Description

Spout outlet member and packing bag using it {SPOUT MEMBER AND PACKAGING BAG UTILIZING SAME}

The present invention relates to a packaging bag, in particular a packaging bag for receiving a landscape enteric nutrient or a landscape entertaining fluid, etc., and extracts a packaging bag that is opened by partially cutting the periphery of the sealed film piece or forming an opening. The present invention relates to a spout outlet member attached to a pouch having a spout, and a pouch using the same.

Scenic enteral nutrients (hereinafter referred to as nutrients) or landscape entertaining fluids (hereinafter referred to as fluids) can be accommodated in various packaging containers such as cans, paper containers, pouches, bottles, etc. It is excellent in sealing property and handleability, and is used a lot. As a pouch type, it usually has a spout, and a tube is connected to the spout for administration. Especially, in the case of nutrients and liquids, it is diluted according to the condition of the patient at the time of initial introduction and used to supply insufficient medicine and water during stability. Is common. In such a case, a separate member such as a molding member is previously attached to the periphery of the packaging bag and used as an injection hole (see Patent Document 1 below), but the cost is particularly large as the cost of materials or attachment is high or a separate member is inserted in the periphery. Stacking packaging bags, such as the case of forming an injection hole, causes problems such as a large volume, making it difficult to handle. Thus, a structure in which a portion of the packaging bag is cut out to form an injection hole is often used (see Patent Document 2 below).

However, in the case of a structure in which a portion of the packaging bag is cut out to form an injection hole, the support of the pouch tends to be unstable without a reliable support means for handling the pouch with the liquid contents contained therein. It is difficult to cut a part or to supply water or chemicals, so that the bag may be dropped or inclined to spill the contents, and the inlet may be contaminated or opened more than necessary by contacting the inside of the bag. There was also a problem with sanitation.

In addition, the closing means such as zipper seals, which are pre-installed in the openings, may be disengaged due to internal pressure by the contents during storage or transportation, and the contents adhere to the engaging portions, resulting in insufficient meshing or contamination of the contents. For this reason, it has been developed that an easy-fill part is provided which isolates the closing means from the contents before opening and is peeled off at the time of opening (see Patent Applications 3 and 4 below).

Conventionally, the easy peeling part is formed by bonding the film pieces constituting the packaging bag to each other by a peeling seal, but when the internal pressure is applied to the inside of the packing bag by dropping or the like during storage or transportation, the easy peeling part is peeled off. You may not be able to accomplish it.

In addition, an easy peeling part may be provided in a part to be an opening, and the purpose may be to indicate the opening by peeling off the easy peeling part or to reduce the internal pressure due to the rupture of the easy peeling part (see patent applications 5 and 6 below). The peeling of the easy peeling part was not prevented by the influence of.

In addition, in order to facilitate the ejection of the containment, there is a lot of use of another member, such as a molding member, previously attached to the periphery of the packaging bag as the ejection outlet member. If the spout member is exposed to the outside of the pouch before opening, such as during transportation or storage, the spout member may be exposed to outside air, dust, etc., and may be contaminated. Also, the spout member may permeate H ₂ O, O _2, etc. Oxidation or deterioration may occur, such as vitamin destruction. Thus, since a problem arises easily in hygiene control or quality control, there is a case where a spout member is sandwiched between film pieces (see Patent Documents 7, 8 below).

However, all the ejection outlet members of the packaging bag described in the following patent document may have a finger or the like coming into contact with the ejection outlet at the time of opening, and the sewing outlet member can be sewn after opening the ejection outlet member. Since it has to be taken out and used, there is a problem in handling or contamination prevention.

Moreover, even when it puts in a packaging bag, a spout member is easy to move, and it is easy to be damaged by an external shock etc.

Indicates an enlarged view. 14-16, the main body part of the packing bag 53 carries out the periphery part 54 of two film pieces 53a, 53a by fusion | melting, etc., and makes it the seal part (it is shown with the diagonal line in FIG. 14), and the accommodating part 55 is formed. . Filling of the contents is carried out by forming a part of the periphery of the packaging bag as another part as the unsealed part, and then filling the unreceived part as a filling port to seal the unsealed part. 20 is a front view of the spout member as an example of the embodiment of the present invention, FIG. 21 is a sectional view seen from the front direction of the spout member of FIG. 20, and FIG. 22 is an X-X cross-sectional view of the spout member of FIG. 20, FIG. 23 (a) is a front view of the cap part after opening the spout member of FIG. 20, FIG. 23 (b) is a bottom view of the cap part of FIG. 23 (a), and FIG. 23 (c) is a cap of FIG. 23 (a). 24 (a) is a front view of the ejection part after opening the ejection outlet member of FIG. 20, and FIG. 24 (b) is a bottom view of the ejection part of FIG. 24 (a).

The peripheral part 2 of the packaging bag 1 is provided with the injection part 3 and the pouring part 4. The injection part 3 is installed in the upper edge part 2a of the periphery part 2, and widens the both end seal parts 2b and 2b of the upper edge part 2a, and the inside of a packaging bag becomes a shape which protrudes upwards, and becomes an injection hole after opening. The injection part 3 is provided with the easy opening part 6 which crosses from the seal part to the opposite thread part from the seal part which becomes an injection hole, and the upper part of the film piece which pulled along the easy opening part 6 by grasping the upper side of the easy opening part 6 (peripheral part) By cutting off a portion), an opening by the unsealed portion is formed to become the injection port 3a, and the injection portion is opened. The easy opening part 6 is formed by the half cut by laser irradiation. And if the easy opening part 6 is formed so that the traces of the two film pieces 1 a and 1 a which form the packaging bag 1 may differ, each film piece may shift | deviate mutually the position of the opening edge cut out by the easy opening part 6, respectively. As it is possible, each film piece is easy to grasp, and it is easy to open an injection hole. In addition, in the packaging bag 1 of FIG. 1, the linear zipper part 7 and the easy-fill part 8 which are free to open and close are formed in the line which connects the holes 5 and 5 mentioned later of a non-room part. The zipper on the line 7 is installed to close the inlet after the injection operation so as to facilitate hygiene management, and the easy peeling part 8 is installed to increase the sealing property before opening the inlet. Peeling part 8 is peeled off and an injection hole is opened completely.

The packaging bag 1 is formed with two holes 5 and 5 penetrating through the film pieces between the portions 2b and 2b of the upper edge part, which is the periphery of the vicinity of the injection section 3, with the portion to be the injection port 3a interposed therebetween. The holes 5 and 5 are suspending means capable of suspending the packaging bag. As shown in Fig. 3, the ejection section 4 is placed at the bottom by hanging the pouch 1 by hanging a jig (indicated by reference numeral 20 in Fig. 3) on one of the holes 5 and 5 at the time of ejection from the ejection section described later. This facilitates the ejection of the object from the ejection section 4 (indicated by the triple arrows in the figure). In addition, it is also possible to facilitate the replenishment of water and drugs from the injection port 3a formed by the opening of the injection section 3 disposed above. In addition, the holes 5 and 5 may also be finger supporting means for ensuring the handling of the bag by the size of the finger. Specifically, for example, when opening the injecting unit 3, the thumb 1 is placed on one side of the holes 5 and 5 and the other finger (for example, an index finger) is placed on the other side, and the pouch 1 is placed with one hand and the infusion unit 3 is upward. As described above with the other hand, the hand can be opened by cutting at the easy opening, and the injection port 3 a can be formed as shown in FIG. The water and the medicine can be supplied from the injection port 3a thus formed as indicated by the arrow in Fig. 4.

In the present invention, as described above, by providing two or more holes with a portion to be the inlet as a means for supporting the bag by the fingers of the bag, it is possible to reliably support the vicinity of the inlet of the bag. As it can be kept open, it is easy to disperse moisture, dropping or tilting the packaging bag, contaminating the inlet by contacting the inside of the packaging bag, and opening more than necessary. Problems can be reduced. In addition, by supporting the hole with a suspending means capable of suspending the packaging bag, the supporting means can be easily formed without adding a member or the like separately. Moreover, while using one hole as a means for suspending, a finger can be held and supported by the other hole, and opening operation can be performed stably.

The packaging bag of the present invention is a configuration in which the injection portion is not mounted with a separate member such as a molded part on the periphery, but a part of the periphery of the sealed film piece is formed to form an opening by the unseal part to form the injection port. When the injection port is made into a large diameter, the member becomes large if it is a molded article, and the volume becomes uncomfortable when stacked or stored and transported either before or after accommodating the contents. It is easy to store and transport, and a packaging bag having a large diameter inlet can be produced at low cost. The composition of the infusion portion as described above tends to be unstable at the time of opening, since the film piece is pulled by hand or cut with scissors, etc., compared to the case of using a molded article, and the packing bag is dropped or tilted even when replenishing moisture. It is easy to cause a problem such as spilling of the receiving material, or a problem of contaminating the injection hole by contacting the inside of the packaging bag, but in the present invention, since two or more holes are formed between the portions to be the injection hole, stable support is possible.

At least two holes may be formed between the holes serving as injection holes, but for example, three or more holes may be provided in consideration of differences in the size of the packaging bag and the size of the hand. In addition, the arrangement of the holes is not particularly limited as long as the finger can stably support the portion that serves as the injection port therebetween.

The shape of the hole is not particularly limited as long as it is possible to hang a finger at the time of handling the packaging bag, and a circular or circular shape hole such as the hole 5 in the packaging bag of FIG. 1 or a slit shape as shown in FIG. Denoted by the symbol 12). The size of the hole is preferably in the range of 8 to 30 mm in diameter in the case of a circular or circular shape, and in the range of 30 to 60 mm in the length in the case of the slit shape, because it is not a problem in strength and is easy to hold a finger and is easy to support. Do. Moreover, as shown in FIG. 6, the state which does not carry the film piece of a periphery of a hole may be sufficient. In FIG. 6, the part (not shown) which is not carried is represented by 16. In FIG. Since the film part of the periphery of the hole is not threaded, and the non-real part is not as strong as the thread part and is flexible, the end of the film piece is bent even when the finger is hooked, and the edge of the film becomes hard to directly touch the finger, so that the finger does not hurt. The width of the unsealed portion is appropriately set according to the size of the packaging bag and the hole. In addition, as part of a periphery of a hole is left without making a hole penetrating a film piece, as shown in FIGS. 7 (a)-(c), in the perforation line (Fig. 7 (a)-(c), reference numerals 13 and 13). Formed by a '13' 'or as a half cut (indicated by the symbol 13' '' in Fig. 7 (d)) as shown in Fig. 7 (d), as shown in Fig. 7 (e). At the time of use, the cut line or the half cut may be broken so that a part of the film piece (indicated by reference numeral 14 in Fig. 7 (e)) is connected to the packaging bag body. The film piece connected to the packaging bag main body is inserted, and a finger becomes hard to touch the edge part of a film piece, and a finger does not hurt. When the position where a part of a film piece is connected to a packaging bag main body is made into the upper part, it is supported by the inserted part of a film piece, and it is more preferable. A part of the hole may be a through hole so as to break the cut line or the half cut.

In addition, the hole may have a shape in which the portion that becomes the upper edge part is convex downward when used as a supporting means by the finger. The above-mentioned shape is preferable because the convex upper edge part is bent when supporting with a finger, and it is supported by the bent part of a film piece, and it becomes difficult for a finger to touch the edge part of a film piece, and a finger does not hurt. Moreover, the unsealed part which the film piece of the said hole upper edge part does not seal may be sufficient. If the hole upper edge part film piece is not sealed, since the unthreaded part is not strong and flexible compared with the thread part, the convex upper edge part tends to bend and is more preferable.

12 and 13 show an embodiment in the case where the hole is a shape where the upper edge portion becomes convex downward when used as a support means by a finger. The front view of the packaging bag which is another example of embodiment of this invention, and FIG. 13 is an enlarged view of the hole in the packaging bag of FIG. In addition, the packaging bag of FIG. 12 is embodiment in which the shape of the hole 5 in the packaging bag of FIG. 1 differs, and the part which has a structure which overlaps with the packaging bag of FIG. 1 is shown using the same code | symbol. In the packaging bag of Fig. 12, the hole 50 has a shape in which the portion 50a, which becomes the lower edge, is semicircular when used as a supporting means by the finger, and the portion 50b, which becomes the upper edge, is convex downward. 51). In addition, the film piece of the upper edge part of the hole 50 is set as the unsealed part 52. In the case of the configuration as described above, the hole shape other than the upper edge portion is not particularly limited as long as the portion of the upper edge portion becomes convex downward when used as a support means of the finger of the hole. Oval, square, etc., or a combination of them can be made. Moreover, it does not specifically limit in the range which does not impair the effect of the convex shape of an upper edge part, and the range of an uneven part also bend | folding, and the edge part of a film piece becoming hard to touch a finger.

In the present invention, in order to increase the stability when the packaging bag is supported by a finger and to facilitate handling, the rigidity of the line connecting the holes interposed between the portions that serve as the injection holes in the injection portion is larger than the other portions. desirable. This configuration makes the film piece of the packaging bag main body less likely to be wrinkled at the time of opening, which facilitates the opening operation as well as opening and holding it in a stable manner by simply pressing the inlet lightly from side to side with a finger inserted into a hole as a supporting means after opening. It becomes easy to do it. After the injection operation, the injection port is returned to its original state simply by loosening the force of the finger, which is also preferable for hygiene management.

As described above, as a method of increasing the linear rigidity connecting the holes interposed between the portions to be the injection holes with each other, forming a linear zipper opening and closing free line on the line connecting the holes between the portions to be the injection holes. A method is mentioned. The linear zipper portion has the advantage of being able to close the injection port after replenishment from the injection hole, thereby facilitating hygiene management, but at the same time, the rigidity of the ship can be enhanced. In addition, you may attach the member which is higher in rigidity than the film piece which comprises a packaging bag to the said line | wire in strip shape.

The packaging bag of the present invention has a spout portion separate from the injection portion in the peripheral portion 2. Since the packaging bag is suspended by the suspending means at the time of dispensing, it is necessary to provide a dispensable arrangement at the time of suspending, and it is preferable to provide the dispensing part at a position facing the suspending means, that is, at a position facing the injection port. In FIG. 1, the lower edge part of the packaging bag main body is cut out inside, and the ejection part 4 is provided in one side of the cut part. Hanging the pouch 1 by hanging the jig on one side of the hole 5 of the suspending means, which also serves as the support means, the ejection part 4 is disposed almost vertically downward, and the ejection of the contents at the ejection part 4 and the inlet part 3 arranged above. The replenishment from the inlet 3a formed by opening becomes easy. In the packaging bag of the present invention, as described above, it is preferable that at least one of the holes is disposed so that the ejection portion is almost vertically downward when suspended as the means for hanging the holes.

In the packaging bag 1 of FIG. 1, the ejection portion 4 is formed by attaching the base portion to the packaging bag body by heat bonding or the like so that the tip of the molded ejection outlet member 4a protrudes from the packaging bag body.
