Description

  The present invention relates to a pouch. In particular, the present invention relates to a pouch that contains a plastic film as a base material, can store liquid, and can be refilled into another container, and can perform the transfer operation easily and stably.

  A pouch is a packaging bag made of a laminate of plastic film as a base material, and various forms are used for various purposes and are indispensable for modern life.

  For example, it is also used as a liquid container, and widely used in the food field such as beverages and retort foods such as curry. In the toiletry field, a variety of products are sold in supermarkets, drug stores, and convenience stores. It is crowded.

  The advantages of pouches are that they are cheaper than containers such as cans and bottles, can be handled with a fine-grained material structure depending on the required quality, and are lightweight and space-saving before filling and distribution and storage. Can be mentioned.

  In addition, high-definition printing on the layer visible from the surface can improve the image of the product and display necessary information about the contents. Bar code printing is used for product distribution and marketing. It is a source of information.

  Conventionally, liquid bottles such as detergents, bleaches, softeners, shampoos, rinses, and syrups have become established in daily life as products. Bottles for liquids such as detergents, bleaches, softeners, shampoos, rinses, syrups and the like are stored in dedicated containers each having an easy-to-use shape.

  The dedicated container has a solid structure and is therefore expensive, so a refillable pouch that refills only the contents has been commercialized so that it can be used repeatedly when the contents are gone. Often sold.

  Disposing of the bottle after using up the contents is also a problem from the viewpoint of environmental protection, and attention is paid to separation disposal, reduction of the total amount of waste, and promotion of recycling. Particularly in recent years, refillable pouches have been used and developed from the viewpoint of environmental compatibility.

  In this way, refillable pouches are more economical than purchasing new bottles and storage containers each time, and are environmentally adaptable from the perspective of reducing waste. It has become something to follow.

  However, the purchaser has to take time and effort to transfer the contents contained in the refill pouch to a bottle or storage container. At this time, since the refill pouch is flexible with a plastic film as a base material, refilling work requires attention at the same time as its convenience, and sometimes leakage of contents and associated finger or surrounding contamination. It has been regarded as a problem to cause such problems.

When actually performing the refilling operation, bring the opened pouch closer to the opening of the container to be refilled and control the flow rate of the liquid in the contents, while paying attention to the filling amount of the container to be refilled. It was necessary to work carefully with both hands while paying.

  Patent Document 1 proposes a packaging container having a plastic film as a base material and having a self-standing property and having a mouth plug that can be repeatedly opened and closed, but is not necessarily intended as a container for refilling. The workability of refilling was not considered.

  For example, some of the refillable pouches on the market are designed to be easy to pour out, so the convenience of refilling work to refill the contents from the refill pouch for containers that are used repeatedly It was not necessarily in consideration of sex.

  In addition, in some refilling pouches, the emphasis was placed solely on manufacturing inexpensively, so the convenience of refilling work was not necessarily considered.

  The support portion (3) is provided so as to protrude outward from the vertical side surface on the handle (1) side. The support portion (3) has a ring (11). The handle (1) is held through the ring (11) with a finger to support the pouch (100), and the contents are plugged (4). It is possible to take it out from.

  The pouch (100) is provided with a self-supporting property by the left and right vertical side surfaces and the bottom surface structure including the heat seal (36), and the support portion (3) stably holds the pouch (100) with one hand. It is possible to perform refilling work easily and stably.

  Moreover, the pouch according to the present invention is made by heat sealing using a plastic film as a base material as described at the beginning of the embodiment for carrying out the invention.

  Therefore, at least a plastic film substrate and a heat-sealable sealant layer are required as a laminate constituting the pouch. If the plastic film itself has heat sealing properties, a single layer is also possible.

  FIG. 18 is a partial cross-sectional schematic view for explaining one embodiment of a laminate constituting the pouch according to the present invention. Each component will be individually described with reference to FIG.

(Plastic film base layer)
The plastic film substrate layer (45) is a film made of a polymer resin composition, for example, polyolefin (polyethylene, polypropylene, etc.), polyester (polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, etc.), polyamide (nylon-6) , Nylon-66, etc.), polyimide, and the like can be used and are appropriately selected depending on the application. Particularly when polypropylene or polyethylene terephthalate is used as the plastic film base layer (45), it is more preferable in terms of film strength and price.

(Sealant layer)
In order to make a pouch, the periphery and the like are bonded by heat sealing. The sealant layer (46) for that purpose is disposed on at least one surface of the laminate, and the two laminates are stacked so that the sealant layers (46) face each other, and heated and pressurized to heat-seal each other. Can be made to make bags. However, when the pouch is not a laminate but a single plastic film layer, a plastic film having heat sealability is selected.

  As a material of the sealant layer (46), a polyolefin resin is generally used among thermoplastic resins, and specifically, a low density polyethylene resin (LDPE), a medium density polyethylene resin (MDPE), a linear low Ethylene resins such as density polyethylene resin (LLDPE), ethylene-vinyl acetate copolymer (EVA), ethylene-α olefin copolymer, ethylene-methacrylic acid resin copolymer, blend resin of polyethylene and polybutene, Polypropylene resins such as homopolypropylene resin (PP), propylene-ethylene random copolymer, propylene-ethylene block copolymer, and propylene-α-olefin copolymer can be used.

  For the formation of the sealant layer (46), a molten resin can be formed using an extruder or the like to form a layer on the laminate (50). Alternatively, the sealant layer (46) can be formed on the inner surface of the pouch of the laminate (50) by laminating materials that have been formed into a film in advance by laminating.

  In this case, for example, an adhesive layer (44) can be provided between the plastic film base layer (45) and the sealant layer (46). For this adhesion, each layer of the laminate can be adhered and laminated by, for example, a dry coating method.

  The sealant layer (46) is welded and bonded by applying heat and pressure, and when the laminated body (50) is made into a pouch, the sealant layers (46) are placed facing each other and heated. A pouch can be obtained by sealing. Therefore, the sealant layer becomes the inner surface of the pouch.

(Gas barrier layer)
For the purpose of improving the storage stability of the contents, an opaque layer that blocks ultraviolet rays, such as a colored film, can be provided in the laminate (50) if necessary. Or a gas barrier layer (42) can be provided in a laminated body (50).

  As the gas barrier layer (42), a gas barrier film (43) obtained by providing a gas barrier layer (42) of an inorganic compound on the surface of the plastic film (41) can also be used. As the gas barrier layer (42), a metal film such as aluminum deposited on the surface of the plastic film (41) or a metal foil such as aluminum foil can be disposed in the laminate.

When the gas barrier film (43) is used, the gas barrier layer (42) can be composed of a vapor deposition layer and a coating layer of an inorganic compound. After the anchor coat is provided on the plastic film (41), the vapor deposition layer and the coating layer are sequentially formed. Provide.

  For example, urethane acrylate can be used for the anchor coat layer of the gas barrier film (43). For the formation of the anchor coat layer, a coating method using a printing technique such as gravure coating with a paint in which a resin is dissolved in a solvent can be used, and a coating film can be formed using a generally known coating method.

  As a method of forming a vapor deposition layer, an inorganic compound such as SiO or AlO is coated on a base film provided with an anchor coat layer using a vacuum vapor deposition method, and an inorganic compound layer is formed by a vacuum vapor deposition method. it can. The thickness of the vapor deposition layer is preferably 15 nm to 30 nm.

  As a method for forming the coating layer, an aqueous solution or water / alcohol containing at least one of a water-soluble polymer and (a) one or more alkoxides or hydrolysates thereof, or (b) tin chloride. A coating agent mainly composed of a mixed aqueous solution is applied onto a film and dried by heating to form an inorganic compound layer by a coating method to form a coating layer. At this time, the adhesion with the anchor coat layer can be improved by adding a silane monomer to the coating agent.

  The inorganic compound layer has a gas barrier property only by a coating film formed by a vacuum deposition method, but a coating layer that is an inorganic compound layer formed by a coating method is formed on the vapor deposition layer that is an inorganic compound layer formed by a vacuum deposition method to form a gas barrier layer (42 ).

  By combining these two layers, a reaction layer of both layers is formed at the interface between the inorganic compound layer by the vacuum deposition method and the inorganic compound layer by the coating method, or the inorganic compound layer by the coating method becomes an inorganic compound layer by the vacuum deposition method. A dense structure is formed by filling and reinforcing defects such as pinholes, cracks, and grain boundaries, or by reinforcing them, so that high gas barrier properties, moisture resistance, and water resistance are achieved, and flexibility that can withstand deformation is achieved. Therefore, it can be suitable as a pouch.

  When SiO is used as the gas barrier layer (42), for example, the coating is transparent, so that the contents can be seen from the outside of the packaging bag. These may be properly used depending on the application and required quality.

  In addition, when a metal foil is not used as the gas barrier layer (42), for example, when necessary, in addition to suitability for heating by a microwave oven, there is no trouble in using a metal detector for a product. There is also an advantage in the resilience of the shape when the pouch is pushed from the outside and used.

  The plastic film used for the gas barrier film (43) is a film made of a polymer resin composition, such as polyolefin (polyethylene, polypropylene, etc.), polyester (polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, etc.), polyamide ( Nylon-6, Nylon-66, etc.), polyimide, and the like can be used and are appropriately selected according to the application. Particularly when polypropylene or polyethylene terephthalate is used as the plastic film (41), it is more preferable in terms of film strength and price.

  The gas barrier film (43) can be laminated by providing, for example, an adhesive layer (44) in the laminate (50). At this time, for example, each layer can be bonded and laminated using a dry coating method. Moreover, in the example shown in FIG. 14, since there is a plastic film (47) further on the outside of the pouch, the front and back of the gas barrier film (43) are not limited.

(Print layer)
Necessary information on image enhancement as a product, contents, or transfer thereof can be provided by printing on a layer visible from the outside of the plastic bag as needed.

  For example, in the layer structure of the laminate (50), the plastic film (47) can be laminated by providing the printing layer (48). If a transparent film is used for the plastic film (47), the plastic film (47) is arranged so as to be on the outside of the pouch (50) according to the present invention. Therefore, it is possible to obtain an excellent design property even in appearance without being exposed, and thus excellent in friction resistance.

  The plastic film (47) that can be used at this time is a film made of a polymer resin composition, such as polyolefin (polyethylene, polypropylene, etc.), polyester (polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, etc.), polyamide, etc. (Nylon-6, nylon-66, etc.), polyimide and the like can be used, and can be appropriately selected according to the required quality and application.

  Particularly when polypropylene or polyethylene terephthalate is used as the plastic film (47), it is more preferable in terms of film strength and price.

  Here, the printing method and the printing ink for forming the printing layer (48) are not particularly limited, but from the known printing method and printing ink to the plastic film (47). In consideration of printability, design properties such as color tone, adhesiveness, influence on contents, safety as a container, or required physical and chemical resistance, it may be appropriately selected.

  As the printing method, for example, a gravure printing method, an offset printing method, a gravure offset printing method, a flexographic printing method, an inkjet printing method, or the like can be used. Of these, the gravure printing method can be preferably used in terms of productivity and high definition of the pattern.

  Thus, according to the present invention, in the refilling operation of the liquid contents, the pouch can be stably held with one hand, and the refilling operation can be performed easily and stably. It is possible to provide.

Evaluation methods, evaluation items, and evaluation criteria are as follows.
(Evaluation method)
As contents assuming a detergent, 5 liters of water was filled in a pouch and sealed. Next, the work of refilling the contents of the pouch, that is, 5 liters of water, into a separate 900 g container for detergent was performed.

(Evaluation item)
Three items were included: ease of holding, ease of pouring, and wrist support.

(Evaluation criteria)
Sensory evaluation is made with a maximum of 5 points.
In order from good, 5 points, 4 points, 3 points, 2 points, and 1 point were assigned.
Since Comparative Example 1 is a conventional type, three points were used as blanks.
For all the evaluation items, those with a score of 4 or more were OK, and those with 3 or less were NG.

  The evaluation results are shown in Table 1.

  From the results shown in Table 1, the pouches according to the present invention, that is, Examples 1 to 9, obtained an evaluation of 4 points or more for all items, and were OK. In comparison, Comparative Example 1 is evaluated as a blank, and the evaluation points are all 3, which is insufficient because no support portion is provided. Moreover, the comparative example 2 which remove | deviates from the range of the angle X pinched | interposed by the horizontal line (17) of a support part fulcrum by this invention, and a support part center line (J) was NG determination.

Consider the evaluation results in more detail.
Example 1 is an evaluation that may be better than blanks in all three items. It is thought that the effect of the support part appears. Therefore, the determination is OK.

  Example 2 is a good evaluation compared to the blank in all three items. It is thought that the effect of the support part appears. Therefore, the determination is OK.

  Example 3 is an evaluation that may be better than blanks in all three items. It is thought that the effect of the support part appears. Therefore, the determination is OK.

  Example 4 is an evaluation that may be better than blanks in all three items. Therefore, the determination is OK. In particular, it is highly evaluated for ease of pouring and wrist support. It is considered that the effect of the support portion appears, and in particular, the angle X is in the optimum range.

  Example 5 is an evaluation that is better than the blank in all three items. Therefore, the determination is OK. The evaluation of the ease of holding and the support of the wrist is particularly high. It is considered that the effect of the support portion appears, and in particular, the relationship between the angle X and the distance Y is in the optimum range.

  Example 6 is an evaluation that is better than the blank in all three items. Therefore, the determination is OK. In particular, it is highly rated for ease of holding and wrist support. It is considered that the effect of the support portion appears, and in particular, the relationship between the angle X and the distance Y is in the optimum range.

  Example 6 is a better evaluation than blank in all three items. Therefore, the determination is OK. The evaluation of ease of holding is particularly high. It is considered that the effect of the support portion appears, and in particular, the angle X is in the optimum range.

  Example 7 is a better evaluation than the blank in all three items. Therefore, the determination is OK. The evaluation of ease of holding is particularly high. It is considered that the effect of the support portion appears, and in particular, the angle X is in the optimum range.
