Description

Detailed Description of the Invention

  The present invention relates to a coating nozzle with an inner stopper to be attached to a discharge port of a caulking material filled in a tube or a cartridge type container.

  As a measure for preventing the hardening of the caulking material inside the coating nozzle to be attached to the discharge port, there is a measure for preventing the hardening by covering the container or the outer side of the coating nozzle with a cap or the like to block the outside air (Japanese Patent Laid-Open No. 9-255055). No. 2004-308119, JP-A-8-207944, JP-A-10-277471, Registered Utility Model No. 3084482), and a method of blocking the outside air by immersing the nozzle tip in a jelly-like substance (JP-A-9-234411), Some outlets with an inner stopper open and close the outlet by moving the outlet cap or the inner stopper back and forth (Japanese Utility Model Laid-Open No. 06-055454, Japanese Utility Model Laid-Open No. 62-58355, Japanese Utility Model Laid-Open No. 1-177156, Japanese Patent Laid-Open No. 2000-2000). -289765), and the tapered cap is plugged by the taper-shaped inner plug body coming into contact with the cylindrical cap. By cutting the dispensing unit is also one you want to use. (Japanese Patent Laid-Open No. 2006-224986)

  Some of the caulking material coating nozzles are covered with a cap, etc. to block out the outside air and cure measures have been taken, but by covering the coating nozzle with a cap etc., the curing time will be extended, but the cap etc. may fall off. In addition, there is a high risk of losing it in another location. As a pouring plug with an internal stopper (as disclosed in Japanese Utility Model Laid-Open No. 06-055454, Japanese Utility Model Laid-Open No. 1-177156, Japanese Patent Laid-Open No. 2000-289765), the pouring cap can be slid forward and backward in a fixed inner plug. It is formed so that the inner plug comes into contact with the inner plug and closes the spout, and (No. Sho 62-58355) makes the inner plug move forward and backward so that it comes into contact with and closes the spout. Is formed. In the tap with the above structure, the substance inside the container is not exposed to the outside air by discharging the inside of the outlet near the outlet and plugging it. Using as a spout for silicon caulking material has a very good advantage. However, the opening diameter of the pouring nozzle is fixed from the beginning, and the outer shape of the pouring outlet is dome-shaped, rectangular, or thick, but there is no hindrance to the function of plugging. For caulking work involving application work etc. by directly contacting nozzles with workpieces of various shapes such as corners, the outer shape of the spout is required to be suitable for application work in narrow places, and coking work is started. In doing so, it is required to observe the shape of the workpiece or the like, and cut the diameter and shape of the pouring nozzle opening most suitable for the caulking application work at that location. However, the proposed spout has a thin wall thickness, the size of the opening diameter, orthogonal cutting, inclined cutting, etc. In addition, the outer shape of the spout is not specified in the same way, and it is very inconvenient to use it as a coating nozzle in the above-described caulking work or the like. Further, the nozzle opening diameter of the nozzle cap proposed in (Japanese Patent Laid-Open No. 2006-224986) is determined from the beginning, as described above, and is not configured to change the diameter of the outlet opening.

  In general, caulking materials have various colors depending on the color tone of the building materials to be applied, and it is rare to use up one caulking material, so that the caulking material that has been interrupted is inevitably produced. Conventional tube or cartridge type When applying using a conical application nozzle attached to the discharge port of the caulking material filled in the container, even if the use is interrupted and the tip is immediately sealed with a tape with glue, etc. Curing starts from the point where the tip of the conical application nozzle is cut according to the purpose of use, the diameter of the spout opening becomes narrower, and the diameter of the spout opening increases as the base part is cut. In many cases, the shape of the spout opening of the application nozzle varies, so there is no appropriate stopper. The caulking material at the tip of the coating nozzle hardened in the meantime, so it was unavoidably sealed with a tape with glue, but this was not perfect, and in the summer when the outside temperature was high, the tip of the coating nozzle was about 24 hours. The caulking material hardens and solidifies. If the shape of the coating nozzle is cylindrical or widened, it can be easily extruded by pressing against the container even if it is solidified. The application nozzle has a tapered conical shape so that it can be used for cutting, so even if it is solidified about 3 mm from the tip or pressed against the caulking material cartridge container, it becomes conical from the tip to the base. If the hardened caulking material becomes an obstacle and the caulking material is not poured out as it is, the coating nozzle is removed from the caulking material container, and the wire shape from the tip of the coating nozzle Insert the object into the hardened part and extrude it in the direction opposite to the direction of pouring, remove the hardened caulking material from the part of the inlet of the coating nozzle, the nozzle base part where the small caulking material solidified at this time has not yet hardened All the caulking material in the coating nozzle must be removed in order to get lost in the nearby caulking material, and the caulking material adheres to the hand etc. due to the stickiness, and the adhering caulking material adheres to others. In order to prevent it, it must be wiped clean with tissue paper etc., and the work efficiency is remarkably bad.

The present invention has a risk of losing the above-mentioned cap of a conical application nozzle that is used by performing orthogonal cutting and inclined cutting according to work requirements with an arbitrary diameter such as a narrow or large diameter of a spout opening used for caulking work. In view of the problem of the conventional curing prevention measures for coating nozzles that cannot be reliably prevented from curing even if they are covered with a cap or sealed with a tape with glue, the operation after using the cut coating nozzle is also easy. At the same time, it aims to provide an excellent cure prevention measure.

Attached to the container outlet, materials with silicon caulking material does not adhere, a coating nozzle with plug in which is formed of a synthetic resin which is easily cut with a knife, and a lower mounting to the container outlet, external thread A cylindrical body having an intermediate portion having an annular protrusion on the outer periphery, a conical portion having a passage hole communicating with the cylindrical body on the lower outer periphery and having an inner plug on the upper portion. A fixed middle plug member erected on the upper end , a lower part having a female screw, a cylinder having an upper part having a sliding part in close contact with the annular protrusion on the inner periphery, and an upper part of the cylinder A movable nozzle member, which has a conical application nozzle with a conical surface close to the inner plug as its inner surface and a conical outer shape, can be slid forward and backward in a liquid-tight manner on the fixed inner plug member. The inner plug is provided with an annular groove for easy cutting means, Form the coating nozzle has a cut mark annular protrusion on the outer surface, and was constructed as a coating nozzle with plug in, characterized in that formed in the thickness of 5mm from 0.2 mm.

The inside plug was provided with a hollow part of a means for easy cutting, and was configured as a coating nozzle with an inner plug.

For example, silicon caulking material has a very sold in a convenient and where hardware store as caulking material, the coated nozzle are included, the lid or plug despite start immediately cured when opening not is included. As described above, it seems that one of the causes is that there is no appropriate stopper because the diameter and shape of the coating nozzle are various according to the purpose of use. The coating nozzle with an inner plug of the present invention is a conical coating nozzle that is used by narrowing or increasing the diameter of the spout opening portion and orthogonally cutting and tilting with a knife. This can prevent the caulking material inside the coating nozzle from hardening. In addition, since the cap and nozzle are integrated, the cap is not lost due to the method of covering the cap to prevent hardening, and the sealing is much higher than sealing with a tape with glue, making it more reliable. In addition to being able to prevent hardening, there is no need to expose the substance in the container to the outside air by discharging the injected substance in the vicinity of the spout with the inner plug and plugging it with the inner stopper with the above-mentioned inner stopper. By taking advantage of the excellent advantages of the stopper, a reliable preventive measure can be realized with a simple handling operation.

Since there is no troublesome removal cleaning, it is easy to start the operation again.

  Also, by cutting the entire length of the inner plug into a conical application nozzle outlet opening diameter and cutting it short, the distance that the caulking material passes through the narrow gap between the inner plug and the conical application nozzle is shortened. Although the applied force can be reduced, the cutting operation is facilitated by providing an annular groove that reduces the cutting cross-sectional area of the inner plug.

  In addition, when the caulking material is hardened inside the coating nozzle without forgetting to plug, the caulking material is hardened by separating the fixed plug member and the movable nozzle member by screwing and forcibly moving the movable nozzle member forward. It is very easy to remove the contents.

  Next, embodiments of the present invention will be described with reference to the drawings.

The application nozzle with an inner plug of the present invention is attached to the discharge port 4 of the container 1 and is provided with a fixed inner plug member 2 and a movable nozzle member 3, and the material is a synthetic resin and a silicon caulking material is not bonded, and a knife is simple. It is made of a material that is cut into pieces.

  The fixed plug member 2 shown in FIG. 2 is provided with a passage hole 8 in the lower part at the upper end of a cylinder 5 having a lower part attached to the discharge port 4 of the container 1 and a male screw 6 on the outer periphery of the middle part. A conical portion 10 provided with an inner plug 9 having a plurality of annular grooves 15 supported by the inner plug support column 24 is provided upright.

A movable nozzle member 3 shown in FIG. 1 and others has a conical application nozzle 14 at the upper end of a cylinder 13 provided with a female screw 11 in the lower part and a sliding part 12 in the upper inner periphery. The movable nozzle member 3 to the fixed inside plug member 2, and fitted so as to be forward and backward sliding in a liquid-tight manner, the outer shape of the conical application nozzle 14 forms a conical, and is easily cut like a knife 0 Form with a thickness of 2 mm to 5 mm .

The inside plug 9 may be provided with a plurality of annular grooves 15 as shown in FIG. 2 or the like as an easy cutting means, or may be provided with a hollow portion 16 as an easy cutting means as shown in FIGS. The tube or cartridge outlet 4 and the fixed plug member 2 may be integrally formed.

FIG. 1 shows a coating nozzle with an inner stopper attached to a tube or cartridge container before initial use. Next, a description will be given based on FIGS. The inner plug 9 and the conical application nozzle 14 are arranged in an arbitrary shape as shown in FIG. 3 and FIG. 5 according to the purpose of use. Open an orthogonal or inclined cut. At this time, when the portion near the tip of the conical application nozzle 14 is cut, the diameter of the spout opening becomes narrower as shown in FIG. 5, and becomes thicker as shown in FIG. 3 near the base of the conical application nozzle 14. Next, the fixed stopper member rotation preventing projection 18 is fixed with a finger, and the movable nozzle member 3 is screwed forward, and the thick wall portion 19 reaches the annular protrusion 20 so that it is difficult to expand due to the thick wall, and the screw advances forward. Stop screwing forward when is no longer easy. FIG. 4 is a diagram in which the above-mentioned screw advance is stopped.

  Next, when the tube or cartridge container filled with the caulking material is pressed, the caulking material discharged from the container discharge port passes through the cylindrical body 5, the passage hole 8 and the gap portion 21, and is poured from the spout opening 22. At this time, since the thick wall portion 19 is in a state of strongly tightening the annular protrusion 20 by the above-described screw advance, the back flow to the screw portion is prevented when the pressure in the gap portion 21 is increased, Further, wobbling of the movable nozzle member 3 is prevented, and then a caulking operation of the caulking material applied directly to the workpiece is performed.

When reverse threadedly work after the end of the movable nozzle member 3, the gap portion 21 and the inner plug cutting portion 23 and the spout opening leaving been caulking material 22 is the extruded simultaneously stopper. At the next use, the caulking work of the caulking material can be performed again by screwing the movable nozzle member 3 forward.

  Forgetting to tighten the stopper of the movable nozzle member 3 and disassembling when the caulking material is hardened inside the conical application nozzle, the thick wall portion 19 of the movable nozzle member 3 reaches the annular protrusion 20 and the screw advance is easy. When it disappears, it is forcibly screwed forward to separate the movable nozzle member 3 from the fixed inner plug member 2 and remove the caulking material inside the conical application nozzle.

The embodiment of the present invention has been described above, but the present invention is not limited to the illustrated one, and the outer shape of the conical application nozzle is not limited to the conical shape, and is formed with a thickness that can be easily cut with a knife. Even in a polygonal pyramid shape, the sliding movement of the movable nozzle member is not limited to screwing, but can be applied to linear sliding movement, and the pouring material is not limited to caulking material but can be applied with adhesive. is there.
