit in order to deliver the coating solution to the solution discharge unit, a flexible blow molded product of resin such as nylon or polypropylene can be preferably used, and the coating solution can be used. In the case where it is not necessary to press the coating solution storage unit, such as being able to be supplied to the coating unit by free fall, a non-flexible metal such as stainless steel or brass, glass or the like may be used.
In the case where the coating solution stored in the coating solution storage unit precipitates part of its components or hardens due to drying, the coating solution storage unit stores the stirring body together with the coating solution.

The liquid discharge unit is provided with a holding member capable of temporarily holding a coating liquid such as a fibrous body or a sintered body inside the liquid discharge unit so that the coating liquid does not leak from the discharge port, or a coating member is applied The portion in contact with the application surface of the member may be formed by the holding member.
In addition, it is intended to prevent the coating liquid contained in the applicator main body from being hardened or volatilized by contact with the outside air, or to prevent the problem that the coating liquid is accidentally leaked from the liquid discharge portion. In this case, a cap may be provided to close the liquid discharge portion, or a valve mechanism may be provided in the liquid discharge portion, and after the valve mechanism is provided, the surroundings are not soiled by the application liquid remaining on the application member. You may provide the cap for that.
As the valve mechanism, a core body in which a part of the tip projects from the discharge port is disposed, an elastic member made of a spring or an expandable material is disposed behind the core body, and the core body is pressed from behind by the elastic member. In this state, when the applicator is not in use, the enlarged diameter portion formed slightly backward from the tip of the core body is in a state of being in contact with and pressed against the inside of the discharge port, The body closes the gap of the discharge port, and at the time of application, the projection of the core protruding from the discharge port is pressed against the surface to be coated to retract the core, whereby the space between the core and the discharge port A gap is formed, and a mechanism that discharges the application liquid, a ball as an application member such as a general ballpoint pen, and a ball holder that rotatably holds the ball rotatably Arranging an elastic member made of a possible material, and By pressing from behind, the gap between the ball and the ball holder is closed when the applicator is not in use, and when in use, the ball is pushed backward to form a gap between the ball and the ball holder. The mechanism for discharging the coating liquid or the mechanism for opening the valve by pressing the pressing portion provided on the applicator body can be adopted.

The application member is provided with an application surface on the tip side, and the application liquid discharged from the liquid discharge unit intervenes between the application surface and the target surface, whereby the application surface is provided on the target surface.

A first embodiment of the present invention will be described with reference to FIGS.
As shown in FIGS. 1 and 2, the applicator 1 is composed of an applicator main body 2 and an application member 3.
The applicator body 2 is composed of an application liquid storage unit 4 and a liquid discharge unit 5.

The coating liquid storage unit 4 has a space in which the coating liquid 6 can be stored, and a screw is used for filling the coating liquid at the time of manufacture and for replenishing the coating liquid consumed after use. It is comprised by the front shaft 7 and the rear shaft 8 which can be attached or detached by screwing. Further, the present embodiment is an application tool which incorporates a coating solution for making it possible to cover the concealed handwriting drawn on the application surface P or to draw the correct handwriting on the cover again. The coating liquid 6 contained in the coating liquid container 4 may have some of its components precipitated or solidified, so that the stirring liquid together with the coating liquid 6 may be contained in the coating liquid container 4. 9 is housed. Before using the applicator 1, by shaking the applicator 1, the agitating body 9 moves back and forth in the application liquid storage unit 4, the application liquid 6 is agitated, the precipitated components are mixed again, and the fluidity is achieved. You can get back.
In addition, since the rear shaft 8 of the coating liquid storage unit 4 is formed of a blow-molded article of nylon resin and has flexibility, the rear shaft 8 is inside by pressing the side surface of the rear shaft 8 Can be transformed into As a result, the inside of the coating liquid storage unit 4 is compressed, and the coating liquid 6 is supplied to the liquid ejection unit 5 by pushing the coating liquid forward by the compression force.

  The liquid discharger 5 is fixed to the front end of the front shaft 7 of the coating liquid container 4 by press fitting. The liquid discharge unit 5 includes a cylindrical chip 11 having a discharge port 10 for discharging the application liquid 6 supplied from the application liquid storage unit 4 to the outside of the application tool 1. A core 12 is disposed inside. The coil spring 13 is disposed at the rear 12 of the core, and the core 12 is pressed from behind by the coil spring 13 as an elastic member, whereby the core is not used when the applicator is not in use. The enlarged diameter portion 14 formed slightly rearward from the tip of the body is pressed against the reduced diameter portion 15 formed inside the liquid discharge portion 5, and the core 12 closes the discharge port 10, The coating solution can be prevented from leaking from the discharge port 10 when the applicator is not in use. And at the time of application, the enlarged diameter portion 14 of the core 12 is pressed by pressing the tip portion (protruding portion 16) of the core protruding from the discharge port 10 against the surface P to be coated P to retract the core 12. A gap is formed between the reduced diameter portion 15 of the liquid discharge portion 5 and the valve mechanism which discharges the coating liquid.

The application member 3 is formed at its front end with an application surface 17 having a square outer shape. Further, at the center of the application member 3, a communication passage 18 communicating with the rear end of the application member 3 from the application surface 17 formed at the front end is formed.
The material of the application member does not deteriorate due to dissolution or decomposition by the application liquid, and the shape change such as swelling or contraction does not significantly impair the slidability with the liquid discharge portion and the application performance. Polyoxymethylene is used in consideration of the slidability with respect to the surface P, the removability of the coating liquid adhering to the coating member, and the like.
The fluid discharger 5 is inserted into the communication passage 18 and is connected by a hinged bearing joint structure.

The bearing joint structure in the present embodiment will be described. (See Figures 3-7)
On the outer peripheral surface of the liquid discharge portion 5, a cylindrical convex portion 19a and a convex portion 19b are formed which project from the outer peripheral surface in a direction perpendicular to the axis of the liquid discharge portion. The convex portion 19a and the convex portion 19b are formed at positions opposed to each other such that their axes are on a straight line. (See Figures 3-4)
Further, the inner surface of the communication passage 18 of the application member 3 is recessed toward the outside from the inner surface, and a cylindrical recess 20a that inwards the protrusion 19a, and a cylindrical recess that includes the protrusion 19b. 20b is formed. The recess 20a and the recess 20b are also formed at mutually opposite positions and with their axes being in a straight line, as in the case of 19a and 19b. (See Figure 5)
The application member 3 is engaged with the liquid discharge portion 5 by inserting the liquid discharge portion 5 into the communication passage 18 and including the 19a and 19b by the 20a and 20b. Since the recesses 20a and 20b are slightly larger than the protrusions 19a and 19b, the inner peripheral surfaces of the recesses 20a and 20b are in contact with the outer peripheral surface of the protrusions 19a and 19b. It has a hinge-like bearing joint structure in which the convex portion is a rotational shaft and the concave portion is a rotational bearing. (See Figure 3)
By this bearing joint structure, as shown in FIGS. 6 to 7, the applicator main body 2 can be freely inclined within a predetermined range with respect to the application surface 17 of the application member 3. It is easy to control the movement of the main unit, and it is possible to obtain the desired application trace.
6 to 7 show a state in which the applicator main body 2 is inclined with respect to the application member 3 at the time of application, the projecting portion 16 of the core body 12 is pressed backward by the application surface P, and the core The body 12 has moved backward.

A second embodiment of the present invention will be described with reference to FIGS.
As shown in FIGS. 8-9, the applicator 21 is comprised from the applicator main body 22 and the application member 23. As shown in FIG.
The applicator body 22 is composed of an application liquid storage unit 24 and a liquid discharge unit 25.

The coating liquid storage unit 24 has a space capable of containing the coating liquid 26 formed therein, and a screw is used for filling the coating liquid 26 at the time of manufacture and for replenishing the coating liquid 26 consumed after use. It is comprised by the front shaft 27 and the back shaft 28 which can be attached or detached by screwing. Further, the present embodiment is an application tool which incorporates a coating solution for making it possible to cover the concealed handwriting drawn on the application surface P or to draw the correct handwriting on the cover again. Since some of the components of the coating solution 26 stored in the coating solution storage unit 24 may settle or harden, the stirring solution may be mixed with the coating solution 26 in the coating solution storage unit 24. 29 are housed. Before using the applicator 21, by shaking the applicator 21, the agitating body 29 moves back and forth in the application liquid storage unit 24, the application liquid 26 is agitated, the precipitated components are mixed again, and the fluidity is achieved. You can get back.
Further, since the rear shaft 28 of the coating liquid container 24 is formed of a blow-molded article of nylon resin and has flexibility, the rear shaft 28 is inside by pressing the side surface of the rear shaft 28. Can be transformed into As a result, the inside of the coating liquid storage unit 24 is compressed, and the coating liquid 26 is supplied to the liquid ejection unit 25 by pushing the coating liquid 26 forward by the compression force.

  The liquid discharger 25 is fixed to the front end of the front shaft 27 of the coating liquid container 24 by press-fitting. The liquid discharge unit 25 includes a cylindrical chip 31 having a discharge port 30 for discharging the application liquid 26 supplied from the application liquid storage unit 24 to the outside of the application tool 21. A core 32 is disposed inside. The coil spring 33 is disposed behind the core body 32. The core body 32 is pressed from behind by the coil spring 33, which is an elastic member, so that the core body is not used when the applicator is not in use. Since the enlarged diameter portion 34 formed slightly backward from the tip of the body is pressed against the reduced diameter portion 35 formed inside the liquid discharge portion 25, the core 32 blocks the discharge port 30, The coating solution can be prevented from leaking from the discharge port 30 when the applicator is not in use. Then, at the time of application, the enlarged diameter portion 34 of the core body 32 is obtained by pressing the tip portion (protruding portion 36) of the core body protruding from the discharge port 30 against the application surface P to retract the core body 32. A gap is formed between the reduced diameter portion 35 of the liquid discharge portion 25 and the valve mechanism which discharges the coating liquid.

The application member 23 is provided at its front end with an application surface 37 having a circular flat outer shape. Further, at the center of the application member 23, a communication passage 38 communicating with the rear end of the application member 23 from the application surface 37 formed at the front end is formed. (See Figures 11-12)
The liquid discharge portion 25 is inserted into the communication passage 38, and is connected by a bearing joint structure.
The material of the application member 23 has no deterioration such as dissolution or decomposition by the application liquid 26, and in addition to the fact that the shape change such as swelling or contraction does not significantly impair the slidability with the liquid discharge portion 25 and the application performance. Polyoxymethylene is used in consideration of injection moldability, slipperiness with respect to the surface P to be coated, removability of the coating liquid 26 attached to the coating member 23, and the like.

The bearing joint structure in the present embodiment will be described. (See Figures 10-15)
The bearing joint structure of the present embodiment is a so-called ball and socket joint structure.
A ring-shaped joint member 40 is fixed to an outer peripheral portion 39 of the liquid discharge portion 25 inserted into the communication passage 38. Specifically, at the front and back of the outer peripheral portion 39, the step portion 41 which is expanded in the radial direction is formed, the center hole of the ring-shaped joint member 40 inserted from the front of the liquid discharge portion 25 is formed. Since the front end surface 42 and the rear end surface 43 of the joint member 40 are pinched by the step portion 41 after passing over the step portion 41 formed in the front of the outer peripheral portion 39, the joint member 40 is It prevents you from coming off. (Refer to Figure 10, Figure 13-15)
The outer peripheral surface of the joint member 40 is formed of a spherical surface (joint member side spherical surface 44) that bulges outward (see FIGS. 10 and 13 to 14). On the other hand, on the inner surface of the communication passage 38 of the application member 23, a spherical surface (application member side spherical surface 45) which is formed with the same curvature as the joint member side spherical surface 44 and is concaved outward is formed (FIG. 10) -12). Then, by engaging the joint member-side spherical surface 44 with the application member-side spherical surface 45, a bearing joint structure formed by so-called ball joints in which the respective spherical surfaces contact and move is obtained. (See Figure 10)
With respect to the application surface 37 formed on the application member 23 by this bearing joint structure, as shown in FIGS. 16 to 17, the applicator body 22 is aft from the center of the spherical sphere from the center of the sphere. It is possible to change the inclination of the applicator body 22 within a range and with respect to any direction radially from the center thereof, and while keeping the inclination, the applicator body 22 with respect to the center of the sphere. Can be moved in a circular motion, so the range of movement is wider than the bearing joint structure consisting of the rotational movement, and the movement of the applicator main body 22 relative to the application member 23 can be easily controlled. You can get it.
16 to 17 show a state in which the applicator main body 22 is inclined with respect to the application member 23 at the time of application, the protruding portion 36 of the core body 32 is pressed backward by the application surface P, and the core The body 32 has moved backward.

The joint member-side spherical surface 44 and the application member-side spherical surface 45 have no influence on the movement when the spherical surface and the spherical surface slide, and if the coupling member 40 and the application member 23 are not disengaged, one of the spherical surfaces is used. It may be a discontinuous spherical surface in which a portion is cut and a plane is formed. In this embodiment, when the joint member 40 is manufactured by injection molding, when the gate portion which is an inlet for pouring the molding material is disposed on the outer surface on the joint member side, the gate portion remains as a burr ), Because there is a risk of preventing the spherical surface from sliding, a flat portion (flat portion 44a) slightly cut inward from the spherical surface is provided in a part of the spherical surface, and the gate portion is disposed on the plane There is. Thus, the burrs are prevented from jumping outside the spherical surface.
Moreover, in the present embodiment, the spherical surfaces of the joint member side spherical surface 44 and the application member side spherical surface 45 have the same curvature, but if there is no influence on the movement when the spherical surface and the spherical surface slide, The curvature may be different.
In the present embodiment, the tip 31 and the joint member 40 are separately formed, but may be formed by one member.

In the present embodiment, the valve portion 36 discharges the coating liquid 26 from the discharge port 30 by pressing the protrusion 36 against the surface P to be coated and moving it back during application, so the tip 31 of the liquid discharge portion 25 The tip portion and the projection 36 are disposed in front of the application surface 37.
Further, on the application surface 37, four projections 46 protruding forward from the application surface 37 are provided radially at equal intervals. By making the heights of the four projections from the application surface the same, a uniform gap is formed between the application surface and the application surface P at the time of application, and the coating liquid is between the application surface and the application surface P. It is easy to intervene. Therefore, when the protrusion 36 of the liquid discharger 25 is pressed at the time of application, a target amount of application is obtained from the gap formed between the enlarged diameter part 34 of the core 32 and the reduced diameter 35 of the liquid discharger 25. The position of the tip of the protrusion 36 is set to be forward of the plane passing through the tips of the four projections 46 so that the core 32 can be retracted by the amount that the liquid can be discharged.

  As shown in FIG. 18, the R-chamfered portion (chamfered portion 47) is formed at the boundary between the protrusion 46 and the application surface, so that the resin flow at the time of molding is improved and the stress applied to the boundary at the time of application When the coating solution is solidified after being used as an applicator, it becomes easy to remove it.
