Description

  The present invention relates to a chopped strand filling body and a package thereof, a method of manufacturing a chopped strand filling body, and a method of manufacturing a chopped strand packing body.

  BACKGROUND ART Conventionally, as a package of chopped strands such as glass containing water, a package in which a flexible container is directly filled with chopped strands is known (for example, see Patent Document 1).

  Alternatively, a package is known in which a plurality of bags filled with the chopped strands are stored in a container. In addition, a bag used at this time is generally a so-called flat bag that has a rectangular shape in a flat state (for example, see Patent Document 2).

JP-A-62-182086 JP 2005-119673 A

  Of the two types of packing described above, the latter type, that is, once filling a plurality of bags with the chopped strands to be filled, and then storing the plurality of bags in a container, filling is performed. Since the volume per unit can be made relatively small, as described above, when the filler is a glass-containing chopped strand, the movement of moisture is relatively small, and as a result, the variation in the water content of the chopped strand is reduced. It has the advantage of being small.

  However, when the bag has the above-described shape (rectangular shape), the following problem may occur.

  That is, as shown in FIG. 13, when a flat bag 101 having a rectangular shape in a flat state is filled with a chopped strand 2 made of glass containing a predetermined amount of water, the flat bag 101 is chopped to a corner 103 of a bottom 102 of the flat bag 101. Since the strand 2 is filled without leakage, when the opening 104 of the flat bag 101 is closed, a portion corresponding to the corner 106 of the filling body 105 has a protruding shape (FIG. 14). When the packing bodies 105 having such a shape are stacked in a flat manner (a mode in which the bottom portions 102 of the flat bags 101 are stacked so as to be directed in the horizontal direction. The same applies in the present specification), the center of gravity and the shape of the packing bodies 105 are set. Is not stable, it is difficult to maintain a constant posture when a plurality of fillers 105 are stacked. Therefore, there is no other choice but to use a highly rigid container such as a metal grid-shaped container for packing (housing) the filling body 105, which raises a problem that the cost required for packing and transport increases. In addition, when the filling body 105 has an irregular shape as described above, it is difficult to efficiently load the filling body 105 in a container having a predetermined volume, and so-called close-packing cannot be performed. Because it creates a lot of space). Therefore, this also contributes to a rise in transportation cost.

  In view of the above circumstances, in the present specification, it is a technical problem to be solved by the present invention to pack chopped strand packing at lower cost than in the past.

  The solution to the above technical problem is achieved by the chopped strand packing according to the present invention. That is, this filling body is a chopped strand filling body in which a chopped strand of glass, a bag having a bottom at one end and a bag having an opening at the other end, and a chopped strand filled in the bag, On the bottom side, there is provided an inner width reduction portion in which the inner width dimension of the bag decreases as approaching the bottom portion, the bag is filled with chopped strands, and the opening side is squeezed and closed, and the bottom side is closed. In addition, a first outer width reducing portion is formed in which the outer width dimension is reduced as approaching the bottom, and the outer width dimension is reduced closer to the opening than the first outer width reducing portion, closer to the opening. It is characterized by the point that two outer width reductions are formed. Here, the “inner width” means the width dimension of the inner surface of the bag, and the “outer width” means the width dimension of the outer surface of the bag or the chopped strand filling. The “width direction” means the longitudinal direction of the opening when the bag is developed in a plane.

  Thus, in the present invention, the bag provided with the inner width reduction portion on the bottom side is filled with the chopped strand of glass, and the first outer width reduction portion is provided on the bottom side of the filler, and The second outer width reducing portion was provided on the opening side than the outer width reducing portion. With such a shape, the chopped strand filling body has a symmetrical shape on the side of the opening and the side of the bottom as compared with the related art. Thus, for example, when the filling body is placed in a flat posture, the position of the center of gravity of the filling body is stabilized at the central portion, and the shape is not easily collapsed at the time of placing. In addition, even when the filling body is placed with its bottom facing downward and the opening facing upward, the position of the center of gravity of the filling body is stable, and the shape does not easily collapse during placement. Therefore, a box-shaped packing member such as a container can be simplified or omitted, and thereby the cost required for packing can be significantly reduced.

  In the chopped strand packing according to the present invention, the water content of the chopped strand of glass may be 1% by mass or more and 13% by mass or less.

  In this way, by using glass chopped strands with a constant moisture content as filling material, compared to dry chopped strands, the chopped strands can be filled without leakage (without gaps) up to the bottom of the bag and the reduced inner width part can do. Therefore, the above-described operation and effect can be surely received. The reason for limiting the water content to the above-mentioned range is that when the water content is less than 1% by mass, the time required for white water to sufficiently penetrate into the chopped strand during papermaking becomes longer, and the filament is opened to a monofilament. This is because the longer the time required for the process, the higher the risk of lowering the production efficiency. On the other hand, when the water content exceeds 13% by mass, not only the improvement of the opening property at the time of papermaking is not expected, but also the possibility that the chopped strand adheres to the inner surface of the bag and becomes difficult to take out increases.

  Further, the chopped strand filling body according to the present invention may be configured such that a fixed outer width portion having a fixed outer width dimension is provided between the first outer width reduced portion and the second outer width reduced portion. Good.

  In this way, by providing a portion having a constant outer width dimension (a constant outer width portion) between the first and second outer width reduction portions, the filling body as a whole has a more polygonal shape (for example, an octagonal shape rather than a hexagonal shape). (A shape close to). Therefore, it is possible to further stabilize the posture at the time of placing (particularly at the time of flat stacking) and to increase the number of stacked sheets.

  Alternatively, the chopped strand filling body according to the present invention may be one in which the first outer width reduced portion and the second outer width reduced portion are directly connected.

  In this way, by forming the outer width reducing portions directly connected to each other, for example, by adjusting the filling amount of the chopped strands or the closing position of the opening, the filling body is reduced by the amount having no constant outer width portion. Can be set relatively freely. Therefore, when loading a large number of fillers particularly in a packing member such as a metal container, the volume of which is determined to be a certain size, the fillers are arranged so that the opening does not face downward and a gap is formed as little as possible. Can be loaded in a stable posture while appropriately deforming. Therefore, as a result, it is possible to increase the number of filling bodies that can be loaded in the container.

  In the chopped strand packing according to the above description, a plurality of the packings are mounted in a predetermined arrangement with the bottom, the first outer width reducing portion, and the second outer width reducing portion oriented in the horizontal direction. It is also possible to provide a packing body of chopped strand packing bodies in which a plurality of packing bodies placed and arranged in a predetermined arrangement are stacked in layers.

  According to the chopped strand filling body of the present invention, the chopped strand filling body has a symmetrical shape on the side of the opening and the side of the bottom as compared with the conventional case. Therefore, when the packing bodies are stacked in a so-called flat stacking state as described above, the center of gravity of the packing bodies is stabilized near the center thereof, so that the number of stackable bodies can be increased, and the packing included in one packing body can be increased. It is possible to improve the number of bodies and thus the total amount of chopped strands.

  In the case where the packing body is formed by stacking a plurality of packing bodies as described above, the packing body according to the present invention includes a plurality of packing bodies arranged in a predetermined arrangement and a plurality of packing bodies vertically adjacent to each other. A non-slip sheet may be interposed between the body and the body.

  In this way, by interposing the non-slip sheet between the vertically adjacent fillers, it is possible to prevent the fillers from being displaced and dropping or to cause the stacked fillers to collapse during the loading operation. Can be avoided. Further, in the case of the packing according to the present invention, since the posture or shape at the time of stacking is stable, there is a space between all the packings constituting the same step (layer) and all the packings adjacent thereto. An anti-slip sheet can be interposed without leakage. Therefore, all of the stacked fillers can enjoy the non-slip action of the sheet without omission.

  Alternatively, when a plurality of fillers are stacked to form a laminate as described above, the laminate of the chopped strand filler according to the present invention has a non-slip film formed by printing on at least one surface of the bag. May be used.

  As described above, if the non-slip film is formed on the surface of the bag in advance by printing, the time required for the work can be reduced by eliminating the trouble of interposing the non-slip sheet.

  In the chopped strand packing according to the above description, the plurality of packings are placed in a predetermined arrangement, with the bottom facing downward and the opening facing upward, and placed in a predetermined arrangement. It is also possible to provide a stacked body of chopped strand packing bodies obtained by stacking a plurality of packing bodies in layers.

  With the bag of the shape according to the present invention, the chopped strand 2 is not filled up to the corner 103 of the flat bag 101 unlike the conventional case (see FIG. 13 and FIG. 14), so that the filler is placed at the bottom. Even close parts have a shape close to an ellipse. In particular, when the inner width reduction portion is formed of a seal portion, the first outer width reduction portion expands in an elliptical shape when the seal portion stands (by increasing the inclination angle of the seal portion). Therefore, when comparing the outer width dimension (maximum outer width dimension) of the filler, the outer width dimension of the bag provided with the inner width reduction portion is smaller when the chopped strand is filled. This is because the outer width of the original bag (flat bag 101) is maintained even in the state of the filler 105 in the case of the filler 105 provided with the bag (flat bag 101) having the conventional shape. In this way, by keeping the outer width small, it is possible to load as many fillers as possible into a limited-capacity packing member such as a container without limiting the placement posture. Therefore, it is possible to improve the loading efficiency and the transport efficiency.

  Further, the above object can be achieved by a method for producing a chopped strand filling according to the present invention. That is, the method for producing a filled body includes a chopped strand of glass, a bag having a bottom at one end, and a bag having an opening at the other end, and producing a chopped strand filled body in which the bag is filled with the chopped strand. In the method, at the bottom of the bag, an inner width reduction portion is provided in which the inner width of the bag decreases as approaching the bottom, filling the bag with chopped strands, squeezing the side of the opening, and closing the opening. In the bottom side, while forming the first outer width reduction portion in which the outer width dimension of the chopped strand packing decreases as approaching the bottom portion, and on the opening side than the first outer width reduction portion, the opening portion It is characterized by forming a second outer width reduction portion in which the outer width dimension decreases as approaching.

  As described above, in the method for manufacturing a chopped strand filling body according to the present invention, a bag provided with an inner width reduction portion on the bottom side is filled with the glass chopped strand, and the first outer side is placed on the bottom side of the filling body. The width-reduced portion is provided, and the second outer width-reduced portion is provided on the side of the opening than the first outer width-reduced portion, so that the chopped strand filler is conventionally used as the filler according to the present invention. In comparison, the opening side and the bottom side have a symmetrical shape. Thus, for example, when the filling body is placed in a flat posture, the position of the center of gravity of the filling body is stabilized at the central portion, and the shape is not easily collapsed at the time of placing. In addition, even when the filling body is placed in a posture in which the bottom portion faces downward and the opening faces upward, the position of the center of gravity of the filling body is stable, and the shape is not easily collapsed during placement. Therefore, a box-shaped packing member such as a container can be simplified or omitted, and thereby the cost required for packing can be significantly reduced.

  In addition, the method for manufacturing a filler according to the above description includes, for example, a plurality of fillers manufactured by this method, with the bottom, the first outer width reducing portion, and the second outer width reducing portion being oriented in a horizontal direction. After being packed in a predetermined arrangement and stacking a plurality of the packings placed in the predetermined arrangement in layers, packing the plurality of packings with a film-like packing member, the packing body of the packings. It can also be provided as a method of manufacturing a package of a chopped strand filling body to be formed.

  Alternatively, the method for manufacturing a filling body according to the above description is, for example, a method in which a plurality of filling bodies manufactured by this method are placed in a box-shaped packing member in a posture in which the bottom is downward and the opening is upward. It is also possible to provide a method for manufacturing a packed body of chopped strand packing bodies by forming a packing body of packing bodies by stacking a plurality of packing bodies placed in an array and mounted in a predetermined array in a layered manner. It is.

  As described above, according to the present invention, it is possible to pack a chopped strand filling at lower cost than before.

  Hereinafter, an embodiment of a chopped strand packing according to the present invention will be described with reference to FIGS. 1 and 2.

  FIG. 1 is a plan view of a chopped strand packing 1 according to an embodiment of the present invention. The filler 1 includes a chopped strand 2 made of glass and a bag 5 having a bottom 3 at one end and an opening 4 at the other end. The bag 5 is filled with the chopped strand 2.

  Here, the chopped strand 2 is obtained by cutting a glass strand formed by bundling a large number of glass filaments into a predetermined length (for example, 2 mm or more and 100 mm or less, preferably 3 mm or more and 40 mm or less).

  As a raw material of a glass filament (that is, a raw material of a molten glass), a glass known as a glass filament can be used. For example, E can be easily formed into a filament and has excellent properties as a glass filament. Glass (for example, having an alkali component content of 2.0 wt% or less) can be suitably used. Of course, other types of glass can be used, for example, AR glass having alkali resistance, C glass having acid resistance, D glass having low dielectric constant, H glass having high dielectric constant, high strength and high strength. It is also possible to use T glass having an elastic modulus, M glass having a high elastic modulus and containing beryllium, and NE glass having a low dielectric constant and a low dielectric loss tangent.

  In the present embodiment, the chopped strand 2 is a so-called water-containing chopped strand containing water, and the water content of the chopped strand 2 at the time of filling the bag 5 is 1% by mass or more and 13% by mass. It is set to the following, preferably set to 3% by mass or more and 10% by mass or less. If the water content is less than 1% by mass, the time required for white water to sufficiently penetrate into the chopped strands during papermaking becomes longer, and the time required for opening to monofilaments becomes longer, thereby lowering production efficiency. This is because the possibility of invite increases. On the other hand, if the water content exceeds 13% by mass, not only the improvement of the opening property during papermaking is not expected, but also the possibility that the chopped strands adhere to the inner surface of the bag 5 and become difficult to take out increases. The water content of the chopped strand 2 is calculated from (water content) = {(wet mass) − (dry mass)} / (wet mass) × 100. Here, the wet mass means the mass of the chopped strand 2 immediately after being taken out of the bag 5, and the dry mass means the mass after the chopped strand 2 is left at 120 ° C. for 120 minutes. .

  As shown in FIG. 2, the bag 5 has a bottom 3 at one end and an opening 4 at the other end, and is formed of a known resin film such as polypropylene or polyethylene. Further, on the bottom 3 side of the bag 5, there are provided inner width reduction portions 6, 6 in which the inner width Li of the bag 5 decreases as approaching the bottom 3 from the opening 4 side. In the present embodiment, the inner width reducing part 6 has a shape in which the inner width dimension Li is linearly reduced when the bag 5 is developed in a plane, and the inner end 6a has the bottom 3 and the outer end. 6b is connected to the constant inner width portion 7 of the bag 5 respectively. At this time, the inner width Lm (FIG. 1) of the constant inner width portion 7 and the inner width Lm of the opening 4 are the same.

  In the present embodiment, the bag 5 is finished in a bag shape by cutting a cylindrical resin film into a predetermined shape and sealing necessary portions by welding or the like. At this time, the seal portion 8 is formed at a position forming the outline of the bottom portion 3 and the inner width reduction portion 6.

  Then, the bag 5 is filled with a predetermined amount of the chopped strand 2 and the opening 4 is closed (closed) by appropriate means while the side of the opening 4 is squeezed, whereby the chopped strand shown in FIG. A packing 1 is obtained. In the chopped strand filling body 1, first outer width reduction portions 9, 9 whose outer width dimension Lo1 is reduced from the side of the opening 4 to the side of the bottom 3 are formed on the bottom 3 side, and On the opening 4 side rather than the outer width reducing portion 9, second outer width reducing portions 10, 10 are formed in which the outer width dimension Lo <b> 2 decreases from the bottom 3 side toward the opening 4 side. In the present embodiment, the second outer width reducing portion 10 includes a tapered surface portion 11 whose outer width dimension Lo2 is temporarily reduced and has a tapered partial conical surface shape, and a side closer to the opening 4 than the tapered surface portion 11. And a curved surface portion 13 having a shape in which the reduction ratio of the outer width dimension increases toward the closing portion 12.

  At this time, the shape of the second outer width reducing portion 10 is not only adjusted for the shape and size of the bag 5 but also for the size (length dimension), water content, and filling of the chopped strand 2 filled in the bag 5. It can be appropriately adjusted depending on the amount, the position of the closing portion 12, and the like. That is, even if the shape and size of the bag 5 are the same, the second outer width reduction portion 10 can take a different shape due to the difference in the size, the water content, or the filling amount of the chopped strand 2. As an example, in the present embodiment, for example, the bag 5 having an inner width dimension Lm of 600 mm, a depth dimension (the shortest distance from the bottom 3 to the opening 4) of 800 mm, and a width dimension of the bottom 3 of 420 mm is added to the length dimension. Is 13 mm, and 22 kg of chopped strand 2 of glass having a target moisture content of 6.5% by mass is filled.

  As means for closing the opening 4 of the bag 5, means for tying the opening 4 side of the bag 5 itself to close it, or squeezing with a binding member such as a string, wire, vinylite (registered trademark), or tape. Any means such as a means for binding the portion or a sealing means such as heat welding or thermocompression bonding can be employed. Note that vinylite refers to a vinyl binding tape having a wire as a core.

  As described above, in the present invention, the bag 5 provided with the inner width reducing portion 6 on the side of the bottom portion 3 is filled with the chopped strand filling body 1 formed by filling the chopped strand 2 of glass with the opening 4 of the filling body 1. The first and second outer width reduction portions 9 and 10 are provided on both sides of the bottom portion 3 and the bottom portion 3. By adopting such a shape, the chopped strand filling 1 has a symmetrical shape on the side of the opening 4 and the side of the bottom 3 as compared with the conventional shape (for example, the shape shown in FIG. 14). Thus, for example, when the filling body 1 is placed in a flat posture (so-called flat stacking), the center of gravity of the filling body 1 is stabilized at the center portion thereof, and the shape is not easily collapsed at the time of placing or loading. . Further, even when the packing body 1 is placed with the bottom 3 facing downward and the opening 4 facing upward (so-called vertical stacking), the position of the center of gravity of the filling body 1 is stable, and The shape does not easily collapse during loading. Therefore, a box-shaped packing member such as a container can be simplified or omitted, and thereby the cost required for packing can be significantly reduced.

  The chopped strand filling 1 according to the above description can be loaded and packed in various modes. Hereinafter, two representative examples of the packing mode of the filling body 1 will be described with reference to FIGS. 3 to 10 show only the main body of the filling body 1 (portion where the chopped strand 2 is filled) for easier understanding of the packing mode, and the opening 4 is more closed than the closed part 12. The illustration of the side is omitted.

  FIG. 3 is a perspective view of a pallet 15 and a support member 16 constituting the packing member 14 of the chopped strand filling 1 according to the first embodiment of the present invention. The support member 16 has a rectangular shape in a plan view (see FIG. 4). In the present embodiment, the support member 16 has a flat plate-like base portion 17 and a side portion 18 erected from the periphery of the base portion 17. And are integrally provided. The side surface portion 18 can mainly perform a positioning function in the plane direction of the first-stage (lowest-stage) filler 1 placed on the base portion 17.

  After preparing the packing member 14 having the above configuration, the plurality of packing bodies 1 are placed as the first-stage packing bodies 1 on the support members 16 constituting the packing member 14. In the present embodiment, the filler 1 is placed on the support member 16 with the bottom portion 3, the first outer width reducing portion 9, and the second outer width reducing portion 10 facing in the horizontal direction (so-called flat stacking). Do). Further, in the present embodiment, in a state viewed in a plan view, a plurality of packing bodies 1 arranged in a row in one of the vertical and horizontal directions (vertical direction in FIG. 4) are placed, and the plurality of packing bodies 1 are arranged. Are placed side by side in the direction (horizontal direction in FIG. 4) orthogonal to one of the vertical and horizontal directions. This completes the first-stage loading operation. At this time (at the time of loading of the first-stage fillers 1), the fillers 1 are placed so as to be in contact with the side surface portions 18 of the support members 16 so that each of the fillers 1 is positioned. Is placed. As described later, when the packing bodies 1 are stacked over a plurality of stages, the position of the first-stage (bottom-stage) packing body 1 affects the stable loading, and therefore, the packing bodies 1 are provided on the support member 16 as in the present embodiment. It is important to use the side surface portion 18 to position the first-stage filler 1.

  After the first-stage packing 1 is placed on the support member 16 in this way, the second-stage packing 1 is loaded. The loading of the second stage is performed in a state in which the direction of the rows of the filling bodies 1 is different from that of the first stage by 90 degrees. That is, as shown in FIG. 5, in a state where the packing member 14 (the support member 16) is viewed in a plan view, the packing member 14 is arranged in a direction (horizontal direction in FIG. 5) orthogonal to the first row of the packing bodies 1 (horizontal direction in FIG. 5). A plurality of packing bodies 1 are stacked so that the packing bodies 1 form a row, and the packing bodies 1 are stacked in the remaining space so that a plurality of rows of the packing bodies 1 are arranged. These second-stage packings 1 are all placed on the first-stage packing 1. Thus, the second-stage loading operation is completed.

  The above-mentioned operation is repeated, and after stacking a predetermined number of packing bodies 1, a film (not shown) is wound as necessary to integrate these stacked packing bodies 1 together. Alternatively, all of the stacked packing bodies 1 are covered with a cover member (not shown) capable of covering all of the stacked packing bodies 1. Thereby, the package 19 of the chopped strand filling 1 having the form shown in FIG. 6 is completed.

  In this case, although not shown, a non-slip sheet may be interposed between the vertically adjacent fillers 1 and 1. That is, after the first-stage loading operation is completed, a non-slip sheet is placed, and the second-stage filler 1 is placed on the non-slip sheet. Similarly, after the loading operation of the n-th stage is completed, the operation of placing the non-slip sheet and placing the (n + 1) -th filler 1 on the non-slip sheet is repeated. Thereby, all the fillers 1 and the non-slip sheet come into contact with each other. Alternatively, the use of the filler 1 having a non-slip film formed on at least one surface of the bag 5 may prevent slippage when the filler 1 is loaded. Also in this case, although not shown, the state in which all the fillers 1 can enjoy the non-slip effect of the non-slip membrane by loading the fillers 1 with the non-slip membrane always facing downward. Become.

  As shown in FIG. 1, the chopped strand packing 1 according to the present invention has a symmetrical shape on the side of the opening 4 and the side of the bottom 3 as compared with the conventional one (or a circular shape in a plan view). It becomes a shape close to). Therefore, when the packing bodies 1 are stacked in a so-called flat stacking state as described above, the number of stackable bodies can be increased by stabilizing the center of gravity of the packing body 1 near its center (in the example shown in FIG. 6). (8 steps × 6 = 48), the number of the packings 1 contained in one package 19 and the total amount of the chopped strands 2 in the package 19 can be improved.

  FIG. 7 is a perspective view of the packing member 20 of the chopped strand filling 1 according to the second embodiment of the present invention. The packing member 20 has a box shape, and is composed of, for example, a lattice container 21 made of metal.

  The packing operation of the packing body 1 using the packing member 20 having the above configuration is performed, for example, as follows. First, after preparing the packing member 20 shown in FIG. 7, the plurality of packing bodies 1 are placed in the packing member 20 as the first-stage packing body 1. In the present embodiment, the filler 1 is placed in the lattice-shaped container 21 constituting the packing member 20 (so-called vertical stacking) with the bottom 3 facing downward and the opening 4 facing upward. Further, in the present embodiment, as shown in FIG. 8, in a state where the grid-like container 21 is viewed in a plan view, a plurality of the filling bodies 1 forming a row in one of the vertical and horizontal directions (horizontal direction in FIG. 8). At the same time, the rows of the plurality of fillers 1 are placed side by side in a direction (vertical direction in FIG. 8) orthogonal to one of the vertical and horizontal directions. Further, as shown in the drawing, when a predetermined space is formed between the rows of the packing members 1, the packing members 1 are placed vertically so as to fill the space. This completes the first-stage loading operation.

  After the first-stage packing 1 is placed in the grid-like container 21 in this way, the second-stage packing 1 is loaded. At the time of loading in the second stage, the filler 1 is placed (loaded) in the same arrangement and posture as in the first stage. In this way, if the empty space exists above the lattice-shaped container 21 in a state where the filled bodies 1 are stacked up to a predetermined number of stages (for example, three stages), for example, the filled bodies 1 are stacked in a flat manner so as to fill the empty space. (FIG. 9). By stacking the packing 1 in the lattice-shaped container 21 in this manner, the package 22 of the chopped strand packing 1 is completed. In this case, as shown in FIG. 10, only the uppermost row of the packing bodies 1 is stacked in a flat stacking posture, and the remaining stages of the packing bodies 1 are all stacked in a vertical stacking posture.

  In the case of the bag 5 (FIG. 2) having the shape according to the present invention, the chopped strand 2 is not filled up to the corner 103 unlike the conventional case. It has a close shape (FIG. 8 etc.). In particular, when the inner width reducing portion 6 is configured by the seal portion 8, the seal portion 8 stands up (in FIG. 1, by changing from a position drawn by a two-dot chain line to a position drawn by a solid line), The outer width reduction portion 9 expands in an elliptical shape. Therefore, when comparing the outer width dimension (maximum outer width dimension) Lf of the filling body 1, the outer width dimension Lf of the bag 5 provided with the inner width reducing portion 6 is smaller when the chopped strand 2 is filled. . This is because, in the case of the filling body 105 including the bag (the flat bag 101) having the conventional shape, the outer width dimension of the flat bag 101 before the filling is maintained even in the state of the filling body 105 (FIGS. 13 and 14). Therefore, the shape becomes more symmetric, and it is easy to take a stable mounting posture. Therefore, when the space cannot be accommodated vertically in the upper part of the lattice-shaped container 21 but is large enough to be accommodated in the flat case, the space is utilized to make use of this space, and the uppermost stage has a posture different from other stages. A plurality of packing bodies 1 can be stacked (3 rows × 3 = 9). In addition, as shown in FIG. 8, for example, as shown in FIG. 8, in a state where the packing bodies 1 are stacked so as to form a plurality of rows, a new packing body 1 is mounted between each row because the outer width dimension Lf is smaller than the conventional case. There is space to put it. Therefore, it is possible to increase the number of stacked bodies 1 in the vertical stacking posture by that amount (2 rows × 5 pieces + 1 row × 2 pieces = 12 pieces). Can be accommodated. Therefore, it is possible to increase the number of the packing bodies 1 per one packing body 22 and to reduce the number of the packing bodies 22 to be conveyed and consequently the conveyance cost.

  The embodiment of the chopped strand packing 1 according to the present invention and one embodiment of the manufacturing method thereof, and the two embodiments of the package provided with the packing 1 have been described above, but these are naturally within the scope of the present invention. It can take any form.

  For example, in the above embodiment, the case where the first outer width reducing portion 9 and the second outer width reducing portion 10 are adjacent to each other is illustrated as the shape of the filling body 1 as shown in FIG. Such a filling body 1 can also take other forms.

  FIG. 11 is a plan view of a chopped strand filling body 23 according to another embodiment of the present invention. This filler 23 has a constant outer width portion 24 in which the outer width dimension (maximum outer width dimension) Lf is constant between the first outer width reducing section 9 and the second outer width reducing section 10. This is different from the packing 1 shown in FIG.

  FIG. 12 is a plan view of a chopped strand filling body 25 according to another embodiment of the present invention. This filling body 25 is shown in FIG. 1 and the like in that the bottom 3 of the bag 5 is not constituted by the linear sealing portion 8 and only the first outer width reducing portions 9 on both sides thereof are constituted by the sealing portion 8. It is different from the filling 1 and the filling 23 shown in FIG. By adopting such a shape, the planar shape of the filling body 1 can be made closer to a polygonal shape (or a perfect circular shape), so that, for example, an effect of stabilizing the posture when stacked can be expected.

  In the above description, the case where the inner width reducing portion 6 of the bag 5 is constituted by the seal portion 8 is exemplified, but it is needless to say that other forms can be adopted. For example, it is possible to form the inner width reducing portion 6 by the folded portion of the film constituting the bag 5, or to form the inner width reducing portion 6 by fixing the overlapping portions of the films to each other by means other than a seal. It is also possible. Further, it is also possible to adopt a shape in which gussets (so-called gussets) are provided at both ends in the width direction of the bag 5 or at the bottom 3.
