Description

  TECHNICAL FIELD The present invention relates to a packaging bag in which a jelly-like solid food is sealed, and has a suppressing means for suppressing popping out of the contents when the contents are pushed out of the packaging bag after opening the packaging bag.

  Conventionally, as packaging containers for storing jelly-like solid foods (hereinafter referred to as jelly-like solids), cup-shaped packaging containers such as coffee jelly and fruit juice jelly are often used. Packaging bags are also used for convenience and convenience.

  Recently, in order to replenish nutrients such as proteins and vitamins as health foods, packaging containers containing jelly-like solids different from liquids have been sold. For example, there are various types of pouches that can be handled easily and can be made into a mouth as if drinking. The contents are poured into the mouth from the spout of the spout while compressing the torso of the bag with fingers, especially softening the jelly-like solids, giving them fluidity and eating as if drinking. Is.

  The jelly-like solid is used in the form of a packaging container suitable for each because of its hardness and fluidity.

  In particular, packaging bags in which jelly-like solids are sealed are often used for directly putting contents into the mouth. The lower part of the packaging bag is compressed with fingers, the contents are moved to the opening part of the bag, and the contents are sucked into the mouth from the opening part. You can eat the contents easily. Packaging bags are widely used because they are inexpensive. However, when opening the packaging bag, there is a problem that the contents pop out to compress the lower part of the packaging bag, and the fingers and clothes are soiled. In addition, when the contents are pushed out of the packaging bag and eaten, there is also a problem of clogging in the throat due to vigorous jumping out.

  In order to solve these problems, for example, there is a proposal to prevent the contents from popping out when the width of the opening portion is made narrower than the width of the housing portion of the packaging bag and the lower portion of the bag is compressed. This is a proposal to provide a heat seal portion so as to narrow the opening portion of the housing portion. However, since the width of the unsealed portion is determined by the volume of the contents, it is necessary to create a heat seal plate to match each heat seal portion. In addition, there is a problem in that it takes time and labor to attach and remove the heat seal plate on the bag making machine and lower the production efficiency (Patent Document 1).

  In addition, a packaging bag with a pour-out path has been proposed in order to further subdivide it into a pour-out path portion by heat sealing in a linear fashion to narrow the pour-out path and prevent the contents from popping out. It is a proposal of a seasoning whose contents are liquid. This is different from the gist of the packaging bag of the present invention. However, even if it is used for a jelly-like solid, there is a problem that when the lower part of the bag is compressed, the jelly-like solid becomes linear and the texture of the original jelly-like solid disappears (Patent Document 2).

  In view of the problem of the background art, there is a demand for a packaging bag that has a suppressing means for suppressing popping out of contents and is highly convenient.

By making the side heat seal part 12 on one side into a continuous triangular shape 20, the jumping out of the contents can be suppressed. Further, since the extruded content is a single lump having a shape substantially the same as the shape of the accommodating portion, it is easy to bite when put into the mouth. Moreover, it is possible to prevent clogging in the throat by suppressing the jumping out vigorously.

  FIG. 5 is an explanatory view showing an example of the packaging bag of the present invention. It is explanatory drawing which shows an example of the packaging bag 3 of this invention. The side heat seal part 12 of the packaging bag 1 of FIG. 1 is made into the continuous circular arc shape. That is, it has an arc-shaped jagged shape. Even with such an arc shape, the jumping out of the contents can be suppressed as in the triangular shape. It can also be trapezoidal. However, the square shape has a problem that a jelly-like solid remains in the corner of the corner. The shape of the side heat seal portion is particularly preferably a shape in which no jelly-like solid remains.

  FIG. 6 is an explanatory view showing an example of another form of the packaging bag of the present invention. It is explanatory drawing which shows an example of the packaging bag 4 of this invention. The packaging bag 4 shows a standing bag 50. In order to form the storage portion, while the front film and the back film are overlapped, a bottom tape 60 for forming the bottom portion of the storage portion is inserted, and the sides and the bottom portions on both sides are heat-sealed. After filling the jelly-like solid, the standing bag 4 is heat-sealed on the upper part of the housing. At the upper part of the side heat seal part, a notch part for opening and a polychuck for resealing are provided. Because of its shape, the standing bag 50 can accommodate a larger volume of contents than the three-side seal bag and the four-side seal bag, and has a self-supporting property.

  Next, as an opening means, in addition to the notch portion 14, the cut line 15 is a half cut line by laser light irradiation, or a method of laminating a uniaxially stretched film in a laminated film of a pouch (in this case, Used such that the stretching direction matches the opening direction). These may be used alone, or may be used in combination such as lamination of the notch 14 and the notch line 15 or the notch and the uniaxially stretched film.

  The notch part 14 can be formed using the method of forming with a blade, and the method of forming by laser processing. Moreover, although the notch part 14 can use notches, such as a 1 character shape or V shape, in particular, a shape is not specifically limited, If it is a shape which has the pointed part in the cutting direction, it can be used.

  The cut line 15 is not limited to a straight half-cut line, and may be an intermittent half-cut line such as a perforation. The half-cut line can be formed by a method of forming with a blade and laser processing. Examples of the type of laser beam include carbon dioxide laser, YAG laser, and excimer laser having a continuous or pulse oscillation type, and polyolefin film, polyethylene terephthalate film, etc. used particularly for the packaging bag of the present invention. A carbon dioxide laser having a wavelength of 10.63 μm (infrared rays) that is absorbed by each of the above films can be suitably used.

The packaging bag of this invention is a packaging bag which sealed the jelly-like solid substance. It is a re-sealable packaging bag that can easily open the packaging bag and prevents the contents from popping out and soiling fingers and clothes when eating the contents. By making the side heat seal part forming the housing part into a continuous uneven shape, the contents are prevented from popping out. It is possible to prevent clogging of the throat by suppressing the contents from popping out vigorously. Moreover, since the extruded content is a single lump that is substantially the same as the shape of the accommodating portion, it is easy to bite it when it is put in the mouth.

  As a film used for the packaging bag according to the present invention, a film usually used for the packaging bag can be used, and the structure of the film is a laminate of at least a base material layer and a sealant layer.

Furthermore, for example, in order to prevent vitamins from being destroyed by external light such as vitamin preparations or gases such as oxygen or water vapor, a laminated film in which aluminum foil is sandwiched with the above plastic film is used as a film structure. Sometimes used. In addition, when the packaging bag is required to have transparency and a gas barrier property against oxygen or water vapor, a film having a deposited film made of an inorganic oxide is used instead of the aluminum foil. Examples of the inorganic oxide include aluminum oxide (Al ₂ O ₃ ), silicon oxide (SiO ₂ ), magnesium oxide (MgO), and the like.

  Examples of films having gas barrier properties include aluminum vapor-deposited polypropylene film, aluminum vapor-deposited polyethylene terephthalate film, and when transparency is required, silica-deposited polyethylene terephthalate film, alumina-deposited polyethylene terephthalate film, magnesium oxide-deposited polyethylene terephthalate film, silica A vapor-deposited nylon film, an alumina vapor-deposited nylon film, a magnesium oxide vapor-deposited nylon film, or the like can be used.

  In order to make these laminated materials into a bag shape, a heat sealing method is usually used. A polyolefin resin is generally used as the sealant layer of the laminated material. Specifically, low density polyethylene resin, medium density polyethylene resin, linear low density polyethylene resin, ethylene-vinyl acetate copolymer, ethylene-based resin such as ethylene / α-olefin copolymer, homopolypropylene resin, propylene Polypropylene resins such as ethylene random copolymer, propylene / ethylene block copolymer, and propylene / α-olefin copolymer can be used. A film of these resins or a multilayer film obtained by combining these resins can also be used.

  Examples of the adhesion method between the base material layer and the sealant layer include a wet lamination method, a dry lamination method, a non-solvent dry lamination method, a hot-melt lamination method, an extrusion lamination method, and a sandwich lamination method using the extrusion lamination method. A known method such as can be used.

  Next, a method for producing a packaging bag will be described. This will be described with reference to the packaging bag 1 shown in FIG. As shown in FIG. 1, a single laminated film is folded at the bottom, heat-sealed on both sides, and formed into a bag with an open top. The side heat seal plates on both sides are formed in a continuous triangle shape in advance and attached to the side heat seal part on the bag making machine to form a bag that suppresses popping out of the contents by heat sealing. Can do. Further, in order to provide resealing means, after the film is folded back, a polychuck is incorporated between the front and back films and thermally bonded, and then heat sealing is performed with the polychuck sandwiched between the sides. Thereafter, a notch serving as an opening means is provided on the upper side of the heat-sealed side. The jelly-like solid is filled from the opening at the top of the bag. Thereafter, in order to seal the opening, the packaging bag 1 in which the jelly-like solid material is sealed is obtained by heat-sealing the upper part.

  In addition, the cut line for tearing the opening part of the housing part is preliminarily placed in a desired part of the base material layer of the laminated film with a half-cut line or a perforation line with a laser beam, and heat-sealed with a desired dimension to form a bag. Moreover, after making into a bag shape, you may put a half cut line or a perforation line in a desired site | part.
