Description

  The present invention relates to a pouch container including a pouch formed of a flexible sheet and a spout member attached to the pouch, a pouch package body in which contents are packed and packaged in the pouch container, and a spout member.

  For example, a pouch container for filling and packaging liquid, powder, and granular contents such as liquid detergent and powder detergent is equipped with a spout member for pouring out the contents. As the outlet member, one having a measuring function has been proposed so that a predetermined amount of contents can be measured and poured out (see Patent Document 1).

  As a spout member with a measuring function, for example, there is a member as shown in FIG. As shown in the figure, the spout member 50 is fitted into the pouch P at one end side and has a cylindrical mouth body 51 with both ends open, and is slidably fitted into the mouth body 51. And a cylindrical measuring container 52 whose both ends are closed. The peripheral surface of the measuring container 52 has a content inlet 52a at one end and a content spout 52b at the other end. Are formed respectively.

  When the weighing container 52 is slid to one end side of the mouth body 51 and the one end side of the weighing container 52 is protruded from the mouth body 51 into the pouch P, the introduction port 52a is opened and the other of the weighing container 52 is opened. The end side enters the mouth body 51 and the spout 52b is closed. When the weighing container 52 is slid in the reverse direction and the other end side is projected from the other end side of the mouth body 51, In addition, the spout 52b is opened, and one end side of the measuring container 52 protruding into the pouch P enters the mouth portion main body 51 so that the introduction port 52a is closed.

  Accordingly, as shown in FIG. 16 (a), one end side of the mouth part body 51 is placed in a state where the one end side of the measuring container 52 is protruded from the mouth part body 51 into the pouch P so that the introduction port 52a is opened. Thus, when the pouch container is turned upside down, the contents are introduced into the measuring container 52 from the introduction port 52a. After weighing a certain amount of contents in the measuring container 52, the inlet 52a is blocked by causing the other end of the measuring container 52 to protrude from the other end of the mouth part body 51 as shown in FIG. At the same time, when the spout 52b is opened, a fixed amount of the measured content is poured out from the spout 52b.

  Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 shows a pouch package 1 in which liquid, powder, and granular contents such as liquid detergent and powder detergent are filled and packaged in a pouch container 2. As shown in the figure, the pouch container 2 is formed of a flexible sheet having a thickness of about 80 to 200 μm, and can be folded into a flat state, and a thermal bonding attached to the pouch 10 as a spout member. And a spout 20 made of a conductive resin.

  The flexible sheet forming the pouch 10 is usually composed of a single-layer or multi-layer resin film, and a multi-layer sheet having a base film layer and a sealant layer imparting heat sealability is preferable. When a high gas barrier property is required, it is preferable to provide a gas barrier layer between the base film layer and the sealant layer.

  The film constituting the base film layer is composed of polyester such as polyethylene terephthalate, polyolefin such as polyethylene and polypropylene, polyamide such as nylon-6 and nylon-66, and ethylene-vinyl alcohol copolymer (EVOH). One or two or more layers of stretched or unstretched films can be exemplified.

  As the film constituting the sealant layer, low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP) , Biaxially stretched nylon (ON), ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. A stretched or unstretched film having one layer or two or more layers can be exemplified.

  As the gas barrier layer, a metal thin film such as aluminum, a resin film such as vinylidene chloride (PVDC), an ethylene-vinyl alcohol copolymer (EVOH), or an arbitrary synthetic resin film (for example, a base film layer) And a film obtained by evaporating (or sputtering) an inorganic oxide such as aluminum, aluminum oxide, or silica.

  As shown in FIGS. 1 and 2, the pouch 10 is folded inward from the bottom between the exterior sheets 11 and 12 and the exterior sheets 11 and 12 forming the front and back portions to form a bottom gusset portion. The gusset sheet 13 is made up of. The exterior sheets 11 and 12 have a substantially pentagonal shape having an inclined edge at one of the upper corner portions, and the inclined edge becomes the spout mounting edge portion 10A. The peripheral edge of the folded gusset sheet 13 is heat-sealed to the lower periphery of the exterior sheets 11 and 12, and both side edges of the exterior sheets 11 and 12 that are not heat-sealed to the gusset sheet 13 are heat-sealed to each other. It is formed in a bag shape. Further, notches 13a are formed on both side edges of the gusset sheet 13 so as to coincide with each other in a folded state. Is partially heat sealed. 1 and 2 indicate the heat seal portion of the pouch 10.

  In the pouch container 2, the spout mounting edge 10A, which is an inclined edge, is heat-sealed with the spout 20 sandwiched therebetween, but the upper edge adjacent to the spout mounting edge 10A is filled with the contents. The filling port forming edge portion 10B serving as the filling port is in an unsealed state. The filling port forming edge portion 10B is closed by heat sealing after filling the contents.

  The spout 20 is made of a molded product of a heat-adhesive resin such as an olefin resin (for example, polyethylene or polypropylene), and is sandwiched between the spout mounting edges 10A of the exterior sheets 11 and 12, as shown in FIG. A flat boat-shaped mounting portion 21 that is heat-sealed to the exterior sheets 11 and 12 in a state, a mouth portion 22 that is connected to the mounting portion 21 so as to protrude outside the pouch 10, and a resin in the mouth portion 22 A cap 23 is provided continuously through a hinge 24, and a cylindrical measuring part 25 is provided continuously to the mounting part 21 so as to protrude into the pouch 10.

  As shown in the drawing, the measuring portion 25 has a distal end portion closed with a tapered shape, and a longitudinal surface of the mounting portion 21 having a flat boat shape is formed on the peripheral surface of the proximal end portion connected to the mounting portion 21. A substantially isosceles triangular inlet 25a for introducing contents is formed on one end side in the direction (upper end side of the pouch 10). As shown in FIG. 4, the pouch 10 is mounted so that the introduction port 25 a faces the upper edge of the pouch 10.

  The shape of the measuring unit 25 is not particularly limited. However, when the spout 20 is mounted on the pouch 10, the measuring unit 25 is provided so that the mounting unit 21 and the measuring unit 25 can be easily inserted into the open spout mounting edge 10A. It is desirable that the tip is tapered.

  As shown in FIGS. 3 (c) and 5, the introduction port 25a has a shape of a hole formed when a peripheral surface of the cylindrical body CB (metering portion 25) is partially cut away. It is desirable that the dimension SD of the excision part shown in FIG. The contents must be easily introduced into the weighing unit 25 from the introduction port 25a, and, as will be described later, because the excess of the content introduced into the weighing unit 25 is discharged by discharging from the introduction port 25a, This is because a certain degree of discharge is also necessary, and it is necessary to satisfy both requirements. In consideration of the introduction of the contents, it is desirable that the length SL in the axial direction of the introduction port 25a is not less than ¼ of the diameter D of the measuring unit 25.

  Further, in this pouch package, as described above, since the surplus portion of the content introduced into the measuring unit 25 is measured by being discharged from the introduction port 25a, the contents in the measuring unit 25 are provided from the outside of the pouch 10. It is desirable that the portion corresponding to the measuring portion 25 of the spout 20 and the measuring portion 25 of the pouch 10 is transparent or translucent so that the storage state of the spout 20 can be confirmed.

  In a state where the spout 20 is mounted on the spout mounting edge 10A in the pouch container 2, as shown in FIG. 2, the measuring section 25 of the spout 20 projects toward the filling port forming edge 10B. Therefore, the tip of the measuring part 25 of the spout 20 is the contents in the filling port forming edge 10B in order to smoothly and reliably insert the filling nozzle into the pouch 10 from the filling port forming edge 10B when filling the contents. When the length of the unsealed portion serving as a filling port for an object is L, the end portion on the spout mounting edge portion 10A side of the unsealed portion is separated from the other end portion by L / 3 in the same figure. It is desirable not to overhang the position indicated by the two-dot chain line. In this spout 20, when the mounting portion 21 is heat-sealed to the spout mounting edge portion 10A of the pouch 10, the measuring portion 25 is mounted so that the axis of the measuring portion 25 is orthogonal to the spout mounting edge portion 10A. 21. When the mounting portion 21 is heat-sealed to the inclined spout mounting edge 10A of the pouch 10 in order to make it difficult to project the measuring portion 25 toward the filling port forming edge 10B, The measuring part 25 may be connected to the mounting part 21 in a state where the axis of the measuring part 25 is inclined with respect to the axis of the mouth part 22 so that the axis of 25 is directed downward.

  For example, the operation of measuring and dispensing a certain amount of contents from the pouch package 1 configured as described above is performed as follows. First, as shown in FIG. 6, the pouch packaging body 1 is tilted so that the cap 23 portion of the spout 20 faces downward, and the measuring portion 25 of the spout 20 is buried in the contents, as shown in FIG. 7. While the pouch package 1 is returned to the original posture, the contents are introduced into the measuring unit 25 from the introduction port 25a.

  After the pouch package 1 is returned to the original posture, as shown in FIG. 8, the entire pouch package 1 is shaken up and down to vibrate and is introduced into the measuring unit 25 as shown in FIG. A certain amount of content is weighed by discharging the extra content introduced into the weighing unit 25 from the introduction port 25a so that the upper surface of the content is substantially horizontal at the lower end position of the introduction port 25a. Finally, as shown in FIG. 10, with the cap 23 removed and the mouth portion 22 opened, the entire pouch packaging 1 is tilted so that the contents are not introduced into the measuring portion 25 from the introduction port 25a. The contents stored in the weighing unit 25 are poured out from the mouth portion 22.

  As described above, the spout 20 employed in the pouch package 1 only needs to be connected to the measuring unit 25 having the introduction port 25a formed in a normal spout, so that a spout with a measuring function can be inexpensively provided. Can be manufactured.

  Moreover, in this pouch packaging body 1, as described above, it is possible to take out a certain amount of contents simply by tilting or shaking the entire pouch packaging body 1, so there is no need to perform troublesome lightweight operations. It is possible to easily perform the work until the contents are weighed and dispensed.

  Moreover, in this pouch package 1, since the measurement part 25 added to the normal spout is located in the pouch 10, the external shape may differ from the general pouch package which is not equipped with a measurement function. There is no deterioration in design.

  Further, the pouch packaging body 1 has a spout 20 mounted on a spout mounting edge portion 10 </ b> A which is an inclined edge formed obliquely downward from an upper end edge to a side end edge of the pouch 10, and is formed in the measuring unit 25. Since the introduced inlet 25a is opened so as to face the upper edge of the pouch 10, after weighing the contents, the same type that does not have a measuring function without being aware of the position of the inlet 25a, etc. The contents can be poured out in the same way as the pouch packaging of, and the handling is good.

  In the embodiment described above, only the mounting portion 21 portion of the spout 20 is heat-sealed to the spout mounting edge portion 10A of the pouch 10, but, for example, as shown in FIG. 11, from the inner edge of the spout mounting edge portion 10A. You may heat-seal over the both sides of the inlet 25a in the surrounding surface of the measurement part 25. FIG. In this way, since the introduction port 25a portion is partitioned, as shown in FIG. 10, when the content after weighing is poured out, it becomes difficult for the content to go around to the introduction port 25a side, and from the introduction port 25a. The effect that it is hard to introduce an extra content is acquired. In this case, in order to improve the heat sealability of the exterior sheets 11 and 12 with respect to the measuring unit 25, it is desirable to form the outer surface portion to be heat sealed in the measuring unit 25 flat. The cross-hatched part in FIG. 11 shows the heat seal part.

  In the above-described embodiment, the introduction port 25a formed in the measuring unit 25 has a triangular shape, but is not limited to this, and as shown in FIGS. 12 (a) and 12 (b). If the dimension SD is within ¼ of the diameter D, the shape may be a quadrangle. However, in the case of such a quadrangular shape, it is easy to spill out from the introduction port 25a when the contents weighed once are poured out, so that the peripheral portion of the introduction port 25a is attached as shown in FIG. It is desirable that the measuring portion 25 is inclined toward the axial center side toward the portion 21, that is, the introduction port 25a is triangular.

  Moreover, in order to make it easy to measure the contents, a scale for measurement may be attached to a part corresponding to the measurement part 25 of the spout 20 or the measurement part 25 of the pouch 10, as shown in FIG. In addition, by attaching a plurality of scales S1 and S2, it becomes possible to measure the contents of different capacities.

  The shape and size of the weighing unit 25A are not particularly limited. For example, as in the spout 20A shown in FIG. 5B, the contents in the weighing unit 25A are stored in order to increase the capacity of the weighing unit 25A. The cross-sectional shape of the portion to be formed may be elliptical. In that case, it is preferable to project it toward the introduction port 25a so that it can be smoothly poured out after weighing.

  In the above-described embodiment, the spout 20 in which the cap 23 is connected to the mouth portion 22 via the resin hinge 24 has been described. However, the present invention is not limited to this, and for example, as shown in FIG. Thus, you may use the spout 20B of the type which opens and closes the opening part 22B with the screw cap 23B.

Moreover, although the spout 20 in which the measuring unit 25 is integrally formed with the mounting unit 21 has been described, the spout 20 is not limited to this, for example, as in the spout 20C illustrated in FIG.
The weighing part 25 </ b> C formed independently may be fitted to the mounting part 21. When such a configuration is adopted, there is an advantage that the capacity to be weighed can be easily changed by using the weighing parts having different capacities as the mounting parts.

  Moreover, in embodiment mentioned above, although the pouch container 2 whose spout mounting edge part 10A of the pouch 10 with which the spout 20 was mounted | worn is an inclined edge is used, it is not limited to this, The upper edge of a pouch Needless to say, the present invention can also be applied to a pouch container having a spout attached thereto.

  In the above-described embodiment, the bottom gusset-type pouch container 2 is used. However, the present invention is not limited to this. For example, the present invention is applied to a side gusset-type or flat bag-type pouch container. be able to.

  INDUSTRIAL APPLICABILITY The present invention can be used for a pouch package with a content weighing function.
