Description

    The present invention relates to packaging technology, and in particular to the field of manufacturing packaging bags having a palm joint portion on the bag body, and the transportation, storage, assembly, and packaging products using the packaging bags. Providing and selling equipment, equipment, and tools necessary for manufacturing, materials necessary for those materials, machinery and parts, such as wood, stone, various fibers, plastics, various metal materials, etc. Fields to be provided, fields of electronic components incorporated in them and control-related equipments integrated with them, fields of various measuring instruments, fields of the equipment and power machines that move the instruments, electricity as energy and energy that is an energy source, Fields generally referred to as industrial machinery, such as the field of oil, as well as testing and researching these facilities and equipment, fields related to their display, sales, import and export, Results of their use, facilities for making them, fields related to the collection and transportation of garbage generated by the operation of equipment, etc., as well as recycling fields that efficiently reuse these garbage There are no new technical fields that cannot be envisaged, and there are no unrelated technical fields.

(Points of interest)
Heat-welding to a palm-shaped mold projecting the vertical strips of a predetermined width along the longitudinal direction (length dimension direction) of both edges of the rectangular synthetic resin sheet along the longitudinal direction (length dimension direction), A tubular bag body is formed as a joint band-like back-pasted part, and the transverse belt-shaped regions along the width direction of one end edge of the tubular bag body are thermally welded together. After storing the bag body, from the unsealed other end opening of the bag body, after receiving confectionery such as cookies and chocolate, for example, the lateral belt-like area of the other opening edge of the bag body is heat-sealed The manufactured pillow-type packaging bag has a V-shaped or U-shaped cut end on either or both of the longitudinal direction (length dimension direction) end of the packaging bag and the edge of the horizontal belt-like seal portion. Or when the confectionery of the contents is taken out as if it were formed with multiple cuts lined up in a saw blade shape over the entire width The packaging bag can be easily opened from the cut provided in any of these formats, and it is convenient in that a special mechanism is not required for the opening if the product provider knows It is a packaging form.

    However, for consumers who have purchased such products, when they leave the confectionery in the bag, it is necessary to seal and store the confectionery so that the confectionery is not damp and dust does not enter the bag. Therefore, cellophane adhesive tape, rubber bands, clips, clothespins, etc. will be used for sealing, but if the scene is at home, it will occur at the corner, other places outside the house, or outdoors. However, these sealing means do not remain, and inconvenience is caused as a container in these use stages, while at the stage of consuming all the contents of these packaging bags, the foods are quality protected, This type of packaging bag made for management has the property that various films such as waterproofness, gas barrier properties, and light-shielding properties are laminated and rich in elasticity, and can be easily restored to the original bag shape. Most of them are used by those who want to efficiently use the volume of the box or bag by restoring it quickly even if it is rounded down or folded and thrown away to increase its volume. It also has a nasty problem that is against your will.

(Conventional technology)
Considering such a situation, for example, as represented by those proposed in the following Patent Documents 1 (1) to (3), an opening / closing chuck or an adhesive layer is provided on the back sticking part. What can be resealed after opening the back pasting part of the packaging bag, or a part of the back pasting part of the packaging bag or the trunk part of the bag as seen in Patent Document 2 (1) to (9) And the like that can be removed in the form of a strap, which can be easily opened or the contents can be easily removed.

However, those having an open / close chuck or an adhesive layer on the back sticking part as shown in the former Patent Documents 1 (1) to (3) are resealed after opening and the foodstuffs are sanitized. Even if it is certainly effective to preserve, it will increase the manufacturing cost compared to the packaging bag described above, not only is not suitable as a packaging bag for snacks often eaten at once The drawback of increasing the bulkiness when discarded is not solved at all as in the case of the packaging bag described above, and the packaging bag represented by the latter patent documents 2 (1) to (9). The packaging bag that is very easy to open by making it possible to open the back affixed part or part of the bag body part so as to be removed in the form of a strap. Open area Although it has the effect of making it easier to take out the contents, it is extremely difficult to reseal, making long-term storage using the opened packaging bag almost impossible In addition, it is difficult to re-seal a packaging bag that is opened so as to wrap around the bag body in a strap shape. However, in all cases, it was difficult to re-seal the packaging bag opening end, and it was difficult to seal the bag with a drawstring shape.

(Awareness of problems)
In this way, it is difficult to sanitize the contents of the packaging bags made of various synthetic resins that have been proposed so far after they are opened, and it is difficult to store the contents in a sanitary manner. It is easy for the product provider to return to its original shape, and it has the disadvantage that it easily increases the bulk of the cocoon and is disadvantageous in terms of efficient processing and cocoon reduction, but it is convenient for the product provider. There has been a great deal of problem with the circumstances in which form has been prioritized, and in particular, the problem of culling has been taken up as an important issue in building a smooth daily life. Even if these packaging bags are not, considering the amount consumed nationwide, it is not a problem that is left as it is.

The basic structure of the present invention, which is configured to be superposed in a sheet shape and then rolled up into a roll shape and then operated so as to bind and bind the binding string around the center outer periphery of the roll-shaped packaging bag. This is a packaging bag disposal method for packaged goods using any one of the above packaging bags.

    As described above, according to the packaging bag of the present invention, unlike the conventional ones, the back belt-like vertical seal portion linear weak portion in the production line for the conventional packaging bag has the unique characteristic configuration as described above. It is possible to produce more economically than packaging bags equipped with a resealing chuck, by simply adding any of a roll cutter, a laser device or a high-frequency device for processing. The product to be packaged is accommodated, and the other end belt-like horizontal seal portion is formed and sealed in a pillow type, and the packaged product included in the present invention can be efficiently manufactured. Open the vicinity of the belt-like horizontal seal on either side of the other end, take out a part of the product to be packaged, and then remove it from the packaging bag back belt-like vertical seal, and then excise and separate it according to its linear fragile part Use the The packaging bags that can be bound and resealed, and have been used after all the items to be packaged have been taken out, are compressed into a roll shape, and then tightened by binding the binding string around the outer periphery of the bag. It is possible to dispose of the bag, and it is possible to reliably prevent the bag from returning to its original shape, and to obtain an excellent feature that has a great effect on reducing the amount of bag.

    In addition, if the linear weakened part consists of a straight sewing hole that runs vertically in the longitudinal direction at an appropriate position within the specified width dimension range of the backband-like vertical seal part, the thickness dimension of the backband-like vertical seal part Compared with the one where only the linear part of the linear weak part is set thin, it can be cut and separated accurately even with a weak force at each step, and the binding string breaks in the middle of its full length dimension, It is possible to more reliably prevent the bag body from cracking and to maintain economically stable packaging quality.

    The back belt-like vertical seal portion has a width of 10 to 15 mm, and a linear weak portion is formed at a position 5 mm from the outer edge in the transverse width direction. It can be produced economically by reducing the amount of synthetic resin film used when the dimension exceeds 15 mm, and the width of the tying string (5 mm) is less than when the width is less than 10 mm. Can be ensured sufficiently, and the remaining adhesive width (5 to 10 mm) after excision of the binding string can be sufficiently ensured, and it is possible to achieve both high economy and high quality, and for conventional packaging bags. There is no need to change the dimensions of the synthetic resin film, and an excellent effect is obtained that the film can be used as it is.

    The backband-shaped vertical seal portion has a predetermined lateral width direction outer edge directly adjacent to the linear weakened portion, and a piece of tear tape that is integrally attached along a portion that becomes a binding string after excision is When cutting and separating the binding string from the seal part, the tear tape is gripped and the tearing operation is performed, so that the tearing force is more reliably concentrated at the tearing point of the linear fragile part, and the crack is removed from the bag body. Advantages that prevent the strap from progressing and reinforce the binding strap itself to prevent the binding strap from breaking in the middle of its full length or narrowing the width. Is obtained.

    In addition, according to the packaging bag resealing method using the packaging bag of the present invention, the inside of the opening is equipped with a chuck for resealing, an adhesive layer, etc., if it is a conventional packaging bag It was extremely difficult to re-seal other than the ones that had been used, and it had to be resealed by various means such as rubber bands, cellophane adhesive tape, and clips, but this problem could be solved all at once. Even in places where processing means such as going outside are not required outside the home, the binding object can be easily excised from the backband seal part of the packaged product according to the line weakened part and remains in the packaging bag. The other end / one end of the band-shaped seal part opposite to the other part of the product is moved to the hook, and one of the one end / other-end band-shaped seal part of the opened bag is moved. Close or close the middle of the bag Has the excellent effect that it can be easily resealed at each stage by twisting and lifting the thin string-like part around its outer periphery and then tightening it tightly. Can demonstrate.

    Further, according to the packaging bag disposal method for packaging products using the packaging bag of the present invention, in the case of a conventional packaging bag, all the products to be packaged are taken out and rolled up or folded when used. Although it is compressed and compacted as much as possible and dumped in a box, etc., it has the disadvantage that it expands and expands due to the elastic restoring force of the packaging bag, which increases the amount of bag. Solve the problem, and easily remove the tying strap from the back strap of the packaging bag according to the line weakened portion, and also remove the air and the remaining contents from the opening of the packaging bag. It is made to operate in such a way that it is tightly stacked and rolled up into a single sheet and then rolled up tightly, and then tied around the central outer periphery of the roll-shaped packaging bag. In a box When so as to disposal, by tight binding by 該緊 Bakuhimo, development of the packaging bag, the return is reliably suppressed, and which exhibits a large feature that becomes what to reliably achieve the reduction of waste volume.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
The synthetic resin film is a soft material for packaging bags, and at least the back belt-like vertical seal part of the packaging bag, and the parts forming the belt-like horizontal seal parts at one end and the other end are thermoplastic for hot welding. It is necessary to use a resin film or to form an appropriate adhesive layer. More specifically, ionomer film, polyethylene film, polyvinyl chloride film, polyvinyl alcohol film, polypropylene film, polyester film, polycarbonate film , Polystyrene film, polyacrylonitrile film, ethylene vinyl acetate copolymer film, ethylene-vinyl alcohol copolymer film, ethylene-methacrylic acid copolymer film, nylon film, cellophane, etc., or laminated film Can In other words, it is a multilayer film for packaging, OPP / PE, OPP / EVA, OPP / L-LDPE, OPP / CPP, OPP / EVOH / PE, OPP / PVA / PE, OPP / AL / PE, OPP / PE / VM / PET / PE / CPP, OPP / VM / CPP, KOP / PE, KOP / EVA, KOP / L-LDPE, KOP / CPP, PET / PE, PET / EVA, PET / L-LDPE, PET / CPP, ON / CPP, KON / PE, KON / CPP, PET / VM / PET / PE, PET / VM / PET / EVA, PET / AL / PET / L-LDPE, PET / AL / PE, PET / AL / CPP, PET / PAN, (AL: aluminum laminate, VM: aluminum vapor deposition) or the like can be used. Films and sheets other than synthetic resin materials such as metal foil can be laminated, and can be replaced with paper bags or metal foil bags that do not use synthetic resin depending on the application. .

  The cylindrical bag body formed from these synthetic resin films is composed of a front film portion corresponding to the front (top) of the finished packaging bag and a back film portion corresponding to the back (bottom) surface. Both of the front and back film portions are composed of a single synthetic resin film that is continuous with each other, and is joined in a cylindrical shape by a backband-like vertical seal portion, but if necessary, a plurality of Sheets of synthetic resin can be attached to each other, processed into a single film, and formed into a packaging bag.

    The packaging bag appropriately protects the packaged item by sealing the product to be packed in a vacuum state, sealed with air or inert gas, various liquids, etc. A function to enable packaging, and a predetermined width dimension range at both edges in the width direction of a synthetic resin film is pasted on a palm-shaped type projecting outwardly across the lengthwise direction, and a backband-shaped vertical seal part The cylindrical bag body is formed, and one end edge predetermined vertical dimension range of both the front and back film portions in the longitudinal direction of the cylindrical bag body is pasted to form one end belt-like horizontal seal portion And a linear fragile portion for easy excision that vertically cuts in a longitudinal direction at an appropriate position within a predetermined width dimension range of the backband-shaped seal portion, and the cylindrical bag body in the longitudinal direction The other end is the opposite side of the belt-like horizontal seal part In addition to accommodating the product to be packaged from the end opening and forming the other end band-like horizontal seal portion at the other end opening so that it can be sealed in a pillow type, the same back belt-like seal at the stage of completing the packaged product For example, as shown in the examples to be described later, it is possible to form a gusset portion at an appropriate position of the cylindrical bag body, and to synthesize It is a bag material in which the back belt-like seal part linear weak part of the packaging bag is formed during the continuous bag making and packaging process from the resin roll film material. It can be set as the packaging bag which can acquire an effect.

    If these packaging bags and packages are expressed as being produced during the process of making bags and packaging from a synthetic resin roll film material at once, for example, during the bag making process from a synthetic resin roll film, Along with forming a cylindrical bag body part as a backband-like seal part by sticking predetermined width dimension ranges at both edges of the roll film width direction in the palm-shaped shape projecting on the outer side across the lengthwise direction Forming a linear fragile portion for easy excision that cuts in the longitudinal direction in an appropriate position within a predetermined width dimension range of the back belt-shaped seal portion, and the back belt-shaped seal portion is disposed at an appropriate position on the back surface of the cylindrical bag body portion. A predetermined longitudinal dimension range of both the front and back film portions of the longitudinal direction end of the cylindrical bag body portion is adhered to each other so as to form a one-end belt-shaped seal portion, and the one-end belt shape of the bag body portion Front and back flanks separated from the seal part by a vertical dimension equivalent to the storage part The predetermined longitudinal dimension ranges of both the rum parts are pasted together, the other end belt-like seal part is formed and sealed in a pillow type, and the bag body part accommodating part is put into any appropriate stage until it is sealed in the pillow type. After storing the product to be packaged in the corresponding space, the other end band-shaped seal portion is cut off from the subsequent roll film to obtain one packaged product, and both end edges of the roll film in the lateral width direction are in the shape of a palm. After packing and forming the back belt-like seal part, forming the one-end / other-end belt-like seal part and sealing the pillow type in any appropriate stage, the other end A process for producing a packaged product, in which the same process until the strip-shaped seal part is separated from the subsequent roll film to produce one packaged product is successively repeated to produce a large number of packaged products, and this production Made by method It can be shown as been packaged product.

    The backband-shaped vertical seal allows the edges in the widthwise direction of the synthetic resin film to be joined across the lengthwise direction. Attached to the palm type that protrudes toward the outer edge across the widthwise direction of both edges in the width direction of the synthetic resin film, and is equipped with a backband shape. It is assumed that a linear fragile portion for easy excision that is longitudinally cut in the longitudinal direction at an appropriate position within a predetermined width dimension range of the vertical seal portion is formed, and even after the binding string is excised from the linear fragile portion as a boundary In addition, the remaining portion of the backband-shaped vertical seal portion must maintain the packaging bag shape and be able to ensure a sealed connection state of the backband-shaped vertical seal portion, as shown in the examples described later, Full packaging and resealing functions and compactness for disposal In consideration of tight binding stability, such as the width of the backband-shaped vertical seal portion, the width dimension is set to 10 to 15 mm, and a linear weak portion is formed at the position of the flange within 5 mm from the outer edge in the width direction. It is desirable to use a tear tape (opening tape, tear tape, cut tape, etc.) along the part that becomes the binding string after excision. It can be a unit that is integrally mounted.

    The line weakened portion functions to make it possible to easily cut the binding string from the backband-shaped vertical seal portion, and concentrates the stress when cutting the binding string from the backband-shaped vertical seal portion so as to tear it. It shall be possible to cut from an appropriate linear part, for example, using a roll cutter, a laser processing device, a high-frequency processing device, etc., at a suitable position within a predetermined width dimension range of the backband-shaped vertical seal portion. It should be formed by forming a groove-like thin portion in the longitudinal direction or by forming a sewing machine hole.

    The binding strap is integrated into the backband-shaped vertical seal of the package and its packaging bag, and can be used at any stage of use, such as immediately after opening or after taking out some products to be packaged. It is possible to tie and tie up near the opening edge of a certain packaging bag, or to compress the packaging bag that has been used after taking out all the products to be packaged into a roll and tighten it It must be strong enough to withstand excision from the backband-shaped vertical seal portion and the subsequent tying operation of the packaging bag. To secure a sufficient length, the backband-shaped vertical seal Should be set to a length corresponding to the entire vertical dimension of the portion, but may be set to a length corresponding to a part of the vertical dimension of the backband-shaped vertical seal portion as necessary. Change the shape of the outer and linear weak parts so that they can be separated into multiple pieces And those, the tear tape and reinforcing yarn, resin reeling, by integrating such plastic wire reinforced, it is possible, and the like that enhance the bondage performance.

    The one-end / other-end belt-like horizontal seal part can seal both ends of the cylindrical bag body made of a synthetic resin film in a hermetically sealed manner, depending on the packaging purpose of the packaging bag. If an adhesive is used, an adhesive of an appropriate type and material that does not adversely affect the product to be packaged must be selected. Is made of a material that can be heat-welded, such as a thermoplastic resin film, on both the front and back films of the synthetic resin film, or a material layer that can be heat-welded to the adhesive surface It should be
