Description

  The present invention relates to a roller type applicator. Furthermore, it is related with the roller-type applicator which supplies and supplies the liquid to accommodate to a roller.

2. Description of the Related Art Conventionally, there has been disclosed an applicator provided with a transfer roller via a porous member at the tip opening of a shaft cylinder directly containing a liquid such as ink (see, for example, Patent Document 1).
In use, the applicator is capable of transferring the ink inside the shaft tube without causing breaks in the handwriting through the roller printing surface by rotating a contact roller with the application object, but when not in use. In this case, since the ink inside the shaft cylinder continues to be supplied to the porous member and the roller, the ink may leak when the viscosity of the ink is low.

Moreover, in order to eliminate the said problem, the roller-type applicator by which a roller is spaced apart from an ink supply part (liquid absorption member) at the time of non-use and an ink leak is suppressed is disclosed (for example, refer patent document 2). .
Japanese Utility Model Publication No. 63-8994 JP-A-2005-734

  The roller-type applicator described in Patent Document 2 does not cause ink leakage when placed in a horizontal state because ink supply to the roller is stopped when not in use. When left standing for a long time in the placed state (that is, the state in which the liquid container is located above the roller), water supplied to the liquid-absorbing member cannot be held and water leakage may occur.

  The present invention solves the above problems, is excellent in liquid discharge properties during use, has no fear of causing handwriting interruptions, etc., and is not affected by the liquid to be stored, the direction when left, etc. A roller-type applicator that does not cause liquid leakage when not in use is provided.

The present invention relates to a liquid storage portion having a liquid guide member in a lower opening, a main body having the liquid storage portion disposed above and having an upper holding portion and a lower holding portion, and held in the main body. A roller-type applicator comprising a liquid-absorbing member and a roller having a support shaft held in the main body, wherein the liquid-absorbing member is held by the upper holding part so as to move up and down, and the roller The support shaft is held by the lower holding portion so that it can be moved up and down and rotated.At the time of application, the roller moves upward to contact the lower end of the liquid absorbing member, and the liquid absorbing member in contact with the roller is in contact with the roller. The roller moves upward to come into contact with the lower end of the liquid guiding member, and when not applied, the roller moves downward to move away from the lower end of the liquid absorbing member, and the liquid absorbing member moves downward to lower the lower end of the liquid guiding member. It is a requirement to move away from
Furthermore, it is a requirement that the roller is pressed downward in an upright state by an elastic member.
In the present invention, “upper” refers to the liquid container side, and “lower” refers to the roller side.

  According to claim 1 of the present invention, during use, a certain amount of liquid is continuously supplied to the roller marking surface, and when a roller is applied by rotation, a printed image can be formed without causing handwriting breakage, etc. When not in use, the liquid supply from the liquid container to the liquid absorbing member and the liquid supply from the liquid absorbing member to the roller marking surface are stopped, and the lower end of the guide member is liquid-sealed, so that liquid leakage can be more effectively prevented.

  According to the second aspect of the present invention, since the roller does not rise due to the weight of the applicator and the liquid is not supplied, the leakage of the liquid can be prevented more reliably even in the vertically placed state.

  The roller type applicator of the present invention is used with the roller side facing downward, and when not in use, the roller, the liquid absorbing member, and the liquid guiding member are maintained in a separated state. The roller to be contacted rises to come into contact with the liquid absorbing member, and further, the two members rise to come into contact with the liquid absorbing member and the liquid guiding member, so that the liquid to be accommodated in the liquid accommodating portion is passed through the guiding member. It is supplied to the liquid absorbing member, and is supplied from the liquid absorbing member to a roller (printing surface).

  The roller-type applicator includes a liquid container having a liquid guide member at least in a lower opening, a main body in which the liquid container is disposed above, a liquid absorbing member held in the main body, And a roller having a support shaft held on the surface.

The liquid storage part is a tank for storing a liquid such as water or ink, and at least a part of the lower end is opened for liquid flow. The opening portion is provided with a liquid guide member for guiding the liquid to be stored downward (liquid absorbing member). As the liquid guide member, one having a capillary force or liquid absorption force such as a fiber converging body, felt, sliver-like resin or the like is used.
The liquid guiding member can be detachably used, and the lower end opening can be used for inflow and outflow of liquid, and the lower end opening can be used for outflow of liquid, and a liquid replenishment (inflow) hole can be provided separately. At that time, it is preferable that the upper opening is provided with a stopper and sealed.
The shape of the liquid container may be any shape such as a long one in the axial direction or a long one in the radial direction.

The main body has a liquid container disposed above and a liquid absorbing member and a roller disposed therein. In that case, it arrange | positions in the state which protruded so that the lower end part of a roller could contact an application surface at least.
The main body has an upper holding portion that holds the liquid absorbing member so as to be movable up and down, and a lower holding portion that holds the roller so that the roller can be moved up and down and rotated. Can be provided with an elastic member or the like for pressing the roller downward in a vertically placed state.

The liquid absorbing member is for holding the liquid stored in the liquid storage portion and supplying the liquid to the roller. The liquid absorbing member is provided so as to come into contact with the lower end of the liquid guiding member when moving upward, and the lower portion is an applicator. It is provided so as to be in contact with the marking surface of the roller when used. As the liquid-absorbing member, a porous member capable of holding a liquid therein is used, and specifically, a fibrous body such as felt, a nonwoven fabric, and a knitted fabric, and a foamed body such as sponge. A member having a capillary force stronger than that of the liquid guiding member is used as the liquid absorbing member.
The liquid absorbing member can be accommodated by being attached to a hard resin member or the like in addition to being directly accommodated in the main body. As a result, the strength can be increased and it is difficult to be deformed for long-term use.

  The roller is a columnar object having a support shaft and having an outer peripheral surface as a marking surface, and is formed of a resin molded product, rubber, elastomer, metal, or the like. In particular, when formed with a resin molding or metal, and when using a low-viscosity liquid such as water as the liquid to be stored, an image composed of a water-absorbing member such as fabric or felt is provided on the outer peripheral surface. It is preferable to improve applicability.

When the roller-type applicator is pressed against the object to be coated during use, the roller moves upward so that the roller marking surface and the lower end of the liquid absorbing member are in contact with each other, and this state is maintained. As it moves upward, the upper end portion of the liquid absorbing member comes into contact with the lower end portion of the liquid guiding member, whereby the liquid in the upper liquid storage portion is guided by the liquid guiding member and supplied to the liquid absorbing member. Furthermore, it is supplied to the marking surface of the roller via the liquid absorbing member. In this state, the liquid is continuously supplied to the roller marking surface, and therefore, even if the roller is applied by rotation, the application can be performed without causing handwriting interruption such as blurring or line skipping.
In addition, when not in use, the roller is moved downward by its own weight or a pressing force by an elastic member and the liquid absorbing member is moved below its own weight by separating the marking surface of the roller from the object to be coated. The upper end of the liquid member is in a non-contact state with the lower end of the liquid guiding member, the lower end of the liquid guiding member is liquid-sealed, and the marking surface of the roller is in a non-contact state with the lower end of the liquid absorbing member. The liquid supply from the section to the roller marking surface stops. Therefore, even when it is left for a long time in a vertically placed state (roller downward state), the leakage of the liquid can be suppressed. In particular, when the distance from the liquid level of the liquid stored in the liquid storage unit to the lower end of the liquid guide member (the shortest distance when the liquid guide member is in a state perpendicular to the application surface) is long, the above configuration is used. The effect of suppressing liquid leakage is clearly expressed.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a longitudinal sectional view when the roller-type applicator of the present invention is used (at the time of application), and FIG. 2 is a longitudinal sectional view when not in use.

  The roller-type applicator 1 includes a hollow liquid storage portion 2 (containing water as the liquid 8) having a liquid outlet hole 21 below, and a main body 4 that detachably disposes the liquid storage portion 2 upward. The liquid absorbing member 5 is held in the main body 4 so as to be movable up and down, and the roller 6 is held in the main body 4 so as to be movable up and down and rotatable.

The liquid storage portion 2 is a hard resin container having holes in two places, upper and lower, and is detachably attached to an opening portion on the upper side of the main body 4. Of the holes, a hole provided on the lower side (bottom surface) acts as a liquid outlet hole 21, and a liquid guiding member 3 for guiding the liquid 8 is fitted into the hole. Yes. An air hole for air change is provided in the vicinity of the liquid guiding member 3.
The liquid guide member 3 is a rod-shaped object having a lower end formed of a fiber bundle, and can stably guide the liquid 8 in the liquid storage portion 2 downward by capillary force, and at the bottom when not in contact with the liquid absorbing member 5. The part is liquid-sealed, and liquid dripping can be suppressed.
Further, the hole provided on the upper side of the liquid storage unit 2 functions as a hole for injecting liquid, and is sealed by press-fitting the lid 22, and the lid 22 is opened. The liquid can be easily refilled, and the liquid to be stored is prevented from spilling when the liquid is reversed.

The main body 4 is a resin molded product that opens on the upper side to hold the liquid storage portion 2 and opens on the lower side to protrude below the roller 6. It can be made a toy form imitating various shapes. In that case, a leg part, a wheel, etc. can also be provided as needed.
Inside the side wall of the main body 4, an upper holding portion that engages and holds the liquid absorbing member 5 below the liquid storage portion 2 so as to move up and down, and a roller 6 that can move up and down and rotate below the liquid absorbing member 5. Each of the lower holding portions engaged and held is formed by injection molding as a groove portion extending in the vertical direction.
Further, an elastic member (metal spring) 7 for pressing the roller 6 downward is provided in the vicinity of the lower holding portion in contact with the support shaft 62. The elastic member 7 is not lifted by the weight of the applicator (when the liquid is contained), but has a spring force that can be easily lifted by pressing slightly downward, so that the roller 6 is lifted in the vertical state. Without any liquid induction from the ink storage unit 2.

  The roller 6 is a hollow resin molding in which a cylindrical support shaft 62 that is engaged with and held by the lower holding portion of the main body 4 is integrally formed, and a star-shaped hole portion (specifically three) is formed on the outer peripheral surface. The stamp face 61 is formed by accommodating a non-woven fabric inside and projecting the non-woven fabric from the star hole. The marking surface 61 is not peeled off from the outer peripheral surface by use, and has high liquid storage performance.

The liquid absorbing member 5 is made of a thin plate-like felt, and the upper end portion where the liquid guide member 3 made of a fiber bundle contacts (inserts) is formed in a concave shape at the upper end portion. By making it concave, contact can be made so as to cover the lower end of the liquid guiding member 3 during application, so that liquid supply to the liquid absorbing member 5 is reliably performed.
Mounting portions 51 made of a hard resin member are provided on the outer peripheral surface of the liquid absorbing member 5 (excluding the upper and lower surfaces and the vicinity thereof) so as to protrude from the upper and lower end portions of the liquid absorbing member 5, The deformation of the liquid member 5 is suppressed. The mounting portion 51 is formed with a convex portion 52 for engaging and holding with the upper holding portion of the main body 4 and formed in a rectangular cross section so that it can be lowered by its own weight without rotating in the upper holding portion. Has been.

The roller-type applicator 1 maintains a liquid-sealed state in which the liquid 8 in the liquid storage unit 2 is guided to the lower end of the liquid guide member 3 provided in the liquid outlet hole 21 in the downward state on the roller 6 side. To do.
In use, an object to be coated 9 (for example, a water having a low refractive index pigment fixed in a dispersed state in a binder resin on the surface of the base material and having different transparency between the liquid-absorbing state and the non-liquid-absorbing state. By pressing the marking surface 61 of the roller 6 against the color-changing sheet), the roller 6 moves upward, and the marking surface 61 contacts the lower end of the liquid absorbing member 5. Further, the roller 6 and the liquid absorbing member 5 move upward in the contact state, and the upper end portion of the liquid absorbing member 5 comes into contact with the lower end portion of the liquid guiding member 3, so that the liquid 8 is liquid from the liquid storage portion 2. Since the liquid is supplied to the liquid absorbing member 5 through the guide member 3 and is supplied to the marking surface 61 on which the liquid 8 supplied to the liquid absorbing member 5 comes into contact, the star-shaped image is converted into a water-color-changing sheet by the rotation of the roller 6. At the same time as it is formed on the surface, the porous layer of the water discoloring sheet becomes transparent and the color of the substrate surface appears as a print image. In addition, when the roller rotates, the air corresponding to the supplied amount of water is taken into the liquid storage unit 2 from the air hole, so that the liquid 8 is continuously supplied from the liquid storage unit 2 to the marking surface 61. A printed image can be formed without interruption.

In addition, when not in use, the roller 6 pressed against the elastic member 7 moves downward due to the marking surface 61 separating from the article 9 (water color changing sheet) upward, and the liquid absorbing member 5 moves downward due to its own weight. Move to. Therefore, since the marking surface 61 is separated from the lower end portion of the liquid absorbing member 5 and the upper end portion of the liquid absorbing member 5 is separated from the lower end portion of the liquid guiding member 3, the supply of the liquid 8 to the roller 6 (the marking surface 61) is stopped.
At this time, the liquid supply to the liquid absorbing member 5 is stopped, and the liquid amount that can be held by the liquid absorbing member 5 is not left unattended. Even if it is left as it is, leakage of the liquid 8 does not occur.

It is a principal part longitudinal cross-sectional view which shows one Example at the time of use of the roller type applicator of this invention. It is a principal part longitudinal cross-sectional view at the time of non-use of the roller-type applicator of FIG.
