Description

  The present invention relates to a powder-filled bag that can be filled with various powders and granules and discharged at a desired location.

  In general, when performing various outdoor sports in various athletic competitions, athletic events such as schools, athletic festivals, athletics, etc., draw a white line of slaked lime with a line car (drawing tool) on the ground according to each sports. ing.

  This slaked lime is a strongly alkaline powder, filled in a bag made of paper or resin sheet that cannot be easily broken, and the opening at the upper end of the bag is sewn with a thread and sealed.

  And when drawing a white line on the ground, remove the thread at the top opening of the bag containing slaked lime, open the bag, turn it upside down, and point the open opening to the line car's receiving port. Slaked lime is put in the line car by dropping.

  However, as described above, when a bag containing slaked lime is turned upside down and put into a line car, the opening of the bag is not necessarily inserted into the line car well, and the bag is full of slaked lime. Because it is sometimes heavy, if the paper bag is turned upside down, the opening of the paper bag is not yet inserted into the receptacle, but slaked lime immediately comes out of the bag due to its own weight.

  Therefore, there is a problem that slaked lime scatters around between the receptacle and the opening of the bag, and there is a danger if you inhale strong alkaline slaked lime, touch the skin, or get into your eyes There was concern to give.

  In addition, as a reference document regarding the present invention, there is, for example, Patent Document 1 that discloses a packaging bag filled with powder. The bag disclosed in this document is provided with a filling port on the lower end side of the bag and a zipper for resealing near the upper end. And after filling the powder from the filling port on the lower end side, the lower end of this filling port is heat-sealed. When taking out the powder from the bag, the portion above the zipper is cut out to take out the powder, and the zipper is closed so that it can be resealed.

  However, in the case of this bag as well, the opening on the lower end side that is opened is configured to be completely sealed by heat seal bonding after filling the powder, and when taking out the powder, it will be taken out from the upper end opening, When this bag is used as a bag filled with slaked lime, it has the bag problem as described above, and the concern cannot be wiped out.

  The present invention has been developed in view of the above points. The purpose of this is to insert the closed bottom side of the bag into the desired location for supplying the granules, and to easily open the bottom, so that the granules filled in the bag are scattered around. An object of the present invention is to provide a powder-filled bag that is prevented as much as possible and can be supplied safely and reliably to a desired location.

  In order to effectively achieve the object as described above, the present invention has the following configuration. That is, the present invention comprises a bag body for filling a granular material having a bottom opening that can be opened and closed, and a string that temporarily closes and closes the bottom opening to provide a tip portion outside the bag body. It is a granular material filling bag characterized in that the bottom opening can be opened by releasing the temporarily closed closure of the bottom opening by picking and pulling the tip of the string.

  In the powder-filled bag of the present invention having the above-described configuration, when discharging the powder filled in the bag body at a desired location, the bag body is lifted and the bottom portion is placed in the desired location or in a desired location. By pulling the tip of the cord placed outside the bag body, the bottom opening that was closed at the rear of the cord is opened and the powder is discharged by its own weight. In the case of smoke, it can be easily supplied to the desired place with minimal scattering to the surroundings, and even in the case of granules, it can be prevented from scattering to the surroundings as much as powder. . Therefore, it is possible to prevent the worker from sucking powder that scatters around like smoke, and to discharge safely from the bag body, and even if particles are scattered around Since the amount is extremely small, the collection operation can be easily performed in a short time.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 to 3 are diagrams relating to a powder-filled bag according to the present invention, FIG. 1 is a perspective view of an example of a powder-filled bag according to the present invention, and FIG. 2 is a powder filled with the powder. FIG. 3 is an explanatory view when discharging the granular material from the body filling bag, and FIG. 3 is an explanatory view of a cross section of the granular material filling bag filled with the granular material.

  The powder-filled bag 1 is composed of a bag body 2, a string 3 and a ring 4. The bag body 2 is formed of a synthetic resin sheet such as polyvinyl chloride, polyethylene, polystyrene, or paper into a square tube having an appropriate size, and the upper opening 5 is sealed and the bottom opening 6 can be opened and closed. Is.

  That is, folds 7 are formed at a plurality of locations as shown in the bottom 2a of the bag body 2 so as to be folded inwardly in a triangular cross section. In addition, a plurality of holes 9 are formed in a row at regular intervals on the lower end piece 8 of the long side facing the bottom 2a. By folding the bottom portion 2a inward along each fold line 7, the opposite lower end piece portions 8 come into contact with each other so that the holes 9 of the lower end piece portions 8 are aligned with each other, and the bag body 2 is placed outside the bottom portion 2a. A recess 10 (FIG. 3) having a triangular triangular cross section is formed.

  In this example, the upper part 2b of the bag body 2 is formed by forming an upper edge 11a of both side surfaces 11 in an arc shape, and covering the upper surface part 12 on the front and rear sides along the upper edge 11a and bonding them. The upper end piece 13 is brought into contact with and bonded to close the upper opening 5. Both upper end pieces 13 are provided with elongated holes 14 so that the bag body 2 can be held by inserting a finger.

  A hole 15 for inserting the string 3 is provided at the end of the upper surface 12 of the bag body 2 near the upper end piece 13. Of course, this hole 15 may be provided at another location on the upper side of the bag body 2.

  The strings 3 inserted into the bag body 2 from the holes 15 are alternately inserted into the holes 9 of the lower end pieces 8 of the bottom 2a and sewn, thereby closing the lower end pieces 8.
