Traditionally, the contents of caulking agents, etc. have been used to fill the voids that occur in the interior and exterior of buildings. Store the object in the storage section and press the storage section by operating the trigger to pour out the contents. A dispenser is used (for example, see Japanese Patent Application Laid-Open No. 115718/1983) ). This kind of dispenser has a direct feed on the rod for pressing the cartridge. A structure in which the triggers are connected and uses friction to transmit the power of the trigger to the rod. It is.

0003 By the way, such dispensers can be used as cooking utensils to dispense mayonnaise and cream. There have been attempts to dispense edible viscous substances such as reams, but the above-mentioned dispenser Due to the structure of the dispenser, a large amount of force is required for the dispensing operation, and the dispensing amount is not constant, making it difficult to accurately dispense. There is a new problem in that a fixed amount cannot be dispensed. And the contents are not cut well, Contents remain near the spout, which can clog the spout and become unsanitary. Issues such as this arise.

0004 This type of dispenser is primarily designed for industrial use. , all parts other than the cartridge are made of metal due to durability and other issues. For this reason, The Spencer itself is heavy and difficult to handle, and part of the pressing part (rod) comes off. As mentioned above, when used as cooking utensils, for example, If you try to use it near water, such as in a water tank, it will rust easily and be unsanitary. .

[0005] Therefore, in order to solve these problems, the applicant has developed a A manual adhesive tape that presses and dispenses the contents inside the storage compartment by operating a trigger. Focusing on the dispenser, a gear body provided coaxially with the support shaft of the trigger; a pawl member provided on the trigger that can engage and disengage from the gear body; and a pawl member provided on the trigger; An elastic member that presses in the direction of engagement with the body and a storage part that has a spout at the tip. A rod that can move backwards and engages with the gear body, and a front rod that can engage and disengage from the gear body. A stopper provided on the main body and a direction in which the stopper is engaged with the gear body. We have proposed a dispenser for viscous substances that consists of an elastic member that presses against the viscous substance.

[0006]

[Problem that the idea aims to solve]

In the dispenser for viscous substances proposed earlier, after dispensing the contents, etc. , the requirement is that the rod can be easily pulled back when replenishing or replacing the contents. There was hope. Therefore, the present invention was developed based on the above-mentioned dispenser for viscous substances. The problem was to ensure that the pawl member was removed from the gear body after the gear was released, and the above problem was solved. The purpose is to provide a viscous substance dispenser that solves the problems and improves convenience. do.

[0007]

[Means to solve the problem]

This invention was made in consideration of the above-mentioned problems, and the A manual adhesive dispenser that presses and dispenses the contents inside the storage compartment by operating a gur. A gear body provided coaxially with the spindle of the trigger, and a gear body provided on the gear body. A pawl member that can engage and disengage and is provided on the trigger, and the pawl member is engaged with the gear body. It has an elastic member that presses in the direction of and a rod that meshes with the gear body, and a main body that can mesh with and disengage from the gear body. a stopper provided on the gear body, and a stopper that is pressed in a direction to mesh with the gear body A viscous substance dispenser comprising: an elastic member; A viscous material comprising a guide that sometimes causes the claw member to separate from the gear body. The object of the present invention is to provide a dispenser for use in a computer to solve the above-mentioned problems.

[Effect]

The viscous substance dispenser of this invention has the above structure, and the trigger is operated. Then, the claw member provided on the trigger meshes with the gear body and transmits power. this As a result, the rod that meshes with the gear body moves forward, and the tip of the rod releases the contents inside the storage compartment. Press and pour. At this time, the stopper resists the elastic member and separates from the gear body. It is in a state where it can rotate in the direction, and the rotation of the gear body is not hindered.

[0009] When the trigger is then released, it returns to its original position. At this time, the The pawl member that moves with the gar slides on the guide, and this guide provides resistance against the elastic member. then rotates away from the gear body in the disengagement direction (releases the meshing state), and rotates the gear body. I won't let you. Also, when the trigger is released, the stopper pushes the gear body as it rotates toward the gear body, causing the stopper to rotate toward the gear body. Rotate this gear body in the opposite direction until it hits the valley between the parts. After that the stopper It hits the valley, that is, it meshes with the gear body, stopping reverse rotation. this tooth By rotating the car body in the opposite direction, the rod will be pulled back a little, allowing the contents on the spout side to return.

【Example】

Next, the present invention will be explained in detail based on the embodiments shown in FIGS. 1 to 4. Figure 1 1 is a cross-sectional view of a first embodiment of a viscous substance dispenser according to the present invention, and 1 is a main body. Section 2 is a storage section. The main body part 1 and the storage part 2 are made of resin, and especially the storage part 2 is made of transparent material. Molded from clear resin. In addition, the storage section 2 can be detachably attached to the main body section 1. It is attached. A trigger 4 is assembled in the grip part 3 so as to be able to swing freely around a support shaft 5. It's included. A spring 6 is provided at the rear center of the trigger 4. The end is in contact with the inner surface of the grip part 3, and is triggered by the restoring force of the spring 6. 4 is always biased to return to its original position.

[0011] On the other hand, the trigger 4 has a claw member 8 having a protrusion 7 at one end at a constant angle with respect to the support shaft 9. The gear body 10 is provided so as to be rotatable in degrees, and the gear body 10 connects the support shaft 5 at a corresponding position. It is located in the center. This gear body 10 is a large diameter gear coaxially provided on the support shaft 5. It is composed of two gears: a first gear 11 and a second gear 12 with a small diameter. In Figure 1 , assuming that the clockwise direction is the forward direction and the counterclockwise direction is the reverse direction, the claw member 8 has A force in the opposite direction is applied around the support shaft 9 by the elastic member 13, and this causes The protrusion 7 is pressed toward the first gear 11 and meshes with the first gear 11.

0012 At the rear end of the main body 1, a stopper 15 having a protrusion 14 at one end is attached to a support shaft 16. It is provided so that it can be rotated by a certain angle around the center. In addition, the stopper 15 is operated The operating section 17 protrudes from the main body section 1. . A force in the opposite direction is applied to the stopper 15 by the elastic member 18, and the stopper 15 is The portion 14 is adapted to mesh with the first gear 11. In this way, the pawl member 8 and the stopper 15 are engaged with the first gear 11. , transmits the power of the trigger 4 to the first gear 11 via the pawl member 8 (i.e., transmits the power of the trigger 4 to the first gear 11 via the pawl member 8 1 gear 11 in the opposite direction) and the trigger 4 returns to its original position. At this time, the first gear 11 is prevented from rotating in the opposite direction by the action of the stopper 15. ing.

[0013] In addition, in the main body 1, the first gear 1 is located near the first gear 11. A guide 19 is provided so as to be located between the guide 1 and the line of movement of the claw member 8. This guide 19 is one of the divided members of the grip part 3 (located on the upper front side in Figure 1). (not shown) and restricts the rotational movement of the claw member 8. Shown in Figure 3 At the point when the trigger 4 is released and begins to return to its original position, the trigger sliding contact with the upper surface of the claw member 8 that moves with the movement of 4 (in the direction of the arrow in FIG. 3); The claw member 8 is rotated to guide the protrusion 7 away from the first gear 11. . When the trigger 4 returns to its original position, the pawl member 8 is completely removed from the first gear 11. (the first gear 11 meshes with the stopper 15).

[0014] Furthermore, the main body 1 has a rack 20 that meshes with the second gear 12, and has a rack 20 at the tip. A rod 22 provided with a push-out plate 21 is provided within the storage portion 2 so as to be reciprocatable. ing. Further, a grip portion 23 is provided at the end opposite to the push-out plate 21. A lid member 25 having a spout 24 is attached to the storage section 2 . Stored in storage section 2 The cartridge 26 to be stored is a bag-like body made of a soft film material or the like, or a bag made of resin. It is a cylindrical body formed by low molding. In the opening 27 of the cartridge 26, For example, a sealing material 28 made of a material such as aluminum is pasted, and the sealing material 28 is made of a material such as aluminum. A perforation 29 is provided for pouring out the contents (see FIG. 2). The tip of the rod 22 is removable on the back side of the extrusion plate 21 in the drawing. Although the one shown is shaped so that it can be attached to the This extrusion is made so that the rod can be attached and detached, and the front and back surfaces are the same shape. By eliminating the directionality from the plate, the work of attaching the rod 22 and the extrusion plate 21 is made easier. It can be made simple.

[0015] Next, the operation of the viscous substance dispenser according to the present invention will be explained. First, when you grip the grip part 3 and pull the trigger 4, the trigger 4 resists the spring 6. The claw member 8 also moves together with the trigger 4. At this time, the claw member 8 is elastic. Since the member 13 presses the gear body 10 side, the claw member is removed from the guide 19. 8 begins to come off, this claw member 8 rotates toward the first gear 11 and the protrusion 7 engages the gear body 1. 0 (see Figure 4). When the trigger 4 is pulled, the pawl member 8 rotates in the opposite direction about the support shaft 9 and rotates to the first gear. 11, and rotates this first gear 11 in the opposite direction. At this time, the claw member 8 The protrusion 31 locks into the locking portion 30 of the trigger 4, and the claw member 8 rotates more than necessary. Position it so that it does not.

[0016] In this way, the pulling of the trigger 4 by the pawl member 8 causes the gear body 10 to rotate. The rotation of the gear body 10 is further transmitted to the rack 20, which moves the rod 22 forward. let At this time, the stopper 15 applies force in the direction of the gear body 10 by the elastic member 18. However, when the gear body 10 rotates in the opposite direction, , in the forward direction about the support shaft 16 against the elastic member 18 (the protrusion 14 from the gear body 10 Since the gear body 10 can be rotated in the detachment direction), rotation of the gear body 10 is not hindered. When the rod 22 moves forward, the pushing plate 21 presses the cartridge 26. Therefore, the contents are poured out from the perforation 29.

[0017] Next, when the trigger 4 is released, the force of the spring 6 causes the trigger 4 to open as shown in FIG. returns to its original position. At this time, the stopper 15 is pressed by the elastic member 18, so , the gear body 10 is slightly rotated in the forward direction and then stopped. That is, the first It becomes in mesh with the gear 11 of No. 1. As shown in FIG. 5, the first gear 11 has an inclined surface on the forward direction side of each tooth portion 32. (Slope on the side opposite to the rod sending rotation direction) From the slope of 32a, the slope on the opposite side (rod 32b is formed into a ratchet tooth with a gentle slope on the side in the delivery rotation direction. For example, the angle θ of the tooth portion 32 is set to about 50° to 70°. stop When the rotational drive in the opposite direction is no longer applied to the gear body 10, the stopper 15 is pressed. The tooth portion 32 is pushed by force, and the slope 32b, which is the gentle slope, touches the protrusion of the stopper 15. As described above, the first gear 11 slides against the portion 14 and contacts the valley portion 33. , it will rotate in the forward direction.

[0018] Rotation of the gear body 10 in the forward direction (i.e., rotation of the second gear 12 in the forward direction) , the rod 22 is slightly retracted, and the contents near the perforation 29 are transferred to the cartridge 26. However, the rod 22 does not move back thereafter. At this time, the claw member 8 is 19 and away from the first gear 11, and the trigger 4 returns to its original position. When the gear body 10 is rotated, the gear body 10 is not rotated. Trigger 4. Always equal by one operation. Since the gear body 10 rotates, by repeating this operation, a constant amount of content is always dispensed. Can be poured out.

[0019] Next, refilling and replacing the contents will be explained. After the rod 22 moves forward and finishes pouring out the contents, operate the stopper 15. 17 (rotate in the direction of the arrow in FIG. 1) to move the stopper 15 to the gear body 1. 0, then hold the grip part 23 at the rear end of the rod 22 and return it to the original position. Just pull it back. This is because the gear body 10 automatically stops when the stopper 15 is removed. This is because it is in a free rotation state.

[0020] To pour out the contents, a pouring hole 29 is opened in the cartridge 26 as in this embodiment. It is sufficient to just leave it in place, but it is also possible to attach a spout nozzle, etc. stomach. Moreover, the contents can be directly filled into the storage part 2 without using the cartridge 26, By sliding the extrusion plate 21 of the rod 22 airtightly on the inner wall of the storage section 2, the pouring It can be dispensed from the spout 24, but if the cartridge 26 is used, the contents cannot be exchanged. It is easy to replace, and it is necessary to consider the airtightness between the inner wall of the storage section 2 and the extrusion plate 21. There are benefits such as being eliminated.

[0021] The amount dispensed by one operation of the trigger 4 is determined by the diameter of the second gear 12. Even when the diameter of this second gear 12 is made smaller to reduce the feed amount of the rod 22, , the diameter of the first gear 11 that meshes with the claw member 8 and the stopper 13 is determined by the feed of the rod 22. It can be determined independently of the amount of water. Therefore, the first gear 11 is replaced by the second gear 1. 2, the distance from the support shaft 5 to the claw member 8 and the stopper 15 can be reduced. Since the distance can be increased, sufficient operating torque and rod locking force can be obtained. I can do that. Further, in the above embodiment, the claw member 8 and the stopper 15 mesh with the first gear 11, and the Since the rack 20 meshes with the gear 12 of No. 2 and the load is separated, it has sufficient strength. It is good because it can provide strength and durability, but it is not limited to this. The gear body is composed of one gear, and the pawl member, stopper, and rod are engaged with this gear. It is also possible to make it possible.

[0022]

[Effect of the idea]

As explained above, the viscous substance dispenser of the present invention has the above structure. Since a gear body is used as a means of transmitting the power of the trigger to the rod, the rod Compared to the method in which the rod is moved directly by the trigger, the rod changes when the trigger is operated once. The amount of movement is constant, allowing continuous and accurate quantitative discharge without the need for large force. It is Noh. Also, after operating the trigger, the stopper immediately stops the rotation of the gear body. The rod returns slightly to the front, and the contents near the spout are returned to the storage compartment, so the contents It cuts easily and prevents contents from remaining near the spout.

[0023] Also, if two gears are provided, one gear can be used with a pawl member, stopper, and rod. This prevents load concentration and further improves strength and durability. Also , Even if the gear that meshes with the rod has a small diameter, it will still mesh with the pawl member and stopper. By making one gear larger in diameter, it is possible to provide sufficient rotational torque. When the trigger is released, the pawl member is guided by the guide and away from the gear body. It is in a detached state, and the above-mentioned operation is performed to detach only the stopper from the gear body. The rod can be pulled out, making handling such as refilling or replacing the contents extremely easy. It becomes easy to do.
