Description

  The present invention relates to a hanging bag container for storing a fluid filling such as enteral nutrient.

Conventionally, fluid foods and infusions such as enteral nutrients containing vitamins and amino acids are filled in flexible hanging bag containers and administered to patients orally or enterally. .
As shown in FIG. 8, the hanging bag-like container has a front and back surface portion 20 and both side surface gusset portions 21 and 22 of a flexible film, and both side surface gusset portions 21 and 22 are provided on both sides of the front and back surface portion 20. A bag body 23 that is folded and bonded around the front and back surface portions 20 and both side gusset portions 21 and 22 and formed into a bag shape; and an injection tool 24 that is interposed and bonded to the upper seal portion 20a of the front and back surface portions 20; A suspension hole 25 formed in the upper seal part 20a on the side of the injection tool 24, and a pouring tool 26 interposed and bonded to the center in the width direction of the lower seal part 20c of the front and back surface part 20 are provided. The folding lengths of the side gusset portions 21 and 22 are both formed equally.

Specifically, both film pieces forming both side gusset portions 21 and 22 have the same width, are folded at the center portion in the width direction, and are inserted on both sides of the front and back surface portions 20. Both sides of both side gussets 21 and 22 are bonded to the sides of the front and back surfaces 20, respectively, and upper and lower sides of the side gussets 21 and 22 are bonded to both sides of the upper and lower sides of the front and back surfaces 20 respectively. Yes. Furthermore, the center area | region of the upper side of the front-and-back surface part 20 is adhere | attached in the state which inserted | pinched the injection tool 24.
Therefore, the front and back surface portions 20 and both side surface gusset portions 21 and 22 are bonded to the width direction both side regions of the upper seal portion 20a of the bag body 23, and the width direction center region of the upper seal portion 20a sandwiches the injection tool 24. The front and back surface portions 20 are bonded, and a hanging hole 25 is formed.

  The hanging bag-like container is filled with fluid filling such as enteral nutrients, dilution water, and the like through the injection tool 24. The hanging bag-like container is used by hanging and supporting a hanging hole 25 on a hooked member such as a hook and attaching a hose or the like to the pouring tool 26. By such hanging use, the filling material is poured out from the pouring tool 26 provided at the center of the lower seal portion 20c of the bag-like container and can be administered to the patient.

However, when the conventional bag-like container is suspended from the hooked member, the bag-like container is tilted. Therefore, when the filling material is reduced, a filling material that is not poured out from the pouring tool 26 is generated. As a result, there is a problem that a relatively large amount of filling remains in the container.
Specifically, in the conventional bag-shaped container, the hanging hole 25 and the relatively heavy infusion tool 24 are not provided in the central portion in the width direction of the bag body 23, and the hole 25 is The side surface gusset portion 21 is provided, and the injection tool 24 is provided near the other side surface gusset portion 22. Therefore, when the hole 25 is hooked on the hooked member and the filled bag-like container is hung, the weight on the other side gusset part 22 side becomes heavy with respect to the hole 25, so that the balance on both sides of the container cannot be achieved. The bag-like container is inclined.
In this regard, for example, if the hole 25 for suspending is formed close to the central portion in the width direction of the upper seal portion 20a of the bag body 23, the inclination of the bag-like container at the time of suspending can be significantly suppressed.
However, the bag-like container injection tool 24 must be interposed between the front and back surface portions 20 and bonded (the front and back surface portions 20 and the side gusset portions 21 and 22 are bonded due to the structure of this type of bag-shaped container. The injection tool 24 cannot be bonded to both side regions of the upper seal portion 20a, and the injection tool 24 must be bonded to the central region of the upper seal portion 20a). Further, the suspension hole 25 must be formed in the central region of the upper seal portion 20a.
Therefore, the injection tool 24 and the hole for suspension must be arranged in the width direction in the central region of the upper seal portion 20a, which is a limited region.
However, since the bonded portion 27 of the injection tool 24 is wide, the bonded portion 27 of the injection tool 24 is interposed in most of the central region of the upper seal portion 20a. Since the hole 25 for suspending must be formed avoiding the adherend portion 27, the conventional bag-like container has the hole 25 for suspending in the center in the width direction of the upper seal portion 20 a of the bag body 23. It cannot be formed in the part.

  As a hanging bag-like container of this type, Japanese Patent Laid-Open No. 2000-6999 discloses a configuration in which a side gusset portion is provided only on one side of the front and back surfaces. However, this publication does not disclose the above-mentioned problem that the bag-like container is tilted when suspended and the means for solving it. Moreover, since the side gusset part is provided only in the one side, the capacity | capacitance of a bag-shaped container cannot fully be secured for the hanging bag-shaped container of this gazette description.

JP 2000-6999 A

  Therefore, an object of the present invention is to provide a hanging bag-like container that makes it difficult for the whole container to tilt when suspended and uses the hole for suspension, and that can ensure a sufficient capacity.

  In view of the above problems, the present invention has a front and back surface portion and both side surface gusset portions of a flexible film, and both side surface gusset portions are folded on both sides of the front and back surface portions and around the front and back surface portions and both side surface gusset portions. A bag body formed in a bag shape by bonding, an injection tool intervened and bonded to the upper seal portion of the front and back portions, and a hole for suspension formed in the upper seal portion of the front and back portions, The folding length of one side gusset portion is formed larger than the folding length of the other side gusset portion, the injection tool is bonded to the other side gusset portion, and the hole for hanging However, the present invention provides a hanging bag-like container that is formed at or near the center in the width direction of the upper seal portion.

Since the bag main body of the said hanging bag-shaped container is provided with the side surface gusset part on both sides of the front and back surface part, the capacity | capacitance filled with a filling can fully be ensured.
Furthermore, since the folding length of one side gusset portion is formed larger than the folding length of the other side gusset portion, one side gusset portion side swells greatly when filled with a filler. For this reason, one side gusset portion side is heavier than the other side gusset portion side, with the width direction center portion of the bag body as a reference.
On the other hand, since the injection tool of the bag-like container is bonded to the other side surface gusset portion, the weight of the injection device is added to the other side surface gusset portion side with respect to the width direction center portion of the bag body.
Therefore, the filled bag-like container is based on the center part in the width direction of the bag body, and the weight of one side gusset part due to the above folding length and the other side gusset part side caused by adhesion of the injection device The weight is roughly balanced.
Such a bag-like container in which the weights on both sides are balanced is formed such that the suspension hole is located at the center in the width direction of the upper seal part or in the vicinity thereof. When the container is suspended and used, the entire container is difficult to tilt.

  In addition, the present invention has a bag by having front and back surfaces and both side gusset portions of a flexible film, the both side gusset portions are folded on both sides of the front and back surfaces, and the periphery of the front and back surfaces and both side gusset portions are bonded. One side gusset portion having a bag body formed in a shape, an infusion tool interposed and bonded to the upper seal portion of the front and back surfaces, and a hole for suspension formed in the upper seal portion of the front and back surfaces Is formed larger than the weight of the other side gusset portion, the injection tool is bonded to the other side gusset portion, and the suspension hole is formed at the center in the width direction of the upper seal portion or There is provided a hanging bag-like container formed in the vicinity thereof.

Similarly, the hanging bag-like container is provided with side gusset portions on both sides of the back surface portion, so that a sufficient capacity for filling the filling material can be secured.
Furthermore, since the weight of one side gusset portion is larger than the weight of the other side gusset portion, the side gusset portion side of one side is the other side gusset portion with respect to the center in the width direction of the bag body. Heavier than the club side.
On the other hand, since the injection tool of the bag-like container is bonded to the other side surface gusset portion, the weight of the injection device is added to the other side surface gusset portion side with respect to the width direction center portion of the bag body.
Accordingly, in the filled bag-like container, the weight on the one side gusset portion side and the weight on the other side gusset portion side resulting from the adhesion of the injection tool are roughly set with respect to the center portion in the width direction of the bag body. To balance.
Such a bag-like container in which the weights on both sides are balanced is formed such that the suspension hole is located at the center in the width direction of the upper seal part or in the vicinity thereof. When the container is suspended and used, the entire container is difficult to tilt.

  The hanging bag-like container according to the present invention can ensure a sufficient capacity. In addition, the hanging bag-like container is not easily tilted when hung using the hanging holes, and therefore can be suitably used as a bag-like container for administering a liquid food or the like to a patient. .

Hereinafter, the present invention will be specifically described with reference to the drawings.
<First Embodiment>

Indicates.

The both side gusset portions 5 and 6 folded on both sides of the front and back surface portions 2 and 3 have a fold length L5 of one side gusset portion 5 larger (longer) than a fold length L6 of the other side gusset portion 6. Is formed.
The ratio of the folding length L5 of one side gusset part 5 and the folding length L6 of the other side gusset part 6 is not particularly limited, but when the filled bag-like container 1 is suspended to reduce the filling, Since the inclination of the bag-like container 1 can be satisfactorily prevented while maintaining the balance on both sides, the folding length L5: folding length L6 is preferably about 5: 4 to 5: 1. : It is more preferable that it is formed in the order of 2 to 3: 1. Specifically, in the case of the bag body 10 with the widths of the front and back surface portions 2 and 3 being about 150 to 200 mm and the height being about 170 to 220 mm, the folding length L5 of one side gusset portion 5 is about 40 to 80 mm, It is preferable that the folding length L6 of the side gusset portion 6 is about 20 to 30 mm.

The front surface portion 2, the back surface portion 3 and the side surface gusset portions 5 and 6 are made of flexible film pieces having a predetermined shape, and the inner peripheral surfaces of the portions 2, 3, 5 and 6 are bonded to each other (a film having heat sealing properties). When used, the bag main body 10 is formed by bonding).
Therefore, an upper seal portion 10a, both side seal portions 10b, and a lower seal portion 10c are formed around the bag body 10.

The front and back surfaces 2 and 3 are made of, for example, a rectangular film piece. The both side gusset portions 5 and 6 are made of a rectangular film, and the width of the film constituting one side gusset portion 5 is longer than the width of the other side gusset portion 6.
Note that the upper and lower corner portions of the side surface gusset portions 5 and 6 are notched as shown in FIG. 2 in order to partially bond the front and back surface portions 2 and 3.
The films constituting the gusset portions 5 and 6 on both sides are folded in the longitudinal direction at the central portion in the width direction, and inserted on both sides of the front and back portions 2 and 3 with the fold line inside.
Both side sides of one side gusset portion 5 are respectively bonded to one side of the front and back surface portions 2 and 3, and upper and lower sides of one side gusset portion 5 are one side regions of upper and lower sides of the front and back surface portions 2 and 3 ( It is bonded to the upper and lower sides in the width direction of the upper and lower sides 2 and 3). Similarly, both sides of the other side gusset 6 are bonded to the other sides of the front and back sides 2 and 3, respectively, and the upper and lower sides of the other side gusset 6 are on the other sides of the upper and lower sides of the front and back sides 2 and 3, respectively. It is bonded to the region (except for the central region in the width direction of the upper and lower sides of the front and back surface portions 2, 3). Accordingly, the side gusset portions 5 and 6 are not interposed in the central region in the width direction of the upper seal portion 10a and the lower seal portion 10c of the bag body 10.
In addition, in order to make the lower side of the interior (storage part) of the bag body 10 inclined and to easily guide the filler to the dispensing tool 8 side, the lower seal part 10c of the bag body 10 is as shown in FIG. It is bonded to the pouring tool 8 so as to be inclined downward.

The center region in the width direction of the upper seal portion 10a of the front and back surface portions 2 and 3 is bonded with the injection tool 7 interposed therebetween, and a hole 9 for suspending is formed.
The injection tool 7 and the hole 9 for suspending are provided side by side in the central region in the width direction where the side gusset portions 5 and 6 are not bonded, among the upper seal portions 10a of the front and back surface portions 2 and 3. The injection tool 7 is provided near the other side gusset portion 6 having a short folding length, and the suspension hole 9 is located in the vicinity of the central portion in the width direction of the upper seal portion 10a. It is formed in a shape. The specific formation position of the hole 9 is appropriately set according to the degree of folding length of the side surface gusset portions 5 and 6, the weight of the injection tool 7, and the like, and is not particularly limited. In the case of the bag body 10 having a width of 2, 3 to 150 to 200 mm and a height of about 170 to 220 mm, in order to balance both sides, it is preferably within about 25 mm from the center in the width direction of the upper seal portion 10a, and further 20 mm Within the range is more preferable.
Moreover, although the shape of the hole 9 is not specifically limited, it is usually formed in a circular shape, and the opening diameter is usually about 3 to 15 mm.

The injection tool 7 has a body portion 71 having a through-hole (not shown) communicating with the inside of the bag body 10 and having an adherend portion 73 interposed and bonded to the front and back surface portions 2 and 3, and the body portion 71. And a cap 72 attached to and detached from the inlet.
The pouring tool 8 has a through-hole (not shown) communicating with the inside of the bag body 10 and has a bonded portion 83 that is bonded to the front and back surface portions 2 and 3, and a hose can be easily attached to the lower end portion. A tapered surface 82 for insertion connection is formed. The pouring tool 8 may be provided with a spout in advance and provided with a cap for sealing the spout, or may be capable of forming a spout during use. The pouring tool 8 is bonded to the central portion in the width direction of the lower seal portion 10c.

The injection tool 7 and the pouring tool 8 are not particularly limited, and a molded product made of various synthetic resins, metals such as aluminum can be used, but can be easily attached to the bag body 10 by heat fusion. Therefore, it is preferable that at least the peripheral surfaces of the bonded portions 73 and 83 can be heat-sealed to the inner surfaces of the front and back surface portions 2 and 3. Examples of the injection tool 7 and the dispensing tool 8 include synthetic resin molded products such as polyethylene and polypropylene.
The weight of the injection tool 7 is usually about 3 to 10 g. Moreover, the width | variety of the to-be-adhered part 73 of the injection tool 7 has a preferable thing of about 20-50 mm.

The film which comprises the front and back surface parts 2 and 3 and the side gusset parts 5 and 6 is not specifically limited, The conventionally well-known thing used for this kind of bag-shaped container can be used. For example, as the film, a laminated film having a sealant layer on the innermost surface of the base film can be used. Moreover, the laminated | multilayer film by which various functional layers, such as a light shielding layer, an ultraviolet absorption layer, a gas barrier layer, are laminated | stacked as needed can also be used.
Examples of the base film include one or more selected from polyesters such as polyethylene terephthalate, polyolefins such as polypropylene and cyclic olefin, polystyrenes such as polystyrene, and thermoplastic resins such as polyvinyl chloride, polyamide, and polycarbonate. It is preferable to use a polyester-based film such as polyethylene terephthalate because it can be used for general purpose, has heat resistance, and is excellent in strength. As such a base film, a film formed from a resin composition kneaded with an ultraviolet absorber, a film infiltrated with an ultraviolet absorber, or the like can also be used.

The sealant layer is not particularly limited as long as it can be heat-sealed. For example, linear low-density polyethylene, high-density polyethylene, metallocene-catalyzed polyethylene such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, or the like is used. be able to. The sealant layer can be laminated, for example, on the inner surface side of the base film by a dry lamination method or the like.
A film provided with a sealant layer is preferable because the bag body 10 can be easily formed by heat sealing or the like. However, when the bag body 10 is not formed by heat sealing, a film having no sealant layer is used. It is also possible to use it.
The film thickness of the base film and the sealant layer is usually about 50 to 200 μm.

Examples of the light shielding layer include printing on a base film an ink that blocks a visible light region (ink exhibiting yellow, vermilion, orange, red, etc.), and providing a metal vapor deposition layer on the base film.
For the UV absorbing layer, organic UV absorbers such as benzotriazole compounds, benzophenone compounds, cyanoacrylate compounds, salicylate compounds, inorganic UV blocking agents such as titanium oxide, zinc oxide, cerium oxide, etc. are suitable. For example, it may be dispersed and dissolved in a binder and coated on a base film.

The said hanging bag-shaped container 1 is provided in the state which filled and enclosed the inside with the filling tool 7, for example.
When the hanging bag-like container 1 of the present invention is used for medical purposes, for example, liquid food is enclosed as a filling. When the liquid food is administered to a patient, the filling material is replenished by adding a diluent or the like through the injection tool 7 as necessary.
As shown in FIGS. 3 and 4, the bag-like container 1 of the present invention in which both side gusset portions 5 and 6 are provided on both sides of the front and back surface portions 2 and 3 has both side gusset portions 5 and 6 at the time of filling. Since it swells, it has a relatively large capacity and can be sufficiently filled.

As shown in FIG. 5, the filled bag-like container 1 is formed by inserting a suspension hole 9 into a hooked member 4 such as a hook, thereby providing a support base (FIG. 5). (Not shown) is supported in a suspended state.
And the liquid food poured out from the pouring tool 8 can be administered to a patient by attaching a hose etc. to the pouring tool 8 of this bag-shaped container.

Since the folding length L5 of one side gusset portion 5 is formed larger than the folding length L6 of the other side gusset portion 6, the hanging bag-like container 1 of the present invention has a filled bag shape. As for the container 1, one side gusset part 5 side will swell greatly. Accordingly, the side gusset portion 5 side on one side is heavier than the side gusset portion 6 side on the other side with respect to the center portion in the width direction of the bag body 10.
On the other hand, since the injection tool 7 of the bag-like container 1 is bonded to the other side surface gusset part 6, the injection tool is provided on the other side surface gusset part 6 side with respect to the center part in the width direction of the bag body 10. A weight of 7 will be added. In addition, the weight of a hose attached to the pouring tool 8 is added.
Therefore, since the weight of the side gusset portion 5 side and the other side gusset portion 6 side of the filled bag-like container 1 is roughly balanced with respect to the center portion in the width direction of the bag body 10, The filled bag-like container 1 can be suspended with almost no inclination by being suspended in the suspension hole 9 formed in the vicinity of the central portion in the width direction of the upper seal portion 10a.
Therefore, even if the filling material filled in the bag-like container 1 is reduced, the filling material is unlikely to remain in the corners of the bag-like container 1, and the filling material in the bag-like container 1 is poured out from the pouring tool 8. can do.
In particular, since the lower seal portion 10c of the bag body 10 is inclined so as to be lowered toward the pouring tool 8, the filling gradually decreasing tends to gather on the pouring tool 8 side, and the remaining little filling is poured. The dispensing tool 8 can be surely poured out.

Second Embodiment
The second embodiment relates to a bag-like container in which the weight of one side gusset part 5 itself is larger than the weight of the other side gusset part 6 itself. In the following, portions different from those of the first embodiment will be mainly described, description of similar configurations and effects may be omitted, and terms and figure numbers may be used.

As shown in FIGS. 6 and 7, the hanging bag-like container 1 of the present embodiment includes front and rear surface portions 2 and 3 made of a flexible film and flexible films folded on both sides of the front and back surface portions 2 and 3. The bag body 10 having both side gusset portions 5 and 6 and the periphery of the front and back surface portions 2 and 3 and the side surface gusset portions 5 and 6 are bonded, and the upper seal portion 10a of the front and back surface portions 2 and 3 are interposed. The injection tool 7 bonded to the upper surface, the pouring tool 8 bonded to the lower seal portion 10c of the front and back surface portions 2 and 3, and the hole for suspension formed in the upper seal portion 10a of the front and back surface portions 2 and 3 9.
The injection tool 7 is adhered to the other side gusset portion 6 and the suspension hole 9 is formed in the vicinity of the central portion in the width direction of the upper seal portion 10c.

The both side surface gusset portions 5 and 6 are formed to have substantially equal folding lengths L5 and L6. In this respect, it is the same as the structure of the conventional bag-shaped container with the both side gussets.
As described above, in the bag-like container 1 of the present embodiment, the side gusset portions 5 and 6 are formed of a film having the same width, but the film constituting one side gusset portion 5 is the other side gusset portion. A film that is heavier than the film constituting 6 is used.
In the first embodiment, the one side gusset portion 5 is made of a film having a large folding length L5. Therefore, the weight of the one side gusset portion 5 itself is larger than the weight of the other side gusset portion 6 itself. Can also be said to be large. In this regard, the bag-like container 1 of the present embodiment uses a film in which the weight of one side gusset portion 5 itself is clearly larger than the weight of the other side gusset portion 6 itself, while using a film of substantially the same width. It becomes.

Examples of the heavy film include a film having a large weight per unit area (the film itself is heavy), a film having a weight attached to a part thereof, and a film having a large weight per unit area is generally used. .
For example, as a film constituting one side gusset part 5 using a laminated film in which sheets having a large weight per unit area are laminated as compared to a resin film having the same thickness as a film constituting one side gusset part 5 Except for not having a sheet having a large unit weight, use of a laminated film having the same structure is exemplified. As a sheet having a large weight per unit area compared to a resin film of the same thickness, for example, a metal sheet such as an aluminum foil, a sheet coated with ink containing metal fine particles, and a film formed by blending metal fine particles Among them, it is preferable to use a laminated film such as an aluminum foil having a thickness of 15 to 20 μm or a polyester film having a large specific gravity and a large thickness (for example, about 25 μm).

Since the weight of the one side gusset part 5 is formed larger than the weight of the other side gusset part 6, the hanging bag-like container 1 is based on the width direction center part of the bag body 10 as a reference. One side gusset portion 5 side is heavier than the other side gusset portion 6 side.
On the other hand, since the injection tool 7 of the bag-like container 1 is bonded to the other side surface gusset part 6, the injection tool is provided on the other side surface gusset part 6 side with respect to the center part in the width direction of the bag body 10. A weight of 7 will be added.
Therefore, in the filled bag-like container 1, the weights of the one side gusset part 5 side and the other side gusset part 6 side are roughly balanced with reference to the center part in the width direction of the bag body 10. Similarly, the filled bag-like container 1 can be suspended with almost no inclination.

<Other embodiments>
The hanging bag-like container 1 of the present invention is not limited to the examples illustrated in the above embodiments, and can be appropriately changed within the range intended by the present invention.
For example, the first embodiment and the second embodiment may be combined. Specifically, as the constituent film of one side gusset portion 5, the film itself is heavier than the constituent film of the other side gusset portion 6, and the shape thereof is more than the film of the other side gusset portion 6. It is also possible to use a wide film (a film with a long folding length).

In the first and second embodiments, the suspension hole 9 is provided in the vicinity of the central portion in the width direction of the upper seal portion 10a, but is provided in the central portion in the width direction. Also good.
Furthermore, although the injection tool extraction tool 8 is provided in the width direction center part of the lower seal part 10c of the bag main body 10, you may be provided in the vicinity position of the width direction center part, or other positions.
