Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an easy-to-open standing pouch with a pull tab devised so that the pull tab can be opened with a finger. The present invention also relates to a package filled with contents.
[0002]
[Prior art]
Liquid products such as detergents and shampoos are usually supplied to the market in containers such as bottles and bottles. However, the contents were consumed from the viewpoint of resource saving, disposal, and cost reduction. It is desirable to refill the contents of an optional standing pouch into a later empty container.
[0003]
As standing pouches for refilling for this purpose, those having various shapes and forms having a spout are known. A pouch is provided with a notch toward the spout, and when refilling it is torn from this notch and opened. The shape of the notch is various, such as an I notch (straight notch), a V notch (V-shaped notch), a U notch (U-shaped notch), and a notch with a U-shaped notch tip.
[0004]
In JP-A-2002-68212, a peripheral part is sealed by heat sealing means so that liquid can be sealed inside, and a part of the peripheral part is elongated from the inside and protrudes into a bag shape (discharge) A refill package made of a film, which is sealed with a sealing pattern that forms a channel) and can form a spout by tearing in a tearing path crossing the chamber. A refill package in which a slit that draws a curve from the proximal end of the atrioventricle along the side edge to the vicinity of the pouring spout formation portion or a cutout window that uses the curve as a part of the inner peripheral edge is shown in the part seal part. Has been.
[0005]
[Problems to be solved by the invention]
However, in the conventional refilling standing pouch, first the notch must be found and the upper and lower portions of the notch must be supported by the finger and then torn from the notch. The finger supported part is one of the contents of the pouch. Because it is near one corner, the pouch may fall or fall during the tearing operation and the contents may spill. Finding a small notch is not always easy for myopic people who are not wearing glasses or contact lenses, or who are becoming presbyopia due to aging. In addition, when tearing from the notch, depending on the tearing method, the tear line of at least one of the front and back films may come off the planned line in the middle and the opening may not be clean. It becomes difficult to pour smoothly into the container. And even if it can be opened smoothly, the liquid contents are stored in a full bag, so that there is a tendency that it is difficult to support the pouch that smolders by hand when refilling an empty container.
[0006]
The refill package disclosed in Japanese Patent Application Laid-Open No. 2002-68212 has various problems, but has the following problems to be solved.
1. When tearing, there is a risk that the tear line that crosses the atrioventricular chamber (the discharge passage) will be out of the planned line in at least one of the front and back films, and the opening may not be clean. This may interfere with the pouring operation.
2. In addition to the first slit leading to the atrioventricular chamber, a second slit for guiding the tear line passing through the atrioventricular chamber is provided. However, the second slit is provided in the narrow seal portion at the edge of the bag. There is a risk that the bag will be torn unexpectedly.
3. When tearing the finger grip or pick with one hand, you must either hold the entire pouch with the other hand or hold the bag edge seal with the other hand. However, since the edge seal is narrow and the liquid contents are stored in the full bag, there is a risk of spilling the contents when opened, and it is difficult to support the pouch that crawls with fingers when refilling an empty container. .
[0007]
Under such a background, the present invention applies the pull tab method, and by taking special measures to the structure and shape near the upper part of the pouch, the discharge path serving as a spout can be opened without failure, There is no risk of spilling the contents at the time of opening, and even if the tear line that opens the discharge path may shift, the tear line converges on the rear end side of the discharge path, so the pull tab part can be smoothly torn off. Further, it is an object of the present invention to provide an easy-opening standing pouch with a pull tab that can be easily refilled and filled into an empty container, and to provide a package filled with the contents.
[0008]

[0010]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail below.
[0011]
<Overhang area (2)>
In the easy-to-open standing pouch with pull tab of the present invention, the right side of the standing pouch (1) is located closer to either the left or right (considering that there are many right-handed people, Provide an overhanging area (2) that protrudes from the upper side of the bag (to the right of the upper side).
[0012]
The width and width of the overhang region (2) are designed in consideration of the area sufficient to arrange the discharge passage (3) and the pull tab (4), which will be described later. If it is about half the width, it will be balanced.
[0013]
<Discharge channel (3), pull tab (4)>
This overhang region (2) is basically a sealing surface where the front and back films are sealed, but in the region near the side of the bag of the overhang region (2), an unopened opening serving as a spout In order to form the discharge passage (3), the portion of the discharge passage (3) is an unopened unsealed portion.
[0014]
The remaining region, that is, the region at least on the upper side near the center of the overhang region (2) is the pull tab portion (4) for opening.
[0015]
<Pouch support knob (8)>
In the lower region of the pull tab portion (4), there is provided a bag support knob portion (8) for holding the bag with a finger when opened. Here, the lower region of the pull tab portion (4) may be the bag supporting knob portion (8) on the lower side near the center if the overhang region (2) has a margin. When there is no room in the overhang area (2), when forming the overhang area (2), a seal part is formed so as to enter the inner space of the bag (non-seal part surrounded by the peripheral seal part), and the seal May also be used as the bag support knob (8).
[0016]
<Easy tear line (6), notch (7)>
Between the pull tab portion (4) and the bag support knob portion (8), the lower end side of the edge of the pull tab portion (4) is set as a start end A and reaches the vicinity of the distal end side of the discharge passage (3). Provide an easy tear line (6). Furthermore, a notch (7) for opening the front end side of the discharge passage (3) is provided at the end B of the easy tear line (6).
[0017]
The easy tear line (6) from the start end A to the end point B is formed in a U shape so as to bypass the lower half side of the opening assisting means (5) described later .
[0018]
The easy tear line (6) is often a single perforation, but it may be a plurality of close perforations, or each perforation may be in the shape of an eight or a staggered pattern. . Moreover, it may be a line formed by scratching instead of the penetrating eyes.
[0019]
The notch (7) provided at the end B of the easy tear line (6) is optimally a V-notch formed by punching a triangular shape, but a notch with a V-shaped tip of the I-notch, U-notch and U-notch. And so on. In some cases, as long as it has such a notch shape, it may be a notch made of a row of fine scratches or micropores.
[0020]
<Devising the tip of the discharge channel (3)>
In the present invention, the notch (7) across the discharge passage (3) which is an unsealed portion is located between the bag side edge seal portion and the distal end side of the discharge passage (3) on the opposite shore in the horizontal direction. The boundary line is formed as a polygonal line with a shape of> as viewed from the notch (7) side.
[0021]
If the above boundary line is straight, the position where the film on the front and back is cut is shifted and reaches the bag side edge seal part (side seal part) and is caught by the bag side edge seal part, and the pull tab part (4) becomes the bag. It may become impossible to detach from the main body. However, when the boundary line is formed as a polygonal line with a shape of> when viewed from the notch (7) side as described above, the discharge from the start end A to the end B of the easy tear line (6) and further through the notch (7) If the tear line of at least one of the front and back films on the front side of the discharge channel (3) may be misaligned when the front side of the channel (3) is torn, Therefore, the entire pull tab portion (4) including the upper piece on the distal end side of the discharge passage (3) can be smoothly torn off.
[0022]
<Opening aid (5)>
In the present invention, the pull tab portion (4) of the overhang region (2) has a finger hook (5a) for passing a finger at the time of opening or a slip stopper (5b) for preventing a finger from slipping at the time of opening. An opening assisting means (5) is provided.
[0023]
The former finger hook (5a) is preferably a circular hole with a diameter close to that of the index finger or a through hole having a shape close thereto, but is formed by a notch such as an X mark or an * mark so that the finger can be inserted. Also good. For example, when providing a through hole and setting it as a finger hook (5a), in addition to the method of punching the seal part and providing the through hole, an unsealed part having a diameter larger than that of the through hole is provided, If a through hole is formed in the unsealed part by punching, a ring in which the front and back films are not sealed is formed on the inner periphery of the through hole, so that the load on the finger when the finger is put on the through hole is reduced. There is an advantage of reducing.
[0024]
Examples of the latter anti-slip (5b) include a small punch hole group and an embossed part by an uneven pressing die.
[0025]
<Opening aid (5 ') >

The bag side of the discharge channel (3) is rounded so as to be recessed inside including the bag side edge seal part (seal part on the bag side), and easy to insert or hook into the refill container port It is desirable to have a shape.
[0027]
<Filling port (9)>
The upper side opposite to the side where the bag overhang region (2) is provided is used as a filling port (9) for filling the contents by making it an unsealed portion. After filling the contents, the upper side is sealed to seal the whole.
[0028]
<Structure of other parts of pouch>
Since the pouch of the present invention is a standing pouch, the bottom of the pouch is configured to be able to stand according to a conventional method. The area around the pouch will be sealed.
[0029]
A non-seal portion may be partially provided at an appropriate position of the seal portion.
[0030]
<Packaging materials for pouches>
As a packaging material constituting the pouch, a material having a basic layer structure of “base material layer / sealant layer” is used, and the sealant layer is a layer on the inner surface side of the bag.
[0031]
Examples of substrate layers are biaxially stretched polypropylene film (OPP), biaxially stretched nylon film (ONy), biaxially stretched polyester film (PET), unstretched polypropylene film, unstretched nylon film, cellulosic film, synthetic paper Metal foil (aluminum foil, etc.). The base material layer may be composed of two or more layers. The base material layer is a gas barrier resin layer (ethylene-vinyl alcohol copolymer layer, acrylonitrile polymer layer having a high acrylonitrile content, polyvinylidene chloride resin layer, etc.), adhesive resin layer, anchor coating layer, vapor deposition layer (Metal vapor-deposited layer or ceramic vapor-deposited layer), printing layer (patterned or solid, formed on the inner or outer surface of the base material layer), topcoat layer (acrylic resin, epoxy resin, phenolic resin, urea-based) Resin, melamine resin, maleic acid resin, polyurethane resin, cellulose resin, etc.). The thickness of the base material layer is arbitrary as long as a predetermined strength can be obtained, but is often about 12 to 120 μm, for example.
[0032]
When using synthetic paper, the synthetic paper is preferably a synthetic paper having a layer structure of three or more layers of polypropylene. An example of such a polypropylene-based synthetic paper having three or more layers is a polypropylene film containing an inorganic filler, which is melt-formed and stretched in the longitudinal direction, and then the polypropylene containing the inorganic filler is applied to both sides of the longitudinally stretched film. This is a biaxially stretched film having a three-layer structure obtained by extrusion coating and then stretching in the transverse direction. Another example of a polypropylene-based synthetic paper having three or more layers is a polypropylene film containing an inorganic filler, which is co-extruded to obtain a three-layer film, and then first stretched in the longitudinal direction and then stretched in the transverse direction. Further, the biaxially stretched film thus obtained has a five-layer structure in which an undercoating layer and a top coating layer are provided on both sides and press smoothing treatment is further performed.
[0033]
On the other hand, as the sealant layer, low density polyethylene (LDPE), linear low density polyethylene (LLDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE), ethylene-vinyl acetate copolymer (EVA), ethylene Various heat-sealable properties including polyethylene resins such as saturated carboxylic acid ester copolymers, ethylene-unsaturated carboxylic acid copolymers, ionomers, ethylene-propylene copolymers; and polypropylene resins called CPPs. Examples of the resin layer. The sealant layer may be composed of two or more layers. The thickness of the sealant layer is not limited, but is often about 5 to 200 μm, particularly about 15 to 170 μm.
[0034]
The lamination between each layer is performed by a method such as a dry laminating method, a wet laminating method, a casting method, a sand laminating method, a coextrusion method, an extrusion coating method, and a printing method, except in the case of forming a vapor deposition layer.
[0035]
In the packaging material (front and back films) constituting the pouch, the orientation in the direction toward both sides is preferably set to be slightly larger than the orientation in the direction toward the vertical direction. This is because tearing can be performed smoothly.
[0036]
<Packaging body>
The package of the present invention is such that the above-described easy-opening standing pouch with a pull tab is filled with the contents.
[0037]
The contents are liquid, including hair care products such as shampoos and rinses, detergents, drinking water, liquid foods, liquid nutritional supplements, seasonings, edible oils, cosmetics, liquid fertilizers, agricultural chemicals, deodorants, and antibacterial agents. If it is a thing, it is arbitrary. Depending on the case, it may be in the form of powder or granule.
[0038]
This package is particularly useful for refilling empty containers, but may be one that is not refilled.
[0039]

The following examples further illustrate the invention. In each figure, the seal portion is indicated by dotted points.
[0040]
Example 1
FIG. 1 is a front view showing an example of an easily openable standing pouch with a pull tab according to the present invention.
FIG. 2 is an explanatory view showing a tearing state of the tip side portion of the discharge passage (3) in FIG.
[0041]
A biaxially stretched polyethylene terephthalate film (12 μm thick) is provided on one side of a 12 μm thick biaxially stretched nylon film (Ny) as an example of a substrate film by gravure printing. Dry laminate (DL) with an aluminum vapor deposition layer (VM) on the PET and Ny side on the PRT side, and a 130 μm thick linear low density polyethylene film (LLDPE) as a sealant layer on the PET VM side of the laminate Was extruded and laminated through a 15 μm thick melt extruded layer of low density polyethylene (LDPE). As a result, a laminated film having a layer structure of “Ny / Pt / DL / PET / VM / LDPE / LLDPE” was obtained. However, this layer configuration is merely an example for explanation, and various variations are possible.
[0042]
After this laminated film is folded in half and cut in half, it runs parallel to the horizontal direction with a vertical gap, and the two folded films for the bottom are inserted from the sides of the two running films to seal the necessary parts. The standing pouch shown in FIG. 1 was manufactured by trimming, punching, and cutting into individual bags. Note that the orientation in the running direction of the laminated film was set to be slightly larger than the orientation in the width direction so that tearing in the horizontal direction could be made smoothly when individual bags were formed.
[0043]
As shown in FIG. 1, an overhanging region (2) projecting from the upper side of the bag is provided on the right half of the upper side of the standing pouch (1).
[0044]
An unopened discharge path (3) serving as a spout is formed inside the region of the overhang region (2) near the side of the bag. The discharge path (3) is formed by forming an unsealed part at the time of sealing, like the contents accommodating part of the bag main body part. In addition, the bag side of the discharge passage (3) is rounded so as to be concave inward including the seal part on the bag side, and is shaped so that it can be easily inserted or hooked into the convex of the refill container mouth. .
[0045]
Then, in the region near the center of the bag of the overhang region (2), the region above the easy tear line (6) described later becomes the pull tab portion (4) for opening.

In FIG. 1, the finger hook (5a) is drawn in a single circle, but the non-sealed portion having a diameter of 24 mm, which is slightly larger than the diameter of the through hole, is provided on the laminated body of the front and back films before punching. After the through hole is installed by punching, the load on the finger when the finger is put on the through hole (finger hook (5a)) is reduced by the ring-shaped non-seal portion.
[0048]
Between the pull tab portion (4) and the bag support knob portion (8), the lower end side of the end edge of the pull tab portion (4) is set as the start end A, and is close to the front end side of the discharge passage (3). An easy tear line (6) to reach the perforation is formed in a U shape so as to bypass the lower half side of the finger hook (5a).
[0049]
The end B of the easy tear line (6) is provided with a notch (7) for opening the front end side of the discharge passage (3), and this notch (7) is formed by punching into a triangular shape. V notch.
[0050]
The notch (7) across the discharge passage (3) (which is an unsealed portion) on the opposite bank in the horizontal direction, as shown in FIG. 1, is the bag side edge seal portion and the distal end side of the discharge passage (3) The boundary line is formed as a polygonal line in the shape of> when viewed from the notch (7) side.
[0051]
Therefore, when the tip side of the discharge passage (3) is torn through the easy tear line (6) from the start A to the end B and further through the notch (7), as shown in FIG. When tearing in the horizontal direction, even if the tear line of at least one of the front and back films may be shifted above or below the horizontal direction as shown in FIG. 2 (B) or FIG. 2 (C), > It strikes one of the two sides of the polygonal line and is guided and converged at the apex, so the pull tab (4) as a whole, including the upper piece on the tip side of the discharge channel (3), must be smoothly torn off. Will be able to.
[0052]
In FIG. 1, the upper side opposite to the side where the overhang region (2) of the bag is provided is set as a non-seal part, which is used as a filling port (9). After filling the contents from the filling port (9), the upper side (filling port (9)) is sealed and the whole is sealed.
[0053]
A large number of easy-opening standing pouches with pull tabs of the above structure are prepared, filled with detergent or human or pet shampoo to make a package, and 200 of them are randomly extracted and the pull tab part (4 ) When pulling the pull tab part (4) through the finger hook (5a), the tear line on one or both of the front and back films is shown in Fig. 2 (b) and (c). 3) In some cases, the position near the tip side was slightly out of alignment with the horizontal direction.
