Description

  The present invention relates to a packaging bag, and more particularly to a packaging bag that is easy to hold when pouring contents from a spout.

  In recent years, from the viewpoint of saving resources, a packaging bag of a soft synthetic resin film such as a standing pouch that accommodates contents for refilling has been widely used. These packaging bags are formed with spouts, such as spouts, to transfer the contents to containers such as plastic bottles.

  However, since a packaging bag such as a standing pouch is soft, it is difficult to grasp the body part in which the contents are stored. The transfer work is not easy.

  Therefore, in Patent Document 1, a constricted part is formed in the body part, and a handle made of a rigid member is attached along the side seal part, so that it is excellent in self-supporting and easy to hold when pouring contents. A standing pouch has been proposed.

Utility Model Registration No. 3185296

  However, in the standing pouch described in Patent Document 1, the design of the packaging bag is restricted, and it is necessary to attach a rigid member to the side seal portion. For this reason, it is desired to realize a packaging bag that can be easily held when transferring contents with a simpler configuration.

  This invention is made | formed in view of said situation, and it aims at providing the packaging bag which can be easily hold | maintained with a simple structure when transferring the contents.

  In order to achieve the above object, the packaging bag of the present invention is a packaging bag in which the edges of the superposed front film and the back film are sealed and provided with a spout, and one or both of the front and back films The thick piece is attached to the vicinity of the seal portion on the upper edge when the contents are poured from the spout, and is provided apart from the seal portion. .

  Thus, by providing the simple structure of the thick piece, when holding the packaging bag, the fingers can be locked to the step on the inner edge of the thick piece. For this reason, it can prevent that a packaging bag slips from a finger.

  Therefore, according to the packaging bag of this invention, when transferring the contents, the packaging bag can be easily held with a simple configuration.

It is a front view of the packaging bag by embodiment of this invention. It is explanatory drawing which shows a mode that the packaging bag was hold | maintained with one hand. (A)-(c) is explanatory drawing which shows the holding position of a finger, and the inclination of a packaging bag.

Hereinafter, embodiments of the extraction packaging bag of the present invention will be described with reference to the drawings.
In FIG. 1, the front view of the packaging bag by embodiment of this invention is shown. As shown in the figure, the packaging bag 10 of this embodiment includes a left seal part 3 and a right seal part 4 in which the edges of both sides of the superposed front film 1 and back film 2 are sealed, A standing pouch 100 having an upper seal portion 5 whose end edge is sealed and further provided with a gusset portion 6 at the lower portion, and the contents are hermetically packaged in a storage portion surrounded by these seal portions. . As shown in FIG. 1, the standing pouch 100 is provided with a spout spout 7 by obliquely cutting off the upper left corner of the drawing where the left seal portion 3 and the upper seal portion 5 meet.
In addition, in the same figure, the code | symbol 2 has pointed out the back side film piled up on the back side of the front side film 1. FIG.

  The front-side film 1 and the back-side film 2 have, for example, dimensions of 200 mm × 300 mm, respectively, and are constituted by a laminated film composed of a heat-sealable sealant layer and a base material layer. It is also possible to provide a print layer and an adhesive layer.

  Various materials and configurations can be adopted for the front film 1 and the back film 2 as long as they can be heat-sealed. Examples thereof include thermoplastic resins such as nylon, linear polyethylene, low density polyethylene, high density polyethylene, polyolefins such as polypropylene, and polyesters such as polyethylene terephthalate. Moreover, the front side film 1 and the back side film 2 can mention the vapor deposition film which is a barrier film, and an aluminum laminate film. Moreover, these plastic films can be constituted by a single layer or by laminating two or more kinds, and are appropriately selected according to the contents.

  The front side film 1 and the back side film 2 in the present embodiment are, for example, a soft polyethylene layer having a thickness of 120 μm as a sealant layer, a nylon layer having a thickness of 15 μm and a polyethylene terephthalate layer having a thickness of 12 μm as a base material from the inner surface side. It has a configuration in which the layers are sequentially stacked.

  And the thick piece 8 is attached to the inner surface of both the front side film 1 and the back side film 2, respectively. In FIG. 1, the outlines of the two thick pieces 8 are overlapped and indicated by broken lines. The thick piece 8 may be formed of the same material as that of the inner surfaces of the front and back films 1 and 2 and thermally welded to the inner surface, or may be formed of the same material as that of the inner surface or a different material. May be adhered to the inner surface.

  The thick piece 8 is formed by punching a soft polyethylene sheet having a thickness of 0.8 mm, for example, and has a curved shape with a length of 130 mm and a maximum width of 7.5 mm. The total thickness of the two thick pieces 8 is 1.6 mm, and a sufficient level difference is formed at the edge of the thick piece 8 to hold the fingers when the packaging bag 10 is picked. In order to hold the packaging bag 10 reliably, it is preferable that the maximum width of the thick piece 8 is 1 to 50 mm, and the step formed by the thick piece 8 is 0.5 to 10 mm.

  The thick piece 8 is attached in the vicinity of the right seal portion 4 which is the upper side when pouring the contents from the spout 7, apart from the right seal portion 4. The right seal portion 4 is a seal portion that is not adjacent to the corner where the spout 7 is formed, and is the seal portion farther from the extraction port 7 of the two left and right seal portions 3 and 4.

  Moreover, as shown in FIG. 1, the thick piece 8 is arrange | positioned along the seal | sticker part 4 of the right side of the packaging bag 10, and is the center part of the direction along the seal | sticker part 4, ie, the half of the height of a packaging bag. It is arranged to include the position of. The inner edge 8a on the central side of the packaging bag 10 of the thick piece 8 has a shape curved in a convex shape toward the right seal part 4 side. In particular, the inner edge 8a of the thick piece 8 has a curved shape with an increased curvature from the center of the thick piece 8 toward both ends, as shown in FIG.

  Since the thick piece 8 of this embodiment is attached to the inner surface side, the appearance of the packaging bag 10 is not affected. For this reason, the design of the packaging bag 10 is not restricted. Moreover, since only the simple structure called the thick piece 8 is added and the form of the front side film 1 and the back side film 2 of the packaging bag 10 is not changed, the packaging bag 10 is not disturbed. A productivity of 10 can be maintained.

  In FIG. 2, a mode that the packaging bag 10 of this embodiment was hold | maintained with one hand is shown. As shown in the figure, the inner edge 8a of the thick piece 8 on the central side of the packaging bag 10 is disposed at a position where the finger F can reach. In other words, the thick piece 8 is closer to the right seal part 4 side than the position where the finger F of one hand H reaches when the front and back films 1 and 2 are sandwiched by the one hand H from the right seal part 4 side. Has been placed. In particular, it is preferable that it exists in the range of 3-50 mm from the inner edge of the right seal part 4. By arranging the thick piece 8 in this way, the finger F can be locked to the step of the inner edge 8a of the thick piece 8 when the packaging bag 10 is held. For this reason, it is possible to prevent the packaging bag 10 from slipping from the finger F.

  Further, as shown in the figure, since the thick piece 8 is disposed away from the right seal portion 4, when the inner edge 8a of the thick piece 8 is picked with a finger F, the right seal portion 4 is It will come into contact with the palm P.

The position picked by the finger F is shifted to the right side of the drawing from the center of gravity G of the packaging bag 10. For this reason, a force is applied to the finger F from the thick piece 8 in the left direction in the drawing with the portion where the right seal portion 4 contacts the palm P as a fulcrum (arrow α). This force α is received by the finger F because the finger F is locked by the step of the inner edge 8 a of the thick piece 8. On the other hand, at the position lower than the finger F, a force is applied from the right seal portion 4 to the right side of the drawing with the portion picked by the finger F as a fulcrum at the portion where the right seal portion 4 contacts the palm P (arrow) β). This force β is received by the palm P. Thereby, the packaging bag 10 can be easily hold | maintained in two places, the finger F and the palm P. FIG.
In FIG. 2, the center of gravity G of the packaging bag 10 is shown in the center of the packaging bag 10 for convenience, but the actual center of gravity changes with the movement of the contents.

  As described above, the packaging bag 10 can be held at two locations of the finger F and the palm P, so that the packaging bag 10 is stably held and the inclination angle of the packaging bag 10 is easily controlled. be able to. Thereby, when transferring the contents of the packaging bag 10 to a container such as a bottle, the contents can be made more difficult to spill.

  Next, the characteristic of the curved shape of the thick piece 8 will be described with reference to FIG. FIG. 3 (a) schematically shows the packaging bag 10 when the upper portion A of the thick piece 8 is picked with fingers, and FIG. 3 (b) shows the vicinity B of the center of the thick piece 8 with fingers. The packaging bag 10 is schematically shown when picked, and FIG. 3C schematically shows the packaging bag 10 when the vicinity C of the lower portion of the thick piece 8 is picked with fingers.

  First, as shown in FIG. 3 (a), when the packaging bag 10 is lifted by picking up the vicinity A of the thick piece 8 with fingers, the package 10 is slightly lifted as shown in FIG. Tilt. At this time, since the inner edge 8a is greatly curved near the end of the thick piece 8, the tangent Ta of the inner edge 8a in the vicinity A of the upper portion of the thick piece 8 and the gravity direction G are substantially orthogonal. For this reason, when the vicinity A of the upper part of the thick piece 8 is held with fingers, the fingers are stably locked at the step of the inner edge 8a of the thick piece 8, and the packaging bag 10 is prevented from slipping.

  Further, as shown in FIG. 3B, when the packaging bag 10 is lifted by picking around the center B of the thick piece 8 with fingers, the packaging bag 10 is caused by its own weight as shown in FIG. The right seal part 4 is inclined so as to be substantially horizontal. At this time, the tangent line Tb of the inner edge 8a near the center B of the thick piece 8 and the gravity direction G are substantially orthogonal. For this reason, even when the central portion B of the thick piece 8 is held with fingers, it is effective that the fingers are stably locked at the step of the inner edge 8a of the thick piece 8 and the packaging bag 10 slides. Is prevented.

  As shown in FIG. 3 (c), when the packaging bag 10 is lifted by picking the lower portion C of the thick piece 8 with fingers, the packaging bag 10 is caused by its own weight as shown in FIG. It is greatly inclined so that the spout 7 is directed almost directly below. At this time, the tangent line Tc of the inner edge 8a near the lower portion C of the thick piece 8 and the gravity direction G are substantially orthogonal. For this reason, even when the lower portion C of the thick piece 8 is held with fingers, it is effective that the fingers are stably locked at the step of the inner edge 8a of the thick piece 8 and the packaging bag 10 is slid. Is prevented.

  Thus, in the packaging bag 10 of this embodiment, the thick piece 8 is arrange | positioned along the right side seal part 4, The inner edge 8a has a curved shape especially, and a curvature becomes large as it goes to both ends from a center. Therefore, even if it is held at any part of the thick piece 8, the tangential direction of the inner edge 8a at the holding part and the direction of gravity can form an angle close to a right angle.

  Further, in the case of a refill pouch having a large capacity exceeding 1 L, an internal capacity of a volume several times that of a container for bottles or the like is accommodated. The transfer of the contents from such a large-capacity refilling pouch to a container such as a bottle is carried out in a plurality of times instead of transferring the entire amount at once. When the contents of the packaging bag 10 according to the present embodiment are transferred in, for example, three times, the first time, as shown in FIG. 3 (a), the upper portion A of the thick piece 8 is sandwiched and held with fingers. In the second time, as shown in FIG. 3 (b), the central portion B of the thick piece 8 is sandwiched and held with fingers, and in the third time, as shown in FIG. The lower portion C of the thick piece 8 may be held with fingers. In any of the first to third times, the finger is stably locked at the step of the inner edge 8a of the thick piece 8.

  In addition, since the packaging bag 10 can be held at two locations, the fingers and the palm, the inclination angle of the packaging bag 10 can be easily controlled. Thereby, when the contents of the packaging bag 10 are transferred to a container such as a bottle in a plurality of times, handling of the packaging bag 10 is facilitated, and the contents can be made difficult to spill.

  Next, Table 1 shows the amount of material reduced when the thicknesses of the soft polyethylene layers of the front film 1 and the back film 2 in this embodiment are reduced.

  From Table 1 above, it can be seen that each time the thickness of the soft polyethylene layer of the front film 1 and the back film 2 is reduced by 10 μm, the amount can be reduced by about 1.1 g.

  On the other hand, the thick piece 8 also functions as a reinforcing member for the trunk of the packaging bag 10. For example, the total mass of the two thick pieces 8 provided in the packaging bag 10 is about 1 to 2 g. When the thickness of the soft polyethylene layer of the front side film 1 and the back side film 2 is reduced by about 10 to 20 μm, the standing shape cannot be maintained in the packaging bag 10 not provided with the thick piece 8. Since the thick piece 8 can maintain the standing shape of the packaging bag 10 as a reinforcing member, the front film 1 and the back film 2 can be reduced in weight by the mass of the thick piece 8 or more. For this reason, the front film 1 and the back film 2 can be made thin while maintaining the standing shape of the packaging bag 10, and the increase in weight due to the attachment of the thick piece 8 can be offset.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention. In the embodiment described above, an example of a packaging bag of a standing pouch has been described. However, in the present invention, the shape of the packaging bag is not limited to this, and for example, a flat pouch sealed with four sides, a pouch with a gusset, and a folded back It can also be applied to a packaging bag in which three sides of the film are sealed.

  Moreover, although the embodiment mentioned above demonstrated the example which provided the thick piece in both the front side film and the back side film, in this invention, you may provide a thick piece material only in one of a front side film and a back side film. .

  In the above-described embodiment, the thick piece provided on the front film and the thick piece provided on the back film are arranged at positions where they overlap each other, but the thick pieces may be arranged so as to be shifted from each other. Good.

  In the above-described embodiment, the example in which the thick pieces are provided on the inner surfaces of the front film and the back film has been described. However, in the present invention, the thick pieces are provided on the outer surface of one or both of the front film and the back film. May be. Moreover, you may provide a thick piece in the state inserted in the laminated structure of one or both of a front side film and a back side film.

  Further, in the above-described embodiment, the example in which the thick piece is arranged along the seal portion has been described. However, in the present invention, the extending direction of the thick piece is not limited to this, for example, the thick piece is sealed. You may make it extend in the direction which makes a perpendicular direction or an angle with respect to the direction along a part. Moreover, a thick piece is not limited to arrangement | positioning of one place, You may distribute and arrange | position to multiple places.

  In the above-described embodiment, an example in which a thick piece curved in a crescent shape has been described, but in the present invention, the shape of the thick piece is not limited to this, for example, a string, a circle, a square, Or a strip shape may be sufficient. Further, the inner edge may be curved and the outer edge may be linear. Furthermore, the shape of the inner edge of the thick piece is not limited to a curve, and for example, a shape obtained by bending a straight line into a polygonal line or a waveform may be used. Moreover, the coupling | bonding of a linear shape part and a curve-shaped part may be sufficient.
