Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid bag for holding a fluid such as a liquid such as a beverage or a liquid detergent, or a powder.

[0002]

Beverages such as juice and soft drinks,
Liquids such as liquid detergents and shampoos are used in a state of being filled in various containers and the like. In recent years, resource protection and environmental problems have been particularly emphasized. Therefore, especially for liquid detergents and the like, refilling liquid detergents using a liquid bag 10 as shown in FIG. 15 are widely commercially available so that the content liquid can be replenished without making the container disposable. ing. The liquid bag 10 of the liquid detergent for refilling in the illustrated example is
Composed of a sheet made of synthetic resin such as polyethylene,
The four peripheral portions 12 are integrated by heat sealing, and the liquid detergent is held in a holding portion 18 formed in the center thereof. When using, the upper part (from notch 14)
After cutting along the upper side 16 and opening the upper part of the holding part 18, the liquid bag 10 is turned upside down to allow the liquid detergent in the holding part 18 to flow out and be refilled and refilled in another container.

[0003]

However, with such a liquid bag, when the container is refilled with the content liquid, the outflow control of the content liquid does not become stable, and the content liquid spills out of the container. There was an occasion. In addition, once the liquid bag is opened, it cannot be sealed again.Therefore, it is necessary to discharge the content liquid, and discard the content liquid that could not fit in the transfer container or fall it over. It was necessary for each worker to carry out a preservation process in consideration of leakage of the residual liquid due to such reasons. Therefore, the content volume of the refill bag is set so that the content liquid can be transferred when refilling once.
In reality, it is marketed with a smaller amount than the content of the transferable container. However, it is disadvantageous that there is such a restriction that the internal content needs to be reduced.

The present invention has been made in order to solve the above-mentioned problems, and the contents can be easily and accurately discharged, and the contents can be reused by interrupting the leakage of the contents. Is provided.

[0005]

The fluid bag of the present invention comprises:
In a fluid bag made of a synthetic resin sheet in which a peripheral portion is integrated and a holding portion for holding a fluid inside is formed, an elongated lead-out path connected to the holding portion is formed. To do. At this time, it is preferable that the leading end of the lead-out path is narrower than that on the side of the connecting portion with the holding portion. Furthermore, the connection direction of the holding part and the derivation path,
It is desirable that the longitudinal direction of the lead-out path does not match. Further, it is preferable that a notch for opening the discharge portion at the tip of the outlet path is formed in the peripheral portion. Further, it is preferable that a notch line is formed at a position facing the notch with the lead-out path interposed therebetween, and a line extending from the notch intersects with the notch.
In the present invention, the term “fluid” means a fluid material having no fixed shape, and is not limited to gas or liquid, and includes solids as long as it is fine such as granules.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The fluid bag of the present invention is made of a synthetic resin having resistance to contents, that is, waterproof and water resistant if the contents are aqueous solutions, and has a fluid inside. It is a bag whose peripheral parts are integrated so as to form a space that can be formed. An example of the present invention will be described with reference to FIG. In the fluid bag 20 of this example, two synthetic resin sheets are integrated by heat-sealing their peripheral portions 22 to 25, and an inner portion 26 surrounded by the peripheral portions is formed.
The holding portion 28 surrounded by the two sheets is formed on. Further, in the present invention, an elongated lead-out path 30 through which the contents can pass is formed inside thereof. In the illustrated example, the lead-out path 30 has a connecting portion 32 at one end thereof connected to the holding portion 28 by a connecting portion 36, and a discharge portion 34 at the other end is sealed by the peripheral portion 23. That is, the holding portion 28 and the lead-out path 30 are connected to each other by the connecting portion 36.
Are separated by the separating portion 38 and are formed into respective shapes. Therefore, in this fluid bag 20, a closed system is formed by the holding portion 28 and the outlet passage 30, and the contents are sealed and held therein.

In order to manufacture such a fluid bag, for example, three peripheral portions of two synthetic resin sheets are integrally formed into a bag shape by a sticking means such as heat sealing. After filling the contents from the non-integrated part, the part opened for the filling is integrated to seal the contents in the bag, and the holding part 28 and the outlet path 30 are connected to each other by the connecting part 36. As in the case of the peripheral portion, the separation portion 38 may be formed by an integrated means such as heat sealing so that the separation portion 38 is separated. Alternatively, for example, one synthetic resin sheet is bent, and the bent portion is used as the peripheral portion 25, and both sides are integrally formed by heat sealing or the like to form the peripheral portions 23 and 24 into a bag shape. Alternatively, the holding portion 28 and the outlet passage 30 may be formed by filling the contents and forming the separating portion 38.

To use the fluid bag 20 described above,
The vicinity of the discharge portion 34 of the outlet passage 30 may be cut off from the peripheral portion 22 by using hand or scissors, and the discharge portion 34 may be opened as shown in FIG. 2. After that, as shown in FIG. When is pressed, the contents in the holding portion 28 flow out from the tip of the holding portion 28 via the outlet passage 30. Since the fluid bag of the present invention is made of a soft packaging material, it can be easily pressed, and after use, it can be rolled into small pieces and stored or discarded. Further, the synthetic resin sheet may be composed of a plurality of sheets or a multi-layered body of a plurality of species, depending on the use or contents. Further, since it can be manufactured from only one kind of resin material, it can be easily disposed of and recycled. Also,
Since it is an elastic bag, it is also possible to stack and store a plurality of fluid bags. Further, since the fluid bag of the present invention is made of a synthetic resin and has flexibility, it does not simply press the holding portion 28, but, as shown in FIG. The contents in the holding portion 28 can be made to flow out even by winding from the location, and the contents can be almost completely flowed out, and even if the contents have viscosity or powder. it can.

With such a fluid bag 20, since the contents flow out from a fixed portion, that is, from the discharge part 34 of the elongated lead-out path 30, and further, the contents flow out in a linear fashion without spreading. It becomes easy to control the outflow. Further, since the contents can be blown out toward the target and flow out, it is possible to use the discharge part 34 of the outlet path without contacting the target. Thus, for example, when the content is a beverage,
Even when shared by a plurality of people, each person's mouth is the discharge part 3 of the outlet path.
It can be served without touching 4.

Further, it is preferable that the leading end side of the outlet passage having the discharge portion 34 is narrower than the connecting portion side with the holding portion 28. That is, in FIG. 1, the width d is preferably smaller than the width D. By narrowing the tip side in this way, the outflow pressure from the discharge part 34 at the tip can be further increased, and the contents are collectively discharged in a linear shape without spreading, and the outflow control becomes easier to perform. . Therefore, the contents can be easily transferred to a container having a small diameter. Further, the connecting direction of the holding portion 28 and the lead-out path 30 (arrow A in FIG. 1) and the longitudinal direction of the lead-out path 30 (FIG. 1).
In the middle, it is preferable that the arrow B) does not match. By doing so, the flow direction when the content in the holding section 28 flows out of the discharge section 34 of the outlet passage 30 is changed on the way, and the outflow control of the content is facilitated. It is possible to increase the length of the lead-out path 30 without making the entire fluid bag large, and it is possible to achieve compactness. In addition, the connecting direction A between the holding portion 28 and the lead-out path 30
And the longitudinal direction B of the lead-out path 30 is 90 ° as shown in FIG.
It is not limited to ゜.

Further, it is preferable that the fluid bag is formed with a notch 40 for opening the discharge portion of the discharge path. That is, as shown in FIG. 1, the cut line extending from the notch 40 is the discharge line 3 of the outlet passage 30.
By forming it at a position that intersects with No. 4, the discharge portion 34 of the lead-out path 30 can be opened very easily by tearing from the notch 40 without using an instrument such as scissors. Further, it is preferable to form a notch line 44 where an extension line extended from the notch 40 intersects at a position facing the notch 40 with the lead-out path 30 interposed therebetween. This notch line 4
By forming No. 4, it is possible to prevent the cutting line 42 formed by tearing from the notch 40 by itself stopping at the notch line 44 and forming the cutting line 42 unnecessarily long. Further, on the extension line of the cutout line 44, the peripheral portion 2
It is desirable to form the notch 46 for the notch line in 3. With such a structure, the notch line notch 46 is torn until it is connected to the notch line 44, and the notch 40 is torn from the notch line 44 to open the discharge portion of the lead-out path 30, thereby cutting the line 42, A portion 48 surrounded by the notch line 44 and / or the torn line connecting the notch line 44 and the notch 46 for the notch line is removed.

Further, when the cutout line 44 is formed, the lead-out path 30 of the portion along the cutout line 44 can be freely moved with respect to the fluid bag 20 according to the length of the cutout line 44. Therefore, the outflow work becomes easier. Hereinafter, as shown in FIG. 2, a portion along the cutout line 44 from the discharge portion 34 of the open lead-out passage 30 and the lead-out passage 30 and its adjacent integrated portion (the peripheral portion 22 and the separating portion 38). A part) is called the outflow operation unit 50. When the outflow operation part 50 whose direction and the like can be freely moved is formed, for example, when the contents are transferred to the container, only the outflow operation part 50 is inserted into the mouth part of the container. The contents can be spilled in the closed state, and failure of the transfer work of the fluid can be prevented. In addition to tearing from the notch line notch 46 toward the notch line 44 at the time of outflow work, the same effect can be obtained by previously connecting the notch line 44 to the edge of the peripheral portion 23. . However, if this is the case, the outflow operation unit 50 can move freely before and after the outflow work, so the fit is reduced. In addition, the outlet 3 of the fluid bag 20
It is desirable to form a cut portion 52 having a narrow width at the peripheral portion along the longitudinal direction of 0 near the discharge portion 34 of the outlet passage 30. By forming the cut portion 52, the tip end portion of the outflow operation portion 50 can be thinned, and it becomes easy to insert the outflow operation portion 50 into the mouth of the container or the like.

Further, in the fluid bag of the present invention, it becomes easy to always discharge the contents in a constant amount. That is, if the inner volume of the outlet passage 30 is set to an arbitrary predetermined size, the holding portion 28 is pressed to fill the outlet passage 30 with the contents, and the connecting portion 36 is touched as shown in FIG. By letting the contents inside the outlet passage 30 flow out in a state in which the holding portion 28 and the outlet passage 30 are blocked by suppressing the contents by a predetermined amount, etc., a predetermined amount of contents according to the content integration of the outlet passage 30 flows out. Can be made. Therefore, even when the contents are required one after another in a fixed amount, a measuring cup or the like is not required.
Furthermore, by grading the discharge path, it is possible to carry out several kinds of quantitative flow.

Further, the fluid bag of the present invention has the structure shown in FIG.
As shown in FIG. 7, the outflow of the contents can be easily prevented by bending the outflow operation portion 50 or by further fixing the bent portion with a locking means such as a clip 54 or a tape. Then, in order to allow the contents to flow out again, it is sufficient to remove the locking means and press the holding part 28 when the outflow operation part 50 is straightened. By performing the extremely simple procedure on the outflow operation unit 50 in this manner, the contents will not leak out from the discharge unit of the discharge passage 30 unless a large pressing force is applied to the holding unit 28. Accidents in which the contents leak out will not occur depending on the fall level. Therefore, even after the discharge part 34 is opened and a part of the contents is allowed to flow out, the use is interrupted,
It can be stored, and it is not necessary to discharge the contents all at once, and when necessary, the contents can be made to flow out in a required amount and then transferred to another container. Therefore, even if it is applied to the fluid bag for refilling, it is not necessary to make the internal volume of the holding part smaller than the internal volume of the container to be transferred. In addition, when drinking, it is not necessary to drink all at once, and it can be taken without touching the mouth of the drinker with the discharge part of the discharge path, so it is clean so that other people can drink it at intervals. You can also offer it.

Further, in the fluid bag of the present invention, the internal volume and the overall size are, of course, depending on the use, the type of contents, the easiness of the outflow work of the contents, the design and the like. , The length of the lead-out path 30, the length of the cutout line 44 (the length of the outflow operation portion 50), the width D, the width d, the angle θ1 of the angle of the holding portion 28, the angle θ2 at the connecting portion 36, etc. Adjusted. Further, as the material forming the fluid bag, various materials such as polypropylene and polyethylene can be used according to the purpose. For example, in addition to making it for refrigeration and freezing,
It can also be a retort bag. It can also be vacuum-packed. Further, when a plurality of glass bottles and the like are carried in an outer bag, for example, in a bag, they may collide with each other and may be damaged, but with the fluid bag of the present invention, they collide with each other. Will not be damaged.

Further, when the contents are transferred to the mouth of a narrower container or when it is difficult for the contents to flow out even if the holding portion 28 is pressed, as shown in FIG.
These can be improved by inserting a thin tube 55 such as a straw. In this case, in the fluid bag of the present invention, since the outlet passage 30 is formed in an elongated shape,
It is easy to stably deploy the thin tube 55. In particular, the derivation path 30
By making the tip of the narrower than the connecting portion side, it is possible to suppress the protrusion of the thin tube 55. Further, when the holding portion 28 is expanded in a state where the thin tube 55 is closely inserted in the outlet passage, the fluid can be sucked into the fluid bag from the outside.

Further, the thin tube 55 can be used by inserting it into the lead-out passage 30 from the outside at the time of use. However, the thin tube 55 should be provided in the lead-out passage 30 before use, and the tip of the thin tube should be attached before use. It can also be used by extracting it from the discharge part 34. The thin tube is not limited to one having a rectangular parallelepiped shape in side view, but has a trapezoidal shape in side view by inclining the tip end portion 80 to be thinner than the other end portion as shown in FIG. As shown in FIG. 17, an inclined taper portion 84 may be formed so that the tip end portion 80 is thinner than the other end portion 82. In this way, when the thickness of the thin tube is made different between the tip portion 80 and the other end portion 82, the thin tube is arranged in the outlet passage so that the tip portion 80 is on the discharge section 34 side, and the thin tube is When the discharge passage is moved from the connection portion side toward the discharge portion, the movement of the thin tube is stopped at a position where the size of the discharge passage and the thickness of the thin tube match, and the tip 80 of the thin tube is discharged from the discharge passage. The thin tube further comes into close contact with the lead-out path in a state of protruding from the portion, and the thin tube does not pop out. Also, in this way, the tip 80
By narrowing the side, the fluid bag is pressed so as to allow the fluid to flow out, so that the thin tube arranged in the outlet passage moves to the outlet side of the outlet passage. Further, it is preferable that the thin tube has a distal end portion 80 hermetically sealed before use and that can be opened at the time of use. This is because if the tip portion 80 is sealed, the thin tube can be easily moved to the discharge portion side of the lead-out path by pressing the fluid bag so that the fluid flows out. Further, as shown in FIG. 18, the enlarged diameter portion 8 is formed on one end or both ends of the thin tube.
Even when the thin tubes 6 and 88 are formed, the ease of movement of the thin tube in the lead-out path and the certainty of stopping the thin tube at a predetermined position can be enhanced.
