[Embodiment of the invention]

 1 to 6 show an embodiment of this invention. It should be noted that, in these figures, for the sake of simplicity, the state in which the strap is not provided is shown.

Reference numeral 10 is a bag, which is composed of a bag body 12 and a single inlet / outlet port 14.

The bag body 12 has two sheets 15 and 16 made of a plastic film or the like, which are welded on four sides thereof, on its four circumferences. That is, they are a linear upper weld 18, a left weld 20, a right weld 22, and bottom welds 24, 26, all of which are linear. The bag body 12 is a portion below the upper welding portion 18. The front and back sheets 15, 16 are welded to each other in the upper welded portion 18, but even on the extension line of the upper welded portion 18, the front and back sheets 15 are slightly left of the center portion in FIG. Nos. 15 and 16 are not welded.

The filling / discharging port 14 is a flat cylindrical body also made of a plastic film, and carries out both filling and discharging of contents. The lower end 30 is located slightly below the point 28 according to the upper welded portion 18. The front and back sheets 32 and 34 forming the tubular flat body are welded to each other on both side portions 35 and 35. The tubular flat body is attached to the bag body 12 as follows. That is, at the point 28, the sheet 32 on the front side of the filling / discharging port in FIG. 1 is welded to the sheet 15 on the front side of the bag body 12, and the sheet 34 on the back side constituting the filling / discharging port is It is welded to the back-side sheet 16 that constitutes the bag body 12. In this way, the filling / discharging port 14 is welded and fixed to the bag body 12, and the bag body 12 communicates with the outside only at the portion 28 corresponding to the lower end of the filling / discharging port 14. All the other parts are closed.

The front and back sheets 15, 16 extend above the upper welded portion 18 to form an extension portion 19. The front and back sheets 15 and 16 are welded to the upper end 34 and the left and right side portions 36 and 38 of this extension. However, in the welded portion 34 at the upper end, the front and back sheets 15 and 16 are not welded at the left side portion 40 in the drawing. The location 40 is located at a position that is axially coincident with the location 28 of the upper welded portion 18. Then, the flat tube-shaped injecting / exhausting port 14 passes through this portion 40. In this embodiment, the front and back seals 15, 15 and the inlet / outlet port 14 are not welded at the location 40. Numeral 39 is a handholding hole provided in the extension, through which a finger can be inserted to carry the bag by hand.

A space portion between the sheet 15 on the front side and the filling / discharging port 14 is a pocket portion 42 for accommodating a folding state, which will be described later. A lid 44 for closing the pocket 42 is welded to the portion 40 of the rear-side sheet 16 at the location 40.

In the state shown in FIG. 1, after injecting liquid or the like into the bag body 12, the injection / exhaust port 14 is folded in the axial direction and stored in the pocket portion 42. Then, the lid 44 is covered over the pocket portion 42, and the free end 46 thereof is sandwiched and held between the folded body 47 of the filling / discharging port 14 and the front sheet 15 constituting the bag body 12 (FIG. 6). . Since it did in this way, the folding state of the folding body 47 is hold | maintained. Therefore, even if the liquid or the like contained in the bag tries to leak to the outside, it cannot pass through the injection / discharge port 14 in which the bent state is maintained. Note that, in FIG. 6, the front and back sheets 32 and 34 forming the inlet / outlet port 14 are each represented by a single line for simplicity, and the wall thickness is not represented. Further, although the folded body 47 shows the corner portion in an arc shape, in reality, it is bent in a fold line shape, and the corner portion of the bent portion can prevent passage of water and the like.

The bottom portion 50 of the bag body 12 will be described with reference to FIG. The bottom portion 50 is folded in a gusset shape. That is, the front and back sheets 15 and 16 are folded back to the facing surface side of the bottom portion 50. The folding pieces 15a and 16a are continuous at the top portion 51. In this way, the two front and back folded portions 52 and 54 are formed. Welded portions 56 and 58 are formed in diagonal directions in each of the folded portions 52 and 54 so that the liquid in the container does not reach the corner portion 53 of the bottom from the welded portions 56 and 58. It is configured. With such a bottom structure, when water or the like is stored inside, the bottom 50 expands, as shown in the perspective view of FIG.

FIG. 7 shows a modified example, in which case the lid 46 for the pocket is configured to be located on the front side of the front sheet 15, and the lid 46 and the front sheet 15 are combined. Both the male and female members 60 of the surface fastener are present between them, and the engagement of the both holds the state in which the pocket portion 42 is closed by the lid 44.

1 to 7, the straps are omitted for simplification, but FIG. 8 is provided with such straps 100, and it is possible to carry the backpack in the form of a rucksack. That is, the carrying cord 100 is composed of two cords 102 and 104, and the upper ends 106 and 108 of the two cords are tied to the hole 39 provided at the center of the upper end of the bag. Actually, the two strings 102 and 104 are one continuous string bent at the center, and this bent portion is tied to the hole 39. The lower ends 110, 112 of the cords 102, 104, respectively, are tied to two holes 114, 114 (shown on the right side only) at opposite ends of the bottom of the bag. You can prepare a long string and shift the position of the knot in the string according to the size of the body of the person who carries it. That is, for a person with a large body, tie the string to the bag body as close to the lower end as possible. On the other hand, in the case of a person with a small body, the lower end of the string is tied to the holes 114 and 114 with as much space as possible.

9 to 19 show another embodiment of the present invention. In FIG. 9, for the sake of simplicity, the upper end of the strap is shown before being attached to the bottom of the bag. The straps are not shown in the figure and are actually quite long.

Reference numeral 10 denotes the entire bag, which is composed of a bag body 12 and an injection / discharge port 14 extending above the bag body 12. The bag 10 is formed of two sheets, the front and back. The front and back sheets 16, 18 are folded at both right and left sides to form gussets 20, 22. The front and back sheets 16 and 18 are welded 24 and 26 in a V-shape including the gussets 20 and 22 on the left and right sides in the width direction, which are substantially central portions in the longitudinal direction of the bag 10. At the upper ends of the welded portions 24 and 26, the gussets 20 and 22 do not exist, and only the front and back sheets 16 and 18 are welded. The welding plugs 28 and 30 extend upward from this portion to form the elongated injection / discharge port 14. The upper end of the inlet / outlet port 14 is open. At the upper end of the bag 10, the front and back sheets 16 and 18 including the gusset portions 20 and 22 are welded 32 and 34. On the left side of the figure, a left strap 36 is formed between the two welded portions 24 and 32, and on the right side of the figure, a right strap 38 is formed between the two welded portions 26 and 34. There is. The strap 40 is formed by welding the portions 40 and 42 shown in FIG. 10 at the welded portion 32, and the strap 38 has the two portions 44 and 46 shown in FIG. It is welded by 4 to form a ring shape.

Reference numerals 48 and 50 denote stop members provided on the left and right sides of the injection / discharge port 14. This stop member is formed by welding the front and back sheets 16, 18 at the welded portions 52, 54; 56, 58 on the left and right sides, respectively, and at the upper end portions 60, 62. The stop members 48 and 50 have three holes arranged in series in the longitudinal direction thereof. The hole 64 is composed of round holes at both upper and lower ends and a notch for connecting the holes. Although not shown, the holes 64 may be arranged in the width direction of the fastening member.

Next, a procedure for closing the filling / discharging port 14 of the bag 10 of this embodiment will be described.

First, as shown in FIG. 12, contents such as water are injected into the bag body 12. Then, the inlet / outlet port 14 is grasped by a hand and extended upward.

Next, as shown in FIG. 13, the vicinity of the upper end 15 of the filling / discharging port 14 is wound several times in the axial direction of the filling / discharging port 14 to form a winding ball 66.

Next, as shown in FIG. 14, the bulky portion 67 is formed by folding the winding ball 66 in two along a fold line parallel to the axis of the filling and discharging port 14. It is preferable that the bulky portion 67 be further bulky by adopting a fourfold folding or more folding in place of the double folding.

Next, as shown in FIG. 15, the pouring / discharging port 14 is inserted into the three holes 64, 64, 64 of the stopper member 48 with one stopper member 48 folded in three. Then, the stopper member 48 is positioned on the base side of the injection / discharge port 14.

Next, as shown in FIG. 16, the other stopper member 50 is folded in half and the lump 67 at the tip of the inlet / outlet port 14 is inserted into the two holes 64, 64 on the tip side. To do. Since 67 is bulky, it is pressed into the hole 64 of the stopper member 50 and held in this state. Thereby, leakage of the liquid, which is the content of the bag 10, is completely prevented.

17 and 18 show a state in which the free ends of the left and right straps 36, 38 of the bag 10 are attached to the lower end of the bag. That is, the upper ends 32 and 34 of the straps 36 and 38 are welded to the left and right ends of the lower end of the bag to form a backpack-like strap. However, instead of this, holes may be provided on both sides of the lower end of the bag, and the holes may be tied through the ends of the straps 36, 38. In this way, the length of the carrying strap can be adjusted according to the size of the backpacker's body.

The following is how to release the closed state of the filling / discharging port of the bag. That is, the stopper member 50 is disengaged from the bulky portion 67 at the tip of the filling / discharging port 14. Then, the winding ball 66 on the front end side of the filling / discharging port 14 is unfolded to sufficiently extend the filling / discharging port in its longitudinal direction. In this state, the bent state is widened while the other stopper member 48 is engaged with the inlet / outlet port 14. In this state, since the hole 64 of the stopper member 48 is not engaged with the bulky portion of the filling / discharging port, the discharge of the liquid from the filling / discharging port is not completely blocked, but a small amount is discharged, that is, so-called. It will be in a finely cut state. This is shown in FIG.

In this embodiment, the method of using the stopper members 48 and 50 to close the injection outlet is not limited to this. For example, as shown in FIG. 20, both the holes 64, 64 on the most base sides of the two stopper members 48, 50 may be inserted into the injection outlet 14. In this case, it is necessary to make the bulky portion 67 on the tip side of the inlet / outlet port 14 remarkably large so as not to release the lump state.

In this embodiment, the reason why the plurality of holes 64 are provided in the stopper members 48 and 50 is as follows. That is, when the inlet / outlet port 14 is folded in its longitudinal direction as shown in FIG. 13, it may be folded only once or may be folded many times. As a result, the length of the folded inlet / outlet port 14 varies. When the inlet / outlet port 14 is long, it is preferable to use the hole 64 on the tip side of the stopper members 48, 50 or the hole 64 in the middle. On the other hand, when the length of the folded inlet / outlet port 14 is relatively short, it is preferable to use the holes on the base side or the middle holes of the stopper members 48 and 50.

In addition, in each of the above-mentioned embodiments, each has a single flat tubular body, and this serves to both inject and discharge the contents. However, instead of this, a flat cylindrical body dedicated to the injection of the contents may be arranged, or only a flat cylindrical body for discharging the contents may be arranged. That is, in the former case, for example, after the content is injected from the flat tubular body, the tip thereof is heat-sealed, for example. In this case, the contents of the bag will be taken out by cutting the bag body. In the latter case, for example, a bag is formed with a liquid or the like stored therein, the tubular flat body is extended outside the bag, and the tip thereof is heat-sealed. In this case, when taking out the contents, the heat seal portion at the tip of the flat tubular body may be cut off.

Further, the bag body of the present invention is basically a flat one composed of two front and back sheets (before filling the contents). However, a gusset may be interposed between the two front and back sheets.
