Japanese Patent No. 5715283 JP 2000-43900 A

  The main object of the present invention is to enable easy and quick packaging and convenient use for reuse in a packaging bag having a structure in which a part is broken and opened.

  For this purpose, the inner lid portion integrally connects the pair of upper edge portions provided at the upper end portion of the bottomed bag-like flat bag body and the inner side surfaces at the lower ends of the pair of upper edge portions. A flap portion suspended from one of the outer surfaces of the upper end edge portion, an opening edge portion facing the inner surface of the flap portion and communicating with the storage space in the bag body, and the opening edge Provided with a pasting means that is provided on a surface of the part facing the flap part and affixes the flap part, and the inner lid part is formed with an opening means for opening the storage space by opening the inner lid part, The upper end edge portion is provided with a string body extending in the width direction of the upper end edge portion, and has an integrated portion integrated with the upper end edge portion at both ends in the longitudinal direction of the string body. Detaching the portion having the conversion portion from the upper edge Is a packaging bag stage is formed.

  In this configuration, when packaging a product or the like, the flap portion is raised to store the product or the like in the storage space from the upper end of the opening edge, and the opening is closed by fixing the flap portion using an attaching means. Since there is an inner lid portion between the inner side surfaces of the upper edge portion above the flap portion, the storage space is in a sealed state that cannot be opened unless a part thereof is broken. At the time of opening, the inner lid portion is opened by the opening means to open the storage space.

  In particular, when reusing, in addition to holding the string body provided at the upper edge, if the integrated part of one end in the longitudinal direction of the string body or the integrated part of both ends is separated from the upper edge, the string body Can be used by extending.

  According to this invention, the packaging bag having a structure in which the inner lid portion is opened and opened has the attaching means for closing the opening formed by the flap and the opening edge portion, so that packaging can be performed easily and quickly. In particular, when reusing after opening and opening the inner lid part, hold the string body to the hand, extend the string body to one side in the width direction of the upper edge, the string body in the width direction of the upper edge It can be used conveniently according to the purpose of use because it can be used in at least three ways.

The perspective view of a packaging bag. The longitudinal cross-sectional view of the packaging bag which abbreviate | omitted one part. FIG. The perspective view which shows the seal part of the edge part of a flap part. The front view which shows an example of the aspect at the time of reuse. The perspective view of the principal part of the packaging bag which concerns on another example.

  An embodiment for carrying out the present invention will be described below with reference to the drawings.

  In FIG. 1, the perspective view of the state which extended the upper end part of the packaging bag 11 before packaging is shown. This packaging bag 11 can be suitably used for transportation of goods as well as simply wrapping goods and the like, and has a structure that can be reused after use.

  The packaging bag 11 is made of a suitable synthetic resin sheet that can be welded and is flexible, and has a flat rectangular shape as a whole. Describing the schematic structure, the bottom and both side edges of the packaging bag 11 are closed, and the upper end portion extends in the front and back direction as shown in FIG. 1, but the upper end portion has no opening for storing products or the like. 2 is closed as shown in FIG. The storage of goods and the like is a structure that is performed from the opening 13 inside the flap portion 12 provided on the front side in the front and back direction, in this example. The flap portion 12 is fixed so as not to be easily peeled off once closed. After the flap portion 12 is closed after storing a product or the like, the flap portion 12 cannot be returned to its original state once opened.

  More specifically, the packaging bag 11 has a flat bag body 15 having a bottomed bag shape in a front view and a pair of upper edge portions 16 provided at the upper end of the bag body 15. The bag body 15 and the upper edge 16 are configured by a single sheet material 17 having a rectangular outer shape, as shown in a development view in FIG.

  The bag body 15 has the same width in the entire vertical direction, the bottom is formed by folding, and has a storage space 18 for storing products and the like between the front sheet portion 17a and the back sheet portion 17b that overlap the front and back surfaces. Yes.

  The upper edge 16 is a strip extending in the width direction of the bag body 15, and the length of the upper edge 16 is the same as the length of the bag body 15 in the width direction. The height of the upper edge 16 is shorter than the length of the bag body 15 in the vertical direction, and is set to an appropriate height suitable for holding in the hand.

  Both side edges of the bag body 15 and both side edges of the upper edge 16, that is, both side edges of the packaging bag 11 are closed by a series of seal portions 19 formed in a straight line. The seal portion 19 is formed by integrating overlapping portions of the sheet material 17 and is formed simultaneously with cutting (cutting) in the manufacturing process.

  Further, as shown in the cross-sectional view of FIG. 2, the upper edge 16 has a flat tube shape, that is, a double structure in the front and back direction. The upper edge 16 is formed by welding the upper sheet portions 17c that are folded and overlapped at a position corresponding to the upper edge of the upper edge 16. The welding part 21 which forms the upper end edge part 16 and becomes a boundary with the bag main body 15 is formed in a straight line in the entire width direction of the packaging bag 11 as shown in FIGS.

  Further, the pair of upper edge portions 16 are each provided with a string body 22 extending in the width direction of the upper edge portion 16. The string body 22 is made of a synthetic resin sheet, is in the form of a tape, and is held inside the upper edge 16 that forms a tube. The string body 22 is provided in the upper end position of the upper end edge portion 16 as well. That is, the string 22 is formed in a narrow tape shape lower than the height of the upper edge 16 and is held close to the upper end.

  The string body 22 is held by forming an integrated portion that is integrated with the upper edge 16 at both ends of the string body 22 in the longitudinal direction. Specifically, an end welded portion 23 as an integrated portion is formed at both end portions of the string body 22 so as to be integrated with the upper end corner portion 16a at both ends of the upper end edge portion 16 and the periphery thereof.

  A part surrounding the end welded part 23 is formed with a separating means for separating the part from the upper edge 16. The separating means is composed of perforations 24 that facilitate cutting. The perforation 24 has a quarter arc shape when viewed from the front, and is formed only at the upper edge 16, and the cord 22 has no cut.

  A notch 25 that exposes the string body 22 is formed in an intermediate portion in the width direction of the upper edge 16 that houses the string body 22. The notch 25 is formed in a substantially rectangular shape having an appropriate length. The height in the vertical direction of the notch 25 is a height corresponding to the width of the string body 22 (height in the vertical direction). In other words, the notch 25 is high enough to be blocked by the string body 22, and when the hand is put under the string body 22, the string body 22 is immediately grasped, and when the string body 22 is released, the original state is restored immediately. Structure.

  An inner lid portion 26 that integrally connects them is formed between the lower surfaces of the pair of upper edge portions 16, that is, between the inner side surfaces of the welded portion 21 that forms the upper edge portion 16. The inner lid portion 26 is normally folded in a V-shaped cross section at a position below the upper edge 16. An opening means for opening the inner lid portion 26 is formed at an intermediate position between the upper edge portions 16, that is, a position that becomes a valley when bent into a V-shaped cross section. As the opening means, for example, a perforation or a cut seal can be used. In the illustrated packaging bag 11, a perforation 27 is employed as the opening means. The perforation 27 is formed in a straight line over the entire direction corresponding to the width direction of the bag body 15.

  The length of the inner lid portion 26 in the vertical direction, in other words, the height when the inner lid portion 26 is folded into a V-shaped cross section is set to a length that does not overlap the front sheet portion 17a of the bag body 15 described above.

  One of the outer surfaces of the upper edge 16, that is, the above-described flap portion 12 hangs down from the outer surface of the welded portion 21 that forms the upper edge 16 on the surface side of the pair of upper edges 16. Has been. The flap portion 12 is formed in an appropriate length so as to cover the upper end portion of the bag body 15, and the length of the flap portion 12 corresponding to the width direction of the bag body 15 is the same as the width of the bag body 15.

  A portion of the front surface side (front sheet portion 17 a) of the bag body 15 that faces the inner surface of the flap portion 12 is an opening edge portion 28 that communicates with the storage space 18 inside the bag body 15, and this opening edge portion 28. The above-mentioned opening 13 is between the flap 12 and the flap 12.

  A surface of the opening edge portion 28 facing the flap portion 12 is provided with an attaching means for attaching the flap portion 12. The affixing means is composed of a strip-shaped adhesive layer 29 extending over the entire opening edge 28, and the adhesive layer 29 is protected by a strip-shaped release paper 31. The vertical height of the release paper 31 is set to be larger than the height of the pressure-sensitive adhesive layer 29, and the vertical edge of the release paper 31 protrudes beyond the pressure-sensitive adhesive layer 29 so that the release paper 31 can be easily peeled off. Yes.

  Although the flap part 12 is a structure opened in order to store goods etc. from the opening 13, it is not the structure which all the parts below the welding part 21 open. That is, both sides of the packaging bag 11 have the seal portion 19 as described above, but the portion corresponding to the upper end portion of the opening edge portion 28 in the flap portion 12 is opened by the seal portion 19 as shown in FIG. The upper end portion of the portion 28 is coupled and integrated. In FIG. 4, a portion provided with a dot in addition to hatching is a seal portion 19. Since both of the side edges of the flap portion 12 are integrated with the opening edge portion 28 by the seal portion 19, the upper end of the opening edge portion 28 is located below the flap portion 12 in the vicinity of the seal portion 19. Although maintained, the upper end of the opening edge portion 28 is exposed at the portion between the seal portions 19, and a large opening 13 is obtained.

  The packaging bag 11 configured as described above is used as follows.

  First, when packaging a product or the like, the flap portion 12 is turned up to open the opening 13 and the product or the like is stored in the storage space 18. When used for delivery such as home delivery, products are stored after being wrapped in cushioning material.

  After the merchandise is stored, the opening 13 is closed and the flap portion 12 is fastened to the adhesive layer 29. At this time, since the portion corresponding to the upper end portion of the opening edge portion 28 in the flap portion 12 is coupled and integrated with the upper end portion of the opening edge portion 28 by the seal portion 19, the opening edge portion 28 is accommodated after storing the product or the like. The opening edge portion 28 is naturally closed, and the flap portion 12 is overlapped thereon. For this reason, the flap portion 12 can be attached to the adhesive layer 29 simply and simply by pressing the flap portion 12 after removing the release paper 31.

  Since the length of the flap portion 12, that is, the length in the width direction of the packaging bag 11 is the same as the width of the bag body 15, clean sticking without shifting in the width direction can be easily performed.

  The goods stored in this way are in a sealed state that cannot be opened unless a part of the packaging bag 11 is broken. For this reason, in addition to protecting internal products from moisture and dirt, security can be ensured.

  In addition, the upper end edge portion 16 includes a string body 22 and a notch 25 that exposes the string body 22. The string body 22 is in a tape shape, and the string body 22 is provided at the upper end position in the normal edge portion. In addition, since the vertical height of the notch 25 is a height corresponding to the width of the string body 22, a beautiful appearance that does not allow the notch 25 to be recognized as a hole or a defect can be obtained. In other words, the appearance of a bag that does not have a litter is obtained. In addition, unlike the case where the width of the cord body 22 is wider than the height of the notch 25, when the hand is held in the hand, a hand enters between the cord body 22 and the notch 25, and if the hand is removed, the cord body 22 is removed. Since it closes the notch 25 and returns to the original state, both handleability and good appearance can be achieved.

  When opening, the inner lid portion 26 is opened by the perforation 27.

  After the product is taken out, the role of the packaging bag 11 is temporarily terminated. However, the product is reused (reused), for example, for packaging or carrying the article or collecting garbage.

  When reusing, the strap body 22 provided on the upper edge 16 is lowered by hand, or the strap body 22 is pulled out from the upper edge 16 together with the upper corner 16a of the upper edge 16 to be used as appropriate. Can be used.

  When holding the string body 22 in the hand, as shown in FIG. 5A, the hand may be put under the string body 22 exposed from the notch 25. Since the flap portion 12 is attached to the opening edge portion 28, the flap portion 12 contributes to maintaining the shape of the upper end portion. When the string body 22 is pulled out from the upper edge 16, as shown in FIG. 5B, only one end of the string body 22 can be pulled out and both ends can be pulled out. When only one end is pulled out, the opening at the upper end having the opened inner lid portion 26 is closed, and the cord body 22 can be used for a long time. For example, it can be used like a shoulder bag over the shoulder, so that it can be used differently from the hand . When both ends of the string body 22 are pulled out, the opening at the upper end is similarly closed, and the drawn string body 22 is held in hand, and for example, the string body 22 is used for binding to hold the opening in a closed state. Can be used freely.

  As described above, when this packaging bag 11 is used, packaging that cannot be opened unless a part thereof is broken can be packaged easily and quickly without using a welding apparatus. In addition, when it is reused, it can be used conveniently because various forms of use can be obtained without structural modifications such as using a bag.

  Since it is such a packaging bag 11, in addition to the packaging of goods and luggage as in the above example, for example, in various events such as sports events such as marathon competitions and game watching, volunteer events such as cleaning, etc. It can also be suitably used as a storage bag for storing items to be presented, a storage bag for storing items to be deposited from customers or visitors, etc. Effective use can also be expected.

  The above configuration is one configuration for carrying out the present invention, and the present invention is not limited to the above-described configuration, and other configurations can be adopted.

For example, the packaging bag 11 can be formed in other appropriate shapes such as a shape in which the upper portion is narrow in addition to the shape of the front view.
The notch 25 formed in the upper edge 16 of the bag body 15 is not formed in advance as described above, but can be formed by being separated when needed as shown in FIG. The upper edge 16 may be provided with a notch forming portion 25a for forming a notch 25 that exposes the string body 22. The notch forming portion 25a can be configured by forming a fragile portion made of, for example, a perforation 25b at a site to be cut off.

  The string body 22 may be provided along the upper edge 16 in addition to being built in the upper edge 16.

  The shape of the bottom of the bag body 15 may be, for example, a gusset that is folded in an inverted V shape.

  In the above-described configuration, the side having the flap portion 12 is the front surface of the packaging bag 11, but the side having the flap portion 12 may be the back.
