Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a standing pouch used for hermetically packaging contents having fluidity such as a liquid, and more particularly, to a method of easily transferring contents to another container such as a bottle when opened. The present invention relates to a standing pouch having a thinly projecting spout so that it can be replaced.

[0002]

2. Description of the Related Art Conventionally, standing pouches are self-supporting and have the characteristics of a three-dimensional container despite being formed of a soft packaging material such as a plastic film. Also widely used as containers. However, with regard to the opening, a method of removing the entire upper part using the notch part provided on the upper part of the standing pouch and opening it, cutting off the corner of the upper seal part with scissors and opening it, and opening it with a spout In addition, a method in which a spout with a cap made of a plastic molded product or the like is separately attached to the upper opening by thermal bonding or the like in advance, and the cap is removed to open the cap, has been adopted. .

[0003]

However, the method of removing and opening the entire upper portion of the standing pouch is problematic in that, especially when the contents are liquid, the pouch is soft and easily overflows from the upper portion when held by hand. There is.
Also, the method of cutting off the corner of the upper seal portion and opening it and using it as a spout can reduce the risk of accidentally overflowing the contents as compared with the above method in that the opening can be narrowed. However, when the opening is narrower, the film on both sides of the opening is more likely to adhere to each other on the inner surface, so it is difficult to continuously pour the film to the end with a stable flow. It is necessary to squeeze and push out, and when squeezed by hand, it instantaneously and vigorously flows out. Therefore, when transferring to another container or the like, there is a problem that the contents are easily spilled.

[0004] In addition, a method in which a spout with a cap or the like is attached to the upper opening in advance by heat bonding or the like and the cap is removed to open the opening is performed in advance by adjusting the size of the opening or the like to determine the properties of the contents or the like. Since a stable shape can be set so as to be suitable for the pouring condition, the safety and stability of pouring are superior to those of the above method. But,
When attaching a spout made of such a plastic molded product to a standing pouch, the manufacturing process becomes complicated, and at the same time, the packaging bag is bulky and the filling of the contents is usually performed.
Since it is necessary to perform the process from a spout having a small hole diameter, a special filling device is required, and further, the cost of the spout is increased, so that there is a drawback that the cost for packaging is significantly increased.

The present invention has been made to solve such a problem, and an object of the present invention is to eliminate the need for a separate spout of a molded product or the like, and to easily fill the contents. In addition, at the time of use, a thin and protruding spout can be easily formed simply by cutting off a part of the heat seal portion at the top of the pouch, and the tip of the spout can easily be opened. It is an object of the present invention to provide a standing pouch excellent in suitability for transfer and the like, in which an outlet can be inserted into a mouth of a bottle or the like so that it can be safely and smoothly poured out from the opening to the end.

[0006]

The above objects can be attained by the present invention described below. That is, according to the first aspect of the present invention, the bottom portion is formed in a gusset format in which the film is folded inward, the body portion is formed of two front and rear wall films, and the upper opening portion is hermetically sealed by heat sealing. In a standing pouch of the type, the upper heat seal pattern used for sealing the opening is formed at the upper edge of the wall film so that the entire width of the opening can be heat-sealed, and at the portion connected thereunder, A neck-shoulder-shaped non-seal portion is formed so as to form a narrowly protruding spout in the opening portion, and the outside of the neck-shoulder-shaped non-seal portion has a predetermined width. A perforation line along the line of the neck / shoulder-shaped non-seal portion or a cut-out display line by printing for cutting out while leaving the heat-seal portion is provided in the upper heat-seal portion area. Consisting standing pouch according to claim.

By adopting such a configuration, there is no need to attach a separate spout made of a plastic molded product or the like, and the standing pouch can be easily manufactured in the same manufacturing process as a normal standing pouch. Filling and sealing is easy, and when using a standing pouch in which the contents are hermetically sealed, a perforated line along the line of the neck / shoulder-shaped non-seal part provided in the upper heat seal part area, or by printing By simply cutting off a part of the upper heat seal part with hands or scissors according to the cutout display line, a thinly projected spout is formed at the top of the pouch, and further, by cutting off the tip of the spout,
The spout can be easily opened. Therefore, even when the contents are transferred to another container such as a bottle, the spout can be inserted into the mouth of the container, so that the contents can be safely transferred to the end without spilling outside.

According to a second aspect of the present invention, the spout is opened near the tip of the neck portion of the neck / shoulder-shaped non-sealing portion so as to cross the neck portion. The cutout display line or half-cut line for opening by printing, or the cutout display line or half-cut line for opening, and at least one end of the cutout display line or half-cut line for opening, or the cutout for opening A notch is provided at a position where a line or a half-cut line intersects with a perforated line provided to form the thin protruding spout, or a cutout display line by printing. And a standing pouch according to claim 1.

By adopting such a structure, in addition to the above-mentioned functions and effects, when using a standing pouch in which the contents are hermetically sealed and packaged, when the formed spout is opened, a portion near the base is erroneously cut off. Without this, the spout can be cut out reliably and easily near the tip of the spout to open a spout of a predetermined length.

The perforated line is generally formed by alternately arranging a linear cut line and a connecting portion. However, the present invention is not limited to this, and the entire perforated line is provided. , The shape of the break line can be constituted by a single shape such as a linear shape, a curved shape, a U-shape, or a combination of a plurality of shapes. And the half-cut line is, for example, in all layers of the pouch wall film,
Cut about の of the thickness of all layers, such as the base film layer on the surface with excellent strength, by mechanical method or laser light irradiation from the surface side, and tear it along the half cut line. It was made. Further, the shape of the notch may be any of an I-shape, a V-shape and the like, and may be a notch having an acute angle portion in the tearing direction.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention, such as a method for manufacturing a standing pouch, will be described below. First, the material used for producing the standing pouch of the present invention is not particularly limited, and any of the materials used for known standing pouches can be used as they are, and the types of contents to be packaged and the heat treatment after filling are used. A suitable material can be freely selected and used according to use conditions such as presence or absence. Usually, a laminated film mainly composed of plastic is used for the standing pouch, and specific examples of the configuration include the following.

(1) ON film / adhesive / L·LDPE
Film (sealant layer) (2) ON film / adhesive / uniaxially stretched HDPE film / adhesive / L / LDPE film (3) ON film / adhesive / uniaxially stretched PP film / adhesive / L / LDPE film (4) ON film / Adhesive / Uniaxially stretched PP film / Adhesive / Aluminum foil / Adhesive / L·LDPE film (5) ON film (silica vapor deposition layer) / Adhesive / Uniaxially stretched HDPE film / Adhesive / L·LDPE film (6) ON film / anchor coat layer / co-extrusion coat layer (HDPE layer / L / LDPE layer) (7) ON film / anchor coat layer / co-extrusion coat layer (HDPE layer / LDPE layer) / adhesive / L ・LDP
E film (8) PET film / adhesive / aluminum foil / adhesive / ON film / adhesive / L / LDPE film (9) PET film / adhesive / aluminum foil / adhesive / ON film / adhesive / CPP film (10) PET films / adhesives / EVOH films / adhesives / ON films / adhesives / CPP films, and the like, but are not limited thereto, and various combinations of laminated films can be used.

In the above description, the ON film is a biaxially stretched nylon film, the L / LDPE is a linear low density polyethylene, the HDPE is a high density polyethylene, the LDPE is a low density polyethylene, the PP film is a polypropylene film, and the PET film is 2 The axially stretched polyethylene terephthalate film and the EVOH film indicate a saponified ethylene-vinyl acetate copolymer film, and the CPP film indicates a non-stretched polypropylene film. Also,
The anchor coat is a kind of primer coat which is pre-coated on the base film side in order to improve adhesiveness when laminating a resin by extrusion coating.

In the construction of the laminated film, ON
Films and PET films are used as base films to impart mechanical strength and printability to pouches,
By using the film and the uniaxially stretched PP film so that the stretching direction matches the tearing direction when opening the pouch, the directionality of the tearing can be further stabilized. Then, an aluminum foil, a silica vapor-deposited layer, an EVOH film, and the like are laminated to provide gas barrier properties. In addition, as the sealant layer, two examples of an L-LDPE film and a CPP film have been described. However, the L-LDPE film has heat sealing stability and content resistance, such as stress cracking resistance to a surfactant. The CPP film is excellent in heat resistance and low odor, and is suitable for packaging of contents requiring these properties.

In the sealant layer, in addition to the above, depending on the contents to be filled, ethylene / α-olefin copolymer, ethylene / vinyl acetate copolymer, ethylene / acrylic acid copolymer, ethylene / acrylic ester copolymer may be used. Polymers, ionomers, polyester resins and the like can also be appropriately selected and used. In particular, ethylene-α-olefin copolymers polymerized using metallocene catalysts have excellent low-temperature heat sealability and hot sealability because the molecular weight distribution is narrow and the copolymerization ratio is stable. This is preferable in that a stable seal can be obtained.

Next, a method for manufacturing the standing pouch of the present invention, which is manufactured using the above-described laminated film, will be described. As described above, the standing pouch of the present invention can be safely and easily transferred to another container such as a bottle when opening and using a standing pouch in which contents such as a liquid are hermetically sealed and packaged. In addition, a spout having a thin and protruding shape can be formed in a part of the upper part of the pouch by a simple operation. For this purpose, the heat seal pattern of the upper heat seal portion is changed to a predetermined shape and sealed, and the upper heat seal portion has a perforation line for cutting to remove unnecessary portions and form a spout, or A cut-out display line by printing is provided, and further, a cut-out display line for opening by cutting, a half-cut line, a notch, and the like for cutting out and opening the tip of the spout are provided.

When manufacturing such a standing pouch, there are roughly two methods. The first method is to use a standing pouch using two front and rear wall films and a bottom material film that are appropriately printed, laminated by lamination, and finished to a predetermined size (width) in the same manner as a normal standing pouch. A bottom pouch (gusset type) and a body are heat-sealed with a bag making machine to produce a standing pouch having an open top, and then a filling and sealing machine is used to fill the contents from the top opening and then heat-seal the predetermined pouch. This is a method in which the upper opening is heat-sealed and sealed with a seal head formed in a pattern. Incidentally, the perforation line for cutting provided in the upper heat seal portion and the notch are preferably provided in the upper heat seal portion after the filling seal, but before the filling seal, that is, a predetermined in-line or off-line at the time of bag making. It may be provided in advance at a position.

The second method is different from the first method in that the time for heat-sealing the upper heat-sealing portion is changed. Is a method in which heat sealing is performed in advance using the heat sealing pattern. In this case, in order to fill the contents, all or a part of one of the right and left body heat seal portions is opened in an unsealed state, and the contents are filled from this portion with a filling and sealing machine. Fill and then heat seal the part to seal. In the case of employing this method, the perforation line for cutting provided in the upper heat seal portion and the notch also follow the heat seal according to the predetermined heat seal pattern of the upper heat seal portion before filling the contents, that is, at the time of bag making. And can be processed inline.

Further, as described above, even when the upper heat seal portion is heat-sealed before filling the contents, depending on the shape of the heat seal pattern, the unsealed portion for filling the contents is not necessarily provided in the body heat seal portion. It is not necessary to provide an opening, and an unsealed opening may be provided at the top. That is, a neck-shoulder-shaped non-seal portion and a heat seal portion outside the neck / shoulder for forming a spout provided in the heat seal pattern of the upper heat seal portion of the pouch,
As shown in FIG. 1 described below, when provided at the corner of the upper part of the pouch, the upper heat seal pattern is formed in a shape limited to this part, heat sealed, and the remaining part is filled with contents. By using it as an unsealed opening, the contents can be filled from this portion without any problem and heat sealed. By adopting such a method, the heat sealing of the opening after filling the contents can be performed not at the side edge portion of the pouch having a step in the thickness of the film but at the upper portion, so that there is an advantage that a stable seal can be obtained. is there.
