  The conventional extrusion devices shown in Patent Document 1 and Patent Document 2 both move while rotating the roller by rotating a handle provided beside the roller, and it takes time to move the roller. . When you want to take out the material of multiple packages or want to push out the material remaining in the packaging container again, an operation to return the roller once moved to the opening of the package to the start position of extrusion occurs However, in the conventional extrusion device, since the time required for the roller return operation is the same as that for the extrusion operation, the work efficiency is very poor.

  Further, in the conventional extrusion device, the bottom plate of the box that accommodates the package is formed thin, and when the extrusion device and another container are placed on the same height stand, the discharge port for the object of the package is the other. It will be positioned lower than the container. For this reason, it is difficult to stably arrange the extrusion device and another container that receives the material extruded from the package, and it is necessary to lift and operate the extrusion device when performing extrusion. In particular, when extruding a large amount of material from a large package into another container with a height, operating the extrusion device by lifting it higher than the container will result in lack of stability of the device, spilling material, There was a risk of dropping the extrusion device, and there was a need for improvement.

  The present invention has been made in view of the above problems, and it is an object of the present invention to provide an extrusion device that is used to efficiently and reliably extrude a substance from a package that contains the substance in a flexible packaging container. It was made.

The invention of claim 1 relates to an extruding device used for extruding a substance from a package body in which the substance is stored in a flexible packaging container. The extrusion device according to the present invention includes a substantially rectangular fixing plate having a fixing tool for fixing one end of the packaging container at one end, a roller passing a predetermined height on the fixing plate, and a rear side of the roller. A handle connected to the central axis of the roller and a pair of horizontal plates provided on the left and right sides of the fixed plate and provided with guide grooves for defining the path of the central axis of the roller are provided. The guide grooves of the pair of horizontal plates are formed with a stop position above the fixture, and after rising from the stop position, the guide groove descends to reach the upper surface of one end of the packaging container fixed by the fixture, and the roller After reaching the region containing the substance of the packaging container and passing over the packaging container, it extends linearly at a certain height from the fixed plate, and the roller passes through the packaging container. Closed at the position. Further, in the extrusion device of the present invention, the fixing plate has a handle fixing member on the lower surface, and the handle is fixed to the handle fixing member by rotating the handle while accommodating the central axis of the roller in the stop position of the guide groove. It can be fixed .

  The roller of the extrusion device of the present invention can perform the operation of extruding the material of the package by pushing a handle disposed behind the roller, and is returned to the extrusion start position by pulling the handle. The movement operation of the roller of the present invention is easier than the operation performed by rotating the handle provided on the side surface of the conventional roller, and can move the roller more quickly. By operating this roller, it is possible to efficiently and quickly extrude a substance from the package fixed to the fixture.

  In the extrusion device of the present invention, the stop position is provided in the guide groove, and the guide groove is once lowered from the stop position and then lowered. Thereby, the center axis | shaft of the roller once accommodated in the stop position does not move from a stop position accidentally, but fixing and removal of a package can be performed efficiently.

  Furthermore, according to the present invention, the handle protruding rearward when in use can be accommodated on the lower surface of the fixed plate when not in use, and the extrusion device can be accommodated in a compact manner.

  The extrusion device of the present invention is provided with legs so that the height of the extrusion device is adjusted, and the position of the discharge port fixed to the extrusion device can be arranged at a preferred height with respect to the container that receives the substance. I made it. According to the present invention, even when a large amount of material contained in a large package is extruded and stored in another container having a height, both the extrusion device and the storage container are placed at the same height. It was possible to perform the extrusion operation stably and reliably in a stationary state.

A third aspect of the present invention, the fixed plate, characterized in that it comprises a cutting means on opposite other end to the one end portion with a fastener. By the cutting means, the other end of the package fixed to the fixture can be easily cut to provide a discharge port, and the operation of pushing out the substance from the discharge port can be efficiently advanced.

The invention of claim 4 relates to an extruding device used for extruding the substance from a packaging body containing the substance in a flexible packaging container. The packaging container applied to the extrusion device of the present invention is a substantially rectangular packaging container formed of a flexible material, and is provided with a fixing portion at one end, and is opposed to the side where the fixing portion is provided. A discharge portion that can be opened and used as a discharge port for a substance is provided at the center of the side, and the width of the packaging container is gradually narrowed toward the discharge portion. This extruding device is arranged at a substantially rectangular fixing plate provided at one end with a fixing tool for fixing one end of the packaging container, a roller passing a predetermined height on the fixing plate, and arranged behind the roller. A handle coupled to both ends of the central axis of the roller, and a pair of horizontal plates provided on the left and right of the fixed plate and provided with guide grooves for defining the path of the central axis of the roller. Yes. The guide groove of the horizontal plate of the extrusion device according to the present invention has a stop position formed above the fixture, and after being raised from the stop position, it is lowered and fixed on the upper surface of one end of the packaging container fixed by the fixture. Furthermore, the roller extends linearly from the fixed plate at a certain height while passing over the packaging container after reaching the region containing the substance of the packaging container.

  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a top view of the extrusion device 1 to which the packaging body 30 is fixed, and FIG. 2 shows a side view of the extrusion device 1. The extrusion device 1 includes a substantially rectangular fixed plate 2, a clip 4 fixed to the fixed plate 2, a roller 6, a handle 8, and a pair of horizontal plates 10 and 12 provided on the left and right sides of the fixed plate 2. I have.

  In the present embodiment, the central shaft of the roller 6 and the handle 8 are formed by a single bar-like member 14. The rod-shaped member 14 passes through the center of the roller 6, protrudes from both ends of the roller 6, and extends to the outside of the horizontal plates 10 and 12. Hereinafter, the portion of the rod-shaped member 14 that functions as the central axis of the roller 6 is referred to as a rod-shaped portion 14a.

  The shape of the part which functions as the handle | steering-wheel 8 of the rod-shaped member 14 is demonstrated still in detail. The handle portion of the handle 8 includes a rod-like portion 14b extending from the both ends of the rod-like portion 14a at an angle of approximately 90 degrees and extending rearward of the roller 6, and a rod-like portion 14c extending rearward while inclining inward from the end of the rod-like portion 14b. And a rod-shaped portion 14d extending rearward along the longitudinal central axis of the extrusion device, and a rod-shaped portion 14e forming a circular hole at the end of the rod-shaped portion 14d. As described above, the handle portion of the handle 8 is composed of the rod-like portions 14b to 14e obtained by bending the rod-like member 14, and has a symmetrical shape.

  The grip portion 16 is fixed to the rod-shaped portion 14d. When the grip portion 16 is pushed, the roller 6 moves forward, and the operation of pushing out the substance in the package 30 can be performed. The grip portion 16 is formed with a concave portion 18. By gripping the grip portion 16 with a thumb on the grip portion 16, the grip portion 16 can be easily held and pushed out with force.

  When the grip 16 is pulled rearward, the roller 6 is easily retracted. The backward movement operation of the roller 6 can be performed very quickly because no resistance is received from the substance in the package 30 as compared with the time of extrusion.

  The rod-shaped portion 14 a of the rod-shaped member 14 that functions as the central axis of the roller 6 passes through the guide groove 20 provided in the horizontal plates 10 and 12 and extends to the outside of the horizontal plates 10 and 12. As the rod-shaped portion 14 a moves in the guide groove 20, the roller 6 moves between the horizontal plate 10 and the horizontal plate 12 at a height determined by the guide groove 20. Since the height of the guide groove 20 is set to the most suitable height for the roller 6 to extrude the substance from the package 30 at a preferred height, the roller 6 can extrude the substance efficiently.

  The guide groove 20 is capable of holding the roller 6 so as not to hinder the movement of the operator when the roller 6 efficiently extrudes a substance from the package 30 and the package 30 is removed. Have a good height and shape. The height and shape of the guide groove 20 will be described in more detail.

  The guide groove 20 includes a stop position 22, a curved portion, and a straight portion. The stop position 22 is provided above the clip 4 and can store and hold the rod-shaped portion 14a therein. The guide groove 20 once rises in a circular arc shape from the stop position and then smoothly falls to reach the upper surface of one end portion of the packaging body 30 fixed by the clip 4, and a curved portion is formed at this portion. Yes.

  The extrusion device 1 of the present embodiment has a stop position 22 provided above the clip 4, so that the clip 4 and the roller placed at the stop position 22 even when the clip 4 is opened and closed when the package 30 is removed. 6 does not interfere and is very convenient. In addition, since the shape of the curved portion connected to the stop position 22 is configured to once rise and then drop, the roller 6 accommodated in the stop position 22 does not move from the stop position 22 by mistake, The packaging body 30 can be fixed and removed more efficiently.

  The linear portion of the guide groove 20 is started from a position corresponding to the upper surface of one end portion of the package body 30 and extends in a range in which the package body 30 passes over the region containing the substance. It is closed at a position that has passed through the package 30. The height of the guide groove 20 in the straight portion is constant so that the distance between the lower end of the roller 6 passing therethrough and the fixing plate 2 is substantially the same as the thickness of the packaging container of the packaging body 2. .

  When the height of the guide groove 20 defines the distance between the roller 6 and the fixing plate 2, when the roller 6 passes over the packaging body 30 in order from one end of the packaging body 30, the substance contained therein becomes the roller. 6 are pushed in order from one end, and all are pushed out without leaving the package 30. As a result, almost no substance remains in the package 30 after the roller 6 has passed.

  The rod-like portion 14a can freely rotate in the roller 6. Further, the rod-shaped portion 14d has a predetermined angle in the vertical direction with respect to the rod-shaped portion 14c. This angle is set so that the rod-shaped portion 14 d is parallel to the fixed plate 2 at a position higher than the roller 6 when the roller 6 is positioned on the packaging body 30. For this reason, when performing extrusion, the grip part 16 fixed to the rod-shaped part 14d can be maintained at a position higher than the roller 6 and parallel to the fixed plate 2. The operator can easily perform the push-out operation by applying force to the grip portion 16 during the push-out work.

  Moreover, since the rod-shaped part 14a can rotate in the roller 6, the operator can adjust the angle of the handle 8 according to a working state. For example, when the pushing device is arranged at a high position and the operator pushes out from a low position, pushing out is performed even when the grip portion 16 is supported at a slightly high position from the fixed plate 2. Is possible.

  The handle 8 can be rotated in the direction of A in FIG. 1 in a state where the rod-like portion 14 a is accommodated in the stop position 22. The rotated handle 8 is accommodated under the fixed plate 2. FIG. 3 shows a view of the extrusion device 1 in a state in which the handle 8 is accommodated under the fixed plate 2 as viewed from the rear. Here, the fact that the rod-shaped portion 14 d has a predetermined angle in the vertical direction with respect to the rod-shaped portion 14 c has a preferable effect even when the handle 8 is accommodated under the fixed plate 2. That is, when the rod-shaped portion 14a is accommodated in the stop position 22 and the handle 8 is rotated, the rod-shaped portion 14d and the rod-shaped portion 14c are parallel to the fixed plate 2 with the rod-shaped portion 14b and the rod-shaped portion 14c facing obliquely downward. The rod-shaped portion 14d and the grip portion 16 can be accommodated in a state along the lower surface of the fixed plate 2.

  A handle fixing member 24 is provided on the lower surface of the fixing plate 2 of the extrusion device 1, and the rod-like member 16 of the handle 8 can be fixed. The handle fixing member 24 in the present embodiment is formed of a pair of elastic members having a substantially semicircular cross section, and each member accommodates one rod-like portion 14d in a semicircular portion, whereby the handle 8 Is securely held. The push-out device 1 can be stored in a state in which the handle 8 is folded under the fixed plate 2 and miniaturized when not in use.

  When the handle 8 is folded under the fixed plate 2, the rod-like portion 14 e protrudes forward from the fixed plate 2. The extrusion device 1 can also be housed by being suspended on a wall surface or the like by a hole in the rod-like portion 14e.

  As shown in FIG. 3, the fixed plate 2 includes a pair of plate-like legs 26 and 28. The position of the discharge port of the package 30 placed on the fixing plate 2 is adjusted by the legs 26 and 28 so as to come to the position of the inlet of the container for containing the extruded material, and the material does not spill. Housed in a container.

  FIG. 4 schematically shows a state in which a substance is pushed out from the package 30 by the extrusion device 1 and transferred to the storage container 34. The packaging body 30 shown in FIG. 4 contains a large amount of substance in a large packaging container, and the substance pushed out from the packaging body 30 is transferred to a storage container 34 having a height. The height of the leg is adjusted so that the discharge port of the package 30 is higher than the entrance of the storage container 34, and the extrusion device 1 and the storage container 34 are placed on a stand having the same height. In this state, the extrusion operation can be carried out stably.

  Next, an aspect of the packaging container 40 that is preferably applied to the extrusion device 1 of the present embodiment will be described. The packaging container 40 is made of a flexible material such as synthetic resin, paper, or a material on which aluminum is vapor-deposited. The shape of the packaging container 40 is substantially rectangular. The packaging container 40 includes a fixing portion 42 for fixing to the clip 4 of the extrusion device 1 at the tip of one side of the substantially rectangular shape. A discharge portion 44 is provided on a side opposite to the side on which the fixing portion 42 is provided, and the substance is stored in the intermediate storage portion 46. A top view of the packaging container 40 is shown in FIG. 4, a side view is shown in FIG. 5, and a perspective view is shown in FIG.

  The fixing portion 42 is provided at the tip of the edge portion 41 on one specific side of the four closed sides of the packaging container 40, and the thickness thereof is larger than that of the edge portion 41. Since the fixing portion 42 has a thickness larger than that of the edge portion 41 and corresponds to the shape of the tip portion 5 of the clip 4, the fixing portion 42 is easily fixed by the clip 4. As shown in FIG. 7, once the clip 4 sandwiches the fixing portion 42 of the packaging container 40, the fixing portion 42 is fixed by the distal end portion 5 of the clip, so that the packaging container 40 does not come off unless the clip 4 is opened. . For this reason, even if it is a case where a substance is extruded from the inside of the packaging container 40 using the roller 6, there is no possibility that the packaging container 40 will come off from the clip 4, and extrusion can be performed efficiently.

  The discharge part 44 is provided on a side opposite to the side on which the fixing part 42 is provided. The length from the fixing portion 42 to the discharge portion 44 of the packaging container 40 is substantially equal to the length from the tip of the clip 4 fixed to the fixing plate 2 of the extrusion device 1 to the end portion of the fixing plate 2. When the fixing portion 42 is fixed with the clip 4, the discharge portion 44 reaches the end of the extrusion device 1. By opening the discharge part 44 and communicating with the accommodating part 46, a substance discharge port can be formed.

  In order to open easily the discharge part 44 of the packaging container 40, the cutting | disconnection means 32 can be provided in the edge part of the fixing plate of the extrusion apparatus 1. FIG. The cutting means 32 in the present embodiment is a saw blade provided at the end of the fixed plate 2.

  A packaging container 50 that is more suitably applied to an extrusion device using a roller will be described. The packaging container 50 is made of a flexible material equivalent to the packaging container 40. As shown in FIG. 8, the packaging container 50 has a polygonal shape. A fixing portion 52 for fixing to a clip of the extrusion device is provided on one side of the polygon, and a discharge portion 54 provided on a side opposite to the side on which the fixing portion 52 is provided is provided. An accommodating portion 56 is provided between the discharge portions 54. The packaging container 50 is formed in the vicinity of the discharge portion 54 such that the width of the storage portion 56 gradually decreases toward the discharge portion 54.

  As an aspect of the extrusion device corresponding to the packaging container 50, an extrusion device 60 is shown in FIG. In FIG. 10, the same number is attached | subjected about the thing which has the structure same as the extrusion apparatus 1. In FIG. The fixing plate 62 is formed so that the width around the other end facing the one end where the clip 4 is provided is gradually narrowed corresponding to the packaging container 50, and the cutting means 64 is provided in the packaging container at the other end. It has been.

  Since the width of the storage portion 56 is smoothly narrowed in the vicinity of the discharge portion 54, the packaging container 50 is smoothly pushed out without waste by the rollers 6 of the extrusion device.

  As mentioned above, although the specific example of this invention was described in detail in the Example, these are only illustrations and do not limit a claim. The technology described in the claims includes various modifications and changes of the specific examples illustrated above. For example, the shape of the recess of the handle of the extrusion device, the shape of the leg, and the shape of the cutting means can be changed within a range that does not impair the original function and effect of the present invention. Moreover, it can change also about the shape of the fixing | fixed part and cutting | disconnection part of a packaging container suitably applied to an extrusion apparatus.
