Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a paste-like material pouring device for pouring out a paste-like material such as glue without spilling.

[0002]

[Prior art]

 FIG. 1 shows a conventional paste dispenser with a push rod 2 extending from a reservoir 1 to a barrel 3. A push plate 4 is fixed on the push rod 2 between the rear wall 11 of the storage part 1 and the rear wall 31 of the body part 3. A spring 5 is mounted around the push rod 2 between the push plate 4 and the rear wall 31 of the body 3. A pivotable locking plate 6 is arranged behind the rear wall 11 of the storage part 1 and another spring 7 is provided between said locking plate 6 and the rear wall 11 of the storage part 1. It is arranged. A trigger 8 is pivotally connected to the reservoir 1 under the push rod 2.

Referring to FIG. 2, by pushing the trigger 8, the push plate 4 is moved, and the push rod 2 positioned in the container 3 a loaded with the pasty material is moved forward. At this time, the locking plate 6 is pushed by the spring 7 and forms an angle θ with the push rod 2 so as to lock the push rod 2 and prevent it from being pulled backward. The trigger is further pulled, the push rod 2 advances, and the paste-like material is poured out from the tip of the loading container.

Please refer to FIG. When the push rod 2 is pushed to the end of the body, the user pushes the locking plate 6 toward the storage unit 1 with his thumb to eliminate the angle θ formed by the push rod 2 and the locking plate 6. Therefore, it is necessary to remove the locking force of the locking plate 6 to the push rod 2.

[0005]

[Problems to be solved by the device]

 With the configuration described above, the locking plate 6 acts so that the push rod 2 cannot be pulled out rearward, and cooperates with the push plate 4 only for pushing it forward. In this way, the paste-like material can be poured out from the body. However, in this conventional example, there is no buffer space between the push rod and the body, and due to the physical characteristics of the paste-like material. Under compression, there is often a return pressure in the barrel. If this return pressure is not released, the paste material is additionally squeezed out in an attempt to release the pressure, but this wastes the paste material. Therefore, it is an object of the present invention to provide a paste-like material pouring device in which the paste-like material does not drop unnecessarily.

[0006]

[Means for Solving the Problems]

 The paste-like product pouring device according to claim 1 comprises a push rod having a push disk at its tip located in a paste-like substance loading container which extends from the storage section to the body section and is disposed in the body section, and An elastic clip member mounted on the push rod between the rear wall and the rear wall of the body, and a push plate and a push spring attached around the push rod between the clip member and the rear wall of the storage unit. , A trigger that is pivotally connected to the storage section under the push rod, and when the trigger is pulled after the body is filled with the paste-like material, the push plate moves to push the pusher. In the pasty material dispensing device that can push the rod forward, the pinching action of the clip member allows the push rod to be pushed forward steadily, and when the push rod is pushed to the fixed position, Push the clip material further In addition, the push rod can be properly retracted in order to reduce the return pressure in the case of over-positioning and also in the case of overpressure in the barrel, which allows the paste It is possible to prevent pouring out too much or wasting it.

[0007]

[Embodiment of device]

 The invention will be best understood from the following description and the accompanying drawings. Hereinafter, a paste-like material dispensing device according to an embodiment of the present invention will be described with reference to FIGS. 4 to 7. Referring to FIG. 4, in the pasty material dispensing device of the present invention, the push rod 20 extends from the storage portion 12 to the body portion 10 and the push disk at the tip is positioned in the pasty material loading container. There is. An elastic clip member 50 is mounted on the push rod 20 between the rear wall 13 of the reservoir 12 and the rear wall 11 of the body 10. A push plate 30 and a push spring 40 are mounted around the push rod 20 between the clip member 50 and the rear wall 13 of the reservoir 12. A trigger 60 is pivotally connected to the reservoir 12 under the push rod 20 to form the structure shown in FIG.

Referring to FIG. 6, when the body 10 is filled with the paste-like material and then the trigger is pulled, the push plate 30 is moved to push the push rod 20 forward. At this time, the push disk 21 at the front end of the push rod 20 functions to squeeze the paste-like material out of the body 10. When the push rod 20 reaches the end of the body portion 10, the user needs to pull back the end portion of the push rod 20 with a force larger than the clamping force of the clip member 50. Then, as shown in FIG. 7, the push rod 20 can be easily pushed back to its original position.

By the sandwiching action of the elastic clip member 50, the push rod 20 can be stably pushed forward. The clip member 50 also serves to position the push rod 20 when the push rod is pressed into a fixed position. Furthermore, if an overpressure is created in the barrel 10, the push rod 20 can be properly retracted to reduce the return pressure, resulting in overdosing or wasted paste material. Can be prevented.

The embodiments described above are merely examples of the present invention, and the claims of the present invention should not be limited to these examples. All changes and modifications derived from this embodiment are within the scope of the present invention.

[0011]

[Effect of device]

 The pasty material dispensing device of the present invention is configured as described above, and the push rod can be stably pushed forward by the sandwiching action of the elastic clip member, and the push rod is moved to the fixed position. When pressed, the elastic clip member will also serve to position the push rod and, in the event of excess pressure on the barrel, reduce the return pressure so that the push rod is properly positioned. It can be retracted, which prevents the paste from being over-poured or wasted.
