Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a packaging bag used for seasoning for refilling, retort food, cosmetics, detergents, and the like, which has a low production cost and allows easy removal of contents.
[0002]
[Prior art]
Packaging bags used for seasonings for refills, retort foods, cosmetics, detergents, etc. are required to be able to take out the contents while maintaining a stable flow until the end. .
Conventionally, a plastic resin-made hollow cylindrical nozzle is attached to the spout of a soft resin film packaging bag (Japanese Patent Laid-Open No. 5-132069), or a soft resin film packaging bag. What formed the hollow (semi-) cylindrical extraction pipe line is proposed. (For example, JP-A-8-2538)
In addition, a packaging bag provided with a bulging portion that bulges outward at the spout of the packaging bag (JP-A-6-127560), and a refilling packaging bag provided with a reinforcing mechanism at the spout of the packaging bag are also proposed. . (JP-A-7-2260)
[0003]
[Problems to be solved by the invention]
However, attaching a hollow cylindrical nozzle to a soft packaging bag or forming a hollow (semi) cylindrical dispensing pipe requires a special process and increases costs, and the resulting packaging bag However, since it has a hollow cylindrical nozzle and an extraction pipe line, there are problems such as being bulky and requiring extra space when transported and stored.
In addition, in the case where the bulging portion is simply provided at the outlet of the packaging bag, the outlet tends to bend easily and the flow path of the contents becomes unstable at the time of extraction, while the reinforcement mechanism is simply provided at the outlet of the packaging bag. There was a problem that the opening property of the spout became worse at the time of opening.
[0004]
Therefore, the object of the present invention can be manufactured without requiring a special process, and when the packaging bag is opened and the contents are taken out, the spout can be easily formed and the spout is bent. An object of the present invention is to provide a packaging bag that can easily remove contents while maintaining a stable flow until the end, and that is not bulky during transportation and storage.
[0005]
[Means for Solving the Problems]
In the present invention, in a packaging bag made of a plastic film and provided with a spout above the packaging bag, an embossing opening assist mechanism and a bending prevention mechanism are provided at the spout, thereby solving the above-mentioned problems of the prior art. The intended refill packaging bag is obtained.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
There is no restriction | limiting in particular as a plastic film used for the packaging bag of this invention, What is normally used for a packaging bag can be used.
Examples of the plastic material suitable for constituting the plastic film include crystalline polypropylene, crystalline propylene-ethylene copolymer, crystalline polybutene-1, crystalline poly4-methylpentene-1, low-, medium-, Or polyolefins such as high density polyethylene, ethylene-vinyl acetate copolymer (EVA), ethylene-ethyl acrylate copolymer (EEA), ion-crosslinked olefin copolymer (ionomer); polystyrene, styrene-butadiene copolymer Aromatic vinyl copolymers such as polyvinyl chloride, vinyl halide polymers such as vinylidene chloride resin; nitrile polymers such as acrylonitrile-styrene copolymer, acrylonitrile-styrene-butadiene copolymer; nylon 6, nylon 66 , Para or metaxylylene adipa Such polyamides de, polyethylene terephthalate, polyesters polytetramethylene terephthalate; various polycarbonates; may be mentioned thermoplastic resins such as polyacetal such as polyoxymethylene or the like.
Films made of these plastic materials are used as unstretched or uniaxially or biaxially stretched films.
[0007]
The plastic film used in the packaging bag of the present invention can be constituted by laminating these plastic films in a single layer or by laminating two or more kinds, and one or more kinds of these plastic films, A metal foil such as aluminum, paper, cellophane, or the like can also be laminated.
As a preferable plastic film, for example, a stretched nylon film has an outer layer and a two-layer structure having a polyolefin film such as low density polyethylene or polypropylene as an inner layer, or a stretched polyester film has an outer layer and a polyolefin film is an inner layer. And those having a three-layer structure in which a metal foil such as aluminum is laminated between outer layer films. When manufacturing these laminated | multilayer films, an anchor agent can also be interposed between each layer as needed.
[0008]
Whether the plastic film has a single layer or what kind of layer structure should be selected according to the properties of the contents to be filled in the packaging bag. For example, it is as low as a packaging bag for refilling detergent. For cost-required products, use a laminated film with a two-layer structure, and for retort pouches filled with contents that require preservation, such as seasonings and retort foods, three or more layers including aluminum foil A laminated film may be used.
[0009]
Hereinafter, the characteristics of the packaging bag of the present invention will be further described with reference to the drawings. FIG. 1 is an overall view showing an example of a packaging bag of the present invention, and FIGS. 2 to 4 are partial enlarged views of nozzle-shaped spout portions showing other examples of the packaging bag of the present invention. FIG. 5 is a diagram showing an example of the cross-sectional shape of the opening assist mechanism provided at the spout in the packaging bag of the present invention, and FIG. 6 shows the cross-sectional shape of the bending prevention mechanism provided adjacent to or adjacent to the opening assist mechanism. It is a figure which shows an example.
In these drawings, reference numeral 1 denotes a packaging bag, reference numeral 2 denotes a spout, reference numeral 3 denotes an opening assisting mechanism, reference numeral 4 denotes a bending prevention mechanism, reference numeral 5 denotes an easy-opening processing part, and reference numeral 6 denotes a heat seal part.
[0010]
In the packaging bag of the present invention, a nozzle-shaped spout 2 is provided above the bag 1, and the spout 2 is preferably provided at a corner portion above the bag as seen in FIG. What is necessary is just to set suitably the dimension and shape of a nozzle-shaped spout according to the kind of the content to be filled, and the dimension of the opening part of a container.
[0011]
In the present invention, the spout 2 is provided with an opening auxiliary mechanism 3 and a bending prevention mechanism 4 by embossing.
By providing the opening assisting mechanism 3 at the spout 2 of the packaging bag, it is possible to prevent the spout from being closed when the packaging bag is poured out, and the cross-sectional area of the spout is increased, so that the content is high in viscosity. But it becomes easier to pour out. Further, by providing the folding prevention mechanism 4 adjacent to or adjacent to the opening assist mechanism 3, the outlet 2 can be prevented from being bent and blocking the flow path when the contents are poured out, and the stable dispensing direction can be obtained. And we can get the amount dispensed.
[0012]
There are no particular restrictions on the shape, dimensions, and cross-sectional shape of the opening assist mechanism 3 as seen from the upper surface. Examples of the shape seen from the upper surface include a substantially rectangular shape as shown in FIGS. 1 and 2, a circular shape as shown in FIG. Such a substantially triangular shape can be used. When the opening assisting mechanism 3 is extended to the inside of the bag as shown in FIGS. 7 and 8 to be described later, it is preferable because the contents can be easily poured out.
The cross-sectional shape of the opening assist mechanism 3 is not particularly limited, and may be, for example, a convex shape on the outside as shown in FIGS. As can be seen from FIG. 5C, it is preferable to provide a convex crease at the center of the opening assist mechanism 3 because the opening and bulge restoration properties are particularly good. As shown in FIG. 5, the opening assist mechanism 3 can be formed on both sides of a plastic film (packaging material) forming a packaging bag, or can be formed only on one side of the packaging material.
[0013]
In the packaging bag of the present invention, the folding preventing mechanism 4 is provided adjacent to or adjacent to the opening assisting mechanism 3, but the number of the bending preventing mechanisms installed, the shape as viewed from above, the dimensions, the cross-sectional shape, etc. are not particularly limited, and one Alternatively, two or more bending prevention mechanisms 4 can be provided. Moreover, as the shape seen from the upper surface, for example, a rod-like shape as shown in FIGS. 1, 2 and 4 and a corrugated shape as shown in FIG. These bend prevention mechanisms 4 are not limited to one type, and a configuration in which two or more kinds of bend prevention mechanisms 4 having different shapes as shown in FIG. 4 are provided in combination. Examples of the cross-sectional shape of the bending prevention mechanism 4 include those shown in F, G, and H of FIG.
[0014]
7, 8, and 9 are diagrams showing another embodiment of the present invention, in which a folding preventing mechanism 4 is provided in the opening assist mechanism 3.
In the embodiment of FIG. 7, the opening assisting mechanism 3 has an arrowhead shape, and a bending prevention mechanism 4 is provided at the center and below both sides thereof.
Further, in the embodiment of FIG. 8, the inclination angle of the triangular opening assist mechanism 3 is such that the perpendicular drawn from the apex angle to the base is 40 to 50 degrees with respect to the horizontal direction, and the two sides on both sides thereof Is provided with a bending prevention mechanism 4 substantially in parallel with each other.
As shown in FIG. 9, a narrow bending preventing mechanism 4 is provided in the wide opening assisting mechanism 3.
In these embodiments, the opening assist mechanism 3 has an arrowhead shape or a triangular shape, but an appropriate shape such as a rhombus shape or an oval shape can be adopted, and the outer shape of the bending prevention mechanism 4 can be adopted. The shape, the cross-sectional shape, and the angle to be provided can be appropriately selected and employed.
Furthermore, as shown in FIG. 10, the bending prevention mechanism 4 can be crushed or the inner layer of the bending prevention mechanism 4 can be heat sealed to increase the strength.
[0015]
In order to provide an opening assist mechanism and a bend prevention mechanism in the packaging bag of the present invention, a plastic film constituting the packaging bag is heated before bag making, a jig having a desired shape is pressed and embossed, or vacuum or compression is used. A method of deep drawing using air or the like and then cooling can be used, but an embossing method is preferred from the viewpoint of simplicity of operation. In this case, in addition to the method of heating the plastic film, a jig having a desired shape can be heated by various methods such as high-frequency heating or heater heating.
The plastic film provided with the opening assist mechanism and the bending prevention mechanism is made by a bag making machine, and after filling the contents, the filling port is heat sealed and sealed.
[0016]
In the spout 2 of the packaging bag of the present invention, an easy-opening processing portion 5 can be provided in order to facilitate the opening of the packaging bag.
Examples of such an easy-opening processed portion include an I-shaped or V-shaped notch formed at the bag end, a perforation or score that crosses the spout, other thinned weakened processed portions, or a combination thereof. Examples of the method for forming such an easy-opening portion include (1) laser processing with a focus beam or a kaleido beam, (2) mechanical processing with a cutter, a grindstone, etc. (3) thermal processing with a heat bar or the like.
When forming an easy-opening part such as a perforation or a score that crosses the spout, if the easy-opening part that completely penetrates the plastic film is formed, the type of contents filled in the packaging bag Depending on the case, the contents may be leaked, or the drop strength after filling the contents may be unfavorable. In such a case, the occurrence of such a problem can be prevented, for example, by forming the packaging bag with a laminated film and subjecting only the outer layer film constituting the laminated film to an easy opening process.
The easy-open processing part that crosses the spout includes instability in the processing state in focus beam laser processing, generation of fumes, misalignment of the processing position on the front and back when used as a packaging bag, machining scraps and packaging material In order to avoid problems such as generation of powder and instability of the processing state due to resin adhesion due to heat processing of the heat bar, it is preferable to form by laser processing with a kalide beam.
And it is preferable to form a plurality of easy-opening portions on the outer surface and / or inner surface of the film by laser processing with a kalide beam, or on the outer layer film and / or the inner layer film of the laminated film.
[0017]
Next, an example of forming the easy-opening processed part by laser processing using a kalide beam will be described with reference to the drawings. 11 is a diagram showing a cross-sectional shape crossing the opening direction of an easy-opening portion formed by laser processing with a kalide beam, FIG. 12 is a diagram showing a cross-sectional shape along line AA in FIG. 11, and FIG. 13 is an array of easy-opening processing portions The schematic diagram which shows a state, and FIG. 14 are sectional drawings for demonstrating the relationship of the trough part and peak part which comprise the weakening layer of an easy-open process part.
For example, as shown in FIG. 11, the easy-open processing portion 5 is a weakened layer composed of a plurality of pairs of valley portions 7 and mountain portions 8 in a state adjacent to each other in the direction crossing the opening direction or at a small interval. The depth of the valley portion 7 and the height of the mountain portion 8 are changed, and the depth of the valley portion and the height of the mountain portion are gradually changed along the opening direction of the arrow B as shown in FIG. To form.
[0018]
According to the above configuration, in the easy-opening processed portion 5 formed in a plurality, as shown in FIG. 13, a relatively deep portion 71 indicated by a solid line in a state of being adjacent or spaced apart along the opening direction, and a dotted line The relatively shallow portion 72 shown in FIG. 5 is formed, but the relatively deep portion 71 of the adjacent easy-opening portions is formed as a continuous, close or overlapping state in a state of being adjacent or spaced apart. Only the shallow portion 72 does not overlap with each other. Therefore, it is possible to prevent unsuccessful opening due to the shallowness of the easy-opening processing portion, which occurs when the easy-opening processing portion 5 is formed by one.
[0019]
As shown in FIG. 14, when the average thickness of the film forming the weakened layer is t 0 , the bottom thickness of the valley portion 7 is t 1 , and the top thickness of the peak portion 8 is t 2 , t 1 The value of / t 0 is 0.9 to 0.1, especially 0.8 to 0.5, and the value of t 2 / t 0 is 1.05 to 2.0, especially 1.1 to 1.8. It is preferable.
When the value of t 1 / t 0 is larger than the above range, it is insufficient in terms of tear initiation and tear guiding properties. On the other hand, when this value is smaller than the above range, the bag breaking strength of the weakened layer and Impact resistance is reduced.
Furthermore, if the value of t 2 / t 0 is smaller than the above range, the protective effect of the weakened layer is lost, the toughness is lowered, the bag breaking strength is lowered, and the tearing guideability is easily lowered. If the value is larger than the above range, the strength of the peak portion becomes too high, stress concentration on the valley portion is likely to occur, and processing becomes difficult, which is not practical.
[0020]
Also, when the packaging bag is composed of laminated film, depending on the type of plastic material used as the outer layer and inner layer film (for example, when nylon film is used as the outer layer and linear low density polyethylene is used as the inner layer), the outer layer When the easy-opening part is formed only on the film, the cut end surface of the inner layer film may not be cut cleanly at the time of opening, and the spout may be in a lint-like state. When the spout is in such a state, it becomes difficult to stably pour the contents because the flow path is disturbed during the pouring. Such a problem can be solved by subjecting not only the outer layer film but also the inner layer film to easy opening. For easy opening processing of the inner layer film, it can be processed from the inner layer film side of the laminated film by a roll, a cutter, a grindstone, or by laser processing, etc., and from the outer layer film side through the outer layer film to the inner layer film You may make it form the easily opened process part which reaches. As shown in FIG. 1, the easy opening portion can be provided in a direction perpendicular to the longitudinal axis of the packaging bag, that is, in the horizontal direction, and as seen in FIG. 2, relative to the longitudinal axis of the spout. You may make it provide in a right angle direction.
[0021]
The easy-opening portion can be formed, for example, simultaneously with the slitter processing, or at the time of bag making by a bag making machine. Moreover, it can also carry out beforehand to the film which comprises an outer layer and / or an inner layer before lamination | stacking of a laminated | multilayer film.
There is no restriction | limiting in particular in the shape of the packaging bag of this invention, For example, a three-side seal, a four-side seal flat bag, a standing pouch etc. are mentioned.
In addition, the contents filled in the packaging bag include not only liquid products but also free-flowing powdery and granular seasonings, retort foods, cosmetics and detergents.
[0022]
【Example】
Next, the present invention will be described with reference to examples, but these examples do not limit the present invention.
(Example 1)
The detergent refill shown in FIG. 1 is performed from a laminated film obtained by laminating a biaxially stretched nylon film having a thickness of 15 μm and a linear low density polyethylene (LLDPE) film having a thickness of 130 μm through a urethane anchor agent by the following steps. A pouch was manufactured.
The laminated film is heated to a temperature 50 to 70 ° C. lower than the melting point of the nylon film, that is, 150 to 170 ° C., and the cross-sectional shape at the time of bag making is shown in FIG. And an opening assist mechanism 3 shown in FIG. 6 and a linear bending prevention mechanism 4 shown in F of FIG. Next, the nylon film layer, which is the outer layer, is irradiated with a carbon dioxide laser to form the easy-open processing part 5, and then the pouch periphery is heated by the bag making machine leaving a part of the upper end of the pouch (detergent filling port). Sealing was performed to obtain the detergent refill pouch shown in FIG.
The pouch was filled with 500 ml of liquid detergent, sealed, and repeatedly dropped 10 times horizontally and inverted from a height of 1.2 m at a temperature of 5 ° C., but there was no leakage of the detergent. The pouch can be easily opened by hand along the easy-opening processing portion 5, and the spout 2 having a large cross-sectional area is easily formed by the opening assist mechanism 3 at the time of opening. Further, the bending prevention mechanism 4 can prevent the spout 2 from being bent, and by simply turning the pouch upside down after opening, the detergent inside can be transferred to the refilling container while maintaining a stable flow to the end. I was able to.
[0023]
(Example 2)
A PET film layer is formed from a laminated film obtained by laminating a biaxially stretched polyethylene terephthalate (PET) film having a thickness of 12 μm and an LLDPE film having a thickness of 130 μm via a urethane anchor agent in the same process as in Example 1. The detergent refilling pouch having the spout 2 shown in FIG. 3 was produced.
Also in this case, the laminated film was embossed by heating to a temperature 50 to 70 ° C. lower than the melting point of the PET film, that is, 170 to 190 ° C.
This pouch can be easily opened by hand in the same manner as the pouch of the first embodiment. At the time of opening, the spout 2 having a large cross-sectional area is easily formed, and the spout is prevented from being bent. The detergent was able to be removed in a stable flow until the end. Further, like the pouch of Example 1, the drop strength after filling with the detergent was also excellent.
[0024]
(Example 3)
From a laminated film in which a biaxially stretched PET film having a thickness of 15 μ, an aluminum foil having a thickness of 7 μ, and a polypropylene (PP) film having a thickness of 70 μ are laminated via a urethane-based anchor agent between the respective layers, A pouch for refilling cooked food (retort pouch) having the spout 2 shown in FIG. 4 was produced with the PET film layer as the outer layer in the process.
This pouch can be easily opened by hand in the same manner as the pouch of Example 2, and the opening 2 having a large cross-sectional area is easily formed at the time of opening, and the bending of the outlet is prevented. Things could be taken out in a stable flow until the end. Also, the drop strength when filling the contents was excellent.
[0025]
The thickness, type, combination, etc. of each film constituting the plastic film as the packaging material of the packaging bag of the present invention can be selected widely according to the properties of the intended refill packaging bag. It goes without saying that the present invention is not limited to those described in each example.
