Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a liquid material applicator used in an application operation such as an advertisement or a signboard.
[0002]
[Prior art]
When a brush or brush is used to apply ink or paint over a wide area such as an advertisement or a signboard, it is necessary to apply the ink or paint while replenishing the brush or brush frequently in a coating solution. However, applying a brush or brush repeatedly in a coating solution while replenishing ink or paint frequently makes the operation complicated and cannot be efficiently applied. Moreover, the applied state was likely to be uneven.
[0003]
[Problems to be solved by the invention]
Therefore, the applicant has considered an applicator that forms a storage chamber for storing paint in the handle portion and supplies the coating material from the storage chamber to the application section. When the applicator is not used, the applicator is covered with a cap to prevent the applicator from drying.
[0004]
When such an applicator is used, the cap is removed from the applicator, and the applicator is applied to the portion to be applied. However, at the start of use, it is expected that the coating part will dry and the amount of paint will be insufficient, or that it will take time until the coating part is sufficiently replenished with paint.
[0005]
In addition, when storing without using the applicator, in order to prevent the paint from leaking into the cap placed on the applicator, a valve is provided on the replenishment path from the coating liquid storage chamber to the applicator. It is conceivable that the passage is blocked by this valve, but if this is done, the application part will further dry, and it will take a considerable amount of time to become usable.
[0006]
The present invention has been made paying attention to the above-mentioned problems, and the object of the present invention is to provide a liquid applicator that shortens the time until it can be used when the applicator starts to be used. It is to provide.

The coating tip 2 is formed by holding a coating core member 12 on an attachment frame 11, and the coating core member 12 is a plate-shaped suction member having a predetermined thickness cut out in a T shape as shown in FIGS. A so-called hammerhead-type coating core is formed from the liquid member. Further, as shown in FIG. 4, the coating core member 12 has a multilayer structure in which an inner core member 13 and an outer core member 14 are overlapped. Specifically, one inner core member 13 is formed from two sides. A three-layer sandwich structure in which the outer core material 14 is sandwiched between the outer core materials 14 and the both surfaces of the inner core material 13 are covered with the outer core material 14 is used. Both the inner core member 13 and the outer core member 14 are formed by solidifying resin fibers into a plate shape. The inner core member 13 uses, for example, polyester or acrylic fibers, and the outer core member 14 includes, for example, polyester. Made of fiber.
[0015]
Further, by thickening the fibers of the inner core material 13 serving as the intermediate layer and thinning the fibers of the outer core material 14, gaps (gaps) between the fibers of the inner core material 13 serving as the intermediate layer and the fibers are removed. It is bigger than the one. Therefore, the inner core material 13 serving as an intermediate layer is faster in liquid absorption and oozing of liquid paint such as ink than the outer core material 14 layer.
[0016]
As shown in FIG. 5, the mounting frame 11 is formed with a box-shaped storage portion 21 into which a plate-shaped coating core member 12 formed in a T-shape is fitted substantially densely. An attachment cylinder portion 23 connected to the tip of the handle portion 1 through a connection cylinder portion 22 having a rectangular cross-sectional shape extending from the connection portion is provided continuously. On the inner peripheral surface of the mounting cylinder portion 23, a female screw portion 24 that is screwed into the male screw portion 6 of the handle portion 1 is formed. Here, the width | variety of the connection cylinder part 22 is smaller than the diameter of the attachment cylinder part 23, and this connection cylinder part 22 is formed as a neck part.
[0017]
The application portion 12a of the plate-shaped coating core member 12 formed in a T shape is disposed by being fitted in the box-shaped storage portion 21 of the mounting frame 11, and the intermediate leg portion 12b of the T-shaped coating core member 12 is disposed. Are arranged so as to enter the connecting cylinder part 22. The coating core member 12 is attached so as to be slidable in the longitudinal axis direction of the handle 1. Further, rib-shaped protrusions formed along the longitudinal axis direction of the handle portion 1 on the inner wall surfaces of the storage portion 21 and the connecting tube portion 22 corresponding to the outer surfaces of the plate-shaped coating core member 12 formed in a T shape. 25 are formed at predetermined intervals as appropriate. By forming the rib-shaped protrusion 25, the outer surface of the coating core member 12 does not completely adhere to the inner wall surfaces of the storage portion 21 and the connecting tube portion 22, and the handle portion 1 is at least between the protrusions 25. A gap 26 leading to the paint supply port is formed. Further, a groove may be formed on the side surface of the coating core member 12, or a hole may be formed in the wall portion of the coating core member 12, and the action of guiding the liquid paint to the coating tip side may be promoted using this. .
[0018]
As shown in FIG. 3, a storage chamber 31 for storing a liquid paint such as ink is formed inside the handle 1. A liquid storage chamber 31 may be formed by inserting a cartridge into the handle 1.
[0019]
A passage for supplying a liquid material from the storage chamber 31 to the coating core member 12 is formed in the opening end portion of the handle portion 1, and communicates with the passage to connect the coating core member from the storage chamber 31 to the connecting cylinder portion 22. A passage 32 for supplying a liquid material to 12 is formed. A passage in the opening end of the handle 1 is provided with a normally closed valve device 33 which will be described later. By opening and closing the valve device 33, the amount of liquid material supplied to the coating tip 2 from the paint supply port of the storage chamber 31 of the handle 1 is controlled.
[0020]
The valve device 33 is configured as shown in FIG. That is, a cylindrical resin member is used as the holding frame 35, and the valve seat member 36 is fitted into the opening end of the holding frame 35. A valve hole 38 that faces the valve body 37 is formed in the center of the valve seat member 36. The valve body 37 is formed as an inclined surface 39 having a tapered surface facing the valve hole 38. The supply path is closed when the inclined surface 39 of the valve body 37 hits the edge of the valve hole 38, and the supply path is opened when the inclined surface 39 of the valve body 37 moves away from the edge of the valve hole 38.
[0021]
A long support rod 41 extending toward the storage chamber 31 is connected to one end of the valve body 37. Further, the other end of the valve body 37 is continuously provided with a cylindrical portion 42 protruding toward the application tip portion 2 side. The cylindrical portion 42 is loosely fitted into the valve hole 38 of the valve seat member 36 and is provided so as to sufficiently protrude from the outer surface of the valve seat member 36 into the passage 32. A plurality of passages 32 that are partially cut away are formed at the protruding front end edge of the cylindrical portion 42. This passage 32 is for allowing the coating material to enter the inside of the cylindrical portion 42 even when the cylindrical portion 42 of the valve device 33 hits the intermediate leg portion 12 b of the coating core member 12.
[0022]
The support rod 41 is slidably fitted into a through hole 44 formed at the center of the distal end wall 43 of the holding frame 35. In the holding frame 35, a coil spring 45 is loosely wound around the support rod 41 as an elastic biasing means. One end of the coil spring 45 is applied to the back surface of the valve body 37, and the other end of the coil spring 45 is applied to the distal end wall 43 of the holding frame 35. Since the valve body 37 always receives the elastic restoring force of the coil spring 45 and is biased in the closing direction, the valve device 33 is normally held in a closed state by the valve body 37.
[0023]
A flange 46 protruding outward is formed at the opening end of the holding frame 35. A flange 47 is formed on the periphery of the valve seat member 36. In addition, the flange 46 of the holding frame 35 and the flange 47 of the valve seat member 36 are overlapped. In this state, the valve device 33 is tightly fitted into the mounting cylinder portion 23 of the application tip portion 2. The holding frame 35 of the valve device 33 is clamped by sandwiching and tightening the overlapped flanges 46 and 47 between the inner end peripheral wall of the mounting cylinder part 23 and the opening end of the handle part 1. Fix to part 1.
[0024]
The front end side portion of the holding frame 35 is formed in a tapered shape so as to form a large gap with the inner wall surface of the storage chamber 31. A plurality of window holes 48 are formed in the front end side portion of the holding frame 35, and the storage chamber 31 and the inside of the holding frame 35 are communicated with each other through these window holes 48.
[0025]
On the other hand, the cap 3 is covered and held so as to cover the coating core member 12 of the coating tip 2. That is, as shown in FIG. 3, the flange 52 formed on the peripheral edge of the mounting cylinder portion 23 is fitted in the groove 51 formed on the peripheral edge of the cap 3 and is sealed with the seal member 53. Further, as shown in FIG. 1, the cap 3 is provided with a locking piece 56, and the locking hole 57 of the locking piece 56 is locked to a protrusion 55 formed on the side surface of the mounting frame 11, thereby fixing the cap 3. It is held on the mounting frame 11.
[0026]
Next, the effect | action of the applicator of this embodiment is demonstrated. When the applicator is not in use, the applicator tip 2 is covered with a cap 3 and the valve device 33 is closed. For this reason, since the coating material is not supplied from the storage chamber 31 to the coating tip portion 2, the coating material does not overflow into the cap 3 through the coating core member 12.
[0027]
Moreover, when using an applicator, the cap 3 is removed from the application | coating front-end | tip part 2, and the application | coating core member 12 of the application | coating front-end | tip part 2 is repeatedly pushed in. When the coating core member 12 is pushed in, the intermediate leg portion 12 b of the coating core member 12 pushes the valve element 37 against the urging force of the coil spring 45 through the cylindrical portion 42 of the valve device 33. Then, the valve body 37 is separated from the valve seat member 36, opens the valve hole 38, and opens the valve device 33, so that the coating material is supplied from the storage chamber 31 to the application tip portion 2. By repeating the operation of pushing the coating core member 12, a large amount of paint can be supplied to the coating core member 12. When this pushing operation is repeated, the coating core member 12, the valve body 37, and the like exhibit a pumping action. In addition, since both the inner core member 13 and the outer core member 14 of the coating core member 12 are formed so as to exhibit liquid absorbency and permeability due to a capillary phenomenon in the gap between the fibers, the coating material should be distributed throughout. Ooze out. Therefore, even if the coating tip 2 is directed upward, the coating material can be sufficiently supplied to the coating core member 12. Then, the push-in operation is repeated until it can be used. However, at this time, if the coating tip 2 is directed downward, the coating material can be efficiently supplied to the coating core member 12.
[0028]
In this way, the liquid paint can be used by spreading from the intermediate leg portion 12b of the coating core member 12 to the entire coating portion 12a.
[0029]
In the present embodiment, the coated core member 12 is faster in liquid absorption and oozing out of the liquid coating material of the inner core material 13 serving as an intermediate layer than the layer of the outer core material 14. For this reason, the liquid paint oozes out to the tip end portion of the coating core member 12 through the inner core member 13, the flow rate is increased, and the initial liquid discharge time can be shortened. For example, when the number of pushes is 20, it is completed in 10 to 15 times. The inner core member 13 is generally weak in strength, but is protected by the outer core member 14 and the coating core member 12 is reinforced to increase the strength of the coating core member 12 and ensure the durability of the coating tip 2. can do.
[0030]
The present invention is not limited to the embodiment described above, and can be applied to other forms. The coating core member 12 of the above-described embodiment is such that both sides of one inner core member 13 are sandwiched between two outer core members 14, but has a two-layer structure in which one outer core member 14 is omitted. It may be a thing. Even in a four-layer structure in which the inner core member 13 and the outer core member 14 are alternately stacked, a plurality of inner core members 13 may be stacked in five or more layers so as to be sandwiched between those corresponding to the outer core member 14. Good. Moreover, the material which forms the fiber of the inner core material 13 and the outer core material 14 may be made of another resin.
[0031]
