Description

[0001] SPOUT MEMBER AND PACKAGING BAG UTILIZING SAME [0002]

The present invention relates to a packaging bag, in particular, a packaging bag for accommodating a landscape napkin or a nutrient for landscape or landscape, a packaging bag which is opened by forming a part of a periphery of a sealed film piece to form an opening, A main outlet member attached to a packaging bag having a main outlet and a packaging bag using the same.

It is used in various packaging containers such as cans, paper containers, pouches, bottles and the like, but among them, pouch type pouches (pouches) Are widely used because of their excellent sealing properties and handling properties. The pouch type is generally equipped with a main outlet and a tube connected to the main outlet. However, in the case of nutrients or liquid type, it is diluted in accordance with the patient's condition at the time of initial introduction. It is common. In this case, a separate member such as a molded member is previously attached to the peripheral portion of the package bag to form an injection port (see Patent Document 1 below), but the cost of materials and attachment is expensive, There is a problem in that the packaging bag is bulky and difficult to handle because the packaging bag is stacked thereon, so that a part of the packaging bag is cut out to form an injection port. (See Patent Document 2 below).

However, in the case of a structure in which a part of the packaging bag is cut out to form an injection port, the support of the pouch tends to become unstable if there is no reliable supporting means for handling the pouch in a state in which the content of the liquid is accommodated. It is difficult to cut off some parts or to supply water or medicines. As a result, not only problems such as dropping or tilting of the packaging pouch and flowing of the contents, but also contact with the inside of the pouch, There was also a hygienic management problem.

In addition, the closing means such as the zipper seal which is provided in advance in the opening portion may not be engaged due to the internal pressure due to the water during storage or transportation, and the water may adhere to the engaging portion and may be insufficiently engaged with each other, For this reason, there has been developed an eyepiece part for separating the closing means from the receptacle before opening and peeling off at the time of opening (see patent applications 3 and 4 below).

Conventionally, such an easy-to-peel portion is formed by bonding film pieces constituting a packaging bag to each other by a peeling chamber. However, when the inner pressure is applied to the inside of the packaging bag by dropping or the like during storage or transportation, In some cases, it can not be completed.

(See Patent Applications 5 and 6 below), it is also possible to provide an inner pressure of the inside of the pack- age bag for the purpose of specifying the opening by peeling of the outer-layered portion or by reducing the inner pressure by rupture of the outer- It does not prevent the easy peeling part from peeling off due to the influence of the peeling.

In addition, a separate member such as a molding member is attached to the peripheral portion of the package bag as a main outlet member in order to facilitate the introduction of the contents. When the main outlet member is exposed to the outside of the packaging bag before opening, such as during transportation or storage, there is a fear of being exposed to the outside air or a dong, etc., and the outlet member is permeable to H ₂ O and O ₂ from the main outlet member. Oxidation or deterioration such as vitamin destruction may occur. As described above, there are some cases in which the main outlet member is inserted between the film pieces because of problems in hygiene management or quality control (refer to Patent Documents 7 and 8 below).

However, all of the main outlet members of the packaging bag described in the following Patent Literature are likely to come into contact with fingers or the like near the main outlet at the time of unsealing, and the main outlet member can be re-sealed after opening, There is a problem in handleability and contamination prevention property since it must be used out.

Also, the main outlet member is easy to move even when it is placed in the package bag, and is likely to be damaged by external impact or the like.

The filling of the contents is performed by forming a part of the peripheral portion of the package bag as an unexposed portion and then filling the unexposed portion with the filling material and filling the unexposed portion. 14 is a front view of a packaging bag, which is an example of the embodiment of the present invention, FIG. 15 is a sectional X-X sectional view of the packaging bag of FIG. 14, Fig. In the figures 14 to 16, the body portion of the packaging bag 53 is formed with the receiving portion 55 by making the peripheral portion 54 of the two film pieces 53a, 53a into the yarn seal portion (indicated by oblique lines in FIG. 14) by fusion or the like . The filling of the contents is performed by forming a part of the peripheral portion of the package bag as an unexposed portion and then filling the unexposed portion with the filling material and filling the unexposed portion. 20 is a front view of the main outlet member which is an example of the embodiment of the present invention, FIG. 21 is a sectional view seen from the frontal direction of the main outlet member of FIG. 20, 23 (a) is a front view of the cap portion after opening the main outlet member of FIG. 20, FIG. 23 (b) is a bottom view of the cap portion of FIG. 23 (a) Fig. 24 (a) is a front view of a pouring portion after opening the main outlet member of Fig. 20, and Fig. 24 (b) is a bottom view of the pouring portion of Fig. 24 (a).

In the peripheral portion 2 of the package bag 1, an injection portion 3 and a discharge portion 4 are provided. The injection part 3 is provided on the upper portion 2 a of the peripheral part 2 to widen both end part seal parts 2 b and 2 b of the upper side part 2 a so that the inner part of the package becomes a shape protruding upward from the unillustrated part and becomes an injection port after opening. The injection section 3 is provided with an easy opening section 6 which traverses from the seal section to the seal section on the opposite side from the unsiled section which serves as the injection port and holds the upper side of the easy release section 6 and the upper side section An opening portion formed by the unsiled portion is formed and the injection port 3a is opened and the injection port is opened. The easy opening section 6 is formed by a half cut by laser irradiation or the like. If the easy opening portion 6 is formed such that the trajectory of each of the two film pieces 1 a and 1 a forming the packaging bag 1 is formed, the position of the opening end cut according to the easy opening portion 6 is shifted It is easy to hold each film piece and to open the injection port. In the packing bag 1 of Fig. 1, a linear zipper 7 and an easy-to-peel portion 8 which are free to open and close are formed on a line connecting the holes 5 and 5 to be described later of the unarmed portion. The line-shaped zipper 7 is provided in order to facilitate hygiene control by closing the injection port after the injection operation. The line-shaped portion 8 is provided for enhancing the airtightness before opening the injection port. In practice, the upper portion of the film is cut off by the easy opening portion 6, The fill part 8 is peeled off and the injection port is completely opened.

The packing bag 1 has two holes 5, 5 passing through the film piece, with a portion to be the injection port 3a being interposed therebetween in the seal portions 2b, 2b at both ends of the upper end portion which is the peripheral portion near the injection portion 3. The holes 5 and 5 are suspending means capable of suspending the pouch. As shown in FIG. 3, when the bundle bag 1 is hanged by hanging a jig (indicated by reference numeral 20 in FIG. 3) on one side of the holes 5 and 5, (Indicated by arrows in Fig. 3) of the contents from the extruding part 4 becomes easy. It is also possible to easily supply water or medicine from the injection port 3a formed by opening the injection section 3 disposed at the upper side. In addition, the holes 5 and 5 may be the size of the fingers so that the fingers can be used to secure the handling of the package. Concretely, for example, when the injection section 3 is opened, one side of the holes 5 and 5 is covered with another finger (for example, an index finger) on the other side, And then opened with another hand by cutting at the easy opening portion as described above to form the inlet 3a as shown in Fig. Water or medicine can be replenished from the injection port 3a thus formed as indicated by arrows in Fig.

In the present invention, as described above, by providing two or more holes with a part serving as an injection port therebetween as a supporting means by the fingers of the packaging bag, it is possible to reliably support the vicinity of the injection port, It is possible to easily carry out the supply operation of moisture and the like, and there is a problem that the package bag is dropped or tilted to flow the contents, a problem that the injection port comes into contact with the inside of the package bag, The occurrence of a problem can be reduced. Further, since the hole serves also as a suspending means capable of suspending the packaging bag, it is possible to easily form the supporting means without adding a separate member or the like. Also, it is possible to use a finger as a means for hanging one hole while holding a finger in the other hole and stably performing the opening operation.

The packaging bag of the present invention has a structure in which a peripheral portion of the film is partially cut off and an opening portion is formed by the unexposed portion to form an injection port, instead of mounting the injection portion to a peripheral portion such as a molded article. When the injection port is made to be a large diameter, the member on the back side of the molded article becomes large, and it becomes inconvenient because the volume becomes large when it is piled up and stored before or after the receiving water is accommodated. It is possible to manufacture a packaging bag which is easy to store and transport and which has a large-diameter injection port at low cost. Since the structure of the injection section as described above is liable to become unstable at the time of unsealing because the film piece is pulled by hand or scissors or the like compared to the case of using the molded article and the packaging bag is dropped or tilted There is a problem such as a leakage of water and a problem of contamination of the injection port due to the contact with the inside of the packaging bag. However, in the present invention, two or more holes are formed with a portion serving as an injection port therebetween.

The hole may have at least two holes with a portion serving as an injection port therebetween. However, for example, three or more holes may be provided in consideration of the size of the packing bag and the size of the hand. Also, the arrangement of the holes is not particularly limited as long as the hole can be stably supported by a finger with a portion serving as an injection port therebetween.

The shape of the hole is not particularly limited as long as it is possible to hold a finger when handling the packing bag, and it is possible to use a circular or circular hole like the hole 5 in the packing bag of Fig. 1 or a slit shape as shown in Fig. 5 Quot; 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 case of a slit shape since it is easy to fasten the finger, Do. Further, as shown in Fig. 6, the film piece on the periphery of the hole may not be stuck. In FIG. 6, the unexposed portion (unexposed portion) is indicated by reference numeral 16. Since the non-threaded portion is not rigid and flexible compared to the threaded portion, the end portion of the film is bent even when the finger is stuck, so that the thread edge is hard to directly touch the finger. The width of the unsealed part is set appropriately according to the size of the pouch and the hole. 7 (a) to 7 (c), the remaining peripheral portions are removed from the perforated lines (FIGS. 7 (a) to 7 (c) (Shown as 13 '' in FIG. 7 (d)), as shown in FIG. 7 (d) The perforated line or the half cut may be broken at the time of use so that a part of the film piece (indicated by 14 in FIG. 7 (e)) is connected to the package bag main body. A film piece connected to the packaging bag body is inserted, so that it is difficult for the finger to touch the end portion of the film piece, so that the finger does not become sore. It is more preferable that the position where the part of the film piece is connected to the package bag body is supported by the inserted part of the film piece. Further, a part of the hole may be a through hole so as to easily break the perforated line or the half cut.

Furthermore, the above-mentioned hole may be a shape in which the upper portion of the hole is convex downward when used as a supporting means by a finger. In the case of the above-described shape, the upper portion of the convex shape is bent when the finger is supported, so that the film is supported by the folded portion of the film, so that it is difficult for the finger to touch the end portion of the film piece. And a non-threaded portion in which the film piece on the upper side of the hole is not broken may be formed. If the hole side film portion is not stuck on the hole side portion, the unexposed portion is not strong and flexible as compared with the seal portion, so that the upper portion of the convex shape is more likely to be bent.

Figs. 12 and 13 show an embodiment in which the above-mentioned hole has a shape in which the upper portion is convex downward when it is used as a support means by a finger. FIG. 12 is a front view of a packaging bag, which is another example of the embodiment of the present invention, and FIG. 13 is an enlarged view of a hole in the packaging bag of FIG. Note that the shape of the hole 5 in the packaging bag shown in Fig. 1 is different from that shown in Fig. 12, and the parts having the structure overlapping the packaging bag in Fig. 1 are denoted by the same reference numerals. As shown in FIG. 13, the hole 50 in the packing bag shown in FIG. 12 has a semi-circular shape in which the lower portion 50a is semi-circular in use and the upper portion 50b is convex downward 51). In addition, the film piece on the upper side of the hole 50 serves as the unsiled portion 52. In the case of the above-described configuration, the shape of the upper portion is convex downward when used as a support means by the fingers of the hole, but the shape of the hole other than the upper portion is not particularly limited, and circular, circular, An elliptical shape, a rectangular shape, or the like, or a combination thereof. The shape of the convex portion of the upper side portion and the range of the unsealed portion are also not particularly limited within a range that does not hinder the effect that the end portion of the film piece is less likely to touch the fingers.

In the present invention, in order to increase the stability and facilitate the handling operation when the packing bag is supported by the fingers, it is preferable that the rigidity on the line connecting the holes, which sandwich the portion to be the injection port, desirable. With this configuration, not only is the film piece of the packaging pouch main body hardly crumpled at the time of opening, but also the opening operation becomes easy. In addition, after the opening, the injection port is opened by simply pressing the injection port lightly from the left and right with the finger inserted into the hole serving as the support means. . After the injection operation, just by loosening the force of the finger, the injection port returns to its original state, and the sanitary control is also preferable.

As described above, as a method of increasing the stiffness on the line connecting the holes to be the injection port with each other, the line-shaped zipper portion is formed on the line connecting the holes that sandwich the portion to be the injection port Method. The zippered portion has an advantage that the injection port can be closed after replenishing from the injection port, thereby facilitating hygiene control, but at the same time, the stiffness of the line can be increased. In addition, a member having higher rigidity than the film piece constituting the packaging bag may be attached in a strip shape on the above-mentioned line.

The packaging bag of the present invention has a peripheral portion separately from the injection portion in the peripheral portion 2. In the main release, the bag is suspended by a suspending means. Therefore, it is necessary to arrange the dischargeable portion at every month, and it is preferable that the discharge portion is disposed at a position opposite to the suspending means, that is, at a position facing the injection port. In Fig. 1, the lower end portion of the packaging bag main body is cut out inwardly, and the extending portion 4 is provided on one side of the cut portion. The jig 4 is hooked on one side of the hole 5 of the suspending means which also serves as a supporting means, and the package bag 1 is suspended in a substantially vertical downward direction on the hanging side of the package bag 1, The supply from the injection port 3a formed by opening is facilitated. In the packaging bag of the present invention, as described above, it is preferable that at least one of the holes is arranged so that the extruded portion is almost vertically downward when hanging as a means for hanging the hole.

In the packaging bag 1 of Fig. 1, the extrusion portion 4 is formed by attaching the base portion of the molded main outlet member 4a to the packaging bag main body by thermal bonding or the like so that the tips of the molded main outlet member 4a protrude from the packaging bag main body. The leading end portion of the main outlet member 4a is sealed by a cap or the like until it is opened, though not shown. In the main release, the cap is removed, the opening is opened, the main outlet is opened, and a tube or the like is connected to the main outlet to discharge the water to the outside.

In the present invention, the configuration of the extruded portion is not limited to the above. In addition, a pipe is sandwiched between the film pieces constituting the packaging bag main body to cut out a part of the film, thereby exposing the pipe and connecting a tube or the like to the pipe- And a configuration in which the water content is discharged to the outside. The constituent material, size and installation method of the main outlet member are not particularly limited as long as the desired sealing performance can be achieved without affecting the contents.
