[0005] In the present invention, the entire periphery of the bag is opened at only one place where the inlet / outlet is attached, and is closed at other places. Therefore, there is no leakage of the contents, such as liquid, in other places. In addition, the single inlet / outlet, which is the only point through which the contents pass, is folded in the axial direction, so that the flow of the liquid in the axial direction at the inlet / outlet, especially the liquid inside the bag body, is discharged to the outside. Leakage can be reliably prevented. Moreover, in the folded state in which the leakage of the liquid can be reliably prevented as described above, the liquid can be inserted into the pocket, so that the folded state can be reliably maintained, and thus, the leakage of the liquid as the contents to the outside can be more reliably achieved. Can be prevented.

In addition, since there is provided a lid for covering the pocket portion and means for stopping the lid while covering the pocket portion , the folded inlet / outlet pops out of the pocket portion and is folded. Can be reliably prevented from leaking out of the liquid as contents to the outside.

Furthermore, since the lid has means to hold in a state stopped down the injection outlet, by maintaining this way the injection outlet in a state stopped down, put the bag inside the liquid or the like in portions ( (So-called thinning). Further, by increasing the degree of the narrowing, the discharge of the liquid or the like in the bag can be temporarily stopped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the present invention by Figures 1-6
A specific example of a part of the configuration will be described. That is,
This invention narrows the inlet and outlet to the lid that covers the pocket.
One feature is the provision of means that can hold
1 to 6 show such a configuration.
Although not shown, a specific example of the configuration on which the present invention is based is shown, and will be described below.

Reference numeral 10 denotes a bag according to the present invention, which is formed by a bag body 12 and a single inlet / outlet 14.

The bag body 12 has two front and back sheets 15 and 16 made of a plastic film or the like welded on its four circumferences. That is, the upper welding portion 18, the left welding portion 20, the right welding portion 22, and the bottom welding portion 2 are all linear.
4,26. Note that the bag body 12 is provided with an upper welding portion 18.
The lower part shall be referred to. The front and back sheets 15 and 16 are welded in the upper welded portion 18, but even on an extension of the upper welded portion 18, the front and back sheets 15 and 16 are located at a position 28 slightly to the left of the center in FIG. 1. 15 and 16 are not welded.

The inlet / outlet port 14 is a flat cylindrical body also made of a plastic film, and performs both injecting and discharging of contents. The lower end 30 is connected to the upper welding portion 18.
Therefore, it is located slightly below the point 28.
The front and back sheets 32, 34 constituting this tubular flat body are mutually welded at both sides 35, 35. And
The tubular flat body is attached to the bag body 12 as follows. That is, at the point 28, the sheet 32 on the near side of the inlet / outlet in FIG. 1 is welded to the sheet 15 on the near side of the bag body 12, and the sheet 34 on the back side forming the inlet / outlet is 12 is welded to the sheet 16 on the rear side. In this way, the inlet / outlet port 14 is welded and fixed to the bag body 12, and only at the location 28 corresponding to the lower end of the inlet / outlet port 14,
The bag main body 12 is in communication with the outside, and the bag main body 12 is entirely closed at other locations.

The front and back sheets 1 are located above the upper welding portion 18.
5 and 16 extend to form an extension 19. The front and back sheets 15 and 16 are welded to the upper end 34 of the extension and the left and right sides 36 and 38. However, in the welded portion 34 at the upper end, the front and back sheets 15 and 16 are not welded at the location 40 on the left side in the figure. This part 4
0 is located at a position axially coincident with the location 28 in the upper welded portion 18 described above. Then, the injection / exhaust port 14 of the flat cylindrical body passes through this location 40. In this embodiment, the front and back seams, 15, 16 and the inlet / outlet port 14 are not welded at the location 40. Numeral 39 denotes a hand-held hole provided in the extension part, through which a finger is inserted to hold the bag by hand.

The space between the sheet 15 on the front side and the inlet / outlet 14 is a pocket 42 for accommodating a later-described inlet / outlet in a folded state. A cover 44 for closing the pocket portion 42 is welded to the portion 40 of the rear side sheet 16.

In the state shown in FIG.
After the injection, the injection / ejection port 14 is folded in the axial direction and stored in the pocket 42. Then, the lid 44 covers the pocket portion 42, and the free end 46 is sandwiched and held between the folded body 47 of the inlet / outlet 14 and the front side sheet 15 constituting the bag body 12 (FIG. 6). . By doing so, the folded state of the folded body 47 is maintained. Therefore, even if the liquid or the like stored in the bag tries to leak to the outside, it cannot pass through the inlet / outlet 14 maintained in the bent state. In FIG. 6, for simplicity, the front and back sheets 32 and 34 constituting the inlet / outlet 14 are each represented by one line, and the thickness is not represented. The corners of the folded body 47 are arc-shaped, but are actually bent in a folded line shape, and the corners of the bent portions can prevent passage of water and the like.

The bottom 50 of the bag body 12 will be described with reference to FIG. The bottom 50 is folded in a gusset shape. That is, the front and back sheets 15 and 16 are
, It is folded back to the opposite surface side. Folded piece 1
5a and 16a are continuous at the top 51. In this way, two folded portions 52 and 54 are formed. Each of the folded portions 52 and 54 is formed with oblique welding portions 56 and 58 so that the liquid in the container does not reach the bottom corner 53 from the welding portions 56 and 58. Have been. With such a bottom structure, when water or the like is stored inside, the bottom 50 is widened, as shown in the perspective view of FIG.

FIG. 7 is a premise of the present invention shown in FIGS.
A modification example of a specific example of the configuration shown in FIG .
The lid 46 for the pocket is configured to be located on the front side of the front sheet 15, and the male and female members 60 of the hook-and-loop fastener exist between the lid 46 and the front sheet 15. Then, the state where the pocket portion 42 is closed by the lid 44 is maintained.

In FIG . 7 , the upper welding portion 18 defining the upper edge of the bag body 12 is placed on an extension portion 19 having substantially the same width.
In appearance, the upper end 34 looks like the upper end of the bag body. Alternatively, it is shown in FIG. 8
O urchin, only the pocket portion 40 from the upper welding unit 18 demarcating the bag body 12 protrudes on both, may be accommodated by folding the injection outlet 14 here. The manner of attaching the injection port 14 to the bag body 12 is the same as in the case of FIG.

In the above-described example , the bag body is a flat body made of two sheets, front and back, and has a gusset at the bottom. Are also included in the scope of the present invention.

The stopping means in Claim 1, if in FIG. 1 is a挾着structure by a front side sheet 15 of the folded body 47 and the bag body of the injection outlet, in the case of FIG. 7, the surface fastener 60. Separate adhesive tape as a detent structure,
Arbitrary things such as clips can be adopted.

[0024] FIGS. 9-12 show the actual施例of the present invention.

This embodiment is similar in many respects to FIG. 1 and differs only in the structure of the lid 44.

The lid 44 extends upward a little longer than in the case of FIG. Then, both sides of the lid 44 are cut out 62, 62 into semicircular shapes facing each other. Thus, a narrow portion 63 extending in the horizontal direction is formed at the upper end of the lid 44. The left side portion 64 of the narrow width portion 63 is formed in a folded state as shown in the figure. A male member 65 of a hook-and-loop fastener is attached to the folded portion 64. A female member 67 of a hook-and-loop fastener is attached to the right side portion 66 of the narrow width portion 63. The distance from the upper end 34 of the extension portion 19 of the bag body 12 to the upper end of the lid 44 substantially corresponds to the distance between the upper end 34 and the upper welding portion 18 of the bag body 12. A female member 68 of a hook-and-loop fastener is attached on the left side in the figure, and a male member 69 is attached on the right side, on the upper surface of the portion 28 which is arranged on the same straight line in the horizontal direction as the upper welded portion.

In this way, when the lid 44 is folded back at its base and superimposed on the bag body 12, the lid 4
The male member 65 and the female member 67 of the hook-and-loop fastener located at the upper end of the upper surface 4 are overlapped with the female member 68 and the male member 69 of the hook-and-loop fastener located at the point 28, respectively. Reference numeral 42 is held in a state closed by a lid 44. That is, in this embodiment, each member 65, 67, 6 constituting the hook-and-loop fastener is used.
8, 69 constitute stop and stop means.

When the liquid or the like in the bag 12 is discharged to the outside, the contents are discharged by extending the entrained injection / discharge port and positioning its free end downward, for example. As shown in FIG. 12, the extended injection port is squeezed, and the narrow portion 63 of the lid 44 is wound therearound. At this time, the male member 65 and the female member 67 of the hook-and-loop fastener come into contact with each other by folding the right side portion 66 of the narrow width portion 63 toward the near side of the drawing and further folding it over the right side portion 64. By the engagement of the two, the narrow width portion 63 is held in a wound state. In this way, since the inlet / outlet port 14 is maintained in a state of being narrowed down, a large amount of liquid or the like inside the bag is not discharged to the outside through the inlet / outlet port, and only a small amount is discharged. This is a so-called squeezing state. Since the male member 65 and the female member 67 have a certain length in the width direction of the lid 44,
It is possible to relatively move the contact position of both,
Thus, the diameter of the ring formed by winding the narrow portion 63 can be adjusted. When the diameter is made extremely small, it is possible to temporarily stop the discharge of the liquid and the like inside the bag.

The male member and the female member of the hook-and-loop fastener in the above embodiment may be used interchangeably.

FIGS. 13 to 15 show another embodiment. FIG.
The difference from this embodiment is the manner in which each member of the hook-and-loop fastener is attached.

That is, the male and female members of the hook-and-loop fastener are provided on the left and right sides of the narrow portion 63 at the tip of the lid 44, as in the embodiment of FIG. That is, the narrow portion 6
A male member 65 is provided on the back side of the left side portion 64 of the third, and a female member 67 is provided on the front side of the right side portion 66. However, unlike the embodiment of FIG. 9, in this case, a relatively large female member 69 is provided in the constricted portion 68 of the lid 44. When the lid 44 is folded, the male member 70 of the hook-and-loop fastener is attached to a position corresponding to the female member 69, that is, an intermediate position between the upper welding portion 18 of the bag body 12 and the upper end 34 of the extension portion 19. Have been. Lid 4
As the stopping means when block 4 is closed, the above-mentioned female member 69 is used.
And the male member 70 work. On the other hand, the action of holding the elongated injection port 14 in a narrowed state is achieved by the male member 65 and the female member 67 described first.

As described above, this embodiment is different from the embodiment shown in FIG. 9 in that it has a means for stopping and stopping in a state where the lid is closed, and has a function of narrowing the extended inlet and outlet. The engagement means is separate.

Furthermore to indicate <br/> another embodiment in FIGS. 16 and 17. In this case, the female member 71 of the hook-and-loop fastener is provided at the tip of the lid 44, and the male member 72 is attached to a position corresponding to the female member 71 when the lid 44 is folded back toward the bag body 12. . The female member 71 has a hole 7
3 are formed. The hole 73 includes circular openings 74 and 75 on both left and right sides and a linear cut 76 connecting the two.

The injection port 14 is inserted into the hole 73 in a state where it is extended. As a result, the inlet / outlet port 14 is in the hole 7
It is narrowed down by 3. The hole 73 has circular openings 74 and 75 at both left and right ends, so that the opening can be easily expanded. Therefore, the insertion and discharge port 14 can be easily inserted.
Moreover, a linear cut 7 is formed between the two circular openings 74 and 75.
By having 6, the inserted inlet / outlet port 14 is strongly pressed at this point, and an effective narrowing state can be obtained.

Then, the injection / ejection port 14 is connected to the pocket 42.
When the lid 44 is closed in a state where the lid is folded inside, these male and female members 71 and 72 serve as means for stopping the closed state of the lid.

FIGS. 18 and 19 show still another embodiment.
In this case, the lid 44 is further extended than the female member 71, and forms a surplus portion 77. A hole 78 is provided in the surplus portion 77. This hole 78 is shown in FIG.
As in the case of the hole 73, there are two circular holes 79 and 80 on both left and right sides, and a linear cut 81 connecting these two holes.

In this case, the male and female members 71 and 72 of the hook-and-loop fastener function as means for stopping the closed state of the lid 44. However, the female member 71 is not provided with a hole,
A hole is provided in the upper surplus portion 77, and when the elongated injection port 14 is narrowed, the injection port is inserted into this hole. Thus, in this embodiment, the lid 4
The means for stopping the closed state of 4 and the means for narrowing the inlet and outlet are separate.

FIG. 20 shows still another embodiment of the present invention. In this case, the bag of the present invention is formed so as to be carried on a backpack. That is, holes are provided on both the left and right sides of the bottom of the bag.
A string is hung between two holes.

[0039]

According to the bag of the first aspect, with a simple structure, it is possible to reliably prevent the leakage of the contents such as liquids, and it is possible to extend the injection and discharge port and hold it in a squeezed state. As a result, it is possible to squeeze out the content such as liquid, and it is also possible to temporarily stop the discharge of the content by adjusting the degree of narrowing.

In the bag according to the second or third aspect , the inlet / outlet can be held in a narrowed state by a simple structure.
