Description

The present invention relates to a refillable packaging pouch with a spout of a standing pouch type having a spout . More specifically, when refilling into another bottle container, the fluid content can be discharged without causing pulsation, and even a paste-like fluid content with high viscosity can be smoothly fluidized. The present invention relates to a refillable packaging pouch with a spout that can discharge sewage .

  Conventionally, single-layer or multi-layer synthetic resin with a sealant layer on the inner surface for packaging for storing, storing and transporting toiletries such as liquid detergents, shampoos, rinses, body shampoos, household products and processed foods Flexible packaging bags and packaging containers (hereinafter also referred to as packaging containers) in which the peripheral edge of the film is heat-sealed are used.

  In recent years, compared to plastic bottle containers, the weight of synthetic resin can be reduced, and it can be crushed during disposal after use to reduce the amount of waste or reduce the volume of waste. Packaging containers composed of these synthetic resin films are increasingly used as countermeasures against environmental problems. As a refill packaging container for refilling fluid contents into a plastic bottle container equipped with a hand pump, a resin film at the bottom folded in two and two resin films on the front and back as the body A standing pouch that is assembled as a self-supporting packaging container by heat-sealing the outer peripheral end is representative. Generally, it is sometimes called a refill pouch.

  Such a packaging container for refilling is provided with a spout in order to improve usability during refilling. When opening this spout, a notch (notch for starting cutting) is formed in the spout so that it can be opened easily by hand without using tools such as scissors. Has become commonplace. Further, when opening from the notch as a starting point, a concave opening guide line that guides the opening may be formed so that the opening is easier.

By the way, although the packing container for refilling conventionally proposed is provided with a spout, it has a spout with a narrowed tip and a nozzle shape. And restricting abrupt outflow and determining the outflow direction of the fluid content (for example, see Patent Documents 1 and 2). In this case, since the refill pouch is composed of a thin plastic film, the container shape is not rigid, and in the space occupied by the fluid content that has flowed out of the refill pouch, It was difficult to supply outside air through the spout and replace it with outside air.
For this reason, the surface of the pouch for refilling was crushed by hand, and it squeezed out by making the opposing distance of two resin films approach, and had to flow out the fluid content. However, if two films are brought into close contact with each other at the spout, there is a problem that the spout is blocked and the fluid content cannot be discharged smoothly.

  In order to eliminate clogging of the spout and smooth discharge of the fluid content, the spout is prevented from clogging by being inflated by molding by embossing in the part of the spout (for example, Patent Documents 3 and 4), and a method of preventing the spout from being blocked by inserting a tube expanding tool into the spout portion (see, for example, Patent Document 5) have been proposed.

JP-A-9-183442 Japanese Patent Laid-Open No. 10-203567 Japanese Patent Laid-Open No. 11-11498 JP 2002-154559 A JP 2000-190996 A

However, embossing the resin film at the spout part to inflate it, or inserting a ring into the spout part reduces the clogging of the spout, but the flowable content of the spout is reduced. In parallel with the discharge, it is not successful to introduce the outside air into the container and discharge the flowable content by the weight of the flowable content. For this reason, in the case of fluid contents with low viscosity, the discharge from the spout is performed relatively smoothly, but the discharge of the fluid content and introduction of the outside air into the container through one spout Are alternately performed, and there is a problem that pulsation occurs in the discharge of the fluid content.
In addition, when the fluid content is discharged from the sealed packaging container, if the outside air is not replenished to the gap generated by the discharge of the fluid content, the fluid content is discharged, Negative pressure is generated. As a result, the resin films on the front and back constituting the packaging container are in close contact with each other, and it is not possible to avoid the occurrence of frictional resistance when discharging the fluid contents from the packaging container, and the viscosity is high from the spout. In order to discharge the paste-like fluid contents, it is necessary to squeeze and squeeze the resin film on the trunk part by hand, which requires considerable labor, and there is a problem that elderly people feel burdened.

Especially in pasty fluid contents with high viscosity, such as shampoos and conditioners, it is difficult to refill the fluid contents into other containers. Further improvements have been required for refillable packaging containers filled with. However, these problems could not be solved simply by means of preventing the spout from being blocked.
For this reason, when fluid content such as liquid, paste, and gel is refilled into another container, the fluid content can be discharged without causing pulsation and the fluid content of the paste is high in viscosity. There has been a demand for a packaging container with a spout that can smoothly discharge fluid contents even if it is a product.

The present invention has been made in view of the above circumstances, and when refilling into another bottle container, the flowable content can be discharged without causing pulsation, and the paste-like flowable content has a high viscosity. Even so, an object of the present invention is to provide a refillable packaging pouch with a spout that can smoothly discharge fluid contents.

  In order to solve the above problems, the present invention provides an upper surface (liquid surface) of a fluid content in a state in which the packaging container is inverted before the fluid content filled in the packaging container is transferred to another container. By opening using an opening means provided at a position higher than the position, the inside and outside of the packaging container are communicated with each other by a vent hole different from the spout, and atmospheric pressure is applied to the upper part of the fluid content Therefore, the fluid content is discharged without causing pulsation due to the self-weight of the fluid content, and the fluid content can be poured smoothly even if it is a paste-like fluid content with high viscosity. The technical idea is to discharge from the exit.

To solve the above problems, the present invention is exposed when transferring the fluid content in the bottle container, the spout is inserted into the mouth of the bottle, provided on one of the corners of the top, top of the other In a refillable packaging pouch with a spout of a standing pouch type in which a filling port is formed at a location excluding the spout portion, in the vicinity of the lower corner facing the spout, A vent hole for introducing air into the refill packaging pouch with a spout is used when refilling the fluid content of the refill packaging pouch with a spout into another bottle container. Provided is a refillable packaging pouch with a spout, characterized in that an opening means is provided, and a suspension hole is provided at the peripheral edge of the lower corner on the diagonal line with the position of the spout. To do.

  Further, the opening means may be an opening guide line made up of a notch that penetrates two films and induces tearing, and a half-cut groove formed in a heat seal portion at a side peripheral edge or bottom bottom. preferable.

Further, in a direction tear by the notches is derived, it is preferred that each two of the unsealing guide line consisting of half-cut grooves in two films are overlapped is provided.

Further, in the direction in which the notch is guided by the notch, each of the two unsealing guide lines made of half cut grooves on the two overlapped films and each of the half cut grooves made on one non-overlapping film It is preferable that two opening guide lines are provided.

  Further, the flow path of the vent hole for introducing the atmosphere is partitioned so as to face the outside of the peripheral edge by a seal portion formed by sealing two films, and the notch is connected to the flow path of the vent hole. The two films that are provided extending from the orthogonal direction toward the flow path of the vent hole, and each of the two films that surround the flow path of the vent hole are each formed of a half cut groove formed by a laser. It is preferable that the opening guide line is provided away from the notch and along the extending direction of the end portion of the notch.

  Moreover, it is preferable that a tube expansion tool for preventing blockage is inserted or embossed in the flow path of the vent hole.

  The spout is preferably a flow path formed by heat sealing or a spout made of a molded resin.

According to the present invention, note in the vicinity of the lower corner portion of the outlet facing, note by separately providing vents and outlet for communicating the inside and the outside of the Note packaging pouch outlet with refill, vent An opening means for opening is provided.

To discharge the flowable contents, pull the opening knob 6 of the spout 5 by hand, tear it along the opening guide line 7 from the notch 8a, open the spout 5, and expose the spout 5 Is possible. 1 and / or B, as shown in detail in FIGS. 2 and 3, respectively, are provided with vents for introducing air when refilling the fluid contents of the packaging container. An opening means is provided. In addition, in FIG.1 and FIG.4, the packaging container which provided the opening means of FIG.2 (b) in A part is shown as an example.

In FIG. 1, the portion A of the packaging container 10 with a spout according to the present invention, which is in the vicinity of the lower corner portion facing the spout 5 and is the heat seal portion 1 of the side surface peripheral portion, is shown in FIG. 2), an opening means for opening a vent hole for introducing air as shown in FIGS. 2B and 2C is provided. In FIG. 2A, a plurality of notches 14a are provided in a part of the heat seal portion 1 at the peripheral edge of the side surface, and the heat seal portion around the notches 14a is manually pulled to guide opening from the notches 14a. Cut along the line 11 to a position reaching the inside of the packaging container with spout, open the vent (not shown), the inside and outside of the packaging container communicate with each other, and the upper part of the fluid contents When the atmospheric pressure is applied, the fluid content can be smoothly discharged by the action of the weight of the fluid content.
In FIG. 2B, a vent hole 17 is provided in a part of the heat seal portion 1 at the peripheral edge of the side surface, and the opening guide line is drawn from the notch 15a or 15b by pulling the opening knob 18 by hand. By tearing along 12 and opening the vent hole 17, the vent hole 17 can be exposed to the atmosphere, and the inside and outside of the packaging container with a spout can be communicated. In order to ensure the flow path of the vent hole 17, it is preferable that a tube expansion tool for preventing the blockage is inserted or embossed in the flow path of the vent hole 17.
In FIG. 2 (c), a part of the heat seal part 1 at the peripheral edge of the side surface is provided with an opening knob 19 and a notch 16a, and the opening knob 19 is pulled by hand to open from the notch 16a. It cuts along the guide line 13, opens a vent hole (illustration is omitted), and allows the inside and outside of the packaging container to communicate with each other.

When the fluid content filled in the packaging container with a spout of the present invention is refilled into, for example, a plastic bottle container, the spout 5 in which the spout 5 has been exposed in advance as shown in FIG. In the state where the spout 5 of the attached packaging container is inserted into the mouth of the plastic bottle container 20 and the packaging container 10 with the spout is inverted, for example, along the opening guide line 11 from the notch 14a shown in FIG.

Alternatively, the opening knob 19 shown in FIG. 2 (c) is pulled by hand, and is cut from the notch 16a along the opening guide line 13 to open the vent hole.
Moreover, it is possible to make the refilling operation into another container smooth by suspending the packaging container with a spout of the present invention by utilizing the hole 4 for suspending. In particular, in the state where the packaging container 10 with the spout is inverted, there is no need to perform the opening operation with one hand while supporting the weight of the fluid contents with one hand, and the opening means can be opened with both hands. Even elderly people who have weakened their grip can easily open. A spout 5 is provided at the upper corner on the diagonal and the position of the hole 4 for suspending, and an opening means for opening the vent hole is disposed in the outer peripheral heat seal part in the vicinity of the hole 4 for suspending. Therefore, even when the vent hole of the opening means is opened with the spout 5 inserted into the mouth of the bottle container 20, the upper surface 31 (interface contacting the atmosphere) of the fluid content 30 is below the opening means. Fluid content does not leak from the means. Further, since the vent hole is opened obliquely above the packaging container 10 with the spout with the spout hole 4 facing almost directly below with the suspension hole 4 as a fulcrum, the fluid content 30 is poured out when the vent is opened. Occasionally, the packaging container 10 with a spout is prevented from swinging or the spout 5 is removed from the mouth of the bottle container 20, thereby improving workability.
Moreover, the packaging container with a spout according to the present invention can be left in an inverted state if it is suspended by using a suspension hole, and further inside the packaging container with a spout by using the ventilation means according to the present invention. If air is introduced, even a paste-like fluid content with a high viscosity can be almost completely discharged from the inside of a packaging container with a spout, so that resources can be effectively used and economical.

Further, in FIG. 1, in the packaging container 10 with a spout according to the present invention, in the vicinity of the lower corner portion facing the spout 5 and in the B portion of the heat seal portion 2 at the bottom, FIG. As shown in FIGS. 3B and 3C, opening means for opening a vent hole for introducing the atmosphere is provided. In FIG. 3A, a plurality of notches 24a are provided in a part of the heat seal portion 2 at the bottom, and the heat seal portion around the notches 24a is pulled by hand to open the guide guide line 21 from the notches 24a. To the position where it reaches the inside of the packaging container with a spout, opens the vent (not shown), the inside and outside of the packaging container communicate with each other, and atmospheric pressure is applied to the top of the fluid contents. By adding the fluid content, the fluid content can be smoothly discharged by the action of the weight of the fluid content.
Further, in FIG. 3B, a vent hole 27 is provided in a part of the heat seal portion 2 at the bottom, and the opening knob 28 is pulled by hand so that the notch 25a or 25b leads to the opening guide line 22. By tearing along and opening the vent hole 27, the vent hole 27 can be exposed to the atmosphere, and the inside and outside of the packaging container with a spout can be communicated.
In FIG. 3C, an opening knob 29 and a notch 26a are provided in a part of the heat seal portion 2 at the bottom, and the opening guide line is drawn from the notch 26a by pulling the opening knob 29 by hand. It cut | disconnects along 23, an air vent (illustration omitted) can be opened, and it becomes possible to make the inside and outside of a packaging container communicate.

  When refilling the fluid contents filled in the packaging container 10 with the spout of the present invention into, for example, a plastic bottle container, as shown in FIG. 4, the spout 5 is exposed in advance. The outlet 5 of the packaging container with outlet is inserted into the mouth of the plastic bottle container 20 and the packaging container with outlet is inverted, for example, along the opening guide line 21 from the notch 24a shown in FIG. Open the vent hole by cutting. Alternatively, the opening knob 28 of FIG. 3B is pulled by hand, and the vent hole 27 is opened by tearing along the opening guide line 22 from the notch 25a or 25b. Alternatively, the opening knob 29 shown in FIG. 3C is pulled by hand, and the vent hole is opened by tearing along the opening guide line 23 from the notch 26a. Even when the opening means is provided at the lower end bottom B, as in the case where the opening means described above is provided at the side peripheral edge A, the hole 4 for hanging the packaging container with spout is utilized. Can be hung.

Spout opening knobs 18, 19, 28, 29 formed with such notches (15a, 15b, 16a, 25a, 25b, 26a) and opening guide lines (12, 13, 22, 23). If you try to open the vent hole by pulling it by hand, the force concentrates on the notch, so you can start opening easily. In addition, since the opening guide line is formed continuously with the notch, the tearing can be stably advanced along the opening guide line, and the position to be opened can be prevented from being shifted from the planned position.
The shape of the notch may be a U-shaped or V-shaped cutout or a simple cut in addition to a linear cutout, and the shape is not limited. Furthermore, in order to prevent unintentional cracks starting from the notch due to impact or the like, the vicinity of the tip on the notch side of the opening guide line is different from the direction of the force applied to the notch, for example, a semicircle. In addition to the shape, it may be formed in a substantially semicircular shape, a V shape, a U shape, or the like. Further, even in the case of a semicircular shape, the size can be set as appropriate. As another method for preventing unintentional cracks starting from the notch due to impact or the like, the opening guide line may be separated from the notch and provided along the extending direction of the end of the notch. Good. In this case, the distance between the tip of the opening guide line on the notch side and the tip of the notch on the opening guide line side is preferably, for example, 0.3 to 0.8 mm.
Two opening guide lines are provided in the direction in which tearing is induced by the notch on the two films overlapped in the heat seal portions 1 and 2 and the unsealed portion 9 inside thereof, and the two opening guides are provided. It is preferable to guide the tear between the lines from both sides. In this case, even if each of the two opening guide lines is separated from the notch, it is provided along the extending direction of the end portion of the notch so that the tearing protrudes from between the two opening guide lines. It becomes difficult. Further, if tearing is easy, an opening guide line may be provided only on one of the two films. Here, the two films stacked in the heat seal part are two films on the front and back of the body part when the opening means is provided on the side surface peripheral part A, and the opening means is the bottom bottom part. When it is provided in B, it is one of the two films on the front and back of the body, and one synthetic resin film on the bottom folded in two. Further, when one of the two stacked films is extended so as not to overlap, an opening guide line may be provided continuously to the extension.

The notch and the opening guide line can be formed by the following method, for example.
First, a notch is formed by irradiating a laser such as a carbon dioxide laser to a predetermined location in the heat seal portions 1 and 2 by scanning a plurality of times from both the front and back surfaces. Here, the film constituting the opening means for opening the air holes 17 and 27 is made of a PET layer or the like in which the outer layer easily absorbs the laser. Therefore, the portion of the outer layer irradiated with the laser generates heat and melts, Evaporate. Then, due to the heat generated at this time, the inner layer made of an LLDPE layer that hardly absorbs the laser is also melted and evaporated to form a notch penetrating the film.

Next, after forming the notch, the laser is further scanned and irradiated to form a concave opening guide line continuous with the notch. At this time, the unsealing guide line needs to be formed with a sufficient strength and a depth that can be easily torn by hand. Make sure that it is not too deep or impossible to tear by hand. Usually, the laser is irradiated to such an extent that the outer layer evaporates and the inner layer is exposed to form the unsealing guide lines 11 to 13 and 21 to 23 formed of half-cut grooves.
The unsealing guide lines 11 to 13 and 21 to 23 are formed over a length of at least about 2 to 15 mm toward the inside of the container after reaching the unsealed portion 9 in which the fluid contents are accommodated. Therefore, the vent hole can be formed by tearing from the notch to the position where it can be easily torn by hand. Among these, the unsealing guide lines 12 and 22 shown in FIG. 2 (b) and FIG. 3 (b) pass through the flow paths of the vent holes 17 and 27 in a shape in which the unsealed portion 9 protrudes toward the heat seal portions 1 and 2. Since it crosses and the both sides of a flow path are divided by the heat seal parts 1 and 2 after opening, it is easy to handle. Further, the opening guide lines 11, 13, 21, and 23 shown in FIGS. 2 (a) and 2 (c) and FIGS. 3 (a) and 3 (c) are located on the unsealed portion 9, and thus have fluidity. By extending the tear while taking care not to leak the contents, the vent hole can be enlarged in the extending direction as necessary.
Since the unsealing guide line formed by irradiating a laser is extremely thin and difficult to visually confirm, printing the dotted line, broken line, etc. along the actual unsealing guide line so that the position of the unsealing guide line can be visually confirmed Is preferably displayed.

Here, the laser is not particularly limited as long as it can form a notch and an opening guide line. A gas laser other than a carbon dioxide laser, a solid laser such as a YAG laser, a semiconductor laser, or the like can be used depending on the material of the resin sheet. It can be used as appropriate.
The output of the laser used is preferably in the range of 3 to 100W. If the output is less than 3 W, it may take a long time to form the notch, and if it exceeds 100 W, the laser device tends to be expensive. In addition, in order to form the notch and the opening guide line, the number of times the laser is scanned with respect to the portion can be appropriately set. For example, the laser output is in the above range, and the notch and the opening guide line as shown in the illustrated example. In order to form the notch, the laser is scanned 3 to 10 times in a reciprocating manner, and the laser is scanned 1 to 2 times in a reciprocating manner in order to form the opening guide line.

  As described above, when a laminated sheet made of an LLDPE layer or the like whose inner layer is difficult to absorb laser and the outer layer is easily formed of PET or the like as the outer layer is used as the packaging container 10, the notch and opening guide are provided by the laser irradiation described above. Lines can be manufactured continuously, easily and accurately. Further, if at least a portion where the notch and the opening guide line are formed of such a laminated sheet in the packaging container 10, these can be formed by the laser irradiation described above. However, the material of the packaging container 10 is not particularly limited to these, and can be appropriately selected according to the properties of the fluid content to be filled. For example, you may form the packaging container 10 only from the material which cannot absorb a laser easily. In that case, the opening guide line can be formed by mechanically forming a notch using a blade mold and further forming a concave shape by mechanically scratching the surface with a cutter or the like.

  In the packaging container with a spout of the present invention, the synthetic resin film on the front and back of the body part and the synthetic resin film folded in two at the bottom part are conventionally used materials such as biaxially stretched polypropylene film, Various films such as a biaxially stretched polyamide film, a biaxially stretched polyester film, and an ethylene-vinyl alcohol copolymer film are used as a base material. Low-density polyethylene, linear low-density polyethylene, and ethylene-acetic acid are used as the base film. A composite film in which an olefin-based thermal adhesive resin such as a vinyl copolymer or polypropylene is laminated as a sealant layer is used. In this case, a plurality of the above-described various films may be laminated on the base material in order to enhance the protection of the fluid content, and further a metal thin film layer such as an aluminum foil may be used. Further, the structure of the packaging container with spout of the present invention is not particularly limited, but a standing pouch-type packaging container that can stand by itself after filling with the fluid content is preferable.

  As an example of the resin sheet used in the packaging container with a spout according to the present invention, the outer layer is, for example, a biaxially stretched polyethylene terephthalate (PET) layer having a thickness of 12 to 25 μm or a two layer having a thickness of 15 to 25 μm. It is an axially stretched polyamide resin layer, and the inner layer is a laminated sheet made of, for example, a linear low density polyethylene (LLDPE) layer having a thickness of 100 to 150 μm, and includes a wet lamination method, a dry lamination method, and a solvent-free dry layer. Manufactured by lamination method, extrusion lamination method, coextrusion lamination method and the like.
