However, the refillable pouch described in Patent Document 1 requires the wall film 5 to be formed with a bulging portion C, and the spout portion 6 is an easy-opening made of a combination of a notch and a half-cut line by laser light irradiation. Therefore, the cost must be increased accordingly.
The problem of the present invention is that it is not necessary to mold the wall film, or to provide a notch or a half-cut line by laser beam irradiation, and can be manufactured at a lower cost than that described in Patent Document 1. An object of the present invention is to provide a refillable pouch that can be refilled without dirtying hands and can take out almost all of the content even if the wall film has no bulge.

The invention according to claim 1 solves the above-mentioned problem, and is a bag body in which two pieces of triangular wall films are overlapped to heat-seal the periphery, and viscous contents are accommodated therein, An opening planned portion is formed at one apex angle of the bag body, and the opening opening portion is configured such that the apex angle vicinity of the two heat seal portions adjacent to each other across the apex angle has an easy peel property. Then, the viscous content is pushed toward the opening portion by grasping the bag body, and the opening portion is subjected to cohesive failure or delamination by receiving a force received from the pushed viscous content, and the opening The gist of the present invention is a refillable pouch characterized by opening a planned portion.

According to the refilling pouch of the present invention, the tapered contour portion is formed by inserting the planned opening portion, which is a tapered contour portion having an easy peel seal portion, into the mouth of the bottle and grasping the refill pouch. The easy peel seal part is cohesively broken or delaminated to open a tapered outline, thereby refilling viscous contents such as detergent and shampoo without soiling the hands.

In the present invention, refill pouch intended to form the shape of a triangular bag, also a refill pouch of the present invention, it is also possible that a triangle to one side of the square to form a composite shape of a square and a triangle, which is connected is there. Further, the tip of the tapered contour portion does not necessarily have an acute angle, and may be formed round.

  The refillable pouch of the present invention is preferably housed in a rigid exterior container made of carton, plastic or the like and double-wrapped. As a result, it is possible to prevent unexpected opening due to a strong external force during transportation, storage or sales.

  Further, the refillable pouch of the present invention can be packaged in a self-supporting state by being accommodated in a box, a cup, or the like, or accommodated in a standing pouch.

  It is also possible to accumulate a plurality of refillable pouches of the present invention and package them in an outer container.

The refilling pouch according to the present invention is a bag body in which two triangular wall films are overlapped and the periphery is heat-sealed, and the viscous content is accommodated therein, and is opened at one apex angle of the bag body. A planned portion is formed, and the planned opening portion is configured such that the vicinity of the apex angle of the heat seal portions adjacent to each other with the apex angle therebetween has an easy peel property. The object is pushed toward the planned opening, and the planned opening is subjected to cohesive failure or delamination under the force received from the viscous content pushed at that time, and the planned opening is configured to open. Therefore, by inserting the planned opening portion, which is a tapered contour portion having an easy peel seal portion, into the mouth portion of the bottle and holding the refilling pouch, the viscous content is pushed toward the tapered contour portion, The peel seal portion by cohesive failure or delamination is opened the contour of the tapered, it is possible to refill detergent, viscosity contents such as shampoo without thereby pollute the hand. In addition, since the viscous contents are squeezed out, refilling can be performed with almost no viscous contents remaining in the pouch even for highly viscous contents. Further, since it is not necessary to form a wall film or to provide a notch or a half-cut line by laser light irradiation, it can be manufactured at low cost. In addition, the wall film of the pouch can be made much thinner than conventional refillable pouches.

  In the embodiment of the refilling pouch of the present invention shown in FIGS. 2 and 3, the refilling pouch 20 includes a triangular bag body 21, and a viscous content 22 is accommodated in the bag body 21. Yes. The bag body 21 is formed by stacking two wall film 23 and sealing the periphery. Further, the seal portion 25 around one corner portion (tapered contour portion) 24 of the triangular bag body has an easy peel property, and the viscous content 22 is moved toward the corner portion 24 by gripping the bag body 21. The seal portion 25 is configured to undergo cohesive failure or delamination by receiving a force received from the viscous content pushed at that time, and the corner portion is opened.

  The wall film 23 consists of two layers, an inner layer and an outer layer. The heat-sealable resin film used as the inner layer will be described. As such a film, for example, low density polyethylene, medium density polyethylene, high density polyethylene, linear (linear) low density polyethylene, polypropylene, ethylene- Vinyl acetate copolymer, ionomer resin, ethylene-ethyl acrylate copolymer, ethylene-acrylic acid copolymer, ethylene-propylene copolymer, methyl pentene polymer, one or more kinds of other resin films or Sheets can be used. The thickness of the film is 50 μm or more, desirably 100 μm or more, more preferably 130 μm to 500 μm. The film used as the inner layer desirably has a thickness of about 2 to 20 times, preferably about 4 to 10 times that of the film used as the outer layer. In the present invention, by using a film having a thickness as described above, the rigidity, strength, etc. of the film are increased, and when the pouch is configured in combination with the physical properties of a resin film having excellent strength, It has the advantage that the posture maintenance is good, the refilling work of the consumer is easy, and the handling at the store in the distribution process is convenient, and the inner layer has the aroma retaining property of the viscous contents, etc. Is to hold. By the way, in the present invention, among the films as described above, the sheet-sealing film used as the inner layer is mainly composed of linear (linear) low-density polyethylene or ethylene-vinyl acetate copolymer. Most preferably, a film or sheet is used. That is, the film or sheet mainly composed of the above-mentioned linear (linear) low-density polyethylene or ethylene-vinyl acetate copolymer has adhesiveness, so that it has less propagation of breakage and improves impact resistance. In addition, since the inner layer is always in contact with a detergent, a shampoo, etc., it is also effective for preventing deterioration caused by environmental stress cracking.

  Next, a resin film having rigidity and excellent strength used as an outer layer will be described. As such a film, a resin film having excellent properties such as mechanical properties, physical properties, and chemical properties is used. Thru | or a sheet | seat can be used.

Thus, as the resin film or sheet, any of an unstretched film or a stretched film stretched in a uniaxial direction or a biaxial direction can be used. In the present invention, the thickness of the resin film or sheet may be any thickness that can maintain the minimum necessary regarding strength, rigidity, and the like.

  The easy peel seal portion 25 around the corner portion 24 is composed of the wall surface films 23, 23 and the easy peel property imparting layer 26 interposed between the wall surface films 23, 23. Here, as the easy peel property imparting layer 26, for example, polypropylene / propylene-ethylene copolymer, block polypropylene copolymer / block polypropylene copolymer and blend of polyethylene copolymer or polybutene copolymer, random polypropylene copolymer / polypropylene / ethylene. -Vinyl acetate copolymer, blend of polyethylene and amorphous polystyrene, blend of polyolefin resin and polybutene-1 polymer, polyolefin / low density polyethylene adhesive layer / ethylene-vinyl acetate copolymer and polybutene-1. Examples include blends, polyolefins / low density polyethylene adhesive layers / ethylene-vinyl acetate copolymers and polypropylene blends, and the like.

  In addition, the easy peel seal portion 25 reduces the seal temperature of the seal portion 25 of the corner portion 24 without interposing the easy peel imparting layer 26 therebetween, so that the seal portions around the portions other than the corner portion 24 It can also be formed lower than the sealing strength.

  FIG. 4 shows a state in which detergents, shampoos, and the like are being refilled using the refilling pouch shown in FIGS. The corner portion 24 having the easy peel seal portion 25 is inserted into the mouth portion of the bottle 27, and the viscous content 22 is pushed toward the corner portion 24 by grasping the refilling pouch, thereby coagulating and breaking the easy peel seal portion 25. Alternatively, the corner portions 24 are opened by delamination so that the viscous contents 22 such as a detergent and a shampoo can be refilled without soiling the hands.

  In addition, since the viscous contents are squeezed out, refilling can be performed with almost no viscous contents remaining in the pouch even for highly viscous contents.

  Further, since it is not necessary to form a wall film or to provide a notch or a half-cut line by laser light irradiation, it can be manufactured at low cost. In addition, the wall film of the pouch can be made much thinner than conventional refillable pouches.

Furthermore, as shown in FIG. 5 , it is also possible to form a round shape without making the tip of the corner portion an acute angle.

  The refilling pouch 20 of the present invention is preferably housed in a rigid exterior container made of carton, plastic or the like and double-wrapped. As a result, it is possible to prevent unexpected opening due to a strong external force during transportation, storage or sales.
