[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container filled with a viscous agent such as a caulking material used for achieving watertightness in construction or an adhesive for adhering panels in a prefab house.

[0002]

[Prior art]

 Conventionally, for example, a caulking material is provided with a bottom plate slidable inside the cylinder body such as a cartridge for a caulking gun described in Japanese Utility Model Publication No. 57-195475 and having a nozzle at the tip. It is filled in a container and is commercially available. When the caulking material is discharged from the container, a so-called cylindrical holding portion for holding the filling container, a trigger type lever, and an extruding rod for moving the bottom plate to the nozzle side by repetitive operation of the lever. A discharge device called a caulking gun is used.

[0003]

[Problems to be solved by the device]

 However, in the above-described filling container and caulking gun, when the caulking material in the filling container is used up, the caulking material cannot be injected into the empty filling container again, and therefore only the caulking gun is re-injected. Since it was used and the filling container was expensive, it was thrown away, so it is not possible to reduce the cost of construction, but it is also possible to save resources by recycling etc. and suppress the increase in the amount of waste. Significantly against the social situation.

Therefore, an object of the present invention is to provide a reusable filling container for a viscous agent such as caulking material.

[0005]

[Means for Solving the Problems]

 To achieve the above object, in a viscous agent-filled container according to the present invention, a bottom plate slidable inside the cylinder is provided inside the cylinder, and a discharge port is provided at a front end of the cylinder. A viscous agent-filled container used in a state of being attached to a discharge device having an extruding rod for advancing the bottom plate to the discharge port side, with a pulling means for retracting the advanced bottom plate, and A valve portion is provided at an end edge portion of the bottom plate on the side opposite to the discharge port, which keeps the bottom plate and the inner peripheral surface of the cylindrical body watertight when the bottom plate is retracted.

[0006] Specifically, in the drawing means, at least one cord for pulling the bottom plate is fixed to the bottom plate at one end thereof, and the cord has the other end most forwardly of the bottom plate. The length is such that at least the rear end of the cylindrical body is reached in this state. Then, a hook member hooked at the rear end of the tubular body is attached to the other end of the string. Also, when the above-mentioned two strings are provided, the strings escape the push-out rod in the vicinity of the edge portion of the bottom plate, and the strings of the tube body are located from a position opposite to the central axis of the bottom plate. It is extended toward the rear end.

For example, the bottom plate is provided with a housing part and a storage part surrounded by the housing part, and the housing part is provided with a through hole communicating with and connected to the storage part. The storage portion is provided with a take-up reel which is axially supported by the housing portion. Then, two cords are drawn into the storage portion through the through holes, and each cord is fastened at one end to each groove portion that is doubly provided side by side in the rotation axis direction of the take-up reel. It can be stored by being wound and wrapped.

[0008]

[Action]

 According to the viscous agent-filled container of the present invention, since the container is provided with the pulling means and the valve portion is provided at the edge portion of the bottom plate, the bottom plate advanced by the pushing rod of the discharge device. Can be retracted. Along with this retreating operation, a negative pressure is generated so that the viscous agent can be charged again into the empty viscous agent-filled container in which the space between the bottom plate and the bottom plate is kept watertight.

Since the pulling means has a string attached to the bottom plate, the structure is simple and the container can be easily manufactured, and the pulling means does not get in the way. Therefore, the conventional caulking gun can be directly used as a discharging device. can do. Also, the bottom plate can be retracted simply by pulling on the cord, which is very convenient.

Since the two cords are provided and are extended from the position facing the central axis of the bottom plate, the balance when pulling the cord is good and it is very easy to pull. ◆ Because the string can be stored in the storage part of the bottom plate, it is possible to prevent the string from hanging down from the rear end of the viscous agent-filled container by appropriately storing the string depending on the forward movement of the bottom plate. It is possible, and the string does not get in the way of work. -Since the take-up reel is provided in the storage section, the string can be easily wound up and stored by simply turning the take-up reel. ◆ Since each take-up reel is provided with a groove for each string, a plurality of strings can be taken up without being entangled in the storage section, so the take-up reel can rotate smoothly. Operability is improved.

Since the hook member is attached to the other end of the string, if the hook member is hooked to the rear end of the tubular body while being fully filled with the thickener, the bottom plate can move forward. Regardless of the situation, since the other end of the string always comes to the rear end of the container, the viscous agent can be quickly refilled in the container.

【Example】

 One embodiment of the thickener filling container (hereinafter, referred to as “filling container” at the end) according to the present invention is shown in FIGS. 1 to 9 and will be described below. Among them, FIG. 1 is a vertical sectional view showing a state where the bottom plate of the filling container in this embodiment is advanced, and FIG. 2 is a vertical sectional view showing a state where the bottom plate of the filling container is retracted. 3 is a vertical cross-sectional view of the bottom plate of the filling container, FIG. 4 is an exploded perspective view of the bottom plate of the filling container, and FIG. 5 is a partially enlarged cross-sectional view showing a valve portion of the bottom plate contacting the inner peripheral surface of the cylinder of the filling container. FIG. 6 is a perspective view of a main part showing the state where the bottom plate of the filling container is most retracted, FIG. 7 is a partially cutaway perspective view showing the state where the bottom plate of the filling container is advanced, and FIG. FIG. 9 is an overall perspective view showing an example of a discharge device for advancing a bottom plate of a filling container, and FIG.

As shown in FIG. 1 and FIG. 2, this filling container 1 is a container for filling a viscous fluid such as a caulking material or an adhesive, that is, a viscous agent 2, inside a cylindrical body. A bottom plate 20 slidable inside the tubular body 10 is provided inside the tubular body 10, and a front end of the tubular body 10 has a discharge port 11 for discharging the viscous agent 2 as the bottom plate 20 moves forward. As shown in (a), it is provided with a drawing means 30 for retracting the advanced bottom plate 20. Although the number of the pulling means 30 is not particularly limited, for example, two strings 31 and 32 are fixed to the bottom plate 20, and the strings 31 and 32 are indicated by arrows (b) in FIG. The bottom plate 20 is retracted by the pulling operation. With the retreat, the viscous agent 2 stored in another storage container (not shown) or the like is sucked from the discharge port 11, and the emptied cylindrical body 10 is filled with the viscous agent 2 again.

Here, the filling container 1 is used by being attached to a known discharging device 9 called a so-called caulking gun as shown in FIG. 8, for example. The discharge device 9 includes a semi-cylindrical holding part 90 for holding the filling container 1, an extruding rod 91 for advancing the bottom plate 20, a trigger type lever 92 for extruding the extruding rod 91, and a grip 93. It is configured. At the front end of the push rod 91, a disc 94 that abuts the bottom plate 20 is provided.

As shown in FIGS. 1 and 2, the cylindrical body 10 can be used for repeating forward and backward movements of the bottom plate 20 such as metal such as aluminum, resin such as plastic, and cardboard such as cardboard. Made of a material that can withstand. A nozzle portion 12 having a tapered shape and a closed front end is integrally provided at the front end thereof, and the discharge port 11 is opened by cutting off the front end. The ejection port 11 may be opened at the tip of the nozzle portion 12 in advance. A stopper portion 13 is provided at the rear end of the tubular body 10 so as to prevent the bottom plate 20 from coming off from the rear end of the tubular body 10 when the bottom plate 20 is retracted.

As shown in FIGS. 3 and 4, the bottom plate 20 is composed of a substantially bottomed cylindrical housing portion 21 made of resin or the like and a storage portion 22 surrounded by the housing portion 21. Furthermore, the housing portion 21 is formed by joining a front housing front portion 21A and a rear housing rear portion 21B together.

The housing front portion 21A is formed into a substantially bottomed tubular shape, and a cylindrical shaft rod 23 extending toward the housing rear portion 21B side is provided upright on the bottom portion 21a thereof. The housing rear portion 21B is formed in a substantially cylindrical shape, and an inward flange portion 24 that projects inward is provided at a rear end portion of the housing rear portion 21B. The inward flange portion 24 is designed so as not to touch the disc 94 of the discharge device 9. The inward flange portion 24 is provided with through holes 25, 25 through which the cords 31, 32 are inserted so as to be located on the opposite sides of the shaft rod 23. The shaft rod 23 has a length that does not project further rearward than the inward flange portion 24 in a state where the housing portion 21 is formed from the housing front portion 21A and the housing rear portion 21B.

Further, the front end edge and the rear end edge of the bottom plate 20 are respectively provided along the respective end edges when the bottom plate 20 advances and retreats, and the inner peripheral surfaces of the bottom plate 20 and the cylindrical body 10. Valves 26 and 27 are provided to keep and watertight. As shown in FIG. 5, the valve portion 27 (26) extends like a spatula from the housing rear portion 21B (housing front portion 21A) toward the inner peripheral surface of the tubular body 10. In order to prevent the valve portion 27 (26) from being caught when the bottom plate 20 slides, its tip portion 27a (26a) is formed so as to warp, and the abdominal portion 27b (26b) protruding most to the side is formed. It comes into contact with the cylindrical body 10. As a result, the bottom plate 20 and the tubular body 10 are kept watertight when the bottom plate 20 is moved forward and backward, so that the viscous agent 2 leaks to the rear side of the bottom plate 20 when moving forward, and a negative pressure is applied when moving backward. This prevents air from leaking into the cylindrical body 10.

As shown in FIGS. 3 and 4, the storage portion 22 accommodates the take-up reel 33, which is a component of the pulling means 30, together with the cords 31 and 32. The take-up reel 33 is axially supported with the shaft rod 23 as a rotation shaft by inserting the shaft rod 23 into a through hole 34 provided at the center thereof. A groove 28 is provided near the rear end of the shaft rod 23 penetrating the winding reel 33, and a retaining ring 35 for preventing the take-up reel 33 from coming off the shaft rod 23 is fitted into the groove 28. Has been done. At the rear end of the take-up reel 33, there is provided a recess 36 for accommodating the retaining ring 35 without protruding from the take-up reel 33.

The take-up reel 33 is provided with two groove portions 37 and 38 for winding the strings 31 and 32 side by side in the rotation axis direction (that is, the extending direction of the shaft rod 23). The ends of the strings 31 and 32 are fastened to the grooves 37 and 38, respectively. Therefore, by turning the take-up reel 33, the strings 31 and 32 are wound into the groove portions 37 and 38, respectively. Alternatively, only one groove may be provided and the strings 31 and 32 may be wound around the groove. Furthermore, at the rear end of the take-up reel 33, a recess 39 is provided at an appropriate position where the operator puts his finger on the tip of the finger so that the take-up reel 33 can be easily rotated.

As shown in FIG. 2, the length of the cords 31 and 32 is such that at least the other end reaches the rear end of the tubular body 10 when the bottom plate 20 is most advanced. Then, at the other end thereof, as shown in FIGS. 1, 3 and 4, a hook member 40 that is hooked to the rear end of the tubular body 10 is attached.

A method of handling the filling container 1 configured as described above will be described with reference to FIGS. 6 to 8. First, when the thickener 2 is discharged, the filling container 1 is sufficiently filled with the thickener 2 and the strings 31 and 32 are wound on the take-up reel 33 (see FIG. 6). Then, the hook members 40, 40 are hooked on the rear end of the cylindrical body 10. In this state, the pushing rod 91 of the discharging device 9 is set to the most retracted state (see FIG. 8), the filling container 1 is placed in the holding portion 90, and the semi-cylindrical lid 95 is closed. At this time, needless to say, when the ejection port 11 is not opened in the nozzle unit 12, the tip of the nozzle unit 12 is cut off in advance to open the ejection port 11. Then, the grip 93 is gripped, and the lever 92 is repeatedly operated to move the pushing rod 91 forward (see FIG. 7). By this operation, the bottom plate 20 of the filling container 1 is advanced and the viscous agent 2 is discharged from the discharge port 11. When the bottom plate 20 is in the most advanced state, the inside of the filling container 1 becomes empty.

At this time, since the disc 94 of the push-out rod 91 abuts only on the rear end of the take-up reel 33 and does not touch the inward flange portion 24 of the housing rear portion 21B, the disc 94 penetrates the disc 94. The holes 25, 25 are not blocked. Further, in order to reduce the friction caused by the rotation of the winding reel 33 with respect to the disc 94, a sliding material such as ethylene tetrafluoride resin is attached to the portion of the take-up reel 33 that contacts the disc 94. You can leave it. Then, as the bottom plate 20 moves forward, the take-up reel 33 smoothly rotates and sends out the strings 31 and 32.

When the viscous agent 2 is filled in the filling container 1 again, the lock mechanism (not shown) provided in the discharge device 9 for preventing the push-out rod 91 from retracting is released to release the push-out rod. 91 is most retracted, the lid 95 is opened, and the filling container 1 is taken out. Then, the hook members 40, 40 are removed from the rear end of the tubular body 10, and the discharge port 11 is inserted into the thickener stored in a large amount in another storage container or the like. In that state, when the strings 31 and 32 are pulled gently, the viscous agent 2 is sucked into the filling container 1 through the discharge port 11. When the strings 31 and 32 are pulled until the bottom plate 20 contacts the stopper portion 13 of the cylindrical body 10, the viscous agent 2 is sufficiently filled. After the filling is completed, the fingers are put in the recess 39 of the take-up reel 33 and the take-up reel 33 is rotated as shown by the arrow (c) in FIG. ) Is drawn toward the through holes 25, 25.

When attaching the filling container 1 to the discharge device 9 again, the hook member 40 is hooked on the rear end of the cylindrical body 10.

According to the above-described embodiment, the bottom plate 20 can be retracted by the cords 31 and 32, and the bottom plate 20 and the tubular body 10 are kept watertight by the valve portions 26 and 27. , 32 is pulled, a negative pressure is generated in the filling container 1, so that the viscous agent 2 is newly filled in the filling container 1 through the discharge port 11. Therefore, the filling container 1 can be reused without being discarded. Further, the conventional caulking gun can be used as it is as the discharging device 9.

The thickening agent 2 may be not only a caulking material but also an adhesive, and may be a toothpaste, mayonnaise or cream. If the filling container 1 is filled with an adhesive that joins the wooden panels of the prefabricated house and the above-mentioned discharge measure 9 is used, it is possible to easily apply the adhesive to high places where it was difficult to apply with a conventional brush or the like. You can Since the required amount of adhesive can be packed into the filling container 1 each time, it is possible to avoid inconveniences such as the remaining portion being cured and becoming unusable, which is very economical.

Further, since the two strings 31 and 32 are provided, the balance when pulling the strings 31 and 32 is good, and therefore it is very easy to pull and the usability is also very good. Furthermore, since the strings 31 and 32 are wound up and stored in the bottom plate 20 only by turning the winding reel 33, it is possible to prevent the strings 31 and 32 from hanging down from the rear end of the filling container 1, It doesn't get in the way of work. The winding operation is also easy. Since the strings 31 and 32 are wound around the individual groove portions 37 and 38, respectively, the strings are not entangled in the bottom plate 20, so that the take-up reel 33 rotates smoothly and the operability is improved. Since the hook member 40 is attached to the strings 31 and 32, if the hook member 40 is hooked at the rear end of the tubular body 10 at the start of the discharge operation of the viscous agent 2, it will always be performed after the tubular body 10. Since the strings 31 and 32 extend to the ends, the refilling of the thickener 2 can be performed quickly.

If the filling container 1 is provided with the bottom plate 20 that can be retracted by the pulling means 30, and the valve portions 26 and 27 that keep the cylinder 10 and the bottom plate 20 watertight, the filling container 1 of the above embodiment will be described. Needless to say, the shape, material, etc. may be changed in any way.

Further, the number of cords, the presence or absence of the hook member 40, the shape of the take-up reel 33, the pivotal support type of the take-up reel 33 with respect to the housing portion 21, and the like are not limited to those in the above-described embodiment, and any design is possible. You may change it.

Further, the take-up reel 33 is provided with a spring or the like for urging the take-up reel 33 to rotate so as to take up the strings 31 and 32, and when the take-up reels 31 and 32 are taken up, they are wound with fingers. You may make it unnecessary to rotate the take-up reel 33.

Furthermore, in the above-mentioned embodiment, the strings 31 and 32 are assumed to be wound up and stored on the take-up reel 33, but it goes without saying that they may not be windable. It does not have to be storable in the bottom plate 20.

Further, the pulling means 30 is not limited to the one in the above-described embodiment, but as in the modified example shown in FIG. 9, for example, a hook hole-like locking hole 80 is provided in the bottom plate 20, and this locking is performed. The bottom plate 20 may be retracted using a pull rod 82 having a locking projection 81 that is locked in the hole 80. In this case, the pull rod 82 is inserted from the rear end of the tubular body 10 as shown by the arrow (e), and the locking projection 81 is inserted into the large hole 80 a of the locking hole 80. Then, when the pulling rod 82 is rotated as shown by the arrow (f) to bring the locking projection 81 to the small hole 80b, the head 81a of the locking projection 81 does not come off from the small hole 80b. In this state, if the pull rod 82 is pulled as indicated by the arrow (g), the bottom plate 20 is retracted together with the pull rod 82. When attaching the filling container 1 to the discharge device 9, the pull rod 82 is removed. Here, the pulling rod 82 may also serve as the pushing rod 91 of the discharging device 9. In that case, the protrusion 94 may be provided on the disc 94 of the push-out rod 91.

The bottom plate can be retracted. Along with this retracting operation, a negative pressure is generated in the empty viscous agent filled container whose water-tightness is kept between the valve plate and the bottom plate. If it is inserted into the agent, the viscous agent is newly filled into the container through the discharge port. Therefore, the container can be reused without being thrown away, and it is possible to reduce costs, save resources, and reduce the amount of waste.
