Description

  The present invention relates to a ballpoint pen type adhesive.

  Examples of adhesives for paper that are currently in practical use include water-soluble glues such as starch, gum arabic, and water-soluble cellulose derivatives. Recently, an emulsion type paste using an acrylic resin having an adhesive mechanism different from that of these water-soluble pastes has appeared. These paper adhesives are filled in a container having a stick-like application body made of an open cell body such as sponge attached to the tip. When the application body is pressed against the paper surface during use, the built-in valve mechanism opens and the adhesive in the container is supplied to the application body to enable application, or the container is molded with a flexible material. In some cases, the container is pressed during use to reduce the internal volume, and the adhesive is applied to the coated body with the pressure.

  As described above, the adhesive having a stick-shaped application body made of sponge or the like is inconvenient because it requires some pre-operation such as strongly pressing the application body or pressing the container. In addition, since the tip area of the application body is large, these are suitable for applying the adhesive to a wide area, but are not suitable for accurately applying to a thin portion. For this reason, ball-point pen-type adhesives have attracted attention, but most have a structure that pushes the container even when the pen tip is a ball-point pen or presses the inside of the container by opening and closing the cap to extrude the adhesive. However, there is an inconvenience that the adhesive does not come out unless the pressure is first applied, and excessive adhesive is suddenly produced when pressed, or the adhesive is not sufficient when the pressure is lowered.

  Therefore, the ball-point pen type adhesive tool of the present invention is such that a rotary application body corresponding to a ball-point pen ball is rotatably held on a chip connected to an adhesive tank, and is structurally identical to the ball-point pen. is there. And an adhesive can be apply | coated by rotating a rotation application body on the paper surface, without opening and closing of a cap or a cap.

Such a ball-point pen type adhesive has a small gap between the tip opening of the chip and the rotary application body, so when left after use, the adhesive in which the gap between the tip opening of the chip and the rotation application body is solidified and reused. Furthermore, there is a problem that the rotary application body does not rotate and cannot be applied. In order to solve this problem, Japanese Patent Application Laid-Open No. 2000-85298 (see Patent Document 1) has a ball-shaped rotary application body rotatably held by a chip connected to the tip of an adhesive tank. In the adhesive that is supplied and applied to the rotary application body with the adhesive filled in the rotary application body, when not in use, the rotary application body is repelled by a spring and comes into contact with the inward tip edge of the chip for sealing. Thus, an applicator has been devised that can be applied smoothly even when it is reused after being left unattended.
However, in this case, in order to secure the seal, it is necessary to increase the strength of the spring, and it is necessary to strongly press against the object when applying. Also, since the inner surface of the chip is not a perfect circle but has a gap with the ball, the adhesive may dry out at the pen tip after standing for a long period of time, and the adhesive may not come out smoothly.

  Also, in recent years, in ballpoint pens filled with gel ink, an elastic body is loaded in the cap, and the pen tip is sealed to prevent moisture from evaporating from the tip of the pen. In many cases, the adhesive can be started to write, but in the case of an adhesive with a high solid content, even if a slight amount of water evaporates from the nib, it solidifies at the nib and the adhesive does not come out smoothly.

  Therefore, the present invention can be used immediately without extra operations such as pressing the container, opening and closing the cap and pressurizing, and can apply the adhesive in the required amount freely in small areas and large areas, Furthermore, it aims at providing the adhesive tool which can apply | coat an adhesive agent smoothly without leaving trial writing after leaving it for a long period of time.

  In order to achieve such an object, the present invention provides a ball-shaped rotary application body rotatably connected to a tip connected to the tip of an adhesive tank, and the adhesive filled in the adhesive tank is applied by rotary application. When the adhesive is supplied and applied to the body, when not in use, the rotating application body is repelled by a spring and sealed in contact with the inward tip edge of the chip. A refill which is an insoluble sticky resin emulsion and in which a grease-like backflow preventive agent is disposed on the tail end side of the adhesive is constituted, and the entire refill is loaded into an airtight container.

  The present invention also provides a ball-shaped rotary application body that is connected to the tip of an adhesive tank and is rotatably held by a chip, and the adhesive filled in the adhesive tank is supplied to the rotary application body for application. When the adhesive is not used, the rotary application body is sealed with an elastic body loaded in a cap, and the adhesive is a water-insoluble adhesive resin emulsion, and the adhesive tail A refill having a grease-like backflow preventing agent disposed on the end side is formed, and the entire refill is loaded into an airtight container.

  Further, since the adhesive does not solidify with the pen tip for a long period of time, an anti-drying agent having a composition richer in moisture than the adhesive is loaded into an airtight container so that the container is filled with water. In addition, it is more preferable that the vapor pressure of the anti-drying agent is higher than the vapor pressure of the adhesive.

  In addition, polypropylene or polyethylene having a low moisture permeation is used for the container.

  As described above, according to the present invention, the ball-shaped rotary application body is rotatably held by the chip connected to the tip of the adhesive tank, and the adhesive filled in the adhesive tank is used as the rotary application body. In the adhesive that is supplied and applied, the rotary application body is repelled by a spring and sealed in contact with the inward tip edge of the chip, or when the cap is set, the pen is applied by an elastic body loaded in the cap. The tip is sealed, and the refill is loaded into an airtight main body container, and a dry desiccant richer in moisture than the adhesive is placed in the airtight container, and the adhesive is insoluble in water. The grease-like backflow preventive agent 7 is disposed on the tail end side of the adhesive, and the container is pressed during use or pressurized by opening and closing the cap. Extra operation It can be used immediately even if it is not necessary, and it can be applied as much as necessary in small areas and large areas, and it can be applied smoothly without trial writing after standing for a long time. It can be an adhesive.

  Embodiments of the present invention will be specifically described below with reference to the drawings. Figure 1 shows the first embodiment. In FIG. 1, an adhesive tank 1 is a cylindrical body formed of a transparent synthetic resin, and a chip 2 is connected to the tip of the adhesive tank 1 through a tip plug 5. The tip 2 is formed into a bullet shape with stainless steel, and a rotary application body 3 having an outer diameter of, for example, 0.8 mmφ is held at the tip opening of the tip 2 in a state where a part thereof protrudes. ing. A spring 4 having an antenna-like tip is built in the chip 2, and the rotary application body 3 is ejected by the antenna-like tip of the spring 4 and is in contact with the inward leading edge 21 of the chip 2. . That is, the rotary applicator 3 and the inward leading edge 21 of the chip 2 constitute a valve mechanism, which is closed when not in use.

  The adhesive tank 1 is filled with an adhesive 6 to be described later, and a grease-like backflow preventing agent that can move forward as the adhesive is consumed without adhering to the tank wall on the tail end side of the adhesive 6 7 is arranged. Therefore, the atmospheric pressure in the direction of the adhesive 6 is applied to the backflow preventing agent 7.

  Thus, when the rotary applicator 3 is pressed onto the paper surface, the rotary applicator 3 moves backward against the elastic force of the spring 4 and the valve mechanism is opened. When the rotary application body 3 is rotated in the manner of writing with a ballpoint pen, the adhesive 6 in the adhesive tank 1 is immediately supplied to the rotary application body 3 and applied onto the paper surface as the rotary application body 3 rotates. However, since one of them is a ball-point pen type that is filled with an adhesive in a tank released to atmospheric pressure, it can be used immediately at atmospheric pressure without any extra pressure operation, and it is accurate even on thin parts. An adhesive can be applied. When the adhesive 6 is consumed and reduced, the backflow preventing agent 7 advances accordingly.

  In this refill state, the adhesive does not harden at the pen tip when left for about one week, but is loaded into an airtight container so that moisture does not evaporate from the pen tip seal portion even when stored without being used for a long time. In this case, the moisture of the adhesive fills the container through the wall surface of the refill tank.

  Furthermore, in order to fill the container with moisture, the container is loaded with the anti-drying agent 11 having a higher moisture content than the adhesive. This reduces moisture drying at the nib and increases long-term storage. The anti-drying agent 11 may be impregnated with a cotton-like substance, or may be filled with a gelling agent or the like so that the fluidity is lost.

  In this way, since the evaporation of moisture at the nib affects the storage stability of the product, it is preferable that the material of the container in which the refill is loaded has low moisture permeation, but considering the quality such as economy and strength, polypropylene Or polyethylene is suitable.

  Next, a second embodiment is shown in FIG. In FIG. 2, an elastic body 12 is loaded in the cap 8 instead of the spring of the first embodiment shown in FIG. 1, and when the cap 8 is tightened, the pen nib 2 sinks into the nib seal elastic body 12. Sealed. In this case, in order to prevent the backflow of the adhesive 6, it is safe to load the backflow prevention balls 13 in the lower part of the pen tip 2. In this case as well, the nib is sealed with an elastic body, but in order not to harden with the nib for a long time, the refill is loaded in an airtight container so that the nib does not dry due to moisture from its own tank. To.

  Furthermore, it is appropriate to load the drying inhibitor 11 into the container or to use polypropylene or polyethylene as the container material.

The adhesive 6 is an adhesive resin emulsion that is insoluble in water, and is a highly fluid liquid. Therefore, it is smoothly discharged and applied as the rotary application body 3 rotates. Further, even if left for a long time after use, the valve mechanism consisting of the rotary application body 3 and the inward leading edge 21 of the chip 2 is closed or sealed by the elastic body 12 and is caused by its own moisture in the airtight container. Further, drying at the pen tip is reduced by the moisture of the drying inhibitor, and the adhesive 6 is smoothly discharged from the tip of the chip 2 at the time of reuse.
(Example 1)

As the adhesive, Okitsumo Co., Ltd. No. 7790 (blue) and viscosity of 30 mPa · s were used. When the adhesive 6 is filled in the adhesive tank 1 in accordance with FIG. 1 and a refill is prepared and applied onto the paper surface, the container is discharged smoothly from the tip of the chip 2 without particularly pressing or pressing the container. The adhesive 6 could be accurately applied to the part. Further, 0.2 g of a drying inhibitor comprising a composition of 10% ethylene glycol and 90% water in a polypropylene container is filled in the core, loaded with a refill in a polypropylene container, and stored in a 50 ° C. constant temperature bath. Although applied after a month, it was applied without any problems.
(Example 2)
The refill and the drying inhibitor of Example 1 were stored in a thermostatic bath at 50 ° C. in the configuration shown in FIG. 2 and applied after one month.
(Example 3)
When the composition of Example 1 was used, the anti-drying agent was removed and the sample was stored in a thermostatic bath at 50 ° C. and applied after 1 month.
Example 4
When the composition of Example 2 was used, except for the drying inhibitor, it was stored in a constant temperature bath at 50 ° C. and applied after 1 month.
(Comparative Example 1)
When the refill of Example 1 was stored as it was in a constant temperature bath at 50 ° C., about 50% had no adhesive, and the remaining 50% had poor outflow.

It is sectional drawing of 1st Example of this invention. It is sectional drawing of 2nd Example of this invention.
