Description

  The present invention relates to a cartridge for a sealing gun used by being mounted on a sealing gun.

  In buildings such as houses and buildings, filling the joints and gaps (joints) between various members of the building such as cracks in the outer wall, between the window sash and glass, to give water tightness and air tightness, Sealing materials are used to provide functions such as bonding, heat insulation, sound insulation, vibration proofing, and electric insulation. The container of the sealing material is a cartridge that can be attached and replaced by a sealing gun that can be operated with one hand on site.

  A cartridge is generally a cylindrical body made of thick paper, synthetic resin, metal, etc., a nozzle body screwed into one end of the body, and the other end of the body closed to slide inside the body. And a bottom plate that is movably fitted (see, for example, FIG. 1 of Patent Document 1). FIG. 6 is a perspective view of a conventionally known sealing gun. The sealing gun 1 includes a cartridge housing portion 60 and an extruding means 70. The cartridge housing part 60 has a bowl shape with an open top so that the cartridge can be quickly attached and detached. The cartridge is pushed out of the sealing ring 1 into the body of the cartridge as the sealing material is poured out. The means 70 is inserted and fixed to the sealing gun 1.

  In such a cartridge in which the bottom plate slides in the body, the bottom plate serves as a part that closes the bottom as a part of the container and functions as a piston that pushes out the sealing material. In addition to the shearing stress due to the viscosity of the sealing material, a frictional force between the inner periphery of the body and the bottom plate is also applied, which requires a large pressing force. In addition, if the contact accuracy between the inner periphery of the fuselage and the bottom plate is low, the sealing material may leak out and stick, and there is a risk of having to discard it while leaving unused parts. It is necessary to manufacture high, and the cost becomes high. Furthermore, since the body requires a relatively high strength so as to withstand a large pressing force, it causes high accuracy and high cost. In order to solve these problems, a cartridge having a bellows-like body has been proposed (see, for example, Patent Document 2 or 3).

Japanese Patent Laid-Open No. 2003-267379, FIG. No. 6-6040 Utility Model Registration No. 3033839

  The cartridge of the type in which the bottom plate slides in the body including FIG. 1 of Patent Document 1 has a problem at the time of disposal in addition to the above problems. That is, in the cartridge of the type in which the bottom plate slides in the body, the volume occupied by the entire container does not change even after use. Furthermore, the trunk is relatively strong and difficult to crush. Therefore, when a large amount of used cartridges are generated at a work site where a large amount of sealing material is used, there is a problem in that the work is obstructed because the space is bulky and takes up space. Further, the bulkiness has been a problem at the time of disposal.

  In the cartridge having the bellows-like body including Patent Document 2 or 3, the cartridge can be crushed small after use, and the problem of bulky waste is solved. However, since the cartridge is not fixed to the sealing gun, the posture of the sealing gun during use is limited and the workability is poor. For example, in a ceiling ceiling operation, the ceiling gun is operated in a posture close to vertical. The operator needs to work with care so that the cartridge does not fall off the sealing gun. In particular, the work at a high place is not only inferior in workability but also has a heavy burden on the operator. Further, in order to improve workability, for example, when a dedicated sealing gun having a cylindrical cartridge housing portion as described in FIGS. 1 and 2 of Patent Document 3 is prepared, the cost increases. There is a problem. In addition, a plurality of types of sealing guns must be prepared at the work site, which is not only inferior in workability but also inconvenient to store and carry.

  Therefore, the present invention provides a cartridge for a sealing gun that can be used by being fixed to a general sealing gun having a saddle type cartridge housing portion, is inexpensive, and can be reduced in volume after use. With the goal.

As shown in FIG. 5, a portion S between the upper bottom wall 31 and the flange 50 in the nozzle mounting portion 20 is inserted into the notch 61a.

  Since a well-known sealing gun 1 is used, the details of the sealing gun 1 are omitted, but the configuration and operation will be briefly described. FIG. 6 is a perspective view of a conventionally known sealing gun. The sealing gun 1 is connected to a cartridge-shaped holding part 63 and a cartridge containing part 60 provided with a receiving part 61 having a notch 61a located at the front end of the holding part 63 and the rear end of the cartridge containing part 60. Further, there are provided an extruding plate 71 that is movable in the holding portion 63 in parallel in the front-rear direction, and an extruding means 70 having an extruding rod 72 that is fixed to a substantially central portion of the extruding plate 71.

  The extruding means 70 includes an extruding plate 71, an extruding rod 72, a trigger 73, a lock lever 74, and a spring 75. When the trigger 73 is pulled, the push rod 72 is configured to push the push plate 71 forward toward the receiving portion 61. The push rod 72 is locked by a lock lever 74 so as not to move backward. The lock lever 74 is supported by the spring 75 at a position where the push rod 72 is locked, that is, in a state where the lock lever 74 is inclined rearward. By pushing the lock lever 74 forward to the release position in a substantially vertical state, the push rod 72 can be moved backward.

  The sealing gun cartridge 101 is a cylindrical container enclosing a sealing material. The sealing material enclosed in the cartridge 101 is generally an amorphous material having high viscosity. For example, silicon, modified silicon, polysulfide, polyurethane, acrylic, acrylic urethane, synthetic rubber, styrene butadiene rubber And butyl rubber type.

  The cartridge 101 for the sealing gun is mounted on the sealing gun 1 as a cartridge 100 with a nozzle body in which the nozzle body 10 is attached to the upper bottom wall 31 of the cylindrical container. The procedure for mounting the sealing gun cartridge 100 to the sealing gun 1 is not limited as long as the effect of the present invention is achieved. For example, the procedure is as follows. In advance, the sealing gun 1 moves the push rod 72 backward by setting the lock lever 74 to the release position. The cartridge 100 for a sealing gun with a nozzle body to which the nozzle body 10 is attached is hung on an extrusion plate 71 by a hooking portion 40 provided on the lower bottom wall 32 of the cartridge so that the lower bottom wall 32 is brought into contact with the extrusion plate 71. In the state, it is accommodated in the holding part 63. Next, the trigger 73 is pulled, the cartridge 100 is moved forward, and the position is adjusted so that the nozzle body 10 and the flange 50 protrude from the notch 61 a of the receiving portion 61. At this time, the upper bottom wall 31 is in contact with the inner wall of the receiving portion 61, and the receiving portion 61 is inserted between the flange 50 and the upper bottom wall 31.

The shape of the bellows is not particularly limited as long as it can be expanded and contracted in the present embodiment, and may be a shape in which units connecting the upper and lower surfaces of two truncated cones are continuous as shown in FIG. Although not shown in the drawings, a screw shape in which irregularities are spirally formed may be used.

  The material of the cylindrical container is not particularly limited in this embodiment, but is preferably a thin synthetic resin. Examples of the synthetic resin include a polypropylene resin, a polyethylene terephthalate resin, a polyethylene resin, a polyamide resin, and a polyvinyl chloride resin, and these can be used alone or in a laminate of a plurality of types. The wall thickness is not particularly limited in the present embodiment, but is more preferably 0.1 to 0.5 mm. Especially preferably, it is 0.2-0.3 mm. Since the wall thickness can be made thinner than a cartridge of the type in which the bottom plate slides in the conventional body, the amount of resin used can be reduced and the cost can be reduced.

  The upper bottom wall 31 has a convex nozzle mounting portion 20 that also serves as a mounting port for the nozzle body 10 and a spout for a sealing material. The nozzle mounting portion 20 is provided with a communication hole communicating with the cylindrical container and serves as a sealing material outlet. A screw 21 is cut on the outer periphery of the nozzle mounting portion 20, and the nozzle body 10 can be attached by being screwed into a screw (not shown) cut on the inner peripheral surface of the nozzle body 10. Furthermore, the nozzle mounting portion 20 can also serve as a filling port for filling the sealing material. After the sealing material is filled and before the nozzle body 10 is attached, the nozzle attachment portion 20 is sealed with a tape, a stopper, a lid, a heat seal or the like.

  FIG. 5 is a view for explaining the structure of the latching portion. The lower bottom wall 32 has a latching portion 40 that latches the extruded plate 71. As shown in FIG. 5, the latching portion 40 has a claw portion 41 that makes the extruded plate 71 contact the lower bottom wall 32, and the extruded plate 71 is inserted between the lower bottom wall 32 and the claw portion 41. It is preferable. The latching portion 40 may be molded integrally with the cylindrical container, or a separate molded product may be attached to the lower bottom wall 32. The claw portion 41 is not limited to an L-shaped cross section as shown in FIG. Moreover, at least one claw portion 41 is sufficient, but more preferably, there are two claw portions 41 at opposing positions. In addition, since the extrusion rod 72 is being fixed to the extrusion plate 71 in the substantially center part, it is necessary to arrange | position the claw part 41 with the space 42 for allowing the extrusion rod 72 to pass through.

  After inserting the push-out plate 71 between the lower bottom wall 32 and the claw portion 41, the cartridge 100 is rotated by 90 ° so that the claw portion 41 faces upward, so that the cartridge 100 can be moved regardless of the posture of the sealing gun 1. It can be reliably fixed by the sealing gun 1, and more stable work can be performed.

  Although the shape of the front-end | tip part 11 of the nozzle body 10 is not specifically limited, Generally, it is a cone shape. Further, a screw (not shown) for screwing onto the cylindrical container is cut on the inner peripheral surface of the base portion 12. At the start of use, the distal end portion 11 is cut at a position corresponding to a desired dispensing amount to form an opening.

  The material of the nozzle body 10 is not particularly limited in the present embodiment, but is preferably a synthetic resin. Examples of the synthetic resin include polypropylene resin, polyethylene terephthalate resin, polyethylene resin, polyamide resin, and polyvinyl chloride resin. The wall thickness is not particularly limited in the present embodiment, but is more preferably 0.3 to 1.0 mm. Especially preferably, it is 0.5-0.7 mm.

  A flange 50 is provided on the outer periphery of the nozzle mounting portion 20 and between the nozzle body 10 and the upper bottom wall 31. The front portion of the cartridge 100 can be fixed to the sealing gun 1 by inserting the portion S between the upper bottom wall 31 and the flange 50 in the nozzle mounting portion 20 into the notch 61 a of the sealing gun 1. The width of the nozzle mounting portion 20 between the upper bottom wall 31 and the flange 50 is preferably Tmm or more and (T + 2) mm or less, where T is the thickness of the receiving portion 61 of the sealing gun to be mounted. . The thickness T of the receiving part 61 of the sealing gun is generally 5 to 17 mm.

  The material of the flange 50 is not particularly limited in the present embodiment, but is preferably a synthetic resin. Examples of the synthetic resin include polypropylene resin, polyethylene terephthalate resin, polyethylene resin, polyamide resin, and polyvinyl chloride resin. The wall thickness is not particularly limited in the present embodiment, but is more preferably 0.5 to 2.0 mm. Especially preferably, it is 1.0-1.5 mm. The size of the flange 50 is preferably such that at least a part of the flange 50 is larger than the notch 61 a of the sealing gun 1 and smaller than the outer periphery of the sealing gun 1. More preferably, it is larger than the notch 61a of the sealing gun 1 and smaller than the outer periphery of the body part 30 of the cartridge. The shape of the flange 50 is, for example, a circle, an ellipse, a square, a rectangle, or a polygon, and is not particularly limited in the present embodiment.

  In the first embodiment, the flange 50 is formed integrally with the nozzle body 10. Since the depth at which the nozzle body 10 is screwed to the nozzle mounting portion 20 of the cartridge can be adjusted, the width of the portion S between the upper bottom wall 31 and the flange 50 can be adjusted. As a result, the receiving portion 61 of the sealing gun can be sandwiched between the upper bottom wall 31 and the flange 50, so that the cartridge 100 can be securely fixed by the sealing gun 1. Further, the nozzle body 10 can be reused, whereas the cartridge 100 is used once. Therefore, it is more preferable that the amount of resin used in the cartridge 100 is small. In the first embodiment, by integrally forming the flange 50 on the nozzle body 10, the amount of resin used in the cartridge can be reduced, and as a result, the amount of resin discarded can be reduced.

  FIG. 3 is a side view of the sealing gun cartridge according to the second embodiment. The sealing gun cartridge 102 according to the second embodiment is a cylindrical container in which a sealing material is sealed as shown in FIG. 3, and the upper bottom wall of the cylindrical container as shown in FIGS.
